    // type-resolve the whole export surface inside a test case no longer do:
    // #4796 lifted that resolution into the `export-origins/` build-time
    // baseline and the pins now compare against it. This value is what remains
    // of the two stop-the-bleed laps (#4850 → 60s, #4864 → 30s) that kept those
    // cases off vitest's 5000ms default while they still compiled.

    // Keep it. Two `createProgram` cases survive deliberately —
    // `data/driver.test.ts` and `ui/app.test.ts` assert TYPE WRITABILITY of
    // retired keys, which is a different fact from export origin and which no
    // export-surface baseline can carry — and the headroom is what stops them
    // riding the same timeout line the export-surface family used to. The value
    // itself is left exactly where the stop-bleed put it — lowering it is a
    // separate decision, with its own measurement, and not this change's to make.
