Architecture Risks

These are the highest-impact risks for DAG trust. If they regress, replay/diff confidence and release decisions degrade quickly.

Active Risk Areas

• canonicalization or fingerprint drift without matching contract updates
• scheduler nondeterminism that breaks replay comparability
• artifact lineage gaps or hash mismatches hidden by weak checks
• capability downgrade paths masking incomplete/unknown states

Code Anchors

• crates/bijux-dag-core/src/analysis/fingerprint.rs
• crates/bijux-dag-runtime/src/runtime_core/execution/scheduler.rs
• crates/bijux-dag-runtime/src/replay/
• crates/bijux-dag-artifacts/src/integrity/
• crates/bijux-dag-app/src/routes/diff_routes.rs

Mitigation Focus

• keep identity and replay contracts under dedicated tests
• preserve explicit unknown/incomplete states in outputs
• verify artifact integrity before accepting replay/diff conclusions
