ce15062694 feat: GBrain v0.7.0 — Integration Recipes + SKILLPACK Breakout (#39) 
* docs: break SKILLPACK into 17 individual guides

The 1,281-line SKILLPACK monolith is now 17 individually linkable guides
in docs/guides/, organized by category: core patterns, data pipelines,
operations, search, and administration.

GBRAIN_SKILLPACK.md becomes a structured index with categorized tables
linking to each guide. The URL stays stable for backward compatibility.

* docs: add integration guides, architecture docs, and ethos

New documentation directories:
- docs/integrations/ — "Getting Data In" landing page, credential gateway,
  meeting webhooks. Includes recipe format documentation.
- docs/architecture/ — Infrastructure layer doc (import, chunk, embed, search)
- docs/ethos/ — "Thin Harness, Fat Skills" essay with agent decision guide
- docs/designs/ — "Homebrew for Personal AI" 10-star vision document

* feat: add gbrain integrations command + voice-to-brain recipe

New CLI command: gbrain integrations (list/show/status/doctor/stats/test)
- Standalone command, no database connection needed
- Uses gray-matter directly for recipe parsing (not parseMarkdown)
- --json flag on every subcommand for agent-parseable output
- Bare command shows senses/reflexes dashboard
- Health heartbeat via ~/.gbrain/integrations/<id>/heartbeat.jsonl

First recipe: recipes/twilio-voice-brain.md
- Phone calls create brain pages via Twilio + OpenAI Realtime
- Opinionated defaults: caller screening, brain-first lookup, quiet hours
- Outbound call smoke test (GBrain calls the user to prove it works)
- Validate-as-you-go credential testing
- Twilio signature validation for webhook security

Migration file for v0.7.0 with agent-readable changelog.
13 unit tests covering parseRecipe, CLI routing, and recipe validation.

* docs: add Getting Data In to README, update CLAUDE.md and manifest

README: voice calls in intro bullet list, new "Getting Data In" section
with integration table (voice, email, X, calendar) and recipe philosophy.

CLAUDE.md: reference new files (integrations.ts, recipes/, docs/guides/,
docs/integrations/, docs/architecture/, docs/ethos/).

manifest.json: bump to v0.7.0, add recipes_dir field.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: v0.7.0 CHANGELOG, TODOS, VERSION bump

CHANGELOG: v0.7.0 entry covering integration recipes, voice-to-brain,
gbrain integrations command, SKILLPACK breakout, and new documentation.

TODOS: 3 new items from CEO/DX reviews (constrained health_check DSL,
community recipe submission, always-on deployment recipes).

VERSION + package.json: bump to 0.7.0.

* docs: rewrite voice recipe with agent instructions and verified links

Major improvements to recipes/twilio-voice-brain.md:

- Agent preamble: explains WHY sequential execution matters (each step
  depends on the previous), defines 4 stop points where the agent MUST
  pause and verify, tells agent to never say "something went wrong"
  but instead explain the exact error and fix

- User actions are now specific: exact URLs for every credential
  (Twilio console, OpenAI API keys page, ngrok dashboard), what
  buttons to click, what fields to copy, common failure modes

- All URLs verified via web search against current 2026 documentation:
  Twilio SID/token at twilio.com/console, OpenAI keys at
  platform.openai.com/api-keys, ngrok token at
  dashboard.ngrok.com/get-started/your-authtoken

- Cost estimate corrected: OpenAI Realtime is $0.06/min input +
  $0.24/min output (was understated), total ~$20-22/mo for 100 min

- Validate-as-you-go: each credential tested immediately with exact
  curl commands, failure messages explain what went wrong and how to fix

- Smoke test flow: tells user exactly what to say, verifies ALL
  three outputs (messaging notification + brain page + search result)

* docs: add "Homebrew for Personal AI" essay (markdown is code)

New essay at docs/ethos/MARKDOWN_SKILLS_AS_RECIPES.md — the distribution
corollary to "Thin Harness, Fat Skills." Argues that markdown skill files
are simultaneously documentation, specification, package, and source code.
The agent is the package manager. The git repo is the app store.

Referenced from SKILLPACK index and CLAUDE.md.

* docs: rewrite agent instructions as command language, promote skills

The OpenClaw/Hermes install block is now a drill sergeant, not a tour guide.
Every step is an imperative command with exact verification criteria and
explicit stop-on-failure behavior. No FYI, no suggestions, just rails.

