# Desktop application export

`rea export-desktop-application <capture-folder> <directory>` turns a folder
written by [desktop application capture](desktop-application-capture.md) into an
agentenv bundle holding one computer app environment: the real application,
installed from the distribution archive, its vendor's apt repository or the
`.deb` file it was installed from on the `ubuntu-24.04` computer base, launched
at boot, seeded with the user's state and serving that state through agentenv's
data operations.

```sh
rea export-desktop-application ./mousepad-capture ./mousepad-bundle
agent-env run ./mousepad-bundle --dry-run
```

The export reads the capture and its [state view](desktop-application-state.md);
it does not run the application. `--name` sets the environment name; otherwise
it comes from the desktop entry id or the program, with an `app-` prefix when
that name would not be a portable bundle name (for example all digits). The
output directory must be new or empty. `--task` adds a task an agent wrote for
the capture, once REA has validated it against the capture; see
[desktop application tasks](desktop-application-tasks.md). `--package-url`
says where the computer downloads the package of an application installed from
a `.deb` file; see [Applications from a .deb file](#applications-from-a-deb-file).
`--seed-checkpoint` names the checkpoint whose state seeds the bundle, the
baseline by default, and `--end-checkpoint` the one a task must pass on, the
capture's last by default; see [The seed checkpoint](#the-seed-checkpoint).
`--synthetic-seed` says the seed was made for the task, as a build agent makes
it in a [build computer](desktop-build-witness.md), rather than taken from the
user's own data; see [A seed made for the task](#a-seed-made-for-the-task).

The command returns Evidence with operation `export_desktop_application` and
predicate type `rea.desktop-application-export`, listing the environment name,
the seed and end `checkpoints`, owned paths, seed files, the seeds it
rewrote to remove the capture host's name and user (`scrubbed_files`), the
gzip seeds it compressed again only to clear their headers
(`recompressed_files`), the bundle files that still hold them
(`unscrubbed_files`), and written files, the last four by their path in the
bundle. A failed export, cancellation
included, removes the bundle it had not yet published, so no partial copy of the
user's data remains. If the bundle was published but its output handles could
not be closed, the command reports a cleanup error that carries the export
Evidence; the bundle itself is complete.

The class file is `<name>_app.py` with hyphens as underscores, for example
`mousepad_app.py`: agentenv imports it under its stem, so a plain `<name>.py`
could shadow a standard library module such as `calendar`. A class name that
would collide with a name the module imports or defines, such as `Path`, takes
an `App` suffix.

The class declares:

