V9 evidence is frozen. V9.1 review sync is complete.

This page records the current V9 / V9.1 freeze position: Controlled Pi Testnet Payment Spine passed, V9.1 Safe Negative Backend Validation passed, and public review documentation was synchronized around that evidence baseline.

Core Rule Preserved

No receipt, no evidence, and no access unlock before backend-verified payment state.

Frontend callback alone must never unlock access. Unknown, missing, ambiguous, duplicate, replayed, mismatched, expired, failed, stale, or unavailable states should fail secure.

What This Freeze Does Not Claim

Production readiness is not claimed.
Pi Mainnet settlement is not claimed.
Official Pi partnership is not claimed.
Formal third-party audit is not claimed.
Security certification is not claimed.
Completed commercial pilot is not claimed.
Tamper-proof infrastructure is not claimed.
Independent cryptographic verification is not yet claimed.
All duplicate / replay / failure risks solved is not claimed.

Next After Freeze

The correct next step is controlled review, backend hardening, and public-safe pilot planning.

Duplicate approve behavior.
Duplicate complete behavior.
PaymentId / txid replay behavior.
Mismatch behavior.
Pi API timeout behavior.
Supabase write failure behavior.
Receipt/evidence integrity.
Public verify freshness.
Rate limiting / abuse resistance.
External technical reviewer feedback.
