GBrain is a personal knowledge brain and GStack mod for agent platforms. Pluggable engines: PGLite (embedded Postgres via WASM, zero-config default) or Postgres + pgvector

• hybrid search in a managed Supabase instance. gbrain init defaults to PGLite; suggests Supabase for 1000+ files. GStack teaches agents how to code. GBrain teaches agents everything else: brain ops, signal detection, content ingestion, enrichment, cron scheduling, reports, identity, and access control.

Architecture

Contract-first: src/core/operations.ts defines ~41 shared operations (adds find_orphans in v0.12.3). CLI and MCP server are both generated from this single source. Engine factory (src/core/engine-factory.ts) dynamically imports the configured engine ('pglite' or 'postgres'). Skills are fat markdown files (tool-agnostic, work with both CLI and plugin contexts).

Trust boundary: OperationContext.remote distinguishes trusted local CLI callers (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.

Key files

• src/core/operations.ts — Contract-first operation definitions (the foundation). Also exports upload validators: validateUploadPath, validatePageSlug, validateFilename. OperationContext.remote flags untrusted callers.
• src/core/engine.ts — Pluggable engine interface (BrainEngine). clampSearchLimit(limit, default, cap) takes an explicit cap so per-operation caps can be tighter than MAX_SEARCH_LIMIT. Exports LinkBatchInput / TimelineBatchInput for the v0.12.1 bulk-insert API (addLinksBatch / addTimelineEntriesBatch). As of v0.13.1, BrainEngine has a readonly kind: 'postgres' | 'pglite' discriminator so migrations (src/core/migrate.ts) and other consumers can branch on engine without instanceof + dynamic imports.
• src/core/engine-factory.ts — Engine factory with dynamic imports ('pglite' | 'postgres')
• src/core/pglite-engine.ts — PGLite (embedded Postgres 17.5 via WASM) implementation, all 40 BrainEngine methods. addLinksBatch / addTimelineEntriesBatch use multi-row unnest() with manual $N placeholders. 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. v0.22.0: searchKeyword and searchKeywordChunks multiply ts_rank by the source-factor CASE expression at the chunk-grain level; searchVector becomes a two-stage CTE — inner CTE keeps ORDER BY cc.embedding <=> vec so HNSW stays usable, outer SELECT re-ranks by raw_score * source_factor. Inner LIMIT scales with offset to preserve pagination contract. As of v0.22.6.1, initSchema() calls applyForwardReferenceBootstrap() BEFORE replaying SCHEMA_SQL — probes for the specific forward-referenced state the embedded schema blob needs (pages.source_id, links.link_source, links.origin_page_id, content_chunks.symbol_name, content_chunks.language, sources FK target table) and adds only what's missing. Closes the upgrade-wedge bug class that bit users 10+ times across 6 schema versions over 2 years (#239/#243/#266/#357/#366/#374/#375/#378/#395/#396). No-op on fresh installs and modern brains.
• src/core/pglite-schema.ts — PGLite-specific DDL (pgvector, pg_trgm, triggers)
• src/core/postgres-engine.ts — Postgres + pgvector implementation (Supabase / self-hosted). addLinksBatch / addTimelineEntriesBatch use INSERT ... SELECT FROM unnest($1::text[], ...) 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. v0.22.0: searchKeyword, searchKeywordChunks, and searchVector apply source-aware ranking by inlining the source-factor CASE and NOT (col LIKE …) hard-exclude clause from src/core/search/sql-ranking.ts. searchVector switches to a two-stage CTE (HNSW-safe inner ORDER BY, source-boost re-rank in the outer SELECT) and carries p.source_id through inner→outer for v0.18 multi-source callers. v0.22.1 (#406): _savedConfig retains the connect config; reconnect() tears down + recreates the pool from saved config (called by supervisor watchdog after 3 consecutive health-check failures). executeRaw is a single-statement passthrough — no per-call retry (D3 dropped that as unsound for non-idempotent statements; recovery is supervisor-driven). v0.22.1 (#363, contributed by @orendi84): connect() applies resolveSessionTimeouts() from db.ts as connection-time startup parameters (statement_timeout, idle_in_transaction_session_timeout) so orphan pgbouncer backends can't hold locks for hours. v0.22.1 (#409, contributed by @atrevino47): countStaleChunks() + listStaleChunks() server-side-filter on embedding IS NULL for embed --stale, eliminating ~76 MB/call client-side pull on a fully-embedded brain; upsertChunks() resets both embedding AND embedded_at to NULL when chunk_text changes without a new embedding (consistency). As of v0.22.6.1, initSchema() calls applyForwardReferenceBootstrap() BEFORE replaying SCHEMA_SQL on the same forward-reference probe set as the PGLite engine, so old Postgres brains pinned at v0.13/v0.18/v0.19 walk forward cleanly instead of wedging on column "..." does not exist.
• 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).
• src/core/db.ts — Connection management, schema initialization. v0.22.1 (#363, contributed by @orendi84): resolveSessionTimeouts() returns statement_timeout + idle_in_transaction_session_timeout (defaults: 5min each, env-overridable via GBRAIN_STATEMENT_TIMEOUT / GBRAIN_IDLE_TX_TIMEOUT / GBRAIN_CLIENT_CHECK_INTERVAL). Both connect() (module singleton) and PostgresEngine.connect() (worker pool) consume the result via postgres.js's connection option, sending GUCs as startup parameters that survive PgBouncer transaction mode (unlike the prior setSessionDefaults post-pool SET, kept as a back-compat no-op shim).
• src/commands/migrate-engine.ts — Bidirectional engine migration (gbrain migrate --to supabase/pglite)
• src/core/import-file.ts — importFromFile + importFromContent (chunk + embed + tags)
• src/core/sync.ts — Pure sync functions (manifest parsing, filtering, slug conversion)
• src/core/storage.ts — Pluggable storage interface (S3, Supabase Storage, local)
• src/core/storage-config.ts (v0.22.11) — Storage tiering: loadStorageConfig reads gbrain.yml, normalizes deprecated keys (git_tracked / supabase_only) to canonical (db_tracked / db_only) with once-per-process deprecation warning, and runs normalizeAndValidateStorageConfig (auto-fixes missing trailing /, throws StorageConfigError on tier overlap). Path-segment matcher: media/x/ does NOT match media/xerox/foo. Replaces gray-matter (broken on delimiter-less YAML) with a dedicated parser for the gbrain.yml shape.
• src/core/disk-walk.ts (v0.22.11) — walkBrainRepo(repoPath) returns Map<slug, {size, mtimeMs}> from one recursive readdirSync. Skips dot-dirs, node_modules, non-.md files. Used by gbrain storage status to replace per-page existsSync + statSync (~400K syscalls on 200K-page brains → tens).
• src/commands/storage.ts (v0.22.11) — gbrain storage status [--repo P] [--json]. Split into pure data (getStorageStatus) + JSON formatter + human formatter (ASCII-only per D10) matching the orphans.ts pattern. PageCountsByTier and DiskUsageByTier are distinct nominal types so swaps fail at compile time.
• gbrain.yml (brain repo root, v0.22.11) — Optional storage tiering config. Top-level storage: section with db_tracked: and db_only: array-valued keys. gbrain sync auto-manages .gitignore for db_only paths on successful sync (skips on dry-run, blocked-by-failures, submodule context, or GBRAIN_NO_GITIGNORE=1). gbrain export --restore-only [--repo P] [--type T] [--slug-prefix S] repopulates missing db_only files from the database.
• src/core/supabase-admin.ts — Supabase admin API (project discovery, pgvector check)
• src/core/file-resolver.ts — File resolution with fallback chain (local -> .redirect.yaml -> .redirect -> .supabase)
• src/core/chunkers/ — 3-tier chunking (recursive, semantic, LLM-guided). v0.19.0 adds code.ts — tree-sitter-based semantic chunker for 29 languages with embedded-asset WASMs (src/assets/wasm/), @dqbd/tiktoken cl100k_base tokenizer, small-sibling merging. CHUNKER_VERSION constant folded into importCodeFile's content_hash so chunker shape changes force clean re-chunks across releases.
• src/core/errors.ts (v0.19.0) — StructuredAgentError + buildError + serializeError. Every new v0.19.0 agent-facing surface (code-def, code-refs, usage errors) uses this envelope; matches v0.17.0 CycleReport.PhaseResult.error shape.
• src/assets/wasm/ (v0.19.0) — 36 tree-sitter grammar WASMs + tree-sitter runtime. Committed to the repo so bun --compile embeds them deterministically via import path from ... with { type: 'file' }. The CI guard scripts/check-wasm-embedded.sh fails the build if the compiled binary ever silently falls through to recursive chunks.
• src/commands/code-def.ts + src/commands/code-refs.ts (v0.19.0) — symbol definition + references lookup. Query content_chunks.symbol_name or chunk_text ILIKE with page_kind='code' filter. Auto-JSON when stdout is not a TTY (gh-CLI convention). Bypass the standard searchKeyword DISTINCT ON (slug) collapse so multiple call-sites from the same file surface.
• src/core/search/ — Hybrid search: vector + keyword + RRF + multi-query expansion + dedup. As of v0.22.0, searchKeyword / searchKeywordChunks / searchVector apply source-aware ranking at the SQL layer (curated content like originals/, concepts/, writing/ outranks bulk content like wintermute/chat/, daily/, media/x/). searchVector uses a two-stage CTE so source-boost re-ranking doesn't kill the HNSW index. Hard-exclude prefixes (test/, archive/, attachments/, .raw/ by default) filter at retrieval, not post-rank. Both gates honor detail !== 'high' so temporal queries surface chat pages normally.
• src/core/search/intent.ts — Query intent classifier (entity/temporal/event/general → auto-selects detail level)
• src/core/search/eval.ts — Retrieval eval harness: P@k, R@k, MRR, nDCG@k metrics + runEval() orchestrator
• src/core/search/source-boost.ts (v0.22.0) — Source-type boost map keyed by slug prefix. DEFAULT_SOURCE_BOOSTS (originals/ 1.5, concepts/ 1.3, writing/ 1.4, people/companies/deals/ 1.2, daily/ 0.8, media/x/ 0.7, wintermute/chat/ 0.5) and DEFAULT_HARD_EXCLUDES (test/, archive/, attachments/, .raw/). parseSourceBoostEnv / parseHardExcludesEnv parse comma-separated prefix:factor pairs from GBRAIN_SOURCE_BOOST / GBRAIN_SEARCH_EXCLUDE env vars. resolveBoostMap and resolveHardExcludes merge defaults + env + caller SearchOpts.exclude_slug_prefixes/include_slug_prefixes.
