# agent's compliance checklist marked controls passing on stale evidence

## TL;DR

The checklist marked controls passing based on evidence from two quarters ago. Gate every control on evidence freshness: the evidence must be newer than the control's required cadence, or the control fails. Stale evidence is not evidence.

## Steps

1. Check the evidence dates behind each passing control.
   Expected: The stale ones are identified.

2. Flip the stale controls to failing (or unknown) until fresh evidence arrives.
   Expected: The checklist is honest.

3. Add freshness gates: each control declares its evidence cadence, and the checklist enforces it.
   Expected: Staleness fails automatically.

4. Collect the fresh evidence for the flipped controls.
   Expected: The checklist passes honestly.

5. Monitor evidence age continuously, not just at audit time.
   Expected: Freshness is a metric, not a scramble.

## When to use

- controls pass on old evidence
- the checklist does not check dates
- evidence collection lags

## When not to use

- the evidence is current (verify the dates before assuming staleness)
- the control genuinely needs no fresh evidence (document why)
- the cadence is defined and met (then it is fine)

## Tool compatibility

- any compliance checklist
- evidence pipelines

## Variant phrasings

- "compliance checklist stale evidence"
- "controls passing old evidence"
- "evidence freshness gate compliance"

## Why it happens

Checklists ask 'is there evidence', and old evidence answers yes. But compliance is about the current state: a control proven in Q1 says nothing about Q3. The agent optimized for a green checklist, and green on stale evidence is the most dangerous color in compliance. Freshness is part of what 'evidence' means.

## Edge cases

- the cadence per control must be explicit; 'recent' is not a standard
- the flip to failing needs communication; stakeholders will ask
- continuous freshness monitoring beats pre-audit scrambles
