 ## Version History
 
+### 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

 - Capture a compact, project-wide list of optimization candidates after a broad scan of the current FFX codebase, tooling, and requirements.
 
-## Settled
-
-- The biggest near-term wins are in startup cost, repeated subprocess work, repeated database query patterns, and general repo hygiene.
-- This list is intentionally optimization-oriented rather than bug-oriented. Some items below also improve correctness or maintainability, but they were selected because they can reduce runtime cost, operator friction, or iteration overhead.
-- A first modern integration slice now exists under [`tests/integration/subtrack_mapping`](/home/osgw/.local/src/codex/ffx/tests/integration/subtrack_mapping). Remaining test-suite cleanup is now mostly about migrating and shrinking the legacy harness surface under [`tests/legacy`](/home/osgw/.local/src/codex/ffx/tests/legacy).
-- Shared CLI defaults for container/output tokens now live outside [`src/ffx/ffx_controller.py`](/home/osgw/.local/src/codex/ffx/src/ffx/ffx_controller.py), and a focused unit test locks in the lazy-import contract.
-- Helper filename and rich-text utilities now use compiled raw regexes plus translate-based filename filtering, with unit coverage for TMDB suffix rewriting and Rich color stripping.
-- Process resource limiting now has explicit disabled/default states in the CLI and requirements, and combined CPU-plus-niceness wrapping now executes as `cpulimit -- nice -n ... <command>` instead of a less explicit prefix chain.
-- FFX logger setup now reuses named handlers, and fallback logger access no longer mutates handlers in ordinary constructors and helpers.
-- The process wrapper now uses `subprocess.run(...)` with centralized command formatting plus stable timeout and missing-command error mapping.
-- Pattern matching now uses cached compiled regexes plus explicit duplicate-match errors, and pattern creation flows no longer persist zero-track patterns.

-## Shifted Season Status (2026-04-12)
-
-- Current assessment:
-  - The shifted-season subsystem is present end to end and looks feature-complete in shape, but it is not yet hardened.
-  - The storage, TUI CRUD surface, and CLI/TMDB filename application path all exist, so this is no longer a stubbed or half-started area.
-  - The main gap is correctness and direct verification rather than missing surface area.
-
-- Implemented surface confirmed:
-  - Requirements still treat shifted seasons as part of the accepted product surface in [`requirements/project.md`](/home/osgw/.local/src/codex/ffx/requirements/project.md) and [`requirements/architecture.md`](/home/osgw/.local/src/codex/ffx/requirements/architecture.md).
-  - Persistence exists via [`src/ffx/model/shifted_season.py`](/home/osgw/.local/src/codex/ffx/src/ffx/model/shifted_season.py) plus the `Show.shifted_seasons` relationship in [`src/ffx/model/show.py`](/home/osgw/.local/src/codex/ffx/src/ffx/model/show.py).
-  - CRUD logic exists in [`src/ffx/shifted_season_controller.py`](/home/osgw/.local/src/codex/ffx/src/ffx/shifted_season_controller.py).
-  - Textual add/edit/delete flows are wired through [`src/ffx/shifted_season_details_screen.py`](/home/osgw/.local/src/codex/ffx/src/ffx/shifted_season_details_screen.py), [`src/ffx/shifted_season_delete_screen.py`](/home/osgw/.local/src/codex/ffx/src/ffx/shifted_season_delete_screen.py), and the show details table in [`src/ffx/show_details_screen.py`](/home/osgw/.local/src/codex/ffx/src/ffx/show_details_screen.py).
-  - CLI conversion applies season shifts before TMDB lookup and output suffix generation in [`src/ffx/cli.py`](/home/osgw/.local/src/codex/ffx/src/ffx/cli.py).
-
-- Verified current behavior:
-  - `~/.local/share/ffx.venv/bin/python -m unittest discover -s tests/unit -p 'test_*.py'` passed on 2026-04-12: `75` tests in `0.795s`.
-  - That run emitted `ResourceWarning` messages for unclosed SQLite connections, so the suite is green but not perfectly clean.
-  - There is almost no direct shifted-season coverage in the modern tests:
-    - [`tests/unit/test_cli_rename_only.py`](/home/osgw/.local/src/codex/ffx/tests/unit/test_cli_rename_only.py) stubs `ShiftedSeasonController` rather than exercising it.
-    - [`tests/unit/test_screen_support.py`](/home/osgw/.local/src/codex/ffx/tests/unit/test_screen_support.py) only verifies controller bootstrap wiring.
