a81f7e05e8 v0.42.43.0 feat(context): push-based context (#2095) + teardown-exit hardening (#2084) (#2175)
* fix(cli): exit deliberately after bounded teardown instead of riding the 10s backstop (#2084)

Root cause: bounded teardown (endPoolBounded, #2015) RESOLVES, but lingering
sockets — embedding-provider fetch keep-alive, PgBouncer txn-mode sockets the
bound raced past — keep Bun's event loop alive, so every `gbrain query` paid
a flat 10s tax exiting via the hard-deadline force-exit banner.

Three changes, one contract:

- flushStdoutThenExit (cli-force-exit.ts): when main() resolves and the
  command is not a daemon, exit deliberately — after stdout AND stderr drain
  (writableLength===0, 'drain'-event + poll loop, 2s unref'd guard for a
  blocked pipe). Incident #1959 (force-exit truncating piped stdout) is the
  regression class; pinned by a 256KB real-pipe subprocess test.

- drainThenDisconnect (cli.ts): ONE owner-disconnect helper at all 8 sites
  (op-dispatch, CLI_ONLY fall-through, search dashboard, doctor remediation
  x3, ze-switch, dream, read-only timeout path). Drains the background-work
  registry, then disconnect (best-effort), bounded by the 10s unref'd
  hard-deadline — which is now armed around the TEARDOWN window only, not
  before the op handler (the old placement would have force-killed any op
  slower than 10s). Closes the filed TODOS P3 drain-hoist: six sites
  previously skipped the drain entirely and had no hang timer at all.

- Inner process.exit sweep: mid-handler exits in engine-owning/output-bearing
  paths (status, friction, claw-test, smoke-test, eval cross-modal /
  takes-quality replay / conversation-parser / whoknows-thin, status-thin)
  become process.exitCode + return so they flow through the drains and the
  flush-exit. Pre-engine usage/parse/refusal exits stay as-is.

BrainRegistry.disconnectAll deliberately unchanged: zero production callers
in src/, per-engine disconnects already bounded, and the kernel reclaims
sockets on exit (src/core/timeout.ts doctrine).

DAEMON_COMMANDS gains 'watch' ahead of the #2095 push transport.

* test(e2e): PgBouncer transaction-mode pooler in CI + teardown e2e (#2084)

Three consecutive waves (#1972#2015#2084) fixed pooler-teardown bugs
verified only against one production deployment — CI had no transaction-mode
pooler and could never see the class. Now it can:

- docker-compose.ci.yml: `pgbouncer` service (transaction pooling) fronting
  postgres-1, mirroring the production split-pool topology (direct :5432 +
  pooled :6543). AUTH_TYPE=plain (pg16 SCRAM verifiers need the plaintext
  password in the userlist) + IGNORE_STARTUP_PARAMETERS for the
  statement_timeout/idle_in_transaction_session_timeout startup params
  gbrain's client sets (the Supabase pooler whitelists the same).
- test/e2e/pgbouncer-teardown.test.ts: schema + fixture via the DIRECT url
  into a dedicated `gbrain_pgbouncer` database (never races shard TRUNCATEs),
  then spawns the real CLI against the POOLED url and asserts: exit 0,
  stdout intact (the #1959 truncation class), and NO
  "did not return within 10000ms — force-exiting" banner (pre-#2084 it
  printed on 100% of query-shaped ops on this topology). Class bound, not
  exact timing. Skips gracefully without GBRAIN_PGBOUNCER_URL.
- scripts/ci-local.sh: threads GBRAIN_PGBOUNCER_URL +
  GBRAIN_PGBOUNCER_DIRECT_URL into all three e2e phases.

Verified live: both tests green against pgbouncer 1.25.2 in transaction mode.

