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-25 (SC-07, offline) — build-artifact attestation (tested==deployed).
|
|
#
|
|
# A green CI gate proves the TESTED artifact is sound, but nothing binds it to what
|
|
# is DEPLOYED — a different artifact could ship. This produces a signed attestation
|
|
# over an artifact's content hash; verification recomputes the hash and checks the
|
|
# signature, so a swapped/modified artifact (deployed != tested) or a forged
|
|
# attestation is REFUSED (fail-closed). Offline form of SLSA-style provenance;
|
|
# real signed-commit enrollment + full provenance chain need CI/key infra.
|
|
#
|
|
# Usage:
|
|
# artifact-attest.sh attest <artifact> <priv-key> # -> <artifact>.att (+ .att.sig)
|
|
# artifact-attest.sh verify <artifact> <attestation> <pub> # tested==deployed check
|
|
# Exit: 0 ok · 2 mismatch/forged/tampered · 3 missing/unsigned/openssl · 64 usage.
