feat: self-hosted media — streaming, ComfyUI generation, video cutting, transcription (#119)

* chore: remove legacy orchestrator, trading and one-off script leftovers

The repository still carried the pre-evOo prototype: a Python orchestrator,
the old HTML "evoo-platform" cockpit (whose test ran in the root unit
suite), an apex-trading package, the hot-reload deploy.sh for it, a
permissions manifest, an architecture note with local file links, agent
handoff notes, a Steve Jobs persona template and about ninety one-off
scripts that probe a developer database with hard-coded local URLs. None
of it is used by the product, CI or the real deploy in ops/evo-deploy.

Delete those files, drop the evoo-platform test glob from the root vitest
config, the Cockpit section from .env.example and the dead biome and
gitignore entries, and update the docs that listed the removed tools.
scripts/start-tmux.sh no longer starts the removed sentinel and resolves
the checkout from its own location instead of a machine-specific path;
scripts/seed-ollama.ts requires DATABASE_URL instead of falling back to a
local URL with a username.

* feat(media): add media contracts, schema and provider interfaces

Groundwork for image and video generation, video editing and transcription.
Nothing calls it yet; the media runner, providers, tools and UI build on it.

- Contracts: video, audio and subtitle MIME types, per-kind size caps for
  streamed and generated artifacts, video/audio message blocks and the live
  media card block, media operations, job statuses and output presets
  (9:16, 16:9, 1:1, 4:5, 4:3, 21:9).
- Core: attachment kinds include video and audio, artifacts become video or
  audio blocks, and agent history keeps media artifact ids so later turns
  can refer to them.
- Schema: artifacts record width, height, duration and the artifact they
  were made from; media_jobs tracks generations, edits and transcriptions.
- Adapter kit: provider-neutral image generation, video generation and
  transcription interfaces, the media job context operations run in, and
  the MediaRuntime that tools use to start jobs.

* fix(web): drop trading and persona prompts from the conversation shell

The web shell still showed leftovers from the trading prototype: composer
chips with German trading and "Steve Jobs" prompts, trading suggestion
chips under the empty conversation line, a German trading hero for the
empty transcript, and a German "data protection" status panel in the
sidebar. They suggested actions the product does not have and added
persistent chrome.

Remove the composer chips and their helper, the empty-state chips and the
hero (the empty conversation keeps its existing one-line start hint), the
sidebar trading indicator and the data trust panel. The new-bot E2E now
asserts the plain empty state; the sidebar spec no longer expects the
trading status, and the placeholder Steve Jobs spec with no assertions is
gone.

* refactor: remove the trading bot status integration

With the sidebar trading indicator gone, the only remaining consumer of
the trading bot status was a banner in General settings that reused the
same component. evOo is a personal assistant; a status proxy and poller
for one external trading service, configured through service-specific
TRADING_BOT_URL and VITE_TRADING_BOT_URL variables, does not belong in
the core product.

Remove the settings banner and its prop plumbing, the web poller, the
indicator component, the /api/trading-bot/status proxy, the shared core
contract, the env loading and both variables from .env.example, together
with their tests.

* chore: remove one-off database scripts and a stale review note

packages/db carried four hand-run scripts outside the package build that
query or seed a developer database with a hard-coded connection string,
one of them for a specific account. docs/VOICE-FIRST-REVIEW.md was a
one-time verification note for a workflow that no longer exists and
named private machines and local paths. Nothing references them.

* feat(memory): remember appends dated notes instead of replacing memory

The remember tool rewrote the bot's whole MEMORY.md with each call, so every
new fact erased the earlier ones unless the model re-sent the full document.

- MemoryCommitRequest gains mode "append" (the store joins the note onto the
  current content inside the same serializable transaction and still writes a
  revision row) and every commit is capped at 16 KB per document.
- remember appends a dated bullet ("- YYYY-MM-DD: ...", the user's local date)
  by default and rewrites only with mode "replace"; a full document returns an
  error that tells the bot to condense it. Retries of the same tool call stay
  single appends through the existing effect record.
- Scripted runtime memory entries can append too; the scripted "remember"
  script now appends instead of overwriting the bot's memory.
- When memory does not fit the run's 32 KB budget, the prompt keeps a
  document's newest lines instead of its oldest.
- memory.update maps an oversized save to BAD_REQUEST.
- docs/PRODUCT.md records that UserFact is the cross-space user model and the
  space MEMORY.md stays space notes (no migration).

* feat(coach): goals, habits, check-ins, daily briefs and check-in rhythm

The main agent should coach the user, but nothing stored what the user
wants to achieve or keep doing, and no routine ever checked in. This adds
the data model and the interfaces the onboarding intake and the coach
tools build on.

- Schema: UserGoal, Habit, CheckIn (one per habit, goal or day and date)
  and DailyBrief, all keyed to the user's local calendar date, plus a
  coachKey on Routine that marks the main bot's coach check-ins.
- Contracts (coach.ts): CoachRhythm, Goal, Habit, CheckIn, DailyBrief and
  CoachToday DTOs and the RPC inputs.
- Repository (@rakazo/db coach.ts): goal, habit and check-in CRUD with
  per-user limits, upsertDailyBrief and loadCoachToday with streaks in
  the user's time zone.
- coach-rhythm.ts: setCoachRhythm/getCoachRhythm keep up to three main
  bot routines (morning brief, evening check-in, weekly review) in the
  main conversation in step with the user's chosen times.

* feat(notifications): add push subscriptions, notification settings and web push interfaces

Push could only reach one mobile device per user (a token file), quiet hours did not exist,
and the web app had no service worker, so a closed tab never heard about finished work.

