+
+# ErsatzTV Channel Management
+
+Container: `ersatztv` | Port: `8409` | IP: `172.16.238.11` (may change on restart)
+Web UI: internal only (`http://localhost:8409` via SSH)
+SQLite DB: `~/downloadswarm/ersatztv/ersatztv.sqlite3` on jazz (owned by root — use `sudo sqlite3`)
+Image: `ghcr.io/ersatztv/ersatztv:latest` (v26.3.0, repo archived Feb 2026)
+
+## Architecture
+
+ErsatzTV uses **MediatR + Blazor** (not REST for mutations). The REST API is limited:
+- **GET endpoints**: channels, collections, schedules, playouts, shows, movies, artists, ffmpeg profiles, health, search, watermarks
+- **POST endpoints**: library scan, playout reset, show scan
+- **No REST CRUD for channels/collections/schedules** — must use SQLite DB directly
+
+## REST API
+
+```bash
+# Via docker exec
+docker exec ersatztv curl -s http://localhost:8409/api/ENDPOINT
+```
+
+### Read Endpoints (GET)
+```
+/api/channels              # List channels
+/api/collections            # List collections
+/api/schedules              # List schedules
+/api/playouts               # List playouts
+/api/shows                  # List shows
+/api/movies                 # List movies
+/api/artists                # List artists
+/api/search                 # Search items
+/api/ffmpeg/profiles        # FFmpeg profiles
+/api/watermarks             # Watermarks
+/iptv/channels.m3u          # M3U playlist (for Jellyfin)
+/iptv/xmltv.xml             # XMLTV guide data
+```
+
+### Mutation Endpoints (POST)
+```bash
+# Library scan
+POST /api/libraries/{id}/scan
+
+# Scan single show
+POST /api/libraries/{id}/scan-show \
+  -H "Content-Type: application/json" -d '{"ShowTitle":"Name","DeepScan":false}'
+
+# Reset channel playout (rebuilds schedule)
+POST /api/channels/{channelNumber}/playout/reset
+```
+
+## SQLite DB Operations
+
+```bash
+# Read queries (safe while running, WAL mode)
+sudo sqlite3 ~/downloadswarm/ersatztv/ersatztv.sqlite3 "QUERY"
+
+# Write queries — stop container first
+docker stop ersatztv
+sudo sqlite3 ~/downloadswarm/ersatztv/ersatztv.sqlite3 "QUERY"
+docker start ersatztv
+```
+
+### Key Queries
+```sql
+-- List channels
+SELECT Id, Number, Name FROM Channel ORDER BY CAST(Number AS INTEGER);
+
+-- List collections with item counts
+SELECT c.Id, c.Name, COUNT(ci.Id) as items FROM Collection c LEFT JOIN CollectionItem ci ON ci.CollectionId = c.Id GROUP BY c.Id;
+
+-- List schedules
+SELECT Id, Name FROM ProgramSchedule;
+
+-- Playout (channel-schedule links)
+SELECT p.Id, c.Number, c.Name, ps.Name as Schedule FROM Playout p JOIN Channel c ON p.ChannelId = c.Id LEFT JOIN ProgramSchedule ps ON p.ProgramScheduleId = ps.Id;
+
+-- Media counts
+SELECT 'Shows' as type, COUNT(*) FROM Show UNION ALL SELECT 'Movies', COUNT(*) FROM Movie UNION ALL SELECT 'Episodes', COUNT(*) FROM Episode UNION ALL SELECT 'MusicVideos', COUNT(*) FROM MusicVideo;
+
+-- Jellyfin source
+SELECT jms.Id, jc.Address, jms.ServerName FROM JellyfinMediaSource jms JOIN JellyfinConnection jc ON jc.JellyfinMediaSourceId = jms.Id;
+
+-- Library sync status
+SELECT l.Id, l.Name, l.MediaKind, jl.ShouldSyncItems FROM Library l JOIN JellyfinLibrary jl ON jl.Id = l.Id;
+```
+
+### Channel Setup Workflow (DB)
+
+**Show-specific channel** (single TV show, shuffled):
