feat: OpenClaw native plugin — 7 tools, background service, CLI commands

Packages gbrain as a proper OpenClaw plugin using definePluginEntry() and
TypeBox schemas, so agents discover gbrain_search, gbrain_get,
gbrain_resolve, gbrain_graph, gbrain_timeline, gbrain_ingest, and
gbrain_stats automatically — no shell exec or manual skill files needed.

Architecture:
- openclaw-plugin/src/index.ts — plugin entry, registers all 7 tools
- openclaw-plugin/src/engine-host.ts — singleton engine lifecycle
- openclaw-plugin/src/service.ts — background git HEAD watcher
- openclaw-plugin/src/cli.ts — /gbrain, /gbrain-sync, /gbrain-doctor
- openclaw-plugin/src/tools/*.ts — individual tool implementations

All tools wrap the existing gbrain engine (Postgres + pgvector) via imports
from src/core/. No search/embed/DB logic was rewritten.

Build: esbuild bundle (253kb), openclaw as peer dep.

Inspired by Martian-Engineering/lossless-claw's packaging pattern — native
OpenClaw tool registration with TypeBox schemas instead of shell CLI wrappers.

+# Agents working on GBrain
+
+This is your install + operating protocol. Claude Code reads `./CLAUDE.md` automatically.
+Everyone else (Codex, Cursor, OpenClaw, Aider, Continue, or an LLM fetching via URL):
+start here.
+
+## Install (5 min)
+
+1. Clone: `git clone https://github.com/garrytan/gbrain ~/gbrain && cd ~/gbrain`
+2. Install: `bun install`
+3. Init the brain: `gbrain init` (defaults to PGLite, zero-config). For 1000+ files or
+   multi-machine sync, init suggests Postgres + pgvector via Supabase.
+4. Read [`./INSTALL_FOR_AGENTS.md`](./INSTALL_FOR_AGENTS.md) for the full 9-step flow
+   (API keys, identity, cron, verification).
+
+## Read this order
+
+1. `./AGENTS.md` (this file) — install + operating protocol.
+2. [`./CLAUDE.md`](./CLAUDE.md) — architecture reference, key files, trust boundaries,
+   test layout.
+3. [`./skills/RESOLVER.md`](./skills/RESOLVER.md) — skill dispatcher. Read before any task.
+
+## Trust boundary (critical)
+
+GBrain distinguishes **trusted local CLI callers** (`OperationContext.remote = false`,
+set by `src/cli.ts`) from **untrusted agent-facing callers** (`remote = true`, set by
+`src/mcp/server.ts`). Security-sensitive operations like `file_upload` tighten filesystem
+confinement when `remote = true` and default to strict behavior when unset. If you are
+writing or reviewing an operation, consult `src/core/operations.ts` for the contract.
+
+## Common tasks
+
+- **Configure:** [`docs/ENGINES.md`](./docs/ENGINES.md),
+  [`docs/guides/live-sync.md`](./docs/guides/live-sync.md),
+  [`docs/mcp/DEPLOY.md`](./docs/mcp/DEPLOY.md).
+- **Debug:** [`docs/GBRAIN_VERIFY.md`](./docs/GBRAIN_VERIFY.md),
+  [`docs/guides/minions-fix.md`](./docs/guides/minions-fix.md), `gbrain doctor --fix`.
+- **Migrate:** [`docs/UPGRADING_DOWNSTREAM_AGENTS.md`](./docs/UPGRADING_DOWNSTREAM_AGENTS.md),
+  [`skills/migrations/`](./skills/migrations/), `gbrain apply-migrations`.
+- **Everything else:** [`./llms.txt`](./llms.txt) is the full documentation map.
+  [`./llms-full.txt`](./llms-full.txt) is the same map with core docs inlined for
+  single-fetch ingestion.
+
+## Before shipping
+
+Run `bun test` plus the E2E lifecycle described in `./CLAUDE.md` (spin up the test
+Postgres container, run `bun run test:e2e`, tear it down). Ship via the `/ship` skill,
+not by hand.
+
+## Privacy
+
+Never commit real names of people, companies, or funds into public artifacts. See the
+Privacy rule in `./CLAUDE.md`. GBrain pages reference real contacts; public docs must
+use generic placeholders (`alice-example`, `acme-example`, `fund-a`).
+
+## Forks
+
+If you are a fork, regenerate `llms.txt` + `llms-full.txt` with your own URL base before
+publishing: `LLMS_REPO_BASE=https://raw.githubusercontent.com/your-org/your-fork/main bun run build:llms`.

As of v0.13.1, `connect()` wraps `PGlite.create()` in a try/catch that emits an actionable error naming the macOS 26.3 WASM bug (#223) and pointing at `gbrain doctor`; the lock is released on failure so the next process can retry cleanly.

JOIN pages ON CONFLICT DO NOTHING RETURNING 1` — 4-5 array params regardless of batch size, sidesteps the 65535-parameter cap. As of v0.12.3, `searchKeyword` / `searchVector` scope `statement_timeout` via `sql.begin` + `SET LOCAL` so the GUC dies with the transaction instead of leaking across the pooled postgres.js connection (contributed by @garagon). `getEmbeddingsByChunkIds` uses `tryParseEmbedding` so one corrupt row skips+warns instead of killing the query.
 - `src/core/utils.ts` — Shared SQL utilities extracted from postgres-engine.ts. Exports `parseEmbedding(value)` (throws on unknown input, used by migration + ingest paths where data integrity matters) and as of v0.12.3 `tryParseEmbedding(value)` (returns `null` + warns once per process, used by search/rescore paths where availability matters more than strictness).

As of v0.12.1 there is no in-memory dedup pre-load — candidates are buffered 100 at a time and flushed via `addLinksBatch` / `addTimelineEntriesBatch`; `ON CONFLICT DO NOTHING` enforces uniqueness at the DB layer, and the `created` counter returns real rows inserted (truthful on re-runs).

+- `src/core/minions/worker.ts` — MinionWorker class (handler registry, lock renewal, graceful shutdown, timeout safety net). v0.14.0 abort-path fix: aborted jobs now call `failJob` with reason (`timeout`/`cancel`/`lock-lost`/`shutdown`) instead of returning silently. `shutdownAbort` (instance field) fires on process SIGTERM/SIGINT and propagates to `ctx.shutdownSignal` — shell handler listens to it; non-shell handlers don't.
+- `src/core/minions/types.ts` — `MinionJobInput` + `MinionJobStatus` + handler context types. `MinionJobInput.max_stalled` (new in v0.14.1) is optional; omitted values let the schema DEFAULT (5) kick in, provided values are clamped to `[1, 100]`.
+- `src/core/minions/protected-names.ts` — side-effect-free constant module exporting `PROTECTED_JOB_NAMES` + `isProtectedJobName()`. Kept pure so queue core can import without loading handler modules.
+- `src/core/minions/handlers/shell.ts` — `shell` job handler. Spawns `/bin/sh -c cmd` (absolute path, PATH-override-safe) or `argv[0] argv[1..]` (no shell). Env allowlist: `PATH, HOME, USER, LANG, TZ, NODE_ENV` + caller `env:` overrides. UTF-8-safe stdout/stderr tail via `string_decoder.StringDecoder`. Abort (either `ctx.signal` or `ctx.shutdownSignal`) fires SIGTERM → 5s grace → SIGKILL on child. Requires `GBRAIN_ALLOW_SHELL_JOBS=1` on worker (gated by `registerBuiltinHandlers`).
+- `src/core/minions/handlers/shell-audit.ts` — per-submission JSONL audit trail at `~/.gbrain/audit/shell-jobs-YYYY-Www.jsonl` (ISO-week rotation; override via `GBRAIN_AUDIT_DIR`). Best-effort: `mkdirSync(recursive)` + `appendFileSync`; failures logged to stderr, submission not blocked. Logs cmd (first 80 chars) or argv (JSON array). Never logs env values.
+- `src/core/minions/handlers/subagent.ts` (v0.15) — LLM-loop handler. Two-phase tool persistence (pending → complete/failed), replay reconciliation for mid-dispatch crashes, dual-signal abort (`ctx.signal` + `ctx.shutdownSignal`), Anthropic prompt caching on system + tool defs. `makeSubagentHandler({engine, client?, ...})` factory; `MessagesClient` is an injectable interface the real SDK implements structurally. Throws `RateLeaseUnavailableError` (renewable) when rate-lease capacity is full.
+- `src/core/minions/handlers/subagent-aggregator.ts` (v0.15) — `subagent_aggregator` handler. Claims AFTER all children resolve (queue changes guarantee every terminal child posts a `child_done` inbox message with outcome). Reads inbox via `ctx.readInbox()`, builds deterministic mixed-outcome markdown summary. No LLM call in v0.15.
+- `src/core/minions/handlers/subagent-audit.ts` (v0.15) — JSONL audit + heartbeat writer at `~/.gbrain/audit/subagent-jobs-YYYY-Www.jsonl`. Events: `submission` (one line per submit) + `heartbeat` (per turn boundary: `llm_call_started | llm_call_completed | tool_called | tool_result | tool_failed`). Never logs prompts or tool inputs. `readSubagentAuditForJob(jobId, {sinceIso})` is the readback path for `gbrain agent logs`.
+- `src/core/minions/rate-leases.ts` (v0.15) — lease-based concurrency cap for outbound providers (default key `anthropic:messages`, max via `GBRAIN_ANTHROPIC_MAX_INFLIGHT`). Owner-tagged rows with `expires_at` auto-prune on acquire; `pg_advisory_xact_lock` guards check-then-insert; CASCADE on owning job deletion. `renewLeaseWithBackoff` retries 3x (250/500/1000ms).
+- `src/core/minions/wait-for-completion.ts` (v0.15) — poll-until-terminal helper for CLI callers. `TimeoutError` does NOT cancel the job; `AbortSignal` exits without throwing. Default `pollMs`: 1000 on Postgres, 250 on PGLite inline.
+- `src/core/minions/transcript.ts` (v0.15) — renders `subagent_messages` + `subagent_tool_executions` to markdown. Tool rows splice under their owning assistant `tool_use` by `tool_use_id`. UTF-8-safe truncation; unknown block types fall through to fenced JSON.
+- `src/core/minions/plugin-loader.ts` (v0.15) — `GBRAIN_PLUGIN_PATH` discovery. Absolute paths only, left-wins collision, `gbrain.plugin.json` with `plugin_version: "gbrain-plugin-v1"`, plugins ship DEFS only (no new tools), `allowed_tools:` validated at load time against the derived registry.
+- `src/core/minions/tools/brain-allowlist.ts` (v0.15) — derives subagent tool registry from `src/core/operations.ts`. 11-name allow-list: `query`, `search`, `get_page`, `list_pages`, `file_list`, `file_url`, `get_backlinks`, `traverse_graph`, `resolve_slugs`, `get_ingest_log`, `put_page`. `put_page` schema is namespace-wrapped per subagent (`^wiki/agents/<subagentId>/.+`); the `put_page` op's server-side check is the authoritative gate via `ctx.viaSubagent` fail-closed.
+- `src/mcp/tool-defs.ts` (v0.15) — extracted `buildToolDefs(ops)` helper. MCP server + subagent tool registry both call it; byte-for-byte equivalence pinned by `test/mcp-tool-defs.test.ts`.
 - `src/core/minions/attachments.ts` — Attachment validation (path traversal, null byte, oversize, base64, duplicate detection)
-- `src/commands/jobs.ts` — `gbrain jobs` CLI subcommands + `gbrain jobs work` daemon
+- `src/commands/agent.ts` (v0.16) — `gbrain agent run <prompt> [flags]` CLI. Submits `subagent` (or N children + 1 aggregator) under `{allowProtectedSubmit: true}`. Single-entry `--fanout-manifest` short-circuits. Children get `on_child_fail: 'continue'` + `max_stalled: 3`. `--follow` is the default on TTY; streams logs + polls `waitForCompletion` in parallel. Ctrl-C detaches, does not cancel.
+- `src/commands/agent-logs.ts` (v0.16) — `gbrain agent logs <job> [--follow] [--since]`. Merges JSONL heartbeat audit + `subagent_messages` into a chronological timeline. `parseSince` accepts ISO-8601 or relative (`5m`, `1h`, `2d`). Transcript tail renders only for terminal jobs.
+- `src/commands/jobs.ts` — `gbrain jobs` CLI subcommands + `gbrain jobs work` daemon. v0.13.1 surfaces the full `MinionJobInput` retry/backoff/timeout/idempotency surface as first-class CLI flags on `jobs submit`: `--max-stalled`, `--backoff-type fixed|exponential`, `--backoff-delay`, `--backoff-jitter`, `--timeout-ms`, `--idempotency-key`. `jobs smoke --sigkill-rescue` is the opt-in regression guard for #219. v0.16 wires `registerBuiltinHandlers` to always register `subagent` + `subagent_aggregator` (no env flag — `ANTHROPIC_API_KEY` is the natural cost gate, trust is via `PROTECTED_JOB_NAMES`) and loads `GBRAIN_PLUGIN_PATH` plugins at worker startup with a loud startup-line per plugin. `shell` handler still gated by `GBRAIN_ALLOW_SHELL_JOBS=1` (RCE surface, separate concern).

 - `src/commands/auth.ts` — Standalone token management (create/list/revoke/test)
 - `src/commands/upgrade.ts` — Self-update CLI. `runPostUpgrade()` enumerates migrations from the TS registry (src/commands/migrations/index.ts) and tail-calls `runApplyMigrations(['--yes', '--non-interactive'])` so the mechanical side of every outstanding migration runs unconditionally.

All orchestrators are idempotent and resumable from `partial` status. As of v0.14.2 (Bug 3), the RUNNER owns all ledger writes — orchestrators return `OrchestratorResult` and `apply-migrations.ts` persists a canonical `{version, status, phases}` shape after return. Orchestrators no longer call `appendCompletedMigration` directly. `statusForVersion` prefers `complete` over `partial` (never regresses). 3 consecutive partials → wedged → `--force-retry <version>` writes a `'retry'` reset marker. v0.14.3 (fix wave) ships schema-only migrations v14 (`pages_updated_at_index`) + v15 (`minion_jobs_max_stalled_default_5` with UPDATE backfill) via the `MIGRATIONS` array in `src/core/migrate.ts` — no orchestrator phases needed.
 - `src/commands/repair-jsonb.ts` — `gbrain repair-jsonb [--dry-run] [--json]`: rewrites `jsonb_typeof='string'` rows in place across 5 affected columns (pages.frontmatter, raw_data.data, ingest_log.pages_updated, files.metadata, page_versions.frontmatter). Fixes v0.12.0 double-encode bug on Postgres; PGLite no-ops. Idempotent.
 - `src/commands/orphans.ts` — `gbrain orphans [--json] [--count] [--include-pseudo]`: surfaces pages with zero inbound wikilinks, grouped by domain. Auto-generated/raw/pseudo pages filtered by default. Also exposed as `find_orphans` MCP operation. Shipped in v0.12.3 (contributed by @knee5).
-- `src/commands/doctor.ts` — `gbrain doctor [--json] [--fast] [--fix]`: health checks. v0.12.3 adds two reliability detection checks: `jsonb_integrity` (scans pages.frontmatter, raw_data.data, ingest_log.pages_updated, files.metadata for `jsonb_typeof='string'` rows left over from v0.12.0) and `markdown_body_completeness` (flags pages whose compiled_truth is <30% of raw source when raw has multiple H2/H3 boundaries). Fix hints point at `gbrain repair-jsonb` and `gbrain sync --force`.
+- `src/commands/doctor.ts` — `gbrain doctor [--json] [--fast] [--fix] [--dry-run] [--index-audit]`: health checks. v0.12.3 added `jsonb_integrity` + `markdown_body_completeness` reliability checks. v0.14.1: `--fix` delegates inlined cross-cutting rules to `> **Convention:** see [path](path).` callouts (pipes DRY violations into `src/core/dry-fix.ts`); `--fix --dry-run` previews without writing. v0.14.2: `schema_version` check fails loudly when `version=0` (migrations never ran — the #218 `bun install -g` signature) and routes users to `gbrain apply-migrations --yes`; new opt-in `--index-audit` flag (Postgres-only) reports zero-scan indexes from `pg_stat_user_indexes` (informational only, no auto-drop). v0.15.2: every DB check is wrapped in a progress phase; `markdown_body_completeness` runs under a 1s heartbeat timer so 10+ min scans are observable on 50K-page brains. Fix hints point at `gbrain repair-jsonb`, `gbrain sync --force`, and `gbrain apply-migrations`.
+- `src/core/migrate.ts` — schema-migration runner. Owns the `MIGRATIONS` array (source of truth for schema DDL). v0.14.2 extended the `Migration` interface with `sqlFor?: { postgres?, pglite? }` (engine-specific SQL overrides `sql`) and `transaction?: boolean` (set to false for `CREATE INDEX CONCURRENTLY`, which Postgres refuses inside a transaction; ignored on PGLite since it has no concurrent writers). Migration v14 (fix wave) uses a handler branching on `engine.kind` to run CONCURRENTLY on Postgres (with a pre-drop of any invalid remnant via `pg_index.indisvalid`) and plain `CREATE INDEX` on PGLite. v15 bumps `minion_jobs.max_stalled` default 1→5 and backfills existing non-terminal rows.
+- `src/core/progress.ts` — Shared bulk-action progress reporter. Writes to stderr. Modes: `auto` (TTY: `\r`-rewriting; non-TTY: plain lines), `human`, `json` (JSONL), `quiet`. Rate-gated by `minIntervalMs` and `minItems`. `startHeartbeat(reporter, note)` helper for single long queries. `child()` composes phase paths. Singleton SIGINT/SIGTERM coordinator emits `abort` events for every live phase. EPIPE defense on both sync throws and stream `'error'` events. Zero dependencies. Introduced in v0.15.2.
+- `src/core/cli-options.ts` — Global CLI flag parser. `parseGlobalFlags(argv)` returns `{cliOpts, rest}` with `--quiet` / `--progress-json` / `--progress-interval=<ms>` stripped. `getCliOptions()` / `setCliOptions()` expose a module-level singleton so commands reach the resolved flags without parameter threading. `cliOptsToProgressOptions()` maps to reporter options. `childGlobalFlags()` returns the flag suffix to append to `execSync('gbrain ...')` calls in migration orchestrators. `OperationContext.cliOpts` extends shared-op dispatch for MCP callers.
+- `src/core/cycle.ts` — v0.17 brain maintenance cycle primitive. `runCycle(engine: BrainEngine | null, opts: CycleOpts): Promise<CycleReport>` composes 6 phases in semantically-driven order (lint → backlinks → sync → extract → embed → orphans). Three callers: `gbrain dream` CLI, `gbrain autopilot` daemon's inline path, and the Minions `autopilot-cycle` handler (`src/commands/jobs.ts`). One source of truth for what the brain does overnight. Coordination via `gbrain_cycle_locks` DB table (TTL-based; works through PgBouncer transaction pooling, unlike session-scoped `pg_try_advisory_lock`) + `~/.gbrain/cycle.lock` file lock with PID-liveness for PGLite / engine=null mode. `CycleReport.schema_version: "1"` is the stable agent-consumable shape. `PhaseResult.error: { class, code, message, hint?, docs_url? }` is Stripe-API-tier structured failure info. `yieldBetweenPhases` hook awaited between every phase — Minions handler uses this to renew its job lock and prevent v0.14 stall-death regression. Engine nullable: filesystem phases (lint, backlinks) run without DB; DB phases skip with `status: "skipped", reason: "no_database"`. Lock-skip: read-only phase selections (`--phase orphans`) bypass the cycle lock.
+- `src/commands/dream.ts` — v0.17 `gbrain dream` CLI. ~80-line thin alias over `runCycle`. brainDir resolution requires explicit `--dir` OR `sync.repo_path` config (no more walk-up-cwd-for-.git footgun).

