Offer a fix that works when the file has no video to copy
Refusing "copy the video" for a file that has none built its one suggestion by hand — drop the video track and leave everything else alone. That is valid only when the audio axis already happened to be fine. For any audio the target cannot carry (Vorbis or PCM into MP4, MP3 into WebM) the offer is refused in the next breath, so the Advanced picker showed a one-tap fix leading straight to a second error. Nothing unsafe shipped — ConversionWorker re-validates — but it is a dead end, and it contradicted the promise Validation.Invalid makes in its own KDoc. Route it through the shared repair-and-filter path instead, as every other branch does. Excluding what the *user* asked for rather than the already-repaired spec is what keeps the case that worked working: an MP3 into MP4 still gets its copy offered, because the repair of a copyable track is that same copy. Only a branch that builds its own list can break that promise at all, since suggestions() ends by filtering on validate().isValid. The property test now covers both of them — this one and the image output — rather than reaching them by luck, which is how a dead-end chip survived two earlier widenings of it. Its failures name the probe too: three rows share a spec and differ only in the input. Closes #114 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Guard the whole Media3 export instead of only its two ends
transcode() posts its work to a HandlerThread, and everything on that thread has no caller to throw back to: an escaping exception reaches the thread's uncaught handler and takes the process down, while the continuation is never resumed. Both halves of that are bad, and the second is arguably worse — a worker left suspended forever holds a foreground service. The guarding was two narrow runCatching blocks, one around buildTransformer and one around transformer.start, with the two Media3 builders sitting unguarded between them. That gap was not theoretical. EditedMediaItem.Builder rejects a composition with both tracks removed, which is exactly what a plan of (Drop, Drop) asks for, and it does so with a plain IllegalStateException from the constructor. Validation now refuses the spec that produces such a plan, so neither the picker nor ConversionWorker will start one. Routing is a separate question and still answers Media3 for it — a dropped track makes nothing un-hardware-able — so a request that skips validation still arrives here: a job queued before the settings changed, or one made through ConversionWorker.request directly. CopyPlanner's own KDoc already names that path as the reason it re-checks what validation has checked; this is the same belt for the same braces. One guard around the whole body costs nothing on success and turns any such refusal into a failed job with a reason attached. The export body moves into startExport, whose contract is the thing that makes one guard enough: returning normally means the export is running and the listener owns the continuation, throwing means it never started and the caller does. Cancellation is still registered before start. Covered twice on purpose. Robolectric runs the real HandlerThread and the real Media3 builders, so the JVM test exercises the whole sequence and can be run anywhere; the instrumented one repeats it against the real framework. Neither asserts only that the failure is an IllegalStateException, because withTimeout raises TimeoutCancellationException and java.util.concurrent.CancellationException extends IllegalStateException — so that assertion alone calls an unresumed continuation a pass. Both were written that way first, and reverting the guard is what exposed it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Refuse a spec that would leave the output with no tracks at all
Validation already refused two ways of asking for an empty file: None on both codec axes, and Copy for a video track the input does not have. It missed the third, because it read only the spec. Name H.265 with the audio off, hand it an MP3, and the spec looks fine — it names a video codec — while CopyPlanner drops that track anyway, because the *input* has no video to encode. The plan is (Drop, Drop), the router still says Media3, and EditedMediaItem.Builder refuses to build a composition with both tracks removed. It refuses it on Transformer's own HandlerThread, where the user sees the app die rather than a reason. Asking the probe as well as the spec catches all three faces with one guard, and the equivalence is exact rather than approximate: CopyPlanner drops video for None or for an input with none, and audio for None, so "(Drop, Drop)" and this condition are the same set. A sweep over every non-image container by codec by codec against both probes asserts that, so a new container or codec cannot reopen the gap on an axis nobody wrote a case for. This newly refuses a combination the Advanced picker accepts today, and that is the point: today it crashes. What it must not do is refuse without a way out. The Copy face had one only nominally — its single hand-built suggestion was None + None, which validation rejects in the next breath, so the one-tap fix fixed nothing. All three faces now go through the shared repair-and-filter path, which for an MP3 into MP4 offers "copy the audio across" and nothing that has to be re-refused. Repair is also stopped from naming a video codec for a file with no video track. It used to fall through to the first codec the container could encode, so the fix offered for an MP3 was "H.264" — a codec CopyPlanner then drops, making the offer a fiction that happened to validate.

Notice if the release job loses the permission that lets it publish
build.yml's `release` job declares `contents: write`, and nothing checked it. Deleting those lines leaves actionlint clean and CodeQL silent -- a narrower permission is not an alert -- and the job is `if: startsWith(github.ref, 'refs/tags/v')`, so no pull request and no merge can exercise it. Measured with the declaration removed: every gating check still passed. The first thing that would notice is a release failing to publish, at the moment someone is trying to cut one. The deletion also looks like tidying. #106 has just put a top-level `permissions: contents: read` directly above it, so a reader could reasonably take the job-level block for a duplicate. It is an override, and a comment saying so is not a check. BackupExclusionsTest is the precedent: configuration rather than code, load bearing, and unguarded because nothing compiles it. The part worth reading twice is the second commit-worth of work in here. The test passed, and then the mutation that is supposed to redden it did not: BUILD SUCCESSFUL in 614ms Gradle cannot infer that a test depends on a file outside the source set, so the task stayed UP-TO-DATE and the test never ran. Under --rerun-tasks the same mutation failed it properly, which is the tell: the assertion was right and the wiring was not. A guard that does not re-run when its subject changes is not a guard -- it is a test that will be green on the day it matters, which is worse than no test because it reads as cover. Fixed by declaring the workflow as a task input. Verified the whole way round afterwards, without --rerun-tasks: mutate the file and the task re-runs and fails; restore it and the task re-runs and passes. What this pins and what it does not: it asserts the declaration exists in the release job's block. It cannot assert a release actually publishes -- that needs a tag push, which is the thing no PR can do. A tripwire against silent removal, not proof the path works, and the KDoc says so. Closes #107. |

Delete an assertion that could never fail, and say what guards instead
ConversionViewModelProbeFailureTest's pickedProbe() helper held:
val ready = awaitState(viewModel.state, "Ready with a probe") {
it is ConversionState.Ready && it.input.probe != null
}
assertNull("nothing here should reach a terminal failure", (ready as? ConversionState.Failed))
The predicate requires `Ready`. `Ready` and `Failed` are sibling subtypes of one sealed
interface, so `ready as? Failed` is always null and the assertNull could never fire. R26
filed this PLAUSIBLE on types read; it is measured now.
Flipping the line to assertNotNull failed 3 of the 4 tests in the class -- three, because
pickedProbe() has three callers, which is also why a dead line here was worth removing
rather than shrugging at: it read as coverage in a helper the whole class depends on.
Deleted rather than replaced. There is nothing for a live assertion to add: a pick that
ended in Failed never satisfies the predicate, so awaitState fails on its timeout naming
what it was waiting for -- "Ready with a probe" -- which is a better failure message than
the assertion would have produced. The comment now says that, so the next reader does not
re-add the guard the predicate already is.
This is the ninth vacuous assertion this line of work has turned up, and the pattern is
consistent: they hide in helpers, they pass, and they look like care. The suite is green
before and after, which is exactly the point -- deleting a dead assertion cannot change a
result, and if it had, the line was not dead.
Closes #35.

Hold the two claims the codec MIME tables only asserted in prose
Two reasoned decisions were sitting in comments with nothing under them. `AndroidDeviceCodecs.mimeFor`'s `COPY, NONE -> null` arm explains itself by naming a consequence at another seam: returning null is what makes `canEncode` answer true, because a copied or absent track places no demand on the hardware. #90 pinned the null; nothing pinned the answer. Put a MIME in that arm and a device with no matching encoder starts refusing stream copies — jobs that encode nothing — and the router hands FFmpeg a re-mux Media3 could have done. Asserted now against `forTesting(encoders = emptySet())`, with an H.264 refusal alongside so a `canEncode` that simply said yes could not satisfy it. The second is a whole table. `Media3Engine.videoMimeTypeFor` is `VideoCodec -> MIME` on the same axis as `mimeFor`, and until #85 and #87 widened both to `internal` no test could see them together. Each had per-arm coverage pinning its own answers, which is exactly the shape that cannot notice the two tables describing different codecs: change one arm and its own expectation together and both suites stay green while the device is asked about H.265 and Transformer is told to produce H.264. They do not agree everywhere, and forcing them to would be a regression, so the test sorts every codec into the three buckets that exist and asserts the fourth is empty. H.264 and H.265 must match. VP8, VP9 and AV1 are named by the device table and not by Transformer's, deliberately: `setVideoMimeType` rejects them so the router never asks Media3, while the device may genuinely own a VP9 encoder and `canEncode` has to answer about it truthfully. COPY and NONE are named by neither. Sorting rather than filtering means a convergence fails too, so moving the line requires saying so in the file. Audio has no partner — `AndroidDeviceCodecs` enumerates video MIME types only, so `audioMimeTypeFor` has nothing to cross-check against and a missing audio encoder is still discovered by failing rather than up front. Named in the KDoc as unfinished rather than left as an unexplained asymmetry. Closes #86 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Stop swallowing coroutine errors nobody asserted on
`drainEscapedCoroutineErrors()` cleared the collector at rule-construction time
with `runCatching { runTest {} }`, and discarding what it found was the whole
mechanism: it could not tell the one known deposit from an escaped error nobody
had asserted on. That traded a loud, misleading failure for a silent one, which
was acceptable only while exactly one depositor existed and the seam to remove it
did not.
The seam exists now, so the depositor is gone: the OOM is consumed by the test
that raises it. Every Compose class takes the v2 `createComposeRule()` directly,
and a future escaped error fails a test again instead of disappearing.
The two findings the drain's KDoc carried that outlive it: the v2 rule and the
non-v2 `StateRestorationTester` do interoperate -- the note now sits at the two
declarations that pair them -- and a drain could never have been a `@Before`
(the rule's `runTest` wraps it) or a `@BeforeClass` (Robolectric runs that
outside the sandbox classloader, where the collector is a different object).
Full JVM suite run twice in a row with the drain deleted: 373 tests, 0 failures
both times.

Give the pick a dispatcher, so an escaped error fails the test that caused it
`onInputPicked` hops to a hard-coded `Dispatchers.IO` inside a `launch` with no exception handler -- deliberate, because a real OutOfMemoryError should reach the thread's default handler and take the process down. On the JVM there is no such handler: kotlinx-coroutines-test installs a process-wide collector, once per classloader and never removed, which keeps the error and rethrows it at whichever `runTest` starts next. Every Compose rule is a `runTest`, so the OOM raised by `ConversionViewModelProbeFailureTest` failed some *other* Compose class, and which one moved between runs of identical, green code. Naming the dispatcher gives the throw somewhere to land. With the pick inline inside a `runTest`, the collector's callback belongs to the test that caused the error, so it is handed over and consumed rather than stored for a stranger. Both hops of a pick rather than only the probe, which is where this differs from the seam issue #66 sketched: leaving the metadata query on a real IO thread makes the coroutine resume on a main looper Robolectric leaves paused, and that bounce is exactly the asynchrony that made delivery unpredictable. That buys the assertion the test could not make before -- the real OutOfMemoryError instance, not an inference from a card that never filled in, which is also what a probe returning null looks like. Reverting the hop to `Dispatchers.IO` turns it red: "expected java.lang.OutOfMemoryError to be thrown, but nothing was thrown".

Name the format in the image-demuxer failures
Bare assertTrue/assertFalse report java.lang.AssertionError and nothing else, so the mutation that proves this test bites -- relaxing the _pipe suffix to a substring -- went red saying only that a line failed.

