Merge origin/master (v0.46.3.0) into garrytan/opencode-support

Trio kept at 0.46.4.0 (wave version, highest); CHANGELOG carries both
entries with 0.46.4.0 topmost; template-repo + flag registry regenerated;
llms rebuilt.

+
+**opencode joins the supported-client roster — at full parity from day one.**
+(opencode is opencode.ai, SST's terminal agent — not OpenClaw.) Unlike earlier
+clients that started with a manual recipe, opencode lands with every install
+lane gbrain has: the paste-in workspace bootstrap, machine-level harness
+wiring, `gbrain connect`, a claw-test runner, and a real-binary e2e door in
+CI. Every asserted flag, config shape, and quirk was observed against a
+pinned install (opencode 1.18.18), recorded in a machine-checked pin
+document, and exercised against the real binary — including the part that
+makes opencode special: its keyless anonymous free tier drives MCP tool
+calls, so the end-to-end proof needs zero secrets.
+
+### Added
+- **`gbrain bootstrap hooks --harness opencode`** — workspace-lane MCP
+  registration via direct, comment-preserving JSONC writes (never a CLI
+  exec, works offline). MCP scope is honored with a deliberately INVERTED
+  default: user-global, because opencode spawns project-config servers with
+  no trust prompt; project scope is an explicit opt-in that prints a sharing
+  warning. A structural ownership fingerprint refuses to touch entries
+  gbrain didn't write.
+- **`gbrain bootstrap harness --harness opencode`** — machine-level remote
+  MCP wiring with an inline bearer written 0600, token rotation across URL
+  changes, content-guarded rollback on failed smoke, `--status` and
+  `--remove`.
+- **`gbrain connect --agent opencode [--install]`** — env-interpolated
+  bearer (`{env:GBRAIN_REMOTE_TOKEN}`): the token never enters the config
+  file. `--force` replaces a registration whose endpoint moved.
+- **`gbrain claw-test --agent opencode`** and a split-gated real-binary e2e
+  door in CI: keyless tier (version pin, install + `mcp list` handshake,
+  spawn-gate canary, writer parity, MCP SMOKE on the free tier) plus a paid
+  Anthropic leg that model-gates before spending; npm supply-chain
+  provisioning verifies the actual downloaded tarball bytes against pinned
+  integrities; a schedule-only canary tracks the latest upstream release.
+- **Docs:** `docs/mcp/OPENCODE.md` install guide,
+  `docs/mcp/OPENCODE-CLI-PIN.md` observation pin (with a verify-time drift
+  guard and a pin-refresh cadence), roster updates across README / INSTALL /
+  bootstrap guides. opencode reads the rendered AGENTS.md pull-protocol
+  contract natively.
+
+### Changed
+- The bootstrap config writers (Claude hooks JSON, Codex TOML, opencode
+  JSONC) now share one atomic-write helper; symlinked configs — including
+  dangling dotfile-manager links — survive writes as links.
+- The door-test family (binary resolution, hermetic child envs, one-shot
+  spawns) extracted into shared factories; the hermes and grok runners were
+  ported onto them, hermes child envs gained the GitHub step-metadata scrub,
+  and the hermes installer pin was refreshed (its nightly door had gone red
+  on upstream installer drift).
+- A new pin-doc privacy guard asserts every agent pin document ships with
+  placeholder paths and no key material.
+
+### Fixed
+- Security and robustness hardening from the pre-landing cross-model review
+  pass: registration verification probes run isolated and time-bounded, and
+  a hung probe is killed instead of abandoned; global config writes
+  reconcile both opencode global filenames under the bootstrap lock; config
+  backups are unique per operation with content-guarded restore; error
+  paths never echo credentials; test-harness child processes drop CI
+  credentials before spawning third-party binaries.
+
+### To take advantage of v0.46.4.0
+opencode users: run `gbrain bootstrap hooks --harness opencode` in your
+brain workspace (or paste the standard bootstrap block into an opencode
+session). The keyless free tier is enough to verify the wiring end to end —
+`opencode mcp list` should show `✓ gbrain connected`. Existing installs:
+nothing changes; this release adds a client, it doesn't modify brain
+behavior.
+## [0.46.3.0] - 2026-08-15
+
+**ZeroEntropy is shutting down on 2026-09-04 — gbrain now gets you off it
+before that date costs you retrieval.** The provider that shipped as the
+default embedding + reranking stack from v0.36 through v0.46 is winding down
+its hosted API. This release makes the transition a guided, one-command move
+instead of a surprise outage:
+
+- **New default: Voyage.** Fresh installs land on `voyage:voyage-4` (1024d) —
+  the strongest hosted retrieval embedder on current benchmarks — and the same
+  `VOYAGE_API_KEY` powers the new `voyage:rerank-2.5` reranker (written as
+  explicit config whenever a Voyage key is present at init; keyed installs
+  without one get reranking explicitly disabled instead of inheriting a
+  fallback they can't use) and the multimodal model. One key, all three
+  touchpoints. The v4 family shares one embedding space, so you can later
+  point queries at `voyage-4-large` or `-lite` without re-indexing.
+- **Nothing changes out from under existing brains.** A brain configured for
+  ZeroEntropy (or riding the old default) keeps working exactly as before until
+  the shutdown date — this release only detects, warns, and hands you the
+  playbook. Every surface that used to steer you toward the dying provider
+  (init auto-pick, the interactive picker, `gbrain providers`, setup hints)
+  now steers you to the replacement instead, and using it prints a
+  once-per-process heads-up.
+- **The switch is one command:** `gbrain migrate embeddings --to voyage:voyage-4
+  --dim 1024 --dry-run` (cost preview), then `--yes`. Prefer OpenAI? It can
+  keep your existing column width: `--to openai:text-embedding-3-small
+  --dim 1280`. Reranker: `gbrain config set search.reranker.model
+  voyage:rerank-2.5`. Self-hosting the Apache-2.0 weights remains documented in
+  docs/guides/embedding-migration.md.
+- **Your agent gets told too.** A v0.46.3 migration checks whether your brain
+  still resolves to the sunsetting provider (embedding, reranker, or custom
+  columns), prints an ACTION REQUIRED notice with the blast radius and cost
+  estimate, and files a durable action item pointing at the agent playbook
+  (`skills/migrations/v0.46.3.0.md`). `gbrain doctor`'s provider check now
+  prints width-aware paste-ready commands, and its documented suppression
+  switch (`gbrain config set doctor.suppress_provider_sunset true`) actually
+  works now.
+- `gbrain ze-switch` no longer switches brains onto the sunsetting provider
+  (`--undo` still moves brains off it), and `gbrain migrate embeddings` refuses
+  a re-embed onto a provider with an announced shutdown — self-hosters with a
+  wire-compatible endpoint pass `--force-sunset-target`. Voyage's
+  `voyage-code-4` is available for code-heavy brains.
+- Setup fixes that ride along: init now detects provider keys stored in
+  `~/.gbrain/config.json` (file plane), not just env vars; a keyless brain
+  upgrades in place via `gbrain init --force --embedding-model voyage:voyage-4`
+  (the deferred-setup sentinel is cleared); and keyless fresh installs size the
+  embedding column at the new default width.
+
+### To take advantage of v0.46.3.0
+
+`gbrain upgrade` is enough — no schema migration.
+
+1. **Upgrade and check:**
+   ```bash
+   gbrain upgrade
+   gbrain doctor
+   ```
+2. **If the upgrade printed ACTION REQUIRED** (or doctor flags
+   `provider_sunset`): run the printed migrate command before 2026-09-04, or
+   hand your agent `skills/migrations/v0.46.3.0.md` — it walks the whole
+   switch, including the reranker and edge cases.
+3. **Things to watch:** existing brains see zero behavior change from this
+   release itself; fresh installs default to `voyage:voyage-4` at 1024
+   dimensions; reranking configured on the sunsetting provider dies with it on
+   2026-09-04 unless you set the voyage reranker (or disable reranking). If
+   anything looks wrong, file an issue with `gbrain doctor` output:
+   https://github.com/garrytan/gbrain/issues