- `Packages(apt=[...])` with the package the capture found. A vendor package
  is named `<package>/<release>`, its repository's release (the Suite apt
  reports as `a=`, or else its Codename), so apt takes it from that repository
  even when the Ubuntu archive offers a higher version or epoch, as noble's
  transitional `firefox` does over packages.mozilla.org's; it is named alone
  when the release names neither, or when the capture was written before
  releases were recorded. Its library packages follow, so a package that
  leaves out dependencies on the libraries it loads, as Typora's Electron
  package does, still starts; library packages the capture found neither the
  Ubuntu 24.04 archive nor a declared repository offers are left out, with a
  limitation, and so are those only repositories the export leaves out supply
  (a repository's `supplies`), such as one whose key the capture could not
  retain. An archive package's declared dependencies are trusted as they
  are. When the desktop entry's package is not the one that owns the program
  it runs, as `vim-common`'s entry runs `vim`'s program, the program's package
  (`executable_package`) follows the app's by name, since the entry's package
  need not depend on it; a capture that found no archive or declared
  repository offering it records why, and the export refuses it with that
  reason, as it does when only repositories it leaves out supply it, or when
  no package owns the program at all (`executable_package_reason` without
  `executable_package`). The package must come from the Ubuntu 24.04 archive
  or a mirror of it,
  or from a vendor apt repository whose signing key the capture verified and
  retained. A source counts as the archive when apt reports its origin as
  `Ubuntu` for a noble suite; a capture made before origins were recorded
  counts only Canonical's own archive hosts.
- For a vendor repository, `sources=[AptSource(apt=..., suite=...,
  components=[...], key="apt-keys/<name>.gpg")]`, with the retained key copied
  to that path (`.asc` when it is armored, which agentenv tells by its
  content). A PPA added with `add-apt-repository`, whose sources entry holds its
  key in `Signed-By`, exports that key as `apt-keys/<name>.asc`. apt takes one
  key per URI and suite, so sources that share them, such as one repository
  listed for two architectures, are declared once, with their components
  merged; one with a different key is left out. A repository
  whose key the capture did not verify, an Ubuntu Pro (ESM) repository, one
  whose sources entry's URI held a user name or password (which the capture
  did not record and the export never writes; the reason names neither them
  nor the URI), one not reached over http or https, or one whose `arch=`
  restriction leaves out the capture host's architecture is refused with its
  reason (a capture
  written before restrictions were recorded counts as unrestricted); when
  another usable repository lists the same version it is left out instead,
  with a limitation. The export also refuses snaps, flatpaks, AppImages, and a
  package no recorded repository lists unless it was installed from a `.deb`
  file the capture recorded and `--package-url` is given, since the computer
  could not install them by name, and a capture written before credentials
  were removed whose repository URI still holds them, since it counted that
  repository's libraries as installable; capture it again.
- `@computer_app(supports=...)` with both `amd64` and `arm64` for an archive
  package, which the archive serves for both, and only the capture host's
  architecture for a vendor package, since its repository may serve no other.
  A vendor package captured on any other architecture is refused. A package
  installed from its `.deb` file supports only that file's architecture.
- A launch at boot with the captured command, ready when a window of the
  captured class appears and one of them is listed in the taskbar and is not
  typed as a splash: a splash screen or a dialog of the class skips the
  taskbar or says it is a splash, and an app whose splash shows first would
  otherwise count as ready before its own window opens. Arguments that are the captured home or under it, and
  `<option>=<path>` values under it, are respelled under the computer user's
  `$HOME`. agentenv starts the app in its own folder, where an open or save
  dialog would show the framework's files, so the command first changes to the
  captured working directory (`"$HOME"` when that was the home, as for a
  desktop entry without `Path`), which a relative argument or program path
  such as `./app` also needs, and still starts if that folder is missing. The
  export refuses a capture that saw no application window.
- The seed's document, opened at launch, so the app shows it rather than its
  start screen: when the seed holds exactly one file the state view gives the
  `document` role, and the desktop entry's `Exec` takes files (a `%f`, `%F`,
  `%u` or `%U` field code), its path under `$HOME` is appended to the command.
  A command that already names a document, absolute or from its working
  directory, as one captured with `--argument <file>` does, is kept as it is;
  a settings path under the home does not count. A seed with no document launches
  as captured. With several, no desktop entry or an `Exec` that takes no file,
  the app launches as captured and the README and the result's limitations say
  why. A reset
  relaunches the app, so it opens the document again.
- For an Electron application (the capture found its fuse sentinel or a
  `resources/app.asar`), `--no-sandbox` right after the program unless the
  command already has it: Chromium's sandbox needs user namespaces the
  computer's container does not grant, and Electron exits without them. The
  README and the result's limitations say the sandbox is off.
- `paths`: the state directories holding the application's state files and the
  folders holding its documents, nested folders collapsed. A folder beside a
  state directory whose name differs from it only in letter case is owned
  whole in the files' spelling, so a `~/.config/GIMP` profile GIMP created
  during the capture beside the candidate `~/.config/gimp` is owned as
  `.config/GIMP`, not as the folder of its first file. The home itself and
  the shared `.config`, `.local`, `.local/share`, `.local/state` and `.cache`
  folders are never owned whole: a file directly in one is owned as itself.
  Files the capture recorded under a symlinked state directory's physical
  spelling are mapped back to the innermost such directory's home spelling,
  unless that spelling is outside the captured home, as when the home itself is
  a symbolic link. When a selected link names an application state directory,
  the bundle seeds the application's state path and restores the selected
  alias at boot. Selections nested under that alias are seeded under the same
  state path. An existing incompatible alias stops setup without replacing it. When two files map to one home path, the export uses the one present
  before the capture, else the first by path, and a limitation names the other.
- Data hooks, because declaring any hook switches off agentenv's default data
  plane: the class seeds the home once per boot and keeps it as the initial
  state with `keep_initial`, `data/add` and `data/reset` call agentenv's `add`
  and `reset`, and `data/get` returns the files under `paths` plus a data part
  with a typed JSON view of each, read in a worker thread. An application with
  no observed state declares no paths and no hooks.

