thanhnvandClaude Opus 4.8 664bd1f00c feat(plan-01): Phase 1 — relocate harness code to packages/casan-harness (symlink facade)
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.

# CASAN WP-S2 — quantitative H4 red-team metrics.
# Runs each labeled corpus sample through BOTH layers:
# tier1 = regex/normalization (security-check.sh, semantic OFF)
# tier2 = model classifier (model-router.sh --role classify)
# Computes precision/recall for each and proves the model layer adds recall
# over regex alone. Requires the Ollama tunnel; if down, reports BLOCKED (not pass).
#
# Gate: model recall >= MODEL_RECALL_MIN AND model recall > regex recall.
