What this changes

Eight commits, all one shape: something was reachable from a test and from
nothing else, or a document still described a file that no longer exists.
No UI change — every line this removes from lib/view/ is a symbol
nothing referenced.

Unreachable code, removed

  • PercentCircle — the app's only user of the circle_chart package, and
    nothing imported it. A reachability sweep from main.dart over imports and
    part edges found it as the only non-generated orphan in lib/.
  • vol_upload_prepare_script (sbm_parser::virt_manage) — a wrapper over
    VirtResourceOp::VolCreate; the upload flow runs vol_upload_command. No
    caller in the crate, the FFI layer, the monitor, or the tests.
  • globalAgentConversationScope — a chat scope constant nothing reads.

Production APIs only tests reached, removed

Each was reachable from exactly one place: a test file. The coverage moved
rather than went away.

  • oklch.dart: contrastRatio, hueDistance, relativeLuminance → private
    helpers in chart_series_test.dart.
  • firewall.dart: worstChange — the confirmation reads worseThan and
    admits itself (view/page/firewall/common.dart), and its test now covers
    those instead.
  • virt_resources.dart: VirtExternalIssue, virtSnapshotSupportIssue,
    virtPveStorageMaySnapshot. The snapshot form is offered or not on the
    host's own feature?feature=snapshot answer; a second, guessed rule beside
    a definitive one only added a way for the two to disagree.
  • intro.dart: introShowsVirt, introVirtFacts → the test drives the real
    intro and asserts the sentences a user is shown.
  • nav.dart: railWidth, a second name for _kRailWidth (which is
    NavRailMetrics.width by definition).
  • ask_ai_layout.dart: AskAiHistoryPresentation,
    askAiHistoryPresentationForWidth.
  • session_keep_alive.dart: isRegistered → its callers assert what the
    bookkeeping is for: a notice arriving, or never arriving.
  • motion.dart: AppMotion.debugPref → the test writes
    Stores.setting.motionPref, where the app writes it, and lets init()
    follow it.
  • local_files.dart: copyFileExclusiveForTesting and its reset → the test
    loads the real FFI library, which is what the import publishes through.
  • chart_series.dart: SeriesPalette.hueOf and the _hues it read → the
    test measures rendered hues — what a reader sees — instead of the hues the
    palette was built from.

FFI bindings removed (regenerated with flutter_rust_bridge_codegen 2.13.0)

  • script_segment_marker, custom_result_key: the app never builds a marker —
    sbm_parser generates the scripts. They moved to
    test/helpers/script_markers.dart, and were verified byte-identical across
    dotted and hostile keys before the switch. A hardcoded format is the point
    as much as the cost: if the separators or the encoding move, the fixtures
    stop matching.
  • command_specs was kept deliberately. It looks test-only, but the keys
    it answers are what disabledCmdTypes persists in the server table, so it
    guards stored data rather than a test.

Rust test helpers: gated, not deleted

stub_dir, run_sh, read, read_log_has and the PathBuf/Command/
Stdio imports are reached only from tests already marked #[cfg(unix)].
clippy therefore read them as dead and emitted six warnings on Windows, while
CI lints on ubuntu, where every one of them is called. Deleting them would
have taken the coverage with them; they are #[cfg(unix)] now.

Docs

  • docs/dev/virt.md described four paths the Virtualization tab deleted
    (lib/data/provider/pve.dart, lib/data/model/server/pve.dart,
    lib/view/page/pve.dart, test/unit/server/pve_test.dart) and two symbols
    that never existed. Replaced with the current layout.
  • The monitor-agent pages (en and zh) listed every grant but virt, which is
    implemented and gates three /bmc routes.
  • Four development pages existed but were absent from the Astro sidebar:
    monitor-agent, remote-desktop, theme-authoring, bmc.
  • The theme-catalog example pointed at a feature branch; the catalog is on
    main.

A test that could not fail, fixed

integration_test/android_rootfs_test.dart was 133 lines of debugPrint and
no assertion, so it passed whether proot ran the rootfs, refused it, or the
harness had staged nothing. It now asserts the result and the control: if
either of the two non-proot paths started working, proot would no longer be
the reason the rootfs runs and the test would be measuring nothing.

