A crowd you can find, and a phone 65px too narrow

Two reports against 1.6.0 and 1.7.0, both correct. The crowd worked end to end and was, in practice, not there: the picker was behind the ⋯ menu of a chat that already existed, and the switch was a card on the Agents page, which made it read as an agent-chat feature. The picker is now a button in the composer toolbar on both screens that include it, and on the new-chat screen the choice rides along with the first message, so a chat can start as a crowd instead of having to be converted into one. The instance switch has its own page. The width bug was the suggestion cards, exactly as reported. `.suggestions` rendered 455px inside a 366px column, and the tree's standing rule applied on its own made it worse -- 428px to 455px. A grid item carries `min-width: auto`, which is a min-content floor, and a floor beats `width: 100%`; the floor is measured while the percentage is indefinite, so `min(100%, …)` alone sends the track to a card's max-content. Both halves now go on all four auto-fit grids, and a test refuses either alone. It survived four releases of narrow-width checking because the harness never rendered that screen: `TestClient(app)` runs no lifespan outside a `with` block, so the startup-seeded cards were missing from every shot ever taken of it. And its overflow check skipped anything inside a scroller -- right for a table in its own scroller, blind to the scroller itself, which `overflow-y: auto` makes scroll sideways too. Both fixed; it now names the box and the child to blame. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

 ## Unreleased
 ## 1.8.0
 - **The crowd is where you would look for it.** In 1.6.0 the only way to add a
  model to a chat was the Chat settings panel — behind the ⋯ menu, inside a chat
  that already existed — and the switch that turns the feature on was a card on
  the Agents page. Somebody who enabled it went looking and found nothing, which
  is the correct outcome of that arrangement.
  Now there is a **crowd button in the composer**, beside the attachment and
  scope buttons, on both the chat screen and Messages. It carries a count when
  the chat has a crowd, it lists the models you can reach, and it says what the
  turn will cost before you tick anything. On the new-chat screen the choice
  **rides along with the first message**, so a chat can start as a crowd rather
  than having to be converted into one.
  The instance switch and its bounds have moved to their own page, **Admin →
  Crowd**.
 - Fixed: **the new-chat screen was wider than a phone.** Before the first
  message, the suggestion cards pushed the conversation 65px past the edge of a
  390px screen and it could be dragged sideways; after the first message it
  looked right, because the cards were gone. Reported from a phone.
  Two things were true at once. The cards' grid asked for a minimum column width
  it could not give up — the ordinary version of this bug — and it was *also* a
  grid item, which means it carried a min-content floor that beats `width: 100%`
  outright. Fixing only the first made it 27px worse. Both are fixed, on all four
  grids in the stylesheets that could have it, and a test now refuses either half
  of the pair on its own.
  The reason this survived four releases of narrow-width checking is worth
  recording: the screenshot harness built its client without running the
  application's startup, so the suggestion cards were **absent from every shot
  ever taken of that screen**, and its overflow check deliberately ignored
  anything inside a scrolling box — correct for a wide table in its own scroller,
  blind to a box that scrolls sideways when nobody asked it to. Both are fixed,
  and the harness now names the offending element and the child responsible.
 ## 1.7.0
 - **The interface speaks Slovak.** Pick a language under **Appearance** in your
  own settings, or set what everybody else gets under Admin → General. Your own
  choice wins over the instance's, it is saved to your account rather than to one
  browser, and `<html lang>` finally says what the page is actually in.
  All 969 translatable strings are translated, including the long explanatory
  paragraphs on the admin pages — there is no half-done corner where a Slovak
  instance falls back to English. Dates follow too: a month name is a month name
  in the language you are reading, which `strftime` cannot do without a process
  locale that this application must not set.
  **What is deliberately still in English**: everything a *model* reads. The
  prompt fragments under Admin → Prompts are instructions written for models, and
  translating them would change what the models are told rather than what you
  see. Models answer in whatever language you write to them in — they already
  did, and that line is editable where all the others are.
  An English instance is byte-for-byte what shipped in 1.6.0. That is a property
  of the design rather than a claim: a string with no translation renders the
  English it was written in, so a language added later cannot leave holes in a
  page.
 - Fixed: **every page was rendered in the instance's language, whatever anybody
  had chosen.** Found while building the above and worth naming because it would
  have been invisible: the language was resolved in a dependency that FastAPI runs
  in a threadpool, and the context it was set in is discarded on the way out. Now
  it is resolved in the request's own task.
 ## 1.6.0
 - **A chat can have a crowd.** Switch it on under Admin → Agents, and each chat's
  settings panel offers the other models. The chat's own model answers first, then
  each of the others in turn; then the order runs **backwards**, each one asked
  whether it disagrees with anything said; and it ends back at the first model,
  which either writes the final answer or sends them round again. Every
  contribution is its own bubble with its own avatar, its own metrics and a chip
  saying which speaker it is and which pass it belongs to.
