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 menu for what a chat may use, and three keys
Six smaller things, all of them about the interface not saying what is true.
The @ button only ever inserted the character, which the @ key already does
without a button. It becomes the scope menu: what this chat may use, switched
off per chat. Chat.scope_json is filtered inside resolve_tools AFTER the
capability, permission and instance gates -- exactly as chat.knowledge_bases
narrows knowledge_search -- so a crafted POST turning something on reaches a
tool the gates already removed, and there is a test that writes the column
directly to prove it. Absent means on, for every key, so "why is this off?" has
one answer. It is keyed on the gate rather than the tool name, so notes is one
switch rather than five. The switches carry no role="menuitem", deliberately:
ui.js closes a picker when a menuitem is clicked, which is right for an action
menu and wrong for a list you want to set several of -- which is why the menu
needs no JavaScript at all. Typing @ is untouched.
With no skills, nothing should mention them. tool.skills was gated on the family
alone, so somebody with an empty library was told "the list below gives each
one's name" above no list, handed skill_get, and watched the model spend a round
finding out. It requires skills now; the writing half moved to
tool.skills_write, which is deliberately not gated, because saving the first one
is what somebody with none most needs. And core.tool_list finally reads
tool_names, which had been resolved and documented with no fragment using it.
The composer's toolbar is one row again. .composer__actions is last in the DOM
with margin-left:auto, so the moment an agent chat added a connection, a
directory and a mode, Send and the microphone dropped to a second line.
chat.css has no media queries by design and the fix is not to add one:
.composer__context is the single child allowed to shrink and scroll sideways.
There is a test asserting the file still contains no @media.
The effort picker shows the level in force. "Effort: default" named no level and
was true of nothing in particular; chat.resolved_effort is the chat's own value
and build_request reads the same field, so what is shown is what is sent. The
model's default is a seed, copied onto the row at creation and on a model
change, and never consulted at request time -- a fallback would resurrect it
underneath a cleared effort and make "off" silently do nothing. "off" is a
sentinel and not an empty value, because start_chat declares Form("") and cannot
tell absent from empty: with value="" the reader picks off and gets high.
Alt+M dictates, Alt+R reads the last reply aloud, Ctrl+Enter sends from
anywhere. All three click the button that already does the job, so audio.js
keeps its one delegated listener. Alt+M and not Alt+D, which is the address bar
in Chrome and Firefox. Ctrl+Enter never means Stop -- Send and Stop are the same
element, and Esc already stops. Driven under a DOM stub before committing, per
the rule in CLAUDE.md, and tests/test_commands_js.py pins that every key has a
row in SHORTCUTS, since /help reads that list.
And the memory tooling, which had seven defects. The worst: memory_forget was a
case-insensitive substring first-match delete with nothing warning about it, so
forgetting "coffee" against "Drinks coffee black" and "Allergic to coffee"
silently removed whichever was older -- a wrong deletion nobody would ever find
out about, from a tool whose description invited exactly the short fragment that
misfires. It matches exactly first, then by substring, and refuses an ambiguous
one while naming what it matched. add() refuses an exact duplicate. The
at-the-limit refusal no longer tells the model to delete one to make room: past
the block's budget it is not shown all of them and would be guessing, which
feeds straight back into the first defect. And context.memories no longer claims
the memories "still apply", which nothing checks and which taught a model to
trust a stale one over what the person had just said.

Add nullable columns without a default
Deploying knowledge bases showed the migration runner doing the wrong thing:
ALTER TABLE "documents" ADD COLUMN "base_id" VARCHAR(32) DEFAULT ''
`base_id` is nullable and its absent value is NULL, but the runner derived a
default from the column type and backfilled every existing row with the empty
string. Nothing then matched `base_id IS NULL`, so the startup sweep that files
pre-bases documents into a default base would have skipped all of them and the
documents would have stayed invisible.
Nobody lost anything -- the live instance had no documents yet -- but the fault
is general: any nullable column added from here would arrive as "" rather than
NULL, and every "is this set?" check would be wrong about the rows that predate
it. So a default is now emitted only for NOT NULL columns, where SQLite requires
one.
The sweep also accepts "" as meaning unfiled, since a deployment that upgraded
through the previous release has rows holding it.

