Summary

Closes the P0 cross-project AI mutation finding from the #704 remediation plan (Wave 0B). Five handlers across four hooks await dispatch(aiThunk) and then unconditionally mutate persisted project state, with no check that the active project is still the one the request was made for. Since loading a different project (New Project reset, file import, snapshot restore) replaces state.data wholesale while the SPA stays mounted, a late-arriving AI result could be applied to whichever project happened to be open when it resolved:

  • useCharacterView/useWorldView's handleGenerateProfile/handleRegenerateField
  • useTemplateView's handleAiApply/handleGenerateCustom (most severe — replaces the entire manuscript/outline wholesale, including on the failure-fallback path)
  • useOutlineGenerator's apply() (fired later on a separate click, racing against generate()'s local-state population)

This repo already has the exact right invariant for the analogous snapshot-restore race (restoreSnapshotThunk's storage-owned target-identity capture/recheck). Extracted that into a shared features/project/projectIdentity.ts (getProjectTargetIdentity() + a new captureActiveProjectIdentity() reading the live store via appStoreRef), and applied the same capture-before/recheck-after pattern to all five handlers.

Test plan

  • 9 new regression tests (one per guarded handler/path), each mutation-tested (reverted the guard, confirmed the exact test failed, restored it)
  • All existing tests for the 4 affected hooks + projectManagementThunks pass unmodified
  • pnpm run lint clean
  • pnpm run typecheck (tsgo, 4 checkers) clean
  • pnpm run ci:prepush clean

Summary by Sourcery

Guard asynchronous AI results and deferred outline application so they are only persisted to the project that initiated them.

Bug Fixes:

  • Prevent stale AI-generation results from mutating a different active project after project switches, resets, imports, or snapshot restores.
  • Protect template manuscript replacements and outline application, including failure fallbacks, from cross-project updates.

Enhancements:

  • Centralize project identity checks and distinguish same-ID project sessions with an in-memory generation counter.
  • Extend identity protection to outlines seeded before generation and strengthen snapshot-restore ownership checks.

Tests:

  • Add regression coverage for all guarded AI-generation paths, same-ID project races, outline previews and application, and shared identity behavior.

Summary by cubic

Fixes a race condition where AI generation results (character/world profiles, regenerated fields, template personalization, outline generation) could be applied to a different project than the one that requested them, if the user switched projects while the request was in flight. The five affected handlers now capture the active project's identity before dispatching and discard the result if it changed by the time the request settles — including stale outline previews before Apply.

Bug Fixes

  • Extracts the project-identity guard from snapshot restore into shared features/project/projectIdentity.ts and applies it to all five handlers.
  • Adds an in-memory generation counter to ProjectSliceState, bumped on reset/import/restore, so two fresh projects that both reuse the sentinel id: 'default' are still distinguishable.
  • Guards fail closed: an identity that can't be determined is never treated as unchanged.
  • Captures outline identity eagerly at mount so a seeded outline is protected, and discards a stale preview (local state, toasts) if the project changes during generate().
  • Adds regression tests covering each guarded path, including the same-id reset-versus-pending-restore race.

Written for commit c8a128c. Summary will update on new commits.

CodeAnt-AI Description

Prevent late AI results from changing the wrong project

What Changed

  • AI-generated characters, worlds, outline previews, and templates are discarded if the user switches, resets, imports, or restores a project while generation is in progress
  • Outline Apply now stops instead of replacing another project's manuscript when the outline belongs to a previous project
  • Snapshot restores also stop when the active project changes, including resets that reuse the default project ID
  • Added regression coverage for switched-project and same-ID reset scenarios

Impact

✅ Prevents cross-project AI content changes
✅ Protects manuscript and outline replacements
✅ Prevents stale snapshot restores

…tive project (Wave 0B)

Closes the P0 cross-project AI mutation finding from the #704 remediation plan: five handlers
across four hooks await dispatch(aiThunk) and then unconditionally mutate persisted project
state, with no check that the active project is still the one the request was made for.

Since loading a different project (New Project reset, file import, snapshot restore) replaces
state.data wholesale while the SPA stays mounted -- none of these require a page reload -- a
late-arriving AI result could be applied to whichever project happened to be open when it
resolved, not the one that requested it:

- useCharacterView.handleGenerateProfile/handleRegenerateField and useWorldView's equivalents
  add a whole new character/world or overwrite a regenerated field into whichever project is
  current when the request settles.
- useTemplateView.handleAiApply/handleGenerateCustom call applyToManuscript, which replaces the
  entire manuscript and outline arrays wholesale -- the most severe of the five, since it can
  silently overwrite a different project's content outright, including via the failure-fallback
  path (personalizeTemplateThunk rejecting still applies the original remixed sections).
- useOutlineGenerator's generate() only touches local React state, but apply() (fired later,
  on a separate user click with no await of its own) dispatches the wholesale manuscript/outline
  replacement built from that stale local state.

