All tier-3-live_gui tests now pass. Track complete with 5 fixes:
1. e9919059: TrackMetadata import (production NameError)
2. 913aa48c: Mock sprint routing (session_id-based was fragile)
3. fad1755b: Mock epic catch-all (literal-substring was fragile)
4. d28e373e: Mock worker fallback (stale session_id leaked)
5. 55dae159: Remove 'refresh_from_project' task (was overwriting
self.tracks with a disk read returning 0 tracks in batched env)
Verified:
- test_mma_concurrent_tracks_execution: PASS
- test_mma_concurrent_tracks_stress: PASS
- 15 wider tests: PASS (237.63s)
- 3 consecutive runs of the failing combination: PASS (100s each)
OUTSTANDING_MMA_TEST_FAILURES_20260627.md updated with section 7
documenting the refresh_from_project bug and fix.

runs. Track status: active (final SHIPPED commit pending TRACK_COMPLETION

The parent branch tier2/post_module_taxonomy_de_cruft_20260627 is now
ready for merge after this fix track is reviewed.
