Current cross-harness integration-failure profile

Verdict: 4/4 receipts verified; 0 valid comparable task outcomes. This is an integration-failure profile, not market performance and not a quality ranking.

Codex direct and Flywheel on Codex received byte-identical task prompts and byte-identical role-neutral runtime contexts for each task. The four durations below are diagnostic only because no attempt completed with an oracle pass.

Exact outcomes for all four attempts.
Route and task	Duration	Execution	Oracle	Receipt	Exact result
Codex direct agt-001-index-fallback-integrity	35,357 ms	returned	fail	verified	Admitted artifact. Oracle rejected failure_classes_mismatch: the provider emitted degraded_match; the fixture contract requires degraded_match_behavior.
Codex direct agt-003-codex-flywheel-shared-task	5,664 ms	internal_error	not_run	verified	Codex turn failed after one successful staged-file discovery command. The models cache could not load because base_instructions was missing at line 97 column 5.
Flywheel on Codex agt-001-index-fallback-integrity	2,028 ms	malformed	not_run	verified	Inner Codex emitted turn.failed. Flywheel recorded final agent message missing and preserved its ledger entry and verified checkpoint.
Flywheel on Codex agt-003-codex-flywheel-shared-task	2,043 ms	malformed	not_run	verified	Inner Codex emitted turn.failed. Flywheel recorded final agent message missing and preserved its ledger entry and verified checkpoint.

Byte-identical prompt and context parity

Hashes and byte counts match across the two routes for each task.

Limitations

One repetition per cell is an admission pilot, not a performance distribution.
No attempt completed with an oracle pass, so latency is diagnostic only and must not be ranked as speed.
Usage, cost, CPU, memory, GPU, and energy observations are unavailable.
Model identity is requested but not provider-observed.
Claude Code, OpenCode, Aider, and local model routes are not measured in this pilot.
Raw run artifacts remain operator-local; the public record exposes sanitized outcomes and immutable hashes only.

What this does not prove: This integration-failure profile does not establish market performance, a quality ranking, speed, production reliability, harness attribution, or provider-observed model identity.