• src/core/search/sql-ranking.ts (v0.22.0) — Pure SQL string builders. buildSourceFactorCase(slugColumn, boostMap, detail) emits a CASE expression with longest-prefix-match wins (returns literal '1.0' when detail === 'high' for temporal-bypass parity with COMPILED_TRUTH_BOOST). buildHardExcludeClause(slugColumn, prefixes) emits NOT (col LIKE 'p1%' OR col LIKE 'p2%') — OR-chain wrapped in NOT, NOT NOT LIKE ALL/ANY (those quantifiers don't express set-exclusion). LIKE meta-character escape covers all three of %, _, AND \ (backslash matters because it's Postgres LIKE's default escape char). Single-quote doubling on SQL string literals so injection-style inputs are inert text.
• src/commands/eval.ts — gbrain eval command: single-run table + A/B config comparison
• src/core/embedding.ts — OpenAI text-embedding-3-large, batch, retry, backoff
• src/core/check-resolvable.ts — Resolver validation: reachability, MECE overlap, DRY checks, structured fix objects. v0.14.1: CROSS_CUTTING_PATTERNS.conventions is an array (notability gate accepts both conventions/quality.md and _brain-filing-rules.md). New extractDelegationTargets() parses > **Convention:**, > **Filing rule:**, and inline backtick references. DRY suppression is proximity-based via DRY_PROXIMITY_LINES = 40.
• src/core/repo-root.ts — Shared findRepoRoot(startDir?) (v0.16.4): walks up from startDir (default process.cwd()) looking for skills/RESOLVER.md. Zero-dependency module imported by both doctor.ts and check-resolvable.ts. Parameterized startDir makes tests hermetic.
• src/commands/check-resolvable.ts — Standalone CLI wrapper (v0.16.4) over checkResolvable(). Exports parseFlags, resolveSkillsDir, DEFERRED, runCheckResolvable. Exit rule: 1 on any issue (warnings OR errors), stricter than doctor's ok flag — honors README:259. Stable JSON envelope {ok, skillsDir, report, autoFix, deferred, error, message} — same shape on success and error paths. --fix path runs autoFixDryViolations BEFORE checkResolvable (same ordering as doctor). scripts/skillify-check.ts subprocess-calls gbrain check-resolvable --json (cached per process) and fails loud on binary-missing — no silent false-pass. v0.19: AGENTS.md workspaces now resolve natively (see src/core/resolver-filenames.ts) — gbrain inspects the 107-skill OpenClaw deployment whether the routing file is RESOLVER.md or AGENTS.md. DEFERRED[] is empty — Checks 5 + 6 shipped as real code, not issue URLs.
• src/core/resolver-filenames.ts (v0.19) — central list of accepted routing filenames (RESOLVER.md, AGENTS.md). Shared by findRepoRoot, check-resolvable, and skillpack install so every code path walks the same fallback chain.
• src/commands/skillify.ts + src/core/skillify/{generator,templates}.ts (v0.19) — gbrain skillify scaffold <name> creates all stubs for a new skill in one command: SKILL.md, script, tests, routing-eval.jsonl, resolver entry, filing-rules pointer. gbrain skillify check <script> runs the 10-step checklist (LLM evals, routing evals, check-resolvable gate, filing audit) against a candidate skill before it lands.
• src/commands/skillify-check.ts (v0.19) — gbrain skillpack-check agent-readable health report. Exit 0/1/2 for CI pipeline gating; JSON for debugging. Wraps check-resolvable --json, doctor --json, and migration ledger into one payload so agents can decide whether a human action is required.
• src/commands/skillpack.ts + src/core/skillpack/{bundle,installer}.ts (v0.19) — gbrain skillpack install drops gbrain's curated 25-skill bundle into a host workspace, managed-block style. Never clobbers local edits; tracks a skill manifest so subsequent install --update diffs cleanly. Bundle builder (skillpack/bundle.ts) packages the set from skills/ into a versioned payload.
• src/core/skill-manifest.ts (v0.19) — parser for skill-manifest.json records. Used by skillpack installer to detect drift between the shipped bundle and the user's local edits, so updates merge instead of overwriting.
• src/commands/routing-eval.ts + src/core/routing-eval.ts (v0.19) — gbrain routing-eval catches user phrasings that route to the wrong skill. Reads skills/<name>/routing-eval.jsonl fixtures ({intent, expected_skill, ambiguous_with?}). Structural layer runs in check-resolvable by default (zero API cost); --llm opts into a Haiku tie-break layer for CI. False positives surface before users hit them.
• src/core/filing-audit.ts + skills/_brain-filing-rules.json (v0.19) — Check 6 of check-resolvable. Parses new writes_pages: / writes_to: frontmatter on skills and audits their filing claims against the filing-rules JSON. Warning-only in v0.19, upgrades to error in v0.20.
• src/core/dry-fix.ts — gbrain doctor --fix engine. autoFixDryViolations(fixes, {dryRun}) rewrites inlined rules to > **Convention:** see [path](path). callouts via three shape-aware expanders (bullet / blockquote / paragraph). Five guards: working-tree-dirty (getWorkingTreeStatus() returns 3-state 'clean' | 'dirty' | 'not_a_repo'), no-git-backup, inside-code-fence, already-delegated (40-line proximity, consistent with detector), ambiguous-multi-match, block-is-callout. execFileSync array args (no shell — no injection surface). EOF newline preserved.
• src/core/backoff.ts — Adaptive load-aware throttling: CPU/memory checks, exponential backoff, active hours multiplier
• src/core/fail-improve.ts — Deterministic-first, LLM-fallback loop with JSONL failure logging and auto-test generation
• src/core/transcription.ts — Audio transcription: Groq Whisper (default), OpenAI fallback, ffmpeg segmentation for >25MB
• src/core/enrichment-service.ts — Global enrichment service: entity slug generation, tier auto-escalation, batch throttling
• src/core/data-research.ts — Recipe validation, field extraction (MRR/ARR regex), dedup, tracker parsing, HTML stripping
• src/commands/embed.ts — gbrain embed [--stale|--all] [--slugs ...]. v0.22.1 (#409, contributed by @atrevino47): --stale path now starts with engine.countStaleChunks() (single SELECT count(*) WHERE embedding IS NULL, ~50 bytes wire). On a fully-embedded brain that's a 1-line short-circuit — no further reads. When stale chunks exist, engine.listStaleChunks() returns just the chunks needing embeddings (slug + chunk_index + chunk_text + metadata, no vector(1536) payload). Caller groups by slug, embeds via OpenAI, re-upserts via upsertChunks. Replaces the prior page-walk that pulled every chunk's embedding column over the wire and discarded most.
• src/commands/extract.ts — gbrain extract links|timeline|all [--source fs|db]: batch link/timeline extraction. fs walks markdown files, db walks pages from the engine (mutation-immune snapshot iteration; use this for live brains with no local checkout). 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). v0.22.1 (#417): ExtractOpts.slugs?: string[] enables incremental extract — when set, extractForSlugs() reads ONLY those slugs' files (single combined links+timeline pass) instead of the full directory walk. CLI gbrain extract keeps full-walk behavior; the cycle path threads sync's pagesAffected through. walkMarkdownFiles(brainDir) still runs at line 455 to build allSlugs for link resolution — see TODOS.md for replacing it with engine.getAllSlugs().
• src/commands/graph-query.ts — gbrain graph-query <slug> [--type T] [--depth N] [--direction in|out|both]: typed-edge relationship traversal (renders indented tree)
• src/core/link-extraction.ts — shared library for the v0.12.0 graph layer. extractEntityRefs (canonical, replaces backlinks.ts duplicate) matches both [Name](people/slug) markdown links and Obsidian [[people/slug|Name]] wikilinks as of v0.12.3. extractPageLinks, inferLinkType heuristics (attended/works_at/invested_in/founded/advises/source/mentions), parseTimelineEntries, isAutoLinkEnabled config helper. DIR_PATTERN covers people, companies, deals, topics, concepts, projects, entities, tech, finance, personal, openclaw. Used by extract.ts, operations.ts auto-link post-hook, and backlinks.ts.
• src/core/minions/ — Minions job queue: BullMQ-inspired, Postgres-native (queue, worker, backoff, types, protected-names, quiet-hours, stagger, handlers/shell).
• src/core/minions/queue.ts — MinionQueue class (submit, claim, complete, fail, stall detection, parent-child, depth/child-cap, per-job timeouts, cascade-kill, attachments, idempotency keys, child_done inbox, removeOnComplete/Fail). add() takes a 4th trusted arg (separate from opts to prevent spread leakage); protected names in PROTECTED_JOB_NAMES require {allowProtectedSubmit: true} and the check runs trim-normalized (whitespace-bypass safe). v0.14.1 #219: add() plumbs max_stalled through with a [1, 100] clamp; omitted values let the schema DEFAULT (5) kick in. v0.19.0: handleWallClockTimeouts(lockDurationMs) is Layer 3 kill shot for jobs where FOR UPDATE SKIP LOCKED stall detection and the timeout sweep both fail to evict (wedged worker holding a row lock via a pending transaction). v0.19.1: maxWaiting coalesce path now uses pg_advisory_xact_lock keyed on (name, queue) to serialize concurrent submits for the same key, and filters on queue in addition to name so cross-queue same-name jobs don't suppress each other.
• 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. v0.22.1 (#403): per-job timeout fires abort.abort(new Error('timeout')) then a 30-second grace-then-evict safety net force-evicts the job from inFlight and marks it dead in DB if the handler ignores the abort signal — frees the slot even when a handler wedges (the 98-waiting-0-active prod incident driver).
• src/core/minions/supervisor.ts — MinionSupervisor process manager. Spawns gbrain jobs work as a child, restarts on crash with exponential backoff, periodic health check. v0.22.1 (#406): consecutiveHealthFailures counter; on 3 consecutive failures emits health_warn with reason: 'db_connection_degraded' and calls engine.reconnect() to swap in a fresh pool, then resets the counter. Worker exit classifier emits likely_cause field on worker_exited events: oom_or_external_kill (SIGKILL), graceful_shutdown (SIGTERM), runtime_error (code 1), clean_exit (code 0), unknown.