Key changes:
- 11-step setup with STOP points after each step
- Exact user instructions for Supabase connection string (what to click,
  what NOT to give the agent, what the string looks like)
- "Verify: run X. You must see Y. If not: Z" after every step
- Skills table now links to both skill files AND guide docs
- Integration recipes table simplified (no "coming soon" placeholders)
- Docs section reorganized: for agents / for humans / reference

* fix: 4 codex findings + add email-to-brain recipe

Codex review found 4 issues, all fixed:

1. getStatus() returned "configured" if ANY secret was set (e.g. just
   OPENAI_API_KEY). Now requires ALL required secrets before marking
   configured. Prevents false "configured" status and spurious doctor runs.

2. Twilio health check hit unauthenticated endpoint (always 401). Now
   uses authenticated curl with SID:token, matching the setup validation.

3. README anchor docs/GBRAIN_SKILLPACK.md#the-dream-cycle broken after
   SKILLPACK rewrite. Updated to point to docs/guides/cron-schedule.md.

4. Compiled binary can't find recipes/ via import.meta.dir. Added
   GBRAIN_RECIPES_DIR env var override + global bun install path fallback.

Also adds recipes/email-to-brain.md: Gmail deterministic collector pattern
with ClawVisor credential gateway, validate-as-you-go, agent instructions.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add email, X, calendar, and meeting sync recipes

Four new integration recipes extracted from production wintermute patterns:

- recipes/email-to-brain.md: Gmail via ClawVisor, deterministic collector
  pattern (code pulls emails with baked-in links, agent does judgment),
  noise filtering, signature detection, digest generation

- recipes/x-to-brain.md: X API v2, timeline + mentions + keyword search,
  deletion detection (diffs previous run, verifies 404), engagement
  velocity tracking, rate limit awareness

- recipes/calendar-to-brain.md: Google Calendar via ClawVisor, historical
  backfill (years of data), daily markdown files with attendees + locations,
  attendee enrichment for brain pages

- recipes/meeting-sync.md: Circleback API, transcript import with speaker
  labels, attendee detection + filtering, entity propagation to people/
  company pages, action item extraction, idempotent by source_id

All recipes follow the same format: agent preamble with sequential execution
rules, validate-as-you-go credentials, exact URLs for API key setup,
stop-on-failure verification, and heartbeat logging.

Updated README, SKILLPACK index, and integrations landing page with all 5 recipes.

* docs: add Google OAuth as alternative to ClawVisor in email + calendar recipes

Both recipes now offer two auth options:
- Option A: ClawVisor (recommended, handles OAuth + token refresh)
- Option B: Google OAuth2 directly (no extra service, you manage tokens)

Option B includes step-by-step instructions for Google Cloud Console:
exact URLs, which buttons to click, which scopes to add, how to enable
the API, and the OAuth flow for token exchange.

This removes ClawVisor as a hard dependency for getting started.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: add implementation guides with pseudocode and test suggestions

Every recipe now includes an "Implementation Guide" section with:

- Production-tested pseudocode the agent can follow to build each collector
- Edge cases and failure modes discovered in real deployment
- Non-obvious implementation details (why the 48h staleness heuristic,
  why Gmail links need authuser, why SSE responses need double-parsing)
- Test suggestions: what the agent should verify after setup

email-to-brain: noise filtering algorithm, signature detection patterns,
  Gmail link generation (authuser is critical), sent-mail dedup

x-to-brain: deletion detection with 3 heuristics (7-day, 48h staleness,
  API verification), engagement velocity thresholds (50 min for 2x, 100
  absolute jump), atomic writes, stdout contract, rate limit handling

calendar-to-brain: smart chunking (monthly for sparse years, weekly for
  dense), attendee filtering (rooms, groups, distros), merge-with-existing
  (only replace ## Calendar section), date/time parsing edge cases

meeting-sync: SSE double-JSON parsing, idempotency double-check (grep +
  filename), auto-tagging from meeting names, git commit after sync

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: 6 new guides from production patterns (wintermute extraction)

New guides extracted and generalized from production deployment:

- repo-architecture.md: Two-repo pattern (agent behavior vs world knowledge).
  Strict boundary rules, decision tree, hard rule: never write knowledge
  to the agent repo.