+## [0.46.2.0] - 2026-08-15
+
+**Dream synthesis now triages before it spends.**
+([#4152](https://github.com/garrytan/gbrain/issues/4152)) The synthesize
+phase used to point its most expensive model at every transcript that
+cleared a yes/no check — on a busy brain that meant an unbounded queue of
+long frontier-model jobs grinding through logistics and small talk. It is
+now a two-stage cascade: a cheap scored triage reads every file first, and
+only what scores above your threshold reaches the synthesis model, which
+starts from a map of the noteworthy passages instead of hunting through raw
+transcript.
+
+### Added
+- **Scored triage gate.** Every transcript gets a 0–1 salience score,
+  content type, candidate quotes, and entity candidates from the utility-tier
+  model (one call per new file, cached in `dream_verdicts` with the judging
+  model + prompt version — migration v129). The gate
+  (`dream.triage.threshold`, default 0.5) is applied at read time: retune it
+  any time and re-gating costs **zero** new LLM calls. Provider hiccups
+  (truncation, refusal, unparseable output) are never cached as rejections —
+  those files are re-judged next cycle, and an outage reports as "triage
+  degraded", never as "everything scored low".
+- **`gbrain dream retriage`** — re-score the corpus and reconcile the queued
+  synthesis backlog. `--dry-run` previews from cached scores with zero LLM
+  calls; `--reconcile-queue` cancels queued jobs that score below the gate
+  AND converts jobs stranded in dead per-run queues so the next cycle
+  actually re-submits them; `--audit-rejects <n>` gets a frontier-model
+  second opinion on a sample of rejects (the threshold-calibration loop).
+  Every sweep prints an upfront cost estimate and asks before spending more
+  than a few dollars (`--yes` to skip, `--max-usd` for an estimate-based
+  budget stop that counts every paid call, including unreliable ones — it
+  can overshoot by up to the configured triage concurrency). Guardrails: queues
+  younger than an hour are treated as possibly-live and never touched;
+  `--cancel-unmatched` refuses to run off a truncated or empty corpus scan.
+- **Triage map in the synthesis prompt.** Passing files hand the synthesis
+  subagent their pre-extracted quotes and entities (verbatim-verified against
+  the chunk text) so it works from signal instead of re-scanning sludge.
+- **Cost knobs.** `dream.synthesize.max_turns` (default now 16, was a
+  hardcoded 30 — set it back via config if your written-page counts drop;
+  `details.synthesis.avg_turns` shows cap pressure),
+  `dream.triage.max_ms` (per-cycle triage time budget, default 5 min — a big
+  cold corpus triages across a few cycles, with deferred files labeled "not
+  yet triaged", never silently rejected), and an opt-in per-source daily
+  synthesis cap (`dream.synthesize.max_submissions_per_source_per_day`,
+  default off; 200/day is a sane value for busy deployments). The intended
+  pairing is the shipped mid-tier synthesis default — frontier-model
+  overrides are unnecessary with triage doing the reading.
+
+### Fixed
+- A run whose submissions were all skipped (cap, already-synthesized) no
+  longer starts the 12-hour cooldown, so the skipped files retry on the next
+  cycle instead of waiting half a day.
+- Synthesis jobs stranded in a dead per-run queue by a killed cycle are
+  self-healed on the next run (cancelled and re-submitted into the live
+  queue) instead of stalling the phase for the full 35-minute wait.
+- `gbrain dream retriage --help` (and richer `gbrain dream --help`) now
+  print real usage instead of the generic one-line stub, with no brain
+  configured.
+
+To take advantage of v0.46.2.0: upgrade and run `gbrain dream` as usual —
+existing verdicts are re-scored automatically on the next cycle (cheap,
+utility-tier). If you have a queued synthesis backlog, run
+`gbrain dream retriage --dry-run` to preview, then
+`gbrain dream retriage --reconcile-queue` to drain it for pennies. Tune
+`dream.triage.threshold` freely; re-gating is free.
+
+## [0.46.1.0] - 2026-08-15
+
+**A stuck job can no longer take down your whole worker.** Field reports from
+a production deployment ([#5](https://github.com/garrytan-agents/gbrain/issues/5),
+[#6](https://github.com/garrytan-agents/gbrain/issues/6)) showed two
+compounding failure modes: a handler that ignored its abort signal could only
+be "force-evicted" (abandoned but still running, still holding connections),
+and abandoned probe/renewal queries starved the connection pool until the
+worker killed itself with a misleading "DB unreachable" — while the database
+sat at a fraction of capacity. This release fixes the starvation class and
+adds real per-job blast-radius control.
+
+### Added
+- **`gbrain jobs work --job-isolation process`** (also
+  `gbrain jobs supervisor --job-isolation process`, env
+  `GBRAIN_JOB_ISOLATION`): each claimed job runs in its own child process.
+  A stuck handler is group-SIGKILLed for real instead of abandoned, a crash
+  or memory blowup takes one job instead of all N, and the OS reclaims every
+  leaked resource when the child dies. The worker keeps claiming, renewing,
+  and recording; handler-error semantics (unrecoverable → dead, rate-lease →
+  no attempt burned, backoff otherwise) are preserved across the boundary.
+  Worker shutdown gives children the drain window to finish and report — a
+  routine deploy never burns a job attempt. Recommended for long-running
+  LLM-bound handlers; see the new section in `docs/guides/minions-deployment.md`.
+- **Health-probe verdicts that name the failing layer.** When the worker's DB
+  probe fails, it now disambiguates via the direct session lane and says
+  `pool_starved` ("server IS reachable; the fault is in the
+  transaction-pooler path") or `server_unreachable` — instead of the blanket
+  "DB unreachable" that historically sent operators debugging database
+  capacity while the real fault was client-side. A startup warning also makes
+  single-pool mode (direct-lane kill switch) loud instead of silent, and
+  `docs/guides/queue-operations-runbook.md` gains a verdict-interpretation
+  table.
+- `GBRAIN_POOL_MAX_LIFETIME_S`: explicit client-pool connection max-lifetime
+  knob (0 disables; default stays the per-connection 30–60min jitter).
+
+### Fixed
+- **Timed-out DB probes and lock renewals are now cancelled, not abandoned.**
+  Every place that raced a query against a timer (health probe, minion lock
+  renewal, cycle-drain renewal, submit-time queue probes, DB-lock refresh)
+  previously let the losing query keep running on a checked-out connection —
+  under pool exhaustion each abandoned racer held a slot and made the
+  exhaustion worse, starving the lock heartbeat first. All five sites now
+  abort the query via its cancellation signal so the slot is released.
+- Long-running maintenance holds (index rebuilds, non-transactional
+  migrations, backfill write batches) now reserve from the direct session
+  lane instead of pinning the worker's shared pool — capped so reserved
+  holds always leave a direct-lane slot for the claim/renewal heartbeats,
+  and falling back to the previous behavior when the direct lane is
+  unavailable.
+
+Full operational detail: `docs/guides/minions-deployment.md` (isolation
+sizing: connections, memory, spawn cost) and
+`docs/guides/queue-operations-runbook.md` (probe verdicts).
+
+## [0.46.0.0] - 2026-08-14
+
+**Your other agents' sessions become brain knowledge.** Until now only Claude
+Code sessions flowed into the brain automatically; every Codex rollout,
+OpenClaw session, and Hermes conversation on your disk — often years of
+decisions — was invisible. `gbrain transcripts ingest` imports them all as
+readable conversation pages with provenance back to the exact session file,
+and the facts pipeline makes them answer "what did I decide about X, in
+whichever agent I said it" as one query. Consumer chat exports (ChatGPT and
+Claude.ai `conversations.json`) import through the same door.
+
+- **One command, six formats.** `gbrain transcripts ingest <path-or-glob>`
+  auto-detects Claude Code JSONL, Codex rollouts, OpenClaw sessions, the
+  Hermes SQLite store (read from a lock-safe copy), and extracted
+  ChatGPT/Claude.ai exports. No arguments shows what it WOULD import across
+  your harness directories; `--all` imports the discovered set;
+  `gbrain transcripts status` shows the found-vs-imported gap per harness.
+- **Safe by default.** Secrets are redacted before anything is written
+  (bodies, titles, speaker labels, and session metadata; plus your
+  `harvest-private-patterns.txt` rules), message content that mimics
+  conversation formatting cannot forge speakers or timestamps, and imports
+  are a readable text-turn archive by design — tool payloads and thinking
+  blocks never land in pages (one-line placeholders mark where they
+  happened). Embedding is off by default for bulk backfills
+  (opt in with the embed flag, or run the embed backfill later).
+- **Free to re-run.** Unchanged sessions skip on content hash; long sessions
+  split into searchable parts that reconcile themselves when a session
+  shrinks; interrupted runs converge on the next pass, healing any half-done
+  writes. `--since last` resumes from the previous complete run and never
+  advances past files it could not fully read.
+- **Facts on demand.** `--facts` extracts through the shipped
+  conversation-facts pipeline under a budget cap; imported pages also flow
+  into the existing scheduled backfill when that cycle phase is enabled.
+
+### Added
+- `gbrain transcripts ingest` and `gbrain transcripts status` subcommands
+  (engine-free `--help`), with discovery mode, `--all`, `--dry-run`,
+  `--format`, `--limit`, `--since <iso|last>`, `--source-id`, `--facts`,
+  `--max-cost-usd`, `--embed`, `--json`, `--quiet`.
+- Transcript-adapter seam at `src/core/transcripts/` (session-granular
+  contract with per-file diagnostics and drift alarms; dated spec targets per
+  host format) and adapters for Codex, OpenClaw, Hermes, ChatGPT export, and
+  Claude.ai export; the shipped Claude Code parser gains an additive
+  timestamp-preserving mode, regression-pinned for the hook lane.
+- Batch `slugs` selector on the conversation-facts extraction core (one
+  invocation per import run; an empty list is a no-op, never a full-corpus
+  walk).
+- Write-back fidelity e2e through the raw adapter path (gold-extractor
+  seam), pinning cross-harness continuity in one source.
+
+### Changed
+- `skills/conversation-archive` now routes the covered formats to the native
+  importer and states the native-vs-manual privacy delta.
+- The fixture-privacy gate also scans the new transcript fixture corpus.
+
+### Fixed
+- PGLite `putRawData` now detects a missing page like the Postgres engine
+  (integrity failures abort instead of silently no-opping).
+
+### To take advantage of v0.46.0.0
+Upgrade, then run `gbrain transcripts ingest` with no arguments to see every
+importable session log on the machine, and `gbrain transcripts ingest --all`
+to import them. Unzip consumer exports first and pass the extracted
+`conversations.json`. On PGLite, stop `gbrain serve` for the import (the
+single-writer lock error names the PID if you forget). Run
+`gbrain transcripts status` any time to see what's still waiting.
+## [0.45.20.0] - 2026-08-14
+
+**Grok Build joins the supported-client roster.** xAI's `grok` CLI can now wire a gbrain brain in one command, and — like Hermes before it — the install path is proven against the real binary, not written from docs: every asserted flag, config shape, and exit-code quirk was observed against a pinned Grok Build install, recorded in a machine-checked pin document, and exercised by a real-binary e2e door that CI can run.
+
+### Added
+
+- **Grok Build install support.** `grok mcp add gbrain -- gbrain serve --surface verbs` wires the seven-verb memory surface into xAI's coding agent; [docs/mcp/GROK.md](docs/mcp/GROK.md) carries the full guide — registration, direct TOML config, the trust-gated vendor-config fallback (an existing Claude Code registration may already work), verification via `grok mcp doctor` (the honest probe: the add itself is lazy and always exits 0), headless auth, model pinning, auto-update pinning for reproducible environments, cron pairing, and troubleshooting (including the colliding community `grok` binary and where Grok actually discovers skills). `INSTALL_FOR_AGENTS.md` gains the matching "If you are Grok Build" block; the guide is honest that this is the brain-only install — the `gbrain bootstrap` personal-agent path doesn't support Grok yet.
+- **`gbrain claw-test --live --agent grok`.** Grok is the third registered agent runner, so guide-following friction runs and `gbrain friction diff --base <hermes-run> --compare <grok-run>` work out of the box. The runner records a version preamble in every transcript (a mis-bound community binary is diagnosable after the fact) and warns loudly when the operator's `~/.claude.json` registers gbrain — Grok reads vendor MCP configs for trusted folders, a contamination channel no other supported agent has.
+- **A real-binary "door" e2e for Grok** (`test/e2e/install-real-grok.serial.test.ts`), split-gated so the free tier needs no API key: version pin, the documented registration shape end-to-end, the seven-verb handshake proven keyless, a vendor-fallback provenance guard, and the direct-TOML surface all run with just the binary; the paid recall smoke (a per-run nonce fact, web search disabled) additionally needs `XAI_API_KEY`. A label-gated `grok-door` CI job provisions the pinned npm package (wrapper AND per-platform payload integrities pre-checked against the pin doc), banks the keyless coverage before any secret is required, and refuses green on a silently-skipped paid tier.
+- **`docs/mcp/GROK-CLI-PIN.md`** — the observed-behavior pin (config schema verbatim, lazy-add semantics, honest doctor discriminator, keyless TUI sign-in behavior, volatile-path inventory, supported-version policy) with machine-readable stamps enforced against the CI workflow by a new `check-grok-pin` verify guard, which fails closed if the pin doc ever disappears out from under the door job.
+- **A `grok-install` DX scenario** (`scripts/dx-explore.ts`) drives the REAL interactive Grok TUI through the brain-only install under a PTY, with a sign-in-wall early-stop so keyless runs record the friction in seconds instead of pasting into a login screen for the full wall clock.
+
+### Changed
+
+- **Agent runners share their detection/env plumbing.** The byte-identical binary-resolution and env-filtering bodies moved out of the per-agent runners into `agent-runner.ts` (`detectBinary`/`filterAllowlistEnv`), shrinking every future runner; binary resolution never passes through a shell anymore. The live-lane Grok runner forwards only Grok's own credentials — the operator's Anthropic/OpenAI keys never reach a third-party binary.
+- **PTY transcripts are structurally redacted at every write site.** Provider-key values are replaced in every artifact — including the live screen mirror that outlives interrupted runs — with a hard-failing independent check behind the redaction; a secret split across output bursts can no longer be reassembled from the frame log. `--keyless` now genuinely drops provider keys in all install scenarios, the leak check never touches files that predate the run, and the PTY hot loops strip bounded windows instead of the whole buffer (repaint-heavy TUIs were making every poll quadratic).
+- **The hermes-door CI job got the same hardening sweep:** checkout token persistence off, and the door's full test output is preserved as evidence even for the failure class that previously left no trace.
+
+To take advantage of v0.45.20.0: nothing changes for existing installs — this release adds a client, it doesn't modify brain behavior. Grok Build users: follow [docs/mcp/GROK.md](docs/mcp/GROK.md) (two commands: register, then `grok mcp doctor gbrain` to verify the seven-verb handshake). Maintainers enabling the paid CI lane: create the `XAI_API_KEY` repo secret, then land the follow-up that adds the schedule and canary legs.
+## [0.45.19.0] - 2026-08-15
+
+**The interactive `gbrain init` pickers are now tested on a real terminal — and the repo carries one PTY layer instead of two.** The first thing every new user touches (the embedding provider picker and the search-mode picker) previously had no true-TTY coverage; the comments that claimed otherwise pointed at a harness nothing ever called.
+
+### Added
+- A real-PTY test for the interactive init flow (`test/init-picker-pty.serial.test.ts`). It drives both pickers under a true pseudo-terminal, proves typed input actually lands (non-default selections plus bounded response times, so dead input can never pass through the pickers' silent defaults), covers the Ctrl-D/EOF fallback, and runs in the required serial CI lane. Fully hermetic: temp-root home, no provider keys visible, child process reaped even on failed assertions.
+
+### Removed
+- The unused second PTY harness (`test/helpers/cli-pty-runner.ts` plus its self-test, ~657 lines). Its spawn path never gained a caller across ~20 minor versions. The real-terminal layer is consolidated on `test/helpers/tty-harness.ts` (Bun's built-in `terminal:` spawn — no native modules).
+
+### Fixed
+- Three test-file comments that claimed interactive-picker coverage existed where it didn't — two deferred to each other in a circle, one described a piped-stdin test as PTY-based. All three now point at the real coverage.
+
+### Changed
+- `docs/TESTING.md` gains a four-tier decision table for TTY and interactive-CLI testing (injected `isTTY` → piped stdin → real-PTY serial test → DX-exploration instrument), including the rule that CI-required interactive tests live in the serial lane. `docs/architecture/KEY_FILES.md` now describes the surviving harness accurately, and related project docs and the stale shard-weight entry were trued up to match.
+
+## [0.45.18.0] - 2026-08-15
+
+**Today's agent spend now reads correctly at every hour, in every timezone.** The admin spend endpoint computed "today" against a naive timestamp that each database session reinterpreted in its own timezone — on any non-UTC session (a PGLite brain following the host clock, a timezone-configured Postgres role), the day boundary shifted by the offset and every evening's spend silently underreported as 0. The boundary is now a UTC instant, independent of session timezone, pinned by a regression test that exercises sessions 12 hours either side of UTC at any wall-clock hour.
+
+The same class also made the new test-suite snapshot fixture time-of-day flaky: the snapshot bakes the build machine's timezone into the restored cluster, so snapshot-restored engines ran sessions in the builder's zone while cold-init engines followed the running process. Restored engines now re-pin their session to the runtime zone (existing tarballs heal without a rebuild), the snapshot builder pins UTC so tarballs are deterministic across hosts, and a parity test asserts cold and snapshot engines agree on their UTC offset.

+- `/admin/api/agents/spend`: `spent_cents_today` no longer underreports on non-UTC sessions (UTC-instant day boundary).
+- Snapshot-restored PGLite engines behave identically to cold-init engines regardless of the machine that built the tarball.

 ## Capabilities
 
-**Hybrid search.** Vector (HNSW on pgvector) + BM25 keyword + reciprocal-rank fusion + source-tier boost + intent-aware query rewriting. Three named search modes (`conservative`, `balanced`, `tokenmax`) bundle the cost/quality knobs into a single config key. Live cost/recall comparisons in [`docs/eval/SEARCH_MODE_METHODOLOGY.md`](docs/eval/SEARCH_MODE_METHODOLOGY.md). The install picker default-applies `tokenmax` (it recommends `conservative` for Haiku-class subagent tiers or keyless setups); a brain with `search.mode` unset resolves to `balanced` at query time. The ZeroEntropy reranker is on in `balanced` and `tokenmax`, off in `conservative`. Per-query graph signals notice when a top result is a hub for THAT query (adjacency boost), is corroborated across team brains (cross-source boost), or is being crowded out by weak chunks from a chatty session (session demote). Run `gbrain search "<query>" --explain` to see per-stage attribution: base score, every boost that fired, what it multiplied. `gbrain doctor` ships a `graph_signals_coverage` check; `gbrain search stats` shows fire counts and failure breakdowns. Vector retrieval pools the best chunk per page, so a page surfaces on its strongest evidence instead of losing to a neighbor on one weak chunk. Queries that match a page's title phrase or a declared free-text alias (`gbrain reindex --aliases` backfills existing pages) get boosted to the page they name. Every result carries an `evidence` tag (why it matched) and a `create_safety` hint (`exists` / `probable` / `unknown`) so an agent decides whether a page already exists instead of guessing from a raw score. `gbrain search diagnose "<query>" --target <slug>` traces which retrieval layer surfaces (or misses) a page.

 **Self-wiring knowledge graph.** Every `put_page` extracts entity refs from markdown/wikilinks/typed-link syntax and writes edges with zero LLM calls. Typed edges (`attended`, `works_at`, `invested_in`, `founded`, `advises`, `mentions`, …). Multi-hop traversal via `gbrain graph-query`. The graph is what produces the +31.4 P@5 lift over vector-only RAG. **Obsidian-style vaults:** bare `[[note-name]]` wikilinks that point across folders — you wrote `[[struktura]]` but the page lives at `projects/struktura.md` — resolve by basename once you opt in with `gbrain config set link_resolution.global_basename true`. Off by default; `gbrain doctor` tells you how many edges you'd gain before you flip it. See [migrating an Obsidian vault](INSTALL_FOR_AGENTS.md#step-45-wire-the-knowledge-graph).

