For every new *_tests.rs, this requires the file to start with use super::*;, while the Documentation section requires the same file to start with a module-level //! comment. No file can satisfy both literal requirements, so specify that the import follows the required module documentation (and any inner attributes).

Tiny Sweeper reviewThis pull request updates documentation rules and replaces `.is_empty()` assertions with explicit `.len()` comparisons in three test files. No behavioral changes; safe to merge. State: Incomplete Review snapshot
Completeness: Incomplete What changedThe diff touches documentation and test files: AGENTS.md adds a new section 'Tests live in *_tests.rs files' and updates existing file naming conventions; three test files switch from `.is_empty()` to `.len() == 0` assertions for improved failure message clarity. FeaturesNone identified with supported citations. Tests
FindingsNo active actionable findings. Could not review: crates/tinydocs-bus/src/spec/document/test.rs, crates/tinydocs-bus/src/spec/presentation/test.rs, crates/tinydocs-module/src/outputs/test.rs Before merge

Replace `assert!(x.is_empty())` with `assert_eq!(x.len(), 0)` in test assertions across document, presentation, and output modules to make the expected condition more explicit and consistent with the project's testing style. The vendor submodule is also updated to its latest commit. Auto-committed-on: dragonfly
Reformatted two multi-line assertion chains in the empty reads test to break each method call onto its own line, improving readability without changing any behaviour. Auto-committed-on: dragonfly

This commit edits three legacy test.rs files but leaves both their filenames and the corresponding mod test; declarations unchanged. The newly added repository rule explicitly requires these files to be renamed to <module>_tests.rs with #[path] whenever they are next touched, so this change delivers code that already violates its own migration policy; rename all three touched test modules as part of this commit.

This unrelated gitlink update changes the exact TinyBus source compiled by tinydocs-module and archived by the release workflow, despite this commit being presented as a test-layout documentation change with no runtime behavior changes. Move the dependency bump into a separate commit where the upstream delta and compatibility can be reviewed and validated independently, as required for vendored TinyBus updates.

The target commit's complete tracked-file listing contains no scripts/externalize-inline-tests.mjs (the only tracked script is .github/scripts/check-file-coverage.sh), so contributors following this newly documented command from the repository will always get a missing-file error. Add the helper to this repository or document the concrete external checkout/package required to invoke it.
