Redirect
A Redirect sends a client from one address to another. Its status says whether the move is temporary or permanent.
Another example
After a guide moves, its old address permanently redirects to the exact replacement. Bookmarks and search signals remain useful.

- 01Originating request
- 02Resolution or processing hop
- 03Response, timing, and failure
Use it when
Use redirects for moved resources, main hosts, protocol upgrades, or safe returns after sign-in.
Do not use it when
Avoid chains, loops, home-page fallbacks, and unvalidated external return URLs.

Check contracts and invariants, authorization, and input limits. Test retries, one-time effects, timeouts, and partial failures. Verify data integrity, compatibility, monitoring, recovery, and rollback.
Outcome: Design or review Redirect for this system while keeping data correct, secure, and easy to operate. User context: After a guide moves, its old address permanently redirects to the exact replacement. Bookmarks and search signals remain useful. Technical concept or control: Redirect. Why it fits: Use redirects for moved resources, main hosts, protocol upgrades, or safe returns after sign-in. Do not use it when: Avoid chains, loops, home-page fallbacks, and unvalidated external return URLs. Engineering requirements: Define inputs, outputs, contracts, and rules that must always hold. Set authorization and input checks. Define failures, timeouts, retries, one-time effects, data moves, and compatibility limits. Operations: Add useful signals and logs that hide sensitive data. Set capacity limits and write an operator guide. Test recovery and rollback. Acceptance criteria: Contract and failure-path tests pass. Data and authorization rules still hold during retries and partial failures. Check performance limits, monitoring, recovery, and rollback. Evidence and limits (evidence boundary): The standard covers only the listed scope. It does not choose the visual style, product decision, or Vibulary example. Unknowns to confirm: Where the code runs, data stores, traffic shape, consistency needs, and the security boundary. Also confirm the compatibility period, service goals, and rollback limits.
Check this request
Review the current use of Redirect. Definition: A Redirect sends a client from one address to another. Its status says whether the move is temporary or permanent. Release checks: Check contracts and invariants, authorization, and input limits. Test retries, one-time effects, timeouts, and partial failures. Verify data integrity, compatibility, monitoring, recovery, and rollback. Before changing code, report the evidence you found, gaps, severity, and the smallest safe fix.
