I4199 — A case that compiles the crate runs alone or caps cargo, so the cases beside it are never starved past their bounds

Cíl

Run 77_rust_evidence alone (its doc-example and benchmark builds take every core), cap cargo at two jobs and two test threads in the two light compiling cases (76_capabilities_projections, 493_mesh_compaction_keeps_what_is_live), and hold the rule with case 4199: a case whose script runs cargo test, bench or build on a manifest declares '# majordomus-exclusive:' or carries CARGO_BUILD_JOBS on that line.

Proč

Train 5 (#2403, d078fb2309e) was red twice on case 431_economics_claims_gated, killed at its 600 s bound (609 s, 608 s). Alone the case takes 51-69 s, its economics code did not change between trains 4 and 5, and the fixture it reads grew 2%. On CI it spent its whole window beside 77_rust_evidence (3434-3905 s of cargo test --doc and cargo bench --no-run) in a shard that runs four cases at a time on a four-core runner. Its time tracked its neighbour, not its own work; raising the bound would hide the starvation.

Aktuální stav

Measured on d078fb2309e: test/run.sh runs '# majordomus-exclusive:' cases alone after the parallel phase and nothing else; 77_rust_evidence, 76_capabilities_projections and 493_mesh_compaction_keeps_what_is_live compile with cargo in the parallel phase, uncapped; no rule ties compiling to either remedy. CI durations: 77 3434-3905 s, 76 171-241 s, 493 6-142 s; 431 on train 5's shard 2 overlapped 77 for its entire 609 s.

Cílový stav

No case compiles the crate in the parallel phase with every core: 77 runs alone and 76 and 493 cap cargo at two jobs, case 4199 refuses any new case that compiles uncapped, and case 431 runs beside light neighbours within its bound.

Závislosti

Žádné. Tento úkol je kořenem grafu.

Kritéria přijetí

• 77_rust_evidence declares '# majordomus-exclusive:' with its reason
• 76 and 493 run their cargo test with CARGO_BUILD_JOBS=2 and RUST_TEST_THREADS=2
• Case 4199 passes on the tree and, on a fixture, flags exactly an uncapped compile while a capped one, an exclusive one and cargo written only as text pass
