# Beta 18 Release Review Disposition

Reviewer file: `.llm/reviews/BETA_18_RELEASE_REVIEW.md`

## Blocking Finding Disposition

The reviewer correctly flagged `compiler/src/main.rs` test-runner stack/thread
hardening as release drift while it was undocumented. The controller kept the
change because `cargo test --test promotion_gate` reproduced a host stack
overflow in `std-layout-local-vec_i32` without it, making the release gate
unreliable.

Resolution:

- `docs/compiler/RELEASE_NOTES.md` now lists the bounded worker-stack behavior
  in the `1.0.0-beta.18` summary.
- `docs/compiler/ROADMAP.md` now records the same behavior as beta18
  test-runner hardening.
- `.llm/BETA_18_JSON_STRING_TOKEN_PARSING_FOUNDATION.md` now marks it as
  gate-supporting compiler hardening, not a new language feature.
- `cargo test --test promotion_gate` passes after the fix and failed with host
  stack overflow before the fix.

Verdict after disposition: release may proceed if the full gate stack passes.
