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>

# Shared tamper-evident appender for the central tool-call audit log
|
|
# (.specify/logs/audit/tool-calls.jsonl).
|
|
#
|
|
# Every record is chained: record_hash = SHA-256(previous_record_hash | core),
|
|
# where core is the canonical (sorted-key) JSON of the record minus record_hash.
|
|
# After each append the chain head is signed with the audit RSA key, so a
|
|
# re-forged chain (recomputed hashes) cannot produce a valid head signature
|
|
# without the private key. Used by both agent-metrics.sh and tool-registry-gate.sh
|
|
# so the combined audit is tamper-evident regardless of which writer appended.
|
|
#
|
|
# Production note: the private key must live off-repo (KMS/HSM); it is local
|
|
# here only for self-contained demonstration.