This lands the shared interfaces first so onboarding can build on them:
- push_subscriptions (web push endpoints and Expo tokens, one row per device) and
  user_notification_settings (quiet hours as minutes in the profile time zone, nudges, a
  per-day nudge counter), with CHECK constraints.
- NotificationSettingsSchema and web push contracts, notifications.settings.get/update and
  notifications.webPush.config/subscribe/unsubscribe (owner-scoped, https endpoints only).
- getNotificationSettings/updateNotificationSettings plus the policy and nudge-cap helpers.
- VAPID keys from VAPID_PUBLIC_KEY/VAPID_PRIVATE_KEY or generated once and stored encrypted,
  and an SSRF-guarded web push sender built on the web-push package.
- The web app links its manifest, registers a push-only service worker where supported (secure
  context, not the desktop app) and exposes webPushSupported/webPushEnabled/enableWebPush/
  disableWebPush.

* chore: replace machine-specific paths and addresses with placeholders

ORIGIN.md pinned the intended checkout to an absolute path under a
personal home directory, docs/LOCAL-SETUP.md listed folders on one
developer's machine, and two tests used what looks like a real tailnet
address. Use a home-relative path, drop the machine-specific folder list,
and use 100.100.100.100 in the tests; it is still inside 100.64.0.0/10,
so both tests check the same thing as before.

* test(coach): repository, streak and rhythm suites

Covers what the coach interfaces promise before anything builds on them:
goal and habit ownership and limits, one check-in per habit, goal and day
dated in the user's time zone, streaks across weekends and weeks, and a
rhythm that keeps exactly one main-bot routine per check-in and is
idempotent when set again.

* refactor(contracts): share one clock-time schema

The coach rhythm and the quiet hours both parse "HH:MM" wall-clock times
and each defined its own ClockTimeSchema, which the contracts index cannot
export twice. Both now import it from one module.

* feat(onboarding): ask the onboarding questions in the main conversation

The wizard asked for the account name again and a "Tell us about yourself" form, and the
focus answer in the main conversation was never saved. The main bot now gets to know the
user in the main conversation instead, one card after each answer.

- UserOnboarding keeps the pending step, the focus and when onboarding finished.
- onboarding-intake.ts declares the steps (focus, goal, rhythm, quiet hours, notifications)
  as cards plus what their answers change; onboarding.ts commits an answer, the focus app
  suggestions and the next card or the closing line in one transaction.
- The choice block gains a step, an optional text input and the typed answer; choose takes
  the step, the text and whether the device can still turn push on.
- The focus answer becomes a goals fact; the goal, rhythm and quiet-hours effects and the
  push seam are placeholders until the coach and notification modules are merged.
- The wizard drops the preferences step and fills time zone, locale and language from the
  browser; the main bot's prompt notes open onboarding cards; agent history shows a card's
  question and answer.

* feat(media): transcribe speech on any OpenAI-compatible server and write subtitles

Transcription has to run on the user's own hardware, and the only speech-to-text
path so far was the OpenAI voice key. Self-hosted whisper servers (whisper.cpp,
faster-whisper based servers, vLLM) all speak the OpenAI transcriptions
protocol, so one provider covers them.

- createOpenAiCompatibleTranscriptionProvider posts a multipart upload to
  {base}/audio/transcriptions asking for timed segments, falls back to plain
  JSON for servers that reject verbose_json, reads text/plain bodies, and
  reports failures in words. It reuses the address-checked fetch and URL
  guards of the other OpenAI-compatible adapters, caps uploads at 25 MiB and
  responses at 8 MiB, and builds the multipart body by hand because the
  undici fetch behind the address checks does not serialize the global
  FormData class.
- An in-process server emulator (OpenAI/whisper.cpp, plain-JSON-only and
  text-only flavours) and an in-process provider back an offline
  conformance suite, plus one loopback test through the real fetch.
- toSrt/toVtt in core turn segments into SubRip and WebVTT, wrapping long
  segments into cues of at most two 42-character lines that share the
  segment's time, and escaping WebVTT cue text.

* feat(notifications): fan push out to every device, honour quiet hours, add notify_user

Run notifications reached at most one phone and nothing could hold them back at night.

- PushNotificationProvider sends each notification to all of the user's registered devices
  (web push and Expo), skips everything during quiet hours in the profile time zone, drops
  devices the push service reports gone (404/410, DeviceNotRegistered), records lastUsedAt and
  links each push to its conversation.
- Expo tokens move from DATA_DIR/push-tokens files into push_subscriptions: the API imports and
  deletes the legacy files at start; notifications.registerPush/unregisterPush keep their
  contract for the mobile app (tokens must look like Expo tokens).
- NotificationMessage gains the nudge kind, and the main bot gets notify_user: a short push to
  the main conversation that respects the nudge switch, quiet hours and a cap of three per day.
  It is withheld from shared messaging channels and from runs answering another owner's agent.

* feat(coach): main-bot coach tools and goals in its prompt

The main agent had no way to record what the user wants to achieve or how
their day went, and its prompt never showed their goals or habits.

- update_goal, update_habit, log_check_in and write_daily_brief, main-bot
  only and, like update_user_profile, withheld from shared channels and
  from runs that answer another owner's agent. Goals and habits can be
  named by id or exact title.
- The main bot's own runs list active goals and habits (with ids, done
  state and streak) in the <user> block; the basics-only block and every
  other bot never see them. The main agent role adds a short coaching
  stance and names each coach tool only when the run has it, so the
  check-in routine prompts stay tool-agnostic.
- The scripted runtime understands a few coach commands and the morning
  check-in, so tests can drive the tools end to end.

* feat(media): add the Studio specialist the main bot hands media work to

Media work (cutting for a format, subtitles, exports) needs editing judgement
and a focused tool set, so the main bot should be able to delegate it to a
visible specialist instead of doing it itself.

