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-02 (H-02) — no local key auto-generation in enforced mode.
|
|
#
|
|
# The tamper-evidence of the audit chain rests on the head signature. If the
|
|
# signer auto-generates a private key next to the data (as dev convenience does),
|
|
# then any actor who can write the log can also mint a key and re-sign a forged
|
|
# head. In enforced mode the signer must NOT auto-generate — the key is provisioned
|
|
# out-of-band (KMS/HSM). This proves:
|
|
# * permissive mode still auto-generates a local key (dev convenience),
|
|
# * enforced mode does NOT create a key when none is provisioned, and the
|
|
# resulting unsigned head then FAILS strict verification (fail-closed).
|
|
#
|
|
# Deterministic; hermetic (temp key dir + backup/restore of audit + gov dirs).
