# REMEDA Stage333
Stage329 Audit Submission Package + Stage330 Evidence Hash Auto Builder + Stage331 Execution Integrity + Stage332 Signed Execution Session + Stage333 Transparency Log
Stage333 adds a public transparency log on top of the signed execution session created in Stage332.
This stage records signed execution evidence into an append-only audit history.
---
# What Stage333 Does
Before Stage333:
```text
execution_session.json
↓
signature
Stage333 adds:
execution_session.json
↓
signature
↓
transparency log
↓
previous_hash chain
↓
public audit timeline
This means the execution evidence is no longer just signed.
Its history is also recorded publicly in a tamper-evident chain.
Why This Matters
Normally, audit history can be edited or deleted later.
Stage333 changes this by creating an append-only transparency history.
Each new log entry contains:
timestamp
artifact SHA256
signature information
previous entry hash
This creates a chain.
If someone changes an older record later,
the chain verification breaks.
Simple Explanation
Think of it like this:
Stage332
A teacher signs a test paper.
"This paper is authentic."
Stage333
The signed paper is recorded into a school history book that cannot easily be rewritten.
"When it was signed"
"Which paper it was"
"What came before it"
are all recorded.
Transparency Log
Stage333 introduces:
append-only history
previous_hash chain
public verification timeline
tamper-evident audit history
Public Files
docs/audit/transparency-log.json
docs/audit/timeline.html
docs/audit/verify-transparency-log.txt
Verification
Verify the transparency chain locally:
python3 core/verify_transparency_log.py
Verify the execution session signature:
gpg --verify docs/execution_session.json.sig docs/execution_session.json
Public Timeline

Meaning
Stage332 proved:
"This execution evidence was signed."
Stage333 adds:
"This signed evidence was recorded into a tamper-evident public history."