- ensureStudioBot creates "Studio" once per user, next to the main bot so it
  can join the main conversation and read its media, tagged media, with
  editor instructions (hook first, tight pacing, 9:16 safe areas, subtitles
  for muted playback) and a restricted builtin allowlist: every media
  operation plus files, questions, memory and web lookup. It has a thread,
  so the main bot's specialist directory lists it. The spawn key carries the
  user id so members of a shared space each get their own.
- A Studio the user archived or deleted stays gone. Deleted bots now record
  their spawn key in bot_deletions so idempotent creation can tell.
- Postgres suite for concurrency, shared spaces, archive and delete.

* fix(web): use English Lingui sources for German UI text

Several web surfaces hard-coded German (the project card, roster and
activity status labels, the sidebar "Heute" label) or used German text as
the Lingui source message (sidebar sections, project timeline, bot picker,
voice entry, group stage, copy and read-aloud buttons). English users saw
German, and because production builds keep only message ids, none of these
strings could be translated per locale.

Convert them to English source messages, keeping the meaning:
- ProjectCreatedCard: Lingui Trans/Plural instead of literals.
- agent-activity: labels go through i18n._ with literal ids so the module
  stays importable from plain unit tests; the extractor still collects them.
- Shell, ProjectSessionTimeline, bot-picker, StageVoiceEntry, OoStage:
  English sources, reusing existing messages where one already fit
  ("just now", "{n}m ago", "Search", "No bots match", "Set up voice",
  "Group conversation", "Transcript").
- The conversation picker matches its create entry against the translated
  label instead of a fixed German string.

The German wording returns through the de catalog in the next commit.
Unit and E2E tests now assert the English labels.

* feat(web): keep Lingui catalogs complete and in sync

The committed catalogs were last extracted weeks ago: about 330 source
messages were missing from every locale, and production builds keep only
message ids, so those strings rendered as hash ids (sidebar sections,
privacy settings, profile, timeline, ...). German also had 226 empty
entries, and every extraction rewrote the files because references carried
line numbers.

- lingui.config.ts: po references without line numbers, and a stable sort
  that breaks Lingui's ordering ties (explicit ids, equal text) by id, so
  the output no longer depends on file-system order.
- Re-extract all catalogs with --clean (drops 25-44 obsolete entries per
  locale; no existing translation changed).
- Translate every German entry (du form, consistent with the existing
  catalog). Other locales keep empty entries and fall back to English.
- i18n-catalog-sync.test.ts extracts into a copy of the catalogs and fails
  when the committed files differ or a German entry is empty, so stale
  catalogs fail the unit test job (offline, about 5 s).

Adds @lingui/format-po (already installed through @lingui/cli) as a direct
dev dependency to configure the formatter.

* feat(media): add the ComfyUI provider, default workflows and emulator

Image and video generation run on the user's own GPU server. ComfyUI is the
common self-hosted backend, so this adds a provider for its HTTP API that the
generation operations can call.

- Core: API-format workflow templates with a small placeholder format
  ({{prompt}}, {{width}}, {{seed}}, ...) that is validated and filled without
  evaluating anything. Defaults: text-to-image and image-to-image on core nodes
  for any SD-family checkpoint, and text/image-to-video on ComfyUI's core
  LTX-Video nodes; a README lists the placeholders and model files.
- Adapters: createComfyUiProvider submits a workflow, polls its history,
  uploads input images and downloads outputs through the address-checked fetch
  used for other self-hosted model servers, with timeouts, capped reads and
  readable errors. A custom workflow from settings replaces the default it
  matches. Cancelling dequeues or interrupts only its own prompt. GPU status
  counts memory ComfyUI can free for itself as available.
- Contracts: input schemas for generate_image, generate_video and edit_image.
- Tests: an in-process ComfyUI emulator, a provider-neutral generation
  conformance suite and provider tests, all offline.

* refactor(memory): derive the run's memory budget from the document limit

The prompt budget was a separate 32 KB constant; it is now twice the
per-document limit, so a full bot document and a full space document keep
fitting if either number changes.

* feat(profile): edit facts in place in About you

About you could only confirm or delete what the bots know about the user, so a
fact that was slightly wrong or filed under the wrong category had to be
deleted and taught again, and a fact could not be limited to some spaces from
the app even though the profile supports it.

- Each fact gets an Edit button that turns its row into an inline editor:
  wording, category, and (when the user has more than one space, or the fact
  is already limited) which spaces it shows in. Escape or Cancel leaves it
  unchanged; only changed fields are sent through profile.update editFacts.
- A limited fact names its spaces next to its source.
- The repository validates edits like new facts: a wording whose normalized
  form is empty or equals another fact of the user is refused, all edits of
  one update apply atomically, and the stored embedding is only dropped when
  the wording really changes.

* feat(inbox): list and answer items from all of the user's spaces

The inbox in the main conversation only showed asks, approvals, takeovers and
unread threads of the current space. The main conversation lives in the home
space, so anything a bot needed in a project space never reached it.

- inbox.list now covers every space the user belongs to (except spaces being
  deleted), still only the user's own bots, runs and threads. Items from
  another space carry that space's id and name.
- The web inbox shows the space name next to the bot for those items, answers
  them with that space's header so the existing thread procedures check
  membership and ownership for that space, and opens their thread in it.

* feat(coach): coach RPCs for goals, habits, check-ins, today and rhythm

The web app needs to show and change the user's coach data, and the
check-in times need a way to change after onboarding.

- coach.today, coach.goals.*, coach.habits.*, coach.checkIns.* and
  coach.rhythm.get/set, owner-only and not space-scoped; another user's
  ids read as not found, invalid input as a bad request.
- coach-rhythm reuses the shared clock-time helpers.
- Tests: an API suite covering ownership and validation for every
  procedure, the coach tools driven through the main bot (and refused
  for a specialist), and a morning check-in routine that fires in the
  main conversation and writes today's brief; the unauthenticated
  authorization sweep lists the new procedures.

