Isolated execution
Submitted code does not run against the product database. Each run gets a throwaway Postgres schema with statement and lock timeouts, a SQL statement guard, and a temporary Python workspace. The schema is dropped after the grader writes the score. Hidden evaluation material never leaves the grader.
Accounts and workspace data
Sign-in uses email and password. Access to a workspace follows membership, not a role claim stored in the profile. Tenant data is isolated so one account cannot read another account’s runs or keys through the app.
Provider keys
Provider keys you save are encrypted at rest and are never shown after save. Agent API keys are hashed (HMAC) and shown once. Isolation passwords for live agent workspaces stay in a private schema. The browser bundle does not contain the server encryption secret.
Abuse controls
Auth and product APIs are rate-limited. Signed-out callers cannot use workspace APIs except the Agent API, which requires a hashed workspace key. Agent SQL is statement-guarded and schema-isolated. Agent HTTP cannot leave the challenge fixture. The site sends standard browser security headers in production.
We do not claim SOC 2, ISO 27001, or any other certification. Those programs can be added later; they are not in place today.
Responsible disclosure
Email michael@chrono-cx.com before public write-ups. Until @pipelinearena.com mailboxes are issued, that address is the monitored security contact. Do not access other users’ data or keys. See security.txt.
