`scripts/audit_source_lines.sh` (a CI gate) flagged `tests/commands.rs`
(527) and `tests/splits.rs` (524) over the 500-line ceiling. Both are
flat lists of independent `#[test]` fns with no shared helpers, so each
splits cleanly into a sibling integration-test binary (the crate already
uses a topical file-per-concern layout under `tests/`).
- commands.rs (29 tests) -> commands.rs (20: tab/space/profile/search)
+ command_pages.rs (9: internal-page-opening commands). 527 -> 389.
- splits.rs (25 tests) -> splits.rs (13: layout/axis/detach mechanics)
+ saved_split_lifecycle.rs (12: close/archive/restore/group). 524 -> 266.
No tests added or removed; each new file carries only the imports it
uses. `cargo clippy -p ely_browser_core --tests -- -D warnings` clean;
all ely_browser_core tests pass.
