/*
 * Ably Platform Auth REST API
 *
 * The subset of the Ably **platform** REST API used for authentication and token lifecycle: requesting Ably Tokens, revoking them, and reading server time. This is a *separate* API from the Ably Chat REST API (`openapi/ably-chat-rest.yaml`, path prefix `/chat/v4`) — token issuance and revocation live on the platform host under `/keys/...`, not under `/chat/_*`.  ## Scope & provenance Ably publishes an authoritative platform spec, [`ably/open-specs`](https://github.com/ably/open-specs) `platform-v1.yaml`, which covers the full generic pub/sub REST API (`/channels`, `/push`, `/keys`, `/stats`, `/time`). **This document is deliberately narrow**: it models only the endpoints this project's authentication story ([ADR-0012](../docs/adr/0012-token-issuance-permissions.md), [SPEC §13](../docs/SPEC.md)) touches — `POST /keys/{keyName}/requestToken`, `POST /keys/{keyName}/revokeTokens`, and `GET /time`. Field-level details are cross-checked against `platform-v1.yaml`, the Ably auth docs, and the `ably-js` auth implementation (see [`../docs/research/2026-07-24-ably-chat-auth-permissions.md`](../docs/research/2026-07-24-ably-chat-auth-permissions.md)).  ## Relationship to the Chat client `ably-chat-rs` is a Chat REST client; it does not itself sign TokenRequests or call `/keys/...` (ADR-0012 Tier 4). This spec documents the platform endpoints a *token server* (or the official `ably` crate) uses to mint the Bearer credentials that are then handed to the Chat client. Capability documents carried by these tokens are described in SPEC §13, not here.
