Transcode ladder rungs (328p, 720p-high, 1080p-8 and friends) are deliberately absent — they were never a third dimension, only a bitrate spelled into the resolution string. web/src/player/hooks/useTranscodeQuality.ts already decomposes them, defining 1080p-high as {resolution: 1080p, bitrate: 10000} and sending the two to the server separately, so the compound form never reached the wire. playback.max_bitrate_kbps is now that second axis, and clients compose the two into whatever presets they want to show. Members are listed ascending so the ceiling constraint has a defined direction; \"auto\" sorts lowest because it never exceeds a cap, and \"original\" highest because it is the uncapped source.

Two values rather than one compound enum means a client can offer \"1080p High\" without the server having to agree on what \"High\" means — retuning a preset is a client release, not a contract break, and it stays additive under the widening rule. null is uncapped, which is why this is nullable rather than defaulting to a large number: absent and \"as much as you like\" are the same statement, and a numeric sentinel would have to be widened every time hardware improves. The bounds are deliberately loose — 100 kbps is below any watchable stream and 200 Mbps is above any remux — because this caps a preference, not a policy; entitlement limits live in internal/policy.

A client PR must not +invent a production setting key, type, default, range, or scope independently. + +There is one narrow exception: a client may add a private implementation, diagnostics, or +experimental knob without a server PR when all of the following are true: + +1. Its key is in `local...` (for example, + `local.apple.player.decoder_logging`). +2. It is not shown as a normal production setting. +3. It is never sent to any Silo API. +4. It is not expected to roam, survive reinstall, appear in admin UI, or have shared semantics with + another client. +5. Promoting it to a production feature requires adding it to the shared contract first. + +This gives clients freedom for genuine local implementation details without allowing the public +settings model to drift again. + +The contract lands as **one coordinated breaking release**: the manifest, typed API, canonical +storage, migration, and removal of the legacy settings surface ship together, and server, bundled +web, Apple, and Android update at the same time. Mixed-version operation is not supported. + +That is a deliberate choice against a phased rollout. Phasing would mean building a compatibility +projection of the old API over the new resolver, plus bindings from the manifest to the tables the +migration is about to replace — both written only to be deleted, in a subsystem where the +transitional code would be a meaningful fraction of the permanent code. The project is pre-1.0, +`docs/architecture/v1-scope.md` is not locked, and the data volumes are small. One clean switchover +costs less than the scaffolding needed to avoid it. + +**After this release, no future setting requires coordination.** The release is the only lockstep +event in this design; everything after it is governed by manifest revisions, which move +independently per repository.

It must not copy ordinary-browser device overrides. The +incognito window gets a new device identity and resolves those settings from the profile fallback. + +The UI must use these exact scope descriptions: + +- **All devices for this profile** — profile value that roams after sign-in. +- **This device, for this profile** — override tied to the active profile *and* device identity. +- **Only this app/device** — client-local value that is never uploaded. +- **Everyone on this account** — account-scope value shared by every profile. + +Avoid ambiguous labels such as “global,” “default,” or “remember this” without naming what the +value follows. + +The device label names both halves of the identity deliberately. A bare “This device/browser” +implies the value applies to whoever is using the device, which is exactly backwards on the shared +screens where device overrides matter most: a living-room TV used by four household profiles. A +user who reads “This device” on a family TV will reasonably assume they are changing it for the +household, and the actual behavior — a private override for their profile alone — is the opposite. + +## Why this is needed + +The current implementation has three partial contracts: + +- `silo-server: internal/api/handlers/settings.go` owns validation, defaults, and a `user` versus + `device` registry, but unknown user keys are accepted and values are strings. +- `silo-server: web/src/lib/settingsManifest.ts` independently owns labels, controls, defaults, + enum options, and numeric ranges. It registers no user-scope keys at all and omits several + registered device keys, so the duplication is structurally incomplete, not just drift-prone. +- Apple and Android independently own raw key constants, defaults, parsing, and local migration + behavior. + +That duplication has produced verified drift: + +- Apple writes `playback.audio_language`, but playback selection reads the profile language; the + device value currently has no effect. +- Android uses `player.next_up_prompt_seconds` while the server and Apple use + `playback.next_up_prompt_seconds`. +- Android permits playback speed up to `4.0`; the server contract permits `3.0`. +- Android defaults `player.dv_profile7_hdr10_fallback` to `true`; the server and Apple default it to + `false`. +- Android contains device-setting keys the server does not register. +- Apple queues failed writes only in memory and keys them only by setting key, so process death + loses pending work and a profile/server switch can redirect a retry. +- Android removes pending writes before the server accepts them and only logs failures. +- Profile columns and device settings represent some of the same user intent but use separate API + and resolution paths. +- jellycompat's Jellyfin `DisplayPreferences` handler seeds its first-run state from the profile + subtitle and auto-skip columns and persists its blobs through the legacy string settings store + under `jellycompat:displayprefs:*` keys, coupling third-party client state to both surfaces this + design retires. + +There is also a fourth contract that #376 did not cover, and it is the one most likely to be +overlooked: **`internal/policy` already resolves restrictions over the same subject matter.** +`internal/policy/input.go` carries `account_max_playback_quality`, `profile_max_playback_quality`, +and `profile_preferred_metadata_language`, and `user_profiles` carries `max_playback_quality`, +`max_content_rating`, and `library_restrictions_enabled` alongside the preference columns +`quality_preference` and `preferred_metadata_language`. A settings contract that resolves +preferences without consulting that engine produces a second, disagreeing answer for the same +user-visible control. See **Preferences versus restrictions**. + +The web client also has useful precedent to preserve: owner-tagged cached date/time settings avoid +showing one account's cached values to another account. Theme and custom-style caches need the same +ownership rule. + +### Verified baseline + +This design was checked against these repository heads: + +| Repository | Commit | +|---|---| +| `silo-server` | `3fd0912cb3fe15cc364f3dd04095c2e39db0bef0` | +| `silo-apple` | `120f493593119e71dfb1247dde0f89c55d46c1d0` | +| `silo-android` | `5c6439cebe753103c3a12cca7d1d152c5d6e35ab` | + +The `silo-apple` commit sits on `feature/tvos-manual-up-next`, not `main`; its merge base with +`main` is `169e4917`.