  What it costs is stated where you turn it on and again where you pick the
  models, because it is easy to underestimate: one turn is **models × rounds ×
  2 − 1** replies, so four models over two rounds is fifteen. On a single local
  endpoint every change of speaker also loads a different model. Your own warning
  is built into the defaults — larger crowds start going round in circles — so the
  round limit is two, and it is a limit ordinary work will reach rather than a
  runaway backstop.
  Details worth knowing: each model sees the others' answers **quoted and
  attributed**, never as its own words, so it can actually disagree with them; a
  member you can no longer reach is skipped and said so rather than silently
  dropped; a member whose endpoint fails is skipped, and two failures in a row end
  the round; **Stop ends the round**, not just the model writing at the time; and
  a message typed during a round waits for the round rather than interleaving with
  it. Every sentence a crowd sends is editable under Admin → Prompts.
 - Fixed: **a schedule that named its own model was ignored.** It was written on
  the reply and never sent, so the bubble showed the model you chose while the
  answer came from the chat's model. The same fix makes the crowd possible: the
  reply itself now says which model is answering, rather than the conversation
  deciding for all of them. Regenerating somebody's turn in a crowd keeps that
  model rather than silently switching to the chat's.
 ## 1.5.0
 - **A model's personality is now yours, not the instance's.** Each account gets
  its own version of each model's character: a personality is something a model
  works out *with somebody*, so two people talking to the same model are no longer
  talking to the same one, and neither can see the other's. What a model **is** —
  its description and the facts other models are told about it — stays the same
  for everybody, because that is a property of the model rather than of a
  relationship.
  The box on the model's page is now the **default personality**: the starting
  point somebody has until the model has written its own with them. It is not
  layered underneath theirs afterwards — two personalities at once would
  contradict each other and nobody could tell which was losing. Your own
  personalities, their history, and what each model makes of you are all under
  **Memory** in your settings, and deleting a personality resets it to the
  default rather than removing it.
  ⚠ If you installed 1.4.0 — released and superseded the same day — anything a
  model wrote about you then is sitting in the wrong place and reads as a
  personality rather than as an impression. There is a note in
  `db/migrations.py` with the one statement that moves it; deleting it is just as
  reasonable, since nothing had time to write one worth keeping.
 - Fixed: **a side panel was wider than a narrow phone and hung off the edge.**
  The canvas, the terminal and the details panel all carried a minimum width of
  384px, which beats the rule that was supposed to cap them at the screen — so on
  a 360px phone they were 24px too wide with their left-hand edge cut off, and on
  a 320px one, 64px. Nothing scrolled sideways, which is why a narrow-width pass
  looking for a horizontal scrollbar never found it: the panels are fixed in
  place, and fixed overflow does not make a page scroll. They are now exactly as
  wide as the screen on a phone, and keep their column on a tablet.
  The details panel was worse than the other two: it had no cap at all, and its
  width is a *preference* you can drag to 2400px on a desktop. That number was
  arriving verbatim on a phone.
 - **The Install button now says why it is missing**, instead of not being there.
  Four different things stop a browser installing this and all four looked
  identical; the hint named only the least likely. It now reports whether the page
  is a secure context, what the browser said if the service worker was refused,
  and whether the browser simply never offers it — and names the cause that
  actually bites a self-hosted instance: **a certificate the phone does not
  trust**. A private or self-signed certificate means no service worker, and no
  service worker means no install, however good the rest of it is. Installing the
  CA on the device is the fix, and the app can now tell you that is what is
  wrong.
 ## 1.4.0
 - **Models can be told about each other.** A model may now be given a list of
  the other models on this instance — their names, the id to refer to one by, and
  what each is for — so that it knows what else is available and what each is
  better at. The list is built per person from the models *they* can reach, so it
  never names one they have no access to.
  Each model's page has a new **Facts for other models** box for this: parameters,
  quantisation, a benchmark figure, what it is bad at. The existing description is
  used too, so filling in nothing at all still produces a usable list — but note
  that the description is now read by models as well as by people.
 - **A model can ask another model a question.** New **Ask another model** switch
  on each model's page and a matching permission. The model picks who to ask from
  the list above, writes the question, and gets that model's answer back to use —
  a second opinion from something that is better at the subject, or a check on its
  own reasoning by something that will not make the same mistakes.
  The model answering sees only the question, not the conversation; it answers as
  itself, and it is told to say so if it thinks the question is wrong. It cannot
  ask anybody anything in turn, and it cannot pass the question on.
  It shares the **Helpers** switch and allowance on Admin → Agents, because it
  costs the same thing: one reply setting another reply going. On a single local
  endpoint that also means a model swap out and back, so it is not free.
