User description

Summary

Fixes#591 and #593 — two real, independent bugs in ensureWelcomePortalEntry()'s Factory-Reset recovery flow, both root-caused via the actual Playwright trace/accessibility-snapshot/console-log artifacts from CI runs during this PR's own convergence.

Bug 1 — #591: stale view-carrying URL survives the reset reload

ensureWelcomePortalEntry()'s Factory-Reset recovery flow necessarily navigates to Settings before triggering the reset. Ordinary in-app navigation writes #/settings into the URL hash via pushHash(). wipeAllAppData()'s final window.location.reload() preserves that same URL, and useApp.ts's readInitialView() reads the hash (then the view query param) with higher priority than checking whether a project even exists — so a genuinely successful wipe could still reboot straight back into Settings.

Fix:sanitizeViewCarryingUrlState() strips the hash and the view query param via history.replaceState immediately before the real reload. (A follow-up Cubic finding on this fix was also addressed — see below.)

Bug 2 — #593: visibilitychange flush races the reset's own reload

After #591's fix, a different symptom appeared at the same final assertion: the app landed on the Dashboard with a synthetically-seeded placeholder project instead of the WelcomePortal. Traced via console-log timeline evidence (no project-rehydration message after the reset+reload, ruling out an IDB-deletion race) plus source tracing of index.tsx's boot sequence:

index.tsx's visibilitychange handler (and the desktop quit-flush, and register-sw.ts's update flush — all three funnel through flushPersistedState()) fires on window.location.reload() itself, since a reload triggers visibilitychange before the page actually unloads.
wipeAllAppData() doesn't stop the running app or its listeners during the 300ms settle window before that reload, so this flush can reopen and repopulate the IndexedDB database it just deleted with the stale, pre-reset in-memory Redux state.
Settings appears to survive (a write far enough along to commit before the unload) while the project usually doesn't (interrupted first, later in the same Promise.allSettled) — producing exactly the "settings-only persisted state" shape that makes index.tsx's isNewUser = !preloadedState evaluate false and skip the WelcomePortal, landing on the Dashboard instead, where useProjectBootstrapEffect then seeds a placeholder project title into the always-non-null default Redux project shell.

Confirmed independent of PR #583's IDB reset-gate architecture in mechanism (this closes one specific persistence-during-reset race with a minimal flag; #583 builds a general-purpose admission/generation/fail-closed gate for every long-lived connection) but the same class of problem — when #583 rebases, this invariant needs to be preserved inside its hardened reset implementation, not reintroduced separately.

Fix:isFactoryResetInProgress() is set before any wipe work starts and guards flushPersistedState() itself, so all three call sites are protected by one change. Resets back to false if the reset itself fails and never reloads, so a failed attempt doesn't silently block every future save for the rest of the session.

Bug 3 (review finding) — reserialization of unrelated query state

A Cubic P3 finding on the original #591 fix was valid: url.searchParams.delete('view') followed by reading url.search back reserializes every retained query parameter via URLSearchParams.toString(), not just the one being removed — e.g. turning a raw %20 into +, or a bare flag ?foo into ?foo=. Replaced with a string-level stripViewQueryParam() that removes only the view key, leaving every other parameter's raw encoding untouched. Verified against URL/URLSearchParams semantics directly (not assumed) before implementing.

Non-goals

Does not touch hooks/useApp.ts's deep-link priority order or services/deepLinkService.ts.
Does not import or reimplement any part of PR fix(e2e): eliminate WelcomePortal startup/navigation nondeterminism (#532) #583's reset-gate architecture.
Does not increase any E2E timeout or Playwright retry count.

Test plan

pnpm run lint — pass
pnpm run typecheck — pass (exact CI command)
pnpm exec vitest run tests/unit/factoryResetService.test.ts tests/unit/persistedStateFlush.test.ts tests/unit/registerSwUpdateFlush.test.ts — 27/27 pass, including new regression tests for both bugs and the query-encoding fix
pnpm run ci:prepush — pass
Full GitHub CI, including a genuine first-attempt, zero-Playwright-retry Chromium + Mobile Chrome pass on onboarding-entry-precondition.spec.ts (no rerun-only acceptance, per this repo's standing bar for E2E-nondeterminism fixes)

Summary by Sourcery

Make factory-reset recovery deterministic by clearing stale navigation state and preventing background persistence from recreating data during the reset.