Give the Robolectric choice a reason that is still true
Two test classes justified using Robolectric by asserting that the alternative does not
exist:
AppRootRestorationTest "The instrumented tests cannot run on the development
host at all (see CLAUDE.md)"
OutputPublisherStagingTest "The instrumented suite cannot run on the development
host, so this is the only place [it] can be caught"
Both were true when written and stopped being true on 2026-08-22, when the segfault was
traced to SwiftShader's Reactor JIT against SELinux execheap rather than to the machine.
tools/local-emulator/run-e2e.sh has run API 33-36 here since.
The first one cites CLAUDE.md as its authority, and PR #73 corrected CLAUDE.md to say the
opposite. So it was no longer merely stale: a reader who followed the reference found the
contradiction, with the citation making the wrong half look verified. That is the worst
version of this -- R14, R15, R20 and R25 were all the same defect, and this is the fifth.
The choice itself was never wrong, which is why the fix is not to move these tests. Both
belong on the JVM, and the honest reason is cost rather than impossibility: neither needs
anything a device supplies, and both run inside the same ./gradlew invocation as every
other unit test instead of booting an emulator. That argument survives the correction; the
premise did not.
The old line also has a second failure mode worth naming. "Nobody can execute this" invites
a reader to skip the local run and let CI decide, which is the opposite of what the
definition-of-done in #51 asks for.
Verified: the string appears nowhere in app/src now, and testDebugUnitTest, ktlintCheck and
detekt are green.
Closes #46.

Make the two codec tables answer for each other, and stop describeAudio printing a NUL
The FFprobe codec vocabulary is written out in at least four places and none of them had a test. Two had already drifted apart. `x264`, `hev1`, `x265` and `vp09` resolved in `CodecNames.videoFromName` and returned null from `AndroidDeviceCodecs.mimeForCodecName`, so the app identified the codec for the source card and for routing and then ran the device capability check blind on the same string; `mpeg4` ran the other way and rendered as a raw name. Nothing could notice, and the reason is structural: a `when` cannot be enumerated, so no test can ask one table what the other one knows. Both are maps now, for that reason alone, and `CodecVocabularyTest` walks the two key sets. A name added to -- or removed from -- one side alone fails the build. The one legitimate asymmetry is listed rather than implied: `mpeg4` is decodable input with no `VideoCodec` to name it, so `CodecNames` is right not to carry it. That list is itself checked, because otherwise it is an escape hatch -- any future divergence could be waved through by adding the name to it, and adding `x265` to it now fails. THIS CHANGES BEHAVIOUR for `x264`, `hev1`, `x265` and `vp09`. A null from `mimeForCodecName` means "unknown to us: assume the platform can handle it and let a failed export trigger the FFmpeg fallback", which is the right policy for a name nobody recognises and the wrong one for a name recognised one file over. A device without the matching decoder now sends those four to FFmpeg up front instead of spending a doomed hardware attempt to discover it. No input loses hardware it could have used: each alias resolves to the MIME its canonical spelling already resolved to, so a device that has the decoder still answers true. `ConversionRouterTest` still passes and that is not evidence either way -- every `canDecode` in it is a hand-written stub that never reaches this table. #74 is the same family one level down. `describeVideo` answered "Unrecognised" for `InputProbe.UNPARSEABLE` and `describeAudio` had no such arm, so an unparseable audio codec would have fallen through to `?: name` -- and the sentinel opens with a NUL, so the source-info card would have rendered a `Text` beginning with U+0000. The two now share one body, which is what stops the next arm being added to one side only. Two corrections to that ticket, taken from the file rather than from the ticket, since it warns about exactly this: - It quotes `audioFromName` as opening with `null, InputProbe.UNPARSEABLE -> null`. It did not; it opened with `null -> null` and the sentinel reached `else`. Naming the sentinel in the shared lookup therefore changes no answer and is documentation, not the fix. - It says `describeVideo`'s arm has no test of its own. It did -- `descriptions stay readable for unknown and missing codecs` asserts it -- so deleting the shared arm now reddens three tests across both sides, not one. Mutations run, each on the full 386-test suite: add "avc3" to CodecNames only -> CodecVocabularyTest red on two counts, CodecNamesTest green: 8 tests, 0 failures, which is the ticket's point about per-table arm tests delete the UNPARSEABLE arm -> CodecNamesTest red on three, one of them quoting the NUL back add "x265" to DECODE_ONLY_NAMES -> CodecVocabularyTest red on the escape hatch delete "vp09" from the MIME map -> CodecVocabularyTest red on three, which is the state this commit is fixing Audio is not cross-checked, and that is a gap rather than a decision: the device capability check is video-only, so this module has no second audio table to compare `AUDIO_ALIASES` against. `Media3Engine.audioMimeTypeFor` is the other half and belongs to #85. `MediaProbe.shortName` (#84) is the fourth table and is untouched here for the same reason. Closes #87. Closes #74. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Check the MIME types Media3Engine hands Transformer, and the claim above them
Both tables decide what codec ends up in the user's file, and neither was exercised. Point H265 at VIDEO_H264 and every hardware HEVC export writes H.264 into a file the user asked to be H.265: Transformer does as told, the export succeeds, and the only symptom is a codec nobody chose. One arm carried an assertion rather than a value -- "Never reached: only an Encode plan consults this, and COPY/NONE are not Encode" -- which is a claim about callers parked in a branch of a callee. It is true, and nothing checked it, so it would have gone on reading as true after it stopped being. Proved instead: CopyPlanner answers both codecs before the Encode branch and its fallback draws from ContainerCapabilities.encodableVideo, which contains neither, so a sweep over every spec the planner can be handed asserts no Encode plan carries COPY or NONE. Counters guard the sweep, because `as? Encode ?: let` asserts nothing at all for a Drop or Copy plan. The audio sibling claim did not survive intact. "MP3 and FLAC have no Android encoder; the router routes them to FFmpeg" is true and incomplete: one rule, `audioEncode !in MEDIA3_AUDIO`, diverts Vorbis by identical logic, so three of the six encodable codecs never reach the table. VORBIS -> AUDIO_VORBIS is a correct mapping for a request Transformer is never given. The arm stays -- a right answer in unreachable code costs nothing -- and the comment now says so. The tables are asked of the router's decisions rather than of its codec sets, because the comments claim behaviour and a set can be right while the rule reading it is wrong. Both move to an internal companion object so a JVM test can reach them without constructing an engine, which would start a real HandlerThread to answer an enum lookup; #57's precedent, and the JVM test source set is a friend of main.

Test the three MediaProbe helpers nothing else would catch
MediaProbe's MIME table, its image-demuxer rule and its Int reader are pure
functions with no test at all, and each fails silently rather than loudly.
shortName falls through to substringAfter('/') and reports a plausible-looking
string that CodecNames may or may not still recognise, so a dropped arm turns a
stream-copyable file into a re-encode. isImageFormat is checked before anything
else in classify, so a wrong answer overrides both probes. intOr's runCatching
is the only thing standing between a Float frame rate and losing every other
track property the loop had read.
Widen the three to internal, as #57 did, and say in each KDoc why the shape is
what it is -- the _pipe suffix is not a substring test because yuv4mpegpipe is
raw video, and getInteger casts rather than coerces.
Every format name asserted came from ffprobe rather than from memory: a picked
.png reports png_pipe, a .jpg reports jpeg_pipe, a .y4m reports yuv4mpegpipe.

Ask each join state what it lets the user do next
`JoinScreenContent` decides the whole join UI in one `when`, and until R38.5 gave it a state
parameter nothing could ask it anything: `Waiting` follows a denied foreground start and `Joined`
follows a finished `ConcatWorker` run, so neither is reachable by driving a real `JoinViewModel`.
`JoinScreenContentTest` used that seam to prove it exists, on one state. This is the matrix behind
it -- seven states, each pinned to the affordance it offers and the callback that affordance is
wired to, asserting on the value handed back rather than on something merely having fired.
Two of the thirteen assert things nothing else in the suite has ever asked.
The rows are read back sorted by their position on screen and compared as an ordered list. A join
is the one flow where the order of the inputs is the content of the output -- the empty state
promises "in the order you want them" -- and `JoinLeafTagsTest` proves only that a row tags itself
with the file it shows, which a reversed list would satisfy just as well.
The progress bar is asserted to be indeterminate, not merely present. It carries no percentage on
purpose, because FFmpeg reports progress against one input's duration and that means nothing across
a concatenation; the converter screen's bar is determinate, so "there is a bar" is exactly the
assertion that would let a fabricated percentage land here unnoticed.
Three mutations, each reverted after:
- `Text(s.message)` -> `Text("")` in `Failed`: "a failed join renders the message it carries" fails
with `could not find any node that satisfies: (Text + InputText + EditableText contains 'The
second file has no audio track, so joining stopped.')`.
- `when (s.strategy)` -> `when (ConcatStrategy.STREAM_COPY)` in `Joined`: "a re-encoded join says
the files differed" fails on the copy for the branch that no longer runs.
- `s.inputs.forEach` -> `s.inputs.reversed().forEach` in `Ready`: the ordering test fails
`expected:<[join.fileRow:intro.mp4, join.fileRow:middle.mp4, join.fileRow:outro.mp4]> but
was:<[join.fileRow:outro.mp4, join.fileRow:middle.mp4, join.fileRow:intro.mp4]>`.
Test-only: no file under `app/src/main` changes, and no tag is added to `TestTags`, because every
string these states render is either already tagged or unambiguous as text. The typographic
characters in the asserted copy -- U+2026 in "Joining N files...", U+2014 in the `Joined` and
Paused lines -- were checked byte-for-byte against `JoinScreen.kt` rather than retyped; an ASCII
lookalike compiles and then quietly matches nothing.
Closes #63.

Say what each conversion state puts on screen, and what it withholds
The screen's state machine had a seam and no matrix behind it. Every arm of the `when` returns `Unit`, so an arm can render anything at all and still compile -- a button offered where it cannot work, a state's own data never reaching the node meant to show it, an affordance wired to the wrong callback. The leaf tests cannot see any of that: they compose `FileCard`, `AdvancedPicker` and the three pickers directly and never hold a `ConversionState`. The arm worth guarding most is `Ready`'s `enabled = validation.isValid`. The Advanced picker deliberately lets an impossible container / codec pair be selected, so that one expression is all that stands between an invalid spec and a job that cannot succeed. `enabled = true` compiles, renders an identical screen apart from one colour, and passed the whole suite before this. Callbacks are asserted over the complete log rather than one at a time, so a case reads "this one fired and nothing else". A bare "the callback ran" check stays green on an arm that fires the right callback for the wrong reason. The routing chip needed a tag to be locatable at all: its text comes from the finished job, so a text matcher would have to name a routing explanation the screen does not own. That is the only production change here. Not asserted, deliberately: `Failed`'s error colour, which Compose publishes nowhere in the semantics tree; and the three absent `FileCard`s, which are compile-guarded -- `Idle`, `Saved` and `Failed` carry no `input` -- so those lines state the intent without being what enforces it.