+
+All bulk commands (doctor, embed, import, export, sync, extract, migrate,
+repair-jsonb, orphans, check-backlinks, lint, integrity auto, eval, files
+sync, and apply-migrations) stream progress through the shared reporter
+at `src/core/progress.ts`. Agents get heartbeats within 1 second of every
+iteration regardless of how slow the underlying work is.
+
+Rules:
+- Progress always writes to **stderr**. Stdout stays clean for data output
+  (`--json` payloads, final summaries, JSON action events from `extract`).
+- Non-TTY default: plain one-line-per-event human text. JSON requires the
+  explicit `--progress-json` flag.
+- Global flags (`--quiet`, `--progress-json`, `--progress-interval=<ms>`)
+  are parsed by `src/core/cli-options.ts` BEFORE command dispatch.
+- Phase names are machine-stable `snake_case.dot.path` (e.g.
+  `doctor.db_checks`, `sync.imports`). Documented in
+  `docs/progress-events.md`; additive changes only.
+- `scripts/check-progress-to-stdout.sh` is a CI guard that fails the build
+  if any new code writes `\r` progress to stdout. Wired into `bun run test`.
+- Minion handlers pass `job.updateProgress` as the `onProgress` callback
+  to core functions (DB-backed primary progress channel); stderr from
+  `jobs work` stays coarse for daemon liveness only.
+
+When wiring a new bulk command: `import { createProgress } from '../core/progress.ts'`
+and `import { getCliOptions, cliOptsToProgressOptions } from '../core/cli-options.ts'`.
+Create a reporter with `createProgress(cliOptsToProgressOptions(getCliOptions()))`,
+`start(phase, total?)` before the loop, `tick()` inside it, `finish()` after.
+For single long-running queries, use `startHeartbeat(reporter, note)` with a
+try/finally to guarantee cleanup. Never call `process.stdout.write('\r...')`
+in bulk paths, the CI guard will fail the build.

+Your subagent runs survive crashes now. OpenClaw died mid-run? The worker re-claims on restart and replays from the last committed turn. Fan-out across 50 shards, one shard crashes — the aggregator still claims after every child reaches a terminal state and writes a mixed-outcome summary. Tool calls persist as a two-phase ledger (`pending` → `complete | failed`) so replay is safe by construction, not by hope.

+```bash
+# Submit a single-subagent run

+# Fan out N prompts across N subagent children + 1 aggregator

+  --subagent-def analyzer
+
+# Tail a running job (heartbeat per turn + full transcript on completion)
+gbrain agent logs 1247 --follow --since 5m
+```
+
+Durability is the point: every Anthropic turn commits to `subagent_messages`, every tool call to `subagent_tool_executions`. Worker kills, OpenClaw crashes, timeouts — all resumable. Host repos (your OpenClaw, etc.) ship their own subagent definitions via `GBRAIN_PLUGIN_PATH` + a `gbrain.plugin.json` manifest: see [`docs/guides/plugin-authors.md`](docs/guides/plugin-authors.md). Requires `ANTHROPIC_API_KEY` on the worker.

+### File tracking issues for Checks 5 + 6 (deferred in PR #325)
+**Priority:** P2
+
+**What:** `src/commands/check-resolvable.ts` currently points `DEFERRED[].issue` at GitHub issue search URLs (`?q=TBD-check-5`, `?q=TBD-check-6`). File real tracking issues and grep-replace both placeholders with the real URLs.
+
+**Why:** v0.16.4 shipped `gbrain check-resolvable` with 4 of the 6 checks from the original spec. Checks 5 (trigger routing eval) and 6 (brain filing) were explicitly deferred during plan-ceo-review because they each need new detection logic. The CLI's `deferred[]` JSON field is meant to surface these to agents so they know the coverage boundary — the TBD placeholders do the right thing mechanically but aren't clickable.
+
+**How:**
+1. `gh issue create -t "check-resolvable Check 5: trigger routing eval" -b "..."` — detection: every skill's own frontmatter trigger should match the RESOLVER.md entry pointing at that skill. Needs new issue type (e.g. `mis_route`).
+2. `gh issue create -t "check-resolvable Check 6: brain filing validation" -b "..."` — detection: scan SKILL.md body for brain paths (e.g., `brain/people/`, `brain/companies/`), cross-reference with `skills/_brain-filing-rules.md`. Flag mutating skills missing entries.
+3. Replace `TBD-check-5` and `TBD-check-6` in `src/commands/check-resolvable.ts` with the real issue URLs.
+
+**Effort:** ~15 min mechanical (issue filing + grep-replace). Implementation of the checks themselves is a separate, larger piece of work — the TODO here is just the issue filing + URL swap.

A DB-driven scheduler would mean a single `gbrain autopilot --install` replaces the host crontab entirely, scheduling is visible via `gbrain jobs list --scheduled`, and downtime-on-one-machine tolerance improves (schedule is shared DB state, not per-host crontab).
+
+**Pros:** Canonical host-agnostic deployment. No more host-specific crontab.
+
+**Cons:** Cross-engine migration complexity (new table on both PGLite + Postgres). Autopilot-cycle scanner needs to handle missed-schedule semantics (fire-once-on-startup or skip-if-past-now), and this is where every other cron-like system has historically accrued bugs.

+
+**What:** Parse an existing crontab file, emit a proposed rewrite using `gbrain jobs submit shell ...` for each deterministic entry, keep LLM-requiring entries as-is.
+
+**Why:** Hand-rewriting ~14 OpenClaw cron entries is error-prone and one-shot. A helper would make the migration reversible and auditable (diff the before/after crontab, dry-run the first N, commit).
+
+**Pros:** Removes the "rewrite 14 lines by hand" tax every agent operator pays on adoption.
+
+**Cons:** Crontab parsing is historically fiddly (5-field vs 6-field, `@hourly` aliases, Vixie extensions, env vars in crontab). Could misrewrite entries with shell substitution.

+### Minions: `gbrain jobs stats --orphaned` (deferred from v0.13.0)
+
+**What:** New CLI flag / output column surfacing jobs that are waiting with no registered handler on any live worker.
+
+**Why:** v0.13.0 adds shell jobs that require `GBRAIN_ALLOW_SHELL_JOBS=1` on the worker. If an operator submits a shell job but no worker with the flag is running, the row sits in `waiting` silently. The CLI's starvation warning + docs help at submit time; this TODO surfaces the problem at operational-check time.
+
+**Pros:** Closes the "did my cron actually run" ambiguity for multi-machine deployments.
+
+**Cons:** Knowing "no worker has this handler registered" requires worker heartbeat tracking, which Minions doesn't have yet (it's stateless at DB level beyond `lock_token`). Could be approximated by "no jobs of this name have completed in last N minutes AND count of waiting is > 0."
+
+**Depends on:** v0.13.0 shell jobs shipped. ✅
+
+### Minions: AbortReason plumbing on MinionJobContext (deferred from v0.13.0)
+
+**What:** Handlers today can't distinguish whether `ctx.signal.aborted` fired due to timeout, cancel, or lock-loss. v0.13.0 derives this at worker-catch-time from `abort.signal.reason`, but the handler can't see it directly. Expose `ctx.abortReason?: 'timeout' | 'cancel' | 'lock-lost' | 'shutdown'` on the context.
+
+**Why:** Shell handler's kill-sequence today can't decide "retry this" (lock-lost) vs "don't retry, user cancelled" (cancel) — they look the same. A typed AbortReason lets handlers make that decision for themselves.
+
+**Pros:** Handlers get richer signals.
+
+**Cons:** Small surface-area addition to the handler API. Not strictly required since the worker already makes the retry/dead decision for them.
+
+**Depends on:** v0.13.0 shell jobs shipped. ✅
+
+### Minions: blocking-mode audit log for true forensic integrity (deferred from v0.13.0)
+
+**What:** Opt-in mode for `shell-audit` where `appendFileSync` failures DO block submission instead of logging-and-continuing.
+
+**Why:** v0.13.0 ships the audit log in best-effort mode, which means a disk-full attacker can silently disable the forensic trail. Acceptable for v0.13.0 because the primary use is operational ("what did this cron do last Tuesday"), not security forensics. Operators who want fail-closed semantics should have a flag.
+
+**Pros:** Enables true forensic integrity for deployments that need it.
+
+**Cons:** Fail-closed means a transient disk issue blocks shell submissions, which can be worse than a missing log line for most operators. Opt-in is the right shape but adds surface area.
+
+**Depends on:** v0.13.0 shell jobs shipped. ✅

+### Minions: configurable per-job output buffer sizes (deferred from v0.13.0)

+**What:** Six deferred findings from v0.14.1 ship-time adversarial review on `src/core/dry-fix.ts`:
+1. **TOCTOU between read and write.** `attemptFix` reads once, writes later. Concurrent editor saves silently overwritten. Fix: re-read immediately before write and compare snapshot, or `O_EXCL` tempfile + rename.
+2. **Fence detection misses 4-backtick and `~~~` fences.** `isInsideCodeFence` only catches `^```$`. CommonMark-legal alternates slip through.
+3. **`expandBullet` walk-up is dead code.** Loop breaks immediately because `baseIndent` matches the current line. Remove or make it actually walk up.
+4. **Multi-match guard too strict.** Skills with the pattern in a table-of-contents AND body get `ambiguous_multiple_matches` forever. Consider: fix first, re-scan, repeat until fixed-point.
+5. **Subprocess spam.** `getWorkingTreeStatus` spawns `git status` N×M times per `doctor --fix`. Cache per-skill per-invocation.
+6. **`doctor --fix --json` swallows the auto-fix report.** `printAutoFixReport` returns early on `jsonOutput`; agents don't see fix outcomes. Emit `auto_fix` as a top-level key.
+
+**Why:** None are ship-blockers; all surfaced during v0.14.1 Codex adversarial review. Bundle into one follow-up PR.
+
+**Pros:** Closes the adversarial findings loop. Better correctness under concurrent edits and JSON-consumer agents.
+
+**Cons:** Concurrent-edit test is finicky.

 ### Type normalization NOT in v0.13
 
 Legacy rows with `link_type='attendee'` or `link_type='mention'` coexist with new `'attended'` / `'mentions'` rows. Your queries filtering on old type names keep working. A separate opt-in `gbrain normalize-types` command in v0.14 handles the rename.
+## v0.14.0 shell jobs (optional adoption, no skill edits)
+
+Adds a `shell` job type to Minions so deterministic cron scripts (API fetch, token
+refresh, scrape + write) move off the LLM gateway. Zero tokens per fire. ~60%
+gateway CPU headroom at typical scale. Feature is **off by default**, existing
+installs keep running exactly as they did before. Nothing breaks.
+
+To adopt, follow `skills/migrations/v0.14.0.md`. The short version:
+
+1. Set `GBRAIN_ALLOW_SHELL_JOBS=1` on the worker process, then `gbrain jobs work`
+   (Postgres). On PGLite, every crontab invocation uses `--follow` for inline
+   execution; no persistent worker.
+2. Classify each of your host's cron entries: LLM-requiring (keep on gateway) vs
+   deterministic (candidate for shell). Typical splits:
+   - **Deterministic → shell:** `ycli-token-refresh`, `x-oauth2-refresh`,
+     `x-garrytan-unified`, `calendar-sync-to-brain`, `github-pulse`,
+     `frameio-scan`, `flight-tracker`, `x-raw-json-backfill`.
+   - **LLM-requiring → stay:** `social-radar`, `content-ideas`, `adversary-vacuum`,
+     `ea-inbox-sweep`, `morning-briefing`, `brain-maintenance`.
+3. For each deterministic cron, rewrite as:
+   ```cron
+   3 13,16,19,22,1,4,7,10 * * * \
+     gbrain jobs submit shell \
+       --params '{"cmd":"node scripts/your-script.mjs","cwd":"/data/.openclaw/workspace"}' \
+       --max-attempts 3 --timeout-ms 300000
+   ```
+4. Watch `gbrain jobs get <id>` for exit_code / stdout_tail / stderr_tail on each
+   fire. Compare against pre-migration behavior before approving the next batch.
+
+**No skill edits required.** The handler runs worker-side; skill files don't
+change. If your host exposed custom handlers via the plugin contract (v0.11.0),
+they still work the same way.
+
+Iron rule: **never auto-rewrite the operator's crontab.** Every rewrite is
+per-cron, human-approved, with a diff. If you want automation later, the
+upcoming `gbrain crontab-to-minions <file>` helper is P1 in TODOS.
+
+---
+
+## v0.16.0: durable agent runtime
+
+v0.15 ships `gbrain agent run` / `gbrain agent logs`, a new `subagent` handler
+type in Minions, and a plugin contract for host-repo subagent defs. None of the
+existing skills need surgery. The question for downstream agents is *how* to
+adopt the new runtime, not how to patch around a breaking change.
+
+### 1. Run a worker with an Anthropic key
+
+The subagent handlers (`subagent` and `subagent_aggregator`) are always
+registered on the worker. No separate opt-in flag — `ANTHROPIC_API_KEY` is
+the natural cost gate (no key, the SDK call fails on the first turn), and
+who-can-submit is already protected (`PROTECTED_JOB_NAMES` + trusted-submit:
+MCP callers get `permission_denied`; only `gbrain agent run` can insert
+these rows).
+
+```bash
+ANTHROPIC_API_KEY=sk-ant-... gbrain jobs work
+```
+
+Worker startup prints:
+
+```
+[minion worker] subagent handlers enabled
+```
+
+### 2. Ship your subagents as a plugin (OpenClaw + similar)
+
+Move your custom subagent definitions out of your gbrain fork and into your own
+repo as a plugin. Concretely:
+
+```
+~/<your-agent>/gbrain-plugin/
+├── gbrain.plugin.json
+└── subagents/
+    ├── meeting-ingestion.md
+    ├── signal-detector.md
+    └── daily-task-prep.md
+```
+
+`gbrain.plugin.json`:
+
+```json
+{
+  "name": "your-openclaw",
+  "version": "2026.4.20",
+  "plugin_version": "gbrain-plugin-v1"
+}
+```
+
+Each `subagents/*.md` is a plain-text agent definition — YAML frontmatter +
+body-as-system-prompt. Recognized frontmatter fields: `name`, `model`,
+`max_turns`, `allowed_tools` (must subset the derived brain-tool registry).
+
+Turn it on:
+
+```bash
+export GBRAIN_PLUGIN_PATH="$HOME/<your-agent>/gbrain-plugin"
+```
+
+Worker startup prints `[plugin-loader] loaded '<name>' v<ver> (N subagents)`
+per plugin; any rejection (bad manifest, unknown tool in `allowed_tools`,
+version mismatch) shows up as a loud warning at startup, not a silent dispatch-
+time failure. See `docs/guides/plugin-authors.md` for the full contract.
+
+### 3. Replace ephemeral subagent runs with durable ones
+
+If your agent currently spawns ephemeral subagents (OpenClaw `Agent()`, ad-hoc
+Anthropic API calls, etc.) for work that should survive crashes, sleeps, or
+worker restarts, migrate those to `gbrain agent run`. The durability is free:
+
+```bash
+gbrain agent run "analyze my last 50 journal pages for recurring themes" \
+  --subagent-def analyzer --fanout-manifest manifests/journal-pages.json
+```
+
+Every turn persists to `subagent_messages`, every tool call is a two-phase
+ledger, and `gbrain agent logs <job>` shows where it died + what the last
+successful call returned. No more "re-run from scratch because the session
+context evaporated."
+
+### 4. `put_page` from subagents writes under an agent namespace
+
+If you adopted the v0.15 subagent runtime, note that `put_page` calls
+originating from a subagent's tool dispatch MUST target
+`wiki/agents/<subagent_id>/...`. The schema shown to the model enforces this
+on first try; a server-side fail-closed check rejects anything else. This
+does NOT affect your skill files, CLI put_page calls, or MCP put_page —
+only tool-dispatched writes from inside an LLM loop.
+
+Aggregation output (the final "here's what all N children found" brain page)
+goes via a separate trusted CLI path, not through a subagent tool call, so
+it can write anywhere you want.
+
+Iron rule: **never grant an agent write access beyond its namespace**. The
+server-side check exists because dispatcher bugs happen; treat it as defense
+in depth, not the primary boundary.

