Multiple Mega-Debrid accounts can now be configured as login:password
pairs (one per line). When an account hits Fair-Use limits or errors,
the next account is tried automatically.
- New parser module mega-debrid-accounts.ts (parse, ID generation,
masking, serialization)
- Per-account daily limits, usage tracking, enable/disable
- Account rotation with per-mode cooldowns (API failures don't
block Web attempts)
- Backward compatible: existing single megaLogin/megaPassword
is auto-migrated to the new format
- UI: textarea for credentials, account list with masked logins
Follows the existing Debrid-Link multi-key pattern.

Scene releases occasionally use SxxSxx (e.g. s05s01) instead of
SxxExx — the second S is a typo for E. Add a fallback regex to
detect this pattern and correctly interpret it as S05E01.

Sample files like wayne-sample.mkv were renamed by auto-rename which
stripped the -sample suffix. After rename they were indistinguishable
from the main MKV, causing MKV collection to create (2) copies
(e.g. Messiah.Superstar.S01E01...WAYNE (2).mkv at 17 MB alongside
the real 470 MB episode).
Auto-rename now skips files with a "sample" token in their name,
matching the same detection used by MKV collection's sample filter.

During hybrid extraction, files can finish extracting between the
auto-rename scan and MKV-move, causing them to be moved to the MKV
library dir with their original scene names (e.g. awa-diethundermans03e21hd.mkv).
Add a post-MKV-move auto-rename pass on the MKV library directory to
catch these stragglers and rename them to the proper folder-based name.

Folder names with episode ranges like S01E01-E08 (common in season
packs from debrid servers) were returned unchanged as target name,
causing all episodes to get the same filename and producing (2)(3)(4)
suffixes during MKV collection.
- Detect episode ranges (S01E01-E08, S01E01-08) in folder names and
replace them with the source file's specific episode token
- Extend applyEpisodeTokenToFolderName regex to match and replace
full episode ranges instead of only single episode tokens

- Fix episode-token pollution: packageExtraCandidates included ALL item
filenames, causing resolveEpisodeTokenForAutoRename to pick up episode
tokens from unrelated files (e.g. S01E07 from 4sf-...-s01e07 applied
to all hrs-...-101/102/103 files). This also caused (2)(3) MKV
suffixes when multiple files were renamed to the same wrong episode.
Now only the package name (outputDir) is used as extra candidate.
- Fix deferred nested extraction missing abort signal: the nested
extractPackageArchives call in runDeferredPostExtraction did not
receive deferredController.signal, making it unabortable on
stop/cancel/restart.

- Dynamically compute JVM -Xmx based on system RAM instead of hardcoded 32g
- Reduce peak memory during session loading (inline JSON string, skip redundant clone)

- Always force re-download once when both JVM and legacy extractors fail
(suggestRedownload=true), regardless of valid archive signature
- Add autoRecoveredForRedownload Set for loop protection (one attempt per archive)
- Clear loop protection on package reset (clearHybridArchiveState)
- Previous sibling-items check failed when other episodes were already
cleaned up after hybrid extraction
- Lower mini-download retry threshold from 100KB to 5KB

- Retry extraction with 2.5s delay on CRC/password errors (Windows file handle race)
- Improve auto-recovery: force re-download when known password fails (content corruption)
- Expand auto-recovery to wrong_password category for encrypted RAR5
- Add fsync after download for pre-allocated files
- Fix permanent extraction failure loop for archives with valid headers but corrupt content

- Switch JVM GC from SerialGC to G1GC with MaxGCPauseMillis=50
for shorter pause times in long-lived daemon
- Increase JVM heap from 512m/8g to 1g/32g to reduce GC pressure
on systems with plenty of RAM
- Raise hybrid thread cap from floor(cpuCount/2) capped 8
to ceil(cpuCount*0.75) capped 12 — downloads are I/O-bound
and don't need much CPU headroom
- Refresh daemon process priority before each request so hybrid
extraction gets correct CPU priority even if daemon was started
with a different priority level

- Early-exit now also uses raw Content-Length as fallback when
totalBytes is unknown (provider returned fileSize=0)
- Stall handler checks if file is already complete on disk before
deleting and retrying — prevents re-download loop for files that
finished but server delayed closing the connection

- Add scheduler generation counter to prevent stale scheduler from
continuing after stop/start cycle
- Guard processItem stop-abort handler: skip status overwrite when a
new start() has already re-activated the session
- Yield in start() after recoverRetryableItems to let pending abort
handlers complete before evaluating item states
- Add test: rapid stop → disable provider → start must resolve

If the primary extractor (7-Zip) fails with wrong_password/checksum
error on a .rar file, automatically try the alternative extractor
(UnRAR/WinRAR) which handles RAR format natively and more reliably.

