// ── Public API version / identity ──────────────────────────────────────────
//
// A tiny, dependency-free descriptor of this backend, surfaced on GET
// /public/status and GET /public/version. A client (notably the Android app)
// uses it to:
//   • positively recognize a Runic Gateway backend on first-run (the `service`
//     tag), instead of guessing from an incidental response shape; and
//   • run a version-mismatch guard — compare `api` against the contract the
//     client was built against and surface a clear "update required" state
//     rather than mis-parsing a future, changed response.
//
// `api` is the coarse contract version (bumped only on a breaking re-shape, which
// would be a v2 mount); `server` is the informational package version.
//
// ── `capabilities` (Phase 14a) ──
//
// Opaque strings naming what CORE serves beyond the surface every backend has —
// the same idea as a module's `capabilities` on GET /public/modules, and
// deliberately the same word, so a client feature-detects one way rather than
// two. They are a different LIST because core is not a module: publishing core
// as a pseudo-module would leave a client unable to tell "this backend has
// events" from "a module called core happens to be installed", which is exactly
// the distinction the loader exists to make.
//
// The value is in what is ABSENT. A backend released before Events answers this
// object with no `capabilities` key at all, so a client can tell an older site
// from one that simply has nothing on its calendar — which it could not do by
// probing /public/events, where "not built" and "temporarily down" look alike.
//
// Static, because these are compiled-in features rather than installed ones:
// a core that has these routes always has them. An unknown string is to be
// treated as absent, exactly as MODULE_API.md §2.1 says of a module's.

const pkg = require('../../package.json')

module.exports = {
  service: 'runic-gateway', // stable backend identifier for first-run detection
  api: 'v1', // API contract version (matches the /api/v1 mount)
  server: pkg.version || '0.0.0', // server package version (informational)
  // What core serves beyond the baseline. See the note above.
  capabilities: ['events'],