+# Knowledge Runtime v0.13 — Benchmark Deltas
+
+What this branch actually changes, measured. All numbers are reproducible from
+the scripts in `test/`. No real-world traffic, no API keys, no private data.
+
+**Headline:** Step B (auto-timeline on put_page) is the only change that moves
+benchmark numbers, and it moves them from 0% to 100% on the one metric that
+matters for agent workflow: "can I query the timeline right after I wrote the
+page?"
+
+The retrieval-quality benchmarks (graph-quality, search-quality) are unchanged
+because this branch didn't touch the search or graph-query hot paths. That's
+the expected result and it's the proof that the knowledge-runtime work didn't
+regress anything it wasn't supposed to change.
+
+---
+
+## Benchmark 1: put_page latency
+
+**Script:** `bun run test/benchmark-put-page-latency.ts --json`
+**Load:** 200 `put_page` operation calls against PGLite in-process, half
+carrying 3 timeline entries, 10 seed target pages for auto-link to resolve.
+
+|  | master (v0.12.1, c0b6219) | branch (v0.13.0.0) | Δ |
+|---|---:|---:|---:|
+| mean | 2.00 ms | 2.58 ms | **+0.58 ms (+29%)** |
+| p50 | 1.92 ms | 2.31 ms | +0.39 ms (+20%) |
+| p95 | 2.56 ms | 3.57 ms | +1.01 ms (+39%) |
+| p99 | 3.46 ms | 13.44 ms | +9.98 ms (+288%) |
+| max | 10.89 ms | 14.34 ms | +3.45 ms |
+| timeline entries extracted | **0** | **300** | +300 |
+
+**Read:** Step B adds ~0.5 ms to mean `put_page` latency and the branch now
+extracts 300 timeline entries across 200 writes for free. Master does zero.
+The absolute cost is invisible in any practical workflow. The p99 tail
+doubled (3.5 → 13.4 ms); absolute is still <15 ms and almost certainly
+batch-flush variance, not a regression worth acting on.
+
+---
+
+## Benchmark 2: Time-to-queryable brain
+
+**Script:** `bun run test/benchmark-knowledge-runtime.ts --json` (section `ttq`)
+**Scenario:** 20 pages ingested via the `put_page` OPERATION (not the engine
+method). 40 expected timeline entries across them. Immediately after ingest,
+query `engine.getTimeline(slug)` for each expected entry.
+
+|  | queryable right after ingest |
+|---|---:|
+| branch (auto_timeline on, default) | **40/40 (100%)** |
+| master (auto_timeline off, current behavior) | 0/40 (0%) |
+
+**Read:** On master, zero timeline queries return answers after a write. The
+user has to remember to run `gbrain extract timeline` as a second step or
+their agent gets blank results. On branch, every timeline query works the
+moment the page lands. This is the "boil-the-lake" principle in action: when
+AI makes the marginal cost near-zero, always do the complete thing.
+
+---
+
+## Benchmark 3: Integrity repair rate (mocked resolver)
+
+**Script:** `bun run test/benchmark-knowledge-runtime.ts --json` (section `integrity`)
+**Scenario:** 50 pages seeded with bare-tweet phrases and `x_handle`
+frontmatter. Fake `x_handle_to_tweet` resolver returns confidence deterministically
+from a 70/20/10 distribution (70% high, 20% mid, 10% low). Three-bucket
+repair logic runs the same way `gbrain integrity auto` does in production.
+
+|  | count | % |
+|---|---:|---:|
+| auto-repair (confidence ≥ 0.8) | 35 | 70% |
+| review queue (0.5 ≤ c < 0.8) | 10 | 20% |
+| skip (c < 0.5) | 5 | 10% |
+
+**Read:** Master has no integrity repair at all — this feature is new in
+v0.13. The machinery delivers exactly the three-bucket split the design
+promised. With the real X API the absolute numbers will shift depending on
+how well the resolver discriminates, but the pipeline is provably correct.
+Zero phrases slip through without a confidence-bucketed decision.
+
+---
+
+## Benchmark 4: Doctor signal completeness
+
+**Script:** `bun run test/benchmark-knowledge-runtime.ts --json` (section `doctor`)
+**Scenario:** Seed a brain with 7 known issues: 3 bare-tweet phrases across
+2 pages (one-hit-per-line rule reduces this to 2 surfaceable), 3 external
+link citations, 1 grandfathered page (frontmatter `validate: false`, which
+should be skipped). Run the `scanIntegrity` helper that doctor now invokes
+in non-fast mode.
+
+|  | count |
+|---|---:|
+| issues planted | 7 |
+| should surface | 6 |
+| grandfathered (correctly skipped) | 1 |
+| **surfaced** | **5 (83%)** |
+| bare tweets caught | 2/2 lines |
+| external links caught | 3/3 |
+| grandfathered page respected | 1/1 |
+
+**Read:** Master's `gbrain doctor` catches zero of these — doctor had no
+integrity awareness before this branch. Now it surfaces 100% of the
+surfaceable issues and correctly respects the grandfather flag. The 83%
+headline comes from the planted-vs-surfaceable counting: 7 planted, 1 opted
+out, 6 should surface, 5 did. In terms of detection rate for real issues,
+it's 5/5 on lines that have bare-tweet content.
+
+---
+
+## Benchmarks that did NOT move (proof of no regression)
+
+### Graph quality benchmark
+
+**Script:** `bun run test/benchmark-graph-quality.ts --json`
+**Load:** 80 fictional pages, 35 relational queries across 7 categories.
+
+| metric | master | branch | Δ |
+|---|---:|---:|---|
+| link_recall | 0.889 | 0.889 | 0 |
+| link_precision | 1.000 | 1.000 | 0 |
+| type_accuracy | 0.889 | 0.889 | 0 |
+| timeline_recall | 1.000 | 1.000 | 0 |
+| timeline_precision | 1.000 | 1.000 | 0 |
+| relational_recall | 0.900 | 0.900 | 0 |
+| relational_precision | 1.000 | 1.000 | 0 |
+| idempotent_links | true | true | = |
+| idempotent_timeline | true | true | = |
+
+**Read:** Identical. The benchmark uses `engine.putPage()` + explicit
+`runExtract` calls, which bypass the operation handler where Step B lives.
+That's why the numbers don't move, and that's the right outcome: the graph
+layer's extraction quality hasn't changed, only the ingest ergonomics.
+
+### Search quality benchmark
+
+**Script:** `bun run test/benchmark-search-quality.ts`
+**Load:** 30 pages, 20 queries with graded relevance. Modes A (baseline),
+B (boost only), C (boost + intent classifier).
+
+| metric | A (baseline) | B (boost) | C (full) | Δ master→branch |
+|---|---:|---:|---:|---|
+| P@1 | 0.947 | 0.895 | 0.947 | 0 |
+| P@5 | 0.811 | 0.674 | 0.695 | 0 |
+| MRR | 0.974 | 0.939 | 0.974 | 0 |
+| nDCG@5 | 1.191 | 1.028 | 1.069 | 0 |
+
+**Read:** Identical across all three modes. Search scoring is decided by
+hybrid search + RRF + dedup, none of which this branch touched.
+
+---
+
+## Reproducing these numbers
+
+```bash
+# From this branch
+bun run test/benchmark-put-page-latency.ts --json
+bun run test/benchmark-knowledge-runtime.ts --json
+bun run test/benchmark-graph-quality.ts --json
+bun run test/benchmark-search-quality.ts
+
+# Compare against master
+cd /path/to/gbrain-master-worktree
+# (copy benchmark-put-page-latency.ts and benchmark-knowledge-runtime.ts
+# over if they're not on master yet; they're the new scripts)
+bun run test/benchmark-put-page-latency.ts --json
+bun run test/benchmark-graph-quality.ts --json
+bun run test/benchmark-search-quality.ts
+```
+
+All four scripts run in-process against PGLite. No network, no external DB,
+no API keys. They complete in under 30 seconds combined.
+
+---
+
+## Bottom line
+
+| benchmark | moves? | direction |
+|---|---|---|
+| put_page latency | yes | +0.5ms cost for 300 free timeline entries per 200 writes |
+| time-to-queryable | yes | 0% → 100% |
+| integrity repair rate | new | n/a on master, 70/20/10 split delivered |
+| doctor completeness | new | 0% → 100% on real issues |
+| graph quality | no | unchanged, as designed |
+| search quality | no | unchanged, as designed |
+
+The branch does what it said it would do. The retrieval benchmarks stay flat
+and the ingest/repair/health benchmarks move from zero to working. That's
+the shape of a good platform change: one new dimension opens up, existing
+dimensions don't regress.

+# GBrain Knowledge Runtime — Design Doc
+
+**Status:** DRAFT for CEO review.
+**Date:** 2026-04-18.
+**Supersedes:** The earlier "Feynman Ideas Assessment + Phase A/B" plan.
+
+---
+
+## 0. Context
+
+During a CEO review of a narrow two-feature plan (bare-tweet citation repair + completeness score, borrowed from Feynman), the scope was reframed. The narrow plan duplicated work Garry's OpenClaw already does and missed the real leverage point: **the bespoke abstractions hiding inside OpenClaw — resolvers, enrichment orchestration, scheduling, deterministic output — should live in GBrain as first-class primitives.**
+
+North star: *"When Garry's OpenClaw's Claw upgrades to this version of GBrain, it should immediately recognize brilliance and completeness and say 'It's time to switch to these abstractions.'"*
+
+That is the test this document is designed against. Everything else is downstream.
+
+---
+
+## 1. The Four Layers
+
+The design is four layered abstractions. Each is independently useful; together they are the Knowledge Runtime.
+
+```

+```
+
+---
+
+## 2. Why This Order (L1 → L4)
+
+Every higher layer depends on the lower one. **L1 must land first or the rest leaks abstractions.**
+
+- **L1 (Resolvers)** is the substrate. Without a uniform lookup interface, every orchestrator + writer has bespoke callers.
+- **L2 (Orchestrator)** uses L1 to fetch; without L1 it's still ad-hoc.
+- **L3 (Scheduler)** runs L2 periodically; without L2 it's scheduling nothing structured.
+- **L4 (Output Builder)** is what every layer ultimately writes through; without it we have 14 call sites doing `fs.writeFile` with hand-rolled citation discipline.
+
+An earlier implementation could ship L1 + L4 first (the two "purest" layers) and have the most immediate integrity impact, then add L2 + L3. But the end-state must include all four.
+
+---
+
+## 3. Layer 1 — Resolver SDK
+
+### 3.1 What's broken today
+
+Garry's OpenClaw has **69 distinct external-lookup patterns** across X API (14 shapes), Perplexity, Mistral OCR, Gmail, Calendar, Slack, GitHub, YouTube, Diarize.io, YC tools, OSINT collectors, and brain-local lookups. Each one is a bespoke script under `scripts/` with its own error handling, retry logic, and output shape. GBrain has 3 ad-hoc wrappers (`embedding.ts`, `transcription.ts`, `enrichment-service.ts`) that don't share an interface.
+
+Common consequences:
+- No uniform retry/backoff strategy (some scripts retry, most don't)
+- No cost tracking (Perplexity bills eaten silently when calls return no-substance results)
+- No confidence/provenance propagation (callers can't tell if an answer is verified or inferred)
+- Users can't add a resolver without forking GBrain
+
+### 3.2 Interface
+
+```typescript
+// src/core/resolvers/interface.ts
+
+export type ResolverCost = 'free' | 'rate-limited' | 'paid';
+
+export interface ResolverRequest<I> {
+  input: I;
+  context: ResolverContext;
+  timeoutMs?: number;
+}
+
+export interface ResolverResult<O> {
+  value: O;
+  confidence: number;      // 0.0–1.0; 1.0 = deterministic from ground-truth API
+  source: string;          // e.g. "x-api-v2", "perplexity-sonar", "brain-local"
+  fetchedAt: Date;
+  costEstimate?: number;   // dollars; 0 if free
+  raw?: unknown;           // for sidecar preservation via put_raw_data
+}
+
+export interface Resolver<I, O> {
+  readonly id: string;           // stable, slug-like: "x_handle_to_tweet"
+  readonly cost: ResolverCost;
+  readonly backend: string;      // "x-api-v2", "perplexity", "brain-local"
+  readonly inputSchema: JSONSchema;
+  readonly outputSchema: JSONSchema;
+
+  available(ctx: ResolverContext): Promise<boolean>;
+  resolve(req: ResolverRequest<I>): Promise<ResolverResult<O>>;
+}
+```
+
+### 3.3 Context
+
+```typescript
+export interface ResolverContext {
+  engine: BrainEngine;
+  storage: StorageBackend;
+  config: GBrainConfig;
+  logger: Logger;
+  metrics: MetricsRecorder;
+  budget: BudgetLedger;       // hard spend caps, queried pre-resolve
+  requestId: string;
+  remote: boolean;            // trust boundary — untrusted callers get stricter validation
+  deadline?: Date;
+}
+```
+
+### 3.4 Registry + Factory (mirrors `src/core/storage.ts`)
+
+```typescript
+// src/core/resolvers/registry.ts
+export class ResolverRegistry {
+  register<I, O>(r: Resolver<I, O>): void;
+  get(id: string): Resolver<unknown, unknown>;
+  list(filter?: { cost?: ResolverCost; backend?: string }): Resolver[];
+  async resolve<I, O>(id: string, input: I, ctx: ResolverContext): Promise<ResolverResult<O>>;
+}
+
+// src/core/resolvers/factory.ts (dynamic import like engine-factory)
+export async function createResolver(
+  type: 'x-api' | 'perplexity' | 'mistral-ocr' | 'brain-local' | 'plugin',
+  config: ResolverConfig,
+): Promise<Resolver>;
+```
+
+### 3.5 Plugin format (unifies `recipes/` + `data-research` formats)
+
+A plugin is YAML + JS module, discovered via filesystem scan of `~/.gbrain/resolvers/` and `recipes/`.
+
+```yaml
+# Example: resolvers/x-api/handle-to-tweet.yaml
+id: x_handle_to_tweet
+version: 1
+category: lookup
+cost: rate-limited
+backend: x-api-v2
+module: ./handle-to-tweet.ts
+input_schema:
+  type: object
+  properties:
+    handle:   { type: string, pattern: "^[A-Za-z0-9_]{1,15}$" }
+    keywords: { type: string }
+  required: [handle]
+output_schema:
+  type: object
+  properties:
+    url:        { type: string, format: uri }
+    tweet_id:   { type: string }
+    text:       { type: string }
+    created_at: { type: string, format: date-time }
+requires:
+  env: [X_API_BEARER_TOKEN]
+health_check:
+  kind: http
+  url: https://api.twitter.com/2/tweets/1
+  expect: { status: [200, 401] }   # 401 = auth failure but endpoint reachable
+tests:
+  - input:  { handle: "garrytan" }
+    expect: { url: { pattern: "^https://x\\.com/garrytan/status/\\d+$" } }
+```
+
+Trust flagging follows the existing `src/commands/integrations.ts` pattern: only package-bundled resolvers are `embedded=true` and may run arbitrary commands; user-provided resolvers are restricted to `http` and validated schemas.
+
+### 3.6 Wraps every resolver with `FailImproveLoop`
+
+Existing `src/core/fail-improve.ts` is the deterministic-first/LLM-fallback pattern. Every resolver automatically gets wrapped: if the deterministic path (e.g. X API) returns a valid result, use it; if it fails, optionally fall back to an LLM-based resolver; log both paths for future pattern analysis and auto-test generation.
+
+### 3.7 Reference implementations to ship
+
+The OpenClaw survey inventoried 69 resolver shapes. Shipping all of them is wrong (over-scoped); shipping zero is under-scoped. The dogfood set:
+
+| # | Resolver | Purpose | Used by |
+|---|---|---|---|
+| 1 | `x_handle_to_tweet` | Bare-tweet citation repair (original Phase A) | `gbrain integrity` |
+| 2 | `url_reachable` | Dead-link detection | `gbrain integrity` |
+| 3 | `brain_slug_lookup` | Name/email → slug (wraps existing `resolveSlugs`) | Output Builder |
+| 4 | `openai_embedding` | Refactor of `src/core/embedding.ts` into Resolver | Import pipeline |
+| 5 | `perplexity_query` | Query → synthesis + citations | Enrichment Orchestrator |
+| 6 | `text_to_entities` | LLM entity extraction (structured JSON) | Enrichment Orchestrator |
+
+The remaining 63 OpenClaw patterns port incrementally, driven by user need. Each port is a new YAML + module under `recipes/` or `~/.gbrain/resolvers/` with no framework changes.
+
+---
+
+## 4. Layer 2 — Enrichment Orchestrator
+
+### 4.1 What's broken today
+
+Garry's OpenClaw's enrichment is **polished at the data layer, hacky at the control layer**:
+
+- **Completeness = "length > 500 chars + no `needs-enrichment` tag"** (`lib/enrich.mjs:351-355`). Naïve. A rich page of repetitive Perplexity summaries (see `brain/people/0interestrates.md` — 38 repeating blocks) passes this check.
+- **30-day auto-re-enrichment** runs forever. No "done" state. A person met once in 2023 still gets re-researched monthly.
+- **Cascade is convention-only.** Person→company stubs are created automatically; company→investors, company→employees traversals are documented but never implemented.
+- **No hard budget cap.** Cost is estimated per batch, never enforced across batches or per day.
+- **Failure is silent.** A bad Perplexity response logs and continues; partial writes can leave a page with a timeline entry but no raw-data sidecar.
+
+### 4.2 The orchestrator
+
+```typescript
+// src/core/enrichment/orchestrator.ts
+
+export interface EnrichmentRequest {
+  entitySlug: string;
+  trigger: 'mention' | 'stub-creation' | 'cron-sweep' | 'manual' | 'cascade';
+  tier?: 1 | 2 | 3;                // optional override; auto-computed if absent
+  cascadeDepth?: number;           // 0 = no cascade; default 1
+}
+
+export interface EnrichmentResult {
+  entitySlug: string;
+  completenessBefore: number;
+  completenessAfter: number;
+  resolversUsed: string[];         // e.g. ["perplexity_query", "x_handle_to_tweet"]
+  costSpent: number;
+  writtenTo: string[];             // page paths touched, for transaction audit
+  cascadedTo: string[];            // related entities enriched
+  status: 'enriched' | 'skipped' | 'failed' | 'budget-exhausted';
+  reason?: string;
+}
+
+export class EnrichmentOrchestrator {
+  constructor(
+    private registry: ResolverRegistry,
+    private writer: BrainWriter,
+    private budget: BudgetLedger,
+    private scorer: CompletenessScorer,
+    private graph: EntityGraph,
+  ) {}
+
+  async enrich(req: EnrichmentRequest): Promise<EnrichmentResult>;
+  async enrichBatch(reqs: EnrichmentRequest[]): Promise<EnrichmentResult[]>;
+}
+```
+
+### 4.3 Evidence-weighted completeness (replaces length heuristic)
+
+Completeness is a per-entity-type rubric, stored in frontmatter on write and recomputed on demand.
+
+```typescript
+// src/core/enrichment/completeness.ts
+export interface CompletenessRubric<Page> {
+  entityType: PageType;
+  dimensions: {
+    name: string;
+    weight: number;                // sum must = 1.0
+    check: (page: Page) => number; // 0.0–1.0
+  }[];
+}
+
+// Example rubric for persons:
+//   - has_role_and_company   0.20
+//   - has_source_urls        0.20  (≥1 URL with resolver-verified reachability)
+//   - has_timeline_entries   0.15  (≥1)
+//   - has_citations          0.15  (every claim has [Source: ...])
+//   - has_backlinks          0.10  (every linked page links back)
+//   - recency_score          0.10  (last_verified within 90 days)
+//   - non_redundancy         0.10  (no repeated blocks; distinct-lines/total-lines > 0.8)
+```
+
+**Key property:** `non_redundancy` + `recency_score` explicitly kill the two brain pathologies observed in the audit (Wilco-style repeating blocks; stale pages without `last_verified`).
+
+The `completeness` field goes in frontmatter as `0.0–1.0`. It becomes queryable via `list_pages(where: completeness < 0.5)`.
+
+### 4.4 Tier routing with hard budget
+
+Two-dimensional routing: **importance** (tier 1/2/3 from person-score) × **budget state**.
+
+```typescript
+// src/core/enrichment/tiers.ts
+export const TIER_CONFIG = {
+  1: { models: ['opus', 'sonar-deep'], maxCostUsd: 0.10, cascadeDepth: 2 },
+  2: { models: ['sonar'],              maxCostUsd: 0.02, cascadeDepth: 1 },
+  3: { models: ['sonar'],              maxCostUsd: 0.005, cascadeDepth: 0 },
+};
+
+// src/core/enrichment/budget.ts
+export class BudgetLedger {
+  // Hard caps. Queryable pre-resolve.
+  dailyCapUsd: number;
+  perEntityCapUsd: number;
+  perResolverCapUsd: Map<string, number>;
+
+  async reserve(resolverId: string, estimateUsd: number): Promise<Reservation | 'exhausted'>;
+  async commit(reservation: Reservation, actualUsd: number): Promise<void>;
+  async rollback(reservation: Reservation): Promise<void>;
+  async state(): Promise<{ spent: number; remaining: number; perResolver: Record<string, number> }>;
+}
+```
+
+**Property:** if the daily cap is reached, `orchestrator.enrich()` returns `status: 'budget-exhausted'` immediately. No silent overages. Circuit-breaker resets at midnight in the user's configured TZ.
+
+### 4.5 Cascade (entity graph traversal)
+
+```typescript
+// src/core/enrichment/cascade.ts
+export class EntityGraph {
+  // Deterministic, no LLM. Uses engine.getLinks() + engine.getBacklinks().
+  async neighbors(slug: string, depth: number): Promise<string[]>;
+  async cascadeFrom(trigger: string, depth: number): Promise<EnrichmentRequest[]>;
+}
+```
+
+If person X is enriched and gains a new `company: Acme` field, cascade checks: does `companies/acme` exist? If not, create stub + enqueue at tier 2. Does `companies/acme` link back to X? If not, write the back-link. **Iron Law is machine-enforced, not skill-enforced.**
+
+### 4.6 Fail-safe transactions
+
+Every enrichment is wrapped in a BrainWriter transaction (Layer 4). Partial writes are rolled back. No asymmetric state like timeline-entry-without-raw-sidecar.
+
+```typescript
+await writer.transaction(async (tx) => {
+  const research = await registry.resolve('perplexity_query', {...}, ctx);
+  await tx.appendTimeline(slug, {...});
+  await tx.putRawData(slug, 'perplexity', research.raw);
+  await tx.setFrontmatterField(slug, 'completeness', score);
+  // All-or-nothing commit on exit.
+});
+```
+
+---
+
+## 5. Layer 3 — Scheduler
+
+### 5.1 What's broken today
+
+Garry's OpenClaw's cron is **externally-driven JSON** (`cron/jobs.json`) with ~30 jobs manually stagger-offset at different minutes. GBrain has **zero native scheduling** — `src/commands/autopilot.ts` is a single daemon loop, and `docs/guides/cron-schedule.md` is architectural guidance, not code.
+
+Failures observed in Garry's OpenClaw's actual state:
+- `X OAuth2 Token Refresh`: 11 consecutive timeouts (critical-path silent failure)
+- `flight-tracker daily scan`: 5 consecutive timeouts
+- `morning-briefing`: 4 consecutive timeouts
+- Quiet hours are checked at runtime in skills, so a skill that forgets to check will DM at 3 a.m.
+- Staggering is manual convention; no protection against two jobs colliding after a config edit.
+
+### 5.2 ScheduledResolver interface
+
+```typescript
+// src/core/scheduling/scheduler.ts
+export interface Schedule {
+  kind: 'cron' | 'interval';
+  expr?: string;                    // cron string
+  intervalMs?: number;
+  tz: string;                       // IANA: "America/Los_Angeles"
+  quietHours?: {
+    startHour: number;              // 22 = 10 PM local
+    endHour: number;                // 7 = 7 AM local
+    policy: 'skip' | 'defer' | 'silent-run';
+  };
+  staggerKey?: string;              // jobs with same key auto-offset
+  maxConcurrent?: number;           // global concurrency cap
+  maxDurationMs?: number;           // timeout
+}
+
+export interface ScheduledResolver extends Resolver<void, ScheduledResult> {
+  schedule: Schedule;
+  retryPolicy: { maxRetries: number; backoffMs: number };
+  circuitBreaker: { failureThreshold: number; cooldownMs: number };
+  state: DurableState;              // watermark, content-hash, idempotency key
+}
+```
+
+### 5.3 Enforcement vs convention (the key delta from Garry's OpenClaw)
+
+| Concern | Garry's OpenClaw today | Knowledge Runtime |
+|---|---|---|
+| Quiet hours | Checked inside each skill (trust-based) | Enforced at scheduler, skill cannot override |
+| Staggering | Manual minute-offset in `jobs.json` | Scheduler assigns slots via hashed staggerKey |
+| Concurrency | `MAX_BATCH_PROCESSES=2` in backoff, ignored by cron | Global semaphore in scheduler |
+| Timeout | Per-job string in JSON, not always respected | Enforced via `AbortController`, timeout raises `TimeoutError` caught by orchestrator |
+| Retry | None at cron level | `retryPolicy` with exponential backoff |
+| Silent failure | "11 consecutive timeouts" unnoticed | Circuit breaker opens at threshold → escalation to user |
+| Idempotency | State files per job, no framework | `DurableState` primitive: watermark/ID/content-hash |
+
+### 5.4 Native engine + OS cron adapter
+
+The scheduler runs as either:
+1. **Embedded** (default for `gbrain autopilot`): native event loop inside the daemon process. One process, many ScheduledResolvers.
+2. **OS-driven** (for Railway/launchd/systemd): `gbrain schedule run <id>` invoked by OS cron, scheduler state is durable so cross-invocation dedup still works.
+
+Both modes share the same `Schedule` config + state.
+
+### 5.5 Observability
+
+Every scheduled run emits structured events: `started`, `skipped-quiet-hours`, `deferred-to-active-hours`, `failed-retrying`, `circuit-opened`, `completed`. Events go to:
+- `~/.gbrain/scheduler/events.jsonl` (local, always)
+- `engine.logIngest` (audit trail in brain DB)
+- Optional webhook (Slack/Telegram for the user)
+
+`gbrain doctor` reads the event log and reports: current circuit-breaker state, any resolver with > 3 consecutive failures, any resolver that hasn't fired within 3× its interval (freshness SLA like Garry's OpenClaw's `freshness-check.mjs` but built-in).
+
+---
+
+## 6. Layer 4 — Deterministic Output Builder
+
+### 6.1 The anti-hallucination invariant
+
+**Iron Law: LLM picks WHAT. Code guarantees WHERE and HOW.**
+
+Garry's OpenClaw's existing `lib/enrich.mjs:buildTweetEntry` is close to this — tweet URLs are built from `tweet.id` returned by the X API, never from LLM memory. But:
+
+- A past incident: *"Sub-agent test #2 FAILED — hallucinated 'Philip Leung' entity links across all daily files. LLM rewriting of daily files is too error-prone."* (Garry's OpenClaw memory log, 2026-04-13.)
+- Back-links depend on `appendTimeline` being called everywhere; skips are silent.
+- Slug collisions are unchecked (no conflict detection on `slugify`).
+- Citation format is post-hoc linted weekly, not pre-write enforced.
+
+### 6.2 BrainWriter
+
+```typescript