+```sql
+-- 1. Schedule
+INSERT INTO ProgramSchedule (Id, FixedStartTimeBehavior, KeepMultiPartEpisodesTogether, Name, RandomStartPoint, ShuffleScheduleItems, TreatCollectionsAsShows)
+VALUES (<id>, 0, 0, '<name>', 1, 0, 1);
+-- 2. Schedule item (CollectionType=1 for Show, PlaybackOrder=3 for Shuffle)
+INSERT INTO ProgramScheduleItem (Id, CollectionType, FillWithGroupMode, GuideMode, "Index", MarathonGroupBy, MarathonShuffleGroups, MarathonShuffleItems, MediaItemId, PlaybackOrder, ProgramScheduleId)
+VALUES (<id>, 1, 0, 0, 0, 0, 0, 0, <show_id>, 3, <schedule_id>);
+INSERT INTO ProgramScheduleOneItem (Id) VALUES (<item_id>);
+-- 3. Channel
+INSERT INTO Channel (Id, Categories, FFmpegProfileId, FallbackFillerId, "Group", IdleBehavior, IsEnabled, MirrorSourceChannelId, MusicVideoCreditsMode, MusicVideoCreditsTemplate, Name, Number, PlayoutMode, PlayoutOffset, PlayoutSource, PreferredAudioLanguageCode, PreferredAudioTitle, PreferredSubtitleLanguageCode, ShowInEpg, SongVideoMode, SortNumber, StreamSelector, StreamSelectorMode, StreamingMode, SubtitleMode, TranscodeMode, UniqueId, WatermarkId)
+VALUES (<id>, '', 1, NULL, '<category>', 0, 1, NULL, 0, NULL, '<name>', '<number>', 0, NULL, 0, NULL, NULL, 'eng', 1, 0, <number>.0, NULL, 0, 4, 2, 0, lower(hex(randomblob(4)))||'-'||lower(hex(randomblob(2)))||'-4'||substr(lower(hex(randomblob(2))),2)||'-'||lower(hex(randomblob(2)))||'-'||lower(hex(randomblob(6))), 1);
+-- 4. Playout
+INSERT INTO Playout (Id, ChannelId, ProgramScheduleId, ScheduleKind, Seed)
+VALUES (<id>, <channel_id>, <schedule_id>, 0, abs(random()) % 1000000);
+```
+
+**Collection-based channel** (multiple shows, shuffled):
+```sql
+-- 1. Collection + items (MediaItemId = Show.Id)
+INSERT INTO Collection (Id, Name, UseCustomPlaybackOrder) VALUES (<id>, '<name>', 0);
+INSERT INTO CollectionItem (CollectionId, MediaItemId) VALUES (<coll_id>, <show_id>);
+-- 2. Schedule (same as above but CollectionType=0, CollectionId set instead of MediaItemId)
+INSERT INTO ProgramScheduleItem (Id, CollectionId, CollectionType, ..., PlaybackOrder, ProgramScheduleId)
+VALUES (<id>, <coll_id>, 0, ..., 3, <schedule_id>);
+-- 3-4. Channel + Playout same as show-specific
+```
+
+After creating: `POST /api/channels/{number}/playout/reset`

+
+## FFmpeg & Hardware
+
+- QSV (Intel Quick Sync) hardware acceleration
+- Resolution: 1920x1080, H264, AAC stereo
+- Device: `/dev/dri` passed through
+- HardwareAccelerationKind: 0=None, 1=Qsv, 2=Nvenc, 3=Vaapi, 4=VideoToolbox, 5=Amf
+
+## Jellyfin Integration
+
+- Secrets: `/config/jellyfin-secrets.json` (`{"Address":"http://jellyfin:8096","ApiKey":"978033be716d46678a5d3c54ae0e0ff9"}`)
+- Libraries: Movies(10), TV Shows(11), Music Videos(8), Standup(9)
+- `JellyfinLibrary.ShouldSyncItems` must be `1` for scans to work
+
+## Gotchas
+
+- DB owned by root — always use `sudo sqlite3`
+- WAL mode: reads OK while running, stop container for writes
+- No REST API for channel/collection/schedule CRUD — DB scripting only
+- Secrets file uses PascalCase JSON (`Address`, `ApiKey`)
+- Scanner is separate binary (`ErsatzTV.Scanner`) — check with `docker top ersatztv | grep Scanner`
+- EF TPT inheritance: `ProgramScheduleItem` has subtype tables (`ProgramScheduleOneItem`, etc.) — MUST insert into subtype table
