Files, open beside the conversation
A third side panel, built the way the terminal is and filled the way the inspector is: tabs holding open files. Project files over SFTP in an agent chat; notes, skills, knowledge documents, this chat's text attachments and its own scratch document everywhere. Read with pygments, edited in a plain textarea, saved with a conflict check. A bug found on the way in, and the reason this needed its own read path. `ssh.read_file` ends in `clean_output`, which strips ANSI escapes and decodes with errors="replace" -- right for the output of a command, and fatal for an editor: open a file containing an escape byte, press Save, and you have silently rewritten it with the escapes gone and every undecodable byte replaced by U+FFFD. `read_text`/`write_text` decode strictly, report binary rather than mangling it, carry an mtime:size token for a file that moved underneath, and refuse an oversize write rather than truncating -- `write_file` truncates because a model is told how many bytes it wrote, and somebody pressing Save is not. The model-facing pair is untouched: what it returns is a contract a model has been shown. A truncated read opens read-only for the mirror-image reason. Six sources go through one dispatch table, for the reason tool_labels.py is a table: six independently written permission checks is how one ends up written slightly differently, and that failure looks like editing somebody else's note. A save on a project file bypasses agent/policy.py, which makes it the fourth documented exception to "the modes do not govern the keyboard" and the first that writes. Same argument as the terminal panel -- whoever owns the credential could write the file with scp -- but the consequence is larger and is now said out loud rather than left to be inferred. The model opens tabs from the file tools it was already calling, so no new schema and no tokens. It never brings one to the front: an agent reads forty files in a long reply, and taking the screen each time would drag somebody through all of them and lose any edit in progress. Only the strip is streamed, guarded on truthiness so the frame can never blank itself -- an empty one would close every open tab, the approval card you could press twice with the sign reversed. Both halves are settled on the server, which is why canvas.js needs no guard against a swap at all. No vendored editor. CodeMirror 6 needs a bundler, which is hard rule 1; CodeMirror 5 would be a larger payload than xterm on every page, and xterm is the one heavy dependency precisely because it loads only where it can be used. So: server-rendered highlighting for reading, a textarea for writing, and the panel says there is no colour while you type rather than pretending. Also here: a scratch document per chat, with `scratch_write` at RISK_READ on plan_update's argument, and a test pinning the three numbers that decide a panel's width -- LAYOUT_BOUNDS drops an unknown variable silently, so a panel missing from it has a drag handle that works and forgets. Driven under a DOM stub and against the running application. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

A directory the model knows about, and @ to name a file in it
An agent chat used to open with the model knowing the name of a machine and nothing about what was on it, so the first two rounds of every reply went on finding out. It now gets a listing: one read-only command, `git ls-files` where that works and `find` otherwise, falling back to an SFTP walk that always does. git first because a repository already carries somebody's considered list of what is not part of the project, and reproducing it by hand is how an index ends up mostly build output. The listing is budgeted rather than dumped. A tree of a thousand files is worse than no tree -- it costs the window on every request forever and buries the four names that mattered -- so directories that will not fit are shown as a count and the model is told to open one itself. Collapsing picks the deepest and largest first: by saving alone it would take `src/` before `src/web/static/vendor/`, because it contains it, and lose every name worth having. Read from a cache and never fetched. `harness.context_variables` is synchronous and sits on the request path; the walk happens in the generation setup, which is async and already doing network work, with a short wait. A chat whose first reply outruns its first walk simply has no listing that turn and the fragment disappears rather than appearing as an empty heading. Then `@`, over the same index and over the library, and `/` for commands with an Alt-based keyboard for the same jobs. A mentioned file arrives as contents, not a reference -- a small model asked to call file_read often does not bother -- and it arrives with its absolute path and the machine it came from, because a model handed `main.py` cannot tell which of four it is and cannot name it back when asked to change something. The rule that matters for `/`: a message that merely starts with a slash still sends. `//` escapes and an unrecognised command is posted as written. Swallowing somebody's message is a much worse failure than an unknown command. Two exceptions to Manual mode now, not one. Browsing and indexing are a person acting, not a model, so neither passes through policy.py -- the same argument the terminal panel rests on.