• 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/backpressure-audit.ts (v0.19.1) — sibling of shell-audit.ts for maxWaiting coalesce events. JSONL at ~/.gbrain/audit/backpressure-YYYY-Www.jsonl. Fires one line per coalesce with (queue, name, waiting_count, max_waiting, returned_job_id, ts). Closes the silent-drop vector the v0.19.0 maxWaiting guard introduced.
• 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/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). v0.22.10 (#521): the autopilot-cycle handler now forwards job.data.phases to runCycle (was previously discarded — caller-supplied phase selection silently became a full cycle). Phases are validated against ALL_PHASES from src/core/cycle.ts; invalid names are filtered out and an empty/missing array falls back to the default 6-phase cycle.
• src/commands/features.ts — gbrain features --json --auto-fix: usage scan + feature adoption salesman
• src/commands/autopilot.ts — gbrain autopilot --install: self-maintaining brain daemon (sync+extract+embed)
• src/mcp/server.ts — MCP stdio server (generated from operations). v0.22.7: tool-call handler delegates to dispatchToolCall from src/mcp/dispatch.ts so stdio + HTTP transports share one validation, context-build, and error-format path.
• src/mcp/dispatch.ts (v0.22.7) — Shared tool-call dispatch consumed by both stdio (server.ts) and HTTP (http-transport.ts). Exports dispatchToolCall(engine, name, params, opts), buildOperationContext(engine, params, opts), and validateParams(op, params). Single source of truth for (ctx, params) handler arg order and the 5-field OperationContext shape (engine + config + logger + dryRun + remote). Defaults to remote: true (untrusted); local CLI callers pass remote: false. Closed F1 (reversed handler args) + F2 (incomplete OperationContext) + F3 (no param validation) drift bugs in the original v0.22.5 HTTP transport.
• src/mcp/rate-limit.ts (v0.22.7) — Bounded-LRU token-bucket limiter for gbrain serve --http. buildDefaultLimiters() returns the two-bucket pipeline used by http-transport: pre-auth IP (default 30/60s, fires BEFORE the DB lookup so brute-force load against access_tokens is actually capped) + post-auth token-id (default 60/60s). Tracks lastTouchedMs separately from lastRefillMs so an exhausted key can't be reset by hammering past the TTL. LRU cap (default 10K keys) bounds memory under attacker-controlled key growth; TTL prune at 2× window evicts abandoned buckets.
• src/mcp/http-transport.ts (v0.22.7, rewrite) — gbrain serve --http HTTP transport. Postgres-only — fails fast at startup on PGLite (the access_tokens table only exists on Postgres). Bearer auth against SHA-256 hashes in access_tokens. CORS default-deny via GBRAIN_HTTP_CORS_ORIGIN allowlist. Body cap stream-counted (1 MiB default via GBRAIN_HTTP_MAX_BODY_BYTES) so chunked transfers without Content-Length still hit the cap. last_used_at SQL-level debounce (one UPDATE per token per 60s). Per-request audit row in mcp_request_log with token_name + operation + status + latency. Optional GBRAIN_HTTP_TRUST_PROXY=1 honors X-Forwarded-For — only safe when bound to a private interface AND the proxy strips client-supplied XFF (otherwise enables IP spoofing past the pre-auth rate limit). /health does SELECT 1 against Postgres and returns 503 + status:unhealthy when the DB is unreachable so orchestration doesn't see green pods while clients get misleading 401s. Replaces the standalone OAuth wrapper that was vulnerable to unauthenticated client registration.
• src/commands/auth.ts — Token management for the HTTP transport. gbrain auth create/list/revoke/test. As of v0.22.7 wired into the main CLI (src/cli.ts); also runs standalone via bun run src/commands/auth.ts ... for environments without a compiled binary. Tokens stored as SHA-256 hashes in access_tokens (Postgres-only).
• 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.
• src/commands/migrations/ — TS migration registry (compiled into the binary; no filesystem walk of skills/migrations/*.md needed at runtime). index.ts lists migrations in semver order. v0_11_0.ts = Minions adoption orchestrator (8 phases). v0_12_0.ts = Knowledge Graph auto-wire orchestrator (5 phases: schema → config check → backfill links → backfill timeline → verify). phaseASchema has a 600s timeout (bumped from 60s in v0.12.1 for duplicate-heavy brains). v0_12_2.ts = JSONB double-encode repair orchestrator (4 phases: schema → repair-jsonb → verify → record). v0_14_0.ts = shell-jobs + autopilot cooperative (2 phases: schema ALTER minion_jobs.max_stalled SET DEFAULT 3 — superseded by v0.14.3's schema-level DEFAULT 5 + UPDATE backfill; pending-host-work ping for skills/migrations/v0.14.0.md). 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/integrity.ts — gbrain integrity check|auto|review|extract: bare-tweet detection, dead-link detection, three-bucket repair (auto-repair / review-queue / skip). scanIntegrity() is the shared library function called from gbrain doctor (sampled at limit=500) and cmdCheck (full scan). v0.22.8: batch-load fast path on Postgres uses SELECT DISTINCT ON (slug) in a single SQL query to fix the PgBouncer round-trip timeout (60s → ~6s) while preserving engine.getAllSlugs()'s Set<string> semantics on multi-source brains. Gated by engine.kind === 'postgres' at the call site so PGLite never enters batch; fallback catch logs at GBRAIN_DEBUG=1 so real Postgres errors are diagnosable.
• 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. v0.19.1 added queue_health (Postgres-only) with two subchecks: stalled-forever active jobs (started_at > 1h) and waiting-depth-per-name > threshold (default 10, override via GBRAIN_QUEUE_WAITING_THRESHOLD). Worker-heartbeat subcheck intentionally deferred to follow-up B7 because it needs a minion_workers table to produce ground-truth signal. Fix hints point at gbrain repair-jsonb, gbrain sync --force, gbrain apply-migrations, and gbrain jobs get/cancel <id>.
• 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. v0.22.6.1: migration v24 (rls_backfill_missing_tables) uses sqlFor: { pglite: '' } to no-op on PGLite — PGLite has no RLS engine and is single-tenant by definition, and the v24 ALTERs target subagent tables that don't exist in pglite-schema.ts. Closes #395 (contributed by @jdcastro2).
• 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. v0.22.1 (#403): CycleOpts.signal?: AbortSignal propagates the worker's abort signal; checkAborted() fires between every phase and throws if the signal is aborted (cooperative — can't interrupt a phase mid-execution). v0.22.1 (#417): runPhaseSync returns pagesAffected via SyncPhaseResult; runCycle captures it and threads to runPhaseExtract as the 4th arg, enabling incremental extract on the cycle path. v0.22.1 (Codex F2): runPhaseSync takes willRunExtractPhase: boolean and sets noExtract: phases.includes('extract') so gbrain dream --phase sync doesn't silently lose extraction. v0.22.5 (#475): new resolveSourceForDir(engine, brainDir) helper queries SELECT id FROM sources WHERE local_path = $1 LIMIT 1; runPhaseSync threads result as sourceId to performSync() so sync reads the per-source sources.last_commit anchor instead of the drift-prone global config.sync.last_commit key. Bare try/catch lets pre-v0.18 brains fall through to the global key. Closes the prod hang where every autopilot cycle ran a 30-min full reimport because the global anchor commit had been GC'd from git history.
• 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). Flags: --dry-run, --json, --phase <name>, --pull, --dir <path>. Exit code 1 on status=failed (partial/warn not fatal — don't page on warnings).
• scripts/check-progress-to-stdout.sh — CI guard against regressing to \r-on-stdout progress. Wired into bun run test via scripts/check-progress-to-stdout.sh && bun test in package.json.
• docs/progress-events.md — Canonical JSON event schema reference. Stable from v0.15.2, additive only.
• src/core/markdown.ts — Frontmatter parsing + body splitter. splitBody requires an explicit timeline sentinel (<!-- timeline -->, --- timeline ---, or --- immediately before ## Timeline/## History). Plain --- in body text is a markdown horizontal rule, not a separator. inferType auto-types /wiki/analysis/ → analysis, /wiki/guides/ → guide, /wiki/hardware/ → hardware, /wiki/architecture/ → architecture, /writing/ → writing (plus the existing people/companies/deals/etc heuristics).
• scripts/check-jsonb-pattern.sh — CI grep guard. Fails the build if anyone reintroduces (a) the ${JSON.stringify(x)}::jsonb interpolation pattern (postgres.js v3 double-encodes it), or (b) max_stalled INTEGER NOT NULL DEFAULT 1 in any schema source file (v0.15.1 #219 regression guard — must be DEFAULT 5 to preserve SIGKILL-rescue). Wired into bun test.
• scripts/llms-config.ts + scripts/build-llms.ts — Generator for llms.txt (llmstxt.org-spec web index) + llms-full.txt (inlined single-fetch bundle). Curated config drives both. Run bun run build:llms after adding a new doc. LLMS_REPO_BASE env var lets forks regenerate with their own URL base. FULL_SIZE_BUDGET (600KB) caps the inline bundle; generator WARNs if exceeded. Committed output is not analogous to schema-embedded.ts (no runtime consumer); we commit for GitHub browsing and fork-safe fetching.
• AGENTS.md — Local-clone entry point for non-Claude agents (Codex, Cursor, OpenClaw, Aider). Mirrors CLAUDE.md intent via relative links. Claude Code keeps using CLAUDE.md.
• docs/UPGRADING_DOWNSTREAM_AGENTS.md — Patches for downstream agent skill forks to apply when upgrading. Each release appends a new section. v0.10.3 includes diffs for brain-ops, meeting-ingestion, signal-detector, enrich.
• src/core/schema-embedded.ts — AUTO-GENERATED from schema.sql (run bun run build:schema)
• src/schema.sql — Full Postgres + pgvector DDL (source of truth, generates schema-embedded.ts)
• src/commands/integrations.ts — Standalone integration recipe management (no DB needed). Exports getRecipeDirs() (trust-tagged recipe sources), SSRF helpers (isInternalUrl, parseOctet, hostnameToOctets, isPrivateIpv4). Only package-bundled recipes are embedded=true; $GBRAIN_RECIPES_DIR and cwd ./recipes/ are untrusted and cannot run command/http/string health checks.
• src/core/search/expansion.ts — Multi-query expansion via Haiku. Exports sanitizeQueryForPrompt + sanitizeExpansionOutput (prompt-injection defense-in-depth). Sanitized query is only used for the LLM channel; original query still drives search.

