Two real bugs found via verification (hook didn't fire in live session):
1. UserPromptSubmit block had matcher:"*" — event doesn't support matcher,
non-standard block dropped (claude-code-guide authoritative). Removed →
block now {hooks:[...]} like working observer-stop-hook.
2. stdin field was event.user_prompt; Claude Code sends event.prompt.
Now reads (event.prompt || event.user_prompt) for compat.
Field-fix verified manually with real stdin shape {prompt:...} → #71 pdn-152fz.
Firing fix (matcher) NOT verifiable in-session (hooks load at session start) —
needs restart + next-turn state-file check.
NB stop-gate turn_events field also wrong (Stop sends transcript_path) — separate
follow-up, not on observation critical path (affects chain tracking only).