+- External URL logos work for M3U but NOT for watermark burn-in (code checks `File.Exists()`)
+- `/api/health` returns Blazor HTML, not JSON — use `/api/channels` to verify API
+- PlaybackOrder enum: 3=Shuffle, 6=SeasonEpisode (use 3 for all channels)
+- CollectionType enum: 0=Collection, 1=Show (direct show reference via MediaItemId)
+- SubtitleMode: 0=None, 2=Burn-in. Set to 2 with PreferredSubtitleLanguageCode='eng' for non-music channels
+- MediaItem.State: 0=Normal, 1=FileNotFound — clean up state=1 items by deleting cascading deps
+- ProgramSchedule required NOT NULL columns: FixedStartTimeBehavior, KeepMultiPartEpisodesTogether, RandomStartPoint, ShuffleScheduleItems, TreatCollectionsAsShows
+- Channel required NOT NULL columns: SongVideoMode (set 0), plus all standard columns (see Channel table schema)
+- After schedule changes, rebuild playout: `POST /api/channels/{number}/playout/reset`
+- Playout `ScheduleKind` must be `1` (not `0`/None) — `0` causes "Cannot build playout type None" error
+- M3U `tvg-logo` URLs hardcode `http://localhost:8409` — Jellyfin can't fetch these from inside its container. Fix by downloading logos from ETV and base64-uploading to Jellyfin (see `docs/Docker/ErsatzTV.md` for script). Tracked in issue #171
+- Repo archived Feb 2026, v26.3.0 is final stable version. Maintainer welcomes forks

+POST /Library/Refresh               # Trigger full library scan
+POST /Items/{id}/Refresh            # Refresh single item metadata

+GET  /Users/{userId}                # User details
+```
+
+## Library IDs
+
+Check with: `curl -s -H "X-Emby-Token: TOKEN" http://localhost:8096/Library/VirtualFolders`
+
+## Live TV
+
+- **ErsatzTV** (channels <1000): M3U `http://ersatztv:8409/iptv/channels.m3u`, XMLTV `http://ersatztv:8409/iptv/xmltv.xml`
+- **Dispatcharr** (channels 1000+): IPTV stream manager on port 9191, separate tuner
+- Configured in Jellyfin Admin > Live TV
+- Guide refresh task ID: `bea9b218c97bbf98c5dc1303bdb9a0ca` — trigger via `POST /ScheduledTasks/Running/{id}`
+- **Logo fix after guide refresh**: ErsatzTV logos break (aspect ratio=0) because M3U uses `localhost:8409`. Fix script in `docs/Docker/ErsatzTV.md` downloads from ETV and base64-uploads to `POST /Items/{id}/Images/Primary` (body = base64, Content-Type = image/png)
+- **Image upload format**: Jellyfin expects base64-encoded body (NOT raw binary) for `POST /Items/{id}/Images/Primary`
+
+## Gotchas
+
+- **Passwords**: `coup1802` (NOT `ded89Lm4`) — Jellyfin has native auth, no Authelia
+- Auth header is `X-Emby-Token` (Jellyfin is an Emby fork)
+- Music videos are typed as "Movie" in Jellyfin
+- Music library at `/data/music` maps to `/mnt/media/music_videos` on host (not actual music)
+- Items return 404 on stream if source volume is unmounted
+- Jellyfin preserves item IDs across restarts unless files are renamed
+- Full library scan can take a long time — prefer targeted `/Items/{id}/Refresh`
+- `ffprobe` available in container for checking media streams: `docker exec jellyfin ffprobe -v quiet -print_format json -show_streams FILE`

@@ -4,6 +4,214 @@ All notable changes to this project will be documented in this file.