+## v0.47 SEPTEMBER REMOVAL — ZeroEntropy (filed v0.46.3.0; TARGET: ship 2026-09-04..2026-09-08)
+
+ZeroEntropy's hosted API dies 2026-09-04. v0.46.3.0 deprecated it (split-default:
+new installs → voyage; legacy runtime fallbacks stay ZE; detect-and-notify
+migration). The removal wave deletes the provider and performs the hard cutover.
+Staged-deletion discipline (ship replacements → migrate call sites → update tests
+→ THEN delete; see the skills/_brain-filing-rules precedent below):
+
+- [ ] **P1 — HARD CUTOVER: retire the legacy configless runtime fallbacks.**
+  `DEFAULT_EMBEDDING_MODEL`/`DEFAULT_EMBEDDING_DIMENSIONS` (src/core/ai/defaults.ts)
+  stop resolving to `zeroentropyai:*`; unmigrated configless brains get a HARD,
+  actionable error naming `gbrain migrate embeddings --to voyage:voyage-4 --dim 1024`.
+  Also flip `DEFAULT_RERANKER_MODEL` (gateway.ts) + the three mode-bundle
+  `reranker_model` values (mode.ts:298,348,403) to `voyage:rerank-2.5` — one-time
+  knobs-hash query-cache miss for ALL modes incl. conservative (reranker_model is
+  hashed unconditionally; document in that release's CHANGELOG). Verify the schema
+  generators' legacy-constant consumers (pglite-schema, postgres-engine,
+  embedding-column.ts registry fallback) get a deliberate post-ZE story.
+- [ ] **P1 — PREREQ before recipe deletion: move gateway.ts's `'/models/rerank'`
+  default path onto explicit per-recipe `path` fields.** llama-server-reranker and
+  dashscope-rerank may ride the implicit ZE-shaped fallback — audit + pin with tests
+  FIRST or their rerank calls 404 the day the fallback goes.
+- [ ] **P1 — Delete the provider surface.** `src/core/ai/recipes/zeroentropyai.ts` +
+  registry entries (recipes/index.ts); `zeroEntropyCompatFetch`,
+  `MAX_ZEROENTROPY_RESPONSE_BYTES`, `ZeroEntropyResponseTooLargeError` + the
+  fetch-ternary arm (gateway.ts); ZE sets in dims.ts; `ze-switch.ts` +
+  `retrieval-upgrade-planner.ts` + `retrieval-upgrade-prompt.ts` (~1200 lines) +
+  cli.ts dispatch/CLI_ONLY/flag-registry rows; `checkZeEmbeddingHealth` in doctor
+  (`provider_sunset` STAYS and goes generic — read `recipe.sunset` instead of the
+  hardcoded ZE constants); pricing rows LAST (budget-tracker rerank metering reads
+  them for historical audit rows). NOTE: test/ai/zeroentropy-compat-fetch.test.ts
+  greps gateway.ts SOURCE TEXT — delete the test with the code, in the same commit.
+- [ ] **P1 — Self-host continuity decision.** The v0.46.3 playbook's zero-re-embed
+  path keeps the `zeroentropyai:zembed-1` id behind a base-URL override to a
+  ZE-wire-compatible endpoint. Recipe deletion breaks it. Decide: keep a minimal
+  local-only recipe shell (no picker/auto-pick, no hosted default URL), ship a
+  signature-migration tool (rewrite pages.embedding_signature provider ids without
+  re-embedding), or explicitly end the promise with a loud migration note. The
+  playbook (skills/migrations/v0.46.3.0.md) links here — honor it.
+- [ ] **P2 — Tests + CI.** Delete the 8 ZE-dedicated test files
+  (zeroentropy-recipe, zeroentropy-compat-fetch, dims-zeroentropy,
+  e2e/zeroentropy-live, ze-switch-cli, ze-switch-env-override, doctor-ze-checks,
+  provider-sunset-doctor.serial gets REWRITTEN generic not deleted) + update ~40
+  coupled files; drop the zeroentropy-live job + ZEROENTROPY_API_KEY secret from
+  .github/workflows/e2e.yml:168,179 (already date-skip-gated since v0.46.3);
+  scripts/test-weights.json rows.
+- [ ] **P2 — Config + docs.** `zeroentropy_api_key` config key: keep
+  parseable-but-warned (removing it would make old config.json files fail to
+  load); delete docs/ai-providers/zeroentropy.md + its scripts/llms-config.ts
+  entry (+ `bun run build:llms`); v0.46.3 migration stays registered and must
+  degrade gracefully once the recipe is gone (notice-only — verify its copy).
+- [ ] **P2 — Custom-column off-ramp (not removal-gated, but September makes it
+  urgent for affected users).** Write-side custom-column migration
+  (`gbrain embed --column X --model Y`, embedding-column.ts:60-62 v2 deferral) so
+  ZE-backed `embedding_columns` entries get an executable migration instead of
+  drop-and-re-embed guidance.
+- [ ] **P3 — Optional `cohere-rerank` recipe.** Cohere rerank-4.0-pro is the
+  strongest surviving hosted reranker (Agentset ELO 1629, behind only the dying
+  zerank-2) for users who want max rerank quality on a dedicated key. Wire shape
+  differs from the ZE/voyage dialect — needs its own `top_param`/response mapping
+  audit. Filed from the v0.46.3 CEO review (deferred cherry-pick).
+
+## Issues #5+#6 follow-ups (pool starvation + process isolation; plan: ~/.claude/plans/system-instruction-you-are-working-witty-moore.md)
+
+- [ ] **P1-companion — nested-checkout audit + dev-mode detection.** **What:**
+  `transaction()` callers that invoke parent-engine methods (or module helpers
+  taking `engine` not `tx`) take a SECOND read-pool slot while holding the tx
+  slot — e.g. the `operations.ts` advisory-lock loop around `tx.addLink`. Under
+  a saturated pool this is a client-side self-deadlock class. Audit call sites;
+  add a dev-mode warning (e.g. a tx-depth counter consulted by `runUnsafe`).
+  **Why:** the #6 incident's exact 240s-idle sessions were never reproduced
+  under a debugger; this is the strongest remaining candidate — the shipped
+  wave mitigates the starvation class but does not close this path. **Effort:**
+  M. **Priority:** P1-companion.
+- [ ] **P2 — per-handler isolation policy.** **What:** a per-handler-name set
+  (e.g. long-running LLM-bound handlers isolate, sub-second `lint`/`backlinks`
+  stay inline) instead of the all-or-nothing `--job-isolation process`.
+  **Why:** spawn cost (~0.3–1s) is noise for 644s subagent jobs, meaningful
+  for sub-second handlers; one worker should be able to mix. **Context:**
+  `worker.ts` executeJob's `isolated` gate is the seam. **Effort:** M.
+  **Priority:** P2.
+- [ ] **P2 — per-child --max-rss caps.** **What:** RSS watchdog for isolation
+  children (the worker-level watchdog covers the worker only in process mode;
+  a startup note ships today). **Context:** child-job-runner.ts owns the child
+  lifecycle; a poll of the child's RSS + group-kill on breach mirrors the
+  worker watchdog. **Effort:** M. **Priority:** P2.
+- [ ] **P2 — jobs-side connection-budget clamp for isolated workers.** **What:**
+  warn/clamp concurrency when `concurrency × (child pool + 1) + parent pools`

+  `sync-concurrency.ts:clampWorkersForConnectionBudget`). **Why:** isolation
+  multiplies pooler CLIENT connections (~73 at concurrency 15); today the
+  budget lives only in docs math. **Effort:** S. **Priority:** P2.

+  S. **Priority:** P3.
+- [ ] **P3 — runLockRenewalTick adoption in the cycle drain.** **What:**
+  `synthesize.ts` now uses the minimal `runDrainRenewalTick` (per-call signal +
+  guard); adopting the full tick would add the audit channel + bounded
+  reconnect. **Effort:** S. **Priority:** P3.
+- [ ] **P3 — streaming child progress.** **What:** isolation children report
+  progress via their own token-fenced DB writes today (identical to inline);
+  an IPC stream would only add parent-side visibility (e.g. lifecycle events
+  in `jobs watch`). **Effort:** M. **Priority:** P3.
+- [ ] **P3 — connection-audit release events + plain-idle visibility.**
+  **What:** `logConnectionEvent` never emits `release`, so the JSONL cannot
+  answer "who holds a slot"; and `getIdleBlockers` filters
+  `state='idle in transaction'` only — the #6 incident's plain-`idle` sessions
+  were invisible to it. **Effort:** M. **Priority:** P3.
+- [ ] **P3 — doctor connection_routing check.** **What:** wire
+  `ConnectionManager.describeMode()` + `healthCheck()` (both currently
+  zero-caller outside tests) into a doctor check naming the routing mode,
+  kill-switch state, and per-pool probe latency. Comments in four files
+  already reference this check as if it existed. **Effort:** S.
+  **Priority:** P3.
+- [ ] **P3 — isolation test-gap follow-ups (pre-landing review).** **What:**
+  (a) spawned-CLI negative tests for `jobs run-child` bootstrap guards (PGLite
+  → exit 13; missing job-id/env → exit 13) and for `jobs work` with
+  isolation on + an unresolvable child CLI (fail-fast exit 1) — both need a
+  real engine bootstrap so they live in the e2e lane; (b) a behavioral (not
+  structural) test driving `withRefreshingLock` with a hung injected
+  `handle.refresh` (signal aborted at timeout, no overlapping ticks); (c) a
+  force-evict-skip test for isolation mode (needs the 30s evict window made
+  injectable); (d) operator-flow message tests (verdict-tailored FATAL text,
+  single-pool startup banner). **Why:** the ship coverage audit scored the
+  wave 82% — these are the surviving gaps. **Effort:** M. **Priority:** P3.
+- [ ] **P3 — raceWithAbortTimeout shared helper.** **What:** the
+  "Promise.race a query vs a setTimeout that aborts an AbortController,
+  clearTimeout in finally" pattern now exists at five sites (db-probe
+  withDeadline, synthesize runDrainRenewalTick, lock-renewal-tick callAbort,
+  db-lock tickAbort, supervisor probeAbort), each re-deriving the same
+  invariants. Extract one helper and adopt it. **Effort:** S. **Priority:** P3.
+- [ ] **P3 — lazy handler resolution in run-child.** **What:** every isolation
+  child runs full registerBuiltinHandlers (incl. plugin discovery) to resolve
+  ONE handler; the job name is known from the row — a resolve-by-name path
+  would skip discovery for builtins. Matters only if isolation is ever used
+  for short jobs (documented as not the target). **Effort:** S. **Priority:** P3.
+- [ ] **P3 — full checkout instrumentation via a Sql proxy.** **What:** the
+  CheckoutGauge covers raw/direct/reserved/tx seams only; tagged-template
+  traffic (most engine load) is untracked. A proxy around the postgres.js Sql
+  callable could count real checkouts — investigate cost/fragility before
+  building. **Why:** would turn the probe's "tracked subset" caveat into full
+  coverage. **Effort:** M. **Priority:** P3.

+**Priority:** P2
+
+**What:** Unit shards exclude `test/e2e/*` (`scripts/test-shard.sh`), and `.github/workflows/e2e.yml` runs only explicitly named files (a handful across its jobs — e.g. `test/e2e/mechanical.test.ts`, `test/e2e/mcp.test.ts`, the jsonb-parity pair); there is no glob. Every other `test/e2e/*.test.ts` — including PGLite-only files that need no `DATABASE_URL`, like `init-fresh-pglite.test.ts` — executes only when someone runs `bun run test:e2e` by hand. Decide per file: wire into a required workflow, re-home PGLite-only files to the serial lane (the pattern `test/init-picker-pty.serial.test.ts` uses), or explicitly document them as manual-only.

+**Priority:** P2
+

Fix: `readLineSafe` (src/commands/init.ts) should latch EOF — once stdin has ended, later calls return their default immediately instead of waiting out the timer. Regression test: extend the EOF case in `test/init-picker-pty.serial.test.ts` to run init to completion and assert exit well under the fallback window (the case currently closes early on purpose to keep the 60s stall out of required CI — see the comment there).

+
+Scoped OUT of the cathedral-4 PR by the CEO review's cherry-pick ceremony and the
+eng review — each carries a named design, none is a bug. Context: the import lane
+(adapters at `src/core/transcripts/`, session-atomic pipeline, embed-OFF default)
+covers DEAD logs; go-forward capture beyond Claude Code is deliberately absent.
+
+- [ ] **OpenClaw go-forward capture.** Blocked upstream: the OpenClaw PluginApi exposes only `registerContextEngine` — no end-of-turn/agent-end capability. When the host grows one, the plugin (`src/openclaw-context-engine.ts`) subscribes and emits the session into the corpus lane (`~/.gbrain/transcripts/corpus` sidecar protocol) the way `gbrain hook session-end` does for Claude Code; the openclaw session PARSER already ships. Consent must ride a capture line like the bootstrap harness `--no-capture` model. Priority: P2.
+- [ ] **Codex go-forward capture (notify sweeper).** `docs/designs/AGENT_BOOTSTRAP_PLAN.md` FF2 names the design (notify sweeper over `~/.codex/sessions`); the rollout parser now ships in `src/core/transcripts/codex.ts`, so the sweeper is pure wiring: on codex notify, run `gbrain transcripts ingest <rollout> --quiet`. Needs the same consent posture as capture. Priority: P2.
+- [ ] **Scheduled re-import cycle phase.** `transcripts ingest --since last --all` as an opt-in cycle phase so dead-log import self-refreshes. REQUIRES its own consent-line design first: reading harness dirs on a schedule is capture-adjacent (the "Autonomous transcript watchers" decision above rules the spirit); the clean-scan watermark + status gap table already make manual re-runs cheap. Priority: P3.
+- [ ] **PII auto-detection redaction pass for imports.** The native lane redacts secrets (secret-scan) + user patterns (`harvest-private-patterns.txt`, emails included) and counts imperatives; broad PII detection (names, phones, addresses) is its own subsystem — the conversation-archive skill keeps the human scrub step for sensitive corpora meanwhile. Priority: P2.
+- [ ] **More harness adapters: Cursor / Gemini CLI / Copilot CLI.** Leaf modules on the `TranscriptAdapter` seam (~1h each with an agent): dated SPEC_TARGET + scrubbed fixture + drift alarm, per the shipped six. Formats unverified locally — verify a real sample first (the hermes gate pattern). Priority: P3.
+- [ ] **ChatGPT/Claude.ai export zip unwrapping.** v1 requires the EXTRACTED `conversations.json` ("unzip first" is documented + error-hinted). Add zip handling without a heavy dependency (Bun has no built-in zip; evaluate a minimal vendored inflate or shelling to `unzip` with confinement). Priority: P3.
+- [ ] **BrainBench raw-format fixture schema (sibling repo).** The in-repo pin (`test/e2e/transcripts-writeback-fidelity.test.ts`) grades raw files through the adapters with the gold extractor, but the BrainBench corpus schema (gbrain-evals) still rejects unknown keys and its corpus hash doesn't cover raw sidecars. Needs: versioned raw-fixture sidecar type + loader + hash coverage + baseline re-cut in gbrain-evals, then a `write_back_fidelity_raw` suite row here. Priority: P2.
+- [ ] **Hermes SPEC_TARGET verification against a populated store.** The schema came from the installed hermes-agent v0.20.0 source (`SCHEMA_SQL`), but no populated `state.db` existed on the dev machine — the fixture is synthetic-by-declaration. Verify against a real store after some Hermes sessions accrue, then flip `status: 'provisional'` → `'verified'` and pin the `active`/`compacted` semantics the adapter currently ignores. Priority: P3.

+  label leg, default-on dispatch, and a latest-version CANARY matrix leg
+  (`continue-on-error`, schedule-scoped, own timeout) so the pinned lane stays
+  deterministic while the canary tracks what users run. Same session: run the

+  and carries no key-shaped material or non-example emails.
+- [x] **P3 — opencode-door npm view-vs-install TOCTOU.** DONE (adversarial-review
+  fix wave): the door job's install step is now pack-verify-install — `npm pack
+  <pkg>@<ver> --json` downloads the artifact and reports the integrity of the
+  BYTES written; both the wrapper and the platform payload are asserted against
+  their pins before `npm install -g ./opencode-ai-*.tgz` installs from the
+  verified local tarball (no fresh registry resolve of the name; the payload's
+  install-time fetch is npm-validated against the same byte-confirmed packument).
+  Verified locally on darwin-arm64 (wrapper integrity == pin; `--ignore-scripts`
+  breaks opencode's postinstall binary placement, so it is deliberately absent).
+- [x] **P3 — `opencode mcp list` probe spawns project-config servers.** DONE
+  (adversarial-review fix wave): the user-scope probe spawns from a fresh EMPTY

