v0.3.0 - Cognitive OS agent practice

v0.3.0 — Cognitive OS agent practice

Feature release building on v0.2.1. The existing memory and graph tools remain
available; the Cognitive OS schema and MCP surfaces are additive.

Highlights

• Eight Cognitive OS tools, bringing the complete MCP surface to 35 tools.
• Immutable, hash-linked evidence events with scoped correlation, causation,
  and idempotency support.
• Candidate-policy creation, lookup, and evaluation without automatic
  promotion or authority expansion.
• Governing and contextual current-guidance lanes plus a non-mutating
  diagnostic surface.
• A strictly read-only cognitive_agent_bootstrap that resolves project scope,
  snapshots requested canonical records, and returns policy and guidance
  candidates without appending events or touching access counters.
• A portable agent-practice contract with generated Codex, Claude, Gemini, and
  vendor-neutral adapters, deterministic compliance grading, and an optional
  MiniMax review path.
• Updated cross-client setup documentation and a portable Windows launcher.

Safety boundaries

• Retrieval rank and governing eligibility do not establish authority.
• Candidate policies remain advisory and cannot broaden permissions.
• _global guidance stays excluded unless explicitly requested.
• Hook-driven candidate detection and hard enforcement remain disabled.

Verification

• 16 test files / 167 tests passed.
• npx tsc --noEmit passed.
• Generated agent-practice adapters passed freshness checks.
• Focused agent-practice tests passed.
• The frozen coverage harness reproduced deterministic baseline and treatment
  results.

Upgrade

Pull or download v0.3.0, run npm install, and restart the MCP server. Existing
memory databases are retained; the Cognitive OS tables are initialized
additively when the server starts.
