Summary

0.34.0 adds Custom runner Arms for process Experiments, with preflight checks, sandboxed execution and retained Session accounting (#2203).

• New thirdshift evals check-runner <name-or-file.toml> [--suite <suite> --task <task>] [--json] checks runner inputs, credentials and Model pricing, with an optional sandboxed Trial that creates no Experiment record. Available through POST /api/v1/evals/check-runner too (Add evals check-runner, its Console API twin, and Custom runner documentation #2239).
• Add --baseline-runner and --candidate-runner for explicit process suites, freezing manifests and mapped files with provenance. Setup format 13 makes commit/Harness fields nullable; older builds cannot read Custom-runner Experiments (Freeze Custom runner Arms and run process Trials #2194, Spec: Custom-runner Arms for process Experiments #2203).
• Console starts Custom-runner Experiments and shows frozen identities in comparisons and Trial Peek. Pairwise evidence withholds runner attribution until preference submission while preserving ordinary source evidence (Support Custom runner Arms in Console Experiments #2206, Spec: Custom-runner Arms for process Experiments #2203).
• Run Custom runners and their children in one sandbox with declared Harnesses, logins, Trials-only [providers] keys and provider hosts. Panel voting withholds same-family votes. Harden host file handling and bound recorder resources (Enclose Custom runner Trials in declared multi-provider sandboxes #2205, Spec: Custom-runner Arms for process Experiments #2203, Record Custom runner sessions and enforce Trial accounting #2227).
• Retain priced Session traces from record_command or sessions.json for Trial Peek, Waterfall and export. Quota usage at 85% pauses Experiments; web-search evidence voids native and Custom Trials. Missing Session accounting voids valid runner-reported outcomes, while crashes and timeouts remain failed (Record Custom runner sessions and enforce Trial accounting #2227).
• Command log and Session trace pages show GitHub target links and titles locally and across Fleet (Show GitHub target link and title on log reader pages #2240).
• Seal release-summary Sessions from host toolchain roots and skills, binding only the Node executable when required (Seal the release summary sandbox: no toolchain roots or skills, only node #2243).

Site and docs: document Custom runners and preflight checks, update site pages and the generated manual, and deduplicate release Pass-skip guidance (#2239, #2244).
