Invalidate redirect mappings by source and affected target with partition isolation: source target direction · case 01

Invalidate redirect mappings by source and affected target with partition isolation: the source target direction branch emits an incorrect decision.

Verified by executionVariant 1 · 7 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The source-target-direction decision uses 'any(e[1]==target for e in entries)'; this violates the stipulated controller policy.

VERIFIED REPAIR

At this decision use 'source==target', preserving the other controller outputs.

Unsuccessful approach: The partial repair uses 'False' and still fails an explicit boundary or control.

Case contract

Invalidate redirect mappings by source and affected target with partition isolation. The explicit fixture inputs and outputs define a bounded offline policy; request identity must accompany the decision.

Why this case matters

Models a redirect controller decision before following a target or exposing a redirect result.

Verification & scope

Stipulated offline redirect policy, not a complete HTTP, browser, URL, cache, or security implementation. Numbered variants vary request correlation identity. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
