Why: The 2026-10-13 login recovery flow was approved and merged
(Backend #187, Frontend #76, Dev #504); the master proposal must carry
the three adjudications, implementation record, and evidence pointers
per the repo's lineage conventions.
Evidence: Dev #504 HEAD CI (test/test-pg/svc-realcombo) success; browser
acceptance receipts be7ae9a2/b3a9e691 bound to Dev HEAD 268ef29 (SELF).
Impact: r3 is an implementation record only; R/KTD/U numbering semantics
unchanged; U7 explicitly NOT marked complete (atomic bootstrap and CLI
credential delivery remain). INDEX.md status line updated.
