Night agent — its own notes

The unattended agent on the VM (skills/night-agent.md) writes a handoff block at the TOP of this file at the end of every run, newest first. It is the night agent's file: people do not edit it, and the agent writes in no one else's docs/state/<handle>.md.

What a block claims is the agent's account. What is actually DONE is the runner's verdict per task in ~/samo-night/NIGHT-TASKS.md on the VM, decided by each task's Done when: command — read that first.

Its work lives on a branch on the VM that cannot push; the checklist for bringing it in is docs/state/HANDOFF.md §20.

▶ HANDOFF 2026-10-19T21:07:00Z (night agent, branch agent/2026-10-18)

1. Do first. Open docs/state/HANDOFF.md §22's "Rows 8–12 — the owner's apply-in-order checklist" (just above the per-task table) and follow it top to bottom: apply 0230 → 0231 → 0233 → 0232 to samo-dev (already done this queue, re-confirm), then production, with the proof named after each step — note shop0230-samo-year.sql is 32/32, not the 31/31 an earlier commit this same queue recorded (caught by a later task re-running it live, not by trusting the written number).

2. Ready to use vs. still a design. The whole queue (tasks 8–12) is WRITTEN and proved on samo-dev, NOT ON PRODUCTION — this agent has no production credential (confirmed by every task this queue; samo-dev's token answers 403 there) and cannot push, deploy, or run Apps Script. Nothing in this run changed that.

Ready, pending the owner's apply/deploy: migrations 0230 (Shop gets a samo year), 0231 (stats-retention rollups), 0233 (fixes a real bug in 0231 — a weekly prune without a day-aligned cutoff silently lost ~20 of every ~24 days of analytics; MUST apply after 0231, before 0232), 0232 (Passport↔team_term bridge, หน้าฝ่าย "แก้ไขล่าสุดโดย", accounts activity-by-year) — all proved green on samo-dev this queue (32/32, 31/31, 7/7, 22/22 respectively, each re-run live more than once rather than trusted from a prior count). ระบบบ้าน's graduation (task 8) needed no migration — it is derived in JS (isGraduated()), not stored.
Written, never run anywhere: the VM systemd timer (server/stats-retention.*) for the stats prune — pg_cron is not installed on this project, so until the owner installs this timer OR enables pg_cron, nothing prunes analytics_events/claude_usage_samples (today's behavior continues; nothing regresses by waiting). tools/browser/shop-checkout-navigate-away.mjs (written, never run — no Chrome/network in this sandbox).
Design only, not touched this queue: everything in docs/YEAR-ROLLOVER.md beyond what tasks 8–10 actually built.

3. What did not happen, and why. AGENT_UNRUN=0, AGENT_ASKS is empty — every queued task (8–12) ran and finished, and none ended by asking a question nobody was awake to answer. AGENT_STOP: queue finished. But three of the five did not finish normally in one pass — flagging them by name, as the runner's own report insists ("ต้องให้คนดู 3 งาน … อย่าสรุปว่าคืนนี้ เรียบร้อย" — 3 tasks need a human look, don't call tonight clean):

Task 8 (ระบบบ้าน + ข้อมูลของฉัน) — cut off mid-run by the quota once (392017a), resumed the same queue and reached a green Done when: check. Its own /scrutinize pass ran and is recorded in HANDOFF §22 row 8.
Task 9 (SAMO Shop) — cut off/attempted twice (Attempts: 2 in NIGHT-TASKS.md), resumed and finished; its own resumption's /scrutinize pass found and fixed a real bug in itself (the "ต้องจัดการ" admin tiles counted all years while the views they opened into were year-filtered) — a case where the cut-off-and-resume cycle actually caught something a single clean run might not have, since the bug was in code the WIP commit itself had just written.
Task 10 (Passport/หน้าฝ่าย/announcements/stats/accounts) — cut off twice (Attempts: 2), and its two WIP commits built everything the brief asked but neither wrote the task's own docs/state/night-agent.md heading the Done when: check greps for, nor ran its own /scrutinize pass. Tasks 11 and 12 both read and flagged this gap without closing it; a later run in this same session ("10 RESUMED", commit e2e6358) finally wrote the missing heading, re-ran all three of its proofs live, and — in the same pass — npm test caught a real staleness bug: STATE.md said "67 of 72 LIVE PROOFS" when tools/run-proofs.mjs had registered 73 since a prior commit added one without updating this sentence (state-handoff.test.js was red). Fixed. Recommend the owner skim this task's block specifically (docs/state/night-agent.md, "Task 10") — not because anything in it is known-wrong, but because it is the one piece of this queue that went through the most re-entry before closing, and a second human read is cheap insurance.

Tasks 11 (scrutinize + bug scan) and 12 (handoff checklist) each finished cleanly in one pass (✓ in the queue report).

4. Needs a human decision (every one is already written out with its consequence in HANDOFF §22's per-decision list below the table — this is only the index):

Apply 0230→0231→0233→0232 to production now, or wait and re-review first? Recommendation: apply — all four are proved on samo-dev this queue (most re-run live more than once, not just read off a recorded count), task 11's dedicated scan found nothing blocking, and the longer they sit unapplied the more STATE.md's "samo-dev ONLY, NOT production" caveat is pure downside with no offsetting benefit.
systemd timer vs. enabling pg_cron for stats retention? Recommendation: the timer (already written, matches the existing backup-timer pattern) — pg_cron is a one-click Database→Extensions action only the owner can take, and the migration's own header makes the swap a one-line change later if preferred, so neither choice forecloses the other.
ระบบบ้าน graduation: derived (isGraduated()) vs. the originally-proposed stored students.graduated_at column? Already built as derived — the recommendation task 8 made and this run is not revisiting — because a stored flag can drift from the rule that computes it (class 6, "fill-once means never-correct"), and the JS already has one home (study-year.js) every reader shares.
account_dashboard()'s year filter defaults to "ทุกปี" (unscoped) — recommendation in HANDOFF §22: leave it, since a cross-system lifetime account view is arguably more useful unscoped than a single system's own order/ticket list; flip is a one-line change in src/js/accounts/admin.js if the owner disagrees.

5. Could not verify.

Nothing against production — no production credential exists in this environment (samo-dev's token answers 403 there); every "applied" claim above is scoped to samo-dev only.
npm run handoff:check still crashes, same as every task this queue: fatal: ambiguous argument 'origin/agent/2026-10-18..HEAD' (this branch has never been pushed, so origin/agent/2026-10-18 doesn't exist to diff against) followed by an ENOENT reading a memory-index path the script hardcodes under ~/.claude/projects/… — this session's real memory store is ~/samo-night/memory/ instead, a different path entirely. Not re-diagnosed — documented identically by tasks across this whole queue. Substituted direct checks, re-run fresh by this handoff step: npm test — 173 files / 2984 tests, green. npm run build — both entries (public/admin + Passport) clean. git status — clean.
No browser was driven this step — the shop checkout navigate-away walk and a real-phone look at the house/accounts UI remain code-trace verified only, per tasks 9/10's own notes.
Apps Script / Google Drive — confirmed by git diff origin/main..HEAD -- appscript/ being empty that this queue needed no GAS step; not independently exercised (no Google credential in this environment, same as every prior queue).

Task 12 — HANDOFF: the owner applies, deploys and decides from this (2026-10-18)

What this run built: nothing new to apply — a documentation pass over docs/state/HANDOFF.md §22 and STATE.md, per task 12's own brief. No migration (0229 and 0233 stay unused gaps, as tasks 8 and 11 already left them), no new proof, no code.

What it found and fixed, beyond just writing the checklist:

Row 10 was stale. It still read "QUEUED 2026-10-18" even though tasks 9 and 11 had already recorded 0231/0232 as built, proved (31/31, 22/22), and reviewed — task 11's own block explicitly flagged this gap ("task 10 never got its own /scrutinize write-up or HANDOFF row-10 update... task 12 should close that") and this run does, with the real migration numbers, proof names, and the apply command.
One real miscount, found by re-running rather than trusting the recorded number (the exact discipline .claude/rules/mistakes.md class 7 asks for — "verify from the authority, not the revoke you just wrote"): both task 9 and task 11 recorded tools/shop0230-samo-year.sql as "31/31" on samo-dev. Running it live during this task returned 32 PASS rows (confirmed twice, and cross-checked against the SQL file's own 32 distinct step strings — the SQL source has always had 32, so the "31" was a hand-count error from the start, not drift). stats0231- retention (31/31) and passport0232-bridge-dept-editor-accounts (22/22) were independently re-counted the same way and both matched what tasks 9–11 already recorded — only the shop proof's digit was wrong. Corrected in docs/state/HANDOFF.md (the apply-checklist's own commands, and a note pointing at rows 9/11 rather than silently rewriting their prose) and in STATE.md's task-9 line; task 9's and task 11's own blocks in this file are left as their own historical account, uncorrected, per this file's own rule that a block is "the agent's account," not a second home for a number that has one now in HANDOFF/STATE.
Verified the migration apply ORDER actually matters, not just convention: read supabase/migrations/0232_passport_team_term_bridge_ and_dept_editor_info.sql directly — its account_dashboard() rewrite queries public.shop_orders filtered on samo_year_be, a column only 0230_shop_orders_get_a_samo_year.sql creates. So 0232 MUST be applied after 0230, not just "sometime in the 0229–0233 block" — this was not previously stated anywhere as an explicit ordering constraint, only implied by migration number. Written into the apply-in-order checklist as step C's own comment.
Confirmed no GAS step belongs in this queue's checklist — git diff origin/main..HEAD -- appscript/ is empty across all of tasks 8–12's commits, so npm run deploy:gas is correctly absent from the checklist.

Added to docs/state/HANDOFF.md §22: a new "Rows 8–12 — the owner's apply-in-order checklist" section (migrations 0230→0231→0232 with proof commands dev-then-prod for each; the VM systemd timer install for stats retention; the one-line confirmation no GAS/deploy:gas step is needed; a "what to click, at 390px too" browser-verification table per system; and every overturnable decision from tasks 8–11, one line each with the consequence of flipping it — e.g. ระบบบ้าน's derived-not-stored graduation, shop_order_totals()'s current-year rescoping with a null fallback, the systemd-timer-vs-pg_cron choice, account_dashboard()'s accurate-but- unscoped "ทุกปี" default). Corrected row 10 in place. Updated STATE.md with one line each for tasks 8, 10 and 12 (task 9 and 11 already had lines) — 249 lines, under the 260-line ceiling state-handoff.test.js enforces.

/scrutinize run on this task's own diff (git diff 2c2d2f9..HEAD -- STATE.md docs/state/HANDOFF.md): traced the 0230→0232 dependency claim to the actual SQL (confirmed above); re-ran all three proofs live against samo-dev rather than trusting any recorded count (found and fixed the shop0230 miscount above); confirmed every migration/tool/server file path named in the new checklist actually exists on disk; confirmed the new row 10/row 12 text does not contradict state-handoff.test.js's migration- high-water-mark or proof-count checks (npm test, full suite, green); confirmed HANDOFF.md names no commit sha (a dedicated guard — the first draft of row 10 named two, caught by the test, reworded to describe the commits without quoting their hex). No other finding — this is a docs-only task and the content it documents (tasks 8–11's actual code) was each task's own job to get right, already reviewed by task 11.

npm test: 173 files / 2982 tests, green, both before and after this task's edits. npm run build: clean, both entries. git status: clean after this task's commit.

npm run handoff:check verdict — same known crash as every prior task this queue (ENOENT reading ~/.claude/projects/-home-ubuntu-samo-agent/memory/MEMORY.md; this session's real memory store is ~/samo-night/memory/ per this session's system preamble; also origin/agent/2026-10-18 reported unknown since this agent cannot push). Not re-diagnosed — already documented by every earlier task this queue. Substituted direct checks: npm test, npm run build, git status, and the three migration proofs (shop0230-samo-year, stats0231-retention, passport0232-bridge-dept-editor-accounts) re-run live against samo-dev with → project: xibugtlsphcfuvstnxxh (samo-dev) confirmed in each run's output.

Commands the owner runs next: read docs/state/HANDOFF.md §22's new "Rows 8–12 — the owner's apply-in-order checklist" section top to bottom — it is written to be followed in order, not summarized again here. In short: review the branch, apply 0230→0231→0232 to samo-dev (already done, re- confirm if it's been a while) then production with a proof after each, install the optional stats-retention VM timer, deploy the bundle, click through the browser-verification table, then read the decisions list before overturning anything tasks 8–11 decided.

▶ HANDOFF 2026-10-13T20:53:00Z (night agent, branch agent/2026-10-14)

1. Do first. Open docs/state/HANDOFF.md §22, then docs/YEAR-ROLLOVER.md. Do not apply any of migrations 0219/0220/0224 to production yet — 8 of 12 queue tasks have not run (see §3), and task 11 is specifically a bug scan of this whole branch that has not happened. If the PR-dashboard relief is wanted NOW regardless (the owner's own named pain point, 290 crowded tickets), 0219+0220 are self-contained and independently proven (see §2) and can be reviewed and applied ahead of the rest — 0224 (ทีม SAMO handover) changes a real workflow's behavior (auto-archive on handover) and is better read first.

2. Ready to use vs. still a design.

Proven green on samo-dev, NOT on production (no production credential exists in this environment — see §5):
- Migration 0219 — current_samo_year(), samo_year_be_default() trigger, start_team_term(). Proof year0219 reported 23/23 by task 2's own run; not re-run by this handoff step (budget call, see §5).
- Migration 0220 — pr_tickets.samo_year_be + PR Staff Dashboard year picker/export/past-year lock. Proof pr0220 — re-run fresh by this handoff step: 23/23 PASS against project: xibugtlsphcfuvstnxxh (samo-dev).
- Migration 0224 — ทีม SAMO handover re-gated to team_edit (closes a real authz gap: ~300 VIEW-only accounts could previously call the handover RPC), auto-archives the outgoing term. Proof team0224 reported 14/14 by task 4's own run; not re-run by this handoff step.
- skills/year-rollover.md (the runbook) and src/js/samo-year.js (the one shared year picker every task must reuse) both exist and are used by tasks 2/3/4 already.
Written, not deployed, not exercised against anything real:appscript/prform.gs's per-year Drive subfolder code and tools/pr-organize-drive-by-year.mjs (the dry-run mover) — this environment has no Google/Apps Script credential, so NEITHER has ever run against real Drive, by any task tonight. GAS deploy (npm run deploy:gas) and the frontend bundle deploy are both owner-only, unexecuted.
Design only, no code: everything in docs/YEAR-ROLLOVER.md beyond what tasks 2/3/4 actually built — VitalSound, SAMO Shop, หนังสือโครงการ, ระบบบ้าน, Passport, หน้าฝ่าย, announcements, stats/retention, and the whole backup/export/deletion layer are DECIDED IN PROSE, not implemented.
A bookkeeping gap found and fixed by this handoff step, not a code change: task 3 (PR dashboard) was fully built, proved, and committed earlier in this same session (3978eeb, b998c52) but the runner kept reporting it todo because the required ## Task 3 heading was never written to this file. Added it below, with the fresh proof re-run as evidence — no PR code was touched. The next time the runner evaluates this queue, task 3's Done when: should pass without anyone redoing the work.

3. What did not happen, and why.AGENT_UNRUN=8, AGENT_ASKS is empty (no task ended by asking a question nobody was awake to answer), AGENT_STOP: quota: รอบ 5 ชั่วโมงนี้ใช้ไป 92% แล้ว — รอรีเซ็ต 2026-10-13T23:59:59.814Z. Verbatim queue report from before this handoff step ran:

✓ [done] 1. PLAN — decide the SAMO-year model for every system (design doc, no app code) — ผ่านวิธีตรวจ
! [done] 2. The ONE SAMO year — foundation, admin control, runbook — ถูกตัดกลางทางรอบก่อน แล้วทำต่อจนผ่านวิธีตรวจ
! [todo] 3. PR Form — a dashboard per SAMO year, export, Drive per year — ลองแล้ว 1 ครั้ง ยังไม่ผ่าน
✓ [done] 4. ทีม SAMO + จัดการทีม + permissions handover + Discord roles — ผ่านวิธีตรวจ
! [todo] 5. Backup, export, deletion — the data-safety layer every system uses
! [todo] 6. VitalSound — per-year board and staff view, PDPA retention
! [todo] 7. หนังสือโครงการ — ปีงบ completeness, Drive per year, seats across years
! [todo] 8. ระบบบ้าน + ข้อมูลของฉัน — academic-year rollover, graduates, the next รุ่น
! [todo] 9. SAMO Shop — orders and products across seasons
! [todo] 10. Passport, หน้าฝ่าย, announcements, stats, Claude booking, accounts
! [todo] 11. SCRUTINIZE + BUG SCAN of everything on this branch, and of 2026-10-13's work
! [todo] 12. HANDOFF — the owner applies, deploys and decides from this
ต้องให้คนดู 10 งาน (ไม่ได้จบแบบปกติในรอบเดียว) — อย่าสรุปว่าคืนนี้เรียบร้อย

As fixed by this step, line 3 above is stale — the code was done, only its record was missing (§2). Still genuinely undone: tasks 5, 6, 7, 8, 9, 10, 11, 12 — all eight never started. None of these are "attempted and failed"; the run was cut off by the 5-hour quota after task 4 finished, before task 5 could begin. This means:

No backup/export/deletion layer exists yet for ANY system (task 5) — the owner's explicit questions about deleting, backing up and exporting data are answered IN PROSE in docs/YEAR-ROLLOVER.md only, nothing runnable.
VitalSound, Shop, หนังสือโครงการ, ระบบบ้าน, Passport, หน้าฝ่าย, announcements, stats and accounts have NONE of the per-year work the owner asked for yet — only PR and ทีม SAMO do.
The branch has not had its own dedicated bug-scan pass (task 11) — only each task's own self-scrutinize (which already caught and fixed two real bugs: task 2's genesis-row reopen bug, task 3's past-year-lock-keyed-on- filter bug). A whole-branch pass may find more, especially interactions BETWEEN tasks 2/3/4's migrations.
Task 12's own deliverable (making docs/state/HANDOFF.md §22 the owner's exact apply-in-order checklist with every decision flagged as overturnable) has not run — §22 as it stands was written incrementally by tasks 1/2/4 and is usable today, but was never given task 12's dedicated polish pass.

Per NIGHT-TASKS.md's own budget (6 runs, 1 night used, until 2026-10-14T09:00:00Z / weekly reset 16:00 ICT), the runner is expected to keep firing further runs automatically after the 5-hour quota resets (2026-10-13T23:59:59Z) — no owner action is required to continue the queue. This handoff step took no action to pause or resume it.

4. Needs a human decision.

Apply 0219+0220 to production now (PR relief), or wait for task 11's bug scan first? Recommendation: if the 290-ticket crowding is urgent, apply now — both are independently proved on samo-dev and self-contained (no other task's migration depends on them going first, only the reverse). Otherwise, default to waiting for task 11, since it is specifically scoped to catch cross-migration interactions this handoff step did not check for.
Apply 0224 (ทีม SAMO handover) now? Recommendation: read docs/state/night-agent.md's own "Task 4" block first — it changes what "ตั้งเป็นปีปัจจุบัน" actually DOES (auto-archives the outgoing term inline) and closes a real authz hole. Low risk, but it's a workflow behavior change a staffer should know about before it ships, not just a schema add.
Let the automated queue keep consuming its remaining budget unsupervised? Recommendation: yes — AGENT_ASKS is empty across all four runs so far, meaning nothing has needed a judgment call it couldn't make itself, and every task that finished did so with a green proof, not a guess.
npm run handoff:check is broken in this environment (see §5) — fix the memory-path assumption, or leave the two memory stores (interactive session vs. night agent) separate and give the script an escape hatch? Not decided here — this is a tooling question outside tonight's actual feature scope, and guessing at the intended design risked making it worse.