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 
 ## [Unreleased]
+### Changed
+- Remove BugSnag error reporting integration
+- Remove developer's personal Trakt API key
+  - Users who want to continue to use Trakt must create an API app and set the `Client ID` as the environment variable `TRAKT__CLIENTID`
+
+### Fixed
+- Support adding trakt lists using `app.trakt.tv` domain (instead of just `trakt.tv`)
+
+## [26.3.0] - 2026-02-24
+### Added
+- Add log warnings when actual transcoding speed is potentially insufficient to support smooth playback
+  - Log messages will include media item id, channel number and transcoding speed
+- Add UI language setting to **Settings** > **UI**
+  - A small number of translations have been added for `Português (Brasil)` and `Polski`
+  - Translation contributions are always welcome!
+- Add `Troubleshoot` button to playout details table to show info that may be helpful in determining the source of a playout item
+  - Classic schedule info includes schedule, schedule item, scheduler, filler, playback order, random seed, collection index
+  - Block schedule info includes block, block item, playback order, random seed, collection index
+  - E.g. items with the same random seed are part of the same shuffle
+- Add channel setting `Slug Seconds`
+  - This controls how many (optional) seconds of black video and silent audio to insert between *every* playout item
+  - This will drift playback from the wall clock as slugs are not scheduled in the playout, but are inserted dynamically during playback
+  - If this feature turns out to be popular, methods to correct the drift may be investigated
+- Add `ETV_INSTANCE_ID` environment variable to disambiguate EPG data from multiple ErsatzTV instances
+  - When set, the value will be used in channel identifiers before the final `.ersatztv.org`
+- Show warning message when selecting audio format `aac (latm)` for general streaming use when it is only intended for DVB-C
+
+### Changed
+- Move dark/light mode toggle to **Settings** > **UI**
+- Use latest (non-deprecated) authorization method with Jellyfin API
+- Replace direct Discord links with new contact page https://ersatztv.org/contact which also includes other options like Matrix
+- Lower GOP size and keyframe interval from four seconds to two seconds in accordance with HLS2 draft spec recommendations
+
+### Fixed
+- Improve stability of playback orders `Shuffle` and `Shuffle in Order` over time
+- Fix Trakt list sync
+- Fix some cases of QSV audio/video desync when *not* seeking by using software decode
+  - This only applies to content that *might* be problematic (using a heuristic)
+- NVIDIA: force software decode of 10-bit h264 content since hardware decode is unsupported by ffmpeg until version 8
+- Graphics engine: fix stream seek value used throughout graphics engine
+  - This should fix loading EPG data when used with chapters/mid-roll
+  - This should also fix graphics element visibility when using start_seconds on content with chapters/mid-roll
+  - This bug was caused by stream seek including the playout item in-point (the chapter start time)
+    - Stream seek should only be non-zero when first joining a channel (i.e. in the middle of a playout item or chapter)
+
+## [26.2.0] - 2026-02-02
+### Added
+- Channel stream selector: add zero-based culture-specific `day_of_week` to `content_condition`, for example:
+  - en-US can match sunday using `day_of_week = 0`
+  - fr-FR can match sunday using `day_of_week = 6`
+  - As a complete example, to match Saturday from 9pm (inclusive) to 11pm (exclusive), based on content start time
+    - `content_condition: day_of_week = 6 and (time_of_day_seconds >= 75600 and time_of_day_seconds < 82800)`
+- Add `Pad Mode` to ffmpeg profile. Options are:
+  - `Hardware If Possible` - default/existing behavior when hardware acceleration is properly configured
+  - `Software` - force software padding
+    - This can be used to work around buggy GPU driver behavior where padding is green instead of black
+    - This is most often seen with VAAPI acceleration (radeonsi or i965 drivers)
+- Add API endpoint to clean artwork cache folder (on demand)
+  - POST `/api/maintenance/clean_artwork`
+- Add health check to warn about unsupported empty (classic) schedules
+- Add health check to warn about incompatible ffmpeg due to missing filters
+  - This is directly applicable to homebrew `ffmpeg` on MacOS, which is no longer compatible with ErsatzTV
+    - `ffmpeg@7` or `ffmpeg-full` should be used instead
+- Add `Marathon Group By` option `Director`
+  - This groups the *first* director on Movies, Episodes, Music Videos and Other Videos
+  - This is supported in classic schedules and sequential schedules
+- Add FFmpeg Profile options:
+  - `Normalize Audio` (default: true) - normalizes audio streams, or stream copies when disabled
