 		a86f995883 feat: GBrain v0.3.0 — contract-first architecture + ClawHub plugin (#7) 
* feat: contract-first operations.ts with OperationError, dry_run, importFromContent

30 shared operations as single source of truth for CLI and MCP.
- OperationError with typed error codes (page_not_found, invalid_params, etc.)
- dry_run support on all mutating operations
- importFromContent split from importFile with transaction wrapping
- Idempotency hash now includes ALL fields (title, type, frontmatter, tags)
- Config env var fallback: GBRAIN_DATABASE_URL > DATABASE_URL > config file

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

* refactor: rewrite MCP server + CLI + tools-json from operations

server.ts: 233 -> ~80 lines. Tool definitions and dispatch generated from operations[].
cli.ts: shared operations auto-registered, CLI-only commands kept as manual dispatch.
tools-json: generated FROM operations[], eliminating the third contract surface.
Parity test verifies structural contract between operations, CLI, and MCP.

* refactor: delete 12 command files migrated to operations.ts

Handler logic for get, put, delete, list, search, query, health, stats,
tags, link, timeline, and version now lives in operations.ts.
Kept: init, upgrade, import, export, files, embed, sync, serve, call, config.

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

* feat: init --non-interactive, upgrade verification, schema migration

- gbrain init --non-interactive --url <url> for plugin mode (no TTY required)
- Post-upgrade version verification in gbrain upgrade
- Drop storage_url from files table (storage_path is the only identifier)

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

* feat: tool-agnostic skills + new setup skill

All 7 skills rewritten with intent-based language instead of CLI commands.
Works with both CLI and MCP plugin contexts.
New setup skill replaces install: auto-provision Supabase via CLI,
AGENTS.md injection, target TTHW < 2 min.

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

* feat: ClawHub bundle plugin, CI workflows, v0.3.0

- openclaw.plugin.json with configSchema, MCP server config, skill listing
- GitHub Actions: test on push/PR, multi-platform release (macOS arm64 + Linux x64)
- Version bump 0.3.0, CHANGELOG, README ClawHub section, CLAUDE.md updated

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

* fix: idempotency hash mismatch + MCP dry_run passthrough

importFromContent now passes its all-fields hash through putPage via
content_hash on PageInput, so the stored hash matches the computed hash.
Previously the skip-if-unchanged check never fired because the hash
formulas differed.

MCP server now passes dry_run from tool params to OperationContext.

* chore: bump version and changelog (v0.3.0.0)

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

* fix: schema loader handles PL/pgSQL $$ blocks

Delete the semicolon-based SQL splitter in db.ts which broke on
PL/pgSQL trigger functions containing semicolons inside $$ delimiter
blocks. Use single conn.unsafe(schemaSql) call instead — the postgres
driver handles multi-statement SQL natively. schema.sql already uses
IF NOT EXISTS / CREATE OR REPLACE for idempotency.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat: E2E test infrastructure + realistic brain fixtures

Add test infrastructure for running E2E tests against real
Postgres+pgvector. Includes:
- test/e2e/helpers.ts: DB lifecycle, fixture import, timing, diagnostics
- 13 fixture files as a miniature realistic brain (people, companies,
  deals, meetings, concepts, projects, sources) following the
  compiled truth + timeline format from GBRAIN_RECOMMENDED_SCHEMA.md
- docker-compose.test.yml: local pgvector convenience (port 5433)
- .env.testing.example: template for test credentials
- package.json: add test:e2e script

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat: E2E test suites + CI workflow

Tier 1 (mechanical.test.ts): 14 test suites covering all operations
against real Postgres — page CRUD, search with quality scoring, links,
tags, timeline, versions, admin, chunks, resolution, ingest log, raw
data, files, idempotency stress, setup journey (full CLI flow), init
edge cases, schema idempotency, schema diff guard, performance baselines.

Tier 1 (mcp.test.ts): MCP protocol test — spawns server, sends JSON-RPC,
verifies tools/list matches operations count.

