v0.7.8

Added

• Dedupe good copies. A series with two valid copies of the same issue
  (two downloads, a scan beside a digital release) had no way to tidy up —
  "Remove duplicates" only covered corrupt copies a good one had replaced.
  It now removes extra good copies too, keeping the best (tagged first, then
  the most pages, then the largest), and says which it kept. Tools → Remove
  duplicate files does the same library-wide, previewing the good-copy part
  to Logs unless you tick the box.
• Tools → Re-check mismatched volumes. Finds series whose files go beyond
  their ComicVine volume's last issue and re-matches them with the improved
  matcher; a clear winner is applied and its files re-linked, the rest are
  left for Fix match.

Fixed

• Files that were clearly on disk showed their issue as missing. Three
  causes, all fixed. Filenames in the Series (Year) NNN (tags) style — a
  common convention for libraries organised by other tools — parsed to no
  issue number at all, so the file could never be tied to its ComicVine issue.
  A ComicInfo tag whose <Number> didn't match ComicVine's numbering blocked
  the link even when the filename was fine; the filename is now tried as well.
  And 001a-style numbers now match ComicVine's 1A. The series page also
  gains an unmatched files panel listing any file in the folder that isn't
  tied to an issue, with the number BackIssue read from it — so the reason is
  visible instead of the file being silently invisible. Rescanning a series
  (or the next library scan) relinks existing files; no re-import needed.
• Auto-match no longer picks a same-name mini over the real run. Matching
  now weighs a volume's issue count against the files you have — a 13-issue
  volume can't be the home of your #14–#163 — and, when the first search
  isn't conclusive, also asks ComicVine for that year's volumes by name
  (common titles have hundreds of volumes and the search stops at 100, so
  the right run could be missing entirely). It also tries the series name
  and year the files themselves carry in their tags — a short legacy row
  ("Jeff") that captured the folder of It's Jeff Infinity Comic now finds
  the real volume. Fix match counts every file on disk, linked or not, so
  the right volume ranks first.
• PDFs were flagged corrupt. A PDF was being verified as if it were a ZIP
  ("not a zip file"); it's now recognised as a PDF, with its page count.
• A completed download with a non-ASCII name could fail to import forever.
  When the download client's reported file can't be read (a name like
  "Blüdwire" mangled across a network mount), the job folder is searched for
  the comic instead; and a release that still can't be read is blocklisted
  rather than re-grabbed on every wanted search.
• Negative issue numbers (#-1 flashback issues) now link.
• Two series rows on one ComicVine volume. A series added straight from
  ComicVine while the folder's own row was matched to the wrong volume left
  two rows — and, once the folder row was re-matched, two copies of every
  file. Matching now folds a twin row into the one being matched (files,
  wanted issues and follows move over), and Tools → Merge duplicate
  series cleans up pairs that already exist.
