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`.

Clear the 35 findings the new tools reported
detekt found 29 and Android lint 6, on a codebase neither had ever seen. Each
one was either fixed or relaxed with the reason written next to it; nothing was
suppressed to make the build quiet.
Fixed, because the tool was right:
- ConversionDependencies constructs Media3Engine, which is @UnstableApi, and
was not marked. Every other type here that touches Media3 propagates the
marker rather than swallowing it with @OptIn, so this one does too. Lint
was the only thing that had ever noticed.
- MediaProbe converted microseconds to milliseconds with a bare 1000, twice,
in a file that also handles a seconds-based duration from a different API.
US_PER_MS and MS_PER_SECOND now say which is which -- that confusion is a
real bug source in media code, not a style question.
- Foreground service types compared SDK_INT against 34 and 35 as raw ints
while the doc comment above spelled the version names out. VERSION_CODES
says it in the code.
- take(3) is a product decision about how many alternatives an error offers.
It means nothing until it is named; MAX_SUGGESTIONS does.
- setProgress(100, ...) is a percentage max, now PERCENT_MAX.
Relaxed, because the rule did not fit:
- The model package is excluded from ReturnCount and CyclomaticComplexMethod
ONLY. It is the decision layer: ConversionRouter.route scores 17 because
the app can give 17 distinct answers to "which engine, and why", each with
its own user-visible reason, and route's own comment records that their
ORDER decides which message is shown. Counting those as complexity measures
how many answers exist, not how hard the code is to follow. Everything else
-- LongMethod, NestedBlockDepth, ComplexCondition -- still applies there.
- A flat `when` used as a lookup table scores a point per entry, so
MediaProbe's demuxer-name to Container map read as complexity 21 with no
nesting and no state. ignoreSingleWhenExpression is the rule's own answer.
- TooGenericExceptionCaught off. MediaProbe, ConversionWorker and ConcatWorker
sit in front of native code that reports a malformed file as anything from
IllegalArgumentException to a bare RuntimeException, undocumented.
Enumerating that list means guessing, and a wrong guess crashes the app on a
file it could have reported as unreadable. SwallowedException stays on, so
these still have to log and handle.
- SI thresholds in the byte formatter, via ignoreNumbers. Each literal sits on
the line with the unit string it belongs to; BYTES_PER_MB would need a Long
and a Double and say nothing the line does not.
- allowedFunctionsPerObject, which the first pass simply missed.
Lint's three version-freshness nags are off. They do not describe this code --
they go red the day someone else publishes a release, which turns a PR red for
something its author cannot see in their diff, and they want the network at
lint time. Upgrades here are deliberate; Kotlin in particular is pinned to AGP's
bundled KGP and is not free to follow the newest release.
UsableSpace is informational rather than disabled, because it is a real finding
that this commit is choosing not to act on. hasSpaceFor reads File.usableSpace,
which ignores reclaimable cache, so the app can refuse a conversion it had room
for. StorageManager.getAllocatableBytes is the better answer, but it changes
when a job is rejected and can throw -- a behaviour change to a safety check,
which deserves its own commit and its own test rather than a drive-by here.
informational keeps it in every lint report instead of hiding it.
Also adds the CI gate and a CLAUDE.md. Coverage is reported and not gated: the
measured baseline is 31% of lines, which is exactly why LibreMail's 0.84 floor
was evidence about LibreMail and not a number to copy.

Give this project the lint and formatting setup LibreMail already has
There was none: no .editorconfig, no static analysis, and CI ran only tests. Style was whatever the IDE happened to do, which is fine until two of them disagree. The split is LibreMail's, because it is the one that avoids arguments between tools: ktlint owns formatting, detekt owns static analysis with its formatting ruleset left off. Neither can contradict the other about the same line. Adapted rather than copied. LibreMail is Gradle 9.6 / JDK 21 with the configuration cache off; this is Gradle 9.5 / JDK 17 with it on, and Kotlin lives under src/main/java rather than src/main/kotlin -- so its plugin versions were evidence, not proof. Verified here before committing: both plugins resolve, ktlint reads src/main/java, and the run stores a configuration cache entry rather than tripping over it. detekt.yml carries only what applies. The Compose relaxations transfer intact -- a @Composable function is legitimately long, PascalCase, and full of dp literals no matter which app it is in. LibreMail's ForbiddenImport guard and its LargeClass exclusions do not: they name an AppLog facade and two test files that exist over there and nowhere here, and config that guards nothing is worse than no config, because the next reader has to work out that it is dead. detekt 2.0 is an alpha. That is not a preference: stable 1.23.x stops at Gradle 8.12 and this project is on 9.5, so there is no other line to be on. Coverage is reported, not gated. A floor needs a measured baseline, and the JVM test stack here is still junit-only -- a number picked before measuring would either fail on day one or mean nothing. Android lint gets warningsAsErrors because the other two tools fail on any finding, and a gate that stays green while its report fills up is not a gate.