* feat(onboarding): save goal, check-in rhythm, quiet hours and push from the cards

With the coach and notification modules merged, the onboarding answers now take effect:

- the goal card creates a goal (source onboarding) through createGoal;
- the rhythm card sets the main bot's check-in routines through setCoachRhythm, and the
  closing line names the first check-in from the routines that were saved;
- the quiet-hours card updates the notification settings;
- the choice card tells the server whether this browser can still turn push on, so the
  notifications card is offered only there, and "Turn on" subscribes before answering.

The thread lock becomes NO KEY UPDATE so a rhythm routine, which references the thread, can
be written while the answer holds the lock. The goal answer is capped at the coach title
length. A Postgres suite walks the questions end to end: answers, skips, a dismissed card, a
stale and a doubled answer, another bot's focus card, and another user's access.

* feat(media): stream artifacts over HTTP with Range support

Videos and audio can be hundreds of megabytes. Artifacts only travelled as
base64 inside RPC calls, capped at 10 MiB and held whole in memory, so media
could neither be uploaded, played with seeking nor produced by media jobs.

- ArtifactStore gains stat, createReadStream (inclusive byte ranges),
  putStream (size cap enforced while writing, real SHA-256) and an optional
  localPath so ffmpeg can read stored files in place. LocalArtifactStore
  implements them with the same safety as before (O_EXCL, O_NOFOLLOW, 0600)
  and now validates space ids and keys before building paths.
- storeArtifactStream / storeArtifactFromFile store a stream or a job's
  output file as an artifact row, with width, height, duration and parent,
  and remove the blob again if the row cannot be written.
- GET /api/artifacts/:id serves an artifact with Range/206/416, ETag,
  inline disposition for media and attachment otherwise (safe RFC 6266
  filenames), nosniff and same-origin CORP. Authorization matches
  artifacts.get: the owner's artifact of an active bot thread or group,
  with membership of the artifact's space (media elements cannot send the
  space header; an explicit header must name the same space).
- POST /api/artifacts takes a raw streamed body with the target and name in
  the query, authorized like artifacts.create, with the MIME allowlist and
  the per-kind caps checked from Content-Length and again while writing.
- The API CSP allows media from the app origin and blob URLs.
- Web: artifactUrl(artifactId) and uploadArtifactFile for the UI.

Tests cover the streaming store, range parsing, filename sanitizing, the
file helper, and a Postgres suite for both routes: ranges, caching, other
users, shared-space members, other spaces, archived threads, signed-out
requests and upload limits including chunked bodies.

* feat(media): media job runtime, media queue and media settings

Media operations (generation, edits, transcription) need a runner that works
outside the agent turn, keeps a card in the conversation current and never
lets two processes put work on one GPU. Operations land in later commits; this
is the runtime they register with.

- Background job `media.run { jobId }` on a named `media` queue. Jobs carry an
  optional queue: the Graphile publisher passes it as queueName and the
  in-memory driver runs each queue one job at a time, in order.
- `createMediaRuntime` implements MediaRuntime (capabilities, start, get,
  cancel) over a list of `MediaOperationRegistration`s and runs jobs:
  start validates the input, creates the job and posts the bot's media card in
  one transaction (idempotent per tool call through an operation key), then
  enqueues it. The runner claims a fenced lease (an advisory lock keeps one
  live lease at a time, so the GPU stays single even when the queue is
  bypassed), renews it while polling for cancellation, writes progress and
  outputs into the card, defers with backoff when the GPU is short of memory
  or the operation asks to wait, bounds deferrals, crash restarts and run
  time, always cleans the job's temp directory and always ends the card in a
  terminal state. With continue_after the starting bot is woken in the same
  transaction that ends the job (new run trigger `media`).
- The reconciler re-enqueues jobs whose enqueue was lost, whose runner died
  or whose wait is over; a job stuck behind a dead worker's queue lock runs
  outside the queue.
- Media backends are deployment-wide settings stored encrypted as the
  `media` IntegrationProviderConfig row: `loadMediaSettings` and
  `saveMediaSettings` with the same address policy as OpenAI-compatible
  servers (no metadata hosts, public hosts only when allowed, HTTPS when a key
  is sent), a saved key never follows the settings to another server, and the
  view never returns keys. Contract in contracts/media-settings.ts.
- `createMediaOperations` is the one list both the API and the worker build
  their runtime from (empty until the operations land), and media-tools.ts has
  the shared `continue_after` schema helper for the tool definitions.
- Migration: lease, deferral, operation key and continueAfter columns.

* test(notifications): cover quiet hours, delivery, nudges and the notification RPCs

The quiet-hours CHECK accepted a row with only one bound set, because a NULL comparison made
the whole condition NULL; it now requires both bounds explicitly. The migration has not shipped
yet, so it is corrected in place.

- Unit: quiet-hours math across midnight, time zones and daylight saving; VAPID key handling
  (configured, generated once and shared, invalid); the web push sender (encrypted VAPID-signed
  request, gone on 404/410, no private or non-https endpoints); the fan-out with fake senders.
- PostgreSQL: settings and subscription repositories (constraints, per-user removal, endpoint
  hand-over, device cap, concurrent nudge cap, cascade on account deletion), delivery and
  notify_user against a real main conversation, and every notification RPC through the API
  including cross-user isolation and endpoint validation.

* feat(web): notification settings, and sign-out stops this browser's push

Users had no way to turn on push for a browser, set quiet hours or opt out of nudges.

Settings gains a compact Notifications section: a switch for push on this device (only where
web push works: a secure context outside the desktop app), quiet hours with from/to times
(22:00-07:00 when first turned on) and a switch for nudges. Changes save in order as they are
made. A browser that blocked notifications says so instead of offering a dead switch. Logging
out unregisters the browser first, so a shared computer stops receiving the account's pushes.

The E2E stubs the Push API (headless Chromium has no push service), walks all three controls,
checks they survive a reload and captures the notification-settings screenshot.

* feat(media): transcription input, chunked transcripts and the Studio trigger

Groundwork for the transcribe operation and for creating Studio when it is
first needed.

