Trace a promise all the way to a customer.
Intent, exact build and operation.
Test both who gets access and who does not.
The customer agreement is the anchor.

Full written post / accessibility read
A PM's customer decision can be narrowed when passed to an agent team. In a fictional migration, one tenant gets temporary access; all others need a paid entitlement. If the task becomes 'make enterprise tenants eligible,' the implementation and tests may pass while the promise changes.
Intent records the source, tenant, expiry and owner. Build evidence ties protected allowed-and-denied tests to the commit digest. Operation reads the bounded customer cohort after deployment. Each rail can fail or be unverified independently; a green build cannot replace a missing source decision.
Run the migration tenant through the actual UI and API, then a non-entitled tenant through the same path. After a bounded canary, read back the user-facing result and rollback signal. If the migration cohort was not exposed, mark operational evidence inconclusive rather than celebrating a quiet dashboard.
Require every meaningful release to name the promise, exact artifact, independent evidence and post-release observation. Do this because an agent team can produce more finished-looking software while the business loses the thread of what it actually agreed to deliver.

Four-beat scene transcript
1. Trace a promise all the way to a customer.
A PM's customer decision can be narrowed when passed to an agent team. In a fictional migration, one tenant gets temporary access; all others need a paid entitlement. If the task becomes 'make enterprise tenants eligible,' the implementation and tests may pass while the promise changes.
Visual: The diff is only the middle.
2. Map three rails.
Intent records the source, tenant, expiry and owner. Build evidence ties protected allowed-and-denied tests to the commit digest. Operation reads the bounded customer cohort after deployment. Each rail can fail or be unverified independently; a green build cannot replace a missing source decision.
Visual: Intent, exact build and operation.
3. Make the forbidden case visible.
Run the migration tenant through the actual UI and API, then a non-entitled tenant through the same path. After a bounded canary, read back the user-facing result and rollback signal. If the migration cohort was not exposed, mark operational evidence inconclusive rather than celebrating a quiet dashboard.
Visual: Test both who gets access and who does not.
4. Accept outcomes, not output volume.
Require every meaningful release to name the promise, exact artifact, independent evidence and post-release observation. Do this because an agent team can produce more finished-looking software while the business loses the thread of what it actually agreed to deliver.
Visual: The customer agreement is the anchor.