A regression CI caught

virt_tab_test.dart → "console text: in place, kept when left, taken up
again, closed", fixed in 740ba37b.

While rewriting this away from isRegistered(id) — which asked _entries,
and so answered true however the session was configured — I replaced it with
an assertion on the keep-alive notice. But a notice only exists once
remoteSessionIdleTimeout has elapsed, and this test left that at its default
of 0, which means "never". The assertion could therefore only fail.

The graphical case beside it already sets 60 for exactly this reason; this
one does now too. Worth flagging because my own Windows run passed it — the
timing differs there — and I had briefly concluded it was pre-existing on
main. CI's ubuntu shard disagreed, and CI was right.

How it was tested

  • flutter analyze lib test integration_test — no issues.
  • cargo clippy --workspace --all-targets — 0 warnings (main has six on
    Windows for those helpers). This compiles the whole workspace, monitor
    included.
  • cargo test -p sbm_parser -p sbm_ffi — green. cargo test --workspace did
    not finish on my machine: it runs out of page file building every monitor
    test binary at once, which is why the two crates this actually touches were
    run separately. CI runs the whole workspace on both ubuntu and windows.
  • flutter test test/unit (2768 passed) and test/widget (901 passed).
  • flutter_rust_bridge_codegen generate output inspected; the Dart and Rust
    content hashes agree (2022108223).
  • A note for anyone running the widget suite locally: an interrupted
    earlier run of mine left a truncated build/unit_test_assets (shaders
    half-written), which failed ~45 widget tests that have nothing to do with
    this branch. Deleting that directory and re-running fixed it. If you see a
    large, implausible pile of widget failures, check there first.

Two pre-existing Windows-local issues noticed on the way

Neither is fixed here, and neither shows up in CI — they are Windows only,
which is why the checks above are green.

  1. test/unit/rootfs/chsh_script_test.dart → "answers -l from /etc/shells
    when there is one". The temp path is handed to sh with backslashes that
    sh eats as escapes, so the fixture is written to a directory literally
    named CUsersAdminAppDataLocalTempchsh_script_test…etc in the repository
    root
    , and cannot be read back.
  2. test/unit/theme_bundled_test.dart → "serverbox.piggy is the store folder,
    byte for byte". Fails under core.autocrlf=true, which rewrites the binary
    .fsbt's \n to \r\n.

Native builds were not needed

The diff reaches crates/sbm_ffi/src/api/script.rs and its generated
frb_generated.rs, which is one of the paths that would call for
iOS Linux engine / macOS build / Windows build. They are not needed
here, on this evidence:

  • The two functions removed are plain #[flutter_rust_bridge::frb(sync)]
    wrappers — no #[cfg], no target_os, no platform-gated dependency.
  • Nothing on the native side referenced them: no match in ios/,
    third_party/, macos/, windows/ or hook/, and no symbol list or
    linkage check names them (scripts/check-ish-linkage.sh looks for
    _sbm_ish_*, libsqlite3 and internals, none of which this touches).
  • The library functions they wrapped (sbm_parser::script::cmd_marker,
    custom_cmd_marker, custom_result_key) are untouched and still used by
    the monitor and by script_compat.rs.
  • Rust tests (windows-latest) and (ubuntu-latest) both pass, which
    compiles sbm_ffi on the two platforms the native builds would use.

Checklist

  • make analyze and make test pass
  • cargo test --workspace passes, if anything under crates/ or
    monitor/ changed
  • No formatter was run over untouched code
  • make gen was run, if any model / ARB file changed — no model or ARB
    file changed; the FFI bindings were regenerated instead

