Temporary chats
A clock in the top-right starts one. It is never listed in the sidebar and is swept a day after the last thing said in it. A real row rather than something held in the browser, because a reload, a crash or a background tab all look identical from here -- "delete when you navigate away" would lose conversations people meant to keep. The flag rides in the URL (/chat?temporary=1) rather than in JavaScript, so it survives a reload and can be bookmarked, and the composer carries it as a hidden field beside model_id. Keep clears the flag. Without a way out, a conversation that turns out to matter is destroyed a day later with no recourse, and people would find that out exactly once. archived was filtered in three places and temporary mirrors all three, plus Folder.visible_chats. It also skips the unread flag in _persist: there is no sidebar row for the dot to land on, and the toast would name a chat nobody can navigate to. The sweep measures age from the newest message, not from the chat row. created_at would destroy a conversation still in use at hour 23, and updated_at does not move when a message is inserted -- onupdate fires on an UPDATE of the chat, and adding a message is not one. It runs at startup beside the existing upload sweep. Deleting a chat cascades its rows but leaves the files on disk; only the orphan sweep unlinks anything, and it looks only at uploads that were never attached. files.remove_files_for_chats() closes that for the new sweep. The same hole in delete_chat is pre-existing and left for its own change, which can now call the same helper. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

One thread template, one sidebar toggle
chat/index.html and chat/_thread.html held the same loop, so anything added to the conversation -- a compaction divider, say -- would have had to be written into both and kept in step by hand. index.html includes the partial instead. The sidebar toggle was a raw inline onclick, the only one left in the application. app.js already delegates [data-toggle="#selector"] and gives open/close, aria-expanded and an is-active button state for free; the chat settings gear has used it all along. Also deletes the .sidebar[data-collapsed="true"] rule, which nothing has ever set. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Green instead of gold, and a leaf that reads at 16px
The brand accent was rune gold. It is now mallorn green: --gold becomes
--leaf in tokens.css and everywhere it resolved, and the mark's wafer is
the green of the leaves lembas travels wrapped in rather than the biscuit
inside. Yellow is left to mean exactly one thing in the interface -- a
warning -- instead of two.
Two knock-on choices the rename forced:
- Code keywords move from the brand accent to --warning. Strings are
--success, which is green; keywords in leaf green beside them is not
a colour scheme.
- --success itself leans teal now. Two greens a hue apart read as one
colour rendered badly, and an unread dot has to be tellable from a
brand badge at a glance.
The mark is redrawn, not just recoloured. The blade is ovate -- widest a
third up from the base, rounded where the stem meets it, drawn out only
at the tip -- because the old one was pointed at both ends and read as an
eye. It is also much larger relative to the tile: at 16px the silhouette
is all that survives, and a small leaf on a large tile is a green square
with a smudge on it. Veins sweep towards the tip and shorten as the blade
narrows. The score cross is thinner and fainter so it stays texture.
A single diagonal score was tried first and rejected: behind a diagonal
leaf it does not read as scoring, it reads as a line struck through the
mark.

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.

PWA, one send/stop button, audio in and out, web search as a tool
Four pieces of work.
**Installable.** A manifest carrying the instance name, PWA icons rasterised
from the existing mark at design time, a service worker and a themed offline
page. The worker caches the shell only and bails out on /api/, /auth/, /admin/
and anything accepting text/event-stream -- passing a reply stream through a
worker turns it into one delivery at the end, or nothing. It is served from
GET /sw.js rather than the static mount because a worker's scope is the path it
came from.
**Send and Stop are one button.** They were two, and the hidden one was never
hidden: `.btn` is display: inline-flex, which outranks the browser's own
`[hidden] { display: none }`, so Stop sat permanently beside Send. app.css now
forces the attribute to win -- every control toggled with `hidden` depended on
that -- and the composer renders one button carrying both icons, with ui.js
flipping data-composer-action and the type with it.
**Audio.** Speech to text and text to speech against any OpenAI-shaped
/v1/audio/* endpoint: dictate into the composer, have a reply read out.
Instance settings in Admin, per-reader overrides in Settings, with the voice
list discovered from the server where it offers one. Recorded audio is capped
and never written to disk -- it is not an attachment, it has no owner, and
nothing would ever sweep it.
**Web search, as a tool.** This is the tool loop PLAN.md described as the real
work: one reply is now a bounded sequence of requests rather than one. The model
asks, the tool runs, the result goes back and it is asked again, up to three
rounds. Providers are DuckDuckGo (no setup), SearXNG and Firecrawl.
Two decisions worth stating. Tools are only offered to models flagged `tools`,
because an endpoint without support rejects the whole request rather than
ignoring the array -- the same reason images only reach models flagged
`vision`. And tool results are not replayed as context on the next turn, for the
same reasons reasoning is not: the answer already contains what the model made
of them, and replaying stale results into every later request wastes the window
and reliably sends a small model into a search loop. The sources stay visible in
the transcript instead.
Search results are untrusted third-party text and are treated as such: escaped,
and only http/https URLs rendered as links.
338 tests, ruff clean.

