UAT US8/US7: ASR mishears the wake-name "Dotty", breaking name + state-trigger phrases

[BrettKinny]

Symptom. WhisperLocal ASR repeatedly transcribes the persona name "Dotty" as
something else. Observed this session: Jody, Jodi, Claudia, Donny, Dottie, Duddy.
Because state-trigger phrases and person-tools match on the literal name, the
mis-transcription silently breaks them.

Impact (highest of the session). Cascades into multiple failures:

• US8 "goodnight Dotty" → heard "Good night, Duddy" → sleep trigger never matched, no state_changed → sleep.
• US7 "wake up" (exit security) → sticky-state exit failed; had to force idle from the dashboard.

Expected. "Dotty" transcribes reliably; name-bearing triggers fire.

Actual / log excerpt.

20:05:46 识别文本: Good night, Duddy.        # US8 — no state_changed->sleep followed
20:07:03 识别文本: Dotty, can you take watch phone?
19:48:05 大模型收到用户消息: {"content": "Jody, what's the hardest question?"}
20:01:31 vision ... question=Donny, what do you see right now?

Suggested fixes to explore. ASR hotword/biasing for "Dotty"; fuzzy-match the
name in trigger-phrase detection; or a post-ASR alias map (Dottie/Donny/Duddy/… → Dotty).

Related: #105 (ambient ASR garbage), #135 (ASR runtime migration).

This was generated by AI during triage.

Implemented in draft PR #171: the filmed high-confidence Duddy wake-name substitution now normalizes to Dotty, while common real names such as Donny/Jody/Jodi/Claudia remain untouched. Regression coverage includes sleep-phrase routing and word boundaries.

The US7 wake up attempt was a separate low-confidence ASR miss (Welcome), not a name-alias or state-dispatch failure. A distinct reconnect-state gap discovered during analysis is tracked in #170.

RC verification: replay good night, Dotty and bare wake up on device, confirming ASR text and state transitions. Evidence clip: 2026-07-11-US8-FAIL-phone.mp4.
