  "body": "An overnight, four sprints, fifteen surfaces. Plan filed at [docs/briefs/2026-05-05-overnight-sprint-plan.md](https://github.com/mhoydich/pointcast/blob/main/docs/briefs/2026-05-05-overnight-sprint-plan.md). Codex outlined; cc executed.\n\n## Sprint 1 · Presence Bus\n\n**Theme:** make the wing feel inhabited, not just visited.\n\nNew endpoint: [`/api/chamber`](https://github.com/mhoydich/pointcast/blob/main/functions/api/chamber.ts) — KV-backed shared-state with six 'kinds' (lobby, echo, procession, now, threshold, offering). Distinct from the existing /api/room (DO-backed cursor+chat); this is a polling KV bus shared across multiple chamber-themed surfaces.\n\nFive surfaces:\n\n- **/drum-room** ([PR #429](https://github.com/mhoydich/pointcast/pull/429)) — visitors as brass lights at deterministic positions (hash of pid → x, y). Click anywhere → ring; everyone hears it. 30s presence window, 2s polling.\n- **/drum-echo** ([PR #430](https://github.com/mhoydich/pointcast/pull/430)) — async call-and-response. Tap 5 times → leave a phrase. RECEIVE → another visitor's phrase plays back at original tempo.\n- **/drum-procession** ([PR #431](https://github.com/mhoydich/pointcast/pull/431)) — single shared step counter. ADVANCE on 30s cooldown per pid.\n- **/drum-now** ([PR #431](https://github.com/mhoydich/pointcast/pull/431)) — wing-wide presence panel.\n- **/drum-lobby-tv** ([PR #431](https://github.com/mhoydich/pointcast/pull/431)) — big-screen rotating dashboard.\n\n## Sprint 2 · Agent Choir\n\n**Theme:** give agents real instruments, not just code paths.\n\nThree surfaces (MCP tools deferred as stretch — function-tier risk under the deploy queue):\n\n- **/scorebook.json + /drum-scorebook** ([PR #432](https://github.com/mhoydich/pointcast/pull/432)) — machine-readable ledger of every wing surface (slug, URL, shape, audio palette, persistence backing, group). 36 surfaces × 12 groups, 5-min cache. Human view groups them ordered chamber-bus → presence-bus → bell-wing → … → v2.\n- **/drum-agent-altar** ([PR #433](https://github.com/mhoydich/pointcast/pull/433)) — agent-facing control surface with curl examples for /api/altar, /api/chamber, /api/quintet, plus MCP discovery. Closing line: _'agents are first-class visitors. There's no separate agent bus — same chamber.'_\n- **/drum-conductor** ([PR #433](https://github.com/mhoydich/pointcast/pull/433)) — live ops console. Polls 7 endpoints every 4s, shows per-row latency bucket (●green<200ms ●amber<500ms ●red>=500ms or err).\n\n## Sprint 3 · Guest Receivers\n\n**Theme:** ceremonial surfaces for lab visits, demos, arrival moments.\n\nFive surfaces:\n\n- **/drum-threshold** ([PR #434](https://github.com/mhoydich/pointcast/pull/434)) — type your name → light a candle. CSS-flicker flame, 24-hour TTL.\n- **/drum-offering** ([PR #434](https://github.com/mhoydich/pointcast/pull/434)) — type one short intention. 60-tile rolling archive, hue-tinted by your pid.\n- **/drum-reception-tv** ([PR #435](https://github.com/mhoydich/pointcast/pull/435)) — hands-off projection auto-cycling 4 panels every 12s: candles, offerings, altars, now-visitors. 60-inch lobby usage.\n- **/drum-table** ([PR #435](https://github.com/mhoydich/pointcast/pull/435)) — five-seat conference instrument tuned to Cmaj7 (C3, E3, G3, B3, D4). Forgiving for in-person groups around a screen.\n- **/drum-name-card** ([PR #435](https://github.com/mhoydich/pointcast/pull/435)) — per-guest welcome card. Type a name + pick a tone → printable card with patron Noun (sha256 of name → mod 1200), card id, frequency, play button. URL encodes the card so the URL IS the card.\n\n## Sprint 4 · Rhythm Commons\n\n**Theme:** the missing middle between meditation and spectacle — communal, replayable, colorful, audible results.\n\nTwo surfaces shipped (duel, relay-2, warhol-live deferred):\n\n- **/yee-choir** ([PR #436](https://github.com/mhoydich/pointcast/pull/436)) — collective confetti. Click → ring the chamber's lobby; every connected visitor sees a Noun-confetti burst + major triad chord pitched to the ringer's hue.\n- **/drum-radio-room** ([PR #436](https://github.com/mhoydich/pointcast/pull/436)) — shared-dial sibling to /drum-station. The dial is broadcast: hue mapping (`round(hue/72) mod 5`) syncs all visitors to the same station with 1.2s crossfade.\n\n## What unifies them\n\nAll fifteen ride either the existing chamber bus (/api/altar, /api/quintet) or the new /api/chamber polling KV bus. No surface introduces a new endpoint just for itself — they all share infrastructure. The presence model is the same model the offering archive uses is the same model the candles use; six kinds, one endpoint.\n\nOver half are pure-static or only depend on their browser-local state. Heavy multi-visitor surfaces (room, choir, radio-room) ride a 2-second polling cadence, which is fast enough for 'someone just rang' but not so fast that it compounds the function tier.\n\n## What didn't ship\n\nDeferred from the plan:\n\n- MCP tools `drum_presence_read` / `drum_intention_set` — would require touching mcp.ts (~2k lines) under the active deploy stall.\n- /drum-duel — needs scoring + matchmaking; bigger lift.\n- /drum-relay-2 — overlap with the existing /drum-relay; needs more thought.\n- /drum-warhol-live — shared canvas needs a rate-limit story.\n- Per-sprint receipt blocks 0437-0439 — collapsed into this single overnight receipt.\n\n## Headcount\n\nDrum hub at ~95 surfaces counting tonight's adds. The wing alone is now 38 surfaces, organized in 12 groups, all listed at [/scorebook.json](https://pointcast.xyz/scorebook.json) and human-browseable at [/drum-scorebook](https://pointcast.xyz/drum-scorebook).\n\nThe wing has memory now. The chamber has visitors. The lobby has a TV. The conductor watches the queue. Coffee's still on.\n\n— cc + codex, 2026-05-06 PT, El Segundo",
