The changes correctly fix the VRT navigation contract issue. The trailing slash addition to baseURL combined with relative navigation ('./' instead of '/') ensures tests reach the actual app under /WorldScript-Studio/ rather than the server root. The new assertRealAppLoaded guard provides strong validation that the app loaded correctly before screenshots. The migration from non-functional hash fragments to the established clickNavItem/ensureBlankProject pattern aligns with existing e2e specs. The implementation is sound with no blocking defects identified.

Codecov Report✅ All modified and coverable lines are covered by tests. 📢 Thoughts on this report? Let us know! |
Root cause (proven empirically via node's URL resolver, not assumed):
every VRT test navigated with an absolute path (goto('/...')) while
the shared baseURL's own path is '/WorldScript-Studio' (no trailing
slash). Per the URL spec, an absolute-path reference discards the
base's entire path regardless of trailing slash, so every VRT test
actually loaded the static file server's bare root — which, since the
app's real files live under serve_root/WorldScript-Studio/, rendered
http-server's own directory-listing fallback page instead of the app.
All 4 committed baselines are screenshots of that listing page, not
WorldScript Studio: VRT has provided no real visual-regression
protection since its introduction.
Compounding this, 3 of the 4 tests navigated to '#view=writer' /
'#view=characters' / '#view=settings' — hash fragments no code in
this app has ever parsed — so even with the navigation bug fixed,
those tests would not have reached distinct views.
Fixes, scoped narrowly to VRT rather than the shared config:
- A fully-qualified, VRT-local APP_ENTRY constant replaces every
page.goto('/...') in this one spec file. The shared baseURL in
playwright.config.ts is untouched — every other e2e spec's
page.goto('/') targets Vite's dev server (which serves at root
regardless of the production subpath), so this bug never affected
them and a global config change isn't needed to fix it.
- writer/characters/settings tests now reach their target views via
the same ensureBlankProject + clickNavItem pattern every other e2e
spec in this suite already uses, instead of a URL fragment the
router never read.
- Replaced the assertion `expect(page.locator('body')).toBeVisible()`
— trivially true for a directory-listing page too — with
assertRealAppLoaded(): waitForSpaReady's own landmarks (#sidebar /
welcome-portal) cannot exist on a listing page, plus an explicit
title/text check against "Index of" as a second, independent
signal a listing page can never fake.
Screenshot diff thresholds (maxDiffPixels/maxDiffPixelRatio) are
unchanged. Baseline PNGs are regenerated in a following commit from
real CI evidence, not blindly, plus a negative-control verification
that the repaired gate actually detects a real visual change.

Diagnostic-only commit. Will be reverted before this PR is ready for review — the point is to capture genuine screenshots via the now-fixed navigation, not to leave --update-snapshots wired into CI.

playwright.config.ts sets no outputDir, so Playwright's default (repo-root test-results/) is where actual/diff failure images land — not tests/e2e/test-results/, which the upload step pointed at and which has never existed. This means VRT's own failure artifacts have never actually been captured, hampering exactly the kind of investigation this PR is doing. Genuine fix, not diagnostic scaffolding — kept.

…- forwarding pnpm's own '--' argument-forwarding inserted a second literal '--' before the flag, so Playwright received '--project=chromium -- --update-snapshots' and treated the flag as a positional test-name filter, not the update-mode flag — nothing was ever written. Calling playwright directly via pnpm exec avoids the double-separator. Still diagnostic-only; reverted before this PR is ready for review.

Sorry, something went wrong.
The screenshot-diff comparison alone was too weak: for characters/
settings, the real rendered content on a blank project happens to be
sparse enough that its pixel-diff against the OLD stale
directory-listing baseline fell under maxDiffPixels/maxDiffPixelRatio,
so --update-snapshots silently decided nothing needed updating and
left the broken baselines untouched — even though clickNavItem's
target may or may not have actually been reached. A screenshot diff
can't distinguish "the right view, sparsely rendered" from "the wrong
view that happens to look similarly sparse".
Fixed by asserting each view's own identity before the screenshot:
- writer: getByTestId('writer-studio-editor') (mirrors writer.spec.ts)
- characters: the "Add Manually" button (mirrors characters.spec.ts)
- settings: a "Settings" heading (mirrors voice-flags.spec.ts)
Also deleted all 4 stale baseline PNGs outright so the next
--update-snapshots run treats them as missing and writes unconditionally,
rather than depending on the diff-size heuristic that just caused this
gap.

