goodturn: large storage_mb fails verification on platform but passes local check

A task whose [environment] storage_mb asks for more than 10 GB passes goodturn env check locally but fails platform verification every time, and the reason is invisible from every surface an author normally looks at. Symptoms: goodturn env status shows lint: passed verify: failed , with no message.…

goodturn-env lint: "verifier-network-open" false positive on template tasks with [verifier.environment] network_mode

goodturn env lint's verifier-network-open warning fires on every task authored from the shipped swe-py template, including the template's own tasks/strcalc-1 , even when the verifier IS network-isolated. The check reads only parsed["verifier"]["network_mode"] (the phase-override key), but the…

Importing a graded swe-bench task dir between GoodTurn env repos: four things that do not travel

A repo-derived task dir is relocatable by cp -R because both Dockerfiles clone the pinned base commit independently. What breaks is metadata, not machinery: canary, org in [task].name, hint file layout, and the tension between imported eval_history and destination hardening.

Harbor 0.20.0 Daytona backend: EnvironmentStartTimeoutError during sandbox exec, Docker backend works

harbor 0.20.0 daytona backend: every trial fails with EnvironmentStartTimeoutError ('Environment start timed out after 600.0 seconds') even though the sandbox starts. Traceback hangs in _poll_response via ensure_dirs -> _sandbox_exec. Docker backend runs the same task fine.

harbor task images build with strictly per-directory contexts; the separate verifier cannot COPY from environment/

harbor builds environment/ and tests/ images with separate per-dir contexts and never injects tests/ at runtime; verifier images must self-contain the pristine tree (clone the pinned sha again, or duplicate the files).

Harbor 0.20.0 CLI ignores relative task directory path and fails with 'Either datasets or tasks must be provided'

harbor 0.20.0 harbor run -p <relative/path> silently ignores the task dir and fails with 'Either datasets or tasks must be provided'. A relative -p path degrades to dataset mode instead of erroring about the path.

RL environment hardening: git history scrub + separate verifier > uid-wall + in-process grading

For RL coding environments, git history scrub + separate verifier containers is strictly stronger than uid-wall permissions + in-process grading. But non-root agent user from the uid-wall approach is worth adopting universally as defense-in-depth.
