Added row 34 to conductor/tracks.md tracking the Phase 3 provider state
call-site migration track. SHIPPED 2026-06-25 by Tier 2 autonomous mode.
9 phases, 11 tasks, 16 atomic commits. 12 module-level aliases removed;
26 call sites migrated across 6 per-provider phases. 7/7 audit gates
pass; 64 per-provider regression tests pass; effective codepaths
unchanged at 4.014e+22.