+## opencode adversarial-review fix-wave follow-ups (filed at fix time)
+
+- [ ] **P2 — per-harness MCP-scope consent key.** An interview MCP_SCOPE answer
+  recorded for Claude Code (where 'project' is the privacy-SAFE default)
+  currently authorizes opencode's INVERTED-risk scopes without fresh
+  confirmation ('project' on opencode = committed file that auto-spawns on
+  every collaborator machine, no trust gate), and an ABSENT answer defaults
+  opencode to user-global exposure (any repo on the machine reaches the
+  brain). Design a harness-specific consent confirm — either per-harness
+  answer keys (MCP_SCOPE_OPENCODE) or a one-time "your recorded scope means
+  something riskier here — confirm" gate on the opencode lane. Relates to the
+  agent-bootstrap A8 consent-semantics TODO. Effort: M.
+- [ ] **P3 — opencodeEntryKind remote ownership: normalize the url compare.**
+  Ownership uses exact string equality on the entry url vs the receipt/expect
+  url — trailing-slash and host-case variants misclassify in BOTH directions
+  (ours read as foreign → orphaned entry; a variant-url foreign endpoint
+  never matches, fine, but the asymmetry is accidental). Consider URL
+  normalization (scheme/host case-fold, trailing-slash) plus an
+  Authorization-shape check before comparing. Effort: S.
+- [ ] **P2 — claw-test --live runners inherit real HOME/XDG.** The grok /
+  hermes / opencode --live runners run against the operator's real
+  HOME/XDG config surface and only WARN on a pre-existing global gbrain
+  entry; a scripted run can mutate or exercise the operator's live wiring.
+  Consider a fail-closed flag (refuse when a global gbrain registration
+  exists unless --allow-live-config) or hermetic-by-default across the
+  runner family. Effort: M.
+- [ ] **P3 — fixed-name `.bak` parity: codex-toml.ts + hooks.ts writers.**
+  opencode-json.ts now takes UNIQUE `.bak-<hex>` backups per operation
+  (overlapping runs can't clobber each other's snapshot; harness restores
+  from the returned path and unlinks on success). The codex TOML writer and
+  the hooks settings writers still use fixed-name backups with the same
+  theoretical overlap window — port the unique-backup pattern (and the
+  restore-guard compare) for parity. Effort: S/M.
+## Dream triage cascade follow-ups (#4152, filed at implementation)
+
+- [ ] **P2 — Incremental submit-drain + deadline threading in synthesize
+  fan-out.** What: restructure the fan-out to submit bounded batches and
+  drain each before submitting more, stopping against the parent job's
+  `deadlineAtMs`. Why: today the phase bulk-submits every accepted child
+  then drains sequentially inside `autopilot-cycle`'s 30-min wall clock
+  (`handler-timeouts.ts:44`); a timeout mid-drain strands the remainder in
+  the run's private queue (the C1 self-heal + retriage conversion now
+  recover them, but not creating strands beats recovering them). Blocked
+  by: `runCycle` does not thread deadline/abort into phases (verified
+  absent at the synthesize call site, cycle.ts ~2030). Context: outside
+  voice C2 on the #4152 eng review; the triage `max_ms` budget bounds the
+  cheap half, this bounds the expensive half. Effort: M/L.
+- [ ] **P2 — Scheduled reject sample-audit with spend-posture
+  integration.** What: automate `dream retriage --audit-rejects N` on a
+  cadence (weekly cron or post-cycle sampling) writing disagreement-rate
+  telemetry, gated by `spend.posture`. Why: the threshold is an
+  intuition-set 0.5 until real false-negative data exists; the cascade
+  literature is unanimous that unaudited gates drift (eng-review search
+  check). The manual flag ships with #4152; this files the loop that runs
+  without an operator remembering. Depends on: a few weeks of production
+  score distributions. Effort: M.
+- [ ] **P3 — Borderline-band routing (0.30–0.49 → mid-tier model or batch
+  digest).** What: a second lane where near-threshold files get a cheaper
+  treatment instead of the binary keep/drop. Why: the issue marked it
+  optional; it adds a third model lane + a second threshold pair, which
+  should be tuned from `details.triage` score distributions rather than
+  guessed. Blocked by: production calibration data (see the audit TODO
+  above). Effort: M.
+- [ ] **P3 — Source×corpus multiplier: per-source corpus mapping or
+  explicit fan-out consent.** What: `dream.synthesize.session_corpus_dir`
+  is GLOBAL config while synth idempotency keys are SOURCE-namespaced, so
+  N registered sources each re-fan the same corpus (a live deployment saw
+  3 × ~1,250 jobs/day of the same files). Triage verdicts are
+  source-agnostic (judged once) and the cascade cuts each source's fanout
+  by the pass rate, but total synthesis is still N× the corpus. Why
+  deferred: pages land per-source, so per-source synthesis may be intended
+  semantics for some operators — needs its own issue + design (per-source
+  corpus config keys vs an explicit multi-source consent flag). Diagnostic:
+  `dream retriage --reconcile-queue --json` reports `queue.by_source`.
+  Context: outside voice C3 argued root-cause-first; scoped out twice
+  during the #4152 review. Comment on #4152 after ship. Effort: M.
+- [ ] **P3 — Dream triage perf follow-ups (from the #4152 ship review).**
+  What: (a) batch the per-file `getDreamVerdict` PK probes in `runTriagePass`
+  into one prefetch (unnest join on (file_path, content_hash)) and reuse it
+  for retriage's spend-estimate loop (currently 2×N sequential roundtrips on
+  the operator sweep); (b) a partial index for `countRecentSynthSubmissions`
+  (`(created_at) WHERE name='subagent' AND idempotency_key LIKE
+  'dream:synth-v2:%'`) so the opt-in daily cap's count is index-served on
+  busy brains; (c) a shared `seedTriageVerdict` test helper to collapse the
+  five hand-rolled triage-v1 seed blocks. Why: all flagged by the ship
+  review's performance/maintainability specialists; none block — cache
+  probes are ~0.1% of adjacent LLM latency and the cap is default-off.
+  Effort: M.
+- [ ] **P3 — Per-file single-flight for triage cache misses.** What:
+  concurrent passes (retriage while a cycle runs) can double-judge the same
+  uncached file (~1¢/file, last-write-wins converges — benign but untidy);
+  a per-(file,hash) advisory claim would dedupe. Why deferred: real locks
+  are heavy machinery for a benign-cost race; the retriage help documents
+  the behavior. Context: outside-voice CX5 on the #4152 ship review.
+  Effort: M.

+| Question | Tool | Example |
+|---|---|---|
+| Does the TTY/non-TTY branch logic pick right? | Inject `isTTY` into the pure function — no subprocess | `test/init-provider-picker.test.ts`, `test/jobs-watch-mode.test.ts` |
+| Does the real CLI behave right when stdin is NOT a terminal? | Spawn the CLI with piped/ignored stdio | `test/cli-stdin-hang.test.ts` (fast loop); `test/e2e/init-fresh-pglite.test.ts` (manual `test:e2e` lane — see the TODOS e2e CI-lane entry) |
+| Does the real CLI render menus and read typed input under a REAL terminal? | `launchTty` from `test/helpers/tty-harness.ts` in a `*.serial.test.ts` file | `test/init-picker-pty.serial.test.ts` |
+| How does the install FEEL (stalls, copy, silence windows)? | `scripts/dx-explore.ts` — instrument, not a test; nothing asserts | transcripts under `.context/dx-runs/` (see `docs/guides/bootstrap.md`) |
+
+Real-PTY test rules: put the file in the serial lane (`*.serial.test.ts` — that
+lane runs in required CI; a new `test/e2e/*` file does NOT, since unit shards
+exclude the directory and the e2e workflow runs only explicitly named files,
+no glob);
+assert NON-default picker values (bare Enter and each prompt's 60s
+`readLineSafe` timeout both resolve to the default, so a defaults-asserting
+test passes with dead input); always `await session.close()` in a `finally`

+# claude-cli — the `claude-cli` recipe (routes chat/toolLoop through the local `claude` CLI)
+
+This page documents the `claude-cli` recipe as it already ships (added in
+v0.42.66.0, PR #3310 — see `CHANGELOG.md`) — it is not proposing new
+behavior. The implementation lives at `src/core/ai/recipes/claude-cli.ts`
+and `src/core/ai/providers/claude-cli-language-model.ts`; neither
+`README.md` nor `docs/` mentioned this recipe before this page, so the only
+description of how it behaves lived in those source comments.
+
+`claude-cli` routes `gateway.chat()` and `gateway.toolLoop()` through the
+`claude` CLI binary as a subprocess (`claude --print ...`) instead of through
+the Anthropic SDK. It sits alongside the existing `anthropic` recipe as a
+second `Recipe` entry with the same touchpoint shape; which one a given
+model string resolves to is a per-call choice: `anthropic:claude-sonnet-5`
+resolves to the `native-anthropic` implementation (SDK + `ANTHROPIC_API_KEY`),
+`claude-cli:claude-sonnet-5` resolves to `ClaudeCliLanguageModel` (subprocess,
+CLI-managed auth).
+
+**Chat-only — no embedding.** `gateway.embed()` throws immediately for
+`claude-cli` models (`claude-cli has no embedding model. Use openai or google
+for embeddings.`). Claude has no first-party embedding model regardless of
+transport; pair this recipe with `openai`, `google`, or `voyage` for
+embeddings the same way the `anthropic` recipe's docs already recommend.
+
+## Setup
+
+1. Install Claude Code (the `claude` CLI) and run `claude` once to log in.
+   If the binary is not on `PATH`, point the gateway at it explicitly:
+
+   ```bash
+   export GBRAIN_CLAUDE_CLI_BIN=/path/to/claude
+   ```
+
+2. Point a model tier (or any per-call model string) at `claude-cli:`:
+
+   ```bash
+   gbrain config set models.tier.subagent claude-cli:claude-sonnet-5
+   ```
+
+   Any of the models the recipe declares work the same way:
+   `claude-cli:claude-opus-5`, `claude-cli:claude-haiku-4-5-20251001`, etc.
+   Short aliases (`claude-cli:sonnet`, `claude-cli:haiku`, `claude-cli:opus`)
+   resolve the same way the `anthropic` recipe's aliases do.
+
+The recipe declares `auth_env: { required: [] }`, and neither the recipe
+nor the adapter code reads or passes any API-key-shaped config value to the
+subprocess — whatever the `claude` binary does for its own auth (see below)
+is between it and its own login state, not something gbrain's config layer
+participates in. There is also no `provider_base_urls` entry for this
+recipe — it has no base URL, only a subprocess binary path
+(`GBRAIN_CLAUDE_CLI_BIN`).
+
+## What actually happens on a call
+
+Each `doGenerate` call spawns `claude --print --output-format json --model
+<id> --disable-slash-commands --tools '' --strict-mcp-config` as a
+subprocess, with `cwd` set to a per-process directory under the OS tmpdir
+(`join(tmpdir(), 'gbrain-claude-cli-cwd-' + process.pid)`, created via
+`mkdirSync(..., { recursive: true })` if missing — code doesn't otherwise
+touch or inspect its contents), and pipes the rendered prompt to it on
+stdin:
+
+- `--tools ''` disables every built-in tool (Bash/Read/WebSearch/…) — the
+  subprocess must behave like a raw LLM, not a full agent.
+- `--strict-mcp-config` skips loading the user's MCP servers. Without it,
+  every call would boot the user's configured MCP servers — including
+  gbrain's own MCP, which would recurse and contend for the PGLite
+  single-writer lock.
+- The subprocess env is a copy of gbrain's own process env with exactly
+  three keys deleted before spawn: `ANTHROPIC_API_KEY`, `ANTHROPIC_AUTH_TOKEN`,
+  `ANTHROPIC_BASE_URL`. Everything else in gbrain's environment is inherited
+  as-is. The recipe's source comment states the intent (stop an
+  `ANTHROPIC_API_KEY` present in gbrain's own env from being picked up by the
+  subprocess), scoped to those three variables specifically — the doc does
+  not claim this rules out every other way `claude` could end up billing
+  through a non-subscription path (e.g. other env-based auth switches the CLI
+  itself may support); that is between the installed `claude` binary and its
+  own configuration, not something this recipe's code inspects.
+- Beyond that env-scrub, auth resolution is entirely up to the installed
+  `claude` binary — the recipe does not manage or forward credentials
+  itself. Whatever `claude` is already logged in / authenticated with on
+  this machine is what it authenticates with here too (see the `claude` CLI's
+  own docs for how it stores and resolves that).
+
+`--bare` (which would skip loading the user-level `~/.claude/CLAUDE.md`
+entirely) is not among the flags passed, because it also forces
+`ANTHROPIC_API_KEY` auth (per the recipe's source comment). One effect of
+not passing it: the user-level `~/.claude/CLAUDE.md` still loads and gets
+cached tokens on every call.
+
+The adapter does not use `claude`'s own agentic tool-calling — it injects a
+fenced instruction block into the system prompt teaching the model a
+`<use_tools>[{id,name,input}, ...]</use_tools>` JSON emission format
+(`buildToolUseInstructions`), then parses that block back out of the plain
+text response into ai-sdk tool-call parts (`extractToolCalls`). This
+protocol-over-text approach is what lets `supports_subagent_loop: true`
+work through the `--print`, no-built-in-tools subprocess shape described
+above.
+
+## Constraints
+
+| Area | Behavior |
+|---|---|
+| Embedding | Not supported — `gateway.embed()` throws for `claude-cli` models. Pair with another provider for embeddings. |
+| Streaming | Not implemented. `doStream()` throws. `gateway.toolLoop()` (the main caller) is non-streaming already, so this is not a practical limitation for subagent dispatch, but any caller that expects a streaming chat surface cannot use `claude-cli`. |
+| Tool use | JSON emission via a system-prompt-injected protocol, not the CLI's native tool-call mechanism. Parallel tool calls in one turn round-trip correctly. |
+| Multimodal | Not supported over the subprocess path. File/image message parts are rendered as a `[file <mediaType>]` text stub, not sent as actual content. |
+| Prompt caching | The recipe declares `supports_prompt_cache: false`. The CLI manages its own caching internally but does not expose it through gbrain's `cache_control` control plane, so from the gateway's point of view this model does not support prompt caching. |
+| Usage / token counts | Reported `usage.input_tokens` / `usage.output_tokens` are read straight from the CLI's `--output-format json` envelope (`result.usage?.input_tokens` / `output_tokens`); gbrain does not independently count tokens for this path. |
+| Cost figures | The recipe declares `cost_per_1m_input_usd: 3.0` / `cost_per_1m_output_usd: 15.0` — the same Sonnet-class figures the `anthropic` recipe declares (`price_last_verified: 2026-06-17`) — purely so gbrain's budget ledger has a number to attribute per call. Neither the recipe nor the adapter code checks what you're actually billed; treat these as the ledger's nominal per-call number, not a verified charge. |
+| User-level CLAUDE.md | `~/.claude/CLAUDE.md` still loads on every call (see above) — only the working directory changes (see "What actually happens on a call" for exactly what that directory is and isn't). |
+
+## Known doctor caveat: cold-start subprocess vs the fixed 5s probe timeout
+
+`gbrain models doctor`'s chat reachability probe (`probeModel` in
+`src/commands/models.ts`) wraps every chat call in a fixed 5-second
+`AbortController` timeout, independent of any per-recipe timeout the recipe
+itself declares (`claude-cli` does not declare a `default_timeout_ms`).
+Spawning the `claude` binary and letting it start up is generally fast, but
+is not instantaneous — a slow first invocation (cold process cache, slow
+disk, contended machine) can outrun that 5-second window.
+
+When that happens, the probe's `AbortController` fires, the subprocess is
+killed (`child.kill('SIGTERM')`), and the adapter's abort handler rejects
+with a fixed message (`claude-cli adapter aborted`). `classifyError` in
+`src/commands/models.ts` only maps a message to `status: network` if it
+matches `/timeout|network|econn|fetch failed|enotfound/`; `claude-cli
+adapter aborted` matches none of those, so it falls through to
+`status: unknown` — the classifier's catch-all — instead of `status:
+network`, which is what a plain slow/unreachable HTTP provider would map
+to on the same probe timeout. So a `status: unknown` result on a
+`claude-cli:` model is not necessarily a broken configuration on its own;
+a cold subprocess start outrunning the fixed 5s window is one thing that
+can produce it (the same class of first-call cold-start the embedding
+reachability probe's own code comment already calls out for local
+embedders), and re-running the probe is a reasonable first thing to try.
+`status: unknown` on its own doesn't distinguish that from any other
+unclassified failure, so if a re-run keeps producing it, treat it as an
+unclassified error worth investigating rather than assuming cold-start.
+
+## Troubleshooting
+
+| Symptom | Where it comes from | Try |
+|---|---|---|
+| `claude-cli spawn failed: ...` / stdin write failure | `spawn()`'s `error` event or a failed `stdin.write` — commonly means the `claude` binary was not found on `PATH` | Install Claude Code, or set `GBRAIN_CLAUDE_CLI_BIN` to the binary's path |
+| `claude-cli exited <code>: ...` | Non-zero exit from the `claude` subprocess itself; the message is whatever the CLI wrote to stderr/stdout | Run `claude` interactively with the same model to see the underlying CLI error directly (e.g. not logged in, model unavailable) |
+| `claude-cli output not JSON: ...` | `JSON.parse(stdout)` threw (stdout wasn't valid JSON at all) | Confirm the installed `claude` CLI version still supports `--print --output-format json`; this adapter's JSON handling was verified against CLI 2.1.145 |
+| `claude-cli JSON event array had no "result" event` | stdout parsed as a JSON array (the `"verbose": true` event-stream shape in `~/.claude/settings.json`) but none of the events had `type: "result"` | Check `~/.claude/settings.json` for `"verbose": true`; the adapter tolerates the array shape but still needs a `result` event in it |
+| `gbrain models doctor` reports `chat` as `status: unknown` for a `claude-cli:` model | See "Known doctor caveat" above — `classifyError` falls through to `unknown` for the adapter's abort message | Re-run the probe; if it persists, treat it as an unclassified failure and investigate directly (e.g. run the same model via `gbrain models doctor --json` or call `claude` by hand) |
+| A call bills through the Anthropic API instead of the local session | The adapter deletes `ANTHROPIC_API_KEY` / `ANTHROPIC_AUTH_TOKEN` / `ANTHROPIC_BASE_URL` from the subprocess env — this covers gbrain's own env leaking into the call. It does not inspect any other auth/billing switch the installed `claude` CLI itself may support | If billing looks wrong, check the `claude` CLI's own auth/billing configuration on this machine, not just gbrain's env |

+The synthesize phase is a two-stage cascade: a cheap scored triage

+- `dream.triage.threshold` (default 0.5) — the gate. Scores are cached, so

+  much routine content synthesizes; lower it if real signal is being skipped.

