Re-export the imported types for convenience: + +```typescript +export type { + CanUseTool, + PermissionMode, + PermissionResult, + Query, + SDKAssistantMessage, + SDKMessage, + SDKOptions, + SDKResultMessage, + SDKSystemMessage, + SDKUserMessage, +}; +``` + +Update `ClaudeQueryRuntime` references: the real SDK exports `Query` which extends `AsyncGenerator` with control methods. Replace all `ClaudeQueryRuntime` references with `Query`. + +Update `SDKStreamEventMessage` references: the real SDK calls this `SDKPartialAssistantMessage` with `type: 'stream_event'` and `event: BetaRawMessageStreamEvent`. The translator already handles `type === "stream_event"` via record access, so it just needs the import path change. + +Update `SDKUserMessage`: the real type uses `message: MessageParam` instead of our custom `message` shape. The `PromptQueue` already treats it as opaque, so this is compatible. Test mocks need to use the real shape. + +Update `PromptQueueController`: change `extends AsyncIterable` to use the imported `SDKUserMessage`. + +Update `ClaudeSessionContext.query` type from `ClaudeQueryRuntime` to `Query`. + +**Step 3: Update PromptQueue** + +The `PromptQueue` imports `SDKUserMessage` from `./types.js`. After Task 0, that re-export points to the real SDK type. The `PromptQueue` class treats `SDKUserMessage` as opaque (it doesn't access any fields), so the implementation needs no changes — only the test mocks need updating to use the real `SDKUserMessage` shape. + +**Step 4: Update event translator imports** + +The `ClaudeEventTranslator` imports `SDKMessage`, `SDKResultMessage`, `ClaudeSessionContext`, `ToolInFlight` from `./types.js`. After the re-exports, `SDKMessage` and `SDKResultMessage` point to real SDK types. The translator uses `asRecord()` for field access (defensive against type shape changes), so the implementation should still compile.

After re-exports, `Query` replaces `ClaudeQueryRuntime`. The adapter methods that access `ctx.query.interrupt()` and `ctx.query.close()` use methods present on the real `Query` interface. + +**Step 7: Update all test files** + +Test files that create mock `SDKMessage` objects need to use the real type shapes. The key difference: `SDKUserMessage.message` is now `MessageParam` (from Anthropic SDK) instead of our custom shape. For test mocks, construct objects that satisfy the real types. + +> **Audit amendment (A1):** `MessageParam` is a complex type from `@anthropic-ai/sdk` (transitive dep).

SSE connections bypass auth-wrapped fetch — will be unauthenticated + +**Severity:** Critical — SSE will fail with 401 in any auth-protected deployment +**Tasks:** 3, 13, 14 + +**Issue:** The plan's auth strategy injects a custom `authFetch` wrapper into `createOpencodeClient({ fetch: authFetch })`. For REST calls, this works — the hey-api client's `request()` method uses `opts.fetch` (client.gen.js line 56). **But for SSE, the SDK's `createSseClient()` (serverSentEvents.gen.js line 20) calls `globalThis.fetch` directly — NOT the injected custom fetch:** + +```js +// serverSentEvents.gen.js line 20 +const response = await fetch(url, { ...options, headers, signal }); +``` + +The `options` spread includes `headers` from the client config (via `beforeRequest` → `mergeHeaders`), but the plan only sets `x-opencode-directory` in config headers — NOT `Authorization`.

SDK errors silently become wrong-typed data — `unwrap()` never checks for errors + +**Severity:** Critical — API errors return garbage data instead of throwing +**Tasks:** 5, 7 + +**Issue:** The SDK defaults to `responseStyle: "fields"` and `throwOnError: false`. This means: +- **Success:** `{ data: T, request: Request, response: Response }` +- **Error:** `{ error: E, request: Request, response: Response }` (NO `data` property) + +The plan's `unwrap()` method: +```typescript +private unwrap(response: { data?: T } | T): T { + if (response && typeof response === "object" && "data" in response) { + return (response as { data: T }).data; + } + return response as T; +} +``` + +On error, `"data" in response` is **false** (runtime object has no `data` key). `unwrap()` falls through to `return response as T` — returning `{ error: "Not found", request: ..., response: ... }` typed as `Session[]`. Callers get silently wrong data. + +**Additionally:** Callers currently catch `OpenCodeApiError` with `.responseStatus` (e.g., `session-manager.ts` line 284: `err instanceof OpenCodeApiError && err.responseStatus === 400`). The SDK never throws `OpenCodeApiError`. With default settings, errors aren't thrown at all — they're returned as objects. + +**Fix:** Set `throwOnError: true` in the SDK config and add error translation in `unwrap()` or a wrapper: + +```typescript +const client = createOpencodeClient({ + baseUrl: options.baseUrl, + fetch: authFetch as any, + headers, + directory: options.directory, + throwOnError: true, // ← errors throw instead of returning { error } +}); +``` + +Then wrap SDK calls to translate errors to `OpenCodeApiError`: +```typescript +private async call(fn: () => Promise<{ data: T }>): Promise { + try { + const res = await fn(); + return res.data; + } catch (err) { + // Translate SDK errors to OpenCodeApiError for caller compatibility + throw this.translateError(err); + } +} +``` + +**Action:** Amend Plan — Task 3 must set `throwOnError: true`.

But `server.heartbeat` is NOT. The v1 audit's SSEEvent superset type lists 3 gap events (`message.part.delta`, `permission.asked`, `question.asked`) but misses `server.heartbeat`. + +Currently this works because SSEStream casts events as `{ type?: string }`, but when Task 11 replaces `OpenCodeEvent` with `SSEEvent`, the type system won't recognize heartbeat events in typed code paths. + +**Fix:** Add `ServerHeartbeatEvent` to the SSEEvent superset: +```typescript +export interface ServerHeartbeatEvent { type: "server.heartbeat"; properties?: Record } +export type SSEEvent = Event | PartDeltaEvent | PermissionAskedEvent | QuestionAskedEvent | ServerHeartbeatEvent; +``` + +**Action:** Amend Plan — Task 11 SSEEvent superset must include `server.heartbeat`. + +--- + +## Ask User (1) + +### 1.

Task 10 should specify the exact consumer changes. + +--- + +### 3. Provider response shape mismatch (Task 5) + +**Issue:** The old `OpenCodeClient.listProviders()` does significant response normalization: +- Converts `models` from `Record` to `Array` +- Extracts `defaults` from `res.default` +- Extracts `connected` from `res.connected` +- Returns `{ providers, defaults, connected }` as `ProviderListResult` + +The plan's `OpenCodeAPI.provider.list()` delegates to `sdk.config.providers()` and just `unwrap()`s.

SSE event type names differ from SDK Event union (Tasks 11-12) + +**Issue:** The plan says to replace `OpenCodeEvent` with SDK `Event` (discriminated union).

Timer not cleared on retry error path (Task 2) + +The `retryFetch` implementation doesn't `clearTimeout(timer)` when `baseFetch` throws a network error.

This matches the existing `OpenCodeClient.request()` behavior — minor resource leak, no functional impact. + +### A2. `as any` cast in sdk-factory (Task 3) + +The `fetch: authFetch as any` cast exists because the SDK's `Config.fetch` type expects `(request: Request) => ReturnType` (single-arg) while our wrapper has `(input: RequestInfo | URL, init?: RequestInit)`.

SSEStream test timing (Task 13) + +Test `makeStubApi` creates a synchronous async generator. Events may yield before the listener attaches.

