Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The refactor introduces new unsafe code without the repository-required safety justification and allowlist update, so the PR is not merge-ready until that documentation and approval requirement is addressed.

…bal static `SORT_STATS` was a process-global `AtomicBool` gating the `stat!` diagnostics macro. Because fgumi-sort is a library, two sorts in one process with different --sort-stats settings clobbered each other's flag, and the two flag tests had to be serialized with a mutex to survive plain `cargo test`'s thread-per-test model. Hang the flag off the sort's own state instead of a global. `sort_stats` is now a field on `RawExternalSorter` (the sort-options struct, set via a `.sort_stats(bool)` builder from the CLI) and is copied into the `SortPhaseTimer` and `SortWorkerPool` that sorter builds -- the two objects the `stat!` emitters already hold as `self`/`pool`. The macro takes the flag as its first argument (`stat!(sort_stats, ...)`); each emitter reads it from `self.sort_stats` / `pool.sort_stats()`, or takes a `sort_stats: bool` parameter where it is a free function. The global static, its `set_sort_stats`/`sort_stats_enabled` functions, and the `SORT_STATS_LOCK` test mutex are removed; the flag test is rewritten to check the run-scoped default and builder. This removes both the library-concurrency hazard (concurrent sorts now keep independent settings) and the plain-`cargo test` race. Verified end-to-end: `fgumi sort --sort-stats` still emits the phase-timing diagnostics and a plain sort emits none. Closes #849.

Summary
SORT_STATSwas a process-globalAtomicBoolgating thestat!diagnostics macro. Because fgumi-sort is a library, two sorts in one process with different--sort-statssettings clobbered each other's flag, and the two flag tests had to be serialized with a mutex to survive plaincargo test's thread-per-test model.What changed
The flag now hangs off the sort's own state instead of a global.
sort_statsis a field onRawExternalSorter(the sort-options struct, set via a.sort_stats(bool)builder from the CLI) and is copied into theSortPhaseTimerandSortWorkerPoolthat sorter builds — the two objects thestat!emitters already hold asself/pool. The macro takes the flag as its first argument (stat!(sort_stats, ...)); each emitter reads it fromself.sort_stats/pool.sort_stats(), or takes asort_stats: boolparameter where it is a free function. The global static, itsset_sort_stats/sort_stats_enabledfunctions, and theSORT_STATS_LOCKtest mutex are removed; the flag test is rewritten to check the run-scoped default and builder.This removes both the library-concurrency hazard (concurrent sorts now keep independent settings) and the plain-
cargo testrace. Verified end-to-end:fgumi sort --sort-statsstill emits the phase-timing diagnostics and a plain sort emits none. Full suite, clippy, and fmt pass.Closes #849.
Risk: Sort diagnostics change when
--sort-statsis enabled; grouping, consensus, sort order, corrected UMIs, and metrics output are none;unsafechanges and CLAUDE.md allowlist updates are none; memory bounds, queue capacity, and thread/backpressure policy changes are none.Fix: Scope
sort_statsto eachRawExternalSorterrun instead of process-global state. Propagate the setting throughSortPhaseTimerandSortWorkerPool, remove the global state and test mutex, and add builder and end-to-end tests for enabled and default-disabled diagnostics.
