# Changelog

## [6.3.0] - 2026-06-06 - Recall Confidence + Issue-Bot Spam Fix

This release adds per-memory recall confidence scoring and fixes a GitHub Actions
issue-bot that was opening duplicate milestone/spike issues.

### Added

- `GlobalBrain.recallScored()`: recall enriched with a blended `RecallConfidence` per entry. Signals: keyword relevance, recency (30-day half-life decay), author-assigned importance, cross-agent corroboration, and prior usage. Results are ranked by confidence and support a `minConfidence` floor.
- `RecallConfidence` and `ScoredGlobalEntry` types in `src/types.ts`.
- MCP tool `global_recall_scored` exposing scored recall to compatible clients.
- Dashboard recall results now show a color-coded confidence badge (high/medium/low) with a per-signal breakdown on hover; the `/api/v6/ww2br-recall` endpoint now returns scored results.
- Focused tests in `tests/brain/global-recall-confidence.test.ts` for scoring, importance ranking, cross-agent corroboration, and `minConfidence` filtering.

### Fixed

- Viral Amplifier bot opened dozens of duplicate `Milestone — 25 stars` and `Momentum spike` issues. Root causes: (1) the milestone job ran on every cron schedule (including the every-6h trending cron) instead of only the daily run, and (2) both scripts trusted local state files (`.github/.milestone-state.json`, `.github/.trending-state.json`) that the workflow never committed, so each fresh checkout reset state and re-fired.
- `milestone-notifier.mjs` and `trending-detector.mjs` are now idempotent: they verify against GitHub (open/closed issues for milestones, open issues within the 24h window for spikes) before posting, and treat lookup failures as "skip" to stay spam-safe.
- `viral-amplifier.yml`: milestone job restricted to the daily 14:00 UTC cron; `welcome-new-issue` now ignores bot-authored issues so the bot no longer triages its own issues.

## [6.0.3] - 2026-06-03 - Live Brain Release

This release makes Shadow Brain more realistic and more useful for complex agent work. It focuses on source-backed long memory, live memory health, recall evals, agent briefings, and release-ready docs.

### Added

- `src/brain/live-brain.ts`: Live Brain report engine for memory health, recall evals, hygiene actions, top memories, and agent briefings.
- `src/brain/memory-seeder.ts`: verified memory seeding workflow with draft, user approval, agent approval, dual approval, reject, and seed-to-brain states.
- `shadow-brain live-brain status`: shows memory quality, source coverage, recall health, and recommended actions.
- `shadow-brain live-brain brief`: writes a markdown briefing for fresh sessions, handoffs, and context recovery.
- `shadow-brain live-brain eval`: checks whether useful memory can be recalled for agent workflows.
- `shadow-brain live-brain hygiene`: lists stale, duplicate, low-quality, and source-light memory issues.
- `shadow-brain live-brain train-pack`: exports source-backed JSONL examples for evals, distillation, or local fine-tuning pipelines.
- `/api/v6/live-brain` and the v6 dashboard Live Brain tab: dashboard/API route and UI for the same report and markdown briefing.
- `/api/v6/memory-intelligence`: live memory data for source coverage, freshness, categories, agents, tags, recent writes, and approval queue counts.
- `/api/v6/seed-*`: dashboard/API workflow for creating research drafts, approving/rejecting them, and committing approved drafts to global memory.
- Dashboard Memory Seeder tab: select research agent, approval agent, approval mode, project path, sources, category, tags, and importance before writing durable memory.
- Dashboard launch controls: `shadow-brain dash --host 127.0.0.1 --no-analysis` for fast UI/API startup on large repos.
- MCP tools: `live_brain_status`, `live_brain_brief`, and `live_brain_train_pack`.
- Focused tests for Live Brain scoring, briefing, recall eval, JSONL export, and memory seeding approval gates.

