…13) apm-action@v1 with default inputs runs 'apm install' which re-deploys managed primitives from upstream and OVERWRITES any tampered file in the PR. That silently disables content-integrity / drift detection. Switch to setup-only: true (apm CLI on PATH, no install). apm audit then runs against the PR's actual file state, so drift fires when expected. Caught while wiring D2 governance demo Beat 5 (DevExpGbb/zava-storefront#18, which initially passed CI green despite a clear tamper of secure-coding-base).

Demo artifact — D2 Governance, Beat 5 (drift detection)
Scenario: A developer edits a deployed managed instruction file —
.github/instructions/secure-coding-base.instructions.md(produced byzava-agent-config/plugins/secure-baseline) — to weaken the "no string-concatenation into SQL" rule. The lockfile (apm.lock.yaml) records the expected SHA256 of every deployed file.apm audit --cirecomputes hashes and fails on drift.Expected CI result: RED on
content-integrity+driftchecks.Local verification:
Aha for the room: the floor is signed, end-to-end. Hand-edit a managed file → CI catches it on the next PR. Restoration is one