* feat(schema): context_volunteer_events table (v116) — push-context feedback log (#2095)

One row per page the brain volunteers (op / reflex / watch channels).
"Used" is DERIVED, never written: pages.last_retrieved_at > volunteered_at
(the existing bumpLastRetrievedAt write-back is the open/cite signal), so
there is no second tracking path. session_id/turn are nullable
caller-supplied attribution; rationale is a deterministic template string,
never raw conversation text.

- Migration v116 (idempotent) + mirrors in src/schema.sql +
  src/core/pglite-schema.ts + regenerated schema-embedded.ts (regen also
  folds in pre-existing comment-only drift from the v114 links edits).
- src/core/context/volunteer-events.ts: insertVolunteerEvents (ONE
  multi-row parameterized INSERT — never per-row awaited round-trips) +
  purgeStaleVolunteerEvents (90-day GC, returns 0 on pre-v116 brains).
- Dream cycle purge phase prunes stale events alongside op_checkpoints /
  brainstorm checkpoints / batch-retry audit files.
- RLS on Postgres comes from the v35 auto_rls_on_create_table event
  trigger (the same mechanism that covered v110 page_aliases and v115
  op_checkpoint_paths); the volunteer Postgres e2e pins it.
- No ::jsonb anywhere; no bootstrap probe needed (nothing references the
  table pre-creation; writers guard with try/catch).

Tests: v116 shape + columns + indexes + live insert/purge round-trip on
PGLite (test/migrate.test.ts, 161 pass); schema-bootstrap-coverage green.

* feat(context): multi-turn window extraction + confidence-scored volunteer core (#2095)

- entity-salience.ts: extractCandidatesFromWindow(turns) — runs the existing
  per-turn extractor across the last N turns (oldest→newest), merges by the
  normalizeAlias form with occurrence/newest-turn/user-mention metadata, and
  orders by salience (recency > frequency > user-role) so the MAX_CANDIDATES
  cap drops stale assistant chatter, not the entity the user just named.
  Closes the filed assistant-introduced-entities recall TODO; true pronoun
  coreference (never-named antecedents) stays out of scope.

- retrieval-reflex.ts: ReflexPointer gains source_id + arm + confidence +
  matchedNorm. ARM_CONFIDENCE (alias 0.9 / title 0.8 / slug-suffix 0.6)
  lives next to the arm definitions so identity and score can't drift.
  Arm-2 provenance is classified in JS (codex D8 — the combined OR can't
  report which predicate matched). Federated sourceIds[] scope (alias arm
  loops per source; arm 2 uses source_id = ANY — no engine-interface
  change). Suppression gains 'slug-only' mode (codex D7, REQUIRED for
  windowing): 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 context when a pointer/page was actually
  surfaced. Default stays 'slug-and-title' for the window=1 legacy path.

- volunteer.ts (new): parseWindow (lenient user:/assistant: prefixes, CRLF,
  unprefixed → one user turn), volunteerContext (zero-LLM: extract →
  resolve → +0.05 multi-turn/newest-turn boost → min_confidence 0.7 gate →
  cap 3/5; deterministic rationale strings, never raw conversation text),
  and volunteerUsageStats (per-arm/channel precision from the
  last_retrieved_at join, labeled approximate — 5-min throttle false
  negatives, unrelated-read false positives; codex D9).

Tests: 35 green across volunteer-context (window parsing, pronoun follow-up
via assistant-introduced entity, confidence gating, slug-only suppression,
takes-fence privacy, multi-source scope, caps, stats join math) +
retrieval-reflex back-compat + resolve-ipc.

* feat(ops): volunteer_context op — CLI (stdin) + MCP, drained event sink (#2095)

New read-scope op on the contract surface (CLI `gbrain volunteer-context`
with stdin → window, MCP tool for free): takes a rolling conversation
window, returns confidence-gated page pointers with rationales + synopses.
`window` is optional-unless-stats (validated in the handler, codex D9);
`stats: true` returns the volunteered-vs-used precision summary, labeled
APPROXIMATE (the 5-min last-retrieved throttle and unrelated reads both
bias the join). Source scope threads through sourceScopeOpts — federated
grants narrow the volunteer to the granted sources.

