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

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

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

ROOT CAUSE

The source-partition-conjunction decision uses '[e for e in entries if e[0]!=source]'; this violates the stipulated controller policy.

VERIFIED REPAIR

At this decision use '[e for e in entries if not(e[0]==source and e[2]==partition)]', preserving the other controller outputs.

Unsuccessful approach: The partial repair uses '[e for e in entries if e[0]!=source and e[2]!=partition]' 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.
