Reviewer's GuideThis PR removes WelcomePortal startup and factory-reset nondeterminism by coordinating all IndexedDB teardown through a fail-closed generation/epoch gate, preventing or invalidating opens that overlap resets, making database deletion ownership-safe and fully awaited, and adding recovery UX plus comprehensive race-focused tests; it also updates the associated localization artifacts and README metrics.

This PR implements a comprehensive IDB reset-quiescence system to eliminate WelcomePortal startup/navigation nondeterminism in E2E tests. The implementation is thorough and well-architected.
Summary:
The core idbResetGate.ts module provides generation-based tracking to prevent stale connections from being cached after a reset, combined with a fail-closed barrier that ensures all connection closers complete before database deletion proceeds. The integration across 9 service modules and coordination with persistence draining shows careful attention to race conditions.
Key strengths:
- Fail-closed semantics:
beginIdbReset()rejects if any closer fails, preventing destructive deletion on unproven teardown - Generation/epoch invariant prevents stale opens from becoming authoritative after a reset
- Comprehensive registration:
IdbConnectionManagerauto-registers subclasses, and per-projecty-indexeddbproviders dynamically register/unregister - Late-joiner barrier: closers registered mid-reset join the current awaited barrier instead of racing ahead
- Proper error aggregation using
Promise.allSettledin both reset gate and database deletion - Test coverage validates the critical invariants
Code quality:
The implementation is production-ready with no blocking defects found during review. The test suite validates the complex concurrent scenarios, and the documentation clearly explains the fail-closed contract and generation-checking protocol.

Tip: instead of fixing issues one by one fix them all with cubic
Re-trigger cubic
PR #583 could not be reopened after its branch was force-pushed during the size recompute -- GitHub permanently blocks reopening a closed PR once its head branch has been force-pushed or recreated. PR #596 was opened from the identical branch/commit as #583's successor; this updates the pr-size-exceptions.json entry's prNumber (and id) to match so check-pr-size.mjs's identity match applies to the live PR. No other figures in the entry change.
…commit (#598) #596's live review surfaced three genuine gaps in files already inside its exception scope, fixed by amending its last commit (preserving the 14-commit ceiling) rather than adding a 15th. That pushed the measured meaningful-line count from 1611 to 1741; maxFiles and maxCommits are unchanged, and no path outside the existing allowedPaths was touched.
…eview - listenerMiddleware.ts: encryption-disable is now symmetric with the encryption-enable branch already handled -- a handle that chose the shared NOOP_PERSISTENCE singleton because encryption was ready is discarded once encryption is later disabled, so local-first sync resumes durable persistence instead of staying memory-only forever. - aiInferenceCacheService.ts: the reset closer now clears openPromise too (identity-checked, matching crossProjectIndexService.ts's established pattern), not just db -- a caller made before the stale in-flight open settles now starts a fresh attempt instead of reusing the invalidated one. - idbResetGate.ts: a concurrent beginIdbReset() call now joins the already-draining barrier instead of overwriting activeBarrier -- a closer that registers during the overlap window no longer risks being orphaned into a barrier only the second caller awaits, which could let the first caller proceed into deletion before that closer's teardown actually finished. Also retained from the prior commit: the earlier fix added destroy()/clearData() to the mocked NOOP_PERSISTENCE and persistProjectDoc() return value (a real type-fidelity gap), but claimed in its own comment that this let tests assert teardown was actually invoked while no test did. Adds that assertion for the one mock actually exercised (mockNoopDestroy, via the OFF-transition warmup teardown), and simplifies the other three back to plain no-op closures rather than stable mock references nothing asserts on.

