# Data Model Two sets: the **config + state schemas in use today** (the app and helpers read and write these), and the **fleet/mesh data model** (single-fleet core implemented in the governor's fleet engine; cross-fleet parts still design). --- ## In use today ### `devices.json` — device registry + playback target config Path: `~/.config/tv-anarchy/devices.json` (auto-migrated forward from `~/.config/tv-anarchy/hosts.json`, and before that `~/.config/plumtv/hosts.json`). Source: `Sources/TVAnarchyCore/DeviceConfig.swift`. Written pretty-printed + sorted-keys; seeded on first run with Plum VLC + Black (mpv) if absent. The decoder accepts the legacy top-level `hosts` key alongside `devices`. Each device carries a `type` — `cellphone | laptop | storage | seed | broadcast`, mapping to the planned fleet classes `consumer | roamer | server | seedbox | broadcast` — and an overridable `services` preset (`stream`, `offlineCache`, `ttlSeed`, `custody`, `publicSwarmFace`, `f2fRelay`, `meshAnchor`). Legacy entries without a `type` get one inferred from the player backend. ```jsonc { "devices": [ { "id": "plum-vlc", "name": "Plum VLC", "kind": "vlc", // vlc | mpv-ipc | quicktime | blacktv(legacy) "type": "laptop", // cellphone | laptop | storage | seed | broadcast "services": { "stream": true, "offlineCache": true, "ttlSeed": true }, "vlc": { "host": "127.0.0.1", "port": 8080 } }, { "id": "black", "name": "Black TV", "kind": "mpv-ipc", "type": "storage", "services": { "stream": true, "custody": true }, "mpv": { "endpoints": ["lilith@10.0.0.11", "lilith@10.9.0.4"], // LAN first, WG overlay fallback "socket": "/tmp/mpv.sock", // default "sudo": true, // root-owned socket → sudo socat "socat": "socat", // default "volumeScale": 130 // mpv --volume-max }, "commands": { // argv templates for what IPC can't do "launchShow": ["/usr/local/bin/black-tv","play-show","{query}","{season?}","{episode?}"], "launchResume": ["/usr/local/bin/black-tv","resume-show","{query}"], "launchFile": ["/usr/local/bin/black-tv","play","{path}"], "releases": ["/usr/local/bin/black-tv","releases"], "resolveRelease": ["/usr/local/bin/black-tv","resolve-release","{releaseId}"], "stats": ["/usr/local/bin/black-tv","stats"], "stop": ["/usr/local/bin/black-tv","stop"], "restart": ["/usr/local/bin/black-tv","restart"] } } ] } ``` Notes: - `kind`: `vlc`, `mpv-ipc`, `quicktime`. `blacktv` is legacy and auto-migrated to `mpv-ipc` at load; only `mpv-ipc`/`vlc`/`quicktime` are offered in the editor. - Command-template tokens: `{query}`, `{season?}`, `{episode?}`, `{path}`, `{releaseId}` (a `nil` template = capability absent). - VLC password is **not** stored here — it's resolved at runtime from the governor's config or `$VLC_HTTP_PASSWORD` (see `VLCConfig`). - `MpvConn` decodes from a minimal `{ "endpoints": [...] }`; every other field has a default. ### `config.json` — governor (`portable-net-tv`) Path: `~/.config/portable-net-tv/config.json` (source: `governor/README.md`). ```jsonc { "vlcHttp": { "host": "127.0.0.1", "port": 8080, "password": "" }, "buffer": { "dir": "/Users/natalie/Movies/net-tv-buffer", "ahead": 3, "minFreeGB": 2 } } ``` `buffer` is optional (defaults: `~/Movies/net-tv-buffer`, `ahead` 3, `minFreeGB` 2). ### Watch log — append-only JSONL (the watch protocol) Primary path: `~/.local/state/tv-anarchy/watched.jsonl` (plum-side; the app, governor, and mcp all append here). Legacy path `~/.local/state/tv-anarchy-mcp/watched.jsonl` is auto-migrated on first read (`packages/media`). Black TV plays are mirrored from black's `~/.local/state/black-tv/watched.jsonl` into a local `black-watched.jsonl` cache (by `BlackWatchlog` + `WatchHistoryController.syncBlack`); both files are unioned at read time. One JSONL event per line (full shape and finish rule in [architecture.md](./architecture.md#playback-observation-finish-detection-and-the-watch-log-protocol)): ```jsonc { "ts": "...", "event": "play|resume|reset", "show": "…", "season": 1, "episode": 3, "label": "…", "path": "/bigdisk/_/media/.../Show S01E03.mkv", "resumeSeconds": 1234, "durationSeconds": 2400, "client": "app|governor|bridge|black", "finished": true } ``` - `"play"` events (or `resumeSeconds >= durationSeconds * 0.92`) advance the Continue Watching frontier and `playedPaths`. - `"resume"` events supply live positions for bars and mid-episode resume targets. - `"reset"` clears played state for a rewatch (history is preserved). - `client` ("app", "governor", "bridge", "black", "mcp", ...) tags provenance. `FINISHED_FRACTION = 0.92` is the single threshold (enforced on write in a few places, on read in `isWatchFinished` helpers). - Readers in the app (`WatchHistory`, `LibraryController.resumeTarget` etc.), governor, and mcp bridge all derive Continue / resume / badges exclusively from this log. No other source of truth. (The obsolete direct "VLC recents" macOS plist integration has been removed.) ### App-local cache + state | Artifact | Path | Writer | |---|---|---| | App settings | `~/.local/state/tv-anarchy/settings.json` | `SettingsStore` (adult gating, hover previews, media-key forwarding, offline-cache sizing; tolerant decode) | | Library snapshot | `~/.local/state/tv-anarchy/library.json` | `LibraryStore` | | Metadata sidecar | `~/.local/state/tv-anarchy/meta/.json` | `MetaWriter` (mirrored best-effort to `.meta` on black) | | Artwork cache | frame-grab JPEGs (keyed by path) | `ArtworkService` | | watched.jsonl (watch log) | `~/.local/state/tv-anarchy/watched.jsonl` (+ black mirror) | app, governor, bridge, black mpv Lua (see architecture.md) | ### Library models (in-memory / snapshot) `CachedShow { name, rootDir, category, kind(series|movie), posterPath, overview, episodes[], year, seasonCount, episodeCount, addedAt }`, `CachedEpisode { path, season, episode, label, metaPath }`, `LibrarySnapshot { shows[], capturedAt, source(scan|registry) }`, `ContinueItem { title, path, show, season, episode, positionSeconds, lastSeen, source(watchlog|vlc), posterPath }`. Decoders are tolerant so old snapshots load. `ParsedFilename { title, year, season, episode, quality, codec, releaseSource }`, `MediaMeta { path, parsed, resolvedTitle, mediaType, overview, posterURL, ratings, genres, enrichedAt }`. --- ### `fleet.json` — the fleet registry (app-side) + governor policy Path: `~/.config/tv-anarchy/fleet.json`. The `devices` **array** is the app-side fleet registry (authoritative for the governor's fleet engine when present; `devices.json` is the fallback): ```jsonc { "devices": [ { "id": "black", "name": "black", "deviceClass": "server", // server|roamer|consumer|seedbox|broadcast "alwaysOn": true, "onHomeIp": true, "reachable": "home_lan", "duties": ["custody_floor"], // app-side record; the governor recomputes "services": [ { "id": "black", "kind": "mpv-ipc", "detail": "lilith@10.0.0.11" }, { "id": "black-transmission", "kind": "transmission", "detail": "transmission RPC" } ] } ], // Optional governor policy keys (read by governor/src/fleet/registry.ts): "floorCopies": 2, // custody floor (default 2) "sources": [ // peer sources; gates enforced on load { "id": "dht", "kind": "dht" } // implicit when absent ], "staticHoldings": { "apricot": ["Show Name S01"] } // copies on api-less hosts } ``` The governor derives from this: `api` (a `transmission` service → `transmission_rpc`), `ssh`/`addr` (a `user@host` service detail), and capacity defaults. Engine state (last duty assignment, for change diffs) lives at `~/.local/state/tv-anarchy/fleet-state.json`. Title-refiner cache: `~/.local/state/tv-anarchy/title-refinements.json` (filename → refined title, empties cached too). --- ## Fleet/mesh data model (single-fleet core implemented) Synthesized from [`../.project/history/20260608_fleet-manager-mesh-design.md`](../.project/history/20260608_fleet-manager-mesh-design.md). The single-fleet subset — host registry, duty rules, custody floor, reaper, source gates, `peers_for`/`custodians_of` — is implemented in `governor/src/fleet/` (types in `types.ts` mirror the entities below). Identity/Fleet entities and everything cross-fleet remain design. ### Entities ``` Identity { discord_id, display_name, fleets[] } Fleet { id, identity, hosts[], sources[], custody_capacity } Host { ...registry, below... } Source { ...peer-source, below... } ``` `custody_capacity = Σ over always_on hosts of (disk_free × uptime_score)` — whether a fleet can hold a floor or is a net consumer. Gift-economy mode ignores it for prioritization; ratio mode (off by default) weights by it. ### Host registry ``` Host { id, fleet_id class: server | roamer | consumer | seedbox | broadcast // what it IS reachable: home_lan | wireguard | public_ip always_on: bool on_home_ip: bool // true = public-swarm traffic exposes the home connection api: transmission_rpc | qbittorrent | utorrent_web | none capacity: { disk_free, up_bw, uptime_score(∈[0,1], rolling) } duties: Duty[] // assigned by the manager, never hardcoded — what it DOES } Duty = custody_floor | public_swarm_face | f2f_relay | broadcast ``` Example fleet: black = server, apricot = secondary always-on, plum = roamer (TTL seeder), phone = consumer (pure sink, never any duty). > **Partially landed:** the app's `devices.json` (above) already carries the > class mapping (`DeviceType.fleetClass`) and a `services` preset that mirrors > the duty vocabulary. What does **not** exist is the manager that *assigns* > duties from capacity/reachability — services today are user-set presets, not > computed duties. ### Duty-assignment rules (deterministic, run on registry change) | Duty | Eligibility | Rule | |---|---|---| | `broadcast` | `public_ip && always_on` | exactly ONE per fleet; prefer seedbox > vps-0 > server | | `f2f_relay` | `always_on && reachable ∈ {wireguard, public_ip}` | broadcast host + any other always-on server | | `public_swarm_face` | prefer `!on_home_ip` | seedbox FIRST; never a consumer; never on_home_ip if an off-home option exists | | `custody_floor` | `always_on && disk_free > title_size` | N most-recent eligible holders; ≥1 slot reserved for an always-on node | Invariants: a `consumer` never receives a duty (checked first); `public_swarm_face` prefers off-home-IP so home stays dark; every active title's floor keeps ≥1 always-on holder. ### Peer-source model ``` Source { id, fleet_id kind: dht | public_tracker | private_tracker | friend_mesh | fleet_host | seedbox api/creds: share_policy: search_only | content // private_tracker DEFAULT-CLOSED (search_only) swarm_isolation: f2f_only | open // private_tracker FORCED to f2f_only (un-overridable) } ``` Two policy gates are load-bearing because a private `.torrent` carries an embedded passkey — a friend announcing it to the private tracker gets the **source** user banned: 1. `share_policy` gates the registry merge; flipping private → `content` triggers a consequence-explicit warning naming the tracker. 2. `swarm_isolation = f2f_only` is forced for private sources: content is re-hosted into the fleet's own WireGuard swarm, served `via: wireguard`, never announced to the private tracker. Seedbox sources are `content` + `open` (no gates). ### Derived outputs (the point of everything above) ``` peers_for(infohash) → Peer[] // holistic seeder list / user-owned meta-tracker custodians_of(title) → Host[] // who is obligated to keep it alive Peer { addr, source_kind, source_id, served_via: public | wireguard } ``` `peers_for` unions privates ∪ fleet ∪ friends' fleets ∪ seedbox ∪ DHT/public, provenance-tagged so the UI can show *why* a peer exists and over what transport.
