+# Handoff — 2026-07-28 · walkthroughs, CDP repair, motion-proof
+
+Written for the next engineer. Everything below was measured, not assumed; where something
+is unverified it says so. Three repos are involved, so read the **Landmines** section before
+touching anything.
+
+---
+
+## What shipped
+
+| Repo | PR | State |
+| --- | --- | --- |
+| FeatureClipStudio | [#6](https://github.com/HomenShum/FeatureClipStudio/pull/6) | **merged** 2026-07-29 |
+| NodeSlide | [#110](https://github.com/HomenShum/NodeSlide/pull/110) | mergeable, waiting on one CI check |
+| NodeRoom | [#244](https://github.com/HomenShum/NodeRoom/pull/244) | rebased onto main, CI re-running |
+
+### Three product defects, all found by filming the product rather than reading it
+
+1. **Every `FocusTrapDialog` modal rendered behind its own blur scrim.** Radix portals
+ overlay and content as *siblings*; the legacy scrims (`.r-modal-backdrop`,
+ `.r-room-modal-scrim`) were written to centre a *child*, and `FocusTrapDialog` passes
+ `unstyled`, which drops the Tailwind fixed/translate classes. Result: dialogs rendered
+ `position: static` at the end of `
`, under a z-95 blur — including the create-room
+ dialog carrying the product's one governance question. Fixed in `src/app/styles.css` by
+ positioning `[data-slot="dialog-content"]` itself, plus a real `.sr-only` (Tailwind's is
+ absent from this bundle, so the fallback `DialogTitle` printed the word "Dialog" on every
+ modal).
+ **DOM text extraction read these dialogs correctly the whole time.** Only frame review
+ caught it.
+
+2. **CDP scripts were killing the developer's real browser.** `browser.close()` on a
+ `connectOverCDP` connection closes *Chrome*, not the socket — so every script killed the
+ browser the next one needed. Swept the class: 9 pure-CDP scripts drop the call;
+ `scripts/motion-inventory.mjs` connects *or* falls back to `launch()`, so it tracks
+ `weLaunchedIt` and closes only what it owns. Separately `scripts/chrome-cdp-up.ps1` used
+ `Stop-Process -Force`, which is what produced *"Chrome didn't shut down correctly"* and lost
+ tabs; it now closes gracefully with `CloseMainWindow()`.
+
+3. **The upload verifier asserted videos that no longer exist.** `yt-verify.mjs` hardcoded two
+ ids that are now Private, and matched titles on a phrase the superseded clip *and its
+ replacement* both carry — so it could pass against the wrong video. Root cause was two
+ copies of the roster free to disagree. Now one `scripts/yt-roster.mjs` that both the
+ verifier and the privatize guard import, and the verifier checks **both directions**:
+ 6 published must resolve, 4 superseded must be refused.
+
+### `skills/motion-proof` — vendored into this repo on purpose
+
+It previously lived only in `~/.claude`, which is **not version controlled**, so it could not
+be handed to anyone. It now sits beside `skills/liveflow`, `skills/probe-first`, etc.
+
+```bash
+node skills/motion-proof/motion-probe.mjs # the deception corpus
+node skills/motion-proof/motion-probe.mjs --subject "" --nudge
+```
+
+An audit found this skill **inverted in practice**: its `SKILL.md` correctly names
+`Element.getAnimations()` primary and the video judge advisory, but `getAnimations()` had
+**zero executable callers** while six Gemini video-judge scripts shipped. `motion-probe.mjs`
+is the missing primary instrument. It ships with 7 adversarial fixtures + an honest control;
+the control must pass and every deception must be caught, and running it the first time
+found two false positives in the probe itself.
+
+---
+
+## Landmines
+
+- **`~/.claude` is not a git repo.** `skills/motion-proof` is now vendored here, but the
+ *other* skills there (`design-dna`, `graph-hop`, `second-brain`, `trust-surfaces`,
+ `motion-ladder`) exist on one machine with no history and no backup. If they matter,
+ they need a home.