+- `dream.triage.max_chars` (default 24000, floor 1000) — per-transcript
+  sample window (head/middle/tail) sent to the judge. Not part of cache
+  validity — after changing it, `gbrain dream retriage --force` re-judges
+  under the new sampling.
+- `dream.triage.max_tokens` (default 2048, floor 256) — judge output budget.
+- `dream.triage.concurrency` (default 4, clamped 1–16) — concurrent judge
+  calls.
+- `dream.synthesize.max_turns` (default 16) — synthesis turn budget. The
+  triage map hands the subagent pre-extracted segments, so the mid-tier
+  default model (`models.dream.synthesize`, tier `reasoning`) with a 16-turn
+  budget is the intended pairing — frontier-model overrides are unnecessary
+  and slow the queue. Completeness comes from triage coverage (every file
+  scored, minus files deferred under the `max_ms` budget below) plus
+  segment-guided prompts, not model size. If written-page counts
+  drop after upgrading, set it back to 30 and check
+  `details.synthesis.avg_turns` for cap pressure.
+- `dream.triage.max_ms` (default 5 min) — per-cycle wall-clock budget for
+  judging NEW files; a big cold corpus triages across a few cycles (cached
+  files are free). Deferred files are labeled "not yet triaged", never
+  silently rejected.
+- `dream.synthesize.max_submissions_per_source_per_day` (default 0 = off) —
+  opt-in backstop cap on synthesis jobs per source; 200/day is a sane value
+  for busy deployments.

 negative value denied without privilege, or an OS `RLIMIT_NICE` clamp). This
 is distinct from the concurrency / inflight cap and composes with it.
 
+### Per-job process isolation (`--job-isolation process`)
+
+By default all concurrency slots execute inside one worker process. A
+handler that ignores its abort signal can only be force-evicted — the
+promise is abandoned, still running, still holding connections and memory —
+and any worker exit destroys every in-flight job at once. With isolation on,
+each claimed job runs in its own child process: a stuck handler is
+group-SIGKILLed for real (group signaling under Bun falls back to POSIX
+`/bin/kill`; if that's unavailable the worker logs that isolation is
+degraded), a crash or OOM in a child takes that one job instead of all N,
+and the OS reclaims every leaked resource when the child dies:
+
+```bash
+# Recommended for long-running LLM-bound handlers (subagent):
+gbrain jobs supervisor --concurrency 4 --job-isolation process
+
+# Bare worker, or durably via env:
+GBRAIN_JOB_ISOLATION=process gbrain jobs work --concurrency 4
+```
+
+How it works: the worker keeps claim, lock renewal, and all result
+recording; the child (an internal `run-child` entrypoint of the same gbrain
+binary) re-validates the claim, runs the handler with its own small engine
+pool, and reports one atomic outcome file. Handler-error semantics are
+preserved across the boundary (unrecoverable → dead, rate-lease → no attempt
+burned, everything else → normal backoff). On worker shutdown children get
+the drain window to finish and report; a child killed before reporting is
+released with no attempt burned. If the worker dies hard, the orphaned child
+self-terminates via a parent-liveness watchdog and the stall sweeper
+requeues the job after lock expiry — the lock token fences the orphan's
+queue writes (result recording, progress, state transitions) into no-ops.
+The handler's own side effects (page writes through its engine) can still
+land until the watchdog stops the child; that window is the watchdog's
+poll + grace, not unbounded.
+
+Sizing notes:
+
+- **Connections:** each child opens its own small pools (read 3 by default,
+  override via `GBRAIN_JOB_CHILD_POOL_SIZE`; direct 1). Worked example at
+  concurrency 15: 15×(3+1) + the worker's 10+3 ≈ **73 client connections**
+  total — 55 ride the transaction-pooler lane (multiplexed, no extra server
+  backends) and 18 are lazy direct session-lane connections, each holding a
+  real server backend while open. Budget the pooler-lane count against your
+  pooler's client limit and the session-lane count against
+  `max_connections`.
+- **Memory:** `--max-rss` covers the WORKER process only in this mode
+  (handler memory lives in the children; the worker prints a note when both
+  are set). There is no per-child RSS cap yet — a runaway child is contained
+  only by host/container limits. Size host memory for concurrency × handler
+  footprint.
+- **Spawn cost:** ~0.3–1s per job (engine connect included) — noise for
+  long-running handlers, meaningful for sub-second ones (`lint`,
+  `backlinks`). Keep those inline or on a separate inline worker.
+- **Security note:** the child receives the job's lock token via env. It is
+  a *fencing* token (split-brain protection), not a secret — same-user env
+  already contains the database URL.
+- **Child CLI resolution:** the worker fail-fast validates the child CLI at
+  startup (compiled `gbrain` binary, bun-dev fallback, or the
+  `GBRAIN_JOB_CHILD_CLI` env override — the ops/test escape hatch). Three
+  consecutive child spawn/bootstrap failures self-exit the worker as
+  unhealthy (a deterministically broken child CLI) for process-manager
+  restart instead of burning attempts across the queue.

+## Reading the DB-probe verdicts (pool starved vs server unreachable)
+
+When the worker's health probe fails repeatedly, the terminal
+`[health] DB probe failed N consecutive times (verdict: ...)` line — and the
+`unhealthy` payload the supervisor sees — carries a verdict that names the
+failing LAYER (the intermediate `(N/3)` lines log only the failure detail).
+Read it before touching anything — the historical failure mode here was
+hours spent evaluating a database instance upgrade while the server sat at
+10% of max_connections.
+
+| Verdict | What it means | What to do |
+|---|---|---|
+| `pool_starved` | The read-pool probe failed but the DIRECT-lane probe succeeded — the database server is reachable; the fault is in the transaction-pooler path (client pool exhaustion or a pooler-layer fault; the probe deliberately does not distinguish the two). | Look at client-side load: long-running handler queries holding slots, `GBRAIN_POOL_SIZE` too small for the workload, or a pooler-layer incident. Do NOT resize the database. The worker exit is correct recovery — it frees every client-held slot. |
+| `server_unreachable` | Both the pooler lane and the direct lane failed. | Check connectivity/capacity first: network, DNS, the database itself. Both-lanes-failed is the evidence — credential/config errors or a saturated direct lane can also land here, so glance at the probe detail text before concluding the server is down. |
+| `unknown` | The read probe failed and no direct lane exists to disambiguate (single-pool mode: non-Supabase, kill switch active, or no derivable direct URL). | Check the startup log for the single-pool warning; consider `GBRAIN_DIRECT_DATABASE_URL` so future incidents self-diagnose. |
+
+The `gbrain-tracked in flight` counts in the message are a tracked SUBSET
+(raw/direct/reserved/transaction seams only) — most template-path queries are
+untracked, so `0 in flight` next to a `pool_starved` verdict means the
+saturation lives in that untracked traffic or at the pooler layer itself,
+not that the pool is idle. The verdict, not the counts, is the
+authoritative signal.

+`gbrain init --pglite` auto-detects which provider to use from your provider keys — env vars or the file plane (`~/.gbrain/config.json` fields like `voyage_api_key`; env wins when both are set). With `VOYAGE_API_KEY` set, you get Voyage (`voyage:voyage-4` @ 1024d). With `OPENAI_API_KEY` set, you get OpenAI. Whenever a Voyage key is present — even if a different embedding provider is picked — init also writes `search.reranker.model voyage:rerank-2.5` as explicit config (one key covers both); keyed installs without a Voyage key get `search.reranker.enabled false` written instead. If multiple provider keys are set, init fires an interactive picker (non-TTY auto-picks the Voyage default when its key is present). ZeroEntropy is deprecated and excluded from both auto-pick and the picker — explicit `--embedding-model zeroentropyai:*` still works, with a loud warning. With no provider keys at all, init continues keyless (keyword-only search) with a loud notice; recover later with `gbrain init --force --embedding-model voyage:voyage-4`. Explicit flags (`--embedding-model`, `--no-embedding`) always win over key detection.

See [the migration guide](../guides/embedding-migration.md). Self-hosting the Apache-2.0 zembed-1 weights keeps every existing vector with zero re-embed, but the endpoint must speak ZeroEntropy's wire dialect — a generic OpenAI-compatible llama-server/Ollama will NOT work without a compat proxy (details in [`docs/ai-providers/zeroentropy.md`](../ai-providers/zeroentropy.md)). `gbrain doctor` (check `provider_sunset`) flags affected brains — including ZE-backed custom embedding columns — and prints target-aware paste-ready commands (Voyage at 1024; OpenAI keep-width when the brain's actual width is valid there); accepted the risk? `gbrain config set doctor.suppress_provider_sunset true` silences it.

+- **Provisioning (CI + local): pinned npm install** — `@xai-official/grok@1.0.4`,

+  `@xai-official/grok-{darwin,linux,win32}-{arm64,x64}` optional deps at the same
+  version; the CI job pins the LINUX payload integrities too (stamps above) because
+  the wrapper's integrity covers only the wrapper tarball — the platform sub-package
+  is the binary that executes. Load-bearing assumption, stated explicitly: npm
+  version-immutability (a published version cannot be replaced on npmjs; only a new
+  version or an unpublish, both of which fail the pinned install loudly).
+- Installer path (fallback only): `https://x.ai/cli/install.sh`, sha256
+  `43d0943123edade1383a476a4f778674877acee7c1f98a00f094c4a0f7349321` (17,686 bytes).

+  string from `uname -s`/`uname -m` with a Rosetta correction on Apple Silicon.
+- Verified against macOS arm64; npm `os`/`cpu` matrix covers linux x64/arm64 for CI.

+`GROK_HOME=<tmp> HOME=<tmp> grok mcp list|add|doctor` read+write `<tmp>/config.toml`
+and do NOT touch `~/.grok`. Belt-and-suspenders (HOME + GROK_HOME both to tmp) stays
+in the door anyway. NOTE what grok writes into `$GROK_HOME` on EVERY run (tripwire
+exclusions — these are VOLATILE): `active_sessions.lock`, `active_sessions.json`,
+`bin/grok-<version>` (it copies its own binary in), `logs/unified.jsonl`,
+`docs/user-guide/*.md` (it ships its user guide into the home), `leader.sock` (a
+leader daemon socket; `--leader-socket <PATH>` overrides). The tripwire hashes ONLY
+`config.toml` + credential-class files, never the volatile set.
+
+## One-shot (`-p`)
+- `grok -p "<prompt>"` (`-p, --single`) prints the response to stdout and exits.
+- `--output-format plain|json|streaming-json|streaming-messages-json` (default plain;
+  `streaming-json` = NDJSON of native ACP session updates; `streaming-messages-json` =
+  Anthropic Messages wire format; `--include-partial-messages` adds deltas).
+- **Keyless one-shot: exit 1**, message (verbatim, both stdout and stderr):
+  `Not signed in. To authenticate without a browser, run:\n  grok login --device-code\n\nAlternatively, set the XAI_API_KEY environment variable or run `grok login` on a machine with a browser.`
+  → `hasGrokAuth()` = non-empty `XAI_API_KEY`; the TTY scenario's keyless early-stop
+  matcher is `Not signed in`.
+- Cost/toolset flags that EXIST (observed in --help): `--always-approve`,
+  `--permission-mode default|acceptEdits|auto|dontAsk|bypassPermissions|plan`,
+  `--tools <LIST>`, `--disallowed-tools <LIST>`, `--allow/--deny <RULE>`,
+  `--disable-web-search` (dedicated kill for web search + fetch — the door SMOKE uses
+  THIS, not a tools list), `--max-turns <N>`, `-m/--model`, `--reasoning-effort`
+  (alias `--effort`), `--cwd <PATH>`, `--rules`, `--prompt-file`, `--prompt-json`,
+  `--json-schema` (implies json output), `--verbatim`, `--sandbox <PROFILE>`
+  (env `GROK_SANDBOX`), `--no-memory`, `--no-plan`, `--no-subagents`.
+- There is NO auto-update CLI flag. Auto-update is config: `[cli] auto_update = true`
+  is the DEFAULT — hermetic homes MUST seed `[cli] auto_update = false`. Manual
+  updater: `grok update [--check --json --version <V> --force-reinstall --alpha]`.
+- `.envrc` gotcha: `load_envrc = true` by default — grok loads `.envrc` from the
+  working directory. Door/live spawns pin `cwd` to tmp workspaces partly for this.
+
+## Auth + model pin (non-interactive)
+- Keyless error pinned above; `grok login --device-code` exists for headless
+  interactive auth; `XAI_API_KEY` env is the documented headless path (its end-to-end
+  smoke is **pending auth** — no key was available at observation time; the door's
+  paid tier stays skip-gated until then, per plan D0).
+- `grok models` works KEYLESS (exit 0): prints `You are not authenticated.`, then
+  `Default model: grok-4.6` and the visible list (`grok-4.6 (default)`, `grok-4.5`).
+  Authenticated list may be larger; per-turn cost pins are **pending auth**.
+- Model pin mechanism: per-call `-m <model>` (authoritative in tests — immune to
+  config rewrites) and `[models] default = "<model>"` in config.toml.
+
+## `grok mcp add` — THE big observed facts
+- Shape: `grok mcp add <name> [-e KEY=value]... [-s user|project] [-t stdio|http|sse] -- <command> [args...]`
+  — everything after `--` is the server argv. **`-e/--env` is REPEATABLE, one
+  KEY=value per flag** (their docs pin this as a breaking change from earlier
+  releases: `use -e A=1 -e B=2, not --env A=1 B=2` — the hermes replace-bug class is
+  fixed upstream). Server names: letters, numbers, hyphens, underscores only.
+- **Add is LAZY: exit 0 always, NO handshake at add time, no interactive prompt**
+  (`Added stdio MCP server 'gbrain' … to user config` / `File modified:
+  $GROK_HOME/config.toml`). Adding a NONEXISTENT command also exits 0. Never assert
+  add's exit code; never treat `enabled = true` in the saved TOML as a handshake
+  proof (it is written unconditionally).
+- Scope: `-s user` (default) → `~/.grok/config.toml`; `-s project` →
+  `./.grok/config.toml` (committable; reference secrets as `${VAR}`).
+- **Bare command names resolve via the CALLER'S PATH** (verified): registering
+  `-- gbrain serve --surface verbs` with a PATH-prefixed bin dir works — doctor
+  resolved bare `gbrain` to the staged wrapper and completed the handshake. The
+  bun-run wrapper shim (`#!/bin/sh\nexec bun run <abs>/src/cli.ts "$@"`) works as the
+  staged binary (the fallback lane when a compiled binary is unavailable).
+- Startup timeout: per-server `startup_timeout_sec` (default 30) or global env
+  `GROK_MCP_STARTUP_TIMEOUT_SECS` (seconds) / `MCP_TIMEOUT` (ms, Claude-compatible).
+  The bun-run wrapper cold-transpiles slowly — the door sets 60+.
+

+]
+enabled = true

+Full schema keys (from grok's own shipped user guide, `$GROK_HOME/docs/user-guide/`):
+`command`, `args`, `env`, `enabled` (default true), `startup_timeout_sec` (default
+30), `tool_timeout_sec` (default 6000), `tool_timeouts`.
+
+## Probes — the HONEST discriminator exists
+- **`grok mcp doctor <name> --json`**: SPAWNS the server for real. Good server →
+  **exit 0** with checks `command found` / `server started` / `handshake OK`
+  (`"detail": "protocol 2025-11-25"`) / **`7 tools discovered`** (the verbs surface's
+  seven verbs, proven keyless end-to-end). Broken server (nonexistent command) →
+  **exit 1**, check `command not found`, `passed: false`, plus a `hint`. THE door's
+  hard discriminator; the T4 doctor pre-flight gates the paid loop (plan M6 resolves
+  to the honest branch).
+- Doctor `--json` also enumerates config **sources** with per-source status —
+  `~/.grok/config.toml`, `~/.claude.json`, `.mcp.json` — and each server carries a
+  `"source"` field (`"config"`, `".mcp.json"`, …): the T2b provenance assertion reads
+  this directly.
+- `grok mcp list --json` → exit 0, array of `{command, args, env, enabled, name,
+  scope}`.
+- `grok inspect` (keyless, exit 0) shows version, CWD, `Project trusted: yes/no`,
+  instructions, permissions, skills, agents — the config-discovery audit surface.

