conductor(state): fix_mma_concurrent_tracks_sim_20260627 SHIPPED
Track complete. All 7 VCs pass: - VC1: test_mma_concurrent_tracks_execution passes in isolation - VC2: Tier 3 of the batched test suite shows 0 failures (verified 5 consecutive PASS runs at 7.49-8.45s) - VC3: No diagnostic stderr lines remain in src/app_controller.py - VC4: OUTSTANDING_MMA_TEST_FAILURES_20260627.md updated to RESOLVED - VC5: TRACK_COMPLETION_fix_mma_concurrent_tracks_sim_20260627.md written - VC6: No git restore/checkout/reset/stash used - VC7: All atomic commits have git notes (per workflow.md) Two fixes shipped in this track: -e9919059: TrackMetadata import (production bug, NameError on models.Metadata call site at app_controller.py:4830) -913aa48c: Mock sprint routing (session_id-based was fragile; replaced with prompt-content-based) Parent branch tier2/post_module_taxonomy_de_cruft_20260627 is now ready for merge after this fix track is reviewed.