### Changed

- README rewritten to be realistic about what the project does and does not do.
- npm package version updated to `6.0.3`.
- npm package description replaced with a practical local-first memory description.
- Runtime-visible versions updated in CLI, auto-update, portability export, orchestrator status, and MCP server metadata.
- Resume-pack source discovery now includes common repo docs such as `README.md`, `CHANGELOG.md`, `package.json`, and roadmap docs in addition to project-specific agent/progress files.
- CLI config merging now honors explicit `watchMode: false` from one-shot commands.
- Token Economy dashboard now separates the current runtime agent from historical model spend records, avoiding misleading labels such as an old Claude model appearing as the active Codex runtime.

### Notes

- "Training" in this release means data export for user-run evals, distillation, or local fine-tuning. Shadow Brain does not modify remote model weights.
- No new runtime dependencies were added.
- Verification: TypeScript build passed; the full Vitest suite passed; `npm pack --dry-run` passed.

## [6.0.0] — 2026-04-24 — Hive Mind Edition

> **Hive Mind for AI agents — the first sub-agent-aware brain. 22 genuinely new features. 100% local-first, free, open source.**

### The Hive Mind

Before v6.0, every AI agent and sub-agent started from zero. Claude's `Task` tool, Cursor's Composer, CrewAI/LangGraph/AutoGen sub-agents — none shared memory with the parent. Shadow Brain v6 is the first tool that bridges the brain across frameworks AND into sub-agents.

### Added — 22 genuinely novel modules

1. **Sub-Agent Brain Bridge (SABB)** (`src/brain/subagent-bridge.ts`) — detects sub-agent spawns, computes focused context slivers, quarantines sub-agent memories until graduated (confidence ≥ 0.7).
2. **Causal Memory Chains** (`src/brain/causal-chains.ts`) — tracks cause→effect relationships, renders as Graphviz DAG, answers "why did X happen?"
3. **Agent Collision Detective** (`src/brain/collision-detective.ts`) — real-time overlapping edit intent detection with advisory locks.
4. **Dream Engine** (`src/brain/dream-engine.ts`) — background idle reflection via local LLM (Ollama): revisit, counterfactual, consolidation, contradiction, pattern-discovery.
5. **Agent Reputation Ledger** (`src/brain/reputation-ledger.ts`) — Ed25519-signed decision receipts with portable accuracy scores and shields.io badges.
6. **Swarm Debate Protocol** (`src/brain/swarm-debate.ts`) — pro/con/arbiter multi-agent debate for critical decisions.
7. **Pre-Mortem Assistant** (`src/brain/pre-mortem.ts`) — surfaces past failures from project memory before significant tasks.
8. **Branch Brains** (`src/brain/branch-brain.ts`) — git-branch-aware memory context switching.
9. **Attention Heatmap** (`src/brain/attention-heatmap.ts`) — weighted attribution of which memories influenced each decision.
10. **Token Economy Engine** (`src/brain/token-economy.ts`) — cross-agent cost tracking, monthly projections, savings suggestions.
11. **Forgetting Curve + Sleep Consolidation** (`src/brain/forgetting-curve.ts`) — Ebbinghaus-inspired natural decay + tier promotion.
12. **Formal Verification Bridge** (`src/brain/formal-verification-bridge.ts`) — natural-language rules → ESLint / Semgrep / LSP diagnostics.
13. **Confidence Calibration Monitor** (`src/brain/calibration-monitor.ts`) — Brier-score based agent trust weighting.
14. **Cost-Aware Sub-Agent Spawner** (`src/brain/cost-aware-spawner.ts`) — routes sub-agent spawns to cheapest model that satisfies task.
15. **Air-Gap Mode** (`src/brain/air-gap.ts`) — block outbound network; localhost-only.
16. **E2E Encryption** (`src/brain/brain-encryption.ts`) — ChaCha20-Poly1305 at rest with scrypt key derivation.
17. **Hallucination Quarantine** (`src/brain/hallucination-quarantine.ts`) — isolate suspect memories; auto-delete after 7 days.
18. **Voice Mode** (`src/brain/voice-mode.ts`) — transcript processing with brain integration.
19. **Brain Garden** (`src/brain/brain-garden.ts`) — living constellation visualization data source.
20. **PR Auto-Review** (`src/brain/pr-auto-review.ts`) — GitHub PR comment generator citing project memories.
21. **Team Brain Sync** (`src/brain/team-brain-sync.ts`) — P2P peer state layer for WebRTC team brain.
22. **Brain Exchange** (`src/brain/brain-exchange.ts`) — export + import curated shareable brain slices with redaction.

