From 0b51cbd2edb4d24f7645452206801dec132eee0a Mon Sep 17 00:00:00 2001 From: Mike Babb Date: Thu, 4 Jun 2026 17:33:07 -0400 Subject: [PATCH 1/7] =?UTF-8?q?feat(tranche-C=20W1):=20the=20close=20made?= =?UTF-8?q?=20honest=20=E2=80=94=20inv=20=CE=B5's=20first=20application?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Makes B's seven asserted-not-met gates TRUE + biting, each re-verified by a checked-in, re-runnable instrument that passes (the integrity foundation C exists to establish). No engine source touched; the design/dogfood waves build on a now-honest close. S1 — real
landmark (EditorShell.vue): route (a) —
occupies the grid's center cell; display:contents (which stripped both the box AND the implicit landmark role) is gone, the aria-label band-aid dropped. Byte-identical layout, real landmark in the a11y tree. S2 — occlusion gate HARD + controls-OPEN axis (occlusion-gate.mjs + scripts/lib/demo-driver.mjs): dock-over-content promoted from advisory note to a failing assertion (content-rect intersection, per-scene dockFloatAllowed); both controls:{closed,open} axes; verified reddens on KF_OCCLUSION_INJECT=cube. One real occlusion surfaced (square/mobile) → NAMED W2_PENDING_OCCLUSION allowance with a self-cleaning stale-check (removal trigger: W2 mobile work-area/dock-reserve fix), NOT a silent exemption. S3 — π RM probe + contrast (capture.mjs): --reduced-motion captures 6 frames/ scene over the named window, asserts final-frame non-empty, emits a per-surface contrast table; the hard rest-frame assertion is gated behind KF_RM_HONORED=1 (default off) — flips true at W3 when the demo honors reduced-motion. S4 — the >50ms LoAF bench gate (playwright.bench.ts + bench/loaf-scene.html): the expect(true) stub is gone; the gate drives a 200-cell AnimationGroup composite, reads window.__kfLoaf, and fails on >50ms main-thread blocking — the observer's real 2nd consumer (overfitting closed). Wired into ci.yml. S5 — inv β reconciled honestly (package-lock + W6.md + FINAL.md + ci.yml): disposition (b) — npm tolerates the dangling optional ../glass-ui link non-fatally and the library graph never dereferences it; the false 'cleanly skips' / 'glass-ui-absent lockfile' prose corrected to the artefact. S6 — lighthouse A11y(demo-owned)=100 + SEO≥90 open-panel gate (lighthouse-gate.mjs + ci.yml): drives the OPEN-panel editing state (not the splash); HARD on any a11y audit outside two NAMED allowance buckets (bucket-glassui → ASK-3; bucket-w2 {image-alt,color-contrast} → W2) + SEO<90. Full A11y=100 binds when bucket-w2 empties at W2. CI stays green W1→W2. All gates verified locally green; the three deferred hard-assertions (π RM rest-frame → W3; A11y=100-full + square/mobile occlusion → W2) are NAMED with removal triggers, not silently passed. Part of the constellation dock+animation convergence (HUB/docs/constellation/DOCK-ANIMATION-CONVERGENCE.md). --- .github/workflows/ci.yml | 51 +- bench/loaf-scene.html | 180 ++++++ bench/playwright.bench.ts | 332 +++++++++-- .../custom/editor-shell/EditorShell.vue | 11 +- docs/tranches/B/FINAL.md | 39 +- docs/tranches/B/waves/W6.md | 17 +- docs/tranches/C/PROGRESS.md | 39 +- scripts/capture.mjs | 528 +++++++++++++++--- scripts/lib/demo-driver.mjs | 268 +++++++++ scripts/lighthouse-gate.mjs | 311 +++++++++++ scripts/occlusion-gate.mjs | 410 ++++++++------ 11 files changed, 1873 insertions(+), 313 deletions(-) create mode 100644 bench/loaf-scene.html create mode 100644 scripts/lib/demo-driver.mjs create mode 100644 scripts/lighthouse-gate.mjs diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 5fe0cd8..8ed657b 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -11,10 +11,18 @@ # proof:boundary — bundle EVERY light barrel entry and assert 0 value.js + # 0 static engine edge per entry, the heavy engine dynamic-only, # no dormant static specifier (A inv α, widened in B.W2) -# `@mkbabb/glass-ui` is an OPTIONAL `file:../glass-ui` dependency; a clean -# runner has no sibling checkout, so `npm ci` cleanly SKIPS it -# (`optional: true`) — verified by the /tmp clean-runner archive run.

Audit evidence is under `audit/`. ## Phase -**DEVELOPMENT** (W0 — audit + planning + the harness check-in, RUN now). The -implementation half (W1-W5) is authored-now-run-later and opens only on -explicit user authorization. No engine or demo source is written in -development. The dev/impl boundary lands at the W0 close (this board + C.md + -the W1-W5 specs + the audit evidence + the checked-in capture harness). +**IMPLEMENTATION** (W1-W5 — AUTHORIZED, running on branch `tranche-c-impl`). +W0 (audit + planning + harness check-in) is closed on master; the user +authorized the implementation half in totality.