Two lanes: shell jobs via gbrain jobs submit shell --params '{"cmd":"..."}' (operator/CLI only; MCP throws permission_denied for protected names) and LLM subagents via gbrain agent run (user-facing entrypoint). Shared Preconditions block, parent-child DAGs with depth/cap/timeouts, child_done inbox for fan-in, PGLite --follow inline path for dev. Triggers narrowed from bare "gbrain jobs" to "gbrain jobs submit" + "submit a gbrain job" so stats/prune/retry questions fall through to gbrain --help.

BrainBench — in a sibling repo (v0.20+)

BrainBench — the public benchmark for personal-knowledge agent stacks — lives in github.com/garrytan/gbrain-evals. It depends on gbrain as a consumer; gbrain never pulls in the ~5MB eval corpus or the pdf-parse dev dep at install time.

gbrain's public API surface (the exports map in package.json) is what gbrain-evals consumes: gbrain/engine, gbrain/types, gbrain/operations, gbrain/pglite-engine, gbrain/link-extraction, gbrain/import-file, gbrain/transcription, gbrain/embedding, gbrain/config, gbrain/markdown, gbrain/backoff, gbrain/search/hybrid, gbrain/search/expansion, gbrain/extract. Removing any of these is a breaking change for the gbrain-evals consumer.

Commands

Run gbrain --help or gbrain --tools-json for full command reference.

Key commands added in v0.7:

• gbrain init — defaults to PGLite (no Supabase needed), scans repo size, suggests Supabase for 1000+ files
• gbrain migrate --to supabase / gbrain migrate --to pglite — bidirectional engine migration

Key commands added for Minions (job queue):

• gbrain jobs submit <name> [--params JSON] [--follow] [--dry-run] — submit a background job. v0.13.1 adds first-class flags for every MinionJobInput tuning knob: --max-stalled N, --backoff-type fixed|exponential, --backoff-delay Nms, --backoff-jitter 0..1, --timeout-ms N, --idempotency-key K.
• gbrain jobs list [--status S] [--queue Q] — list jobs with filters
• gbrain jobs get <id> — job details with attempt history
• gbrain jobs cancel/retry/delete <id> — manage job lifecycle
• gbrain jobs prune [--older-than 30d] — clean old completed/dead jobs
• gbrain jobs stats — job health dashboard
• gbrain jobs smoke [--sigkill-rescue] — health smoke test. --sigkill-rescue is the v0.13.1 regression guard for #219: simulates a killed worker and asserts the stalled job is requeued instead of dead-lettered on first stall.
• gbrain jobs work [--queue Q] [--concurrency N] — start worker daemon (Postgres only)

Key commands added in v0.12.2:

• gbrain repair-jsonb [--dry-run] [--json] — repair double-encoded JSONB rows left over from v0.12.0-and-earlier Postgres writes. Idempotent; PGLite no-ops. The v0_12_2 migration runs this automatically on gbrain upgrade.

