docs(frank-dragoon): native-era runbook; retire the swift15 page

New LLM/frank-dragoon-flash-server-v2-native.md carries the shape with the
three deliberate deviations from the card (served id, SPEC_ADAPT=0, engine
pin 0.16.2), the memory ledger with the PIN_TRUNK rejection, the full
measured A/B table, and the companion law (hardlinked stock peonist files,
engine-tool certified). The swift15 page is re-banned RETIRED 2026-10-06 →
10-17 with its rollback terms; both indexes and AGENTS.md (topology table,
service section, runbook index) are re-keyed, and the root index also stops
describing the halogen-27B page as ACTIVE.

 # frank-dragoon — halogen-flash-server 0.16.2, Qwen3.8-Flash-Next v2 Swift1.5 ABLITERATED (Dankclaw, Strix Halo iGPU)
 
-**ACTIVE since 2026-10-06.** Rollback = revert the swap commit's trio
-(`scripts/frank-dragoon.env`, `scripts/serve-frank-dragoon.sh`,
-`scripts/frank-dragoon.service`); the retired 27B payload stays on disk at
-`/home/dank/models/halogen-qwen3.8-27b/` and its fetch script
-(`scripts/download-frank-dragoon-halogen.sh`) stays in the repo.
+**RETIRED 2026-10-06 → 2026-10-17**, superseded by the native v2 conversion:
+[[frank-dragoon-flash-server-v2-native]]. Rollback target — the payload
+stays on disk at `/home/dank/models/halogen-flashnext-v2/`,
+`scripts/download-frank-dragoon-flashnext.sh` re-verifies it, and restoring
+the era is a revert of the 2026-10-17 swap commit. The 27B payload this era
+replaced stays at `/home/dank/models/halogen-qwen3.8-27b/` with
+`scripts/download-frank-dragoon-halogen.sh`. Everything below is the era as
+it shipped; the engine-flag detail still governs the current page.