Summary

Changes

  • Virtualization storage/network management scripts and FFI: Updates Rust resource operation validation, command/script generation and parser behavior for libvirt storage/network management and upload, with FFI exposure and expanded integration-style parser tests.
  • Application-wide Agent tools and local filesystem access: Changes target resolution/execution and bounded output/file handling for Agent tools, and introduces an app-owned local-files import path with safe legacy data copying.
  • Session expiry and keep-alive lifecycle: Updates the shared session idle-expiry state machine, including visibility, app lifecycle, changed timeout behavior, grace notices, and close-while-away handling.
  • Theme color and chart series palette: Adds OKLCH color conversion/gamut fitting and derives chart series colors from the active theme seed; removes the obsolete percent-circle widget.
  • Motion accessibility integration: Adds shared app/system reduced-motion state, Flutter binding behavior, MediaQuery propagation and platform accessibility refresh handling.
  • Firewall access and reachability analysis: Adds firewall access identity parsing and logic to classify whether firewall rules admit the app's SSH or monitor access.
  • Virtualization snapshot/resource models: Extends virtualization resource model helpers for snapshot trees, snapshots, storage, volumes, networks and related derived properties.
  • Navigation rail and tab layout behavior: Updates home navigation rail capacity, overflow routing, selection, settings access and navigation menu affordances.
  • Intro feature progression and virtualization onboarding: Refactors intro step applicability and adds virtualization feature onboarding while updating completion/version gating.
  • AI panel responsive layout: Introduces a width breakpoint helper for choosing side panel versus bottom sheet and tests its boundary.
  • Script marker test utilities: Moves script marker construction expectations into a test helper, decoupling tests from FFI-only marker functions.
  • Monitor agent documentation and site navigation: Updates documentation site configuration and English/Chinese development documentation for monitor agent capabilities, grants, access policy and transport behavior.
  • Virtualization developer documentation: Updates the virtualization development reference with implementation phases and detailed behavior/contracts for virtualization features.
  • Android rootfs integration probe: Adds a device integration probe verifying staged Alpine musl execution through proot and its loader on Android.

GT-610 added 7 commits October 3, 2026 16:57
PercentCircle was the app's only user of the circle_chart package and
nothing imported it: a widget kept alive by nobody, in a file the
reachability sweep from main.dart could not enter.

vol_upload_prepare_script wrapped VirtResourceOp::VolCreate for an
upload the app now runs through vol_upload_command; no caller in the
crate, the FFI layer, the monitor or the tests.

globalAgentConversationScope named a chat scope nothing reads.
stub_dir, run_sh, read and read_log_has, and the PathBuf/Command/Stdio
imports that go with them, are reached only from tests already marked
cfg(unix). On a Windows host clippy therefore read them as dead code -
six warnings - while CI lints on ubuntu, where every one of them is
called. Gating them says which host they belong to instead of deleting
the helpers those tests run on.
Each of these was reachable from exactly one place: a test file.

- oklch: contrastRatio, hueDistance, relativeLuminance. The palette's
  rules are stated in them, so they move into chart_series_test.dart as
  private helpers rather than leaving the module exposing arithmetic
  nothing ships.
- firewall: worstChange. Nothing called it; the confirmation reads
  worseThan and admits itself (view/page/firewall/common.dart). Its test
  now covers those, which is what the page actually asks.
- virt_resources: VirtExternalIssue, virtSnapshotSupportIssue,
  virtPveStorageMaySnapshot. No caller in lib, crates, the monitor or the
  tests but pve_backend_test.
- intro: introShowsVirt, introVirtFacts. The test now drives the app's
  own intro and asserts the sentences a user is shown.
- nav: railWidth. A second name for _kRailWidth, which is
  NavRailMetrics.width by definition.
- ask_ai_layout: askAiHistoryPresentationForWidth and
  AskAiHistoryPresentation. No history sheet ever asked for one.
- session_keep_alive: isRegistered. Its callers now assert what the
  bookkeeping is for — a notice arriving, or never arriving.
- motion: AppMotion.debugPref. The test writes the preference where the
  app writes it and lets init() follow it.
- local_files: copyFileExclusiveForTesting and its reset. The test loads
  the real library instead, which is the FFI call the import publishes
  through.
- chart_series: SeriesPalette.hueOf and the _hues it read. The test
  measures rendered hues — what a reader sees — instead of the hues the
  palette was built from.
The 'what is being migrated' section still named four paths the
Virtualization tab deleted: lib/data/provider/pve.dart,
lib/data/model/server/pve.dart, lib/view/page/pve.dart and
test/unit/server/pve_test.dart. It also pointed at pveProvider and
ServerDetailCards.pve, neither of which exists.

Replaced with the current layout — ServerTcpDialer for transport,
provider/virt/pve_backend.dart, model/virt/pve_resources.dart, the tab's
host picker, and the tests that actually cover it.

