+Deadline risk: CRITICAL

+**Notes**

+- Day 102 update (2026-04-12, cycle 1). Session 4 active (issue #4799, 32 parallel workers, full supervisor fleet). Open PRs: 225→257 (+32 new agent-driven PRs). Open bugs (Type/Bug label): ~25→3 (major bug-fix wave since Day 100).
+- Milestone scope continued to expand since Day 100: M3 grew from 770→948 (+178), M4 grew from 220→233 (+13), M5 grew from 313→345 (+32), M6 grew from 1085→1181 (+96), M7 grew from 400→433 (+33), M8 grew from 944→956 (+12), M9 grew from 475→489 (+14). New v3.9.0 milestone added (17 total issues, 4 closed).
+- Milestone completions (Day 102): M3 28% (262/948, was 32% at Day 100 — scope expansion outpacing closures), M4 46% (108/233, was 49%), M5 40% (137/345, was 43%), M6 17% (201/1181, was 18%), M7 35% (152/433, was 38%), M8 45% (427/956, was 45% — stable), M9 27% (132/489, was 28%).
+- Significant bug-fix wave: open Type/Bug issues dropped from ~25 to 3 (issues #7989, #7991, #7992 — LockService not wired into plan lifecycle, ServiceRetryWiring dead code at runtime, UKOQueryInterface.get_resources_by_layer never returns resources). All three are Priority/Critical.
+- Open PRs grew from 225 to 257 (+32) as agents continued opening fix/feature PRs. PR #7957 (bug-hunt-pool-supervisor tracking prefix fix) is open and awaiting merge.
+- All milestones M3-M7 remain overdue. M8 and M9 have no deadlines and are in active development. Agent-driven issue creation continues at high velocity across all milestones.
+- v3.9.0 milestone newly created (2026-04-10) with 13 open and 4 closed issues — documentation and feature updates scope.