 - **A model can have a personality of its own, and keep its own read of you.**
  New **Edit its own personality** switch per model. Its character is carried into
  every conversation rather than being an instruction for one, and it is the model
  that writes it — you can seed it, read it, and put any earlier version back from
  the **Personality** card on the model's page. Every version is kept.
  Separately, each model keeps its own impression of how you work: what you
  expect, how you like being answered, what keeps going wrong between you. Its
  point of view rather than facts about you, which is what a memory is for. It is
  per model and per person — two models may honestly reach different conclusions
  about you, and nobody on a shared instance inherits anybody else's.
  **You can read and delete all of it**, under Memory in your own settings. That
  is the whole reason a model is allowed to keep one.
  Two honest limits. A model that has just read a hostile web page can rewrite its
  own character; what stops that being permanent is that every version is kept and
  visible, not that it was prevented — the same position this takes on
  model-written skills. And neither is available to a model running as somebody's
  helper, answering another model's question, or working through a schedule: those
  run on words nobody is watching being written.
 - Fixed: **the model chosen to review generated images was silently forgotten**
  whenever a connection was refreshed while its endpoint happened not to be
  listing that model. Nothing failed — reviewing fell back to the chat's own
  model, so pictures were being judged by a model you had not chosen, with nothing
  saying so. Existing settings keep working.
 - Fixed: **editing a message could leave one of the messages below it behind.**
  Only when two were written in the same millionth of a second, which is exactly
  what happens to a question and the reply being started for it — so the orphan
  stayed in the conversation and in everything sent to the model afterwards.
 ## 1.3.2
 - Fixed: **the model page could not save anything below the reasoning efforts**,
  and had not been able to since 1.3.0. "Save changes" did nothing at all — not
  slowly, not with an error, simply nothing — so the description, the system
  prompt, every capability and tool switch, and the whole availability card
  (enabled, pinned, available to everyone, groups) silently would not take. The
  fields above it, including the display name and the reasoning efforts, saved
  normally, which is what made it look like it worked.
  Worse, the **Detect from the endpoint** button had stopped detecting. It
  submitted the page as an ordinary save instead — a save carrying only the top
  half of the form, so everything below took its empty default: it would have
  cleared that model's description and system prompt and switched the model off
  with all of its tools disabled. If you pressed it, check that model's page.
  The cause was one HTML rule: a form inside another form is not allowed, and
  rather than complaining, a browser discards the inner tag and lets the closing
  tag end the *outer* form. Everything after that point was in no form, and a
  button in no form does nothing. Nothing in the markup looks wrong, and no test
  that posts to a route can see it — so the fix comes with one that reads every
  page the way a browser parses it.
 ## 1.3.1
 - Fixed: **updating to 1.2.0 or later broke every page that lists models**, with
  a 500 and nothing but the error page to show for it. The per-model reasoning
  effort list added in 1.2.0 was the first list-shaped setting this application
  had ever added to a table that already had rows in it, and the code that fills
  in such a column on existing rows could not tell a list from a dictionary — so
  it wrote the wrong kind of empty value into every model, and reading one back
  raised rather than returning nothing.
  A fresh install was never affected, which is exactly why it was not caught:
  the column is only filled in that way on a database that already existed.
  This release both stops it happening and **puts right the rows already
  written**, on start, with nothing to run by hand. If your instance is showing
  the error page, updating is the whole fix.
 ## 1.3.0
 - **A model's reasoning efforts can now be detected rather than known.** There
  is a button on the model's page that asks the endpoint what its chat template
  actually accepts, and ticks those. llama.cpp publishes the loaded model's
  template, and that template is the very thing that rejects an effort it does
  not recognise — so the answer is read from the place that is authoritative
  instead of guessed at, or discovered by a failed reply.
 - Endpoints that do not publish a template — OpenAI, vLLM — say so plainly
  rather than being recorded as accepting nothing.
 ## 1.2.0
 - Fixed: **choosing a reasoning effort could kill the reply outright**, with a
  Jinja traceback where the answer should have been. Reasoning effort is sent
  two ways, and the second — `chat_template_kwargs` — is rendered into the
  model's own chat template, which does not ignore a value it has never heard
  of: it raises, and the whole request fails. The catch is that the vocabulary
  is **not the same for every model**. gpt-oss takes `low/medium/high`; Bonsai
  takes `low/medium/xhigh` and refuses `high`; OpenAI has added `minimal`,
  `xhigh` and `max` at various points. This application offered the same three
  to everything, so on some models the top setting was one the model would
  throw for.
 - **A model now has its own list of the efforts it accepts**, on its page under
  Models, and the composer's picker and `/effort` offer only those. Tick none
  and the familiar three are used, which is right for nearly everything.
 - **And it corrects itself.** If an endpoint refuses an effort anyway — a model
  swapped underneath a name, a runtime upgraded — that reply is retried once
  without it instead of being lost, and the model's list is narrowed so the
  menu stops offering something that does not work. Where the endpoint says
  what it *does* take, that is what gets stored.