Settings express what a user wants; policy expresses what the + account, profile, and access groups permit. Policy stays authoritative. + +## Terminology + +- **Definition** — the canonical key, type, constraints, scopes, defaults, resolution, and UX + metadata for one setting. +- **Stored value** — an explicit value at one allowed scope. +- **Unset** — no explicit value at that scope. This is distinct from `false`, `0`, `""`, and + JSON `null`. +- **Effective value** — the first stored value found in the definition's resolution order, or the + contract default. +- **Override** — a more specific stored value that wins over a broader fallback. +- **Contract-known local** — a production user-facing setting defined by the shared contract but + persisted only by the client. +- **Private local** — a non-production implementation or diagnostics knob outside the shared + contract. +- **Restriction** — an enforced ceiling or lock owned by `internal/policy` (parental controls, + access groups, account/profile `max_playback_quality`). A restriction is not a setting and is + never stored in this contract; it constrains what an effective value is allowed to be. +- **Permitted value** — the effective value after policy constraint. Clients render and act on the + permitted value, never on the raw effective value. + +## Ownership classes + +Every setting definition declares one persistence class: + +| Persistence | Contract PR required | Server stores value | Sent to API | Intended use | +|---|---:|---:|---:|---| +| `remote` | Yes | Yes | Yes | Roaming values and server-known device/profile overrides | +| `client_local` | Yes | No | No | Production OS/device behavior with shared, reviewed semantics | +| Private `local.*` | No | No | No | Diagnostics, implementation details, temporary experiments | + +A setting that is visible in the production Settings UI is contract-owned. A setting implemented +by two or more clients is contract-owned. A setting expected to survive sign-in on a new client is +`remote`. + +## Canonical contract artifact + +The source of truth lives in `silo-server`: + +```text +contracts/settings/v1/ +├── manifest.schema.json +├── manifest.json +└── schemas/ + └── subtitle-appearance.json +``` + +- `manifest.schema.json` validates the contract format. +- `manifest.json` contains definitions and is embedded by the server. +- Object-valued settings use a named JSON Schema under `schemas/`. +- Server tests load the manifest and fail on duplicate keys, invalid defaults, invalid resolution + chains, or missing schemas. +- `GET /api/v1/settings/manifest` serves this exact public artifact, excluding internal storage + bindings. +- The canonical JSON bytes are the RFC 8785 (JCS) canonicalization of the manifest: UTF-8, + lexicographically sorted object keys, no insignificant whitespace. `ETag` is the SHA-256 digest + of those bytes, and generated-code reproducibility is defined over the same bytes. + +The API version and contract revision are separate: + +```json +{ + "api_version": 1, + "revision": 12, + "definitions": [] +} +``` + +- `api_version` identifies the settings protocol. It changes only for a change no revision rule + below can express. +- `revision` is a monotonically increasing integer changed by every manifest PR. + +Within one `api_version`, revisions are monotone-compatible in both directions. A client pinned to +an older revision remains valid; a client pinned to a newer revision hides what the connected +server does not know. That property depends on classifying every manifest change: + +| Change | Allowed within `api_version` | Requires | +|---|---|---| +| Add a key | Yes | Revision bump | +| **Widen** `allowed_scopes` (add a more specific override scope) | Yes | Revision bump; new scope carries `introduced_in` | +| Add an enum member | Yes | Revision bump; member carries `introduced_in` | +| Widen a numeric range | Yes | Revision bump; bound carries `introduced_in` | +| Change a default | Yes | Revision bump plus explicit release notes — behavior changes with no stored value changing | +| Deprecate a key | Yes | Revision bump; `deprecated: true`, definition stays published | +| **Narrow** `allowed_scopes`, tighten a range, remove an enum member | No | New key, plus a migration for every previously valid stored value | +| Change value type, persistence class, or meaning | No | New key | + +Widening is safe in a way narrowing is not, and the two must not share one rule. An older client +that does not know a newly added scope still receives a correctly resolved value and can read +`source`; it simply cannot author at that scope. An older client that has already stored a value +at a scope you remove has nowhere to put it. + +Because defaults, enum members, ranges, and scopes can therefore all move within one +`api_version`, revision awareness has to be finer than whole definitions: + +- `introduced_in` is a **manifest revision**, not an `api_version`. +- Every additively introduced sub-element — an enum member, a scope, a widened bound — carries its + own `introduced_in`. +- A client filters options, scopes, and bounds against the server's advertised revision before + rendering or sending them. This is what prevents a newer client from offering a choice an older + server will reject with `invalid_value` for reasons the user cannot act on. + +Published definitions are never unpublished. A deprecated definition stays in the manifest with +`deprecated: true` so older clients continue to resolve it. + +## Definition model + +The public definition is a tagged, typed record: + +```json +{ + "key": "playback.audio_language", + "introduced_in": 1, + "persistence": "remote", + "allowed_scopes": ["profile", "profile_device", "profile_library", "profile_series"], + "resolution_order": ["profile_series", "profile_library", "profile_device", "profile", "default"], + "value_schema": { + "type": "language_tag", + "nullable": true + }, + "default_value": null, + "platforms": ["web", "ios", "tvos", "macos", "android", "android_tv"], + "category": "playback", + "label": "Preferred audio language", + "description": "Choose which spoken language Silo should prefer first.", + "deprecated": false +} +``` + +A definition that policy can constrain declares that binding explicitly, and additively introduced +sub-elements carry their own revision: + +```json +{ + "key": "playback.preferred_quality", + "introduced_in": 1, + "persistence": "remote", + "allowed_scopes": ["profile", "profile_device"], + "resolution_order": ["profile_device", "profile", "default"], + "value_schema": { + "type": "enum", + "values": [ + { "value": "auto" }, + { "value": "1080p" }, + { "value": "2160p" }, + { "value": "1080p-high", "introduced_in": 14 } + ], + "ordered": true + }, + "default_value": "auto", + "constrained_by": { + "policy_input": "max_playback_quality", + "constraint": "ceiling" + }, + "category": "playback", + "label": "Preferred quality", + "description": "Pick the quality Silo should prefer.", + "deprecated": false +} +``` + +Required fields: + +| Field | Rule | +|---|---| +| `key` | Lowercase dot-separated identifier. Canonical names do not encode a platform. | +| `introduced_in` | Manifest revision that first published this definition. | +| `persistence` | `remote` or `client_local`. | +| `allowed_scopes` | Non-empty and valid for the persistence class. Individual scopes added after `introduced_in` carry their own `introduced_in`. | +| `resolution_order` | Contains every remote scope at most once and ends in `default`. | +| `value_schema` | One tagged schema from the type system below. | +| `default_value` | Valid against `value_schema`; may be JSON `null` only when nullable. | +| `category` | Stable grouping for docs/admin UX; not authorization. | +| `label`, `description` | Canonical English copy. Clients may localize it. | + +Optional fields include `unit`, `recommended_control`, `platforms`, `constrained_by`, and localized +option identifiers. + +`platforms` is **advisory UI metadata only**. It tells a client whether a setting is expected to be +meaningful on that platform so unsupported entries can be hidden rather than shown disabled. The +server does not enforce it, because enforcement would mean every new platform, form factor, or +client needs a manifest PR before it can write a setting it already implements correctly. Omitting +`platforms` means "expected everywhere." + +Validation, scope, resolution, defaults, and `constrained_by` are normative. Everything else is +advisory. + +Internal server bindings map a definition to existing profile columns or preference stores. They +must not expose table or column names in the public manifest. + +## Value type system + +The v1 contract supports these tagged schemas: + +| Type | Constraints | JSON value | +|---|---|---| +| `boolean` | none | `true` | +| `integer` | `minimum`, `maximum`, optional `step` | `30` | +| `number` | finite `minimum`, `maximum`, optional `step` | `1.25` | +| `string` | `min_length`, `max_length`, optional `pattern` | `"fit"` | +| `enum` | non-empty `values` array of member objects; optional `ordered` | `"always"` | +| `language_tag` | well-formed BCP 47 tag; optional null | `"en-US"` | +| `object` | required `schema_ref` | `{ "fontScale": 1.2 }` | + +Rules: + +- New APIs transport native JSON values. Booleans and numbers are not quoted. +- `NaN`, infinities, duplicate object keys, and values outside declared constraints are rejected. +- `unset` is an operation, not a value. JSON `null` is allowed