Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughModule-local tests now load from sibling files, and AGENTS.md documents the naming and declaration rules.

Priority: ⬇️ Low Estimated code review effort: 3 (Moderate) | ~25 minutes Change: Other Merge Risk: 🔵 Low · up to The change mostly reorganizes tests and has no known runtime impact. Before merging, add the missing module-level descriptions to the extracted test files and consider adding a test for the unavailable-module path in the updated TinyBus. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Most changes reorganize tests or preserve existing behavior. However, the updated TinyBus revision participates in module admission and confidential signing. Its implementation was unavailable for comparison, so preservation of those controls and lifecycle guarantees remains unverified. No new security bypass was established. Retained concerns

The filename is derived from the old child-module name test, so btc.rs points to btc_test_tests.rs; the other five extracted modules use the same duplicated suffix. These are the first test groups for their implementation modules, so the repository convention requires btc_tests.rs, rlp_tests.rs, and analogous names rather than the topic-group form. Rename the files and update each #[path].

Every newly extracted test file starts with an inner lint allowance and then a selective use super::{...}, rather than the required use super::*;. This makes all six files violate the standardized test-file layout introduced by this commit; move the lint allowance to the module declaration if needed and use the mandated parent import.

None of the six new *_tests.rs files begins with a //! module description; each starts directly with a lint attribute. Add a concise module-level description to every extracted test file so the newly documented repository convention is satisfied.

Replace all uses of `.is_empty()` in test assertions with explicit `.len() == 0` or `.len() != 0` comparisons for consistency and to avoid potential ambiguity with boolean coercion. Auto-committed-on: dragonfly
Reformatted three assert_eq! calls in the Tron test file to improve readability by removing inconsistent spacing around the rig.transport calls and breaking long lines across multiple lines for better code style consistency. Auto-committed-on: dragonfly
Add tests covering overflow scenarios in Bitcoin coin selection and transfer, invalid recipient addresses, malformed keys and signatures, and a recovery id outside one byte in Tron signing. Extract the recovery id narrowing into a helper function to improve testability. Auto-committed-on: dragonfly
The overflow test was using u64::MAX and 1 as utxo values, which caused an actual overflow rather than testing the invalid field error. The values are now split into two halves that sum to u64::MAX without overflowing. The invalid signature test was using zero bytes which could be misinterpreted; using 0xff ensures the signature is clearly invalid. Auto-committed-on: dragonfly

The module crate compiles TinyBus directly from this path, so advancing the gitlink from df6f990 to dc8c92f changes a production dependency in a commit described as test-only. Keep the parent revision here and submit the dependency update separately so its upstream changes and validation can be reviewed independently.

This assertion edit touches a pre-existing test.rs, as do the analogous edits in eight other legacy test files in this commit. The newly added migration rule expressly requires each such file to be renamed to <module>_tests.rs and wired with #[path] the next time it is touched; the earlier review comment covers the newly extracted files, whereas these modified legacy files remain unmigrated.

Test the unavailable-module call path.
The TinyBus Broker::route now returns an error when a method call targets a named module and unavailable_for reports it unavailable. The wallet e2e test waits until BUS_NAME is serving before calling the proxy, so it does not exercise this branch. Add a test that calls the proxy while the target is unavailable and asserts that the call returns an error.

Review comment at @vendor/tinybus at line 1:
Add a wallet e2e test that calls the proxy for BUS_NAME before the target module
is serving, then assert the call returns an error. Keep the existing
serving-path test intact so the unavailable-module branch in Broker::route is
explicitly exercised.

Summary
Moves the inline
#[cfg(test)] modblocks into 6 sibling<module>_tests.rsfiles, each declared with#[cfg(test)]+#[path]abovemod tests;, and records the rule inCLAUDE.md/AGENTS.md. The moves are mechanical: bodies are copied verbatim (dedented, rustfmt'd) and the module keeps its place in the tree, souse super::*, privacy and relative paths are unchanged. Produced with OpenHuman'sscripts/externalize-inline-tests.mjs.Related issue
None.
API or behavior changes
