> ## Agent Instructions
> To build and serve your own model, start at /deploy/development/quickstart and /deploy/development/overview. Deploying is the default path: reactor init scaffolds a workspace, reactor auth login authenticates, and reactor model deploy registers the model, publishes the release with the weights/ folder, and activates it on Reactor's GPUs, in one command from that workspace. Docker must be running, because the publish step builds the image locally. Bump model.version in reactor.yaml before redeploying a change, because a release that already has an image is reactivated as it is. Deployment access is granted per account, so contact team@reactor.inc if a deploy is refused. Every key in reactor.yaml is documented at /deploy/platform/reactor-yaml. Model code imports reactor_runtime; Python client code imports reactor_sdk. The runtime overview explains the model interface. Running the model on your own machine with reactor run is optional and needs a GPU you attach with --gpus; /deploy/development/local-testing covers that loop and pairs a complete brightness model with a Python client test in a separate brightness-test workspace.
> Reactor hosts multiple models, each with its own connect slug (modelName) and command/event schema. The video model catalog — slug, typed SDK package, and links to its schema — is at /model-api-reference/overview. Robotics policy documentation starts at /robotics/overview; The launch policies are Cosmos Nano DROID (/robotics/cosmos/nano-policy-droid/), DreamZero DROID (/robotics/dreamzero/droid/), and FLUX Action DROID (/robotics/flux-action/droid/), organized by model family and embodiment. Some models expose one slug per experience (e.g. HappyOyster); always take the slug from the model's own pages, never guess it.
> Fastest path to a working app: `npx create-reactor-app my-app --model=<slug>` scaffolds a complete app with secure auth wired up. Typed TypeScript SDKs are published as @reactor-models/<model>; Python uses the base reactor-sdk package.
> Auth: exchange an API key (rk_...) for a JWT via POST https://api.reactor.inc/tokens from your server. Never put the API key in client-side code.
> Append .md to any docs URL for clean Markdown. Search these docs via the MCP server at https://docs.reactor.inc/mcp.

# Get a recording playlist

> Returns an HLS VOD playlist (`.m3u8`) for a recorded session. Each segment URL is
presigned and fetched directly from storage. A session is recorded when its model turns
recording on (`runtime.recording` in its `reactor.yaml`); for any other session the answer
is `404`.

`start` and `end` select a window in seconds. Without `start`, the playlist begins at the
start of the recording; without `end`, it runs to the last uploaded segment. One request
returns at most 10,000 segments, so a longer window is shortened rather than refused. A
segment that could not be recorded appears as an `#EXT-X-GAP` entry, so the timeline
stays intact.

While the session runs, a window the recording has not reached yet answers `202`. The
recording advances with the model's output, not with time. About 15 minutes after the
session closes, the same request answers `200` or `410`, so polling always ends.

Callable by a `developer`, `account_admin`, or `user` of the account that ran the session
or of the account that owns the model; `billing_admin` is not allowed. A session token
reads only the sessions bound to it, open or closed. Bind a session before it ends, or
read with an API key.