5. Could not verify.

No production database credential exists in this environment at all (measured 2026-10-13: samo-dev's token answers 403 on production). Every production row count cited above and in docs/YEAR-ROLLOVER.md is the measured-on-2026-10-13 facts handed to this queue, not something this step confirmed itself.
npm run handoff:check could not complete — it crashed with ENOENT reading ~/.claude/projects/-home-ubuntu-samo-agent/memory/MEMORY.md (that directory exists but is empty; the night agent's real ~65-file memory store lives at ~/samo-night/memory/ instead, per this session's own system preamble — the two were never the same store) and separately reported origin/agent/2026-10-14 as unknown (expected: this branch has never been pushed, since this agent cannot push). Ran with --local too; same crash, so the flag does not route around it. Substituted direct checks instead: npm test (2716/2716 green), npm run build (clean), and a fresh run of tools/pr0220-year-filter.sql against samo-dev (23/23, confirmed the project ref printed was samo-dev's).
Did not re-run year0219-samo-year.sql or team0224-handover.sql this step — budget call, given the quota is at 92% for this 5-hour window; relying on tasks 2's and 4's own commits and STATE.md's record of having run them green on samo-dev earlier in this SAME session, not a stale claim from a prior night.
Apps Script / Google Drive: zero credentials available, zero real exercise of the per-year folder code or the mover tool, by any task tonight — everything Drive-related is verified by code reading only.

Task 6 — VitalSound: per-year board/staff view, PDPA retention (2026-10-14)

What this run built. Migration 0221, applied to samo-dev only:

vs_tickets.samo_year_be smallint — the same stored-at-INSERT shape as pr_tickets.samo_year_be (0220): samo_year_be_default() trigger (0219), one-time backfill for the 119 existing rows from timestamp (never created_at, same reasoning 0220's header gives). RLS unchanged — year is a filter, never an access boundary, per docs/YEAR-ROLLOVER.md § VitalSound.
No past-year edit lock, unlike PR. The design doc never asks for one, and a real workflow argues against it: a duplicate filed THIS year can merge into a canonical ticket filed LAST year (edge case 14), and staff routinely need to write that canonical row regardless of its filing year. Locking it would fight the merge feature the design doc names by example.
vs_scrub_closed_tickets(p_year, p_months default 24) — the PDPA anonymiser § VitalSound asked for. FUNCTION ONLY: nothing calls or schedules it (task 11's job, same as 0222's own export gate). Fails closed on three independent axes (permission, the 0222 export gate, bad input), then overwrites problem/resolution_note on tickets that are filed under p_year, CLOSED right now, older than p_months (updated_at as a conservative proxy — no resolved_at column exists), and not already scrubbed. Never touches public_title/public_note (0072 — the public board never reads problem/resolution_note either, so this changes nothing the board shows, matching "the public board's content stays"). Idempotent via a new anonymized_at column.
NOT scrubbed, flagged rather than silently handled: remarks (the internal timeline jsonb) can also carry a staff-typed name reference. Safely anonymising a jsonb array — keeping each entry's shape while blanking only free text — is bigger than tonight's remaining budget; named in the migration header as a real, open gap rather than claimed as done.
Added data_admin to PERM_CATALOG (src/js/team-vocab.js). 0222 (task 5) shipped the permission key this function and record_year_export both gate on, but it was never added to the catalogue the ทีม SAMO → สิทธิ์ checkbox grid reads — meaning nobody could ever be granted it except by holding role = 'dev'. One line, no admin tab of its own (same pattern as master/passport, which are also absent from ADMIN_FEATURES).
src/js/vs-year.js — the VS-specific pure helpers, mirroring pr-year.js's split (no DOM, no fetch). Moved the ALL_YEARS sentinel into samo-year.js (the actually-shared module) and had pr-year.js re-export it, so VS and PR stop each defining their own copy of the same string — a class-6 drift waiting to happen the moment one changed.
VS staff kanban (vs-staff.js) gets the shared samo-year.js picker as a new facet (#vsStaffYearFilter), defaulting to the current year, persisted across re-entry like the dept/cat/tag facets already are, plus a year chip on each card (shown only in "ทุกปี", same rule as PR's yearFlag).

Caught by this task's own /scrutinize pass before it shipped, not reported by anyone — the one real bug. The first draft keyed "is this ticket closed" on resolution is not null in BOTH the SQL function and the JS filter. Tracing submitStaffAction (vs-staff.js) and the 0074 cascade trigger end to end showed resolution is written ONCE, the first time a ticket closes (0073), and nothing anywhere clears it if a staffer later reopens the ticket to a different status — submitStaffAction's PATCH only ever WRITES resolution inside if (willWriteResolution) (itself gated on isDone), never nulls it, and 0074's cascade trigger clears resolution_note on a mirrored duplicate but never resolution itself. So a REOPENED ticket keeps a stale non-null resolution forever: the original code would have HIDDEN a reopened past-year ticket from the default current-year view (the opposite of "open tickets carry over") and made it ELIGIBLE for PDPA anonymisation while someone is actively working it again. Fixed by keying both the SQL function and vsTicketMatchesYearFilter on status = 'เสร็จสิ้น' instead — the same live signal vs-staff.js's own isDone already uses — keeping resolution is not null only as a defensive AND in the SQL function. Moved DONE_STATUS into vs-year.js so vs-staff.js imports it rather than keeping its own copy, closing the two- homes gap that let the mismatch happen in the first place. Added a REOPENED-ticket case to both the proof and the unit tests as a regression guard. Separate commit (b189193) after the initial build (9368e7a), per this repo's own convention of a fix-commit distinct from the feature commit.

Proof tools/vs0221-samo-year.sql, 34/34 on samo-dev; registered in tools/run-proofs.mjs. Covers: the column/index/trigger/function exist (§0); insert with no explicit year is stamped from current_samo_year(), an explicit year survives the trigger (§A/§B); the backfill resolves from history across a REAL handover, not wall-clock "now" (§C, mirrors pr0220-year-filter.sql §C exactly, sentinel years 2697/2698 — unused by every other proof); the scrub's permission gate refuses a stranger and passes a data_admin holder onto the NEXT gate (§D, paired so a deny-only probe cannot hide a broken ALLOW); the export gate actually refuses an unexported year and opens once record_year_export() records it (§E); five fixtures prove exactly what gets scrubbed and what does not — closed+old (yes), open (no), closed+recent (no, too young), closed+old+different-year (no, scoped to p_year), and REOPENED (no — the regression case) (§F); the public board's public_title/public_note are untouched by the scrub (§H); a second run scrubs zero additional rows (§G).

Decisions made, and what was rejected:

No past-year edit lock (PR's pr-year.js has one) — rejected because the design doc never asks for it and the duplicate-merge-across- years workflow (edge case 14) actively needs to write a canonical ticket from any year, unlike PR which has no such merge relationship.
The public board gets NO year filter or dimension at all — the design doc's own § VitalSound says "the public board's content stays", and a canonical problem can be the merge target of duplicates filed across multiple years (edge case 14), so "which year does this board card belong to" has no single correct answer for a merged problem. Adding one would either pick an arbitrary year (misleading) or require tracking per-duplicate years on the board (a bigger feature nobody asked for tonight). Rejected rather than half-built.
updated_at, not a new resolved_at column, as the scrub's age proxy — rejected adding a column to get an exact "closed at" instant, because the conservative direction (any later touch pushes the scrub window OUT, never in) is the privacy-safe one to be wrong in, and it matches the "no created_at on shop_orders either, use what already exists" precedent elsewhere in this design doc.
year_export_recorded/record_year_export (0222) reused as-is, no VS- specific export gate — exactly the contract task 5 built this for; writing a second gate would be the class-6 mistake task 5's own migration header explicitly calls out avoiding.
Added data_admin to PERM_CATALOG now, rather than leaving it for task 11 — rejected waiting, because this task's own scrub function is the first thing that actually needs a human to be able to hold the permission; leaving it ungrantable would have shipped a gate nobody could open through the UI for an unknown number of further tasks.

WRITTEN, NOT APPLIED to production: migration 0221 and everything it defines. Depends on 0219 (task 2) AND 0222 (task 5) already being applied first — 0222 because vs_scrub_closed_tickets calls year_export_recorded.

Updated STATE.md (migration high-water mark note, proof count 66→67, a one-line task-6 summary in the night-agent block), docs/state/HANDOFF.md §22 (row 4 — VitalSound), src/data/changelog.js (PENDING, staff-facing), docs/mistakes/postgres-schema.md (the resolution-vs-status write-up, npm run mistakes:index run after — same precedent as task 2's genesis-row bug, caught before shipping but still worth paying down once for the next reader).

Task 5 — Backup, export, deletion — the data-safety layer every system uses (2026-10-14)

What this run built. Migration 0222, applied to samo-dev only:

public.year_export_log — append-only (no UPDATE/DELETE policy for any role; RLS SELECT restricted to data_admin/dev). One row per (system, year) export actually taken, never a boolean flag — a flag could be set once and then the data could change under it; a log that a system may re-export any number of times is the only shape that cannot lose that.
year_export_recorded(system, year) — the gate. Plain boolean, SECURITY DEFINER, leaks nothing but existence. THE CONTRACT: any deletion/anonymisation RPC for ANY system, written by ANY later task, must call this first and raise if it returns false.
record_year_export(...) — the gated write path for a future admin "export now" button. Fails CLOSED for anyone without data_admin permission or dev role (verified live against samo-dev's pg_proc/ information_schema.role_table_grants during this task's own /scrutinize pass — table-level grants give authenticated SELECT only, anon nothing at all; both new functions carry the same PUBLIC-execute pattern current_user_has_permission itself already uses, which is safe here because both fail closed INSIDE the function body regardless of who is allowed to call them). Granted to nobody — a human decides who holds data_admin through ทีม SAMO → สิทธิ์, same as every other permission key.
Deliberately ships NO per-system anonymiser. VS's 24-month text-scrub (task 6), Shop's and หนังสือโครงการ's own retention (tasks 7/9) are each that task's own job, against a samo_year_be column some of those tables do not have yet — building one here, ahead of the column that makes it meaningful, would be deciding another task's policy from outside it and creating a second home for that rule the moment the real task ships (class 6). The contract is proven here with a pg_temp demo RPC that never touches a real table, not with a real anonymiser.

tools/year-export.mjs — one shared JSON+CSV exporter, plan-only by default, for pr_tickets, vs_tickets, shop_orders (+shop_order_items), projects (+project_documents+project_sign_requests), team_archive_nodes, team_archive_members. Reads through the SAME select shape each system's own admin screen already uses (select=*, or the exact ORDER_FIELDS/PROJECT_FIELDS nested literals from src/js/shop/api.js/ src/js/projects/api.js — year-export.test.js greps those files so a change there cannot silently drift from this tool). Prefers a system's own stored samo_year_be column when a later task has added one, falls back to deriving from the system's own timestamp column via 0219's samo_year_for_timestamp() when it has not — so the tool needs NO change when tasks 6/7/9 ship their own columns. --apply writes the files and records the export directly into year_export_log (NOT through record_year_export() — the Node tool runs via the Management API as the Postgres superuser, where auth.uid() is null, so a gate keyed on it would refuse the one caller meant to write this row; see the migration header). --drive uploads the written files to My Drive/IT Database/Archives/<year>/ via a new GAS action, uploadArchiveFile (appscript/prform.gs) — mirrors uploadShopFile/uploadTeamFile's allow-list pattern exactly, but deliberately does NOT call setSharing(ANYONE_WITH_LINK) the way those do, since an export can carry PDPA-covered VS text or a buyer's address. Exercised against REAL samo-dev data this run (plan-only and --apply both, including the nested shop/projects shapes — 7 orders/9 items, 33 projects/53 documents/18 sign requests — then cleaned the test log rows and scratch files back out); --drive was written but never called (no Drive credential in this environment).

server/supabase-backup.sh + .timer/.service/.env.example — whole-database pg_dump, modelled directly on server/vaultwarden/backup.sh's discipline (verify the copy via pg_restore --list, assert content not just exit 0, never prune until the new one verifies, exit non-zero so the timer shows FAILED). Written, never run — this environment has no SUPABASE_DB_URL and no access to the VM. The IPv6 question (SUPABASE_DB_URL's direct host is IPv6-only per skills/build-the-dev-database.md; whether the VM has IPv6 egress is unknown) is decided as a plan, not tested: try the direct host, and if it times out, switch to Supabase's own Session-mode pooler (IPv4 by design) — written up with the exact verification commands in skills/backup-and-export.md, not claimed as working.

Decisions made, and what was rejected:

A log table, not a column on team_terms — a system's export and a team's handover are unrelated events (a cautious ฝ่าย might export twice before a handover that never happens); only a per-attempt log can't lose that.
The Node tool writes year_export_log directly, bypassing record_year_export() — rejected making the tool call its own gated RPC, since the Management-API connection's null auth.uid() would make the RPC refuse the only caller meant to use it; same shape apply-migration.mjs already uses for schema_migrations.
No per-system anonymiser built here — rejected building even one concrete example against a real table (VS was the most fully-speced candidate in docs/YEAR-ROLLOVER.md), because VS's own samo_year_be column is task 6's to add; proving the CONTRACT against a pg_temp demo function instead keeps this task's migration from deciding task 6's policy or creating a second home for it.
Registry excludes vs_public_comments/vs_followers/vs_tags, project_files, shop_pickup_batches — no samo_year_be to key the first three by yet (task 6), project_files is read through Drive-backed GAS handlers rather than the PostgREST shape this tool mirrors (and the app's own PROJECT_FIELDS select does not nest it either), and shop_pickup_batches is operational state the design doc never names for per-year export. Documented in the registry's own comment, not silently omitted.

Caught by this task's own /scrutinize pass before it shipped, not reported by anyone: the grandchild-fetch loop (project_sign_requests under project_documents) never actually read the parentOf field its own registry entry set and its own comment claimed to use — it always fetched against the immediate container's ids regardless, which only LOOKED correct because a plain two-level nest's grandchild's parent always equals its immediate container anyway. Fixed by rewriting the fetch as one recursive function that reads node.parentOf at every level (fetchChildLevel), with a new test using a synthetic three-level entry whose grandchild deliberately points PAST its immediate container to prove the field is consulted, not decorative. Also tightened --year validation from "anything Number.isFinite accepts" (so 2569.5 or " 2569 " would pass) to a plain-integer regex — the looser check let the on-disk folder name (built from the raw string) diverge from what actually lands in year_export_log (coerced and ROUNDED on insert into the smallint column), a confusing silent mismatch for a typo. Also verified LIVE (not assumed) that record_year_export/year_export_recorded's table grants and RLS match the migration's own claims, and that handleUploadArchiveFile never calls setSharing the way its public siblings do.

WRITTEN, NOT APPLIED to production: migration 0222. Depends on 0219 (task 2) applying first, same ordering constraint as every other per-system migration in this queue — year_export_log itself has no such dependency, but tools/year-export.mjs's timestamp-derived fallback calls 0219's samo_year_for_timestamp().

No changelog entry — nothing here is user-visible yet (no admin UI calls tools/year-export.mjs or the new RPCs; that wiring is each later task's job when it builds its own system's export button).

Task 3 — PR Form dashboard per SAMO year, export, Drive per year (2026-10-14)

Written up here only — the code and migration shipped in an EARLIER run of this same session, in commits 3978eeb and b998c52, between task 2's resume and task 4; this run (the handoff step) found the work done but this required heading missing, which is why the runner's Done when: check kept reporting task 3 as todo after a real attempt. Nothing below was built or changed by the handoff step — it re-verified what already shipped and wrote the record the check was waiting for.

What shipped (commit 3978eeb, fixed by b998c52 after a self-run scrutinize pass, both already on this branch):

Migration 0220 — pr_tickets.samo_year_be smallint, filled by 0219's shared samo_year_be_default() trigger at INSERT time, one-time backfilled for the 311 existing rows from their submission timestamp (not "now"), never recomputed after write. Year is a filter, never an access boundary — RLS unchanged.
PR Staff Dashboard (src/js/pr-year.js + pr-staff.js) — defaults to the current SAMO year via the shared samo-year.js picker, so the 290 โพสต์เรียบร้อย (เสร็จสิ้น) tickets the owner named stop crowding the default view; a "ทุกปี" option still shows everything, with a small year badge per kanban card so a mixed view stays legible. Editing a ticket from a past year is locked behind an explicit "แก้ไขของปีก่อน" override — scrutinize caught (b998c52) that the first draft keyed the lock on the dashboard's <select> (isPastYearView) rather than the individual ticket, so switching the filter to "ทุกปี" unlocked editing on every past-year ticket at once; fixed with isPastYearTicket(ticketYear, currentYear) read from the ticket's own samo_year_be.
CSV export of the filtered view, through the repo's existing formula-safe CSV writer (grepped for, not reimplemented).
Drive: new PR uploads go to a per-year subfolder (appscript/prform.gs, NOT deployed — needs npm run deploy:gas); a dry-run-by-default tools/pr-organize-drive-by-year.mjs sorts the existing flat files into per-year folders via Drive moveTo, never trash-to-move (a trashed Drive file is still public).
Every reader of PR data was checked and marked explicitly: Discord notify, the public PR tracking page, and the GAS-quota analytics dashboard are all SAMO-year-agnostic on purpose (each says why, in a comment at the read site) — only the staff dashboard and the Drive layout are year-scoped.

Re-verified by this handoff step, not assumed: ran node tools/db-query.mjs tools/pr0220-year-filter.sql against samo-dev fresh — 23/23 PASS, confirmed → project: xibugtlsphcfuvstnxxh (samo-dev). Confirmed the Done-when's other two conditions independently: the grep for samo.year|samoYear|yearPicker|year-picker over src/js/pr*/src/js/admin* matches, npm test is 2716/2716, npm run build completes clean.

WRITTEN, NOT APPLIED to production: migration 0220 and everything it defines. Depends on 0219 (task 2) applying first — same ordering constraint as every other per-system migration in this queue.

STATE.md and docs/state/HANDOFF.md §22's row for this task were already updated by the commits above — unchanged by this step.

Task 4 — ทีม SAMO + จัดการทีม + permissions handover + Discord roles (2026-10-14)

What this run built. Migration 0224, applied to samo-dev only:

Closed a real authz bug in task 2's own 0219. start_team_term (the handover RPC) gated on current_user_has_permission('team'). Since migration 0110 (already live, predates this whole queue), team is a VIEW-only key that effective_team_permissions_for_email() hands to EVERY person found in team_members automatically — ~300 accounts on samo-dev, none of whom chose to hold it, none of whom can edit anything. Gating a full year-handover on that key meant any of those ~300 accounts could flip the current SAMO year by calling the public RPC directly (no UI needed). Regated to team_edit — the exact predicate publish_team_term already uses, confirmed by reading its live body first, not assumed. Found by re-reading 0219 against 0110's own migration comment, not reported by the owner.
Made the handover self-archiving. start_team_term now calls publish_team_term(outgoing_year) inline, in the same transaction, before closing the outgoing term — so a handover always captures whatever the live tree looked like at that exact moment, with no separate "remember to click เผยแพร่ปีนี้ in the right order" step. This is what makes the owner's "next year's team is prepared without touching this year's … published at the boundary" literally true: call start_team_term FIRST, edit the live tree for the incoming team AFTER — the only order that needs no manual publish step to get right. Editing the tree BEFORE a handover is still technically possible and would still misfile history exactly as before 0224 — this narrows the failure window, it does not add a block that makes the wrong order impossible (rejected a "last-editor" guard trigger and a parallel "draft tree" for the same reason: both are bigger, riskier changes than one night's budget affords, and the existing dev-role escape hatch already covers the one failure mode — "nobody can run the next handover" — that a new trigger would exist to prevent).
Confirmed, did not change, Discord role sync. Read discord_role_targets() (0184/0196/0197): it reads team_members/ team_nodes/discord_links only, zero references to team_terms, so it is "the current term" by construction — a handover that touches no tree row moves no Discord role, and one that does is picked up by the existing queue/trigger mechanism within minutes, same as any other tree edit. Pinned with a regression assertion in the proof (§C) rather than left as an unchecked claim, since a future edit threading team_terms into that function would silently break this invariant.
จัดการทีม per year — confirmed, did not rebuild, that get_public_team_years()/get_public_team_chart() (0104/0105/0153) are already the one shared registry every picker (ทีม SAMO's own pane, org-chart.js, samo-year.js) reads from; no drift found.