- Contracts: TranscribeInputSchema (artifact id, optional language code).
- transcribeChunks uploads audio chunks in order and stitches them into one
  transcript on the original timeline; transcriptionChunkSeconds sizes
  16 kHz mono WAV chunks below the server's upload limit; transcriptSummary
  hands the bot the transcript, cut at a word.
- ensureStudioWhenMediaConfigured creates Studio once a media server
  (generation or transcription) is configured. Local edits alone do not
  count, because ffmpeg and image tools are present on most installs and a
  specialist nobody asked for would appear for everyone.

* feat(web): show media jobs as a live card in the conversation

Media jobs report progress and results through the media block, which the
web app did not render.

- MediaCard renders the block: operation icon, title, status (reusing the
  task card's labels, plus "Waiting for GPU" for jobs queued behind the
  GPU), a progress bar while active, the error when failed, and outputs:
  images as thumbnails with the existing lightbox, video and audio in the
  media player, subtitle and text files as file cards. Finished video and
  audio get a download link, "Export" with presets labelled by aspect ratio
  (the video's own shape left out) and "Transcribe", offered only when the
  space can run them; running jobs get "Cancel".
- MessageView renders it with one branch.
- An E2E seeds the card on a thread snapshot with real uploaded artifacts.
- artifact-url.ts and MediaPlayer.tsx are minimal stand-ins for the
  pipeline workstream's files and give way to them on merge.

* feat(media): edit and export video with ffmpeg

Bots can now cut, reframe and export videos for every common format without
a hosted service: ffmpeg and ffprobe from PATH do the work on the server.

- ffmpeg wrapper: PATH detection, ffprobe JSON probing (rotation, pixel
  aspect, frame rate, audio, packet scan when the container has no
  duration), runs with -progress parsing, abort and stall kills, an output
  size cap, partial-output cleanup and short errors without temp paths.
  Inputs go through the file protocol with the demuxer forced from the MIME
  type, so a crafted upload cannot be probed as a playlist that reads other
  files or URLs. extractAudio (16 kHz mono WAV) and renderPoster for
  transcription and media cards.
- A pure planner turns edit steps (trim, keep, concat, reframe, speed,
  volume, mute, subtitles, extract_audio, poster) into one filter_complex
  pass: leading cuts seek the input, appended clips are normalized to the
  frame, fps and 48 kHz stereo (silence where a clip has none), reframes
  crop, pad or blur to the presets, speed chains atempo, subtitles burn in
  from generated file names with a readable style that stays clear of the
  controls on 9:16 frames. H.264/AAC MP4 with yuv420p and faststart;
  location metadata is stripped.
- edit_video and export_video operations and tool definitions; the inputs
  are shared contracts so the media card can start exports.

* feat(media): stream job inputs and outputs, cover the job lifecycle on Postgres

Media files can be hundreds of megabytes, so the runner no longer buffers them:
inputs are cloned from the local artifact file when the store has one and
streamed otherwise, outputs go through storeArtifactFromFile (per-kind size cap
and MIME check while streaming; an oversized result fails the job with a short
card error).

A Postgres suite runs the runtime with fake operations: success with outputs,
posters and parent versions; input, availability, artifact and thread checks
before a job exists; tool-call replay; failure with temp-dir cleanup; outputs
outside the temp dir and sources of another user; deferral with backoff and its
budget; the GPU memory guard; cancel of a queued job and of a job running in
another process; one job per lease and one job on the GPU at a time; crash
recovery and its restart limit; reconciliation inside and outside the queue;
the continue_after wake; a cleared conversation; the run time limit; and
capabilities.

* feat(media): generate images and video on ComfyUI and edit images

Bots can now make images and short clips on the user's own GPU server and
rework images locally, through the media job runtime.

- generate_image: prompt, aspect preset or exact size, up to 4 images, optional
  source image for image-to-image. Sizes target what the default models are
  tuned for, and sources are fitted to that size before upload, so large
  photos cannot exhaust GPU memory.
- generate_video: prompt, aspect, duration up to 10 s, optional start frame.
- edit_image: crop, rotate, flip, resize to a size or format (crop, pad or
  blurred background), extend, convert, in that order, with sharp; an optional
  prompt repaints the result on ComfyUI. Edits keep the source as parent.
- Registrations declare the input artifacts so jobs refuse ones the user
  cannot read, and generation declares a fixed GPU memory floor (6 GB images,
  12 GB video) that a custom workflow cannot lower.
- Tool definitions reuse the operation input schemas plus continue_after.
- Saving media settings rejects custom workflows the provider could not fill.
- Tests: sharp edits on generated fixtures, handlers against the ComfyUI
  emulator, and a PostgreSQL suite running the operations through the media
  runtime (card outputs, artifact versions, foreign artifacts, GPU wait).

* feat(media): register video operations with the media runtime

edit_video and export_video now run as media jobs: both registrations join
the shared operation list the API and the worker build their runtime from,
name every artifact they read (source, appended clips, subtitle files) so
starting a job refuses artifacts the user cannot read, and their tool
schemas use the runtime's continue_after helper.

Container deployments get ffmpeg, ffprobe and the subtitle font in the
API/worker image. Tests cover the handlers against a fake job context:
cuts, blurred 9:16 reframes with subtitles, appended silent clips, audio
extraction, single frames, batch exports with posters and progress,
rotated phone video, clear input errors and cancellation. They skip where
ffmpeg is not installed; the planner and parser tests always run.

* feat(media): media tools, media RPCs and owner-only media settings API

Bots and users need to start and follow media jobs, and the deployment owner
needs to point the deployment at their GPU and transcription servers.