+  - `Normalize Video` (default: true) - normalizes video streams, or stream copies when disabled
+  - `Normalize Colors` (default: true) - normalizes color parameters when enabled
+  - Disabling any of these options may have a significant performance benefit *at the expense of stream stability*
+- Add chapter `title` to filler expression
+  - This can be used to include or exclude chapters with specific (case-insensitive) titles
+  - E.g. `title == 'here'`, `title != 'not here'`, `title like '%here%'`
+- Local movie libraries: load fanart from `backdrop` files (created by Jellyfin)
+
+### Changed
+- Disable automatic artwork database cleanup
+  - This will be re-enabled at some point in the future (after more testing)
+  - For now, the API should be used to clean as needed
+- Classic Schedules: make multiple `count` an expression
+  - The following parameters can be used:
+    - `count`: the total number of items in the collection
+    - `random`: a random number between zero and (count - 1)
+  - For example:
+    - `count / 2` will play half of the items in the collection
+    - `random % 4 + 1` will play between 1 and 4 items
+    - `2` (similar to before this change) will play exactly two items
+
+### Fixed
+- Use code signing on all Windows executables (`ErsatzTV-Windows.exe`, `ErsatzTV.exe`, `ErsatzTV.Scanner.exe`)
+- Graphics engine:
+  - Respect `z_index` (draw order) on all graphics element types
+  - Fix bug with `z_index` sorting
+- Restore default UI font that was erroneously removed in v26.1.1
+- Classic schedules: fix building playouts when `Fill With Group Mode` schedule items also have graphics elements
+- Use configured searching log level on startup, instead of the default log level of `Information`
+- MySql: fix searching for shows and seasons in schedule items editor
+- Fix 500 errors when serving XMLTV due to concurrent file reads and writes
+- Fix playback of AC3 audio when targeting stereo output and input layout changes mid-stream
+- Use other video artwork in XMLTV template
+- Properly update (add or remove) artwork for all local media libraries when files have changed
+- Sync Plex library name changes
+- Sync Plex episode title, plot, year, date added, release date, episode number changes
+- Sync Jellyfin and Emby library name and type changes
+  - Library type (movies, shows) can only be changed when synchronization is *disabled* for the library in ETV
+- Fix some sequential and scripted playout build failures when using playlists or marathons
+- Fix erasing playout items and history so all related data is also erased
+  - This includes rerun history, unscheduled gaps, build status
+- Fix indexing collections when using Elasticsearch backend
+
+## [26.1.1] - 2026-01-08
+### Fixed
+- Use code signing on Windows launcher (`ErsatzTV-Windows.exe`) to avoid antivirus false positive
+
+### Changed
+- Optimize database check for orphaned artwork
+- Include web resources (CSS, JS) locally instead of relying on CDNs
+
+## [26.1.0] - 2026-01-06
+### Added
+- Graphics Engine:
+  - Add `script` graphics element type
+    - Supported in playback troubleshooting and all scheduling types
+    - Supports arbitrary scripts or executables that output graphics to ETV via stdout
+    - Supports EPG and Media Item replacement in entire template
+      - EPG data is sourced from XMLTV for the current time
+        - EPG data can also load a configurable number of subsequent (up next) entries
+      - Media Item data is sourced from the currently playing media item
+    - All template data will also be passed as JSON to the stdin stream of the command
+    - Template supports:
+      - Script and arguments (`command` and `args`)
+      - Draw order (`z_index`)
+      - Timing (`start_seconds` and `duration_seconds`)
+      - Data format (`format`)
+        - `raw` format means full frames of BGRA data to stdout
+        - `packet` format means ETV graphics packets to stdout
+  - Add framerate template data
+    - `RFrameRate` - the real content framerate (or channel normalized framerate) as reported by ffmpeg, e.g. `30000/1001`
+    - `FrameRate` - the decimal representation of `RFrameRate`, e.g. `29.97002997`
+  - Add `Channel_StartTime` template data
+    - This indicates the time that the transcode session started for the current channel
+- Add remote stream metadata
+  - Remote stream definitions (yaml files) can now contain `title`, `plot`, `year` and `content_rating` fields
+  - Remote streams can now have thumbnails (same name as yaml file but with image extension)
+  - This metadata will be used in generated XMLTV entries, using a template that can be customized like other media kinds
+- Add `Download Media Sample` button to playback troubleshooting
+  - This button will extract up to 30 seconds of the media item and zip it