Event logging is fire-and-forget through a new `volunteer-events`
background-work sink (volunteer-events.ts, mirrors last-retrieved: tracked
dangling promise set + bounded drain + snapshot-drop on timeout so a
long-lived process never accumulates ghosts). ONE batched INSERT per call,
drained on every exit path by the commit-1 drain hoist; failure never
fails the op (pinned by an injected failing-engine test).

cli formatResult renders both shapes (pointer lines with confidence/arm/
rationale; the stats summary with per-arm precision).

Tests: op contract surface, window-required validation, sink round-trip
with session_id/turn attribution, failing-engine fail-open, federated
grant scoping, stats mode (26 green on PGLite) + a real-Postgres e2e
proving the op + sink + stats join AND that context_volunteer_events has
RLS enabled (keeps the auto-RLS event-trigger mechanism honest for v116).

* 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).

* feat(cli): gbrain watch — push transport over stdin (#2095)

The issue's headline: the brain volunteers pages as the conversation flows,
instead of waiting to be asked. `some-transcript-feed | gbrain watch` reads
turns line-by-line ('user:'/'assistant:' prefixes set the role; unprefixed
lines are user turns), keeps a rolling window (--window-turns, default 4),
and streams confidence-gated pointers with rationales to stdout (--json for
JSONL). Session dedupe rides the core's slug-only suppression — a slug is
volunteered at most once per session. Events log on channel 'watch' with
session_id + turn through the drained sink.

Lifecycle: watch BLOCKS in the stdin iteration (like `jobs work`) — an
interactive TTY stays alive until Ctrl-C/Ctrl-D, piped input ends at EOF —
so it is deliberately NOT in DAEMON_COMMANDS (reverts the commit-1
placeholder): when main() resolves the work is over, the CLI_ONLY finally
drains volunteer events via drainThenDisconnect, and the entrypoint
flush-exit ends the process. Keeping it in the daemon set would have made
the piped EOF path hang on lingering sockets — the exact #2084 class.
SIGINT closes the stream and flows through the same drain path instead of
killing mid-write. Per-turn resolution failures are fail-open (the stream
never dies on a transient DB error).

Full wiring (eng-review D12): CLI_ONLY + CLI_ONLY_SELF_HELP (WATCH_HELP) +
THIN_CLIENT_REFUSED_COMMANDS (thin clients use the volunteer_context MCP
op) + main --help entry.

Tests: 18 green — help, per-turn volunteering + clean EOF return, rolling
window via assistant-introduced entity, session dedupe, --json shape with
turn attribution, channel-watch event rows, --min-confidence gate, CRLF/
blank tolerance, daemon-gate semantics. Live smoke: piped `gbrain watch`
on a fresh PGLite brain exits 0 at EOF with no force-exit banner.

* docs: KEY_FILES + push-context guide + TODOS for the #2084/#2095 wave

- docs/architecture/KEY_FILES.md (current-state): context entries gain the
  window extractor, arm provenance/confidence, suppression modes, volunteer
  + volunteer-events modules; background-work entry now lists FIVE sinks and
  the drainThenDisconnect owner-disconnect contract; new entries for
  src/core/cli-force-exit.ts (the exit contract) and src/commands/watch.ts.
- docs/guides/push-context.md (new): the three channels (reflex/op/watch),
  the confidence model, CLI usage, config keys, and the approximate-stats
  caveat. Linked from CLAUDE.md's reference map.
- CLAUDE.md: ops line mentions volunteer_context + the guide link;
  bun run build:llms regenerated in the same commit (freshness test green).
- TODOS.md: #2095 deferrals filed (SSE push channel, policy skill + doctor
  check, structured messages[] param); the #1981 entity-detection TODO
  narrowed (window extraction covered assistant-introduced entities +
  named-antecedent follow-ups); the drain-hoist P3 marked DONE by the
  #2084 wave.