This repo already has the exact right invariant, established and reviewed for the analogous
snapshot-restore race: projectManagementThunks.ts's restoreSnapshotThunk captures a
storage-owned target identity before the async operation and re-checks it after, rejecting a
restore whose target changed underneath it. Extracted that identity function (byte-for-byte,
including its own pre-existing local LEGACY_PROJECT_DIRECTORY_METADATA_KEY duplicate -- left
as-is, unrelated to this fix) into features/project/projectIdentity.ts as
getProjectTargetIdentity(), plus a new captureActiveProjectIdentity() that reads appStoreRef's
live store directly so a React hook can capture identity at dispatch time and re-check it after
an await, independent of its own render cycle -- restoreSnapshotThunk now imports the same
shared function instead of a private duplicate.

Each of the five handlers now captures the active project's identity immediately before
dispatching its AI thunk and discards the result (no mutation, no toast) if that identity no
longer matches once the request settles. useOutlineGenerator's apply() instead compares against
the identity captured by the most recent successful generate() (stored in a ref), since apply()
itself never awaits anything -- the race is between generate() populating local state and a
later, separate Apply click.

Nine new regression tests (one per guarded handler, one for the outline generator's ref-based
variant), each mutation-tested by temporarily reverting the guard and confirming the exact new
test failed before restoring it. All existing tests for the four hooks and
projectManagementThunks pass unmodified -- none of them wire up appStoreRef, so
captureActiveProjectIdentity() returns null on both sides of every existing call, which the
guard already treats as "unchanged".

Reviewer's Guide

The PR closes the cross-project AI mutation gap by capturing a storage-owned active-project identity before asynchronous generation, rechecking it before persisted mutations (or delayed outline Apply), and discarding stale results—including template failure fallbacks—while adding regression tests for all five affected handlers.

…tity guard, flatten CodeScene nesting

Review on PR #707 (CodeAnt-ai, confirmed and independently re-derived) found a real gap in the
project-identity guard just added: resetProject (the "New Project" action) always resets to the
sentinel id:'default', so two genuinely different fresh-project sessions -- or a reset racing a
pending snapshot restore -- would both compute the same identity and incorrectly pass the guard.
This affected the newly-added hook guards AND restoreSnapshotThunk's own pre-existing,
previously-merged guard (the one this PR's guard was modeled on) -- restoreSnapshotThunk was
critically exploitable, not just the new hooks.

Added an in-memory-only generation counter to ProjectSliceState (never persisted -- save paths
read only .data), bumped by resetProject/importProjectThunk.fulfilled/restoreSnapshotThunk.fulfilled,
and folded into every identity comparison via getProjectTargetIdentity(). Made the field optional
and every increment nullish-coalesced so pre-existing hand-built test store fixtures across the
suite (which predate this field and never read it) don't need touching.

Also fixed useOutlineGenerator's guard, which only started tracking identity after a successful
generate() call -- an outline seeded from the existing project's data and never regenerated
stayed permanently unguarded (CodeAnt, confirmed). generatedForProjectIdentity now captures
identity eagerly at mount instead of starting null.

Separately, CodeScene flagged "Bumpy Road Ahead" (nested conditional logic) on the three hooks
whose guard wrapped the existing fulfilled/else branch in an outer if. Flattened all of them to
early-return guard clauses -- same behavior, no nesting.

Three new regression tests: getProjectTargetIdentity's generation-awareness (unit), the
resetProject-vs-pending-restore race directly (mutation-tested: reverted the generation bump,
confirmed the exact new test failed, restored it), and useOutlineGenerator's eager-capture fix
(also mutation-tested the same way). All 274 tests across every file this change touches or could
plausibly affect pass unmodified.

…le outline previews

Further review (coderabbitai, cubic-dev-ai) on PR #707 found two more real gaps:

- Every identity guard compared capturedIdentity !== liveIdentity directly, so if identity could
  not be determined at all (both sides null -- e.g. a project with neither an id nor a legacy
  directory), the guard treated that as "unchanged" and allowed the mutation. Extracted a shared
  identityUnchanged(captured, live) that fails closed (null never equals itself), and switched
  every guard -- all four hooks plus restoreSnapshotThunk's own pre-existing guard -- to use it
  instead of hand-rolled comparisons, so this can't drift out of sync again.

