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>

#
|
|
# Proves:
|
|
# * a strictly improving progress series -> CONVERGING (exit 0),
|
|
# * N identical consecutive actions -> OSCILLATING (repeat),
|
|
# * A,B,A,B... alternation -> OSCILLATING (thrash),
|
|
# * flat progress over the window -> STALLED,
|
|
# * on_stall=escalate -> ESCALATE (exit 4); on_stall=halt -> HALT (exit 3),
|
|
# * a corrupt observation stream fails closed (HALT, not silent CONVERGING),
|
|
# * verdicts write a hash-linked audit record,
|
|
# * state is redirected -> repo .specify/state stays clean.
