Regression Targets

Migrated from: obs_vault

Parent: ./Risk Map.md

This note lists the behavior worth protecting with future tests.

Important Regressions

• illegal room transitions
• thin diagonal blocker rejection
• stale-cache startup reuse
• connector rendering on multi-floor routes
• keyboard controls actually wire into the shell startup path
• theme controller teardown removes listeners
• theme map application never hides building-shell
• offline app-assets basemap remains local unless remote is explicitly allowed
• offline static style stays in parity with dynamic style generation
• layer-manager theme reapply updates doors and fast wall line layers
• search selection moves to the intended floor and source type
• offline package opens with routing assets present, not just a valid zip
• visibility filters never blank the building accidentally
• bootstrap debug imports can recover after an initial failure

Mapped Notes

• illegal room transitions -> ./Wrong Door Risk.md
• thin diagonal blocker rejection -> ./Cross Wall Risk.md
• stale-cache startup reuse -> ../decisions/Caching Strategy.md
• connector rendering on multi-floor routes -> ../modules/Pathfinding.md and ../modules/Path Renderer.md
• keyboard controls -> ./Shell Bootstrap Risks.md
• theme teardown -> ./Theme Controller Risks.md
• theme controller cleanup -> ./Theme Controller Listener Cleanup.md
• broad map layer matching -> ./Broad Map Layer ID Matching.md
• host style resolution -> ./Host Mode Style Resolution.md
• offline basemap drift -> ./Offline Basemap Theme Drift.md
• layer theme reapply -> ./LayerManager Theme Reapply State.md
• search selection -> ./Search and Selection Risks.md
• offline package routing assets -> ./Offline Packaging Risks.md and ./Offline Packaging Risks.md
• visibility filter drift -> ./Layer Visibility Risks.md
• debug import recovery -> ../observability/Observability Risks.md

Why These Matter

• These regressions cover the boundary between geometry correctness, graph correctness, and visible route output.