+- **PR #244 was stacked on `codex/nodekit-contract-alignment`.** That branch's own PR (#241)
+ fails `NodeSlide packed consumer`, `node-platform / conformance`, and `verify` — the same
+ three failures #244 inherited. It has been rebased onto `main` and those failures left with
+ it. **Do not re-branch from `codex/*` without checking its PR is green first.**
+- **Two conflicting PRs remain open in NodeRoom** — #190 (`codex/mobile-terracotta-launch`)
+ and #182 (`codex/proofloop-strict-live-official`), both `CONFLICTING`. Not touched; not mine.
+- **`.qa/memory/findings.jsonl` had an unresolved stash conflict** (`UU`). Both sides were
+ distinct valid records in an append-only log, so the resolution kept the **union** — 29
+ records, all parsing. If you expected one side to win, check that.
+- **Never render video live in a demo.** Image generation returns in seconds; video takes
+ minutes and fails often.
+- **Deferred boot.** `boot.ts` defers the app module until first interaction, so an
+ unhydrated SSR shell is a *different page* from the React landing — different markup, and
+ the join-code control is inline rather than a dialog. Any probe or capture must nudge and
+ wait for a React-only element, never a timer. This is why `motion-probe` has `--nudge`.
+
+---
+
+## The pattern worth inheriting
+
+The same defect appeared five times today in unrelated places: **a hand-typed value describing
+a version of the artifact that no longer exists.**
+
+- a YouTube title reading "11s walkthrough" over a 24-second video
+- `METADATA.md` recording pre-recut durations
+- showcase GIFs rendered from superseded captures
+- the verifier's hardcoded video ids
+- the roster existing twice, free to drift
+
+Every fix was the same shape: **derive the value at write time, or keep exactly one copy.**
+`yt-upload.mjs` now derives durations via `ffprobe`; `yt-roster.mjs` is the single roster.
+
+A second, sharper version of it: **a decision recorded only in a conversation will be
+re-decided by the code.** A council verdict to delete NodeSlide's Design tab as a standalone
+destination is not done, is recorded nowhere in that repo, and the most recent inspector
+commit reinforced the tab strip instead. Verdicts that survive must land in the repo they
+govern — as a test, an invariant, or at minimum a dated note.
+
+---
+
+## Verification habits used here (and why)
+
+- **Verify the claim the artifact makes, not that the artifact exists.** Frame counts, byte
+ sizes and HTTP 200s all passed while the clips showed another product's URL.
+- **Probe gates in both directions.** A gate only ever seen passing is not known to work. The
+ privatize guard was tested by feeding it a keeper and confirming it refused, *before* it was
+ aimed at real targets.
+- **Verify from the public surface.** `git push` exiting 0 is not evidence; fetch the raw URL
+ and grep for a content signal.
+- **State coverage, don't imply it.** Artifacts carry `touched/total`, and `JOURNEYS.md`
+ records 10 of 13 journeys shot with the remaining three named, one of them explicitly
+ declined by the owner rather than missed.
+
+---
+
+## Open, not done
+
+- NodeSlide #110 and NodeRoom #244 need a human to confirm the merge once CI is green.
+ NodeSlide's repo does not allow auto-merge, and `--admin` would bypass a branch-protection
+ rule that was set deliberately — so it was not used.
+- `ScoreReceipt` (third link of `ReferenceObservation → DesignRule → ScoreReceipt`) was being
+ emitted by a parallel agent when this was written; confirm it landed and that its schema
+ validates the existing records unmodified.
+- The 7 deception fixtures are runnable but are not yet wired into CI. They should be — that
+ is what turns the corpus from a demonstration into a gate.