-  - Net effect: the subsystem is integrated, but its core rules are effectively untested by the current modern suite.
-
-- Reproduced correctness gaps:
-  - Overlap validation is broken in [`src/ffx/shifted_season_controller.py:41`](/home/osgw/.local/src/codex/ffx/src/ffx/shifted_season_controller.py:41) because `getOriginalSeason` is compared as a method object instead of being called.
-  - Reproduction on 2026-04-12 with a temp SQLite DB:
-    - Added `S1 E1-E10`.
-    - `checkShiftedSeason(...)` incorrectly returned `True` for overlapping `S1 E5-E15`.
-    - `addShiftedSeason(...)` then stored the overlapping row successfully.
-  - `updateShiftedSeason(...)` in [`src/ffx/shifted_season_controller.py:93`](/home/osgw/.local/src/codex/ffx/src/ffx/shifted_season_controller.py:93) does not enforce episode ordering, so an invalid range like `first_episode=20`, `last_episode=10` was accepted in the same reproduction.
-  - Because [`src/ffx/shifted_season_controller.py:213`](/home/osgw/.local/src/codex/ffx/src/ffx/shifted_season_controller.py:213) returns the first matching sibling and [`src/ffx/shifted_season_controller.py:163`](/home/osgw/.local/src/codex/ffx/src/ffx/shifted_season_controller.py:163) applies no explicit ordering, overlapping rows would also make runtime shifting ambiguous.
-
-- Progress summary:
-  - Good progress:
-    - The subsystem exists across requirements, schema, UI, and conversion flow.
-    - It appears fully integrated into the show-editing workflow rather than parked as dead code.
-  - Incomplete progress:
-    - Validation logic is not trustworthy yet.
-    - Modern tests do not currently protect the subsystem's real behavior.
-    - User-facing error feedback in the shifted-season screens still has placeholder `#TODO: Meldung` branches.
-
-- Recommended next slice:
-  1. Add direct controller tests for overlap rejection, episode-order validation, and `shiftSeason(...)` selection behavior.
-  2. Fix `checkShiftedSeason(...)` and add the same range/order validation to `updateShiftedSeason(...)`.
-  3. Make sibling selection deterministic or enforce non-overlap strongly enough that ordering no longer matters in practice.
-  4. Add at least one focused integration test that proves a stored shifted season changes TMDB lookup and/or generated filename numbering during conversion.

+# 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.

+# Metadata Editor
+
+This file defines the requirements for a database-free interactive metadata
+editor command derived from the current file-inspection UI.
+
+Feasibility from the current codebase: yes, with a moderate refactor.
+
+The strongest reusable pieces already exist:
+
+- `ffprobe`-backed media probing through `FileProperties` and `MediaDescriptor`
+- descriptor-level metadata and disposition mutation through `MediaDescriptor`
+  and `TrackDescriptor`
+- diff and ffmpeg token generation through `MediaDescriptorChangeSet`
+- stream-copy remux execution through `FfxController` with `VideoEncoder.COPY`
+- reusable tag and track edit dialogs in the Textual UI
+
+The main missing pieces are:
+
+- a CLI bootstrap path that does not initialize SQLite
+- a probe-only path that does not instantiate database-backed controllers
+- a clean separation between original file state and editable draft state
+- a safe temporary-output and replace workflow for writing changes back to the
+  same file path
+
+## Scope
+
+- One new command: `ffx edit <file>`
+- One-file interactive editing through a Textual screen derived from
+  `MediaDetailsScreen`
+- Editing container-level metadata and per-stream metadata already visible in
+  the application
+- Editing stream dispositions that are represented as metadata-like output
+  state, especially `default` and `forced`
+- Writing the result back to the original file path through a temporary output
+  file and replace step
+
+## Out Of Scope
+
+- SQLite reads, writes, migrations, or pattern matching
+- TMDB lookups, show selection, pattern selection, or shifted-season logic
+- Batch editing multiple files in one command invocation
+- Video or audio transcoding
+- Container changes, filename changes, or rename workflows
+- Stream add, stream delete, stream reorder, or stream substitution from
+  external files in the first release
+- Editing technical stream identity such as codec, stream type, source index,
+  or audio layout in the first release
+- Chapter editing
+
+## Terms
+
+- `baseline descriptor`: immutable in-memory representation of the file as last
+  probed from disk
+- `draft descriptor`: mutable in-memory representation of the desired output
+  state
+- `edit mode`: the database-free TUI mode used by `ffx edit`
+- `planned changes`: user-visible summary of the differences between baseline
+  and draft plus any configured cleanup actions
+- `temporary output file`: the write target used before replacing the original
+  file path
+
+## Rules
+
+- `METADATA_EDITOR-0001`: The system shall provide a command `ffx edit <file>`
+  that requires exactly one existing media file path and opens an interactive
+  Textual editor for that file.
