Sorry, something went wrong.
1. Mute filter now only suppresses message events (message.created, message) System/control events (channel.updated, member.joined, member.left, mute/unmute confirmations) are delivered to all members including muted. 2. Added mute/unmute endpoints to openapi.yaml per AGENTS.md mandate. 3. E2E: Handle 'agent already exists' by deregistering and re-registering. Fixes Deploy Preview CI failure when preview workspace has stale agents from previous runs.

1. E2E: Use relay.agents.delete() instead of non-existent deregister(). Fixes 'already exists' error in Deploy Preview when stale agents remain. 2. OpenAPI mute/unmute fixes (Devin review BUG_0002/0003/0004): - Response wrapped in 'data' envelope matching implementation - Security: agentToken only (removed workspaceKey — impl uses requireAgentToken) - Removed requestBody (impl derives agent from token, not body) - Added 403 for not-a-member error

1. Local Rust server: add mute_channel/unmute_channel handlers + routes. Adds channel_muted HashSet to Store. Parity check now passes (73/73). 2. E2E: use agents.delete() (not deregister which doesn't exist), fall back to agents.release(delete_agent: true), add 500ms propagation delay, and log cleanup failures for debugging.
D1 replication lag means delete may succeed but register still sees the old record. Retry up to 3 times with 1s/2s/4s backoff between delete and re-register attempts.

…ncy) Root cause: registerAgent did SELECT-then-INSERT. On D1 with read replicas, the SELECT could hit a stale replica that still sees a deleted agent, while the INSERT goes to the primary. This caused false 'already exists' errors when re-registering agents after deletion. Fix: INSERT directly and let the unique index (workspace_id, name) enforce uniqueness. Catch UNIQUE constraint violations and convert to the same 409 error. This is atomic and immune to read replica lag. Also simplified E2E: fallback to registerOrRotate (the server-supported idempotent path) instead of delete+retry loops.

Server: 1. DB migration 0003 for is_muted column on channel_members 2. Clear mute cache on channel leave (prevents mute-leave-rejoin bug) 3. Suppress thread.reply events for muted members (not just message.created) 4. registerAgent: INSERT-first with unique constraint catch (D1 TOCTOU fix) Local Rust server: 5. Fix double-wrapped response envelope in mute/unmute handlers 6. Add #[serde(default)] on channel_muted (backward compat with old snapshots) 7. Enforce mute in WebSocket delivery path (check channel_muted for message events) E2E: 8. Use registerOrRotate as fallback (server-supported idempotent path)
The is_muted column (migration 0003) doesn't exist on staging D1 because preview deployments skipped migrations. This caused ALL agent registration to fail since drizzle includes is_muted in channel_members INSERT statements. Added apply-d1-migrations step to preview workflow. The migration action is idempotent (wrangler tracks applied state) so safe to run on every preview deploy.
Migration 0003: ALTER TABLE channel_members ADD COLUMN is_muted INTEGER NOT NULL DEFAULT 0 Prepares the schema for the mute/unmute feature (PR #100). No code references this column yet — purely additive migration.

🐛 Missing transformForClient cases for mute/unmute events delivers malformed WebSocket events (packages/server/src/engine/wsTransform.ts:214-217)
The wsTransform.ts transformForClient function has no explicit cases for member.channel_muted or member.channel_unmuted. These events fall through to the default case (packages/server/src/engine/wsTransform.ts:214-216) which spreads raw data fields as-is. The route sends { channel_name: name, agent_name: agent!.name } as event data (packages/server/src/routes/channel.ts:579), so clients receive channel_name instead of channel. But the Zod schema (packages/types/src/events.ts:152-156) and the SDK type ChannelMutedEvent expect channel, not channel_name. The analogous member.joined and member.left events (packages/server/src/engine/wsTransform.ts:159-171) have explicit transform cases that map d.channel_name → channel — the new events need the same treatment. Without this, all WebSocket mute/unmute events fail schema validation and SDK subscribers will see undefined for the channel field.

🔴 ChannelDO queries D1 for muted members on every broadcast when nobody is muted
In handleBroadcast, the muted-member cold-start fallback checks (await this.getMutedMembers()).length === 0 to decide whether to load from D1. Unlike the analogous member-loading check (which only fires for 0-member channels that rarely receive broadcasts), a channel with zero muted members is the overwhelmingly common case. After the first broadcast sets this.mutedMembers = [], subsequent broadcasts still see length === 0 and re-query D1 via loadMutedFromDb on every single broadcast — adding an unnecessary DB round-trip per message for every active channel. The fix is to use a separate boolean flag (e.g., mutedMembersLoaded) to distinguish "not yet loaded" from "loaded and empty", consistent with the null vs [] pattern already used by getMutedMembers() for the storage layer.

D1 puts constraint errors in .code ('SQLITE_CONSTRAINT_UNIQUE'),
not in the message string. Match both D1 and SQLite error formats
so duplicate registration returns 409 with 'agent_already_exists'
instead of a raw transport_error.

D1 and drizzle wrap SQLite constraint errors in different ways: - D1: .code = 'SQLITE_CONSTRAINT_UNIQUE' - D1 message: 'D1_ERROR: UNIQUE constraint failed: ...' - Drizzle: may nest original error as .cause Added isUniqueConstraintError() that checks .code, .message (case- insensitive), and recursively checks .cause for drizzle wrapping.

1. Local leave_channel clears muted state (prevents mute-leave-rejoin bug) 2. ChannelDO fanOut short-circuits mute filtering when nobody is muted (avoids Set creation and filter on every broadcast) 3. Robust unique constraint detection with recursive .cause checking