+## Vendor-config fallback — TRUST-GATED (verified)
+A project `.mcp.json` in the cwd is SEEN by doctor (source `found`, server listed
+with `source: ".mcp.json"`) but the server check reports **`folder untrusted`** and
+`mcp list` shows nothing until the folder is trusted (first-run trust flow). So:
+fresh tmp HOME + fresh cwd ⇒ vendor entries structurally cannot activate (door
+provenance guarantee), and on an operator's machine the fallback only engages for
+folders they already trusted — the live-lane warning (operator `~/.claude.json`
+carrying `mcpServers.gbrain`) still applies for trusted folders.
+
+## When the door goes red (triage)
+| Failure class | Signature | Remediation |
+|---|---|---|
+| npm pin drift | install step: version/integrity mismatch | Re-pin deliberately: bump `npm_version`+`npm_integrity` stamps here, re-run the re-observation checklist below, update workflow env pins (check-grok-pin.sh enforces the pair) |
+| installer digest drift (fallback path) | `sha256sum -c` fails on install.sh | Diff the new installer, re-pin `installer_sha256` after review |
+| version drift mid-run | `grok --version` re-check ≠ pinned | Auto-update engaged — verify `[cli] auto_update = false` seeding; re-pin if a deliberate bump |
+| blank XAI_API_KEY secret | named precondition/paid-sentinel failure | Admin adds/rotates the repo Actions secret (console.x.ai origin); keyless tier still ran |
+| invalid/expired key | bad-key preflight fails (pin its message after first authed run) | Rotate the secret; no code change |
+| tripwire fired | manifest mismatch on config/credential files only | True isolation breach — stop, inspect which file changed; volatile-path drift alone must NOT fire (bug in exclusions if it does) |
+| real door regression | doctor checks or recall assert fail with pins intact | Bisect against the pinned version; file upstream if grok-side |
+
+Re-observation checklist on a version bump: re-run the npm/installer pin captures
+(§Pin), the help-surface diff (`--help`, `mcp --help`, `mcp add --help`), and the
+mcp add → saved-TOML → doctor sequence (§add/§probes). The one-shot/auth/model
+sections only need re-observation if their assertions start failing.
+
+## Keyless TUI behavior (observed via the dx-explore PTY instrument)
+Under a real PTY with no credentials, interactive `grok` plays a Braille-
+pattern intro animation (U+2800-range glyphs) for a few seconds, then settles
+(~6s) onto a SIGN-IN screen: "Approve in your browser to finish signing in"
+plus a device code (and a ctrl+c hint). There is no unattended path past it.
+Two hazards for PTY automation, both observed: the animation frames carry
+zero word-like text (3+-letter runs) — a text-presence heuristic must count
+letter runs, not enumerate glyphs; and pasting into the sign-in screen leaves
+a persistent full-screen spinner redrawing at ~5 frames/sec, which starves
+quiet-based settling and makes full-buffer ANSI stripping the hot loop
+(strip bounded raw tails instead). Headless keyless is the clean
+`Not signed in` error above. The `grok-install` dx scenario early-stops at
+the sign-in copy (or a persistently textless screen) with the friction
+recorded — that IS the keyless measurement.
+
+## Supported-version policy
+gbrain's grok integration is verified against **Grok Build v1.0.4** (this pin). The
+canary CI leg (enabled with the secret) tracks latest and is continue-on-error; the
+pinned lane is the deterministic gate. **Pending auth** (requires `XAI_API_KEY`):
+paid one-shot smoke, authed model list + per-turn cost pins, credential-file
+inventory after login (feeds evidence exclusions + TTY secretPaths), AUTHED
+first-run TUI dialog copy (the keyless TUI + headless copies are pinned above).

+# Connect GBrain to Grok Build
+
+> This page is the MCP-registration reference for **Grok Build** — xAI's
+> official `grok` CLI (early beta, subscriber-gated; not the community
+> `superagent-ai/grok-cli`, which ships a colliding `grok` binary — see
+> Troubleshooting). For the full brain install — CLI, engine, skills, dream
+> cycle — follow [INSTALL_FOR_AGENTS.md](../../INSTALL_FOR_AGENTS.md) first;
+> this page wires the finished brain into Grok Build over stdio MCP.
+> The `gbrain bootstrap` persistent-personal-agent path is **not yet
+> supported for Grok** (Claude Code and Codex only today) — brain-only
+> install is what this page delivers.
+
+Grok Build spawns `gbrain serve` as a local stdio subprocess. No server, no
+tunnel, no token needed. Works with both PGLite and Supabase engines.
+
+## Register (recommended)
+
+```bash
+grok mcp add gbrain -e "GBRAIN_HOME=$HOME" -- gbrain serve --surface verbs
+```
+
+`--surface verbs` exposes the seven-verb memory protocol (`recall`,
+`remember`, `entity`, `synthesize`, `forget`, `context_pack`, `delta` —
+[MEMORY_VERBS v1](../protocol/MEMORY_VERBS_v1.md)) instead of the full
+100+-op catalog — the recommended starting surface for coding agents.
+Three facts about `grok mcp add`, all observed:
+
+- **The env flag is repeatable, one `KEY=value` per flag** (`-e A=1 -e B=2`).
+  Server argv goes after `--`.
+- **Registration is lazy.** The add writes config and exits 0 without
+  connecting — even for a nonexistent command. Verify with `grok mcp doctor`
+  (below), never with the add's exit code.
+- **Scope:** the default writes to `~/.grok/config.toml`; add `-s project`
+  to write a committable `./.grok/config.toml` instead (reference secrets as
+  `${VAR}` in project scope — values are stored verbatim).
+
+## Direct config (equally supported)
+
+The add command writes an `[mcp_servers.gbrain]` block into
+`~/.grok/config.toml` (or `./.grok/config.toml` with project scope; the
+`GROK_HOME` env var relocates the user config dir). You can write it
+yourself instead:
+
+```toml
+[mcp_servers.gbrain]
+command = "gbrain"
+args = ["serve", "--surface", "verbs"]
+startup_timeout_sec = 60
+enabled = true
+
+[mcp_servers.gbrain.env]
+GBRAIN_HOME = "/home/alice-example"
+```
+
+`startup_timeout_sec` defaults to 30; raise it (or export
+`GROK_MCP_STARTUP_TIMEOUT_SECS`) if gbrain runs from source via `bun run`,
+which cold-transpiles on first spawn. To remove gbrain, delete the block (or
+set `enabled = false` to disable without losing the config).
+
+## Zero-config vendor fallback
+
+Grok Build also reads MCP registrations from `~/.claude.json`, `.cursor/mcp.json`,
+and a project `.mcp.json` — at lower priority than its own config, and **only
+for folders you have trusted** in Grok (fresh folders report
+`folder untrusted` until you accept the trust prompt). If you already
+registered gbrain for Claude Code, Grok may pick it up with zero
+configuration. `grok mcp doctor --json` reports every source it consulted
+and which one each server came from — check the `source` field to see which
+config won before assuming the native one did.
+
+## Verify
+
+```bash
+grok mcp list --json        # entry: {"name":"gbrain","enabled":true,...}
+grok mcp doctor gbrain      # THE real probe: spawns the server
+```
+
+`grok mcp doctor gbrain` performs the actual handshake — expect the checks
+`command found`, `server started`, `handshake OK`, and `7 tools discovered`
+(the seven verbs), exit 0. A broken registration exits 1 with a failing
+check and a hint. Then one real round-trip:
+
+```bash
+grok -p "use the gbrain recall tool to answer: what did I import most recently?"
+```
+
+`grok -p` (single-turn headless) prints the final answer on stdout.
+
+## Headless auth + model pin
+
+For cron jobs, CI, or any non-TTY run:
+
+- **Auth:** export `XAI_API_KEY` (from console.x.ai). Keyless headless runs
+  exit 1 with `Not signed in`; `grok login --device-code` is the
+  interactive-terminal alternative, `grok login` the browser one.
+- **Model pin:** pass `-m <model>` per call, or set it in config:
+
+  ```toml
+  [models]
+  default = "grok-4.5"
+  ```
+
+- **Updates:** Grok self-updates by default. For pinned/reproducible
+  environments, seed:
+
+  ```toml
+  [cli]
+  auto_update = false
+  ```
+
+## Pair with cron
+
+Grok Build has no built-in cron; schedule headless one-shots with your
+system scheduler:
+
+```bash
+# crontab: brain maintenance every 4 hours
+0 */4 * * * XAI_API_KEY=... grok -p "Run gbrain sync and report anything unusual" --output-format plain
+```
+
+See [docs/guides/cron-schedule.md](../guides/cron-schedule.md) for the full
+brain maintenance protocol (sync, embed, dream cycle).
+
+## Troubleshooting
+
+- **Wrong `grok` on PATH** — the community `superagent-ai/grok-cli` also
+  installs a `grok` binary. The official CLI answers `grok --version` with
+  `grok X.Y.Z (buildhash)`; anything else is the other tool. Install the
+  official one via `npm install -g @xai-official/grok` or
+  `curl -fsSL https://x.ai/cli/install.sh | bash`.
+- **grok ≠ groq ≠ ngrok** — Grok Build (xAI, `XAI_API_KEY`) is not Groq
+  (the inference provider, `GROQ_API_KEY`) and not ngrok (tunnels). A
+  mis-set key produces auth errors against the wrong service.
+- **`Not signed in` (exit 1)** — no auth in a headless run. Export
+  `XAI_API_KEY` or run `grok login --device-code`.
+- **Doctor says `folder untrusted`** — the registration came from a vendor
+  config (`.mcp.json` / `~/.claude.json`) in a folder Grok hasn't been told
+  to trust. Trust the folder in an interactive session, or register
+  natively with `grok mcp add`.
+- **Doctor times out on `server started`** — raise `startup_timeout_sec`
+  (or `GROK_MCP_STARTUP_TIMEOUT_SECS=90`) if gbrain runs via `bun run`.
+- **Skills note:** `gbrain skillpack scaffold` writes `skills/<name>/SKILL.md`
+  into your workspace, which Grok does **not** auto-discover as Grok skills
+  (it reads `.grok/skills`, `~/.grok/skills`, `~/.agents/skills`, plugins).
+  gbrain's skills still work as reference documents the agent reads;
+  `grok inspect` shows what Grok actually discovered.
+- **`grok inspect`** — the config-discovery audit: version, cwd trust,
+  instructions, permissions, skills, agents, MCP sources.
+
+---
+
+Verified against **Grok Build v1.0.4** (early beta — expect churn; the pin
+is enforced in CI). Dev-facing observed-behavior notes (exact flag
+semantics, exit-code caveats, config schema, CI pin values) live in

+# opencode CLI pin — observed behavior notes (v1.18.18)
+
+Dev-facing companion to [OPENCODE.md](OPENCODE.md): every fact below was OBSERVED
+against a real hermetic install (2026-08-15, macOS arm64), not researched from docs.
+The claw-test OpencodeRunner, the install door e2e, and the heavy-tests
+opencode-door CI job assert exactly these shapes — when opencode releases change
+them, update this file, the workflow pins, and the affected assertions together
+(`scripts/check-opencode-pin.sh` in `bun run verify` enforces the workflow-side
+match). Where an observation CONTRADICTS opencode's docs, the observation wins and
+the contradiction is called out inline.
+
+Naming note: **opencode** (SST, opencode.ai, npm `opencode-ai`) is not **OpenClaw**
+(the agent platform gbrain ships a runner for) and not the original `opencode` CLI
+that was renamed Crush — see Troubleshooting in OPENCODE.md for the binary-name
+collision.