only when the definition says it is + meaningful. +- Enum wire values are stable identifiers, never localized labels. +- An enum member is an object — `{ "value": "always", "introduced_in": 14 }` — not a bare string, + so members added after the definition can carry their own revision. `introduced_in` is omitted + when the member shipped with the definition. +- `ordered: true` declares that members form a meaningful progression (quality ladders, size + steps). A `ceiling` or `floor` policy constraint is only valid on an ordered enum or a numeric + type, since otherwise "cap this value" has no meaning. +- Language values are normalized to a canonical BCP 47 representation while preserving valid + region/script specificity. +- Arbitrary untyped JSON is not allowed. Existing `subtitle_appearance` becomes an `object` with a + versioned schema. + +## Scopes and identity + +The remote scopes are: + +| Scope | Identity tuple | Meaning | +|---|---|---| +| `account` | `(user_id)` | Same for every profile and signed-in client on the account. | +| `profile` | `(user_id, profile_id)` | Roams with one profile. | +| `profile_device` | `(user_id, profile_id, device_id)` | Override for one profile on one device identity. | +| `profile_library` | `(user_id, profile_id, library_id)` | Content preference for one library. | +| `profile_series` | `(user_id, profile_id, series_id)` | Content preference for one series. | + +`client_local` definitions use a single logical `client_local` scope and are never addressed by the +server values API. + +All remote mutations carry their complete identity explicitly. The server authorizes that the +profile, library, series, and device belong to the authenticated user. A queued operation must not +derive its profile or server from whichever account happens to be active when the retry runs. + +Device identity remains an installation/browser identity, not a person identity: + +- A normal browser profile persists one random device ID. +- An incognito/private window receives a different, ephemeral device ID. +- Clients must not fingerprint hardware to reconstruct a deleted device ID. +- Merely reading effective settings may update `last_seen_at`, but empty device records with no + settings, downloads, push registration, or other durable relationship are removed after 90 days. +- Users and admins can explicitly **Forget device**, which removes its settings and registrations + through the existing device cleanup path. + +## Resolution + +There is no universal hard-coded precedence. Each definition declares its resolution order and the +server is the only canonical resolver. + +Examples: + +| Setting family | Resolution order | +|---|---| +| Audio/subtitle selection | series → library → device → profile → default | +| Playback behavior with device override | device → profile → default | +| Device playback capability | device → default | +| Account UI preference | account → default | +| Client-local OS behavior | local value → default | + +Clients may cache effective values but must not reimplement a different precedence. Playback and +catalog code consume the server resolver or a server-produced effective preference snapshot. + +The effective response identifies value, source, and any policy constraint: + +```json +{ + "key": "playback.audio_language", + "value": "ja", + "source": "profile_library", + "source_context": { "profile_id": "p1", "library_id": "42" }, + "definition_revision": 12, + "updated_at": "2026-07-10T15:03:04Z" +} +``` + +## Preferences versus restrictions + +Silo already has a second resolver. `internal/policy` evaluates access groups, parental controls, +and the account/profile `max_playback_quality` ceiling, and it is authoritative for what a viewer +is permitted to do. This contract must not become a competing answer to the same question. + +The seam is: + +- **Settings answer "what does this user want?"** They are authored by the user and stored here. +- **Policy answers "what is this user allowed to have?"** It is authored by an admin or a household + parent, evaluated by `internal/policy`, and never stored in `user_setting_values`. + +Without an explicit seam the failure is concrete and immediate: a child profile capped by +`max_playback_quality` at `720p` opens the quality picker, the settings resolver reports an +effective value of `2160p`, the client renders 4K as selected and selectable, the user picks it, +and playback silently delivers something else. The same shape applies to +`catalog.metadata_language` against `profile_preferred_metadata_language` and to any future +restriction. + +Therefore: + +1. A definition that policy can constrain declares `constrained_by` with the policy input it reads + and the constraint kind (`ceiling`, `floor`, `allowlist`, or `locked`). +2. The effective-values endpoint applies the constraint and reports both values: + +```json +{ + "key": "playback.preferred_quality", + "value": "720p", + "requested_value": "2160p", + "source": "profile_device", + "constrained_by": { "policy_input": "max_playback_quality", "constraint": "ceiling" }, + "permitted_values": ["auto", "480p", "720p"], + "definition_revision": 12, + "updated_at": "2026-07-10T15:03:04Z" +} +``` + +3. `value` is the permitted value. Clients act on it. `requested_value` appears only when a + constraint changed the outcome, so the UI can explain the difference instead of silently + disagreeing with the user's stored choice. +4. `permitted_values` narrows the manifest's declared options for this viewer. Clients render from + `permitted_values` when present, and from the manifest otherwise. +5. Mutations are **not** rejected for exceeding a restriction. Storing a preference the current + policy forbids is legitimate: restrictions change, and a child's stored 4K preference should + take effect on the day the cap is lifted rather than being destroyed by it. Validation rejects + values invalid against the *definition*; policy constrains at resolution time. +6. Playback and catalog paths consume the permitted value. They must not re-resolve the raw stored + value and re-apply policy independently. +7. A `locked` constraint means the user cannot author the setting at all under current policy. UI + shows the value with a lock affordance and an explanation, not a disabled control with no reason. + +Rule 5 is the one that is easy to get backwards. A restriction is a filter on what a preference +*does*, not a validator on what a preference *is*. + +## API delivery and compatibility + +**This is a coordinated breaking release.** One server version introduces the typed contract, runs +the migration, and removes the legacy string settings surface and the duplicated profile DTO +preference fields. Server, bundled web, Apple, and Android update together. There is no +compatibility shim, no projection of the old API over the new resolver, and no fallback path in +clients. + +Supporting an old client against a new server, or the reverse, is an explicit non-goal. Every +mechanism that would make a mismatched pair partially work is code written to be deleted, and this +subsystem is not worth carrying that. + +### Timing + +`docs/architecture/v1-scope.md` currently reads **"Status: NOT LOCKED — proposal window open,"** and +the amendment process it describes only exists *after* lock. There is therefore no amendment to +write and no exception to request: before lock, removing the legacy settings surface is simply in +scope. + +That argument does not live only here. Reasoning kept in a design doc is invisible to whoever reads +the policy later and sees a removal that appears to break it, so the removal is recorded in the +**pre-lock removals** table in `docs/architecture/v1-scope.md`, which is the file that governs it. +The table also carries the deadline: **this work must ship before the scope locks.** If it has not, +the justification lapses and the removal goes through Deprecation/Sunset like anything else. + +**This is an argument for doing the work now rather than after lock.** After lock, the same removal +would need the Deprecation/Sunset flow the v1 policy mandates and the codebase already implements +(`internal/api/handlers/legacy_read_routes.go`), which reintroduces exactly the transitional +surface this design is avoiding. + +Neither path needs `/api/v2/settings`. A `v2` namespace would imply a whole second API surface this +project does not want to own, for the sake of one subsystem. + +### How a mismatch presents + +Removing the old routes already produces the required outcome. Nothing further is added to enforce +it: + +- An old client calls a removed route and receives `404`. Its settings screens fail. It is not + supported, and the release notes say so. +- A new client detects a pre-contract server by the absence of `GET /api/v1/settings/manifest` and + shows a server-upgrade-required message. This is an error message, not a compatibility path: no + legacy fallback, no local defaults, no partial operation. +- The server-bundled web application is always built from the server's own manifest revision, so it + is exact by construction. + +**No settings version gate is added to the authenticated middleware, and no first-party route +returns `426`.