 ### Added

 - Firefox cookie extraction (`--firefox-profile`) alongside existing Chrome/env/CLI credential paths.

 - Colorized help banner and example block; `pnpm bird` builds then runs the CLI; no subcommand shows help.
 - JSON5 config files (`~/.config/bird/config.json5`, `./.birdrc.json5`) for defaults like engine and browser profile.
 - Config toggles to disable cookie sources (`allowChrome`, `allowFirefox`) and default transport now `graphql` with Firefox as preferred cookie source.
+- Conversation commands: `thread` and `replies`, plus `search` and `mentions` convenience helpers.
+- Sweetistics transport for all commands (tweet, reply, read, thread, replies, search) with automatic 15s timeouts and media uploads (images or single video).
+- Sweetistics conversation fetch now forces fresh data (`force=true`) to bypass cache for `thread`/`replies`.
+- CI workflow on push/PR (Node 22, pnpm 10, Go stable) running `pnpm test`.
 
 ### Changed
 - Default option resolution now honors config files (project then global) before env/CLI overrides.

-### Changed
 - `whoami` now prefers Sweetistics when an API key is present; otherwise uses Twitter cookies.
+- Sweetistics media uploads use the Sweetistics engine only; GraphQL mode rejects mixed media.
 
 ### Fixed
 - Fallback to scraping the authenticated settings page when Twitter account APIs return 404, so `whoami` still resolves the user.
 - Sweetistics calls now time out after 15s to avoid hanging CLI commands when the API is slow or unresponsive.
 - Sweetistics tweeting now supports media uploads (images or single video) via new CLI `--media/--alt` flags.
+- Coverage raised above 70% via new cookie and conversation tests.
