* fix(cli): fingerprint textual sweep state * fix(cli): share one motion classifier between sweep guard and liveness The frozen-sweep guard (sweep_static) and keepsMoving liveness (motion_frozen) each owned their own definition of "what counts as motion": the sweep fingerprint in layout-audit.browser.js read nine channels while motion-sample.browser.js compared box + opacity only. They meet in one decision in checkPipeline.ts, so a fixed-width attr() countdown was accepted by the sweep guard and still reported frozen by liveness. Move the classifier into motion-signature.browser.js, injected before both samplers, and make it the single owner: - Per-element channels (box, opacity, font-variation axes, clip-path, direct text, form-control state, ::before/::after content, media pixels) as a reader list so further channels (e.g. SVG dash) plug in. - Liveness consumes the same signature with 2px / 0.08 bucketing; the sweep guard consumes it exact. motion-sample throws at install if the shared script is missing. - Counter state is a composition-level channel over box-generating elements and root ancestors. display:none subtrees generate no boxes and are excluded, and only declarations naming a counter that some painted generated content (::before/::after/::marker on a non-ignored, paintable host) consumes are folded in, so a decoy hidden counter cannot make a frozen composition read as live. - clip-path is a channel, replacing the fingerprint's former reliance on the clipped-away visibility probe, so a wipe over a static box still counts. - data-layout-ignore layers are excluded from the signature but not from the per-selector `visible` bit reported for explicit motion assertions. - Root resolution for the "*" liveness scope now matches the sweep guard and the root element is part of its own signature. Tests: motion-signature.browser.test.ts (happy-dom, per-element fake computed style so ancestor handling comes from the classifier) and motion-signature.browser.chromium.test.ts (real Chromium via puppeteer-core; skips without a system browser) pin every branch: attr() substitution, display:none decoys, named-counter gating, ::marker, zero-box hosts, ancestor counters, textarea/indeterminate, root text, clip-path, ignore layers, and sweep/liveness agreement on the countdown fixture.

Pruning is now platform-owned where checkVisibility exists (display:none, skipped hidden/auto contents; a display:contents host keeps its painting pseudo-elements), with the computed-style fallback for happy-dom. A content-visibility:hidden host signs its own box, opacity, clip-path, font axes, and widget state, but not its text, pseudo content, control value, or media pixels; hosts where size containment does not apply (non-atomic inline, display:contents, table and internal table boxes, ruby) skip nothing. isVisibleElement regains the checkVisibility floor layout-audit uses on its opacity-floor path, so an asserted selector inside skipped contents reports hidden. The layout-audit opt-out no longer applies to the element passed as the signature root: a keepsMoving scope that is itself data-layout-ignore is measured (an assertion naming an element outranks the opt-out) instead of producing an empty signature that motionAudit reports as a missing selector. Opt-outs inside the scope still apply. motion-sample defers the missing-classifier error to the first call so the driver's evaluate surfaces it instead of an opaque "is not a function" page error; round() is shared. The real-Chromium suite is opt-in on Windows (HYPERFRAMES_BROWSER_TESTS=1): in the shared Windows package lane the runner's Chrome did not launch within the package hookTimeout, and the suite already runs on Linux CI where the system Chrome is found. The launch hook has its own 120s ceiling.

The parent's skipsContents verdict now prunes it; boxed descendants keep being decided by the platform. NOT_CONTAINABLE_DISPLAY had table-cell and table-caption inverted versus Chromium 152, where a table-cell host skips its contents and a table-caption host paints them. Four Chromium pins: the display:contents-in-skipped-contents counter, a table-cell host's own text and pseudo content (frozen), a table-caption host's own text and pseudo content (motion), and a counter reachable only through a skipped host's hidden ::marker / ::after (frozen; also asserts the skipped child is not visible for motion-sample).