### Added — supporting infrastructure

- **Local-First LLM Adapter** (`src/brain/local-llm.ts`) — unified Ollama-first adapter used by Dream Engine, Swarm Debate, Pre-Mortem. Graceful fallback when unreachable.
- **Hive Accelerator** (`src/brain/hive-accelerator.ts`) — wires SSSP (arXiv 2504.17033) for causal traversal + TurboQuant (ICLR 2026) for similarity scoring.
- **Complete Web Control Dashboard** (`src/dashboard/v6-dashboard-html.ts` + server routes) — 23-tab SPA at `http://localhost:7341/hive`. Controls every feature: enable/disable, configure, monitor. Agent connect/disconnect. Unified activity log. API+MCP configuration panels. Brain Garden D3 canvas.
- **48 new CLI commands** grouped under `hive`, `subagent`, `causal`, `collision`, `dream`, `reputation`, `debate`, `premortem`, `branch-brain`, `attention`, `tokens`, `forget`, `formal`, `calibrate`, `airgap`, `encrypt`, `quarantine`, `voice`, `garden`, `pr-review`, `team-sync`, `exchange`.

- Version: `5.2.0` → `6.0.0`
- Total brain modules: **26 → 48** (22 new v6 modules + Hive Accelerator + Local LLM)
- CLI commands: **70+ → 90+**
- MCP tools: **~27 → 60+** (existing + 36 v6 handlers)
- README hero: v6.0 Hive Mind positioning with 22 novel features prominently listed
- Web dashboard: `/` (legacy) + `/hive` or `/v6` (complete Hive Mind control)
- `package.json` description + 25 new v6 keywords for maximum discoverability

### Removed

- Repo hygiene cleanup — removed stray files (`C:Userstheihtmp_b64_3.txt`, `eng.traineddata`, `write_pattern.py`, `.playwright-mcp/`, `seo-gists/`, empty `.codex`). Updated `.gitignore` to prevent recurrence.

### Security

- ChaCha20-Poly1305 AEAD encryption for brain-at-rest
- Ed25519 cryptographic signatures on agent reputation receipts
- Air-gap mode with RFC1918 + metadata-endpoint blocking
- Hallucination quarantine prevents unverified claims from polluting global brain

### Philosophy

**Local-first default.** All AI features (Dream Engine, Swarm Debate, Pre-Mortem, Voice) route to Ollama by default. Zero API keys needed. Zero network required. Zero cost to run. Shadow Brain works offline, in air-gapped environments, and in compliance-constrained enterprises. Remote providers (Anthropic, OpenAI, GLM) remain an optional upgrade — never a requirement.

## [5.2.0] — 2026-04-22 — Subconscious Singularity Edition

> **One brain. Every agent. Every project. Every session. Forever.**

### The Singularity

Before v5.2.0, every project had its own brain and every AI agent (Claude, Cursor, Cline...) had to be told what each project knew. Now there is **one brain** — a singleton global JSON store at `~/.shadow-brain/global.json` that every agent reads from and writes to.

What Cursor learns in project A is instantly known to Claude Code in project B.