A file under the owned paths whose bytes at the seed the capture did not
retain is not seeded: one in the state view without retained content at that
checkpoint, or one the capture omitted (for example too large or past the
content budget). The result lists them in `unseeded_files` and the README
names them. When the application held files open in folders whose starting
content the capture did not retain, a limitation names those folders, spelled
from `~/` under the home: a file there is seeded only when the capture
retained it, as it does one written during the capture, and the limitation
names the seed files there or says there are none. The desktop Trash,
`~/.local/share/Trash`, is never the application's, so a file the user moved
there is neither owned nor seeded, even when a window title names it; a
limitation lists the files the Trash held at the seed.

Files that changed during the capture outside the owned paths are neither
owned nor seeded, so the app starts without what it saved there: MuseScore
keeps its settings in `~/.config/MuseScore`, which its name rules miss, and
showed its first-run wizard on every boot. A limitation and the README name
those folders, leaving out desktop services' files, each collapsed to its
folder in `~/.config`, `~/.local/share`, `~/.local/state` or `~/.local`, the
hidden folder of the home it lies in, or else its own folder, up to eight and
a count of the rest. Capture again naming them with `--state-path`, or
`state_paths` on a build computer, to own them.

Lock files the app holds while it runs are left out of the seed: a copied one
makes the app find its profile or document in use, and a LibreOffice Calc
bundle whose seed held its profile's `.lock` showed no window at boot. They
are `lockfile`, `lock`, `.lock`, `.parentlock`, `parent.lock` and
`SingletonLock` anywhere, LibreOffice's document lock `.~lock.<name>#`, and
`*.lock` or `*.lck` directly in one of the application's state directories.
Elsewhere such a file may be a project's own, such as `Cargo.lock` or
`yarn.lock`, which pin dependencies, and is seeded, even under a folder whose
name starts with a dot. A file the state view makes a document, or one named
itself by `--state-path` or an absolute `--argument`, is never left out,
whatever its name. A limitation and the README list them, up to
eight and a count, after "Left out of the seed". They stay under the owned
paths, so `data/get` returns the lock the running app holds, and `data/reset`
restores the seed without them. Other seed files the app keeps for its own
running are seeded as captured and named, collapsed to the folder that holds
them: WebKit or Chromium storage (such as `hsts-storage.sqlite`, `storage/`,
`mediakeys/`, `Local Storage/`, `IndexedDB/`, `Cookies`), which may hold the
app's own data, and caches (a folder whose name ends in `cache`); a stale one
can change how the app starts.

The application's dconf keys at the seed, if any, are written once when the
app first starts, also for an application that owns no files, and the class adds
`dconf-cli` to its apt packages for that. The server starts before the
desktop's D-Bus session, so the class does not use `dconf load`: it dumps any
existing user database through a `file-db:` profile, then runs `dconf compile`
on that dump and the captured keys, in that name order so the captured keys
win, and replaces `~/.config/dconf/user`. If that fails, the server prints a
one-line warning and the app starts without the captured keys. `data/reset` does
not restore them. No file of the bundle holds them, so `data/get` does not
return them and no task check reads them; a draft whose only change between
its checkpoints is to the application's dconf keys says so with
`uncheckable_changes`, and one whose dconf database changed but could not be
read says so with `unreadable_changes`.