 - `/effort` now reads the levels from the picker rather than from a second copy
  of the list kept in the browser, so the two can no longer disagree about what
  a valid effort is.
 ## 1.1.2
 Two things a phone found that 1.1.0's phone pass had not.
 - Fixed: **the administration area could not be navigated on a phone.** Admin
  has a nav of its own rather than the chat sidebar, and 1.1.0 gave every
  sidebar the drawer behaviour — starts closed, slides in — without giving that
  one any of the drawer's furniture. So it sat off-screen with no button to open
  it, no close, and nothing to tap beside it: every administration page was
  reachable and then a dead end. It now opens, closes and dims the page like the
  other one, and a test refuses any future sidebar that cannot be opened.
 - Fixed: **the chat gave nearly a quarter of a phone screen to margins**, so
  anything that could not wrap had to be scrolled to sideways. The thread's side
  padding is halved, and the speaker's avatar moves above the turn instead of
  sitting in a 44px column beside every line of it — a code block gained about
  sixty pixels of readable width.
 - Fixed: **the chat's title was squeezed to nothing.** The row's designated
  shrinker is hidden below a tablet width, so on a phone the controls went rigid
  and asked for 317 pixels of a 390 pixel bar; the heading was not truncated, it
  simply stopped occupying space. The model picker gives now, and on a phone it
  shows its avatar rather than its name — the name is one tap away and the
  title is not.
 - Tick boxes and the smaller buttons are big enough to hit on a phone. A
  checkbox is drawn by the browser at about sixteen pixels whatever the type
  around it, which made it the smallest target in the application by some way,
  and the admin lists are mostly checkboxes.
 - Fixed: **icon buttons could be squashed below their own size.** The sidebar
  toggle measured eighteen pixels across on a phone, under half its target,
  because a full row shrank the button rather than the text beside it.
 ## 1.1.1
 One bug, and it is the one that made 1.1.0 look broken the moment you updated to
 it. If you saw a stray ✕ beside the logo on a desktop, controls that looked
 half-styled, or a page that would not scroll, this is why — and none of it was
 in the code you were running; it was the code your browser had *not* fetched.
 - Fixed: **updating showed you the new page drawn with the old stylesheet.**
  Pages are always fetched fresh, while the CSS and JavaScript beside them come
  from the cache the offline support keeps — and that cache was keyed on the
  release while the files inside it were not. For as long as the previous
  release's worker was still in charge, you got 1.1.0's markup over 1.0.x's
  stylesheet: a close button meant for the phone drawer appeared on the desktop
  with nothing to style or place it, and anything else the new layout depended
  on was simply absent. Every asset now carries the release in its address, so
  a new page cannot be handed an old stylesheet whatever the cache holds.
  It is self-correcting: updating to this version is enough, and no cache needs
  clearing.
 - The sidebar header is two slots — the name, and a rail on the right for the
  drawer's own controls — instead of a brand with a button appended to it. The
  close button sits in that rail, at the top right where it belongs, and a
  second control added later lands beside it rather than pushing the name
  around.
 ## 1.1.0
 Mostly about using this on a phone, where it turns out a good deal of it could
 not be used at all.
 ### The sidebar on a phone
 - Fixed: **the sidebar opened over the page on every phone, and the button that
  closes it was underneath it.** Below a phone width the sidebar is a 280px
  panel laid over the page; nothing ever closed it, and the only control that
  could was in the bar behind it. It now starts closed at that width, slides in
  when you ask for it, dims the page behind it, and closes by tapping beside it,
  by Escape, or by its own button — which is inside the drawer, where you can
  reach it.
 - Fixed: **seven of the eight pages with a sidebar had no way to show or hide it
  at all.** Only the chat page ever had that button. Settings, Messages,
  Reports, Scheduled, Library, Connections and a folder's own page did not —
  which on a phone meant arriving at a page already covered by a panel with
  nothing to do about it. Settings is where the Install and Notifications
  buttons live, so this was also why they were hard to reach.
 - The toggle no longer claims the sidebar is open when it is not, which matters
  to anyone using a screen reader.
 ### Anything you tap
 - **Every control is now at least 44px on a touch screen**, instead of 36px —
  or 28px for the small ones, which included renaming and deleting a chat, all
  seven actions on a message, and every panel's close button. The dismiss button
  on a notification had no size of its own at all and was about 18 by 7 pixels.
 - Fixed: **renaming or deleting a chat, and copying, editing, regenerating or
  reading aloud a message, were impossible on a phone.** All of them appeared on
  hover, and there is no hover on a phone; tapping the row simply opened it.
 - Fixed: **the settings tabs scrolled sideways with nothing to say so**, hiding
  Appearance, Memory and Security off the right-hand edge of a phone screen.
