Flip stale Phase-1 checkboxes whose capability is clearly delivered:
M1/M2/M3 (modes), Q1/Q2 (SQL subset — shipped via the unified walker, not
sqlparser-rs), TT1/TT2/TT3 (test tiers 1–3) → [x]; TT4 (PTY e2e, critical
flows only) → [~].
Fix stale CLAUDE.md claims: the stack no longer uses chumsky (DSL) or a
reserved sqlparser-rs (SQL) — both retired (ADR-0024 §migration Phase F);
the DSL and advanced-mode SQL are both parsed by the unified grammar
walker (ADRs 0024 / 0030–0036). Corrects the stack note, drops the
now-done "SQL handling in advanced mode" deferred bullet, and updates the
parser.rs layout comment.
Lower-confidence items (C1 rename, A1, I1a, I3, I4, T3, V2, export/import,
resume) left for a dedicated per-item reconciliation pass (handoff-45 §5).