The snapshot note named virtSnapshotSupportIssue and
virtPveStorageMaySnapshot as the form's hints. Both are gone: the host's
own feature?feature=snapshot answer (and its refusal, which names the
storages) is what the view reads.

Also drop the theme-catalog TODO: assets/catalog/repos.toml is on main,
so the example no longer has to point at a feature branch.
The virt grant is implemented — permissions.rs, Grant::Virt (migration
011), and bmc.rs gates its three routes on it — and both monitor-agent
pages listed every other grant. A reader counting grants from the docs
would have found five and wondered which endpoints virt covered.

Four development pages were reachable only by link and absent from the
Development group: monitor-agent, remote-desktop, theme-authoring and
bmc. Added, with the Chinese labels beside the others. astro build puts
all four in every page's sidebar now; check-locale-parity still passes.
Every step was a debugPrint, so the test passed whether proot ran the
rootfs, refused it, or the harness had staged nothing — the three
outcomes it exists to tell apart.

Now: the rootfs unpacks (exit 0) and has a busybox; the control holds, so
a musl binary in the app directory runs neither directly nor through
Android's linker (if either started working, proot would no longer be
the reason and the test would be measuring nothing); proot runs
/bin/busybox and the marker reaches stdout; and a shell inside the
rootfs reads back an Alpine release and aarch64.
…lled

script_segment_marker and custom_result_key were reachable only from
test fixtures that have to look like a server's output. The app never
built a marker: sbm_parser generates the scripts, and the app reads what
comes back with parse_script_segments. So two functions crossed the FFI
boundary for the tests' benefit alone.

They move to test/helpers/script_markers.dart, which writes the format
out: <separator>.b64.<base64url name>, the same shape the parser
recognises. A hardcoded format is the point as much as the cost — if the
separators or the encoding ever move, the fixtures stop matching.

Verified byte-identical to the old bindings across names, dotted keys
and hostile ones before the switch. Bindings regenerated
(flutter_rust_bridge_codegen, 2.13.0). command_specs stays: it looks
test-only but the keys it answers are what disabledCmdTypes persists in
the server table, so it guards stored data (see frb_parser_test's enum
test).

📝 Walkthrough
  • Validate firewall port specifications: Port matching now accepts only a single port or exactly one complete range, so malformed separators and partial ranges cannot be mistaken for an allowed port. Tests cover malformed entries alongside valid ranges and comma-separated rules.

CI failure root-cause analysis

The Windows Rust CI job fails because the integration test the_endpoint_is_refused_when_full_access_is_off in server_box_monitor failed; all other listed test suites passed. The diagnostics do not include the assertion/panic details or enough context to identify why the test failed, so the underlying defect and triggering change cannot be determined reliably.

Verifiable fix

Inspect the full test output for the_endpoint_is_refused_when_full_access_is_off to identify its assertion and failure path, then correct the relevant endpoint/access-control behavior or Windows-specific test setup. Verify by rerunning cargo test -p server_box_monitor --test exec_api the_endpoint_is_refused_when_full_access_is_off on Windows, followed by the workspace test suite.

Incremental value: root cause, verifiable fix; confidence 48%. Passing CI ≠ absence of defects (§29.4).

Rewriting this away from isRegistered(id) - which asked _entries, and so
answered true however the session was configured - left it asserting the
notice with remoteSessionIdleTimeout at its default of 0, which is
'never'. No notice can arrive under that, so the assertion could only
fail.

The graphical case beside it already sets 60 for the same reason; this
does too now. Caught by CI's ubuntu shard, which is where the difference
from my own Windows run showed: the failure is timing-dependent.

…s probe

Two review findings, both in this branch's diff.

_importLegacyDocuments -> importFrom skips a name that already exists, so
a nested entry whose publish failed part way left a directory that no
later run would ever fill: importFrom saw the name, skipped the whole
subtree, and the entries after the failure were never imported even once
the cause was gone. The File case never had this - copyFileExclusive
removes what it wrote before reporting - and the Directory case now does
the same, taking back the subtree it just created. Destructive only of
this call's own work: dest was notFound a moment ago and app writers
await ensure(), which is waiting on this import.

