Garry TanandClaude Fable 5 147f550604 feat(context): reflex consumes the rolling window + ambient-channel logging (#2095)
The default-on retrieval reflex now extracts entities from the last N turns
(retrieval_reflex_window_turns, default 4; env
GBRAIN_RETRIEVAL_REFLEX_WINDOW_TURNS; window=1 reproduces the legacy
current-turn-only behavior exactly). assemble() passes the recent
user/assistant turns (hard cap 12); the reflex slices to the configured
window. Assistant-introduced entities and "what did she invest in?"
follow-ups whose antecedent was NAMED in the window now surface pointers —
the issue's "zero agent-initiated queries" success criterion on the
ambient path.

Under windowing, suppression switches to slug-only (codex D7): the legacy
title-whole-word rule would suppress every entity merely MENTIONED in a
prior window turn, breaking the feature by construction. Slugs only enter
prior context when a pointer/page was actually surfaced, so
already-surfaced pages still suppress. The suppression mode flows through
all three resolver rungs (host opts, serve IPC request, direct Postgres).

Ambient-channel feedback (codex D11): the server-side resolver paths
(serve IPC + direct Postgres) log volunteered pointers with
channel: 'reflex' through the drained volunteer-events sink, so
`gbrain volunteer-context --stats` measures the default-on path where most
volunteering happens. Host-injected resolvers (no gbrain engine) can't
log — documented gap. Precision gates, 1.5s ceiling, fail-open, and the
pointer cap are unchanged.

Tests: prev-assistant-turn entity fires; window=1 legacy parity; slug-only
vs already-surfaced suppression; throwing resolver stays fail-open
(16 green).
