Fixes the safe, agreed findings from the 11 November 2026 adversarial review of the external "Ward Flow — Deep Performance Audit" (WF-01 to WF-57, written against bd16e4ad). "WF-xx" below means that document's finding numbers, not the repository's own WF-Fxx items. One PR, per D-107's fewest-PRs rule; each finding is its own commit.

Engineering only. No visible change, no wording change, no What's new file. No script budget or size cap is raised or re-baselined.

What changes

Budget gate: tightening only

  • WF-03: the 1.5 KB tolerance can no longer stack.
    • Before: judgeAgainstMain compared each PR with a main that already held the previous PR's tolerance. Run with the repo's own function, 20 PRs at +1.5 KB each all passed, a +30 KB drift.
    • Now: growth within the tolerance passes only while the route stays within 3 KB (2 × tolerance) of its fixed budget.
    • A PR that measures no bigger than main still always passes. So a main that drifted is never pinned on a PR that didn't grow it, which is the 4 Nov intent.
    • The new test shows the 20-PR chain stopping after at most 2 PRs.

Measurement: report only, never judged (WF-01, WF-02, WF-06, WF-18)

  • What's reported: after its verdict, check-script-budget.mjs prints, saves under report in measured.json and writes to the CI step summary:
    • each budgeted route's stylesheet size;
    • the preloaded script the budget does not count;
    • the script every budgeted route shares (the shared shell);
    • four heavy routes with no budget line (REPORT_ROUTES, triage first).
  • It can't fail a build: an error in this part is only printed, and the exit code is unchanged.
  • Measured on a local production build of 8d948c74:
    • Triage: 719.3 KB of script and 161.6 KB of CSS, with no budget. The largest budget is 667.4 KB.
    • CSS: 115.8 to 191.2 KB across the budgeted and report routes.
    • Preloaded script the budget doesn't count: about 70 KB per route.
    • Shared shell: 479.1 KB.
  • Setting any new limit is Josh's decision, from a measured baseline. This PR sets none.

Render cost, no visible change

  • WF-27, Movements: the Back (popstate) listener was removed and re-added on every movements change. It now reads the latest movements through useEffectEvent and is added once.
  • WF-25, governance register (that part only): each event's reviews were found by scanning every review, several times per row. reviewHistoryLookup now builds the lookup in one pass and returns the same reviews in the same order.

Refuse, don't throw (WF-50, inbox half)

  • ACKNOWLEDGE_INBOX_ITEM, and every other inbox row event, with no text row id threw a TypeError in the audit capture (ward-audit.ts) and the reducer. A missing id is now treated as blank, so the existing refusals apply. No wording change. The server already failed closed, so this only affects the local demo reducer.

Evidence (local, box)

  • Tests that fail before and pass after:
    • ward-ci-budget-heal (2 new cases failed on the old judge).
    • ward-inbox-acknowledge-malformed (9 of 9 threw before).
    • ward-movements-popstate-listener (4 listeners added after two escalations instead of 2).
    • ward-governance-review-history and the report-only cases in ward-script-budget are new modules or exports, so they couldn't run before.
  • Related suites pass:
    • movements screen: 43
    • governance registers and admin role
    • script budget: 55
    • budget heal: 24
    • inbox/audit reducer suites: 18 files, 157 tests
  • Checks on the changed files:
    • lint: clean
    • full typecheck (npm run typecheck): clean
    • docs links: 0 broken
    • doc facts: pass
    • protected safety tests: PASS (none touched)
    • diff integrity: PASS (40 to 51 cases)
    • CI contracts: OK
  • Phone script budget: a local production build of the pre-rebase branch (base 72d99b1cf, before the inbox commit) was within all 9 budgets, with 1.2 to 5.2 KB of headroom. No budget line was touched. After rebasing onto 5b08a5ebe and adding the inbox commit (a few bytes in the reducer), I didn't rebuild locally, so this PR's CI build is the measurement of record.

