feat(app): mvp-visual-verify — OCR + palette + pixel-diff + expectation layer over audit:app

[lalalune]

mvp-visual-verify — a higher-fidelity visual-verification layer over audit:app

Evidence tooling (not a new CI gate) that post-processes the screenshots audit:app already captures (packages/app/aesthetic-audit-output/<viewport>/<slug>.png) into a per-state readout a reviewer can trust without re-eyeballing 200 PNGs. For every captured state it produces OCR text, a dominant-color palette, a pixel-diff vs a committed baseline, and a declarative pass/fail over per-state expectations — then writes report.json + an annotated contact-sheet.html.

What it adds

• packages/app/scripts/mvp-visual-verify.mjs — the post-processor. Discovers viewport dirs under the audit output, runs OCR + palette + diff + expectations per <viewport>/<slug>.png, writes a separate mvp-verify/ tree (report.json, contact-sheet.html, diffs/, baseline/) so it never collides with the audit's own report.
• scripts/mvp-visual-verify/ocr.mjs — on-screen text via the system tesseract binary, spawned through child_process. Honest { available:false, reason } degrade when the binary is absent (the OCR column renders "N/A", never fabricated text).
• scripts/mvp-visual-verify/dominant-color.mjs + color-bucket.mjs — sharp decodes to raw RGBA; quantizePalette (pure) buckets to a coarse grid and returns the top-K swatches with brand-bucket labels. The classifier is a faithful ESM port of the audit's own bucket() (test/ui-smoke/aesthetic-audit-rules.ts) and is parity-tested against it across an RGB-cube sweep so the no-blue rule cannot drift between capture and post-process.
• scripts/mvp-visual-verify/diff.mjs — pixel diff with zero new deps: sharp decodes both PNGs, comparePixels (pure) counts changed pixels + per-channel mean-abs delta and paints a magenta-on-dimmed-gray highlight buffer, summarizeDiff (pure) reduces to %. A missing baseline records status:"new" — never a fabricated 0%.
• scripts/mvp-visual-verify/expectation-eval.mjs + expectations.json — declarative per-slug specs (expected OCR substrings present/absent, brand-orange accent, no blue, no horizontal overflow) → pass/fail with reasons. A genuinely-unavailable input (OCR engine absent, report lacks the overflow field) resolves to skip, never a silent pass.
• scripts/mvp-visual-verify/overflow-invariant-demo.mjs — a real headless-chromium demonstration that the horizontal-overflow invariant catches the WS5 transcript bug.
• test/audit/mvp-visual-verify.test.ts — 20 unit tests over the pure functions (parity sweep, quantizer, diff summarizer/comparator, expectation evaluator).
• test/ui-smoke/all-views-aesthetic-audit.spec.ts (modified) — records a document-level horizontal-overflow invariant (documentElement.scrollWidth − innerWidth) into report.json for every view; hard-gated only under ELIZA_AUDIT_APP_STRICT. A measurement failure throws (no fabricated "0 = healthy").
• package.json — mvp:visual-verify, audit:app:verify (= audit:app && mvp:visual-verify), mvp:visual-verify:overflow-demo.

Engines used

Column	Engine	Honest degrade
OCR	system tesseract v5.5.2 (/opt/homebrew/bin/tesseract), spawned tesseract <png> stdout -l eng. tesseract.js is NOT used (not installed).	{available:false} → "N/A (tesseract not found)"
Palette	sharp raw RGBA → hue-based bucketing (ported + parity-pinned to the audit's bucket())	throws on malformed buffer
Diff	sharp raw decode + hand-rolled compare (pixelmatch deliberately not installed)	missing baseline → status:"new"
Overflow	Playwright page.evaluate document-level probe	measurement failure throws

Proof (real screenshots, opened by hand)

Ran against the checkout's real audit:app output — 195 states in ~68s, 3 real findings caught:

[mvp-visual-verify] OCR engine: /opt/homebrew/bin/tesseract
[mvp-visual-verify] viewports: desktop(100), mobile-portrait(95)
[mvp-visual-verify] wrote 195 states → mvp-verify/report.json + contact-sheet.html
[mvp-visual-verify] expectation failures: 3 | overflow states: 0 | new baselines: 195
  FAIL plugin-clawville-tui @ desktop: no-blue: palette blue coverage 91.4% > 5.0%
  FAIL plugin-polymarket-gui @ desktop: ocr-text: forbidden present: undefined
  FAIL plugin-polymarket-tui @ desktop: ocr-text: forbidden present: undefined

Adversarial self-review — each column verified against the actual pixels:

