Agents can ship the wrong agreement faster. The worker may not silently rewrite it. The source decision is the oracle. #EricFieldNotes

Full written post / accessibility read

A fictional SaaS customer gets migration-only feature access. A shortened brief reaches three agents as 'enable enterprise access.' They implement and test that sentence accurately. The product failure happened before the patch: the one-tenant and expiry clauses fell out of the handoff.

Record source, affected tenant, allowed and forbidden behavior, expiry and decision owner. Link each acceptance assertion to that source. The UI and API tests must cover the migration tenant and a non-entitled tenant. A worker can propose a policy change, but the owner must approve a new contract first.

Release the exact build to a bounded cohort. Verify that the migration tenant gets the promised access and an ordinary tenant remains blocked. Compare with a control group and pause if the relevant cohort is absent or the signal is inconclusive. A generic error-rate chart is insufficient.

My rule: bind source-linked product intent to the exact artifact, independent tests and a bounded live observation. Do this because more code speed is wasted if the organization proves the wrong agreement and calls it progress.

Four-beat scene transcript

1. Agents can ship the wrong agreement faster.

A fictional SaaS customer gets migration-only feature access. A shortened brief reaches three agents as 'enable enterprise access.' They implement and test that sentence accurately. The product failure happened before the patch: the one-tenant and expiry clauses fell out of the handoff.

Visual: The tests can be honestly green.

2. Treat intent as protected data.

Record source, affected tenant, allowed and forbidden behavior, expiry and decision owner. Link each acceptance assertion to that source. The UI and API tests must cover the migration tenant and a non-entitled tenant. A worker can propose a policy change, but the owner must approve a new contract first.

Visual: The worker may not silently rewrite it.

3. Check the deployed promise.

Release the exact build to a bounded cohort. Verify that the migration tenant gets the promised access and an ordinary tenant remains blocked. Compare with a control group and pause if the relevant cohort is absent or the signal is inconclusive. A generic error-rate chart is insufficient.

Visual: Production can reveal a cohort the test missed.

4. Make alignment measurable.

My rule: bind source-linked product intent to the exact artifact, independent tests and a bounded live observation. Do this because more code speed is wasted if the organization proves the wrong agreement and calls it progress.

Visual: The source decision is the oracle.
