 ## Version History
 
+### 0.4.3
+
+- styled ASS subtitle sources with embedded font attachments are now detected explicitly, keep MKV output, preserve current source font attachments, and reject incompatible sidecar subtitle import
+- attachment descriptors are now treated as source-runtime data instead of pattern schema data, so pattern persistence skips them and source-vs-pattern validation ignores them
+- inspect differences no longer report planned changes for attachment filename/count drift while still showing attachment streams in the stream table
+
+### 0.4.2
+
+- pattern details now show an inline `Show: <quality>` hint next to the quality field when the pattern itself has no stored quality but the selected show does
+- inspect stream tables now show attachment format labels like `TTF` in the codec column and keep attachment language cells blank instead of showing an undefined language
+- ffmpeg damaged-MP3 diagnostics now recognize additional corruption lines such as `invalid new backstep`, keeping them grouped under the `warn-corrupt-mpeg-audio` review summary
+
+### 0.4.1
+
+- `convert` now supports `--copy-video` and `--copy-audio` to keep the selected stream type in copy mode without applying the corresponding reencode flags, filters, or formatting options
+- ffmpeg conversions now monitor diagnostics while the process is running, retry unset AVI packet timestamps once with `-fflags +genpts`, and stop early when a file should be skipped instead of waiting for the full job to finish
+- end-of-run convert summaries now list only ffmpeg findings that still require review, including named remedy identifiers such as `warn-corrupt-mpeg-audio`
+- `upgrade` now finishes by reporting the installed FFX version together with the active bundle branch
+
+### 0.3.1
+
+- debug mode screen titles now append the active Textual screen class name, making screen-specific troubleshooting easier during inspect and edit flows
+- `--cut` again works as a combined flag/option: omitted disables cutting, bare `--cut` applies the default `60,180`, and explicit duration or `START,DURATION` values stay supported
+- H.265 unmux commands no longer force an invalid `-f h265` output format, keeping ffmpeg copy extraction aligned with the required Annex B bitstream filter
+- H.264 encoding now falls back from `libx264` to `libopenh264` with a warning when needed, and the test fixtures use the same encoder fallback so the suite remains portable across ffmpeg builds
+
+### 0.3.0
+
+- inspect and edit screens now refresh nested track and pattern changes more reliably, with inspect-mode tables aligned to the target pattern view shown in the differences pane
+- metadata editing got a follow-up polish pass with clearer ffmpeg notifications, a shared in-screen log pane, safer apply/reload handling, and expanded cleanup and normalization coverage
+- track and asset probing recognize additional codecs, and the modern test suite now covers more metadata-editor, change-set, screen-state, and asset-probe behavior
+- Textual now requires version `8.0` or newer to match the UI APIs used by the current screens
+
+### 0.2.6
+
+- DB-free `ffx edit` workflow for in-place metadata editing via temporary-file rewrite
+- inspect and edit workflows split into dedicated Textual screens with shared media-workflow support
+- Textual tables and row actions now separate raw data from rendered labels to avoid markup leaking into stored metadata
+- responsive screen layout pass, `Esc` back handling, sortable show/inspect tables, and improved edit-screen notifications/toggles
+- application-wide UTF-8 i18n catalogs with language precedence from CLI over config over system over German default
+- metadata normalization extended for localized subtitle titles, ISO language cleanup, and smarter track editor language/title helpers
+
+### 0.2.5
+
+- show-level quality and notes fields
+- pattern-over-show-over-default season-shift resolution with dynamic DB migration loading
+- migration prompt now reports the upgrade path and creates an in-place DB backup before applying schema changes
+- `upgrade --branch <name>` now fetches remote-only branches before switching
+- `unmux` now applies season shifting to subtitle output filenames
+- convert now keeps DB-defined target subtitle dispositions authoritative over sidecar filename disposition flags when a pattern definition exists
+- focused modern tests added around migrations, unmux, upgrade, and subtitle-disposition import precedence
+
 ### 0.2.4
 