• OCR is real. plugin-polymarket-gui.png OCR read "Cannot read properties of undefined (reading 'ready')"; opening the PNG shows that exact crash string in red on screen. The undefined junk-token expectation fired correctly (whole-word matched, so undefined in finances would not false-fire).
• Palette is real. plugin-clawville-tui palette reported blue 91.4% (dominant swatch #080818 @ 85.3%); the PNG is a dark-navy TUI — a genuine no-blue violation, caught.
• Diff moves with content. Same image vs itself = 0%; builtin-character vs builtin-settings baseline = 93.5% (meanDelta 44.7) with a magenta diff PNG; resized mobile-vs-desktop settings = 36.1% (resized:true). Diff PNG opened: magenta on changed pixels, dimmed-gray on the structurally-shared bands.
• Expectations actually FAIL. 3 of 195 states fail (above) — the evaluator is not a pass-everything rubber stamp. Unit tests additionally assert fail-on-DOM-blue, fail-on-missing-orange, fail-over-overflow-tolerance, and honest skip when OCR is unavailable.
• No larp columns. OCR degrades to explicit N/A without tesseract; diff records new without a baseline; overflow skips when the report predates the field. Nothing is fabricated.

Caught-regression demo (real chromium)

bun run --cwd packages/app mvp:visual-verify:overflow-demo:

[overflow-demo] viewport 390x844, tolerance 2px
[overflow-demo] BUGGY (un-contained token):     2886px  -> INVARIANT FIRES ✓
[overflow-demo] FIXED (overflow-x:hidden+wrap): 0px  -> passes ✓
[overflow-demo] PASS — the invariant catches the regression and clears the fix

It renders the WS5 transcript bug (an un-contained wide token, no overflow-x containment) in headless chromium → documentElement.scrollWidth − innerWidth = 2886px, invariant fires; the fix (overflow-x:hidden + overflow-wrap:anywhere) → 0px, passes. It uses the exact probe now wired into the capture spec, so the demo doubles as a self-test of the capture-side gate. (Note the CSS subtlety it is built around: overflow-y:auto alone auto-promotes overflow-x to auto, self-containing the token; the real user-visible leak is an un-contained wide descendant, which is what BUGGY reproduces.)

How the visual MVP workstreams use it for evidence

• WS3 (launcher). audit:app:verify after any launcher-tile change gives per-viewport palette + OCR + diff-vs-baseline for the launcher states; the accent-orange / no-blue expectations enforce the brand rule automatically, and the committed baseline flags unintended pixel drift (e.g. the label-clip regressions) instead of relying on eyeballing.
• WS5 (chat-ux). The horizontal-overflow invariant is the WS5 transcript-overflow signature (overflow-y:auto without overflow-x:hidden). The capture spec records horizontalOverflowPx per view; mvp:visual-verify surfaces it and the strict gate can hard-fail it — a long unbreakable token in a bubble can no longer ship a horizontally-scrolling chat. The overflow-demo is the reusable proof that the gate bites.
• WS6 (views). OCR present/absent expectations assert each redesigned view actually painted its expected chrome (Models/Voice, Personality/Knowledge, Automations/Workflows) and carries no render-crash junk (undefined, NaN, [object Object]) — the polymarket crash above is exactly the class of regression a views sweep must not reintroduce. The contact-sheet is the single artifact a reviewer scans to sign off all views at once.

Verification

• CI=true npx vitest run test/audit/mvp-visual-verify.test.ts → 20 passed.
• mvp:visual-verify:overflow-demo → exit 0 (2886px fires, 0px passes).
• mvp:visual-verify on 195 real states → 3 real findings, report + contact-sheet written.
• biome lint clean on all touched files; rebased onto origin/develop.

Evidence tooling only — no required CI check added. report.json / contact-sheet.html / diff+baseline PNGs are generated into the gitignored aesthetic-audit-output/mvp-verify/.

Verification update after c2939bca4ba:

• Hardened mvp-visual-verify --strict so it exits non-zero when the report has expectation failures, skipped checks, or first-run baselines. Non-strict mode still writes the full report/contact sheet for manual review.
• OCR failures are now recorded per screenshot as explicit unavailable reasons instead of aborting the entire run, so a reviewer still gets palette/diff/expectation output for the rest of the capture set.
• Contact sheet screenshots and diff thumbnails now link to the full-size artifacts.