Key commands added in v0.12.3:

• gbrain orphans [--json] [--count] [--include-pseudo] — surface pages with zero inbound wikilinks, grouped by domain. Auto-generated/raw/pseudo pages filtered by default. Also exposed as find_orphans MCP operation. The natural consumer of the v0.12.0 knowledge graph layer: once edges are captured, find the gaps.
• gbrain doctor gains two new reliability detection checks: jsonb_integrity (v0.12.0 Postgres double-encode damage) and markdown_body_completeness (pages truncated by the old splitBody bug). Detection only; fix hints point at gbrain repair-jsonb and gbrain sync --force.

Key commands added in v0.14.2:

• gbrain sync --skip-failed — acknowledge the current set of failed-parse files recorded in ~/.gbrain/sync-failures.jsonl so the sync bookmark advances past them. Doctor's sync_failures check shows previously-skipped as "all acknowledged" instead of warning.
• gbrain sync --retry-failed — re-walk the unacknowledged failures and re-attempt parsing. If the files now succeed, they clear from the set and the bookmark advances naturally.
• gbrain apply-migrations --force-retry <version> — reset a wedged migration (3 consecutive partials with no completion) by appending a 'retry' marker. Next apply-migrations --yes treats the version as fresh. complete status never regresses to partial either before or after a retry marker.
• GBRAIN_POOL_SIZE env var — honored by both the singleton pool (src/core/db.ts) and the parallel-import worker pool (src/commands/import.ts). Default is 10; lower to 2 for Supabase transaction pooler to avoid MaxClients crashes during gbrain upgrade subprocess spawns. Read at call time via resolvePoolSize().
• gbrain doctor gains two new checks: sync_failures (surfaces unacknowledged parse failures with exact paths + fix hints) and brain_score (renders the 5-component breakdown when score < 100: embed coverage / 35, link density / 25, timeline coverage / 15, orphans / 15, dead links / 10 — sum equals total).

Key commands added in v0.14.3 (fix wave):

• gbrain doctor --index-audit — opt-in Postgres-only check reporting zero-scan indexes from pg_stat_user_indexes. Informational only; never auto-drops.
• gbrain doctor schema_version check fails loudly when version=0 — catches bun install -g github:... postinstall failures (#218) and routes users to gbrain apply-migrations --yes.
• gbrain jobs submit gains --max-stalled, --backoff-type, --backoff-delay, --backoff-jitter, --timeout-ms, --idempotency-key — exposing existing MinionJobInput fields as first-class CLI flags.
• gbrain jobs smoke --sigkill-rescue — opt-in regression smoke case simulating a killed worker; asserts the v0.14.3 schema default (max_stalled=5) actually rescues on first stall.

Testing

bun test runs all tests. After the v0.12.1 release: ~75 unit test files + 8 E2E test files (1412 unit pass, 119 E2E when DATABASE_URL is set — skip gracefully otherwise). Unit tests run without a database. E2E tests skip gracefully when DATABASE_URL is not set.

E2E tests (test/e2e/): Run against real Postgres+pgvector. Require DATABASE_URL.

• bun run test:e2e runs Tier 1 (mechanical, all operations, no API keys). Includes 9 dedicated cases for the postgres-engine addLinksBatch / addTimelineEntriesBatch bind path — postgres-js's unnest() binding is structurally different from PGLite's and gets its own coverage.
• test/e2e/search-quality.test.ts runs search quality E2E against PGLite (no API keys, in-memory)
• test/e2e/graph-quality.test.ts runs the v0.10.3 knowledge graph pipeline (auto-link via put_page, reconciliation, traversePaths) against PGLite in-memory
• test/e2e/postgres-jsonb.test.ts — v0.12.2 regression test. Round-trips all 5 JSONB write sites (pages.frontmatter, raw_data.data, ingest_log.pages_updated, files.metadata, page_versions.frontmatter) against real Postgres and asserts jsonb_typeof='object' plus ->>'key' returns the expected scalar. The test that should have caught the original double-encode bug.
• test/e2e/integrity-batch.test.ts (v0.22.8) — parity tests for scanIntegrity's batch-load fast path vs sequential. Four cases (dedup, hits, validate, topPages) seed a fixture and assert both paths return identical results. Dedup case uses raw SQL via getConn().unsafe() to seed a (test-source-2, people/alice) row alongside the default-source row, since engine.putPage doesn't take a source_id. Pins the codex-caught multi-source overcounting regression.
• test/e2e/jsonb-roundtrip.test.ts — v0.12.3 companion regression against the 4 doctor-scanned JSONB sites. Assertion-level overlap with postgres-jsonb.test.ts is intentional defense-in-depth: if doctor's scan surface ever drifts from the actual write surface, one of these tests catches it.
• test/e2e/upgrade.test.ts runs check-update E2E against real GitHub API (network required)
• test/e2e/minions-shell-pglite.test.ts (v0.20.4) exercises the PGLite --follow inline shell-job path (in-memory, no DATABASE_URL required) — the path the consolidated minion-orchestrator skill documents for dev use
• test/e2e/openclaw-reference-compat.test.ts (v0.19) — exercises check-resolvable + skillpack install against a minimal AGENTS.md workspace fixture (test/fixtures/openclaw-reference-minimal/), regression guard for the 107-skill OpenClaw deployment shape
• test/e2e/search-swamp.test.ts (v0.22.0) — reproduces the headline source-swamp case. Seeds a curated originals/talks/article-outline-fat-code page against two wintermute/chat/ pages stuffed with the same multi-word phrase. Asserts the article wins keyword AND vector ranking, that detail=high lets the chat swamp re-surface (temporal-query workflow preserved), and that source_id passes through the two-stage CTE intact. PGLite in-memory.
• test/e2e/search-exclude.test.ts (v0.22.0) — verifies test/ + archive/ pages are hidden by default, that include_slug_prefixes opts back in, and that caller-supplied exclude_slug_prefixes adds to defaults. Both keyword and vector search paths covered.
• test/e2e/engine-parity.test.ts (v0.22.0) — Postgres ↔ PGLite top-result and result-set parity for searchKeyword + searchVector. Codex flagged that Postgres ranks pages then picks best chunk while PGLite returns chunks directly — without parity coverage the source-boost fix could pass on PGLite and fail on Postgres. Skips gracefully when DATABASE_URL is unset.
• test/e2e/postgres-bootstrap.test.ts (v0.22.6.1) — exercises PostgresEngine.initSchema() directly against a fresh real Postgres database. Asserts the bootstrap path is no-op on fresh installs and that SCHEMA_SQL replays cleanly through the engine path (not via the standalone db.initSchema from src/core/db.ts, which would have produced false-positive coverage). Codex caught the E2E-shape gap during plan review.
• test/e2e/http-transport.test.ts (v0.22.7) — 8 cases against real Postgres covering gbrain serve --http end-to-end: bearer auth round-trip, last_used_at SQL-level debounce semantics, mcp_request_log row insertion on success and auth_failed paths, /health DB-down → 503 (DB-probing health check), and the F1+F2+F3 dispatch round-trip with a real operation. Skips gracefully when DATABASE_URL is unset.
• Tier 2 (skills.test.ts) requires OpenClaw + API keys, runs nightly in CI
• If .env.testing doesn't exist in this directory, check sibling worktrees for one: find ../ -maxdepth 2 -name .env.testing -print -quit and copy it here if found.
• Always run E2E tests when they exist. Do not skip them just because DATABASE_URL is not set. Start the test DB, run the tests, then tear it down.

API keys and running ALL tests

ALWAYS source the user's shell profile before running tests:

source ~/.zshrc 2>/dev/null || true

This loads OPENAI_API_KEY and ANTHROPIC_API_KEY. Without these, Tier 2 tests skip silently. Do NOT skip Tier 2 tests just because they require API keys — load the keys and run them.

When asked to "run all E2E tests" or "run tests", that means ALL tiers:

• Tier 1: bun run test:e2e (mechanical, sync, upgrade — no API keys needed)
• Tier 2: test/e2e/skills.test.ts (requires OpenAI + Anthropic + openclaw CLI)
• Always spin up the test DB, source zshrc, run everything, tear down.

E2E test DB lifecycle (ALWAYS follow this)

You are responsible for spinning up and tearing down the test Postgres container. Do not leave containers running after tests. Do not skip E2E tests.

