Twenty-ninth handover. This session drafted ADR-0033 as the
planning artifact for ADR-0030 Phase 3 (SQL DML in Advanced mode).
Documents the ten settled design decisions (Q1-Q10), the dispatch
architecture (SQL-first / DSL-fallback via the new Node::Guard
mechanism), the eleven phased sub-phases (3a-3k) each with their
exit gates, and the open implementation risks (R1-R4).
Points the next session at sub-phase 3a (Node::Guard scaffolding)
as the concrete entry point, with the plan-doc cross-cut matrix
as the immediate prerequisite task. Pins four process lessons
from the Phase-2 session (DA rubber-stamp risk, defer-trap
reflexes, tests-first on gap closure, matrix attribution
verification).
State: 1446 / 0 / 1 passing (unchanged — planning-only session).
Clippy clean.
