#862 stage 1: H3 quality-ramp section in minimax-h3 quality-and-speed reference #882

Stage 1 of #862: Stages → Stage 1 of plan v2. The plan is authoritative; this restates it.

Builds

• A ## Ramp section in plugins/dw/skills/minimax-h3/references/quality-and-speed.md, which expands the "Draft then final" bullet (:42). It holds only what the file lacks:
  1. Pick the path by target before the first render.
     • TV: L1 → L7. L0 is a throwaway sketch whose staging won't carry.
     • Cinema: B3 → L5 by arguments, or P1 via a saved copy with cache added until feature: H3 templates - expose attention_backend + cache everywhere, and a quality tier preset that sets the coupled knobs together #865 lands. Note which templates take sage_hub as an argument.
     • Close-ups: ship the 12-step draft.
     • L7 is marked "not confirmed by ear or in playback".
  2. Carryover: a pointer to the existing invariants, plus "same seed/canvas/prompt" and "blocking carries, props sometimes don't". Each claim states its seed count from H3 quality ramp: follow-up experiments (seed stability, cross-family composition lock, int4 base draft) #861.
  3. What to approve at the draft and at the final; re-roll only at the draft.
  4. How to judge: face crops (get_output_frames), a contact sheet, check-script, a 1–5 set_note score, and what Claude can't judge (audio by ear, motion).
  5. Cost: quote plan.estimate once plan.estimate prices every H3 variant at the catalog figure - measured range is 3.5-44 min #866 lands, the ladder until then.
• plugins/dw/skills/minimax-h3/SKILL.md: reword the "Smeary faces" line (:100) to cover quality tiers. Add no new line; the file must stay under 12,288 bytes (the :173 trim is available).
• plugins/dw/skills/script-to-video/SKILL.md: a one-line pointer for H3 shots in the test-render-then-set_note passage.

Owes

• Tests: no new test. tests/test_plugin_skills.py stays green.
• Docs: the section itself, plus a plugin version bump.

Deploy

Plugin-only. No server restart.

Blocked by

#861 (seed results for the carryover claims). Fallback if #861 is declined: ship with "measured on one seed" against each carryover claim.

Passes when

The plan's acceptance intent holds (draft and final argument sets validate clean and differ only where the section allows, the attention_backend/cache checks, and the lora_disabled refusal case), and every pending: #<this issue> case the tester writes passes.
