Review six release claims
Objectives
Six release dossier claims await approval. The manager says every claim mentioning a signature or a security acronym should pass. Evaluate whether each claim supports its stated conclusion, not whether the terminology sounds reassuring.
Accept claims with sufficient scoped evidence. For a rejection choose the most specific reason: origin for resolver trust-boundary errors, binding for missing byte identity, assurance for unsupported build-level claims, or applicability for unsupported exploitability conclusions.
Verdicts are accept or reject. Every rejection needs one reason code from: origin | binding | assurance | applicability.
Release dossier claims
SC-1 | Internal namespace can fall back to a public registry when a public package has the highest version; this prevents dependency confusion. SC-2 | Release SBOM records exact component versions and dependency edges, declares scope, and identifies the deployed artefact by verified digest. SC-3 | A valid artefact signature alone proves this build meets SLSA v1.0 Build L3; no builder isolation evidence is needed. SC-4 | The retained SBOM is associated only with a mutable release label; no digest links it to deployed bytes, but it proves their inventory. SC-5 | A not-affected VEX decision needs no technical justification because the download has a valid signature. SC-6 | A high affected finding is due 168 hours after confirmed detection; closure requires evidence that the corrected version is deployed.
Checks the server runs (3)
- Every line in the fixture carries a verdict
- Accept and reject land on the right lines
- Each rejection cites a valid reason code
Check names are all you see here: the expectations that decide pass or fail, and the reference solution, stay on the server.
Step-by-step hints
The guided walkthrough, in full. It is free: no XP cost, and it does not touch the paid hint ladder or the reveal gate.
- Step 1
Read the request before the artefact
Read each line as an assertion with a specific conclusion. Useful evidence can still be insufficient for that conclusion.
- Step 2
Judge every line, including the boring ones
Account for every dossier line exactly once, including those that already meet the requirements.
Every line in the fixture carries a verdict
- Step 3
Separate what is wrong from what is merely ugly
Compare the claimed protection against the failure it would actually prevent. Avoid treating an authenticity result as a universal safety result.
Accept and reject land on the right lines
- Step 4
Say why, in the vocabulary the programme uses
For rejected claims, map the missing control to the supplied reason definitions rather than choosing a code merely because a word appears in the line.