** An earlier revision of this design did exactly that — an +`X-Silo-Settings-Contract-Version` header checked on every authenticated request. It is withdrawn +because it is strictly more code for the same user-visible outcome: header plumbing in four +repositories, a middleware check on every request, and a version constant to maintain, all to +enforce a break that deleting the routes already enforces. + +It is also the wrong shape for a one-time event. A gate in the authenticated chain permanently +couples every endpoint in the product to the settings subsystem's versioning, and the next settings +protocol change inherits an installed base conditioned to expect a global block. Route removal has +no such tail: once the release ships, there is nothing left to maintain. + +Two secondary points reinforce this. `docs/architecture/v1-scope.md` states the house rule as +capability endpoints for feature detection rather than version sniffing, citing +`GET /api/v1/libraries/provider-defaults` — and the manifest endpoint already *is* that capability +endpoint, carrying `api_version` and `revision`. And the header added no detection ability the +manifest endpoint did not already provide; it only added blocking. + +### Post-release revision compatibility + +The coordinated release is exact: every artifact ships against `api_version` 1 at the same manifest +revision. **After it, revisions move independently.** A new setting is one server PR plus *n* +client PRs on their own schedules, governed by the widening/narrowing rules and `introduced_in` +filtering above. + +- `GET /api/v1/settings/capability` returns `api_version` and `revision` for clients that want to + check compatibility without transferring the manifest body. +- Clients filter definitions, scopes, enum members, and bounds against the server's advertised + revision. +- Clients may send `X-Silo-Settings-Contract-Revision` for telemetry about deployed revision + spread. It is diagnostic only and never blocks a request. + +This is the property that keeps the contract from becoming the thing people route around. One +coordinated release is a reasonable cost. A coordinated release for every future setting would not +be, and would push development straight back to unregistered `local.*` keys. + +### Manifest + +`GET /api/v1/settings/manifest` + +- Authenticated but not admin-only. +- Returns the public canonical manifest. +- Supports `If-None-Match` and `304 Not Modified`. +- Never includes current values, secrets, database bindings, or admin-only server configuration. +- Doubles as the capability endpoint for this subsystem: its presence means the contract is + available, and its `api_version`/`revision` fields are the only version negotiation clients need. + +`GET /api/v1/settings/capability` returns `api_version` and `revision` alone, for clients that want +to check compatibility without transferring the manifest body. + +### Explicit stored values + +`GET /api/v1/settings/values?keys=&scope=&` + +- Returns the explicit value and revision at exactly one requested scope; it does not resolve + fallbacks. +- Context parameters are required by scope: `profile_id`, `device_id`, `library_id`, or `series_id` + as defined by the identity table above. +- An unset value is represented as `is_set: false` with no `value` member, never as an empty string + or JSON `null`. +- Settings screens use this endpoint to show profile defaults and device overrides independently. +- Unknown keys, disallowed scopes, and unauthorized contexts are rejected. + +### Effective values + +`GET /api/v1/settings/values/effective?keys=` + +- Requires the active profile and device identity headers for definitions that can resolve those + scopes. +- Rejects unknown keys rather than fabricating defaults. +- Returns native typed values, resolution source, source context, definition revision, + `updated_at`, and any policy constraint. +- A missing explicit value is not an error; resolution continues to the next declared scope. +- Applies `constrained_by` before responding, per **Preferences versus restrictions**. + +`POST /api/v1/settings/values/effective` accepts a batched form for content-scoped resolution: + +```json +{ + "keys": ["playback.audio_language", "playback.subtitle_mode"], + "contexts": [ + { "context_id": "a", "library_id": "42", "series_id": "s-1001" }, + { "context_id": "b", "library_id": "42", "series_id": "s-1002" } + ] +} +``` + +The batched form is not a convenience. `profile_series` and `profile_library` resolution is +per-item, so a season view, a continue-watching row, or any list that needs resolved track +preferences would otherwise issue one request per item. One round trip resolving *n* contexts +against a single prepared query is the required shape; per-item requests are a rejected design. +See **Read path** for the corresponding server-side rules. + +### Mutations + +`POST /api/v1/settings/mutations` + +```json +{ + "mutations": [ + { + "mutation_id": "8cc515ad-88c5-48f0-a6cc-44d0a870e32c", + "operation": "set", + "key": "playback.audio_language", + "scope": "profile_device", + "context": { + "profile_id": "p1", + "device_id": "apple-tv-living-room" + }, + "value": "ja" + }, + { + "mutation_id": "5ae96ffc-1077-4da8-8f64-a1ca9c3c72b8", + "operation": "unset", + "key": "playback.auto_skip_intro", + "scope": "profile_device", + "context": { + "profile_id": "p1", + "device_id": "apple-tv-living-room" + } + } + ] +} +``` + +Server rules: + +1. Reject unknown keys with `unknown_setting`. +2. Reject a scope not listed by the definition with `invalid_setting_scope`. +3. Validate the context and value against the definition before writing. +4. Authorize every context object against the authenticated user. +5. Treat `mutation_id` as idempotent for at least 30 days. Repeating the same ID and body returns + the prior result; reusing an ID with different content returns `mutation_id_conflict`. +6. Return one result per mutation so a batch can retry only transient failures. +7. Apply each mutation atomically. The entire batch need not be transactional across unrelated + keys. +8. Emit a settings-changed event carrying only affected keys/scopes and contract revision; clients + re-fetch effective values rather than trusting event payload values. Events ride the existing + realtime event hub (`internal/events`) on a **new** `user_settings` channel with per-user and + per-profile routing, following the personal-delivery pattern `allowsEventForClaims` already + applies to notifications. The existing `settings` channel is reserved for admin server + configuration: it is declared in `internal/events/types.go` and granted to admins only in + `allowedChannelsForRole`, and although it currently has no publishers, overloading one channel + name for both admin-wide and per-user payloads is a routing mistake waiting to leak. + +HTTP `400` is used for malformed batches. A syntactically valid batch returns `200` with typed +per-mutation results such as `applied`, `already_applied`, `invalid_value`, `forbidden`, or +`transient_failure`. + +Concurrent writes to the same identity are last-write-wins in server receipt order; each write +increments the stored row `revision`. There is no compare-and-set precondition in v1 — settings +are low-frequency user-intent values where the newest explicit choice should win. + +### Removed surfaces + +The release removes, rather than adapts, the old preference surfaces: + +- String-valued `GET`, `PUT`, and `DELETE /api/v1/settings...` handlers. +- Preference fields on profile create/update/response DTOs, including language, subtitle behavior, + skip behavior, quality, and next-up behavior. +- Separate library and series default-language/subtitle mutation routes. Track-selection history may + remain specialized, but user preference defaults move to this contract. +- The open-ended unknown user-setting extension bag. +- The legacy `user_settings` string key/value table itself. Its only non-settings tenant — + jellycompat display-preferences blobs — moves to a dedicated jellycompat store first (see below). +- Client-written raw remote keys and local copies of remote defaults/ranges. + +The unknown-key extension bag deserves specific mention, because it is the mechanism that made all +of this possible. `keyUsesUserScope` in `internal/api/handlers/settings.go` currently returns true +for *any* unregistered key, so a client can invent a production setting unilaterally and the server +will store it. That behavior does not survive the release: after it, unknown keys are always +rejected, and every remaining stored key has a manifest entry or a migration disposition. + +All production reads and writes use the typed manifest, effective-values endpoint, and mutation +endpoint immediately after the release. + +## Jellyfin compatibility surface + +`internal/jellycompat` serves third-party Jellyfin clients (Infuse, Findroid, JellyCon) that Silo +does not control and cannot ask to adopt anything: + +- jellycompat runs on its own router and listener with its own auth middleware. No settings + contract negotiation, header, or gate is ever added to jellycompat routes. Since this design no + longer gates the first-party chain either, this is now a statement of scope rather than an + exemption. +- The hardcoded Jellyfin user `Configuration` DTO and the disposition-based default audio/subtitle + stream selection read none of the retired preference columns and are unaffected. +- `GET`/`POST /DisplayPreferences/{id}` (`internal/jellycompat/handlers_displayprefs.go`) is + affected twice: it persists its blobs through the legacy `user_settings` string store under + `jellycompat:displayprefs:*` keys, and `seedFromProfile` reads the profile `subtitle_language`, + `subtitle_mode`, and `auto_skip_credits` columns this work removes. The release therefore (1) + moves existing display-preferences blobs into a dedicated jellycompat storage table during the + migration and (2) repoints the seed at the canonical resolver. Display-preferences blobs are + Jellyfin client state, not production Silo settings; they do not join the manifest. +- **The seed resolves at profile scope only.