+### The NodeRoom walkthrough clips — three ways in
+
+Three clips are published. Lengths are `ffprobe` readings of the source renders, not estimates:
+
+| Clip | Length | Audio | Journey |
+|---|---|---|---|
+| [NodeRoom — review every agent change](https://youtu.be/3N7sBxFLFOc) | 24s | silent | R1 — the `#story` no-clobber drills |
+| [NodeRoom — from landing to a room](https://youtu.be/qpzHP5-pWvw) | 17s | silent | R2 + R3 — hydrated landing → create a room → join by code |
+| [NodeRoom — the full walkthrough, narrated](https://youtu.be/uvXf7e4hwt4) | 79s | local-TTS voiceover | R1 + R2 + R3 in one continuous pass |
+
+
+The 17s fresh-user clip inline, because GitHub does not play video in a README. Rendered from the same source MP4 with this repo's two-pass palette recipe ([`scripts/walkthroughs/render.ts`](scripts/walkthroughs/render.ts): `fps=12`, 896px lanczos, `palettegen stats_mode=diff` → `paletteuse` bayer/`diff_mode=rectangle`). Filming it found and fixed a shipped regression: after the Radix migration every `FocusTrapDialog` modal rendered *behind* its own blur scrim. The hydrated React landing also turned out to be a different page from the SSR shell — join is an inline control there, not a dialog.
+
+**Coverage, honestly.** These three cover **3 of the 6 NodeRoom journeys** on the journey map (R1 drills, R2 create-a-room, R3 join-by-code); across both products the tally is **10 of 13 journeys shot, 0 reachable and unshot**. The two unfilmed NodeRoom journeys share one root cause, not two: **R5** (in-room review/approve — the product's core journey) and **R4** (mobile approver) both need a signed-in, seeded live room, and R5 is **declined by the owner** ("no seed room") rather than missed. **R6** is not a distinct journey after probing — the `#story` "Architecture" button navigates within the page already filmed in R1. At element level the R1 capture touches **6/21 elements** on an 8,570px surface with 17 controls: a journey clip, not a control sweep.

+ * dependency tree has traded the claim for a bundle.

+ * The important half is the failure mode. A missing browser must fail CLOSED and loudly. The
+ * tempting alternative — skip the check, report nothing, exit 0 — is precisely the vacuous pass
+ * (docs/VACUOUS_PASS.md): a green result from an instrument that measured nothing. "No browser, so

+ * #title-textarea #textbox; /edit uses a bare div#textbox distinguished only
+ * by aria-label. Guessing three times cost more than probing once.

+ * 2. Launch Chrome with --disable-extensions. A real profile loads ~13 extension

+ * — the websocket connects, then times out. Cookies live in the profile, not

+name: motion-proof
+description: Verify that shipped motion does what its spec claims — rubric-driven video judgment plus the knockout test — instead of accepting "the animation works" as a vibe. Use after any motion change (motion-ladder rung 2+), before claiming an interaction "feels right", when a demo recording exists or should, or when reduced-motion compliance needs proof. Extends the feature-walkthrough-gif pipeline and the Gemini video judge with a rubric derived from the declared tokens, and refuses to pass motion that was never observed running.
+---
+
+# motion-proof
+
+A motion claim without a runtime observation is a screenshot of a dance. CSS can be grepped and
+still never fire; a timeline can compile and be dead; reduced-motion can "exist" in a media query
+that no browser was ever asked to evaluate. This skill is the gate that makes motion claims cost
+something.
+
+Sibling of motion-ladder: **the ladder decides what motion may exist; this proves the motion that
+exists does what was declared.**
+
+## Instrument hierarchy — deterministic FIRST, video judge SECOND
+
+Corrected 2026-07-28 by council (NK-Mom's-Biz). The first draft of this skill made the video judge
+the primary instrument. That was wrong: **it is the correct perceptual secondary judge, and not the
+strongest primary instrument.** A video is a re-observation of something the browser already knows
+precisely.
+
+**Primary — deterministic, and they decide pass/fail:**
+
+ Element.getAnimations() what is actually animating, right now, with real timings
+ Web Animations API timing declared vs effective duration/easing/delay
+ animationstart/end, transitionrun/end did it fire at all
+ PerformanceObserver + long-task observer, rAF sampling frame cost
+ DOM mutation timeline · focus event timeline
+ GSAP adapter callbacks · Three.js renderer statistics
+ Playwright trace · final DOM/state hashes
+
+`Element.getAnimations()` is the instrument that answers "did the animation actually run" without
+a single frame of video, and it is the one this skill should reach for first.
