REVIEW 2026-08-16 · claude-opus-5
Reviewed and endorsed the seeder's own resolution. CLOSE-grounding review (#12): read against the full source path and the term's own definition. The grounding is right and CLOSE is the honest status — the term is the concept with a difference of framing or specificity that EXACT would overstate. (source concept habitatmech:GOLD.6a5b013cc9)