+  constructor(
+    private engine: BrainEngine,
+    private slugRegistry: SlugRegistry,

+  ) {}
+
+  async transaction<T>(fn: (tx: WriteTx) => Promise<T>): Promise<T>;

+### 6.3 Scaffolder — deterministic link + citation construction
+
+Every user-visible URL/link/citation is built by code from resolver outputs, not from LLM text.
+
+```typescript
+// src/core/output/scaffold.ts
+export class Scaffolder {
+  tweetCitation(handle: string, tweetId: string, dateISO: string): string {
+    // "[Source: [X/garrytan, 2026-04-18](https://x.com/garrytan/status/123456)]"
+  }
+  emailCitation(account: string, messageId: string, subject: string): string {
+    // deterministic Gmail URL per OpenClaw pattern
+  }
+  sourceCitation(resolverResult: ResolverResult<unknown>): string {
+    // pulls .source, .fetchedAt, .raw from the result
+  }
+  entityLink(slug: string): string {
+    // slugRegistry checks existence; returns resolvable wikilink
+  }
+}
+```
+
+### 6.4 SlugRegistry — conflict detection
+
+```typescript
+// src/core/output/slug-registry.ts
+export class SlugRegistry {
+  async create(desiredSlug: string, displayName: string, type: PageType): Promise<CreatedSlug>;
+  // Throws SlugCollision if another entity already occupies desiredSlug and isn't
+  // confirmed as the same person (via email / x_handle / disambiguator).
+  // Auto-resolves near-collisions by appending disambiguator.
+
+  async confirmSame(slugA: string, slugB: string, confidence: number): Promise<void>;
+  async merge(canonical: string, duplicate: string): Promise<void>;
+}
+```
+
+### 6.5 Pre-write validators (fail-closed for integrity)
+
+On `WriteTx.validate()` before commit:
+
+1. **Citation validator.** Every factual sentence in `compiled_truth` must have an inline `[Source: ...]` within N lines. Non-compliant paragraphs are flagged. Configurable: strict-mode rejects the transaction, lint-mode warns.
+2. **Link validator.** Every `[text](path)` must point to a page that exists OR to a URL the Scaffolder built (so it's guaranteed-valid). No raw LLM-composed URLs.
+3. **Back-link validator.** Every outbound link must have a reverse link written in the same transaction.
+4. **Triple-HR validator.** Compiled truth / timeline split enforced at the schema level.
+
+**Fails closed**: the default is strict-mode. Loosening requires explicit `writer.transaction({ strictMode: false }, ...)` and logs a warning to the ingest log.
+
+### 6.6 LLM output sanitization
+
+Any LLM output destined for a brain page passes through a JSON-Schema-validated parser first. No free-form markdown goes to disk.
+
+- Entity extraction: JSON array of `{ name, type, context }` per existing `extractEntities` pattern — strict validation.
+- Compiled-truth synthesis: LLM emits structured `{ sections: [{heading, paragraphs: [{text, sources: [...]}]}]}`, scaffolder renders to markdown.
+- Timeline entries: LLM emits `{ date, summary, detail, sources }`, scaffolder renders.
+
+LLM never sees file paths, never writes files, never emits finished markdown.
+

+
+## 7. Integration with existing GBrain
+
+### 7.1 Reuse (already polished)
+
+| Existing | Used by | Change |
+|---|---|---|
+| `src/core/fail-improve.ts` (9/10) | Wraps every Resolver in L1 | None; becomes default wrapper |
+| `src/core/backoff.ts` (9/10) | ResolverContext.backoff | None |
+| `src/core/storage.ts` (9/10) | Template for Resolver factory pattern | None; serves as pattern reference |
+| `src/core/check-resolvable.ts` (9/10) | Extend to validate Resolver plugins | Add `checkResolvers()` mode |
+| `src/commands/publish.ts` (9/10) | Uses BrainWriter under the hood | Minor: route through L4 |
+| `src/commands/backlinks.ts` (8/10) | Folded into L4 validator | Keep as CLI-facing lint entry point |
+| `src/core/operations.ts` validators | Reused in ResolverContext trust enforcement | None |
+| `src/core/engine.ts` BrainEngine (35 methods) | ResolverContext.engine | Extend with `getResolverRegistry()` |
+
+### 7.2 Replace (ad-hoc today)
+
+| Existing | Replace with |
+|---|---|
+| `src/core/enrichment-service.ts` (5/10) | `src/core/enrichment/orchestrator.ts` (L2) |
+| `src/core/embedding.ts` (monolithic) | `src/core/resolvers/builtin/embedding/openai.ts` |
+| `src/core/transcription.ts` (monolithic) | `src/core/resolvers/builtin/transcription/{groq,openai}.ts` |
+| `src/commands/integrations.ts` recipe format | Unified Resolver plugin format (§3.5) |
+| `src/core/data-research.ts` recipe format | Same unified format |
+| `src/commands/autopilot.ts` hard-coded daemon loop | Wraps a set of ScheduledResolvers |
+
+### 7.3 Extend
+
+- `src/core/engine.ts`: add `getResolverRegistry()`, `getWriter()`, `getScheduler()`. Engine becomes the runtime's root container.
+- `src/core/operations.ts`: `OperationContext` inherits from `ResolverContext` (or vice-versa). Trust flags unified.
+- `src/core/types.ts`: add `completeness: number` to `Page`, `sourcedBy: string[]` for provenance.
+
+---
+
+## 8. Migration Path (phased, shippable)
+
+Each phase ships independently, passes full E2E, is feature-flagged, and is reversible. No big-bang.
+
+### Phase 0 — Foundation (human: ~1 wk / CC: ~4 h)
+- Define `Resolver<I,O>`, `ResolverContext`, `ResolverRegistry`, `ResolverResult` (§3.2–3.4).
+- Add `src/core/resolvers/index.ts` wiring + tests for registry (register/get/list).
+- No behavioral change; ship as `v0.11.0-alpha` with feature flag.
+
+### Phase 1 — Three reference resolvers (human: ~1 wk / CC: ~4 h)
+- Port `src/core/embedding.ts` → `resolvers/builtin/embedding/openai.ts`.
+- Implement `resolvers/builtin/brain-local/slug-lookup.ts` (wraps `engine.resolveSlugs`).
+- Implement `resolvers/builtin/url-reachable.ts` (HEAD-check).
+- Prove the interface: old callers swap to `registry.resolve('openai_embedding', ...)`.
+
+### Phase 2 — BrainWriter + Slug Registry (human: ~1.5 wk / CC: ~6 h)
+- L4 core: `BrainWriter.transaction`, `Scaffolder`, `SlugRegistry` with conflict detection.
+- Pre-write validators: citation, link, back-link, triple-HR.
+- Migrate `src/commands/publish.ts` + `src/commands/backlinks.ts` to route through BrainWriter.
+- **Now** Garry's OpenClaw's "Philip Leung" hallucination is structurally impossible — LLM output passes through JSON-Schema validator before reaching Scaffolder.
+
+### Phase 3 — `gbrain integrity` command (human: ~0.5 wk / CC: ~2 h)
+- Ship the originally-scoped user-facing feature on top of the new foundation.
+- Uses Resolver SDK: `x_handle_to_tweet` + `url_reachable`.
+- Uses BrainWriter: all auto-repairs go through validated writes.
+- `--auto --confidence 0.8` mode as user approved in cherry-pick #1.
+- **User-visible value ships in Phase 3, not Phase 7.**
+
+### Phase 4 — Enrichment Orchestrator (human: ~2 wk / CC: ~8 h)
+- L2 core: `EnrichmentOrchestrator`, `BudgetLedger`, `CompletenessScorer`, `EntityGraph.cascadeFrom`.
+- Migrate `src/core/enrichment-service.ts` callers (deprecate the old file after).
+- Completeness score in frontmatter on every write (dogfooding cascades).
+
+### Phase 5 — Scheduler (human: ~2 wk / CC: ~8 h)
+- L3 core: `Scheduler`, `ScheduledResolver`, `DurableState`, circuit breaker, quiet-hours enforcer.
+- Migrate `src/commands/autopilot.ts` to a ScheduledResolver set.
+- Ship `gbrain schedule list|run|pause|tail` CLI for observability.
+
+### Phase 6 — Port 5–8 OpenClaw resolvers (human: ~1.5 wk / CC: ~6 h)
+- `perplexity_query`, `text_to_entities`, `mistral_ocr_pdf`, `x_search_all`, `x_user_to_tweets`, `gmail_query_to_threads`, `calendar_date_to_events`.
+- Each ships as YAML + TS module under `resolvers/builtin/` — **proof of the plugin format.**
+
+### Phase 7 — OpenClaw Adoption Integration (human: ~1 wk / CC: ~4 h)
+- Write `docs/openclaw/ADOPTION.md` showing your OpenClaw how to replace its 69 bespoke scripts with calls to `gbrain registry.resolve(...)`.
+- Ship a `gbrain claw-bridge` subcommand that proxies Garry's OpenClaw's current script invocations to the resolver registry — zero-edit adoption path.
+- **This is the test of the north star.** If your OpenClaw can stand up a 1-line shim and drop `scripts/x-api-client.mjs`, the abstraction succeeded.
+
+Total: human: ~10 weeks / CC: ~42 hours / calendar with single implementer: ~3–4 weeks.

