Endpoint atlas

The first-party gateway appears

• `gateway.reddit.com/redditmobile/1/*` shows up for the first time: app config, onboarding, recommendation tabs, push registration. This is a first-party service the public API does not expose.
• `GET /r/{id}/search` adds in-subreddit search.
• Moderation actions arrive: `distinguish`, `marknsfw`, `unmarknsfw`.
• `oauth.reddit.com/api/v1/logout` — the OAuth host is now used for more than token exchange.

OAuth endpoints, gateway paths mirrored

• `GET /api/v1/login` and `GET /api/v1/register` — the OAuth web endpoints, replacing the retired `/api/login`.
• `GET /api/search_reddit_names` for subreddit autocomplete.
• The gateway paths are mirrored under `www.reddit.com/redditmobile/1/*`, which is how they were first recovered.
• No new hosts: the surface grows inside the existing three.

Live threads, gold, user pages

• `live.redditmedia.com/live/{id}/pixel.png` and `www.reddit.com/live/{id}` — Reddit Live threads.
• `/api/v1/gold/gild/{id}` and `/api/register`-era gilding.
• `/api/read_all_messages` becomes the first mutating inbox endpoint.
• `www.reddit.com/u/{id}` — the profile surface moves onto the new path style.

OAuth-first rewrite

• The single largest change in the dataset: 77 first-seen endpoints, more than the other four builds added together.
• Reads now dominate (68 of 113) and mutations collapse to 2 — the client became a consumer of a read-heavy OAuth API rather than a cookie-driven web client.
• Chat arrives wholesale: 20+ `sendbird.reddit.com` and `/api/v1/sendbird/*` paths, plus `channels`, `group_channels` and `down_to_chat`.
• Moderation moves to its own host (`mod.reddit.com`), and the app starts referencing support and marketing hosts (`www.reddithelp.com`, `www.redditinc.com`).
• This is also the only arm64 build, and the only one whose extension image is FairPlay-encrypted — the extension is out of scope, the main executable is not.