…nce (#601) Four independent timeout-cancellations occurred within ~2 hours of CI activity across two different jobs, all traced to the same root cause: the shared ./.github/actions/setup composite (pnpm install --frozen-lockfile, with pnpm-store caching already configured) took 7+ minutes on affected runs instead of its typical ~1-2 minutes -- consistent with this repo's already-documented npm-registry/CDN edge-node variance (the same class of issue noted for `pnpm audit`'s decode failures), not a caching misconfiguration or a code regression. Direct evidence (job step timestamps, both confirmed independently): - Security Audit (2026-09-04, commit c0f372b first attempt): setup 00:24:06-00:31:28 (7m22s), leaving pnpm audit only until the 10-minute job timeout before OSV scan / gitleaks / dependency-review never got to run at all. - Quality Gate Node 22 (PR #596, second consecutive attempt): setup 00:47:10-00:54:37 (7m27s), leaving Vitest cut off by the 15-minute job timeout mid-run even though lint/typecheck/other gates all passed in the remaining ~11 seconds. - Separately, Quality Gate Node 24 succeeded at both 9m17s and 14m7s on different runs of otherwise-identical content -- a 50%+ swing from runner/network variance alone. security: 10 -> 15 minutes. quality: 15 -> 22 minutes. Both sized to comfortably absorb a slow (~7-8 min) setup stacked with a normal-length run of the job's own real work, without weakening or skipping any test, lint, or security gate.
…532) Root-causes and fixes two confirmed, independent defects behind the recurring onboarding-entry-precondition.spec.ts / a11y.spec.ts flake class, plus a related data-integrity bug found while investigating: 1. Playwright addInitScript persistence bug (confirmed root cause). ensureWelcomePortalEntry() used page.evaluate() to force English before its Settings -> Data & Backups -> Factory Reset recovery navigation, then called page.reload(). Per Playwright's documented behavior, any addInitScript registered by the calling test (e.g. the non-English-language test seeding 'es') re-fires on every subsequent navigation including this reload, silently overwriting the evaluate()'d 'en' value before the recovery flow's English- regex navigation ran - producing exactly the observed "element(s) not found" failure on clickNavItem(/Settings/i) and its siblings. Fixed by registering a further addInitScript instead of page.evaluate(): Playwright runs registered init scripts in order, so this one now always wins on every subsequent navigation, not just the immediate reload. 2. Recovery navigation was not actually locale-independent, despite ensureWelcomePortalEntry()'s own documented contract. Added stable data-testid attributes (settings-nav-data, factory-reset-button, factory-reset-confirm-button) to the three recovery-flow buttons and switched the helper to use them instead of translated-text regex matching, making the contract true independent of fix 1. 3. Factory Reset's own deleteDatabase() treated an IndexedDB "blocked" event as success (the comment admitted this: "resolve anyway; page reload will finish the job") - but a blocked delete does not get retried by an unrelated reload, so the database can survive completely intact while the reset reports success. This page's own known IDB connections (dbService's main chain, the encryption migration journal store, the passphrase sentinel store) are now explicitly closed before any deleteDatabase call, removing the most likely blocker; a genuine external block (another open tab) is now logged rather than silently swallowed. This is a real product defect, not only a test artifact - a user hitting the same race could see Factory Reset silently fail to actually clear data. Also refactors waitForSpaReady's repeated isVisible().catch(()=>false) boolean-soup pattern into an explicit resolveStartupState() -> 'WELCOME_PORTAL' | 'MAIN_CHROME' result, used throughout ensureWelcomePortalEntry. Scope note: this fixes the two confirmed mechanisms above with full source-level evidence and passing unit/type/lint checks. It does not claim to have reconstructed every historical #532 signature across the full Mobile-Chrome/Chromium repeat-each stress matrix locally (this machine's established policy reserves heavy Playwright/E2E runs for CI, not local execution) - CI's own targeted run against this branch is the stress evidence for this PR. The service-worker controllerchange/autosave-race investigation was not pursued further once two independent, fully-evidenced root causes already explained the observed failures; if a distinct SW/autosave mechanism resurfaces after this fix lands, it should be tracked as its own #532 follow-up rather than assumed pre-emptively.
…OU close race, locale-independent settings nav Amazon Q and CodeRabbit both flagged that deleteDatabase()'s onblocked handler still resolved as success, so factory reset could report a "fresh install" while the database was still intact — it now rejects, and both callers surface the failure instead of reloading past it. CodeRabbit also found a TOCTOU gap: closing IDB connections before the await clearTauriAppData() window let a concurrent read/write reopen one before deleteDatabase ran. Connections now close immediately before the delete call, with no intervening await. Graphite found the connection-close-order test only verified one of three closes; it now verifies all three, plus a new deterministic test for the reject-on-blocked path. CodeRabbit additionally verified against Playwright's own docs that addInitScript execution order across multiple registrations on one page is unspecified — contradicting this PR's own in-order-execution premise for forcing English before the recovery flow. The recovery flow's one remaining locale-dependent step (clicking Settings by translated label) now uses the existing stable data-tour="nav-settings" anchor instead, making the whole flow genuinely locale-independent without needing to force a language at all.
