docs + charts: v7.66 + Cliff 1 mech B closed across all 4 TQ3 composes
Phase 3 of the v7.66 migration: documents the new state, regenerates
performance/VRAM charts, posts cross-rig data to Sander on discussion #19
+ issues #15/#16/#17.
What changed
------------
**docs/SINGLE_CARD.md**
- Updated TL;DR table: long-text 180K + 0.95, long-vision 145K + 0.95,
bounded-thinking 180K + 0.95.
- Removed Cliff 1 mech B "limitation to know" — now closed.
- Added "What was Cliff 1 mech B (now closed) ✅" historical note.
- Updated activation budget rationale to reflect PN12+PN25 pool residence.
**docs/DUAL_CARD.md**
- Bench protocol substrate: Genesis v7.65 → v7.66 dev tip.
**docs/CLIFFS.md**
- "vLLM pin compatibility status" rewritten for v7.66 + Cliff 1 mech B
closure.
- Replaced "v0.20 unblock" prose with "Cliff 1 mech B — what closed it"
section explaining the two compounding fixes (PN25 v3 + PN30 dst-shaped).
- Updated Genesis patches table with PN30 + PN33 + Sander v7.66 PN25.
- Added "Local sidecars retained on master" table — 4 sidecars, why
each one is still needed.
- Updated "Validation across all 4 TQ3 variants" to 2026-05-02 numbers
(180K / 145K / 180K / 262K — all 6/7 probes pass).
**docs/UPSTREAM.md**
- Genesis issue tracker updated with v7.66 cross-rig findings:
- #16 PN25: both v7.65 and v7.66 mechanisms fail on TP=1
- #17 PN30: layout-correctness diagnosis + our corrected fix
- #15 PN31: doesn't fit on 24 GB (lower mem-util sufficient)
- PN33 partial (boot-time closes, runtime decode still fires)
**docs/engines/VLLM.md, README.md, model README**
- Genesis pin references bumped d89a089 → fc89395.
**models/qwen3.6-27b/CHANGELOG.md**
- New entry: "2026-05-02 — Genesis v7.66 + Cliff 1 mech B closed ⭐"
with full validation matrix, sidecar inventory, and links to per-config
result summaries.
**tools/charts/gen-perf.py + gen-vram.py**
- Substrate footnote: v7.65 dev (d89a089) → v7.66 dev (fc89395)
- Compose ctx labels: long-text 214K → 180K, long-vision 198K → 145K,
bounded-thinking 214K → 180K, mem-util 0.985 → 0.95
- Regenerated all 14 chart files (performance + vram, single + dual + combined).
