# Action-aware constraint pilot v2 amendment

Status: **FROZEN AFTER V1 CONTROLLER STOP AND BEFORE V2 GPU RUNS**.

Date: 2026-07-14 (Asia/Singapore).

The V1 configuration matrix and every scientific gate remain unchanged.  V2
fixes one controller bug and reruns every configuration and repetition fresh.

## V1 controller failure

The MNS64/MBBT2048 burn-in completed all 510 requests in 61.259 seconds, below
the frozen 90-second operational limit.  However, the controller accidentally
assigned the preceding 16-request warm-up result to `burnin_result`; its state
therefore recorded 4.376 seconds and evaluated the wrong object.

The first measured replay was terminated after 75 seconds, before it produced
a result.  No target configuration had started.  V1 consumed
0.3184109431 H20-hours and contributes no action label or telemetry to V2.

## V2 correction and regression gate

- The completed burn-in `run_client()` return value is assigned to
  `burnin_result`.
- A dedicated `burnin_gate()` rejects any non-anchor object, any request count
  other than 510, and elapsed time above 90 seconds.
- Unit tests explicitly pass a warm-up object and require rejection, then test
  accepted and over-limit burn-ins.
- All five configs and 15 measured runs use a new run root; no V0/V1 runtime
  artifact is reused.

V0 and V1 together consumed 0.7043978426 H20-hours.  V2's incremental hard cap
is therefore 7.2956021574 H20-hours, preserving the original global 8.0
H20-hour cap.  The authoritative accounting file is
`runs/action-aware-v0/prior-attempts-v2.json`.
