Code Review Report

Follow-up review after the requested fixes.

Fixed

1. The root-only path restriction is gone.

   • type_check() now accepts nested paths again in crates/monty-type-checking/src/type_check.rs.
   • Nested-path cleanup is covered by exact tests in crates/monty-type-checking/tests/main.rs.

2. Diagnostics are no longer eagerly pre-rendered in every format.

   • Rendering is lazy again via the retained pooled db in crates/monty-type-checking/src/type_check.rs.

3. The benchmark no longer hides internal failures.

   • The REPL-sequence benchmark now fails loudly on internal errors and unexpected type-check failures in crates/monty-type-checking/benches/type_check.rs.

4. The pool-isolation tests now use exact concise diagnostic assertions instead of broad substring checks.

   • Tightened in crates/monty-type-checking/tests/main.rs.

5. The stale SRC_ROOT docstring is fixed.

   • Updated in crates/monty-type-checking/src/db.rs.

Remaining Intentional Behavior

1. pool.rs still uses panic-based fatal paths for internal pool corruption and drop-time cleanup failures.
   • Per user instruction, these were intentionally left in place.

Verification

• Ran make format-rs
• Ran make lint-rs
• Ran cargo test -p monty_type_checking --tests
• Result: all passed