Give both screens somewhere for a state to come from
`ConverterScreen` and `JoinScreen` each inlined their whole `when (state)` inside the public entry point, and state arrived only as `viewModel.state`. That left four of the twelve state branches across the two screens with no test that could ever reach them: driving a real ViewModel needs a WorkManager and a media probe in the constructor, and even then `Waiting` follows a denied foreground start and `Converted`/`Joined` follow a worker run that has already succeeded. So the `when` moves into `ConverterScreenContent` and `JoinScreenContent`, which take the state, the settings, the validation and an actions holder. The entry points keep the three launchers and `collectAsStateWithLifecycle` and nothing else. The callbacks travel in `ConverterActions` / `JoinActions` rather than as loose parameters because detekt's `LongParameterList` sits at its default threshold of six and `config/detekt/detekt.yml` does not relax it for `@Composable` -- `AdvancedPicker` already sits exactly on it. Twelve flat parameters would turn a clean detekt run red; data classes are exempt from the rule. Nothing else changed. The body was cut and pasted rather than retyped, so the U+2026, U+2014 and U+00B7 characters the leaf tests match on are the same bytes, and `is Idle -> Unit` in the nested `when` -- permanently unreachable, and deliberately kept -- survives the move. The diff stops above `FormatPicker` in one file and above `FileRow` in the other, which is why the leaf suites #57-#60 landed pass unedited: every one of them composes a leaf directly and none references either entry point. The two new tests are the bite, one per screen and one per direction of the seam: a `Converted` / `Joined` state renders Save, and tapping Save hands back the name the finished job chose. The state matrix itself is #62 and #63. |

Say in tests what the file card says when it does not know
"Size unknown" is the line a stream fixing D5 reported as untestable. It is two assertTextEquals calls, and it needed two rather than one: the size line renders independently of the probe, so it is asserted with a probe and without one. That independence is the contract, and a test of the probed case alone would leave the branch a user hits first -- the card is on screen before the probe finishes -- unguarded. The rest of the card degrades in words the same way, and none of it was covered: the four InputKind branches, "No video track", "No audio track", describeVideo's "Unknown", and the two `> 0` guards that drop the dimension and length rows rather than printing 0 and 0:00. Each guard gets a case on both sides, because the present side alone stays green when the guard is deleted -- what deleting it produces is "Size: 0x0" and "Length: 0:00", the same invented-measurement defect as "0 B". The four pure helpers go in a plain JVM class beside it, with formatBytes pinned at each threshold and one byte below it. A `>=` quietly becoming a `>` is only visible from a value sitting exactly on the boundary. Two things the issue could not have known: - Its second acceptance criterion, "delete the return@Column and watch the Reading... test go red", cannot happen -- it does not compile. The early return is what smart-casts `probe` non-null, so ten uses below it fail with "Only safe (?.) or non-null asserted (!!.) calls are allowed on a nullable receiver". The exit is enforced by the compiler, not by a test. Both compilable regressions someone would land instead are covered and were run red. - CodecNames.describeAudio has no UNPARSEABLE arm, unlike describeVideo, so it answers the raw sentinel rather than "Unrecognised". Unreachable today, because the UNPARSEABLE kind renders the explanatory line instead of rows. Left alone; recorded on the PR for R38.5. The divider's absence is not asserted and cannot be: Material 3 renders it as a Box with no semantics modifier, so it contributes no node. What is asserted is everything it precedes, plus the card's child count. The class KDoc says so. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Hold the Advanced panel's gate, and the error card outside it
`AdvancedPicker` is the one leaf on the converter screen that carries its own state, and `ValidationError` is deliberately invoked after the `AnimatedVisibility` that gates the chip rows -- so an invalid spec explains itself and offers one-tap fixes while the section is collapsed. That is the only route out of an invalid spec for a user who never opened Advanced, it was completely untested, and folding the two `if` blocks into one is a plausible tidy-up that compiles. `AdvancedPickerTest` covers the gate in both directions, clicks each of the four colliding chip labels through its own row tag, and does every assertion about the error card with the toggle untouched. `AdvancedPanelSavedStateTest` is the `DestinationSaverTest` split for `expanded`: `StateRestorationTester` saves into an in-memory map, so it proves `rememberSaveable` is in use and nothing about the representation. Driving a real `SaveableStateRegistry` shows the picker saves the `MutableState` itself rather than the `Boolean`, which only survives a rotation because `mutableStateOf` on Android returns a `Parcelable` one.

Hold the three pickers to the constant they hand back
The format, quality and engine pickers are the same dozen lines with a
different enum substituted, and both ways they can go wrong are silent.
An onClick that closes over the picker's `selected` parameter instead of
the chip's own entry returns one constant for every chip; an inverted
`entry == selected` lights every chip but the right one. Neither throws,
neither changes the labels on screen, and a test that only asserted the
callback ran would pass over the first of them.
So each click test presses every chip in the row and compares the whole
recorded list against `entries`, which makes the constant load-bearing
rather than the click count, and each selection test asserts over every
chip rather than only the one that should be lit.
Verified by mutation, not by the suite going green:
- `onSelect(format)` -> `onSelect(OutputFormat.MP4_H264)` fails with
`expected:<[MP4_H264, MP4_H265, WEBM_VP9, ...]> but was:<[MP4_H264,
MP4_H264, MP4_H264, ...]>`
- `format == selected` -> `format != selected` fails both format
selection tests on `Selected = 'true'` for a chip that should not be
- `onSelect(preference)` -> `{}` fails with `expected:<[AUTO,
PREFER_HARDWARE, FORCE_SOFTWARE]> but was:<[]>`
- `selected.description` -> `QualityTier.FAST.description` fails the
quality prose test on the missing BEST line
Labels are read off the enums so a reword cannot redden this file for
the wrong reason. `EnginePreference` has no label of its own, so the
screen's own `label()` supplies that set. The one display literal with
no symbol behind it, the custom-spec line, was copied out of the source
byte for byte because it holds a U+2014 that would fail silently if
retyped.

Name the screen leaves, and give the tests a tag vocabulary
Kotlin `private` on a top-level declaration is file-scoped, so every leaf composable in the two screens was invisible even to the JVM test source set, which is a friend of main. The only three declarations src/test could name were ConverterScreen, JoinScreen and AppRoot -- there was nothing to write a test against, which is why #52 could not be started as filed. `internal` is the same choice MainActivity already documents for Destination: the unit tests can name it, and it stays invisible to anything outside the module. Eleven declarations in ConverterScreen and FileRow in JoinScreen. The tag table is the other half. Tests reference a symbol rather than a literal, which is what keeps the five children that follow independent: "Cancel", "Start over" and "Save file" are each rendered by both screens and by more than one state branch, so rewording one would otherwise redden several PRs at once and no diff would explain why. There were zero testTag, semantics or contentDescription calls anywhere in main before this. Every tag is applied inside main. A tag a test hands down as a Modifier proves only that the test set it -- it would survive the affordance losing its own tag entirely, which is the vacuous shape CLAUDE.md records nine of in one review. That is why FileRow and DetailRow derive theirs from data they already hold rather than taking an index from the call site. TestTags is public rather than internal, and R38.8 is the reason. It reads the table from androidTest, and whether that is a friend source set of main under AGP 9 had no in-tree answer -- nothing referenced a main internal from there. Settled by compiling one: it is a friend, so internal would work today. Public anyway, because that friendship is AGP wiring rather than something this project states, and the KDoc now carries the measurement so nobody has to repeat it. Smoke tests cover each leaf: it renders, and its tag resolves to exactly one node. Counting rather than asserting existence is deliberate, since a duplicated tag fails differently depending on which finder a later test happens to use. The state-branch tags -- Convert, Cancel, Save file, Start over, the progress bars -- have no bite yet: reaching a branch needs the state seam R38.5 extracts, and the state matrix is R38.6/R38.7 by design. Five mutations, all red on the named test alone: FORMAT_CHIPS deleted, FILE_CARD_NAME deleted, detailRow's tag no longer derived from its label, FileRow's no longer derived from its name, and JOIN_MORE given JOIN's value -- the last caught only by the uniqueness check, which is what it is for.

Drain the escaped coroutine error before the next test starts
`ConversionViewModelProbeFailureTest.an OutOfMemoryError is not swallowed` deliberately lets a real error escape `viewModelScope.launch`, which has no exception handler by design -- the ViewModel's KDoc says an OOM raised in the probe should reach the thread's handler and take the process down. On the JVM something else takes it. kotlinx-coroutines-test installs a process-wide collector for uncaught coroutine errors, keeps whatever it catches, and hands the backlog to the next `runTest` that starts, which throws UncaughtExceptionsBeforeTest. Every Compose test is a `runTest`: that is how `createComposeRule` runs a composition. So the error lands on an unrelated test in an unrelated file, and the message names neither the test that caused it nor the error's origin. Nothing has hit it yet only because the sole Compose test in the repo happens to run before the ViewModel one. R38 adds six more Compose classes in exactly the two packages that surround it, and the first two of them made the suite fail in two different files on two consecutive runs of identical, green code -- the throw is on a real Dispatchers.IO thread, delivered after the state assertion that ends the test responsible, so which class catches it is a race. Drain it where a Compose rule is built. A @Before cannot: the rule's `runTest` wraps the statement that calls it, so it has already thrown. @BeforeClass cannot either, because Robolectric runs it outside the sandbox classloader, where the collector is a different object. Constructing the rule is early enough, since JUnit builds a fresh test-class instance -- and every @get:Rule field on it -- before evaluating any rule. This is containment, not the cure. The cure is a seam: give the probe hop an injectable dispatcher the way the constructor already does for cleanupDispatcher, so the error has somewhere to land. That is a production change and deserves its own commit. kotlinx-coroutines-test was already on the unit-test classpath through compose-ui-test-junit4; it is declared now because a file imports it. Pinned, like robolectric and the linters: org.jetbrains.kotlinx is not one of the groups the prerelease guard covers, so a float here would be free to take a milestone.

Put a gate on the three pieces of wiring that had none
Three separate mutations passed the full 257-test suite, all for the same reason: the tool was tested and the thing that calls it was not. The join half of per-job staging. Reverting ConcatWorker to the constant the audit's own D8 table names -- "joined.<ext>", one string for every join of a format -- left everything green: PerJobStagingTest drives only the conversion worker, and StagingNamesTest pins only the pure function. The new case drives two real ConcatWorkers with different ids and reads what they asked for rather than what is on disk, because ConcatEngine is native, so neither join gets past it here and the catch on the way out deletes what it staged. The recorder moves into WorkerStubs, which is what that file is for, and the enum test that already had a private copy now uses it. The process-start sweep. Deleting the one line in LibreMediaConverterApp.onCreate() -- the only reason that class exists, and the backstop for every leak discardStaged cannot reach -- left everything green too. The test stages one file a day old and one written now, calls onCreate() again, and asserts both halves: the abandoned one is collected and the live one is not. The second half is what says this is a sweep rather than the clearStaging() it replaced, which could take a file out from under a running job. The mtime is set explicitly, because "written long enough ago" is not something a test can wait for when the period is twenty-four hours. Casting the Robolectric application to LibreMediaConverterApp is an assertion in itself: it fails if android:name ever stops pointing here, in which case the swept line would be correct code that never runs. The backup and device-transfer exclusions. Reverting data_extraction_rules.xml to the template's boilerplate left the unit tests green AND lintDebug green -- it is a resource, so nothing was reading it -- and the failure it causes is one nobody meets in development. WorkManager's queue is the app's whole backup payload, and its rows name content:// grants and cacheDir paths that do not survive a transfer; reattachment queries by tag on launch, so a fresh install would come up attached to a job the user never ran on it. The test reads the compiled resource table, so what it pins is what the APK carries, and it asserts domain and path for all four entries in both sections -- an <exclude> with no path is skipped unchecked by lint's own detector, so half an entry could protect nothing. Its KDoc records the one thing it does not cover: the manifest attribute that points the system at the file.

