REMEDA Stage338

Behavior Decision Engine

Overview

Expected Behavior ↓ Actual Behavior ↓ PASS / FAIL / UNKNOWN ↓ behavior_decision.json

Stage338 extends Stage337 by adding behavior verification.

Stage338 adds the Behavior Decision Engine on top of the Stage337 Safe Reproduction Template Library.

Expected Behavior ↓ Actual Behavior ↓ PASS / FAIL / UNKNOWN ↓ behavior_decision.json

This stage introduces behavior verification while preserving all Stage329–Stage337 capabilities.

This stage does not include attack code, dangerous prompts, exploit payloads, bypass steps, or automated attack logic.

What Stage338 Adds

• Behavior decision JSON
• Expected behavior
• Actual behavior
• Pass condition
• Fail condition
• PASS / FAIL / UNKNOWN decision
• SHA256 binding for actual behavior

Safety Policy

Stage338 explicitly excludes:

• Attack code
• Dangerous prompts
• Bypass procedures
• Exploit payloads
• Automated attack logic

Public Files

• docs/templates/safe_reproduction_templates.json
• docs/index.html

Private Files

The following are intentionally excluded from GitHub:

• core/
• local/
• private/
• .env
• secret keys

Meaning

Stage336 answers:

What is happening in the world?

Stage337 answers:

How can we safely define a check?

Next Stage

Stage339 can bind behavior decisions into a verification session.

Stage338: Behavior Decision Engine

Stage338 extends Stage337 by adding a behavior decision layer.

Stage337 created the safe reproduction template rulebook.

Stage338 compares:

• Expected Behavior
• Actual Behavior
• Pass Condition
• Fail Condition

and outputs:

• pass
• fail
• unknown

The public result is saved as:

docs/behavior/behavior_decision.json
What Stage338 Adds

Stage328 checked whether evidence matched.

Stage338 checks whether behavior is correct.

This is a different layer.

Stage338 does not include:

attack code
dangerous prompts
exploit payloads
automatic attack logic

It only performs safe behavior decision based on public-safe metadata and observed behavior.

Meaning

Stage338 moves REMEDA/QSP from evidence verification toward behavior verification.

This connects to future verification of:

SBOM behavior consistency
SLSA build behavior
QKD key exchange behavior
PQC signature verification behavior
