// PROBLEM
▸AI agents suffer from context drift: they accumulate facts but cannot detect when new information directly contradicts stored beliefs, causing silent reasoning failures.
▸No open solution provided deterministic, ML-free memory with anti-contradiction enforcement, inheritance-weighted novelty tracking, and per-tenant isolation.
// SYSTEM_DESIGN
▸Antisymmetric Operator: cosine similarity detects opposing memory vectors (score < -0.5) and deterministically merges or cancels contradictions
▸Inheritance Graph: each node computes weighted parent fractions (sum=1) + residual novelty score via pure cosine arithmetic, no ML
▸10-Signal Re-ranker: char, word, phrase, entity, graph, temporal, concept, evidence, opposition penalty, redundancy penalty
▸FIG View: live Fractal Inheritance Graph canvas with node neighborhood, timeline overlays, and memory signal cards
▸Multi-tenant write/search APIs with provenance tracking from ingested source to retrieved memory
▸API key lifecycle: create / list / rotate / revoke with scoped authorization and full audit timeline
// SECURITY_MODELCRITICAL
▸Key expiry and revocation: effect immediate across all tenants at middleware level
▸Scope-based authorization with 403 on missing scopes, enforced before any storage access
▸Per-tenant data isolation at the PostgreSQL storage layer
▸Idempotent write path with safe retry behavior and exponential backoff
▸Fully deterministic operations: zero ML randomness, every output is auditable and reproducible
// VALIDATION
▸720 tests passing across backend, acceptance, and e2e suites. Production gate is green.
▸40+ engineering phases shipped: platform build, retrieval engine, auth/API keys, self-evolution, runtime realization
▸MyPy Strict + Bandit security scan + Ruff across all 167 Python modules: zero violations
▸Docker-composed microservice stack: API:8000 · Frontend:8010 · PostgreSQL:8020 · Redis:8030 · Qdrant:8040