- sub-agent-routing.md: Model routing table by task type. Signal detector
  pattern (spawn Sonnet on every message). Research pipeline pattern
  (Opus plans, DeepSeek executes, Opus synthesizes). Cost optimization.

- skill-development.md: 5-step cycle (concept, prototype, evaluate, codify,
  cron). MECE discipline (no overlapping skills). Quality bar checklist.
  "If you ask twice, it should already be a skill."

- idea-capture.md: Originality distribution rating (0-100 across 4
  populations). Depth test ("could someone unfamiliar understand WHY?").
  Deep cross-linking mandate. Notability filtering.

- quiet-hours.md: Hold notifications 11pm-8am local time. Held messages
  directory pattern. Timezone-aware delivery. Morning briefing pickup.

- diligence-ingestion.md: 9-step pipeline for data room materials. Detection
  patterns (PDF filenames, spreadsheet tabs, user language). Index.md
  template with bull/bear case. Company page enrichment.

All PII scrubbed. Patterns generalized for any user.
SKILLPACK index updated with 6 new entries. CLAUDE.md references added.
All 37 SKILLPACK links verified.

* docs: upgrade all guides to operational playbooks with pseudocode

Every guide now follows the playbook structure:
- Goal: one sentence, what this achieves
- What the User Gets: without this / with this
- Implementation: pseudocode with actual gbrain commands
- Tricky Spots: production-tested gotchas
- How to Verify: test steps the agent runs after setup

Guides upgraded (15 files):
- brain-agent-loop: on_message() loop with read/write/sync pseudocode
- brain-first-lookup: 4-step lookup cascade with exact commands
- brain-vs-memory: routing algorithm for 3 knowledge layers
- compiled-truth: page structure + rewrite vs append rules
- content-media: 3 ingest patterns (YouTube, social, PDFs)
- cron-schedule: full schedule table + dream cycle pseudocode
- enrichment-pipeline: 7-step protocol with tier classification
- entity-detection: spawn pattern + detection prompt + notability filter
- executive-assistant: 3 workflow algorithms (triage, prep, post-inbox)
- meeting-ingestion: 6-step transcript-to-brain flow
- operational-disciplines: 5 executable discipline blocks
- originals-folder: detection + exact-phrasing capture + cross-linking
- search-modes: decision tree for keyword vs hybrid vs direct
- source-attribution: citation format + hierarchy + conflict resolution
- Plus Goal/What User Gets headers on 6 newer guides

* docs: add WebRTC to voice recipe + ngrok Hobby setup guide

Voice recipe updates:
- Added WebRTC endpoint (POST /session, GET /call, POST /tool) for
  browser-based calling with RNNoise noise suppression
- WebRTC pseudocode with the 4 non-obvious gotchas from production
  (voice under audio.output.voice, no turn_detection, no session.update
  on connect, trigger greeting via data channel)
- Recommend ngrok Hobby ($8/mo) for fixed domain instead of free tier
- Fixed domain means URLs never change, Twilio never breaks

New guide: docs/mcp/NGROK_SETUP.md
- How to set up ngrok Hobby for both MCP and voice agent
- Fixed domain setup, watchdog pattern, AI client configuration
- Claude Desktop requires Settings > Integrations (not JSON config)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add dependency graph + ngrok-tunnel + credential-gateway recipes

Recipes now have real dependencies via the `requires` field:
- voice-to-brain requires ngrok-tunnel (needs public URL for Twilio)
- email-to-brain requires credential-gateway (needs Gmail access)
- calendar-to-brain requires credential-gateway (needs Calendar access)
- x-to-brain and meeting-sync are standalone (direct API keys)

Two new infrastructure recipes:
- ngrok-tunnel: fixed public URL for MCP + voice. Recommends Hobby
  ($8/mo) for a domain that never changes. Includes watchdog pattern.
- credential-gateway: secure Google service access via ClawVisor
  (recommended) or direct OAuth2. One setup, all Google recipes use it.

Moved ngrok from docs/mcp/ to recipes/ — it's shared infrastructure,
not MCP-specific.

README and integrations landing page show dependency chains.
When agent installs voice-to-brain, it sets up ngrok-tunnel first.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: add infra category, fix dashboard alignment, show dependencies

DX audit found two bugs in gbrain integrations dashboard:

1. Column alignment broken — IDs > 18 chars ran into descriptions
   with no space. Fixed: pad to 22 chars.

2. ngrok-tunnel and credential-gateway showed as SENSES but they're
   infrastructure. Added 'infra' category. Dashboard now shows three
   sections: INFRASTRUCTURE (set up first), SENSES, REFLEXES.

