The task

The Go module in /app implements DEFLATE compression and decompression. Streams written with flate.NewWriter must be readable by the Go standard library DEFLATE reader, this module's reader, and ordinary tools that enforce the block format. Large highly compressible inputs can produce corrupt output after a writer accepts data and closes successfully. The issue is visible across one-shot and chunked writes and acros…

Excerpt only; not a complete executable task specification. Task ID task_6ccfe02bc1814822 · version 1. Selection status: not fully recorded.

Results by model and effort

This exact task version only. Every rate is passes / valid runs with a Wilson 95% interval; n≤2 remains counts only. Macro aggregation does not apply within a single task. Baselines are summarized in the quality gates, not ranked. A passed no-op resistance check means that doing nothing did not solve the task.

Current evidence

Model / effort	Verifier result [95% Wilson]	Diagnostic labels / valid	HARNESS_ERROR · excluded	Outcome classes

Legacy evidence

Model / effort	Verifier result [95% Wilson]	Diagnostic labels / valid	HARNESS_ERROR · excluded	Outcome classes
GPT-5.5 · default (unverified)	5/5 · 100.0% [56.6%, 100.0%]	0 / 5	0	GOOD_FAILURE: 0 BAD_FAILURE: 0 GOOD_SUCCESS: 0 BAD_SUCCESS: 0

Every recorded run

5 recorded trials, including controls. Diagnostic labels do not replace verifier reward. Labels and quality checks are source declarations, not independently attested here. Internal evidence remains private; a missing public URL is shown explicitly. Records with invalid or absent rewards are not scored.