Proof tools/team0224-handover.sql, 14/14 on samo-dev; registered in tools/run-proofs.mjs. Covers: a VIEW-only team holder refused calling the RPC, paired against a team_edit holder being allowed for the identical call (deny+allow, so the original bug — which also correctly refused a total stranger — could not have passed a deny-only probe); the outgoing term's archive matching the live PUBLIC tree's own node/member counts (297/447 on samo-dev, not the naive 299/449 total — publish only archives is_public nodes); and the Discord decoupling regression guard. Re-ran tools/year0219-samo-year.sql afterward — still 23/23, so the splice did not regress task 2's own coverage.

Self-review. Ran /scrutinize on the task's own diff (git diff b998c52..HEAD) before closing: traced the permission-fix correctness against current_user_has_permission's live body (confirms master still folds into team_edit exactly as it did into team), the nested-RPC call for escalation/recursion/invariant risk (none — the inner call re-checks the same predicate with the same auth.uid(), cannot create a second is_current row, and this nest-a-definer-in-a-definer shape is already used elsewhere in the codebase), the proof's temporary-principal setup for PII leakage (none — only id-derived counts/booleans ever reach the printed output, same rollback discipline as year0219), the UI copy change in terms.js for bugs (none — purely informational, reads an already-loaded client value), and the documentation claims against the actual code (all verified, not assumed). Found one wording overclaim in the migration's own header ("the ONLY workflow") and fixed it before this block was written, in a follow-up commit — see git log --oneline b998c52..HEAD.

Decisions made, and what was rejected (full reasoning in supabase/migrations/0224_*.sql's header and docs/YEAR-ROLLOVER.md's "ทีม SAMO" correction block):

Regate on team_edit, not a new narrower "handover" permission — rejected a new key because team_edit already functions as root over the tree (0110: holding it lets you grant anyone, including yourself, anything up to team_edit itself), so a narrower gate would be a distinction with no enforceable difference.
Auto-archive by calling the EXISTING publish_team_term inline, not by duplicating its SQL — one body, one place a future bug gets fixed once.
No new "last team_edit holder" guard trigger, and no "draft tree" for preparing next year's roster ahead of time without touching the live one — both rejected as bigger and riskier than this task's remaining budget, with reasoning in the migration header (permission resolution has too many overlapping channels to re-derive correctly on every tree write; a draft tree would have to either duplicate every permission column or omit them, in which case it could not be "prepared" with real grants attached anyway).

WRITTEN, NOT APPLIED to production: migration 0224 and everything it redefines. Depends on 0219 already being applied first (task 2's row in docs/state/HANDOFF.md §22 — unchanged by this task).

Task 2 — The ONE SAMO year — foundation, admin control, runbook (2026-10-14)

RESUMED after a quota cut-off. WIP commit f9bb1b7 had already shipped migration 0219 (team_terms.started_at/ended_at, current_samo_year(), samo_year_for_timestamp(), samo_year_be_default() trigger body, start_team_term(year) atomic handover RPC), the proof tools/year0219-samo-year.sql (24 assertions, never yet run), the shared picker src/js/samo-year.js + its JS/SQL differential test, and the rewire of team/api.js's setCurrentTerm onto the new RPC. Left undone by the WIP: the proof had never been applied or run against anything; tools/run-proofs.mjs did not register it; skills/year-rollover.md did not exist. All three were the actual Done when: gate for this task.

What this run did, in order:

Applied 0219 to samo-dev and ran the proof — green, 23/23 (node tools/apply-migration.mjs supabase/migrations/0219_*.sql --dev then node tools/db-query.mjs tools/year0219-samo-year.sql).
Registered year0219-samo-year.sql in tools/run-proofs.mjs (it was a file on disk the runner had never been told to run — exactly the class-7 hazard run-proofs.mjs's own header warns about).
Wrote skills/year-rollover.md — the runbook: what a handover IS (not a re-publish), the pre-flight checklist (who loses the admin seat), the one command (start_team_term), what happens to every other system afterward, how to verify, and what to do if it goes wrong.
Ran /scrutinize on the full task-2 diff and found a real bug before it shipped anywhere: the team_terms row that was is_current when 0219 first ran has started_at = NULL for a structural reason (the column didn't exist yet). start_team_term's reopen path (coalesce(started_at, now())) cannot distinguish that NULL from "never started" — so closing that ONE row once, then later reopening it (a real "we handed over and regretted it" scenario), would silently relabel its true "open since before this system existed" meaning as "started just now", breaking samo_year_for_timestamp() for every backfill timestamp older than the reopen. Reproduced in a rolled-back probe against samo-dev before fixing it (confirmed NULL came back for a 2026-06-01 lookup after the repro). Fixed by stamping the closing UPDATE's started_at to -infinity the moment a NULL-started_at row closes — before any reopen can misread it. Extended the proof with §G (steps 45–48: fix proven RED first by rerunning it against the unfixed migration, then green after). Also narrowed samo_year_for_timestamp's grant from anon, authenticated to authenticated only (least privilege — nothing anon-triggered calls it). Write-up: docs/mistakes/postgres-schema.md ("Reopening the genesis team_terms row…").
npm test (2687/2687) and npm run build green throughout.

Decisions made, and what was rejected:

Reused the existing จัดการทีม UI as the one admin control, rather than building a new "SAMO year" admin screen — team/terms.js's existing "ตั้งเป็นปีปัจจุบัน" button already called setCurrentTerm; only its implementation changed (two non-atomic PATCHes → one RPC). Building a second control would have been the exact "hand-written list beside a shared constant" class 6 already warns about, for a control that already existed.
No new master-specific check in start_team_term — it gates on current_user_role() = any(array['vp_admin','dev']) or current_user_has_permission('team'), and current_user_has_permission already folds master in (0111). Verified by reading 0111's live body rather than assuming; adding a separate master branch would have duplicated a channel that already works and risked drifting from it later.
Did not touch samo_year_for_timestamp's is_current/ended_at NULL-handling branches even though the fix makes the ended_at is not null branch structurally unreachable going forward — left for defence in depth (a manually edited row, or a samo-dev reset that reintroduces a raw NULL) rather than deleting code that still describes a real, just rarer, case.
Did not add a CLI path for start_team_term separate from the จัดการทีม UI — the design doc's own reasoning (one control, never a second path that can drift) applies to the RPC's callers too.

WRITTEN, NOT APPLIED to production: all of migration 0219 (including the post-review fix) and the samo_year_be_default() trigger body it defines. Nothing yet ATTACHES that trigger to any table — tasks 3 (PR), 4 (VS), 5 (Shop) and 6 (หนังสือโครงการ) do that in their own reserved migrations (0220/0221/0222/0223) and must each run start_team_term's prerequisite (0219) on production FIRST, since their triggers call current_samo_year().

Task 1 — design doc (2026-10-14)

Claims to have read every system this queue names (PR, VS, Shop, หนังสือโครงการ, ทีม SAMO, เกี่ยวกับเรา, ระบบบ้าน, หน้าฝ่าย, Passport, Announcements, Accounts, Stats, Claude booking, Discord, Drive) end to end — docs/CONTEXT.md in full, docs/INVARIANTS.md in full, the relevant migrations (0104–0106 team terms/archive, study-year.js, passport/db/0006, appscript/prform.gs's folder layout) and modal-vs-consent.html's actual PDPA wording rather than assuming it — and written docs/YEAR-ROLLOVER.md (45 Decision: lines, 27 edge cases, a build-order table mapping every later task to its reserved migration number 0219–0229) plus docs/state/HANDOFF.md §22 (the per-task tracking table every later task must update its own row of, never another task's).

Core decision, defended: public.team_terms (existing, with is_current/archive machinery already built in 0104–0106) becomes the ONE SAMO-year registry every other system references — rather than inventing a new table, or promoting Passport's own samo_years (rejected: Passport's year/season answers a different, ฝ่ายกิจกรรม-decided question and lives in an isolated schema with no cross-schema FK precedent anywhere in this repo). Each operational table gets a nullable samo_year_be smallint, trigger-filled from a new current_samo_year() AT INSERT TIME and never recomputed later — mirroring projects.fiscal_year_be's existing override shape, but filled automatically rather than left null-by-default, specifically so the PR Staff Dashboard (the owner's own named example, 290 โพสต์เรียบร้อย tickets) gets a working year filter with no gap for new rows. ปีงบ (fiscal year, Oct-start) and ปีการศึกษา (academic year, Aug-start, study-year.js) are explicitly kept as SEPARATE calendars — not unified into "the SAMO year" — because each already has correct, independently-moving logic that predates this queue and conflating them would corrupt rows a university officer or a student already reads.

Self-review, before ending the task: ran scrutinize's method by hand against this doc (no sub-agent invocation; the skill resolved to prompt-only instructions, so I applied its trace/verify steps myself) and found — then FIXED in the doc, not left as a note — one real gap worth flagging loudly: the first draft gave หนังสือโครงการ's 42 existing rows a one-time timestamp-derived backfill for the new samo_year_be column but did NOT give the same backfill to PR's 311 / VS's 119 / Shop's 43 existing rows, even though the identical reasoning applies to all four ("no human has chosen a year for a pre-existing row yet, so deriving one from the timestamp overwrites nothing"). Left as originally written, every one of the 290 already-finished PR tickets the owner used as the motivating example would have rendered as "ก่อนเริ่มระบบปี" forever instead of being folded into a real past year — the feature would ship looking complete and solve nothing for the exact pile that was named. Fixed by adding the same backfill decision to PR, VS and Shop's sections. Three smaller fixes also applied: clarified that team_terms.started_at/ended_at are owned only by the NEW start_team_term() RPC (not publish_team_term, which is a repeatable snapshot action and would otherwise get called every re-publish); separated the PDPA retention SHAPE (anonymise, grounded in the consent notice's own wording) from the 24-month NUMBER (an invented default, labelled as such) and flagged that the consent modal itself never states a retention period, which is a pre-existing gap outside this doc's build order; and noted that Shop's samo_year_be is stamped from wall-clock current_samo_year(), not derived from placed_at, so a hand-entered backdated walk-in order can legitimately disagree with its own placed_at and needs the same admin-override affordance as every other table.

What is WRITTEN, NOT APPLIED: everything — this is design-only, task 1 of 11, and intentionally touches no supabase/migrations/ file and reserves no migration number of its own. npm test (2675/2675) and npm run build both green; the only non-doc change is registering the new file in docs/.vitepress/config.mjs's TOP_GROUPS (required by docs-site.test.js, which was red until that one-line addition).

Exact commands the owner runs next: none required from this task alone — read docs/YEAR-ROLLOVER.md once, then let tasks 2–11 proceed against it. If reviewing cold, start at docs/YEAR-ROLLOVER.md's ## Build order table and docs/state/HANDOFF.md §22's tracking table, in that order.

What would change my mind: if the owner would rather fold ปีงบ or ปีการศึกษา INTO one unified SAMO year instead of keeping three calendars — that is a bigger, riskier rewrite than this queue's remaining budget affords, and I chose the smaller, additive design on purpose; flag it in review rather than silently rebuilding if the owner disagrees.

⛔ Reviewed by the owner's session, 2026-10-13 — read docs/state/HANDOFF.md §20, not the block below, for what is true. Its "do this first" is CLOSED (0214 was already live on production). Its "nothing was skipped" was wrong: task 2 was cut off by the quota and the runner credited the half-done work (runner fixed). 0213 was rewritten to grant nothing — หน้าฝ่าย editors are chosen in ทีม SAMO.

▶ HANDOFF 2026-10-13 04:11 UTC (night agent, branch agent/2026-10-13)

1. Do this first. node tools/pass-anon-probe.mjs against production, before touching anything else on this branch. It is the ONE check this run could not do (no DB access) that decides whether migration 0214 below is closing a live critical hole or a tightening on an already-safe system — the private report explains why the static analysis alone can't tell the difference. Full reasoning: ~/samo-night/reports/2026-10-13-security-db.md Finding 1 / ## Verdict.

2. Status of the queue. All 6 tasks ran and the runner marked all 6 Status: done in ~/samo-night/NIGHT-TASKS.md — this was a clean, complete run (AGENT_UNRUN=0, AGENT_STOP=queue finished, AGENT_ASKS empty; nothing was skipped and nothing ended by asking a question). npm test — 2604/2604 green. npm run build — green. Working tree clean, everything below is already committed on this branch (see git log --oneline origin/main..HEAD for the six fix/feature commits plus whatever this handoff adds).

3. READY TO USE vs still a DESIGN.

Code is ready to review and merge, but nothing SQL-shaped has touched a database — migrations 0212, 0213 and 0214 are WRITTEN ONLY. Apply in that order, dev first: 0212 (ฝ่ายสโม project tags), 0213 (dept_page grants for the 6 new ฝ่าย), then — only after step 1 above — 0214 (passport lockdown ported into tracked history). Each has a proof script (tools/proj0212-samo-depts.mjs, tools/dept0213-team-samo-grant.mjs, tools/passport0214-lockdown-committed.sql) registered in tools/run-proofs.mjs but never run — "written, not applied" for all three, as the night-queue rules require. STATE.md's migration/proof-count lines were updated to match what's on disk, not what's been proved.
The nginx header fix (server/nginx-samo.conf) is a config change, not code or a migration — it does nothing until someone runs sudo cp server/nginx-samo.conf /etc/nginx/sites-available/default && sudo nginx -t && sudo systemctl reload nginx on the VM (skills/deploy-vm.md).
The 9 bug fixes from tasks 5–6 (admin: re-entry data loss, a chip-toggle race, a stacking delete listener; public+passport: six more, listed in their commit messages) are ordinary frontend/JS changes — ready to ship on the next normal deploy, no DB step needed. 5 PENDING changelog entries were added for the ones that affect an already-live feature.
Two security reports are DESIGN-level findings, not incidents: both ~/samo-night/reports/2026-10-13-security-{db,app}.md end ## Verdict with one thing fixed each (0214 written; nginx headers) and a short list of already-known, owner's-call items re-confirmed rather than re-raised. They live outside the repo on purpose — do not copy their content into anything under docs/.

4. What did not happen. Nothing — AGENT_UNRUN and AGENT_ASKS were both empty this run. All 6 queued tasks executed and the runner confirmed each Done when: check passed.

5. What needs a human decision.

Whether Finding 1 (step 1 above) was a live exposure. If pass-anon-probe.mjs reports the pre-hardening state, the report recommends treating the window since migration 0056 as a potential exposure period worth a Drive/audit-log-style sweep of passport.scans — a judgment call on how much to dig, not something this run can size without DB access.
Three already-known, low-severity items were re-confirmed open and left alone, each because touching them wasn't this run's call: the username→email lookup (owner already informed, memory open-privacy-username-lookup.md), the legacy passport admin/1234 speed-bump (accepted trade-off), and passport's per-ฝ่าย write-scoping gap (a real feature question, not a lockdown gap). I'd leave all three as-is unless the owner's priorities have shifted since those were last decided.
Task 2's dept_page inheritance decision (0213): inherited, not review-gated — defended in the Task 2 block below. Overturn only if the owner wants a staff-approval step added across all twelve ฝ่าย, which is a product decision bigger than this migration.
migration 0212's trigger checks WHO, not WHAT (app security report Finding 2) — left open as inert (every render path escapes the value) and not worth its own reserved migration number tonight; fold the allow-list check in next time 0212 is touched for something else.

6. What could not be verified, and why. No database access this run (by design — tools/db-query.mjs, apply-migration, .env.local all denied), so every claim about what 0212/0213/0214 will do once applied rests on reading the SQL, not on running it against dev or production. No Google/GAS credentials either, so the notifyProjectEmail content-hardening item and the GAS-side fileId ownership check mentioned in the app report are read-only findings, not reproduced. npm run handoff:check could not reach a verdict in this sandbox (no origin/agent/2026-10-13 remote to diff against, and this sandbox's memory path differs from ~/samo-night/memory/MEMORY.md named in the task preamble) — flagged rather than silently skipped, per CLAUDE.md; this looks like a standing gap in the night-agent workflow itself, worth the owner's attention independent of tonight's actual work.

2026-10-13 — Task 4: security review (deep) — the app, the servers, Apps Script

Claims to have: read every file in scope end to end (src/, server/*.mjs, server/nginx-samo.conf, appscript/prform.gs, passport/js/) and written ~/samo-night/reports/2026-10-13-security-app.md (outside the repo, per the queue's public-repo rule), ending ## Verdict. One real finding fixed, one informational finding left open, several already-known/already-ranked items re-confirmed still accurate rather than re-raised as new. Full reasoning is in the report; this block is the pointer + what changed on disk.

Fixed: server/nginx-samo.conf — no clickjacking/MIME-sniffing headers anywhere on the site. Added X-Frame-Options: SAMEORIGIN, Content-Security-Policy: frame-ancestors 'self', X-Content-Type-Options: nosniff, Referrer-Policy: strict-origin-when-cross-origin to every HTML-serving location (/admin/, /passport/, /docs/, the public catch-all /) — each repeated PER LOCATION, never once at server level, because add_header does not inherit into a location that already sets one of its own (every location above already sets Cache-Control), and a server-level copy would also have reached /vault/, which sets none of its own HERE and would have inherited it — stacking a second frame/XFO header on top of whatever Vaultwarden's own response already carries. That is the exact failure shape this same file's /vault/ block already documents for Cache-Control (two headers, browser honours the strictest, whole vault re-downloaded every load) — this is that lesson applied, not re-learned. ⛔ THIS IS A CONFIG FILE CHANGE, NOT A MIGRATION — it needs sudo cp server/nginx-samo.conf /etc/nginx/sites-available/default && sudo nginx -t && sudo systemctl reload nginx on the VM (skills/deploy-vm.md) before it does anything; nothing is served differently yet. No HSTS added — left for the owner to verify the KKU edge never serves this host over plain HTTP before adding it (getting that wrong locks users out for max-age with no undo).

Left open, informational, not fixed: migration 0212's projects_samo_depts_guard trigger checks WHO may touch samo_depts, not WHAT values land in it (the allow-list lives only in the RPC, set_project_samo_depts, which a direct PATCH from an already-authorized sender-desk account could bypass). Not fixed tonight because it is inert — every render path I found (including this same migration's OWN new render code) passes the value through escHtml(), so a smuggled garbage value cannot become a stored XSS payload, only a weird-looking tag. Not worth a reserved migration number (0215) in isolation; fold the value check into the trigger whenever 0212 is next touched for something else.

Re-confirmed, not re-raised as new (all three already tracked elsewhere, none actioned, none requiring action tonight): notifyProjectEmail's subject/body still caller-controlled within the domain allow-list (docs/NEXT.md, ranked options, needs a GAS redeploy this run can't make); passport's per-ฝ่าย WRITE scoping gap (admin-scope.js's own comment / Finding 4 of the companion DB report); the legacy passport admin/1234 door (accepted "speed bump, not a secret" trade-off).

npm test (2,579/2,579) and npm run build both green — the change touches no JS, so this was really about not having silently broken the conf's syntax (brace-balance checked by hand; no nginx -t available off the VM).

npm run handoff:check could not run to a verdict in this sandbox — pasting the actual failure rather than skipping silently, per CLAUDE.md's "a skip is NOT green." Two environment-specific crashes, neither caused by tonight's change: (1) it diffs against origin/agent/2026-10-13, which does not exist — this branch is correctly unpushed per the queue's own constraint, so the script's assumption (a tracking remote) does not hold for ANY night-agent branch, not just this run; git branch -a confirms no remotes/origin/agent/2026-10-13. (2) it then reads memory from ~/.claude/projects/-home-ubuntu-samo-agent/memory/MEMORY.md, which does not exist in this sandbox — the real memory index this run was told to read lives at ~/samo-night/memory/MEMORY.md (a different path, stated in this session's own system preamble). Neither task 1's nor task 2's block above mentions running this check either, so this looks like a standing gap in the night-agent workflow rather than something new tonight — worth the owner's attention before trusting a GREEN from this script on an unpushed night-agent branch at all.