+- Add `Target Loudness` (LUFS/LKFS) to ffmpeg profile when loudness normalization is enabled
+  - Default value is `-16`; some sources normalize to a quieter value, e.g. `-24`
+- Add environment variables to help troubleshoot performance
+  - `ETV_SLOW_DB_MS` - milliseconds threshold for logging slow database queries (at DEBUG level)
+    - e.g. if this is set to `1000`, queries taking longer than 1 second will be logged
+  - `ETV_SLOW_API_MS` - milliseconds threshold for logging slow API calls (at DEBUG level)
+    - This is currently limited to *Jellyfin*
+  - `ETV_JF_PAGE_SIZE` - page size for library scan API calls to Jellyfin; default value is 10
+  - `ETV_JF_ENABLE_STATS` - enables logging timing information related to Jellyfin show library scans
+- Add `Select All` button to media pages by @Erotemic
+
+### Fixed
+- Fix startup on systems unsupported by NvEncSharp
+- Fix detection of Plex Other Video libraries using `Plex Personal Media` agent
+  - If the library is already detected as a Movies library in ETV, synchronization must be disabled for the library to change it to an Other Videos library
+  - A warning will be logged when this scenario is detected
+- Graphics Engine:
+  - Optimize graphics engine to generate element frames in parallel and to eliminate redundant frame copies
+  - Match graphics engine framerate with source content (or channel normalized) framerate
+  - Fix loading requested number of epg entries for motion graphics elements
+- Fix bug with mirror channels where seemingly random content would be played every ~40 seconds
+- Fix chronological sorting for Other Videos that have release date metadata
+- Fix playout sorting after using channel number editor
+- VAAPI: Only include `-sei a53_cc` flags when misc packed headers are supported by the encoder
+  - This should fix playback in some cases, e.g. AMD VAAPI h264 encoder
+- AMD VAAPI:
+  - work around buggy ffmpeg behavior where hevc_vaapi encoder with RadeonSI driver incorrectly outputs height of 1088 instead of 1080
+  - fix green padding when encoding h264 using main profile
+- Automatically kill playback troubleshooting ffmpeg process if it hasn't completed after two minutes
+- Fix playback of certain BT.2020 content
+- Use playlist item count when using a playlist as filler (instead of a fixed count of 1 for each playlist item)
+- NVIDIA:
+  - Fix stream failure with certain content that should decode in hardware but falls back to software
+  - Fix stream failure with content that changes color metadata mid-stream
+- Fix stream failure when configured fallback filler collection is empty
+- Fix high CPU when errors are displayed; errors will now work ahead before throttling to realtime, similar to primary content
+- Fix startup error caused by duplicate smart collection names (and no longer allow duplicate smart collection names)
+- Fix erroneous downgrade health check failure with some installations that use MariaDB
+- Sequential schedules: fix `count` instruction validation to accept integer (constant) or string (expression)
+- Fix multi-part episode grouping logic so that it does NOT require release date metadata for episodes within a single show
+  - When **Treat Collections As Shows** is enabled (i.e. for crossover episodes) release date metadata is required for proper grouping
+- Fix *many* cases of duplicate names; enforce case-insensitive unique names at the db schema level
+- Fix playback when using `ETV_BASE_URL` by @JamesDearlove
+
+### Changed
+- No longer round framerate to nearest integer when normalizing framerate
+- Allow playlists to have no items included in EPG
+- Change how fallback filler works
+  - Items will no longer loop; instead, a sequence of random items will be selected from the collection
+  - Items may still be cut as needed
+  - Hardware acceleration will now be used
+  - Items can "work ahead" (transcode faster than realtime) when less than 3 minutes in duration
+- Optimize Jellyfin database fields and indexes
+- Optimize Jellyfin show library scans by only requesting `People` (actors, directors, writers) when etags don't match
+  - This should significantly speed up periodic library scans, particularly against Jellyfin 10.11.x
+- Lazy load media item images in UI
+- Align alternate schedule and template handling (between classic schedules and block schedules)
+  - Both systems now support limiting to a date range
+  - This date range can be repeating (when year is not specified for start or end dates)
+  - This date range can be exact (when year is specified for start and end dates)

+# ErsatzTV Fork
+
+Custom IPTV channel server for Jellyfin. Forked from [ErsatzTV/ErsatzTV](https://github.com/ErsatzTV/ErsatzTV) after upstream archival (Feb 2026, v26.3.0). Our fork lives on [Gitea](http://192.168.1.95:3000/timothy/ersatztv).
