Summary of recent releases. Detailed change log available on request.

v1.0.52026-05-24

Defense-in-depth hardening release.

v1.0.4 shipped the capability. v1.0.5 hardens the perimeter around it, closing issues from an internal audit of the runtime and build pipeline. 815 tests pass on the release branch.

  • SSRF protection on the hosted-model adapter (rejects userinfo, IDN homoglyphs, private/loopback IPs).
  • Decompression-bomb defense on profile loading: large members stream to disk with inline hashing instead of into RAM.
  • Tar-smuggle defense: explicit member-type allow-list rejects sparse, hardlink, and LONGNAME entries.
  • CSV-injection defense on exported reports.
  • Input-size caps on the local model backend (8 KiB / 16 messages).
  • Numerical safety guards on the ML classifier (no more NaN cascades routing benign traffic to high-severity buckets).
  • Tighter regex bounds across the detection pipeline (preventing pathological-input compute blowup).
  • Six additional quality fixes around training reproducibility and report sanitization.
v1.0.42026-05-12

AI Deception capability ships.

The first release of the AI Deception product line. Two-layer detection in front of a fine-tuned decoy model, signed and verifiable profile bundles, per-tenant tuning, and a full adversarial test-suite release gate. Internal red-team validation measured 66 of 67 attack turns captured, with zero false positives on benign traffic.

  • AI Deception product line shipped: two-layer detection (rule-based + ML) sitting in front of a fine-tuned decoy model.
  • 98.5% threat capture on the internal adversarial test suite (66 of 67 attack turns).
  • Zero false positives on benign traffic.
  • 116 tracked credentials issued per 87-turn campaign.
  • Per-tenant detection rule overlays: additive only; baseline preserved; audit-logged.
  • Reproducible profile bundles: bit-identical rebuilds verified across runs.
  • Cryptographic signing of every profile bundle.
  • OpenAI-compatible HTTP endpoint for transparent in-line deployment.