Regenerated all 4 baselines via CI's real production build, using the repaired navigation/assertions from the prior commits. Each was downloaded and visually inspected before committing — home shows the real WelcomePortal, writer shows the AI Writing Studio editor, characters shows the empty-cast-list state with its own heading, settings shows the full settings panel with its own heading. All 4 hashes are now distinct (previously byte-identical to each other and to a directory-listing page). Reverts the temporary --update-snapshots/--retries=0 direct-playwright invocation back to the normal `pnpm run test:vrt` — that scaffolding existed only to regenerate these baselines from real evidence and has no reason to remain wired into CI.

…e change CI's now-repaired VRT (PR #610) correctly flagged 13,391 pixels of diff (2%, over the 12,000-pixel cap) between the old baseline and this branch's render. Downloaded and visually compared the CI-generated expected/actual pair: layout, text, icons, and positions are pixel-identical — only the color palette differs (warm sepia → cool default), exactly the intentional appearancePreset default change this PR makes. Updated the baseline from the real CI-captured screenshot, not a local re-render. home/characters/settings baselines already passed unchanged — their appearance-driven color exposure apparently falls under the diff threshold, which needed no action.

* docs: trim CLAUDE.md directory map to non-derivable facts only Follow-up from a /doctor pass — most of the per-directory listing was reconstructable via ls; kept only status/versioning facts a session couldn't otherwise discover. * feat(settings): change default appearance preset from sepia to default Product decision: new sessions now start on the standard preset instead of Writer's Sepia. Kept settingsSlice.ts and idbProjectStore.ts's normalization fallback in sync (the exact consistency #332 already required). Audited every test referencing appearancePreset for hidden reliance on the old default rather than explicit setup — found and fixed two: the "dark sepia theme" a11y test relied on sepia being the ambient default rather than selecting it, which would have silently started testing plain dark theme instead of dark-sepia; now explicitly selects Writer's Sepia via the real Settings UI. A normalization test's "preserves explicit override" case used 'default' as its override input, which no longer demonstrates an override once 'default' is the default; now uses 'sepia'. Also fixed unrelated pre-existing drift caught in the same area: Design-System.md still listed the fantasy/romance presets removed in v1.22. Note: VRT baselines (home.png etc.) were captured under the old default and will need regenerating from a real CI diff in a follow-up commit. * test(a11y): add explicit light+sepia dashboard axe coverage The plain 'welcome' test only covers the ambient default now that appearancePreset's default changed away from sepia, silently losing coverage of the exact light+sepia combination in the original #565 evidence. Deterministically sets colorScheme:'light', explicitly selects Writer's Sepia, verifies .light-theme+.appearance-sepia are both applied, then scans the Dashboard with the unchanged serious/critical axe gate — never relies on default or persistence. * fix(a11y): reconcile CodeRabbit findings on #609 — stale doc refs, QNBS-v3 comments, axe wait determinism Removes the two remaining Fantasy/Romance mentions in Design-System.md left over from the single-preset correction, adds the required QNBS-v3 rationale comments to the appearancePreset default-change sites, and replaces both fixed 500ms sleeps before the Dashboard axe scans with an explicit #projectTitle visibility wait so the scan can't run against a not-yet-mounted lazy-loaded view. * test(vrt): update writer.png baseline for the sepia→default appearance change CI's now-repaired VRT (PR #610) correctly flagged 13,391 pixels of diff (2%, over the 12,000-pixel cap) between the old baseline and this branch's render. Downloaded and visually compared the CI-generated expected/actual pair: layout, text, icons, and positions are pixel-identical — only the color palette differs (warm sepia → cool default), exactly the intentional appearancePreset default change this PR makes. Updated the baseline from the real CI-captured screenshot, not a local re-render. home/characters/settings baselines already passed unchanged — their appearance-driven color exposure apparently falls under the diff threshold, which needed no action. * fix(a11y): reorder prefers-reduced-motion override so it actually wins the cascade (#565) The @media (prefers-reduced-motion: reduce) override for .aurora-blob and .animate-in was declared BEFORE their unconditional base rules. With equal selector specificity and no cascade layers in this file, CSS resolves ties by source order — so the later, unconditional base rules always won, regardless of the media query. Reduced motion never actually froze the Aurora background blobs (continuous 25s float animation) or the dashboard cards' staggered fade-in (opacity 0→1, delayed per --index), for any user, including those who explicitly requested it. Evidence: PR #609's new Light+Sepia/Dark+Sepia Dashboard axe tests failed with color-contrast violations whose fgColor/bgColor/contrastRatio swung wildly between retries of the identical, static (zero-value) project state — e.g. the "Worlds" stat label measured 2.38:1 in one run and 1.71:1 in another. That volatility is the signature of axe sampling a still-animating page (backdrop-blur compositing a continuously moving Aurora blob; cards mid-fade), not a stable token-contrast defect — confirmed by tracing both class rules' source order against the override. Moving the override after both base rules lets it win as intended, so prefers-reduced-motion: reduce now actually produces an instantly static render. This is expected to resolve the observed axe flakiness/failures as a side effect; the CI run on this commit is the evidence for whether any residual, non-animation-driven contrast gap remains. * test(a11y): verify Dashboard's fully-settled, normal-motion state is also AA-compliant The reduced-motion cascade fix (previous commit) only proved the reduced-motion path is now deterministic and AA-compliant. Most users don't have prefers-reduced-motion set, so the actual end state they see — after the staggered fade-in animations finish normally — needs its own axe scan rather than being assumed identical.