The hand-rolled `OpenCodeClient` (691 lines, 42 methods) survived the orchestrator work unchanged. It still wraps every OpenCode REST call with native `fetch`, custom retry logic, Basic Auth, and message normalization. + +The `@opencode-ai/sdk` v1.3.0 (auto-generated from OpenAPI) provides typed wrappers for ~35 of those 42 endpoints, plus SSE streaming via `event.subscribe()`.

Same backoff logic, applied transparently. | +| Type adoption | SDK types everywhere | `Session`, `UserMessage`, `AssistantMessage`, `Part` (11-type union), `Event` (20+ discriminated variants) become canonical. Largest change but best type safety. | +| SSE migration | Yes, SDK `event.subscribe()` | Replace manual SSE parser. Keep reconnection/health wrapper. | +| API style | SDK namespaced | `api.session.list()`, `api.permission.reply()`.

CRITICAL: `projectionRunner.recover()` never called in production — projections DOA +**Source:** Tasks 1, 3, 4, 5 (all auditors investigating same issue) +**Category:** Implicit Assumptions / Missing Wiring +**Detail:** `ProjectionRunner.projectEvent()` has a lifecycle guard (line 215): if `_recovered` is false, it throws `PersistenceError`. `recover()` is NEVER called in production code — only in test files via `recover()` or `markRecovered()`. DualWriteHook catches the throw (line 149 try/catch), so events store but `messages` table is never populated. Our fix adds the same try/catch in RelayEventSink, which means events store but `messages` table stays empty. Session-switch reads from `messages` table → still returns empty. **Fix is DOA without addressing this.** +**Evidence:** `grep -rn "projectionRunner.*recover\|markRecovered" src/ --include="*.ts"` returns zero hits outside projection-runner.ts itself. Test files call it; production never does. +**Recommendation:** Add a new step in Task 3 (relay-stack.ts): call `config.persistence.projectionRunner.recover()` during startup, before DualWriteHook and handler-deps are created.

Its audit caught 2 critical issues (recover() and try/catch scope).

The `currentAssistantMessageId` is only set in `translateAssistantSnapshot()` which fires AFTER streaming completes. During streaming, every content block (text, tool_use, thinking) gets a different per-block UUID as messageId. Result: dozens of single-part "messages" in SQLite instead of one cohesive assistant message. + +**Fix:** Capture the assistant message ID from the `message_start` stream event at the START of streaming.

The original fix added a defensive `INSERT OR IGNORE INTO messages` to the `text.delta` handler, but not to `tool.started` or `thinking.start`. When the model's first content block is a tool call (no preamble text), the `INSERT INTO message_parts` violates the FK constraint (`message_id REFERENCES messages(id)`) and the bare `catch {}` silently swallows it. + +**Fix:** Add the same defensive `INSERT OR IGNORE INTO messages` to the `tool.started` and `thinking.start` handlers in `MessageProjector`, before the `INSERT INTO message_parts`. + +**Files:** +- `src/lib/persistence/projectors/message-projector.ts` — Add defensive INSERT to `tool.started` and `thinking.start` +- `test/unit/persistence/projectors/message-projector.test.ts` — Test tool.started and thinking.start before message.created + +**What the audit should have caught:** Missing Wiring — the plan added defensive INSERT for text.delta but not the other event types that also insert into message_parts. + +--- + +## Gap 3: User messages not persisted for Claude sessions + +**Root cause:** The Claude adapter only emits assistant-side events.

Phases 2, 3, 5 omit handlers / globals that the refactor must touch. Substantial amendment required before execution. + +--- + +## Critical — Blocks Plan Execution + +### C1. **Phase 3 / Design:** Server filters per-session events by viewer subscription today + +- **Source:** Phase 3 auditor; confirmed paths `src/lib/server/ws-handler.ts:198` (`getViewers(sessionId)`) and `src/lib/relay/event-pipeline.ts:111-123`. +- **Impact:** A client viewing session A never receives B's deltas under current server behavior. The plan's client-side routing-by-`sessionId` is a no-op for the triggering bug without a new phase broadening server fanout (A2's design premise). +- **Action — Amend Plan:** Add a new **Phase 0b** (server fanout broadening) between Phase 0 and Phase 1. Options: + - Drop `view_session`-based subscription; broadcast all per-session events to all clients of the project relay. + - Or: explicit subscribe-list protocol (client subscribes to `{currentId}` + any session with `processing=true` in the latest `session_list`). + - Preferred per design doc: project-scoped firehose. +- **Ask User:** project-scoped firehose OR subscribe-list? (Already presented during brainstorming — user chose A2 which implied firehose. Re-confirm with explicit phase in plan.) + +### C2. **Phase 1:** `Object.freeze($state(...))` throws at module load + +- **Source:** Phase 1 auditor; Svelte 5 `$state` proxy's `defineProperty` trap rejects `writable: false`. +- **Impact:** Task 1.2's `EMPTY_STATE = Object.freeze(createEmptySessionChatState())` crashes at import time. Entire frontend fails to boot. +- **Action — Amend Plan:** `EMPTY_STATE` must be a plain frozen object (no `$state`), OR a non-frozen sentinel enforced by convention + a test. Plan should pick one. +- **Ask User:** Plain frozen POJO (no reactivity — fine since it's a constant) vs. a live-but-unmutated `$state` with test-enforced immutability? + +### C3. **Phase 0:** Emission sites massively undercounted + +- **Source:** Phase 0 auditor; plan names 3 files, grep shows 14+ files / 40+ sites (event-translator.ts, message-poller.ts, monitoring-wiring.ts, effect-executor.ts, errors.ts, handlers/*, client-init.ts, sse-wiring.ts). +- **Impact:** Task 0.3–0.6 as written leave the majority of emission sites unchanged; TypeScript will flag hundreds of errors when Task 0.2 adds `sessionId: string` to event variants. +- **Action — Amend Plan:** Replace Task 0.3–0.6's "grep and thread" instruction with an explicit per-file task list derived from the audit. Enumerate the 14 files. + +### C4. **Phase 0:** `RelayError.toMessage()` is called from 7+ sites and constructs `type: "error"` without sessionId + +- **Source:** Phase 0 auditor; callers: `prompt.ts`, `client-init.ts`, `handler-deps-wiring.ts`, and others. +- **Impact:** After Task 0.2 makes `error.sessionId: string` required, every `toMessage()` call breaks compilation. +- **Action — Amend Plan:** Add an explicit task threading `sessionId` into `RelayError.toMessage(sessionId?)`. Decide how to handle system-level errors that have no session context. +- **Ask User:** For system-level errors (PARSE_ERROR, UNKNOWN_MESSAGE_TYPE, RATE_LIMITED, INSTANCE_ERROR, INIT_FAILED): (a) keep `error` variant and permit `sessionId: string | null`, (b) introduce a new `system_error` variant without `sessionId`, or (c) always tag with a sentinel sessionId like `"__system__"`. **(b)** is cleanest type-theoretically but needs a frontend handler. + +### C5. **Phase 2:** Missing handlers — several module-level globals and dispatch-level mutators not in the flip list + +- **Source:** Phase 2 + Phase 3 auditors. +- Omissions: + - `advanceTurnIfNewMessage` — called from dispatch level, mutates `phase`, `turnEpoch`, the `seenMessageIds` / `doneMessageIds` module sets. Must be per-session. + - `handleToolContentResponse` — `ws-dispatch.ts:825`, writes directly to `chatState.messages`. + - `replayBatch` / `replayBuffers` / `eventsHasMoreSessions` — module-level caches used by `getMessages`/`setMessages`. + - `ensureSentDuringEpochOnLastUnrespondedUser` — called from `handleStatus`. + - `registerClearMessagesHook` + module `replayGeneration` counter. +- **Impact:** After Tasks 2.12, 2.13 "delete globals" step, these functions still reference dead globals → build breaks, or silently writes to the wrong place. +- **Action — Amend Plan:** Expand Task 2.11 / 2.12 and add explicit tasks for each listed function. + +### C6. **Phase 5:** `_scrollRequestPending` cannot remain a global after Phase 3 + +- **Source:** Phase 5 auditor. +- **Plan error:** Task 5.4 says "keep scroll-request global — it's a pure UI affordance tied to the visible chat area." But after Phase 3 routes events per session, `handleError` for background session B would set the flag, and the next content-change on the visible session A wrongly consumes it. +- **Action — Amend Plan:** Move `_scrollRequestPending` into `SessionChatState`. `consumeScrollRequest()` reads from `currentChat()`. + +### C7. **Phase 3:** Deleting live-event buffering regresses a data-loss hazard + +- **Source:** Phase 3 auditor. +- **Impact:** The `liveEventBuffer` exists because a live delta arriving during an async replay of the same session currently goes into the buffer and is drained after replay commits via `commitReplayFinal`. Removing it without replacement causes the live event to bypass `replayBatch` and append ahead of the cached tail in `state.messages`. +- **Action — Amend Plan:** Either (a) preserve per-session buffering (move `liveEventBuffer` into `SessionChatState`), or (b) redesign replay to commit events one at a time so there's no batch to interleave with. Choose before Phase 3. +- **Ask User:** Option (a) — preserve buffering, per-session — or (b) redesign replay? + +### C8. **Phase 2/5:** Contradictory `_pendingHistoryQueuedFallback` / `_scrollRequestPending` treatment across tasks + +- **Source:** Phase 2 + Phase 5 auditors. +- Task 2.10 says `requestScrollOnNextContent` becomes per-session; Task 5.4 says keep it global. Same split appears for `_pendingHistoryQueuedFallback`. WeakSet vs per-state field was noted as ambiguous. +- **Action — Amend Plan:** Pick one strategy, stated consistently in both phases. Recommend per-state boolean fields on `SessionChatState` for both. + +--- + +## High — Actionable Before Execution + +### H1. **Phase 2:** `state.messages = [...state.messages, x]` bypasses `replayBatch` + +- **Source:** Phase 2 auditor. +- `getMessages()` / `setMessages()` today route through `replayBatch` during replay. Phase 2's snippet replaces `setMessages(...)` with direct `state.messages = [...]`, silently breaking replay batching. +- **Action — Amend Plan:** Keep `getMessages(state)` / `setMessages(state, msgs)` helpers (taking state).