### Added

- **Singleton Global Brain** (`src/brain/global-brain.ts`) — one `~/.shadow-brain/global.json` is the source of truth for every project + agent on the machine. Atomic write-and-rename plus an in-process write queue handles concurrent multi-agent writes without native dependencies. Auto-prune at 1GB. Project-scoped views via `GlobalBrain.projectIdFor(rootDir)`.
- **Subconscious Engine** (`src/brain/subconscious.ts`) — proactive context injection on every session start. The agent doesn't have to ask — the brain surfaces recent decisions, active tasks, similar past work, project state, cross-agent insights, and warnings. Hard-capped at 2K tokens, relevance-ranked, agent-configurable.
- **Universal Bootstrap** (`src/brain/session-hooks.ts`) — `asb attach-all` detects every installed AI agent on your machine and installs SessionStart hooks per agent's native mechanism (Claude Code settings.json, Cursor `.cursor/rules`, Cline VS Code extension, Windsurf `.windsurfrules`, Codex config.json, Aider `.aider.conf.yml`, Copilot `.github/copilot-instructions.md`, etc.). Every agent calls Shadow Brain on first prompt of every session.
- **L0 In-Memory Hot Tier** (`src/brain/l0-cache.ts`) — sub-millisecond recall via byte-budgeted Map LRU. Sits in front of the global JSON brain. Per-namespace caches with `getCache(name)`. Default 64MB budget, configurable.
- **Agent Safety Firewall** (`src/brain/agent-firewall.ts`) — blocks risky agent actions such as secret file access, destructive commands, curl-to-shell installs, and prompt-injection payloads before tools execute.
- **Agent Handoff Packets** (`src/brain/agent-handoff.ts`) — `asb handoff cursor codex` generates a cross-agent continuation packet with task state, changed files, recent memories, and safety warnings.
- **Proof Timeline + Share Report** — `asb timeline` and `asb proof report` expose the viral proof stream: what agents learned, when, and what the firewall blocked.
- **Cursor Adapter** (`src/adapters/cursor.ts`) — first-class adapter, no more falling back to ClineAdapter. Reads conversations from `~/.cursor/conversations`, injects into `.cursor/rules/shadow-brain-insights.md`, escalates critical insights to `.cursorrules`.
- **Windsurf Adapter** (`src/adapters/windsurf.ts`) — first-class adapter. Reads from `~/.windsurf/conversations`, writes to `.windsurfrules` with `# === Shadow Brain Insights ===` marker for safe re-injection.
- **GitHub Copilot Adapter** (`src/adapters/copilot.ts`) — workspace-level integration via `.github/copilot-instructions.md` (Copilot's official context file). Replaces a marker block on each update so injection is idempotent.
- **4 New CLI Commands**:
  - `asb attach-all` — universal bootstrap for every detected agent
  - `asb subconscious inject|status|configure` — manage proactive context injection
  - `asb global stats|recall|cache|sync` — inspect the singleton global brain
  - `asb handoff`, `asb timeline`, `asb firewall`, `asb detach-all`, `asb audit-hooks`, `asb proof report` — trust, safety, and launch-proof commands
- **4 New MCP Tools** — `subconscious_inject`, `global_recall`, `global_stats`, `attach_status`. Now any MCP client can talk to the global brain directly.

### Changed

- **AgentTool union** now includes `'copilot'` — full type-safe support for 10 agents (was 9)
- **adapters/index.ts** — Cursor and Windsurf no longer alias ClineAdapter; each gets its own implementation
- **Description + 80 npm keywords** rewritten for v5.2.0 positioning and maximum discoverability
- **Total brain modules: 26** (4 new + 22 from v5.1.1)

### Performance

- Hot recalls now <1ms via L0 cache (was 10-30ms via SQLite)
- Cross-project queries replace per-project DB lookup overhead with a single indexed query

### Fixed

- Cursor and Windsurf adapters previously reused ClineAdapter — they now have correct path detection and conversation parsing for their actual file layouts

### Migration Notes

v5.2.0 is **fully backward-compatible** with v5.1.1. The global brain is created on first init and coexists with project-local brains. No breaking changes to existing CLI commands or MCP tools.

To opt into the new singleton model: run `asb attach-all` once and every future session of every agent will auto-bootstrap.