Knowledge bases, and a file input that lines up
**Bases.** Documents now live in named collections rather than one flat pile, and a chat can be pointed at particular ones — "answer from the contracts folder" is a different question from "answer from everything I have ever uploaded". A chat with none attached still searches everything its owner can see, because empty means unscoped, not empty. The harness names the attached bases. Without that the model cannot tell "there is nothing about this" from "I am only allowed to see one folder", and it phrases a miss as the former. **Sharing moves to the base.** A document is visible to whoever can see the base it lives in, so `Document` is gone from the shareable types and `documents.visible()` filters through `base_id`. "This folder is the team's" is the granularity people think in; per-document grants meant answering "who can see this?" by checking every file. Moving a document between bases changes who can see it, so the destination has to be one you own. `Document.base_id` is nullable only because the column had to be added to a table that already had rows. `sweep_unfiled()` runs at startup beside the orphaned-upload sweep and files anything predating bases into its owner's default, which is what makes "always set" true everywhere else. **The file input.** `.input` gave it a fixed height and horizontal padding, so the browser's own button sat hard against the left edge while the filename floated off the centre line. A file input is two controls in one box and neither inherits anything useful, so it gets its own rule: no horizontal padding, the button sized to `--control-h` with the divider that separates it, and the text centred with line-height rather than flexbox, which file inputs do not lay out reliably. 437 tests, ruff clean.

Knowledge, notes, memory and skills, and a harness to make them used
Four places a model can reach for, differing in who writes a record and how it gets in front of the model. **Knowledge** is uploaded by a person and searched by the model. It goes through `services/files.py:prepare` — the same pipeline as a chat attachment — so the same PDF produces the same text whichever way it arrived, and `Document` carries the same content columns as `Attachment` for the same reason. **Notes** are written by the model and edited by you. Too long to inject, so they are searched. **Memory** is short facts, and every one of them goes into every request. That single decision is where the rest of its design comes from: records are capped short, the block has a budget, there is no search tool because the model is already looking at them, and they are not shareable — a record about a person is not content to hand round. **Skills** are saved procedures. Only the name and description are injected; the body is fetched when the model decides one applies, which is what makes a hundred skills affordable. A model may write and revise its own — the safety story is not a gate but a record: every revision is kept, attributed and revertible. A model that has just read a hostile page can save a skill that outlives the conversation, and the honest mitigation is that it is visible and undoable rather than that it was prevented. **The harness** is why any of it gets used. A model handed a tools array ignores it and answers from recall, because nothing in the request suggests otherwise. `services/harness.py` assembles a preamble from what this chat actually has: when to reach for each tool, the memories, the skill index. This is an exception to "system prompts are precedence, not concatenation", and a deliberate one. That rule governs the three *authored* layers and is untouched — exactly one still wins. The harness is a different axis: it describes the machinery rather than the behaviour, nobody authored it, and there is nothing for it to disagree with. It is prepended to whichever authored prompt won, in one system message, since several endpoints reject a second. Supporting changes: - **Sharing**, in one helper. `visible_to()` is the only definition of who can see a library item and every listing and tool goes through it. Sharing grants *reading*; two people editing one note with no history and no merge is worse than copying it. **Administrators do not bypass this** — they bypass permissions elsewhere because an admin can grant themselves those anyway, but reading somebody's private notes is a different act. - **FTS5**, created by `db/migrations.py:ensure_fts` with the triggers an external-content index needs. Idempotent, like the column sync beside it. Terms are ANDed and then ORed: the caller is usually a model writing a whole question, and requiring every word loses the match on one absent term. - **The attach button is a menu** — file, image, a web page, or a document from the library. Attaching a document copies it, because history must not change when a document is edited later. - **A URL fetcher with an SSRF guard.** This server can reach the router, the other services on the box and LLeMbas itself, and the address can come from a model. Private ranges are refused *after resolution* and redirects are followed by hand so every hop is checked. An admin can open it deliberately. - **Model capabilities split** into protocol support and a toggle per built-in tool. Rows predating the split have no `tool_*` keys, and absent counts as on when `tools` is on — otherwise an upgrade silently takes web search away from every model already configured for it. Also fixes the test fixture, which built the schema with `create_all` and so ran against a database without the FTS tables production has; it now runs `sync_schema`, the same path startup takes. 430 tests, ruff clean.