+
+**Secondary — the judge answers only what deterministic tools answer badly:**
+does the sequence communicate causality · does the transition feel discontinuous · does motion
+compete with the primary task · is the authored motion coherent across the page · does a slide
+build reveal the argument in the intended order.
+
+**The judge must never override** a trust-surface violation, a missing reduced-motion state, a
+performance failure, a wrong choreography order, an absent animation, or a failed knockout. Those
+are deterministic verdicts and a compliment does not outrank them.
+
+**Never emit one blended "motion score."** A receipt reports the layers separately:
+
+ Deterministic proof: PASS
+ Video semantic judge: 3/4
+ Human review: pending
+
+A single number hides which layer failed, which is the same defect as a coverage percentage that
+cannot say what was never run.
+
+## Run it — `motion-probe.mjs` is the primary instrument
+
+Added 2026-07-28. Until then this section did not exist and `Element.getAnimations()` had **zero
+executable callers** — three hits in the whole tree, all of them prose in markdown — while six
+working Gemini video-judge scripts shipped. The instrument this skill calls secondary was the only
+one that ran. A skill documenting rigour it does not perform is a vacuous pass about vacuous passes.
+
+```bash
+node ~/.claude/skills/motion-proof/motion-probe.mjs # run the deception corpus
+node ~/.claude/skills/motion-proof/motion-probe.mjs --subject "" --nudge
+```
+
+- `--subject` declares what is under test. Animations are bound to it, because a page-wide count is
+ exactly what the off-screen-decoy fixture defeats. Real products do not carry `[data-subject]`.
+- `--nudge` scrolls once before sampling, for deferred-boot apps that serve an SSR shell until first
+ interaction — probing that shell and reporting "no motion" is a true statement about the wrong page.
+- `--knockout` is **opt-in**: `?knockout=scrub` is a convention the subject must implement. Firing it
+ at a product that never heard of it navigates nowhere and reports a timeout as a motion finding.
+- An unrecognised flag **throws**. A runner that silently skips a typo'd instruction produces a clean
+ report of something it never did.
+- Playwright resolves from the consuming repository, never from `~/.claude`, and a missing browser
+ **fails closed**. Not-run is never a pass.
+
+Hidden and off-subject animations are counted and reported **separately**, never folded into the
+total — `getComputedStyle` reports `animationName` inside `display:none` subtrees.
+
+The corpus is self-testing: the control must PASS and every deception must be CAUGHT. Running it the
+first time found two false positives in the probe itself — it rejected the honest control because
+enter animations start at `opacity: 0` (so opacity is not a paint test), and because it compared
+`transform: none` against the identity matrix as if they were different final states. A corpus with
+no honest control only proves an instrument can say no.
+
+## The rubric rule (what makes the judge honest)
+
+The video judge is only as good as its question. "Does this look good?" returns a compliment. The
+rubric is **derived mechanically from the motion spec**, so every question is checkable:
+
+ declared: modal-enter 240ms ease-out-expo, opacity + 8px translate
+ rubric: 1. Does the modal enter in a single motion ≤300ms?
+ 2. Does it move up (not down, not scale)?
+ 3. Is there any content flash before the motion starts?
+
+ declared: list stagger 35ms/item bottom-up
+ rubric: 4. Do list items appear in sequence, not simultaneously?
+ 5. Is the order bottom-up?
+
+If a question cannot be derived from a declared token or choreography line, it does not go to the
+judge — it goes back to the spec as a gap.
+
+## Floor
+
+1. Capture the flow with the feature-walkthrough-gif pipeline (its 13 capture lessons apply
+ unchanged — timing, viewport, settle-waits).
+2. Derive the rubric from the motion spec / declared tokens.
+3. Run the video judge with the rubric. Every answer cites a timestamp.
