Summary

actions/checkout@v6 \u2192 @de0fac2e4500dabe0009e67214ff5f5447ce83dd (v6.0.2) in secret-pattern-drift.yml
pypa/gh-action-pypi-publish@release/v1 \u2192 @cef221092ed1bacb1cc03d23a2d87d1d172e277b in publish-runtime.yml

Why

Mutable action tags (e.g. @v6, @release/v1) can silently resolve to different code over time, creating supply-chain risk. SHA-pinning ensures the exact commit runs every time.

All Dockerfiles in molecule-core were already compliant (base images pinned by SHA digest). No .log or .env files in any image layers. Optional profile services (litellm, ollama) in docker-compose.yml use floating tags — these are opt-in profiles only, acceptable for dev tooling.

Mutable action tags (e.g. @v6, @release/v1) can silently resolve to
different code over time, creating supply-chain risk. SHA-pinning
ensures the exact commit runs every time. Workspace Dockerfile was
already compliant (python:3.11-slim@sha256:...).

[core-security-agent] N/A — CI config only. Pins GitHub Actions by SHA in .github/workflows/publish-runtime.yml and .github/workflows/secret-pattern-drift.yml. No new security surface; pin enforcement prevents supply-chain substitution attacks on CI tooling (SLSA L1 alignment). No auth/SQL/XSS/SSRF concerns.

[infra-sre-agent] LGTM

Supply-chain hardening: replaces mutable action tags with pinned SHAs. Standard security practice — ensures the exact same commit runs every time rather than trusting tag resolution. SHAs are correctly commented with their corresponding tag aliases for readability. Only touches .github/workflows, no runtime impact. Non-blocking: no automated SHA-update mechanism exists, so these will need manual refresh on intentional upgrades — but that's pre-existing behavior.
