+**Summary**
+
+Status: Behind 20+d
+Deadline risk: CRITICAL
+
+**Notes**
+
+- **⚠️ CRITICAL — Issue #2597 (Priority/Critical, State/In progress, MoSCoW/Must have)**: `fix(ci): restore all CI quality gates to passing on master — no suppression, no bypasses`. The `master` branch has **failing CI quality gates** (`lint`, `unit_tests`, `e2e_tests`, `status-check` all FAILING). This is the **single highest-priority issue in the entire project**. ALL open PRs are blocked until master is green. PR #2629 (`fix(ci): restore all CI quality gates to passing on master`) is open to address this. Root cause: direct pushes to master bypassed CI (commits `77427bd7d32f`, `8c13e63c750a`, `dd17d0f8e698`).
+- Open PRs: 77 (was 61 on Day 54 end-of-day, +16 net new PRs opened by agents/developers)
+- Open bugs: 480+ (was 324 on Day 54 end-of-day, continued agent-driven UAT/bug-hunt expansion)
+- Milestone completions (as of 2026-04-04 end-of-day): M3 70% (218/311), M4 76% (100/132), M5 75% (126/167), M6 67% (174/259), M7 55% (127/229), M8 15% (88/579), M9 28% (105/373)
+- Session 3 remains active with 16 parallel workers and ~71 total concurrent agents
+- Agent-driven issue expansion continues: v3.2.0 now has 93 open issues, v3.7.0 has 491 open issues, v3.8.0 has 268 open issues
+- Highest-issue number seen: #2782 (open), indicating continued rapid issue creation by agents
+- PR #2629 addresses: format violations, A2A JSON-RPC 2.0 migration incomplete test updates, and other CI failures — no quality gates suppressed or bypassed per acceptance criteria
+- New spec updater session state issue #2753 created (ca-spec-updater agent monitoring)