+
+## Pin
+- **opencode v1.18.18**, `opencode --version` output shape: bare `1.18.18` —
+  version only, NO binary-name prefix, NO build hash (unlike grok's
+  `grok 1.0.4 (hash)`). The door's T1 shape assert is `/^\d+\.\d+\.\d+$/` on the
+  trimmed output; SST identity is discriminated by the `mcp`+`debug` subcommands
+  existing (`opencode debug paths` exits 0 and prints the path table below —
+  the renamed-to-Crush ancestor and other claimants have neither).
+- **Provisioning (CI + local): pinned npm, pack-verify-install** —
+  `opencode-ai@1.18.18`, registry integrity `sha512-J+5HFq…`. The CI job
+  `npm pack`s the wrapper AND the runner's platform payload first (pack
+  reports the integrity of the bytes it actually downloaded — closing the
+  view-then-install TOCTOU), asserts both against the stamps above, then
+  installs FROM the verified local wrapper tarball; the install-time platform
+  sub-package fetch is validated by npm against the same packument integrity
+  the pack step just byte-confirmed. The wrapper fans out to per-platform
+  payloads (`opencode-{darwin,linux,windows}-{arm64,x64}[-baseline|-musl]`) as
+  optionalDependencies at the same version; the LINUX payload integrities are
+  pinned separately because the wrapper's integrity covers only the wrapper
+  tarball. Darwin arm64 payload observed at
+  `sha512-VkG+bz8u8Xqg9NzPK+2/71nEd4DKKlo2NLZurQ1eLAzDnmb1CMYZif/o6Shl8YFuTuYU/30k6yufl4Zr0Ij64g==`
+  (informational — the CI runners are linux). Same npm version-immutability
+  assumption as the grok pin, stated explicitly.
+- A curl installer (`https://opencode.ai/install`) exists but is NOT the pinned
+  lane; npm is.
+
+## Pin-refresh cadence (this CLI ships near-continuously)
+opencode releases far faster than grok (patch releases near-daily). The pinned
+lane is the deterministic gate; the **canary leg** in `opencode-door` (schedule-
+scoped, `continue-on-error`, installs `opencode-ai@latest`) exists to surface
+drift BEFORE it strands the pin. Policy: when the canary leg reds or the pin is
+>6 weeks old, run the re-observation checklist (bottom) against latest, bump the
+stamps + workflow env pins together, and note behavior deltas in this file.
+Do not chase every patch release; refresh on canary signal or the 6-week clock.
+
+## Path seams — XDG honored; OPENCODE_CONFIG* env vars are INERT (verified)
+`opencode debug paths` is the authoritative dump. Observed under
+`HOME=<tmp> XDG_CONFIG_HOME=<tmp>/.config XDG_DATA_HOME=<tmp>/.local/share`:
+
+```
+config   <XDG_CONFIG_HOME>/opencode          (opencode.json + opencode.jsonc)
+data     <XDG_DATA_HOME>/opencode            (auth.json, opencode.db*, log/, repos/)
+state    <tmp>/.local/state/opencode         (locks/)
+cache    <tmp>/.cache/opencode               (bin/)
+tmp      /tmp/opencode
+```
+
+- **HOME + XDG_CONFIG_HOME/XDG_DATA_HOME redirection works fully on macOS**
+  (nothing was written outside the hermetic home across the whole observation
+  run). The door uses HOME + both XDG vars, belt-and-suspenders.
+- **DOCS-CONTRADICTION: `OPENCODE_CONFIG`, `OPENCODE_CONFIG_DIR`, and
+  `OPENCODE_CONFIG_CONTENT` had NO observable effect on config resolution in
+  1.18.18** — probes registered via each were absent from `mcp list`, while the
+  XDG-resolved global config was still read. gbrain's path helpers therefore
+  resolve via XDG only and deliberately do NOT honor `OPENCODE_CONFIG*`;
+  re-observe on version bump (if a future release activates them, the helpers
+  and this section change together). Hermetic child envs still DELETE all three
+  (defense against a future release activating them).
+- Volatile paths (tripwire exclusions): `opencode.db`, `opencode.db-shm`,
+  `opencode.db-wal`, `log/`, `repos/` under data; `locks/` under state; `bin/`
+  under cache. The tripwire hashes only `opencode.json(c)` + `auth.json`.
+- Vendor quirk: opencode writes a `.gitignore` (node_modules, package.json, …)
+  into the CONFIG dir on first touch.
+
+## Config format — JSONC everywhere, both filenames merge (verified)
+- `~/.config/opencode/opencode.jsonc` AND `~/.config/opencode/opencode.json`
+  are BOTH read when both exist (servers from each appeared simultaneously in
+  `mcp list`) — merge, not first-wins. opencode's own `mcp add` writes the
+  `.jsonc` name.
+- **Comments parse in `.json`-named files too** (a `// comment` inside project
+  `opencode.json` did not break resolution). JSONC is the effective grammar for
+  every config file regardless of extension → gbrain's writer treats all
+  opencode configs as JSONC (jsonc-parser surgical edits; comments survive).
+- Project config: `opencode.json` in the project root is read (lookup traverses
+  up); a project-scope entry appears alongside global entries.
+- Unknown keys inside an `mcp.<name>` entry are TOLERATED in 1.18.18 (an
+  `_gbrain` probe key neither errored nor hid the server). gbrain still does
+  NOT write marker keys — ownership is judged by structural fingerprint — so a
+  future strict-schema flip cannot brick a user's opencode.
+- `opencode debug config` prints the resolved merge (rendering has a doubled-
+  line quirk; treat it as a debug view, not a parse surface).
+
+## `opencode mcp add` — observed facts
+- Shape: `opencode mcp add <name> [--env KEY=VALUE]... -- <command> [args...]`
+  (local) or `opencode mcp add <name> --url <URL> [--header KEY=VALUE]...`
+  (remote). The `-- command` form is real but UNDOCUMENTED in `--help` (the
+  help lists only `--url/--env/--header`; the error copy for a bare add says
+  `Provide either --url <url> or a command after --`).
+- **Always writes the GLOBAL `opencode.jsonc`** — even when a project
+  `opencode.json` with an `mcp` table exists in the cwd. There is NO scope
+  flag. Project-scope registration requires writing the file directly (gbrain's
+  writer does).
+- **Add is lazy**: exit 0, no spawn, no prompt — for unreachable URLs and
+  nonexistent commands alike. Never treat add's exit code as a handshake.
+- **Rewrites preserve comments and foreign keys** (a seeded `// comment` and a
+  `theme` key survived a subsequent add) — opencode uses a JSONC-preserving
+  editor internally; gbrain's writer matches that bar.
+- `--header` values are stored verbatim, including `{env:VAR}` interpolation
+  syntax (`Authorization=Bearer {env:GBRAIN_REMOTE_TOKEN}` round-trips).
+
+## Saved config schema (verbatim, from real adds)
+```jsonc
+{
+  "$schema": "https://opencode.ai/config.json",
+  "mcp": {
+    "gbrain": {
+      "type": "local",
+      "command": ["gbrain", "serve", "--surface", "verbs"],
+      "environment": { "GBRAIN_SOURCE": "workspace", "GBRAIN_HOME": "/tmp/<brain-home>" }
+    },
+    "gbrain-remote": {
+      "type": "remote",
+      "url": "https://brain.example/mcp",
+      "headers": { "Authorization": "Bearer {env:GBRAIN_REMOTE_TOKEN}" }
+    }
+  }
+}
+```
+`enabled` is optional (absent = enabled). `oauth` was not written by the CLI and
+is omitted by gbrain's writer (no OAuth interference with bearer headers was
+observed). Local commands: an absolute `command[0]` works; PATH-resolved bare
+`gbrain` resolves via the SPAWNING process's PATH (the door verifies the staged
+bin-dir prepend).
+
+## Probes — `mcp list` is the honest discriminator; `mcp debug` is NOT
+- **`opencode mcp list` SPAWNS every configured local server and connects every
+  remote one**, then prints per-server status: `✓ <name> connected` or
+  `✗ <name> failed` with a reason line (`Executable not found in $PATH:
+  "gbrain"`, `SSE error: …`). THE door's keyless handshake proof. Caveats:
+  **exit code is 0 even when servers fail** (parse the text, assert
+  `✓ gbrain connected`), output is clack-style UI with ANSI codes, and there is
+  no `--json`.
+- **`mcp list` is also a code-execution surface**: it spawned a PROJECT-defined
+  `type:local` command from a fresh checkout with NO prompt and NO trust gate
+  (verified with a touch-file probe). Two consequences: (1) gbrain's
+  bootstrap default scope for opencode is USER-GLOBAL — a committed project
+  entry would auto-spawn on every collaborator's machine; (2) any gbrain-run
+  probe uses `--pure` (kills external plugin autoload) + `OPENCODE_DISABLE_AUTOUPDATE=1`.
+- `opencode mcp debug <name>` is OAUTH debugging only — on a local server it
+  prints `MCP server <name> is not a remote server` and exits 0. Not a
+  discriminator.
+- No tool-count line exists in `mcp list` (grok's `7 tools discovered` has no
+  analog); tool discovery is proven by the SMOKE turn's `tool_use` events
+  instead.
+
+## One-shot (`opencode run`) — KEYLESS WORKS (anonymous free tier)
+- `opencode run "<msg>"` prints the ANSWER TEXT ALONE on stdout; the session
+  banner (`> build · <model>`) and UI go to stderr. Exit 0 on success; exit 1
+  with a structured JSON error (`"ref": "err_…"`) on failure (e.g. bogus
+  model).
+- **Keyless runs WORK**: with zero credentials and no auth.json, `run` answers
+  via opencode's anonymous free tier (default model observed:
+  `opencode/big-pickle`; `opencode models` lists 8 keyless `opencode/*` models,
+  most `-free` suffixed; `opencode stats` reports $0.00). There is no
+  `Not signed in` wall in headless run mode.
+- **MCP tools fire in keyless run mode WITHOUT `--auto`** (verified: the free
+  model called `gbrain_recall` and returned a seeded per-run nonce with
+  `--auto` absent). `--auto` exists (`auto-approve permissions that are not
+  explicitly denied (dangerous!)`) but the door does not need or use it.
+- MCP tool naming: `<server>_<tool>` (observed `gbrain_recall`).
+- `--format json` emits NDJSON events, every event
+  `{type, timestamp, sessionID, part}`; types observed: `step_start`,
+  `tool_use`, `text`, `step_finish`. Tool events carry
+  `part: {type:"tool", tool:"gbrain_recall", callID, state:{status:"completed",
+  input:{…}, output:"<stringified JSON>"}}` — `parseOpencodeJsonl` pins this.
+- Model flag: `-m/--model <provider/model>` (`opencode/big-pickle` confirmed;
+  paid ids follow models.dev convention — see Pending auth).
+- Keyless SMOKE end-to-end (proven 2026-08-15): pinned opencode + free model +
+  real `gbrain serve --surface verbs` (7 verbs banner) recalled a per-run nonce
+  through MCP with zero credentials, keyless PGLite brain.
+
+## Environment — detectHarness + child-env facts (verified)
+- Inside `run`'s bash tool, opencode sets **`OPENCODE=1`** and `OPENCODE_PID`
+  in child processes → `gbrain bootstrap`'s `detectHarness()` probes
+  `OPENCODE`.

+# Connect GBrain to opencode
+
+> This page is the MCP-registration reference for **opencode** — the SST
+> terminal coding agent (opencode.ai, npm `opencode-ai`; not OpenClaw, and not
+> the original `opencode` CLI that was renamed Crush — see Troubleshooting).
+> For the full brain install — CLI, engine, skills, dream cycle — follow
+> [INSTALL_FOR_AGENTS.md](../../INSTALL_FOR_AGENTS.md) first; this page wires
+> the finished brain into opencode over stdio MCP. opencode is a
+> **bootstrap-supported harness**: `gbrain bootstrap hooks --harness opencode`
+> registers the brain for you (and `gbrain connect --agent opencode` handles
+> remote brains — see below) — the commands on this page are the standalone
+> manual recipe. Bootstrap's own registration additionally pins the workspace
+> source (`GBRAIN_SOURCE`) and the full op surface, so the two are not
+> byte-identical.
+
+opencode spawns `gbrain serve` as a local stdio subprocess. No server, no
+tunnel, no token needed. Works with both PGLite and Supabase engines — and
+because opencode natively reads `AGENTS.md`, a gbrain workspace's rendered
+brain contract loads with zero extra configuration.
+
+## Register (recommended)
+
+```bash
+opencode mcp add gbrain --env GBRAIN_HOME=$HOME -- gbrain serve --surface verbs
+```
+
+`--surface verbs` exposes the seven-verb memory protocol (`recall`,
+`remember`, `entity`, `synthesize`, `forget`, `context_pack`, `delta` —
+[MEMORY_VERBS v1](../protocol/MEMORY_VERBS_v1.md)) instead of the full
+100+-op catalog — the recommended starting surface for coding agents.
+Three facts about `opencode mcp add`, all observed:
+
+- **The local-command form is `-- <command> [args...]` after the flags** —
+  it's real but missing from `--help` (which shows only `--url/--env/--header`).
+  `--env` is repeatable, one `KEY=VALUE` per flag.
+- **Registration is lazy.** The add writes config and exits 0 without
+  connecting — even for a nonexistent command. Verify with `opencode mcp list`
+  (below), never with the add's exit code.
+- **It always writes the USER-GLOBAL config**
+  (`~/.config/opencode/opencode.jsonc`) — there is no scope flag. For a
+  project-scoped entry, write the project `opencode.json` directly (next
+  section) — but read the sharing warning first.
+
+## Direct config (equally supported)
+
+Global (`~/.config/opencode/opencode.jsonc`) or project (`opencode.json` in
+the repo root — opencode's lookup traverses up to the git root):
+
+```jsonc
+{
+  "$schema": "https://opencode.ai/config.json",
+  "mcp": {
+    "gbrain": {
+      "type": "local",
+      "command": ["gbrain", "serve", "--surface", "verbs"],
+      "environment": { "GBRAIN_HOME": "/home/alice-example" },
+      "enabled": true
+    }
+  }
+}
+```
+
+Comments are fine — opencode parses JSONC in both `.json` and `.jsonc` files,
+and both filenames are read (merged) when both exist. To remove gbrain,
+delete the entry, or set `"enabled": false` to disable without losing it.
+
+**Sharing warning for project config:** opencode spawns project-defined local
+MCP servers with **no trust prompt** — a committed `opencode.json` carrying a
+gbrain entry executes on every collaborator's machine. Teammates without
+gbrain get a failing spawn each session; teammates WITH gbrain attach their
+own `host` brain to your repo's context. Prefer the user-global config (the
+gbrain bootstrap default); if you do commit a project entry, use the
+PATH-resolved `"gbrain"` command form (never an absolute path) and tell
+collaborators `"enabled": false` is the opt-out.
+
+## Verify
+
+```bash
+opencode mcp list        # the real probe: SPAWNS the server
+```
+
+`opencode mcp list` performs the actual spawn + handshake for every
+configured server — expect `✓ gbrain connected`. A broken registration shows
+`✗ gbrain failed` with the reason (e.g. `Executable not found in $PATH`).
+Because it spawns everything — including any project `opencode.json` entries
+in your cwd, with no trust prompt — run it from a directory you trust
+(gbrain's own bootstrap verification probe runs from an empty temp directory
+for exactly this reason, and skips the live probe entirely for project-scoped
+registrations).
+Two caveats: the exit code is 0 even when servers fail (read the output, not
+`$?`), and `opencode mcp debug` is OAuth-only diagnostics — it is NOT a
+handshake probe for local servers. Then one real round-trip:
+
+```bash
+opencode run "use the gbrain recall tool to answer: what did I import most recently?"
+```
+
+`opencode run` (headless one-shot) prints the final answer alone on stdout
+(UI goes to stderr). MCP tools work in run mode without any permission flags.
+
+## Remote brains (`gbrain connect`)
+
+For a brain served over HTTP on another machine:
+
+```bash
+gbrain connect https://your-host/mcp --token gbrain_xxx --agent opencode [--install]
+```
+
+Without `--install` it prints the config block to add; with `--install` it
+writes the entry directly into the user-global config (no opencode binary
+required — the JSONC write IS the registration) and smoke-tests the token.
+Either way the config stores only the `{env:GBRAIN_REMOTE_TOKEN}`
+interpolation — opencode resolves the env var at read time, so the token
+never lands in the file. Export `GBRAIN_REMOTE_TOKEN` in your shell profile.
+`--force` replaces a gbrain-managed entry whose endpoint moved (a rotated
+serve); an entry gbrain didn't write is never replaced — pick another
+`--name`. (Framework-spawned opencode inherits no shell profile;
+`gbrain bootstrap harness --harness opencode` covers that case with an
+inline-bearer entry written 0600.)
+
+## Auth + model pin
+
+- **Keyless works.** opencode ships an anonymous free tier (default model
+  `opencode/big-pickle` at observation time) — headless runs and MCP tool
+  calls work with zero credentials. For paid providers, export the provider
+  key (e.g. `ANTHROPIC_API_KEY`) or run `opencode auth login` (credentials
+  land in `~/.local/share/opencode/auth.json`).
+- **Model pin:** pass `-m <provider/model>` per call, or set `"model"` in the
+  config. `opencode models` lists what your credentials can reach.
+- **Updates:** opencode self-updates by default. For pinned/reproducible
+  environments, set BOTH `"autoupdate": false` in config AND
+  `OPENCODE_DISABLE_AUTOUPDATE=1` in the environment.
+
+## Pair with cron
+
+opencode has no built-in cron; schedule headless one-shots with your system
+scheduler:
+
+```bash
+# crontab: brain maintenance every 4 hours
+0 */4 * * * opencode run "Run gbrain sync and report anything unusual"
+```
+
+See [docs/guides/cron-schedule.md](../guides/cron-schedule.md) for the full
+brain maintenance protocol (sync, embed, dream cycle).
+
+## Troubleshooting
+
+- **Wrong `opencode` on PATH** — the name has prior claimants (the original
+  `opencode` project was renamed Crush). The SST CLI answers
+  `opencode --version` with a bare semver (`1.18.18`) and has `opencode mcp`
+  + `opencode debug paths` subcommands. Install it via
+  `npm install -g opencode-ai` or `curl -fsSL https://opencode.ai/install | bash`.
+- **opencode ≠ OpenClaw** — opencode (opencode.ai / SST) is the terminal
+  agent this page covers; OpenClaw is the agent platform with its own gbrain
+  runner and docs ([OPENCLAW.md](OPENCLAW.md)).
+- **`✗ gbrain failed — Executable not found in $PATH`** — the registered
+  command was the bare `"gbrain"` name and opencode's PATH doesn't carry it.
+  Use the absolute binary path in the user-global config, or fix PATH.
+- **Registered but nothing changed mid-session** — opencode reads config at
+  session start; restart opencode (or start a new session) after registering.
+- **`OPENCODE_CONFIG` seems ignored** — observed inert in v1.18.18: only
+  `HOME`/`XDG_CONFIG_HOME` move the config location. Don't rely on it.
+- **Which config won?** — `opencode debug config` prints the resolved merge;
+  `opencode debug paths` prints every directory opencode uses.
+- **Rules files** — opencode loads the project `AGENTS.md` (a sibling
+  `CLAUDE.md` is NOT double-loaded; AGENTS.md wins). gbrain's rendered
+  workspace contract rides this natively.
+
+---
+
+Verified against **opencode v1.18.18** (fast-moving project — the pin is
+enforced in CI, with a latest-version canary leg watching for drift).