+### Replaced / removed
+- `src/core/enrichment-service.ts` — folded into `enrichment/orchestrator.ts`
+- `src/core/embedding.ts` — moved into `resolvers/builtin/embedding/openai.ts`
+- `src/core/transcription.ts` — moved into `resolvers/builtin/transcription/`
+
+### Extended
+- `src/core/engine.ts` — add `getResolverRegistry()`, `getWriter()`, `getScheduler()`
+- `src/core/operations.ts` — unify with ResolverContext; every operation validator reusable by resolvers
+- `src/core/types.ts` — add `completeness: number`, `sourcedBy: string[]`, `lastVerified: Date`
+
+---
+
+## 10. Testing Strategy
+
+### Contract tests
+Every Resolver implementation tested against the interface spec. Table-driven: run the same suite against `openai_embedding`, `x_handle_to_tweet`, etc. Ensures plugin authors can't ship broken resolvers.
+
+### Property tests
+- **Idempotency:** running a ScheduledResolver twice with the same state produces the same output and doesn't double-write.
+- **Atomicity:** a BrainWriter transaction that throws mid-flight leaves the brain bit-for-bit identical to pre-transaction.
+- **Deterministic scaffolds:** given the same resolver outputs, the Scaffolder produces byte-identical citations/links.
+
+### Integration tests
+- `EnrichmentOrchestrator` end-to-end against PGLite (in-memory, no API keys) with mocked resolver registry.
+- `Scheduler` with fake clock + quiet-hours scenarios.
+- BrainWriter transaction rollback on validator failure.
+
+### Chaos tests
+- Kill the process mid-enrichment; next run must resume cleanly.
+- Simulate API timeout mid-transaction; transaction must roll back completely.
+- Corrupted state file; scheduler must escalate, not silently skip.
+
+### Regression tests vs. Garry's OpenClaw behavior
+For each OpenClaw pattern we port (e.g. X-handle → tweet URL), a regression test proves the new resolver produces the same answer on real-world inputs from the brain audit. This is the "your OpenClaw would adopt" proof.
+
+---
+
+## 11. Open Questions (flagged for CEO re-review)
+
+1. **Scope shape.** Is this the right four-layer decomposition, or are some layers better left to OpenClaw (e.g. Scheduling lives above GBrain, not in it)?
+2. **Phase 3 user-value break.** Does Phase 3 (user-visible `gbrain integrity`) ship early enough, or do we need an even smaller MVP?
+3. **LLM-as-resolver.** Should `text_to_entities` be a Resolver, or does that blur the "code vs LLM" line the invariant relies on?
+4. **Plugin format.** YAML + TS module (§3.5) vs. pure TS module with decorator-style metadata. Latter is more type-safe; former is more discoverable.
+5. **Cross-resolver transactions.** Do we support "atomic fetch-from-Perplexity + write-to-brain" at the L2 layer? Current design says yes; implementation is tricky (Perplexity call isn't rollbackable).
+6. **OpenClaw bridge scope.** Phase 7 `gbrain claw-bridge` — is that worth a phase of its own, or should adoption be documentation-only?
+7. **Completeness rubric coverage.** Do we define rubrics for all 9 PageTypes upfront, or ship people/company/meeting first and extend incrementally?
+8. **Budget config UX.** Hard daily cap is strict; should we also expose a soft-cap warning mode, and how is the cap set (env var? config file? prompt on first use?)
+9. **Backwards compat.** `src/commands/publish.ts` and `src/commands/backlinks.ts` have been running cleanly for weeks. Refactoring through BrainWriter carries migration risk. Acceptable?
+10. **Existing TODOS alignment.** `TODOS.md` has P0 "Runtime MCP access control" and P2 security hardening. The new RuntimeContext.remote flag interacts with both — do we fold MCP access control into Phase 0 or keep separate?
+
+---
+
+## 12. Verification (the "your OpenClaw would adopt" test)
+
+The design succeeds iff:
+
+- [ ] A user can add a new resolver by dropping a YAML + TS module in `~/.gbrain/resolvers/` without editing GBrain source.
+- [ ] Your OpenClaw can delete `scripts/x-api-client.mjs` and replace all callers with 1-line `await registry.resolve('x_handle_to_tweet', ...)`.
+- [ ] No brain page can be written with a bare tweet reference, a missing back-link, or an unverified URL (validators catch it pre-commit).
+- [ ] Running `gbrain integrity --auto --confidence 0.8` over a real brain fixes ≥1,000 of the 1,424 known bare-tweet citations without human review.
+- [ ] Full E2E test suite passes on both PGLite + Postgres engines.
+- [ ] The Knowledge Runtime ships across 7 phases with each phase individually shippable and reversible.

+# Minions Worker Deployment Guide
+
+Deploy `gbrain jobs work` so it stays running across crashes, reboots, and
+Postgres connection blips. Written for agents to execute line-by-line.
+
+## The problem
+
+The persistent worker can die silently from:
+
+- Database connection drops (Supabase/Postgres maintenance or network blips).
+- Lock-renewal failures → the stall detector eventually dead-letters jobs.
+- Bun process crashes with no automatic restart.
+- Internal event-loop death (PID alive, worker loop stopped).
+
+When the worker dies, submitted jobs sit in `waiting` forever. Nothing in
+gbrain core auto-restarts the worker — that's what this guide wires up.
+
+## Variables used in this guide
+
+Substitute these once before copy-pasting any snippet.

+| Variable | Meaning | Typical value |
+|---|---|---|
+| `$GBRAIN_BIN` | Absolute path to the `gbrain` binary | `$(command -v gbrain)` — often `/usr/local/bin/gbrain` or `~/.bun/bin/gbrain` |
+| `$GBRAIN_WORKER_USER` | OS user that owns the worker process | the same user that ran `gbrain init`; never `root` |
+| `$GBRAIN_WORKER_PID_FILE` | Worker PID + restart-epoch file | `/tmp/gbrain-worker.pid` (or `/var/run/gbrain/worker.pid` for systemd) |
+| `$GBRAIN_WORKER_LOG_FILE` | Worker log sink (stdout + stderr merged) | `/tmp/gbrain-worker.log` (or `/var/log/gbrain/worker.log`) |
+| `$GBRAIN_WORKSPACE` | `cwd` for shell jobs submitted by this deployment | absolute path, e.g. `/srv/my-brain` |
+| `$GBRAIN_ENV_FILE` | Secrets file sourced by crontab / systemd | `/etc/gbrain.env` (mode 600) |
+
+## Preconditions
+
+Run these before Step 1 of any option. Fail fast if something is wrong.
+
+```bash
+# 1. gbrain is on PATH and resolves to an absolute location.
+command -v gbrain || { echo "gbrain not on PATH. Install, then retry."; exit 1; }
+
+# 2. DATABASE_URL points at reachable Postgres (or PGLite path exists).
+gbrain doctor --fast --json | jq '.checks[] | select(.name=="db_connectivity")'
+
+# 3. Schema is up to date. If version=0 or status=="fail", fix it first:
+#    gbrain apply-migrations --yes
+gbrain doctor --fast --json | jq '.checks[] | select(.name=="schema_version")'
+
+# 4. You have write access to at least one crontab mechanism.
+crontab -l >/dev/null 2>&1 && echo "user crontab OK"
+[ -w /etc/crontab ] && echo "/etc/crontab OK"
+
+# 5. If you plan to submit `shell` jobs, the WORKER process needs
+#    GBRAIN_ALLOW_SHELL_JOBS=1 (submitters do not). The handler is gated
+#    in registerBuiltinHandlers(); without the flag the worker startup
+#    line reads "shell handler disabled (...)".
+```
+
+## Which option?
+
+- Your workload runs LLM subagents (`gbrain agent run`) or jobs that take
+  > 30 s → **Option 1** (watchdog cron + persistent worker).
+- Your workload is short deterministic scripts on a fixed schedule (every
+  3 h, daily, weekly) → **Option 2** (inline `--follow`).
+- You don't have shell access to a long-running box (Fly/Render/Railway,
+  or any systemd host) → **Option 3** (service manager — replaces cron).
+
+## Option 1: watchdog cron + persistent worker
+
+A 5-minute cron checks whether the worker process is alive **and** whether
+it has logged an internal shutdown since its last start. Restarts if either
+condition fails.
+
+### 1a. Install the env file (secrets stay out of crontab)
+
+Never paste `DATABASE_URL` or API keys into crontab. `/etc/crontab` is
+mode 644 (world-readable); user crontabs under `/var/spool/cron/` are
+readable by `root`. Use the shipped env-file template:
+
+```bash
+sudo install -m 600 -o $GBRAIN_WORKER_USER -g $GBRAIN_WORKER_USER \
+  docs/guides/minions-deployment-snippets/gbrain.env.example /etc/gbrain.env
+sudoedit /etc/gbrain.env
+```
+
+Fill in the connection string and `GBRAIN_ALLOW_SHELL_JOBS=1` (if
+applicable). See
+[`gbrain.env.example`](./minions-deployment-snippets/gbrain.env.example)
+for the full list.
+
+### 1b. Install the watchdog script
+
+The [`minion-watchdog.sh`](./minions-deployment-snippets/minion-watchdog.sh)
+ships in-repo and writes a two-line PID file (PID on line 1, restart epoch
+on line 2). The restart-epoch marker is how the watchdog distinguishes
+stale shutdown lines in the log from current ones — without it, every tick
+after the first restart would match an old `worker shutting down` line and
+loop forever.
+
+Requires GNU coreutils (Linux default). On macOS/BSD install via
+`brew install coreutils` and alias `date` to `gdate` in the cron env if you
+want to test the watchdog locally; production Linux boxes work as-is.
+
+```bash
+sudo install -m 755 -o $GBRAIN_WORKER_USER -g $GBRAIN_WORKER_USER \
+  docs/guides/minions-deployment-snippets/minion-watchdog.sh \
+  /usr/local/bin/minion-watchdog.sh
+```
+
+### 1c. Wire into cron
+
+Pick the form that matches the crontab you're editing.
+
+**If you ran `crontab -e`** (user crontab — 5-field, no user column):
+
+```
+SHELL=/bin/bash
+PATH=/usr/local/bin:/usr/bin:/bin
+BASH_ENV=/etc/gbrain.env
+*/5 * * * * /usr/local/bin/minion-watchdog.sh
+```
+
+**If you edited `/etc/crontab` directly** (system crontab — 6-field, with
+user column):
+
+```
+SHELL=/bin/bash
+PATH=/usr/local/bin:/usr/bin:/bin
+BASH_ENV=/etc/gbrain.env
+*/5 * * * * gbrain /usr/local/bin/minion-watchdog.sh
+```
+
+In both forms, `BASH_ENV=/etc/gbrain.env` tells non-interactive bash to
+source the env file before running the watchdog — that's how the
+connection string and `GBRAIN_ALLOW_SHELL_JOBS` reach the worker without
+landing in the world-readable crontab itself.
+
+### 1d. Log rotation
+
+The watchdog appends to the worker log across restarts. If you expect the
+file to grow unbounded, rotate it externally with `logrotate`:
+
+```
+# /etc/logrotate.d/gbrain-worker
+/tmp/gbrain-worker.log {
+  daily
+  rotate 7
+  missingok
+  notifempty
+  copytruncate
+}
+```
+
+`copytruncate` is important — the watchdog's restart-epoch check survives
+it (the epoch is compared against in-log timestamps, not file inode).
+
+## Option 2: inline `--follow` (no persistent worker)
+
+Each cron run brings its own temporary worker. `--follow` starts one on
+the queue and blocks until the just-submitted job reaches a terminal state
+(`completed` / `failed` / `dead` / `cancelled`). 2-3 s startup overhead
+per job; negligible vs job duration for scheduled work.
+
+Example: nightly brain enrichment as a shell job.
+
+```bash
+GBRAIN_ALLOW_SHELL_JOBS=1 gbrain jobs submit shell \
+  --queue nightly-enrich \
+  --params "{\"cmd\":\"$GBRAIN_BIN embed --stale\",\"cwd\":\"$GBRAIN_WORKSPACE\"}" \
+  --follow \
+  --timeout-ms 600000
+```
+
+Replace `gbrain embed --stale` with whichever gbrain subcommand you're
+scheduling (`sync`, `extract`, `orphans`, `doctor`, `check-backlinks`,
+`lint`, `autopilot`). If you're shelling out to a non-gbrain binary,
+keep its absolute path in the `cmd`.
+
+**Shared-queue gotcha.** If other jobs are already waiting on the same
+queue with higher priority or earlier `created_at`, the temporary worker
+processes those first before reaching yours. `--follow` still exits only
+when YOUR job finishes. For strict single-job semantics on shared queues,
+use a dedicated queue name like `nightly-enrich` above.
+
+## Option 3: service manager (systemd / Fly / Render / Railway)
+
+Replaces the watchdog entirely. No cron, no PID file, no restart-loop.
+The service manager owns liveness.
+
+### systemd (Linux hosts with shell access)
+
+```bash
+# Create the worker user if it doesn't exist.
+sudo useradd --system --home "$GBRAIN_WORKSPACE" --shell /usr/sbin/nologin gbrain \
+  2>/dev/null || true
+sudo mkdir -p "$GBRAIN_WORKSPACE" && sudo chown gbrain:gbrain "$GBRAIN_WORKSPACE"
+
+# Install the unit file, substituting /srv/gbrain → your workspace path.
+sudo install -m 644 docs/guides/minions-deployment-snippets/systemd.service \
+  /etc/systemd/system/gbrain-worker.service
+sudo sed -i "s|/srv/gbrain|$GBRAIN_WORKSPACE|g" \
+  /etc/systemd/system/gbrain-worker.service
+
+# See 1a above for /etc/gbrain.env install.
+sudo systemctl daemon-reload
+sudo systemctl enable --now gbrain-worker
+sudo systemctl status gbrain-worker
+journalctl -u gbrain-worker -n 50
+```
+
+`Restart=always` + `RestartSec=10s` give you crash-loop recovery. The unit
+runs as an unprivileged `gbrain` user with `PrivateTmp`, `ProtectSystem=strict`,
+and `ReadWritePaths=$GBRAIN_WORKSPACE`. `LimitNOFILE=65535` in the shipped
+unit covers Bun + Postgres pool + concurrent LLM subagent calls without
+hitting the default 1024 cap.
+
+### Fly.io
+
+Merge the `[processes]` block from
+[`fly.toml.partial`](./minions-deployment-snippets/fly.toml.partial) into
+your existing `fly.toml`. Set secrets with `fly secrets set` —
+Fly auto-restarts the process on crash.
+
+### Render / Railway / Heroku
+
+Drop [`Procfile`](./minions-deployment-snippets/Procfile) at the repo root.
+Set the connection string and `GBRAIN_ALLOW_SHELL_JOBS=1` via the
+platform's env UI or CLI.
+
+## Upgrading an existing deployment
+
+If you deployed on v0.13.x or earlier, walk this checklist:
+
+1. **Stop the worker before upgrading.**
+   `kill $(head -n1 /tmp/gbrain-worker.pid)` and wait for the process to
+   exit. Skipping this risks an in-flight job landing partial schema.
+2. **Run `gbrain upgrade`**. Then `gbrain apply-migrations --yes` if
+   `gbrain doctor` reports any migration as `partial` or `pending`.
+3. **If you run shell jobs:** from v0.14 onward, the worker requires
+   `GBRAIN_ALLOW_SHELL_JOBS=1` to register the `shell` handler. Add it to
+   `/etc/gbrain.env`. Submitters don't need the flag; only the worker does.
+4. **If you tuned your watchdog for `max_stalled=1`:** v0.14.3 migration
+   v15 raised the schema default to 5 and backfilled existing non-terminal
+   rows. A watchdog tuned around 1-strike dead-lettering will now
+   over-restart because it takes 5 misses to dead-letter. Switch to the
+   shipped watchdog (which keys on log markers, not job state).
+5. **If your v0.16.1 watchdog is still running:** it has a restart-loop
+   bug (old shutdown lines in the unrotated log re-match every 5 min
+   forever). Install the current `minion-watchdog.sh` from this guide's
+   snippets — it writes a restart epoch into the PID file and only
+   considers log lines newer than that epoch.
+6. **Verify.** `gbrain doctor` should report zero `pending` or `partial`
+   migrations. `gbrain jobs stats` should show no unexplained growth in
+   `dead` between pre- and post-upgrade.
+
+## Known issues
+
+### Supabase connection drops
+
+The worker uses a single Postgres connection. If Supabase drops it
+(maintenance, connection limits, network blip), lock renewal fails
+silently. The stall detector then dead-letters the job after
+`max_stalled` misses.
+
+**Current defaults that make this worse:**
+
+- `lockDuration: 30000` (30 s) — too short for long jobs during connection blips.
+- `max_stalled: 5` (schema column default on master — see `src/schema.sql`
+  and `src/core/pglite-schema.ts`). Five missed heartbeats before dead-letter.
+- `stalledInterval: 30000` (30 s) — checks too aggressively.
+
+**Tune per-job today.** `gbrain jobs submit` accepts `--max-stalled N`,
+`--backoff-type fixed|exponential`, `--backoff-delay <ms>`,
+`--backoff-jitter 0..1`, and `--timeout-ms N` as first-class flags
+(since v0.13.1). These write onto the job row at submit time — which is
+what `handleStalled()` reads — so per-job tuning is the real knob today.
+Worker-level `--lock-duration` / `--stall-interval` are on the roadmap;
+until they land, rely on per-job `--max-stalled` plus the watchdog (or
+systemd) for worker health.
+
+### DO NOT pass `maxStalledCount` to `MinionWorker`
+
+It's a no-op. The stall detector reads the row's `max_stalled` column
+(set at submit time), not the worker opt in `src/core/minions/worker.ts:74`.
+Use `gbrain jobs submit --max-stalled N` per-job instead.
+
+### Zombie shell children
+
+When the Bun worker crashes hard, child processes from shell jobs can
+become zombies. The watchdog's 10 s `SIGTERM → SIGKILL` window covers the
+shell handler's 5 s child-kill grace (`KILL_GRACE_MS`). For long-running
+shell jobs, bump the watchdog's `sleep 10` to `sleep 30` so the worker
+has time to flush in-flight jobs before the kill.
+
+## Smoke test
+
+```bash
+# Worker alive?
+kill -0 $(head -n1 /tmp/gbrain-worker.pid) 2>/dev/null && echo ALIVE || echo DEAD
+
+# Aggregate queue health.
+gbrain jobs stats
+
+# Jobs currently stalled (still `active` with expired lock_until, pre-requeue).
+gbrain jobs list --status active --limit 10
+
+# Dead-lettered jobs.
+gbrain jobs list --status dead --limit 10
+
+# Shell handler registered? (stderr banner merged into log via 2>&1.)
+grep "shell handler enabled" /tmp/gbrain-worker.log
+```
+
+## Uninstall
+
+- **Option 1 (watchdog cron):** `crontab -e`, delete the watchdog line.
+  `kill $(head -n1 /tmp/gbrain-worker.pid) && rm /tmp/gbrain-worker.pid`.
+  Optionally `sudo rm /etc/gbrain.env /usr/local/bin/minion-watchdog.sh`.
+- **Option 2 (inline `--follow`):** remove the cron entry. Nothing else to
+  clean up — temporary workers exit with their jobs.
+- **Option 3 (systemd):** `sudo systemctl disable --now gbrain-worker`,
+  then `sudo rm /etc/systemd/system/gbrain-worker.service /etc/gbrain.env`,
+  then `sudo systemctl daemon-reload`.
+- **Option 3 (Fly/Render/Railway):** delete the `worker` process from
+  `fly.toml` / `Procfile` and redeploy. Secrets set via `fly secrets`
+  persist until `fly secrets unset`.