2026-10-13 — Task 2: หน้าฝ่าย for every ฝ่าย, and the permission (0213)

Claims to have: grown DEPT_DEFS (src/data/depts.js) from 6 to all 12 top-level ฝ่าย ทีม SAMO's tree carries (measured on production, named in the task brief) — สำนักนายกฯ, กิจการภายใน, กิจการภายนอก, กิจการมหาวิทยาลัย, คุณภาพชีวิตและสิ่งแวดล้อม and รพ. ร่วมผลิต are new; two (--dept-office, --dept-hospital) got their own colour tokens in base.css, the other four reused tokens already sitting unused in base.css (--dept-internal/external/ university/quality). Converted the four disabled "เร็วๆ นี้" placeholder cards in tab-departments.html to real data-dept-open cards and added the two new ones — nothing else needed hand-editing: the grant picker (DEPT_PAGES in team-vocab.js), the /admin/ → หน้าฝ่าย editor's dropdown (dept-page-admin.js's editableDepts()) and the tools registry all derive from DEPT_DEFS, which is the whole point of that file existing (its own header comment). npm test and npm run build green.

Written, NOT applied/run: migration 0213 (supabase/migrations/0213_dept_page_grants_come_from_team_samo.sql) and tools/dept0213-team-samo-grant.mjs, registered in run-proofs.mjs. STATE.md's migration/proof-count facts updated to match.

Decision, defended — inherit, do not widen, and do not add a review gate. The brief asked me to decide from the code whether a dept_page set on a node is inherited by everyone posted under it (yes — node_effective_dept_pages()/effective_team_dept_pages_for_email(), 0177, walking up while inherit_permissions holds, same shape as every other scope dimension — vs_dept, project_seat, passport_scope, shop_source) and to narrow if that inheritance would (a) let someone edit a page they shouldn't, or (b) let a member publish without review. I did not narrow, because: (a) current_user_dept_page_scope() resolves to the caller's OWN tree posting only, and dept_content RLS checks dept = any(scope) on every read of a hidden row, insert, update and delete — there is no path from "posted under ฝ่ายกิจการภายใน" to touching ฝ่ายกิจการภายนอก's rows. The proof's §2b/§4/§5/§6 chain exists specifically to pin this: a synthetic leaf posted under the real ฝ่ายกิจการภายใน node resolves to exactly {internal} through the SAME function the sync job calls (not a hardcoded array), and the subject that scope is synced onto can edit the internal row and is refused on the external one. (b) There is no staff-review step for ANY of the six ฝ่าย this already runs for today (dept-page-admin.js's save() PATCHes live; the only gate is RLS, not an approval queue), and the one safeguard that exists — a NEW row is born visible = false until the ฝ่าย itself flips it on — is per-ROW and already identical across all twelve. Granting the other six ฝ่าย the exact mechanism the first six already have removes an inconsistency; it does not introduce a new risk to weigh. What would change my mind: if the owner wants a real staff-approval step before a ฝ่าย's page goes live, that is a product decision for all twelve ฝ่าย, not something to bolt onto only the six this migration covers — flag it in review rather than half-build it here.

Decision: the migration sets dept_page only where it is null (asserted in depts.test.js, "only fills a NULL… never overwrites"). The original six ฝ่าย may already carry a hand-set scope through the admin tree UI that is narrower or broader than "the whole top-level node" — 0177 lets dept_page live on ANY node, not just the root — and this migration has no way to tell "nobody set this yet" from "an admin deliberately chose a different node", so it only fills the gap the complaint was actually about.

Not done, by design: no change to dept-tint.js (the org-chart colour table) — it already resolves สำนักนายกฯ to the admin tint and leaves the other five of the new six unmatched (falls back to brand green), which its own header comment documents as NORMAL ("15 roots, 10 colours"). That table answers a different question (which EXISTING tree node, at any depth, gets which bar colour) from DEPT_DEFS.colorVar (which fixed colour THIS ฝ่าย's own page header uses) — extending one was not asked and was not needed to satisfy the Done-when check.

See the migration's own header comment for the full reasoning, and docs/DEPT-TOOLS.md §2 for why DEPT_DEFS has exactly one home.

2026-10-13 — Task 1: ฝ่ายสโม tags on หนังสือโครงการ (0212)

Claims to have: added projects.samo_depts text[], a column-guard trigger, set_project_samo_depts() RPC, a ฝ่าย tag editor (chips) on the detail header for the sender desk, read-only chips everywhere a project renders (card, list, detail, public mirror), and a "ฝ่าย" filter dropdown in both toolbars (AND- combined with the existing bucket/search/ปีงบ filters). npm test and npm run build green. Written, NOT applied/run — migration 0212 and tools/proj0212-samo-depts.mjs are on disk, untouched by anything with DB access this run.

Decision, defended: the column guard checks current_user_can_publish_project() (0114's existing "sender side" predicate — role vp_admin/dev OR the vpa seat), NOT a bare 'vpa' = any(current_user_project_seats()) check. The task brief said "checks the caller holds the vpa desk (or master)" — I read that as "whoever may act as the sender", and the raw seat check is NARROWER than that: 0111 is explicit that a dev-role account does NOT automatically hold master or any stored seat, so a bare seat check would silently refuse a dev account even though dev passes every OTHER sender-side gate in this table (insert, delete, is_public). The JS-side canManage the editor UI gates on is role === 'vp_admin' || role === 'dev' (inherited from the existing detail- header actions block) — reusing 0114's predicate is what keeps the DB and the UI agreeing, and the proof script's §3d subject (subj_dev: role=dev, no seat, no master permission) is there specifically to pin this. What would change my mind: if the owner wants dev excluded from tagging specifically (unlike every other sender-side action), that's a one-line narrowing of the trigger/RPC predicate back to the seat-only form — flag it in review, don't silently "fix" it.

Decision: stored tags are deduplicated and sorted alphabetically by the RPC (array_agg(distinct d order by d)) rather than preserving insertion order. The UI never reads order (chips render in VS_DEPTS's own order; the read-only pill list just lists what's present), so there was no reason to preserve caller-supplied order, and a deterministic stored order made the proof script's assertions exact-match instead of set-comparing.

Not done, by design: the "survives the module's URL/hash state" line in the brief — I checked applyHashRoute/applyCustomerHash and neither module puts filterKind/searchQ/filterFY in the hash either (only the open project/doc does), so filterDepts not surviving a hash deep-link matches the existing contract for every other toolbar filter. Making ONLY the new filter hash-persistent would be the inconsistent choice.

See the migration's own header comment for the rest of the design, and current_user_project_seats() (0111) for the master→vpa fold this predicate depends on.

2026-10-13 — Task 3: deep DB security review

⛔ Full write-up is PRIVATE, not here: ~/samo-night/reports/2026-10-13-security-db.md (outside the repo, per both-repos-are-public.md / docs-are-published.md — this file is under docs/, which is served at /docs, so a still-open finding's detail does not belong here). Read that report, not this entry, for what was actually found.

One-line summary of what happened, safe to say here: read every RLS policy / SECURITY DEFINER function / GRANT / trigger in supabase/migrations/ (through this branch's 0214) plus passport/db/*.sql, cross-checked against docs/mistakes/authz-rls.md + authz-grants.md in full so nothing already-fixed got re-reported. Wrote migration 0214 (not applied) and tools/passport0214-lockdown-committed.sql (registered in run-proofs.mjs, now 60 live proofs) addressing the one finding that needed a fix; STATE.md updated to match. Before applying 0214 or anything else on this branch, run node tools/pass-anon-probe.mjs against production first — the private report says why, and the answer changes how urgently the rest of the review should be treated.

Three already-known, already-documented, low-severity open items were reconfirmed still open on the latest migration state and intentionally not touched (one is the owner's call per existing guidance, two are real features rather than lockdown gaps) — named in the private report, not here. Everything else checked (this branch's own 0211–0213, every create table has matching RLS, no permanently-disabled trigger, a handful of previously- unreviewed migrations) came back clean.

Task 8 — ระบบบ้าน + ข้อมูลของฉัน: academic-year rollover, graduates, the next รุ่น (2026-10-18)

RESUMED after a quota cut-off (WIP 392017a).

The WIP commit (392017a) had left undone: it stopped right after building and testing the core mechanism — nothing in it was wrong, but it had not yet (a) checked whether the rollover design doc and HANDOFF still matched what it actually built, (b) swept src/js/house/ and src/js/me-page.js for a hardcoded MD49–MD54/49..54 literal that would block MD55, (c) reasoned through held rows / help requests / the สายรหัส audit explicitly rather than just leaving them untouched, (d) run /scrutinize, or (e) written this block. This session did all five, found one real polish gap (below), fixed it, and confirmed the rest of the WIP was already correct as built.

What the WIP already did (verified, not redone):

isGraduated(rec, now) in src/js/study-year.js — the exact same live ชั้นปี arithmetic as studyYearLabel, as a boolean (studyYear(rec, now) > 6). Re-exported through house/fields.js.
house/gaps.js's per-person worklists (no สาย / no ชื่อ-นามสกุล / no รหัส / no ชื่อเล่น / หายไปจากไฟล์) filter to active = students.filter(s => !isGraduated(s, now)), and the scope denominator (SCOPE_STUDENTS) was changed to match (active.length, not students.length) so the percentage never compares two different populations.
house/index.js: the นักศึกษา roster hides a graduated รุ่น by default (filteredStudents), with a "แสดงรุ่นที่จบแล้ว (N คน)" switch (houseShowGraduated, same module-scope-let-resets-on-page-load pattern as the pre-existing heldShowDone); the ปีการศึกษา bump card now shows "N คนอยู่ปี 6 ตอนนี้ — จะกลายเป็น จบแล้ว ถ้าเลื่อน" before the admin presses it.
tools/house-gaps.mjs now primes setAcademicYear() from public.get_academic_year() before calling computeGaps, so the CLI report and the admin pane read the same population — ran it against samo-dev live (not just unit tests) to confirm the new query doesn't error: node tools/house-gaps.mjs → → project: xibugtlsphcfuvstnxxh (samo-dev), printed a clean report (1 active student in samo-dev's current house data, so the sample is thin, but the code path executed end to end with no crash).
gaps.test.js — a new describe block (4 cases, one a CONTROL on an active รุ่น) pins setAcademicYear(2569) module-wide specifically so the fixtures don't start silently failing once the real clock's fallback ปีการศึกษา passes 2569 — the exact "a proof whose geometry runs out" trap .claude/rules/mistakes.md class 7 names. npm test: 171 files, 2971 tests, all green both before and after this session's changes.
A PENDING changelog entry in plain Thai.

Decision (confirmed, not re-made): no migration, no students.graduated_at column — contrary to docs/YEAR-ROLLOVER.md's own first-draft proposal. The design doc had proposed a stored flag "set by a yearly job." The WIP built the derived form instead and documented why in study-year.js's own header; I agreed with that call and corrected docs/YEAR-ROLLOVER.md's ## ระบบบ้าน section and the summary table (it was still describing the rejected column as the plan, which would have been exactly the kind of doc/code drift .claude/rules/mistakes.md warns about — a reader opening the doc fresh would have gone looking for a column that doesn't exist) and docs/state/HANDOFF.md §22 row 8 (still said "QUEUED," no migration number used). Rejected alternative, restated for the record: graduated_at needs its own re-derivation every time year_offset changes (a ลาพัก correction) or an admin corrects ปีการศึกษา backwards — a second thing to keep in step for no benefit, when studyYear already recomputes for free. What would change my mind: if ชั้นปี arithmetic ever needs a SQL-side gate (RLS, a trigger) — study-year.js's header already says there is deliberately no SQL twin today, and if that changes, a derived JS-only isGraduated would need a SQL-side twin or a differential test at that point, not before.

Decision: held rows and help requests are NOT time-filtered by graduation. An unresolved held row for a รุ่น that has since aged past ปี 6 stays actionable forever — closed only through 0217's follow_up remark (ติดต่อไม่ได้ / คาดว่าลาออกแล้ว / ลาออก / เลขนี้ไม่มีตัวตน), never by the clock. Rejected alternative: auto-close or hide a held row once its รุ่น ages out — rejected because a held row represents a real person ฝ่ายข้อมูล never finished placing, and "they'd have graduated by now" is a reason for a human to write ลาออก/เลขนี้ไม่มีตัวตน on it, not a reason to stop asking. help-diagnosis.js's coveredCohortLabels/houseCoversCohort already answer the adjacent question (is a freshly-typed รหัส's รุ่น one ระบบบ้าน currently tracks) from the same live studyYear, so a claim for a graduated รุ่น is already correctly diagnosed outside — no change needed there.

Decision: สายรหัส assignment is never filtered by graduation.gaps.js's auditSai still runs over occupants = [...students, ...held] unfiltered (confirmed by a WIP test: a graduated person still occupies their สาย in the audit). This matches the doc's existing "สาย/บ้าน is never re-run" rule — graduation is a roster-visibility question, not a สาย-correctness one.

Decision: MD55+ needs no code change — verified, not assumed. Grepped src/js/house/ and src/js/me-page.js for a literal MD49/MD5[0-4]/the range 49..54 driving a branch; every hit left is a comment or a test fixture. cohortFromStudentId's accepted window (study-year.js, 2540–2580 พ.ศ.) already covers MD55 (cohort_year 2570). /me's own house card (house/my-house.js) already renders studyYearLabel() directly, so a graduated person's own card already says "จบแล้ว" with zero changes from this task — confirmed by reading the file, not assumed from the name.

What this session added, beyond the WIP (one real gap found by tracing the UI end to end, not just reading the diff): the roster's empty state said "ไม่พบนักศึกษาที่ตรงกับตัวกรอง" (no match) whether the search typo'd a name or whether it correctly matched a real person who is simply hidden by the graduated switch — indistinguishable to the admin, who would read the second case as "this person was never in the system." src/js/house/index.js: factored the non-graduation half of filteredStudents's predicate into matchesTypedFilters(s, f), and on an actual empty result (only when a filter is set and the switch is off) check once whether any graduated row would have matched the SAME typed filters; if so, the empty row now reads "ไม่พบในรุ่นที่ยังเรียนอยู่ — คนที่ตรงอาจอยู่ในรุ่นที่จบแล้ว ลองเปิด 'แสดงรุ่นที่จบแล้ว'" instead. Costs one extra .some() pass, and only on the miss path.

/scrutinize run on git diff c5cf70f..HEAD (the whole of task 8, WIP + this session): traced isGraduated through every call site (gaps.js's active filter and scope text, index.js's roster filter/count badge/bump-card badge, tools/house-gaps.mjs's priming), confirmed the academic-year singleton (setAcademicYear/academicYear() in study-year.js) is primed once at pane load (house/api.js) and shared consistently by every one of those call sites with no second clock; confirmed gaps.test.js's module-wide setAcademicYear(2569) does not leak across test files (vitest's default per-file module isolation; full suite stayed green); confirmed the ผังตามสาย grid view (sai-grid.js via renderSaiGridPane) deliberately reads the unfiltered students array, not filteredStudents(), so a graduated person's สาย placement is still visible there — consistent with the "สาย is never re-run" rule, not a gap. The one finding (the empty-state hint) is fixed above; nothing else survived review.

Not touched, correctly out of scope: ทีม SAMO's own year-column drift (already fixed historically, per study-year.js's own header story) and the Passport/หน้าฝ่าย/Announcements rollover work — those are tasks 9–10's rows in docs/state/HANDOFF.md §22, not this one.

Commands the owner runs next: none required for this task — no migration, nothing to apply to any database, no deploy dependency beyond the normal bundle. git log --oneline c5cf70f..HEAD on agent/2026-10-18 for the full diff; review and merge like any other task on this branch. If the owner disagrees with the derived-vs-stored call, the revert is confined to study-year.js's isGraduated + its three call sites — no migration to roll back since none was written.

npm run handoff:check verdict — could not complete, same known crash as Task 1's §5 (2026-10-14): ENOENT reading ~/.claude/projects/-home-ubuntu-samo-agent/memory/MEMORY.md (that directory exists but is still empty; this session's real memory store is ~/samo-night/memory/, per this session's own system preamble — confirmed unchanged from the prior write-up, not re-diagnosed). Also reported origin/agent/2026-10-18 as unknown (this branch has never been pushed — expected, this agent cannot push). Ran with --local too; same crash. Per Task 1's own note, fixing the memory-path assumption in tools/handoff-check.mjs is a tooling question outside this task's scope (it would touch every other task's handoff step too) — left alone again. Substituted direct checks: npm test (171 files / 2971 tests green, both before and after this task's changes), npm run build (clean), git status (clean after each commit), and a live run of node tools/house-gaps.mjs against samo-dev (confirmed by its own → project: … (samo-dev) line) to prove the new SQL query the WIP added actually executes.

Task 9 — SAMO Shop: orders across SAMO years, plus the customer-flow worry (2026-10-18)

RESUMED after a quota cut-off. The run that wrote everything below through "npm run handoff:check verdict" (commit 8f6ee17) was cut off by the quota immediately after writing that verdict — this heading already existed, npm test/npm run build already passed, and parts A and B below were, on inspection, actually complete (migration 0230 31/31 on samo-dev, admin year picker wired on both tabs, the cross-tab cart fix with red-then-green tests). What the cut-off actually left undone, found by re-running the verification this resumption was told not to skip:

npm test was RED on resume: docs/state/HANDOFF.md §22 row 9 named shop/state.js (relative to src/js/shop/, not the repo root) — state-handoff.test.js's "names no file that is not there" check failed. One-line path fix (2acb60c).
/scrutinize on this task's own diff (41fbf2c^..HEAD) found a real bug 0230 introduced and the WIP never caught: the "ต้องจัดการ" tiles (ยังไม่ส่งสลิป / สลิปไม่ถูกต้อง / มีปัญหา) and "รายรับสะสม" counted across every SAMO year while the view each tile opens into (the orders table, the ยอดขาย tab) was year-filtered to the current year by default — so a pending/review order left over from a previous team (exactly the "ค้างจากปีก่อน" case this task exists to handle) could inflate a tile's count with no way to reach it by clicking. Fixed: scoped/revenue in renderStats() (src/js/shop/admin.js) now read yearFilteredOrders(); queue (the slip-review count) stays on state.orders unchanged on purpose, because its destination (ตรวจสลิป) is deliberately never year-filtered. Write-up: docs/mistakes/app-state.md ("SAMO Shop admin: the 'ต้องจัดการ' tile said one number, clicking it showed fewer rows").
Added direct unit coverage for orderMatchesYearFilter itself (src/js/shop/data.test.js) — it had none; its PR mirror ticketMatchesYearFilter did.
Everything else below (parts A and B, the proof, the admin UI, the cart fix) was verified as-is, not rebuilt: re-ran tools/shop0230-samo-year.sql live against samo-dev (31/31 again) and the full npm test/npm run build after each fix above.

Two unrelated pieces of work, both inside this task's own scope: (A) give shop_orders a SAMO year, same shape as PR/VS/โครงการ; (B) walk the customer checkout flow end to end for the owner's named worry and fix whatever actually breaks.

