- Add per-tenant TTS configuration endpoints (GET/POST /v1/tts/config)
with RoleAdmin auth instead of master scope
- Implement TenantTTSResolver for channels to use tenant-specific
TTS providers and auto mode settings
- Add per-agent voice override in channel TTS auto-apply:
- Extend OutboundMessage with AgentID and AgentOtherConfig
- Inject AgentAudioSnapshot in dispatch.go from outbound message
- MaybeApply reads tts_voice_id/tts_model_id from agent context
- Fix events.go to use RunContext.TenantID directly (H3)
- Fix dispatch.go error notification to use sendCtx (H1)
- Update UI to use new /v1/tts/config endpoints
The existing tests exercise only the DB fallback path via errorAgentStore.
Add a test that primes the router cache with a stub implementing both
agent.Agent and agentUUIDProvider, then asserts the cache-aware helper
returns the cached UUID without touching the store — the raison d'etre
of the helper. Uses the same sentinel-error store so a broken fast path
surfaces as a sentinel error rather than a silent pass.
Rewrite inline comments added during the agent identity hardening so
they explain the code as it stands today, rather than tying to internal
plan terminology (phase numbers, FR/NFR/H/M/C codes, PR references,
trap zone labels). Commit history already carries the plan archaeology.
Comments now keep the non-obvious invariants (cache boundaries, bypass
gaps, silent-nil traps, dual-tenant semantics) and drop the scaffolding.
Comment-only — no runtime behavior change.
Three-part addition so WS handlers can accept agent_key input without a
DB roundtrip on every request:
1. Router.GetCached — lock-free TTL cache read, no resolver fallback.
2. Loop.UUID() — canonical UUID accessor (agent_key stays on ID()).
3. resolveAgentUUIDCached — fast-path checks router cache via an
agentUUIDProvider interface, falls back to resolveAgentUUID on miss
or when input is a UUID string (un-cached post-canonicalization).
Helper delegates to pure DB lookup when router is nil, so handlers with
no router dependency still work. Tests cover nil-router, cache-miss, and
UUID-input paths — cache-hit coverage is exercised via downstream handler
integration tests.
Phase 3 foundation (TD-2).