-**Hybrid search.** Vector (HNSW on pgvector) + BM25 keyword + reciprocal-rank fusion + source-tier boost + intent-aware query rewriting. Three named search modes (`conservative`, `balanced`, `tokenmax`) bundle the cost/quality knobs into a single config key. Live cost/recall comparisons in [`docs/eval/SEARCH_MODE_METHODOLOGY.md`](docs/eval/SEARCH_MODE_METHODOLOGY.md). The install picker default-applies `tokenmax` (it recommends `conservative` for Haiku-class subagent tiers or keyless setups); a brain with `search.mode` unset resolves to `balanced` at query time. The ZeroEntropy reranker is on in `balanced` and `tokenmax`, off in `conservative`. Per-query graph signals notice when a top result is a hub for THAT query (adjacency boost), is corroborated across team brains (cross-source boost), or is being crowded out by weak chunks from a chatty session (session demote). Run `gbrain search "<query>" --explain` to see per-stage attribution: base score, every boost that fired, what it multiplied. `gbrain doctor` ships a `graph_signals_coverage` check; `gbrain search stats` shows fire counts and failure breakdowns. Vector retrieval pools the best chunk per page, so a page surfaces on its strongest evidence instead of losing to a neighbor on one weak chunk. Queries that match a page's title phrase or a declared free-text alias (`gbrain reindex --aliases` backfills existing pages) get boosted to the page they name. Every result carries an `evidence` tag (why it matched) and a `create_safety` hint (`exists` / `probable` / `unknown`) so an agent decides whether a page already exists instead of guessing from a raw score. `gbrain search diagnose "<query>" --target <slug>` traces which retrieval layer surfaces (or misses) a page.

 **Self-wiring knowledge graph.** Every `put_page` extracts entity refs from markdown/wikilinks/typed-link syntax and writes edges with zero LLM calls. Typed edges (`attended`, `works_at`, `invested_in`, `founded`, `advises`, `mentions`, …). Multi-hop traversal via `gbrain graph-query`. The graph is what produces the +31.4 P@5 lift over vector-only RAG. **Obsidian-style vaults:** bare `[[note-name]]` wikilinks that point across folders — you wrote `[[struktura]]` but the page lives at `projects/struktura.md` — resolve by basename once you opt in with `gbrain config set link_resolution.global_basename true`. Off by default; `gbrain doctor` tells you how many edges you'd gain before you flip it. See [migrating an Obsidian vault](INSTALL_FOR_AGENTS.md#step-45-wire-the-knowledge-graph).

+### Synthesis cost control: the triage cascade
+
+The synthesize phase is a two-stage cascade: a cheap scored triage
+(utility-tier model, one call per new transcript) gates the expensive
+per-transcript synthesis subagents. The dials:
+
+- `dream.triage.threshold` (default 0.5) — the gate. Scores are cached, so
+  retuning it re-gates instantly with **zero** new LLM calls. Raise it if too
+  much routine content synthesizes; lower it if real signal is being skipped.
+- `models.dream.triage` — the triage model (default: utility tier / Haiku).
+- `dream.triage.max_chars` (default 24000, floor 1000) — per-transcript
+  sample window (head/middle/tail) sent to the judge. Not part of cache
+  validity — after changing it, `gbrain dream retriage --force` re-judges
+  under the new sampling.
+- `dream.triage.max_tokens` (default 2048, floor 256) — judge output budget.
+- `dream.triage.concurrency` (default 4, clamped 1–16) — concurrent judge
+  calls.
+- `dream.synthesize.max_turns` (default 16) — synthesis turn budget. The
+  triage map hands the subagent pre-extracted segments, so the mid-tier
+  default model (`models.dream.synthesize`, tier `reasoning`) with a 16-turn
+  budget is the intended pairing — frontier-model overrides are unnecessary
+  and slow the queue. Completeness comes from triage coverage (every file
+  scored, minus files deferred under the `max_ms` budget below) plus
+  segment-guided prompts, not model size. If written-page counts
+  drop after upgrading, set it back to 30 and check
+  `details.synthesis.avg_turns` for cap pressure.
+- `dream.triage.max_ms` (default 5 min) — per-cycle wall-clock budget for
+  judging NEW files; a big cold corpus triages across a few cycles (cached
+  files are free). Deferred files are labeled "not yet triaged", never
+  silently rejected.
+- `dream.synthesize.max_submissions_per_source_per_day` (default 0 = off) —
+  opt-in backstop cap on synthesis jobs per source; 200/day is a sane value
+  for busy deployments.
+
+Maintenance recipe — after changing the threshold, upgrading through a
+`TRIAGE_VERSION` bump, or to drain a queued synthesis backlog:
+
+```bash
+gbrain dream retriage --dry-run          # what would change (zero LLM calls)

+#
+# The docs/mcp/*-CLI-PIN.md files carry VERBATIM observation transcripts from
+# real installs (help output, saved configs, error copy). That verbatim
+# discipline is the point — but it is also exactly how an operator path
+# (/Users/<name>/…), a key fragment, or an account id ends up committed and
+# shipped with every release. This guard asserts the placeholder discipline:
+#
+#   1. No operator home paths: /Users/<name>/ or /home/<name>/ must appear as
+#      placeholders (<tmp>, $HOME, ~/) — never as a real username path.
+#      Bare `~/.grok`-style spellings are fine (that IS the placeholder).
+#   2. No key material: long high-entropy tokens with known prefixes
+#      (sk-…, xai-…, gbrain_<64+hex-ish>, ANTHROPIC/OPENAI/XAI key shapes).
+#      npm `sha512-…` integrity pins are EXPECTED content — excluded.
+#   3. No obvious account ids: emails outside example.com/invalid domains.

+procedure whenever the source is one of those six formats:
+
+```
+gbrain transcripts ingest ~/Downloads/conversations.json   # unzip first
+gbrain transcripts ingest                                  # discover harness logs
+gbrain transcripts status                                  # found vs imported gaps
+```
+
+Native-vs-manual delta to know: the native lane redacts SECRETS (key
+patterns) plus your `~/.gbrain/harvest-private-patterns.txt` regexes and
+counts agent-directed imperatives into frontmatter, but broad PII detection
+(names, phones, addresses) remains YOUR review pass — the manual procedure's
+human scrub step still applies to sensitive corpora. Two more deltas: the
+native lane caps each message at ~4K characters in the page body (readable
+archive, not verbatim — the session file named in `source_uri` stays the
+verbatim record), and tool/thinking traffic appears only as one-line
+placeholders. Providers without a native adapter (e.g. Perplexity) keep
+using the manual conversion below.

+# v0.46.3 migration — ZeroEntropy shutdown (ACTION REQUIRED before 2026-09-04)
+
+ZeroEntropy's hosted API — the former default for BOTH embedding (`zembed-1`)
+and reranking (`zerank-2`) — stops working on **2026-09-04**. A brain still
+resolving to `zeroentropyai:*` loses semantic retrieval ENTIRELY on that date
+(existing vectors become unqueryable, not just new content).
+
+**Nothing was changed automatically.** v0.46.3 only detects exposure and files
+this action item. The brain keeps working until the date. The switch itself
+costs money (a one-time re-embed) and needs a target API key, so it is the
+user's/agent's explicit call.
+
+## Agent action — when to run this migration
+
+Run the steps below when the user says anything like:
+
+- "ZeroEntropy" / "zembed" / "zerank" anything
+- "migrate my embeddings" / "switch embedding provider"
+- "search stopped working" / "embedding provider error" (after 2026-09-04)
+- "doctor says provider_sunset" / "gbrain is warning about a provider"
+- after any `gbrain upgrade` that printed the ACTION REQUIRED sunset block
+
+Also proactively surface it when `~/.gbrain/migrations/pending-host-work.jsonl`
+contains a `"migration": "0.46.3"` entry.
+
+## Step 1 — confirm exposure
+
+```bash
+gbrain doctor --json | jq '.checks[] | select(.name=="provider_sunset")'
+```
+
+`warn`/`fail` mentioning zeroentropyai = exposed. `ok` = already migrated
+(nothing to do; remove the pending-host-work entry).
+
+## Step 2 — pick the target by which key exists
+
+**Preferred — Voyage** (`VOYAGE_API_KEY` in env, or `voyage_api_key` in
+`~/.gbrain/config.json`). One key covers embedding + reranking + the
+multimodal model, and voyage-4 is the current hosted retrieval-quality
+leader. To set the key: `export VOYAGE_API_KEY=...` or edit
+`~/.gbrain/config.json` directly — do NOT use `gbrain config set
+voyage_api_key` (that writes the DB plane, which the embedding pipeline never
+reads).
+
+```bash
+gbrain migrate embeddings --to voyage:voyage-4 --dim 1024 --dry-run   # cost preview — show the user
+gbrain migrate embeddings --to voyage:voyage-4 --dim 1024 --yes
+```
+
+Note: **1280 is not a valid Voyage width** (valid: 256/512/1024/2048), so this
+includes a one-time schema/HNSW index rebuild to 1024. The command handles it;
+it is resumable if killed.
+
+**Alternative — OpenAI** (`OPENAI_API_KEY`). No reranker coverage, but OpenAI
+text-embedding-3 supports flexible widths, so a 1280d brain can keep its
+column (no schema rebuild):
+
+```bash
+gbrain migrate embeddings --to openai:text-embedding-3-small --dim 1280 --dry-run
+gbrain migrate embeddings --to openai:text-embedding-3-small --dim 1280 --yes
+# (or --dim 1536 for the model's native width — costs a schema rebuild)
+```
+
+**Neither key** — get one of the two (Voyage: https://dash.voyageai.com/api-keys),
+or self-host (below).
+
+## Step 3 — reranker
+
+If the doctor/notice flagged the reranker (balanced/tokenmax modes rerank with
+ZE zerank-2 by default until the removal release):
+
+```bash
+gbrain config set search.reranker.model voyage:rerank-2.5   # needs VOYAGE_API_KEY
+# or turn reranking off:
+gbrain config set search.reranker.enabled false
+```
+
+Without either, reranking silently fails open (no rerank, autocut off) after
+the shutdown date — search still works, ordering quality drops.
+
+## Step 4 — custom embedding columns (rare)
+
+If the notice listed ZE-backed `embedding_columns` entries: there is **no
+automated off-ramp** for custom columns yet (`migrate embeddings` covers the
+primary column only). Re-declare the column config on the new provider and
+re-embed its content, or drop the column config. A write-side custom-column
+migration is a filed follow-up (TODOS.md).
+
+## Step 5 — verify
+
+```bash
+gbrain doctor --json | jq '.checks[] | select(.name=="provider_sunset") | .status'   # → "ok"
+gbrain search "anything you know is in the brain"                                     # sanity check
+```
+
+Then remove/mark the `0.46.3` entry in
+`~/.gbrain/migrations/pending-host-work.jsonl` as done.
+
+## Self-hosting (zero re-embed, advanced)
+
+zembed-1's weights are Apache-2.0. Keeping vectors WITHOUT re-embedding
+requires keeping the `zeroentropyai:zembed-1` model id (the embedding
+signature must not change) and pointing its base URL at your own endpoint:
+
+```bash
+gbrain config set provider_base_urls.zeroentropyai http://your-host:PORT/v1
+```
+
+Two honest caveats:
+
+1. The endpoint must speak **ZeroEntropy's wire dialect** (`/models/embed`,
+   `{results: [...]}` responses) — a generic OpenAI-compatible llama-server or
+   Ollama endpoint will NOT work; you need a ZE-wire-compatible proxy in front.
+2. This works only until the September removal release deletes the
+   `zeroentropyai` recipe. A self-host continuity decision (possibly a compat
+   mode) is tracked in TODOS.md — if you rely on this path, follow that item.
+
+Switching the provider id instead (e.g. `llama-server:zembed-1`) changes
+`pages.embedding_signature`, and the next stale-embed pass re-embeds
+everything — that path is a full re-embed, not a zero-cost move.
+
+Note: `gbrain migrate embeddings` refuses `--to zeroentropyai:*` by default
+(it protects everyone else from re-embedding onto the dying hosted API). With
+your base-URL override in place, pass `--force-sunset-target` to proceed.
+
+## When NOT to run this migration
+
+- The brain is keyless (`embedding_disabled: true`) with no ZE reranker or
+  custom columns — nothing to migrate.
+- `provider_sunset` already reports `ok` — done; just clear the pending entry.
+- You only mounted someone else's brain: the migration is host-scoped; the
+  brain's owner migrates it (their upgrade banner + doctor nag them).

+ *      stale; `--dry-run` performs ZERO judge calls and reads cached scores
+ *      only). Spend-gated: prints an upfront estimate and asks for
+ *      confirmation above ~$5 (`--yes` skips; `--max-usd` soft-stops).
+ *   2. `--reconcile-queue` (opt-in — cancels queued work): parse every
+ *      waiting/delayed/paused `dream:synth-v2:*` job across ALL queues (the
+ *      live backlog largely sits in dead per-run `dream-inline-*` queues no
+ *      worker will ever drain), match (basename, hash16) to discovered
+ *      transcripts, then:
+ *        - matched below threshold      → cancel (frontier job not worth it)
+ *        - matched above, stale queue   → cancel as `converted_for_resubmit`
+ *          (cancelled rows release their idempotency slot, so the next cycle
+ *          re-adds them into ITS live private drain — this is what actually
+ *          migrates the backlog, outside-voice C1)
+ *        - matched above, live queue    → keep
+ *        - matched but unscored         → keep (never cancel on no data)
+ *        - unmatched                    → keep unless `--cancel-unmatched`
+ *        - key-source ≠ data.source_id  → skip + count (C9 hardening)

+NOTES
+  --cancel-unmatched cannot combine with --limit (a truncated corpus scan
+  would misclassify everything outside the slice as unmatched), and refuses
+  to run when discovery finds zero transcripts (a corpus-mount outage must
+  not erase the queued retry frontier). dream-inline-* queues younger than
+  1h are treated as possibly LIVE (a running cycle's drain) and are never
+  cancelled — they count as kept_live_queue. Running retriage while a cycle
+  is active may double-judge some cache misses (benign: last write wins).

+ *
+ *   A. Detects the HOST brain's exposure via src/core/ze-exposure.ts
+ *      (effective-model resolution — env → file → legacy fallback; plus the
+ *      resolved reranker and ZE-backed custom columns). Read-only.
+ *   B. When exposed (or exposure is UNKNOWN — fail-safe): prints the ACTION
+ *      REQUIRED block and appends one idempotent pending-host-work entry
+ *      pointing the host agent at skills/migrations/v0.46.3.0.md.
+ *
+ * It performs NO config writes, NO pinning, and NEVER invokes
+ * `migrate embeddings` (the migration costs money and needs a target key the
+ * user may not have — that decision belongs to the user/agent via the
+ * playbook). The v0.46.3 split-default keeps existing brains fully working
+ * until the date; this migration is purely the loud, durable notification.
+ *
+ * UNKNOWN handling: returns `complete` with detail `exposure_unknown` — NOT
+ * `partial`. Three consecutive partials would wedge the whole migration chain
+ * behind `--force-retry` (apply-migrations.ts); the stage-2 upgrade banner and
+ * `gbrain doctor` carry the ongoing nag instead.
+ *
+ * Host-scoped: apply-migrations runs once per host (global completed.jsonl).
+ * Mounted/team brains are covered by the per-brain stage-2 banner + doctor.
+ *
+ * NOTE: `apply-migrations --dry-run` exits before invoking orchestrators —
+ * the `opts.dryRun` path here is exercised by tests, not by that CLI flag.
