Case contract

Expand redirect templates with context-specific escaping and missing-variable policy. 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.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
fixture 7	`{"decision": ["%2Fa%2F%2Fb", "/{other}//a//b", "x", false, "a%2Fb", "literal", false, false, 5, 1], "request": "/requests/3/6"}`	`{"decision": ["%2Fa%2F%2Fb", "/{other}//a//b", "x", false, "a%2Fb", "literal", true, false, 5, 1], "request": "/requests/3/6"}`	Failed
