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 5	`{"decision": ["caf%C3%A9", "/caf\u00e9", null, true, "a%20b", "{{id}}", false, false, 4, 1], "request": "/requests/5/4"}`	`{"decision": ["caf%C3%A9", "/caf\u00e9", null, true, "a%20b", "{{id}}", false, false, 5, 1], "request": "/requests/5/4"}`	Failed