+
+## Architecture
+
+- **Language**: C# / .NET 10, Blazor Server UI (MudBlazor)
+- **Pattern**: CQRS via MediatR — queries/commands in `ErsatzTV.Application/`
+- **Database**: EF Core (SQLite default, MySQL optional) — context in `ErsatzTV.Infrastructure/Data/TvContext.cs`
+- **Media**: FFmpeg via CliWrap, SkiaSharp for logo generation
+- **Functional C#**: Language Ext (Option, Either monads throughout)
+
+### Project Layout
+
+| Project | Role |
+|---------|------|
+| `ErsatzTV/` | ASP.NET Core host, Blazor pages, API controllers, DI setup |
+| `ErsatzTV.Application/` | MediatR handlers (business logic) |
+| `ErsatzTV.Core/` | Domain entities, interfaces, no infrastructure deps |
+| `ErsatzTV.Infrastructure/` | EF Core repos, data access |
+| `ErsatzTV.Infrastructure.Sqlite/` | SQLite-specific implementations |
+| `ErsatzTV.FFmpeg/` | FFmpeg process wrapper |
+| `ErsatzTV.Scanner/` | Media library scanning |
+
+### Key Files
+
+- **M3U generation**: `ErsatzTV.Core/Iptv/ChannelPlaylist.cs` → `ToM3U()`
+- **XMLTV generation**: `ErsatzTV.Application/Channels/Queries/GetChannelGuideHandler.cs`
+- **IPTV controller**: `ErsatzTV/Controllers/IptvController.cs` — `/iptv/*` routes
+- **Logo generation**: `ErsatzTV.Core/Images/ChannelLogoGenerator.cs`
+- **Channel entities**: `ErsatzTV.Core/Domain/Channel.cs`
+- **DB context**: `ErsatzTV.Infrastructure/Data/TvContext.cs`
+
+## Deployment
+
+- **Docker host**: jazz (192.168.1.99), container `ersatztv`, port 8409
+- **Config volume**: `~/downloadswarm/ersatztv/` on jazz → `/config` in container
+- **SQLite DB**: `/config/ersatztv.sqlite3` (WAL mode, root-owned)
+- **Images** (our fork, built by `.gitea/workflows/docker-build.yml` → `192.168.1.95:3000/timothy/ersatztv`): push to `main` → `:latest` + `:<sha>` (test image); push `v*` tag → `:prod` + `:<version>` + `:<sha>`. Prod container still runs upstream `ghcr.io/ersatztv/ersatztv:latest` pending cutover (server-management#481). Pipeline details: `docs/ci-cd.md`.
+
+## Development
+
+```bash
+# Build
+dotnet build ErsatzTV.sln
+
+# Run locally (needs FFmpeg in PATH)
+dotnet run --project ErsatzTV
+
+# Docker build
+docker build -f docker/Dockerfile -t ersatztv:dev .
+```
+
+## Conventions
+
+- **Read [`docs/contributing.md`](docs/contributing.md)** before non-trivial changes — it documents the established patterns (layering, CQRS handlers, LanguageExt, Blazor/MudBlazor, EF Core + dual-provider migrations, the FFmpeg pipeline, analyzers, testing) and the **deviation policy**: match the established style; diverge only with a concrete, stated reason.