Tier 2 (skills.test.ts): OpenClaw skill tests — ingest, query, health.
Skips gracefully when dependencies missing.

CI (.github/workflows/e2e.yml): Tier 1 on every PR (pgvector service),
Tier 2 nightly/manual with API key secrets.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: E2E test fixes + traverseGraph jsonb cast

- Fix traverseGraph query: cast json_agg to jsonb_agg so SELECT DISTINCT works
- Fix put_page tests to use importFromContent with noEmbed (no OpenAI key in Tier 1)
- Fix get_health assertion (page_count not total_pages)
- Fix raw_data test to handle JSONB string/object return
- Simplify MCP test to verify tool generation directly
- Add timeouts to CLI subprocess tests
- Use port 5434 for docker-compose (5433 often in use)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* docs: update all project docs for E2E test suite

- CLAUDE.md: updated test count (9 unit + 3 E2E), added E2E test
  instructions, fixed skill count to 8
- CONTRIBUTING.md: updated project structure with test/e2e/, added E2E
  test instructions, rewrote "Adding a new command" to reflect
  contract-first architecture (add to operations.ts, done)
- README.md: fixed table count (10 not 9), added recommended schema doc
  to Docs section, added E2E instructions to Contributing section
- CHANGELOG.md: added E2E test suite, docker-compose, schema loader fix,
  and traverseGraph jsonb fix to v0.3.0 entry

 		ecebd5552a feat: GBrain v0.2.0 — incremental sync, file storage, install skill (#2) 
* refactor: extract importFile from import.ts + add tag reconciliation

Shared single-file import function used by both import and sync.
Adds tag reconciliation (removes stale tags on reimport), >1MB file
skip, and import->sync checkpoint continuity (writes git HEAD to
config table after import so sync picks up seamlessly).

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

* feat: add sync pure functions, updateSlug engine method, and sync tests

- buildSyncManifest: parses git diff --name-status -M output
- isSyncable: filters to .md pages, excludes hidden/ops/.raw/skip-list
- pathToSlug: converts file paths to page slugs with optional prefix
- updateSlug: renames page slug in-place (preserves page_id, chunks, embeddings)
- rewriteLinks: stub for v0.2 (FKs use page_id, already correct)
- 20 new tests, all passing (39 total across 3 files)

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

* feat: add gbrain sync command with CLI, MCP, and watch mode

18-step sync protocol: read config, git pull, ancestry validation,
git diff --name-status -M for net changes, isSyncable filter, process
deletes/renames/adds/modifies via importFile, batch optimization,
sync state checkpoint in Postgres config table. Watch mode with
polling and consecutive error counter. MCP sync_brain tool returns
structured SyncResult. Stale page deletion for un-syncable files.

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

* feat: add files table, gbrain files commands, and config show redaction

- files table: page_slug FK with ON DELETE SET NULL + ON UPDATE CASCADE,
  storage_path, storage_url, mime_type, content_hash for dedup
- gbrain files list/upload/sync/verify commands for Supabase Storage
- gbrain config show redacts postgresql:// passwords and secret keys
- CLI help updated with FILES section

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

* feat: add install skill for GBrain onboarding

6-phase install workflow: environment discovery, Supabase setup (magic
path via CLI OAuth or fallback 2-copy-paste), init + import, ongoing
sync cron, optional file migration with mandatory verification, and
agent teaching (AGENTS.md rules). Every error gets what + why + fix.

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

* docs: update project documentation for v0.2.0

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

* docs: add v0.2 features to README (sync, files, install skill)

README.md: added sync command to IMPORT/EXPORT section, added FILES
section with 4 commands, added files table to schema diagram, added
install skill to skills table, updated MCP tools count from 20 to 21
(sync_brain added).

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

* fix: OpenClaw DX improvements (skill count, upgrade docs, config show help)

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

* refactor: consolidate version to single source of truth

Create src/version.ts that reads from package.json via static import
(safe for bun compiled binaries). Update mcp/server.ts from hardcoded
'0.1.0' to use shared VERSION. Bump skills/manifest.json to 0.2.0.