Not in this PR (owned by another open PR or needing Josh)

View guided diff

WF-03: judgeAgainstMain compared each PR with a main that already held the
previous PR's tolerance, so 20 PRs could add 30 KB with every build green.
Growth within the tolerance now passes only while the route stays within
3 KB of its fixed budget; a PR measuring no bigger than main still passes.
Tightening only; no limit changes.
… route sizes

Report only, never judged (performance audit WF-01, WF-02, WF-06, WF-18).
After the budget verdict the script prints, and saves under "report" in
measured.json (and the CI step summary), each budgeted route's stylesheet
size, the preloaded script the budget does not count, the script every
budgeted route shares, and four heavy routes with no budget line, triage
first (719.3 KB of script on 8d948c7). A failure there is only printed.
No new limit: setting one needs Josh's decision from a measured baseline.
…hange

Performance audit WF-27. The popstate listener depended on the movements
array, so every change removed and re-added it. It now reads the latest
movements through useEffectEvent and is added once for the page's life.
The new test failed before (4 listeners added after two escalations
instead of 2) and passes after; Back to a missing movement still closes.
Performance audit WF-25 (governance part). historyFor scanned every review
for each event, several times per row, so the register's work grew with
events times reviews as the audit trail grew. reviewHistoryLookup builds
the lookup once per render and returns the same reviews in the same order
(same event, same world generation). The new test pins equal answers to
the old filter and a single read of the reviews. No visible change.
Performance audit WF-50 (inbox half). An ACKNOWLEDGE_INBOX_ITEM, and every
other inbox row event, with no text row id threw a TypeError out of the
audit capture and the reducer instead of being refused. A missing id is
now treated as blank, so the existing refusals apply; no wording change.
The new tests failed before (9 of 9 threw) and pass after.

Summary by CodeRabbit

  • Bug Fixes
    • Malformed or missing inbox item IDs no longer cause errors; affected actions are rejected safely.
    • Returning to a movement from browser history now restores its details only when the movement still exists.
  • Documentation
    • Clarified how inherited script-budget overages are assessed and which asset-size measurements are informational.
  • Chores
    • Added CI asset-size reports for scripts, stylesheets, preloads, and shared page assets. These reports do not affect build results.

Walkthrough

The pull request tightens inherited script-budget checks and adds report-only asset measurements. It also guards inbox handling against malformed IDs, indexes governance review history, stabilizes the movements Back listener, and refreshes journey source references.

Changes

Script budget checks and reports

Layer / File(s) Summary
Inherited overage policy
scripts/check-script-budget.mjs, tests/ward-ci-budget-heal.test.ts, docs/ward-flow/PUBLIC-CI.md
Inherited growth now has a fixed overage ceiling, while measurements no larger than main pass. Tests cover unchanged over-budget measurements and growth beyond the ceiling.
Report-only route asset measurements
scripts/check-script-budget.mjs, tests/ward-script-budget.test.ts, docs/ward-flow/PUBLIC-CI.md
The script measures scripts, stylesheets, and preloads across budgeted and extra routes, formats results, and writes the report to configured outputs. Report failures do not change the budget verdict.

Inbox malformed-ID handling

Layer / File(s) Summary
Inbox ID guards and source records
src/components/ward-management/ward-inbox-reducer.ts, src/components/ward-management/ward-audit.ts, tests/ward-inbox-acknowledge-malformed.test.ts, docs/ward-flow/journey/MAP-INVENTORY.md, docs/ward-flow/journey/actions.json, docs/ward-flow/journey/event-dispositions.json, docs/ward-flow/journey/machines.json
Inbox reducer actions and audit processing treat non-string IDs as blank instead of calling .trim() on them. Tests check rejection behavior, and journey records update source references and hashes.

Governance review history

Layer / File(s) Summary
Review history lookup and integration
src/components/ward-management/governance-review-history.ts, src/components/ward-management/governance-registers.tsx, tests/ward-governance-review-history.test.ts, docs/ward-flow/journey/actions.json
A lookup indexes reviews by generation and event ID. GovernanceSession uses it and copies the selected event history; tests check matching, ordering, and single-pass iteration.