+4. **Reduced-motion pass:** re-capture with `prefers-reduced-motion` emulated in the real browser.
+ Verify it collapses to the FINAL state — per motion-ladder, a reduced-motion path that shows a
+ different design is a failure, not a variant.
+5. Verdict per rubric line: pass / fail / not-observed. **not-observed is never pass.**
+
+## Ceiling — the knockout test (causality, not correlation)
+
+Borrowed from NodeSlide's knockout gate: remove the thing, re-render, and require the difference
+to be the *claimed* difference.
+
+**The obvious implementation is a gaming route — do not use it.** The first draft of this skill
+specified GSAP `timeScale(0)` + jump-to-end. Council (Slide-AI, the thread that designs adversarial
+gates) named that as a known deception: **a knockout that jumps to the end falsely passes**, because
+the final state is exactly what the un-knocked-out run also produces. The knockout must remove the
+*mechanism*, not fast-forward it — prevent the timeline from being constructed at all (stub the
+adapter, refuse the import, unmount the driver), then observe.
+
+- Re-run the capture with the timeline **never constructed** — adapter stubbed at the seam, not
+ scrubbed to its end state.
+- Diff the two recordings. The delta must be exactly the declared motion — if the page looks the
+ same, the motion never ran (dead code passing review); if MORE differs than declared, something
+ undeclared is animating (an unnamed owner, which motion-ladder forbids).
+- Perceptual thresholds on canary pixels for the imperceptible-change and no-op routes — the two
+ gaming routes the OOXML gates deliberately left to a runtime instrument. The web is where that
+ instrument is cheap.
+
+## The Motion Deception Corpus (fixtures this skill must beat)
+
+Named by council 2026-07-28. Every gate needs the list of things built to beat it, or it is a gate
+nobody attacked. Each of these passes a naive motion check. **All seven are now runnable pages in
+`fixtures/`, plus an honest control** — until 2026-07-28 this was a list of seven strings and zero
+files, which is a specification of an adversarial suite nobody built:
+
+ 00-honest-control.html the control — motion that is real, on the declared subject
+ 01-exists-but-never-mounts.html perfect CSS, element never inserted
+ 02-offscreen-decoy.html getAnimations() returns 1; it belongs to nothing visible
+ 03-clock-only-diff.html pixel-diff passes on a ticking clock; nothing animated
+ 04-trust-surface-toward-approval.html undecided proposal animates into the language of acceptance
+ 05-reduced-motion-different-design.html query honoured, but a second design is rendered
+ 06-knockout-jumps-to-end.html timeline scrubbed to end instead of never constructed
+ 07-video-shows-absent-motion.html the GIF shows a shimmer; the page has no animations at all
+
+Note the fourth and the sixth. The fourth is the trust-surfaces violation in its most dangerous
+form — motion that moves *toward* apparent approval. The sixth was a defect in this skill's own
+first draft, which is the argument for keeping the corpus: the gate's author is not exempt from it.
+
+**These are instances of the vacuous pass** — a green result from an instrument that measured
+nothing. The general tell, which catches routes not yet in the corpus:
+
+> Ask of any green result: **what would this have reported if the subject did not exist?**
+> If the answer is "the same thing," the check is vacuous and its green is worth nothing.
+
+Two more from the same class, outside motion, worth guarding against in any runner this skill
+drives: `getComputedStyle` reports `animationName` for elements inside `display:none` subtrees, so
+filter for **painted** visibility and report hidden counts separately rather than folding them in;
+and an **unrecognised instruction must fail, never no-op** — a capture runner that silently skips a
+typo'd action produces a recording of a frozen viewport that looks exactly like a successful one.
+
+## `profiles/genjutsu.yaml` — the adversarial profile
+
+Genjutsu is an illusion technique, and that is exactly the failure this profile hunts: **motion
+that produces a persuasive visual impression of progress, causality, or completion without the
+underlying state actually changing.** Named by council 2026-07-28, which ruled it should be a
+profile here rather than a sixth overlapping system — the vocabulary without the architecture.