Delete the buffering code entirely." +- Line 138 (migration step 5): "Remove ... buffering code" + +But the companion plan-of-record (`2026-04-19-session-chat-state-per-session-plan.md` Task 3.3, lines 1034-1064) **preserves** buffering by moving `liveEventBuffer` onto `SessionChatState`. Deleting the buffer as step 5 claims would reintroduce the cache-tail-then-live ordering bug (live `thinking_stop` mid-replay finalizing the thinking message, dropping cached `thinking_deltas`). + +**Fix:** Design doc must be corrected — live-event buffering is **retained per-session** on `SessionChatState.liveEventBuffer`, not deleted. Update lines 100 and 138. + +### Theme D — Firehose claim is false until Phase 0b lands (Task 4) + +Design doc line 73: "Subscription is project-scoped firehose — the existing per-project relay stack at `/p/` already delivers all project activity." + +**Ground truth:** `src/lib/relay/event-pipeline.ts:111-123,147,166` routes via `wsHandler.sendToSession(sessionId, msg)`, which iterates `registry.getViewers(sessionId)` (ws-handler.ts:197-206). Only clients that called `view_session` receive the event. Cross-session events are dropped today. + +**Fix:** Design doc must reference **Phase 0b (server fanout broadening)** as an explicit prerequisite. Migration step 4 must declare it as a dependency. + +### Theme E — SvelteMap does not deep-track stored `$state` values (Task 2) + +Design doc line 43: "Each entry is a `$state` object so inner-field mutations propagate via Svelte 5 reactivity without requiring map re-lookup." + +**Ground truth:** Svelte 5 docs explicitly say "values in a reactive map are _not_ made deeply reactive." Any `$derived` that reads via `sessionChatStates.get(id)` re-runs only when the key changes or `set`/`delete` fires — NOT when inner fields of a stored value mutate. + +Field-level reactivity DOES work **only if** a consumer holds a direct reference to the stored `$state` proxy and reads its fields; `$derived(currentChat().phase)` works because `currentChat()` returns the stable proxy reference until `currentId` changes and `.phase` read passes through the proxy's get-trap. + +**Fix:** Design doc must (a) correct the claim, (b) specify the access pattern (read through `currentChat().X`, not iterate `entries()` expecting deep reactivity), (c) mandate a test in Task 2 that asserts this invariant before Task 3 lands. + +### Theme F — "Frozen `$state`" sentinel is contradictory (Task 2) + +Design doc line 69: "`EMPTY_STATE` is a frozen `$state` ..." No `$state.frozen` primitive exists in Svelte 5. `Object.freeze` on a `$state` Proxy either throws on writes via the proxy or silently allows writes. + +**Fix:** Replace with a plain frozen POJO typed as `SessionChatState` (or drop the sentinel and return `SessionChatState | null` — see Ask User #3 below). + +### Theme G — Empty-string `sessionId`/`currentId` collision (Tasks 2, 4) + +Design doc line 49: `sessionChatStates.get(sessionState.currentId ?? "") ?? EMPTY_STATE`. Pairs with Task 4's `getOrCreateSessionState(event.sessionId)`. The empty string `""` is a valid key; if any code path writes to `""` (ghost event, dev-mode-off path, test setup, broken server message), `currentChat()` silently returns that bogus slot instead of the sentinel. + +**Fix:** Branch explicitly on null; assert `id !== ""` in `getOrCreateSessionState`. + +### Theme H — F2 (streaming-idle clear) contradicts existing defensive code (Task 3) + +Design doc §Reconciled fixes F2 (line 106): "clearing any non-idle phase when the server signals idle for that session." + +**Ground truth:** `chat.svelte.ts:781-792` explicitly preserves `streaming` on idle: "Don't clear `streaming` — that phase is data-driven (delta events are actively arriving) and should only be cleared by a done/error." Applying F2 naively (per plan-of-record Task 2.7) clears streaming unconditionally — could cut a live stream short when a stale/misrouted `status:idle` arrives. + +**Worse during Task 3 specifically:** while the adapter still routes everything to `currentChat()`, a `status:idle` event for session B arriving while currentId=A would clear A's streaming — a **new transient bug** introduced in the Task 3 commit. + +**Fix:** Either (a) adopt F2 only AFTER Task 4 routes by `event.sessionId` (move F2 fix to Task 4's commit), or (b) implement F2 differently (clear streaming only when no delta has arrived within N ms). + +### Theme I — F3 fix is under-specified (Task 1) + +Plan says: "checking both `statusPoller.isProcessing(sessionId)` and `overrides.hasActiveProcessingTimeout(sessionId)`." + +**Ground truth:** `patchMissingDone` at `src/lib/session/session-switch.ts:160-164` accepts only `statusPoller`. Making the fix needs: (a) third parameter `overrides`; (b) update call site at line 314 to pass `deps.overrides`; (c) widen guard to disjunction; (d) the inline `{ type: "done" }` at line 172 and the `{ type: "status" }` sends at 337-340 also need `sessionId` under the new contract. `SessionSwitchDeps.overrides` already declares `hasActiveProcessingTimeout` at line 71-73, so no interface change needed. + +**Fix:** Task 1 must enumerate (a)-(d) explicitly. + +### Theme J — `uiState.contextPercent` cross-store migration is undocumented (Tasks 3, 5, 6) + +`contextPercent` today lives in `ui.svelte.ts` (separate store). Its writer is `updateContextPercent` (`ui.svelte.ts:314-316`), called from `chat.svelte.ts:680`, `ws-dispatch.ts:103,436`, `session.svelte.ts:16,354`. Readers: `InputArea.svelte:107,465`, `InfoPanels.svelte:28-38,217-224`, `InputArea.stories.ts:40,60,66,72`. + +Migration step 5 says "Remove `uiState.contextPercent`" — but Tasks 3 and 6 don't document the dual-write or the component read migration. + +**Fix:** Specify a dual-write strategy for Task 3 (write both `state.contextPercent` AND `uiState.contextPercent` until module field removed); enumerate all reader/writer sites in Task 5 and 6. + +### Theme K — `historyState` pagination fields need to migrate (Tasks 5, 6) + +`stashSessionMessages` (`chat.svelte.ts:1051-1068`) preserves `historyState.hasMore` and `historyState.messageCount`. Design's `SessionChatState` (lines 31-32) lists `historyHasMore` and `historyMessageCount` but the migration tasks don't state how `historyState` (read/written in `HistoryLoader.svelte:35-92`, `MessageList.svelte:225,233`) is migrated or kept. + +**Fix:** Clarify — is `historyState` per-session or global? If per-session, HistoryLoader migrates too; if global, the pagination fields are duplicated and one source must win. (See Ask User #6.) + +### Theme L — Ghost slots for deleted sessions + all-slots-non-idle (Tasks 4, 5) + +Two related gaps: +1. `getOrCreateSessionState(event.sessionId)` will allocate a slot for any sessionId the server references, including a session the client just deleted. Eviction rule "never evict non-idle" keeps the ghost pulsing forever. +2. If the user has >20 sessions all non-idle, the LRU cannot evict anything and the map grows unbounded. + +**Fix:** (a) Add a `clearSessionChatState(sessionId)` hook wired to `session_deleted` / `handleSessionList` drop path. (b) Decide the all-non-idle policy (see Ask User #4). + +### Theme M — Mid-replay session-switch race (Task 3) + +Today, `replayBatch` is module-scoped (`chat.svelte.ts:297`), so mid-replay session switches don't cross-contaminate the buffer. If `replayBatch` moves to `SessionChatState` (per plan-of-record Task 3.2) and handlers route through `currentChat()`, a rapid switch during replay makes handlers write into the **new** session's slot mid-stream. + +**Fix:** Specify that during replay, handlers receive the `state` for the session being replayed (captured at `replayEvents` start), NOT `currentChat()`. Use a `forState(state, ...)` variant for replay paths. + +### Theme N — Emitter-side sessionId injection is under-specified (Task 1) + +Translator functions in `event-translator.ts:101-468` are pure and don't take `sessionId`. `relay-event-sink.ts:228-375` has `deps.sessionId` in scope but `translateCanonicalEvent` is a free function. `message-poller.ts:318,600` and `handlers/prompt.ts:73` each have their own emission path. The plan doesn't say where sessionId is injected (per translator, post-translation, in `push()` wrapper?). + +**Fix:** Choose and spell out a single injection strategy (recommended: post-translation tag in callers). Also flag `event-translator.ts:446`'s `sessionId: props.sessionID ?? ""` fallback — under the new contract this will pass TypeScript but fail runtime assertions. + +### Theme O — Handler/test migration is broader than "chat.svelte.ts" (Tasks 3, 5, 6) + +- `handleToolContentResponse` lives in `ws-dispatch.ts:825-843`, not `chat.svelte.ts` — must be part of the handler flip. +- `registerClearMessagesHook` interaction with per-slot `replayGeneration` needs to be decided. +- 20+ tests import handlers directly (enumerated in Task 3 audit §8) and must migrate in the same commit or violate "each commit compiles and passes the existing test suite." +- Components missing from Task 6's migration list: `UserMessage.svelte` (4 reads + `$inspect`), `ChatLayout.svelte` (unused import), `HistoryLoader.svelte` (historyState). +- Storybook: `InputArea.stories.ts` (4 contextPercent writes + phaseTo* calls without sessionId) is not mentioned — only `MessageList.stories.ts` appears called out. + +**Fix:** Enumerate every handler, test file, component, and story that requires migration. Cross-reference plan-of-record's expanded list or inline the full list. + +--- + +## Ask User (9 items) + +Decisions required before the plan is final. + +1. **Task 1 (6.2):** Should Task 1 (server sessionId additions) land in a preceding PR or as the first commit of the main PR?