  There is a fade at the edge now, and a flick lands on a tab.
 - Installed on an iPhone, the page ran underneath the clock and the home
  indicator. It no longer does.
 ### Installing it
 - The install prompt now offers the richer dialog rather than the terse bar, and
  a long press on the icon offers New chat, Messages and Scheduled.
 - Fixed: **a light-themed instance installed to a phone showed a near-black
  splash screen and then opened parchment**, and every page load flashed dark
  browser chrome before the stylesheet had run. Both follow the theme now.
 - Fixed: **a new version used to take over pages you were reading**, swapping
  the stylesheets under an open tab while it emptied the cache they came from.
  It waits and offers you a reload instead.
 - Fixed: the small mark beside a notification on Android was a solid grey
  square, because the icon it used has no transparency to be cut from.
 - Fixed: notifications silently stopped working for good if the browser ever
  replaced its own subscription, which browsers do.
 - Pages start loading a little sooner, and the two icons a launcher actually
  crops are now kept for offline use.
 ### Things that move
 - **Every request the application makes now says it is happening**, with a thin
  bar across the top of the window. Nothing did before, so anything slower than
  a few milliseconds looked like a click that had not registered.
 - The thinking indicator turns rather than fading, so a model that is working
  and one that has stopped no longer look alike.
 - Dialogs, the drawer and the panels arrive and leave rather than appearing;
  buttons answer a press; cards lift under the pointer. All of it stops if you
  have asked your system for reduced motion.
 ### Archiving
 - **A chat can be archived** — out of the list, into a group at the bottom of the
  sidebar, and back again whenever you like. The setting behind this has existed
  and been honoured since folders arrived; nothing had ever been able to switch
  it on.
 ### Smaller things
 - **Extra headers can be set on a connection.** They were sent with every
  request already and no form could write them, so OpenRouter's attribution
  headers were documented and unreachable.
 - A model is no longer told that it will hear when a background job finishes on
  instances where that notification is switched off.
 - The guidance for asking you a question can now be edited like every other
  piece of the prompt. It was the only one that could not be.
 - Several controls that a screen reader announced as nothing now have names, and
  two lists that claimed to be tab strips now describe themselves honestly.
 - Borders resolve through a token like every other value, so a theme can change
  one. They were a literal `1px` in about ninety places, which was the largest
  patch of hard-coded value left in the stylesheets.
 - `chat.css` may now contain media queries. It was forbidden them, for a good
  reason that had stopped applying: what the ban protected is asserted directly
  now, which is both narrower and stronger.
 ## 1.0.4
 Six things that looked like they worked. Five of them were found by reading the
 code rather than by anybody reporting them, which is what they have in common:
 none of these fails loudly, and two of them correct themselves if you reload.
 - Fixed: **a reply lost the model's name and picture the moment it finished.**
  While a reply streams it is attributed correctly; at the instant it lands, the
  frame that replaces the bubble was looking the models up as nobody, and "no
  user" answers "no models" rather than "all models". So a finished reply swapped
  the model's avatar for the plain leaf mark, put the instance's name where the
  model's should be, and grew a raw model id beside it. Reloading the page put it
  all back, which is why this survived a release: it is only ever wrong until you
  look away.
 - Fixed: **a limit on how many replies an account may write at once could be
  stepped over by pressing New chat.** It was enforced when sending into a chat
  that already existed and nowhere else — not on a new chat, not on editing an
  earlier message, not on sending a queued one, and not on regenerating. Four of
  the six ways to start a reply ignored it, including the commonest.
 - Fixed: **a custom theme's confirmations and warnings kept the built-in
  theme's colour behind them.** Setting `success` or `warning` moved the text and
  left the background it sits on, because the faded companion colour was derived
  for three of the five settable colours. Visible on every alert and badge of
  those two kinds, on the "on" state in the permissions list, and on the added
  lines of every diff in an agent chat.
 - Fixed: **on a phone, every page with a sidebar could be scrolled past its own
  bottom into empty background.** The shell was sized to the part of the screen
  you can actually see and the document around it to the part you can see with
  the browser's toolbar retracted; the difference between those is real on a
  phone and nil on a desktop, which is why it was never noticed on one. Reported
  on Settings and true everywhere. A flick that ran off the end of a list now
  stops there as well, instead of dragging the page behind it.
 - Fixed: **the conversation was rendering every assistant message twice on every
  page load** — once into Markdown that nothing read, and once the way it is
  actually shown. The same was true of Messages, for your own turns. Nothing
  looked wrong; a long conversation was simply slower to open than it needed to
  be, every time, along with every rewind and every compaction.
 - Fixed: a test file meant to skip itself on a machine without `setsid` never
  did, because it set its marker twice and the second one replaced the first.
 - Removed: an endpoint serving a message's unrendered Markdown, which nothing
  had ever called — the copy button reads the page it is already on.