* test(e2e): truncate context_volunteer_events in setupDB (#2095)

The new feedback-log table wasn't in ALL_TABLES, so volunteered-event rows
persisted across e2e runs on a reused database and poisoned count/stats
assertions in volunteer-context-postgres on the second run. No FK to pages
(slug join), so position before pages is for hygiene only.

* fix(cli): own the exit verdict — never trust ambient process.exitCode (#2084)

Caught by the full unit suite: `gbrain apply-migrations` on PGLite started
exiting 99. Root cause: PGLite's Emscripten runtime writes the WASM
backend's proc_exit status into process.exitCode (initdb at create-time,
the postmaster at close-time — `exitCode=status` in pglite's dist), and
the writes land ASYNCHRONOUSLY, outside any snapshot/restore window around
create/close (a guarded attempt verified this). The pre-#2084 success path
never read process.exitCode, so the pollution was invisible; the new
deliberate flush-exit propagated it faithfully.

Fix: gbrain records its own verdict. setCliExitCode(n)/getCliExitCode() in
cli-force-exit.ts — every gbrain-owned exit-code assignment routes through
the setter (still mirrored to process.exitCode for outside readers), and
both exit paths (entrypoint flushStdoutThenExit + the drainThenDisconnect
hard-deadline backstop) read the getter. Swept all assignment sites:
cli.ts (op error, friction, claw-test, smoke-test, eval runners, status,
import errors) + reindex/transcripts/brainstorm/frontmatter/autopilot.

Also updates the v0.42.20 structural pins to the drainThenDisconnect shape
(ordering invariant asserted INSIDE the helper + >=8 helper call sites,
superseding the two-inline-pairs assertion).

Verified: apply-migrations spawn test green; `init --migrate-only` exits 0;
an errored op still exits 1.

* test: re-pin the teardown-arming invariant at its post-#2084 home

Master's v0.42.41.0 triage wave and the #2084 wave fixed the same
pre-armed-timer bug independently; the merge keeps #2084's shape (arming
inside the shared drainThenDisconnect helper, covering all 8 exit paths).
The structural pin now asserts the same invariant — no pre-try arming;
gated, unref'd, before-drain, cleared — at the helper.

* test: coverage for ambient reflex-channel logging + watch window/cap flags

Ship coverage audit (85%, gate PASS) named five gaps; the two substantive
cheap ones close here: the codex-D11 logChannel='reflex' path now has a
behavioral pin (events land on channel 'reflex' through the drained sink;
no logChannel → no events), and gbrain watch's --window-turns / --max-pages
flags are exercised (turn-1 attribution under window=1; cap to one page).
Remaining flagged-not-blocking: the wallclock-timeout branch (untestable
without >10s real-clock flake — same rationale as the arming pin),
formatResult's volunteer case (module-private), and the cycle purge wiring.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* test: close the remaining plan-audit gaps — formatResult rendering + watch SIGINT

formatResult exported for tests (same import-safety contract as cliAliases);
test/cli-format-volunteer.test.ts pins the pointer lines, empty-gate message,
and approximate stats summary. test/watch-command.test.ts gains a real
subprocess SIGINT test: piped stdin that never reaches EOF, SIGINT mid-stream,
assert exit 0 with no force-exit banner — the drain-then-exit lifecycle under
the actual signal, not just the shared exit path.

* fix: doctor's FAIL verdict was zeroed by the owned exit — sweep stragglers + class pin

The merged-state suite caught it: doctor --fast --json reported FAIL but
exited 0. Master's v0.42.41.0 brought raw `process.exitCode =` writes
(doctor.ts hasFail ternary, extract.ts) that the #2084 verdict-owning exit
silently zeroes — getCliExitCode() deliberately never reads ambient
process.exitCode (the PGLite-Emscripten pollution defense), so any setter
that bypasses setCliExitCode reports success on failure.

