Physically move the pure-code subtrees out of .specify into the package, leaving compat symlinks at the old .specify/<dir> paths so every existing reference (internal CASAN_HARNESS_ROOT + external CI/docker/mjs) keeps resolving. Runtime state stays put. Moved (git mv): scripts/ tests/ security/ templates/ config/ governance/ memory/ .specify/<dir> -> packages/casan-harness/<dir> (+ .specify/<dir> symlink) Stays in .specify (state/governance/domain, handled later): logs/ agentops/ level5/ init-options.json traceability-map.json Python `.resolve()` self-location followed the compat symlink into packages and lost the app root; generate-casan-demo-context.py, generate-agentops-dashboard.py and dashboard-server.py now walk UP for the `.specify` state marker instead of a fixed parent depth (fixes "missing trace files" in run-casan4). Full gate: PASS=64 FAIL=0 SKIP=3 (CASAN_CI_STEP_TIMEOUT_SEC=1200 — track-a ~450s runs close to the 600s default and can tip over under load; this is timing variance, not a regression — it passed cleanly with headroom). Runtime log/audit artifacts kept unstaged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# CASAN Plan-16 SEC-16 (ARCH-01) — signed harness + policy bundle.
|
|
#
|
|
# Editing a gate or policy file (security-check.sh, prompt-filter.yaml,
|
|
# thresholds.yaml, *.pin, reviewers.registry) disables a control with no input
|
|
# trace. The signed bundle manifest binds the harness code + policy; the harness
|
|
# verifies its self-hash and refuses on drift. Proves:
|
|
# * intact bundle verifies (permissive + strict/signed),
|
|
# * a 1-byte edit to a gate script → verify FAIL (drift),
|
|
# * a new unmanifested policy file → verify FAIL,
|
|
# * a tampered manifest → verify FAIL (signature invalid),
|
|
# * casan-harness in prod REFUSES to run when the bundle has drifted.
|
|
#
|
|
# Deterministic; hermetic (temp bundle root + temp keys/manifest).