+- Follow existing MediatR CQRS pattern for new features
+- Domain logic in `ErsatzTV.Core`, infrastructure in `ErsatzTV.Infrastructure`
+- Keep Blazor pages thin — delegate to MediatR handlers
+- Test with **NUnit** + Shouldly + NSubstitute (the existing `*.Tests` projects); xUnit is **not** used here
+- **Dependencies use Central Package Management**: versions live in the repo-root `Directory.Packages.props`; csproj reference packages by name only. Add/upgrade by editing the central `<PackageVersion>` — never put `Version=` back on a `<PackageReference>` (trips `NU1008`). See `docs/ci-cd.md` → Dependency management.
+- **DB migrations target BOTH providers**: a `TvContext` model change needs a migration in `ErsatzTV.Infrastructure.Sqlite` **and** `ErsatzTV.Infrastructure.MySql` — run `scripts/add-migration.sh <Name>` (does both). CI's `migrations` job enforces model-drift + apply-to-fresh-DB per provider. See `docs/ci-cd.md` → Migration integrity.
+- **Renovate** is live (`.gitea/workflows/renovate.yml`, weekly + `workflow_dispatch`): opens dependency-update + OSV vuln-fix PRs and a Dependency Dashboard issue; patch bumps to test/dev-only packages auto-merge once `Build & test` passes, the rest are manual. Cross-repo rollout: server-management#484. See `docs/ci-cd.md` → Dependency management.
+- **Versioning**: release tags are `vYY.<release-seq>.<patch>` (year · sequential release-within-year · patch) — inherited from upstream, **not** year.month. `v26.3.1` = our infra rebuild of upstream 26.3.0 (no app changes); `v26.4.0` is reserved for the first release with app changes. Never `[skip ci]` a commit you'll tag (it suppresses the release build). Full policy: `docs/ci-cd.md` → Versioning & releases.
+- Backlog tracked via [Gitea Issues](http://192.168.1.95:3000/timothy/ersatztv/issues)
+
+## Task Completion Protocol
+
+Every task that closes a Gitea issue MUST complete ALL of these before it is considered done. Use `/done <issue>` to run through this automatically.
+
+1. **Root cause** (bug fixes / incidents only): Document WHY the problem existed, not just what was changed. If root cause is unknown, say so explicitly and open a follow-up investigation issue. Fixing symptoms without understanding causes creates recurring problems.
+2. **Comment on issues** as you work — what you found, what approach you're taking, any deviations from the suggested fix.
+3. **Push changes**: `git push` all commits before closing. Use `fixes #N` in commit messages to auto-close where appropriate.
+4. **Close comment**: Add a structured closing comment on the issue covering: what was done, root cause (if applicable), files changed, anything deferred, follow-up issues created, and which docs were updated.
+5. **Close the issue** via API or `fixes #N` commit. Leave open with a comment only if partially addressed.
+6. **Update docs**: If the change affects operational behavior, update the relevant Obsidian docs (`~/homelab-docs/`), MEMORY.md, or CLAUDE.md inline — not as a follow-up.
+7. **Reply to reviewer** (if from adversarial review): Summary of done/deferred/questions. This triggers the next review cycle.
+
+## Project Boundaries
+
+**ersatztv OWNS**: ErsatzTV fork code (C#/.NET), channel/collection/schedule management, M3U/XMLTV generation, the ErsatzTV skill in server-management.
+
+**ersatztv does NOT own**:
+- Docker compose configs → server-management (`~/downloadswarm/stacks/ersatztv/`)
+- NFS mounts, Ansible, DNS, networking → server-management
+- Content sourcing (yt-dlp downloads, Sonarr/Radarr libraries) → media-management (planned)
+- Jellyfin skill → server-management (symlinked)
+
+**For infrastructure changes** (Docker, NFS, ports, Authelia): open an issue in `timothy/server-management`.
+
+**For content/media sourcing questions** (what goes into channels, yt-dlp pipelines): open an issue in `timothy/media-management` once it exists; for now, `timothy/server-management`.
+
+**For plan/audit reviews**: open `~/adversarial-reviewer` before significant architecture changes.
+
+**Full cross-project rules**: `~/homelab-docs/Operations/Project Boundaries.md` (https://docs.tblindustries.be).
+**ErsatzTV docs**: `~/homelab-docs/Docker/ErsatzTV.md` + project-local `docs/` (fork strategy, channels, M3U/XMLTV).