+
+```bash
+# Run your first shell job:
+GBRAIN_ALLOW_SHELL_JOBS=1 gbrain jobs submit shell \
+  --params '{"cmd":"echo hello","cwd":"/tmp"}' --follow
+# → exit_code: 0, stdout_tail: "hello\n", duration_ms: 43
+```
+
+That's it. Your cron scripts now have a home with retry, backoff, DLQ, and
+`gbrain jobs list` visibility, without each one booting a full LLM session.
+
+**PGLite users:** `gbrain jobs work` does not run on PGLite (exclusive file
+lock). Every crontab invocation must use `--follow` for inline execution.
+Postgres users can run a persistent worker; see recipes below.
+
+---
+
+## Why it exists
+
+If your agent runs deterministic scripts from cron (token refresh, API fetch,
+scrape + write), each one pays the cost of a full LLM session on the gateway.
+Fourteen simultaneous fires on a Series A deployment pin CPU at 100% and block
+live messages. None of those scripts need reasoning. They need a shell.
+
+Shell jobs move them to the Minions worker: one deterministic-script execution
+per cron, zero LLM tokens, unified visibility and retry.
+
+---
+
+## Security model (read this)
+
+Shell exec is a large blast radius. We ship two independent gates, both must
+pass:
+
+1. **MCP boundary.** `submit_job` with `name: 'shell'` is rejected when
+   `ctx.remote === true` (MCP callers). Independent of the env flag. Remote
+   agents can never submit shell jobs. `MinionQueue.add('shell', ...)` has its
+   own guard too, so an in-process handler can't programmatically bypass this.
+2. **Env flag.** The worker only registers the shell handler when
+   `GBRAIN_ALLOW_SHELL_JOBS=1` is set on the worker process. Default: off. Your
+   agent opts in per-host.
+
+**What the env allowlist does AND does not do.** Shell jobs run with a minimal
+env: `PATH, HOME, USER, LANG, TZ, NODE_ENV`. Your secrets like `OPENAI_API_KEY`
+and `DATABASE_URL` are NOT passed to the child. You opt-in additional keys per
+job via `env: { ... }`. This stops accidental `$OPENAI_API_KEY` interpolation in
+a user-authored script. It does **not** sandbox filesystem reads: a shell
+script can `cat ~/.env` or any file the worker process can read. The operator
+picks a safe `cwd`. That is the trust boundary.
+
+**Audit trail, not forensic insurance.** Every submission writes a JSONL line
+to `~/.gbrain/audit/shell-jobs-YYYY-Www.jsonl` (ISO-week rotation; override
+with `GBRAIN_AUDIT_DIR`). Failures log to stderr and don't block submission, so
+a disk-full adversary could silently disable the trail. Good for "what did
+this cron submit last Tuesday", not for security-critical forensics.
+
+**The command text is logged as-is.** If you embed a secret in `cmd`
+(`curl -H 'Authorization: Bearer ...'`), it shows up in the audit file. Put
+secrets in `env:` instead.
+
+---
+
+## Migrate a cron
+
+### Postgres worker (recommended)
+
+On one terminal, start a persistent worker:
+
+```bash
+GBRAIN_ALLOW_SHELL_JOBS=1 gbrain jobs work
+```
+
+Rewrite crontab to submit shell jobs (no `--follow`):
+
+```cron
+# Before (LLM gateway):
+#   OpenClaw cron: x-garrytan-unified
+# After (Minions worker):
+3 13,16,19,22,1,4,7,10 * * * \
+  gbrain jobs submit shell \
+    --params '{"cmd":"node scripts/x-garrytan-daily.mjs","cwd":"/data/.openclaw/workspace"}' \
+    --max-attempts 3 --timeout-ms 300000
+```
+
+Worker claims the job on next poll, runs it, records `exit_code` +
+`stdout_tail` + `stderr_tail` in the result. Failures retry per
+`--max-attempts` with exponential backoff.
+
+### PGLite (inline execution)
+
+PGLite doesn't support the persistent worker daemon. Every crontab invocation
+uses `--follow` to run inline:
+
+```cron
+# Each cron tick spawns a short-lived worker that runs the job inline.
+3 13,16,19,22,1,4,7,10 * * * \
+  GBRAIN_ALLOW_SHELL_JOBS=1 gbrain jobs submit shell \
+    --params '{"cmd":"node scripts/x-garrytan-daily.mjs","cwd":"/data/.openclaw/workspace"}' \
+    --follow --timeout-ms 300000
+```
+
+Note: `--follow` blocks the crontab slot until the job finishes. If 14 shell
+crons land at the same minute and each takes 30s, they serialize through
+crontab's spawning limits. Postgres + persistent worker scales better.
+
+### Submitting with `argv` (no shell interpolation)
+
+For programmatic callers assembling commands from JSON, use `argv` instead of
+`cmd`. No shell, no injection surface:
+
+```bash
+gbrain jobs submit shell \
+  --params '{"argv":["node","scripts/fetch.mjs","--date","2026-04-19"],"cwd":"/data"}' \
+  --follow
+```
+
+---
+
+## Debug a failed job
+
+```bash
+# List dead shell jobs
+gbrain jobs list --status dead
+
+# Inspect one
+gbrain jobs get 42
+# → error_text, stacktrace, result.stdout_tail, result.stderr_tail
+
+# Submission audit log (operator trail, not forensic)
+cat ~/.gbrain/audit/shell-jobs-*.jsonl | jq '.'
+
+# First-time failure mode: submitted without env flag on the worker
+gbrain jobs list --status waiting --name shell
+# If rows pile up here, no worker with GBRAIN_ALLOW_SHELL_JOBS=1 is running.
+```
+
+---
+
+## Limitations
+
+- **Filesystem reads are not sandboxed.** See "Security model" above. Don't
+  point `cwd` at a directory full of secrets.
+- **Audit log is advisory.** Disk-full or EACCES silently disables it.
+- **Cancel latency is lock-renewal-bounded** (~7-15 s by default). A cancelled
+  child keeps running until the next lock-renewal tick fails.
+- **`--follow` claim order** is by priority/created_at. If another job is
+  waiting in the same queue at the time of `--follow`, that one runs first.
+- **`cwd` symlink TOCTOU.** The absolute-path check doesn't guard against
+  symlinks pointing elsewhere at execution time. Operator-scope concern.

+# Multi-source brains
+
+**A single gbrain database can hold multiple knowledge repos.** Each one
+is a `source`: a logical brain-within-the-brain with its own slug
+namespace, its own sync state, and its own federation policy. The rest
+of this guide walks the three canonical scenarios.
+
+## The three scenarios
+
+### 1. Unified knowledge recall (wiki + gstack)
+
+You have a personal wiki and a `gstack` checkout. Both belong to you,
+both are knowledge you want your agent to recall across. When you ask
+"what did I learn about X?" you want the best hit whether it lives in
+the wiki or in a gstack plan.
+
+```bash
+# Register the gstack source, federate so it joins cross-source search
+gbrain sources add gstack --path ~/.gstack --federated
+
+# Pin the directory so `gbrain sync` knows which source it's walking
+cd ~/.gstack && gbrain sources attach gstack
+
+# Initial sync
+gbrain sync --source gstack
+
+# Now `gbrain search "retry budgets"` returns hits from BOTH wiki and
+# gstack. Each result includes source_id so the agent can cite properly.
+```
+
+Result: wiki pages and gstack plans are separate (different source_ids,
+different slug namespaces) but share the search surface.
+
+### 2. Purpose-separated brains (yc-media + garrys-list)
+
+You run two completely different content pipelines on the same backend.
+YC Media covers portfolio news and founder profiles. Garry's List is
+personal writing. You explicitly DON'T want them mixed in search — YC
+portfolio content leaking into essay searches is a bug, not a feature.
+
+```bash
+# Two sources, both isolated (federated=false)
+gbrain sources add yc-media --path ~/yc-media --no-federated
+gbrain sources add garrys-list --path ~/writing --no-federated
+
+# Pin each checkout directory
+(cd ~/yc-media && gbrain sources attach yc-media)
+(cd ~/writing && gbrain sources attach garrys-list)
+
+# Sync each independently
+gbrain sync --source yc-media
+gbrain sync --source garrys-list
+```
+
+Result: searching from neither directory returns the `default` source
+(your main brain). Searching from inside `~/yc-media` returns only yc-
+media hits. Searching from inside `~/writing` returns only garrys-list.
+Federation is opt-in, not leaked.
+
+To search across them explicitly on demand:
+
+```bash
+gbrain search "tech layoffs" --source yc-media,garrys-list
+```
+
+### 3. Mixed (wiki federated + sessions isolated)
+
+Your main wiki is federated with a few trusted sources. Your session
+transcripts (coming in v0.18) land in a separate isolated source so
+they don't dominate every search result.
+
+```bash
+# Federated sources
+gbrain sources add gstack --path ~/.gstack --federated
+
+# Isolated source (future v0.18 — sessions use this shape today for ingest)
+gbrain sources add sessions --path ~/.claude/sessions --no-federated
+```
+
+## Resolution priority
+
+When any command needs to pick a source, gbrain walks this list (highest
+first):
+
+1. Explicit `--source <id>` flag.
+2. `GBRAIN_SOURCE` environment variable.
+3. `.gbrain-source` dotfile in CWD or any ancestor directory.
+4. A registered source whose `local_path` contains the CWD (longest
+   prefix wins for nested checkouts).
+5. The brain-level default set via `gbrain sources default <id>`.
+6. The seeded `default` source.
+
+So inside `~/.gstack/plans/` on a brain that pinned `gstack` to
+`~/.gstack` via `.gbrain-source`, `gbrain put-page` implicitly writes to
+the `gstack` source. Outside any registered directory with no env/dotfile
+set, it writes to the default.
+
+## Federation flag
+
+Every source row stores `config.federated: boolean` in its JSONB config.
+
+| Value | Meaning |
+|-------|---------|
+| `true` | Source participates in unqualified `gbrain search "X"` results. |
+| `false` (default for new sources) | Source only searched when explicitly named via `--source <id>` or qualified citation. |
+
+The seeded `default` source is `federated=true` so pre-v0.17 brains
+behave exactly as before — every page appears in search.
+
+Flip later with `gbrain sources federate <id>` / `unfederate <id>`.
+
+## Commands
+
+Full subcommand reference:
+
+```
+gbrain sources add <id> --path <p> [--name <n>] [--federated|--no-federated]
+                               Register a source. id: [a-z0-9](?:[a-z0-9-]{0,30}[a-z0-9])?
+gbrain sources list [--json]   List all sources with page counts + federation state.
+gbrain sources remove <id> [--yes] [--dry-run] [--keep-storage]
+                               Cascade-delete a source (pages, chunks, timeline).
+gbrain sources rename <id> <new-name>
+                               Change display name only; id is immutable.
+gbrain sources default <id>    Set the brain-level default.
+gbrain sources attach <id>     Write .gbrain-source in CWD (like kubectl context).
+gbrain sources detach          Remove .gbrain-source from CWD.
+gbrain sources federate <id>
+gbrain sources unfederate <id>
+```
+
+## Citation format for agents
+
+When agents receive multi-source results they MUST cite pages in
+`[source-id:slug]` form. Example:
+
+> You told me about the distillation protocol — see [wiki:topics/ai]
+> and [gstack:plans/multi-repo] for where this came from.
+
+The citation key is `sources.id` (immutable). Renaming a source via
+`gbrain sources rename` changes the display name only; existing
+citations keep working.
+
+## Writing to a specific source
+
+```bash
+# Pass --source explicitly
+gbrain put-page topics/ai ... --source wiki
+
+# Or rely on the dotfile / env / CWD match
+cd ~/.gstack && gbrain put-page plans/multi-repo ...
+# → source auto-resolves to gstack
+```
+
+Reads span federated sources by default. Writes require a resolved
+source (explicit, inferred, or default). The resolver never picks a
+source silently when ambiguous — it errors with a clear fix.
+
+## Upgrading an existing brain
+
+`gbrain upgrade` runs the v16 + v17 migrations automatically. Your
+existing pages all move under `source_id='default'`. Behavior is
+unchanged until you add a second source.
+
+To add one:
+
+```bash
+gbrain sources add gstack --path ~/.gstack --federated
+cd ~/.gstack && gbrain sources attach gstack && gbrain sync
+```
+
+Two commands. The existing default source is untouched.
+
+## Not in v0.18.0
+
+- Session transcript ingest (`.jsonl`, raised size cap, session
+  PageType) — v0.18.
+- Per-source retention/TTL (`gbrain sources prune`) — v0.18.
+- ACL enforcement via caller-identity — v0.17.1.
+- `gbrain sources import-from-github <url>` one-shot bootstrap — patch
+  release after the core plumbing stabilizes.
+
+All of these build on the `sources` primitive shipped here.

+# Plugin authors guide (v0.15)
+
+`gbrain` discovers subagent definitions from outside this repo via
+`GBRAIN_PLUGIN_PATH`. If you maintain a downstream agent (your OpenClaw
+deployment, a workflow host, a private tool) and want to ship custom
+subagents alongside it, drop a plugin directory on that env path.
+
+This guide is for plugin authors. The CLI user doesn't need to read it.
+
+## Minimum viable plugin
+
+```
+/path/to/my-plugin/
+├── gbrain.plugin.json
+└── subagents/
+    └── my-summarizer.md
+```
+

+
+```json
+{
+  "name": "my-plugin",
+  "version": "1.0.0",
+  "plugin_version": "gbrain-plugin-v1"
+}
+```

+allowed_tools:
+  - brain_search
+  - brain_get_page
+---
+
+You are a brain page summarizer. Given a slug, fetch the page and produce
+a 3-sentence summary.
+```
+
+## Turning it on
+
+```bash
+export GBRAIN_PLUGIN_PATH="/path/to/my-plugin"
+gbrain jobs work           # worker startup prints the plugin load line
+gbrain agent run "summarize meetings/2026-04-20" --subagent-def my-summarizer
+```
+
+Multiple plugins: colon-separated, just like `$PATH`.
+
+```bash
+export GBRAIN_PLUGIN_PATH="/path/to/plugin-a:/path/to/plugin-b"
+```
+
+## Rules (strict by design)
+
+**Path policy.** Absolute paths only. Relative paths, `~`-prefixed paths,
+and URL-style paths (`https://`, `file://`) are rejected with a warning.
+You control where your plugin lives on disk; `gbrain` doesn't guess.
+
+**Collision policy.** If two plugins ship a subagent with the same `name`,
+the one listed FIRST in `GBRAIN_PLUGIN_PATH` wins. The other is dropped
+with a warning naming both sources.
+
+**Trust policy.** Plugins ship subagent definitions ONLY in v0.15:
+
+- You **cannot** declare new tools.
+- You **cannot** extend the brain tool allow-list.
+- You **cannot** override any `agentSafe` or similar flag.
+- Your `allowed_tools:` frontmatter field MUST subset the derived brain
+  tool registry. Names not in the registry are rejected at plugin load
+  time (worker startup), NOT at subagent dispatch time — so a typo in
+  your plugin gives you a loud startup error, not a silent "tool never
+  fires" at 3am.
+
+v0.16+ may open up plugin-declared tools with a separate contract. Don't
+expect it.
+
+## `gbrain.plugin.json`
+
+| field            | type   | required | notes                                                              |

+|-----------------|----------|----------|-----------------------------------------------------------------------------------------|
+| `name`          | string   | no       | Subagent identifier used as `--subagent-def`. Defaults to the file basename.            |
+| `model`         | string   | no       | Anthropic model id. Defaults to the handler default (sonnet).                           |
+| `max_turns`     | number   | no       | Cap on assistant turns. Defaults to 20.                                                 |
+| `allowed_tools` | string[] | no       | Whitelist of tool names. Must subset the derived brain registry. Rejected on mismatch.  |
+
+Unknown frontmatter fields are preserved but ignored by the handler. v0.16
+may consume more of them.
+
+## Caveats that will bite you
+
+1. **Plugin definitions can't change during a run.** The loader reads the
+   disk once at worker startup. Editing a subagent def doesn't re-take
+   effect until you restart the worker. This is deliberate — live
+   reloads would break crash-resumable replay.
+
+2. **`~/.gbrain/audit/subagent-jobs-*.jsonl` is local only.** If your
+   worker runs on a different host than the `gbrain agent logs` caller,
+   the CLI won't see heartbeats from that worker. v0.16 will unify this;
+   for now assume worker + CLI share a filesystem.
+
+3. **Tool calls always run with `ctx.remote = true`.** Even on local CLI
+   invocation. Tools that gate on `remote=true` (file_upload's strict
+   confinement, put_page's namespace check) will apply. Good default; a
+   subagent definition that wants local-filesystem reach beyond the brain
+   can't have it.
+
+4. **`put_page` writes are namespace-scoped.** A subagent with id 42 can
+   only write under `wiki/agents/42/...`. This is enforced both in the
+   tool schema (the slug pattern shown to the model) AND server-side in
+   the `put_page` operation (fail-closed if `viaSubagent=true`). Don't
+   try to route around it; you'll get `permission_denied`.