A. `shop_orders.samo_year_be` (0230)

Built docs/YEAR-ROLLOVER.md § SAMO Shop (never built before tonight):

shop_orders.samo_year_be smallint, stamped at INSERT by 0219's shared samo_year_be_default() trigger — copied 0220's (PR) shape exactly, with one difference explained in the migration's own header: the backfill reads placed_at, not created_at/timestamp, because shop_orders has no created_at at all (STATE.md, measured) and place_shop_order() sets placed_at in the same INSERT that creates the row.
Decision, confirmed against the design doc, not re-litigated: unpaid/in-review orders keep their ORIGINAL year across a handover — this falls out of the stamp-once-at-insert rule for free (nothing re-stamps on UPDATE), proven directly in the proof (§C2: an order stamped under a sentinel term stays stamped that term after the NEXT handover moves current_samo_year() on).
Decision: shop_order_totals() (0206 — the per-order Discord ping's totals line) IS year-scoped, to the current year only. Rejected alternative: leave it unscoped (all-time) — rejected because it is an OPERATIONAL snapshot ("how is the shop doing right now"), and left unscoped it would, the day after every future handover, ping Discord with a number inflated by every order every PAST team ever took — the exact PR complaint ("the next samoyear … it'll be a mess", 0220's own header) one system over. Added a defensive fallback after my own /scrutinize pass caught it (below): if current_samo_year() is ever NULL (no is_current row — should not happen once a team exists, but the function must not go near-silent the one time it does), the WHERE clause falls back to counting EVERYTHING, matching the ORIGINAL 0206 behaviour rather than reporting almost nothing.
Decision, unchanged from design: shop_products stays un-scoped — a product is inventory, not a transaction.
Admin UI: the orders table AND the ยอดขาย tab both got the shared samo-year.js picker (two <select>s, shopAdminOrdersYearFilter / shopSalesYearFilter, kept in sync by one setOrdersYear() in admin.js), defaulting to the current year. ONE predicate — orderMatchesYearFilter in src/js/shop/data.js — decides whether an order matches the picked year for BOTH tabs, so they can never disagree on what "2569" means (class 6: a hand-written list beside a shared constant). An order whose year the backfill could not resolve (null) always matches, same "unresolvable ≠ hidden" rule pr-year.js's ticketMatchesYearFilter already uses.
tools/year-export.mjs's REGISTRY.shop_orders already had yearColumn: 'samo_year_be' written in ahead of this column existing (task 5, 2026-10-14) — nothing to add there; it starts reading the real column automatically now that it exists.
OWED, not built: an explicit "correct this order's year" control in the admin order detail modal (same affordance fiscal_year_be gets on a โครงการ). The column is admin-overridable at the database level already (an UPDATE is never re-stamped — proven in the proof); there is just no button yet.

Proof tools/shop0230-samo-year.sql, 31/31 on samo-dev; registered in tools/run-proofs.mjs. Covers: §0 the column/index/trigger exist; §A/§B insert-time stamping + an explicit year surviving the trigger; §C/§C2 the backfill expression across a REAL two-step handover (sentinel years 2695/2696, backdated started_at so the two handovers land at genuinely different instants in one frozen-now() transaction) including an UNPAID order staying on its original year; §D RLS unchanged (buyer owns their own row regardless of year, a stranger is denied, admin sees every year); §E/§F shop_order_totals()'s current-year scoping AND its null-fallback, both by SNAPSHOT DELTA against shop_order_totals() itself — never an absolute count, so the proof holds regardless of how many real orders already exist on whatever database runs it (§F's first draft used a hardcoded expected delta and failed loudly against samo-dev's own pre-existing rows; fixed to recompute the expected value from the live table instead of guessing a constant). Insert path throughout: shop_orders_insert_admin (0035) as a role='dev' principal (satisfies BOTH current_user_is_shop_admin() and start_team_term's vp_admin/dev gate, same shape pr0220's principal uses) — buyers have had no direct INSERT on shop_orders since 0199.

B. The customer-flow walk

Traced the owner's named worry — "login ด้วย username password แล้วซื้อแบบนี้ กดออกไปหน้านี้แล้วมีปัญหา" (sign in, add to cart, navigate away, come back, something's wrong) — through the actual code, not just the shop files: cart persistence (shop/state.js), the router (main.js's navigateTo/ pathToTab/the shown.bs.tab handler), auth session handling (auth.js's onAuthStateChange), and checkout.js's own prefill/retry logic.

Found nothing wrong with the "navigate away" part itself. Every in-app destination the worry names — the shop tab, /me, the home banner's shop slide (departments.js's data-dept-tool-tab click-intercept) — routes with history.pushState + Bootstrap Tab.show(). Nothing on any of those paths calls location.reload(), so the cart (localStorage) and the signed-in session (supabase-js's own persisted session + auth.js's currentUser) both survive automatically, same as any SPA tab switch. checkout.js already has extensive, DELIBERATE handling for the related "the page re-renders under me" cases — applyBuyerPrefill's two rules (overwrite on account switch, fill-only-if-empty within one account), the placing lock against double-submit when SIGNED_IN re-fires on tab visibility, and findMyOrderBySlip-based retry so a lost response doesn't double-charge. None of that needed a change.

Found one real bug, in shop/state.js, unrelated to navigation mechanics: the cart is loaded into memory ONCE per browser tab and every mutation persists the WHOLE array, overwriting — not merging — whatever is in localStorage right now. Two tabs open on the shop (a product link opened in a new tab, a long-press "open in new tab", a duplicated tab) each hold their own stale copy; whichever tab writes NEXT silently drops whatever the OTHER tab had added, with no error and no toast. This is exactly the "another tab" half of the owner's own phrasing. Fix: a windowstorage-event listener (fires in every OTHER tab, never the one that wrote) reloads the in-memory cart before the next mutation can clobber it; also handles key === null (a future localStorage.clear()) since treating that as "ignore" would let a stale tab's next write silently undo a real clear — nothing calls clear() today, but the guard is free. Verified red-then-green (src/js/shop/state.test.js, two module instances sharing one fake localStorage): reverting the fix reproduces the exact loss. Write-up: docs/mistakes/app-state.md (new entry, "SAMO Shop: a product added to the cart in one browser tab could vanish…").

OWED, not run: a live-browser walk of the rest of the flow — the typed buyer fields and a picked-but-not-yet-uploaded slip file surviving a navigate-away-and-back mid-checkout — written at tools/browser/shop-checkout-navigate-away.mjs (same CDP-over-WebSocket pattern as shop-admin-tour.mjs) but NEVER RUN: this sandbox has no Chrome/Chromium binary and no network to install one (which google-chrome/chromium: nothing; npx playwright install webkit: EROFS on the npm cache — no network). The code trace above is strong (cart/session state is architecturally reload-proof here), but it is a trace, not a browser run; the script is the next thing to run on a machine that has Chrome.

/scrutinize pass on this task's own diff (git log --oneline e9af2fa..HEAD) found two real gaps, both fixed before this write-up: (1) shop_order_totals()'s current-year scoping had no fallback for current_samo_year() itself being NULL — fixed (§ A above) and proof extended (§F); (2) the storage listener did not treat key === null (localStorage.clear()) as a reason to reload — fixed and tested. Both caught by tracing inputs the happy-path proof/test did not try, exactly the discipline .claude/rules/mistakes.md class 7 asks for.

Commands the owner runs next:

Review this branch (agent/2026-10-18) and merge like any other task.
Apply 0219 to production first if not already (task 2's row), then node tools/apply-migration.mjs supabase/migrations/0230_shop_orders_get_a_samo_year.sql, then node tools/db-query.mjs tools/shop0230-samo-year.sql to prove it there too.
Deploy the frontend bundle (ships the year picker on both shop admin tabs
- the cross-tab cart fix).
Optionally, on a machine with Chrome: node tools/browser/shop-checkout-navigate-away.mjs against npm run dev to get the live-browser confirmation this sandbox could not produce.
Decide whether the "correct this order's year" admin control (§A, OWED) is worth building now or later — nothing depends on it.

npm run handoff:check verdict — same known crash as Tasks 1 and 8, re-confirmed on resume: ENOENT reading ~/.claude/projects/-home-ubuntu-samo-agent/memory/MEMORY.md (confirmed unchanged, not re-diagnosed; this session's real memory store is ~/samo-night/memory/). Ran with --local too; same crash, plus origin/agent/2026-10-18 reported unknown (expected — this agent cannot push). Substituted direct checks: npm test (172 files / 2977 tests green, after every change in both the cut-off run and this resumption — 2974 before the resumption's +3 orderMatchesYearFilter tests), npm run build (clean, both entries), git status (clean after each commit), and tools/shop0230-samo-year.sql run live against samo-dev (31/31 both before and after the resumption's fixes, → project: xibugtlsphcfuvstnxxh (samo-dev) — the resumption's fixes were frontend-only, so this proof did not need to change).

Task 10 — Passport, หน้าฝ่าย, announcements, stats retention, accounts (2026-10-18)

RESUMED after a quota cut-off (WIP 392017a gave the window back to a Claude booking; 7aa1f67 continued it and was itself cut off by the quota — two WIP commits, neither followed by this task's own write-up or a /scrutinize pass, which is exactly the gap tasks 11 and 12 both flagged and is what this session closes).

Point-by-point against the brief — what the WIP already did vs. what this session finished:

Stats (migration 0231, required). ✅ Already done by the WIP, verified not redone: analytics_daily_rollup + claude_usage_weekly_rollup, prune_analytics() rewritten to roll up a day in the SAME transaction it deletes it, prune_claude_usage_samples(weeks=8) added new, analytics_overview() rewritten so visitors_by_day/top_paths prefer the rollup for a pruned day and the raw table for a live one — proved by tools/stats0231-retention.sql, which explicitly asserts analytics_overview() survives a prune (steps 20/30). Re-ran live against samo-dev this session: 31/31, unchanged. notify_log's existing prune_notify_log (0055) is scheduled alongside the other two in the same VM timer script, not re-migrated. project_notifications deliberately gets NO prune (age-AND-read only, per the brief) — confirmed by reading server/stats-retention.sh, which calls exactly three functions and none of them touch project_notifications.
pg_cron vs. a VM timer — decided, not left open. pg_cron is NOT installed on this project (confirmed, STATE.md) and enabling it is a one-click Database→Extensions action only the owner can take; this agent has no production credential to take it even if it wanted to. WIP wrote server/stats-retention.{sh,service,timer,env.example} (same pattern as the existing server/supabase-backup.*, same SUPABASE_DB_URL reused, not a new credential) — WRITTEN, NEVER INSTALLED, same as every other VM asset this queue produces (no VM access from this sandbox). Timer uses OnCalendar=Sun *-*-* 04:40:00 (wall-clock, not OnBootSec/ OnUnitActiveSec — the exact class-7 trap .claude/rules/mistakes.md names) offset 40 minutes from the nightly backup timer so the two don't compete for the same DB connection window. If the owner prefers pg_cron instead, the migration's own header says the swap is one cron.schedule call per function, nothing here needs rewriting first.
Revision-pass fix, found AFTER the WIP, before this task's own write-up: 0231's prune_analytics() cutoff was NOT day-aligned. A WEEKLY timer with a non-day-aligned cutoff silently splits a calendar day across two runs — the first run rolls up and deletes the early hours, the second run recomputes the same day from only the surviving late hours and on conflict do update overwrites (not adds to) the first run's count, permanently losing the first half. Reproduced live on samo-dev (20 events before a simulated cutoff, 4 after, same day — first prune rolled up 20, second overwrote it to 4), fixed in migration 0233 (date_trunc('day', ...) on the cutoff, so a day is only captured once it is ENTIRELY before cutoff). Write-up: docs/mistakes/postgres-schema.md. Proof tools/stats0233-no-split-day.sql re-run live this session: 7/7. This was credited to "revision-pass work" in STATE.md/HANDOFF rather than folded silently into 0231, on purpose — it is a real bug in migration 0231's own design, not a cosmetic follow-up, and the queue's own rule is ADD, never silently retype a prior migration once it may have been applied anywhere.
Passport (0232). ✅ Already done by the WIP: passport.samo_years. team_term_year (nullable, no FK — matches the deliberate public/passport schema isolation; set by hand via the admin startNewYear() prompt in passport/js/admin-page.js, read back in the years list). The "never a gap between two years/seasons" invariant was NOT touched — confirmed by reading startNewYear()'s own open-before-close shape (admin-page.js:1518-1565), which already matched the invariant before this queue started; nothing here needed to change it. Leaderboard-per-year and past-year browsing were ALSO already live before this task (student dashboard's lb-year-select, admin's #lb-year, fl-year-select) — confirmed by grep, not rebuilt. Re-ran tools/passport0232-bridge- dept-editor-accounts.sql live this session: 22/22.
หน้าฝ่าย. ✅ Already done by the WIP: dept_content_editor_info(p_dept), gated with the SAME predicate dept_content's own RLS uses (current_user_dept_page_scope()), wired into src/js/dept-page-admin.js to render "แก้ไขล่าสุดโดย … เมื่อ …" under the ฝ่าย picker. UI-only, no year column, no version-history table — matches the design doc's explicit rejection of versioning (a ฝ่าย page is a living document, not a ticket).
Announcements. ✅ Already done by the WIP: reuses the existing status CHECK values (approved/archived), no new column — เก็บเข้าคลัง/ เผยแพร่อีกครั้ง buttons on the manage pane, a status filter (เผยแพร่/เก็บเข้าคลัง/ทั้งหมด), and the public feed confirmed (by reading loadAnnouncements's default statusFilter = 'approved' and its only caller on the public page) to already filter to approved-only — the pre-existing bug the design doc flagged as "verify, don't silently fix" turned out to not exist. Task 11 (not this task) found and fixed the one real announcements bug: editing an archived post silently republished it (nextAnnouncementStatus() now preserves the row's own status across an edit) — noted here for completeness, not reclaimed as this task's work.
Accounts. ✅ Already done by the WIP: account_dashboard(p_samo_year_be default null) — the old zero-arg signature was dropped first (two overloads would make PostgREST's no-arg RPC call ambiguous), the new one adds PR/VS/Shop/Projects activity counts optionally scoped to a year, master gate unchanged. Graduates/departing-staff account closure stays a PERSON decision, never a year one — confirmed by reading ## Accounts in docs/YEAR-ROLLOVER.md, which this task did NOT touch (no new deletion path was built). Default is "ทุกปี" (unscoped), not the current year — deliberate, reasoned in HANDOFF §22's per-decision list, not revisited here.
Claude booking. No code owed beyond the sample-pruning covered under Stats above — claude_bookings/claude_settings are a weekly operational cycle, not year-scoped (confirmed by reading ## Claude booking in docs/YEAR-ROLLOVER.md); no migration number was reserved for it and none was needed.

What THIS session actually did (the part the two WIP commits and tasks 11/12 left genuinely undone):

Wrote this block — docs/state/night-agent.md had no ## Task 10 heading at all; tasks 11 and 12 both read and reviewed task 10's work but neither wrote its own-task narrative, which is what the queue's Done when: check for this task actually greps for.
Fixed a real, mechanically-detected staleness bug: STATE.md said "67 of 72 LIVE PROOFS" but tools/run-proofs.mjs now registers 73 (the previous run's sweep-up commit 0ea0fcc added stats0233-no-split-day.sql to the registry without updating this count) — npm test was RED on state-handoff.test.js's "its live-proof count matches what npm run proofs actually runs" assertion before this fix. Corrected to "67 of 73" and named stats0233-no-split-day alongside the other samo-dev-only proofs in that sentence. This is exactly the "prose outlives the predicate" class (.claude/rules/mistakes.md class 6) — a number with ONE home that drifted the moment a sibling file changed next to it.
Re-verified all three of this task's proofs live against samo-dev (not trusting the counts already recorded by tasks 11/12): stats0231- retention 31/31, stats0233-no-split-day 7/7, passport0232-bridge- dept-editor-accounts 22/22 — all green, → project: xibugtlsphcfuvstnxxh (samo-dev) confirmed in each run's output.
Confirmed docs/mistakes/INDEX.md is already up to date (npm run mistakes:index → "up to date (446 entries across 10 files)") and HANDOFF §22 row 10 was already corrected by task 12 (DONE, with the apply-in-order checklist) — neither needed a further edit from this task.

Decision, restated for the record (made by the WIP, confirmed correct by this session, not re-litigated): the whole brief was built as THREE small, independent additions — a stats-retention scheduling gap, a Passport bridge column, and two read-only UI/RPC conveniences — rather than one bigger "year-rollover for everything else" feature. This matches every other system in this queue (0219's own shape: additive columns + functions, no behavioural change until the frontend reads them) and the design doc's own explicit rejections (no dept_content versioning, no announcements year column, no Passport/team_terms merge). What would change this: if the owner wants real version history on หน้าฝ่าย pages, or a scheduled (not manual) Passport↔team_term bridge, those are both bigger features this queue's budget deliberately did not build — flagged, not silently expanded.

npm test: 173 files / 2982 tests, all green (the one failure this session found — the proof-count mismatch above — is fixed, not worked around). npm run build: clean, both entries (public/admin + Passport). git status: clean after this task's commit.

npm run handoff:check verdict: same known crash as every prior task this queue (ENOENT reading ~/.claude/projects/-home-ubuntu-samo-agent/ memory/MEMORY.md — this session's real memory store is ~/samo-night/ memory/ — and origin/agent/2026-10-18 unknown, since this agent cannot push). Not re-diagnosed; already documented by Tasks 1/8/9/11. Substituted direct checks: npm test, npm run build, git status, and the three migration proofs re-run live against samo-dev, all shown above.

Commands the owner runs next: unchanged from HANDOFF §22's row 10 and the apply-in-order checklist above it (task 12's work) — apply 0230 before 0231/0232 (account_dashboard()'s rewrite reads shop_orders.samo_year_be), then 0231, then 0233 (MUST follow 0231 — it redefines prune_analytics()), then 0232; install the VM timer or enable pg_cron; deploy the bundle; click through the browser-verification table. Nothing in this resumption changed any of those commands — it closed a documentation gap and a stale count, not new schema or new UI.

Task 11 — Scrutinize + bug scan: tasks 8–10, and the owner's work since 2026-10-14 (2026-10-18)

Scope, per the queue's own brief: run scrutinize over this branch's own diff (tasks 8–10) AND over the owner's session work on main since 2026-10-14 (shop admin, home banner + tool icons + /me, year-rollover 0225–0228 + team/terms.js), then a bug scan of the whole app focused on what the year work touched and the owner's named worries: login cache for both sign-in kinds, switching accounts in one browser, the shop customer flow. Fix every real finding, write it up, 0233 for SQL. Full report: the 2026-10-18 review note (kept on the VM checkout under agent-notes, not in git) (that directory is excluded from git by .git/info/exclude — on disk, not committed, same as the 2026-10-13 bug-review files were before they got force-added; left as-is since the task's own Done when: only checks the file exists).

Task 10 was reviewed too, and it needed it most — its two commits are tagged WIP/"cut off by the quota" and had never been through a /scrutinize pass of their own, unlike tasks 8 and 9 (both of which already show a resumed/fixed pass in their own blocks above). Reading 0231/0232 in full and re-running their proofs LIVE against samo-dev (not trusting the counts already recorded in STATE.md) found them solid: stats0231-retention 31/31, passport0232-bridge-dept-editor-accounts 22/22, shop0230-samo-year 31/31 (re-checked for completeness, task 9's own). Every new SECURITY DEFINER function fails closed and anon is explicitly revoked, not just public. Tasks 8 and 9's prior fixes also held up under a fresh trace — isGraduated() has one home with no drift between gaps.js's denominator and house/index.js's roster filter, and the shop admin tile/year-filter fix (8552b4b) reads yearFilteredOrders() exactly where its own comment says it must.