3. Dependencies now shown inline: "AVAILABLE (needs credential-gateway)"

Also added 'requires' field to JSON output for agent consumption.

* docs: add frontier model requirement disclaimer to README

GBrain's markdown-is-code approach requires models capable of
interpreting intent and implementing from architecture descriptions.
Tested with Claude Opus 4.6 and GPT-5.4 Thinking. Smaller models
will struggle with the recipe format.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: add PGLite → Supabase upgrade path to README

Clarify the database progression: start with PGLite (Postgres as WASM,
zero infrastructure, pgvector built in, nothing to install). Graduate
to Supabase or self-hosted Postgres when you need connection pooling,
concurrency, and remote MCP access from Claude Desktop, Cowork,
ChatGPT, Perplexity Computer, or any MCP-compatible agent.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: revert PGLite mention (coming in next branch)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: make all 23 guides consistent (Goal/Impl/Tricky/Verify)

Every guide now has exactly these sections in this order:
- ## Goal (one sentence)
- ## What the User Gets (without this / with this)
- ## Implementation (pseudocode with gbrain commands)
- ## Tricky Spots (3-5 numbered gotchas)
- ## How to Verify (3-5 numbered test steps)

11 guides restructured from non-standard headings:
- deterministic-collectors, live-sync, upgrades-auto-update (full rewrites)
- entity-detection, diligence-ingestion, idea-capture, quiet-hours,
  repo-architecture, skill-development, sub-agent-routing (restructured)

23/23 guides now pass consistency audit.

* docs: restructure README around the #1 blocker (getting data in)

The README was leading with Postgres and database architecture. Most
users are stuck at step zero: "I have an agent but it doesn't know
anything about my life."

New structure:
1. The Problem — your agent doesn't know your life
2. Getting Data In — integration recipes, front and center
3. The Compounding Thesis — why this matters
4. How this happened — credibility, origin story
5. When you need Postgres — scale, not starting point

Postgres is de-emphasized from a full section to two paragraphs:
"You don't need Postgres to start" and "When you need Postgres"
(1,000+ files, remote MCP access, multiple AI clients).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: move Install to top of README, remove duplicate section

Install now appears right after Getting Data In (line 38), not buried
at line 295. The user sees: Problem → Getting Data In → Install.

Removed the duplicate Install section (262 lines) that was lower in
the README. The agent instructions block, CLI quickstart, and all
content is now in the single Install section near the top.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: move agent install block to first thing in README

"Start here: paste this into your agent" is now the first section,
right after the one-line pitch. No scrolling, no context, no preamble.
User opens the README, sees the paste block, copies it into OpenClaw
or Hermes, and the agent takes over.

Flow: pitch → paste block → Getting Data In → Compounding Thesis → origin story

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: compress install block from 11 steps to 5

The agent install block was 102 lines and 11 steps. Now it's 40 lines
and 5 steps. Same coverage, half the text.

Changes:
- Merged "prove keyword search" + "embed" + "prove hybrid search"
  into one SEARCH step (the user doesn't care about the intermediate)
- Merged skillpack, sync, auto-update, integrations, verification
  into one GO LIVE step with sub-items (post-install polish, not install)
- Shortened database instructions (one line instead of 5 sub-steps)
- Removed redundant preamble ("YOU MUST COMPLETE EVERY STEP" is now
  just "Do not skip steps. Verify each step.")

The 5 steps: INSTALL → DATABASE → IMPORT → SEARCH → GO LIVE

* security: gitignore all .env files, not just specific ones

CSO audit found .gitignore covered .env.testing and .env.production
but not bare .env. A user creating .env with database credentials
could accidentally commit it.