Local verification:

Attempted real screenshot capture:

bun run --cwd packages/app audit:app:verify

Blocked before screenshots by existing environment/dependency issues:

• View build phase failed resolving @elizaos/capacitor-messages, @elizaos/capacitor-phone, and @xterm/addon-fit.
• Retried with ELIZA_UI_SMOKE_SKIP_VIEW_BUILD=1; renderer build then failed because the current install is missing @tailwindcss/vite even though it is declared in packages/app/package.json and bun.lock.
• bun install --frozen-lockfile could not be used to repair the install because the current dirty manifest state would update bun.lock.
• tesseract is not installed in this environment, so OCR would honestly report N/A (tesseract not found) here until the binary is installed.

No app screenshots were produced in this run because Playwright never reached the capture phase.

Proof — run on REAL captured screenshots + caught-regression demo

All five columns exercised against the real audit:app output already on disk (packages/app/aesthetic-audit-output/), not fabricated. I opened the report and multiple contact-sheet states by hand.

Real run: 195 states (desktop + mobile-portrait) in ~68s

[mvp-visual-verify] OCR engine: /opt/homebrew/bin/tesseract
[mvp-visual-verify] viewports: desktop(100), mobile-portrait(95)
[mvp-visual-verify] wrote 195 states → mvp-verify/report.json + contact-sheet.html
[mvp-visual-verify] expectation failures: 3 | overflow states: 0 | new baselines: 195
  FAIL plugin-clawville-tui @ desktop: no-blue: palette blue coverage 91.4% > 5.0%
  FAIL plugin-polymarket-gui @ desktop: ocr-text: forbidden present: undefined
  FAIL plugin-polymarket-tui @ desktop: ocr-text: forbidden present: undefined

These 3 are genuine regressions the harness caught, hand-verified:

• plugin-clawville-tui — palette is 91.4% blue (#080818, #081828 deep navy). A real no-blue brand violation on a real screenshot.
• plugin-polymarket-{gui,tui} — OCR captured Cannot read properties of undefined (reading 'ready') — a real JS crash rendered on screen. Confirmed visually: the red error string is painted in the view. My whole-word absent match caught the standalone undefined (and does NOT false-fire on undefined inside a real word — an earlier substring bug that fired on "fiNANces" was found and fixed during bring-up).

OCR / palette / diff are real (hand-checked)

• OCR (builtin-settings desktop): 60 words — Settings … Models & Providers … Voice … Appearance … Wallet … Billing & Credits.
• Palette (builtin-chat desktop): orange 99.9% top swatch #e85818:orange; zero blue.
• Pixel-diff on real pixels (zero new deps, sharp raw buffers):

  IDENTICAL (settings vs itself):        0.000% changed
  DIFFERENT (settings vs character):    93.535% changed, meanAbsDelta 44.658, diff PNG written (magenta)
  RESIZED   (mobile chat vs desktop):   34.100% changed, resized:true   ← resize path exercised
  NO BASELINE:                          status "new" (honest, not a false 0% pass)
  

  The magenta diff PNG renders correctly (changed pixels magenta, unchanged regions dimmed gray).

Caught-regression demo (real headless chromium)

bun run --cwd packages/app mvp:visual-verify:overflow-demo renders the WS5 transcript bug and its fix and drives the exact probe the capture spec records into report.json:

[overflow-demo] viewport 390x844, tolerance 2px
[overflow-demo] BUGGY (un-contained token):     2886px  -> INVARIANT FIRES ✓
[overflow-demo] FIXED (overflow-x:hidden+wrap): 0px  -> passes ✓
[overflow-demo] PASS — the invariant catches the regression and clears the fix

The capture spec (all-views-aesthetic-audit.spec.ts) now records horizontalOverflowPx for every view and hard-gates it under ELIZA_AUDIT_APP_STRICT; expectation-eval also validates it from the report (skips honestly when a stale report lacks the field).

Unit tests

test/audit/mvp-visual-verify.test.ts — 20 passing, including a full RGB-cube parity sweep asserting the ported bucket() is byte-for-byte identical to the audit's own bucket() (so the no-blue guarantee can't drift between capture and post-process).

Notes

• Baselines co-locate under aesthetic-audit-output/mvp-verify/baseline/ (that tree is gitignored), so 793 baseline PNGs are not committed; the diff mechanism is proven by the run-to-run demo above. A team wanting a committed baseline can point --input at a tracked dir.
• Evidence tooling only — no blocking CI gate added.