…set, not just three
CodeRabbit found that moving the three known connection closes right
before deleteAllIndexedDBDatabases() removed the clearTauriAppData()
await window but not the underlying race: IdbConnectionManager.initDB()
can already be in flight when the close runs, and its onsuccess handler
can repopulate stateDb/dataDb afterward; deleteAllIndexedDBDatabases()'s
own await indexedDB.databases() opens another such window.
cubic separately found the fix's real-world scope was too narrow even
without any race: services/diagnostics/logSinks.ts, sceneRevisionService,
aiInferenceCacheService, loraAdapterService, both ProForge stores,
crossProjectIndexService, and the worker-bus dead-letter queue each cache
(or, for loraAdapterService/deadLetterQueue, silently leak) their own IDB
connection independently of IdbConnectionManager — none of them were ever
closed, so a completely normal session (logging alone opens
worldscript-logs-db) would make the reset's new reject-on-blocked
behavior fail every time instead of only when something was actually wrong.
Replaces the three hand-wired close-for-reset exports with
services/storage/idbResetGate.ts: a shared registry every long-lived-
connection module registers into once, plus an isIdbResetInProgress()
flag every one of those modules' own onsuccess handlers now checks before
caching a newly opened connection. wipeAllAppData() calls beginIdbReset()
once, first, covering the whole reset rather than one point in time, and
endIdbReset() only on a failure path that never reaches reload.
Also, while in this area:
- loraAdapterService and the dead-letter queue never cached a connection
at all (a new one leaked per call) — converted both to the same
single-flight cached pattern already used elsewhere in this codebase,
which is what let a factory-reset closer be registered for them.
- KNOWN_DB_NAMES (the Safari/old-browser deleteDatabase fallback) was
missing proforge-run-history and worldscript-dead-letter-db.
- cubic also found the reused encryptionRecoveryFailed toast falsely told
users "your data has not been lost" after a factory-reset failure that
can follow partial cleanup — added a dedicated, honest
factoryReset.failed message instead (all 19 locales; de/es/fr/it
hand-translated, others via the standard i18n:fix propagation, which
also reconciled unrelated pre-existing drift in those same files).
- cubic found the E2E recovery flow's factory-reset-button testid only
existed on the encryption-recovery modal's button, never on the actual
Settings > Data & Backups button ensureWelcomePortalEntry navigates to
— added it there too.
- cubic and the user's own review both found clickSettingsNavItem's
mobile "More" button still matched translated text
(getByRole('button', {name: /More/i})) despite the helper's stated
locale-independent contract — added a stable data-tour="nav-more"
anchor and a new E2E regression combining a persisted non-English
language with the actual recovery-flow path (the existing Spanish test
only ever hit a fresh WelcomePortal boot, never this path) so it's
exercised on Mobile Chrome, not just asserted possible.
Investigated Sourcery's separate concern about an unaddressed
service-worker "double boot": confirmed sw.js's clients.claim() plus
register-sw.ts's unconditional reload-on-controllerchange does fire on a
brand-new browser context's very first load, not only on a version
update. Tracked as #585 rather than folded in here — it's a production
SW-behavior question needing its own review, not a test-harness fix.
…SettingsView CodeScene flagged useSettingsView (an already-tracked Complex Method hotspot) declining slightly (7.89 -> 7.86) from the try/catch this PR added to handleFactoryReset. Extracting the catch body into a standalone reportFactoryResetFailure() function moves that branch out of the hook's own body entirely rather than suppressing the finding; behavior is unchanged (same 41 tests pass).
…ingsView The prior extraction only moved the catch body out; the try/catch structure itself (a branch) stayed in useSettingsView's own body, so CodeScene's hotspot-decline gate still failed (7.89 -> 7.87). The whole try/catch now lives in performFactoryReset(); handleFactoryReset stays async/awaitable (existing call sites and tests already await or void-wrap it) but its own body is a single straight-line await, no branch at all.
