# Static-policy oracle-gap protocol
Status: **FROZEN BEFORE NEW GPU EXECUTION**.
Status: **FROZEN WITH A-OG-1 AMENDMENT**.
Date frozen: 2026-07-13 (Asia/Singapore). Existing Phase-3 measurements were
inspected only to choose the workload pair and rate brackets. They are
exploratory calibration data, not primary observations in this protocol.
### A-OG-1 — extend the P06 upper bracket (after trial 33)
The controller stopped as registered after C00/P06 remained SLO-feasible at
every original and upward-extension anchor through 2.3 requests/s. At that
point 33 trials and 1.519475 H20-hours were complete, all GPU memory had been
released, and no C00/P06 infeasible upper bound existed. No oracle inference
was performed.
This amendment changes only the P06 upward-extension list from
`2.1,2.2,2.3` to `2.1,2.2,2.3,2.4,2.5,2.6,2.8,3.0`. The controller stops at
the first bracket exactly as before. Existing trials are immutable and are
reused; config order, P01 rates, SLO, timelines, repetitions, placement,
metrics, and decision threshold do not change. The resumable controller may
accept the new code/protocol fingerprint only when all immutable runtime,
client, model, manifest, config, and base-grid fields match the pre-amendment
state, and it records both fingerprints under `A-OG-1`.