** A Jellyfin client has no Silo device identity, so + there is no correct `device_id` to resolve against. Resolving with a synthesized or borrowed + device ID would silently import an unrelated device's overrides into a third-party client, and + registering one would pollute the device registry with rows the user never created. The seed + therefore walks the definition's resolution order with `profile_device` skipped. +- The phase-0 inventory covers jellycompat reads/writes alongside the first-party clients. + +## Canonical storage + +Remote values move to one typed `user_setting_values` table in the same release. The manifest +remains the schema; the database stores validated JSON and scope identity. + +The public contract stays separated from physical storage regardless: internal bindings map a +definition onto its store, and the manifest never exposes table or column names. That indirection +is what lets storage change later without touching a client. It is not a reason to defer the +consolidation — doing so would mean writing bindings to `user_profiles` columns, +`user_device_settings`, `library_playback_prefs`, and `series_playback_prefs` that the migration +then makes obsolete. + +```sql +CREATE TABLE user_setting_values ( + id bigserial PRIMARY KEY, + user_id integer NOT NULL, + key text NOT NULL, + scope text NOT NULL, + profile_id text, + device_id text, + library_id integer, + series_id text, + value jsonb NOT NULL, + revision bigint NOT NULL DEFAULT 1, + created_at timestamptz NOT NULL DEFAULT now(), + updated_at timestamptz NOT NULL DEFAULT now(), + CHECK (scope IN ('account', 'profile', 'profile_device', 'profile_library', 'profile_series')), + CHECK ( + (scope = 'account' AND profile_id IS NULL AND device_id IS NULL AND library_id IS NULL AND series_id IS NULL) OR + (scope = 'profile' AND profile_id IS NOT NULL AND device_id IS NULL AND library_id IS NULL AND series_id IS NULL) OR + (scope = 'profile_device' AND profile_id IS NOT NULL AND device_id IS NOT NULL AND library_id IS NULL AND series_id IS NULL) OR + (scope = 'profile_library' AND profile_id IS NOT NULL AND device_id IS NULL AND library_id IS NOT NULL AND series_id IS NULL) OR + (scope = 'profile_series' AND profile_id IS NOT NULL AND device_id IS NULL AND library_id IS NULL AND series_id IS NOT NULL) + ) +); +``` + +This is the PostgreSQL shape. The per-user SQLite store uses the same columns, checks, and partial +uniqueness but omits `user_id` because the database itself is already user-scoped, and uses the +equivalent SQLite integer/text/JSON-check representation. Both backends run the same store +conformance suite. + +Partial unique indexes enforce one explicit value per identity: + +```sql +CREATE UNIQUE INDEX user_setting_values_account_uq + ON user_setting_values (user_id, key) WHERE scope = 'account'; +CREATE UNIQUE INDEX user_setting_values_profile_uq + ON user_setting_values (user_id, profile_id, key) WHERE scope = 'profile'; +CREATE UNIQUE INDEX user_setting_values_profile_device_uq + ON user_setting_values (user_id, profile_id, device_id, key) WHERE scope = 'profile_device'; +CREATE UNIQUE INDEX user_setting_values_profile_library_uq + ON user_setting_values (user_id, profile_id, library_id, key) WHERE scope = 'profile_library'; +CREATE UNIQUE INDEX user_setting_values_profile_series_uq + ON user_setting_values (user_id, profile_id, series_id, key) WHERE scope = 'profile_series'; +``` + +Delete behavior is application-enforced, not FK-inherited. The per-user SQLite store deliberately +declares no foreign keys, and the existing PostgreSQL preference tables carry no references on +library, series, or device columns, so this table cannot inherit that behavior from constraints. +The PostgreSQL table keeps the cascades that do exist today (user ownership, and composite profile +ownership); everything else — a profile or user delete removing its values, library/series +deletion removing only values scoped to that entity, device forgetting removing `profile_device` +values — is performed by the owning delete paths and verified by the store conformance suite in +both backends. + +Mutation idempotency uses a separate `user_setting_mutations` table keyed by +`(user_id, mutation_id)` with request hash, serialized result, and `expires_at`; rows expire after +30 days. + +`expires_at` is not self-enforcing. A background sweeper deletes expired idempotency rows on the +same schedule and shape as `internal/policy/decisionlog_cleanup.go`, which already solves exactly +this problem for decision logs. Without it the table only grows. `user_setting_migration_rejects` +is bounded by the one-time migration rather than by traffic, so it is retained indefinitely and +removed by the operator, but it is reported in the completion summary so it cannot be forgotten. + +The migration also creates `user_setting_migration_rejects`, an inactive audit table with source +table/key/identity/value and rejection reason. It has no runtime read/write API and is not an +extension bag. Its only purpose is to retain unrecognized or invalid historical rows for operator +inspection instead of silently deleting them. + +### Read path + +The repository's stated priority is performance and reliability first, and this design replaces +narrow purpose-built tables with a generic five-scope table. That trade has to be paid for +explicitly rather than assumed. + +Normative rules: + +1. **One query per resolution request, not one per scope.** Resolving a key with a four-scope chain + issues a single query over the candidate identities, and the resolver ranks the returned rows by + the definition's `resolution_order` in Go. Five sequential index lookups per key per item is a + rejected implementation. +2. **Batched context resolution is the primary read shape** for anything content-scoped. See the + `POST /values/effective` batch form above. A list view resolves *n* items in one round trip and + one query. +3. **The covering index for the hot path is + `(user_id, profile_id, key, scope)`**, in addition to the partial unique indexes, which exist for + correctness rather than for reads. `profile_series` and `profile_library` resolution additionally + needs `(user_id, profile_id, series_id)` and `(user_id, profile_id, library_id)`. +4. **Playback and catalog paths take a snapshot, not per-item resolution.** A session resolves its + settings once at start and carries an effective-preference snapshot, which is what + `internal/catalog/detail.go` and `internal/api/handlers/playback.go` effectively do today with + `Profile.Language`. Re-resolving mid-stream is a correctness hazard as well as a cost. +5. **The release ships with a benchmark against the tables it replaces.** `series_playback_prefs` and + `library_playback_prefs` reads are the baseline; a consolidated read that regresses a hot catalog + or playback path against that baseline blocks the release. Consolidation is a tidiness win, and + a tidiness win does not get to cost latency on a list endpoint. +6. **Account- and profile-scope values are cacheable per request** and should be resolved once per + request rather than per consumer. Device-scope values are cacheable for the life of a session. + +If rule 5 fails, the correct outcome is to keep the specialized tables as permanent bindings. That +is an acceptable end state, not a failure of the contract. + +The one-time migration runs transactionally before the server accepts traffic: + +1. Create and validate the canonical manifest and new tables. +2. Transform known values from account settings, profile columns, device settings, and + library/series preference stores into typed JSON rows using checked-in migration rules. +3. Normalize aliases and values according to the migration table below. +4. Copy unrecognized ad hoc rows to `user_setting_migration_rejects` and include their counts/keys in + the preflight and completion report. They do not become active settings. +5. Quarantine a recognized key whose stored value fails validation and has no normalization rule + into `user_setting_migration_rejects`, reported the same way as unrecognized rows; the setting + becomes unset and resolves to the contract default. Abort only on structural failures — + duplicate identity, row-count/checksum mismatch, or schema errors. Nothing is silently dropped: + every quarantined row appears in the preflight and completion report. +6. Record the completed contract version and manifest revision in the database. +7. Retain specialized track-history fields only when they represent a concrete selected track or + signature rather than a default user setting. + +One narrow exception to "do it all at once" is worth taking, because it costs no code: **the +migration does not `DROP` the columns and tables it supersedes.