- Media tools are named like their operations. A run sees one only when the
  space can run that operation (MediaRuntime.capabilities); the per-bot
  allowlist still applies. applyTool hands every media tool to one
  dispatcher (media-tools.ts) that splits off continue_after, starts the job
  under the tool call's effect key (a replay returns the same job) and returns
  at once; refusals (invalid input, unknown artifact, unavailable) go back to
  the model as tool errors.
- media.jobs.start starts an export, transcription or image edit from a card:
  the conversation is resolved like every thread procedure, the card's bot
  (or the group's lead) posts the new card, and the runtime refuses source
  artifacts outside the actor's space. media.jobs.get and media.jobs.cancel
  only see the actor's own jobs.
- media.settings.get/update are deployment-owner only, never return keys and
  answer invalid URLs with a 400 that says what is wrong.
- createApp accepts media operations as a test seam.
- Tests: a Postgres suite over the RPCs (owner-only settings, encryption,
  key retention per server, URL policy, start/get/cancel isolation between
  users, card jobs end to end) and unit tests for tool exposure and dispatch.

* feat(media): transcribe audio and video into subtitles as a media job

With the media runtime in place, transcription becomes an operation like the
others: bots call the transcribe tool, the job runs in the background and
the card shows the subtitle files.

- createTranscriptionOperations registers transcribe: available when a
  transcription server is configured, refuses artifacts the user cannot
  read before the job exists, and writes <name>.srt and <name>.vtt next to
  the source (a .txt when the server returns no timings). With ffmpeg the
  audio is converted to 16 kHz mono WAV and long media is transcribed in
  upload-sized ranges on one timeline; without it audio is sent as stored
  and video is refused with a clear message. A server that is down or busy
  (unreachable, 429, 502, 503) defers the job instead of failing it, since
  nothing has been stored yet. The bot gets the transcript, cut at a word.
- The transcribe tool definition uses the shared media schema helper and
  continue_after; dispatch stays generic.
- The main bot's run creates Studio once a media server is configured,
  right before the specialist directory is built.
- Dictation: when the user's voice provider cannot transcribe (or there is
  none), /api/voice/transcribe uses the self-hosted transcription server,
  and the voice status reports server dictation so the web app uses it
  instead of the browser's speech recognition. A voice provider that
  transcribes keeps being used as before.

The payload, target and outcome types are shared by the Expo and web push senders, so they now

E2E also stubs the Notification permission (headless Chromium reports it as denied even when
granted), and the quiet-hours inputs are wide enough for 12-hour times.

* feat(web): play video and audio inline and stream uploads and downloads

Media sent in a conversation had nowhere to go: the composer capped every
file at 10 MiB and pushed it through a base64 RPC, video and audio blocks
did not render, and downloads decoded whole files in the page.

- Video and audio blocks play inline through MediaPlayer, which loads
  nothing until the player is near the viewport, sizes the frame from the
  block's dimensions (vertical clips stay within the column) and uses the
  poster when one exists. Files the browser cannot play fall back to their
  name with a download action.
- Images load straight from the artifact route; the lightbox gains a
  download action.
- File cards, the Markdown preview and downloads read from the artifact
  route instead of decoding base64.
- The composer accepts each kind up to its cap and names the computed
  limit when it skips a file; video, audio and anything above the inline
  cap upload as a raw stream, small files keep the inline RPC.
- MediaPlayer and artifactUrl are what the media card builds on.

Tests: MediaPlayer laziness, sizing and fallback, the upload helper, and an
E2E that uploads a tiny MP4 fixture (VP9, since Playwright's Chromium has
no H.264 decoder), plays it from the artifact route and captures
media-video-block, plus the image lightbox download.

Covers what the unit tests fake: the job starts from validated input with

and an artifact of another user is refused before a job exists.

* feat(media): disclose media servers in AI data sharing

Media tools and card actions send prompts, images, video and audio to the
deployment owner's ComfyUI and transcription servers. Like the embeddings
server behind built-in memory, those self-hosted endpoints are recipients in
the AI data-sharing disclosure: they appear with the model uses ("ComfyUI
(<origin>)", "Transcription (<origin>)", keyed by the full endpoint so a new
server asks again), and starting a card job asks for model consent on clients
that run the foreground check.

Also adds unit tests for the media settings store: URL normalization and
refusals, encryption, the key-free view, one decryption per saved version, key
retention per server and removing empty settings.

* feat(media): give agents attached media and larger bot files

Agents only received the documents of a turn on their computer and could
attach workspace files up to 10 MiB, so they could neither cut a clip a user
sent nor post the video they rendered.

- Current-turn images, video and audio are copied into the bot's workspace
  (Team Computers under bots/<botId>/) like documents. Remote computers move
  files as base64 JSON, so anything above their 12 MiB transfer cap stays in
  storage and the agent is told it by artifact id instead of failing the
  turn; local computers copy up to the kind cap.
- attach_file accepts video and audio by extension and attaches up to the
  kind cap when the store streams (still bounded by the transfer cap of a
  remote computer), stored through the shared artifact helper with a real
  SHA-256.
- The render_plot fallback that attaches a chart PNG now records the group,
  so the chart opens in group conversations.
- Agent history names image artifacts by id, like video and audio, so a
  later turn can refer to them.
- artifacts.get refuses files above 25 MiB: base64 reads hold the whole
  file in memory, and larger media is served by the artifact route.

* fix(mobile): show video, audio and media cards as plain rows

Mobile has no media UI yet, so video, audio and media-card blocks rendered

- Thread text and reply previews describe video and audio files and the
  media card's title and status.
- The bubble lists video, audio and a finished card's outputs as tappable
  rows that open the file like other attachments.
- Opening video or audio downloads it from the artifact route to the cache
  instead of a base64 RPC, so long recordings open without the server
  holding them in memory.

Uploads with a text/plain, text/csv or text/markdown body are CORS "simple"

deployment that relaxes it would accept uploads from any page. The route now
applies the same origin rule as CORS before reading the session.