Swept both sites and added the structural class pin: a test greps src/ for
raw `process.exitCode =` outside cli-force-exit.ts, so the next merge that
introduces one fails loudly instead of lying about exit codes.

* chore: bump version and changelog (v0.42.43.0)

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* test: quarantine the watch SIGINT subprocess test to the serial lane

The parallel unit shards flake on concurrent CLI subprocess spawns (failed
at 7ms in-suite, green solo) — same isolation rationale as
apply-migrations-pglite-spawn.serial.test.ts and #2141's R3 quarantine.

* docs: update project documentation for v0.42.43.0

Post-ship doc verification against the release diff (#2095 push-based
context + #2084 superset hardening), with a cross-model doc review:

- push-context.md: version tag corrected to v0.42.43.0; per-call knobs
  now cover prior_context/days and watch's flag surface accurately;
  feedback-log writes described as best-effort; synopsis fence-strip
  described as unconditional.
- CLAUDE.md: stale operation count (~47 -> ~90); volunteer_context
  release reference corrected to v0.42.43.0.
- KEY_FILES.md: ci-local entry rewritten to current topology (4-shard
  parallel default, four Postgres services, transaction-mode PgBouncer
  + GBRAIN_PGBOUNCER_URL/_DIRECT_URL exports); stale E2E file counts
  dropped from the selector entry.
- TESTING.md: inventory entries for the new #2084 structural pins
  (cli-exit-verdict-pin, cli-pipe-truncation), the push-context test
  suite (volunteer-context, watch-command, watch-sigint.serial,
  cli-format-volunteer), migrate v117 coverage, and the two new E2E
  files (pgbouncer-teardown env gating, volunteer-context-postgres RLS
  pin); check:all row corrected (not a superset of verify).
- AGENTS.md + RELEASING.md: ci:local descriptions updated to the
  sharded + pooler topology.
- CHANGELOG (wording only, entry preserved): "retrieved" instead of
  "opened" for the used-signal, pooler scoped to the local CI gate,
  feedback log labeled best-effort.
- llms-config.ts: index the new push-context guide; bundles
  regenerated (build:llms) and freshness test green.

* docs(test): correct the v116 reference — the table shipped as migration v117

* fix: pre-landing review hardening — federated alias parallelism, trust-boundary clamps, shared protocol helpers (#2095)

Five specialist reviewers (testing/maintainability/security/performance/
data-migration) on the reconciled diff; every finding applied:

Performance: the alias arm now resolves all granted sources CONCURRENTLY
(a federated caller paid M sequential RTTs per turn — ~355ms at 5 sources
cross-region, inside the reflex's 1.5s budget); watch's session dedupe is
O(1) Set membership instead of a monotonically growing priorContext string
(O(T²) over a long-lived session); getWindowTurns iterates from the tail
(per-turn cost no longer grows with session length); the resolver's
provenance maps fold into the existing candidate pass.

Security: volunteer_context clamps caller-supplied attribution at the trust
boundary — session_id capped at 256 chars (a read-scoped token could bank
~1MiB TEXT per request, retained 90 days), turn logged only when a safe
integer (a non-integer threw inside the batched INSERT and silently dropped
the whole batch). The privacy comments now state precisely what rationale
may contain (the matched entity's surface form — which by construction
resolved to an existing alias/title/slug — never free conversation text).

Maintainability: TURN_PREFIX_RE + formatVolunteeredPage exported from
volunteer.ts and shared by watch/cli (the two surfaces can no longer
drift); volunteerEventRowsFrom is the single VolunteerEventRow assembly
site for all three channels; watch's window default now honors the same
retrieval_reflex_window_turns config knob the reflex reads; the stale
pre-v116 comments swept to pre-v117.

