CTX_SIZE=1048576 / PARALLEL=4: every slot gets the model's full trained window. Measured fit arithmetic on the 3090: 1 full-context slot idles at 11,996 MiB, 4 at 22,346 -> 3,450 MiB per slot, ~8,546 MiB fixed. A 5th slot projects 25.8 GiB past the 24,576 MiB card, and the KV pool allocates upfront, so 4 is the ceiling. Explicit CTX_SIZE bypasses --fit on purpose: fit maximises the TOTAL pool and would divide a smaller window across slots at parallel>1. The slot-grid seam now pins both the full-window division and the budget inequality so a future capacity bump fails pre-deploy, not in the boot allocation. Audio verified while measuring: the mmproj's audio encoder transcribes input_audio parts verbatim (JFK WAV sample). Header comments updated.

# Seam: the frank-small mainline-llama.cpp root unit on dankclaw.
|
|
# frank-small is the RTX 3090 endpoint created on 2026-09-16, when frank-large
|
|
# went back to the halogen engine on the iGPU. This seam pins what the flags
|
|
# alone do not say: boot persistence for a NATIVE runtime (no generated quadlet
|
|
# is involved), the repo-relative paths the unit executes, the separate client
|
|
# port, the MTP contract (the head is a separate sidecar file loaded as the
|
|
# draft model, chained behind ngram-mod), the vision handoff from frank-large,
|
|
# and the KV budget: q8_0 quantized KV whose context --fit sizes to the card.