Clean up the empty document a refused open leaves, and stop the space sums wrapping
publish() opened the destination stream outside its guarded region, justified by "nothing has been written at that point, so there is nothing of ours to remove". That reasoning is wrong about what exists: SAF's CreateDocument contract creates the document before publish() is ever called -- which is why every fixture in OutputPublisherPublishTest starts as an existing empty file. A provider that then hands out no stream, because it dropped between the picker and the write or simply returns null, left a zero-byte file at the name the user chose while the screen said the save had failed. The open moves inside the try, so the same two bounds that already govern a failed copy govern this: only a document URI, and only a destination positively known to be empty. The dead-provider case is untouched and now demonstrably by the guard rather than by the placement -- nothing answers for that authority, so no size can be read, and "I could not tell" still refuses to authorise a delete. Its test comment said the old thing and now says that one. The space arithmetic overflows in two places, both live on main and independent of the allocatable-versus-usable question that stays parked: - hasSpaceFor computed `free > required + headroom`. A request within 128 MiB of Long.MAX_VALUE wraps that sum negative, and every free-space measurement beats a negative number, so the check answers "plenty of room" to the largest request it can be handed. Rewritten as `free - headroom > required` with both operands clamped at zero, which is the form the parked branch's StagingSpace.hasRoomFor already argues for. - InputQuery.total folded a join's inputs with nothing stopping the sum from wrapping, and that is the reachable half: no single file overflows, three four-exabyte inputs do. It saturates at Long.MAX_VALUE now, which the check above then refuses. SpaceArithmeticTest ties the two together in the shape the defect had -- the total that came out negative is handed straight to the space check -- and keeps one allowed case so the refusals cannot pass by refusing everything. The negative-size clamp is deliberately left unasserted, with a comment saying why: it only changes the answer when free space is below the headroom, which a test reading the host's real cache volume cannot arrange.

Stop three enum reads escaping doWork, and pin what the attempt bound buys
Both workers read enums out of their input Data with Enum.valueOf, and all three reads sit
ABOVE the try. A name this build does not define -- which is what a downgrade or a
rollback with work still in the queue produces, since WorkManager keeps work for about a
week -- threw IllegalArgumentException straight out of doWork(). That is D13's signature
verbatim: FAILURE with reschedule = false, output Data with zero entries so the screen
says "Conversion failed." and nothing else, and no staged.delete(), so the partial stays
in cache. readSpec() twelve lines below already handles exactly this case, and its KDoc
says why.
So all three take readSpec's shape: entries.firstOrNull { it.name == name } ?: default.
Consistency argues for it as much as correctness does -- the file already contains the
right answer to this question, three times.
WorkerEnumFallbackTest reaches each read. Two of them pin the value that replaces the
unknown name rather than only that nothing threw: a quality tier falling back to something
arbitrary would convert at a setting nobody chose, and a join's format decides the
extension its output is staged with, which is where FFmpeg infers the container from. The
engine-preference case asserts through the space check instead, because predicting which
engine AUTO picks would tie the test to a routing rule it is not about. Against the
unfixed code all three fail with "No enum constant ...".
MAX_FOREGROUND_START_ATTEMPTS had no test of its value. Both existing cases are written
against the symbol, which pins the relationship and leaves the number free: changed to 2,
the job gives up about ninety seconds after process death -- exactly the long conversion
the retry exists to protect -- and all 257 tests stayed green.
The new assertion is the property the KDoc argues, not the literal: summed against
WorkRequest's own DEFAULT_BACKOFF_DELAY_MILLIS and MAX_BACKOFF_MILLIS, the attempts have
to span at least eight hours, which is what makes "the user will have opened the app by
then" a claim rather than a hope. A deliberate re-tune that keeps the property passes; the
accident does not, and reports the span it got (0.025 hours at 2).

Test the edge that feeds reattachment, and stop it reporting ENOENT
Reattachment.choose has twenty tests and every mutation aimed at it bites. Everything that computes its inputs had none, and five mutations there passed the whole 257-test suite. Four are closed here, each verified by applying the mutation and watching the new test go red. jobSnapshots() is the half that has to touch WorkManager and the filesystem, so it is where the untested values live. JobSnapshotsTest drives it against a real WorkManager and a real cacheDir: - A zero-byte staged file is not an output. Relaxing the filter to `exists()` -- which is what a job killed before its engine wrote anything leaves behind -- made the snapshot claim a result, and the user would meet a Save button for a zero-byte "conversion". The same case pins that the path is still reported and that the mtime stays 0 for a file that is not a result. - Each result carries its own file's mtime. Hardcoding it to zero starves the newest-file tie-break of the only data it has, which is precisely the failure the tie-break exists to prevent: the query has no ORDER BY, so an arbitrary winner keeps winning every launch. Timestamps are set with setLastModified and compared against what the filesystem stored, because mtime granularity is not this test's claim to make. ReattachGuardsTest covers the two decisions the ViewModel makes that the pure rule cannot: - A file picked while the query was still in flight is not reattached over. Deleting the guard turns the user's pick into yesterday's job -- with the Save button pointing at a file the card does not name. Made deterministic by holding WorkManager's task executor rather than by racing two IO hops: the query cannot finish until the pick has landed. The test also asserts the brake really gripped, so a reattachment that never arrived cannot pass for one that was refused. - An Ambiguous result is offered without being attributed. Two finished jobs naming one staged file is what the device produced before staging was keyed on the job id; taking the first job's tags labels the file with the other conversion's name, which is the confident lie the KDoc rejects. The neutral label and the absent size are both pinned. ReattachmentTest's FAILED exclusion was only ever tested with pathless FAILED jobs, so a narrow regression ranking a FAILED job that carries a file like a result passed all 257 tests. The live shape is the 2 MB orphan the device pass found: a job killed mid-write leaves a partial, and under that regression the user is offered a truncated file with a Save button. One fixture with outputPath and outputExists set closes it. save() re-checks the staged file, in both ViewModels. The check reattachment made ran inside a tag query that can be hours older than the tap, and cacheDir is what the OS empties when it wants space and what the sweep collects after a day. The file's absence used to arrive as staged.inputStream() throwing, and e.message put "/data/user/0/.../4b4882....mp4: open failed: ENOENT" on screen -- a true statement about a path the user has never seen and cannot act on. It now reads as a sentence with an action in it. The message is one constant next to OutputPublisher because both ViewModels need it and staging is what it is about. Reattachment's KDoc claimed a defect that was fixed in the commit before it -- that "Start over" keeps its staged file -- which would send a maintainer to re-fix D2. Rewritten to say what is actually true: the delete happens, and the gap it leaves is the reset() whose delete is cancelled with the Activity, which is the sweep's job and is named in the sweep's own KDoc.

Let WorkManager keep sole ownership of the progress notification
`publishProgress` posted with `NotificationManager.notify(NOTIFICATION_ID, …)` directly, on the
very id WorkManager owns through `setForeground`, using a notification built `setOngoing(true)`.
Two posters for one id is a race about which of them wrote last, and on a Pixel 10 Pro XL it was
lost on attempt 3 of 12 while cancelling a `BEST`-tier job:
attempt 3: terminal state = CANCELLED
attempt 3: +300ms active=0 id1001=false ongoing=null <- WorkManager tore it down
attempt 3: +700ms active=1 id1001=true ongoing=true <- a progress tick put it back
attempt 3: +5000ms active=1 id1001=true ongoing=true
Still there ten minutes later, with no app process left in the world to withdraw it. The orphan's
record carried `flags=ONGOING_EVENT|ONLY_ALERT_ONCE` and **no `FOREGROUND_SERVICE`**, which is
what identifies the poster rather than merely suggesting one: WorkManager's own post goes out
with that flag and this one did not.
Whether the user could then swipe it away is deliberately not claimed here. An earlier reading
said "cannot dismiss", on the strength of `isClearable()` returning false — but that is false
purely because `FLAG_ONGOING_EVENT` is set, the record carries neither `FOREGROUND_SERVICE` nor
`NO_CLEAR`, and API 34+ lets an ongoing notification with no foreground service behind it be
swiped. The SystemUI test was impossible behind a secure lock screen and was never done. The
resurrection is what is reproduced, and it is what this fixes.
Progress now goes through `setForegroundAsync` — the non-suspending half of the same call
`doWork` already makes, which is the supported way to update a running worker's foreground
notification. That is not merely a different mechanism for the same post: it hands the id back to
its owner, so the notification WorkManager withdraws when the job ends is the same one the last
progress update wrote, and there is nothing left holding a second reference to it.
Two guards, and they are independent on purpose:
- **`isStopped` short-circuits the whole function.** A tick arriving after the stop has nobody
left to report to, so a stopped worker publishes nothing at all — the `setProgressAsync`
included, which WorkManager refuses for finished work anyway.
- **`setForegroundAsync` refuses on its own** for work whose state is already terminal. That
closes the window between the `isStopped` check and the update reaching the task thread,
which a check alone can only narrow.
The `~1/sec` throttle is unchanged, in effect and in reason: FFmpeg's statistics callback and
Media3's progress polling both fire several times a second, and pushing every one of them janks
the system UI. Routing them through WorkManager does not make them cheap, so the interval stays
exactly where it was. It is reordered into an early return rather than a nested `if`, which is
the only difference.
The initial `setForeground(...)` in `doWork` is untouched and stays a suspending call inside the
`try`. That placement is the whole of the previous commit on this file: a denied background
foreground-service start throws there, and `FailureOutcome` turns it into a retry rather than a
terminal failure. Converting it to `setForegroundAsync` for symmetry would have moved that
exception into an unobserved future and undone it silently.
The future `publishProgress` gets is not awaited — it is called from an engine callback, which is
not a coroutine, and a progress update is not worth blocking one for. Both of its failure modes
are benign, so a refusal is logged rather than propagated: dropping it entirely would make the
one that actually happens, a job finishing mid-update, invisible.
`ProgressNotificationTest` drives the real worker with a recording `ForegroundUpdater` — the same
seam `DeniedForegroundStartTest` uses — and asserts on both halves, because either alone passes
against something wrong. The positive half is that the update reached WorkManager on the id it
already holds, carrying `Notification.EXTRA_PROGRESS` of 42; a test that only checked nothing was
posted directly would pass just as well against a `publishProgress` that had been deleted. The
negative half is that Robolectric's notification manager holds nothing at all, asserted over the
whole manager rather than one id, so a renamed constant cannot make it pass by asking about a
notification nobody posts.
All three were red before the change: `one throttled progress update expected expected:<1> but
was:<0>` (nothing had reached WorkManager), `and must resurrect nothing expected:<0> but was:<1>`
(the device's resurrection, on the JVM), and `50 ticks inside one throttle window must not be 0
updates`. Each guard was then removed on its own to check the test that names it bites: without
`isStopped` the stopped worker publishes twice — `a stopped worker must publish nothing
expected:<1> but was:<2>` — and without the throttle fifty ticks become fifty updates.
`ConcatWorker` reports no progress at all and owns id 1002 by itself, so it has none of this and
none of it is added.

