Owner decision 2026-10-10. Eight items were livelocked in the nvenc tier, burning ~3.3
GPU-hours per pass (initial encode + quality+2 retry) and never converting: they missed the
mean bar by 0.2-1.7 thousandths (0.9626-0.9778) while keeping only 0.20-0.93% of frames
below 0.85 - and per this repo's own comment the FRAME-SHARE test is the one that actually
catches a defect, the mean bar splits a continuum. With SIZE_CEIL=1.0 the mean bar is
unreachable for them by construction.
- library_run.py: POLICY (C:\AI\transcode-run\gate_policy.json) with
* accept - named items are judged by the frame-share test; a mean under the bar is logged,
not enforced. An item that trips the frame-share test is refused even if listed
(0912 洞见, 1.33%, is deliberately absent).
* park - failed quality ROUNDS per item; at PARK_AFTER=2 the item is skipped with a
visible SKIP status instead of being re-encoded. Counters persist in the same file.
- scripts/build_gate_policy.py: builds that file from the run log, taking each key verbatim
from the '--- i/n <relative path>' line (no hand-copying). Result: 7 accepted, 1 refused.
- run/relaunch_nvenc.sh: start the GPU tier ALONE (relaunch_tiers.sh hardcodes both tiers).
- STATE.md: the policy, its rationale and the round counter.

# run/relaunch_tiers.sh hardcodes `for t in x265 nvenc`, so it cannot be used to start the GPU tier

# alone; this is its nvenc-only twin. One lock per tier (C:\AI\transcode-run\run-nvenc.lock, and

# 2026-10-10: the run is governed by C:\AI\transcode-run\gate_policy.json (owner decision):
|
|
# accept = items where the FRAME-SHARE test is the verdict and the mean bar only a warning
|
|
# (7 items that failed by 0.2-1.7 thousandths of mean while keeping 0.20-0.93% of frames
|
|
# below 0.85; 0912 洞见 at 1.33% is deliberately NOT on the list and keeps being refused)
|
|
# park = failed quality ROUNDS per item; at PARK_AFTER=2 the item is skipped instead of
|
|
# re-encoded, which stops the ~3.3 GPU-hours/pass those items used to burn. Clear an
|
|
# item's entry there to retry it.

# Detached because a Hermes-scoped job dies with the session (measured 2026-10-08). No exit

# notification: watch /d/tmp/xcode/run_nvenc.log. Stop by PID only, never by image name.
