CHANGELOG

Platform Evolution & Compliance Ledger

A transparent record of infrastructure upgrades, security hardening, and audit capabilities.

v1.2.0 — Historical Forensic Backfill & Ingestion Lanes

December 22, 2025

Infrastructure Deployment: Deployed the Dual-Lane Ingestion Architecture, enabling deterministic historical analysis and audit trail reconstruction for new workspaces.

  • NewHistorical Backfill Lane: Deterministic scanning of last 2 years of git history with SHA-256 fingerprinting for immediate ledger population.
  • NewRetroactive Audit Indexing: Forensic reconstruction of previously resolved incidents through graph traversal of historical resolution artifacts.
  • ImprovementNormalization Engine: Enhanced path sanitization schema for webpack:// prefixes in monorepo architectures to improve deterministic matching throughput.

v1.1.8 — Ingestion Integrity Controls

December 10, 2025

SECURITY Ingestion Integrity: Enforced strict symbolication validation on the Real-Time Lane. Payloads with minified frames lacking source map correlation are now rejected at the edge gate to prevent schema pollution.

v1.1.5 — Dependency Hardening

December 5, 2025

SECURITY Dependency Hardening: Upgraded downstream cryptographic libraries to mitigate CVE-2024-XXXX. Enforced stricter TLS requirements on webhook ingress for enhanced audit trail integrity.

v1.1.4 — The "Revert" Penalty

December 1, 2025

Forensic Verification: Refined deterministic scoring algorithms for the Validation Orchestrator to improve regression detection accuracy and audit trail completeness.

  • NewRevert Detection: If a validated PR is reverted within 24h, the solution signature is invalidated in the ledger to maintain integrity.
  • ImprovementRate Gate Calibration: Adjusted entropy threshold sensitivity to reduce false positives during low-traffic windows while maintaining deterministic accuracy.

v1.1.0 — Cross-Service Alerting

November 28, 2025

Graph Traversal Enhancement: Knowledge Graph now supports cross-service alert broadcasting with deterministic delivery guarantees.

  • NewPredictive Push Delivery: Deterministic alert routing across service boundaries with latency tracking in the audit ledger.
  • IntegrationSlack Webhook Integration: Added secure webhook delivery channel with integrity verification.

v1.0.0 — General Availability

October 15, 2025

Platform Launch: Déjà General Availability — the first deterministic incident resolution platform with forensic verification and audit trail capabilities.

  • FeatureDeterministic Matcher: SHA-256 based forensic linkage of Sentry stack traces to GitHub PR resolution artifacts.
  • FeatureCryptographic Rate Gates: Automated fix verification through deterministic entropy analysis with integrity checks.
  • IntegrationIngestion Pipeline: Initial Sentry & GitHub webhook integration with dual-lane processing architecture.