Movements Back handling

Layer / File(s) Summary
Stable popstate listener
src/components/ward-management/movements/movements-screen.tsx, tests/ward-movements-popstate-listener.dom.test.tsx
The popstate handler checks the latest movements without re-registering its listener when the array changes. Tests check listener count and drawer restoration.

Full details: Title check

Explanation

The title accurately identifies the main changes: budget tolerance limits, size reporting, render updates, and inbox refusal handling. It is somewhat long but remains specific and related to the changeset.

Full details: Generated And Sensitive Files

Explanation

The PR adds no secret or prohibited local artifact. The changed journey explorer is an intentionally tracked generated document. Its changes update source references and build metadata for the modified code; the journey README documents the generated page.

Full details: Risky Git Or Deployment Actions

Explanation

The PR introduces no risky Git or deployment actions. The budget script changes report sizes, and the documentation describes that report. The generated journey changes update source references and metadata.

Full details: Supabase Project And Schema Safety

Explanation

The PR does not change Supabase project references, migrations, RLS, or database policies. The code changes address budget reporting, UI rendering, and malformed inbox IDs. The journey documentation changes update source references and digests.

Full details: Runtime And Package Manager Integrity

Explanation

The PR does not change package-manager, lockfile, engine, or CI runtime settings. package.json retains Node 24 and npm 11 requirements, and .npmrc retains engine-strict=true. The script changes do not introduce dependency-resolution flags or a different runtime requirement.

Full details: Verification Claims

Explanation

The PR description claims that 18 inbox/audit reducer suites passed, but does not identify the files or the exact check. It also reports “lint: clean” for changed files and “CI contracts: OK” without identifying the exact checks. The repository has multiple lint and CI-contract scripts, so those labels do not establish which checks ran.

Resolution

For each claim, name the exact command or check and its result. Identify the 18 test files or the command that selected them. If a check was not run, state that and give the reason.

Full details: Docstring Coverage

Explanation

Docstring coverage is 50.00% which is insufficient. The required threshold is 70.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 14 functions across 11 files. (5 skipped: 5 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

The perf-audit edits to ward-inbox-reducer.ts and governance-registers.tsx
left the journey source reviews stale, so the static checks refused to build
the explorer. Behaviour is unchanged (a non-text inbox id is now refused like
a blank one; review history lookup is memoised), so only the digests and the
shifted line references move. Regenerated outputs with verify.mjs --write.

- Permission matrix: the inbox events no longer throw on a bare event, so
  the engine now answers those cells itself; regenerated
  docs/ward-flow/permission-matrix.md (unit shard 4 failure).
- Size report: intersect each budgeted page's scripts before its asset
  downloads, and omit the shared-shell total when a budgeted page cannot
  be read, so the total never covers only some pages.
- Inbox: RELEASE_INBOX_ITEM_OWNERSHIP and UNSNOOZE_INBOX_ITEM refuse a blank
  or non-text id before reading any history, so a blank-keyed restored
  history cannot be released or returned. Journey notes and the reviewed
  ward-inbox-reducer.ts digest updated to match.
- Movements Back test: switches scenario after mount and checks Back opens
  a newly present movement and refuses one that has gone.

CI on 908f3fc: browser setup now passes because #1631's mirror-free install has been ported. The two release gates still fail, and those failures are not from this PR. They also show up on #1630 and #1606, which are built on main 51a4745, with the same shift value.

  • Phone gate: the "Transfer with transport" journey (tests/release-gate-journeys.spec.ts:236) times out waiting for the phone menu's "All wards" link to become stable.
  • Desktop gate: the home page / fails the layout-shift check (tests/release-gate-axe-sweep.spec.ts:517) with a CLS of 0.1339.

The fix is being made on main in a separate change. Once it lands, I'll merge main into this branch. Auto-merge stays armed.
