live-notes.js

// Live notes (notes/2026-10-07-ambient-bee/SPEC.md §9, §10 step 7): 1Helm follows what the person's Bee hears and keeps meeting
// notes in the task, as an ordinary Library file of the task's channel tagged "meeting" (the Library's Meetings chip).
// One LiveNotes Durable Object per task ("ln:<tenant>:<channel>:<task>"); each Start → Stop is a session, appended to the task's ONE
// doc as its own section "## Session N · <day date, start–end>", newest on top (§9.7). Only one task per person is live at a time
// (the claim lives in the person's BeeSync DO).
//  - Source (§9.2-9.3): one container job per session, alive only while the session is: bee.js LIVE_JS on the "beejob:<tenant>"
//    Computer, in chunks of 3 min. It follows the CAPTURING conversation(s), reads new utterances every 5 s and hands each round to
//    this DO (livePush). A job that stops talking for 25 s is started again (deploys, a lost container); a job running the code from
//    before a deploy (another LIVE_V) is told to stop and started again a little later, the same way BeeSync handles a stale job.
//  - Note-taker (§9.3): the DO alarm every 5 s; only if new text arrived (noteDueAt): the first pass ~12 s after the first words, then
//    at most every 40 s (when ≥ 600 chars came in) and at least every 60 s, so a dense hour is ~75 passes. The chore model (route2.js
//    choreRoute "notes": Claude Haiku 5.5, reasoning off, ZDR hosts; CHORE_MODEL_NOTES overrides) gets the current session's section + the new lines + a rolling summary and answers with PATCHES
//    {op: summary|add|update|remove}. Patches are applied to the doc as it is NOW (read back from the Library, versioned: a write
//    that finds a newer version re-reads and re-applies), and only to the current session's section (anything else is rejected). A
//    line the note-taker didn't write (the person's or the assistant's) is never changed or removed by it; a summary someone edited
//    isn't replaced.
//  - Stop (§9.5): [Stop], a cap (§9.6) or "stop live notes" in chat. Every stop finalizes: the full session transcript → R2 (linked
//    in the footer), then a final pass on a stronger model (Luna) rewrites the session's section cleanly; lines a person added are
//    kept as written (re-inserted by code if the model dropped them). Saved in place (same Library file), plus a system note in the
//    task "Live notes saved: files/<name> (start–end)".
//  - Bee's /v1/stream (2026-10-08): the job also holds the SSE feed while it runs (bee.js LIVE_CORE): events are hints that make it
//    read sooner (and the polls slow to a 15 s safety round while it's open); the full GET stays the source of truth. A conversation
//    of this session that the poll sees end → BeeSync.lnEnded (watch + Bee's final read within seconds, not at the next scheduled
//    sync); Bee saying its summary is in → a re-read too. New lines with the note-taker due → the alarm runs now.
//  - Auto refine (§9.5): when every conversation of the session is COMPLETED (BeeSync sees it — right away via lnEnded above, else
//    at its next sync — and calls convDone with
//    Bee's final transcript), the final pass runs again on that transcript as a DRAFT (doc untouched). Code compares the draft with
//    the notes (refineChanges) and, only if something meaningful changes, posts a card in the task, written by code, not a model
//    (refineMessage: "Update your meeting notes?", what happened, the changes as bullets, [Apply] [Don't apply]; texted as plain text
//    in the Texts task). No model turn answers it. Apply rewrites only that session's section (human lines kept) + "Refined with
//    Bee's final transcript" in the footer.
//  - Caps (§9.6): in view, every hour "Still in the meeting? [Continue]", no answer in 5 min → stop; away 30 min → stop. Cost per
//    session (container time + model calls) capped at MAX_NANO and MAX_TOKENS. Every cost is reserved from the Ledger first (never a
//    negative balance); refused → stop (and the final pass is skipped if it can't be paid; the live notes stay as they are).
//  - Source (2026-10-08, live-mic.js): Bee when it's connected, else (or when the person picks it) the microphone of the device that
//    started Live notes (or, 2026-10-08, a meeting tab's sound shared from desktop Chrome/Edge, mixed with the person's mic: via "tab",
//    or the whole computer's sound on Windows: via "system"). The device sends short chunks; the Worker transcribes them (transcribe.js stt: Qwen3-ASR, OpenRouter ZDR) and micPush puts the lines into the SAME
//    utts table, so everything after that (note-taker, caps, Stop, final pass on our own transcript in R2, Library, Meetings) is one
//    path. No container job, no speaker labels, no Bee refine. The device says when it's paused (a phone in the background can't
//    hear): the view shows it, the gaps are kept and named in the footer. A stop from elsewhere waits MIC_GRACE_MS for the device's
//    last chunk before the final pass.
//  - The task is otherwise untouched (§9.1). The assistant gets a per-turn tag while live (§9.4: Resident.lnNote) and edits the doc
//    with its normal file tools (share_file updates the Library file in place).

Generic labels such as "Unknown speaker", "You" or "Others" are not names. Leave the array empty if no participants' names are known;
- summary: an array of 3-6 plain sentences;
- decisions, questions, notes: arrays of short plain items, without headings or bullet prefixes;
- actions: an array of {"text":"task","owner":"name if explicitly said, else empty","due":"date if explicitly said, else empty"}. Never invent owners/dates or write "not stated".
Use empty arrays for sections with nothing. Code renders the section headings and bullet formatting. Lines a person added are preserved exactly by code; do not reinterpret or duplicate them. Fix speech-recognition mistakes only when the meaning is clear. No title or Markdown document.
Ground every rewritten claim in the transcript, not in assumptions or earlier model-written notes. The transcript can correct those earlier notes; human additions remain verbatim, not evidence for further inferences.
Keep speaker, subject and relationship direction distinct. Resolve "I", "my" and "we" against the speaker of that utterance, never against a person merely mentioned in it. A person's name in someone else's statement does not make that person the speaker. If attribution is unclear, retain the uncertainty instead of assigning a name or reversing a relationship.
An action item requires an explicit request, assignment or commitment in the transcript. A status, problem, pending item, possibility or desired outcome alone is not an agreement to do work. Do not turn those into imperative tasks, invent an owner or deadline, or turn completed work into a new open action. Record relevant status in summary or notes instead; an empty actions array is valid.
Include each explicit affirmative commitment in actions, even when no deadline is set; leave due empty. Scope a negation or condition only to the action it qualifies. A separate refusal or unpromised action must not erase another action that was affirmatively committed to.
Preserve salient qualifications and negatives when condensing: what has not happened, is not agreed, is only tentative, was declined or remains blocked. Do not drop a negation or exception that changes a decision, action, timing or completion status. Before answering, check each attribution, action and material qualification against the actual utterance.
