-# Meeting Prep — "Next up" prep card
-
-## Goal
-
-When a meeting is imminent, surface who will be there by pulling up each
-attendee's existing `person.md` from the knowledge base and showing it — no
-click, no LLM in the hot path. An ambient card that's just *ready* when you
-look.
-
-This is a deliberately light, deterministic surface. It does **not** replace
-the two existing meeting-prep paths:
-- the chat skill (`assistant/skills/meeting-prep/`) — LLM brief on demand
-- the pre-built automation (`pre_built/meeting-prep.md`) — LLM brief files
-
-It complements them with an instant, no-LLM "who's in this meeting" view.
-
-## Decisions (settled)
-
-| Axis | Choice |
-|------|--------|
-| Surface | **Ambient card**, no notification. Pinned at top of Meetings view. |
-| Activation | Next eligible meeting is **≤ 30 min away**. Outside that → no card. |
-| Depth | **Just show `person.md`** — render the note, no LLM synthesis. |
-| Who | **Everyone incl. teammates.** Skip self / all-day / declined / cancelled. |
-| Sparse meetings | **Notes-first**: attendees with notes shown prominently; the rest collapse into "N others — no notes yet" → expand to create. |
-| No-note action | **Offer to create** a note for that attendee. |
-
-## Resolution rules
-
-For each attendee (excluding `self`):
-1. **Email exact match** (case-insensitive) against `KnowledgeIndex.people[].email` — reliable.
-2. Else **name/alias match** on `displayName` → `people[].name` / `people[].aliases`,
-   only when it's a **single unambiguous hit**.
-3. Matched → read `person.md`, return `{ name, role, org, path, markdown }`.
-4. Unmatched → returned as a "no note" attendee (name + email).
-
-Org notes (`Organizations/{Org}.md`) are **deferred** — `person.md` already
-carries Org/Role inline, enough for v1.
-
-## Architecture
-
-| Piece | Location | Notes |
-|-------|----------|-------|
-| Attendee → note resolver | **new IPC** `meeting-prep:resolve` in `apps/main/src/ipc.ts` | Input: attendee list (`{email?, displayName?, self?}[]`). Builds/uses `buildKnowledgeIndex()`, resolves per rules above, reads matched notes, returns structured payload. Deterministic + fast. |
-| Shared types | `packages/shared/src/` | `MeetingPrepAttendee`, `MeetingPrepResult` request/response shapes + IPC channel typing. |
-| "Next up" card UI | **new component** rendered above `UpcomingEvents` in `meetings-view.tsx` | Picks next event ≤30 min out, calls IPC, renders notes-first + collapsed others. Reuses existing markdown rendering. |
-| Create-note action | reuse the note-creation agent (only LLM touch, user-initiated) | v1: open a prefilled Copilot chat to create the note (visible/steerable) rather than firing silently. |
-
-No new background loop — the renderer already polls `calendar_sync/` every
-minute, so the card stays current for free.
-
-## Build slices
-
-1. **Resolver IPC + shared types** — `meeting-prep:resolve`, wired through
-   preload. Unit-testable in isolation. ← first slice
-2. **"Next up" card UI** — component + 30-min gating + notes-first / collapsed
-   rendering, reading from the IPC.
-3. **Create-note action** — prefilled Copilot chat for an unmatched attendee.
-
-## Out of scope (fast-follow candidates)
-
-- Notification variant (extend `notify_calendar_meetings.ts` tick).
-- Org-note surfacing.
-- Configurable lead time (hardcode 30 min for v1).
-- LLM-synthesized brief button on the card.
-
-## Phase 2 — Proactive, meeting-aware prep (6h ahead)
-
-Shift from a static contact viewer to meeting-aware prep, generated ahead of time.
-
-### Decisions
-- **Trigger:** a calendar-driven tick (clone of `notify_calendar_meetings.ts`), NOT the
-  cron/bg-task engine — fire time is `start − 6h`, which varies per event, so a
-  calendar scan + state file is the right fit (self-healing on reschedule/cancel).
-- **Storage:** write a real note → `knowledge/Meetings/prep/<slug>-<date>.md` (openable/editable).
-- **Notify:** none — silent background generation; appears in the Meetings view.
-- **Adaptive by meeting type:**
-  - Recurring (`recurringEventId` + prior notes found) → lead with **"Last time" recap**
-    (prior instance's `## Action items` / summary), then roster.
-  - One-off / new → lead with **agenda** (event `description`), then roster + company.
-- **Roster:** always list every attendee; ones with a note link to it, ones without
-  get **Create note**.
-- **AI brief:** the only LLM step. Reuses the `summarizeMeeting` path exactly —
-  `generateText` against the user's configured model (`getMeetingNotesModel` /
-  `getDefaultModelAndProvider`), tagged `useCase: 'meeting_prep'`. Deterministic
-  parts (roster, recap, agenda) are assembled in code; the model only writes the
-  "what matters" summary.
-
-### Build slices
-- **A. Core generator** (`meeting_prep_brief.ts`): assemble context (roster + recap +
-  agenda, meeting-type aware) → `generatePrepBrief()` (one model call) → render +
-  `writePrepNote()` to `knowledge/Meetings/prep/`. Frontmatter stamps `eventId` /
-  `recurringEventId` / `meetingDate` / `generatedAt`.
-- **B. Scheduler** (`meeting_prep_scheduler.ts`): tick (~few min), scan `calendar_sync/`,
-  for events starting within 6h, not ended, ≥1 non-self attendee, not already prepped
-  (state file keyed by eventId) → generate + write. `init()` wired in `main.ts` beside
-  `initCalendarNotifications()`.
-- **C. Card integration:** the inline prep card prefers the generated prep note when it
-  exists (instant), else falls back to the live deterministic resolve.
-
-### Open detail / enabler
-- Notes don't store an event id today, so recap linking is a title/date heuristic.
-  Stamp `eventId`/`recurringEventId` into captured notes' frontmatter going forward so
-  future links are exact.
-
-## Verification
-
-- Resolver: feed known attendee emails → correct note match; unknown → no-note.
-- Card: appears only inside the 30-min window; notes-first ordering; collapse
-  toggles; create action opens prefilled chat.
-- `npm run deps && npm run lint` clean.
