baf3517868 feat: v0.9.0 -- smart file storage, publish, production-grade skills (#62) 
* feat: battle-tested skill patterns from production deployment

Backport production-learned brain-operations patterns:
- Iron Law of Back-Linking (mandatory bidirectional linking)
- Brain filing rules (file by primary subject, not format)
- Enrichment protocol (7-step pipeline, 3-tier system, person/company templates)
- Media ingest workflows (articles, videos, podcasts, PDFs, screenshots)
- Citation requirements (mandatory [Source: ...] on every fact)
- Test Before Bulk operating principle
- Voice recipe: unicode crash fix, PII scrub, identity-first prompt, DIY STT+LLM+TTS
- X-to-Brain recipe: image OCR, Filtered Stream, tweet rating rubric, cron stagger

* chore: bump version and changelog (v0.8.1)

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

* docs: add _brain-filing-rules.md to CLAUDE.md key files

* feat: smart file upload with TUS resumable and .redirect.yaml pointers

- Supabase Storage auto-selects upload method by file size:
  < 100 MB standard POST, >= 100 MB TUS resumable (6 MB chunks + retry)
- Signed URL generation for private bucket access (1-hour expiry)
- New `upload-raw` command with size routing: small text stays in git,
  large/media files go to cloud with .redirect.yaml pointer
- New `signed-url` command for generating access links
- File resolver supports both .redirect.yaml (v0.9+) and .redirect (legacy)
- Redirect format upgraded: 10 fields with full metadata
- All migration commands (mirror, redirect, restore, clean) handle both formats

* feat: skills reference actual gbrain file commands

- Filing rules document upload-raw, signed-url, and .redirect.yaml format
- Ingest skill uses gbrain files upload-raw for raw source preservation
- Maintain skill adds file storage health checks
- Setup skill adds storage configuration phase with migration guidance
- Voice recipe uses upload-raw for call audio storage
- Migration v0.9.0 with complete storage setup instructions

* chore: bump version and changelog (v0.9.0)

* feat: gbrain publish -- shareable HTML with password protection

First code+skill pair: deterministic code does the work (strip private data,
encrypt with AES-256-GCM, generate self-contained HTML), the skill tells the
agent when and how to use it. 34 new tests.

See: https://x.com/garrytan/status/2042925773300908103

* feat: backlinks check/fix, page lint, and report commands

Three new deterministic tools (zero LLM calls):

- gbrain backlinks check/fix -- scans brain for entity mentions without
  back-links, creates them. Enforces the Iron Law from the skills.
- gbrain lint [--fix] -- catches LLM preambles, code fence wrapping,
  placeholder dates, missing frontmatter, broken citations, empty sections.
  --fix auto-strips fixable artifacts.
- gbrain report --type <name> -- saves timestamped reports to
  brain/reports/{type}/YYYY-MM-DD-HHMM.md for audit trails.

33 new tests (409 total, 0 fail).

* feat: v0.9.0 migration tells agents to swap scripts for built-in commands

Migration file now:
- Lists all 5 new deterministic commands with usage examples
- Includes a script-to-command replacement table (old -> new)
- Tells the agent to find custom script references in AGENTS.md,
  skills, and cron jobs and replace with gbrain commands
- Adds recommended cron jobs for daily backlink fix + weekly lint
- References the Thin Harness, Fat Skills thread

* fix: CLI routing bugs found during DX review

- Fixed subArgs reference error in handleCliOnly (used wrong variable name)
- Renamed gbrain backlinks check/fix to gbrain check-backlinks to avoid
  conflict with existing backlinks operation (per-page incoming links)
- Added TOOLS section to --help output showing publish, check-backlinks,
  lint, report
- Added upload-raw and signed-url to FILES section in --help
- Updated all docs/migration references to use check-backlinks

* fix: security hardening from adversarial review

- XSS: sanitize marked.parse() output (strip script/iframe/on* attrs)
- Path traversal: validate report --type against [a-z0-9-] pattern
- TUS: HEAD request before retry to get server's actual offset (TUS spec)
- Pointer: upload-raw now includes pointer content in JSON output
- Symlinks: use lstatSync in all walkers to prevent directory escape

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.

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

* 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.

* 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.

* 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

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.