The composer decides what a chat is, and the topbar stops trying
The mode select in the topbar posted with hx-post against a route that only answers PATCH, so every change returned 405 and the mode never moved. htmx shows nothing when a request fails, so the control looked like it worked: the select stayed where you put it and the server ignored you. It has never worked. Two more of the same kind. A mode could not be chosen at all until the chat existed, so reaching Plan meant sending something in Manual first and letting the model answer under the wrong rules. And the project directory box was real and submitted, but unlabelled and squeezed to a few characters by the select beside it, so it read as broken -- which is how it was reported. So the kind, the connection, the directory and the mode move out of the strip above the text and into one toolbar row beneath it, where attach and send already are. The directory becomes a button that opens a browser over SFTP, because a path is something you would rather find than spell. `scan_dir` is new beside `list_dir`: a picker has to tell a directory from a file before it can draw the row, and `list_dir` backs a tool whose contract is a list of names and must not change under a model mid-conversation. Browsing is a person clicking, not a model calling, so it does not pass through policy.py -- the same argument the terminal panel rests on. It does mean Manual mode has a second exception now. Also: .chip was two components with one name, and the attachment card won, so the Chat/Agent pills silently wore its padding. --radius-md was used twice and declared nowhere, so both fell back to 0. .btn.is-active has been set by syncToggles since the terminal landed and styled by nothing. Enter-to-send ignored isComposing, so committing an IME candidate sent the message. The terminal had five colours of a sixteen-colour palette, with fallbacks from a palette that no longer exists.

A terminal panel beside an agent chat
A real shell on the chat's own connection, opened and closed like the inspector and never beside it. The modes govern the model; what a person types is theirs, since they hold the credential and could open the same shell with an ssh client. The model cannot see the panel -- a button copies the output you choose into the composer. The session outlives the socket: closing the panel leaves a build running, and coming back reattaches with the scrollback. Two tabs share one shell and the smaller window decides the size. It ends on an idle timeout, on deleting the chat, on disabling, moving or deleting the connection, and on a restart -- which says why rather than quietly opening a fresh shell that has lost the working directory. The nginx template's `Connection ""` is right for SSE and fails every WebSocket handshake, so `location /` now uses a `map $http_upgrade`; update.sh grows a drift check for it, because the only symptom on a stale vhost is a panel that cannot connect.

SSH connections, kept by the people who own them
An agent chat will act on a machine you choose, so this is the screen where you choose it. User-owned like a note, not admin-owned like a connection: these are somebody's own machines and somebody's own keys, and "anyone in this group may log in to my server" is a different feature with a different blast radius. services/sharing.py is deliberately not involved either -- sharing grants reading, and a host somebody else can read is a host they can log in to. Trust on first use, made explicit rather than assumed. Adding a host does not connect to it. Check looks at its key and shows you the fingerprint; nothing is sent until you accept, because get_server_host_key completes the key exchange and stops -- no username, no credential. Accepting pins it, and a host that later presents a different key is refused with the reason rather than quietly trusted. Moving a profile to another host or port forgets the pin, since a key belongs to the machine it came from. Four asyncssh defaults are actively wrong here and all four are passed explicitly: every LLeMbas user shares one unix account, so `known_hosts` would be a shared trust store, `client_keys` would authenticate one person with another's key, `config` would let a ProxyCommand redirect the connection, and `agent_path` would silently use $SSH_AUTH_SOCK. There is a test for exactly that, and it needs no server. Files go over SFTP rather than through a shell. The SSH exec protocol carries one command *string* that the far side parses, with no argv form at all, so a model-supplied path in a command line is unavoidably a quoting problem. Over SFTP a path is a path. Chat gains its kind, connection, project directory and mode; the first three are fixed once a chat has a message, because a transcript whose earlier turns ran somewhere else is not one conversation.