## The seed checkpoint

By default the seed is the state before the capture, its `baseline`, and a
task's end state is the capture's last checkpoint. `--seed-checkpoint` and
`--end-checkpoint` name others, so one capture can make a seed and then a
change: the user creates and saves a document and takes `checkpoint seed`,
then edits and saves it and takes `checkpoint end`. Exported with
`--seed-checkpoint seed --end-checkpoint end`, the bundle seeds the document
as it was saved at `seed`, owned paths, dconf keys and unseeded files
included, and a task must fail on that seed and pass on the state at `end`.
A file's state at a checkpoint is its last version recorded at or before it.
The export refuses a name the capture does not hold exactly once, and an end
checkpoint taken before the seed checkpoint; `inspect-desktop-application-state`
lists the names in `capture.checkpoints`.

## A seed made for the task

By default the seed is the user's real data: the README and the result's
limitations say to keep the bundle local and not publish it. With
`--synthetic-seed` they say instead that the seed was made for the task, and
to read `envs/<name>/seed/` before publishing the bundle; the export cannot
tell the two apart, so the flag is the caller's word. `export_build_environment`
passes it, since the building agent makes the seed in the build computer. The
Evidence records it as `synthetic_seed`.

## Host name and user

A seed can hold the capture host's name and the user's: Geany saved its mail
template as `pref_template_mail=ada@e81232be457d`, the user `ada` on a
container named `e81232be457d`, and many files hold the home path
`/home/ada`. The capture records `host.hostname` and `host.user`, and the
export removes them from what the bundle ships:

- In seeded text files (text, JSON, key files and XML in the state view), in
  UTF-16 files that start with a byte-order mark (keeping the mark, byte order
  and a following U+FEFF content character), and in the dconf keys,
  `user@host` becomes `user@localhost`, the
  host name standing alone becomes `localhost`, and the captured home becomes
  `/home/user` wherever it is followed by `/`, the end of the text, or a
  character that cannot continue a file name. The host name counts only as a
  whole name: not inside a longer word, before a `-`, or as a label of a
  domain such as `e81232be457d.local`, so a host named `ubuntu` leaves
  `ports.ubuntu.com/ubuntu-ports` alone. A host named `localhost` is left
  alone, but its `user@localhost` still takes the computer's user. The user
  name alone is never replaced, since a short one such as `ada` or `user` is
  also ordinary text. A rewritten seed is written with its own SHA-256, and
  `scrubbed_files` and the README list it.
- JSON and XML keep their syntax. In JSON only string values change, each
  read as its decoded value, so `\u0065` escapes cannot hide the host, and is
  written back as JSON only when it changed; numbers and `true`, `false` and
  `null` stay as they are even for a host named `true`. Member names are never
  rewritten, since `{"ubuntu": 1, "localhost": 2}` on a host named `ubuntu`
  would get two `localhost` keys and lose a setting; a file whose names hold
  the host is listed in `unscrubbed_files` instead. In XML only character
  data, attribute values, comments and CDATA change, character references
  decoded the same way; element and attribute names and processing
  instructions stay. A UTF-16 file is scrubbed by the format its text would
  have in UTF-8, so JSON or XML in UTF-16 follows these rules too.
- In the dconf keys only GVariant strings change, each read as its decoded
  value and written back in its own quotes only when it changed. Group names,
  keys, dictionary keys, bytestrings and everything outside quotes stay, so a
  host named `true` leaves `wrap=true` alone. A value whose string does not
  parse, or that holds an object path or signature, ships as captured.
- `SEED_HOME` in the class is `/home/user`, the home the seed spells, which
  the class respells to the computer's own home when it seeds the home at
  boot, as it did the captured home before. The replacements read as the
  computer's own: its user is `user`, with its home in `/home/user`, and
  `localhost` is the name every host has for itself.
- A gzip-compressed seed, such as a Gnumeric workbook, is decompressed, up to
  256 MiB, scrubbed as the format the state view read its document as, and
  compressed again whether or not its document changed, so no file name,
  comment or time its header held ships: with no file name, comment or extra
  field, modification time 0 and the operating system unknown, so the same
  document gives the same bytes on every host. It is deflated at the fastest
  level, or stored when deflating would make it expand more than the 100 times
  a view reads, so a seed that read still reads. It is listed in
  `scrubbed_files` when its document changed, and otherwise in
  `recompressed_files`, which the README counts rather than lists, so the
  example and template files an app copies on first run do not bury the
  document scrubbed; one already in that form ships as captured. The class copies it at
  boot as it is, so the home it holds stays `/home/user`. One that does not
  decompress ships as captured, its bytes searched, and one the state view did
  not read is only searched. One whose document needs no edit but a member of
  which has an extra field, where BGZF (`.vcf.gz`, `.bam`) and dictzip
  (`.dict.dz`) files index their blocks, also ships as captured, its bytes
  searched, so its blocks stay where its index says; one whose document
  changed is still compressed again as one member, losing them, as the
  export's limitation says.
- Binary files, SQLite databases among them, and text files over 256 MiB are
  copied as captured. Then every file the bundle ships, the class module with
  its dconf keys and the README included, is searched by a looser rule than
  the replacement's: the host name and `user@host` anywhere, as in
  `e81232be457d.local` or a seed named `e81232be457d-notes.txt`, and the
  captured home as a whole path, in its path and its content, JSON and dconf
  strings and XML references decoded and the replacements themselves set
  aside. Each one found is listed in `unscrubbed_files`, and in the README
  unless it is the README, to check before sharing the bundle. Bytes that are not text are
  searched as they are, so a binary file that holds the host in another
  encoding is not listed.
- A task check whose values name `user@host` or the host name anywhere, by
  that rule, is refused, as one naming the captured home is: the bundle does
  not hold them. Its field names, kind and id are not values, so a host named
  `file` or `kind` refuses no check. A task's checks must fail on the seed as
  the bundle ships it, scrubbed, so a check the scrub itself satisfies, such
  as a mail setting the user changed from `ada@e81232be457d` to
  `user@localhost`, does not count as failing there.