 ## 1.0.3
 Two Arch-isms in the installer, both of which only a Debian machine could find.
 `deploy/lxc-install.sh` had never been executed — it was reviewed and
 syntax-checked, which is not the same claim — and running it is what found them.
 - Fixed: **`deploy/install.sh` could not create its virtualenv on Debian**, and
  so `deploy/lxc-install.sh` could not finish. It called bare `python`, which is
  Python 3 on Arch — the machine this was written and only ever run on — and
  does not exist on Debian at all unless `python-is-python3` is installed. The
  LXC bootstrap installs `python3`, so the install aborted at the virtualenv
  step with the service user, the bind mount and the clone already made. It now
  calls `python3`, which is right on both.
 - Fixed: the service account was created with `--shell /usr/bin/nologin`, which
  is where Arch keeps it and where Debian does not. Nothing invoked it — `sudo -u`
  execs directly and systemd's `User=` never reads a shell — so the account
  worked either way, but it was created pointing at a file that was not there.
  Now `/usr/sbin/nologin`, which is correct on Debian and resolves on Arch too,
  since Arch's `/usr/sbin` is a symlink to `bin`.
 ## 1.0.2
 - **The documentation moved to the [wiki](https://git.houmeres.sk/Houmeres/LLeMbas/wiki).**
  `CLAUDE.md`, `PLAN.md` and `docs/` are gone from the repository: they are
  documentation *about* this project rather than part of it, and a clone should
  carry software. Nothing was lost — the working notes, the roadmap and the eight
  topic notes are all there, with every internal link rewritten, and the README
  now opens onto them. Where a source comment said "see `CLAUDE.md`" it now says
  "see the working notes".
 - Entries below this one still name `PLAN.md` and `docs/notes/…`, and are left as
  they were written. A changelog records what happened at the time; rewriting old
  entries to match a later decision makes it a worse record, not a better one.

 ## Documentation
 The **[wiki](https://git.houmeres.sk/Houmeres/LLeMbas/wiki)** carries everything
 about how this works and why — it is documentation *about* the project rather
 than part of it, so a clone stays software.
 - **[Working notes](https://git.houmeres.sk/Houmeres/LLeMbas/wiki/Working-notes)**
  — read this before changing anything. The hard rules the project is built
  around, the layout, and a long catalogue of *things that will bite you*: bugs
  that shipped looking correct, why each happened, and what stops it recurring.
 - **[Roadmap](https://git.houmeres.sk/Houmeres/LLeMbas/wiki/Roadmap)** — what is
  built, what is deliberately not, and the reasoning behind each.
 - A page each for agent chats, schedules and reports, permissions and sharing,
  search and extraction, image generation, subagents, branding, and the manual
  release checklist.

  /* --- A box that scrolls sideways when nobody asked it to -----------------
     The blind spot that hid the suggestions bug through forty measurements.
     `.suggestions` rendered 455px wide inside a 390px `.thread-scroll`, and
     every check above looked straight past it: `culprits('x')` skips anything
     with a scrollable ancestor -- correct for a table inside its own scroller,
     wrong for the scroller itself -- and `scrollsSideways` stayed false because
     `.thread-scroll` absorbed the overflow instead of the document.
     "Authored" is the distinction that makes this reportable rather than noise.
     The tree's rule is that anything wide gets its OWN scroller, so a wrapper
     carrying `overflow-x: auto` in a stylesheet is right. A box given only
     `overflow-y: auto` scrolls sideways as well, because the other axis then
     computes to `auto` -- and that is always a bug. Computed style cannot tell
     those apart, both being `auto`, so the rules that say it are read off the
     stylesheets -- in Python, by `authored_sideways()` below, and not from the
     CSSOM here: a stylesheet loaded over `file://` is a foreign origin for
     `cssRules` even with `--allow-file-access-from-files`, and every sheet
     throws. That silently found *nothing authored*, which turns this check into

 """Who a model is with one person, and what it makes of them.
 Both are per **(model, person)**: a model's character is something it develops
 with somebody, so two people talking to the same model are not talking to the
 same personality, and nobody on a shared instance inherits anybody else's.
 `Model.description` and `Model.notes` remain the instance-wide facts about a
 model -- those are what it *is*, not who it has become with you.
 Two tables rather than one with a discriminator, and the reason is a constraint
 rather than taste. 1.4.0 shipped `personas` with `UNIQUE(model_key, owner_id)`,
 SQLite cannot alter a constraint, and this project's schema changes are additive
 only -- so a `kind` column would have left an upgraded instance unable to hold
 both a personality and an impression for one pair. A new table has no such
 problem.
 * **Persona** -- the personality. `owner_id` set is that person's; `owner_id
  IS NULL` is the **default** an administrator writes on the model's page, which
  is what a person starts from before the model has written anything of its own.