** It stops reading them and leaves +them in place, unread, to be dropped by a trivial follow-up migration one release later. + +This is not a compatibility path — nothing reads those columns after the release, and no client can +reach them. It is an operator affordance. Omitting a `DROP` statement is free, and it converts +recovery from "restore the pre-upgrade backup and the prior binary together" into "revert the +binary." Given the migration touches two backends and fans out across per-user SQLite databases, +that is worth one deferred cleanup migration. + +Migration atomicity is per database. The PostgreSQL store migrates in one transaction before the +server accepts traffic. Each per-user SQLite database migrates in its own transaction at startup +and records a per-database completion marker. One damaged user database must not prevent the +server from starting for everyone else. + +A user database that fails structurally is quarantined, and the account then operates in +**degraded settings mode**: every definition resolves to its contract default, mutations are +rejected with a typed `settings_unavailable` result, and both the user and the operator see an +explicit error naming the condition. The account is **not** blocked. An earlier revision of this +design blocked "settings-dependent operation," which in practice means playback, browsing, and +resume — an account-wide outage caused by a corrupt preferences database. Falling back to defaults +degrades the experience; blocking removes it. Defaults are always a safe answer, which is the whole +point of having them. + +There is no dual read, dual write, or fallback adapter between the old and new *storage* once a +database has migrated. Operators must take the normal pre-upgrade database backup. + +## Initial canonical scope decisions + +The first manifest must register every official key currently read or written by a supported +client. The following decisions resolve today's duplicate semantics: + +| Canonical setting/family | Persistence and scopes | Migration disposition | +|---|---|---| +| `playback.audio_language` | remote: profile, profile_device, profile_library, profile_series | Migrate profile `language` as the roaming fallback; existing device values become real overrides. | +| `playback.subtitle_language` | remote: profile, profile_device, profile_library, profile_series | Migrate existing profile/library/series subtitle fields to this key. | +| `playback.subtitle_mode` | remote: profile, profile_device, profile_library, profile_series | Existing values are normalized to one enum. | +| `playback.show_forced_subtitles` | remote: profile, profile_device, profile_library, profile_series | Preserve explicit false separately from unset. | +| `catalog.metadata_language` | remote: profile | Migrate existing `preferred_metadata_language` values to this key. Constrained by `profile_preferred_metadata_language` policy input. | +| `playback.preferred_quality` | remote: profile, profile_device | Profile quality is fallback; device override wins. Constrained by account/profile `max_playback_quality` as a `ceiling`. | +| `playback.auto_skip_intro`, `credits`, `recap` | remote: profile, profile_device | Existing profile columns are fallback; explicit device values win. | +| `playback.auto_play_next`, `auto_play_next_preview`, `next_up_prompt_seconds` | remote: profile, profile_device | Use `playback.*`; Android's `player.next_up_prompt_seconds` is migrated and removed from production writes. | +| `subtitle_appearance` | remote: profile, profile_device | Profile value roams; device customization wins. Existing account fallback is copied to each profile. | +| `player.*` technical playback keys | remote: profile_device | HDR, DV, seek cache, speed, sync, gravity, and orientation remain device-specific and server-validated. | +| Theme, text scale/weight, contrast, custom theme variables/CSS | remote: **profile**, profile_device | Existing account rows are copied to every profile on the account; device override for per-screen contrast/scale. Owner-tag all local caches; never apply a cached value to a different authenticated user. | +| Date/time format | remote: **profile** | Existing account rows are copied to every profile. | +| Search media scope | remote: profile | Preserve strict enums. | +| `ui.library_page_state` | remote: profile_device | Keep navigation state tied to one profile/device. | +| OS caption mirroring, platform decoder diagnostics, temporary sleep timers | client_local or private `local.*` | Production caption-mirroring UI is contract-known local; diagnostics/timers remain private local. | + +### Appearance belongs to the profile, not the account + +Theme, text scale, contrast, custom CSS, and date/time format are stored today in `user_settings` +keyed by `user_id`, so they are account-wide. That is an artifact of the storage that predates +household profiles, and this contract should not canonize it — especially given the immutability +rules above, which would make it expensive to revisit. + +Profiles are household members sharing one login. Appearance is the most personal category in the +product, and account scope produces two bad outcomes directly: + +- Everyone in the household shares one theme, one text size, and one contrast setting. A parent who + needs larger text imposes it on everyone, and a child who wants a different theme cannot have one. +- Combined with the account-scope authorization rule below, *any* non-child profile can restyle + every other profile's UI, including the primary's. Nothing about that reads as intentional. + +These keys therefore land at `profile` scope, with the existing account row copied to every profile +during migration — the same deterministic fan-out already specified for subtitle appearance. This +costs one migration rule now and avoids a new-key migration later. + +`account` scope is kept in the model, because genuinely account-wide values exist (billing-style, +security, and account-identity preferences will want it). It simply should not be the default +landing place for anything that is merely stored per-user today. **The inventory in phase 0 must +justify every `account`-scope assignment rather than inheriting it from current storage.** + +The manifest inventory PR must also locate and classify currently unregistered web theme/custom +keys and Android-only keys. An unregistered official key blocks the migration and release. + +### Subtitle appearance migration + +Current subtitle appearance has an account-level legacy fallback plus device overrides. Migration +is deterministic: + +1. Copy the account fallback to every existing profile as that profile's initial value. +2. Keep existing profile-device overrides unchanged. +3. Resolve device → profile → default after migration. +4. Mark migration completion per account so newly created profiles use the contract default rather + than repeatedly copying stale legacy data. + +## Generated client bindings + +Each client vendors a pinned copy of the canonical manifest and generates bindings from it: + +- Go: registry, validators, codecs, public manifest types, and resolver descriptors. +- TypeScript: key union, `SettingValueByKey`, definitions, and validated UI metadata. +- Swift: `SettingKey` constants, Codable value types, scope enums, and default accessors. +- Kotlin: `SettingKey` objects, serializers, scope enums, and default accessors. + +Generated files carry the manifest revision and a “do not edit” header. Handwritten raw remote keys +are forbidden outside migration tests. + +Client CI must fail when: + +- A production remote key literal is not generated. +- A client-local production setting is absent from the shared manifest. +- A local default or range duplicates and disagrees with generated metadata. +- The vendored manifest is malformed or generated files are stale. + +The server manifest PR lands first. Client PRs then update the pinned artifact and generated code. +Every release in the coordinated cutover version set embeds the same protocol version and the exact +same manifest revision, and the pre-release conformance gate verifies that exact set. + +**After the cutover, clients pin whatever revision they were built from** and adopt new revisions on +their own release cadence; revision-aware filtering keeps mixed-revision pairs safe. The cutover is +the only time a matching release is required in another repository. + +## Native synchronization contract + +Apple and Android use a durable outbox for remote mutations. Each entry includes: + +```text +(server_id, user_id, profile_id, device_id, key, scope, operation, typed_value, mutation_id, created_at) +``` + +Required behavior: + +1. Persist the outbox before updating optimistic UI state. +2. Coalesce pending operations only when the complete identity tuple, key, and scope match. +3. Preserve the newest local operation while an older operation is in flight. +4. Remove an entry only after `applied`, `already_applied`, or a deliberate user discard. +5. Retry network/5xx failures with bounded exponential backoff and on app foreground. +6. Keep terminal validation/auth failures visible as a sync error; do not silently log and drop. +7. Flush using the stored server/profile/device context, not the currently selected context. +8. Cancel or quarantine work after logout until the same account/server identity returns. +9. Process `unset` as a first-class operation. +10. Treat a pre-contract server (manifest endpoint absent) as a hold state, not a failure: keep + entries queued, surface the server-upgrade-required message, and resume flushing once the + server is upgraded. Do not drop entries, retry-spin, or attempt a legacy write. +11. Treat a `settings_unavailable` result as retryable, not terminal. It signals a degraded server + store, not a bad mutation. + +Web mutations may remain request-immediate, but caches must be keyed by