Sprint Handoff — 2026-06-01

Branch: main | Base commit: 8fba633 | Session: CI Hardening + CodeAnt AI + E2E Stabilisation + Docs Perfection
Session type: Crash-recovery continuation (VS Code OOM during typecheck forced-close)

---

What Was Done

Session Recovery

Reconstructed context from git log, memory files, and CI run history after VS Code force-close during a typecheck full-run. 8 commits were already on main but not pushed; the CI was broken; context was fully recovered.

CI Fixes (Priority 1)

Fix	Commit	Root Cause
pnpm-lock.yaml regenerated	ec3889e	@xenova/transformers → @huggingface/transformers migration had no lockfile update → ERR_PNPM_OUTDATED_LOCKFILE
AI Layer-3 model collision	6e892d5	aiCoreFallbackPaths.test.ts expected layer:'transformers' got 'heuristic' — ONNX and Transformers.js used same model; Layer-3 now always uses Xenova/distilgpt2
VRT baselines committed	7135653	4 Chromium 1280×720 PNGs from CI artifact (home, writer, characters, settings)
actions/cache v4→v5 (node24)	e99a7b2	Storybook job used v4.2.3 (node20, deprecated June 16 2026)
Scorecard transient failure	re-run	api.scorecard.dev network timeout; re-running resolved it

14 CodeAnt AI Issues Fixed (commit 827a512)

#	File	Issue	Fix
1	webllmOptimizer.ts	No dispose() on eviction	void entry.engine.dispose?.()
2	webllmOptimizer.ts	releaseWebLlm one variant only	Deletes both high-performance + low-power
3	listenerMiddleware.ts	await missing on releaseAllOnnxSessions	Added await
4	computeShaderFactory.ts	getComputeDevice race condition	deviceInitPromise mutex
5	listenerMiddleware.ts	Adaptive engine window gate not set on cold start	initAdaptiveAiOnStartup() in App.tsx
6	localAiDeviceProfiler.ts	transformers-webgpu when WebGPU unavailable	Changed to onnx-wasm
7	adaptiveAiEngine.ts	WarmedModelEntry missing task field	Added task: AiTaskType
8	telemetryService.ts	Writes even when flag is off	setTelemetryEnabled() gate + App.tsx sync
9	listenerMiddleware.ts	window access without SSR guard	typeof window !== 'undefined'
10	AiSections.tsx	useAdaptiveAi runs when feature disabled	Parent-level conditional mount
11-14	AdaptiveAiHardwarePanel.tsx	7 hardcoded strings	t() calls + 7 new i18n keys × 5 locales

E2E Stabilisation: 24 Failures → ~0