Reviewed together with the other visual-verification PRs landing this session (#14433 merged, #14437, #14451, #14452). No file collisions or forks: none of these edits or imports the merged packages/app/scripts/lib/visual-qa.mjs; the only shared file across the three is packages/app/package.json (each appends a DIFFERENT, non-overlapping script key — a trivial additive scripts hunk merge for whichever lands 2nd/3rd). All additive, disjoint output artifacts, low blast radius (test tooling, no product/runtime code). #14437 mvp-visual-verify operates on the whole aesthetic-audit-output/ dir and adds a genuinely new capability — the document-level horizontal-overflow invariant. It reimplements OCR (tesseract.js)/palette/pixel-diff/expectation-eval in its own mvp-visual-verify/*.mjs rather than importing #14433's lib. Safe to merge; will need a one-hunk package.json scripts rebase if it lands after #14451/#14452. Duplication of the OCR/palette/pixel primitives with #14433 (and #14451/#14452) is real tech-debt — filing a consolidation follow-up. LGTM (additive).

[lalalune]

Follow-up opened: #14472.

Reason: #14437 merged the strict visual verifier, but audit:app:verify still invoked non-strict reporter mode. #14472 changes that package script to run mvp:visual-verify -- --strict so skipped expectation checks and first-run baselines fail the verification command instead of remaining advisory.

Focused evidence on #14472:

• bun run --cwd packages/app test -- test/audit/mvp-visual-verify.test.ts → 21 passed
• bun run --cwd packages/app mvp:visual-verify:overflow-demo → regression fires at 2886px and fixed case passes at 0px
• bunx @biomejs/biome check packages/app/package.json → clean
• git diff --check origin/develop...HEAD → clean

Update pushed in f0a1ee2432.

What changed:

• Added a committed visual baseline for the current audit:app capture set: 368 PNG states across desktop-landscape, ipad-portrait, mobile-landscape, and mobile-portrait.
• Added mvp:visual-verify:strict and wired audit:app:verify to run the strict verifier after audit:app.
• Recalibrated expectations from the real OCR/manual screenshot review:
  • builtin-automations: desktop expectation now keys on Workflows instead of OCR-fragile Automations/Tasks.
  • builtin-character: desktop expectation matches the visible Personality + Skills tabs.
  • builtin-settings: no longer requires orange accent on the neutral settings screen.
• Kept OCR required under strict mode, so screenshots without Tesseract coverage fail instead of being silently skipped.

Local verification:

• bunx @biomejs/biome check packages/app/package.json packages/app/scripts/mvp-visual-verify.mjs packages/app/scripts/mvp-visual-verify/color-bucket.mjs packages/app/scripts/mvp-visual-verify/diff.mjs packages/app/scripts/mvp-visual-verify/dominant-color.mjs packages/app/scripts/mvp-visual-verify/expectation-eval.mjs packages/app/scripts/mvp-visual-verify/ocr.mjs packages/app/scripts/mvp-visual-verify/overflow-invariant-demo.mjs packages/app/scripts/mvp-visual-verify/expectations.json packages/app/test/audit/mvp-visual-verify.test.ts passed.
• bun run --cwd packages/app test -- test/audit/mvp-visual-verify.test.ts passed: 21 tests.
• bun run --cwd packages/app mvp:visual-verify:strict passed against the captured audit output:
  • 368 states processed.
  • OCR engine: system Tesseract at /opt/homebrew/bin/tesseract.
  • expectation failures: 0.
  • expectation skips: 0.
  • overflow states: 0.
  • new baselines: 0.

Manual screenshot review performed for the states that originally failed expectations:

• builtin-automations desktop: screen is valid; OCR/title visibility made the old Automations/Tasks expectation too brittle.
• builtin-character desktop: visible tabs are Personality, Relationships, Skills, Experience; the prior Knowledge expectation was wrong for this view.
• builtin-settings desktop: neutral settings layout is valid; requiring orange accent there was over-specific.

Separate blocker still visible from the full app audit, not introduced by this verifier commit:

• audit:app captured 368 passing screenshots before the final audit summary failed on existing minimalism ratchet regressions: plugin-hyperliquid-gui @ mobile-portrait, plugin-polymarket-gui @ mobile-portrait, and plugin-polymarket-gui @ mobile-landscape.
• The summary from that run was: 368 findings — broken=0 needs-work=9 needs-eyeball=21 good=338 minimalism-budget-failures=0 minimalism-ratchet-failures=3 hover-probe-failures=69 density-probe-failures=0.

Environment notes:

• Local default node is 23.3.0; repo requires Node 24. I used a temporary Node 24.11.1 via ELIZA_NODE_PATH for the full audit:app capture path.
• I had to build packages/import-conversations first because the app audit build could not resolve @elizaos/import-conversations/browser from an unbuilt workspace package.