The Android rootfs integration test unpacked into <support>/alpine - the
path a release before the linux/ container used - and deleted nothing,
so each run overlaid the last and the release and machine it read back
could be either run's. It now uses a name of its own under the same
directory (that legacy tree is not this test's to delete), unpacks into
a fresh tree, and removes it. tar needs -C's directory to exist, so the
create the assertions introduced alongside had also taken away is back.

Not fixed, and here is why: PoolCreate's rollback runs pool-undefine
only, so a pool-build that succeeded before a failed pool-start leaves
what the build made. Removing it is not a safe blind addition - for a
dir pool the target is a path the user typed (default
/var/lib/libvirt/<name>), which pool-build may have found already there
- and pool-delete refuses a directory with anything in it, so it would
either leave the storage anyway or delete a path this operation did not
create. The current answer is documented (docs/dev/virt.md, New pool)
and is what the Dart side tells the user; changing it is a behaviour
change that wants a decision, not a drive-by fix.

All three checked against the current tree. Two fixed in d2ff2455, one answered rather than changed.

1. Nested import could become permanently incomplete — fixed

Valid, and it is a regression I introduced by deleting the seam in 33ecec3b.

importFrom skips a name that already exists (local_files.dart:72-73), and
_publishNoReplace created the destination directory before publishing its
children. So a child that threw left the directory there, and every later run
saw the name, skipped the whole subtree, and never imported the entries after
the failure — even once the cause was long gone.

The File case never had this: copy_file_exclusive removes what it wrote
before reporting (crates/sbm_ffi/src/api/file.rs:27-30). The Directory case
now does the same — it takes back the subtree it just created, then rethrows
the original failure. Destructive only of its own work: dest was notFound
a moment earlier, and app writers await ensure(), which is waiting on this
import, so nothing else can have written under it. A failed rollback is logged
rather than swallowed, since that leaves exactly the state the guard exists to
prevent.

One honest note on testing it: I could not write a test that reaches the throw
with the current structure. _copy runs before _publishNoReplace
(:103-104), and a socket is skipped by _copy's Link()/default cases, so
the failure modes available to a test hit the staging copy rather than the
publish. I probed this — an added test passed vacuously, exercising nothing
— so I removed it rather than ship a test that asserts a fix it never touches.
The existing continues after one legacy entry cannot be copied is in the same
position. Reaching the branch needs a seam, which is what this branch removed.

2. PoolCreate rollback leaves built storage — not changed, deliberately

The observation is right: pool-build succeeding and pool-start failing
leaves what the build made, and the script reports only the rollback
(crates/sbm_parser/src/virt_manage.rs:389-397).

I did not add a pool-delete there, because I could not make it safe:

  • For a dir pool the target is a path the user typed (default
    /var/lib/libvirt/<name>, lib/view/page/virt/storage.dart:1118).
    pool-build creates it if absent but is equally happy if it already exists,
    so the script cannot tell "this operation made it" from "it was already
    there" — and deleting the second would remove a directory the user chose.
  • pool-delete refuses a directory that has anything in it, and these are
    typically non-empty. So the remedy would either leave the storage anyway (the
    reported symptom, unchanged) or, where the directory is empty, delete a path
    this operation may not have created.
  • The current behaviour is documented as intended, for both clients
    (docs/dev/virt.md:620, "a failed build or start undefines it again"), and
    the Dart side tells the user the pool is defined-but-not-started via
    VirtResIssue. So changing it is a behaviour change to a documented
    contract, not a drive-by fix — and it deserves your call on which answer you
    want (remove the storage, or report it as residual) before I write it.

Happy to implement either shape if you say which.

3. The rootfs test never cleaned up — fixed

Valid, and worse than reported: my rewrite in b9ae9c58 also dropped the
Directory(rootfs).create(recursive: true) that tar -C requires, so the
unpack could not have worked at all. -C into a missing directory exits 2
(verified locally: /usr/bin/tar: nodir: Cannot open: No such file or directory), and since the new assertion requires untar.exit == 0, the test
would have failed on every run.

The tree is now the test's own: .rootfs-proot-probe under the support
directory, unpacked fresh each run, removed by addTearDown, with the
create() restored. I did not clean up $files/alpine as it was, because
that path is not the test's — a release before the linux/ container unpacked
a real install there (aacc7d5e removed
_root = (await getApplicationSupportDirectory()).path.joinPath('alpine')),
and a device may still have a user's rootfs in it. Hence a new name rather than
a delete.