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 (<!-- release-candidate: v1.28.4 -->) 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.

User description
Status: draft — proving the defect and the fix with real CI evidence before touching baselines
The defect (TEST_CONTRACT / REQUIRED_GATE_INTEGRITY)
All 4 committed VRT baselines (
home-chromium.png,writer-chromium.png,characters-chromium.png,settings-chromium.png) are the same http-server directory-listing page, not screenshots of WorldScript Studio. VRT has provided no real visual-regression protection since it was introduced.Root cause, proven empirically (
node -eagainst the real URL resolver, not assumed):playwright.config.ts'sbaseURLwas'http://127.0.0.1:3000/WorldScript-Studio'(no trailing slash), and every VRT test navigated withpage.goto('/...')— an absolute path. Per the URL spec, an absolute-path reference discards the base's entire path regardless of any trailing slash:Only the second form (trailing slash on
baseURLand relative navigation) lands on the app. The static file server serves the app's real files fromserve_root/WorldScript-Studio/, so hitting the bare root instead returns http-server's own directory-listing fallback — which is exactly what's baselined.This didn't surface anywhere else because the required
e2ejob usespnpm run dev(Vite's dev server), which serves at root regardless of the production GH-Pages subpath — the same buggybaseURL"accidentally" resolves correctly there. VRT is the only suite mirroring the real production subpath structure, so it's the only place this actually breaks.Compounding defect: 3 of the 4 tests navigated to
#view=writer/#view=characters/#view=settings— hash fragments no code in this app has ever parsed (confirmed via full-codebase search). Even with navigation fixed, these wouldn't have reached distinct views.Weak assertion:
expect(page.locator('body')).toBeVisible()is trivially true for a directory-listing page too — it has a visible<body>. This is why the bug was never caught.The fix
baseURLnow ends in/; everygoto()uses relative navigation (./...).writer/characters/settingstests now reach their targets via the sameensureBlankProject+clickNavItempattern every other e2e spec in this suite already uses, not a fragment the router never read.assertRealAppLoaded(): calls the suite's ownwaitForSpaReady(whose landmarks —#sidebar,welcome-portal— cannot exist on a listing page) plus an explicit check that the page title/body text isn't "Index of" — an independent second signal a listing page can't fake.maxDiffPixels: 12_000,maxDiffPixelRatio: 0.06) are unchanged.Remaining steps (this draft)
--update-snapshots), inspect the resulting PNGs directly to confirm they show the actual app.Explicit non-goals
Not touching #609 (Welcome/Home WCAG contrast + appearance-preset default change) — that PR is preserved as-is and will be rebased onto this fix once merged, so the repaired VRT gate is what determines whether #609's visual change legitimately needs new baselines.
