# `includes/rest/` — REST route map

Discoverability index for the REST surface. Routes are still registered in their owning subsystem files (where the callback closures and module state live), so moving the `register_rest_route()` calls into a single directory would have been a paperwork rename that broke nothing and improved nothing. This document is the central grep target instead.

Plugin authors looking for the canonical route URL → handler map start here; the implementation file is one open away.

## Namespace

All in-tree routes register under `desktop-mode/v1`. Extensions are expected to register under `os-<extension>/v1` (declared via the `extensions/base/OpenStation_Extension_Rest` base's `namespace()` method; the base does not enforce a particular namespace — its docblock also permits `desktop-mode/v1`).

| `/agents/{id}/invoke` | POST | `includes/agents/rest.php` | `edit_posts` (filterable via `openstation_agents_user_can_invoke`), then the per-agent gate `openstation_agent_user_can_invoke_agent()` (honours the trigger's `capability`) + per-invoker and per-agent rate limits. The run itself is ceilinged at the caller's own capabilities — see [`docs/agents-security.md`](../../docs/agents-security.md) |

| `/agents/roles` | GET | `includes/agents/rest.php` | `edit_users` (filterable) |

## Conventions

- **Nonce.** Every state-changing route requires `X-WP-Nonce` (the standard REST nonce). Read routes that depend on per-user state also require it.
- **Permission.** Permission callbacks use either `is_user_logged_in()` + capability checks or domain predicates. Shell-internal endpoints that only touch the caller's own per-user desktop state (`/session`, `/default-window`, `/intros`, `/os-settings`, `/pwa-state`, `/presence`) share the `openstation_rest_require_enabled()` gate (`includes/helpers.php`): logged-in **and** `openstation_is_enabled()`, returning `401` when logged out and `403` when OpenStation is off. `read` alone is deliberately not enough — every authenticated role carries it. Filtering with `openstation_*` hooks lets plugins extend or harden access.
- **Errors.** Failures return `WP_Error` with a stable `code`, a translated `message`, and a `data: { status: <int> }` block. Codes are documented per-endpoint in `docs/hooks-reference.md`.

## Why no central registration

PHP `register_rest_route()` calls execute on `rest_api_init`. The callback closures in the existing files capture per-module state — the recycle-bin store, the desktop-files registry, the AI provider — that lives in the same module. Moving the registration calls out of those files would force every callback to re-look-up its dependencies, increasing surface area without reducing coupling. The route → handler-file map above is the discoverability win we wanted; the per-module registrations are the layout that minimises blast radius.

If a future extension adds REST routes that don't fit any existing module, the `extensions/base/OpenStation_Extension_Rest` base class is the cheapest path. See `extensions/base/README.md`.
