A selection mixing a file the server takes with one it refuses dropped the refused one without a word, and the Compose and paste-dialog pickers never toasted even when every file was refused. Every pick, drop and paste filter now goes through one helper that counts what the classifier refused: a partial refusal toasts how many were skipped while the rest upload, a full one keeps the existing Unsupported file type toast, and a clipboard paste that falls back to its text stays quiet.
fix(uploads): refuse an unsupported video before uploading it
Conflict resolved against #621 in src/web/public/image-input.js (the
_promptAttachKind doc comment only): #621's comment is kept with #622's
clause that a video MIME counts only for the containers the server
admits; #622's video MIME check and #621's document branch both stay.

_promptAttachKind returned 'video' for any video/* MIME, so an Android
3gp or an mkv streamed up to 1GB before the ?kind=video route refused it
with a 400. Mirror the server's own video-container set so those are
filtered client-side and get the existing unsupported-file toast at once.
Follows the maintainer's follow-up suggestion on #606.
The Attach button, the Compose and paste-dialog pickers, terminal drop and the
clipboard now take documents beside images and videos: the office formats
pdf/docx/pptx/xlsx/zip and the text family txt/md/csv/tsv/json/log/yaml/yml/xml.
A document is admitted by its name's extension (the MIME a phone attaches to a
.md is anyone's guess), buffered under the same 50MB image cap, and judged on
its bytes by the same fail-closed sniffer: a magic-number signature for the
binary formats, UTF-8 with no NUL byte for text. It is saved under a sanitized
stem of its name, so Q3 report.pdf is findable as paste-<ts>-<hex>-Q3-report.pdf.
sh/py/js/html are refused by name with a clear 400. That is a scope choice, not
a security property: file-raw already serves non-media text inert, so this keeps
the server from storing what it would serve or an agent could run, and html and
svg are the ones deliberately kept out. One client classifier (_promptAttachKind)
now returns image, video or document, and the server's dispatch mirrors it: an
image MIME wins whatever the name says, a document extension takes the document
branch, and a foreign extension with no image MIME is refused only after the
image sniff fails, so nothing the image path accepted by its bytes is lost.
A phone-only toolbar Attach button hands the agent a photo or a video with the
keyboard down. It owns its own file input, positioned over the button so iOS
anchors the picker popover to it; the picked paths land on the prompt as unsent
text, so Compose adopts them together with anything already typed and Use
terminal keyboard hands a single-line draft back the other way.
Videos take a second path on the same route: ?kind=video streams the file to
disk under MAX_PASTE_VIDEO_BYTES (1GB, env CODEMAN_MAX_PASTE_VIDEO_BYTES)
instead of buffering it, sniffs the container from the first bytes as they
arrive, drains a mislabeled body unwritten and unlinks on any failure. It draws
on its own 3/min per-(IP, session) rate bucket beside the image path's 30/min:
at 1GB each, 30/min would be 30GB of disk a minute. Without the flag the route
is byte-identical to the image-only version, same 50MB cap and same bucket.
One client classifier, _promptAttachKind (MIME first, then the name's
extension), drives every pick and paste surface: the Attach button, terminal
drop, the tile grid's drop, the Compose and paste-dialog pickers and the
clipboard handlers. A pick that lands while the tile grid owns the terminal
goes to the PTY rather than the parked main-terminal overlay.