+- `METADATA_EDITOR-0002`: `ffx edit` shall not initialize SQLite, shall not
+  open the configured database file, shall not prompt for database migration,
+  and shall not instantiate any controller that depends on `context['database']`.
+- `METADATA_EDITOR-0003`: `ffx edit` may still read configuration and logging
+  settings from `~/.local/etc/ffx.json`, but any global database option shall
+  have no effect on this command's behavior.
+- `METADATA_EDITOR-0004`: Edit mode shall be derived from the current
+  `MediaDetailsScreen` behavior and layout where practical, but all DB-only UI
+  elements and actions such as show selection, pattern input, and pattern CRUD
+  actions shall be hidden, disabled, or replaced.
+- `METADATA_EDITOR-0005`: Edit mode shall keep the baseline descriptor and the
+  draft descriptor as separate objects. Editing actions shall mutate only the
+  draft descriptor until the operator explicitly applies changes.
+- `METADATA_EDITOR-0006`: The application shall keep raw metadata values
+  separate from rendered labels. Rich or Textual markup may be used for
+  presentation, but it shall never be stored in descriptor state, reused as
+  source data, or written into the media file.
+- `METADATA_EDITOR-0007`: The planned-changes view shall compare the baseline
+  descriptor with the draft descriptor using `MediaDescriptorChangeSet` or an
+  equivalent descriptor-diff mechanism. It shall no longer mean `file -> db`.
+- `METADATA_EDITOR-0008`: The editor shall support container-tag add, edit, and
+  delete operations on the draft descriptor.
+- `METADATA_EDITOR-0009`: The editor shall support per-stream metadata edit
+  operations on the draft descriptor, including at least language, title, and
+  arbitrary stream tag key-value pairs.
+- `METADATA_EDITOR-0010`: The editor shall support setting and clearing
+  `default` and `forced` dispositions in the draft descriptor, while enforcing
+  that there is at most one `default` and at most one `forced` stream per track
+  type.
+- `METADATA_EDITOR-0011`: The first released editor scope shall treat technical
+  stream structure as immutable. A user shall not be able to change stream
+  count, output order, codec, track type, audio layout, or source-index
+  mapping through `ffx edit`.
+- `METADATA_EDITOR-0012`: The track-edit UI used in edit mode shall therefore
+  expose only metadata fields and supported disposition fields. Structural
+  fields that are editable in pattern-authoring workflows shall be read-only or
+  absent in edit mode.
+- `METADATA_EDITOR-0013`: The command shall write changes through an ffmpeg
+  stream-copy remux workflow only. No transcoding shall be performed as part of
+  `ffx edit`.
+- `METADATA_EDITOR-0013A`: The ffmpeg invocation used by `ffx edit` shall map
+  all source streams with `-map 0` and shall copy all mapped streams with a
+  single `-c copy`. It shall not emit conversion-style per-stream `-map` or
+  `-c:*` options that could drop, reorder, or transcode streams during a
+  metadata-only edit.
+- `METADATA_EDITOR-0014`: Because ffmpeg cannot rewrite the source file in
+  place, `ffx edit` shall write to a temporary output file on the same
+  filesystem as the source file and shall replace the original path only after
+  ffmpeg reports success.
+- `METADATA_EDITOR-0015`: The temporary output path shall preserve the original
+  container type and file extension. The feature shall not silently change the
+  container or extension during a metadata-only edit.
+- `METADATA_EDITOR-0016`: If the rewrite step fails, the original file shall
+  remain untouched. The system shall not leave the user with a partially
+  replaced source file.
+- `METADATA_EDITOR-0017`: After a successful replace, the application shall
+  reprobe the rewritten file, refresh the baseline descriptor from disk, reset
+  the draft state to that fresh baseline, and clear the dirty state.
+- `METADATA_EDITOR-0018`: Edit mode shall track whether unsaved draft changes
+  exist and shall require confirmation before dismissing the screen or quitting
+  the app when such changes would be lost.