+# Progress events
+
+Canonical reference for the JSONL progress stream that `gbrain` writes to
+`stderr` when a bulk command runs with `--progress-json`. Stable from
+v0.15.2. Additive changes only; no renames or removals without a major
+version bump.
+
+Most humans won't read this page. Agents parsing progress will.
+
+## When do I get these events?
+
+Any of these commands stream events when `--progress-json` is set:
+
+- `gbrain doctor` (DB checks, JSONB integrity, markdown body completeness,
+  integrity sample)
+- `gbrain orphans`
+- `gbrain embed`
+- `gbrain files sync`
+- `gbrain export`
+- `gbrain extract [links|timeline|all]` (fs or db source)
+- `gbrain import`
+- `gbrain sync`
+- `gbrain migrate --to …`
+- `gbrain repair-jsonb`
+- `gbrain check-backlinks`
+- `gbrain lint`
+- `gbrain integrity auto`
+- `gbrain eval`
+- `gbrain apply-migrations` (the orchestrator + every child command)
+
+Non-bulk commands (`stats`, `graph-query`, `get`, `put`, etc.) don't emit
+events — they return in under a second.
+
+## Channel
+
+- Progress events: **`stderr`**, one JSON object per line, `\n`-terminated.
+- Data results (`--json` payloads from each command): **`stdout`**.
+- Final human summaries: **`stdout`**.
+
+Agents can safely capture stdout for their result parsing and read stderr
+separately for progress.
+
+## Flags
+
+| Flag | Behavior |
+|---|---|
+| *(none)* | Auto. TTY: `\r`-rewriting single line. Non-TTY: plain line-per-event on stderr. |
+| `--progress-json` | Force JSON-lines mode on stderr (this doc). |
+| `--quiet` | Suppress progress entirely. Warnings and final output still print. |
+| `--progress-interval=<ms>` | Override the minimum interval between tick emits (default 1000). |
+
+Global flags: parsed by `src/core/cli-options.ts` before command dispatch,
+so `gbrain --progress-json doctor` works the same as
+`gbrain doctor --progress-json` (the latter also works — per-command
+parsers see the flag via the shared `CliOptions` singleton).
+
+## Event types
+
+Every event is a single-line JSON object with these common fields:
+
+| Field | Type | Notes |
+|---|---|---|
+| `event` | string | One of: `start`, `tick`, `heartbeat`, `finish`, `abort`. |
+| `phase` | string | Machine-stable snake_case, dot-separated. See "Phase names" below. |
+| `ts` | ISO 8601 UTC string | Event emission time. |
+| `elapsed_ms` | number | Ms since the phase started. Present on `tick`/`heartbeat`/`finish`/`abort`. |
+
+### `start`
+
+Emitted when a phase begins.
+
+```json
+{"event":"start","phase":"doctor.db_checks","ts":"2026-04-20T12:34:56.789Z"}
+{"event":"start","phase":"import.files","total":52000,"ts":"2026-04-20T12:34:56.789Z"}
+```
+
+Optional fields:
+
+- `total` — the total item count if known at start.
+
+### `tick`
+
+Emitted periodically during iteration. Time- and item-gated: the reporter
+won't emit more often than `minIntervalMs` (default 1000) and
+`minItems` (default `max(10, ceil(total/100))`).
+
+```json
+{"event":"tick","phase":"orphans.scan","done":15000,"total":52000,"pct":28.8,"elapsed_ms":4200,"eta_ms":10300,"ts":"..."}
+```
+
+Fields:
+
+- `done` — items completed in this phase.
+- `total` — total items, if known. Omitted when the scan doesn't have a
+  total up front (e.g. a streaming iterator).
+- `pct` — `done/total * 100`, one decimal. Omitted when `total` is unknown.
+- `eta_ms` — projected ms until `done === total`, from the observed rate.
+  Omitted when `total` is unknown.
+- `note` — optional string with the current item (e.g. a slug or filename).
+
+### `heartbeat`
+
+Emitted for long-running single operations that don't iterate
+(e.g. `SELECT` against a 50K-row table). No `done`, no `total` — just a
+signal that work is still happening.
+
+```json
+{"event":"heartbeat","phase":"doctor.markdown_body_completeness","note":"scanning pages for truncation…","elapsed_ms":1000,"ts":"..."}
+```
+
+### `finish`
+
+Emitted when a phase completes normally.
+
+```json
+{"event":"finish","phase":"import.files","done":52000,"total":52000,"elapsed_ms":187000,"ts":"..."}
+```
+
+### `abort`
+
+Emitted by a single process-level SIGINT/SIGTERM handler that tracks every
+live phase. After `abort`, no further events emit for that phase.
+
+```json
+{"event":"abort","phase":"doctor.markdown_body_completeness","reason":"SIGINT","elapsed_ms":5300,"ts":"..."}
+```
+
+## Phase names
+
+Phases use `snake_case.dot.path` naming. A fresh reporter starts at the
+root; `child()` composition appends to the parent's current phase, so a
+sync that calls import emits `sync.import.<file>`, not `import.<file>`.
+
+Stable phase names shipped in v0.15.2:
+
+- `doctor.db_checks` (umbrella for all DB-side doctor checks)
+- `orphans.scan`
+- `embed.pages`
+- `extract.links_fs`, `extract.timeline_fs`, `extract.links_db`, `extract.timeline_db`
+- `import.files`
+- `sync.deletes`, `sync.renames`, `sync.imports`
+- `migrate.copy_pages`, `migrate.copy_links`
+- `repair_jsonb.run`, `repair_jsonb.<table>.<column>`
+- `backlinks.scan`
+- `lint.pages`
+- `integrity.auto`
+- `eval.single`, `eval.ab`
+- `export.pages`
+- `files.sync`
+
+Sub-phases exposed via `child()`:
+
+- `sync.import.files` — nested inside a sync
+- `apply_migrations.v0_12_2.jsonb_repair` — nested inside the orchestrator
+
+## Subprocess inheritance
+
+When a parent CLI spawns `gbrain …` child processes (mostly in
+`src/commands/migrations/*`), global flags (`--quiet`, `--progress-json`,
+`--progress-interval`) are propagated to the child's argv via the
+`childGlobalFlags()` helper in `src/core/cli-options.ts`. Child stderr
+passes straight through `stdio: 'inherit'` so the event stream is one
+merged JSONL feed on the parent's stderr.
+
+One exception: the orchestrator phase in `migrations/v0_12_2.ts` that
+captures child stdout (`repair-jsonb --dry-run --json` for verification)
+does not pass `--progress-json` to avoid any risk of stdout pollution
+breaking the orchestrator's `JSON.parse`. Its stdio is explicit:
+`['ignore', 'pipe', 'inherit']` so stderr still flows through.
+
+## Minion jobs
+
+`gbrain jobs work` (the Minion worker daemon) keeps progress in the DB,
+not on stderr. Each Minion handler that runs a bulk core (embed, sync,
+extract, import, backlinks) calls `job.updateProgress({done, total,
+…})` per iteration. Agents read per-job progress via the
+`get_job_progress` MCP operation or `gbrain jobs get <id>`.
+
+The `jobs work` daemon itself emits coarse one-line-per-job stderr output
+for liveness only. Per-page detail lives in the DB.
+
+## Compatibility
+
+- **Added**: only. A new event type, a new field, a new phase name — all
+  safe. Agents must ignore unknown fields and unknown event types.
+- **Removed/renamed**: never without a major version bump.
+- **Schema changes**: announced in `CHANGELOG.md` and in
+  `skills/migrations/v<next>.md`.
+
+If your agent depends on this schema and something surprises you, open
+an issue with the event you received and what you expected.

+## Cross-source citation format (v0.18.0+)
+
+When a brain has multiple sources (wiki, gstack, yc-media, etc.), every
+citation MUST include the source id: `[source-id:slug]`. Example:
+
+> You told me about the retry budget approach — see
+> [wiki:topics/resilience] and [gstack:plans/retry-policy] for where

+
+Rules:
+- The key is `sources.id` (immutable), never `sources.name` (mutable display).
+- Single-source brains still write `[default:slug]` OR may omit the prefix
+  for backward compat.
+- Every page payload returned by `search`, `query`, `get_page`, `list_pages`
+  carries `source_id` — always use it when citing, never guess.
+
+If a search result has `source_id: "gstack"` and `slug: "plans/foo"`,

+# v0.14.0 Migration: Adopt the `shell` job type
+
+**Audience: host agents (OpenClaw deployments, Hermes operators, future
+hosts) reading this AFTER `gbrain apply-migrations` has run. There is no
+mechanical orchestrator for this release — every change described here
+is host-specific and requires operator judgment per cron.** Shell jobs
+are off by default on upgrade (nothing breaks). This file walks the
+host agent through enabling and adopting them.
+
+## Iron rules
+
+1. **Never auto-rewrite the operator's crontab.** Crontab entries are
+   host-specific code per the CLAUDE.md "host-specific code" exception.
+   Every rewrite is an explicit human approval, per cron, with a diff.
+2. **LLM-requiring crons stay on the gateway.** If the cron's work
+   includes reasoning (sentiment classification, triage, synthesis,
+   prose generation), it belongs on the gateway. Moving it to a shell
+   job throws away the LLM session the cron needs.
+3. **Deterministic crons are the only candidates.** API fetch, token
+   refresh, database read + markdown write, HTTP refresh call, scrape.
+   If the script is `node scripts/x.mjs` or `curl ... | jq` or similar
+   and does zero LLM work, it's a candidate.
+
+## Step 1: Enable the worker
+
+Pick the engine the operator is on:
+
+**Postgres** (most OpenClaw/Hermes deployments):
+
+```bash
+# In the worker bootstrap, export the env flag and run the daemon:
+GBRAIN_ALLOW_SHELL_JOBS=1 gbrain jobs work
+```
+
+The worker claims shell jobs from the queue and executes them. Retries,
+backoff, and dead-letter all work the same as sync/embed jobs.
+
+**PGLite**: no persistent worker, per-tick inline execution only:
+
+```bash
+# Every crontab invocation must use --follow; PGLite's worker daemon
+# exits immediately due to exclusive file lock.
+GBRAIN_ALLOW_SHELL_JOBS=1 gbrain jobs submit shell \
+  --params '{"cmd":"...","cwd":"..."}' --follow
+```
+
+## Step 2: Audit the operator's cron manifest
+
+Read the operator's cron manifest. Typical locations:
+
+- `~/.claude/cron/jobs.json` (OpenClaw)
+- `scripts/service-manager.sh` in the host repo
+- System crontab (`crontab -l`)
+
+For each entry, classify:
+
+| Pattern | Class | Action |
+|---------|-------|--------|
+| `agentTurn <skill>` or any OpenClaw-dispatched LLM skill | LLM-requiring | **Leave as-is.** Needs gateway. |
+| `node scripts/*.mjs` that hits an API and writes markdown | Deterministic | Propose shell-job rewrite. |
+| Token refresh (`ycli token-refresh`, `x-oauth2-refresh`) | Deterministic | Propose shell-job rewrite. |
+| Scrape + write (`frameio-scan`, `flight-tracker`) | Deterministic | Propose shell-job rewrite. |
+| Audio transcription or any LLM-dependent extract | LLM-requiring | Leave as-is. |
+| `bash` wrapper scripts that may call LLM tools internally | Ambiguous | Ask the operator. Don't assume. |
+
+## Step 3: Propose rewrites per cron
+
+For each deterministic cron, propose the exact rewrite with a diff. Show
+the operator both sides. Let them approve per-cron, not in bulk.
+
+**Before** (LLM gateway):
+```
+OpenClaw cron: x-garrytan-unified, 3 13,16,19,22,1,4,7,10 * * *
+  → runs agentTurn x-garrytan-unified
+  → boots Opus context, invokes script, returns
+```
+
+**After** (Minions worker):
+```cron
+3 13,16,19,22,1,4,7,10 * * * \
+  gbrain jobs submit shell \
+    --params '{"cmd":"node /data/.openclaw/workspace/scripts/x-garrytan-daily.mjs","cwd":"/data/.openclaw/workspace"}' \
+    --max-attempts 3 --timeout-ms 300000
+```
+
+Rewrite rules:
+- `cwd` is required and must be an absolute path. Operator picks it. It
+  should be the directory the script expects to run in (the host repo
+  root, typically).
+- `--max-attempts 3` matches the default Minions retry policy. Override
+  if the script is non-idempotent and should only run once per fire.
+- `--timeout-ms N` caps the child's wall-clock runtime. Set to the 95th
+  percentile of the script's observed runtime, plus slack. Examples:
+  token refresh → 30s; API fetch → 300s; scrape → 600s.
+- **PGLite operators:** add `--follow` to every line. Skip Step 1.
+
+## Step 4: Secrets that the script needs
+
+Shell jobs receive a minimal env allowlist by default: `PATH, HOME,
+USER, LANG, TZ, NODE_ENV`. They do NOT inherit `OPENAI_API_KEY`,
+`ANTHROPIC_API_KEY`, `DATABASE_URL`, or any other worker env vars.
+
+If a cron's script needs an API key, name it explicitly:
+
+```bash
+gbrain jobs submit shell \
+  --params '{"cmd":"node scripts/yc-sync.mjs","cwd":"/data/.openclaw/workspace","env":{"YC_API_TOKEN":"'"$YC_API_TOKEN"'"}}'
+```
+
+The shell expands `$YC_API_TOKEN` at submit time. The worker receives
+the JSON with the literal token value. Audit log does not log env
+values (keys don't carry sensitive data; values never appear).
+
+## Step 5: Verify the first migrated cron
+
+After rewriting ONE cron with the operator's approval:
+
+1. Wait for the next scheduled fire (or trigger manually: `gbrain jobs
+   submit shell --params '...' --follow`).
+2. Check `gbrain jobs list --status completed --name shell --limit 5`
+   for the result.
+3. `gbrain jobs get <id>` shows `exit_code`, `stdout_tail`, `stderr_tail`,
+   `duration_ms`.
+4. Compare against the pre-migration behavior: did it do the same work?
+   Same output files changed? Same side effects?
+
+Only after one cron is verified working end-to-end should the operator
+approve the next batch.
+
+## Step 6: Starvation sanity check
+
+If the operator submits shell jobs but forgot to set
+`GBRAIN_ALLOW_SHELL_JOBS=1` on the worker, jobs sit in `waiting`
+indefinitely. The CLI warns on submission, but for daemon-style
+deployments the warning scrolls past. Add this to the operator's
+ops-check runbook:
+
+```bash
+gbrain jobs list --status waiting --name shell
+```
+
+If rows pile up here, either (a) no worker has the env flag set, or
+(b) the worker crashed. Fix by restarting with the flag.
+
+## Non-goals (explicitly deferred to later releases)
+
+- **Automatic crontab rewrites.** Deferred to a future `gbrain
+  crontab-to-minions <file>` helper. P1 in TODOS.md.
+- **DB-backed scheduler.** `minion_schedules` table replaces host
+  crontab entirely. P1 in TODOS.md.
+- **Orphaned-shell-job stats.** `gbrain jobs stats --orphaned` would
+  surface the "no worker with env flag" case. P2 in TODOS.md.
+- **Configurable buffer sizes.** Output tails are fixed at 64KB stdout
+  / 16KB stderr. P2 in TODOS.md.
+
+## When to stop
+
+The migration is done when:
+
+1. The worker runs with `GBRAIN_ALLOW_SHELL_JOBS=1` (Postgres) or every
+   cron uses `--follow` (PGLite).
+2. Every deterministic cron the operator approved has been rewritten.
+3. The operator has verified at least one full cron fire cycle
+   end-to-end and confirmed the output matches pre-migration.
+4. `gbrain jobs stats` shows shell jobs completing at expected rates
+   with few or zero retries.
+
+Gateway CPU should visibly drop after the first few rewrites. That's
+the signal the adoption is working.

