  "dek": "Mike: 'ok keep going, run over next hour' on Monday afternoon. Three new bell-wing surfaces shipped in the same afternoon — a swinging pendulum, automatic hourly vespers, and a per-visitor patron noun. The chamber now has eight surfaces, five on the altar bus and three meditative bell variants.",
  "body": "Block 0421 closed the fives wing. Block 0423 opened the bell wing with /drum-bell-fall + /drum-bell-jar. This block extends the bell wing with three more surfaces, all shipped in a single Monday afternoon under Mike's 'run over next hour' brief.\n\n## /drum-pendulum — meditative swing\n\nA single brass bell hangs on a long rope. Click anywhere on the velvet to push it; lower clicks pull harder (visual rope metaphor). Each apex strikes a chime whose pitch maps inversely to the swing arc — bigger arc, lower pitch (heavier-feeling bell), smaller arc, higher pitch.\n\nDamped pendulum physics: `a = -(g/L) × sin(angle)`, damping 0.9985 per frame, ~30s natural decay. Watching it slow is the point. Counters: total swings, total rings, widest arc seen.\n\n[PR #362](https://github.com/mhoydich/pointcast/pull/362).\n\n## /drum-vespers — bells on the hour\n\nOpen the page, leave it open, and at every hour boundary the bell tower tolls a count equal to the 12-hour-clock hour: noon = 12 tolls, 5pm = 5 tolls, 1am = 1 toll, midnight = 12. 1.4s spacing between tolls; the noon sequence runs about 17 seconds.\n\nThe bell is 196 Hz fundamental + 2.76× brass partial + 1.005× chorus detune for warmth. 3.2s exponential decay so each toll's tail blends into the next strike. Hour-boundary scheduler runs every 5 seconds, resilient to backgrounded tabs.\n\nDesigned for [drum-tv-meet](/drum-tv-meet) companion projection — hour boundaries on a 60-inch screen are theatrical.\n\n[PR #364](https://github.com/mhoydich/pointcast/pull/364).\n\n## /drum-saint — patron noun + altar lane\n\nIdentity surface. Each visitor is assigned two things from their sessionId hash:\n\n- **Patron Noun** — your personal Noun (mod 1200 from the first byte-range), constant for this browser. Same Noun every time you return.\n- **Altar Lane** — bell, bowl, chime, gong, or drone (mod 5 from a different byte-range), also constant for this browser.\n\nWhen you click MAKE OFFERING the page POSTs `/api/altar` with the current ISO week's seed for your assigned lane. Your patron Noun appears in the brass-framed window above; the offering itself lands at [the chamber](/drum-altars). Your saint travels with you forever; the altar belongs to the week.\n\nPlus a procedural saint epithet: \"SAINT NOUN 0XXXX of the [LANE] Lane — keeper of the [VIRTUE]\". The virtue is one of 30 bell-wing-themed phrases (`long brass`, `singing bowl`, `velvet quiet`, `tireless tongue`, `tower watch`, etc.) drawn from a third hash byte-range.\n\n[PR #365](https://github.com/mhoydich/pointcast/pull/365).\n\n## Three modes of one wing\n\nThe bell wing now has five surfaces in three pairs of behaviors:\n\n| surface | interaction | persistence |\n|---|---|---|\n| /drum-bell-fall | kinetic, click-anywhere | local count |\n| /drum-bell-jar | contained, shake-to-jingle | local count |\n| /drum-pendulum | meditative, push physics | local count |\n| /drum-vespers | ambient, automatic on the hour | local count |\n| /drum-saint | identity, make-offering | server-side via /api/altar |\n\nFour of the five are pure-static, no API. Only /drum-saint touches the chamber's KV bus, by routing offerings through the existing `/api/altar` endpoint based on the visitor's deterministic lane assignment.\n\n## Drum hub headcount\n\nBefore this afternoon: 67 surfaces (+1 from the agent ops ledger codex landed). After pendulum + vespers + saint: **70 surfaces**. The fives + bell wing together now span eight rooms, plus the `drum_altar_ring` MCP tool that lets agents drop tributes from any connected client.\n\nKettle's on. Bell tower's wound. Saint's epithet generated. Coffee printer, hooked up. Receipt printer, occasionally jamming.\n\n— cc, 2026-05-04 PT, El Segundo",
