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 Track C-MVP — Supply-chain gate for generated dependencies (C2, V18).
|
|
#
|
|
# An agent that writes code can also add a dependency. This gate diffs a
|
|
# dependency manifest against a baseline and decides:
|
|
# BLOCK malicious/denylisted package, typosquat of a known package,
|
|
# or a dangerous lifecycle script (postinstall/preinstall/install) -> exit 2
|
|
# REQUIRE_APPROVAL a genuinely new dependency was added -> exit 3
|
|
# (ALLOW+audit when CASAN_ACTION_APPROVER is set)
|
|
# ALLOW no new dependencies -> exit 0
|
|
#
|
|
# Supports: package.json, requirements.txt, pom.xml, build.gradle(.kts).
|
|
# When npm audit / pip-audit / osv-scanner are installed they are recorded as
|
|
# available; otherwise the local denylist (malicious-packages.txt) is authoritative.
|
|
# The diff/scan logic lives in supply-chain-scan.py (deterministic, no network).
|
|
#
|
|
# Usage: supply-chain-gate.sh <manifest> [baseline-manifest] [report.json]
|
|
# If baseline is omitted, the manifest's committed git version is used.