Bug Fixes:

Make factory reset reliably reopen the app on a clean Welcome screen instead of restoring stale view state or repopulated data.
Prevent persistence and indexing writes from racing factory reset and recreating deleted state.
Restore normal persistence after a failed reset without leaving writes permanently blocked.

Enhancements:

Preserve unrelated URL query parameters exactly while removing only the view state used for navigation recovery.
Ensure post-save indexing and analytics writes are tracked and completed before reset cleanup.

Tests:

Add regression coverage for reset write races, URL sanitization and encoding preservation, failed-reset recovery, and awaited index writes.

Chores:

Update documented test counts to reflect the expanded test suite.

Summary by CodeRabbit

- Factory reset clears view-specific URL state while preserving unrelated URL parameters.
- Failed reset operations no longer reload the application and correctly report the failure.
Documentation
- Updated README test metrics to reflect 7,368+ tests across 595 files.
Tests
- Expanded coverage for reset progress, failed resets, URL sanitization, pending writes, race conditions, and paused persistence.

CodeAnt-AI Description

Make factory reset finish cleanly and reopen as a fresh install

What Changed

Factory reset now waits for pending saves and search or analytics updates before deleting app data.
Saves triggered during reset, including reload-related flushes and delayed autosaves, are skipped so deleted data is not recreated.
Reset removes the previous view from the URL before reloading, including encoded view parameters, while preserving unrelated URL parameters.
Failed desktop resets clear the reset state so normal saving can resume without reloading.
Added coverage for reset races, URL cleanup, pending writes, and post-reset save behavior.

Impact

✅ Factory reset opens the Welcome screen
✅ Deleted data is not recreated during reset
✅ Failed resets leave saving available

Reviewer's Guide

The factory-reset flow now removes deep-link state that would otherwise survive a full reload and take a successfully wiped app back to its pre-reset view, with focused ordering and preservation regression coverage.

Invoke sanitization after reset cleanup and delay, directly before `window.location.reload()`. Keep sanitization failures from blocking the reset flow.	`services/factoryResetService.ts`
Add regression coverage for reset URL sanitization and update documented test counts.	Verify hash and `view` state are removed, unrelated URL state is retained, and history replacement precedes reload. Update README test-count references for the added test.

PR Summary

Updating Test Count Details in README
The count of tests reflected in the README document has been increased slightly from its previous number. This new value is also being updated in various sections within the document.
New Function for Sanitizing URL
A new function, sanitizeViewCarryingUrlState, has been added that cleans the URL before the application reloads. It specifically removes certain parts from the URL like the view query parameter and hash.
Enhanced Data Wiping Function
Updates have been made to the wipeAllAppData function to utilize the new sanitizeViewCarryingUrlState function before the application reloads. This ensures that URL is cleaned properly, preventing redundancy.
Testing for New Function
A test case has been added to verify the correct operation of the new function sanitizeViewCarryingUrlState. The test ensures that the function efficiently removes the view parameter while retaining the necessary query parameters in the URL.
Improved Readability in Coding
For improved readability, the regular expression constants used in the factoryResetService.ts file have been restructured. This has been achieved by separating the expressions into various lines rather than having them in a single, potentially confusing, line.

This PR correctly fixes the factory-reset URL state bug described in issue #591. The implementation is clean and well-tested.

Changes Reviewed:

factoryResetService.ts: Added sanitizeViewCarryingUrlState() to strip hash and view query parameter before reload, fixing the bug where reset would redirect back to the pre-reset view
factoryResetService.test.ts: Added comprehensive regression test verifying URL sanitization happens before reload and preserves unrelated URL state
README.md: Updated test count badges (7357+ → 7358+)

Strengths:

The fix is correctly positioned in the execution flow (after IDB/cache clearing, before reload)
Test coverage includes call order verification to ensure sanitization precedes reload
Edge cases are properly handled (try-catch prevents URL sanitization from blocking reset)
The regex-based cache filtering and Tauri data clearing remain unchanged and correct

No blocking issues found. The implementation aligns with the PR description and successfully addresses the root cause where readInitialView() reads URL state before checking project existence.

📝 Walkthrough

Walkthrough

Factory reset now tracks active cleanup, drains pending persistence, removes view-carrying URL state before reload, and blocks persistence during reset. Tests cover reset state, URL handling, cleanup failure, and persistence suppression. README metrics now report 7,368+ tests.