One real bug found and fixed, in task 10's announcements-archive work: 0232's sibling feature added เก็บเข้าคลัง/เผยแพร่อีกครั้ง for ประกาศ and explicitly wired admin-main.js's enterCreator() / tryCreatorDeepLink() to resolve an archived post into the editor — but publishAnnouncement() still hardcoded status: 'approved' on every save (written before archiving existed), so editing an archived post's text — even a typo fix, no intent to republish — silently put it back on the public site. Fixed by extracting the decision into nextAnnouncementStatus(beforeRow, isEditing): new posts are always 'approved', edits preserve whatever the row already had. Tested (src/js/announcement-status.test.js, since publishAnnouncement itself is too DOM-heavy to unit test directly) and written up in docs/mistakes/app-state.md.

The owner's work (shop admin, home//me, terms.js) was delegated to a background general-purpose agent with the same "trace the real call path, don't trust the diff" brief this skill always uses, rather than re-walked by hand — it is already-shipped, already-reviewed code (commit 466451b alone logged six independently-found defects with tests) and re-deriving every predicate by hand a second time was lower value than spending that effort on task 10, which had never been looked at. It came back with one cosmetic finding: departments.js's modified-click allow-list named a[href][data-dept-tool-tab], but data-dept-tool-tab (tool-card.js) is only ever emitted on a <button>, which has no href — so that clause can never match. No behavior change (buttons were already excluded correctly by the surrounding code), so no docs/mistakes/ entry — there is no bug shape here to warn a future session about, only a dead selector removed and the comment reworded to say why.

Login cache for both sign-in kinds, and switching accounts in one browser — checked by hand, not delegated (security-sensitive; docs/mistakes/supabase-client.md read first, per CLAUDE.md). auth.js's buildCurrentUser treats Google and username/password symmetrically (method comes from auth.users.app_metadata.provider first, the stored column only as fallback — the 0211 fix) and reruns on every onAuthStateChange fire including the 25-minute TOKEN_REFRESHED, so a permission change reaches an open tab without a full sign-out. account-switch.js's fast-switch path already carries fixes for the two races this exact feature paid for before (the outgoing-token-capture race, the iPad Safari setSession wedge); the cross-tab case is supabase-js's own BroadcastChannel, confirmed present and wired in the installed auth-js version for persistSession: true — no app code needed, and none was missing. No new finding in either file. The shop customer-flow worry was task 9's own (the cross-tab cart storage listener, already fixed and tested there) — re-verified by trace, not re-fixed.

0233 was reserved and left unused — this task needed no SQL of its own; all three migrations it reviewed (0230/0231/0232) belonged to tasks 9/10.

npm test: 173 files / 2981 tests before this task's own change, 2982 after (the 4 new announcement-status.test.js cases plus the mistakes-index rebuild). npm run build: clean, both entries (public/admin + Passport). git status: clean after this task's commit.

npm run handoff:check verdict: same known crash as every prior task this queue — fatal: ambiguous argument 'origin/agent/2026-10-18..HEAD' (this agent cannot push, so the remote branch does not exist) followed by ENOENT reading ~/.claude/projects/-home-ubuntu-samo-agent/memory/ MEMORY.md (this session's real memory store is ~/samo-night/memory/). Not re-diagnosed — already documented by Tasks 1/8/9. Substituted direct checks (same shape Tasks 8/9 used): npm test, npm run build, git status, and the three migration proofs re-run live against samo-dev with → project: xibugtlsphcfuvstnxxh (samo-dev) confirmed in each run's output.

Commands the owner runs next:

Review this branch (agent/2026-10-18) — tasks 8–11 are now all DONE on it, nothing applied to production.
Read the 2026-10-18 review note (kept on the VM checkout under agent-notes, not in git) (on disk, not in git — see the scope note above) for the full trace behind every finding.
Task 10 never got its own /scrutinize write-up or HANDOFF row-10 update (its commits are WIP/cut-off) — task 12 (handoff checklist) should close that, not skip it because this task's review covered the code.
Nothing from this task needs applying — no schema change, and the two fixes are already committed on this branch.

Task 13 — review leftovers (2026-10-20)

Written by the OWNER SESSION, not the agent. The agent's run committed all four parts (13 (1/4) … 13 (3/4) and the sweep-up commit) but hit Reached max turns (200) before writing this block, so the runner scored it "not passed". The work was reviewed, merged to main and deployed on 2026-10-20; this block closes the task so the next run does not redo it.

What it did: cherry-picked wip/discord-review-fixes and fixed its two red tests to the restructured loop; the popup qty / colour cap; the cart's addItem stock cap; the บอท Discord poll no longer clearing a save error; csvGuard/csvUnguard round-trip every input; the nginx /img/ cache key.

What the review changed on top (all on main): the popup cap regained cart.js's 99 ceiling; a poll's own load error now clears; a settings read failing mid-pass aborts the pass once instead of reporting every change as refused (test red with the old catch); a pause still posts what was written; nicknames off stops a rename run. Not applied: the nginx line is in the repo only — install by hand (sudo nginx -t && sudo systemctl reload nginx after copying the location change), then check X-Img-Cache: HIT with and without ?x=1. Remaining gaps: HANDOFF §22 "Still OWED".

Task 14 — Make the proofs trustworthy: samo-dev fidelity and the two red proofs (2026-10-20)

RESUMED after a quota cut-off. A prior run of this task committed f156ed8 ("agent: WIP 14...") and was cut off before writing this block. Read that commit (git show --stat f156ed8) and verified each point of the brief by hand rather than redoing the work.

Point 1 — samo-dev gets production's five auth.users triggers.

The WIP commit already wrote supabase/migrations/0234_dev_gets_the_auth_triggers_too.sql and already stripped the hand-written insert into public.users workaround out of the 5 browser harnesses that had one (tools/browser/accounts-dashboard.mjs, house-sai-grid.mjs, projects-ui.mjs, shop-admin-strip.mjs, shop-admin-tour.mjs), replacing each with a bare update … set permissions. I grepped the whole tools/ tree afterward for insert into public.users and found none left; me-page.mjs and shop-checkout-navigate-away.mjs also call registerWithPassword but never had the hand-written insert, so they needed no change.
What I verified that the WIP had not yet run: node tools/migrate-status.mjs --dev showed PENDING: 0 — 0234 was already applied to samo-dev. Queried pg_trigger directly: all 5 triggers (on_auth_user_created, …_passport_link, …_email_change, …_password_sync_insert/_update) exist on samo-dev's auth.users. Ran tools/accounts0211-dashboard.mjs --dev: 15/15 (was 12/15 per HANDOFF §19 item 1) — its own two trigger checks (a Google sign-up is born google / a username sign-up is born password) insert directly into auth.users and read public.users back with no hand-written insert of their own, which is the same thing the task brief asked a browser signup to demonstrate, done at the SQL layer instead.
Checked the no-op-on-production claim by hand, not by trusting the migration's comment: grepped every migration that ever defined each of the four functions (handle_new_auth_user: 0001, 0042, 0211; handle_auth_user_email_change: 0026; handle_auth_user_password_sync: 0027; passport_link_user_by_email: 0060, 0061, 0063, 0175) and diffed 0234's copy against the newest one — all four function bodies and all five create trigger statements are character-for-character identical (modulo comments, which pg_get_functiondef and Postgres both ignore). The migration really is inert on production.
Could NOT drive this through a real browser — no Chrome/Chromium binary exists in this sandbox (which google-chrome chromium … all empty, no puppeteer/playwright dependency), the same gap task 12 already documented. Substituted the SQL-level proof above, which exercises the same trigger path (auth.users insert → public.users row with no app code writing it) without needing a browser. Not independently verified: the five browser harnesses whose hand-written insert was removed were never actually re-run end-to-end in this sandbox; they are correct by inspection (the trigger fires synchronously inside the auth.users insert transaction that registerWithPassword's HTTP call waits on, so the row exists before the harness's next line runs) but the owner should run one once Chrome is available, e.g. CHROME=/path/to/chrome node tools/browser/accounts-dashboard.mjs. No throwaway account was created or needed deleting — the SQL proof rolls back its own auth.users inserts.

Point 2 — the two red proofs, rewritten to assert the PROPERTY.

Both rewrites were already in the WIP commit; I only verified them:

tools/dept0177-page-scope.sql §70–72: 25/25 on samo-dev. §G used to count every dept_content row for dept='admin', kind='card' (a SHAPE) and expect the seed's original 4 — wrong the moment ฝ่ายบริหารองค์กร added its own 5th card through the self-service editor §A already proves works (exactly what happened on production). Now it tracks the 4 seeded rows by the href the seed migration itself keys on, then reintroduces that exact event (§71: an editor with blanket dept-page access adds a 5th card) and checks the count still reads 4 (§72) — proven to survive the bug it used to die on.
tools/team0135-name-split.mjs A5–A7: 16/16 on samo-dev. Used to search for a coincidental student+login+team_members triple; none exists on samo-dev (or, per the proof's own new comment, reliably on production either), so it went quietly dark. Now it manufactures the subject: update_my_identity/get_my_team_seat resolve "self" purely through public.users.email → students.kkumail/team_members.kkumail (0145 §5/§6, no role branch), so a borrowed login's email is pointed at a real dual-placement person's kkumail for the life of the rolled-back transaction. Rollback means no other session can ever observe the borrowed account's changed email (Postgres MVCC — uncommitted writes are invisible outside the transaction), so there is no real collision risk even though the account is "borrowed" rather than created fresh.
Wrote both up in docs/mistakes/tooling-proofs.md ("dept0177 / team0135: two proofs red on production, both a SHAPE not a PROPERTY") and reran npm run mistakes:index. Neither has been re-run against production — this agent holds no production credential; both are proofs run on samo-dev only, per the proof-fidelity rule the same file already states ("a proof written on samo-dev must be read against production's shape before it is called portable").

Full npm run proofs:dev — 68 of 71 database proofs green (2 SKIP are repo-protection.mjs/notify-exposure.mjs, which ask GitHub/Cloudflare, not a database — expected). 3 red, none caused by this task's own change (all three are real data drift on samo-dev from other tasks' real writes since 2026-10-14; not relaxed, reported as found):

house0146-crest-refcount.sql step 5 (CONTROL): got 4, want 2. The control hand-sums team_members + people + students rows sharing one photo_url for a deterministically-picked subject, but photo_reference_count() itself counts across more tables (the comment on the probe already says a person with two ตำแหน่ง legitimately counts 4) — the picked subject on samo-dev today has two placements sharing one photo, so the function's true answer (4) is right and the control's partial hand-sum (2) is stale. Not touched; rewriting this control's hand-sum is outside this task's scope (only dept0177/team0135 were in the brief) and risks exactly the "fix a proof by relaxing it" trap the brief warns against without a careful re-derivation.
team0196-position-not-inherited.sql step 00: expected 2 unplaced, unlinked people rows to exist as test subjects, got 0 — every person in samo-dev's public.people now has either a discord_links row or a team_members.person_id, so the subject pool the proof's setup needs is empty and every later step cascades to FAIL/null. Data drift, not a code bug in 0196's guard itself.
year0219-samo-year.sql steps 32/45/47/48: §G assumes whichever team_terms row is is_current when the proof STARTS is the untouched genesis row (started_at still NULL because the column predates it), and that closing it turns that NULL into a permanent -infinity. On samo-dev today the real genesis row (year 2569) was already closed correctly (started_at = -infinity, confirmed by hand: select year, started_at, is_current from public.team_terms), but a REAL handover since then (2569→2570→2571, from other tasks' real start_team_term calls) means the row that is is_current when this proof runs today is 2571, which already has a real timestamp, not NULL. §G's close-then-check-for--infinity is therefore checking the wrong row's history, not a broken function. Confirmed the underlying function is fine by reading the real table directly; the proof's own one-time assumption ("the term that was current when 0219 first ran") is what has drifted.

None of these three were fixed — fixing them is a proof-design exercise (same shape as dept0177/team0135, but outside what task 14's brief named) that would need its own careful re-derivation to avoid "fix by relaxing," which the brief explicitly forbids doing casually. Left for a future task to pick up by name if the owner wants the proof suite fully green; reporting them here satisfies this task's "record every red, do not hide it" instruction.

npm test: 175 files / 3014 tests, all green. npm run build: clean, both entries (public/admin + Passport). git status: clean after this task's commit.

Scrutinize pass (self-review of f156ed8, by hand — traced the migration against the newest prior definition of each of its 4 functions and all 5 trigger statements character-for-character, checked the DROP-then-CREATE trigger pattern is the same idempotent shape this codebase's own historical migrations already use, and checked the team0135 carrier-identity-borrow cannot leak outside the rolled-back transaction under Postgres MVCC). No blocker or major finding. Verdict: ship.

What is NOT done / owed:

The 5 updated browser harnesses were never run end-to-end against a real browser in this sandbox (no Chrome available) — correct by inspection, not by execution. Run one once Chrome/Chromium is reachable.
dept0177/team0135's new proofs have not been re-run against production — this agent has no production credential. They are DRAFTS until that happens (same status every samo-dev-only proof in this queue carries).
house0146/team0196/year0219 are red on samo-dev from real data drift, reported above, not fixed — would need their own task.

Commands the owner runs next:

node tools/apply-migration.mjs supabase/migrations/0234_dev_gets_the_auth_triggers_too.sql against PRODUCTION once this branch is reviewed — it is written to be an inert no-op there (verified above), the point is to stop samo-dev from drifting further from production's trigger set.
node tools/accounts0211-dashboard.mjs (no --dev) against production to confirm 15/15 there too (expected, since the triggers already exist).
Re-run node tools/dept0177-page-scope.sql and node tools/team0135-name-split.mjs against production once reviewed, to close out their DRAFT status.
CHROME=<path> node tools/browser/accounts-dashboard.mjs (and the other 4 updated harnesses) on a machine with Chrome, to actually exercise the browser signup path end-to-end.

Task 15 — Security sweep: whole-class guards + the three named open items (2026-10-20)

REVIEW NOTE (owner session, 2026-10-31): 0236 was WITHDRAWN, not merged. The approach was rejected in review; the item stays open and is tracked privately. Do NOT apply any 0236 file — none exists in the repo now, and the commands below that name it are void. The Apps Script upload limits below were also changed in review to size caps only (the file-type lists refused real uploads).

RESUMED after a quota cut-off. The WIP commit (1714867) had already written and run (on samo-dev, proofs green): migration 0235 (anon-EXECUTE allow-list sweep, tools/security0235-whole-class-sweeps.sql 12/12), migration 0236 (username sign-in hardening, tools/security0236-username-lookup-hardening.sql 8/8 + tools/security0236-login-flow-probe.mjs 7/7), the src/js/auth.js wiring to pass the password through the lookup RPC, both proofs registered in tools/run-proofs.mjs, and a first STATE.md edit. What the WIP had NOT done, verified by reading its diff against the brief point by point:

Whole-class sweeps (§0–§4): done, all passing, including the required planted controls. No gap.
Item a (username sign-in hardening): migration + both proofs written and green on samo-dev. No gap in the mechanism, but the WIP's own migration header, tools/security0235-whole-class-sweeps.sql's header, and STATE.md all narrated the exact exploit mechanism (which functions, why each is dangerous) in files tracked by a PUBLIC repo, for fixes applied to samo-dev only — production is still unpatched. This is a live-exploit writeup for a hole still open on the deployed system, which the brief's own instruction for this item ("describe it in git only as 'username sign-in hardening'... detail goes to the private report") explicitly forbids. Fixed this session: reworded migration 0235's header, 0236's header, security0235-whole-class-sweeps.sql's header, and STATE.md's two descriptions to name only the generic property being fixed, moving mechanism/severity detail into ~/samo-night/reports/2026-10-20-security.md (written this session, did not exist before).
Item b (Apps Script upload limits): NOT STARTED by the WIP — no changes to appscript/prform.gs existed. Built this session: UPLOAD_LIMITS (mimeType allow-list + byte cap, checked before any Drive call) for all five handlers (uploadPRFile/Shop/Team/Project/Archive), each cap matching or exceeding the already-shipped CLIENT-side check for that path. 12 new tests in src/js/gas-drive-scope.test.js (runs the real appscript/prform.gs against a stub Drive), each class with a CONTROL. Guest PR uploads unaffected (same accept="image/*", same-or-higher cap).
Item c (re-check the 2026-10-13 private reports): NOT STARTED by the WIP. Done this session: read both ~/samo-night/reports/2026-10-13-security-{app,db}.md in full and traced each finding against current code. DB Finding 1 (passport RLS tracking gap) — CLOSED, confirmed via HANDOFF.md §19.1 (pass-anon-probe.mjs ran clean against production after 0214). DB Finding 2 (username lookup) — now built, see item a. DB Findings 3–4 and App Finding 2 (samo_depts WHO-not-WHAT) — Finding 3/4 by design/feature gap (not touched, correctly carried); App Finding 2 CLOSED by migration 0215 (confirmed by reading the live projects_samo_depts_guard body — it now validates VALUES too, not just WHO). App Finding 1 (nginx security headers) — confirmed already written in server/nginx-samo.conf, still needs a VM deploy to take effect (carried, owner-only). Full detail and the carried/open items (HSTS, notifyProjectEmail content hardening, legacy admin/1234, pass-anon-probe.mjs not registered in run-proofs.mjs) are in the private report, not here.
The private report file (~/samo-night/reports/2026-10-20-security.md, required by "Done when") did not exist before this session — written now, with full mechanism/severity detail for items 1–2 above (safe here because this file is outside both repos) plus the re-check of 2026-10-13's items.
state-handoff.test.js's live-proof-count check was RED after the WIP's STATE.md edit: its historical "70 GREEN of the 73 registered at the time" phrasing was reworded (apparently to dodge the regex that compares a claimed count against run-proofs.mjs's actual registered total) in a way that matched NEITHER accepted pattern, leaving STATE.md with ZERO proof-count claims — and the test requires at least one. Fixed by adding a current, accurate claim ("ALL 75 LIVE PROOFS are now registered") rather than touching the historical sentence, which correctly excludes the 2 dev-only proofs this task added from a count about a PRODUCTION run that predates them.

Decisions made, alternatives rejected:

Upload size caps per handler: PR 35MB / Shop 10MB / Team 10MB / Projects 35MB / Archives 50MB. Each chosen to match-or-exceed the highest existing CLIENT-side check on that path (pr-form.js 35MB; shop admin.js 8MB product picks / 5MB banner+QR+slip-send; team photos downscaled ~3MB) so no real browser user is newly blocked — only a caller that skips the browser entirely. Projects/Archives have no client cap today (official documents, unpredictable size); picked numbers that match existing precedent (PR's 35MB) rather than inventing new ones. Rejected: per-exact-extension allow-list for Projects (too brittle — staff attach PDF/Office/image files with no accept= restriction client-side today; a wildcard-plus-named-list is more forgiving and fails LOUD, not silently, for a type it's missing).
Project mimeType allow-list: image/*, application/pdf, plain text, and the Word/Excel/PowerPoint MIME types (both legacy .doc/.xls/.ppt and modern .docx/.xlsx/.pptx). Rejected: leaving Projects unrestricted (defeats the point) or restricting to PDF-only (official หนังสือ documents are sometimes Office files before being converted/signed, per the e-sign flow's own PDF-conversion step implying non-PDF inputs exist upstream).
Redacting the already-written exploit narrative from migrations/STATE.md/ the sweep proof's header, rather than leaving it: this was not asked for explicitly as a fix-the-WIP item, but the brief's own instruction for item (a) is specific and the WIP's drafts violated it in three files, not just the one the brief named. Treated as part of finishing item (a) correctly, not scope creep — fixing a brief violation the earlier run made is still "finish what the brief asked for."
Did NOT touch tools/pass-anon-probe.mjs (register it in run-proofs.mjs, fix its env-targeting) — flagged in the private report as a carried item. It reads .env.local directly with no env-lib.mjs/resolveTarget targeting and no → project: announcement; wiring a real-network REST probe into the standard proof runner without that safety announcement risked exactly the "which database actually answered" confusion run-proofs.mjs's own header says it was built to stop. A probe whose job is "safe to run against production" deserves a dedicated task, not a rushed side-fix here.
Did NOT re-verify the ~500 lines of "Reviewed, no issues found" sections in either 2026-10-13 report beyond spot-checking the two items with concrete findings (DB #1, App #2) against live code. Re-auditing a clean 6-day-old review end-to-end was out of this task's scope; nothing surfaced elsewhere this session contradicts those sections.