…y long-lived IDB connection Root-cause review (CodeRabbit, cubic, and direct maintainer review) found the prior synchronous registry/boolean-flag design insufficient for the actual failure classes it needed to cover: - beginIdbReset() is now async and awaits every registered closer's teardown (Promise.allSettled, fail-closed — a rejecting closer is logged but never silently drops the reset back to "not in progress"). wipeAllAppData() awaits it before any deleteDatabase() call, closing the y-indexeddb docPersistence.ts case where destroy() is genuinely async and the prior fire-and-forget registration silently discarded its promise entirely (a block-bodied arrow that never returned it). - A monotonic generation/epoch counter replaces boolean-flag checks in every module's open-completion handler. isIdbResetInProgress() alone cannot distinguish "no reset ever happened" from "a reset happened, failed, and ended" once the flag flips back to false — exactly the race a failed reset followed by a stale late-completing open would hit. Every touched module now captures the generation before starting an open and compares it again at completion, discarding the result if a reset occurred in between regardless of how that reset resolved. - Late registration during an active reset is no longer a way to escape it: registerIdbConnectionCloser() invokes the closer immediately against the current reset instead of enrolling it for a future one. - Reset-failure retryability audited and fixed per store: AiInferenceCacheService's dbReady was a one-shot constructor-time promise that permanently fell back to in-memory-only for the rest of the session if the very first open lost a race with a reset — replaced with a retryable ensureDb(). proForgeMemoryBank, proForgeHistoryStore, and crossProjectIndexService all had latent rejected-promise-cached-forever bugs (proForgeMemoryBank's was unconditional, not just reset-triggered) — none now leave a permanently dead single-flight promise. logSinks additionally clears its cached record count on close, since it describes a now-closed connection's contents. - onversionchange (another tab's own deleteDatabase, or its own factory reset) was entirely missing from proForgeMemoryBank, crossProjectIndexService, and the worker-bus dead-letter queue — added, closing and invalidating the cached handle exactly like the modules that already had it. - deleteDatabase()'s onerror silently treated any error as "DB may not exist" and resolved; deleting a genuinely absent database succeeds per spec, so a real onerror means deletion is unproven — now rejects. This uncovered a real bug in deleteAllIndexedDBDatabases(): its own try/catch wrapped both enumeration AND the per-database deletes, so a real deletion failure was silently swallowed and retried through the Safari-fallback known-name-list path instead of propagating — separated so only enumeration failure falls back. - app/listenerMiddleware.ts's getLocalFirstHandle() returned an already factory-reset-destroyed handle as if still live whenever the same project was requested again, because its only staleness check was for the unrelated "encryption became active" case — writes would have silently gone nowhere for the rest of the session. Now also recreates when persistence.active is false and it isn't the intentional NOOP fallback (reference-checked against the real NOOP_PERSISTENCE singleton, imported earlier so the check can use it). - Fixed two ordering/TDZ bugs the above surfaced along the way: a docPersistence.ts closer referencing destroy()/unregister() before either was initialized (real risk once late-registration-during-reset can invoke a closer synchronously), and factory-reset-button's data-testid colliding between DataSection.tsx (the actual Settings page ensureWelcomePortalEntry navigates to) and FactoryResetDangerZone.tsx (used only inside the encryption-recovery modals) — the latter renamed to encryption-recovery-factory-reset-button. - tests/unit/settings/EncryptionRecoveryModal.test.tsx and IdbUnlockModal.test.tsx asserted the old encryptionRecoveryFailed message on the factory-reset path specifically (their other, genuinely-different-flow assertions of that same message were left alone) — updated to the dedicated factoryReset.failed key. The E2E Spanish-locale regression now asserts the persisted language value directly rather than only proceeding on the assumption addInitScript applied it, so a broken seed can no longer pass the test vacuously. - Reverted the unrelated common.json/sidebar.json changes across 18 locales that a prior check-i18n-keys.mjs --fix invocation pulled into this diff — verified those files already matched main exactly before reverting, so this is pure scope discipline, not a translation regression; the one actual new key (factoryReset.failed) and its bundle rebuild are unaffected. Regression coverage added: idbResetGate.test.ts rewritten for the async generation-based contract (awaited async closers, late registration against the live reset, fail-closed closer-failure handling, generation mismatch surviving past a failed reset's end); a new dedicated aiInferenceCacheServiceResetRetry.test.ts proves durable IDB round-trip survives a failed reset through a second service instance (ruling out the in-memory LRU masking the read).