Changes

Factory reset lifecycle

Layer / File(s)	Summary
Reset lifecycle and URL sanitization `services/factoryResetService.ts`, `tests/unit/factoryResetService.test.ts`	Factory reset drains project, settings, and background writes before deletion, tracks progress, sanitizes hash and literal or encoded `view` query state, reloads after cleanup, and clears progress on failure. Tests cover these behaviors.
Persistence suppression during reset `app/persistenceCoordinator.ts`, `app/persistedStateFlush.ts`, `app/listenerMiddleware.ts`, `tests/unit/persistedStateFlush.test.ts`, `tests/unit/listenerMiddleware.test.ts`	Persistence flushing and debounced listeners stop during factory reset. Project autosave rechecks reset state before enqueueing, and background index and analytics writes use a dedicated coordinator. Tests cover active-reset and race-condition cases.

Project metadata and workflow test updates

Layer / File(s)	Summary
Update test metrics `README.md`	README badges, testing details, project structure, and CI metrics now report 7,368+ tests across 595 test files.
Workflow test helper cleanup `tests/unit/tooling/*`	Workflow policy tests use escaped template literals for GitHub expressions, a typed failure import, and reformatted fixtures and assertions. Test behavior remains unchanged.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk:🟡 Moderate · up to 02127

Overlapping saves can leave cross-project indexing on older project data. Separate the two background queues before merge.

…listeners The isFactoryResetInProgress() guard on flushPersistedState() (previous commit) only closed the visibilitychange/quit-flush race. Two OTHER onboarding-entry-precondition.spec.ts tests (unrelated to the Spanish- locale scenario the first fix targeted) still hit the identical #593 symptom on this PR's own discriminator CI run -- confirmed via the same trace-forensics method (no project-rehydration log after the reset, Dashboard rendered instead of the WelcomePortal). Root cause: app/listenerMiddleware.ts's own 1s-debounced project/ settings autosave listeners write directly via storageService, entirely bypassing flushPersistedState(). A debounce armed by a state change just before the Factory Reset navigation began (e.g. entering Settings) is still pending when wipeAllAppData() starts, and fires ~1s later -- inside or just past the reset's own delete-then-reload window -- repopulating the database the reset just deleted. Added the same isFactoryResetInProgress() check to addDebouncedListener itself (the shared factory every auto-save/auto-track listener in this file is built on), so project autosave, settings autosave, and codex auto-tracking are all protected by one change, the same way the prior fix centralized the flushPersistedState() call sites.

…key comparison, fix test mock leak Addresses 5 review findings on PR #592 (2 duplicate-root-cause pairs + 1 test-hygiene issue), all verified against current source before fixing: 1. CodeRabbit + Cubic (duplicate): a save enqueued via projectPersistenceCoordinator/settingsPersistenceCoordinator just before resetInProgress flips has already passed its own guard check and runs regardless -- isFactoryResetInProgress() only stops a save from *starting*, not one already in flight. wipeAllAppData() now awaits both coordinators' idle() immediately after setting the flag, before any deletion work begins, so an already-in-flight save finishes first instead of racing deleteAllIndexedDBDatabases() (or, on desktop, clearTauriAppData()). 2. Cubic + CodeRabbit (duplicate): stripViewQueryParam() compared the raw query key to 'view', but useApp.ts's readInitialView() reads via URLSearchParams.get('view'), which decodes -- an encoded spelling like ?%76iew=settings survived the filter and could still restore Settings after reload. Added isViewKey() to decode each key before comparing (falling back to the raw comparison if decoding throws), while still preserving every other parameter's raw text untouched. 3. Cubic: the new listenerMiddleware reset-guard test set mockIsFactoryResetInProgress to true and reset it back to false on the test's own last line -- an assertion failure partway through would leave every later test in the file silently skipping its debounced saves. Moved the reset into the top-level beforeEach instead, alongside the existing vi.clearAllMocks().