* fix: upgrade detection order, npm→bun naming, clawhub false positives

Reorder detection: node_modules first, binary second, clawhub last.
Rename 'npm' install method to 'bun'. Use 'clawhub --version' instead
of 'which clawhub' to avoid false positives from dangling symlinks.
Add 120s timeout to execSync calls to prevent hanging. Add --help flag.

* feat: per-command --help, unknown command check before DB connection

Add COMMAND_HELP map covering all 28 commands. Check --help before
init/upgrade dispatch and before connectEngine() so help works without
a database. Use COMMAND_HELP keys as known-command set to catch unknown
commands before wasting a DB round-trip.

* docs: standardize npm references to bun, add Upgrade section to README

Fix init.ts: npx→bunx, npm→bun for supabase CLI guidance.
Fix README: npm install→bun add for standalone CLI install.
Add ## Upgrade section to README with all three install methods.
Update install skill Upgrading section to list bun, ClawHub, and binary.

* test: full coverage audit — CLI dispatch, upgrade detection, config, edge cases

New test files:
- test/cli.test.ts: COMMAND_HELP ↔ switch consistency, version from
  package.json, per-command --help, unknown command handling, global help
- test/upgrade.test.ts: detection order verification, npm→bun naming,
  clawhub --version (not which), timeout presence
- test/config.test.ts: redactUrl for postgresql URLs, edge cases

Extended existing tests:
- test/sync.test.ts: empty string pathToSlug, uppercase .MD rejection,
  deeply nested files, multiple renames, unknown status codes
- test/markdown.test.ts: multiple --- separators, missing frontmatter,
  no frontmatter at all, empty string, type inference from paths

Tests: 39 → 83 (+44 new). All pass.

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

* test: 100% coverage — import-file mock engine, files utils, chunker edge cases

New test files:
- test/import-file.test.ts (9 tests): mock BrainEngine to test importFile
  without DB — MAX_FILE_SIZE skip, content_hash dedup, tag reconciliation
  (remove stale + add new), compiled_truth/timeline chunking, noEmbed flag,
  sequential chunk_index
- test/files.test.ts (22 tests): getMimeType for all extensions + uppercase
  + unknown + no-extension, fileHash consistency + different content + empty,
  collectFiles pattern (skip .md, skip hidden dirs, recurse, sorted output)

Extended:
- test/chunkers/recursive.test.ts (+6 tests): single newline splits,
  word-only text, clause delimiters, lossless preservation, default options,
  mixed delimiter hierarchy

Tests: 83 → 118 (+35 new). All pass.

 		b22cbd349a feat: GBrain v0.1.0 — Postgres-native personal knowledge brain (#1) 
* chore: add CLAUDE.md with project context and gstack skill routing rules

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

* chore: initialize project with Bun + TypeScript

package.json with dependencies (postgres, pgvector, openai, anthropic,
MCP SDK, gray-matter). TypeScript config targeting ESNext with bundler
module resolution.

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

* feat: add foundation layer — engine interface, Postgres engine, schema

BrainEngine pluggable interface with full PostgresEngine: CRUD, search
(keyword + vector), links, tags, timeline, versions, stats, health,
ingest log, config. Trigger-based tsvector spanning pages +
timeline_entries. Markdown parser with frontmatter, compiled_truth /
timeline splitting, and round-trip serialization. 19 tests passing.

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

* feat: add 3-tier chunking and embedding service

Recursive delimiter-aware chunker (5-level hierarchy, 300-word chunks,
50-word overlap). Semantic chunker with Savitzky-Golay boundary detection
and recursive fallback. LLM-guided chunker via Claude Haiku with sliding
window topic detection. OpenAI embedding service with batch support,
exponential backoff, and rate limit handling.

