OMEGA BRAIN MCP + VERITAS BUILD GATES

Standalone Model Context Protocol Server with Built-In Intelligence + Deterministic Build Pipeline

Two files. One dependency. Full sovereign cognition + 10-gate build verification.

A self-contained MCP server that gives AI agents verifiable provenance, cross-session memory, a cryptographic audit trail, and a 10-gate deterministic build evaluation pipeline. No external server required.

SYSTEM INVARIANT: VERITAS Build does not determine whether code is 'good.' VERITAS Build determines whether code survives disciplined attempts to break it under explicitly declared primitives, constraints, test regimes, boundaries, cost models, evidence, and policy.

Architecture

Layer	Component	Role
Brain Core	Vault (SQLite)	Persistent session/entry storage with FTS5 search
Brain Core	SEAL Ledger	Append-only SHA3-256 hash chain for tamper-proof audit
Brain Core	RAG Provenance	Semantic embedding store with 3-tier engine (ST/fastembed/TF-IDF)
Brain Core	Cortex	Tri-Node approval gate with steer/block modes
Brain Core	Handoff	SHA-256 sealed cross-session memory transfer
Build Gates	10-Gate Pipeline	INTAKE→TYPE→DEPENDENCY→EVIDENCE→MATH→COST→INCENTIVE→SECURITY→ADVERSARY→TRACE/SEAL
Build Gates	Evidence Engine	Quality(e) formula, MIS_GREEDY, Agreement computation
Build Gates	CLAEG	Constraint-locked state machine with 3 terminal states
Build Gates	NAFE Scanner	Narrative failure signature detection

Verdict System

Verdict	Precedence	Meaning
`PASS`	0 (lowest)	All gates satisfied. Artifact is deployable under declared regime.
`MODEL_BOUND`	1	Gates pass but resource/coverage/confidence near redline. Deploy with monitoring.
`INCONCLUSIVE`	2	Insufficient evidence or timeout. Cannot affirm or deny. Block deploy.
`VIOLATION`	3 (highest)	Constraint failure, security vulnerability, or test failure. Block deploy.

Quick Start

Requirements

Python 3.11+
pip install mcp

Optional (better embeddings)

pip install fastembed              # ONNX embeddings, ~30MB
pip install sentence-transformers numpy  # Best quality, larger

Configure in Claude Desktop / Antigravity

CLAEG State Machine

INIT → { STABLE_CONTINUATION | ISOLATED_CONTAINMENT | TERMINAL_SHUTDOWN }
STABLE_CONTINUATION → { STABLE_CONTINUATION | ISOLATED_CONTAINMENT | TERMINAL_SHUTDOWN }
ISOLATED_CONTAINMENT → { STABLE_CONTINUATION | TERMINAL_SHUTDOWN }
TERMINAL_SHUTDOWN → {} (absorbing)

Invariant: Absence of an allowed transition is treated as prohibition.