…tspot gate CodeScene's Prevent-Hotspot-Decline gate flagged runPostProjectSaveSideEffects() itself as a Complex Method on commit 7756dc4 -- the prior CodeFactor-driven extraction moved both the cross-project-index update and the DuckDB dual-write into one function, and CodeScene's complexity delta on that hotspot file (app/listenerMiddleware.ts) tripped on the combined branching. Split into two single-purpose functions, runCrossProjectIndexUpdate() and runDuckDbDualWrite(), each an early-return guard over its own concern. runPostProjectSaveSideEffects() now just calls both in sequence -- same fire-and-forget timing as before (indexProject's own call is still not awaited, only the dynamic import that precedes it), no behavior change.

Round update (head 99d8f139):

Pushed two commits since the last update:

7756dc44 — fixed the 3 outstanding review findings: saving-status left stuck on a failed-then-non-reloading reset (Cubic), CodeFactor's Complex-Method finding on the TOCTOU-fix commit (extracted runPostProjectSaveSideEffects()), and a test-isolation leak in factoryResetService.test.ts (Cubic). All 3 threads replied-to with the fix commit and resolved.
99d8f139 — CodeScene's Prevent-Hotspot-Decline gate then flagged the extracted runPostProjectSaveSideEffects() itself as a new Complex Method (expected churn from fixing one bot's complexity finding into another's threshold). Split it into runCrossProjectIndexUpdate() and runDuckDbDualWrite(), each a single-purpose early-return guard. No behavior change — same fire-and-forget timing as before.

CodeRabbit's bracketed [Grund / Impact / Kreativer Mehrwert] QNBS-v3 format request was verified against this repo's actual convention and rejected as a hallucinated guideline (replied + resolved, not implemented).

Local validation on 99d8f139: lint clean, typecheck clean (exact CI command), 45/45 targeted tests green (listenerMiddleware.test.ts + factoryResetService.test.ts), full ci:prepush PASS. 0 unresolved review threads. Waiting on the fresh CI wave on this head before re-evaluating merge readiness.

[check-pr-size] PR size is over the hard tier (normal profile): 12 files, 633 meaningful lines, 11 commits — limit ≤20 files / ≤1200 lines / ≤10 commits. Consider splitting into smaller, independently reviewable PRs.

cubic (P1, confidence 9) found that projectPersistenceCoordinator's enqueue() resolving already clears its own active/queued slot the moment the project save itself completes -- so a factory reset starting right after that point sees the coordinator as idle and proceeds straight to deleting IndexedDB databases, while the post-save cross-project-index update and DuckDB dual-write (fired as fire-and-forget background work, per the existing non-critical/best-effort design) are still in flight and completely untracked by any drain. A write landing after deletion recreates the exact database the reset just wiped, reintroducing the stale-state-survives-reset bug class this PR exists to close. Root-caused via the same admission-boundary trace used for the earlier project-autosave TOCTOU fix in this PR, then closed with the same pattern rather than a bare guard: - New backgroundWriteCoordinator (app/persistenceCoordinator.ts) — a second PersistenceCoordinator instance, deliberately separate from projectPersistenceCoordinator so a slow non-critical index/analytics write can never queue behind (and delay) the next actual project save. - Both runCrossProjectIndexUpdate() and runDuckDbDualWrite() now re-check isFactoryResetInProgress() with zero await before registering their write with backgroundWriteCoordinator.enqueue() -- closing the window where a reset starts during their own dynamic-import/loader await, mirroring the project-autosave path's existing double-check. - wipeAllAppData() now drains backgroundWriteCoordinator alongside the existing two coordinators before any IndexedDB deletion starts. Added a deterministic regression test in factoryResetService.test.ts (drains a still-pending background write before deleting any database, mirroring the existing project-save drain test) plus two listenerMiddleware.test.ts tests covering the guard directly: the reset-after-save-resolves race, and the normal (non-reset) path still registers the write.

…ate literal Biome's useTemplate rule kept flagging the string-concat form as an info, and its own 'unsafe fix' suggestion (a bare `${{ ${expr} }}` template literal) is actually a JS SyntaxError -- verified directly with node -e, confirming the prior code comment's claim. The real fix uses a backslash- escaped dollar (`\${{ ${expr} }}`) so only the inner interpolation is live; verified it produces exactly '${{ github.sha }}' and that both targeted suites (74 tests total) still pass unchanged. No suppression, no disabled rule, no semantic change -- 'pnpm run lint' now reports zero warnings/errors/infos.