 * **Impression** -- what that model makes of that person. Always somebody's,
  never instance-wide.
 Why neither is a fourth prompt layer: *"system prompts replace, never stack"* is
 a decision this project has already taken. Both reach the model as `{{persona}}`
 and `{{person_view}}`, through ordinary fragments, the way the memories block
 does.
 ⚠ **`model_key` is the model's text id, not the `Model` row's primary key**, and
 there is deliberately no foreign key to `models`. "Test & refresh" deletes any
 model the endpoint no longer lists and recreates it when it comes back -- so a row
 keyed on the primary key would lose a model's whole personality to a refresh
 taken while its endpoint happened to be loading something else. This is the
 reasoning `Chat.model_id` already carries: the text id survives, and a row naming
 a model that no longer exists is invisible rather than broken.
 🚨 **An instance that ran 1.4.0 holds impressions in `personas`.** That release
 stored them there, keyed by `owner_id` being set -- which is now what a person's
 own *personality* means. They read as personalities rather than as impressions.
 It is one SQL statement to move or remove them and it is recorded in
 `db/migrations.MANUAL_STEPS`; nothing rewrites them automatically, because a
 repair that cannot tell the two apart would be guessing at somebody's data.

 """Several models answering one turn, in order, then again in reverse.
 The shape the owner asked for: the chat's own model answers, then each other
 member in order; then the order runs **backwards**, each member asked whether it
 disagrees with anything; and it ends at the main model, which decides whether to
 go round again or stop.
 ## Why N chained replies and not one clever one
 One `Generation` per speaker, one `Message` per speaker, chained where `_drain`
 already chains a queued turn. That is not the cheapest shape, it is the only one
 in which every existing invariant keeps holding for the reason it already holds:
 * `Generation` is **one reply's** state and `_follow` streams **per message**,
  keyed on `generation.message_id`. One generation cannot stream into nine
  bubbles without a second streaming protocol, and `ensure(chat_id, message_id)`
  would have no answer to "which of the nine am I" after a restart.
 * Exactly one incomplete assistant row exists at any moment, so
  `_reply_in_flight` needs no teaching and the composer queues for the whole
  round.
 * Each speaker gets its own `steps_json`, `usage_json` and `model_id`, so the
  avatar, the metrics chip and the regenerate button are per speaker with no new
  rendering.
 A subagent per speaker was rejected outright: a helper is handed a *serialisation*
 of the conversation, its answer comes back as a tool result, and tool results are
 never replayed -- so speaker 3 could not see speaker 2, which is the entire point
 of a crowd. That feature already exists and is called `ask_friend`.
 ## Where the round lives
 On the **message row**, in `Message.crowd_json`, and not on the chat. "The row is
 the authority, not the registry" is the rule the reload story was won with, and
 round state on the chat reintroduces exactly the split it was won against: a
 restart between speakers, or a rewind that deletes the rows, would leave
 chat-level state describing turns that no longer exist -- which is the problem
 `Chat.compacted_through_id` already documents.
 `Message.parent_id` is **not** used for grouping. It is reserved for conversation
 branching and says so in its own comment.
 ## The scheduler is a pure function
 `next_turn` takes numbers and returns numbers. Every refusal -- out of rounds, out
 of time, nobody to ask, not the newest message -- is therefore testable without an
 endpoint, which matters because the refusals are the interesting half.

    * **Not the newest message.** `regenerate` calls `restart`, whose `finally`
      runs this again -- and the speakers after it already exist. Without this,
      regenerating member 2 creates a second member 3 and two chains race down one
      turn. `_drain` never needed the guard because a queued row only ever exists

 """Translating the interface, without a build step.
 ## Why not gettext
 `.po` files compiled to `.mo` are a build step, and this project does not have
 one (hard rule 1). So a catalogue is a committed Python module: a dict, keyed by
 **the English source text**, loaded at import.
 Keying on the source has one large advantage and one cost, and the advantage is
 what decides it: **a missing entry renders the key**, which is the English. An
 untranslated string therefore looks exactly as it did before, an instance running
 in English is byte-for-byte what shipped, and a half-finished catalogue degrades
 into a half-translated page rather than into `settings.appearance.theme.label`
 written across somebody's screen. The cost is that editing an English sentence
 orphans its translation silently -- which is what
 `tests/test_translations.py` exists to catch, in both directions.
 This is the shape `branding.FLAVOUR` and `services/prompts.py` already use:
 defaults in code, overrides beside them, and a test that the two agree.
 ## Why a ContextVar
 `t()` has to be reachable from a Jinja **global**, not from the template context.
 `web/templating.render` is bypassed by 25 direct `TemplateResponse` calls and 8
 `get_template().render()` calls, and the second group is the SSE frame path, which
 has no `Request` object at all -- so threading a language through the context
 would leave a third of the application untranslated, and `brand`'s docstring
 records that lesson already.
