---ci--- phase: 7 milestone: v0.2 status: complete requirements: covered: [REQ-2-001, REQ-2-002, REQ-2-003, REQ-2-004, REQ-2-005, REQ-2-006, REQ-2-007, REQ-2-008, REQ-2-009, REQ-2-010, REQ-2-011, REQ-2-012] partial: [] ---/ci--- Milestone v0.2 (ai-tutor-architecture) merged to main. Escalation record (audit remediation, durable): P1 executor delegation failed twice (empty subagent results, zero files created); auto-resolved at full autonomy to inline execution with identical plan fidelity (commit 3271373, reflog-only after phase branch squash-delete).