Currently bundled with Task 3, but during Task 3 the adapter still routes by `currentId` so idle events for session B can clear A's streaming — a new transient bug. +6. **Task 6 (3):** Is `historyState` (loading/hasMore/messageCount) per-session or global? Affects HistoryLoader migration. +7. **Task 6 (13):** Keep or delete the `$inspect` debug logger in `UserMessage.svelte:22-33`? +8. **Task 5 (all-non-idle):** What happens when all 20 LRU slots are non-idle? Options: grow unbounded (log warn), evict non-idle oldest (risks dropping live replay), refuse new slot (breaks switch). +9. **Task 7 (2):** Is "Net LOC should be negative" a hard merge gate or a heuristic?

"")`. | +| H — F2 contradicts defensive code | Task 3 §5, 6, 14 | F2 moved from Task 3 to Task 4 (dispatcher flip commit).

Task 3 requires test migration in the same commit (20+ files enumerated).

Either the server PR adds the variant + emission, or Task 5 relies solely on the `handleSessionList` drop path. +- **`createEmptyToolRegistry()`** (Task 1 `EMPTY_MESSAGES` definition). Only `createToolRegistry()` exists in `tool-registry.ts`. Either rename in the plan or add the new factory. + +### Theme β — `composeChatState` under-specified + +The revised plan introduces `composeChatState(activity, messages)` returning a read-only Proxy, but omits critical details: + +- **Key-routing strategy:** How does the Proxy's get-trap know which keys belong to Activity (e.g., `phase`) vs Messages (e.g., `messages`)? Must either (a) maintain a static key-set per tier, (b) check `key in activity` first then fall through to messages, or (c) enumerate both tiers' keys at module init. Ambiguity allows drift. +- **Proxy invariants:** `has`, `ownKeys`, `getOwnPropertyDescriptor` traps are not specified. Svelte's `$inspect` (in `UserMessage.svelte:22-33`) iterates its target's own keys via Svelte's internal introspection; a Proxy over `{}` with no `ownKeys` trap returns `[]`, so `$inspect` logs nothing useful. Need traps. +- **Reactivity preservation:** The outer Proxy MUST pass reads through to the inner `$state` proxies each call, not cache `activity` / `messages` references that break fine-grained subscription. Plan should spell this out. + +### Theme γ — `$state` factory wrapping described twice (double-wrap risk) + +The plan specifies two `$state` wrapping steps: +1. Plan §Access patterns (~line 133): `a = $state(createEmptySessionActivity())` inside `getOrCreateSessionActivity`. +2. Plan §Migration Task 1 (~line 311): "`createEmptySessionActivity`, `createEmptySessionMessages` factories (each returns a `$state(...)` proxy)". + +If both are applied literally, `$state($state({...}))` is double-wrapped. Svelte 5 likely no-ops the outer `$state` on an existing proxy, but the intent is ambiguous. Pick one: either the factory returns a `$state` proxy (and `getOrCreate*` passes it through), or the factory returns a POJO (and `getOrCreate*` wraps it). The audit's prior Amend for this (Loop 1 Task 2 §15) specified the factory pattern; Loop 2 found the ambiguity survived into both sections. + +### Theme δ — Dispatcher snippet has concrete errors + +The `routePerSession` pseudocode in plan §Event routing has two bugs: + +- **`advanceTurnIfNewMessage(activity, event.messageId)` called unconditionally.** Many PerSessionEvent variants have no `messageId` field: `status`, `error`, `done`, `ask_user`, `ask_user_resolved`, etc. Current dispatcher gates on `"messageId" in event` — the snippet must replicate. +- **`notification_event` classification.** Plan §"Event types that must gain `sessionId`" lists `notification_event` (already optional, promote to required). But its handler at `ws-dispatch.ts:671-710` dispatches to the notification reducer, not a chat slot. Under `routePerSession`'s switch, there's no case for it → falls through to the `never` exhaustiveness default → compile error or runtime throw. `notification_event` should be classified as `GlobalEvent` despite carrying `sessionId` (the sessionId is routing metadata for the reducer, not a chat-slot key). + +### Theme ε — F2 fix too narrow + +The plan's Task 4 F2 fix sets only `activity.phase = "idle"` when a server-idle status arrives. But when a streaming session goes idle mid-stream (the exact case F2 addresses), the following Activity fields may be dirty and need cleanup: + +- `currentMessageId` — points to an unfinished assistant message +- `currentAssistantText` (in Messages tier) — mid-delta buffer +- `thinkingStartTime` — non-zero +- `seenMessageIds` — may contain the in-flight messageId +- `liveEventBuffer` — if replay was in flight, buffered deltas orphaned + +Plan needs to specify the finalization behavior. Likely: same behavior as a synthesized `done` event for the current message, then phase → idle. + +### Theme ζ — Commit-boundary compile failures + +Task 5 deletes `uiState.contextPercent`, `updateContextPercent`, and module `historyState`. Task 6 migrates component readers. Per "each commit compiles" invariant, Task 5 breaks the build if landed before Task 6. + +**Resolution options:** +- Include component migrations in Task 5 (merge Task 5+6). +- Move field deletions from Task 5 to Task 6 (Task 5 only removes the non-component call sites + renames helpers). +- Accept a transitional commit where readers cast around the missing field (ugly). + +Similarly: `handleSessionList` (Task 5 drop-path trigger) lacks diff logic today at `session.svelte.ts:242-270` — just unconditional array overwrite. Need a snapshot/diff to detect disappeared ids. **Critical edge:** search-payload responses to the session list may have fewer entries than the unfiltered state — if diff-then-clear is naive, filtering wipes all non-matching slots. Spec must guard on `isSearchPayload` or similar. + +### Theme η — Other replay paths need per-session migration + +Task 3 migrates `replayEvents` to capture a slot at start. But `replayGeneration` / async commit patterns are used elsewhere too: + +- `convertHistoryAsync` at `ws-dispatch.ts:459-469` (cache-miss `session_switched` branch) — snapshots `gen = replayGeneration`, commits only if still equal. Must capture per-session slot. +- `ws-dispatch.ts:572-580` (history_page pagination) — same pattern. + +Both must snapshot `slot.activity.replayGeneration` and commit to the captured slot's `messages`, not `currentChat()`. + +Also missed from Task 3's migration list: **`eventsHasMoreSessions: Set`** at `chat.svelte.ts:318` — a per-session flag stored as a module global. Should move into `SessionActivity.eventsHasMore: boolean`. + +### Theme θ — `replayGeneration` vs `deferredGeneration` name ambiguity persists + +Loop 1 flagged this as Task 2 §13. The revised plan acknowledges "if `replayGeneration` is a rename of the existing `deferredGeneration`, document in the commit message; if distinct, document the new concept" (Task 1). But Task 2, Task 3, and the data-model both use `replayGeneration` as though it's canonical without stating the rename. Plus Task 3 says the dispatcher buffers while "`activity.replayGeneration` is active," but the current impl (`ws-dispatch.ts:368`) uses `liveEventBuffer !== null` as the sentinel. "Active" is ambiguous — `replayGeneration` is a monotonic abort counter, not a boolean. + +Plan must: +1. Decide rename vs new concept. +2. Specify dispatcher gating as `activity.liveEventBuffer !== null` (not `replayGeneration`). +3.

