chore(254): deprecate the now-unused Genesis nightly engines + patches [Phase 3+4]
Phase 3 — engine profiles (zero registry users after the archival):
- vllm-nightly-mtp + vllm-nightly-full -> stability: deprecated + DEPRECATED notes
(both purged nightlies, 404 on Docker Hub). nightly-mtp retained as the
genesis_equipped test anchor (required_genesis:true).
- arch_patches.yml: flipped the qwen3-next-hybrid vllm-nightly-mtp pin
loads:true -> false (deriver won't offer the dead engine; [email protected].0
stays the loads:true primary).
- generate-compose.sh usage example + docs/UPSTREAM.md engine-pin rows updated.
Phase 4 — patches.yml: stamped 55 patches deprecated_on:2026-06-05 (kept on disk):
- the ~46 genesis-p*/pn* env-gated patches (via the &genesis_env_patch anchor)
- 9 dead overlays: sglang x2, pr40798/pr40914 (negative-result), gemma-pr41800
(merged upstream), gemma4-fp8-ampere (Ampere-dead), perheadkv-hybridpage-fix +
pr40391-perheadkv (superseded by pr40391-rebased), carnice-chat-template
(carnice compose archived).
- Left 9 ACTIVE: overlays still mounted by functional composes + the gated
gemma-a4b #326 patch.
42/42 gate green. Refs #254.
