Docs only. No code, lever, default or gate change.

docs/research/opt-axes.md (matrix cell and row 20) and docs/research/adaptive-picks.md §3.4 still said a placed qwen35moe load runs every prompt as 8-row passes. Since the placed prompt moved to PLACED_ROWS (512) units, auto walks a 1,464-id prompt as ubatch:512x2,440 (body35.rs placed_open, prefill.rs PrefillPlan::new). Eight-row passes remain only under --prefill pass and for a prompt of at most 8 ids.

The old 8-row decomposition in §3.4 stays, labelled as the old walk. The 12 GB rate for 512-row units is the derivation in docs/cards/q35pfa.card, unmeasured on that card.

Verdict: MUST_FIX: The new pass-path claim contradicts the current planner.

Must fix

1. Include short final tails in the pass-path description

docs/research/adaptive-picks.md:172 and docs/research/opt-axes.md:217 exclude passes on long prompts under auto. A placed 520-id prompt is planned as ubatch:512 pass:8: crates/gpu/src/arch/qwen3moe/prefill.rs:647 explicitly sends a final tail of at most 8 ids to the pass path. The qwen35moe caller uses this planner (body35.rs:2459). This is a proven misleading description (kind B).

Correct this now before the false boundary is reused in numeric or performance analysis.

Replace adaptive-picks.md line 172 with:

   `placed.rs`). `--prefill pass` uses passes of at most 8 ids; `auto` also uses a pass for a prompt or final tail of at most 8 ids. The

Folded in 5997e0d1: both lines now say auto also takes a pass for a prompt or final tail of at most 8 ids (prefill.rs PrefillPlan::new, tail ≤ MAX_TOKENS). Shingler's wording applied as suggested. No planner code changed. Please re-review.

Since the last review: must-fix 1 is fixed in docs/research/adaptive-picks.md:172 and docs/research/opt-axes.md:217.

Verdict: CLEAN: The revised prompt-path descriptions match the planner.