Plan says "module exports stay for the old code path; Task 5 deletes them." But module Set `.clear()` during Task 2-4 is a no-op for per-session state — if the same session is re-entered after `clearMessages`, dedup carries over prior-turn messageIds. + +`clearMessages` must additionally clear the **current session's** `activity.seenMessageIds` / `activity.doneMessageIds` (via `getOrCreateSessionActivity(sessionState.currentId)`). + +### Theme λ — `registerClearMessagesHook` signature under-specified + +Task 2 says hook body "receives the sessionId being cleared." Today at `chat.svelte.ts:292` the hook is `(fn: () => void) => void` — no arg. Changing it to `(fn: (sessionId) => void) => void` requires: +- `clearMessages()` caller (`chat.svelte.ts:1006`) passes `sessionState.currentId` — nullable. +- Hook type `string | null` or `clearMessages` guards on null before invoking hook. + +Plan should pick one. + +### Theme μ — Task 2 null-`currentId` adapter policy conflicts with Task 4's + +Task 2 says the adapter "early-returns on null currentId with a dev warning (no EMPTY_STATE writes)." +Task 4 says silent dropping is "unacceptable; the counter is monitored as a SEV." + +Two different drop policies across adjacent commits. Also: legitimate early-session-load transient events (e.g., server emits a delta before the frontend has finished `handleSessionList` and set `currentId`) would be dropped without trace in Task 2. + +### Theme ν — `EMPTY_MESSAGES.toolRegistry` closure over mutable state + +`EMPTY_MESSAGES` wraps `createToolRegistry()` / `createEmptyToolRegistry()` in `Object.freeze`. Method calls on the returned registry still close over mutable internal state — `Object.freeze` doesn't stop that. An errant handler that calls `EMPTY_MESSAGES.toolRegistry.register(tool)` mutates the sentinel's registry silently (no throw). + +Mitigation options: +- Null-out the registry methods on EMPTY_MESSAGES (`register: () => { throw new Error("..."); }`). +- Make EMPTY_MESSAGES a Proxy whose get-trap returns a throwing stub for any function field. +- Accept the risk (registry mutation is rare; tests cover). + +### Theme ξ — Test coverage gaps + +Loop 2 identified several specific test scenarios the plan doesn't enumerate: + +- **Per-handler tier-contract test:** each handler, dispatch one event, assert only declared tier fields changed. (Catches silent tier leaks.) +- **Replay-per-slot migration test:** slot captured at start persists across mid-replay `currentId` change; `activity.liveEventBuffer` buffers+drains correctly; clearMessages bumps per-session generation+buffer. +- **Concurrent-replay same-session:** two `replayEvents(X)` calls concurrently — second aborts first cleanly, no cross-pollution. +- **Task 4 test scenarios:** live-during-replay-different-session, startup-race drop/buffer, F2 finalization cleanup, `notification_event` non-routing. +- **`ghost-session-cleanup.test.ts` scope:** search-payload non-eviction, active-session teardown (EMPTY_STATE fallback), mid-replay teardown. +- **Server PR:** Phase 0b broadcast semantics test (client not viewing B still receives B's events; cross-project isolation). + +--- + +## Ask User (8 items) + +Tactical decisions; none are structural. Fixer should present these before Loop 3 amendment. + +1. **Phase 0b — `view_session` semantics after firehose:** Today `view_session` triggers delivery + history backfill. Under firehose, delivery is automatic. Does `view_session` still trigger history backfill (needed for Tier 2 hydration on re-entry)? Proposed: yes — it becomes a pure "give me this session's history" request. +2. **Phase 0b — within-session ordering guarantee:** Today `sendToSession` sends per-session in order. Under broadcast, does the server still guarantee per-session ordering (not cross-session)? Frontend relies on delta-order correctness per session. +3. **Phase 0b — rollback compat window:** If the frontend PR merges and the server PR gets rolled back, the frontend dispatcher throws on every event (missing sessionId). Do we accept this (frontend depends on server PR) or should the frontend include a transitional fallback that also reads old-shape events? +4. **Task 2 — advanceTurnIfNewMessage cross-session semantics:** Currently the function's dedup is global (seenMessageIds is module-level). Per-session is strictly better, but: is any handler or test relying on the global behavior (e.g., a messageId synthesized identically in two sessions colliding to suppress a dupe)? Assumed No unless you say otherwise. +5. **Task 3 — buffer-race-during-drain policy:** When a live event arrives during `drainLiveEventBuffer`, do we (a) null buffer first and let incoming events race the drain (current impl), or (b) hold buffer at `[]` during drain and push new events into the drain pass? (b) is safer per-session; (a) matches legacy behavior. +6. **Task 3 — concurrent `replayEvents` for same session:** Should a second call (rapid switch during replay) guard early, OR should it null the previous buffer and start fresh? Pick a behavior. +7. **Task 4 — startup race:** PerSessionEvents may arrive before `session_list` populates `sessionState`. The unknown-session guard would drop legitimate events. Options: (a) buffer events pre-session-list and replay after, (b) require server to emit session_list first (ordering guarantee), (c) drop silently (accept), (d) allocate the slot anyway and reconcile when session_list arrives. +8. **Task 4 — server-side `status` sessionId correctness test:** Should the server PR add a test that synthesized `status` events at `session-switch.ts:337-340` carry the right sessionId (not just a sessionId)? Guards F2 correctness at the emitter. + +--- + +## Accept (17 items) + +Summary of informational findings worth noting, not blocking: + +- All prior Loop 1 Accept findings persist. +- `InfoPanels.svelte` contextPercent is a different derivation (from prop), not `uiState.contextPercent` — no migration needed. +- `$inspect` reactivity with `currentChat().X` reads is sound. +- Task 6 file enumeration is complete — grep verifies no missed `.svelte` sites. +- Per-component isolation test spec is sufficient. +- Storybook migration coverage is adequate. +- Net LOC phrasing clearly resolved. +- `dispatchToCurrent` deletion confirmed in Task 4. + +--- + +## Routing decision + +**Hand back to `plan-audit-fixer` for Loop 3.** 46 Amend-Plan findings and 8 Ask-User remain; none are structural.