A capture written before the host's name and user were recorded has only its
home removed, with a limitation saying so; capture again to remove the rest.

## Applications from a .deb file

A closed-source application you installed from a `.deb` file you downloaded,
such as VariCAD from varicad.com, is not in any apt repository the computer can
use. Capture it with `--package-file` naming that file (see
[desktop application capture](desktop-application-capture.md)), then pass
`--package-url` to the export with an `http://` or `https://` URL the computer
can download that same file from:

```sh
rea capture-desktop-application --executable varicad --package-file ~/Downloads/varicad2026-en_2.03_amd64.deb --output ./varicad-capture
rea export-desktop-application ./varicad-capture ./varicad-bundle --package-url https://files.example.com/varicad2026-en_2.03_amd64.deb
```

The class then declares, beside `Packages`:

- `downloads=[Download(url=..., sha256=..., to="vendor/<file>", arch=...)]`
  with the captured file's SHA-256. agentenv downloads the URL once, when the
  bundle is put, and refuses the file unless its SHA-256 matches, so the
  computer installs exactly the captured version. The bundle does not contain
  the package.
- `Packages(apt=[...])` with the first alternative of each of the file's
  Depends and Pre-Depends entries, without version constraints or `:any`
  qualifiers, then the library packages the capture found, since a vendor's
  binary may load libraries its Depends leaves out.
- `run=[RunScript(script="install-package.sh")]`, a script the export writes
  into the environment folder. agentenv runs it as root from the app's folder
  once the apt packages are installed and the download is in place, with the
  network off: it runs `dpkg -i` on the download and then removes it.

The bundle supports only the file's architecture. Vendor sites often refuse
automated downloads, as varicad.com does, so the URL may need to point at a
copy you keep, such as a private mirror; you must be allowed to use that copy,
and the package's licence, such as a 30-day trial's terms, is yours to check.
The README and the result's limitations say so.

The export refuses a package no recorded repository lists when `--package-url`
is missing, saying to capture with `--package-file` if the capture lacks it. It
also refuses `--package-url` when the capture recorded no package file, giving
the capture's `package_file_reason` when there is one; when the archive or a
declared vendor repository installs the package already; when the URL is not
written as `http://` or `https://` or holds a user name or password; and when
the file is built for an architecture other than `amd64`, `arm64` or `all`.