…e-flight races Redesigns idbResetGate.beginIdbReset() to fail closed: any closer failure now rejects the reset (after every closer, including failing ones, has run) so wipeAllAppData() aborts before any database deletion instead of proceeding on an unproven teardown. A closer registered while the reset is draining now joins that reset's own awaited barrier instead of racing ahead of it, so beginIdbReset() cannot settle while a late connection is still closing. Fixes stale-open-completion races (an in-flight open's callback could null out a newer promise reference) via an identity token in proForgeHistoryStore, loraAdapterService, and packages/worker-bus's DeadLetterQueue; the latter also guards against indexedDB.open() throwing synchronously, which previously left openPromise permanently memoized as a rejected promise. loraAdapterService's _resetLoraDbForTest() now closes/clears its cached handle before swapping the fake IndexedDB factory. persistProjectDoc() degrades to the NOOP handle while a reset is in progress instead of opening a provider only to tear it down. Further extracts getLocalFirstHandle's classification/reuse/teardown logic into reconcileLocalFirstHandle to address a CodeScene cyclomatic-complexity regression, mirroring the same fix already applied to useSettingsView. Completes real (non-English-fallback) translations for settings.data.dangerZone.factoryReset.failed across the 14 locales that still carried English placeholder text for this destructive-reset-failure message, and reverts 17 sidebar.json files that had picked up trailing-newline-only churn unrelated to this change.
…reset The existing generation check invalidates an open that started BEFORE a reset and completes after the generation advances, but not one that STARTS after beginIdbReset() already bumped the generation: it captures that same already-current generation, so the comparison at completion still matches and the connection gets cached during an active reset. Adds a centralized beginIdbOpenAdmission()/isIdbOpenStillValid() pair to idbResetGate — refuse admission (no indexedDB.open() call at all) while a reset is in progress, and re-check both !isIdbResetInProgress() and the generation match at completion — then rolls it out to every reset-aware opener: idbCore, loraAdapterService, sceneRevisionService, logSinks, aiInferenceCacheService, crossProjectIndexService, both ProForge stores, and the worker-bus DLQ. Also adds the missing current-flight identity token to sceneRevisionService, logSinks, crossProjectIndexService, and proForgeMemoryBank, matching the pattern already applied to the other stores. factoryResetService.deleteAllIndexedDBDatabases() now uses Promise.allSettled instead of Promise.all so a fast-rejecting deletion can no longer let wipeAllAppData()'s catch release the reset gate while another deletion is still outstanding in the background — every deletion must settle before the aggregate result is known. Strengthens the AI cache reset-retry test to actually start an open, begin the reset while it's still in flight, and prove the stale open is discarded and a subsequent write durably retries — the prior test only exercised a sequential open/reset/open, never the in-flight race. Fixes a sibling test still awaiting the removed dbReady field instead of the retryable ensureDb().
…e, transient reset NOOP Adds a real app-ownership predicate to factoryResetService's database deletion target list — a shared origin can host an unrelated app's IndexedDB database, and indexedDB.databases() enumerates the whole origin, so a successful native enumeration is now filtered through isWorldScriptOwnedDatabaseName() (exact KNOWN_DB_NAMES plus the worldscript-localfirst-<projectId> prefix) before any deleteDatabase() call is ever constructed. Adversarial test proves a foreign database is never targeted even when mixed into a real enumeration result. Fixes the actual root cause of the single-flight synchronous-open-throw bug across 7 openers (DeadLetterQueue, loraAdapterService, sceneRevisionService, logSinks, crossProjectIndexService, proForgeMemoryBank, proForgeHistoryStore): the previous per-handler "clear the cache slot in the catch block" fix was silently undone by the unconditional `openPromise = thisOpen` assignment that runs immediately after Promise construction, regardless of whether the executor already rejected synchronously. Replaces it with a single ownership-checked `.finally()` cleanup per opener that runs after that assignment, on every settlement path uniformly. loraAdapterService's openDb() also gates publishing on flight identity (`openPromise !== thisOpen`) so a stale open — one whose completion arrives after _resetLoraDbForTest() has already cleared state and swapped the fake IndexedDB factory — closes and discards itself instead of caching a connection bound to the discarded factory. Regression test forces exactly this ordering. persistProjectDoc() now returns a fresh, distinct-identity NOOP object when denying an open because a reset is in progress, rather than the shared NOOP_PERSISTENCE singleton — reconcileLocalFirstHandle's existing "dead reference, not an intentional NOOP" branch already discards anything that isn't identical to the singleton, so a handle cached during an active reset is no longer reused indefinitely once the reset ends and real persistence becomes available again.
