Stage288: Compatibility-Aware Verification URL

Overview

Stage288 provides a public verification URL for a QSP product contract.

This page allows anyone to verify:

• the product contract (Stage286)
• its compatibility guarantee (Stage287)
• its enforced decision (fail-closed)

All through a stable, browser-accessible interface.

---

Key Concept

Stage288 transforms verification from:

local, technical validation

into:

public, accessible verification

with compatibility awareness.

---

What This Stage Shows

The public verification page includes:

• Contract Decision (accept / pending / reject)
• Public Status
• Compatibility Result
• Fail-Closed Enforcement
• Contract Metadata
• SHA-256 Digest
• Compatibility Checks
• Exposure Artifacts

This page is generated deterministically from:

contract artifacts
compatibility results
verification policies
Local Build
python3 tools/build_stage286_product_contract.py
python3 tools/check_stage287_compatibility.py
python3 tools/verify_stage287_compatibility.py
python3 tools/build_stage288_site.py
python3 tools/publish_stage288_site.py
What This Stage Proves
product contracts can be publicly verified
compatibility can be exposed alongside verification
fail-closed enforcement can be externally observed
verification can be accessed without local tools
Why This Matters

A verification URL becomes meaningful only when:

it remains valid across versions
it exposes compatibility
it reflects real execution enforcement

Stage288 satisfies all three.

Future Directions
Verification API (Stage289)
multi-version compatibility layers
signed public verification bundles
external policy integration (OpenSSF)
