submit_proof
shallowio.github.fetchsandbox/mcp · Verify this server
Receipts are readable by anyone with the link — do not attach bodies the user would not paste into a public PR. Attach REAL before/after evidence from the USER's actual app to the run receipt. Use this AFTER you've fixed the bug and re-run the app: it makes the receipt show their own code's behavior (before your fix vs after), which is far stronger proof than a reference simulation. Provide one `proofs` entry per probe you fired — the request you sent, the response BEFORE the fix (bug reproduces), and the response AFTER the fix (bug gone) — keyed to the run's sandbox_id + flow_run_id (from run_workflow's result). This is SELF-REPORTED evidence: it's shown on the receipt but never counts as a proven (green) result. For a MEASURED green proof — FetchSandbox reproduces the bug on your real code and verifies your fix flips it — use `prove_fix` instead.
