Executable plan queue (skills plan-queue / run-queue). Each file in queue/ is self-contained: exact files, anchors, code and copy-paste verification.

INDEX.md — the order and status of every plan.
queue/ active/ done/ failed/ — plan lifecycle.
patches/ — unified diffs referenced by plans (git apply plans/patches/<name>.diff). They were produced from code that passed its tests, and are meant to be applied in plan order (e.g. 016-media-cache-adopt.diff expects 009 and 010 applied). If a patch does not apply, stop and report — never hand-edit around it.
harness/ — small throwaway servers + Playwright checks that exercise the browser side of the P2P plans for real (OPFS, IndexedDB, WebSocket, WebRTC). Run the server from server/ (bun ../plans/harness/<x>-server.js), then node <x>-check.mjs from plans/harness/ (needs npm i --no-save playwright and a Chromium; the cloud image has one at /opt/pw-browsers/chromium-1194/chrome-linux/chrome, override with CHROMIUM=).

Environment notes: server tests need cd server && bun install; media / intake tests need ffmpeg + ffprobe; plan 003 needs network access to Google Fonts once; plan 007's pool test needs bin/yt-dlp (npm run setup) or skips. Stop a background server by PID (… & SRV=$! … kill $SRV) — pkill -f <name> also matches the shell running the command and kills it.