Fix: .env and .env.* are now gitignored. .env.*.example files are
explicitly un-ignored so templates remain tracked.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* security: scrub PII from essay and recipe examples

- 510-MY-GARRY phone mnemonic → "Your Phone Number"
- "Garry → Authenticated Mode" → "Owner → Authenticated Mode"
- "Telegram" → "secure channel" in auth example
- @garrytan → @yourhandle in X recipe example

3e21e9b69b feat: GBrain v0.6.0 — Remote MCP Server + 12 Bug Fixes (#28) 
* fix: 7 bug fixes from Issue #9 and #22

- fix(mcp): use ListToolsRequestSchema/CallToolRequestSchema instead of string literals (Issue #9, PR #25)
- fix(mcp): handleToolCall reads dry_run from params instead of hardcoding false (#22 Bug #11)
- fix(search): keyword search returns best chunk per page via DISTINCT ON, not all chunks (#22 Bug #8)
- fix(search): dedup layer 1 keeps top 3 chunks per page instead of collapsing to 1 (#22 Bug #12)
- fix(engine): transaction uses scoped engine via Object.create, no shared state mutation (#22 Bug #2)
- fix(engine): upsertChunks uses UPSERT instead of DELETE+INSERT, preserves existing embeddings (#22 Bug #1)
- fix(slugs): validateSlug normalizes to lowercase, pathToSlug lowercases consistently (#22 Bug #4)
- schema: add unique index on content_chunks(page_id, chunk_index) for UPSERT support
- schema: add access_tokens and mcp_request_log tables via migration

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: embed schema.sql at build time, remove fs dependency from initSchema

initSchema() previously read schema.sql from disk at runtime via readFileSync,
which broke in compiled Bun binaries and Deno Edge Functions. Now uses a
generated schema-embedded.ts constant (run `bun run build:schema` to regenerate).

- Removes fs and path imports from postgres-engine.ts and db.ts
- Adds scripts/build-schema.sh for one-source-of-truth generation
- Adds build:schema npm script

Fixes Issue #22 Bug #6.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: 5 more bug fixes from Issue #22

- fix(file_upload): call storage.upload() in all 3 paths (operation, CLI upload, CLI sync) with rollback semantics (#22 Bug #9)
- fix(import): use atomic index counter for parallel queue instead of array.shift() race, preserve checkpoint on errors (#22 Bug #3)
- fix(s3): replace unsigned fetch with @aws-sdk/client-s3 for proper SigV4 auth, supports R2/MinIO via forcePathStyle (#22 Bug #10)
- fix(redirect): verify remote file exists before deleting local copy, skip files not found in storage (#22 Bug #5)
- deps: add @aws-sdk/client-s3

* feat: remote MCP server via Supabase Edge Functions

Deploy GBrain as a serverless remote MCP endpoint on your existing Supabase
instance. One brain, accessible from Claude Desktop, Claude Code, Cowork,
Perplexity Computer, and any MCP client. Zero new infrastructure.

New files:
- supabase/functions/gbrain-mcp/index.ts — Edge Function with Hono + MCP SDK
- supabase/functions/gbrain-mcp/deno.json — Deno import map
- src/edge-entry.ts — curated bundle entry point (excludes fs-dependent modules)
- src/commands/auth.ts — standalone token management (create/list/revoke/test)
- scripts/deploy-remote.sh — one-script deployment
- .env.production.example — 3-value config template

Changes:
- config.ts: lazy-evaluate CONFIG_DIR (no homedir() at module scope)
- schema.sql: add access_tokens + mcp_request_log tables
- package.json: add build:edge script

Auth: bearer tokens via access_tokens table (SHA-256 hashed, per-client, revocable)
Transport: WebStandardStreamableHTTPServerTransport (stateless, Streamable HTTP)
Health: /health endpoint (unauth: 200/503, auth: postgres/pgvector/openai checks)
Excluded from remote: sync_brain, file_upload (may exceed 60s timeout)

Setup: clone, fill .env.production, run scripts/deploy-remote.sh, create token, done.

* docs: per-client MCP setup guides

- docs/mcp/DEPLOY.md — deployment walkthrough, auth, troubleshooting, latency table
- docs/mcp/CLAUDE_CODE.md — claude mcp add command
- docs/mcp/CLAUDE_DESKTOP.md — Settings > Integrations (NOT JSON config!)
- docs/mcp/CLAUDE_COWORK.md — remote + local bridge paths
- docs/mcp/PERPLEXITY.md — Perplexity Computer connector setup

GBrain v0.6.0: Remote MCP server via Supabase Edge Functions + 12 bug fixes.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: add Remote MCP Server section to README

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: make document-release mandatory in CLAUDE.md, add MCP key files

Post-ship requirements section: document-release is NOT optional. Lists every
file that must be checked on every ship. A ship without updated docs is incomplete.

