security-gate.sh checked only `command -v node` before running
`npm test -w frontend`. In the CI security-gate job, node is in PATH
(from actions/setup-node) but root node_modules are NOT installed
(npm ci was removed to prevent OOM). This caused the frontend test to
fail with "Cannot find module vitest".
Fix: also require node_modules/.bin/vitest to exist. Without it the
step SKIPs gracefully — frontend tests are already covered by the
dedicated frontend-tests CI job which runs first.

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)