Replace the module-level `chatState` singleton with a two-tier per-session store (unbounded Activity + LRU-capped Messages), route every incoming event by `sessionId`, and derive all UI reads from the current session's slot. +**Approach:** Land in two PRs. A **preceding server PR** ships Phase 0b (broaden `/p/` fanout to a project-scoped firehose with per-session ordering + session_list-first guarantees) and Task 1 (add `sessionId` to every `PerSessionEvent`, widen `patchMissingDone`, plumb sessionId through `RelayError.toMessage`, add `session_deleted` relay variant, add `system_error`). Once the server PR is deployed, a **main frontend PR** lands as 7 reviewable commits. Each commit compiles and passes the existing suite. No backward-compatibility shims. + +## Triggering Bug + +When the user navigates away from a completed, inactive Claude Agent SDK session and then back to it, the input-area bounce bar and the sidebar activity dot both show the session as active even though it is not. + +Root cause is a mismatch between state semantics and state shape: the frontend's `chatState.phase` is semantically "the processing phase of the **current** session" but structurally a module-level global. The optimistic cache (`stashSessionMessages` / `restoreCachedMessages`) preserves messages + turn epoch + current message id across session switches but does **not** preserve phase, leaking whichever phase was last written into the next session's view until the server round-trip reconciles. A secondary bug — `handleStatus("idle")` only clears `processing`, not `streaming` — lets a stuck `streaming` phase survive reconciliation entirely. + +See the investigation notes below for full fragility analysis (sections **Root Cause** and **Why Not Caught**). + +## Design + +### Core data model — two tiers + +Split the store by data weight, matching how Discord / Slack / Teams handle per-channel state in clients with many rooms. + +```ts +// chat.svelte.ts + +// Tier 1 — Activity. Unbounded. Small scalars + small Sets, ≪ 1 KB per session. +// Sidebar row, bounce bar, and every "is this session live" read come from here. +// Never evicted — background subagents (hidden rows) keep accurate activity forever. +// Dedup Sets live here too so a Tier 2 eviction does not cause delta duplication +// when the session is re-entered and its message history is re-hydrated. +type SessionActivity = { + phase: ChatPhase; // idle | processing | streaming + turnEpoch: number; + currentMessageId: string | null; + replayGeneration: number; // renamed from module-level `deferredGeneration` (same semantics: monotonic abort counter for stale resolvers); moves to per-session in this refactor + doneMessageIds: SvelteSet; + seenMessageIds: SvelteSet; + liveEventBuffer: PerSessionEvent[] | null; // deltas received while Tier 2 is evicted or mid-replay; type-narrowed to per-session variants only + eventsHasMore: boolean; // per-session "more events available" flag (supersedes module-level eventsHasMoreSessions Set) + renderTimer: ReturnType | null; + thinkingStartTime: number; +}; + +// Tier 2 — Messages. LRU-capped (default 20, configurable). Holds only data +// that is safely reconstructable from the server's event log. Eviction is +// free of correctness cost: the next `view_session` replays history, and +// SessionActivity.liveEventBuffer drains any deltas received meanwhile. +type SessionMessages = { + messages: ChatMessage[]; + currentAssistantText: string; + loadLifecycle: LoadLifecycle; // empty | loading | committed | ready + contextPercent: number; + historyHasMore: boolean; + historyMessageCount: number; + historyLoading: boolean; // supersedes module-level historyState.loading + toolRegistry: ToolRegistry; +}; + +const sessionActivity = new SvelteMap(); +const sessionMessages = new SvelteMap(); // LRU-bumped on touch + +// Composite read shape for the chat view. NEVER instantiated as storage. +type SessionChatState = SessionActivity & SessionMessages; +``` + +Also add to `session.svelte.ts` (introduced in Main Task 1): + +```ts +// sessionState gains an id-keyed SvelteMap maintained alongside the existing +// rootSessions / allSessions arrays. Used by the dispatcher's unknown-session +// guard (O(1) membership check) and by clearSessionChatState's diff path. +sessionState.sessions = new SvelteMap(); +``` + +**Why split by weight.** Running many subagents (most hidden from the sidebar) pushes total session count well above 20. A single LRU-capped map forces the policy "never evict non-idle," which fails when all N slots are non-idle. The split eliminates the corner case: the bounded tier holds only re-fetchable data; the unbounded tier is cheap enough to hold forever. + +**Why dedup Sets stay in Tier 1.** After a Tier 2 eviction + re-entry, server history rehydrates `messages[]`, then `liveEventBuffer` drains. If `doneMessageIds` / `seenMessageIds` had been evicted, a live delta that arrived during the eviction window could be applied twice (once via history replay, once via drain). Keeping dedup in Tier 1 prevents this. + +**messageId collision note.** `messageId` values are generator-unique (Claude SDK emits `msg_…` UUIDs; Opencode likewise; client-synthesized ones use crypto-random IDs). Per-session dedup is therefore strictly safer than the current global Set even in the ~0-probability collision case — today's global Set would suppress session B's delta if A saw the same id; per-session Sets correctly process both. + +**Reactivity contract.** `SvelteMap.get(id)` subscribes a caller to the key's presence; it does **not** deep-track mutations on the stored value. Reactivity on inner fields works only because each stored value is a `$state`-backed proxy — template reads like `currentChat().phase` pass through the proxy's get-trap and subscribe fine-grained. Consumers that iterate `.entries()` or `.values()` expecting deep reactivity on values will silently miss updates. Task 1 lands an explicit invariant test (see Tests) asserting that `$derived(currentChat().phase)` re-runs when a handler mutates the stored proxy's `phase` field. + +### Access patterns + +```ts +// Factories return plain POJOs.

