Record Immutable Engineering Episode
Stores an ADR, bug root cause, invariant, migration, incident, or session note linked to files and entity IDs.
Protocol & Audit Catalog
7 MCP Tools, 4 Conflict Classes & Resources
Upsert Bi-Temporal Fact
Writes (subject_id, predicate, object) with automatic supersession when singular=True.
Compile Token-Budgeted Context
Ranks active facts and episodes using Okapi BM25 + 2-hop spreading activation within max_tokens.
Inspect Entity Ego-Graph
Retrieves active and optional historical edges around any service, file, or component ID.
Point-in-Time Snapshot (as_of)
Reconstructs the exact valid knowledge graph at any past ISO-8601 UTC timestamp.
Verify SHA-256 Merkle Chain
Recomputes cryptographic hashes across every stored fact and episode to verify tamper-free persistence.
Audit & Auto-Resolve Conflicts
Scans active facts for polarity, antonym, alias, or singular drift conflicts and optionally supersedes older claims.
Negation Polarity Conflict
Flags pairs like does_not_use_session_cookie vs uses_session_cookie on the same subject.
Opposing Antonym Object Conflict
Detects opposing state pairs such as stateful vs stateless, encrypted vs plaintext, or enabled vs disabled.
Canonical Predicate Alias Collision
Normalizes surface variants (e.g., requires_isolation vs isolation_level) that assert conflicting objects.
Unsuperseded Singular Value Drift
Catches concurrent active facts with divergent values written with singular=False.
Graph Counts & Schema Summary
Live entity, episode, active fact, and superseded fact counts.
Cryptographic Integrity Report
JSON SHA-256 verification status and Merkle root digest.
Recent Engineering Episodes
Latest ADRs, invariants, and root-cause records persisted to the graph.
Component Architecture Briefing
Compiles a token-budgeted briefing for a target service or module ID.
Bug Investigation Context
Retrieves invariants, historical root causes, and dependencies for a symptom.