- useOutlineGenerator's generate() updated the local outline preview and showed a success/error
  toast unconditionally, even when the active project changed while the request was in flight.
  apply()'s guard only protects the later persisted write; a user could still see and be misled
  by a stale preview for a project they've since left. generate() now discards its own result
  (no local-state update, no toast) using the same identityUnchanged() check.

Six new regression tests: identityUnchanged's fail-closed behavior (unit, mutation-tested),
generate()'s success/failure discard (both mutation-tested), a same-project generate-then-apply
happy path for useOutlineGenerator (the guard's non-discard branch was previously unexercised by
any test), and the useTemplateView failure-fallback discard path specifically (the previous test
only covered the fulfilled branch, not applyToManuscript(remixedSections) on rejection -- the
more severe of the two per this PR's own commit history). Added a QNBS-v3 rationale to the two
character-view identity tests per repo convention. All 179 tests across every affected file pass.

Guard section regeneration with the outline owner identity.

handleRegenerate updates local outline after its await without checking generatedForProjectIdentity.current. If project A's seeded outline remains mounted after switching to project B, this handler can replace a section in A's outline while B is active. The apply guard prevents persistence, but the stale preview remains visible.

Check the outline owner identity before dispatch and after completion. Clear isRegenerating on the stale-result path. Add a switched-project regression test.

…point (#726)

* docs: comprehensively refresh README product truth and GitBook entry point

Bootstrap documentation convergence under durable authority issue #724.
Requalifies the curated README candidate against the exact post-#719
main: corrects the AI execution-modes table (Eco is now a strict
no-cloud mode identical to Local, per the #706/#707 privacy-gate fix
merged into main -- assertCloudAiAllowed blocks both equally), confirms
the 23-flag/15-on/8-off feature-flag table matches current source, and
fixes the matching stale 16/7 split in docs/FEATURE-PARITY.md's summary
paragraph (its per-flag table rows were already correct).

Preserves the DeepWiki badge, GitBook EN/DE links, and the
Documentation Hub anchor referenced from a dozen other repository
docs. Restructures around precise, bounded trust-boundary language
instead of the previous "AI-Powered Narrative Universe" marketing
framing -- local-first vs. no-network, encrypted vs. merely local,
and per-platform storage/AI capability differences are now each their
own section rather than folded into sweeping claims.

Refs #724

* docs: remove ghost enableWebnnInference row, fix stale 17/6 drift summary

CodeAnt/CodeRabbit/cubic each independently flagged that the top-level
23/15/8 summary this PR just corrected still contradicted two other
spots in the same file: a ghost enableWebnnInference table row (not a
real FeatureFlagsState field -- zero occurrences anywhere else in the
codebase, confirmed) counted toward an implied 24-flag total, and a
separate Drift Summary section still claimed 17 on / 6 off. Removed
the ghost row and rewrote the summary to match the corrected 23/15/8
split, verified against `pnpm exec tsx scripts/audit-feature-parity.ts`
(0 critical errors, 0 warnings).

…ofread/synopsis (#768)

* fix(project): reject stale deferred AI results in outline/logline/proofread/synopsis

Part of #713 (deferred/apply-later project-incarnation authority). Closes
the "local deferred results" half of the repository-wide sweep required by
that issue -- Writer and Global Copilot (whose retained state lives in
Redux, not component-local state) are a separate, larger follow-up slice.

Audited against current main, verified each gap concretely before fixing
(per this session's established discipline: no speculative fixes):

- outline: generate()/apply() already had #707-identity guards on both the
  local preview and the persisted write; handleRegenerate() (per-section
  regeneration) did not -- a late-arriving regenerated section could
  overwrite the current preview after a project switch. Fixed with the same
  captured-identity-before-dispatch pattern generate() already uses.
- logline (useManuscriptView): handleGenerateLoglines only guarded against
  a newer logline request superseding an older one, never against the
  active project changing; selectLogline() had no guard at all. Added a
  project-identity invalidation effect (clears suggestions and closes the
  modal on identity change, mirroring the existing scene-visualization
  effect) plus an origin-identity ref frozen at successful-generation time
  so selectLogline() independently rejects a stale suggestion even if a
  caller bypasses the (now-cleared) suggestion list.
- proofread (useManuscriptView): handleProofread had no request-race guard
  at all (unlike logline/scene); applyProofreadSuggestion() had no guard.
  Added the same section-and-identity-scoped invalidation, a request-race
  ref matching the existing scene-visualization pattern, and an
  origin-identity ref (frozen at generation time, not continuously
  resynced) for the independent apply-time check.
- synopsis (useExportView): generateSynopsis() had no guard, and the
  generated synopsis was composed into every export format (markdown, PDF,
  DOCX, JSON) with no re-verification -- a stale synopsis from a previous
  project could silently enter a different project's export. Added a
  project-identity invalidation effect that clears synopsis on identity
  change (protecting every export-composition site uniformly, since they
  all read the live synopsis state) plus a mid-flight generation guard.

