[rickylabs]

Closes #449
Closes #450

Run-artifact PR: the GPT opposite-family validation session's verdict tables at .llm/runs/docs-449-450-validation--gpt/verdicts.md.

• docs(validate): positioning per-pillar verdict #450 (per-pillar positioning): PASS — all nine pillars pass shape, positioning-law, sampled API-trace (≥3 load-bearing claims per pillar traced to workspace/published source), link/caveat, and stale-version gates.
• docs(validate): tutorial-rewrite per-track verdict #449 (per-track tutorials): initial verdict FAILED three tracks on honesty framing (storefront, erp-sync, eis-chat); fix loop PR docs(tutorial): remove honesty framing flagged by the #449 validation verdict #652 merged; re-verdict PASS on all six tracks (re-verdict section in verdicts.md, evaluator commit 5b37f17e).
• Shared evidence: deno task verify on merged main green (24,055/24,055 links across 167 pages; 28/28 caveats); scoped stale-claim scan clean.
