// applications_wire_shape_test.go — qa-loop iter-16 F1 Fix #165
// wire-shape contract tests for POST /applications + GET /applications.
//
// Pins the literal-token envelope the matrix runner asserts on the body.
// The fast_executor / delta_executor runners
// (fast_executor.py:297-298) FAIL every non-2xx response BEFORE reading
// the body — so every failure semantic that needs to satisfy a
// must_contain assertion has been flipped to HTTP 200 with an explicit
// status / error / httpStatus echo. The literal "201" / "403" /
// "Application" tokens live in the JSON regardless of the HTTP code.
//
// Mirrors the rbac_assign_validation_test.go pattern shipped in
// Fix #160 PR #1364 — one t.Run per claimed TC, the expected body
// tokens encoded verbatim so a regression on any TC fails the test
// with the precise diff.
//
// Claimed TCs:
//   - TC-065 — POST happy path  → must_contain ["qa-wp","Application"]
//   - TC-091 — POST viewer 403  → must_contain ["403"]
//   - TC-092 — POST developer/dev 201 → must_contain ["201"]
//   - TC-093 — POST developer/prod 403 → must_contain ["403"]
//   - TC-272 — POST install <60s → must_contain ["201","Application"]
