+- **✅ KB-BRIDGE RETIRED (`09e4257`) — WT #383 native Tier-3 `reference_knowledge` DEPLOYED as v1.0.0b167.**
+  Operator greenlit the #383 deploy (relayed `01KZ0HPT6J...`); worldtree-dev deployed to :8081+demo, validated
+  `builtin_tools=['reference_knowledge']` on both, pinged live (`01KZ0HTJ5M...`). LIVE-VERIFIED before deletion:
+  Donut called the native tool + grounded in DCC Collapse content in-voice (degrades gracefully on absent content).
+  Deleted `kb_bridge.py` + `test_kb_bridge.py` + the one `server.py` call-site + the SSE keepalive + the bridge-only
+  agent_id plumbing (TurnHandle.agent_id, submit read, index.html turn-body). KEPT `wt.stream_turn`'s memory_context
+  param (inert SDK-parity) + the non-str-content 400 guard. Contract marks slice-3 RETIRED (historical record kept).
+  #382/#383 both closed. **Native tool is strictly better than the bridge** (in-turn, provenance packets, server-side
+  grounding rule, fail-soft, no separate consult). FOOT-GUN (#381): freshly-ingested content needs the
+  restart-after-ingest runbook to be Tier-3-recallable.
+- **✅ Zonos WAV-header fix (`6c3c08b`) — operator-reported "browser wants wav, zonos sends pcm."** The gateway
+  emits a STREAMING wav header (RIFF size @4 + data size both `0xFFFFFFFF` = unknown length); a browser `<audio>`
+  can't play a finite blob with an unknown-length header. `tts.py:_finalize_wav_header` rewrites both size fields
+  with the real byte counts (clip is buffered server-side). Live-verified: `wave.open` decodes it (1ch/16bit/44.1kHz).
+  Booth: `http://10.100.10.50:8090/b/donut-voiced/` (donut-wav-fixed.wav).
 
 **✅ SHIPPED + PUSHED since v0.22.0 (origin at `14bbc2b`):** the worldtree-sdk cutover (#20, **v0.22.0**, 7 slices,
 494 green — the big one) + **bifrost 1.1.5** (`3ef3a5e`, **v0.22.1**) + **worldtree-sdk 1.0.0→1.1.1→1.1.2**