+- `METADATA_EDITOR-0019`: Edit mode shall not inject conversion-only encoding
+  metadata such as encoder quality or preset markers.
+- `METADATA_EDITOR-0020`: Signature-tag behavior shall be explicit for
+  metadata-only editing. The default behavior shall not add a misleading
+  recoding-style signature to a file that was only remuxed for metadata
+  updates.
+- `METADATA_EDITOR-0021`: Configured metadata-removal rules from the local
+  configuration shall be surfaced clearly in the UI and in the planned-changes
+  view. If those rules are applied during save, the operator shall be able to
+  tell that the file will be cleaned in addition to any manual edits.
+- `METADATA_EDITOR-0022`: Edit mode shall provide an in-screen operator toggle
+  for config-driven cleanup so a user can switch between pure manual metadata
+  edits and metadata edits plus configured tag cleanup without leaving the
+  editor.
+- `METADATA_EDITOR-0023`: The existing global `--dry-run` behavior shall apply
+  to `ffx edit`. In dry-run mode the command shall not replace the original
+  file and shall expose the planned write operation clearly enough for the user
+  to understand what would happen.
+- `METADATA_EDITOR-0024`: Every ffmpeg invocation performed by `ffx edit`
+  shall be surfaced to the operator as a notification in the edit UI.
+- `METADATA_EDITOR-0025`: When application verbosity is greater than zero, the
+  notification for an `ffx edit` ffmpeg invocation shall include the concrete
+  ffmpeg command line.
+
+## Acceptance
+
+- `ffx edit /path/to/file.mkv` opens successfully on a workstation where the
+  configured database is missing, empty, incompatible, or intentionally
+  inaccessible.
+- Opening a file in edit mode does not trigger database bootstrap or migration
+  prompts.
+- A user can change a container tag, save, and see the rewritten file at the
+  same path with the updated metadata.
+- A user can change a stream title or language, save, and see the rewritten
+  file at the same path with the updated stream metadata.
+- A user can change `default` or `forced` on a track, save, and see the
+  rewritten file at the same path with the updated dispositions.
+- The planned-changes view reflects manual edits relative to the original file
+  and, when enabled, any configured cleanup removals.
+- No rendered Rich or Textual color markup appears in the saved file metadata.
+- Saving metadata with files that contain PGS subtitle tracks or other
+  non-text subtitle codecs preserves those streams instead of dropping them.
+- If ffmpeg fails while saving, the original file remains present and readable
+  at the original path.
+- In dry-run mode, the original file remains untouched.
+
+## Current Code Fit
+
+- Good fit:
+  - `FfxController.runJob(...)` already has a `VideoEncoder.COPY` path that
+    can remux streams and apply metadata and disposition tokens.
+  - `MediaDescriptorChangeSet` already computes container-tag, stream-tag, and
+    disposition differences and can generate ffmpeg metadata tokens.
+  - `TagDetailsScreen` and `TrackDetailsScreen` already provide reusable edit
+    dialogs for draft state.
+  - `PatternDetailsScreen` already demonstrates add, edit, and delete flows for
+    tags and tracks in a draft-first UI.
+- Refactor required:
+  - `ffx` CLI initialization currently creates a database context for all
+    non-lightweight commands, so `edit` needs its own DB-free bootstrap path.
+  - `FileProperties` currently instantiates `PatternController` eagerly, so
+    probing must be split from pattern matching or made lazy.
+  - `MediaDetailsScreen` currently assumes `command == 'inspect'` and mixes
+    file state with database-backed target-pattern state.
+  - `MediaDetailsScreen` currently mutates the probed source descriptor
+    directly. Edit mode needs an immutable baseline descriptor and a separate
+    mutable draft descriptor.
+  - `TrackDetailsScreen` currently exposes structural fields that are valid for
+    pattern authoring but too dangerous for metadata-only file editing.
+
+## Risks
+
+- Container-level metadata support differs across formats, so some requested tag
+  changes may not round-trip identically through ffmpeg for every supported
+  container.
+- The existing metadata-removal implementation is conversion-oriented and may
+  remove tags more aggressively than a user expects from a manual editor unless
+  cleanup policy is made explicit.
+- The current codebase lacks a dedicated descriptor clone API, so draft-state
+  separation should be implemented deliberately instead of via accidental shared
+  references.
+- Replacing a file path with a temporary output changes inode identity, so any
+  future requirement around preserving timestamps, hard links, or extended
+  attributes would need additional explicit handling.

