The interface speaks Slovak

969 strings, an instance default and a per-person choice, and no half-done corner: the admin prose is translated too. Design and reasoning: LLeMbas.wiki/Translations. KEYED BY THE ENGLISH SENTENCE A missing entry renders the key, which is the English -- so an untranslated string looks as it always did, an English instance is byte-for-byte 1.6.0, and a half-finished catalogue is a half-translated page rather than a page of dotted key names. The cost is that editing an English sentence orphans its translation silently, which is what tests/test_translations.py asserts in both directions. No gettext: .po -> .mo is a build step and this project does not have one. A JINJA GLOBAL, AND THEREFORE A CONTEXTVAR `t()` is a global for the reason `brand` already documents -- render() is bypassed by 25 TemplateResponse calls and 8 get_template().render() calls, the latter being the SSE frames, which have no Request at all. A global is bound once at import and the language is per person, so the active language is a ContextVar set per request. 🚨 `get_current_user` had to become `async def`. FastAPI runs a sync dependency in a threadpool, and anyio copies the context in and discards it on the way out -- so the language was set where nothing could see it and every page rendered in the instance's language whatever anybody had chosen, with no error anywhere. NOT TRANSLATED, ON PURPOSE Everything a model reads: the 60 prompt fragments, and the dates in harness.py, schedule/runner.py and schedule/compile.py. Only `i18n.stamp` is localised, and only where a person reads it -- with the *format* translatable as well as the words, because "26. septembra 2026" is a different pattern rather than the same one with different words in it. A process locale is not an option: global, not thread-safe, two people's pages at once. A second fragment telling models to answer in the reader's language was written during this work and removed: `core.style` has said it since long before, and test_an_empty_override_turns_a_fragment_off caught the duplicate. THE BULK PASS 1213 sites wrapped by a one-off script that only touched patterns it could not misread. It got three wrong in a way that mattered -- `t('…')` inside `attr="…"` where the sentence held an apostrophe, closing the Jinja string and 500ing two pages whose partials no test renders. tests/test_translations.py now compiles all 110 templates. It also wrapped the product's own name, an SSH key header, a keystroke hint and an example URL, all taken back out: a string is not translatable just because it is a string.

 ## Unreleased

+## 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.
+

+"""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.

+"""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.

+        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

+        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.
+

+        entirely. `tests/test_form_structure.py` is the guard.
