New tooling in tests/tools/screenshots/ (TypeScript via tsx):
- compare.ts: one pixelmatch engine (AA-excluded), connected-component
"where to look" boxes, old|new+boxes|heatmap triptych, per-engine floors.
- promote.ts: churn-free updater — overwrite a baseline only when decoded
pixels differ beyond the floor, copying CI bytes verbatim (no re-encode
churn); pulls a CI run via `gh run download` or a local --from dir.
- post-discord.ts: always-on CI-on-main report (SHA + e2e status + the
track-only runtime-perf table), then screenshot triptychs, batched +
size-capped + flood-collapsed + 429-aware.
- perf-report.ts: perf table with Δ vs the previous main run (via gh).
- changelog.ts: no-build git-history baseline differ (Discord trigger B).
- noise.ts / gen-manifest.ts: calibration + manifest generation.
CI wiring:
- wasm-build.yml: post-test step runs the gate + report on the already-
produced test-results (no extra build); report-only (continue-on-error),
posts only on push to main, inert without DISCORD_WEBHOOK_URL.
- ci-ubicloud.yml: secrets: inherit (pass the webhook through).
- screenshot-changelog.yml: ~30s no-build changelog on baseline changes.
screenshot-manifest.json: canonical 354-name set + best-effort engine tags
(313 chromium-swiftshader / 41 firefox-llvmpipe).
Normalize scale:'device'->'css' across 18 spec files (no-op at CI DSF=1)
so committed baselines are uniformly css-scaled.
Design: CI's Linux render is the single source of truth; no pinned
container (accept rare env drift -> re-promote); dev commits via promote.
Replaces the byte-cmp compare-screenshots.sh + file-size-proxy
update-baseline-screenshots.sh (kept for now until the first re-baseline).

The emscripten fiber glue gates Fibers.trampoline() on Fibers.trampolineRunning
and resets it at the end of its loop. At startup emscripten_set_main_loop(...,1)
throws "unwind" to establish the main loop, and KiCad does so from inside a tool
coroutine, so the throw propagates THROUGH the trampoline and skips the reset —
leaving the flag stuck true. Every fiber swap after startup then becomes a silent
no-op, so opening a schematic (SetScreen -> RunAction(selectionClear) -> fiber
swap) hangs forever with the editor stuck on "untitled".
Wrap the trampoline loop in try/finally (inject-dyncall-shims.sh section "3c") so
the flag is always reset. Add tests/kicad/eeschema-load.spec.ts, which opens a
small wires/junctions schematic via Module.kicadOpenFile and asserts the editor
title switches away from "untitled": it times out (RED) without the shim and
passes (GREEN) with it. Also add features/web-init/0002-url-regex-modal-followup.md
capturing the unrelated URL-detection wxRegEx modal surfaced once loading works.
