Trust scores: per (agent, action_type) pair, stored in agent_trust
table. Auto-adjusts when human reacts to AI agent messages (approve
+0.05, reject -0.1). Scores clamped [0.0, 1.0]. MCP get_trust action
+ REST API /api/trust/{agent}. Web UI shows trust progress bars on
agent detail pages.
Claim semantics: only one in_progress reaction per message enforced.
First agent to claim wins, duplicates rejected with clear error.
State-change webhooks: StateChangeNotifier interface fires
workflow.state_changed events through existing webhook infrastructure
when reactions change a message's derived workflow state.
Channel thresholds: publish_threshold and approve_threshold fields
on channels for configuring autonomy gates.
Migration 014_trust_claims.sql. 17 new test cases across trust
model + store.

Add typed reactions (approve/reject/in_progress/done/published) with
toggle semantics. Workflow state derived from highest-priority reaction.

REST API: POST/GET/DELETE /api/messages/{id}/reactions for toggle/query,
PUT /api/channels/{name}/settings for workflow config, GET by-state
endpoint for listing messages by workflow state.
MCP: react/unreact/get_reactions/list_by_state actions via bridge.
Web UI: WorkflowBadge (colored state pills) and ReactionPills (toggle
pills with agent names) components integrated into channel view.
Channel settings: auto_approve, stalemate_remind_after,
stalemate_escalate_after columns. CLI: channels update command.
Migration 013_reactions.sql adds message_reactions table and channel
workflow columns. 29+ new test cases across model and store.

Background worker that detects stale messages and takes corrective action:
- Auto-fails DMs stuck in "processing" after configurable timeout (default 24h)
- Sends system DM reminders for pending messages after ReminderAfter (default 4h)
- Escalates unprocessed messages to #approvals channel after EscalateAfter (default 48h)
- Deduplicates reminders and escalations to avoid spam
- Configurable via SYNAPBUS_STALEMATE_* environment variables

- Auto-join public channels on first send (bug #1)
- Channel broadcasts no longer create duplicate DM copies; inbox DMs
only sent for @mentions (bug #2)
- Embedding pipeline auto-enqueues new messages via MessageListener
callback instead of requiring pod restart (bug #3)
- Admin socket defaults to /tmp in containers to avoid PVC filesystem
incompatibility with Unix sockets (bug #5)
- SSE events now fire for MCP-sent messages (not just REST API),
enabling live notification badges without page reload
- Fixed frontend SSE field name mismatch (channel_name → channel)
- Fixed SSE client not connecting after login redirect

Replace 5 separate tool registrars (messaging, channels, swarm,
attachments, webhooks) with a single HybridToolRegistrar exposing
4 tools: my_status, send_message, search, and execute.
New foundation packages:
- internal/actions: action registry (22 actions) + BM25 search index
- internal/jsruntime: lightweight call() expression parser with
concurrency-limited execution pool
The `execute` tool dispatches call() expressions through a
ServiceBridge that maps action names to existing service methods,
preserving all original handler logic. The `search` tool enables
agents to discover available actions by keyword. The `send_message`
tool merges DM and channel sending with mutual exclusion.
All unit tests, integration tests, build, and vet pass.

- Add embeddings CLI: `synapbus embeddings status|reindex|clear` for
managing vectors when switching embedding providers
- Add automatic message retention worker with configurable period
(--message-retention, default 12m), warning notifications 1 month

Add HNSW-based vector search with configurable embedding providers
(OpenAI, Ollama) and automatic FTS5 fallback when no provider is
configured. Background pipeline embeds messages asynchronously on
ingest, stores vectors in a pure-Go HNSW index, and retries on
failure with exponential backoff. The search_messages MCP tool now
supports search_mode (auto/semantic/fulltext) and returns ranked
results with similarity scores. All existing tests continue to pass,
CGO_ENABLED=0 cross-compilation verified.

tools (send_message, read_inbox, claim_messages, mark_done,
search_messages, register_agent, discover_agents, update_agent,
deregister_agent). SSE transport, health endpoint, connection manager.
- internal/trace: Async trace recorder with buffered channel for
