Frank 500ac2b871 docs(vault): consolidate the vLLM offload-knob claim to one owner (C2, C6)
The "`--swap-space` is removed; use `--kv-offloading-size`" claim was carried by
six pages, two of them with their own copy of the upstream source citation. It
now lives only in [[RAM CPU Offloading in VLLM]], which carries the 2026-10-19
verification against `vllm/config/cache.py` (no `swap_space`; `kv_offloading_size`
activates only with `kv_offloading_backend`):

- `VLLM Overview` (two argument tables), `VLLM Index` (parameter table),
  `DFlash DSpark Speculative Decoding`, `Shared Memory Architecture Dankclaw`,
  `Hybrid CPU GPU Processing Dankserver` -> cite the owner.
- `VLLM Index`'s example command used the dead flag; it now shows the live pair.
- `dankserver-vram-growth`: banner disambiguates the 2026-08 `frank-zealot`
  (llama.cpp on the 3090 when that card was in Dankserver) from today's endpoint
  of the same name on Dankclaw, so a retired crash signature does not read as a
  live fault on a same-card-class service.

vLLM Index

RETIRED (2026-08-18). The vLLM service on Dankclaw was replaced by the CIRU ROCmFPX llama.cpp runtime (v3). These pages are historical reference. See frank-dragoon.