+# Source File Formats
+
+This file defines source-file-format-specific processing requirements for FFX.
+It is intended to grow as additional relevant source file types are identified.
+
+The first covered format is Matroska media that contains styled ASS/SSA
+subtitle streams together with embedded font attachments.
+
+## Scope
+
+- Detecting source files that use ASS subtitle streams together with embedded
+  font attachments needed for correct rendering.
+- Defining the required `ffx convert` behavior when this format is present.
+- Preserving the required attachment streams during conversion.
+- Keeping normal subtitle-track manipulation behavior for the ASS subtitle
+  tracks themselves.
+
+## Out Of Scope
+
+- General subtitle behavior for sources that do not carry this pattern.
+- A complete catalog of all source file formats FFX may support later.
+
+## Terms
+
+- `styled ASS source`: a source media file that contains one or more subtitle
+  streams with `codec_type="subtitle"` and `codec_name="ass"` together with
+  one or more font-bearing attachment streams.
+- `font attachment`: an attachment stream whose metadata identifies a font
+  payload, commonly through `tags.mimetype` and attachment filename metadata.
+- `external subtitle feed`: subtitle tracks supplied from separate subtitle
+  files through the existing subtitle-import path.
+- `special attachment subtracks`: the embedded font attachment streams that
+  belong to the styled ASS source pattern.
+
+## Rules
+
+- `SOURCE_FILE_FORMATS-0001`: The system shall recognize the styled ASS source
+  pattern.
+- `SOURCE_FILE_FORMATS-0002`: Recognition shall not depend on fixed stream
+  counts, fixed stream indices, or one exact attachment count.
+- `SOURCE_FILE_FORMATS-0003`: Recognition shall use the best available ffprobe
+  signals. For known subtitle streams this includes
+  `codec_type="subtitle"` together with `codec_name="ass"`.
+- `SOURCE_FILE_FORMATS-0004`: Recognition of the special attachment subtracks
+  shall use attachment-oriented signals such as `codec_type="attachment"` and
+  font-identifying metadata such as `tags.mimetype="font/ttf"` when present.
+- `SOURCE_FILE_FORMATS-0005`: Recognition shall tolerate known ffprobe
+  variation in attachment reporting, including files where attachment streams
+  do not expose a `codec_name` but do expose `codec_type="attachment"` and
+  font-identifying tags.
+- `SOURCE_FILE_FORMATS-0006`: When attachment metadata varies across files,
+  detection shall not depend on one exact MIME string alone. Detection shall
+  be written so the known pattern can vary while still recognizing font
+  attachments.
+- `SOURCE_FILE_FORMATS-0007`: When the styled ASS source pattern is detected,
+  `ffx convert` shall emit an operator-facing message that reports the
+  detection and hints that special subtitle preservation handling is being
+  applied.
+- `SOURCE_FILE_FORMATS-0008`: When the styled ASS source pattern is present on
+  the source file, `ffx convert` shall not process an external subtitle feed.
+  The command shall stop before conversion and report an error that explains
+  that separate subtitle-file import is incompatible with this source format.
+- `SOURCE_FILE_FORMATS-0009`: Normal manipulation of the ASS subtitle streams
+  themselves shall continue to work through the usual selection, ordering,
+  metadata, language, title, and disposition handling paths.
+- `SOURCE_FILE_FORMATS-0010`: The special attachment subtracks shall be
+  preserved in the target media file as-is rather than transcoded,
+  regenerated, or replaced from external sources.
+- `SOURCE_FILE_FORMATS-0011`: Preserving the special attachment subtracks
+  as-is includes retaining the attachment payload and the attachment metadata
+  required by consumers, especially attachment filename and mimetype
+  information.
+- `SOURCE_FILE_FORMATS-0012`: This file shall remain the extension point for
+  additional source-file-format contracts as FFX adds support for more special
+  source formats.
+
+## Acceptance
+
+- A source file matching the observed pattern of embedded ASS subtitles plus
+  font attachments is recognized even when the attachment streams do not carry
+  a `codec_name`.
+- `ffx convert` output contains a clear detection message before the actual
+  conversion work proceeds.
+- If external subtitle import is requested for such a source file, the command
+  fails fast with an explicit error instead of mixing sidecar subtitles into
+  the job.
+- Existing manipulation of the ASS subtitle tracks still works for metadata,
+  titles, languages, ordering, and dispositions.
+- The output media preserves the required font attachment streams and their
+  identifying metadata needed by downstream media players.