Session metadata send (fire-and-forget). + +Viewer association within the server (`switchClientToSession`) remains in place as UI-state bookkeeping — event delivery no longer depends on it, but future features (presence, analytics) may. See §Known Debt for the eventual rename/split proposal. + +Draft sync is handled by a separate message (`input_sync`), unaffected by this refactor. + +**Prerequisite — Phase 0b (preceding PR).** Today `applyPipelineResult` (`src/lib/relay/event-pipeline.ts:111-123`) routes per-session events via `wsHandler.sendToSession(sessionId, msg)`, which only delivers to clients that called `view_session` (`ws-handler.ts:197-206`). Phase 0b broadens the per-project relay at `/p/` to a **project-scoped firehose** that delivers every per-session event to every connected client for that project. + +Phase 0b invariants the server must preserve: +- **Per-session ordering preserved under broadcast.** Events for session X arrive at every client in the same order the server produced them. Cross-session ordering is not constrained (events for X and Y may interleave differently across clients). +- **`session_list` first after connection.** Before the server streams any `PerSessionEvent` on `/p/`, it emits the initial `session_list` / project-bootstrap messages. This eliminates the startup race where a client receives an event for a session it hasn't yet learned about. If the server cannot satisfy this (e.g., event fires during bootstrap), events must be queued server-side until `session_list` has been dispatched. + +Without Phase 0b, Task 4 silently drops all cross-session events or hits the unknown-session guard. + +**Rollback compat.** The frontend PR strictly depends on the server PR. If the server PR is rolled back, the frontend dispatcher will throw / increment telemetry on every per-session event (missing `sessionId`). This is accepted — the frontend PR should not ship ahead of or without the server PR. Deployment order is enforced by merging the server PR first and verifying rollout before merging the frontend PR. + +**Server changes — Task 1 (preceding PR).** Every `RelayMessage` variant that mutates per-session state carries a required `sessionId: string` field. Use the `Extract` form for type narrowing (an intersection `RelayMessage & { sessionId: string }` widens rather than narrows under structural typing): + +```ts +type PerSessionEvent = Extract; +type GlobalEvent = Exclude; +``` + +Event types that must gain `sessionId: string` (exhaustive list, derived from `src/lib/shared-types.ts:269-474` + all emission sites): + +- Already required: `permission_request`, `result`. +- Already optional (promote to required): `ask_user_resolved`, `history_page`, `provider_session_reloaded`. +- Must be added: `delta`, `thinking_start`, `thinking_delta`, `thinking_stop`, `tool_start`, `tool_executing`, `tool_result`, `tool_content`, `done`, `error`, `status`, `user_message`, `part_removed`, `message_removed`, `ask_user`, `ask_user_error`, `permission_resolved`. +- Session-keyed via a different field today — normalize to `sessionId`: `session_switched` (currently `id`), `session_forked` (currently `session.id`). `history_page` already uses `sessionId`. +- **New `session_deleted` variant** — emitted by the server when a session is removed. Carries `sessionId: string`. Wired to `clearSessionChatState` on the client. +- **New `system_error` variant** for errors that are genuinely session-less (HANDLER_ERROR, INSTANCE_ERROR paths in `handleChatError`). Session-scoped errors keep using `error` with `sessionId` via widened `RelayError.toMessage(sessionId: string)`. + +**Notification event classification.** `notification_event` carries `sessionId` but is NOT a `PerSessionEvent` in this refactor's sense — its handler dispatches to the notification reducer, not to a chat-state slot.

In prod the assertion does not throw — it increments a telemetry counter and returns. Silent dropping is unacceptable; the counter is monitored as a SEV. + +Every per-session handler takes `(activity: SessionActivity, messages: SessionMessages, event)` as explicit first arguments. No handler reads `currentChat()` or any module-level chat state — routing is structural. + +**Live-event buffering — retained, moved per-session.** The existing `liveEventBuffer` exists because live events arriving for session X during replay of X had no place to go. Under the new shape, buffering is preserved on `SessionActivity.liveEventBuffer`: + +- Dispatcher accumulates live deltas in `activity.liveEventBuffer` when the buffer is non-null (set to `[]` by the replay entry point at start; nulled post-drain).