server, user, profile, +device, and setting scope as applicable. A cached value must never render before ownership matches +the authenticated context. + +## UX requirements + +- Settings screens group profile values separately from device overrides. +- If a definition allows both, the screen shows the effective value and its source. +- “Use profile setting” performs `unset` at `profile_device`; it does not copy the profile value + into the device row. +- Reset actions state their target: **Reset this device**, **Reset this profile**, or **Reset all**. +- Offline edits show a subtle pending indicator. Terminal sync failures show a retry action and a + readable validation message. +- Settings hidden by `platforms` are hidden, not displayed disabled without explanation. +- A setting constrained by policy shows the permitted value with an explanation of the limit, and + offers only `permitted_values`. A `locked` constraint shows a lock affordance and states who set + it — never a disabled control with no reason. +- When a stored preference exceeds a current restriction, the screen says so rather than silently + rewriting the user's choice. The stored preference is still theirs; it is just capped today. +- Admin device views render controls from the canonical manifest and may clear remote overrides. + They do not claim access to client-local values. +- Apple’s current subtitle copy — explicitly separating profile behavior from per-device appearance + — is the UX baseline to retain and generalize. + +## Validation and authorization + +- Validation occurs in the server contract layer before any setting value is stored. Validation + checks a value against its *definition*; it does not apply policy restrictions — see + **Preferences versus restrictions**. +- Profile DTOs no longer contain preference fields, so profile identity/access updates cannot bypass + settings validation. +- The authenticated user may mutate owned profiles according to existing profile permissions. +- Account-scope values affect every profile on the account, so account-scope mutations require the + **primary** profile. Child profiles and ordinary non-primary profiles may read them but not + write them. UX copy for account-scope settings states that they apply to the whole account. + Restricting the write to the household parent matches what `is_primary` already means; allowing + any non-child profile to change a value every other profile sees is an authorization gap, not a + convenience. +- Device mutations require a non-empty bounded device ID and register/update device metadata. +- Library/series settings require access to the referenced content scope. +- Admin clear/reset operations are audited. +- Settings values must never contain secrets. A future secret-like preference requires a dedicated + encrypted/credential API, not a new settings schema type. + +## Coordinated release plan + +Implementation is split across PRs, but none of the new clients or breaking server routes are +released independently. The deployable unit is one version set containing the server, bundled web, +Apple clients, and Android clients built against contract version `1` at the same manifest revision. + +### Phase 0 — freeze and inventory + +- Stop adding ad hoc remote key literals in every repository. +- Inventory server, web, Apple, Android, and jellycompat reads/writes. +- Classify every production setting and record aliases, current defaults, ranges, and consumers. +- Justify every proposed `account`-scope assignment rather than inheriting it from current storage. +- Identify every definition that a policy input constrains. +- Define a migration disposition for every discovered stored key and profile preference column. + +### Phase 1 — ship the #376 P1 fixes independently + +These do not depend on the contract and should not wait for it: + +- Fix Apple audio language so a stored value affects selection. +- Fix Android's `player.` → `playback.next_up_prompt_seconds` alias, the `4.0` → `3.0` speed clamp, + and the `dv_profile7_hdr10_fallback` default. +- Remove Android's unregistered device-setting writes. +- Replace Apple and Android pending-write logic with durable scoped outboxes. +- Owner-tag web theme and custom-style caches. + +Shipping these first keeps the contract release purely structural and stops user-visible bugs from +being held to the migration's schedule in either direction. + +### Phase 2 — contract and storage + +- Add `contracts/settings/v1` and manifest validation tests. +- Register all official current keys, including web theme/customization keys. +- Add canonical storage, mutation idempotency storage and its sweeper, and the one-time migration. +- Apply `constrained_by` in the resolver, wired to `internal/policy`. +- Add manifest, capability, values, effective-values (single and batched), and mutation routes. +- Add the `user_settings` event channel with per-user routing. +- Generate Go/TypeScript registry code from the manifest. +- Keep the new routes behind an unreleased build gate until the client work is ready. + +### Phase 3 — canonical resolution + +- Move profile, account, device, library, and series defaults to canonical values. +- Make playback/catalog paths consume the canonical resolver and its permitted values. +- Remove preference fields and mutation behavior from profile/library/series DTOs. +- Close the unknown-key extension bag. +- Repoint the jellycompat DisplayPreferences seed at the canonical resolver at profile scope, and + move its blobs to dedicated jellycompat storage. + +### Phase 4 — clients + +- Generate and adopt Swift/Kotlin/TypeScript bindings. +- Replace raw key literals with generated types. +- Add the standardized scope/source/constraint UX. +- Add server-upgrade-required messaging keyed on the manifest endpoint being absent. + +### Pre-release gate + +- All four repositories pass the shared conformance fixture at the exact commits selected for the + release. +- Migration is rehearsed against anonymized copies representing SQLite and PostgreSQL user stores, + including invalid/unknown-value failure cases. +- The read-path benchmark shows no regression against the specialized tables being replaced. +- Store-distributed Apple/Android builds are approved and available before the server release is + published. +- Release notes name the server build to pull alongside the client versions. `silo-android` + publishes plain versions to Play Store and `silo-server` ships as Docker `latest` off the default + branch, so the notes carry the pairing that image tags do not. +- Release notes state that server and apps must be upgraded together and that rollback requires + reverting the binary, or restoring the pre-upgrade backup once the follow-up migration has + dropped the superseded columns. +- Server startup reports a migration preflight summary. + +### Cutover + +1. Operator takes the required database backup. +2. Operator upgrades the server; startup runs the migration transaction and contract validation. +3. Server serves the matching bundled web client. +4. Users update Apple/Android clients. Mismatched clients receive `404` on removed routes; new + clients against an old server show server-upgrade-required. +5. No old settings route or schema remains active after the migration commits. + +### Rollback + +Reverting the binary alone is **not** sufficient, and the reason is specific: the +DisplayPreferences move deletes the `jellycompat:*` rows from `user_settings` once it has +copied them, and the previous binary reads exactly those rows. An older server therefore +starts cleanly and silently serves defaults, so every Jellyfin client's saved view +preferences look reset. The settings backfill does not have this problem — it only derives +new rows and never touches the legacy tables. + +Order matters: + +1. Stop the server. +2. Roll the schema back before re-deploying the old binary: + `make migrate-down-to VERSION=`. This is a dedicated command rather + than the `goose` CLI because the backfill and the DisplayPreferences move are Go + migrations registered in-process, which the standalone CLI cannot see or reverse. +3. Deploy the previous binary. + +**`down-to` is a range, not a list, and this release is not contiguous.** The settings work +is spread either side of migrations that belong to other features: `20260727010621` +(settings tables) and `20260728132327` (the DisplayPreferences move) sit around +`20260727212045_invitations` and `20260727220010_profile_onboarding`, both of which are +older-binary migrations. Goose walks down from the newest applied version and stops at the +one named, so it reverts everything in between — and `profile_onboarding`'s down is +`DROP TABLE user_profile_onboarding`, which discards every profile's onboarding-tour state. + +So there is no version that undoes only this release: + +- `VERSION=20260728132326` reverts just the DisplayPreferences move — the destructive half, + and the one that matters for a binary rollback. Prefer this when the goal is simply + "let the old binary find its jellycompat rows again." +- `VERSION=20260727212045` additionally reverts the settings tables, and takes + `profile_onboarding` with it. Only use it if you accept losing tour state, or if you are + restoring from backup anyway. + +Two caveats an operator has to know before upgrading: + +- **Take a database backup first.