Also adds remote MCP server files to Key files section.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: batch upsertChunks into single statement to prevent deadlocks

The per-chunk UPSERT loop caused deadlocks under parallel workers because
each INSERT ON CONFLICT acquired row-level locks sequentially. Multiple
workers upserting different pages could deadlock on the shared unique index.

Fix: batch all chunks into a single multi-row INSERT ON CONFLICT statement.
One round-trip, one lock acquisition. COALESCE preserves existing embeddings
when the new value is NULL.

Fixes CI failure: "E2E: Parallel Import > parallel import with --workers 4"

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: advisory lock in initSchema() prevents deadlock on concurrent DDL

When multiple processes call initSchema() concurrently (e.g., test setup +
CLI subprocess, or parallel workers during E2E tests), the schema SQL's
DROP TRIGGER + CREATE TRIGGER statements acquire AccessExclusiveLock on
different tables, causing deadlocks.

Fix: pg_advisory_lock(42) serializes all initSchema() calls within the
same database. The lock is session-scoped and released in a finally block.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: add explicit test timeouts for CLI subprocess E2E tests

CLI subprocess tests (Setup Journey, Doctor Command, Parallel Import)
spawn `bun run src/cli.ts` which takes several seconds to JIT compile +
connect. The Bun test framework default 5000ms per-test timeout is too
tight for CI. Added 30-60s timeouts matching each subprocess's own
timeout to prevent false failures.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: infinite recursion in config.ts exported getConfigDir/getConfigPath

The replace_all refactor created recursive functions: the exported
getConfigDir() called the private getConfigDir() which called itself.
Renamed exports to configDir()/configPath() to avoid shadowing.

Also adds scripts/smoke-test-mcp.ts — verified all 8 MCP tool calls
work against a real Postgres database.

Deferred from security audit. S3 storage backend accepts credentials
but sends unsigned requests. Implement when S3 becomes a real
deployment path.

912a321cfa GBrain v0.4.0 — production agent documentation + reference architecture (#10) 
* fix: widen validateSlug to accept any filename characters

Git is the system of record. Slugs are lowercased repo-relative paths.
The restrictive regex rejected spaces, parens, and special chars, blocking
5,861 Apple Notes files from importing. Now only rejects empty slugs,
path traversal (..), and leading slash.

* feat: enable RLS on all tables with BYPASSRLS safety check

Without RLS, the Supabase anon key gives full read access to the DB.
Enable RLS on all 10 tables with no policies — the postgres role
(used by gbrain via pooler) has BYPASSRLS and is unaffected. Only
enables if the current role actually has BYPASSRLS privilege to
avoid locking ourselves out on non-Supabase setups.

* fix: import resilience — 5MB limit, error suppression, structured progress

Raise MAX_FILE_SIZE from 1MB to 5MB for Apple Notes with attachments.
Track error patterns and suppress after 5 identical errors to prevent
5,861 identical warnings from killing the agent process. Replace \r
progress bar with structured log lines (rate, ETA) for agent parsing.

* fix: init detects IPv6-only Supabase URLs, adds pgvector check

Detect db.*.supabase.co direct URLs and warn about IPv6 failure.
On ECONNREFUSED/ETIMEDOUT to Supabase, suggest the Session pooler
connection string with exact dashboard click path. Check for pgvector
extension after connecting and fail with clear instructions if missing.
Update wizard hints to show pooler URL format.

* docs: add pre-ship requirement for E2E tests

E2E tests against real Postgres+pgvector must pass before /ship or
/review. Adds the requirement to CLAUDE.md so all agents enforce it.

* feat: parallel import with per-worker engine instances

Refactor PostgresEngine to support instance-level DB connections instead
of only the module-global singleton. Each worker gets its own connection
with poolSize:2 (vs 10 for the main engine), so 8 workers = 16 connections.

Add --workers N flag to gbrain import. Workers pull from a shared queue
and use independent engine instances — no transaction context corruption.

The bottleneck is network round-trips to Supabase (one per page upsert).
Parallel workers cut import time proportionally.

* feat: automatic schema migration runner

Migrations are embedded as string constants in migrate.ts (survives
Bun --compile). Each migration runs in a transaction for clean rollback
on failure. Runs automatically on initSchema() — no manual step needed
when a user updates the gbrain binary against an older DB.

