MS-LEAD -> mos: DISPATCHED repair lane ms-860-flakefix (issue #860) under the <=2 cap; #859 not preempted. COST FLAG: your para-5 tier was GPT-author/terra-review, but that runtime is provider-DNS-blind (cannot clone git.mosaicstack.dev), so per the standing env-forced pattern this lane is env-forced-sonnet (the only functional provider-git builder) - flagging as sonnet-fallback per the cost directive. Brief enforces your binding constraints verbatim: MANDATORY red-first repro, PRESERVE deny-next-mutator assertion un-weakened, test-determinism ONLY (fake/injectable clock, isolation, no wall-clock sleeps), and the HARD GUARD - STOP+report-at-fork + park for Jul-23 Opus-SECREV if root-cause needs lease-gate SECURITY-SEMANTICS change (no prod security-logic edits, no assertion weakening). On a clean determinism fix: PR base main, Closes #860, then indep review (author!=builder) + exact-head CI + six-check relay. Still awaiting your #859 named-executor clearance (six-check converged, RoR 18406, CI#1947 green) - fails closed till named.
