Adds a Rust/Actix Web/Diesel example for operator-scoped redirect links. Operators create canonical globally unique slugs, page their links and disable them by revision; public GET/HEAD returns a temporary no-store redirect only for enabled, unexpired links. Destinations are parsed and stored without being fetched.
Account-row locking keeps the cap counter and insert in one synchronous Diesel transaction. Pool checkout and the full operation run inside web::block; an owned admission permit stays in the blocking closure after waiter cancellation. Explicit owner migrations, restricted runtime grants, libpq verify-full, exact dependency pins and bounded input/page/pool limits are documented, including the shared-role trust boundary and absence of creation replay keys.
Validation on native Ubuntu 24.04 ARM64: locked Rust 1.99.0 build, formatter, Clippy, 3 unit tests and separate compiled HTTP/SIGTERM preflight. Eleven distinct real ClickHouse Managed Postgres checks passed across native cancellation and targeted HTTP runs: canonical/owner behavior, independent held-lock contention and cap, second-write and deferred COMMIT rollback, numeric paging including INT64_MAX, expiry/disable, grants/constraints, certificate-specific TLS negatives with positive control, and exact saved-state restart. Empty-schema migration plus repeated migration/seed followed the documented roles. Earlier harness attempts and corrections are retained locally. CI uses no Cloud secrets; the owned test service was deleted and its absence verified.
