docs(vault): de-stale the quant and swap method pages

Parent-written (scout summaries were corroborated against the files, not
trusted): every restatement of an endpoint shape now cites the endpoint page,
and four claims contradicted by today's fleet state are corrected.

- Quantization Production: the challenger-contract line quoted the retired
  compaction-hub window; now cites [[frank-zealot]]'s Current shape. The 3090
  worked example is era-tagged. Sources listed [[frank-dragoon]] three times.
- Quantization by Hardware Architecture: said the 3090 lives on Dankserver
  (it moved to Dankclaw 2026-09-16; the Eras table owns the move) and ranked
  the retired Ling-3.0 Quark INT4 service as the ACTIVE Dankclaw workload. The
  active service is [[frank-dragoon]] on a closed `.hgn` format.
- GGUF Compatibility: Related claimed the ftype-115 ROCmFPX file was "in
  production"; that is an era now, so it points at [[kingjones-q8agent-rocmfpx]].
- Model Swap and Rollback: dropped the fragment byte-count ledger (AGENTS.md
  owns it), the Ampere FP8 hardware claim ([[Quantization by Hardware
  Architecture]] owns it), halogen's HTTP surface ([[frank-dragoon]]'s wire
  contract) and three brittle unit-file line refs (accepted loss: line numbers
  are derivable, the root-unit law stays). Fixed the per-slot example, which
  described the retired 3-slot arithmetic, and a Related bullet that called
  [[frank-archon]] retired while linking the same page twice.

Census over the diff: 1 orphan line, the deleted unit line-number refs above.

 ### Dankclaw (Strix Halo gfx1151, RDNA 3.5)
 
-RDNA 3.5 has no native FP8 tensor cores. The APU shares memory. The active Ling-3.0-flash service runs vLLM-ROCm with the AMD Quark INT4 (W4A16) format (the jcbtc CIRU Strix-native bundle). INT4 weights keep the 124B model inside the 96 GiB frame buffer with a full-precision KV cache.
+RDNA 3.5 has no native FP8 tensor cores and the APU shares its memory, so the
+GPU budget is the GTT aperture and every live figure on the box is
+[[Dankclaw System Specs]]. What serves here today is [[frank-dragoon]]: a
+vendor `.hgn` checkpoint, a format this page cannot rank because no public
+quantizer exists for it ([[Quantization Production]]).

-| 1 | INT4 W4A16 (Quark/vLLM) | active; fits 96 GiB; native ROCm kernels; concurrency |
-| 2 | MXFP4 (Quark) | same-bit, higher accuracy; beta on gfx1151 (A/B experiment) |
-| 3 | GGUF Q4_K_M / Q8_0 | works with upstream llama.cpp only |
+| 1 | `.hgn` (deployed) | the halogen engine's own format; production door is closed |
+| 2 | GGUF K/I quants, K_P blends | the only self-produced option on this card ([[Quantization Production]]) |
+| 3 | INT4 W4A16 (Quark) / MXFP4 (Quark) | the retired Ling-3.0-flash vLLM era, measured under the firmware-VGM frame buffer: [[ling-3.0-flash-trial]] |
 | 4 | FP8 (vLLM) | software emulation; memory savings only; no compute win |
