Aggregate eligibility: Eligible version

The task

paramiko's HostKeys matches knownhosts names by literal string equality only: markers, wildcard patterns, bracketed ports, hashed-name writing, certificate trust, and authorizedkeys files are all beyond it. Add a trust-database module paramiko/trustdb.py implementing the OpenSSH formats as documented in sshd(8) (SSHKNOWNHOSTS FILE FORMAT and AUTHORIZEDKEYS FILE FORMAT), sshconfig(5) PATTERNS, and OpenSSH PROTOCOL.ce…

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.

Difficulty, with uncertainty

Selected-best difficulty: 100.0% [56.6%, 100.0%]. This is one minus the best measured current-row pass rate among rows with at least five valid runs.

The maximum is selected from the observed rows, so the estimate is optimistic. Its Wilson interval is not adjusted for model selection. “Hard” requires qualifying GOOD_FAILURE evidence; the threshold flag additionally requires the interval and recorded quality gates to meet the documented rule. This is not independent validation. Threshold flag: no.

Every recorded run

10 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.
