- Harness selection uses Cargo dep-info and reachable-code narrowing (`tools/parity_reach.py`).
`horizon-client-lib` builds the control tool and client probes without gameplay; their dep-info
excludes `game.rs` and `game/`, so gameplay edits do not rebuild or select those probes.
Source paths remain in `crates/horizon-client/`. Measure actual harness selection on refreshed
records with `tools/parity.py --changed-files paths.txt --list`; historical counts are not a guarantee.

Gameplay keeps its `horizon_client::<module>` imports through a self-crate alias. The executable
contains only the allocator, mod API marker and a call to `entry::main`. For unit tests, the lib
excludes `entry` and `game`, and the executable test target owns `game` so its process-wide test
state stays separate from the library tests. This compiles gameplay twice for executable tests.