* feat: pluggable storage backend (S3 + Supabase Storage + local)

Add StorageBackend interface with three implementations:
- S3Storage: works with AWS S3, Cloudflare R2, MinIO (any S3-compatible)
- SupabaseStorage: uses Supabase Storage REST API with service role key
- LocalStorage: filesystem-based, for testing

Add file-resolver.ts with fallback chain: local file → .redirect
breadcrumb → .supabase marker → storage backend. Supports the
three-stage migration (mirror → redirect → clean).

Add yaml-lite.ts for parsing marker and breadcrumb files without
adding a YAML dependency.

* feat: gbrain doctor command — health checks with --json output

Checks: connection, pgvector extension, RLS on all tables, schema
version, embedding coverage. Outputs structured JSON with --json flag
for agent parsing. Exit code 0 if healthy, 1 if issues found.

Agents should run gbrain doctor --json when any command fails.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: rewrite setup skill + README for agent-first DX

Setup skill: add Why Supabase, step-by-step project creation, explicit
agent instructions (nohup for large imports, doctor on failure, don't
ask for anon key), available init flags, file migration offer after
first import. Remove ClawHub references.

README: simplify to single OpenClaw install path, remove ClawHub, fix
squatted npm name to github:garrytan/gbrain, add Supabase settings
note about Session pooler.

Add Apple Notes test fixtures with spaces and parens in filenames for
E2E testing of the slug fix.

* docs: add RLS verification, schema health, and nohup hints to maintain skill

Maintenance skill now checks RLS status and schema version as part of
periodic health checks. Adds nohup pattern for large embedding refreshes.

* feat: import resume checkpoint + Supabase smart URL parsing

Import resume: saves checkpoint every 100 files to ~/.gbrain/import-checkpoint.json.
On restart with same directory and file count, skips already-processed files.
Use --fresh to ignore checkpoint and start over. Cleared on successful completion.

Supabase admin: extractProjectRef() parses any Supabase URL format (dashboard,
direct, pooler, project URL) to extract the project ref. discoverPoolerUrl()
uses the Management API to find the correct pooler connection string (including
the exact region prefix). checkRls() verifies RLS status via the API.

* test: add 56 unit tests for all new code

8 new test files covering every feature added in this branch:
- slug-validation.test.ts: spaces, parens, unicode, path traversal (10 tests)
- yaml-lite.test.ts: parse + stringify, marker/redirect formats (9 tests)
- supabase-admin.test.ts: extractProjectRef for 4 URL formats (7 tests)
- migrate.test.ts: version export, runMigrations callable (2 tests)
- storage.test.ts: LocalStorage CRUD + createStorage factory (14 tests)
- file-resolver.test.ts: fallback chain, redirect, marker parsing (6 tests)
- import-resume.test.ts: checkpoint save/load/resume/fresh (6 tests)
- doctor.test.ts: module export, CLI registration (3 tests)

Total: 184 pass, 0 fail (up from 128).

* feat: bulk chunk INSERT + E2E tests for all new features

Bulk INSERT: upsertChunks now builds a multi-row VALUES query instead
of inserting chunks one-by-one. Reduces DB round-trips by ~50x per page.

E2E tests added to mechanical.test.ts:
- Slug with special chars: import Apple Notes fixtures with spaces/parens,
  verify search finds them, verify idempotency
- RLS verification: check pg_tables.rowsecurity on all tables, verify
  current user has BYPASSRLS
- Doctor command: verify exit 0 on healthy DB, --json produces valid JSON
  with check structure
- Parallel import: --workers 2 produces same page count as sequential

Unit tests added:
- setup-branching.test.ts: IPv6 detection, defaultWorkers auto-tuning,
  smart URL parsing across all Supabase URL formats

Fixtures added:
- large/big-file.md (2.1MB) for testing raised file size limit
- apple-notes/ fixtures already existed

Total: 200 pass, 0 fail (up from 184).

* feat: --json on init/import, file migration CLI, lifecycle tests

--json flag: init and import now support --json for structured output.
Agents get parseable JSON instead of human-readable text.

File migration CLI: implement mirror, unmirror, redirect, restore,
clean, and status subcommands for the three-stage file migration
lifecycle (local → mirrored → redirected → cloud-only).

File migration tests: full lifecycle test covering every transition
in the state machine (LOCAL → MIRROR → UNMIRROR → REDIRECT → RESTORE
→ CLEAN), including edge cases and file resolver at each stage.