Dedup Sets (`activity.seenMessageIds` / `activity.doneMessageIds`) are already populated by the committed replay, so duplicate deltas from the buffer are suppressed. +- During drain, newly-arriving live events do NOT race: the buffer is held at `[]` (not nulled) until drain completes, so incoming events push into the same buffer and are drained in the same pass. Only after the drain loop empties the buffer does the code null it. +- Tier 2 eviction does not drop the buffer (it lives in Tier 1). When the user re-enters an evicted session, `view_session` replays history, then the buffer drains. + +**Mid-replay session switches.** Handlers invoked during replay must write into the slot for the **session being replayed**, not `currentChat()`. The `replayEvents(sessionId, ...)` entry point resolves `const slot = getOrCreateSessionSlot(sessionId)` once and threads `slot` through every dispatch; it does NOT use `dispatchToCurrent` or `currentChat()`. This prevents rapid session switches from cross-contaminating slots mid-stream. + +The slot-capture-at-start rule means a replay 1 in flight for session X continues to apply events to X's slot even if the user has switched to Y. When the user switches back to X, they see X's accumulated state. No cross-session bleed. + +**Concurrent `replayEvents(X)` for the same session.** If a second call occurs while replay 1 is in flight, the second call returns early after bumping `activity.replayGeneration` (aborting any in-flight resolver on replay 1). Replay 1's remaining `await`-resolved commits short-circuit via the generation-mismatch check. The buffer is held across this transition — live events continue to accumulate and will be drained by whichever replay finishes last. For the rapid-switch-away-and-back scenario, replay 1 completes normally under its captured slot (slot-capture rule); the user sees the final state on re-entry. + +**Other async commit paths need the same slot-capture discipline.** `convertHistoryAsync` at `ws-dispatch.ts:459-469` (cache-miss session_switched branch) and `ws-dispatch.ts:572-580` (history_page pagination) today snapshot `gen = replayGeneration` and commit only if equal. Under the new shape both must capture the per-session slot at start and snapshot `slot.activity.replayGeneration`, committing prepend/seed/historyState writes to the captured slot's `messages` (not `currentChat()`). + +### Reconciled fixes bundled with the refactor + +Three latent bugs discovered during investigation are fixed as part of this refactor, because they would otherwise re-surface under the new shape: + +- **F2 — `handleStatus("idle")` only clears `processing`, not `streaming`.** Fixed by treating a server-`idle` signal as a full phase reset for the session, including cleanup of any mid-stream state that the server is telling us has ended. **Lands in Task 4 (dispatcher flip), NOT Task 3.** Rationale: during Task 3 the adapter still routes by `currentId`, so a `status:idle` event for session B arriving while `currentId=A` would clear A's streaming — a new transient cross-session bleed. Once Task 4 routes by `event.sessionId`, the cross-session bleed is structurally impossible and F2 becomes safe to land. + + Concrete F2 behavior (`handleStatus(activity, messages, event)` with `event.status === "idle"`): + 1. If a live in-flight message is pending (`activity.currentMessageId != null`), finalize it: append a synthetic `done` for that id via `handleDone` helper path so the message lands in `messages.messages[]` as terminal. + 2. Set `activity.phase = "idle"`. + 3. Clear `activity.currentMessageId = null`, `messages.currentAssistantText = ""`, `activity.thinkingStartTime = 0`. + 4. Drain `activity.liveEventBuffer` if non-null (treat as "server says this turn is done; flush anything we buffered"). + 5. `activity.seenMessageIds` / `activity.doneMessageIds` remain — they are cross-turn dedup, not per-turn state. + +- **F3 — `patchMissingDone` guard omits the Claude SDK timeout signal.** `patchMissingDone` at `src/lib/session/session-switch.ts:160-175` currently checks only `statusPoller?.isProcessing(sessionId)`. The fix: + 1. Widen the signature to accept `overrides: SessionSwitchDeps["overrides"]` as a third parameter. + 2. Update the single call site at `session-switch.ts:314` to pass `deps.overrides`. + 3. Widen the guard to `statusPoller?.isProcessing(sessionId) || overrides?.hasActiveProcessingTimeout(sessionId)`, matching the outgoing-status disjunction at `session-switch.ts:334-336`. + 4. Add `sessionId` to the inline synthetic `{ type: "done", code: 0 }` at `session-switch.ts:172` and to the `status` sends at `session-switch.ts:337-340`. Under the new contract these events require the field. + + `SessionSwitchDeps.overrides` at `session-switch.ts:71-73` already declares `hasActiveProcessingTimeout`, so no interface change is needed beyond the parameter list widening. + +- **Module-level Sets (`seenMessageIds`, `doneMessageIds`) accumulate across sessions.** Fixed structurally by moving them into `SessionActivity`. + +### Eviction policy + +LRU cap **20 entries on Tier 2 (Messages)**. Tier 1 (Activity) is unbounded. + +Two distinct operations, intentionally not unified: +- **`ensureLRUCap()`** — called from `getOrCreateSessionMessages` on insertion. Evicts least-recently-used Tier 2 entries if the cap is exceeded. Never touches Tier 1. Never evicts the entry for `sessionState.currentId` (active session is always MRU). +- **`clearSessionChatState(id)`** — called on `session_deleted` relay event and from `handleSessionList` when a previously-known sessionId disappears. Clears BOTH tiers. Bumps the (about-to-be-deleted) activity's `replayGeneration` to short-circuit any in-flight async resolver that captured the old reference. + +Evicted Tier 2 entries are rebuilt from the server event log on next `view_session`: +- `view_session` triggers server-side history backfill (`handleViewSession`). +- Client populates Tier 2 from the received `session_switched.events`. +- Any deltas in `activity.liveEventBuffer` (accumulated while Tier 2 was evicted) drain into `messages.messages[]` post-hydration. + +`handleSessionList` (the frontend listener for the session-list message) gains diff logic: snapshot the prior ids (keys of `sessionState.sessions`), apply the incoming list, then invoke `clearSessionChatState(id)` for any id present in the prior snapshot but absent from the incoming list. **Guard:** skip the diff if the incoming list is a filtered/search payload (today the session list message may be used to deliver search results — clearing non-matching sessions from chat state would be incorrect). The guard uses a payload flag or a separate message type; implementation detail to be confirmed against `src/lib/handlers/session.ts`. + +**No "all slots non-idle" corner case.** The original single-map design needed the rule "never evict non-idle" to avoid dropping live state. The two-tier split removes live state from the LRU — live state is in Tier 1, which is unbounded. The memory cost of Tier 1 per session is a handful of scalars + two small Sets (≪ 1 KB); scaling to hundreds of background subagents is fine. + +### View-layer changes + +- **`InputArea.svelte` bounce bar**: `{#if isProcessing()}` unchanged at the call site. `isProcessing()` internal becomes `currentChat().phase !== "idle"`. (`InputArea.svelte:229` reads `isProcessing()` inside a call to `addUserMessage`; it auto-migrates via Task 2's handler flip — no direct Task 6 change at that line, listed in the file catalog for reviewer orientation only.) +- **`SessionItem.svelte` dot**: + ```ts + const isProcessing = $derived( + session.processing || + getSessionPhase(session.id) !== "idle" + ); + ``` + OR is intentional — either signal suffices. If the LRU has dropped Tier 2 but the server says `processing`, the row still pulses. If the per-session phase has updated before the server flag, the row still pulses. No special case for `session.id === currentId`. The map read is scoped to this row's session. + Delete the `import { isProcessing as chatIsProcessing }` import (used in the OLD OR); replace with `import { getSessionPhase } from "../../stores/chat.svelte.js"`. +- **`MessageList.svelte` and all chat-area readers**: `chatState.X` → `currentChat().X`. Local `const` bindings (e.g., `const _len = chatState.messages.length`) rewrite on the RHS only: `const _len = currentChat().messages.length`. Inside `$derived(...)`, replace with the call form: `$derived(currentChat().phase)` — do NOT hoist `currentChat()` to a const outside the derived; each derived must re-call to pick up `currentId` changes. `untrack(() => isProcessing())` guards continue to work since `untrack` disables reactivity regardless of implementation. +- **`UserMessage.svelte`**: reads `chatState.turnEpoch`, `chatState.currentMessageId`, `chatState.phase` at lines 9, 19, 27, 29, 30.

The caller at `chat.svelte.ts:1006` (`onClearMessages?.()`) passes `sessionState.currentId` (may be null during teardown). Hook body in Task 2 is signature-only plumbing — no behavior change until Task 3. +- Handler signatures use narrowed message types preserved via generic: `dispatchToCurrent(fn: (activity, messages, msg: T) => void, msg: T)`. +- Wire through a temporary `dispatchToCurrent` adapter that routes to `getOrCreateSessionSlot(sessionState.currentId)`. **Adapter null-currentId policy** (matches Task 4's dispatcher policy): dev throws; prod increments `per_session_event_null_current_id` telemetry counter and returns.
