[0.9.0a3] — in progress

Status: active alpha release prep — pre-stable, not for production
federation across organizational boundaries. Final release evidence, security
posture, and publication notes are completed through the v0.9.0a3 milestone
before tag.

Per-ecosystem version strings (per ADR-019):

• PyPI / Python: stigmem 0.9.0a3, stigmem-py 0.9.0a3, stigmem-node 0.9.0a3, and stigmem-openclaw 0.9.0a3 (PEP 440).
• npm / Node: @eidetic-labs/stigmem-ts@0.9.0-alpha.3 (semver).
• GHCR: ghcr.io/eidetic-labs/stigmem-node:0.9.0a3 and :0.9.0-alpha.3.
• Git tag, GitHub release, prose: v0.9.0a3 (shorthand).

Added

• Validated content-addressed fact IDs as a core alpha feature across the
  feature record, modular spec projection, compatibility matrix, and release
  evidence surfaces.
• Captured a3 release-readiness evidence for the core Python packages,
  TypeScript SDK package, OpenClaw adapter package, GHCR tag posture, and docs
  publication posture.

Changed

• Advanced the enforced release-version surfaces to the active v0.9.0a3
  alpha line so package, API metadata, conformance, plugin fallback, and
  release-documentation surfaces use consistent per-ecosystem spellings.
• Align roadmap, security, operator, SDK, and spec documentation around the current release horizon: v0.9.0a3 is the only active release target; beta, release-candidate, and GA lines remain future gates until explicitly opened.
• Prepared the OpenClaw adapter and ClawHub skill metadata for the a3 alpha
  artifact line while preserving the alpha/evaluation-only posture.

Security

• Reconciled a3 release notes and security posture with the standing
  publication policy: Critical and High findings use GHSA where applicable;
  Medium and Low dispositions remain in SECURITY.md unless a documented
  carve-out applies.
• Kept the dated security evidence registry as a proof ledger and SECURITY.md
  as the public disposition index, avoiding duplicate advisory tables in a3
  release notes.