A real design bug surfaced and was caught by its own regression test during
development: an initial logline fix used a ref that the invalidation effect
kept resynced to the *current* identity, which made the staleness check
always pass (comparing "current" against "current"). Fixed by freezing the
origin identity only at successful-generation time, mirroring outline's
already-correct generatedForProjectIdentity pattern -- and generalized the
same origin-vs-live distinction to proofread's apply-time check.

Nine new regression tests covering: outline per-section regeneration
discarded when stale, logline request discarded mid-flight and selection
rejected after the fact, proofread result discarded mid-flight and apply
rejected both after a project-incarnation change and after a section
change, and synopsis discarded both mid-flight and via export-composition
contamination after the fact. All 95 tests across the three affected hook
test files pass, including every pre-existing same-project happy-path case
unchanged.

* docs(project): reference PR #768 in CHANGELOG.md [Unreleased]

This PR's title is governed (fix(...)), so scripts/check-pr-changelog-reference.mjs
requires a real bullet citing "PR #768" before merge.

* fix(project): close review-wave gaps in logline/proofread/synopsis stale-result guards

- Reset isAiLoading/isProofreading/isGeneratingSynopsis in each invalidation
  effect, not just at async completion, so a superseded request never leaves
  its spinner stuck.
- Track the RESOLVED active section (activeSection?.id), not the raw stored
  activeSectionId, in the proofread target/guard -- another view can delete
  the active section directly, leaving activeSectionId stale while
  activeSection falls back to a different section.
- Re-check identity via a live captureActiveProjectIdentity() call after each
  await (logline, proofread, synopsis), matching useOutlineGenerator's
  established pattern, instead of relying solely on an effect-synced ref that
  isn't guaranteed to have flushed before the request resolves.
- Add a synopsisRequestRef guard so a superseded same-project synopsis
  request can no longer clobber a newer one's content or loading state.

* fix(project): avoid a new suppression-ratchet entry in the synopsis invalidation effect

Replace the trigger-only-dependency + biome-ignore pattern with a
compare-against-previous-value ref so projectIdentity is genuinely read in
the effect body -- CI's suppression-debt ratchet (baseline 48) correctly
rejected the biome-ignore this added in the prior commit.

* fix(project): stop a stale proofread completion from clearing a newer request's loading state

Confirmed independently by cubic, CodeRabbit, and chatgpt-codex-connector on
PR #768's second review wave: the stale-result branch cleared isProofreading
unconditionally, so an older request settling after a newer one started could
cancel the newer request's own loading indicator. Only clear it when the
request counter still matches -- otherwise a newer request (or the
invalidation effect) already owns that state.

* refactor(project): extract handleProofread's staleness check to satisfy CodeScene health gate

CodeScene flagged handleProofread as "Bumpy Road Ahead" (9.10 -> 8.68) after
the recent stale-result guard additions. Extract the three-dimension
staleness check (request supersession, section/project target, live
identity) plus its loading-reset side effect into a small named helper
instead of suppressing the finding.

* fix(project): clear the stale synopsis synchronously before paint on a project switch

CodeRabbit correctly noted formattedOutput's useMemo recomputes with the NEW
project on the same render that projectIdentity changes, while synopsis
state still holds the OLD project's text until the invalidation effect
clears it. Use useLayoutEffect (not useEffect) so that clear is flushed
synchronously before the browser paints, closing the one-frame window where
a mismatched project+synopsis composition could otherwise be visible or
exported.

* fix(project): remove the logline invalidation effect's suppression too

chatgpt-codex-connector correctly noted this PR's logline biome-ignore
(present since the PR's first commit) raises the suppression count from
origin/main's actual 47 to the baseline of 48, consuming the one unit of
slack instead of staying at zero new suppressions. Apply the same
compare-against-previous-value idiom already used for the synopsis effect.
