_tests.rs
When human contributors follow CONTRIBUTING.md:38-40, they are still explicitly told to create test.rs, while the example plan likewise names src/retry/test.rs and src/error/test.rs. Those instructions now directly conflict with this repository-wide naming rule, so the same change should update those references to prevent new work from being noncompliant by construction.

Replace the unavailable externalizer instruction with manual migration steps.
OpenHuman/scripts/externalize-inline-tests.mjs is not available in this checkout. The identified check-openhuman-rust-layout.mjs only reports layout violations; it does not move tests. No alternative migration command is documented, so contributors cannot follow this instruction to perform the required migration.

Tiny Sweeper reviewThis pull request updates AGENTS.md to mandate that unit tests reside in `*_tests.rs` files, replacing the previous `test.rs` convention. It adds detailed instructions for test file naming, placement, and migration. However, the review identifies an inconsistency: CONTRIBUTING.md still references the old naming, which should be updated to avoid contributor confusion. State: Incomplete Review snapshot
Completeness: Incomplete What changedModified AGENTS.md: changed the test file location guideline from 'test.rs' to '*_tests.rs', and added a new section 'Tests live in `*_tests.rs` files' that specifies naming rules, placement (e.g., `<module>_tests.rs` beside `mod.rs`), use of `#[path]` attribute, and a script for externalizing inline tests. Features
TestsNo supported feature-to-test mapping was produced. Test execution is not inferred. FindingsPreviously reported and still active

Replace all `assert!(x.is_empty())` calls with `assert_eq!(x.len(), 0)` across test files to improve diagnostic output on failure, as the length-based assertion shows the actual value when the assertion fails. Auto-committed-on: dragonfly
Reformatted several test assertions that were written as single long lines into multi-line expressions for improved readability. The changes are purely cosmetic and do not alter any test logic or behaviour. Auto-committed-on: dragonfly

This commit edits seven legacy test.rs unit-test files while leaving their filenames and mod test; declarations unchanged. The newly added repository rule explicitly requires each legacy file to be renamed to <module>_tests.rs with a #[path] declaration when it is next touched, so these edits immediately violate the policy they introduce; rename all touched unit-test files and update their module declarations in this change.