Round update (head 02127ad8):

Two more commits:

e2c77276 — fixed a genuine P1 finding (cubic, confidence 9; independently also raised by CodeRabbit, auto-resolved as a duplicate once this landed): projectPersistenceCoordinator.enqueue() resolving already clears its own active/queued slot the instant the project save completes, so wipeAllAppData()'s drain saw the coordinator as idle immediately after — while the post-save cross-project-index update and DuckDB dual-write (fire-and-forget, non-critical by design) were still in flight and completely untracked by any drain. Fixed with a new, deliberately separate backgroundWriteCoordinator (so this non-critical work never delays the next real project save), a re-check of isFactoryResetInProgress() at each write site mirroring the existing project-autosave double-check, and a third coordinator drained in wipeAllAppData(). Added a deterministic regression test plus two direct guard tests. cubic's companion P3 finding (split runPostProjectSaveSideEffects further) was auto-resolved as a duplicate of the CodeScene split already done in 99d8f139.
02127ad8 — unrelated tiny lint-noise cleanup requested directly: replaced the string-concatenation githubExpression() test helper (duplicated in two tooling-policy test files) with a template literal using an escaped \$ — verified the naive unescaped form Biome's own autofix suggests is actually a JS SyntaxError (confirmed with node -e), and that the escaped form produces the exact same output. pnpm run lint now reports zero warnings/errors/infos, down from 2 pre-existing infos.

0 unresolved review threads (12 total, all resolved). Local validation: lint clean (0 issues), typecheck clean, 122/122 targeted tests green, full ci:prepush PASS. Waiting on the fresh CI wave on this head.

…s DuckDB mirror Two independently-confirmed findings on the previous commit's fix, both verified against current source before acting: 1. CodeRabbit (major) and cubic (P2, confidence 9) both flagged that backgroundWriteCoordinator's single enqueue()'d queue slot was shared between two unrelated resources -- cross-project indexing and DuckDB dual-write. Since enqueue() replaces (not appends to) whatever sits in the queued slot, a busy save cycle could let a later DuckDB enqueue silently discard an earlier, still-pending index-update enqueue (or vice versa) -- unlike projectPersistenceCoordinator, where discarding an older *version of the same save* is fine, discarding one of two *different* resources' writes just because they share a coordinator is a genuine data-loss bug, not intentional supersession. Split into two dedicated instances, crossProjectIndexCoordinator and duckDbWriteCoordinator, so neither can starve the other. 2. cubic (P1, confidence 10): indexProject() itself fire-and-forgets its internal DuckDB cross-project mirror write (void loadDuckdbAnalytics().then(...)), so its own returned promise resolves right after the IDB put -- before the mirror write finishes. Routing the outer call through a coordinator doesn't help when the function's own promise doesn't represent the full operation. Changed void to await inside indexProject() (its only call site already treats it as fire-and-forget at the listener level, so this is safe) so a caller draining indexProject()'s promise -- like a factory reset -- genuinely waits for the mirror write too. Updated the coordinator drain test to prove wipeAllAppData() waits for BOTH coordinators independently (resolving only one is not enough). Added a deterministic test on indexProject() itself proving its promise doesn't settle until the DuckDB mirror does. Removed the now-redundant flushMicrotasks() helper in crossProjectIndexService.test.ts -- awaiting indexProject() already covers what it used to manually flush for.

qnbs · 2026-09-03T10:45:39Z

Round update (head 5883237f):

Two more genuine findings on the previous fix, both verified against current source before acting:

CodeRabbit (major) + cubic (P2, confidence 9) — duplicate root cause: backgroundWriteCoordinator's single queued-slot design meant a later DuckDB enqueue could silently discard an earlier still-pending index-update enqueue (or vice versa), unlike projectPersistenceCoordinator where discarding an older version of the same save is intentional — discarding one of two different resources' writes because they share a coordinator is data loss, not supersession. Split into crossProjectIndexCoordinator and duckDbWriteCoordinator.
cubic (P1, confidence 10) — confirmed at the source: indexProject() itself fire-and-forgets its internal DuckDB cross-project mirror write, so its own promise resolved right after the IDB put, before the mirror settled. Changed that internal call from fire-and-forget to awaited (safe — its only call site already treats the outer call as fire-and-forget at the listener level).

Added: a test proving wipeAllAppData() waits for both coordinators independently, and a deterministic test on indexProject() proving its promise doesn't resolve until the mirror write does.

