VolumedArchiveInStream only works for .7z.001 splits - it rejects RAR
filenames. For multi-part RAR (.partN.rar), use RandomAccessFileInStream
with explicit ArchiveFormat.RAR5/RAR format specification. Auto-detection
with null format can fail for multi-volume RAR archives.

The JVM extractor used RandomAccessFileInStream for multi-part RAR archives,
which only provides a single file stream. 7z-JBinding requires
VolumedArchiveInStream to access additional volume parts via callback.
Added RAR_MULTIPART_RE and RAR_OLDSPLIT_RE patterns to detect multi-volume
RAR archives and route them through VolumedArchiveInStream, fixing
"Archive file can't be opened with any of the registered codecs" errors.

The previous fix blocked ALL multi-part extractions when any item in the
package was pending. Now checks only parts of the SAME archive (by prefix
match on fileName/targetPath), so E01 can extract while E06 downloads.

- findReadyArchiveSets: for .part1.rar, require ALL package items
to be terminal before allowing extraction (prevents premature
extraction when later parts have no targetPath/fileName yet)
- JVM extractor: remove CRCERROR from isPasswordFailure() — only
DATAERROR indicates wrong password. CRCERROR on archives where
7z-JBinding falsely reports encrypted no longer triggers password
cycling.
- looksLikeWrongPassword: remove CRC text matching, keep only
explicit "data error" for encrypted archives.

- Account Manager: table UI with add/remove/check for all 4 providers
(Real-Debrid, Mega-Debrid, BestDebrid, AllDebrid)
- Backend: checkRealDebridAccount, checkAllDebridAccount, checkBestDebridAccount
- Hybrid-Extract fix: check item.fileName for queued items without targetPath,
disable disk-fallback for multi-part archives, extend disk-fallback to catch
active downloads by fileName match (prevents CRC errors on incomplete files)

Scrapes the Mega-Debrid profile page to display username, premium status,
remaining days, and loyalty points. New "Account prüfen" button in Settings > Accounts.

- Encrypt sensitive credentials (tokens, passwords) in backup exports
using AES-256-GCM with PBKDF2 key derivation from OS username
- Backup format v2 with backwards-compatible v1 import
- Show dialog to create non-existent directories when changing
outputDir, extractDir, or mkvLibraryDir settings

Root cause: SevenZip.initSevenZipFromPlatformJAR() was never called, so
native compression codecs (RAR5, LZMA2, etc.) were not loaded. Archives
could be opened (header parsing is pure Java) but all extractSlow() calls
returned UNSUPPORTEDMETHOD because no native decoder was available.
- Add ensureSevenZipInitialized() with lazy init before extraction
- Pass password to extractSlow(outStream, password) for RAR5 compatibility
- Add UNSUPPORTEDMETHOD -> legacy fallback in extractor.ts as safety net

Java's getCanonicalFile() resolves subst drives inconsistently,
causing secureResolve() to falsely block valid filenames. JVM handles
long paths natively so subst is only needed for legacy UnRAR/7z.

The JVM sidecar class files were packed inside app.asar where Java
cannot access them. asarUnpack extracts them to app.asar.unpacked/.
Default backend changed from auto to jvm (no legacy fallback).

- New JVM sidecar (resources/extractor-jvm/) using SevenZipJBinding for
RAR/7z/TAR and Zip4j for ZIP multipart, matching JDownloader 2 stack
- Auto/JVM/Legacy backend modes via RD_EXTRACT_BACKEND env variable
- Fallback to legacy UnRAR/7z when JVM runtime unavailable
- Fix isJvmRuntimeMissingError false positives on valid extraction errors
- Cache JVM layout resolution to avoid repeated filesystem checks
- Route nested ZIP extraction through JVM backend consistently

- setWindowsBackgroundIO (Very Low I/O) now only applied in hybrid mode,
not for all extractions (was causing massive slowdown)
- Hybrid threads changed from -mt1 to half CPU count (e.g. -mt4 on 8-core)
- Move retry count (R9, R22 etc.) from status text to tooltip only
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- normalizeSessionStatuses: reset all queued items to "Wartet" instead of
only checking a few specific patterns (missed Retry, Unrestrict-Fehler etc.)
- Reset completed items with stale extraction status to "Fertig (size)"
- stop(): reset all non-finished items to queued/"Wartet" and packages to queued

- Add disk space check before extraction (aborts if insufficient space)
- Add single-level nested archive extraction (archives inside archives)
- Blacklist .iso/.img/.bin/.dmg from nested extraction
- Set real Windows I/O priority (Very Low) on UnRAR via NtSetInformationProcess
- Reduce UnRAR threads to -mt1 during hybrid extraction
- Fix double episode renaming (s01e01e02 pattern)

Items with transient status texts like Provider-Cooldown, Warte auf
Daten, Verbindungsfehler are reset to "Wartet" when the app restarts,
so they don't show misleading status from a previous session.

- Debounce: simultaneous failures within 2s count as 1 failure
(prevents 8 parallel unrestrict failures from instant-triggering)
- Raise threshold from 8 to 20 consecutive failures before cooldown
- Escalation tiers: 20→30s, 35→60s, 50→120s, 80+→300s

- Pause now aborts active extractions (previously extraction continued
during pause, showing wrong status like Provider-Cooldown)
- Unpause clears provider circuit breaker for fresh start
- Post-processing status checks account for global pause state
- Reduce stall detection timeout from 30s to 15s for faster retry
- Reduce stall retry base delay from 500ms to 300ms

- Add pause check at top of processItem retry loop so items show
"Pausiert" instead of "Provider-Cooldown" when paused
- Lower extraction process priority from BELOW_NORMAL to IDLE
(IDLE_PRIORITY_CLASS on Windows also lowers I/O priority, reducing
disk contention between extraction and active downloads)

- Make saveSettings async to stop blocking the event loop during downloads
- Add 120ms minimum gap for forced state emissions to prevent rapid-fire IPC
- Fix circuit breaker feedback loop: reset failure count after cooldown expires
- Add 120s time-decay for failure counter (transient bursts don't snowball)
- Raise circuit breaker threshold from 5 to 8 consecutive failures
- Stop counting network stalls as provider failures
- Items without a provider only check primary provider cooldown, not all

- New "Jetzt entpacken" right-click option: triggers extraction for
completed packages regardless of paused/stopped state
- Fix 5-10s freeze when pressing Start after Pause: recoverRetryableItems
was calling fs.stat on every item (474+); now only checks failed/completed
- Full IPC pipeline: extractNow in manager, controller, preload, renderer