** The rollback path is exercised by a test + (`internal/database/migrate_downto_test.go`), but a backup is the only recovery once the + follow-up migration drops the superseded columns — and, given the interleaving above, the + only way to undo this release without collateral. +- **Rolling back discards settings written while the new binary was live.** The canonical + write path does not mirror into the legacy tables, so `rollbackSettingValues` drops those + changes; users revert to their pre-upgrade preferences rather than to defaults. +- **The per-user SQLite backend cannot be rolled back at all.** Its migrations are + version-numbered with no down path, and an older binary refuses to open a database newer + than it knows (`internal/userdb/migrate.go`), so every per-user store fails to open and + the rollback is an outage rather than a degradation. Installs on `userdb.backend: sqlite` + must restore from backup. The default backend is PostgreSQL. + +### Post-cutover cleanup + +- Verify migrated counts/checksums and effective-value samples. +- Add stale empty-device cleanup and Forget device UX. +- Retain the one-time migration as an inert historical migration unless Silo's release policy + permits skipping directly to newer versions. + +## Testing + +### Contract tests + +- Manifest validates against its schema and has a stable digest. +- Every default validates against its type. +- Every resolution chain references allowed scopes exactly once and ends with `default`. +- Generated Go, TypeScript, Swift, and Kotlin outputs are reproducible. +- Every stored legacy source key/column has exactly one migration disposition. +- Every additively introduced enum member, scope, and widened bound carries an `introduced_in` + revision, and no `introduced_in` exceeds the manifest revision. +- A manifest change that narrows a scope, tightens a range, removes an enum member, or changes a + value type fails the compatibility check without a new key. +- Every `constrained_by.policy_input` names a field `internal/policy` actually produces, and a + `ceiling`/`floor` constraint is declared only on an ordered enum or a numeric type. + +### Server tests + +- Native boolean/number/object round trips. +- Unknown key, invalid type, invalid range, invalid enum, invalid scope, and unauthorized context + rejection. +- Set versus unset distinction for false, zero, empty string, and nullable values. +- Effective resolution for every declared chain, especially series → library → device → profile. +- Mutation idempotency and ID/body conflict. +- Per-mutation partial retry behavior. +- One-time migration success, atomic failure, alias normalization, row-count/checksum verification, + and restart after completed migration. +- Revision tolerance in both directions: an older-revision client is accepted, and a newer-revision + client's unknown definitions, enum members, and scopes are filtered rather than rejected. +- No route in the first-party chain returns `426`, and no settings version check exists in the + authenticated middleware. +- Removed routes return `404`; no legacy settings handler or profile DTO preference field survives. +- Policy constraint: an effective value is capped to the permitted value, `requested_value` is + reported, `permitted_values` narrows correctly, and a mutation exceeding a restriction is + **stored** rather than rejected and takes effect when the restriction is lifted. +- Degraded settings mode returns contract defaults and `settings_unavailable` instead of blocking + the account. +- Batched effective resolution returns the same results as *n* single-context calls, in one query. +- jellycompat DisplayPreferences seeding from the canonical resolver at profile scope with + `profile_device` skipped, and blob survival across the store move. +- Incognito/new-device fallback without copying another device override. +- Empty stale-device retention cleanup and idempotency-row expiry sweeping. + +### Client tests + +- Generated key/type use, and revision-aware filtering of definitions, enum members, and scopes. +- A pre-contract server produces a server-upgrade-required message rather than an unhandled error, + an empty settings screen, or a crash. +- New sign-in/incognito receives profile values but not another device override. +- Profile switch and server switch cannot redirect queued writes. +- Process death preserves outbox entries. +- Failed writes remain queued and visible. +- Cache ownership prevents cross-account flashes. +- UI copy accurately names scope and reset behavior. + +### Cross-platform conformance fixture + +The contract directory includes a fixture set of definitions, explicit values, contexts, and +expected effective results. Server, web, Apple, and Android run the same fixture cases. This is the +gate that catches key, default, type, and precedence drift. + +It gates the coordinated release at the exact commits selected for it, and it stays afterwards as a +**per-repository CI gate**: each repository runs it against its pinned manifest revision on every +PR. The second role is the durable one. Checking four commits once at release time catches drift +that already exists; running it per PR catches drift as it is introduced, which is what keeps the +contract true once releases stop being coordinated. + +## Acceptance criteria + +- A production user-facing setting cannot land in a client without a canonical manifest entry. +- A private `local.*` knob cannot be sent to the server. +- The server rejects unknown keys and invalid typed values. +- Swift, Kotlin, TypeScript, and Go use generated key/type bindings. +- Profile language, subtitle, and appearance preferences roam into a new incognito session. +- Device overrides do not roam into a different device identity. +- Effective responses explain where values came from and whether policy constrained them. +- A client can never present a choice that policy will refuse, and a stored preference is never + destroyed by a restriction. +- Apple and Android persist failed mutations with full server/profile/device identity. +- The verified Android key/default/range drift and Apple no-op audio preference are covered by + conformance tests. +- Only the primary profile can mutate account-scope values. +- The one-time migration either completes and verifies atomically or leaves the database unchanged. +- A quarantined per-user database degrades that account to contract defaults; it does not block the + account or the server. +- No hot catalog or playback read regresses against the specialized tables it replaces. +- jellycompat routes carry no contract negotiation, and its DisplayPreferences seed and storage no + longer depend on removed profile columns or the legacy string settings store. +- No old string settings route, open-ended key bag, or duplicated profile preference field remains + after cutover. +- No settings version check exists in the authenticated middleware, and no first-party route + returns `426`. A mismatched client fails because the routes are gone, not because a gate refused + it. +- **After the cutover, adding a setting requires no coordinated release.** A server manifest PR can + ship alone, and each client adopts the new revision on its own cadence. + +## Required PR workflow for a new setting + +1. Open a `silo-server` PR that adds the manifest definition, default, scopes, resolution order, + UX copy, persistence class (or `client_local` declaration), any `constrained_by` binding, + `introduced_in` revision, and contract tests. +2. Merge the contract PR before merging a production client implementation. +3. Update the client’s pinned manifest and regenerate bindings. +4. Implement the UI/consumer using generated types, filtering against the server's advertised + revision. +5. Add the cross-platform fixture when the setting has resolution, constraint, or coercion behavior. + +Steps 3 and 4 happen on each client's own schedule. A new setting is one server PR plus *n* +independent client PRs, never a synchronized release. That property is the reason the contract can +be strict without becoming the thing people route around. + +This server-first PR requirement is intentional governance, not a requirement that every value be +stored by the server. It keeps the vocabulary, types, defaults, and UX semantics consistent while +preserving a clearly bounded client-local storage option. diff --git a/go.mod b/go.mod index 139ee154..1ab63618 100644 --- a/go.mod +++ b/go.mod @@ -33,6 +33,7 @@ require ( github.com/open-policy-agent/opa v1.18.2 github.com/pgvector/pgvector-go v0.3.0 github.com/pressly/goose/v3 v3.27.1 + github.com/santhosh-tekuri/jsonschema/v6 v6.0.2 github.com/tetratelabs/wazero v1.12.0 github.com/wneessen/go-mail v0.7.3 github.com/zishang520/socket.io/v2 v2.5.0 @@ -80,7 +81,6 @@ require ( github.com/quic-go/quic-go v0.60.0 // indirect github.com/quic-go/webtransport-go v0.11.1 // indirect github.com/rcrowley/go-metrics v0.0.0-20250401214520-65e299d6c5c9 // indirect - github.com/santhosh-tekuri/jsonschema/v6 v6.0.2 // indirect github.com/segmentio/asm v1.2.1 // indirect github.com/sethvargo/go-retry v0.3.0 // indirect github.com/sirupsen/logrus v1.9.4 // indirect diff --git a/internal/access/metadata_language.go b/internal/access/metadata_language.go new file mode 100644 index 00000000..4d2998f7 --- /dev/null +++ b/internal/access/metadata_language.go @@ -0,0 +1,34 @@ +package access + +import ( + "context" + + "github.com/Silo-Server/silo-server/internal/userstore" +) + +// PreferredMetadataLanguage resolves catalog.metadata_language canonically for +// one profile: the stored profile-scope value, else the contract default.
