QSP Stage271: Verifiable External Review Records (Request for Feedback)

[mokkunsuzuki-code]

Hello OpenSSF community,

I am working on a project called QSP (fail-closed session protocol framework),
focused on making verification and trust evaluation reproducible.

Stage271 introduces a concept where external review itself becomes
a verifiable artifact.

Instead of treating review as a trust-only statement,
this stage records review outcomes as:

• structured JSON records
• Ed25519 signatures
• SHA256-linked chain
• CI-based re-verification

---

What is new

Stage270 proves a verification decision (accept/reject).

Stage271 extends this by proving:

• that a review record exists
• which artifact was reviewed
• that it was signed
• that it is linked in a tamper-evident chain
• that it can be re-verified later

In short:

• Stage270 = decision proof
• Stage271 = review proof

Quick verification:

git clone https://github.com/mokkunsuzuki-code/stage271.git
cd stage271
pip install cryptography

python tools/verify_stage271_review_chain.py

Question

I would appreciate feedback on:

Does this approach align with supply-chain security practices?
Is "verifiable review record" a meaningful concept in this space?
Are there similar efforts in OpenSSF / SLSA / provenance work?
Note

This is not a claim of formal peer review or standard compliance.
The goal is to explore making review records auditable and reproducible.

Thank you for your time.

Update:

Stage273 is now completed.

Reviews are now bound to:

• SBOM artifacts (SPDX)
• vulnerability scan results

This makes the review scope explicit and reproducible.
