// /api/offscale/* — auth, then forward to officer-offscale. No routes of its own and no Headscale
// knowledge: this file must never grow app logic.
//
// The sidecar exposes only Officer-owned routes under `/_officer/` — Headscale's REST shape differs
// across releases, and version handling belongs in the sidecar. It holds the admin API key; the platform
// does not know any Headscale URL.
//
// ── The prefix is DERIVED, not written ──
//
// It was the literal '/api/offscale'. That is wrong in a way that only shows up for someone else's
// plugin: the proxy strips `prefix.length` characters to build the sidecar path, so a hardcoded
// '/api/offscale' (13 chars) is correct only because `mountPrefix` happens to return `/offscale` for a
// first-party publisher. The same plugin published by anyone else mounts at
// `/api/p/<publisher>/offscale` and would forward `/alice/offscale/nodes` to a sidecar expecting
// `/nodes`.
//
// `mountPrefix` is the ONE function allowed to know about provenance, so the prefix comes from it. A
// literal here is that rule being broken quietly, which is how first-party and third-party become two
// systems with only one of them tested. Carried over from music, which hit this first.
//
// `appName` is a literal because this file cannot see its own directory name — the platform imports
// `router.ts` and reads `router`, so there is nowhere to inject it. Same known gap music records.