Tell an unknown input size apart from an empty file
`queryFile` started at `var size = 0L` and only moved off it when a provider answered the
`OpenableColumns.SIZE` column, which the platform documents providers *may* omit. So "this file
is empty" and "nobody would tell me how big it is" reached `OutputPublisher.hasSpaceFor` as the
same number, and `hasSpaceFor(0)` is not a space check -- it is "is there 128 MB free", which any
phone with a working camera passes.
The reachable value is not an inference. On a Pixel 10 Pro XL, `contentResolver.query` on a
`file://` URI returns null outright, so the cursor block never runs at all and the default
survives untouched: `queryFile gave displayName='input' sizeBytes=0`. Robolectric reproduces that
exactly -- null query, and a descriptor that reports 4321 bytes for the same file -- which is why
every test here is a JVM test rather than a device one.
`InputQuery` replaces the two copies of `queryFile`, which were byte for byte identical in
`ConversionViewModel` and `JoinViewModel`, so a fix to either would have been a fix to half the
app. It asks for the size twice: what the provider says, and then what the file itself says
through `openFileDescriptor(uri, "r").statSize`. The second needs no cooperation beyond the input
being openable, which a conversion is about to require anyway, and it is what answers the device
case above. Only when both decline is the answer null, and `InputFile.sizeBytes` is `Long?` so
that null cannot be spelled the same way as zero again.
**What an unknown size does was the decision, and it is deliberately not a refusal.**
`OutputPublisher.hasSpaceForUnknownSize()` produces the same number the defect produced by
accident -- with no size to reserve for, the headroom is all there is left to check -- and that is
worth saying plainly rather than dressing up. What changed is that it is now the answer to a
question that was asked. `hasSpaceFor` means "there is room for this many bytes" and nothing else
claims it.
Refusing was the obvious alternative and would have been worse than the bug: it turns "no
provider answered the SIZE column" into "this file cannot be converted", for a user who can do
nothing about either. A fixed floor was the other, and there is no honest number for it -- a
1 GB floor refuses a 10 MB conversion on a device with 500 MB free, which is the same failure in
a costume. `SpaceCheckTest` pins the choice from both sides: an unmeasurable input must not end
the job, and a full disk must still refuse it.
That second half is why the default answers *through* `hasSpaceFor`. `FakeFailures.FullDisk` in
the instrumented suite overrides `hasSpaceFor` and nothing else, so the delegation is the only
reason it still refuses an unknown-size job. Replacing the delegation with a bare `true` leaves
the full-disk test red with `expected:<Failure {error : Not enough free space to convert.}> but
was:<Failure {error : FFmpegKit failed to start on brand: robolectric...}>` -- the job sailed past
the guard and died at the engine instead.
Both workers get the same shape. The size arrives as input `Data`, which has no null, so the
absence of the key *is* the unknown -- `getLong(key, 0L)` was the other half of the conflation.
When it is absent the worker measures the input itself, which it can do because it holds the URI:
that covers a `request(...)` built by hand and work enqueued before the size became optional, and
it costs an ordinary job nothing because it runs only on the fallback. `ConversionWorker.request`
writes neither the `Data` entry nor the `JobTags.sizeBytes` tag for a size nobody knows, since a
tag reading `size-bytes:0` would come back through `Reattachment` as a confident claim that the
user's file is empty -- and `reattach()`'s `?: 0L` is gone for the same reason.
A join's total is `InputQuery.total`, which is null the moment a *single* input cannot be sized.
Summing the ones that answered was the competing reading and is rejected: a lower bound is
indistinguishable from a real total once it reaches the space check, so the guard would reserve
for half the job and pass. Reverting it to `sumOf { it ?: 0L }` records `[1111]` for a two-file
join whose second input nothing can measure.
Work already in the queue keeps the old conflation, and there is no fixing it. The previous
`request()` always wrote `putLong(KEY_SIZE_BYTES, sizeBytes)`, so a job enqueued before this
commit for a file nothing could size carries the key *present* and set to zero -- which reads
back as a declared size of zero and is trusted, exactly as before. Its `lmc.size-bytes:0` tag
reads back the same way, so `reattach()` shows such a card "0 B" rather than "Size unknown".
Nothing can separate that from a genuinely empty file after the fact, and a rule that treated a
declared zero as suspect would only rebuild the conflation facing the other way. WorkManager
keeps finished work for about a week, so this is a bounded window that clears itself; new work
never enters it.
`hasSpaceFor`'s KDoc claimed peak usage was "roughly input + output at once" while the arithmetic
reserved `input + 128 MB`. The arithmetic is what stays and the doc now says why: `bytes` is the
input's size standing in for the output's, generous for the ordinary conversion (which is asked
for precisely because it shrinks its input) and short for a re-encode to a bulkier codec; the
128 MB absorbs that error and the transient double copy while `publish` runs. Reserving
`input + output` outright would refuse jobs that fit. This is a pre-flight check that stops an
obviously impossible job from spending minutes finding out, not a guarantee -- a conversion that
runs out of space anyway still fails through its engine.
The measurement side of that line is untouched on purpose. `StorageManager.getAllocatableBytes`
is a separate entry with its own device evidence and its own `informational += "UsableSpace"` in
the lint block; this commit is about the number going *in*. `hasSpaceFor(bytes: Long)` keeps its
signature and stays open, so nothing overriding it had to change.
The file card says "Size unknown" rather than `0 B`. Handled at the call site rather than inside
`formatBytes`, because a formatter that invented a number would be the defect on screen; the card
already degrades in words for a file nothing could read.
Five of the seven new tests were red before a line of production code moved, with the numbers
they were about: `expected:<4321> but was:<0>` for a picked file, `expected null, but was:<0>` for
one nothing can measure, `expected:<[1111, 2222]> but was:<[0, 0]>` for the join picker, and
`expected:<[4321]> but was:<[0]>` and `expected:<[3333]> but was:<[0]>` for what the two workers
asked the space check. The tests assert on the *question* rather than the verdict, which matters:
one that only checked whether the job ran would have passed against the defect, since the defect
is that the guard is vacuous rather than that it refuses.
The remaining two needed the new call to exist first, so each was proved by mutation instead.
Answering the unknown with `hasSpaceFor(0L)` inline leaves `expected:<[]> but was:<[0]>` in both
workers; refusing it instead leaves `an unknown size must not end the job; got Failure {error :
Not enough free space to convert.}`. Making the worker always measure rather than trust a declared
size leaves `expected:<[9999]> but was:<[4321]>`.
`join()`'s own use of `InputQuery.total` is tested separately from the function, because
`StagingCleanupSupport` already records what that distinction costs: a tool can be provably right
while nothing calls it. `SucceedingWorkerFactory` now keeps the input `Data` of every request that
reaches a worker -- the only place it is legible, since `WorkInfo` hands back a job's tags and its
output and never the `Data` it was built with -- and the test reads the enqueued total off it.
Restoring `inputs.sumOf { it.sizeBytes ?: 0L }` leaves every other test in the change green and
this one red with `a total that could not be worked out must not be enqueued as a number`.
`ConversionViewModelProbeFailureTest` expected `InputFile(INPUT, "input", 0L)` for an authority no
provider serves. It expects `sizeBytes = null` now, which is the behaviour change stated where a
reader will meet it.

Name a finished file after the job that made it
Six places decided what a converted or joined file should be called, and not one of them asked
the job. `JoinViewModel` reported `JoinState.Saved("joined.mp4")` whatever the format;
`JoinScreen` opened `CreateDocument("video/mp4")` and launched it with `"joined.mp4"`. On the
convert side `save()` and `suggestedOutputName()` built the name from `_settings.value.spec`, and
the screen took the MIME type from the same place -- the picker as it stands *now*, which is not
the spec the job ran with.
All six are right today, and all six are right by accident. The join screen has no format picker,
so the three MP4 literals agree with `ConcatWorker.request`'s default. The conversion pickers are
drawn only in the `Ready` state, so the settings cannot move between enqueue and save. Neither
accident is load-bearing anywhere it is written down.
One of them has already stopped holding, quietly. A job picked up by `reattach()` ran with a spec
that was never in this ViewModel's settings, because those settings belong to a process that no
longer exists -- so a reattached MP3 conversion is offered `.mp4` and `video/mp4` today. The
previous commit made that path more reachable rather than less: `Reattachment` exists precisely
to find work this ViewModel did not start.
The fix is to ask the only thing that knows. The spec travels to the worker as input `Data` and
`WorkInfo` hands input `Data` back to nobody, so the worker is the single point at which the
input's name and the spec that ran are both in scope. Both workers now report the two derived
strings -- the name to suggest and the type to open the dialog with -- in their output `Data`,
and they ride on `ConversionState.Converted` and `JoinState.Joined` from there. `save()` reports
what it saved rather than recomputing it, and both screens read the name and the MIME type off
the state they already collect, remembering their `CreateDocument` contract against that type
instead of a literal. The MIME type is not cosmetic: some providers rewrite a document's
extension to match it, so an MP3 offered as `video/webm` can arrive with the wrong one.
`suggestedOutputName()` is deleted rather than repaired. With the answer on the state there is no
caller left for it, and an accessor recomputing the same string would only be a second place for
it to be wrong -- which is what it was.
`ConcatWorker` gains `DEFAULT_FORMAT` and `outputNameFor(format)`. Three copies of "MP4" is the
shape this entry is about, and the input-Data default, `request`'s parameter default and the
ViewModel's fallback for a job that predates this change are exactly three copies.
Work already in the queue carries neither string, and WorkManager keeps finished work for about a
week, so that is the ordinary case for a few days rather than a corner. Those fall back to the
old derivation, which is a guess -- but it is the same guess the app was already making, it is
confined to jobs enqueued before this commit, and for such a job there is genuinely nothing
better to hand. New work never reaches it. The join's fallback is not even a guess: the format
`ConcatWorker.request` has always defaulted to is the format such a job really used.
`reattach()`'s KDoc carried this as a known wart it was deliberately leaving alone. That
paragraph is now a description of the fix rather than of a defect.
Tested at both ends, since either alone would pass while the other was wrong.
`WorkerOutputNamingTest` runs the real worker on an MP3 job -- nothing like the default preset, so
a name built from the picker is visibly wrong rather than accidentally right -- and compares the
whole success `Result`, which is what makes a missing key fail rather than go unnoticed. The two
ViewModel tests drive a finished job and then move the picker, which is what a reattached job
amounts to from the ViewModel's point of view.
Restoring just the two name sources -- `save()`'s `outputNameFor(displayName, _settings.value.spec)`
and `JoinState.Saved("joined.mp4")` -- turns them red with
`expected:<holiday_converted.mp3> but was:<input_converted.webm>` and
`expected:<joined.mkv> but was:<joined.mp4>`. The convert side loses the extension *and* the name:
`_settings.value` had been moved to WebM, and the display name a reattached job cannot supply had
already fallen back to the placeholder.

Give every job a staging path of its own
`<cacheDir>/conversions/` is shared by the convert tab, the join tab and `ConcatEngine`, and
until now none of the three named a file that belonged to one job. A conversion derived its name
from the input's display name, so two `holiday.mp4` from different folders wrote the same file.
A join used the constant `joined.<ext>`, so any two joins of one format did. The list file was
the constant `concat_list.txt`, so any two joins at all did, and one of them would read the
other's input list.
The naming half is not a hypothesis. Two independent conversions on a Pixel each computed
`cache/conversions/input_converted.mp4`, the second silently overwrote the first, and a tag query
in a fresh process then returned **two SUCCEEDED `WorkInfo`s naming that one file** with one file
on disk. That is the collision reaching the point where it makes a *fix* ambiguous rather than
just a file: `Reattachment` can offer the bytes, because they are the user's either way, but it
cannot say which job produced them.
`StagingNames` keys the name on the WorkManager request id. That id is what stays still across a
retry -- `WorkerWrapper` builds `WorkerParameters` from the `WorkSpec` id and only increments
`runAttemptCount` -- which matters more here than uniqueness does, and matters more since the
previous commit made retries routine. A failed attempt deletes its staged file on the way out,
and that only collects the partial the *previous* attempt left when the name has not moved.
Opaque rather than sanitised, deliberately. The staged name is never shown to anyone: `save()`
recomputes a suggested name and the user picks the real one in the SAF dialog. So there was
nothing to lose by dropping the display name, and something to gain -- a provider-supplied
display name can contain a separator, be empty, or be four kilobytes long, and `File(stagingDir,
"../escape_converted.mp4")` resolves to a path outside staging. That was reachable before this
commit and is now unreachable by construction rather than by a sanitiser that has to be right
about every case. There is a test for exactly that name.
The extension stays, and is not decoration: `FFmpegConcatCommand` names no output muxer, so
FFmpeg infers it from the output path. A fully opaque name would quietly produce the wrong
container.
`ConcatEngine`'s list file is derived from the output it belongs to rather than taking another
parameter, so the two cannot drift apart, a directory listing shows which list belongs to which
join, and the sweep ages them together.
Three neighbouring comments claimed things that are no longer true, and are corrected rather than
left to mislead the next reader:
- `Reattachment.Ambiguous` said it "resolves on its own once each job stages under a name of
its own". It now does -- for work enqueued from here on. The case is **kept**, because the
queue outlives the change: WorkManager holds finished work for about a week, and the jobs
likeliest to be sitting in it when this code first runs are the ones named the old way.
Behaviour is unchanged and `ReattachmentTest` is untouched.
- `OutputPublisher.sweepStaging` justified its age rule partly on there being "no per-job
namespacing". There is now, and the rule still stands on its own: per-job names stop two jobs
from sharing a file, and say nothing about whether a file's job is still running, which is the
question a sweep actually asks. Same for `StagingSweep` and the note in
`LibreMediaConverterApp`.
- Both ViewModels' `reattach()` explained aliasing as something nothing prevented. Narrowed to
what is still true of work already in the queue.
`ConcatEngineTest` asks `StagingNames` for the list file's name instead of spelling out
`concat_list.txt`. That is the difference between a test and a tautology: a literal there would
have gone on passing after the rename while asserting that a file nothing creates does not exist.
The same trap was live in the two worker tests from the previous commits, whose staged-file
assertions computed a path of their own -- they now assert on the staging directory being empty,
which cannot go vacuous when a name moves.
`PerJobStagingTest` drives the real worker, because the naming function was never the part that
was wrong: what was wrong was which name the worker asked for. Two jobs converting one file must
leave two files; a second attempt at one job must not leave a second; and a display name that
climbs out of staging must not. The first and third fail before the change with "each job must
have staged its own file, found [input_converted.mp4] expected:<2> but was:<1>" and "the output
belongs in staging expected:<1> but was:<0>" -- the latter because the file had landed in
`cacheDir` instead.