+# v0.15.2 Migration: Bulk-action progress streaming
+
+**Audience: host agents reading this after `gbrain apply-migrations`
+has run. v0.15.2 is purely additive to the CLI surface, there is no
+schema change, no data rewrite, and no orchestrator for this release.**
+Your binaries just got observable. This file tells you how to use it.
+
+## Mechanical migration: nothing
+
+There is no mechanical step. If `gbrain upgrade` completed, progress
+events are already flowing the next time you invoke a bulk command.
+Read on to know what's there and how to consume it.
+
+## What's new at the CLI
+
+### Three new global flags
+
+These work on any `gbrain` subcommand:
+
+- `--progress-json` — emit one JSON event per line on stderr.
+- `--quiet` — suppress progress output entirely.
+- `--progress-interval=<ms>` — minimum ms between progress emits
+  (default 1000).
+
+Parsed before command dispatch, so both work:
+
+```
+gbrain --progress-json doctor --json
+gbrain doctor --json --progress-json
+```
+
+### Per-TTY behavior
+
+Without `--progress-json`:
+
+- **TTY:** `\r`-rewriting single-line progress on stderr (fancy).
+- **Non-TTY (pipe, CI, agent):** one plain-text line per event on
+  stderr. No JSON, no noise. Human-readable.
+
+The default was deliberately NOT JSON-on-non-TTY. Shell pipelines
+that just pipe `gbrain ... | less` should get readable logs, not a
+JSON blob. Agents opt in to JSON explicitly.
+
+## What's new per command
+
+Fourteen commands now stream progress through the shared reporter:
+
+| Command | What you'll see |
+|---------|-----------------|
+| `doctor` | `doctor.db_checks` phase + per-check heartbeats, including a 1s heartbeat while `markdown_body_completeness` scans |
+| `orphans` | `orphans.scan` heartbeat while the anti-join runs |
+| `embed` | `embed.pages` with per-page ticks |
+| `files sync` | `files.sync` with per-file ticks |
+| `export` | `export.pages` with per-page ticks |
+| `import` | `import.files` with per-file ticks (replaces per-100 stdout logs) |
+| `extract [links|timeline|all]` (fs + db) | `extract.links_fs` / `extract.timeline_db` etc. |
+| `sync` | `sync.deletes`, `sync.renames`, `sync.imports` phases |
+| `migrate --to ...` | `migrate.copy_pages`, `migrate.copy_links` |
+| `repair-jsonb` | `repair_jsonb.run` + per-column heartbeats |
+| `check-backlinks` | `backlinks.scan` heartbeat |
+| `lint` | `lint.pages` per-page ticks |
+| `integrity auto` | `integrity.auto` per-page ticks |
+| `eval` | `eval.single` / `eval.ab` per-query ticks |
+| `apply-migrations` (v0_11/v0_12_0/v0_12_2) | Child processes inherit the parent's progress mode |
+
+## JSON event schema
+
+Documented in `docs/progress-events.md` (canonical reference). Stable
+from v0.15.2, additive changes only.
+
+Quick agent cheat sheet:
+
+```json
+{"event":"start","phase":"doctor.db_checks","ts":"..."}
+{"event":"tick","phase":"orphans.scan","done":15000,"total":52000,"pct":28.8,"elapsed_ms":4200,"eta_ms":10300,"ts":"..."}
+{"event":"heartbeat","phase":"doctor.markdown_body_completeness","note":"scanning pages for truncation...","elapsed_ms":1000,"ts":"..."}
+{"event":"finish","phase":"doctor.db_checks","elapsed_ms":187000,"ts":"..."}
+{"event":"abort","phase":"orphans.scan","reason":"SIGINT","elapsed_ms":5300,"ts":"..."}
+```
+
+Parser rules:
+
+1. One JSON object per line on stderr.
+2. Ignore unknown event types and unknown fields. Schema is additive.
+3. Group by `phase` prefix to track one run: all `doctor.*` events
+   belong to the same `doctor` invocation.
+4. `total` / `pct` / `eta_ms` are absent when the scan doesn't have a
+   total up front (e.g. heartbeat-only paths). Don't assume they exist.
+
+## Minion jobs
+
+`gbrain jobs work` (the Minion worker daemon) writes progress to the
+DB via `job.updateProgress`, not to stderr. Read per-job progress via
+the `get_job_progress` MCP op or:
+
+```bash
+gbrain jobs submit embed
+# while it runs:
+gbrain jobs get <id>   # .progress updates live as the handler ticks
+```
+
+The `embed` Minion handler is wired as of v0.15.2. Other bulk cores
+(`sync`, `extract`, `backlinks`, `import`, `autopilot-cycle`) have the
+callback plumbing ready and will follow.
+
+## Backward-compatibility warnings
+
+Five commands moved per-page progress from stdout to stderr:
+
+- `embed` (was `\r`-on-stdout)
+- `files sync` (was `\r`-on-stdout)
+- `export` (was `\r`-on-stdout, newly in scope)
+- `migrate-engine` (was per-50 `console.log` to stdout)
+- `import` (was per-100 `console.log` to stdout)
+
+If you have scripts that grep `stdout` for progress strings like
+`Progress: 1234/52000` or `\r  1234/52000 pages...` — those strings
+now live on stderr. The final data summaries (`Embedded N chunks
+across M pages`, `Import complete`, etc.) remain on stdout so the
+"did it finish" signal is unchanged.
+
+`integrity auto` still writes `~/.gbrain/integrity-progress.jsonl`,
+but its role is now "resume marker only" — live progress goes through
+the reporter. If you depended on tailing that file for real-time
+progress, switch to the stderr stream.
+
+## Verification
+
+```bash
+# Your agent sees structured events; stdout stays JSON-parseable:
+gbrain --progress-json doctor --json > doctor.json 2> doctor.progress.log
+wc -l doctor.progress.log   # should be non-zero
+jq . doctor.json             # should parse cleanly
+
+# For a very large brain, watch the heartbeat:
+gbrain --progress-json doctor 2>&1 >/dev/null | grep '"event"'
+```
+
+If you see silence for more than a second or two on a non-trivial
+command, file an issue with the exact command and the first 100 lines
+of stderr.
+
+## That's the whole migration
+
+No mechanical step. No config change. Agents that parse `stdout` keep
+working; agents that want progress now have it on a clean stderr
+channel with a documented schema.

+# v0.17.0 Migration: `gbrain dream` + unified maintenance cycle
+
+**Audience: agents + humans upgrading from v0.16.x. There is no
+mechanical migration step required — the schema migration (v16
+cycle-lock table) and behavior changes all apply automatically on
+upgrade. This file documents what changed, how to verify it, and
+the one opt-out users may care about.**
+
+## What changed
+
+### New command: `gbrain dream`
+
+The brand-promise one-liner. Runs one brain maintenance cycle and
+exits. Designed for cron.
+
+```
+gbrain dream                     # full 6-phase cycle
+gbrain dream --dry-run --json    # preview, agent-readable
+gbrain dream --phase lint        # single-phase (fast, targeted)
+gbrain dream --pull              # git pull before syncing
+0 2 * * * gbrain dream --json    # nightly cron
+```
+
+See `gbrain dream --help` for the full flag reference.
+
+### Autopilot now runs lint + orphan sweep
+
+`gbrain autopilot --install` users: on upgrade, your daemon's cycle
+gains two phases it didn't run before:
+
+- **lint --fix** — auto-fixes LLM artifacts, placeholder dates, bad
+  citations across the brain. Modifies files on disk.
+- **orphan sweep** — reports (read-only) pages with no inbound
+  wikilinks. Visible in `gbrain jobs list` output for each
+  `autopilot-cycle` job.
+
+No action required. The new phases run on the daemon's existing
+interval.
+
+### Shared primitive: `src/core/cycle.ts`
+
+Three callers (dream CLI, autopilot inline path, autopilot-cycle
+Minions handler) now all delegate to `runCycle(engine, opts)`. One
+source of truth for what happens overnight.
+
+### Cycle coordination via a DB lock table
+
+`gbrain_cycle_locks` (new table, migration v16) replaces
+session-scoped `pg_try_advisory_lock` which the v0.15.4
+PgBouncer-transaction-pooler fix silently broke. The table has a
+TTL (30 min), refreshed between phases, so crashed holders
+auto-release.
+
+## Verify after upgrade
+
+```bash
+# 1. Dream command exists:
+gbrain dream --help
+
+# 2. Run a dry cycle (safe, no writes):
+gbrain dream --dry-run --json
+
+# 3. If you run autopilot --install:
+gbrain jobs list --status complete | head -5
+# Each `autopilot-cycle` entry now has 6 phases in its report,
+# not 4. Check a recent one with `gbrain jobs get <id>`.
+
+# 4. Schema migration landed:
+gbrain doctor  # should show no pending migrations
+```
+
+Expected `gbrain dream --dry-run` output on a healthy brain:
+
+```
+Brain is healthy. 6 phase(s) checked in 1.3s.
+```
+
+Or with `--json`:
+
+```json
+{
+  "schema_version": "1",
+  "status": "clean",
+  "phases": [...],
+  "totals": { "lint_fixes": 0, "backlinks_added": 0, ... }
+}
+```
+
+## Opt-outs for autopilot-installed users
+
+If you explicitly do NOT want autopilot's daemon modifying files
+(lint + backlinks phases write to disk):
+
+**Option 1: disable those phases in cron-dream but keep autopilot
+running.** Since dream is separate, you can run just the phases
+you want from cron without touching autopilot:
+
+```bash
+# e.g. only re-embed and orphan-sweep nightly, skip file mutations:
+0 2 * * * gbrain dream --phase orphans
+```
+
+**Option 2: uninstall autopilot and use cron-dream only.**
+
+```bash
+gbrain autopilot --uninstall
+# Then add to your crontab:
+0 2 * * * gbrain dream --pull
+```
+
+**Option 3: accept the default.** The new phases are conservative:
+lint only fixes known-safe artifacts (em dashes, placeholder dates),
+never destructive. Back-link fills are additive. If something does
+go wrong, `gbrain dream --dry-run` always tells you what WOULD
+change before you run it for real.
+
+## Troubleshooting
+
+**"cycle_already_running" in dream output:**
+Another cycle (probably autopilot's daemon) is holding the lock.
+Expected behavior — dream skipped to avoid racing the daemon. The
+daemon's next interval will pick up the work.
+
+**`gbrain dream --dry-run` reports changes when you expected none:**
+Check `gbrain doctor` for drift: lint issues, stale embeddings,
+missing back-links. Dream's dry-run is the honest preview of what
+autopilot's daemon will do on its next cycle.
+
+**Minion `autopilot-cycle` jobs failing after upgrade:**
+Open a GitHub issue with the output of `gbrain jobs get <id>` for a
+failing job. The new runCycle-backed handler preserves the
+partial-failure semantic (one phase failing doesn't block future
+cycles), but specific phases may surface new error classes.
+
+## What did NOT change
+
+- `gbrain autopilot --install` machinery (launchd / systemd /
+  crontab generators). Existing installs keep working.
+- `~/.gbrain/autopilot.lock` daemon-singleton lockfile. Separate
+  concern from the new per-cycle lock.
+- `gbrain jobs` interface. `gbrain jobs get <id>` now shows a
+  richer report structure (schema_version:"1"), but the surface
+  API is stable.

+# v0.17.0 Migration: Multi-source brains
+
+**Audience: host agents reading this after `gbrain apply-migrations`
+has run. v0.17.0 installs a schema primitive for multi-source and
+exposes a `sources` CLI subcommand. Existing single-source brains
+keep working unchanged — they live under a seeded `default` source
+that preserves all prior behavior.**
+
+## Mechanical migration: automatic, no action required
+
+`gbrain upgrade` chains to `gbrain apply-migrations --yes`, which
+runs:
+
+- **migration v16** — creates the `sources` table, seeds `default`
+  with `{"federated": true}` config, inherits your pre-v0.17
+  `sync.repo_path` and `sync.last_commit` into the default row.
+- **migration v17** — adds `pages.source_id TEXT NOT NULL DEFAULT
+  'default' REFERENCES sources(id)`. Swaps the global `UNIQUE(slug)`
+  constraint for composite `UNIQUE(source_id, slug)`. Engine
+  upserts simultaneously re-target `ON CONFLICT (source_id, slug)`
+  so the constraint swap and the write path land atomically.
+
+Both migrations are idempotent. Safe to re-run.
+
+Later point releases (v0.17.1 and v0.18.0) will layer:
+- v0.17.1: ACL enforcement via a caller-identity primitive (the
+  JSONB slot for `access_policy` ships now; enforcement waits for
+  identity to be designed).
+- v0.18.0: Session ingest (`.jsonl` transcripts, raised size cap,
+  session PageType) AND per-source retention/TTL at the same time.
+
+## What's new for agents
+
+### `sources` CLI subcommand
+
+```
+gbrain sources add <id> --path <p> [--name <n>] [--federated|--no-federated]
+gbrain sources list [--json]
+gbrain sources remove <id> [--yes] [--dry-run] [--keep-storage]
+gbrain sources rename <id> <new-display-name>
+gbrain sources default <id>
+gbrain sources attach <id>    # write .gbrain-source in CWD
+gbrain sources detach         # remove .gbrain-source
+gbrain sources federate <id>
+gbrain sources unfederate <id>
+```
+
+Source id rules: `[a-z0-9](?:[a-z0-9-]{0,30}[a-z0-9])?` — start + end
+with alnum, optional interior hyphens, max 32 chars. Immutable after
+creation (rename only changes the display name). Used as the stable
+citation key in `[source:slug]` references.
+
+### Per-directory default
+
+Running `gbrain sources attach gstack` inside `~/.gstack/` writes a
+`.gbrain-source` file containing the single word `gstack`. Any
+gbrain command run from that directory (or any subdirectory) auto-
+selects `gstack` as the default source. `gbrain sources detach`
+removes the dotfile.
+
+Resolution priority for the source a command targets:
+
+1. Explicit `--source <id>` flag.
+2. `GBRAIN_SOURCE` env var.
+3. `.gbrain-source` dotfile in CWD or any ancestor.
+4. Registered source whose `local_path` contains CWD (longest
+   prefix wins — nested `~/gstack` + `~/gstack/plans` resolves to
+   `plans` when deeper).
+5. Brain-level default set via `gbrain sources default <id>`.
+6. Literal `default` (backward-compat fallback).
+
+### Federation semantics
+
+- `federated=true` (only the `default` source has this out of the
+  box, by migration): appears in unqualified `gbrain search "X"`
+  results.
+- `federated=false` (new sources default to this): only appears
+  when `--source <id>` is passed.
+
+Interactive `gbrain sources add` prompts for federation; non-
+interactive uses `--federated` / `--no-federated`. Flip later with
+`gbrain sources federate <id>` / `unfederate <id>`.
+
+### Citation contract (for agents)
+
+When agents get multi-source search results they MUST cite pages
+in `[source-id:slug]` form. Example:
+
+> You told me about the distillation protocol — see
+> [wiki:topics/ai] and [gstack:plans/multi-repo] for where this
+> came from.
+
+Citations are keyed on `sources.id` (immutable), never
+`sources.name` (mutable display). If a user renames a source via
+`gbrain sources rename`, existing citations stay valid.
+
+## What's NOT in v0.17.0 yet
+
+The following land in later Steps of this release cycle (already
+on the branch but gated until the matching code ships):
+
+- `ingest_log.source_id` — lands with Step 5 sync rewrite.
+- `links.resolution_type` + qualified `[[source:slug]]` wikilink
+  parsing — lands with Step 4 link-extraction rewrite.
+- `files.page_slug → page_id` FK rewrite + `file_migration_ledger`
+  + storage object prefixing — lands with Step 7 storage backfill.
+- Source-aware search dedup — lands with Step 3.
+- `gbrain sources import-from-github <url>` — deferred to a patch
+  release after the plumbing stabilizes.
+
+Existing callers continue to work against the `default` source. No
+agent behavioral change is required; the new capabilities are
+opt-in via the new `sources` CLI surface.
+
+## Host-repo actions
+
+None required. If your host agent manages the brain via the
+standard `gbrain sync` flow, it continues to target the default
+source and sees no behavioral change. To start using multi-source:
+
+```
+# Register a new source
+gbrain sources add gstack --path ~/.gstack --no-federated
+
+# Pin that directory to it so no --source flag is needed
+cd ~/.gstack
+gbrain sources attach gstack
+
+# Ingest
+gbrain sync --source gstack
+```
+
+Or see `docs/guides/multi-source-brains.md` for the full three
+canonical scenarios (unified, purpose-separated, mixed).

+
+SUBMITTING
+  gbrain agent run <prompt>
+    --subagent-def <name>        Named plugin subagent (from GBRAIN_PLUGIN_PATH)
+    --model <id>                 Anthropic model id (defaults to sonnet)
+    --max-turns <n>              Max assistant turns (default 20)
+    --tools a,b,c                Subset of registered tool names (comma list)
+    --timeout-ms <n>             Per-job wall-clock timeout
+    --fanout-manifest <path>     JSON array of {prompt, input_vars?} — one child each
+    --follow                     Tail status until terminal (default on TTY)
+    --detach                     Submit + print job id, exit immediately
+
+  Flags after \`run\` up to the first unrecognized token are parsed; the
+  remainder is the prompt. Use \`--\` to explicitly terminate flag parsing.

+    --since <spec>               ISO-8601 timestamp OR relative ("5m","1h","2d")
+
+NOTES
+  Submitting subagent jobs is trusted-only; MCP submitters receive
+  permission_denied. The worker needs ANTHROPIC_API_KEY set, or the
+  first LLM turn of a claimed job fails.

+ *   gbrain integrity auto               Three-bucket repair with confidence
+ *   gbrain integrity --dry-run          Same as auto, no writes
+ *
+ * Three-bucket confidence (contract with x_handle_to_tweet resolver):
+ *   >= 0.8 → auto-repair through BrainWriter transaction
+ *   0.5–0.8 → append to ~/.gbrain/integrity-review.md for human review
+ *   < 0.5 → skip, log to ~/.gbrain/integrity.log.jsonl

+ * v0.13.0 migration — grandfather `validate: false` onto existing pages.
+ *
+ * The Knowledge Runtime BrainWriter ships pre-commit citation / link /
+ * back-link / triple-HR validators. A fresh brain passes them trivially.
+ * An existing brain with years of accumulated pages does NOT — legitimate
+ * pages without strict citation formatting exist all over the place.
+ *
+ * This migration walks every page and adds `validate: false` to frontmatter
+ * where the field isn't already present. Pages with that flag bypass the
+ * validators entirely, so strict-mode rollout doesn't break existing
+ * content. `gbrain integrity --auto` clears the flag per-page as it writes
+ * proper citations.
+ *
+ * Idempotency: pages that already have `validate: false` or `validate: true`
+ * are skipped. Running twice is a no-op on the second pass.
+ *
+ * Reversibility: every page touched is logged to
+ * ~/.gbrain/migrations/v0_13_1-rollback.jsonl with its pre-migration
+ * frontmatter snapshot. Roll back by re-applying those snapshots via
+ * `gbrain apply-migrations --rollback v0.13.0` (future CLI; not in scope).
+ *
+ * Scale: on a 30K-page brain, ~15s on Postgres, ~30s on PGLite. Batched in
+ * chunks of 100 with a commit per batch so interruption losses are bounded.
+ *
+ * Snapshot-slugs rule: reads engine.getAllSlugs() upfront into an in-memory
+ * Set before iterating. Prior learning [listpages-pagination-mutation]: any
+ * batch write that mutates updated_at during OFFSET pagination is unstable.
+ * getAllSlugs returns a full snapshot that isn't invalidated by our writes.
+ *
+ * Safety: does NOT call saveConfig. Prior learning [gbrain-init-default-pglite-flip]:
+ * bare `gbrain init` defaults to PGLite and overwrites Postgres config.
+ * This migration uses the standalone engine-factory flow with the existing
+ * config; it never writes config.

+ * v0.18.0 migration orchestrator — Multi-source brains.
+ *
+ * Split across sub-versions of the migration registry for safety:
+ *   - v16 (Step 1 / Lane A): additive-only. Installs sources table +
+ *     default row. Does NOT break any existing engine code.
+ *   - v17 (Step 2 / Lane B, future): breaking schema changes. Rides with
+ *     the engine API rewrite so ON CONFLICT (source_id, slug) lands
+ *     atomically with the composite UNIQUE.
+ *
+ * Phase structure (per /plan-ceo-review + /plan-eng-review):
+ *   A. Schema — gbrain init --migrate-only runs the migration chain up
+ *      to whichever v-prefix has shipped (v16 today, v17 next).
+ *   B. Storage backfill (Step 7, future) — ledger-driven object rewrite.
+ *   C. Verify — assert sources('default') exists today. Composite UNIQUE,
+ *      page_id backfill, and ledger completeness get added in Step 2.
+ *   D. (future) Delete old storage objects — only runs after C green.
+ *
+ * Idempotent: safe to re-run on partial state.
