Sign the CLI in through a browser, and cut in the cloud from it - #213
Conversation
A password typed at the prompt lands in scrollback, and one passed as a flag lands in shell history and in `ps`. `podcli login` now opens a request on podcli.com, prints a short code, and waits for a browser that is already signed in to approve it. No credential is taken here, and the session it comes away with is minted only when the terminal collects it. `podcli process --cloud` hands the episode to the same engine running on the worker rather than to this machine: the recording is uploaded, the render the studio would have queued is queued, and the finished clips come back to the folder a local run would have written. `podcli logout` now ends the session at the server too. Deleting the local file alone left the token live for its full month, so a laptop signed out because it was about to be lost stayed signed in.
A thumbnail is an HTML page photographed by headless Chrome, so the frame is an <img>. A file the browser cannot decode was never an error: the page rendered anyway, the caption box and the logo landed on bg_color, and the command exited 0 with a path to a blank card carrying a 15px broken-image glyph in the corner. On a dark template that is a black rectangle nobody can tell apart from a picture that worked, and every caller downstream stored it as a finished thumbnail. A missing frame was worse, because it also moved the box to the no-photo height. Both are refused now, in the words of what happened, while the answer is still a message about one picture. The file:// URIs are built with as_uri() rather than an f-string: a '#' or a '?' anywhere in the path was a fragment or a query to the browser, so the image silently dropped and the card rendered as bg_color the same way. photo_object_position was asked of the model, exposed in the template editor and then never read; the CSS hardcoded center center. line1_nowrap shipped in the defaults and was documented as tunable while the renderer overwrote it unconditionally. Both now do what they say.

Force Pillow to decode non-SVG frames.
_check_frame() can accept a truncated image because Image.open() may defer pixel decoding. The frame then reaches generate_thumbnail_with_template(), where the browser can render a blank card. Call im.verify(), then reopen the file and call im.load() before accepting it.

Do not report a successful cloud render until required clips are downloaded.
_follow() treats status == "done" as terminal, although the job only reports the clip count. _download_clips() makes one episode-detail request, skips clips whose video is None, and run() returns normally with “Nothing to download yet”; main() exits 0 with no local output. Retry the episode retrieval for a bounded period, then raise CloudRenderError when expected URLs or downloads remain missing.

Validate photo_object_position before rendering.
thumbnail-render accepts an untrusted title, and the AI response is copied into CSS without validation. The Playwright command loads the generated file:// page without network isolation, so an injected url(...) can trigger an outbound request. Allow only valid object-position values and fall back to center center.

Skip the POSIX mode check on Windows.
The Python CI job runs pytest tests/ on windows-latest. st_mode does not represent Windows ACLs. Guard this test with @unittest.skipIf(os.name == "nt", "Unix file modes are not enforced on Windows"), matching tests/test_env_settings.py. Do not add a DACL assertion because the repository defines no Windows DACL contract.

Why
A password typed at the prompt lands in scrollback, and one passed as a flag lands in shell history and in
ps.podcli logintook both.What changed
Browser sign-in.
podcli loginopens a request on podcli.com, prints a short code, and waits for a browser that is already signed in to approve it. No credential is taken at the terminal;--emailand--passwordare gone, and--no-browserprints the link instead of opening it for SSH sessions. Needs the matching podcli-cloud change (/v1/auth/cli).Cloud rendering.
podcli process <video> --cloudhands the episode to the worker instead of this machine: upload (single PUT or multipart with ETags), queue the render the studio would have queued, follow its progress, and download the finished clips into the folder a local run would have written. It branches before any local analysis, so the episode is not transcribed twice.--template-idcuts in a saved cloud template.Only params the worker understands are sent. A local
logo_pathmeans nothing to a machine that cannot see this disk; the workspace template covers it there.Logout. Now calls
/v1/auth/logoutto end the session at the server, and still clears the local file if the server is unreachable. Deleting the file alone left the token live for its full month.Verification