* feat(onboarding): ask before discovering projects and let the user choose

The onboarding scan started on its own, discarded what it found, claimed
to read email and calendars, simulated progress for everyone who could
not scan, and its project creation always failed (wrong Space fields and
a space lookup by title across tenants).

Discovery now asks first and creates nothing without a choice:

- The scan step appears only for the deployment owner when
  ONBOARDING_SCAN_HOME is set; everyone else skips it. The simulated
  scan is gone.
- It shows the folder and asks. Only directory listings are read: git
  projects up to four levels deep, their languages and a few tools
  (Docker, GitHub Actions, Terraform). Symlinks are never followed and
  each chosen folder is resolved again before use, so nothing outside
  the folder is reached. Results stay with the account that scanned.
- Found projects are a checklist (none preselected); found languages and
  tools are facts (preselected). "Add" creates one project space per
  chosen project with createSpaceForMember and wireProjectWorkspace in
  the user's own organization, reusing the user's own space already
  linked to that folder, and saves the chosen facts as onboarding facts
  under the profile lock and fact limit.
- When a connection becomes connected (direct connect, authorization
  round trip, or catalog reconciliation), "Uses <App>" is remembered as
  a tools fact from the connector. Revoking keeps it.

The E2E harness now points ONBOARDING_SCAN_HOME at a fixture folder and
starts without a deployment owner, so owner-only onboarding steps appear
only in specs that take the seat through /__e2e/deployment-owner.

The card's follow-ups now reach the media job RPCs, and it only offers what
the space can run.

- media.capabilities answers which operations the actor's space can run
  (booleans only). The card asks once per minute per space, and only when it
  shows finished video or audio, so other cards cost nothing.
- Export and Transcribe call media.jobs.start with the card's message, so the
  same bot posts the new card; Cancel calls media.jobs.cancel. A refused
  start shows the server's message under the card.
- New files use top-level import type.

* fix(media): GPU guard for smaller cards, top-level type imports

- The GPU guard waited for free VRAM at the operation's floor even on a card
  whose total memory is below it (an 8 GB card and a 12 GB video floor), so
  such jobs deferred until their budget ran out. The requirement is now capped
  at 90% of the card's total; a card with less than half the floor fails at
  once with "The GPU does not have enough memory for this job."
- Tests pin that media tools reach a run only through the space's
  capabilities and within the bot's allowlist now that the image tool
  definitions exist.
- Type-only imports are top-level `import type` in the media runtime, tools,
  RPCs and tests (AGENTS.md).
- The ComfyUI settings test gives saveMediaSettings a store with nothing saved,
  since the save reads the previous settings before validating.

  the race are now observed and the grace timer is cleared with the job.
- Ending a job removes its temp directory when no runner in this process

  directories of jobs that no longer run.

* test(web): cover group uploads in the main conversation

The image E2E now runs in the main conversation, which is a group thread,
so the browser test covers group uploads and reads from the artifact route
as well as bot threads. Bot file attachments keep their run's operation id
for tracing, and the non-streaming attach cap is the inline cap directly.

* feat(media): title transcription cards with what they transcribe

A card that only says "Transcript" does not tell two transcriptions apart,
and it is English whatever the user's language.

- transcribe takes an optional title like the video operations, so a bot
  names the card in the user's language; "Transcript" stays the default.
- Transcribe on a media card passes the source file name as the title.
- The E2E seeds the card through bootstrap as well as threads/get, since the
  bot thread's first snapshot arrives with bootstrap.

* refactor(web): match the media player stand-in to the pipeline's props

The pipeline workstream's MediaPlayer takes artifactId, kind, name, poster
and size, without a MIME type; the card and the stand-in now use exactly
that, so its file replaces the stand-in without other changes.

* test(web): media settings E2E with the media-settings screenshot

The Media settings section (added in the previous web commit) lets the
deployment owner point media at their own servers: ComfyUI URL and optional
key, with the image model and custom image/video workflows folded under
Advanced, and a transcription URL with optional model and key. Saved keys are
never shown again; the key field says one is saved and offers to remove it.
Members who do not own the deployment do not see the section.

The spec fills both servers, captures `media-settings`, saves and checks the
exact update the server receives, then removes the saved key and the
transcription server; a second spec checks a member has no Media section.

* fix(media): disclose the transcription server before dictation uses it

Dictation falls back to the owner's transcription server when the voice
provider cannot transcribe, so that server is a voice recipient too: it is
listed for voice use (as "Transcription (<origin>)") whenever it would take
the recording, and not when the voice provider transcribes itself.

* fix(web): render media card outputs with the URL-based previews

The media pipeline moved image and file previews to the artifact route, so
they no longer take a bot or group target. The media card still passed one,
which no longer type-checks; only its follow-up actions need the target.

* fix(api): let large uploads finish and abort stalled ones

Node's default 5-minute requestTimeout cut off a 500 MiB video upload on
any uplink slower than about 14 Mbit/s, so the video cap was unusable over
ordinary connections.

- The API server's requestTimeout is 30 minutes, enough for the largest
  upload at about 2.5 Mbit/s. headersTimeout keeps its 60-second default.
- Each streamed upload aborts when the client sends no bytes for 60
  seconds: the route answers 408, the partial file is deleted and no row
  is written, so a slow-drip client cannot hold a connection for the full
  request timeout. Time spent writing to disk does not count.
- The store and the upload guard no longer wait for a body to confirm its
  cancellation, which a stalled or hostile client may never do.
- A guard test checks that every file the executor attaches records the
  thread's group, which the render_plot chart fallback once dropped.

* fix(media): use snake_case keys in every media tool input

The model saw edit_video and export_video with artifact_id next to
generate_image, generate_video, edit_image and transcribe with artifactId,
sourceArtifactId and negativePrompt. Mixed conventions in one tool list invite
wrong calls, so all media inputs now use snake_case like continue_after and the
other builtin tools: artifact_id, source_artifact_id, negative_prompt,
duration_seconds. Handlers, artifact checks, the media card's transcribe
action and the tests follow. Nothing has shipped, so stored job inputs need no
migration.

