Add a shared log taxonomy (error<warn<info<debug<trace, default info) wired
through all three layers, plus a machine-readable per-step run log.
- scripts/casan-log.mjs + .specify/scripts/bash/casan-log.sh: shared logger
([LEVEL] ts [component] msg), stderr-only so stdout contracts and exit codes
are byte-identical. Node side includes trace-level redaction (secret/PII).
- run-casan-pipeline.mjs: per-STEP info line, loop-activation warnings
(BACK-TO-PLAN, FAIL->STEP6), debug harness rc + trace_id, trace payload
excerpt, end-of-run 13-STEP summary table, and one JSONL line/step in
.specify/logs/pipeline-run.jsonl. New --dry-run stubs all agents but keeps
the real wrapper in the loop (deterministic, offline, full 13 STEP + loops).
- casan-step.mjs: debug logs for judge verdict, checkpoint, rollback; logger
import degrades to noop when the file is copied standalone (T1 test).
- casan-harness.sh: debug-log each phase H4-in -> H5 -> [H2-gate] -> H6-exec
-> H4-out with its rc; optional CASAN_PHASE_REPORT JSON for the Boss.
Default level (info) keeps output close to before; behavior opt-in via env.

T1 (H7): casan-step.mjs now calls rollback-manager.sh checkpoint before
overwriting plan.md at attempt-2, writes tx-id to plan.checkpoint.txid
sidecar, and executes rollback on REJECTED verdict. rollback-transactions.jsonl
records a real cp restore command. Adversarial test: checkpoint exists,
real cp command recorded, plan hash matches pre-overwrite content.
T4 (H6): casan-harness.sh exports CASAN_STEP_NAME=$ACTION_NAME before
agent-metrics.sh so nested model calls (model-call.py) and the provider-
cost-lookup.py query share the same step label. metrics.jsonl now writes
cost_source=provider_telemetry instead of word_count_estimate when a real
Ollama call is made within the same step. Adversarial test: verified with
CASAN_STEP_NAME=t4-telemetry-test end-to-end.
adversarial-harness-tests.sh: 40 → 44 PASS / 0 FAIL (+3 T1, +1 T4)
security-gate.sh: PASS=10 FAIL=0 SKIP=0 (verified, local ornith:9b)