Also confirmed the E2E flake on the previous head (a11y.spec.ts, WCAG color-contrast, chromium) is unrelated to this PR — onboarding-entry-precondition.spec.ts itself showed 0 failures and zero retry attributes on both browsers in that same run; the contrast issue is pre-existing and already tracked as the separate future item #565.

0 unresolved review threads. Local validation: lint clean, typecheck clean, 71/71 targeted tests green, full ci:prepush PASS. Waiting on the fresh CI wave on this head.

…test cubic (P2, confidence 8) correctly pointed out the drain test's middle assertion couldn't actually detect a dropped crossProjectIndexCoordinator drain: resolving the index write first left the DuckDB write still pending regardless, so deletion stayed blocked whether or not the index coordinator was even included in wipeAllAppData()'s Promise.all -- the test would still pass if that coordinator were silently removed from the drain. Reordered to resolve DuckDB first: with every other awaited promise already settled at that point, an omitted index-coordinator drain would let deletion proceed immediately, which the assertion now catches.

qnbs · 2026-09-03T11:15:56Z

Round update (head cf1e5e3b):

One more finding, verified valid: cubic (P2, confidence 8) correctly pointed out the coordinator-drain test's middle assertion couldn't actually detect a dropped crossProjectIndexCoordinator drain — resolving the index write first left the DuckDB write still pending regardless, so deletion stayed blocked whether or not the index coordinator was even wired into wipeAllAppData()'s Promise.all. Fixed by reordering to resolve DuckDB first, which is the actually-discriminating case.

0 unresolved review threads. Lint clean, ci:prepush PASS, targeted suite (14/14) green. Previous head (5883237f) already had a fully clean CI wave: all checks green including codecov/patch, and onboarding-entry-precondition.spec.ts genuinely first-attempt zero-retry on both browsers (123 passed, no flaky line at all this run). Waiting on the fresh CI wave for this head before re-checking merge readiness.

… check-pr-size.mjs exception-ceiling bug Recomputed entirely from a genuine rebase of #583 onto current main (which now carries #562, #592, and #594) rather than trusting the historical 70 files / 1753 lines / 21 commits figures the earlier commits on this branch carried forward. The rebase itself revealed two things the prior estimate could not have known: 1. #583 and #592 (the independent factory-reset persistence-admission fix, issues #591/#593) touch overlapping files -- app/listenerMiddleware.ts, services/factoryResetService.ts, services/crossProjectIndexService.ts, and their tests. Reconciled by layering both mechanisms inside wipeAllAppData(): #592's isFactoryResetInProgress()/coordinator-draining gate runs first (blocks new Redux-listener writes, drains in-flight ones), then #583's beginIdbReset() force-closes every other long-lived IDB connection the coordinators do not track. 2. PR #590 (merged earlier, unrelated) had already independently shipped the same locale-independent Settings/mobile-"More"-button navigation fix#583 originally introduced across five files (components/SettingsView.tsx, components/settings/SettingsModals.tsx, components/settings/DataSection.tsx, components/Sidebar.tsx, tests/e2e/helpers.ts). Parallel convergent evolution left #583's own changes to those files fully superseded -- zero net diff against current main -- so they are correctly absent from allowedPaths. Final measured diff: 65 governed files (84 incl. generated locale bundles), 1611 meaningful lines, 14 commits -- exact ceilings, no speculative headroom, computed directly via check-pr-size.mjs itself against the real rebased branch. That direct measurement also surfaced a latent bug in check-pr-size.mjs: when an exception's own ceiling legitimately exceeds TIERS.absolute (30 files/3000 lines/15 commits) -- the entire point of granting one -- evaluatePrSize() fell through to selectSeverity() against that fixed tier instead of treating the exception's own ceiling as authoritative, so a fully-satisfied wide exception still reported blocking:true. Neither #539 (maxFiles:30, at the absolute tier's own boundary) nor #564 (maxFiles:3, well under it) had ever exercised this path -- #583 is the first exception whose own scope is wide enough to expose it. Fixed to short-circuit on exception.entry directly, verified against a synthetic base commit carrying this fix plus the recomputed entry, diffed against the actual rebased #583 branch (exit 0, PR_SIZE_EXCEPTION=APPLIED). Added a regression test covering a wide exception ceiling that exceeds the fixed absolute tier. Squashes the prior five commits on this branch (four incremental "recompute" attempts plus a stray temp commit), none of which had been verified against a real rebase or the actual gate behavior.