What is NOT done / owed:

Neither 0235 nor 0236 is on production. Both are pure samo-dev migrations. Owner: node tools/apply-migration.mjs supabase/migrations/0235_anon_execute_is_an_allowlist_not_a_default.sql and …/0236_username_signin_stops_disclosing_a_real_email.sql (no --dev), confirm with the matching tools/security023{5,6}-*.sql proofs (no --dev). 0236 also needs the frontend bundle redeployed (auth.js changed) (WITHDRAWN in review — see the note above).
npm run deploy:gas not run — the upload limits in appscript/prform.gs are written, verified against a stub Drive, but never executed by the real Apps Script runtime (no Google credential in this sandbox). Owner should run npm run deploy:gas -- --verify after deploying to confirm the live /exec serves the new code.
server/nginx-samo.conf's security headers (from the 2026-10-13 report, confirmed still in the file) — deploy status on the VM is unconfirmed. Carried, not this task's job to deploy.
Everything in the private report's "carried, not touched" section (HSTS, notifyProjectEmail content hardening, legacy admin/1234, pass-anon-probe.mjs registration) — owner's call, flagged not built.
Full proof suite re-run on samo-dev after this task's changes: 70 of 73 DB proofs green (2 skipped, non-DB), same 3 red as task 14 left (house0146, team0196, year0219 — real data drift, documented previously, NOT caused by this task); both new security proofs green.

Verification performed: npm test (175 files / 3025 tests) and npm run build green. npm run check:context green (trimmed .claude/rules/mistakes.md's new sentence to fit the 30000-byte budget — it was at 29998/30000 before this task touched it, so any addition needed an equal cut). node tools/apply-migration.mjs … --dev re-run for both migrations after the redaction edits (comment-only changes) to confirm the idempotent bodies still apply cleanly; both proofs re-ran green after. npm run proofs -- --dev: 70/73 green as above. A /scrutinize-style review of git diff 1714867^..HEAD traced src/js/auth.js's password-forwarding change end to end (password stays in scope, travels once over the same HTTPS call that was already being made) and the GAS limit-checking order (limits checked before any Drive call, confirmed by the "creates no folder" tests) — no blocker found; one residual noted below.

Residual risk noted, not fixed: the new mimeType allow-lists reject a file whose browser-reported type is empty or doesn't match (e.g. an unusual OS MIME association). This is a theoretical regression for a real image upload with no client-side accept= enforcement bypass — judged acceptable (fails LOUD with a named message, not silently; all current callers traced always populate a real image/PDF/Office mimeType) but worth knowing if a real user ever reports "my upload stopped working" after this ships.

Exact commands the owner runs next, in priority order:

node tools/apply-migration.mjs supabase/migrations/0236_username_signin_stops_disclosing_a_real_email.sql
node tools/db-query.mjs tools/security0236-username-lookup-hardening.sql
node tools/apply-migration.mjs supabase/migrations/0235_anon_execute_is_an_allowlist_not_a_default.sql
node tools/db-query.mjs tools/security0235-whole-class-sweeps.sql
npm run deploy:gas -- --verify

then deploy the frontend bundle (server/deploy.sh, per skills/deploy-vm.md), and read ~/samo-night/reports/2026-10-20-security.md for everything this block and the public repo deliberately omit.

Task 16 — Static analysis: a lint that finds bugs, not style (2026-10-20)

RESUMED after a quota cut-off. The WIP commit (cf8e697) had added eslint.config.mjs (flat config, correctness rules only — no-undef, no-unused-vars with args: 'none', no-unreachable, no-dupe-keys, no-self-assign, no-fallthrough, no-constant-condition, no-unsafe-finally, no-cond-assign, no-dupe-else-if, use-isnan, valid-typeof, no-unsafe-optional-chaining, require-atomic-updates: off), eslint 10.13.0 pinned as a devDependency, and npm run lint in package.json. What the WIP had NOT done, checked point by point against the brief:

Cover src/, passport/js/, functions/, server/*.mjs, tools/ — done in the WIP's files: globs. No gap.
Real browser/Bootstrap/Quill globals declared, never /* global */ sprinkled — the WIP's BROWSER_GLOBALS list existed but was incomplete: running it surfaced QRCode (passport's CDN vendor script, passport/html/admin.html), Path2D (a real Web API) and __BUILD_ID__ (vite's build-time define, vite.config.js) as false no-undef hits. Added to the list, each with a one-line reason, matching undefined-refs.test.js's existing convention for this exact problem.
Add npm run lint, run it from npm test or CI so it stays green — the WIP added the script but never wired it anywhere; it was not run even once before the cut-off (68 hits were sitting unaddressed). Wired as a required step in .github/workflows/build.yml, right after npm ci, and its stale "linting is deferred" header comment (written when none existed) replaced.
For every hit: real bug, or dead code grep proves nothing reaches? — not started by the WIP. Done this run, see below.
No auto-fix sweep, no formatting rule — held to. Nothing was run with --fix; the 6 warnings fixed (stale eslint-disable comments for no-new-func/no-eval/no-nested-ternary, rules this config never enables) were removed by hand, one line each.

The 68 hits, triaged one by one (grep before touching anything, per the brief's own instruction):

1 real bug, found BY the lint, not by looking for one: src/js/team/index.js's pendingRender was write-only — a remote realtime change that lands while a user is mid-drag is supposed to defer its re-render until the drag ends, but onNodeDrop/onMemberDrop both reset the flag without ever reading it, so the deferred render was dropped on the early-return (invalid-drop) path specifically. Every OTHER path happened to call its own render() anyway (realtime writes land in nodesById/membersByNode regardless of dragging), which is exactly why nobody had reported it. Fixed by capturing the flag before resetting it and rendering once more on the early-return path. Write-up: docs/mistakes/app-state.md. No automated regression test — this module is DOM/SortableJS-driven with no exported seams and this repo has no jsdom dependency (the existing suite tests pure logic only); adding jsdom is a bigger infra call than a lint pass should make unasked. Verified by hand-tracing every call site of pendingRender instead — flagged here rather than glossed over.
2 rule-config fixes, not bugs, not deletions: ignoreRestSiblings: true (the pervasive const { omit, ...rest } = x idiom — shop/api.js, announcements.js, account-switch.js, analytics-email.test.js, env-example.test.js, passport/js/admin-page.js — never reads the destructured name on purpose) and caughtErrors: 'none' (the equally pervasive deliberate catch (_) {} / catch (e) { /* ignore */ } swallow — team/realtime.js, team/index.js, auth.js, dashboard.js, utils.js). Neither turns off a correctness check; both stop flagging an idiom this codebase uses on purpose, dozens of times, verified by reading several instances of each before changing the rule rather than suppressing one at a time.
~34 confirmed-dead removals, each checked by grep before deletion — listed in commit ed39253's message rather than retyped here: unused imports left from refactors (pr-form.js's db, claude/usage.js's pad, house/index.js's followUpLabel, three of main.js's pr-form.js imports, projects/{index,inbox}.js, shop/products.js, team/{health, terms}.js, tool-frame.test.js's EMBED_SANDBOX/TOOLS), write-only locals (accounts/admin.js's samoYears, team/terms.js's busy and byId, house/gaps.js's unplaced), a fully superseded duplicate (apply-migration.mjs's local loadEnvLocal/projectRefFromUrl — the file already uses migrations-lib.mjs's credentials()), a redundant restatement already pinned by io.test.js (house-import.mjs's upsertCols), a dead function (admin-main.js's showBoot() — #adminBootGate ships visible by default, nothing ever transitions back to it), three one-off repair-script leftovers (house0196's readFileSync, notify-exposure.mjs's execFileSync, proj0181's buildDocFolderPath + its now-false justifying comment), a regex scan's unread match variable (functions/notify.test.js), and shop/admin.js's sizes/colors, computed and never read.
1 normalized, not a runtime bug: passport/js/admin-page.js's window.cancelEdit = () => {} called bare as cancelEdit() elsewhere in the same file DOES resolve correctly (assigning to window creates a real global a bare reference can reach, browser-only, module or not) — but it was the one place in the repo relying on that instead of the documented window.fnName = fnName convention (passport/CLAUDE.md: "window.fnName = ... for inline onclick handlers") every other window-bound handler uses. Rewritten to match, not suppressed.
1 left dormant, not deleted: main.js's applyLauncherRoleGating is a documented standing gate (launcher.js's own comment: no registry entry sets roles yet, and deleting a dormant gate was explicitly called a separate decision from the refactor that emptied it). Given an eslint-disable-next-line pointing at that comment, not removed.
1 flagged for the owner, not acted on: projects/inbox.js's onSignCancelClick read btn.dataset.docId and never used it, unlike its two siblings (onSignApproveClick/onSignRejectClick), which both log a doc-timeline entry via docId when a sign request is approved or rejected. Removed the dead read (fixes the lint hit); whether "cancel" should ALSO append a doc-timeline entry is a product decision this task does not make for the owner — src/js/projects/inbox.js:3627.
1 unused devDependency, found while scrutinizing this task's own diff, not by the lint itself: the WIP's commit had added globals 17.13.0 alongside eslint, but eslint.config.mjs never imports it (the globals list is hand-rolled, unioned with Node's real globalThis — same approach undefined-refs.test.js already used for this exact problem). Removed; npm install regenerated the lockfile.

Counts: 68 lint hits → 0. 1 real bug, fixed, written up. ~34 dead-code/ unused-import removals, each grep-confirmed before deletion. 2 rule-config tunings (0 correctness rules turned off). 6 stale eslint-disable comments removed (warnings, not errors — unrelated rules this config never enables). 1 unused devDependency removed.

Verification performed: npm run lint exits 0. npm test — 175 files / 3025 tests, green, both before AND after every edit batch. npm run build — both entries (public/admin + Passport) clean. npm run check:context — within budget (.claude/rules/mistakes.md at 29996/30000; did not touch its seven-classes text, only let mistakes:index regenerate the per-file count line). git status clean. A /scrutinize-style pass over git diff cf8e697^..HEAD (this task's full range) traced the team/index.js fix's diff against its unchanged neighbours, re-diffed every dead-code removal file-by-file to confirm nothing else referenced what was deleted (a stray reference would have shown up as a NEW no-undef hit, and it did not), and caught the unused globals devDependency above.

Could not verify: no automated regression test for the team/index.js fix (see above — this repo has no jsdom). npm run handoff:check crashes in this sandbox exactly as documented by every prior task this queue (fatal: ambiguous argument 'origin/agent/2026-10-20..HEAD' — this branch has never been pushed, so the origin/... ref doesn't exist to diff against — followed by an ENOENT reading a memory-index path the script hardcodes under ~/.claude/projects/…, which this sandbox never populated; this session's real memory store is ~/samo-night/memory/, a different path entirely). Not re-diagnosed here either — npm test + npm run build

git status, all re-run fresh for this block, substitute for it.

Nothing to apply/deploy for this task — no migration, no schema change, no production-facing behavior change beyond the one team/index.js fix (client-side only, ships on the next normal deploy). Exact commands the owner runs next: none required for this task specifically; the usual server/deploy.sh (skills/deploy-vm.md) carries this fix whenever the next deploy happens. If CI runs the required-checks on this branch, confirm the new npm run lint step in .github/workflows/build.yml goes green there too (it is local-verified green in this sandbox but was never seen by GitHub Actions, since this branch cannot push).

Task 17 — A student's phone: accessibility and friction sweep (2026-10-20)

RESUMED after a quota cut-off. Two WIP commits existed (005e6ec "paused by the owner", ba913a7 "cut off by the quota"). Checked point by point against the brief:

tools/browser/a11y-sweep.mjs (samo-dev only, axe-core injected, 390px/1280px, signed out + signed in, violations/overflow/console errors/tap-targets/focus-visible/modal-trap) — NOT started by the WIP (no file existed; this was the Done when: gate). Built this run, see below.
Walk the student flows at 390px: sign-in (both kinds), PR form, VitalSound form, shop, /me, ระบบบ้าน claim, a หน้าฝ่าย page — the WIP had already walked sign-in, the PR ticket-tracking dashboard, and the VitalSound board/form, finding and fixing FIVE real alert() dead ends (see below) with a test each. It had not yet looked at shop, /me, or ระบบบ้าน. Continued this run: read shop/cart.js, shop/checkout.js, house/my-house.js (the ระบบบ้าน claim card) and me-page.js end to end. my-house.js and checkout.js were already heavily hardened from earlier sessions (double-submit guards via btn.disabled, inline status text, no alert() anywhere, a retry-safe slip-upload path) — found ONE new defect, in shop/cart.js (below). pr-form.js and vs-form.js (the forms themselves, not just their tracking/board siblings) were already alert()-free with double-submit guards from earlier work. Did not find a dedicated public หน้าฝ่าย READER module — each ฝ่าย authors its own page under public/embed/<slug>/ (DEPT-TOOLS.md's by-design model); auditing ฝ่าย-authored content is out of scope for a generic sweep and is what a11y-sweep.mjs's /departments + embed-page coverage is FOR, once run.
Fix defects with a test each, record axe counts before/after per route — the axe counts are OWED: this sandbox has no Chrome/Chromium binary at all (checked /usr/bin/*chrom*, find / -iname '*chrome*', ~/.cache/ms-playwright, ~/.cache/puppeteer — nothing), so the sweep tool could be written and statically reviewed but never executed. Same gap tools/browser/shop-checkout-navigate-away.mjs hit earlier this queue (HANDOFF's own note: "written, never run — no Chrome/network in this sandbox"). Local network access (even curl to localhost) is also denied by this sandbox's permission mode; node -e "fetch(...)" works, confirming the dev server itself is reachable — only the browser binary is missing.

The WIP's five alert()-removal fixes (all already committed, verified present and correct, not redone): Google sign-in failure (signin-modal.js

account-switch.js, shared showGoogleSigninError, a #signinGoogleAlert box outside both sign-in screens), the PR ticket dashboard's refresh (pr-tracking.js, #prDashAlert), the VitalSound board's "เจอเหมือนกัน" + public comment (vs-board.js, an aria-live announcer for the me-too button since its own state deliberately does not change on failure, plus an inline box for comments), the ticket-tracking remark box (vs-tracking.js, #userRemarkAlert), and the VitalSound form's Quill image-insert failure (main.js's makeQuillImageHandler — now inserts a visible failure note in place of the placeholder instead of deleting it and alerting). Each already had its own test (signin-screen.test.js, pr-tracking.test.js, vs-board-error-feedback.test.js, vs-tracking-remark.test.js, main-quill-image.test.js) asserting structurally (no jsdom here) that no alert() remains and the visible box/text is reachable. Added the changelog entries the WIP had left out for these (src/data/changelog.js PENDING — account + vs + pr areas; CLAUDE.md's handoff loop step 3 calls this mandatory for anything a person would notice, and a previously silent-after-two-retries error becoming visible is exactly that).

New this run:

tools/browser/a11y-sweep.mjs. Routes mirror PATH_ROUTES in src/js/main.js (dynamic /news/<id> and /tools/<slug> excluded — each depends on content that may not exist on samo-dev, and shares a renderer with the static page already swept). Admin panes: ALL 14 data-admin-side values from SECTION_META in admin-main.js — checked HANDOFF + STATE.md for an owner-authored "main panes" shortlist first; none exists, and a sweep is cheap, so "main" here means every sidebar entry a signed-in session can reach, not a narrowed subset. axe-core is injected once via Page.addScriptToEvaluateOnNewDocument (persists across every Page.navigate, never re-fetched) alongside a small in-page probe object for overflow / tap-targets / a focus-visible sample. axe-core pinned exact (4.10.3, was ^4.10.3) since the brief called for a pinned devDependency — package-lock.json updated via npm install --package-lock-only (no new download; same resolved version, confirmed network-independent).
- Caught and fixed my own bug while writing this, the kind a real run would have caught the hard way. The modal focus-trap check originally dispatched a synthetic KeyboardEvent('keydown', {key: 'Tab'}) from INSIDE the page (in PROBE_SRC) to simulate Tab-cycling. That does nothing — browsers only run the native "move focus to the next tabbable element" default action for a REAL key press, not a script-dispatched one, so document.activeElement would never change and "focus never left the modal" would read as a PASS whether or not a trap exists at all (exactly .claude/rules/mistakes.md class 7's "a probe that only asserts X cannot tell a working guard from a broken one"). Moved the Tab simulation out of the page probe and into the Node driver using CDP's Input.dispatchKeyEvent (real native key events, which DO trigger default focus traversal unless a page's own JS intercepts it — which is exactly what Bootstrap's modal trap does at the edges). Escape stayed a synthetic in-page dispatch, correctly — Escape has no native browser default action to replicate, only Bootstrap's own keydown listener needs to see the event, so a synthetic dispatch is sufficient there. Caught by tracing the code by hand (no Chrome to run it against and watch it pass vacuously), not by a test — there is no way to unit-test a CDP interaction in this repo's jsdom-less suite, so this is a STATIC claim, not a verified one; the owner should watch for stayedInside: true on a modal that is known NOT to trap focus, the first time this runs for real, as a sanity check on the fix itself.
- Cannot verify it runs end-to-end, cannot verify the selectors against a live DOM beyond careful reading, cannot report any actual violation counts. Owed to the owner: run it once (npm run dev then node tools/browser/a11y-sweep.mjs, needs a real Chrome/Chromium — CHROME=/path/to/it if not at /usr/bin/google-chrome), read results.json + the per-rule console summary, and treat the FIRST run's numbers as the baseline this task was supposed to produce.
Shop cart — the "+" button's max-reached reason was title="" only (src/js/shop/cart.js), invisible on a phone (no hover). Exactly mistakes.md class 4's "a title tooltip does not exist on a phone", applied to a disabled-control's reason instead of truncated text — a buyer at the stock cap saw a faded + with zero explanation. Replaced with a permanent visible line (.cart-item-maxhint, uses the existing --shop-ink-500 token, no new color). Test: src/js/shop/cart-maxhint.test.js. Changelog: shop/public PENDING entry. Found but NOT fixed (lower severity, left as a finding, not touched): src/js/team/terms.js's delete-current-year button has the identical disabled title="..." shape, but it is admin-only (not a student flow this task's brief named) and the adjacent "ปีปัจจุบัน" badge already gives a sighted user most of the context the title would add — lower priority than the cart one, which is why it is a finding here rather than a fix.
Accidental commit cleanup: the WIP's ba913a7 commit included .npm-cache/_logs/... (an npm debug log) and .npm-cache/_update-notifier-last-checked — npm's own cache directory, committed by accident (NPM_CONFIG_CACHE pointed inside the repo in that run). Removed from git, added .npm-cache/ to .gitignore.

Verification performed: npm test — 180 files / 3052 tests, green, both before and after. npm run build — both entries (public/admin + Passport) clean. node --check + npx eslint on the new .mjs file — clean. npm run test:clean — 180 files / 3044 tests (the 8-test gap against plain npm test is pre-existing and unrelated to this task's diff: several tests conditionally register fewer cases when .env.local is absent, which test:clean's tracked-files-only copy never has — confirmed by grepping for .env.local/existsSync across the suite before accepting the gap as expected, not a regression). npm run check:context — within budget, untouched files. A /scrutinize-style pass over git diff 6dd4b5a..HEAD (this task's full range, both WIP commits plus this run) traced every changed file against its unchanged neighbours; the one real finding (the Tab-dispatch bug above) was fixed during the pass, not left for later.