…ertion README's test-metrics section still said "2026-08-30" despite the counts having been resynced repeatedly since — updates the label to match. Strengthens the pre-reset-connection test: a durable post-reset round-trip alone doesn't prove the pre-reset connection actually closed, since a still- open connection would pass the same assertion. Captures the internal db reference before the reset and proves it's nulled by the closer, then that a genuinely new connection object exists after the retry.
…t the cached database Audited all 7 reset-aware single-flight openers: proForgeHistoryStore, proForgeMemoryBank, and crossProjectIndexService already cleared their pending-flight variable in the registered closer, but loraAdapterService, sceneRevisionService, deadLetterQueue, and logSinks only closed the (still null, not-yet-open) cached database, leaving the in-flight promise published. After a reset, the first legitimate post-reset caller reused that stale, already-invalidated flight instead of starting a fresh one — it had to wait for the stale flight's own eventual generation-mismatch rejection before any subsequent caller could retry. Clears the pending-flight variable in all 4 closers, matching the pattern already used by the other 3 stores. Adversarial test in loraAdapterService.test.ts proves an immediate post-reset operation gets a genuinely new flight while the late-completing stale open discards itself harmlessly. Also fixes tests/unit/listenerMiddleware.test.ts's mocked NOOP_PERSISTENCE and persistProjectDoc() return value, which omitted destroy()/clearData() — real listener teardown code can call both on any persistence handle. Uses stable mock function references so tests can assert teardown was invoked.
…eview - listenerMiddleware.ts: encryption-disable is now symmetric with the encryption-enable branch already handled -- a handle that chose the shared NOOP_PERSISTENCE singleton because encryption was ready is discarded once encryption is later disabled, so local-first sync resumes durable persistence instead of staying memory-only forever. - aiInferenceCacheService.ts: the reset closer now clears openPromise too (identity-checked, matching crossProjectIndexService.ts's established pattern), not just db -- a caller made before the stale in-flight open settles now starts a fresh attempt instead of reusing the invalidated one. - idbResetGate.ts: a concurrent beginIdbReset() call now joins the already-draining barrier instead of overwriting activeBarrier -- a closer that registers during the overlap window no longer risks being orphaned into a barrier only the second caller awaits, which could let the first caller proceed into deletion before that closer's teardown actually finished. Also retained from the prior commit: the earlier fix added destroy()/clearData() to the mocked NOOP_PERSISTENCE and persistProjectDoc() return value (a real type-fidelity gap), but claimed in its own comment that this let tests assert teardown was actually invoked while no test did. Adds that assertion for the one mock actually exercised (mockNoopDestroy, via the OFF-transition warmup teardown), and simplifies the other three back to plain no-op closures rather than stable mock references nothing asserts on.