* chore(release): bump version to v1.28.4 Patch release reconciling release-truth documentation with everything merged to main since v1.28.3 (62 commits / ~40 PRs, audited against live GitHub state, not assumed from commit subjects): - fix: PWA first-install unprompted reload (#585, PR #613) - fix: shared-origin service-worker cache-read isolation (#514, PR #612) - fix: Factory Reset could reboot into Settings instead of Welcome Portal (PR #592) - fix: preserve-first desktop corruption recovery (PR #542) and a distinct filesystem-I/O recovery action (PR #545) - fix: intentionally cleared project metadata no longer reappears (PR #546) - a11y: Welcome/Home dashboard WCAG AA contrast + reduced-motion cascade fix + default appearance preset change (#565, PR #609); ManuscriptEditor contrast (PR #560) - security: fflate ZIP64-parsing DoS override (PR #595); routine dependency floor bumps (PR #587, #561, #562, #594) - docs: R-15 secure desktop storage design contract admitted (PRs #564, #580, #581, #582, #584) — design only, no implementation yet - tests: visual regression testing repaired — baselines were directory listings, not the application (PR #610); IDB reset-quiescence hardening (PR #596); WelcomePortal E2E navigation made locale-independent (PR #590) Everything classified as pure internal/CI-governance churn (PR-size exception plumbing, dual-graph tooling, toolchain pins) is omitted from CHANGELOG.md as non-user-facing. Version bumped via the existing sync scripts (sync-tauri-version.mjs, sync-sw-version.mjs) across package.json, src-tauri/Cargo.toml, src-tauri/tauri.conf.json, src-tauri/Cargo.lock, AGENTS.md, and public/sw.js's APP_VERSION. CHANGELOG.md and README.md use the established release-candidate marker convention () so the dated entry and version badge are truthful before the v1.28.4 tag exists; both markers are removed in a follow-up post-release truth-sync once the tag and GitHub Release are published, matching the v1.28.2/v1.28.3 precedent. TODO.md's Current Sprint section was archived (its final "release cut remains open" bullet is now resolved — v1.28.2 and v1.28.3 both shipped) and replaced with the actual current sprint: this release cut followed by the R-15 desktop at-rest encryption priority program. AUDIT.md is intentionally not touched here — its release-gate entry requires real post-merge CI/CodeQL run evidence that doesn't exist until after this PR merges and the tag is cut, matching how every prior release's AUDIT.md entry was written (a follow-up commit, not part of the release-prep PR itself). * docs(release): correct premature done-marker on the v1.28.4 TODO item TODO.md's Current Sprint marked the release cut as done (checked 'v1.28.4' release cut, reconciling ... AUDIT.md truth ...) while this same PR's own Non-goals section correctly states AUDIT.md is not touched here, and while no tag, GitHub Release, or release artifacts exist yet. Corrected to in-progress language naming PR #615 directly and listing what actually remains pending (tag, release, artifacts, post-release AUDIT.md evidence). * docs(release): correct R-15 gate language and credit PR #596's real fix Two corrections from review, verified against live evidence before fixing: 1. TODO.md's Current Sprint claimed R-15 desktop at-rest encryption implementation was being prioritized now. docs/native/DESKTOP- MIGRATION-ROADMAP-REV3.md explicitly forbids pulling Wave 3/4 R-15 implementation ahead of unresolved Wave 2 authority prerequisites, and CORE-MIGRATION-LEDGER.md row 10 records S5_IMPLEMENTATION_READY=NO. Corrected to state R-15 design is complete but implementation stays gated behind the still-open Wave 2 prerequisite (ledger row 9: the project state-shape compatibility adapter), which is what this sprint's desktop-storage work actually is. 2. CHANGELOG.md listed PR #596 only as generic IDB test hardening under Tests. Verified against its actual diff: deleteDatabase() previously resolved on a genuine onerror or an onblocked event as if deletion succeeded, so wipeAllAppData() could report Factory Reset complete while a database was never actually deleted. onerror now rejects; onblocked waits for the connection to close before giving up. This is a real production data-integrity fix, not test hardening, and now has its own Fixed entry.