1. Check for .env.testing — if missing, copy from sibling worktree. Read it to get the DATABASE_URL (it has the port number).
2. Check if the port is free: docker ps --filter "publish=PORT" — if another container is on that port, pick a different port (try 5435, 5436, 5437) and start on that one instead.
3. Start the test DB:

   docker run -d --name gbrain-test-pg \
     -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=postgres \
     -e POSTGRES_DB=gbrain_test \
     -p PORT:5432 pgvector/pgvector:pg16
   

   Wait for ready: docker exec gbrain-test-pg pg_isready -U postgres
4. Run E2E tests: DATABASE_URL=postgresql://postgres:postgres@localhost:PORT/gbrain_test bun run test:e2e
5. Tear down immediately after tests finish (pass or fail): docker stop gbrain-test-pg && docker rm gbrain-test-pg

Never leave gbrain-test-pg running. If you find a stale one from a previous run, stop and remove it before starting a new one.

Skills

Read the skill files in skills/ before doing brain operations. GBrain ships 29 skills organized by skills/RESOLVER.md (AGENTS.md is also accepted as of v0.19):

Original 8 (conformance-migrated): ingest (thin router), query, maintain, enrich, briefing, migrate, setup, publish.

Brain skills (ported from an upstream agent fork): signal-detector, brain-ops, idea-ingest, media-ingest, meeting-ingestion, citation-fixer, repo-architecture, skill-creator, daily-task-manager.

Operational + identity: daily-task-prep, cross-modal-review, cron-scheduler, reports, testing, soul-audit, webhook-transforms, data-research, minion-orchestrator. As of v0.20.4, minion-orchestrator is the single unified skill for both lanes of background work (shell jobs via gbrain jobs submit shell, LLM subagents via gbrain agent run) ... the prior gbrain-jobs skill was merged in, Preconditions are shared, and trigger routing is narrowed to what the skill actually covers.

Skillify loop (v0.19): skillify (the markdown orchestration), skillpack-check (agent-readable health report).

Operational health (v0.19.1): smoke-test (8 post-restart health checks with auto-fix for Bun, CLI, DB, worker, Zod CJS, gateway, API key, brain repo; user-extensible via ~/.gbrain/smoke-tests.d/*.sh).

Conventions: skills/conventions/ has cross-cutting rules (quality, brain-first, model-routing, test-before-bulk, cross-modal). skills/_brain-filing-rules.md and skills/_output-rules.md are shared references.

Bulk-action progress reporting

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.

Build

bun build --compile --outfile bin/gbrain src/cli.ts

Version locations (single source of truth: VERSION file)

Every release advances the version in five files at once. Keep these in sync. /ship enforces this via Step 12's idempotency check (VERSION vs package.json drift), but the canonical list lives here so future runs and the auto-update agent know where to look.

Required (every release must update all five):

File	What lives there	Format
VERSION	The single source of truth. Read first by /ship, the binary, and CI version-gate.	Bare 4-digit string MAJOR.MINOR.PATCH.MICRO (e.g. 0.22.1), no leading v, no trailing newline-sensitivity issues.
package.json	Bun/npm package version. gbrain --version reads it via the compiled binary's bundled package metadata. CI version-gate cross-checks this against VERSION and fails if they drift.	"version": "0.22.1"
CHANGELOG.md	Top entry header ## [0.22.1] - YYYY-MM-DD plus the "To take advantage of v0.22.1" block.	Standard Keep-a-Changelog header.
TODOS.md	Any TODO entries that mention "follow-up from vX.Y.Z" use the version of the release that filed them. Update only when filing NEW follow-up TODOs.	Inline vX.Y.Z references in TODO bodies.
CLAUDE.md	The Key Files section's per-file annotations carry vX.Y.Z (#NNN) tags noting which release introduced a behavior. Update whenever a wave's annotations get folded in.	Inline vX.Y.Z (#NNN, contributed by @user) references.

Auto-derived (no manual edit; refreshed by their own commands):

• bun.lock — root-package version is auto-pinned from package.json. After bumping package.json, run bun install to refresh the lockfile.
• llms-full.txt / llms.txt — auto-generated documentation bundles. After any release ship that touches the Key Files annotations in CLAUDE.md, run bun run build:llms to regenerate. The bundles do not contain a version pin per se; they reflect the current state of the docs they index.

Historical (DO NOT bump on release):

• skills/migrations/v0.21.0.md — migration files use the version they shipped FROM as their filename. v0.21.0's migration always says v0.21.0.
• src/commands/migrations/v0_21_0.ts — same: migration code references the schema version it migrates to.
• test/migrations-v0_21_0.test.ts, test/migration-orchestrator-v0_21_0.test.ts, test/migrate.test.ts — migration tests reference historical migration versions; these are correct as-is and should not move.
• src/core/db.ts, src/core/migrate.ts, src/core/import-file.ts, src/commands/reindex-code.ts — code comments cite the release that introduced a feature. Once written, these are historical record.
• README.md — references the latest published feature names by version (e.g. "v0.21.0 Code Cathedral"); update only when the README's marketing copy is intentionally being refreshed, NOT on every micro/patch bump.

The /ship workflow's version idempotency check: Step 12 reads VERSION and package.json, classifies as FRESH / ALREADY_BUMPED / DRIFT_STALE_PKG / DRIFT_UNEXPECTED, and refuses to proceed on DRIFT_UNEXPECTED. This is why the two must move together.

The CI version-gate rejects pushes where VERSION and package.json disagree, OR where VERSION is not strictly greater than master's VERSION. If a queue collision claims your version on master before yours lands, /ship's queue-aware allocator (Step 12) will detect drift and re-bump on the next run.

Pre-ship requirements

Before shipping (/ship) or reviewing (/review), always run the full test suite:

• bun test — unit tests (no database required)
• Follow the "E2E test DB lifecycle" steps above to spin up the test DB, run bun run test:e2e, then tear it down.

Both must pass. Do not ship with failing E2E tests. Do not skip E2E tests.

Post-ship requirements (MANDATORY)

After EVERY /ship, you MUST run /document-release. This is NOT optional. Do NOT skip it. Do NOT say "docs look fine" without running it. The skill reads every .md file in the project, cross-references the diff, and updates anything that drifted.

If /ship's Step 8.5 triggers document-release automatically, that counts. But if it gets skipped for ANY reason (timeout, error, oversight), you MUST run it manually before considering the ship complete.

Files that MUST be checked on every ship:

• README.md — does it reflect new features, commands, or setup steps?
• CLAUDE.md — does it reflect new files, test files, or architecture changes?
• CHANGELOG.md — does it cover every commit?
• TODOS.md — are completed items marked done?
• docs/ — do any guides need updating?

A ship without updated docs is an incomplete ship. Period.

CHANGELOG + VERSION are branch-scoped

VERSION and CHANGELOG describe what THIS branch adds vs master, not how we got here. Every feature branch that ships gets its own version bump and CHANGELOG entry. The entry is product release notes for users; it is not a log of internal decisions, review rounds, or codex findings.

Write the CHANGELOG entry at /ship time, not during development. Mid-branch iterations, review rounds (CEO/Eng/Codex/DX), and implementation detours belong in the plan file at ~/.claude/plans/, not in the CHANGELOG. One unified entry per branch, covering what the branch added vs the base branch.

Never edit a CHANGELOG entry that already landed on master. If master has v0.18.2 and your branch adds features, bump to the next version (v0.19.0, not editing master's v0.18.2). When merging master into your branch, master may bring new CHANGELOG entries above yours — push your entry above master's latest and verify:

• Does CHANGELOG have your branch's own entry separate from master's entries?
• Is VERSION higher than master's VERSION?
• Is your entry the topmost ## [X.Y.Z] entry?
• grep "^## \[" CHANGELOG.md shows a contiguous version sequence?

If any answer is no, fix it before continuing.

CHANGELOG is for users, not contributors. Write like product release notes:

• Lead with what the user can now do that they couldn't before. Sell the capability.
• Plain language, not implementation details. "You can now..." not "Refactored the..."
• Never mention internal artifacts: plan file IDs, decision tags (D-CX-#, F-ENG-#), review rounds, codex findings, subcontractor credits. These are invisible to users.
• Put contributor-facing changes in a separate ### For contributors section at the bottom.
• Every entry should make someone think "oh nice, I want to try that."