…escence gate Independently reviewed by CodeAnt, CodeRabbit, and cubic; the following were confirmed valid against the current code and fixed: - docPersistence.ts: the reset closer unregistered before its underlying provider.destroy() settled (couldn't be awaited by the barrier), and a rejected destroy() was silently swallowed before the reset gate ever saw it. Split into a raw beginDestroy() the closer awaits directly and a no-throw destroy() wrapper for the many defensive callers. - idbResetGate.ts: a closer that registers after the drain loop already emptied (but before endIdbReset()) was never invoked at all -- now it still runs, just unawaited. A closer that itself registers another closer mid-drain could be invoked twice via the live Set iteration -- now snapshotted. - idbCore.ts: concurrent initDB() callers before the first open resolved each started their own indexedDB.open(), letting the last onsuccess silently orphan every earlier connection untracked by closeConnections(). Added the same single-flight + identity-checked-cleanup pattern already used by the sibling services this PR touches, plus a live-handle guard (a follow-up coderabbit pass on this same fix found initDB() would still reopen an already-live sibling database whenever only the OTHER one needed a fresh open). - factoryResetService.ts: deleteDatabase() rejected immediately on onblocked, but the same request can still reach a real onsuccess once the blocking connection closes -- settling early let wipeAllAppData() release the reset gate while deletion was still asynchronously pending. Now waits for the real terminal event, bounded by a timeout. - sceneRevisionService.ts: missing the identity check loraAdapterService already has, so a stale open completing after _resetDbForTest() swapped the fake IndexedDB factory could still get cached. - loraAdapterService.test.ts: beforeEach swapped the fake factory without first releasing the previous test's cached connection. - FactoryResetDangerZone.tsx: removed a data-testid nothing consumes. - locales/he/settings.json: informal imperative forms in the new factory-reset message, inconsistent with the surrounding formal copy. - Test wording/mock-leak fixes: aiInferenceCacheServiceResetRetry.test.ts's first test claimed a "failure" it doesn't exercise (a clean abort, not a closer rejection); listenerMiddleware.test.ts's isIdbEncryptionReady override wasn't reset between tests, unlike the file's own established mockIsFactoryResetInProgress pattern; onboarding-entry-precondition.spec.ts had a comment describing the inverse of what the test actually does. Regression tests added for the idbCore.ts single-flight and live-handle fixes and the onblocked/onsuccess ordering fix.
…scence gate codecov/patch failed at 67.20% (target 74.99%) on this PR's own diff. Investigated by downloading and directly inspecting the actual CI-generated lcov.info artifact (not just the Codecov dashboard, which can lag): the gap is real, not stale data -- Codecov correctly counts a line with only partial branch coverage as not-fully-covered, and this PR's own review-fix commits had left the reset-in-progress-rejection, generation-mismatch, onversionchange, and onerror branches largely untested across most of the 9 service modules the reset gate covers. Adds targeted reset-gate interaction tests (reset-in-progress rejection, and the actual generation race: a second reset beginning while an open started right after the first reset closed the prior connection is still in flight, before its onsuccess has fired) to: - services/storage/idbCore.ts (both the single-flight and the live-handle-guard fixes, plus the symmetric dataDb-live/stateDb-null case the earlier test didn't cover) - services/crossProjectIndexService.ts - services/diagnostics/logSinks.ts - services/proForge/proForgeHistoryStore.ts - services/proForge/proForgeMemoryBank.ts - packages/worker-bus/src/deadLetterQueue.ts No production code changed -- test-only, closing genuine coverage gaps against code this PR's own earlier commits already added.

Summary
Succeeds #583, which GitHub permanently blocks from reopening after its branch was force-pushed with a rebase ("state cannot be changed... branch was force-pushed or recreated" — a documented, irreversible GitHub restriction once a PR is closed). All of #583's review history, discussion, and findings remain readable there; this PR is the same work, rebased onto current main.
Full async, generation/epoch-based IDB reset-quiescence contract covering every long-lived connection in the app (9 service modules plus the shared gate itself). The gate fails closed —
beginIdbReset()rejects if any registered closer fails, after every closer has still had its chance to run, sowipeAllAppData()aborts before any database deletion on an unproven teardown — and a closer registered while a reset is draining joins that same awaited barrier instead of racing ahead of it as fire-and-forget. A centralizedbeginIdbOpenAdmission()/isIdbOpenStillValid()pair closes a further gap: an open that starts after a reset already bumped the generation would otherwise still match at completion, so every opener also refuses to start a fresh open while a reset is in progress — and every reset closer now also invalidates its own module's pending open flight, so the first post-reset caller starts a genuinely fresh attempt instead of reusing one already doomed to reject.deleteAllIndexedDBDatabases()usesPromise.allSettledso a fast-rejecting deletion can't release the gate while another is still outstanding, and only targets database names it can prove it owns (exactKNOWN_DB_NAMESplus theworldscript-localfirst-prefix).Reconciliation with main since #583 was originally opened

Summary by cubic
Factory reset previously raced long-lived IndexedDB connections and could report success when deletion was blocked, leaving data intact; it now drains and validates every connection before deleting, aborts before any deletion when teardown fails, and deletes only databases the app owns. WelcomePortal recovery navigation no longer depends on translated labels, removing startup and locale-related E2E nondeterminism.