 But a global is bound once at import and the language is **per person**, so the
 active language cannot live in the global. It lives in a `ContextVar` that
 `LanguageMiddleware` sets per request. That is the one piece of genuinely new
 machinery here; `brand` avoids needing it only because instance branding is the
 same for everybody.
 ⚠ A `ContextVar` is per *task*, and a background reply is a task of its own. It
 therefore does not inherit a request's language, which is correct rather than
 unfortunate: nothing a generation writes is interface text, and the one place it
 matters -- a fragment telling a model which language to answer in -- is a prompt
 variable, not a `t()` call.

  /* 🚨 And the minimum has to give as well, which is the half that was missing.
     `min-width` is resolved *after* `width` and `max-width` and wins over both
     -- CSS sizes an element by clamping width to max-width and then raising the
     result to min-width -- so `width: min(…, 100vw)` above was simply overruled
     by `min-width: 24rem`. Both panels were 384px wide on every screen narrower
     than that, hanging off the edge with their left-hand content cut away, and
     no amount of capping the width would have changed it.
     Because they are `position: fixed`, none of this scrolled the page: fixed
     overflow does not extend the scrollable area. So the failure was content
     you could not reach rather than a scrollbar, which is why it survived a

+  While a model is thinking.
  This was an opacity fade on the icon, which at a glance is indistinguishable
  from an icon that is simply a bit faint -- and "is it working or has it
  stopped?" is the one question this element exists to answer. So it now turns
  as well as breathes, and carries a ring that sweeps: rotation is the thing the
  eye reads as *ongoing* rather than as decoration, and it is the difference
  between a reply that is being written and one that has quietly died.
  Two animations on two elements rather than one compound transform, because the
  icon is a `<use>` of a shared sprite and the ring is a pseudo-element -- and
  because `prefers-reduced-motion` should be able to stop the spin while leaving
  the colour, which two separate declarations allow and one does not.
  No timer, no class to add or remove, nothing to clean up: it stops existing
  when the element does, which is the same reason the animated ellipsis is a
  `content` keyframe.

  `@media` here was lifted: everything below is a *size*, and there is no
  intrinsic-sizing trick that makes 24px of thread padding the right amount on
  a 390px screen. The ban existed to stop the composer toolbar being "fixed"
  with a breakpoint instead of by saying which child gives, and that guarantee
  is asserted directly now (`tests/test_chat.py`) -- so this block may not touch
  `.composer__toolbar` or `.composer__actions`, and a test refuses it if it
  does.
  What was wrong: a 390px screen spent 40px of its width on thread padding and
  another 44 on the avatar gutter before a single word was drawn, which is
  nearly a quarter of the screen given over to margin -- so anything that could
  not wrap had to be scrolled to sideways.

        Reading the answer rather than asking somebody to know it. llama-server
        publishes the loaded model's Jinja chat template on `/props`, and that
        template is the thing that rejects an effort it does not recognise --
        so the accepted set is written down in the one authoritative place.
        Endpoints without that route (OpenAI, vLLM) say so rather than
        pretending the model accepts nothing.
        Its own form, because this page's main form is a PUT of everything and
        a detect must not carry half-edited fields with it — and that form is
        declared before the main one rather than here, with this button reaching
        it by id.
        🚨 It was written inline here, nested inside the main form, which HTML
        does not allow. Nothing complains: the parser *drops* the inner `form`
        start tag and then lets the matching end tag close the outer one — so
        from this point down the page was in no form at all. "Save changes"
        submitted nothing; the description, the system prompt, every capability
        and the whole availability card could not be saved. And this button
        submitted the main form's surviving half to the *save* route, where every
        field it did not carry took its default: description cleared, system
        prompt cleared, and the model disabled with all of its tools off.
        Shipped in 1.3.0 and found in 1.3.2 by asking a browser which form each
        control belonged to, which is the only thing that finds it — the markup
        reads correctly, and a test posting to the route bypasses the parser
        entirely. `tests/test_form_structure.py` is the guard.

            Who else answers.
            Beside the tool switches rather than buried in Chat settings, and
            *inside this form* rather than in the topbar, for one reason each.
            The first: somebody deciding who answers is making the same kind of
            choice as somebody picking the model, and the first version of this
            put it only in the Chat settings panel — behind the ⋯ menu, inside a
            chat that already existed. The owner enabled the feature, went
            looking, and could not find it. A control nobody can find is a
            feature nobody has.
            The second: on the new-chat screen there is no chat row to attach
            anybody to, so the choice has to *ride along with the first message*
            — which means being a field of this form. That is the same mechanism
            the scope switches above use, with the same hidden-input trick,
            because a browser submits only the ticked boxes and `start_chat`
            needs to know which ones were not.