What to omit:

• "Codex caught X that the CEO review missed" — private process detail.
• "D-CX-3 split errors/warnings" — tag is meaningless to users; name the feature instead.
• "Fix-wave PR #N supersedes #M" — supersede chains belong in PR bodies, not release notes.
• "215 new cases, 3 decisions applied, 7 reviews cleared" — these are planning-mode metrics.

What to keep:

• The user-facing change: what commands exist now, what flag was added, what behavior fixed.
• Numbers that mean something to the user: TTHW, commands that timed out before, detection counts.
• Upgrade instructions: gbrain upgrade + any manual step if needed.
• Credit to external contributors when a community PR was incorporated.

CHANGELOG voice + release-summary format

Every version entry in CHANGELOG.md MUST start with a release-summary section in the GStack/Garry voice — one viewport's worth of prose + tables that lands like a verdict, not marketing. The itemized changelog (subsections, bullets, files) goes BELOW that summary, separated by a ### Itemized changes header.

The release-summary section gets read by humans, by the auto-update agent, and by anyone deciding whether to upgrade. The itemized list is for agents that need to know exactly what changed.

Release-summary template

Use this structure for the top of every ## [X.Y.Z] entry:

1. Two-line bold headline (10-14 words total) ... should land like a verdict, not marketing. Sound like someone who shipped today and cares whether it works.
2. Lead paragraph (3-5 sentences) ... what shipped, what changed for the user. Specific, concrete, no AI vocabulary, no em dashes, no hype.
3. A "The X numbers that matter" section with:
   • One short setup paragraph naming the source of the numbers (real production deployment OR a reproducible benchmark ... name the file/command to run).
   • A table of 3-6 key metrics with BEFORE / AFTER / Δ columns.
   • A second optional table for per-category breakdown if relevant.
   • 1-2 sentences interpreting the most striking number in concrete user terms.
4. A "What this means for [audience]" closing paragraph (2-4 sentences) tying the metrics to a real workflow shift. End with what to do.

Voice rules:

• No em dashes (use commas, periods, "...").
• No AI vocabulary (delve, robust, comprehensive, nuanced, fundamental, etc.) or banned phrases ("here's the kicker", "the bottom line", etc.).
• Real numbers, real file names, real commands. Not "fast" but "~30s on 30K pages."
• Short paragraphs, mix one-sentence punches with 2-3 sentence runs.
• Connect to user outcomes: "the agent does ~3x less reading" beats "improved precision."
• Be direct about quality. "Well-designed" or "this is a mess." No dancing.

Source material to pull from:

• CHANGELOG.md previous entry for prior context
• Latest gbrain-evals/docs/benchmarks/[latest].md for headline numbers (sibling repo)
• Recent commits (git log <prev-version>..HEAD --oneline) for what shipped
• Don't make up numbers. If a metric isn't in a benchmark or production data, don't include it. Say "no measurement yet" if asked.

Target length: ~250-350 words for the summary. Should render as one viewport.

"To take advantage of v[version]" block (required, v0.13+)

After the release-summary and BEFORE ### Itemized changes, every ## [X.Y.Z] entry MUST include a human-readable self-repair block under the heading ## To take advantage of v[version].

Why: gbrain upgrade runs gbrain post-upgrade which runs gbrain apply-migrations. This chain has a known weak link — upgrade.ts catches post-upgrade failures as best-effort (so the binary still works). When that chain silently fails, users end up with half-upgraded brains. The self-repair block gives them a paste-ready recovery path; the v0.13+ ~/.gbrain/upgrade-errors.jsonl trail + gbrain doctor integration close the loop.

Template (adapt the verify commands per release):

## To take advantage of v[version]

`gbrain upgrade` should do this automatically. If it didn't, or if `gbrain doctor`
warns about a partial migration:

1. **Run the orchestrator manually:**
   ```bash
   gbrain apply-migrations --yes

2. Your agent reads skills/migrations/v[version].md the next time you interact with it. [One sentence on whether headless agents need manual action, or whether the orchestrator already handled the mechanical side.]

3. Verify the outcome:

   [release-specific verify commands, e.g. `gbrain graph ... --depth 2`]
   gbrain stats
   

4. If any step fails or the numbers look wrong, please file an issue: https://github.com/garrytan/gbrain/issues with:

   • output of gbrain doctor
   • contents of ~/.gbrain/upgrade-errors.jsonl if it exists
   • which step broke

   This feedback loop is how the gbrain maintainers find fragile upgrade paths. Thank you.

**Skip this block** for patches that are pure bug fixes with zero user-facing action
(rare). If the release has a schema migration, data backfill, or new feature the
user needs to verify, the block is required.

The v0.13.0 entry in CHANGELOG.md is the canonical example.

### Itemized changes (the existing rules)

Below the release summary, write `### Itemized changes` and continue with the
detailed subsections (Knowledge Graph Layer, Schema migrations, Security hardening,
Tests, etc.). Same rules as before:

- Lead with what the user can now DO that they couldn't before
- Frame as benefits and capabilities, not files changed or code written
- Make the user think "hell yeah, I want that"
- Bad: "Added GBRAIN_VERIFY.md installation verification runbook"
- Good: "Your agent now verifies the entire GBrain installation end-to-end, catching
  silent sync failures and stale embeddings before they bite you"
- Bad: "Setup skill Phase H and Phase I added"
- Good: "New installs automatically set up live sync so your brain never falls behind"
- **Always credit community contributions.** When a CHANGELOG entry includes work from
  a community PR, name the contributor with `Contributed by @username`. Contributors
  did real work. Thank them publicly every time, no exceptions.

### Reference: v0.12.0 entry as canonical example

The v0.12.0 entry in CHANGELOG.md is the canonical example of the format. Match its
structure for every future version: bold headline, lead paragraph, "numbers that
matter" with BrainBench-style before/after table, "what this means" closer, then
`### Itemized changes` with the detailed sections below.

## Version migrations

Create a migration file at `skills/migrations/v[version].md` when a release
includes changes that existing users need to act on. The auto-update agent
reads these files post-upgrade (Section 17, Step 4) and executes them.

**You need a migration file when:**
- New setup step that existing installs don't have (e.g., v0.5.0 added live sync,
  existing users need to set it up, not just new installs)
- New SKILLPACK section with a MUST ADD setup requirement
- Schema changes that require `gbrain init` or manual SQL
- Changed defaults that affect existing behavior
- Deprecated commands or flags that need replacement
- New verification steps that should run on existing installs
- New cron jobs or background processes that should be registered

**You do NOT need a migration file when:**
- Bug fixes with no behavior changes
- Documentation-only improvements (the agent re-reads docs automatically)
- New optional features that don't affect existing setups
- Performance improvements that are transparent

**The key test:** if an existing user upgrades and does nothing else, will their
brain work worse than before? If yes, migration file. If no, skip it.

Write migration files as agent instructions, not technical notes. Tell the agent
what to do, step by step, with exact commands. See `skills/migrations/v0.5.0.md`
for the pattern.

## Migration is canonical, not advisory

GBrain's job is to deliver a canonical, working setup to every user on upgrade.
Anything that looks like a "host-repo change" — AGENTS.md, cron manifests,
launchctl units, config files outside `~/.gbrain/` — is a GBrain migration
step, not a nudge we leave for the host-repo maintainer. Migrations edit host
files (with backups) to make the canonical setup real. Exceptions: changes
that require human judgment (content edits, renames that break semantics,
host-specific handler registration where shell-exec would be an RCE surface).
Everything mechanical ships in the migration.

**Test:** if shipping a feature requires a sentence that starts with "in
your AGENTS.md, add…" or "in your cron/jobs.json, rewrite…", the migration
orchestrator should be doing that edit, not the user.

**The exception is host-specific code.** For custom Minion handlers
(host-specific integrations like inbox sweeps or third-party API scanners), shipping them as a
data file the worker would exec is an RCE surface. Those get registered in
the host's own repo via the plugin contract (`docs/guides/plugin-handlers.md`);
the migration orchestrator emits a structured TODO to
`~/.gbrain/migrations/pending-host-work.jsonl` + the host agent walks the
TODOs using `skills/migrations/v0.11.0.md` — stays host-agnostic, still
canonical.

## Privacy rule: scrub real names from public docs

**Never reference real people, companies, funds, or private agent names in any
public-facing artifact.** Public artifacts include: `CHANGELOG.md`, `README.md`,
`docs/`, `skills/`, PR titles + bodies, commit messages, and comments in checked-in
code. Query examples, benchmark stories, and migration guides MUST use generic
placeholders.

Why: gbrain runs a personal knowledge brain containing notes on real people and
real companies (YC founders, portfolio companies, funds, investors, meeting
attendees). When a doc copies a query like `gbrain graph diana-hu --depth 2` or
names a specific agent fork like `Wintermute`, that real name gets indexed by
search engines, surfaced in cross-references, and distributed with every release.

**Name mapping** to use in examples:
- Agent forks → `your agent fork`, `a downstream agent`, or `agent-fork`
- Example person → `alice-example`, `charlie-example`, or `a-founder`
- Example company → `acme-example`, `widget-co`, or `a-company`
- Example fund → `fund-a`, `fund-b`, `fund-c`
- Example deal → `acme-seed`, `widget-series-a`
- Example meeting → `meetings/2026-04-03` (generic date is fine)
- Example user → `you` or `the user`, never a proper name

**Specific rule: never say `Wintermute` in any CHANGELOG, README, doc, PR, or
commit message.** When the temptation is to illustrate with the real fork name:
- Reader-facing copy → `your OpenClaw` (covers Wintermute, Hermes, AlphaClaw,
  and any other downstream OpenClaw deployment in one term the reader already
  recognizes).
- First-person / origin-story copy → `Garry's OpenClaw` (honest that this is
  the production deployment driving the feature, without exposing the private
  agent's name).

`Wintermute` may appear in private artifacts (scratch plans under
`~/.gstack/projects/…`, memory files, conversation transcripts, CEO-review
plans) — those aren't distributed. Anything checked into this repo or shipped
in a release must use the OpenClaw phrasing above. Sweeping a stale reference
is a small clean-up PR, not a debate.

**When in doubt, ask yourself:** "Would this query reveal private information
about the user's contacts, investments, or portfolio if it were read by a
stranger?" If yes, replace with generic placeholders.

**Illustrative API examples with household-brand companies** (Stripe, Brex, OpenAI,
GitHub, etc.) are fine — they're public entities, not contacts in anyone's brain.
Do not confuse illustrative API examples with queries that reveal real
relationships.

## Responsible-disclosure rule: don't broadcast attack surface in release notes

**When a release fixes a security gap or a user-impacting bug, describe the fix
functionally. Do not enumerate the attack surface, quantify the exposure window,
or highlight the most sensitive records by name in public-facing artifacts.**

Public-facing artifacts include: `CHANGELOG.md`, `README.md`, `docs/`, PR titles
and bodies, commit messages, GitHub issue titles and comments, release pages,
tweets, blog posts.

**Don't write:**
- "10 tables were publicly readable by the anon key for months, including X, Y, Z"
- "X and Y are the most sensitive ones"
- "N tables exposed. Fix: enable RLS on these specific tables: ..."

**Do write:**
- "Security hardening pass. Fresh installs secure by default. Existing brains
  brought to the same bar automatically on upgrade."
- "If `gbrain doctor` still flags anything after upgrade, the message names each
  table and gives the exact fix."

Why: anyone reading the release page before they've upgraded now has a directed
probe list for unpatched installs. The source code ships the specifics anyway
(`src/schema.sql`, `src/core/migrate.ts`, test fixtures) — reverse engineers can
get them. But the release page is a broadcast channel. Don't hand attackers a
curated list with a banner.

**The test:** if a reader with no prior context could read the release note and
walk away knowing "gbrain at version X has table Y readable by anon key until
they patch," the note is too specific. Rewrite until that's no longer possible.

**What IS fine in public artifacts:**
- The mechanism of the fix ("the check now scans every public table instead of
  a hardcoded allowlist").
- User-facing operator ergonomics (the escape-hatch SQL template, the upgrade
  commands, the breaking-change flag).
- Credit to contributors.
- Generic framing of severity ("security posture tightening pass") without
  quantification.

**What stays in private artifacts (plan files, private memories, internal docs):**
- Specific table names, record counts, exposure duration.
- Which records stand out as highest-risk.
- Detailed before/after tables in the "numbers that matter" format.

If the CEO/Eng review of a plan produces a detailed exposure table, keep it in
the plan file under `~/.claude/plans/` or `~/.gstack/projects/`. Don't copy it
into the CHANGELOG or PR body.

Applies retroactively: if you see a prior CHANGELOG entry naming attack-surface
specifics, scrub it as a small cleanup commit, the same way a stale Wintermute
reference gets swept.

## Schema state tracking

`~/.gbrain/update-state.json` tracks which recommended schema directories the user
adopted, declined, or added custom. The auto-update agent (SKILLPACK Section 17)
reads this during upgrades to suggest new schema additions without re-suggesting
things the user already declined. The setup skill writes the initial state during
Phase C/E. Never modify a user's custom directories or re-suggest declined ones.

## GitHub Actions SHA maintenance

All GitHub Actions in `.github/workflows/` are pinned to commit SHAs. Before shipping
(`/ship`) or reviewing (`/review`), check for stale pins and update them:

