Convert single signed proofs into a continuous, tamper-evident audit history.
Stop trusting AI. Start auditing proof history.
Stage322 extends Stage321 by adding a public proof history chain.
Stage321 proved:
Proof JSON → GPG Signature → Public Verification
Stage322 adds:
Proof #1 → Hash #1
Proof #2 → Hash #2 + Previous Hash #1
Proof #3 → Hash #3 + Previous Hash #2
If one record is modified, the entire chain verification fails.
What This Changes
Before:
Single proof
After:
Continuous proof history
This changes REMEDA from an AI proof tool into audit infrastructure.

Security Boundary
This repository intentionally publishes only:
public proof history
public verification UI
public verification script
documentation
This repository must not contain:
private keys
internal core logic
production databases
secrets
private customer data
Private and internal files are excluded by .gitignore.
Verify the Chain
Run:
python3 verify_chain.py
Expected result:
[OK] Proof history chain is valid
Why This Matters
A single signed proof shows that one result was approved.
A proof history chain shows that results evolved over time without hidden tampering.
That is the foundation of auditability.