 - lightweight CLI commands now stay import-light via lazy runtime loading

+# File Formats
+
+This document captures source-file-format notes that complement the normative
+requirements in `requirements/source_file_formats.md`.
+
+The first documented format is a Matroska source that carries styled ASS/SSA
+subtitle streams together with embedded font attachments.
+
+## Styled ASS In Matroska With Embedded Fonts
+
+These files are typically `.mkv` releases where subtitle rendering quality
+depends on keeping both parts of the subtitle package together:
+
+- one or more subtitle streams with codec `ass`
+- one or more attachment streams that embed font files used by those subtitles
+
+This matters because ASS subtitles are not plain text subtitles in the narrow
+WebVTT sense. They can carry layout, styling, positioning, karaoke, signs, and
+other typesetting effects. If the matching embedded fonts are lost, consumers
+can still see subtitle text but the intended styling and sometimes glyph
+coverage can be degraded.
+
+For FFX this format is special because the ASS subtitle streams should remain
+normally editable and mappable, while the related font attachments should be
+transported unchanged.
+
+## Observed Sample
+
+Assessment date: `2026-04-17`
+
+Observed sample file:
+
+- `tests/assets/boruto_s01e283_ssa.mkv`
+
+Commands used for assessment:
+
+```bash
+ffprobe tests/assets/boruto_s01e283_ssa.mkv
+ffprobe -hide_banner -show_format -show_streams -of json tests/assets/boruto_s01e283_ssa.mkv
+```
+
+Observed stream layout:
+
+| Stream index | Kind | Key details |
+| --- | --- | --- |
+| `0` | video | `codec_name=h264` |
+| `1` | audio | `codec_name=aac`, `language=jpn` |
+| `2` | subtitle | `codec_name=ass`, `language=ger`, default |
+| `3` | subtitle | `codec_name=ass`, `language=eng` |
+| `4`-`13` | attachment | `tags.mimetype=font/ttf`, `.ttf` filenames |
+
+Observed attachment filenames:
+
+- `AmazonEmberTanuki-Italic.ttf`
+- `AmazonEmberTanuki-Regular.ttf`
+- `Arial.ttf`
+- `Arial Bold.ttf`
+- `Georgia.ttf`
+- `Times New Roman.ttf`
+- `Times New Roman Bold.ttf`
+- `Trebuchet MS.ttf`
+- `Verdana.ttf`
+- `Verdana Bold.ttf`
+
+Important probe behavior from the real sample:
+
+- Plain `ffprobe` lists the font streams as `Attachment: none`.
+- Plain `ffprobe` also prints warnings such as `Could not find codec
+  parameters for stream 4 (Attachment: none): unknown codec` and later
+  `Unsupported codec with id 0 for input stream ...`.
+- The JSON produced by `FileProperties.FFPROBE_COMMAND_TOKENS`
+  (`ffprobe -hide_banner -show_format -show_streams -of json`) still exposes
+  the attachment streams clearly through `codec_type="attachment"` and the
+  attachment tags.
+- In that JSON, the attachment streams do not expose `codec_name`.
+
+This last point is important for FFX: robust detection must not depend on
+attachment `codec_name` being present.
+
+## Detection Guidance
+
+Current known indicators for this format are:
+
+- one or more subtitle streams with `codec_type="subtitle"` and
+  `codec_name="ass"`
+- one or more attachment streams with `codec_type="attachment"`
+- attachment tags that identify embedded fonts, especially
+  `tags.mimetype="font/ttf"`
+- attachment filenames that end in `.ttf`
+
+The pattern can vary. FFX should therefore treat the above as a cluster of
+signals rather than an exact signature tied to one file.
+
+Inference from the observed sample plus FFmpeg documentation:
+
+- MIME matching should not be limited to `font/ttf` alone.
+- The Boruto sample uses `font/ttf`.
+- FFmpeg's Matroska attachment example uses
+  `mimetype=application/x-truetype-font` for a `.ttf` attachment.
+- Detection should therefore normalize multiple TTF-like MIME values rather
+  than depend on a single exact string.
+
+## Processing Expectations In FFX
+
+The format-specific requirements live in
+`requirements/source_file_formats.md`. In practical terms, FFX should:
+
+- recognize the ASS-plus-font-attachment pattern even when attachment probe
+  data is incomplete
+- tell the operator that the pattern was detected and that special handling is
+  being used
+- reject sidecar subtitle import for such sources, because converting or
+  replacing these subtitle tracks with ordinary external text subtitles would
+  break the intended subtitle package
+- continue to allow normal manipulation of the ASS subtitle tracks themselves
+- preserve the font attachment streams unchanged
+
+## FFmpeg Notes
+
+Relevant FFmpeg documentation confirms several behaviors that line up with
+FFX's needs:
+
+- FFmpeg documents `-attach` as adding an attachment stream to the output, and
+  explicitly names Matroska fonts used in subtitle rendering as an example.
+- FFmpeg documents attachment streams as regular streams that are created after
+  the mapped media streams.
+- FFmpeg documents `-dump_attachment` for extracting attachment streams, which
+  is useful for debugging or validating a source file's embedded fonts.
+- FFmpeg's Matroska example requires a `mimetype` metadata tag for attached
+  fonts, which is consistent with using attachment tags as detection signals.
+- FFmpeg also notes that attachments are implemented as codec extradata. That
+  helps explain why probe output for attachment streams can look different from
+  ordinary audio, video, and subtitle streams.
+
+Implication for FFX:
+
+- Attachment preservation is not an optional cosmetic feature for this format.
+  It is part of preserving the subtitle package correctly.
+
+## Jellyfin Notes
+
+Jellyfin's documentation also supports keeping this format intact:
+
+- Jellyfin's subtitle compatibility table lists `ASS/SSA` as supported in
+  `MKV` and not supported in `MP4`.
+- Jellyfin notes that when subtitles must be transcoded, they are either
+  converted to a supported format or burned into the video, and burning them in
+  is the most CPU-intensive path.
+- Jellyfin's subtitle-extraction example for `SSA/ASS` first dumps attachment
+  streams and then extracts the ASS subtitle stream, which reflects the real
+  relationship between ASS subtitles and embedded fonts in MKV releases.
+- Jellyfin's font documentation says text-based subtitles require fonts to
+  render properly.
+- Jellyfin's configuration documentation says the web client uses configured
+  fallback fonts for ASS subtitles when other fonts such as MKV attachments or
+  client-side fonts are not available.
+
+Inference from the Jellyfin compatibility tables:
+
+- Keeping this subtitle format in Matroska is the safest interoperability
+  choice for Jellyfin consumers.
+- Converting the subtitle payload to WebVTT would lose styled ASS behavior.
+- Dropping the attachment streams would force client or fallback font
+  substitution and can change appearance or glyph coverage.
