  "notes": "Two DONE_WITH_CONCERNS on Task 2: (1) plan-ordering defect — check_fn loop_stack declaration+threading had to move from Task 4 into Task 2 because Task 2 Step 4's cargo-build 0-errors gate is unsatisfiable while check_fn is an unthreaded synth caller; resolved by executing the plan's Task-4 Step-3 block verbatim at the gate-forced point, only the verify_loop_body invocation stayed in Task 4. (2) recon under-counted cross-module synth callers (builtins.rs x2, lift.rs, mono.rs x2) — mut.2-class recon-undercount, resolved by mirroring the mut.2 fresh-stack pattern; the compile-driven sweep was the plan's designated exhaustive oracle. Zero review re-loops; all three Boss design calls implemented verbatim. cargo test --workspace 608 -> 616."
