Two runs of one history recorded different traces at observation 4 (`incremental`). It passed on one run and failed on another for the same commit (4bc4eb1, PR #90). It also failed on main (4d3c8a9) before the stream-order fix, at observation 0 (`cli`).\n\nPR #90 excludes it from PR CI until this is fixed, so the determinism job is not red at random.\n\n## Replay\n\n    cd packages/oracles && pnpm exec vitest --run --config oracle-gaps/vitest.config.mjs gap-report-oracle -t \"determinism: constructed history: a daemon pause that cannot engage\"\n\nThe failure message prints the history and the first 2,000 characters of each run's trace. For the full texts, a scratch patch to `src/oracle-property.ts` that prints them was needed (see #81).\n\n## Authority\n\nRegister (2026-11-14, determinism under load): an oracle driver must not rely on wall-clock ordering. A daemon pause that depends on timing is that kind of dependency.\n","author":{"url":"https://github.com/KyleAMathews","@type":"Person","name":"KyleAMathews"},"datePublished":"2026-11-15T09:48:50Z","url":"https://github.com/TanStack/oracles/issues/105"}
