Frank: still corrupted at ~40k with --no-enable-prefix-caching deployed and mechanically verified (zero gdn_hip faults in the container serving that window, coherent 40,771-token boundary probe). The recurrence is FAULT-FREE, so the align-mode page re-seed is not the (only) mechanism and the mitigation bought whole-history re-prefill per turn for nothing. Revert: knob FRANK_PRIMARY_NO_PREFIX_CACHING commented out -> the serve branch renders --enable-prefix-caching (the shipped contract). The knob, the branch and the seam stay documented for a future fixed fork build. Open hypotheses recorded in the runbook: re-fed poisoned transcript (the same conversation cannot distinguish fixed from unfixed), or a second fault-free long-context path — fp8 KV at depth is the next suspect. Next diagnostic: fresh-conversation reproduction, then a KV-dtype A/B.

# measured capture cost (VLLM_CUDAGRAPH_MEM_BASE_MB / _PER_GRAPH_MB, container
|
|
# env — the analytic default charges 0.55 GiB where capture took 0.31 GiB, so
|
|
# the 0.24 GiB difference goes to the arena) and raises util 0.98 -> 0.982,
|
|
# Frank's cap. The native-262144 and fp8+MTP4 shapes are retired to
|
|
# git tag frank-primary-fp8-mtp-20261001.

|
|
# THE COMPILE CACHE IS MOUNTED, and that is a boot-cost fix, not a tuning knob:
|
|
# the image ships no /root/.cache at all, our first boot writes 1.1 GB of vLLM
|
|
# AOT/torch_compile artifacts plus 229 MB of comgr JIT kernels into the
|
|
# container's ephemeral layer, and `podman rm -f` deletes them — so every
|
|
# deploy/restart/reboot re-pays `torch.compile took 181.20 s in total` (173.19 s
|
|
# of it one graph). Mounting FRANK_PRIMARY_CACHE_DIR at /root/.cache makes all
|
|
# later boots load the compiled artifact instead, and hides nothing. PROVEN
|
|
# LIVE 2026-10-02 on consecutive boots of this shape: cold `torch.compile took
|
|
# 188.26 s`, warm `Directly load the compiled graph(s) for compile range
|
|
# (1, 1024) from the cache, took 2.143 s` / `torch.compile took 3.97 s in
|
|
# total` / `init engine … took 41.13 s (compilation: 3.98 s)`.
|

#
|
|
# The root unit (scripts/frank-primary.service, User=dank,
|
|
# LimitMEMLOCK=infinity) grants the pin budget for the tiered-expert host