Let a cancelled conversion stay cancelled
Both workers' outer `catch (e: Throwable)` caught `CancellationException` along with everything else and answered it with a `Result`. `runMedia3OrFallBack` goes out of its way to rethrow cancellation rather than fall back to software, and then the catch above it converted it anyway. A coroutine that reports completion inside a scope which has already been cancelled is structured concurrency's one rule broken, and it is the kind of break that stays quiet: nothing downstream complains, and the next thing to hold a resource across that boundary is the thing that finds out. Nothing on screen disagreed today, which is why this is a low-severity entry rather than a bug report. WorkManager cancels the worker's coroutine through `WorkerWrapper.interrupt`, which cancels `workerJob` with a `WorkerStoppedException`; the surrounding `withContext(workerJob)` then throws that whatever the worker returned, and `launch()` resolves it as `ResetWorkerStatus`. The returned `Result` is read only when nothing stopped the worker at all. So the change is about the shape of the code rather than about a symptom. One behaviour does move, and it is worth naming rather than discovering later. A cancellation that is *not* WorkManager stopping us -- FFmpegKit reporting `ReturnCode.isCancel`, which cancels the continuation -- now leaves `doWork` as a cancellation, and `WorkerWrapper` resolves a self-cancelled worker as `Resolution.Failed()` with no output data instead of the `Result.failure(KEY_ERROR ...)` it used to build. Both ViewModels already fall back on blank output data, deliberately and with a test, so the user sees "Conversion failed." either way. That is also the honest answer: the only route to `isCancel` is a cancellation someone asked for. The `staged.delete()` on that path is kept, and moved into the new branch rather than left to the one below it. A cancelled attempt leaves a partial in staging, the next attempt starts `doWork()` from the top rather than resuming it, and this catch holds the only handle to the file. Reaching any of this from a JVM test needed one more thing: `doWork` called `MediaProbe.probe` directly, and it was the last caller bypassing `ConversionDependencies.probe`. FFprobe's loader throws a bare `java.lang.Error` with no native library present, so no unit test could reach a single line below it. The seam's own KDoc says this is what it is for -- coverage of the branches that only run when something goes wrong -- and the default is the same real probe, so the app and the instrumented tests are unchanged. `WorkerCancellationTest` drives the real worker through a real `WorkManager` to the software engine, forced with `FORCE_SOFTWARE` because it is the one preference that decides without consulting the input, so the test does not depend on a routing rule it is not about. The engine stub writes bytes before it throws, which is what makes the delete assertion mean something: a stub that only threw would let a missing `delete()` pass. Three cases -- cancellation propagates, cancellation still deletes, and an ordinary failure is still answered with a `Result` carrying its message, which is the half that would break if the rethrow were widened past cancellation. Before the fix the first of those failed with "cancellation must leave doWork as cancellation, not as a Result; got null" -- `runCatching` had nothing to report, because `doWork` had returned.

Retry work the system refused to start, instead of failing it terminally
`ConversionWorker`'s KDoc says the queue survives process death, and that is the app's stated
reason for choosing WorkManager at all. A Pixel 10 Pro XL says otherwise. An 18-minute
transcode was killed mid-write with `kill -9`; 119 seconds later, on a natural dispatch with
no `cmd jobscheduler run` anywhere in the session, WorkManager recovered it by itself and the
system refused it:
WM-ForceStopRunnable: Found unfinished work, scheduling it.
ActivityManager: Background started FGS: Disallowed [callingPackage:
org.libremediaconverter; uidState: CEM; BFGS denied: true; code:DENIED]
WM-WorkerWrapper: android.app.ForegroundServiceStartNotAllowedException
WM-WorkerWrapper: Worker result FAILURE
WM-Processor: Processor 3d1c9862 executed; reschedule = false
`Found unfinished work` is the clean process-death recovery path, not a force-stop. The job was
ordinary -- `Priority: 300 [DEFAULT]`, not expedited -- so there was no allowance it could have
carried. `HAS_FOREGROUND_EXEMPTION` was set on it and it was still denied; that flag governs the
runtime guarantee once a service is running, not permission to start one.
The cause is structural rather than subtle. `setForeground(...)` sat above `return try {`, so its
throw escaped `doWork()` without reaching `handleTimeoutIfNeeded`, `Result.retry()`, the
`workDataOf(KEY_ERROR ...)` or `staged.delete()`. Three separate costs, all measured on the
device: `reschedule = false`, so nothing ran again despite `run_attempt_count=2`; output `Data`
of `X'ABEF000100000000'`, a header with zero entries, so the screen said "Conversion failed."
with nothing to add; and 2 MB of a partial `long_input2_converted.mp4` left in staging.
`ConcatWorker` had the same shape.
So `setForeground` moves inside the `try` in both workers, and the staging handle is named just
above it -- `createStagingFile` only builds a path, nothing is written until an engine opens it,
so naming it early costs nothing and makes the catch total. `MediaProbe.probe` was outside the
`try` for the same reason and had the same problem; it is now inside too. On a retry the staged
name is unchanged, so the delete on the way out collects the partial the killed attempt left
behind rather than orphaning it.
What to return was the real decision. `Result.retry()`, because the denial is about *when* the
job ran and not about the job: the file is fine, the settings are fine, and the one thing that
grants an app permission to start a foreground service is being in the foreground, which the
user supplies by opening the app. But WorkManager never gives up on its own, so an unbounded
retry means a job nobody comes back for waking the device forever while the screen says "paused"
and never explains itself. `FailureOutcome` therefore bounds it at ten attempts, chosen against
the default backoff rather than as a round number: exponential from
`WorkRequest.DEFAULT_BACKOFF_DELAY_MILLIS` (30 s), doubling, clamped at `MAX_BACKOFF_MILLIS`
(5 h), which spans about 8 h 30 m before the eleventh attempt fails with a message the user can
act on. The counter is `runAttemptCount`, which counts every attempt and not only denied ones --
WorkManager exposes no other -- so a transcode already retried ten times by the six-hour budget
will fail on its first denial rather than getting ten of its own. That is accepted rather than
overlooked, and the timeout branch ignores the count entirely so the budget's own retries are
untouched.
The rule goes in `FailureOutcome` rather than beside it, which is what its KDoc asks for: isolate
a decision whose triggering condition cannot be provoked in a test. It now reads the stop reason
*and* the cause, with precedence stated rather than left to branch order -- once something has
stopped the worker, the exception it was holding describes that stop and not a reason of its own.
The match is on `ForegroundServiceStartNotAllowedException` exactly, never on its
`IllegalStateException` supertype: a muxer that was never started throws one of those too, and
matching the supertype would retry every ordinary failure for eight hours.
Expedited work is still not used, and this is not an argument for it. It maps to JobScheduler
expedited jobs with a short quota, which is the wrong shape for a multi-minute transcode; the
exemption it buys is for starting, and the quota it costs would be paid by every job.
Tested at both levels, because only one of them bites. `FailureOutcomeTest` gains six cases for
the rule -- retry at the bound, give up past it, an unrelated `IllegalStateException` that must
not be mistaken for a denial, a stop reason winning over the exception, and the budget timeout
ignoring the count. `DeniedForegroundStartTest` covers the wiring, which is where the defect
actually was: a `ForegroundUpdater` whose future completes exceptionally makes `setForeground`
throw exactly what the platform throws, because `WorkForegroundUpdater`'s own comment says it
propagates the exception to the caller and `ListenableFuture.await()` unwraps the
`ExecutionException` on the way. Moving `setForeground` back above the `try` turns all four of
those red with a bare `android.app.ForegroundServiceStartNotAllowedException`, which is the same
line the device logged.
Four comments claimed the old behaviour and are corrected with it. `ConversionState.Waiting`
said the budget had run out; `observe()`'s ENQUEUED branch said the budget was the likely cause,
where a denied restart is now the likelier of the two; and `Reattachment.choose` justified
excluding FAILED partly on interrupted workers coming back FAILED "rather than retried", which is
the sentence this commit falsifies. The exclusion stands on its own and says so now.
The bound's own KDoc says what giving up does *not* buy, too. `FOREGROUND_DENIED` reports through
a FAILED job and `Reattachment` excludes FAILED, so a user who was not watching at the eleventh
attempt meets an empty screen rather than the message. What the bound reliably buys is the end of
the retrying.
Both `Waiting` screens change their wording. The state is `ENQUEUED` with a run attempt behind
it, which cannot distinguish the two causes that now reach it, and the old copy named only the
six-hour budget -- which is now the less likely of the two. "Keeping the app open helps it along"
covers both, and for a denied start it is not filler but the actual remedy.

