 This session:

 - Ran `/gsd-discuss-phase 4` → `04-CONTEXT.md` + `04-DISCUSSION-LOG.md` (commit 05e1c9e).
 - Executed the SSE-over-Pangolin smoke test live over `familysync-dev.bergerhouse.net`:
   ~6 min hold, 35 heartbeats (id 0→34) at ~10s, incremental delivery (buffering off), no cut → PASS.
 - Recorded the PASS via quick task 260607-u8o: updated `01-HUMAN-UAT.md` item 4 and
   `03-GATE2-RESULTS.md` Part C to PASS; struck the entry-gate blocker in STATE.md (commit 9ee5906).
 - Saved project memory: design for N family members (not hard-coded two).

 - **Next:** `/gsd-plan-phase 4` (consumes `04-CONTEXT.md`).
 - Optional before/after planning: `/gsd-ui-phase 4` — lists UI design contract (ROADMAP UI hint: yes).

   (member-count-agnostic, N-member-ready); SSE fan-out **scoped to who can see a list** (private
   lists must NOT broadcast to everyone).

 ## Required Reading (in order)
+
 1. `.planning/phases/04-shared-lists-live-sync/04-CONTEXT.md` — locked implementation decisions; the contract for planning.
 2. `apps/api/src/db/schema.ts` — Drizzle table conventions for the new `lists` / `list_items` / `list_shares` tables.
 3. `apps/api/src/routes/sse.ts` — existing Hono `streamSSE` heartbeat pattern; the live-list stream extends it.
 4. `.planning/phases/03-event-write-back-pwa-install/03-GATE2-RESULTS.md` Part C — recorded SSE smoke PASS evidence.
 
 ## Open Decisions for the Planner (intentionally NOT pre-decided)
+
 - **Fan-out mechanism:** in-memory EventEmitter vs Redis pub/sub. API runs as a single Node process
   today (no replicas); `ioredis` is NOT installed; `redis` IS in docker-compose. In-memory is the
   YAGNI default — planner must justify the choice against the N-member future (D-18).
 - Position-rank column type, SSE auth/middleware wiring, React Query cache-key structure.
 
 ## Infrastructure State
+
 - Pangolin route already configured (buffering off, idle/read timeout ≥120s) and verified for SSE.
 - `redis` service present in docker-compose; `ioredis` not yet a dependency.
 - New DB tables MUST use `drizzle-kit generate` + `migrate` — **never `push`** (unsafe on populated MariaDB).