* fix(media): act on media cards in their own space, not the selected one

The main conversation lives in the home space, but the user can have another
space selected while it is on screen, and the card's actions sent that space:
media.jobs.start resolved the conversation in the selected space and failed,
and media.jobs.get/cancel only found jobs of the selected space.

The server now takes the space from the card itself. start finds the card's
message in one of the actor's own threads (the conversation named by botId or
groupId), requires the actor to still be a member of that thread's space, and
resolves the conversation and the source artifacts there. get and cancel find
the actor's job by id and require membership of the job's space.
media.capabilities takes an optional job id and answers for that job's space;
the card asks through its job and shares the answer per conversation. Every
other case is a 404, as before.

A Postgres test runs a card in the home-space main conversation while another
space is selected (start, get, capabilities, cancel) and checks that another
user and a user who left the card's space get 404 on every procedure.

This also completes the media settings section committed earlier as work in
progress (01eea83); its code was final, only that commit message said
otherwise.

* feat(onboarding): show the onboarding cards and check-in names in the user's language

The onboarding cards, the closing line and the coach routine names were English server text
for every user. The server keeps the state and an English fallback; the web now words them
through Lingui, so there is one translation source.

- Choice cards: the web says the question, the option labels and the placeholder from the
  step and option ids, and keeps the server text for anything it does not know (quiet-hour
  ranges are already written in the user's locale). Another bot's focus card is recognized
  by its option ids. Mobile and agent history keep the server text.
- The "Got it. … are a good place to start." line is gone: the app cards speak for
  themselves, and with no cards nothing is said.
- The closing line becomes an intake_note block (note "done", nextCheckInAt, English text).
  The web words it with the first check-in in the user's clock; mobile blockText and
  blocksToAgentHistoryText read its text through their generic fallback.
- Routines carry coachKey. The routine list and editor show a check-in under its label in
  the UI language until the user renames it; saving an untouched label keeps the stored
  name. The English names move to contracts (COACH_ROUTINE_NAMES); prompts stay English.

* fix(coach): move check-ins when the user's time zone changes

The coach check-ins are main-bot routines scheduled in the profile time zone, but a later
zone change (About you, onboarding, the main bot's update_user_profile tool, or forgetting
the whole profile) left them in the old zone until the rhythm was saved again, so they fired
at the wrong local time.

syncCoachTimeZone, next to the rhythm code, moves the main bot's coach routines that are not
in the current profile zone into it, recomputes the next run of armed ones and re-arms their
wakeup. Paused check-ins move but stay paused, routines the user made are never touched, users
without check-ins get none, and a save that leaves the zone as it is changes nothing. The
profile update and forget RPCs and the profile tool call it whenever they write the zone.

Quiet hours, the daily nudge cap and coach dates are evaluated in the profile zone when they
are used, so they need no migration.

* fix(web): word the main conversation preview in the user's language during onboarding

While onboarding wrote the main conversation, its sidebar row, project rows and Heute showed the
server preview: nothing for a pending card (a card has no text of its own, so the row fell back
to "Ready") and the English fallback of the closing note, even for a German user.

Groups now carry `previewBlock` next to `preview`: the latest message when it is an onboarding
card or note, validated with the same block schemas the messages use (now named exports). The
web words it with the helpers that render the card and the note, so no copy is duplicated: the
question while a card waits, the answer once given, and the closing note in the user's language
and clock. A dismissed card keeps the plain preview, as the conversation no longer shows it.
The field is left out for every other message, and mobile keeps using the plain `preview`.

The chosen-answer lookup moves from the card into onboarding-copy so the card and the preview
share it.

* fix(media): stream large media between the store and local computers

Attachments copied into a local computer's workspace were read whole from
the artifact store first, so a 500 MiB video sat in memory before it was
written to disk. attach_file did the same in the other direction: a large
file on a local computer was read whole before it was stored.

SandboxProvider gains optional readFileStream/writeFileStream. The desktop
(host workspace) provider implements them with the same path confinement
as its byte methods, one chunk in memory at a time, and removes a file
whose write fails or is aborted, including one that replaced an earlier
copy. The host-aware wrapper routes them, and providers without them
(remote computers, still capped at 12 MiB) receive the collected bytes.
Current-turn staging and attach_file now go through these helpers, and
unread streams are cancelled so the stored file is released. Media job
inputs stop copying when the job is cancelled.

The stream helpers move from the local artifact store into a shared
module so both use one implementation.

* feat(media): live ComfyUI progress over its websocket

A video generation runs a single ComfyUI prompt for minutes, and the media
card only advanced after each prompt finished, so it sat still until the
clip was done.

The ComfyUI provider now follows ComfyUI's standard /ws stream while its
prompts run and maps step progress to the job's overall fraction across
all prompts: never backwards, and short of each prompt's share until its
outputs are downloaded. The history poll stays the source of truth for
completion and errors; a socket that cannot connect, drops, or stays
silent leaves generation exactly as before, and it is closed on finish,
failure, cancel and abort. Each generation uses its own client id, so
concurrent jobs do not take over each other's messages.

The socket goes through a new createOpenAiCompatibleWebSocket next to the
guarded fetch: same URL and key checks, same resolved-address lookup,
ws/wss derived from http/https, the same Authorization header, a message
size cap, and a hard drop when a server never finishes the closing
handshake. It uses the undici package's WebSocket, so no dependency was
added. A provider given a replaced fetch without a matching socket opens
none, so tests and emulators never reach the network.

The ComfyUI emulator now serves the websocket and reports progress for
running prompts; provider, guard and conformance tests cover ordering,
multi-prompt mapping, unavailable and failing sockets, stray messages,
closing on cancel, and the address checks against a loopback server.