Items incorrectly marked as "completed" by the old 50% recovery threshold
persist in the session file across updates. On startup, check all completed
items: if the file on disk is smaller than expected totalBytes, reset to
"queued" so it gets re-downloaded. Also reset items whose files are missing.

Two bugs in findReadyArchiveSets disk-fallback:
1. Failed items were explicitly excluded from the blocking check
(status !== "failed"), so partial downloads with "failed" status
would not block extraction. Now ANY non-completed item blocks.
2. The disk size check was only > 10 KB, allowing 627 MB partial
files of 1001 MB archives to pass. Now requires the file to be
within one allocation unit of the item's expected totalBytes.
Added findItemByDiskPath helper to look up the owning item for a
file on disk and get its expected size.

Item-Recovery incorrectly marked partially downloaded files as "completed"
when the file size was >= 50% of expected size. A 627 MB partial download
of a 1001 MB file (62.7%) would pass the check and trigger hybrid
extraction on incomplete RAR archives.
Fix: require file to be within one allocation unit (4 KB) of the expected
size instead of 50%. Also add a pre-allocation guard: if the file appears
to be at the expected size but downloadedBytes is significantly behind
(< 95%), skip recovery (likely a pre-allocated sparse file from a crash).

Detect items whose targetPath has a " (N)" suffix from the previous
duplicate filename bug and rename them back to the original filename.
This fixes extraction failures for RAR split archives that were
downloaded with (1) suffix before v1.7.19.

Replace shared currentKeyIndex round-robin with sequential scan from
first key. All parallel items now consistently use the same key (e.g.
Key 3) until it hits a quota/error, then all move to Key 4, etc.
Previously, currentKeyIndex was shared across parallel unrestrict calls,
causing items to scatter across keys (3, 5, 7) even when Key 3 still
had capacity.

After restart, reservedTargetPaths (in-memory) was empty so claimTargetPath
could not distinguish between "file belongs to this item" and "file belongs
to another item". The naive fix (allow overwrite if unclaimed) would have
risked overwriting completed files from other items.
Proper fix: restore reservedTargetPaths from persisted session data on init.
This way each item's targetPath is correctly claimed, and claimTargetPath
can safely reuse the item's own file while protecting other items' files.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
When the app restarts (or updates) while downloads are in progress,
partial files remain on disk but reservedTargetPaths (in-memory) is empty.
claimTargetPath treated the unclaimed-but-existing file as a conflict and
appended (1) to the filename, breaking RAR split archive extraction.
Fix: if a file exists on disk but no other item has reserved the path,
allow overwriting instead of creating a duplicate.

- Add "notDebrid", "disabledServerHost", "notFree" as immediate-skip errors
(no 3x retry per key, break to next key instantly like quota errors)
- Add per-key cooldown cache (2 min) so parallel items skip recently-failed keys
instead of all starting at the same broken key
- Set cooldown on quota errors too, preventing repeated checks on exhausted keys

Shelve (15+ failures) now mimics manual stop/start behavior:
- Clears item.provider for fresh provider selection on retry
- Resets provider circuit breaker (providerFailures) for the old provider
- Reduces shelve duration from 5 min to 90s since the issue is stale
provider state, not a timing problem (manual restart works instantly)
Also adds comprehensive session-load logging:
- Logs package/item count on every session file read
- Logs errors when session file parsing fails (was silent before)
- Safety net: if primary session is empty but backup has packages,
automatically restores from backup
- Logs shutdown save with package/item counts
- Logs DownloadManager init state and cleanup policy

The inner unrestrict error handler still called recordProviderFailure()
for hosterNotAvailable errors, causing provider-level cooldown escalation
(up to 180s) even though the issue is hoster-side, not provider-side.
This made auto-retry stall while manual reset worked instantly.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
hosterNotAvailable was added to isTemporaryUnrestrictError which
triggered aggressive provider-level cooldowns (up to 180s) that
blocked ALL items for the affected provider. Since items kept
failing, the cooldown never expired (15-min reset threshold never
reached), causing retries to effectively stall.
Fix: remove hosterNotAvailable from isTemporaryUnrestrictError.
It still gets normal unrestrict retry with item-level backoff
(5s -> 120s) via isUnrestrictFailure, but without provider-wide
cooldown blocking other items.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Move hosterNotAvailable from isPermanentLinkError to
isTemporaryUnrestrictError — hoster being unavailable is usually
transient (overload, maintenance) and should be retried with backoff
instead of immediately failing as "Link ungültig".

Archives with absolute internal paths (e.g. scene groups storing full
Windows paths) fail all password attempts in normal mode at ~98%, then
succeed only after the flat-mode fallback kicks in. Previously every
archive in such a package wasted all password cycles before discovering
flat mode was needed again.
Now the first successful flat-mode extraction sets a package-level flag
so subsequent archives skip the normal loop entirely and go straight to
flat-mode extraction, saving ~4x password attempts per archive.
