+## [0.42.43.0] - 2026-06-12
+
+**The brain now volunteers relevant pages instead of waiting to be asked (gbrain#2095).** Retrieval used to be pull-only: a deep session could run for hours with zero brain contributions — not because the brain had nothing, but because nothing prompted the agent to ask, and pages stored under coined names were missed by literal-string queries. Push-based context inverts that, on three channels sharing one zero-LLM, confidence-gated core: the ambient retrieval reflex now reads the last few conversation turns (an entity your assistant introduced two turns ago resolves on the "what did she invest in?" follow-up), a new `volunteer_context` operation gives any agent a per-turn volunteer surface over CLI stdin or MCP, and `gbrain watch` streams volunteered pages as a transcript flows through it.
+
+Every volunteered page carries an honest confidence (alias match 0.9, exact title 0.8, slug-suffix 0.6, small boosts for repeated or newest-turn mentions; default gate 0.7) and a one-line rationale. A feedback loop closes the tuning circle: volunteered pages are logged, "used" is derived from whether the page actually got opened afterwards, and `gbrain volunteer-context --stats` reports per-arm precision (labeled approximate, because the open signal is throttled). Suppression learned the difference between a page that was actually surfaced and one merely mentioned — under windowing only a surfaced page is held back, so prior-turn mentions can't silence themselves.
+
+This release also lands on top of v0.42.42.0's exit-contract work as a strict superset: the transaction-mode pooler topology behind three consecutive teardown waves is now reproduced in CI (a real pooler service + an end-to-end teardown test), the exit-verdict sweep is completed across every command surface (notably `gbrain doctor`, whose FAIL verdict could still report exit 0), and a structural guard makes the next raw exit-code write fail in CI instead of silently reporting success on failure.
+
+### Added
+- **`volunteer_context` operation** (CLI: `gbrain volunteer-context`, MCP tool) — pipe recent turns in (`user:` / `assistant:` prefixed lines, or plain text), get confidence-gated page pointers with rationales and synopses out. `--stats` returns the volunteered-vs-used precision summary. Per-call knobs: `max_pages`, `min_confidence`, `session_id`/`turn` attribution.
+- **`gbrain watch`** — the streaming push transport: feed a transcript on stdin, volunteered pages stream out (`--json` for JSONL), each slug at most once per session. Piped input exits cleanly at end-of-input; interactive sessions run until Ctrl-C.
+- **Rolling-window retrieval reflex** — the ambient channel extracts entities from the last 4 turns (configurable via `retrieval_reflex_window_turns` / `GBRAIN_RETRIEVAL_REFLEX_WINDOW_TURNS`; 1 restores the previous single-turn behavior). Assistant-introduced entities and named-antecedent follow-ups now surface pointers with zero agent-initiated queries.
+- **Volunteered-context feedback log** — every volunteered page is recorded (channel, arm, confidence, optional session/turn) with 90-day retention handled by the nightly cycle; rationales are deterministic templates, never raw conversation text. Synopses pass through the same privacy boundary as `get_page`.
+- **Transaction-mode pooler in CI** — the local CI gate now runs a real transaction-pooling service in front of Postgres with an end-to-end teardown test, so the bug class behind gbrain#1972/#2015/#2084 is reproducible before it ships, not after.
+
+### Fixed
+- **`gbrain doctor` exits 1 on FAIL again on every engine.** Its verdict write predated the v0.42.42.0 exit-verdict channel and was being silently zeroed; swept, plus a structural test that fails CI on the next raw exit-code write anywhere in the CLI.
+- **Reflex pointer suppression under multi-turn windows** distinguishes "page already surfaced" from "entity merely mentioned earlier" — without this, window extraction would have suppressed every prior-turn entity by construction.
+
+### To take advantage of v0.42.43.0
+`gbrain upgrade` (applies the new feedback-log migration automatically). The wider reflex window is on by default for context-engine hosts — set `retrieval_reflex_window_turns: 1` in `~/.gbrain/config.json` to restore single-turn behavior. Agents without the context engine: call `volunteer_context` per turn (window in, pointers out), or pipe a transcript through `gbrain watch --json`. After a few days, `gbrain volunteer-context --stats` shows which resolution arms are earning their keep; raise or lower `min_confidence` accordingly.
 ## [0.42.42.0] - 2026-06-12
 
 **`gbrain query` no longer pays a flat 10-second exit tax on managed Postgres behind a transaction-mode pooler — and CLI exit codes finally tell the truth on PGLite.** On deployments where the pooler holds sockets open past the bounded pool drain (gbrain#2084, a residual of gbrain#1972), every query printed its results and then sat for 10 seconds until the force-exit banner fired. The cause was two-layered: the hard-deadline timer was armed *before* the operation handler, so a multi-second search on a large brain burned the teardown budget (and any operation slower than 10 seconds was silently killed mid-run with exit 0 and truncated output); and the CLI never exited explicitly on success — it waited for Bun's event loop to drain, which a stuck pooler socket can hold open forever.
