Per analysis/unified_routing_fix_review.md #2, several docs still presented the retired single-argmin + PUSH-migration design as the final algorithm. Mark them superseded and document the current hybrid direction (commit255c8e6). - REPORT.md §1.1 / §3.9: add errata callout and section header noting the "Final Design" framing was retired aftercc6e562/ 4c583f2; point readers to docs/migration-policy-design.md. - docs/migration-policy-design.md: rewrite. Opens with the current hybrid algorithm (LMetric base + cache_ratio>0.5 affinity gate + tie-breaker), then a "What Was Retired" commit table, then the old Approach A numbers preserved as "Historical Baseline-Mode Comparison". - analysis/research_findings.md §2.2 / §5: correct the LMetric framing. LMetric isn't "neutralized by affinity constraints" (pure --policy lmetric has no affinity at all); it converges to similar placements because P_tokens includes new_uncached_tokens, giving it implicit soft affinity. - analysis/elastic_hypotheses.md: same LMetric correction in the "DOESN'T work" summary, plus a footer cross-referencing the current routing direction. - analysis/unified_routing_fix_review.md: track this file (was untracked); it is the review handoff cited from the updated docs.