```bash
for action in actions/checkout oven-sh/setup-bun actions/upload-artifact actions/download-artifact softprops/action-gh-release gitleaks/gitleaks-action; do
  tag=$(grep -r "$action@" .github/workflows/ | head -1 | grep -o '#.*' | tr -d '# ')
  [ -n "$tag" ] && echo "$action@$tag: $(gh api repos/$action/git/ref/tags/$tag --jq .object.sha 2>/dev/null)"
done

If any SHA differs from what's in the workflow files, update the pin and version comment.

PR descriptions cover the whole branch

Pull request titles and bodies must describe everything in the PR diff against the base branch, not just the most recent commit you made. When you open or update a PR, walk the full commit range with git log --oneline <base>..<head> and write the body to cover all of it. Group by feature area (schema, code, tests, docs) — not chronologically by commit.

This matters because reviewers read the PR body to understand what's shipping. If the body only covers your last commit, they miss everything else and can't review properly. A 7-commit PR with a body that describes commit 7 is worse than no body at all — it actively misleads.

When in doubt, run gh pr view <N> --json commits --jq '[.commits[].messageHeadline]' to see what's actually in the PR before writing the body.

Community PR wave process

Never merge external PRs directly into master. Instead, use the "fix wave" workflow:

1. Categorize — group PRs by theme (bug fixes, features, infra, docs)
2. Deduplicate — if two PRs fix the same thing, pick the one that changes fewer lines. Close the other with a note pointing to the winner.
3. Collector branch — create a feature branch (e.g. garrytan/fix-wave-N), cherry-pick or manually re-implement the best fixes from each PR. Do NOT merge PR branches directly — read the diff, understand the fix, and write it yourself if needed.
4. Test the wave — verify with bun test && bun run test:e2e (full E2E lifecycle). Every fix in the wave must have test coverage.
5. Close with context — every closed PR gets a comment explaining why and what (if anything) supersedes it. Contributors did real work; respect that with clear communication and thank them.
6. Ship as one PR — single PR to master with all attributions preserved via Co-Authored-By: trailers. Include a summary of what merged and what closed.

Community PR guardrails:

• Always AskUserQuestion before accepting commits that touch voice, tone, or promotional material (README intro, CHANGELOG voice, skill templates).
• Never auto-merge PRs that remove YC references or "neutralize" the founder perspective.
• Preserve contributor attribution in commit messages.

Skill routing

When the user's request matches an available skill, ALWAYS invoke it using the Skill tool as your FIRST action. Do NOT answer directly, do NOT use other tools first. The skill has specialized workflows that produce better results than ad-hoc answers.

NEVER hand-roll ship operations. Do not manually run git commit + push + gh pr create when /ship is available. /ship handles VERSION bump, CHANGELOG, document-release, pre-landing review, test coverage audit, and adversarial review. Manually creating a PR skips all of these. If the user says "commit and ship", "push and ship", "bisect and ship", or any combination that ends with shipping — invoke /ship and let it handle everything including the commits. If the branch name contains a version (e.g. v0.5-live-sync), /ship should use that version for the bump.

Key routing rules:

• Product ideas, "is this worth building", brainstorming → invoke office-hours
• Bugs, errors, "why is this broken", 500 errors → invoke investigate
• Ship, deploy, push, create PR, "commit and ship", "push and ship" → invoke ship
• QA, test the site, find bugs → invoke qa
• Code review, check my diff → invoke review
• Update docs after shipping → invoke document-release
• Weekly retro → invoke retro
• Design system, brand → invoke design-consultation
• Visual audit, design polish → invoke design-review
• Architecture review → invoke plan-eng-review
• Save progress, checkpoint, resume → invoke checkpoint
• Code quality, health check → invoke health