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

* feat: add hybrid search with RRF fusion, expansion, and 4-layer dedup

Hybrid search merges vector (pgvector HNSW) + keyword (tsvector) via
Reciprocal Rank Fusion. Multi-query expansion via Claude Haiku generates
2 alternative phrasings. 4-layer dedup pipeline: by source, cosine
similarity, type diversity (60% cap), per-page cap.

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

* docs: add GBRAIN_V0 spec, pluggable engine architecture, SQLite engine plan

GBRAIN_V0.md: full product spec with architecture decisions, CLI commands,
schema, search architecture, chunking strategies, first-time experience,
and future plans. ENGINES.md: pluggable engine interface, capability matrix,
how to add new backends. SQLITE_ENGINE.md: complete SQLite implementation
plan with schema, FTS5 setup, vector search options, and contributor guide.

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

* feat: add CLI with all commands

Full CLI dispatcher with 25+ commands: init (Supabase wizard), get, put,
delete, list, search, query (hybrid RRF), import (bulk with progress bar),
export (round-trip), embed, stats, health, tag/untag/tags, link/unlink/
backlinks/graph, timeline/timeline-add, history/revert, config, upgrade,
serve, call. Smart slug resolution on reads. Version snapshots on updates.

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

* feat: add MCP stdio server with all brain tools

20 MCP tools mirroring CLI operations: get/put/delete/list pages,
search (keyword), query (hybrid RRF + expansion), tags, links with
graph traversal, timeline, stats, health, version history, and revert.
Auto-chunks and embeds on put_page. CLI and MCP share the same engine.

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

* feat: add 6 skill files and ClawHub manifest

Fat markdown skills for AI agents: ingest (meetings/docs/articles with
timeline merge), query (3-layer search + synthesis + citations), maintain
(health checks, stale detection, orphan audit), enrich (external API
enrichment), briefing (daily briefing compilation), migrate (universal
migration from Obsidian/Notion/Logseq/markdown/CSV/JSON/Roam).
ClawHub manifest for skill distribution.

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

* docs: add README, CONTRIBUTING, update CLAUDE.md test references

README with quickstart, commands, architecture, library usage, MCP setup,
and links to design docs. CONTRIBUTING with setup, project structure,
and guides for adding commands and engines. CLAUDE.md updated to reference
actual test files instead of planned-but-unwritten import test.

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

* fix: address adversarial review findings — 5 critical/high fixes

- revertToVersion: add page_id check to prevent cross-page data corruption
- traverseGraph: use UNION instead of UNION ALL for cycle safety
- embedAll: preserve all chunks when embedding stale subset only
- embedding: throw on retry exhaustion instead of returning zero vectors
- putPage: validate slugs to prevent path traversal on export

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

* chore: bump version and changelog (v0.1.0)

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

* docs: expand README with schema, install, search architecture, and motivation

Why it exists, how search works (with ASCII diagram), full database schema
with all 9 tables and index details, chunking strategies explained, storage
estimates, setup wizard walkthrough, knowledge model with example page,
library usage with more examples, expanded skills table.

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

* chore: add MIT license (Copyright 2026 Garry Tan)

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

* docs: add OpenClaw install flow as primary option in README

OpenClaw users just say "install gbrain" and the orchestrator handles
everything: package install, Supabase setup wizard, skill registration.
Shows the conversational interface for querying, ingesting, and briefings.
ClawHub and standalone CLI paths follow as alternatives.

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

* docs: add prerequisites and explicit OpenClaw install instructions

Prerequisites table listing Supabase, OpenAI, and Anthropic dependencies
with links. Environment variable setup. Explicit step-by-step prompt for
OpenClaw users showing exactly what to tell the orchestrator. Note that
search degrades gracefully without API keys (keyword-only without OpenAI,
no expansion without Anthropic).

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

* docs: scrub named references, add PG essay demo section to README

Replace all Pedro/Brex/Jensen Huang/River AI examples with Paul Graham
essay examples using the kindling corpus. Add "Try it" section to README
showing the power of hybrid search on PG essays in 90 seconds. Update
test fixtures to use concept pages instead of person pages.
