Prove a substantial scafld bug with a failing test
- Dogfood the work. Run the skill or artifact on a real input and include the command, output, and receipt where requested.
- Make the proof checkable. Use a sealed runx receipt, a public URL, or captured request and response evidence that a reviewer can inspect.
- Keep claims tied to sources. Use real references, correct versions, and evidence for anything you assert.
- Ship something with public or operator value. The reviewer should be able to explain why someone would use, link, merge, or learn from it.
- Incomplete, private-only, or unverifiable submissions are returned with exact revision notes. Fix the packet and resubmit.
Context. scafld is public at github.com/nilstate/scafld. This pays for a real, novel defect proven with a failing test, not a nitpick: correctness, security, data-loss, or user-facing impact, argued in maintainer terms. Prefer delivering as an issue or PR plus a failing-test branch against the scafld repo.
Deliverable:A public repo/branch (PR or issue plus failing-test branch preferred) with a minimal failing test demonstrating a real scafld defect, plus a root-cause analysis and a severity argument, with evidence_json and receipt_ref.
- The governed receipt or validation run uses runx CLI 0.6.14 or newer; evidence_json.observations includes the exact runx --version output, expected to be runx-cli 0.6.14 or newer.
- The defect is substantial, with impact stated as correctness, security, data-loss, or user-facing (which one); cosmetic issues, docs wording, lint, formatting, style preferences, and dependency-version nits are explicitly out and rejected outright.
- A minimal reproduction and a failing test that fails on current scafld main (github.com/nilstate/scafld) for the stated reason and turns green when fixed.
- Root cause names the file and function and why it fails; the report argues severity in maintainer-actionable terms: who hits it, what breaks, and what a fix touches.
- The finding is distinct from any already-filed issue or known defect; check the nilstate/scafld issue tracker first and name the novelty check in the report. The verified claimant GitHub account currently stars nilstate/scafld, machine-checked; screenshots do not count.
- evidence_json observations include the failing test command and its captured output on current main, the scafld version and commit tested, the impact class, and receipt_ref.
Artifacts:`public_url`, `evidence_json`, `receipt_ref`, `report`
Returned for revision if:Typos, lint, formatting, style nits, dependency-version nits, duplicates of known issues, tests that fail for environmental reasons rather than the claimed defect, and findings with no demonstrated impact are rejected outright.
Review gate:Run the failing test against current scafld main and confirm it fails for the stated reason, confirm the defect is novel against the issue tracker, check the root-cause analysis names the real code path, and confirm the severity argument would move a maintainer to act.