Bulk chunk INSERT: upsertChunks now builds multi-row parameterized
VALUES query, reducing round-trips per page from ~50 to 1.

Total: 207 pass, 0 fail.

* test: thorough E2E tests for parallel import concurrency

Replace the weak single-comparison parallel import test with 7 tests:
- Sequential baseline: capture page count, chunk count, and all slugs
- --workers 2: verify page count matches sequential
- Chunk count matches (no duplicates from concurrent writes)
- Page slugs match exactly
- No duplicate pages (SQL GROUP BY HAVING count > 1)
- No duplicate chunks (SQL GROUP BY page_id, chunk_index)
- --workers 4: also works correctly
- Re-import with workers is idempotent

These tests catch the exact bug Codex found (db.ts singleton causing
concurrent transaction corruption) by verifying data integrity after
parallel writes.

* docs: add batch embedding queue as P1 TODO

Deferred during eng review (per-worker embedding is good enough for now).
Revisit after profiling real imports to confirm embedding is the bottleneck.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: E2E test failures — fixture counts, arg parsing, doctor exit code

Fix fixture count assertions: 13 → 16 pages (added apple-notes + large file),
companies 2 → 3 (ohmygreen), concepts 3 → 5 (notes, big-file).

Fix --workers arg parsing: the worker count value (e.g. "2") was being
picked up as the directory arg. Skip flag values when finding the dir.

Fix doctor exit code: warnings (like missing embeddings) should exit 0,
only actual failures exit 1. E2E tests import with --no-embed, so
embeddings are always WARN.

Fix E2E CLI tests: add initCli() before doctor and parallel import
tests so ~/.gbrain/config.json exists for the subprocess.

All E2E tests pass: 63 pass, 0 fail.
All unit tests pass: 207 pass, 0 fail.

* docs: update project documentation for v0.4.0

New CHANGELOG entry for all post-0.3.0 features (doctor, storage backends,
parallel import, resume checkpoints, RLS, schema migrations, --json output).
Version bumped 0.3.0 → 0.4.0 across all manifests.

CLAUDE.md: test count 9→19, skill count 8→7, added key files.
CONTRIBUTING.md: fixture count 13→16, added missing source files.
README.md: added gbrain doctor to commands, fixed stale welcome PRs.

* docs: add GBRAIN_SKILLPACK.md reference architecture

Production agent patterns from a real deployment with 14,700+ brain files.
Covers: entity detection on every message, brain-first lookup protocol,
7-step enrichment pipeline with tiered API spend, compiled truth + timeline,
source attribution with mandatory citations, meeting ingestion with entity
propagation, cron schedule with quiet hours and travel-aware timezone,
YouTube/media ingestion via Diarize.io, integration guides for ClawVisor,
Circleback webhooks, and Quo/OpenPhone SMS. Opens with the Vannevar Bush
memex framing and the originals folder for capturing intellectual capital.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: rewrite README opener with memex pitch and production architecture

Replace code-first opener with mimetic-desire pitch: Vannevar Bush memex
tagline, production brain numbers (10K+ files, 3K+ people, 13 years of
calendar), "ask it anything" examples, compounding thesis.

New sections: The Compounding Thesis (read-write loop), Architecture
(three-column diagram), What a Production Agent Looks Like (SKILLPACK
reference), How gbrain fits with OpenClaw (three-layer complement).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: update skills with brain-first lookup, entity detection, heartbeat

setup: Phase D rewritten with brain-first lookup protocol (gbrain search
→ query → get → grep fallback), sync-after-write rule, memory_search
complement table.

query: token-budget awareness (chunks not full pages), source precedence
hierarchy (user > compiled truth > timeline > external).

ingest: entity detection on every message (scan, check brain, create or
enrich, commit and sync).

maintain: heartbeat integration (doctor, embed --stale, sync verification,
stale compiled truth detection).

briefing: gbrain-native context loading (search attendees before meetings,
search sender before email, daily deal/meeting/commitment queries).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: add OpenClaw positioning to README opener

Make it clear up top that GBrain is built for OpenClaw agents and
works with any OpenClaw deployment.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: credit Karpathy's Knowledge LLM vision, add origin story

GBrain started as Karpathy's LLM wiki idea built for real. Worked great
until the brain hit thousands of files and grep fell apart. GBrain is the
search layer that had to exist once the brain outgrew grep.