+
+Checks in the profile:
+
+- **timeline knockout** — disable it, re-render, diff must equal the claimed difference
+- **frozen-frame comparison** — first and last frames against the declared start/final states
+- **reversed choreography** — if reversing the order changes nothing a user can name, the order
+ was never carrying information
+- **reduced-motion equivalence** — same final state, not a second design
+- **removal of decorative layers** — does comprehension survive without them
+- **task completion with and without motion** — the strongest signal available
+- **apparent progress with no state transition** — a spinner, sweep, or fill that animates while
+ nothing behind it advanced. This is the trust-surfaces class in motion form: a failure that
+ animates like a loading state is lying about which state the system is in.
+
+## Forbidden-surface sweep
+
+One structural check per run, independent of the rubric: **no motion on trust-decision surfaces**
+(`proposal`, `conflict`, `failed_safe`, any diff/review surface). A transition found there is a
+correctness finding at any duration, per motion-ladder — it can make a not-yet-accepted change
+feel accepted.
+
+## What this refuses
+
+- Passing motion nobody watched run ("the CSS is correct" is a spec claim, not a proof).
+- A rubric written from taste instead of the spec.
+- Reduced-motion verified by grep.
+- A single recording standing in for both motion and reduced-motion paths.
+
+## Composes with
+
+- **motion-ladder** — proves the rung's claims; PROOF.md for rung 6 cites these runs.
+- **easier-to-read-submissions** — the demo recording it already requires becomes the capture.
+- **agentic-ui-qa** — persona runs double as capture sessions.
+- **before-after-proof** — the before-capture is the baseline the knockout diffs against.

+# genjutsu — the adversarial profile for motion-proof
+#
+# Referenced by SKILL.md:132 since this skill was written; the file did not
+# exist until 2026-07-28. A skill that names a profile it does not ship is
+# itself an instance of what this profile hunts: a persuasive impression of
+# rigour with nothing behind it.
+#
+# Genjutsu is an illusion technique. The failure this profile hunts is motion
+# that produces a convincing visual impression of progress, causality, or
+# completion WITHOUT the underlying state actually changing.
+#
+# Council 2026-07-28 (NK-Mom's-Biz x Slide-AI) ruled genjutsu is a PROFILE here,
+# not a sixth overlapping system — the vocabulary without the architecture.
+# Slide-AI's public name for the fixture set is "Motion Deception Corpus".
+
+version: 1
+name: genjutsu
+summary: >-
+ Motion that looks like progress while state stands still. Every check below
+ answers the general tell: what would this have reported if the subject did
+ not exist? If the answer is "the same thing", the green is worth nothing.
+
+# The instrument order is not negotiable and is the reason this profile exists.
+# Corrected 2026-07-28: the first draft made the video judge primary. A video is
+# a re-observation of something the browser already knows precisely.
+instruments:
+ primary: # these decide pass/fail
+ - Element.getAnimations()
+ - Web Animations API timing (declared vs effective)
+ - animationstart/end, transitionrun/end
+ - PerformanceObserver long-task + rAF sampling
+ - DOM mutation timeline
+ secondary: # advisory only, never overrides primary
+ - video semantic judge
+ never_blend: true # no single "motion score" — layers reported separately
+
+checks:
+ - id: timeline-knockout
+ intent: Remove the mechanism, re-render, and require the delta to equal the claimed difference.
+ method: >-
+ Stub the adapter at the seam / refuse the import / unmount the driver so the
+ timeline is NEVER CONSTRUCTED. Then diff.
+ forbidden_implementation: >-
+ GSAP timeScale(0) or any jump-to-end / progress(1) scrub. Council named this a
+ known deception: the final state is exactly what the un-knocked-out run also
+ produces, so the knockout falsely passes. This was a defect in this skill's own
+ first draft — the gate's author is not exempt from the corpus.
+ fails_when:
+ - page is identical with the mechanism removed # motion never ran; dead code passing review
+ - more differs than declared # something undeclared animates; motion-ladder forbids unnamed owners
+
+ - id: frozen-frame-comparison
+ intent: First and last frames against the DECLARED start and final states.
