Narrow a chat before it starts, and find a file rather than spell it
Six things, all found by using the thing rather than by reading it. The scope menu only appeared once a chat existed, on the reasoning that there was no row to post to. True, and the wrong conclusion: the harness puts a tool's guidance in front of the model the moment the tool is offered, so the menu could not be reached until after the model had been told how to keep notes and handed the tools to do it -- and switching it off then does not un-send that turn. It is on the new-chat screen now and writes nothing: `_scope_context` builds a stand-in Chat, which is `draft.as_chat`'s trick again, and the switches ride along with the first message. Checked means on and a browser submits only the ticked boxes, so every gate also renders a hidden input naming it and `start_chat` subtracts one list from the other; inverting the control would read backwards under a menu that says everything is on unless you say otherwise. Only the off ones are written, because absent means on and one representation of it is what keeps "why is this off?" to a single answer. Nothing is validated against the offered set, since scope_json narrows after every gate -- naming a gate that was never offered switches off something that was not on. Then the scheduling instructions, audited against a 4B model on this machine rather than against my own reading of them. Ten realistic requests, ten compiled, twice over -- so the prompt is sound. What was not sound was `describe`, which built a phrase by joining fragments and read "Every the 1st at 09:00" for the commonest monthly schedule there is, and "Every of January" for a month with no day. That string is the whole of what somebody sees before approving a schedule and the whole of what the model is told about its own chat, so a phrase nobody can parse is a review step nobody performs. It reads as English now, collapses Monday-to-Friday to "every weekday" and seven days to "every day", and every case in the test is a rule that model actually produced. The one mistake it made was naming Wednesday for "every other tuesday", so the weekday numbering is spelled out rather than left as "0-6, Monday is 0": getting that wrong is the error here that still looks like a working schedule. Roughly one call in six also came back empty -- a local runner swapping models under the request will do that -- so an unusable reply is asked for once more before giving up. Not on an LLMError: an endpoint that refused will refuse again, and the reader is better served by the form than by waiting twice for the same answer. Canvas asked for a typed path, which was the last control in the application expecting somebody to remember an absolute path on another machine -- the same complaint the folder page's directory field answered with a picker. /browse takes pick=file and the same fragment makes files buttons, because a second copy of that listing is a second place for the path arithmetic to be got subtly differently. The button carries data-canvas-open rather than an hx-post since the path is not known until the dialog closes, and ui.js posts it through htmx.ajax so the response lands in the panel exactly as every other canvas action's does. The key is `agent:<path>`, so a file opened by hand and one opened by the model are one tab rather than two spellings of it. The tabs already existed and already closed; they now square off at the bottom and the active one takes the body's background, so which is selected is structural rather than a tint nobody can see in a theme they did not choose. Highlighting was already there for every language named and is checked for fifteen of them. Three smaller ones. Tabs kept their scroll position, so switching from a long panel to a short one left the browser clamping to that panel's bottom: the end of it above a screen of nothing, which reads as a page that failed to load. Nothing in CSS can reset a scroll position. The sidebar's footer and the composer sit either side of one vertical edge and were both content-sized, so their top borders met it at different heights and read as one line that had been broken -- `--footer-height` is a calc of the pieces the footer is built from, applied as a min-height to both, which is exactly what `--header-height` already does at the top of the shell. And "Add a workflow" sat flush against the list it adds to, stated as an adjacency because `.btn-row` is right to carry no margin everywhere else it appears. Both pieces of JavaScript were driven under a DOM stub before committing, which is how the tab listener's delegation and the canvas button's six behaviours were checked at all -- `node --check` parses a file that does nothing.

Look around the machine before deciding to talk about it
The terminal and the canvas both needed a Chat, so they were missing from the one screen where you are choosing which machine to work on. A draft is the smallest thing that fixes it: an id, and the three facts behind it. The trick is that a draft resolves to a *transient* Chat -- constructed, never added to a session. `canvas.agent_ready`, `_executor`, `_load_agent`, `_save_agent` and `agent_session.resolve` read exactly four attributes between them and none of them queries or writes the row, so all of it works unchanged and nothing had to learn what a draft is. Proven against a real sshd rather than a stub: a transient chat opens and saves a project file over the same SFTP path a real one uses, and the database stays empty throughout. Chats are still created lazily. A draft is not a chat and never becomes one; when the first prompt makes the real one, the shell is re-keyed into it and the open tabs are copied across. `terminal.rekey` moves the registry key *and* `session.chat_id`, because close_for_profile, close_for_owner and the reaper all pop by the field -- a stale one would leave a dead session that `get` keeps handing out. The shell is only adopted when its profile and directory match the chat as finally resolved, since `_new_chat` settles an empty directory to the connection's own; otherwise it is left alone rather than transplanted onto a chat that says it runs elsewhere. Two canvas sources are refused on a draft, by name, and one of them is a hole rather than an inconvenience. `_load_file` authorises with `attachment.chat_id != chat.id`, and an upload made on the new-chat screen is stored with `chat_id=None` -- so a draft whose chat carried no id would make that comparison `None != None`, which is False, and open every unclaimed attachment its owner has. `as_chat` does set an id, so it already fails; the refusal is stated anyway, because a guarantee that lives in an id-shaped coincidence is one the next change breaks without noticing. Adoption needed almost no JavaScript: start_chat already answers with HX-Redirect, so the page reloads and the canvas adopts by construction while the terminal reconnects to the re-keyed session and replays its scrollback -- the "a reload is indistinguishable from a second tab" property working for us. What re-points them mid-screen is a `lembas:agent-target` event, dispatched from `setDir` and the connection select because assigning to a hidden field's value fires nothing on its own. Driven under a DOM stub before committing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

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> |