## Grading once the app has saved

A task's verifier, `artifacts/<task>-check/verify.py`, grades the app's files
only once they have settled, because an app can save on its own timer after the
last change. Gnote saves a note 4 s after the last key, so a read taken as
soon as the agent stops finds the text on screen but not yet in the file. The
verifier reads the app's `data/get` every 0.5 s. It compares each file's bytes
between reads by their SHA-256, as `data/get` returns them, and grades once
every file has held for 3 s. The 3 s count from when a read returned the
current bytes, not when it began, so a slow read that brings a change late
does not count its own run as quiet. 15 s after the first read began, the
bound, the verifier grades the last completed read: no read starts at or
after the bound, and a read still running then is cut. Each result records
whether the files settled in `settled`, and whether the bound cut a read in
`read_cut`.

The window has a cost and a limit:

- An app whose files do not change during the check, such as one that saved
  at once, is graded 3 s after the first read returns.
- A save that lands more than 3 s after the first read returns is still
  missed. An app that saves 4 s after the last key is caught only when the
  agent stops at least a second after that key.
- Files the app rewrites more often than every 3 s, such as a log, never
  settle, so every check waits until the bound.
- The bound counts the reads too, so a slow `data/get` ends the check at
  15 s. Only the first read, which every grade needs, runs to its own
  timeout.

The bound and window are `SETTLE_BOUND_S` and `SETTLE_WINDOW_S` in the
verifier. `check_build_task` waits the same way before it grades each
witness stage; see [witnessing](desktop-build-witness.md#witness).

## Typed views

The views follow the [state view](desktop-application-state.md)'s formats and
shapes: SQLite tables (at most 64 ordinary tables, `tables_truncated` past
that, and per table `columns`, `primary_key`, at most 500 `rows` and
`truncated`, with blobs, unsafe integers and text that is not UTF-8 tagged as
REA tags them), JSON, XML as `{root, truncated}` with REA's node, depth and
whitespace rules and its `doctype` when the document declares one, key file
groups, text as
`{lines, line_count, truncated}` split on `\n` and `\r\n`, and zip archives
as their entries, read with Python's `zipfile` from the file in place, with
REA's entry, size, compression ratio and archive limits and its wording for an
entry it does not read. The module reads the central directory itself, as REA
does, and shows `zipfile` only the records it lists, reading each entry in
bounded chunks no further than a byte past its declared size. A gzip file is
the view of the document inside it, with `"compression": "gzip"` beside its
format, decompressed with Python's `zlib` within the same entry size and ratio
limits, its members joined as REA joins them. A JSON file
holding a number JavaScript cannot read exactly, such as an integer above 2^53,
or whose retained value nests more than 500 levels deep, gets an `error` instead of a view, as in
REA. Duplicate keys keep their last value before the depth check. Text that is not one JSON
document, such as JSON Lines, stays text. Format detection follows REA's
rules. Files larger than 64 MiB get an `error` instead of a view
and are not read. XML is read with Python's `expat` twice: with namespace
processing, which refuses what REA's parser refuses, such as an undeclared
prefix, then without it, so element and attribute names keep the prefixes the
document spells and namespace declarations stay attributes, as in REA's view;
text splits into nodes where REA's splits it, at CDATA sections, comments and
processing instructions. Both passes read a DOCTYPE as REA does: with
parameter entity parsing off, so the DTD it names is never read, and handlers
that refuse an internal subset, an external entity and an entity expat would
skip; the first pass also checks each start tag for a reference to an
undeclared entity, which expat drops from an attribute value without a word
when a DOCTYPE names a DTD. Known differences remain:

- dconf databases are reported as binary, since REA reads them with `dconf`;
  inside an archive, one is `dconf` with an error, as in REA.
- Zip entry names: a name in an Info-ZIP Unicode Path extra field is used only
  where Python's `zipfile` reads it (3.12 and later), and an entry whose local
  header names it differently from the central directory is damaged rather
  than read.
- SQLite databases are read in place, read-only, rather than from a staged copy;
  a write lock the running app holds is waited out for a quarter of a second
  and then gives the file an `error`, and so does a table or column name that
  is not UTF-8.