+ fails_when:
+ - final state does not match the declared end state
+ - content flashes before the motion starts
+
+ - id: reversed-choreography
+ intent: Reverse the order; if nothing a user can name changes, the order carried no information.
+ fails_when:
+ - reversing the sequence produces no nameable difference
+
+ - id: reduced-motion-equivalence
+ intent: prefers-reduced-motion must collapse to the SAME final state.
+ method: Emulate in the real browser. Never verify by grep.
+ fails_when:
+ - reduced-motion path shows a DIFFERENT design (a failure, not a variant)
+ - one recording is offered as proof of both paths
+
+ - id: decorative-layer-removal
+ intent: Does comprehension survive without the decorative layers?
+ fails_when:
+ - removing decoration changes what the user can understand
+
+ - id: task-completion-with-and-without
+ intent: The strongest signal available — can the task be completed either way?
+ fails_when:
+ - the task is only completable with motion running
+
+ - id: apparent-progress-no-state-transition
+ intent: >-
+ A spinner, sweep, or fill that animates while nothing behind it advanced.
+ The trust-surfaces class in motion form: a failure that animates like a
+ loading state is lying about which state the system is in.
+ fails_when:
+ - an indicator animates while its underlying state is unchanged
+ - a failed operation renders as an in-progress affordance
+
+# One structural check per run, independent of the rubric.
+forbidden_surface_sweep:
+ surfaces: [proposal, conflict, failed_safe, diff, review]
+ rule: >-
+ No motion on trust-decision surfaces. A transition found here is a correctness
+ finding AT ANY DURATION — it can make a not-yet-accepted change feel accepted.
+ severity: correctness
+
+# Runner obligations. Both were real defects found in this session's own tooling.
+runner_requirements:
+ - id: painted-only
+ rule: >-
+ getComputedStyle reports animationName for elements inside display:none
+ subtrees. Filter for PAINTED visibility and report hidden counts SEPARATELY
+ rather than folding them into the total.
+ - id: unknown-instruction-must-throw
+ rule: >-
+ An unrecognised instruction must FAIL, never no-op. A capture runner that
+ silently skips a typo'd action produces a recording of a frozen viewport that
+ looks exactly like a successful one.
+
+# The fixtures this profile must beat. Each passes a naive motion check.
+# Implemented as runnable pages in ../fixtures/ — a corpus that is only a list
+# is a gate nobody attacked.
+deception_corpus:
+ - id: never-mounts
+ fixture: fixtures/01-exists-but-never-mounts.html
+ deception: CSS animation is declared but the element is never mounted.
+ - id: offscreen-decoy
+ fixture: fixtures/02-offscreen-decoy.html
+ deception: The animation targets an off-screen decoy, not the visible subject.
+ - id: clock-only-diff
+ fixture: fixtures/03-clock-only-diff.html
+ deception: Screenshots differ only because a clock ticked; nothing animated.
+ - id: trust-surface-toward-approval
+ fixture: fixtures/04-trust-surface-toward-approval.html
+ deception: >-
+ An undecided proposal animates toward apparent approval. The most dangerous
+ form — motion moving a not-yet-accepted change toward feeling accepted.
+ severity: correctness
+ - id: reduced-motion-different-design
+ fixture: fixtures/05-reduced-motion-different-design.html
+ deception: prefers-reduced-motion renders a different design, not the same final state.
+ - id: knockout-jumps-to-end
+ fixture: fixtures/06-knockout-jumps-to-end.html
+ deception: >-
+ The knockout scrubs the timeline to its end instead of preventing construction,
+ so the "without motion" run produces the same final state and falsely passes.
+ - id: video-shows-absent-motion
+ fixture: fixtures/07-video-shows-absent-motion.html
+ deception: >-
+ A prerendered video/GIF of motion the live application does not contain.
+ Deterministic instruments see no animations; only the video judge is fooled —
+ which is the entire argument for the instrument order above.