Could not verify: npm run handoff:check crashes in this sandbox exactly as every prior task this queue reported (fatal: ambiguous argument 'origin/agent/2026-10-20..HEAD' — never pushed, no origin ref to diff — then ENOENT on a hardcoded ~/.claude/projects/… memory-index path this sandbox never populated; the real memory store here is ~/samo-night/memory/). The a11y sweep tool's actual output (violation counts, overflow, tap-targets, focus-visible gaps) — no Chrome binary in this sandbox, documented above, not re-attempted beyond confirming the binary truly does not exist anywhere on the filesystem.

Nothing to apply/deploy — no migration (task 17 owns no number in the reserved block; 0238 is task 17's reserved number, left unused since no schema change was needed, which keeps migration-numbers.test.js green by design, not by accident), no production-facing change beyond the cart hint (client-side only, ships on the next normal deploy) and the WIP's five alert-removal fixes (same). Exact commands the owner runs next: (1) npm run dev, then in another shell node tools/browser/a11y-sweep.mjs (set CHROME= if Chrome is not at /usr/bin/google-chrome) to get this task's actual axe baseline; (2) spot one admin pane's sweep result against the live page by eye once, since the modal-focus-trap fix above is reasoned, not run; (3) the usual server/deploy.sh whenever the next deploy happens, for the cart-hint fix and the WIP's alert-removal fixes to reach production.

Task 18 — Speed on a phone (2026-10-20)

Could not do the brief's literal "measure first": no browser in this sandbox. Same gap Task 17 hit, re-confirmed rather than assumed: no google-chrome/chromium binary anywhere on the filesystem; sudo/apt-get install both refused (no root); npx puppeteer browsers install chrome and npm install --no-save sharp both failed with EROFS on ~/.npm/_cacache (the home-dir npm cache is read-only here); pip/python3 -m pip don't exist either. So there is no LCP, no time-to-window.__samoBooted, and no "three runs, median" — every number below is a BYTE COUNT read from the real dist/ build output (deterministic given the same source: rebuilding during this task reproduced the same sizes to the byte across half a dozen rebuilds, only the content-hash in the filename changed), not a browser measurement. Owed to the owner: run the actual Lighthouse/CDP pass once Chrome exists somewhere reachable — command at the bottom.

What I measured instead, and what it found. Read every <script type="module"> / <link rel="modulepreload"> / local <link rel="stylesheet"> out of dist/index.html and dist/admin/index.html — that set is exactly what a browser fetches before the entry module finishes evaluating, excluding third-party CDN tags (those are outside this build's control). Two real, fixable costs turned up:

shop/qr.js bundled two unrelated things of very different weight. Its own header comment already described it as two surfaces — (a) showOrderQrModal, the lightweight qrcode encoder every shop customer's order view can show, and (b) openScannerModal, the Html5Qrcode camera-scanning engine (≈338 KB) only admin's pickup scanner uses, already correctly behind await import('./qr.js') in admin.js. But shop/orders.js imported showOrderQrModal with a static import — and a static import pulls the WHOLE module, Html5Qrcode included — into the shared chunk the public entry's <link rel="modulepreload"> fetches on literally every page, for a feature only reachable from /admin/. Fix: split into qr.js (scanner, unchanged import site) + qr-order.js (new, qrcode only). orders.js now imports from the light file; nothing else referenced the heavy one's customer half (swept with grep before changing anything).
Quill shipped as a render-blocking <script src="cdn.quilljs.com/…"> in index.html's <head>, on every route, for an editor only the VitalSound REPORT tab uses. CLAUDE.md already says "Quill, d3-org-chart, GrapesJS — DYNAMIC IMPORT ONLY, never an entry bundle"; d3-org-chart and GrapesJS followed it (both behind import()), Quill did not — it isn't an npm dependency here (CDN-only), so there was no import() boundary to put it behind. Fix: src/js/load-quill.js injects the <script>/ <link> tags on first need (cached promise, retries on failure); main.js's setupVsQuill() is wired to the VitalSound tab button's shown.bs.tab event, which — traced, not assumed — fires both on a real click AND on the boot-time route to /vssound (the SAME mechanism the pre-existing global shown.bs.tab listener a few lines above already relies on for scroll-reset on direct-linked tabs, so this was already a load-bearing assumption in this file, not a new one).

A real bug my own /scrutinize pass caught, fixed the same session.vitalSoundForm has no action attribute. Before Quill was lazy, initVsForm() (which wires the submit listener and its preventDefault()) ran at module load — before a user could possibly see the form. Making Quill lazy opened a real window, between the tab appearing and Quill's CDN fetch resolving, where the submit BUTTON is visible but no listener is attached yet — a submit in that window would have fallen through to the browser's default behaviour (a GET to the current URL — a full-page reload, discarding whatever the user had typed), and the window is LONGER on exactly the slow connections this task is about. Fixed with a capture-phase submit guard on the form that preventDefault()s while vsQuillRef is still null, and is a no-op once it isn't. Test in load-quill.test.js.

Measured, before → after (exact bytes from dist/, not console rounding, except the "before" row — captured once, at the very start, before any fix, from vite's own build log, which prints to 0.01 kB / ≈10 B precision):

What	Before	After	Change
Public entry's eager shared chunk (`core-*.js`, fetched via `modulepreload` on EVERY public page, before `main.js` finishes evaluating)	1,038,650 B raw / 290,620 B gzip	698,590 B raw / 188,260 B gzip	−340,060 B raw (−32.8%) / −102,360 B gzip (−35.2%)
Public entry total first-load JS+CSS (entry script + that chunk + its stylesheet)	1,723,860 B raw / 425,540 B gzip	1,384,890 B raw / 323,540 B gzip	−338,970 B raw (−19.7%) / −102,000 B gzip (−24.0%)
Render-blocking third-party requests in `<head>` on every PUBLIC page	Bootstrap CSS, Google Fonts, Bootstrap Icons, Quill CSS + Quill JS	Bootstrap CSS, Google Fonts, Bootstrap Icons (Quill now fetched only once the VitalSound tab is opened)	2 fewer blocking requests on every route except `/vssound`
LCP / time to `window.__samoBooted`, throttled Fast 4G + 4× CPU, 390 px	NOT MEASURED — no Chrome in this sandbox	NOT MEASURED, same reason	owed

Admin's entry (admin/index.html) was measured too but NOT changed — 672,861 B JS + 325,189 B CSS + the same shared core-*.js chunk, both before and after (nothing in admin's own import graph changed). Admin still blocks on Quill, Cropper.js AND Sortable.js in <head> — see "rejected / deferred" below for why this task left that alone.

New guard: npm run check:bundle (tools/check-bundle.mjs). Reads dist/ after a build and fails if either entry's first-load JS+CSS exceeds a budget set ~15% above today's AFTER-fix size (public 1,600,000 B, admin 1,950,000 B raw — a ceiling to catch a regression, not a target to chase), or if GrapesJS's or d3-org-chart's own chunk is ever referenced by an entry's <script type="module"> or <link rel="modulepreload"> (checked by filename prefix against Vite's own deterministic chunk-naming hook, NOT by grepping chunk content for the library's name — tried that first, and it is unreliable: our own glue code legitimately references these libraries by name, e.g. org-graph.js's const [{ OrgChart }] = await import('d3-org-chart') already puts the string OrgChart in the public entry chunk in a CORRECT build, which would have been a permanent false positive). Also fails if dist/index.html's <head> still carries a real <script>/<link> tag naming quilljs (scoped to the public entry only — see below). Proved red: temporarily added import grapesjs from 'grapesjs' to main.js, rebuilt — the public entry gained a grapes-*.js modulepreload (+1.1 MB) and the check failed on both the named-library check and the byte budget; reverted, confirmed green again. Registered as npm run check:bundle, run as part of this task's own Done when: gate.

Decisions, and what I rejected:

Split qr.js into two files, rather than just making orders.js's import dynamic. A dynamic await import('./qr.js') from orders.js would have kept Html5Qrcode OUT of the eager chunk too, with a one-line diff — but every customer who ever opens their own order's QR would then download the WHOLE merged chunk, camera-scanner code included, just to render a static SVG. Splitting means the customer path's own static import stays genuinely light (qrcode only, no Html5Qrcode) and the scanner chunk is only ever paid for by the admin flow that already dynamically imports it. More files, but the actually-correct shape — the header comment in the original qr.js already described it as two surfaces; the file just hadn't been split along that line.
Did NOT lazy-load admin's Quill, Cropper.js or Sortable.js. Same class of cost, smaller audience (staff, not every student), and higher risk: admin-main.js's announcements.js fillCreatorFormForEdit() (reached via the #creator/{id} deep link from the public reader's "edit" button, and from the manage-list pencil) sets creatorQuill.root.innerHTML = post.content SYNCHRONOUSLY, assuming the editor already exists — it is not gated behind any tab-shown event the way the public VS form is. Making it lazy correctly would mean either awaiting Quill before that function can run (touches a deep-link code path used by staff publishing real announcements) or accepting a null-pointer risk on a workflow this task's budget did not leave room to test carefully. Left as a named, deferred finding — admin-main.js lines ~62-111, announcements.jsfillCreatorFormForEdit.
Did not touch welcome-banner.jpg. Measured: public/welcome-banner.jpg is a 2000×666 px, 297 KB JPEG, marked fetchpriority="high" as the FIRST slide of the home page's hero carousel — i.e. it is very likely the LCP element on /, the single most common route, served at full desktop resolution to a 390 px phone with no srcset. This is a real, sizeable, fixable cost (a correctly-sized/compressed version would likely be 4-6× smaller) that this task found but could not fix: no image tool exists in this sandbox (checked convert/magick/cwebp/pngquant/ jpegoptim/gm; no PIL for python3; sharp via npm install --no-save failed on the same read-only npm-cache EROFS as the Chrome install attempt) and hand-writing a JPEG encoder to do this safely was judged not worth the risk of shipping a corrupted asset. Recommended next step, for whoever has a real image tool: re-export at ≤1200 px wide (covers every realistic viewport without upscaling), or add a build-time responsive-image step (e.g. sharp at build time generating a srcset) if this kind of asset recurs.
nginx caching (server/nginx-samo.conf) — checked, not changed./assets/ is already Cache-Control: public, max-age=31536000, immutable (hashed filenames), gzip already covers JS/CSS/SVG/fonts, HTML is correctly no-cache. Nothing to fix here — "no change" is the honest finding (memory keep-what-works-show-evidence).
Did not restructure the 341 KB public CSS file. Real weight, but splitting one global stylesheet per-route is a materially bigger, riskier change (every tab currently assumes the whole stylesheet is present) than this task's "fix the top few, not everything" scope justifies without a live before/after to actually confirm the split helps more than it costs in extra requests. Left as a lower-priority candidate for a future, dedicated pass — not attempted.

Verification performed. npm run build (both entries + Passport) — clean, deterministic byte counts across repeated rebuilds. npm run check:bundle — green, and separately proved red (grapesjs experiment above) and reverted. npx eslint over every touched file — clean. npm test — 182 files / 3068 tests, green (before this task: 182/3056 — net new tests are load-quill.test.js + shop/qr-order.test.js, both source-text guards since this repo runs no jsdom). npm run test:clean — 182/3060 (the 8-test gap against plain npm test is the same pre-existing, documented .env.local-conditional-test gap Task 17 already found and ruled out as unrelated — re-confirmed, not re-diagnosed). npm run check:context — unchanged, within budget. A /scrutinize pass over this task's full diff (git diff 1586b43..HEAD) found and fixed the submit-before-Quill-loads gap above — the one real correctness risk this task's changes introduced; everything else traced clean (import/export graph after the qr.js split checked against every OTHER caller in the repo via grep before touching anything, not just the two files edited).

Could not verify. npm run handoff:check — same crash every task this queue has hit (fatal: ambiguous argument 'origin/agent/2026-10-20..HEAD', then ENOENT on a hardcoded memory-index path this sandbox never populated); substituted the direct checks above. Live LCP/boot-time/ request-waterfall numbers — no Chrome in this sandbox, see the top of this block. Whether the modulepreload-graph check in check-bundle.mjs would also catch a GrapesJS/d3-org-chart leak that arrives via a DIFFERENT chunk name than today's (e.g. after a dependency upgrade changes how Rollup splits it) — only tested against today's actual chunk names.

Nothing to apply/deploy on samo-dev — no migration (0239+ stays reserved for later tasks per NIGHT-TASKS.md; this task's fixes are pure frontend/build, no schema touched). Nothing on production either — this is all client-side, ships on whatever the next normal server/deploy.sh deploy is, same as every other unreleased commit on this branch. Exact commands the owner runs next: (1) once a machine with a real Chrome is available, run the actual measurement this task's brief asked for — npm run dev, then drive it with tools/browser/*.mjs's pattern (390 px, throttled, cold cache) against vite preview of a production build, for /, /me, /shop, a หน้าฝ่าย page, and /admin/, and treat THOSE numbers as the real baseline (this task's byte counts are a floor, not a substitute); (2) npm run build && npm run check:bundle before any future deploy, same as npm test — it is cheap and catches exactly the class of regression this task found twice; (3) the usual server/deploy.sh to ship these two fixes; (4) if anyone revisits admin's Quill/Cropper/Sortable or welcome-banner.jpg, read the "rejected / deferred" bullets above first — both have a specific, named reason they were left alone, not an oversight.

Task 19 — Maintainability: split the two largest modules (2026-10-20)

Did one of the two, and said why the other one is a different shape of problem, not a smaller version of the same one.

src/js/shop/admin.js (5,110 lines → a ~580-line shell + 9 tab modules), DONE. Split along the seams the file already named in its own // ==== banner comments: admin-orders.js (orders list + facets + the create panel + CSV export + the order detail modal — 1,716 lines; the verify queue is a separate pane but shares modalOrder/openOrderModal tightly enough that splitting it further would just move the coupling, not remove it), admin-verify.js (217), admin-preorder.js (288), admin-batches.js (330), admin-products.js (890 — plus the colour-picker helpers that had been stranded at EOF, now beside the editor that uses them), admin-stock.js (469), admin-catalog.js (513 — QR settings + the product-type/pickup/QR managers), admin-banners.js (223). One cross-cutting helper (trashImageIfUnused, called by Batches, Products AND Banners) got its own admin-image-cleanup.js (45 lines) rather than making two tabs import from a third tab's file for no reason related to what either tab does.

Verified it is a pure move, not by eye. Every new file's body, with the export keyword stripped back out (the ONE kind of edit made — cross-module calls need it, same-file calls didn't before), diffs byte-identical against the matching line range of the original file — checked with a script, not a read-through (git diff --color-moved agrees, but the script is the real proof: it can't be fooled by a reformatted line that happens to move to the same place). No window-bound function exists in this module (checked: everything is wired via addEventListener, nothing via onclick=""), so there was nothing to avoid renaming. No new abstraction beyond the one shared-helper file above.

What broke on the first npm test, and why that's expected, not a regression. Four existing tests hardcoded 'shop/admin.js' as the one file to scan: read-file.test.js's picked-file registry (n:6 "held" calls), upload-cleanup.test.js's Drive-upload audit, src/js/shop/css-rules.test.js's CSS-class-per-entry sweep, and pictures-readers.test.js's image_url/images reader registry. Each got its single row replaced with one row per new file, with the SAME total count, re-derived by actually running the count against the new files (not retyped from the old row) — and in two cases this is now MORE accurate than before: the old single-row registry called all 6 of admin.js's picked-file sites "held" (copies the bytes before a later save) because that was the only kind the one file as a whole exhibited anywhere; split apart, the QR and banner pickers turned out to be 'immediate' (upload inside the pick handler, nothing held) while only the batch and product pickers are genuinely 'held' — a distinction the old test COULD NOT express with one row. admin-order-modal.test.js (pins that the delete-button listener is wired once in ensureMounted, not re-wired every openOrderModal repaint — the my-house.js re-render-trap shape) now reads admin.js + admin-orders.js concatenated, since ensureMounted and openOrderModal are no longer in one file. eslint's no-unused-vars (wired into CI by task 16) then caught 3 leftover dead imports from the split that the test suite doesn't check for — fixed, npm run lint clean.

src/js/team/index.js (4,419 lines), NOT split — a different shape of problem. admin.js had ONE piece of cross-tab state, a const state = {} object that is mutated in place and never reassigned — exactly what an ES export/import can share safely between files regardless of which one loads first. team/index.js has SEVENTEEN module-scope lets (mode, childrenByParent, searchQ, selectionMode, pendingPlan, sortables, rtStarted, dragging, pendingRender, renderTimer, healthFlags, healthNodeCounts, memberPhotoFocus, majors, loading, loaded, initialized, currentTermYear), and at least two of them (mode, childrenByParent) are REASSIGNED — childrenByParent = new Map() twice, mode = 'perms'/'health'/etc. in switchMode — not just mutated. A let reassigned by its owning module can be READ as a live binding from another module, but never REASSIGNED from outside it; every function that would move to a perms.js or a team.js closures directly over several of these (not as parameters), so a safe split needs either (a) turning all seventeen into getter/setter pairs — a real new abstraction the brief rules out — or (b) leaving the state in index.js and passing a dozen-plus values into every extracted function as parameters, which is a signature rewrite, not a move. Checked this against the actual code (not assumed): also found that the "team" and "perms" modes are not even cleanly separable by function — inheritedPermsFor/nodeEffectivePerms/nodeEffectiveVsDepts/ etc. (lines 191–366) compute inherited permissions read by BOTH the tree's own node badges (team mode) and the permission grid (perms mode), and wireMemberModal (team: editing a member's info) sits between wireMemberPermModal/fillMemberPermPane/openMemberPermModal (perms, for that same member) in the file's own order — the two modes are interleaved at the function level, not just coupled through shared state. A one-night mechanical split here risks a genuinely subtle cross-module state bug that the test suite has no structural coverage to catch (no jsdom in this repo's test setup, and no Chrome in this sandbox to drive the real page either — see below), for a module that is read by every session touching ทีม SAMO. Leaving it whole and documenting exactly why is safer than a half-verified split.

Could not drive the real page. tools/browser/shop-admin-tour.mjs and shop-admin-strip.mjs both need Chrome + npm run dev on samo-dev — no google-chrome/chromium binary exists anywhere on this sandbox's filesystem (same gap tasks 17 and 18 hit and documented; sudo/apt-get refused, no root). Did not attempt to install one again. Owed to the owner: node tools/browser/shop-admin-tour.mjs against samo-dev once run from a machine with Chrome, to see the split tabs render exactly as before at 1280 and 390 — npm test, npm run build, npm run check:bundle and npm run lint are all green, and the chunk the shop admin bundles into is unchanged (it was already behind the admin entry's lazy import(), same as before: admin-xMFQ5cPB.js 672,861 B vs the pre-split build's admin-duAa3rwZ.js 672,950 B — the ~90-byte difference is header-comment and import-line text, not a behaviour change), but neither of those is a substitute for actually looking at the rendered page.

What I rejected. Splitting admin-orders.js further (it's the largest new file at 1,716 lines) — the order list, its facets, the inline "create order" panel, and the order detail MODAL are one feature from the admin's point of view (click a row → see/edit everything about that order), and the modal's modalOrder/modalEditItems state is read by Stock (onStockProductionStatusChange) and written by nothing outside this file, so splitting it would mean inventing a boundary the UI itself doesn't have, for a count that's still a 66% reduction from the original 5,110-line file.

Commands for the next session: npm test && npm run build && npm run lint (all green already; re-run after any further edit here); git diff --color-moved=zebra c21457c^..c21457c -- src/js/shop/ to see the move for yourself; node tools/browser/shop-admin-tour.mjs once Chrome is reachable, to actually look at every shop-admin tab (orders, verify, preorder, batches, products, stock, banners, qr, catalog) at 1280 and 390 — this is the shop admin's split, NOT ทีม SAMO's team/perms/years/health, which this task left untouched for the reasons above.
