* feat(sse): per-client live subscription filter
Lets a connected client narrow its SSE stream to a single session
without forcing an EventSource reconnect. With many open sessions
(N tabs in the UI, all generating output), this cuts terminal-event
SSE traffic by roughly Nx — we only send the actively-rendered
session's bytes instead of all of them.
The existing ?sessions= query filter only worked at connect time;
narrowing or widening it required tearing down the EventSource and
losing in-flight messages. That was acceptable when filters were set
once at page load, but the UI now flips active sessions on every
tab switch.
How it works
============
- Client generates a stable per-page UUID (`_clientId`) once at
CodemanApp construction and includes it on the SSE URL:
GET /api/events?clientId=<uuid>&sessions=<active-id>
- Server records a `clientId -> reply` mapping in addition to the
existing `reply -> sessionFilter` map.
- New endpoint:
POST /api/events/subscribe { clientId, sessions: string[] | null }
updates the in-memory filter for the matching reply. 204 on success,
404 if the client isn't known yet (race on first selectSession after
reconnect — the next reconnect carries the filter via the URL).
- On every selectSession the client fires a fire-and-forget POST. No
reconnect, no re-init, no replay buffer needed.
Behavioural change to broadcast()
=================================
The per-event session filter is removed from `broadcast()`. Previously
that path filtered lifecycle/metadata events (`session:created`,
`session:updated`, `ralph:*`, `hook:*`) by extracting a `sessionId` from
the payload. With per-client narrow filters, that meant a client
subscribed to session A would never see session:created for B and the
sidebar would silently de-sync.
The new contract:
- **Lifecycle/metadata events** (low-volume, UI-correctness critical)
broadcast to all clients regardless of filter.
- **Terminal events** (high-volume, the actual reason for filtering)
apply the filter in `flushSessionTerminalBatch` (already there;
unchanged).
`extractSessionId()` was only used by the old broadcast() filter and
has been removed.
Files
=====
- src/web/sse-stream-manager.ts (+34/-29): add `sseClientsById`,
optional `clientId` arg to addClient/removeClient cleanup, new
`updateClientFilter()`, and the broadcast() change above.
- src/web/server.ts (+22/-3): parse `clientId` on /api/events, pass
to `addClient`, register POST /api/events/subscribe handler.
- src/web/public/app.js (+41/-1): generate `_clientId`, build the
EventSource URL with both clientId + active session, add
`_updateSseSubscription()`, call it on selectSession.

* test(sse): update operation-lightspeed to match broadcast-all contract
Lifecycle events (session:*, case:*) now reach every connected SSE
client; only session:terminal is gated by the per-client filter.
Updates the four assertions in operation-lightspeed.test.ts that
encoded the old "filter applies to all events" contract.

Knip-driven cleanup. All changes verified with tsc --noEmit, lint, and
build.
Removed (zero consumers):
- VERIFICATION_PROMPT constant + its barrel re-export
- createInitialOrchestratorPersistState factory
- transcriptWatcher singleton export
- createAnsiPatternFull / createAnsiPatternSimple factories
- TimerInfo interface + unused AiCheckResult/AiPlanCheckResult imports
in respawn-controller.ts
- 35 unused Zod z.infer \`*Input\` types in schemas.ts
- Dead re-exports: SessionMode from session.ts, AuthSessionRecord from
web/ports/index.ts, EnhancedPlanTask/CheckpointReview from
ralph-tracker.ts, 7 unused entries in utils/index.ts
- 14 event/config interfaces that lived only as JSDoc hints (no TS type
position usage): Session/Respawn/RalphLoop/RalphTracker/
SessionManager/SessionAutoOps/Subagent/TaskQueue/TaskTracker/
TranscriptWatcher/Image/OrchestratorLoop Events + RespawnPreset +
SessionOutput
Narrowed to module scope (kept but no longer exported):
- buildPermissionArgs in session-cli-builder.ts
- 28 type/interface declarations used only within their own file:
Ai{Idle,Plan}Check{Config,State}, BashToolParser{Events,Config},
FileStream/CreateStream{Options,Result}, PlanSubagentEvent,
SubagentCallback, RalphLoopConfig, RalphLoop{Events,Options},
ActiveTimerInfo, DetectionStatus, ActionLogEntry, AutoOpsCallbacks,
TunnelStatus, Timer/LRUMap/StaleExpirationMap Options, AuthState,
SessionListenerDeps, SseStreamManagerDeps, and 8 more
Docs: CLAUDE.md advice for global-regex `lastIndex` now points to the
remaining `execPattern()` helper instead of the deleted factories.
Knip delta: unused files 42→0, unused exports 161→16, unused types 92→0.
The 16 remaining exports are a mobile-test helper toolkit intentionally
kept for upcoming tests.