Testing: the two flake-class CRITICALs fixed (pipe test asserts the
backstop banner instead of a cold-CI-hostile 9s wall bound; the SIGINT test
waits on watch's new machine-readable ready line instead of a fixed 15s
sleep — 2.5s and deterministic now); new coverage for the sink's timeout
branch + ghost-reference drop, watch per-turn fail-open, untrusted knob
clamps (min_confidence/max_pages/days), window-cap ordering (newest user
mention survives), serve-IPC suppression passthrough + channel=reflex
logging, windowTurnCount edge semantics, and structural pins for the sink
registration + cycle purge wiring. The exit-verdict pin's grep is now
operator/whitespace-tolerant.

Deferred with TODOs: resolver index shapes for the per-turn query;
batched first-prune after a long dream-cycle gap.

* fix(context): red-team hardening — pre-cap dedupe, delivery-side reflex logging, window clamp

Four red-team findings on the #2095 push-context surface:

- RT1 starvation: watch's session-dedupe Set filtered AFTER volunteerContext's
  cap, so a recurring already-pushed entity burned cap slots every turn and
  starved fresh pages behind it. VolunteerOpts.excludeSlugs now skips inside
  the pointer loop BEFORE the confidence gate and the cap.
- RT3 honest stats: reflex-channel event logging moved from inside the
  resolver to the DELIVERY point — serve's resolve-IPC onDelivered hook fires
  only after the response write succeeds, and buildReflexAddition logs only
  after the per-turn timeout admits the block. A block the client's 250ms
  budget abandoned was never injected and no longer counts as volunteered.
  (logChannel resolver opt removed; logDeliveredReflexPointers is the seam.)
- RT5 unbounded window: --window-turns is clamped to [1, 64] so a config typo
  can't reintroduce the re-scan-everything-per-turn cost class.
- RT2/RT4 documented + filed: PGLite watch connection monopoly (WATCH_HELP,
  push-context guide, TODO to route watch via serve IPC); host-resolver
  suppression contract at ResolveEntitiesFn (TODO for a capability gate).

Tests: starvation guard (watch + volunteerContext unit), window clamp floor +
ceiling, delivery-side logging (helper writes channel=reflex through the
drained sink; bare resolver writes nothing; empty list no-op), IPC wiring test
rewired to onDelivered. KEY_FILES.md + push-context.md updated; build:llms run.

* fix(context): env-plane window knob works config-less; harden two gateway-state-leak victims

Three CI-only check failures, two root causes:

1. windowTurnCount ignored GBRAIN_RETRIEVAL_REFLEX_WINDOW_TURNS when
   loadConfig() returned null (no config file AND no DATABASE_URL — a clean
   CI shard with no brain). loadConfig drops its env→config mapping in that
   case, so the documented escape hatch silently died and the window fell
   back to 4 → windowed extraction widened when the test set window=1 →
   prior-turn entity leaked. Fixed: read the env var directly in
   windowTurnCount, mirroring reflexEnabled's direct process.env read. This
   is a real product bug, not just a test artifact — any config-less host
   using the env hatch was affected. Regression test pins it.

2. sync-cost-preview + doctor-federation-health failed only IN-SHARD: a
   sibling test configured a non-legacy (ZeroEntropy 1280-d / $0.05) gateway
   and never reset it. The legacy-embedding preload only restores the
   OpenAI/1536 default when the gateway slot is EMPTY, so a non-empty foreign
   config survives into the next file — and a file's beforeAll runs BEFORE
   the preload's restoring beforeEach, so federation-health built a
   vector(1280) column and its 1536-d fixture hit CheckExpectedDim. My new
   test files reshuffled the deterministic file→shard assignment, exposing
   this latent ordering bug. Hardened both victims to establish the gateway
   state they assert (sync-cost-preview resets to the unconfigured fallback;
   federation-health pins legacy 1536 before initSchema) so they're
   order-independent. Verified against a simulated leaker run before them.

* test(context): use withEnv() in the window env-hatch test (test-isolation guard)

The regression test added in 82cc7fff mutated process.env directly, which
check:test-isolation (R1) forbids — use the withEnv() helper that restores on
exit, same as the rest of this file. Behavior identical; guard green.