Live Markdown, stop, rewind, custom picker, dialogs
Seven things. **Reasoning starts closed.** The answer is what the reader is waiting for; the thinking is one click away. **Image borders.** .attachments__image was a block-level <a>, so its border stretched the full column around a narrow picture. inline-block, and the frame is the picture. Same fix for the composer thumbnail. **Markdown now renders during the stream.** The generator re-renders the answer so far and sends it as a `render` event at most every 100ms, swapped with innerHTML, instead of appending escaped tokens and formatting everything at the end. Re-rendering whole rather than appending is the point: a list or a code fence is only correct once its context exists, and partial syntax resolves itself as more arrives. Measured against a live model: 29 render events, formatting visible from the first content token. **Stop button.** A stop request goes into an in-process set the generator checks between chunks; whatever arrived is kept, because a half-written answer the reader chose to cut short is still worth having. Measured: stream ended 0.2s after the request, 1155 characters preserved, message marked stopped rather than errored. Navigating away does the same thing via CancelledError. **Rewind and edit.** Edit one of your own turns and everything after it is deleted, then the conversation runs on from there. Deliberately not branching: that needs a UI for choosing between versions, and "go back and try again from here" is what was asked for. The form states how many messages will be discarded before you confirm. **Custom model picker.** A <select> renders only text in an <option>, so it can never show an avatar. Built from buttons and a hidden input, with descriptions, capability tags, a filter box past eight models, and arrow-key navigation written out by hand since there is no native widget doing it. **Notification system.** lembas.notify/confirm/prompt in ui.js, built on <dialog> so focus trapping, Escape and page inertness come from the browser. htmx:confirm is intercepted, so every existing hx-confirm gets the themed dialog with no change at the call site; the browser's grey confirm() is gone from every template. 230 tests, ruff clean.

Fix bulk actions, create chats lazily, rework the UI
Seven reported problems.
**Bulk model actions 404'd.** /admin/models/{model_id} was registered
before /admin/models/bulk, and FastAPI matches in registration order, so
"bulk" was parsed as a model id. Moved above the parameterised route,
with a comment saying why, and a regression test.
**Empty chats piled up.** There is now no endpoint that creates one.
"New chat" is a link to /chat, which renders a composer with no row
behind it, and POST /api/chats/start writes the chat together with its
first message. Opening one and walking away leaves nothing.
**Pinning meant two different things.** The picker is now always in the
administrator's position order; pinned models get shortcuts in the chat
sidebar and nothing else. A picker whose order silently differs from the
admin screen is just confusing.
**Model images were missing in chat.** Assistant bubbles now show the
avatar of the model that actually wrote the turn -- which is not always
the model the chat is set to now -- falling back to the LLeMbas mark.
The picker shows it too.
**No global or per-model system prompt.** Three layers now: instance
(Admin -> General), model (Admin -> Models), chat. Precedence, not
concatenation: most specific wins outright. Stacking them reads well in
a settings screen and badly in practice, because two layers that
disagree give the model contradictory instructions and nobody can tell
which is losing. The chat panel shows the inherited prompt as
placeholder text so "leave empty to inherit" is not a guess.
**Alignment and button sizing.** Added --control-h and friends to
tokens.css; every button, input and select takes its height from them,
so a mixed row is flush by construction rather than by per-instance
nudging. Icon buttons are square at that height. Added .btn-row,
.card__header/.card__footer and .grid so pages stop carrying inline
styles, and moved every admin page onto them.
**Settings needed structure.** The user settings page is now tabbed
(Account / Models / Appearance / Security) using radio inputs and
sibling selectors -- no JavaScript, and the browser keeps the chosen tab
across a re-render.
Caught while checking: the chat.css surgery had deleted the attachment,
chip and dropzone rules. Restored, and there is now a check that every
literal class used in a template has a CSS rule.
197 tests, ruff clean.

Working chat: auth, connections, streaming, folders
LLeMbas now runs end to end. Register, add an OpenAI-compatible connection, and hold a real streaming conversation organised into folders. Verified against the local llama-swap instance. Streaming is the one genuinely tricky part. Sending a message returns two HTML fragments -- the user bubble and an empty assistant bubble carrying an sse-connect -- and that attribute is the ONLY thing that starts a generation. Rendering an incomplete assistant message as a streaming shell falls out of the same template, which means loading a page whose last reply never finished simply picks it up again. Details worth knowing about, each commented where it matters: - SSE payloads are split across several data: lines. A raw newline in one data: line truncates the event, which shows up the first time a model emits a code block. - Markdown is rendered server-side by the same helper for both the page and the final streamed frame, so the two cannot disagree. The fence renderer is replaced outright rather than using markdown-it's highlight option, which re-wraps output in a second <pre>. - escape_text is html.escape, not nh3.clean_text: it escapes character by character, so escaping stream chunks separately equals escaping the whole string. - The stream opens its own session via session_scope(); it outlives the request handler and the dependency-scoped session may be closed. - Deleting a folder keeps the chats inside it (FK is SET NULL). Losing a conversation to a mis-clicked folder delete is unforgivable. - Login failures use one message for "no such account" and "wrong password" so the form cannot enumerate registered addresses. Also adds deploy/ for the gamebox install at https://chat.lan: system unit, nginx vhost with buffering off (buffering on turns streaming into one lump at the end), and install/update scripts following the same service-user and /srv bind-mount conventions as llama-swap and comfyui. 70 tests, ruff clean.