Guard the native boundary against what it actually throws
D14: picking a file died instead of reporting an unreadable one when FFmpegKit's native library could not load. `probeWithFFprobe` guarded its call with `catch (e: Exception)`, and `ConversionViewModel.onInputPicked` guarded nothing, so the failure escaped a `viewModelScope.launch` -- which has no handler, and on a device ends the process. All three of the obvious narrow guards catch nothing, which is why this needed reading the AAR rather than guessing. `NativeLoader.loadLibrary` catches the `UnsatisfiedLinkError` that `System.loadLibrary` raises and rethrows a *bare* `java.lang.Error` wrapping it, so `UnsatisfiedLinkError` never escapes and the escaping type carries no information at all. Every touch of the class after the first is a different type again -- `NoClassDefFoundError` -- so a guard written for the first shape lets the second pick onwards crash, which is the harder half to notice. Both are in the test output verbatim. `catch (Throwable)` was the wrong answer for the reason the audit gave: it would swallow a genuine `OutOfMemoryError` in a method that spawns a native process, turning "this device is out of memory" into "this file looks unreadable" and letting the app act on it. So the line is drawn by a named predicate, `isNativeLoadFailure`, rather than by the catch clause -- every class-loading shape is a `LinkageError`, and nothing that means the JVM is failing is one. That disjointness is what makes the guard narrow. This is consistent with the position `config/detekt/detekt.yml` already takes for `TooGenericExceptionCaught`: the boundary's failure types are undocumented, so guessing crashes the app on a file it could have reported. One level up the opposite mistake is available too, and the predicate is what lets both be avoided at once. `TooGenericExceptionThrown` is relaxed for the test source sets only. A test that reproduces a failed native load has to throw what the library throws, and a tidier subclass would leave it passing against a defect it no longer reproduces. Main source is untouched by that and throws nothing generic. `ConversionDependencies.probe`'s KDoc is rewritten rather than left. It said this hazard was "deliberately not fixed here ... its own commit, with its own test", which this is -- leaving it would have replaced one true comment with a false one, which is the same defect class as the D11 work. Both halves are covered independently: reverting the `MediaProbe` catch reds only the two `MediaProbeNativeLoadTest` cases, reverting the ViewModel guard reds only the two injected-seam cases, and widening the ViewModel guard to `Throwable` reds the OutOfMemoryError case -- so the narrowness is pinned, not just the catch. Audited the sibling boundaries named in the audit and left all three alone: `FFmpegEngine` and `ConcatEngine` both construct and run under `catch (e: Throwable)` in their workers, and `Media3Engine` has no native loader of this kind and already routes failures through `runCatching`.

Delete the half-written destination instead of leaving it under the user's name
publish() streamed the staged file into the SAF destination with copyTo and had no
answer for a copy that failed partway. The destination volume filling up is the obvious
way in; a provider giving out mid-write is the other. Either way the bytes it had
managed stayed at the name the user picked, while the UI said "Could not save the file".
The user was left holding a truncated file they had just been told was never written,
and nothing in the app would ever tidy it up -- staging cleanup reaches
<cacheDir>/conversions and nowhere else, by design.
So a failed copy now deletes the document. The interesting part is not the delete, it is
what stops it, because removing a file the user already had would be a far worse defect
than the one being fixed.
Only a document URI. DocumentsContract.deleteDocument is the only delete this code has
any right to attempt and it is defined on document URIs, so isDocumentUri() gates it.
That is not a formality: it asks the package manager whether anything answers
ACTION_DOCUMENTS_PROVIDER for the authority, so a file:// path, a MediaStore item or a
content URI from an ordinary provider all fall out here untouched.
Only a destination that was empty when we started. The size is read BEFORE the stream
is opened -- opening for write truncates, so afterwards the question can no longer be
asked -- and the delete runs only when the answer was positively zero. Every
destination that reaches publish() today comes from the SAF CreateDocument contract, so
in practice it is a document this app created seconds earlier; but publish() cannot
verify that from a Uri, and a provider that hands back an EXISTING document for a name
the user re-picked would otherwise have its file deleted rather than merely truncated.
Truncated is bad. Gone is worse, and it is the user's file either way.
That guard fails towards doing nothing. A provider that does not report _size, a query
that returns no row, a resolver call that throws -- all of them land in "not known to
be empty", so the fix is conservative rather than universal: it will not clean up
behind such a provider, and it will not delete anything of theirs either. The defect is
closed for providers that answer a size query; ExternalStorageProvider backs its
documents with real files, so a freshly created one reports 0, but that is reasoning
about it rather than a run against it. Stated here rather than implied, because
"fixed" would overclaim what was verified.
The original failure is what the caller sees. Cleanup runs in its own runCatching and a
throw from it is attached to the original exception as a suppressed one. deleteDocument
reports failure two different ways -- false, or a rethrown RuntimeException -- and
neither is worth failing the save over, because the save has already failed.
ConversionViewModel.save() reports e.message, and "could not delete the half-written
file" is not what to tell someone whose disk just filled up.
Two smaller decisions in the control flow. The whole `use` is guarded, not just copyTo:
a close() that throws while flushing IS the disk-full case and it arrives after copyTo
has returned successfully, so guarding only the copy would miss exactly the failure this
commit is about. The cost is that a file whose every byte reached the provider before a
failing flush is deleted too, which is the right way round -- a flush that failed means
the bytes are not durably there. And openOutputStream's own failure is deliberately
OUTSIDE the guard: nothing has been written at that point, so there is nothing of ours to
remove.
Nothing else in the class moves. hasSpaceFor, discardStaged and sweepStaging are
untouched, and so is save(): the staged file is still deliberately kept on a failed save,
for the reason its own comment gives -- it may be the only copy of an hour of
transcoding, and now the destination genuinely does not have it either.
Seven tests, JVM, Robolectric. The failure has to be injected, which is what shapes them:
Robolectric's ShadowContentResolver consults its registered-stream map before it reaches
any provider, so a test can hand out a stream that writes 512 bytes to a real file and
then throws "No space left on device" while a fake provider answers the size query and
the delete against that same file. The provider is registered twice under two authorities
and two component names, once with the ACTION_DOCUMENTS_PROVIDER intent filter and once
without, which is the only way to have a content URI that is not a document URI. The
delete is observed by the wire names DocumentsContract.deleteDocument actually sends --
"android:deleteDocument" and the "uri" extra -- because both constants are hidden from
the public SDK.
fails partway leaves nothing RED before the fix: expected the delete, got []
close that fails while flushing RED before: the file was still there
cleanup that fails RED before: suppressed was []
already held bytes is not deleted green before the fix -- see below
not a document is left alone green before the fix -- see below
cannot be opened at all green before, and must stay so
succeeds, every byte, no delete green before, and must stay so
The last four are green against the unfixed code for a reason worth writing down: the old
publish() never deleted anything, so every guard passes trivially. They pin the guards
rather than the defect, and pinning is only worth something if the pin is real, so both
were reverted on their own:
- dropping `if (destinationWasEmpty)` fails "a destination that already held bytes is
not deleted" with "a document this app did not create must survive"
- dropping the isDocumentUri() check fails "a destination that is not a document is
left alone" with "deleteDocument has no business on a URI that is not a document
expected:<[]> but was:<[content://...test.plain/document/holiday_plain.mp4]>"
Both were restored. 193 unit tests green.
UnopenableUriTest's unwritable-destination case (an authority with no provider behind it)
is unchanged and keeps passing by two independent routes: the size query on a dead
authority yields "not known to be empty", and the failure itself comes out of
openOutputStream, which sits outside the guard. It is an instrumented test and was
compile-verified here, not executed -- instrumented tests do not run on this host
(CLAUDE.md). Its JVM twin is in the list above.

Keep the selected tab through the recreation targetSdk 37 guarantees
AppRoot held the selected tab in `remember`, which survives recomposition and nothing
else. MainActivity declares no configChanges, so every rotation and every resize
destroys and recreates the Activity, and the tab went back to Convert each time.
The KDoc directly above that line is the argument for why it matters: from targetSdk 37
Android ignores screenOrientation, resizableActivity and the aspect-ratio limits on any
display at least 600dp wide, and the Android 16 opt-out is gone, so the app is resized
and rotated whether or not it is ready. The shell was written for that case and then
lost its own state to it. Both ViewModels are Activity-scoped and come back intact, so
a conversion in flight was never at risk -- only the tab, which is what makes this
visibly wrong rather than merely stale.
rememberSaveable, with a Saver that writes the constant's NAME. Three ways to make an
enum saveable and the reasons for this one:
- autoSaver already accepts it. An enum is Serializable, so plain
`rememberSaveable { mutableStateOf(Destination.CONVERT) }` compiles, works, and
passes the restoration test below unchanged. That is a reason to be explicit, not a
reason not to be: nothing in the declaration says Destination has to stay
Serializable, so the implicit route keeps working right up until someone makes it a
value class or a sealed interface -- and then stops, silently, on a path only a
rotation reaches.
- The ordinal is a position, not an identity. Inserting a tab between Convert and Join
would redefine every value already written down. A name only changes when someone
renames a constant, which is an edit that shows up in a diff. It also reads as
itself in a Bundle dump.
- An unknown name restores to null, which rememberSaveable treats as "nothing saved"
and falls back to Convert. That is exactly what a downgrade or a renamed constant
leaves behind, and Convert is the right answer for it.
The test runs on the JVM, which took two changes to reach.
AppRoot and Destination are `internal` rather than `private` -- the unit test source set
is a friend of main, so this stays invisible outside the module -- and AppRoot takes its
`content` as a defaulted parameter instead of calling Content() directly. Nothing in the
app passes it. It is there because both screens resolve a ViewModel, which builds a
WorkManager and a media probe, and none of that has anything to do with which tab is
selected; the test hands in a tagged Box and drives the shell alone. Content() stays
private and is still what the app gets.
compose-ui-test-junit4 joins the JVM test source set. It was already in the catalog for
androidTest, it is inside the prerelease guard via its androidx. group, and its version
comes from the BOM, so this adds no new pinning argument. It is there because
createComposeRule() runs under Robolectric: a red test in androidTest is one nobody on
this host can execute (CLAUDE.md), which is not a loop anyone can work in.
ui-test-manifest is NOT repeated on that source set. It supplies the ComponentActivity
the rule launches, and the existing debugImplementation entry already puts it in the
merged manifest the unit tests build against -- checked by removing the line and
watching AppRootRestorationTest stay green, rather than assumed.
What the test does and does not prove. StateRestorationTester's
emulateSavedInstanceStateRestore() disposes the composition and rebuilds it, so anything
held only by `remember` is gone -- that is what makes it bite. It saves into an in-memory
map rather than parcelling through a Bundle, so it cannot tell a name from an ordinal
from autoSaver. The saved representation is pinned separately by three pure-JVM tests
over the Saver itself, which is where the choice above is actually held down.
Verified by writing it red first, against the restructured AppRoot with `remember` still
in place: all three restoration tests failed at the post-restore assertion with
"Expected exactly '1' node but could not find any node that satisfies:
(TestTag = 'content:JOIN')", while every assertion before the restore -- including the
bar's own selected state -- passed. Six new tests, 186 green in all.
Not addressed here, and deliberately: MainActivity still declares no configChanges, and
should not. Handling the configuration change is not the same as keeping one enum, and
Compose's saved-state machinery is the mechanism the platform intends for it.