Rust tests (windows-latest) failed on the previous commit in
monitor/tests/exec_api.rs: a Timeout from the client at
the_endpoint_is_refused_when_full_access_is_off (:93). Unrelated to this
branch: monitor/ is byte-identical to main here, the same Rust passed
the run before, and the file fails locally on a different test in the
same file (the_configured_timeout_is_what_kills_a_command), then passes
twice in a row when re-run. The remote re-run needs admin rights this
account does not have, so an empty commit is the way to ask again.

portSpecCovers split an item on every : and - and read the first and
last numbers as a range, so 22:23:24 became start=22/end=24 and claimed
port 23. That is not a specification any host writes, and it is not one
firewalld or ufw would accept, but a stored or hand-edited rule is
whatever the file says — and this helper is what decides whether a rule
is read as admitting a way in.

Treating it as 22-24 has a rule that names nothing about 23 classified
as admitting it, which is the direction that matters: an unknown is
reported to the user as 'this may refuse', an open is reported as
nothing to worry about. So an item now has to be a port or exactly one
range, and anything else names nothing. A malformed item also no longer
hides the well-formed ones beside it in the same comma list.

The 1..65535 bound the same change added is not here: access.port comes
from FirewallAccess.fromSshConnection, which already refuses anything
outside it, so a bound could not change an answer.

Checked the four shapes the docs name still read as before (22, 80,443,
6000:6010, 6000-6010), and the firewall suites: firewall_test,
ufw_manager_test, firewalld_manager_test and firewall_page_test.

portSpecCovers and malformed multi-separator specs — fixed

Valid, and I reproduced it before changing anything. portSpecCovers('22:23:24', 23) returned true: the item was split on every : and -, and only the first and last numbers were read, so 22 and 24 became a range that swallowed 23. Same for 22-23:24 and 22:23-24.

Fixed in 04e12ba0. An item must now be a port or exactly one range; anything else names nothing, and a malformed item no longer hides the well-formed ones beside it in the same comma list. The direction matters here: an unknown is reported to the user as "this may refuse", while an open is reported as nothing to worry about — so reading a spec as a range it does not describe fails toward silence.

The four shapes the doc comment names still read as before (22, 80,443, 6000:6010, 6000-6010). I left out the 1..65535 bound I first added: access.port comes from FirewallAccess.fromSshConnection, which already refuses anything outside that range, so the bound could not change an answer.

Worth noting this is pre-existing, not something the branch introduced — my diff on firewall.dart only removed worstChange above it.

PoolCreate rollback — unchanged, and here is why

Reported twice; my answer is the same both times, so it is here rather than in two replies.

The observation is correct: pool-build succeeding and pool-start failing leaves what the build made, and the script reports only the rollback.

I did not add a pool-delete, because in this codebase that command is the user's decision, not a cleanup step. VirtPoolDelete.deleteStorage defaults to false, the UI only offers it when the pool is empty and pool.type != 'logical' (lib/view/page/virt/storage.dart:855-856), and it takes a deliberate tick in a confirmation dialog. Folding it into a rollback would delete storage on a path the user never asked to have deleted.

Three specific reasons it cannot be made safe here:

  • For a dir pool the target is a path the user typed (default /var/lib/libvirt/<name>, lib/view/page/virt/storage.dart:1118). pool-build creates it if absent and is equally content if it already exists, so the script cannot tell "this operation made it" from "it was already there".
  • pool-delete refuses a non-empty directory, and these are normally non-empty. So the remedy would either leave the storage anyway — the reported symptom, unchanged — or, where the directory is empty, remove one this operation may not have created.
  • The module's stated contract is about definitions, not storage: "a refused pool or network leaves no definition behind" (crates/sbm_parser/src/virt_manage.rs:7-9). Undefining is what it promises, and that is what it does.

The current behaviour is also documented as intended (docs/dev/virt.md:620, "a failed build or start undefines it again"), and the Dart side surfaces the outcome through VirtResIssue, so the user is told the pool is defined but not started rather than left to guess.

If you want the other answer — remove storage the build created, or report it as residual in the error — say which shape and I will write it. I did not want to change a documented contract on my own reading of a review note.
