docs(validate): positioning per-pillar verdict

[rickylabs]

Part of #401 · Depends on #433 (S0) and the D-pillar authoring slices (D1–D9)

Handle: V-D · Milestone: 0.0.1-beta.7 · Lane: OpenHands, qwen 3.7 max, separate session (doc-authoring exception: the workflow is generator-only and does not self-certify).

Scope — positioning per-pillar validation verdict

Per-slice verdict checks (per D pillar)

• deno task verify green (build + check:links + check:caveats).
• Every present-tense API/capability claim traces to deno doc (accuracy worklog line each).
• Positioning-law grep: no honest/honestly/candor, no throughput/X% faster, no superlatives, no _plan-lifted phrasing.
• No page orphaned from nav.
• Verdict PASS / CHANGES_REQUESTED per pillar; two fail-cycles → escalate.

Design source: design/CD-docs/epic-and-issues.md (§5, V-D).
