2525 - `.talk-acts` — the row under the last message and last reply holding Edit, Regenerate or Retry; server-drawn, so it works without the script.

2727
28 - Attachments (#8820) — drawn in `src/web/pages/talk.ts` and `talk_client.ts` from the existing `.badge` (a file's name) and `.btn` (Remove, Attach); the only new classes are layout:
29 - `.talk-chips` — the row of chosen files above the box; hidden while empty.
30 - `.talk-files` — the line of file badges under a sent message; each links to the owner-only download.
31 - `.talk-attach` — the "Attach" file-picker label in the composer bar, a `.btn` that stays hidden until the script runs (the picker needs it).
32
2833 Under a reply, `.talk-cost` is one quiet line with the turn's dollars; above the log, `.talk-context` says how full the context is and, from 80 %, suggests a new conversation. Both are `small muted` text, no new colour.

1 # /talk attachments (#8820)
2
3 Attach a file or image to a /talk message: pick it, paste it into the box, or drop it on the composer. It shows as a chip with Remove until the message is sent.
4
5 - **Limits:** PNG, JPEG, GIF or WebP images up to 5 MB; plain text files (txt, md, csv, json, log, code) up to 100 KB, valid UTF-8. Up to 4 per message, 50 MB kept per person. The type is what the bytes are (magic bytes, UTF-8), never the browser's word or the name. Refusals say the limit.
6 - **Stored:** `FORGE_APP_DATA/conversation-files/<user>/<id>`, owner-only, with a row in `conversation_file`. Never in a repository. A chosen file never sent is swept after an hour.
7 - **The agent:** an image is sent to the run as an image block, a text file quoted into the message as data. Only with the message it is attached to: a resume, a steer or a later message is not handed it again. A turn already answering takes text files but not pictures.
8 - **Fetch:** `GET /api/v1/conversation/files/:id`, owner only (another person gets 404), always `attachment`, `nosniff`, a fixed type (an image type or `text/plain`), CSP `sandbox`.
9 - **API:** `POST /api/v1/conversation/files` (raw body, url-encoded `x-file-name`) answers `{id,name,type,size}`; send it with `{"text":…,"files":[id]}` to `/api/v1/conversation/messages`; `DELETE` removes an unsent one.
10 - **Over ssh:** `cat shot.png | ssh <forge> talk --attach shot.png look at this`. The file is the command's standard input (at most 5 MB), named by the word after `--attach`; it is checked and kept like any other and goes with those words. The forge never opens a path of its own, so only what the client pipes in can be sent. One file per command.
11 - **Making room:** past 50 MB the oldest sent files are dropped (their chip under the old message then answers 404); a file waiting for its message is never dropped. Uploads are limited to 20 a minute per person.
12 - **The fence:** a text file is quoted between delimiters drawn fresh for each message, so nothing inside it can close its own quote.