Merge the staging-cleanup fix, and pin the seam the two changes share
The two changes meet at one line. `pendingStaged` is recorded in the `SUCCEEDED` branch of each ViewModel's `observe()` collector, and reattachment reaches `Converted`/`Joined` through that same collector rather than by building the state itself -- so a job picked up from a previous process arrives with its cleanup handle already set, and "Start over" on it deletes the staged file exactly as it does for a conversion run in this process. Nothing had to be added for that; it falls out of routing reattachment through `observe()`. Which is precisely why it needed a test. The claim is structural -- one assignment, in one function, that both changes assume -- and the conflict here was `JoinViewModel`, where the cleanup change edits a collector body that the reattachment change had moved out of `join()` into a private `observe()`. Resolving that by putting the assignment back in `join()` would compile, pass every test either branch brought, and silently leak a full-size file on the one path both changes were written for. `ReattachedCleanupTest` fails if it lands anywhere else. Verified the way the cleanup commit verified its own wiring: deleting `pendingStaged = staged` from `ConversionViewModel.observe()` fails "start over on a reattached conversion deletes the staged file" alongside the two `ConversionViewModelCleanupTest` cases that share the line. Restored, all 183 JVM tests pass. The reattachment path also gains JVM coverage it could not have had before this merge, since Robolectric and the `ConversionDependencies` seams arrived with it: a ViewModel constructed after a job has already finished, with nothing left that observed it, now demonstrably reaches `Converted` with the display name recovered from the job's tags -- on a machine where no instrumented test can run. Conflict resolution: both sides kept in `JoinViewModel`, with the cleanup handle declared alongside the other fields and the reattachment `init` after them. Nothing else conflicted; `ConversionViewModel` merged clean because the reattachment change touches the `CANCELLED` and `FAILED` branches while the cleanup change touches `SUCCEEDED`. No build file, manifest or `OutputPublisher` line in this merge is mine -- they arrive from the cleanup commit verbatim. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Reattach to conversions and joins the ViewModel did not start
The queue surviving process death is the stated reason this app uses WorkManager, and
the ViewModel was where that protection stopped. `activeWorkId` and `observer` are
plain fields, so a process reclaimed after a conversion finished came back to Idle
while the output sat in `cacheDir` with nothing in the UI able to reach it. The
realistic window is not a crash mid-transcode -- it is the job finishing, the user not
saving yet, and the process being reclaimed hours later as an ordinary background one.
Both ViewModels now query their own worker's class name on init and pick up what they
find. Nothing is persisted for it, and nothing needed to be: `WorkRequest.Builder`
seeds every request's tag set with `workerClass.name` (`tags = mutableSetOf(
workerClass.name)`, work-runtime 2.11.2), and R8 keeps those names through
work-runtime's own consumer rule, `-keepnames class * extends
androidx.work.ListenableWorker`. A UUID in a `SavedStateHandle` would have been both
more machinery and less: it cannot find work enqueued by a previous install.
What the query cannot return is the job's input. `WorkInfo` hands back id, state, tags,
progress, output and run-attempt count -- never the `Data` a request was enqueued with
-- so a ViewModel could see that a conversion existed and where its output went, but
not which file it was converting. The display name and size therefore ride on tags too,
which is the whole of the production change to the request builders. The picked `Uri`
deliberately does not: nothing in a reattached state reads it, and a `content://` grant
taken by a picker in a process that no longer exists is not something to hand back as
though it still worked.
The decision is a pure function on the JVM test stack, following `FailureOutcome`:
`Reattachment.choose` takes what WorkManager reported and answers which job, if any.
Cancelled work is excluded -- the user already said no. Failed work is excluded, which
matters more than it looks now that a device has shown an interrupted worker coming
back FAILED rather than retried, its restart's `setForeground` refused as a background
foreground-service start: nothing marks a failure as seen, so it would otherwise
reappear on every launch. A success whose staged file is gone is excluded, because a
Save button that fails on tap is worse than no button. Live work outranks a finished
result, since a running job holds a foreground notification and someone opening the app
while that notification is in the shade is looking for that conversion.
Where several jobs qualify, the newest staged file wins, and that is not a detail.
Losing a tie is not the same as waiting for the next launch: the tag query has no
`ORDER BY`, so its order is unspecified but stable, and an arbitrary winner would keep
winning every launch while the other result stayed unreachable for as long as its file
existed. It is reachable today -- dismiss one result with "Start over", which leaves its
file behind, then convert something else and do not save it. `WorkInfo` carries no
timestamp of any kind, but the edge is already stat'ing the file, so the file's own
mtime is the ordering. A clock that moves backwards makes it a heuristic; an order that
is unspecified and repeats itself is worse.
Aliases are the tie that does not resolve, and that case is not hypothetical. A tag
query on a device returned two SUCCEEDED jobs whose output paths were both
`.../conversions/input_converted.mp4`, with one file on disk -- the staging name is
derived from the input's display name, so a later job overwrites an earlier one's output
and both go on reporting it. Checking the file does not separate them, and neither does
its mtime, since they share it. So the two halves are separated instead. The file is
offered, because it is the user's file either way and losing it is the defect being
fixed; the label is not, because saying which job produced it would be a guess.
`Reattachment.Ambiguous` says so and the card falls back to a neutral name rather than
borrowing the other job's. Aliases whose tags are identical -- the ordinary case, the
same file converted twice -- stay attributed, since nothing turns on which wrote it.
Age is not filtered on, and cannot be: WorkManager keeps finished work about a week and
prunes on its own schedule, so a query in a fresh process routinely returns jobs from
earlier sessions. Whether the staged file is still there is the only signal separating a
result still worth offering from one already dealt with, which is why that check carries
the weight.
Two smaller behaviours fall out of reattaching rather than starting:
- A reattached job that is cancelled lands on Idle rather than Ready. Ready would put
a Convert button over an input URI that belongs to a dead process. `observe()` takes
the cancelled destination as a defaulted parameter, so a job started here is
unchanged.
- A FAILED job's message falls back when blank, not only when absent. A worker killed
before it can report leaves no output data at all, and an exception's message can be
the empty string; both used to reach the screen as a failure with nothing said.
Deliberately not fixed here, each being its own change: the save dialog's suggested name
and MIME still come from the current picker rather than from the job that ran, so a
reattached job in a non-default format is offered the default extension; a result
dismissed with "Start over" still keeps its staged file, so it can be offered again next
launch -- the file check closes that for free once the file is deleted; and
`setForeground` still sits outside `doWork`'s try, so its throw bypasses the retry
decision entirely.
Tested where it can be. 28 JVM tests cover the choice and the tag round trip, including
the ordering, the aliasing rules and a display name that looks like another tag. The
reattachment itself is instrumented: a ViewModel constructed against the real
WorkManager is the next launch, with no memory of the work. `WorkManagerTestInitHelper`
is deliberately not used -- its `setDelegate` replaces the singleton for the whole
process, which would quietly turn `ConversionWorkerTest` into a synchronous test double
depending on class order.

Delete staged output the user never saved, instead of waiting for the OS
Every conversion writes a full-size file into <cacheDir>/conversions/. save()
published it and deleted it, but reset() -- what the "Start over" button on the
Converted and Joined states calls -- dropped the File reference and left the file
behind. Converting something and deciding not to save it is an ordinary path
through the UI, so it leaked a full-size copy every time. cacheDir is evictable,
so this was never unbounded growth; it was the app relying on the OS to clean up
after it, and on a device under no storage pressure "eventually" means never.
OutputPublisher.clearStaging() was written for exactly this and called from
nowhere. It is NOT wired up here -- it is deleted. It emptied the directory
unconditionally, and the convert tab, the join tab and ConcatEngine's
concat_list.txt all share that directory with no per-job namespacing (D8), so a
blanket delete could take a file out from under a running job. Two narrower
methods replace it:
discardStaged(file) one file, guarded. The handle reaches the ViewModel as a
path string in WorkInfo.outputData and becomes a File with
nothing checking where it points, so this compares the
CANONICAL parent against the staging dir -- the naive
string comparison accepts conversions/../elsewhere.
sweepStaging(now) age-based, for orphans no ViewModel is left to clean up.
The cleanup handle is a ViewModel field, not something read back out of the state
machine, because the state machine cannot answer it on the path that needs it
most: a failed save lands on Failed(message), which carries no file reference at
all. On that path the file is deliberately kept -- it may be the only copy of an
hour of transcoding and the destination did not receive it, so deleting to tidy a
cache directory would destroy the work. It stays collectable by a later reset()
or by the sweep.
The sweep runs once per process from a new Application subclass, off the main
thread. The reason it cannot race a live job is the grace period, not ordering:
WorkManager initialises through androidx.startup's InitializationProvider, a
ContentProvider, so it is already up before onCreate() and can be resuming a
worker in this same process while the sweep runs. StagingSweep only collects a
file nothing has written to for 24 hours. Outputs are written continuously and
keep their own mtime fresh; concat_list.txt is the one file written once and then
only read, and a WorkManager attempt is capped by the six-hour foreground-service
budget with retries restarting doWork() from the top, so no attempt can hold a
file still for a day. sweepStaging() also re-reads each timestamp immediately
before deleting, closing the window between listing the directory and acting on
the list -- unlinking an inode a running job still holds open would end with the
job reporting success for a path that no longer exists.
The rule itself is a pure function over (name, lastModifiedMs) pairs and a clock.
Timestamps are values rather than Files so the tests measure the arithmetic --
the grace boundary, and a clock that moved backwards -- rather than the
filesystem's mtime granularity.
Tests cover the tool AND the wiring, because the wiring is where the defect was.
A pure rule test and a Robolectric test of OutputPublisher both stay green when
the discardStaged call is deleted from reset(), which would have made the number
read as coverage of a bug that was still there. So both ViewModels are driven --
through a real WorkManager, to Converted/Joined -- and then asserted on the
filesystem: Start over deletes the staged file; a successful save leaves nothing
to delete twice; a failed save keeps the file and a later reset collects it, which
pins the argued decision above rather than leaving it as a comment. Verified by
deleting the discardStaged line from both reset() methods: 4 of the 6 fail with
"reset() should have discarded exactly the staged file expected:<[...]> but
was:<[]>", and the two save-path tests correctly stay green.
Three things made that reachable, all reusing what was already here:
- Both ViewModels now resolve their publisher through ConversionDependencies,
like the workers already did. They were the only place bypassing the seam.
- MediaProbe joins that seam too. It spawns FFprobe, and FFmpegKit's loader
throws a bare java.lang.Error when the native library is absent -- which its
own `catch (e: Exception)` cannot catch, so every JVM test died on the file
pick. Instrumented tests are unaffected and still get the real probe.
That error path is a LATENT PRODUCTION HAZARD, recorded in the KDoc and
deliberately not fixed here: onInputPicked does not catch it either, so a
missing .so would surface as an uncaught error rather than the "could not read
this file" the code was written to give. It cannot fire on a device that ships
the libraries, so widening MediaProbe's catch to Throwable would change the
pick path on the strength of a condition no user meets. Its own commit.
- reset()'s cleanup dispatcher is a constructor parameter defaulting to
Dispatchers.IO, which makes the delete assertable and states the ordering --
Idle is published synchronously, the delete is dispatched -- as a decision
rather than an accident. @JvmOverloads keeps the single-argument constructor
that viewModel()'s AndroidViewModelFactory looks up reflectively.
androidx-work-testing was already in the catalog and already inside the prerelease
guard via its androidx. group, so it needed no new pinning argument.
Robolectric is added for the one assertion no pure function can make: that the
file is really gone from a real cacheDir. It is PINNED at 4.16.1 and belongs with
ktlint/detekt/jacoco rather than the floating libraries. The prerelease guard in
app/build.gradle.kts only covers androidx., junit and com.arthenica, so
org.robolectric is unguarded and a "4.+" would resolve to 4.17-beta-3; beyond
that, a bump changes which android-all jar the tests execute against, which is the
same "a tool moved under a diff that cannot explain it" failure the linters are
pinned for.
Two things Robolectric needed. testOptions did not exist in this module at all;
it now sets isIncludeAndroidResources so the merged manifest and resource table
reach the JVM tests, and grants --enable-native-access, which Java 25 otherwise
warns about four times per run when Robolectric's native runtime calls
System.load(). And robolectric.properties pins sdk=36: Robolectric defaults to the
manifest's targetSdk of 37, there is no android-all jar for 37, and the class
fails to initialise before any test body runs. 36 is where CI's emulator matrix
already stops, so this does not widen the gap -- API 37 was already a manual check
on the Pixel 10 Pro XL before each release.
Known and left alone: a conversion that fails inside the worker never reaches
Converted, so pendingStaged is never set and any partial output relies on the
sweep alone. reset()'s delete is also fire-and-forget on viewModelScope, so it is
cancelled if the Activity finishes first. The sweep is the backstop for both.

Apply ktlintFormat
Tool output only, no hand edits, so this is safe to read with whitespace diffing off. It is its own commit for exactly that reason: a whole-repo reformat folded into the commit that configured the formatter would have made both unreviewable. What it did, mostly: trailing commas on wrapped argument lists, signatures collapsed onto one line where they fit inside 120 columns, import order, and four genuinely unused imports removed. Unit tests pass unchanged. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |
