🔒️(backend) audit writes made through the Django admin

Every ModelAdmin now emits an ECS audit event when an object is created,
changed or deleted, and when a bulk action runs. Actions are templated
as admin.<target>.<verb>, after the model name. A signed-in account
without staff access reaching the admin is recorded as a denied
admin.access.

The wiring is a custom AdminSite installed through AdminConfig.default_site:
it mixes the auditing into every admin class at registration, including the
ones Django declares, so a new ModelAdmin is covered without doing anything.
It hangs off log_addition, log_change, log_deletions and get_actions, which
Django calls in every path, rather than off save_model. Deletions noted by
log_deletions are emitted from delete_model and delete_queryset, once their
outcome is known.

Changed field names are always reported; their values only for the
admin_values each model is registered with, and never for anything that
looks like a secret. An account acted upon is reported as user.target.

 ### Helm chart: media services default to Garage
 
 The `meet` chart now defaults `serviceMedia.host` and `serviceMediaFiles.host` to `garage.meet.svc.cluster.local`, and the `upstream-vhost` annotation of `ingressMedia` and `ingressMediaFiles` to `garage.meet.svc.cluster.local:9000`. If you relied on the former `minio.meet.svc.cluster.local` defaults, set these values explicitly to your S3 service before upgrading, or recordings and files stop being served under `/media`.
+### Recording encoding settings replaced by a resolution/profile model
+
+The `RECORDING_ENCODING_*` settings introduced in v1.16.0 exposed raw encoder
+values (width, height, framerate, bitrate). They are replaced by two named and configurable sets of
+dimensions, a **resolution** (default: `540p`, `720p`, `1080p`) and a **profile**
+(default: `talking_heads`, `text`, `mixed`, `full`), which are resolved to the width, height,
+fps and video bitrate.
+
+**The following environment variables are no longer read. If they are still set in
+your deployment they are silently ignored, and your recordings will be encoded with
+the new defaults instead of your tuned values.**
+
+| Removed variable                        | Replaced by                                                                                                   |
+| --------------------------------------- | ------------------------------------------------------------------------------------------------------------- |
+| `RECORDING_ENCODING_ENABLED`            | Nothing. A default encoding is now always built (see below). **Not** `RECORDING_CUSTOM_ENCODING_ENABLED`, which gates a different feature. |
+| `RECORDING_ENCODING_WIDTH`              | The `width` of the entry selected by `RECORDING_ENCODING_DEFAULT_RESOLUTION` in `RECORDING_ENCODING_AVAILABLE_RESOLUTIONS`. |
+| `RECORDING_ENCODING_HEIGHT`             | The `height` of that same entry.                                                                              |
+| `RECORDING_ENCODING_FRAMERATE`          | The `fps` of the profile selected by `RECORDING_ENCODING_DEFAULT_PROFILE` in `RECORDING_ENCODING_AVAILABLE_PROFILES`. |
+| `RECORDING_ENCODING_VIDEO_BITRATE_KBPS` | That profile's `kbps`.                                                                  |
+
+`RECORDING_ENCODING_AUDIO_BITRATE_KBPS` and `RECORDING_ENCODING_KEY_FRAME_INTERVAL_S`
+keep their names and meaning. The keyframe interval now defaults to `0` (unset,
+encoder's choice) instead of `4.0`.
+
+#### If you never set `RECORDING_ENCODING_ENABLED=True`
+
+The shipped defaults (`RECORDING_ENCODING_DEFAULT_PROFILE=full`,
+`RECORDING_ENCODING_DEFAULT_RESOLUTION=720p`) match LiveKit's built-in
+`H264_720P_30` preset: 1280×720, 30 fps, 3000 kbps H.264 MAIN, 128 kbps AAC.
+Video output is therefore unchanged.
+
+Audio and keyframing may not be. These values are now sent explicitly as advanced
+`EncodingOptions` rather than relying on LiveKit's preset, so
+`RECORDING_ENCODING_AUDIO_BITRATE_KBPS` and `RECORDING_ENCODING_KEY_FRAME_INTERVAL_S`
+now apply to every recording. They previously applied only when
+`RECORDING_ENCODING_ENABLED` was `True`. **If you set either of them while the
+feature was disabled, they had no effect and now do**; check them before upgrading.
+
+If you never set them, no action is required: 128 kbps AAC is what the preset used,
+and the keyframe interval now defaults to `0`, which leaves the field unset so the
+encoder keeps picking it as before. Set `RECORDING_ENCODING_KEY_FRAME_INTERVAL_S=4.0`
+if you want fixed 4-second keyframes (the value the setting defaulted to while it
+was gated behind `RECORDING_ENCODING_ENABLED`).
+
+To keep letting LiveKit pick the encoding instead, set either default to an empty
+value:
+
+```
+RECORDING_ENCODING_DEFAULT_RESOLUTION=
+RECORDING_ENCODING_DEFAULT_PROFILE=
+```
+
+#### If you had tuned `RECORDING_ENCODING_*` values

+Translate your old values into a default resolution and a default profile. Declare your own resolution and/or profile. Both maps are read from the
+environment as a single-line Python/JSON dict literal (parsed with
+`ast.literal_eval`, so use double-quoted keys and no trailing commas, and do not
+add outer quotes in `.env`-style files):
+
+```bash
+RECORDING_ENCODING_AVAILABLE_RESOLUTIONS={"540p": {"width": 960, "height": 540}, "720p": {"width": 1280, "height": 720}, "1080p": {"width": 1920, "height": 1080}}
+RECORDING_ENCODING_AVAILABLE_PROFILES={"my_old_profile": {"fps": 15, "kbps": {"540p": 350, "720p": 600, "1080p": 1100}}}
+RECORDING_ENCODING_DEFAULT_RESOLUTION=720p
+RECORDING_ENCODING_DEFAULT_PROFILE=my_old_profile
+```
+
+Both maps are validated at startup and a malformed one raises a `ValueError`:
+
+- every entry of `RECORDING_ENCODING_AVAILABLE_RESOLUTIONS` must declare `width` and
+  `height`, and every entry of `RECORDING_ENCODING_AVAILABLE_PROFILES` an `fps` and a
+  `kbps` map;
+- every profile must define a `kbps` entry for **exactly** the keys of
+  `RECORDING_ENCODING_AVAILABLE_RESOLUTIONS`; overriding one of the two maps usually
+  means overriding both;
+- `RECORDING_ENCODING_DEFAULT_RESOLUTION` and `RECORDING_ENCODING_DEFAULT_PROFILE`,
+  when non-empty, must be keys of their respective map.
+
+#### Breaking: custom worker services must accept `encoding_options`
+
+Only concerns deployments pointing `RECORDING_WORKER_CLASSES` at their own worker
+class. The shipped `VideoCompositeEgressService` and `AudioCompositeEgressService`
+are already updated.
+
+The `WorkerService` protocol's `start()` takes a third argument, and the mediator
+now always passes it as a keyword when the recording carries no per-recording encoding:
+
+```python
+# before
+def start(self, room_id: str, recording_id: str) -> str: ...
+
+# now
+def start(
+    self,
+    room_id: str,
+    recording_id: str,
+    encoding_options: Optional[Dict[str, Any]] = None,
+) -> str: ...
+```
+
+#### Optional: per-recording encoding
+
+`RECORDING_CUSTOM_ENCODING_ENABLED` (default `False`) toggles whether the
+start-recording API accepts an `encoding` object
+(`{"resolution": "720p", "profile": "talking_heads"}`, `profile` optional. It
+falls back to `RECORDING_ENCODING_DEFAULT_PROFILE`) that overrides the default for
+a single recording. It does not enable or disable the
+default encoding, which is built from the two `RECORDING_ENCODING_DEFAULT_*`
+settings either way. Leaving it at `False` preserves the previous behaviour, where
+every recording uses the server-side encoding: requests carrying
+`options.encoding` are rejected with a `400` before the recording is created, so
+nothing is persisted and no egress is started.
+
+Before enabling it:
+
+- clients can only pick keys you declared; there is no way to send a raw width or bitrate
+- as of this implementation, the frontend never sends `encoding` 
+- `encoding` is accepted but ignored for `transcript` recordings, whose audio-only
+  egress has no video encoding to configure.
+
+See [docs/features/recording.md](docs/features/recording.md#tuning-recording-encoding)
+for the full setting reference, the shipped profile table and the tuning caveats.

+# Audit logging
+
+La Suite Meet emits a structured **audit log**: one JSON line per notable action, saying who did what, on behalf of
+whom, on which resource, from where, and whether it succeeded.
+
+## What an event looks like
+
+Events are written on the dedicated `audit` logger, one per line and look like this: 
+
+```json
+{
+  "@timestamp": "2026-09-15T08:41:12.345+00:00",
+  "ecs": {"version": "8.11.0"},
+  "log_type": "audit",
+  "service": {"name": "meet", "environment": "production"},
+  "event": {
+    "kind": "event",
+    "action": "room.create",
+    "category": ["api"],
+    "type": ["creation"],
+    "outcome": "success"
+  },
+  "trace": {"id": "6f1c0d0e2a8b4c1d9e7f0a1b2c3d4e5f"},
+  "client": {"ip": "1.2.3.4"},
+  "source": {"ip": "1.2.3.4"},
+  "http": {"request": {"method": "POST"}},
+  "url": {"path": "/external-api/v1.0/rooms/"},
+  "user": {"id": "beecd833-4be4-4675-b139-a196b07144a9", "sub": "0edebfa3-1355-4891-ae63-daf9fd37ac04", "domain": "gouv.fr"},
+  "organization": {"id": "calendar-app"},
+  "lasuite": {
+    "actor": {"type": "application"},
+    "auth": {"method": "application_jwt"},
+    "application": {"client_id": "calendar-app"},
+    "outcome": "success",
+    "target": {"type": "room", "id": "3b1d…", "slug": "daily-standup", "name": "Daily standup", "access_level": "trusted"}
+  },
+  "log": {"level": "info", "logger": "audit"}
+}
+```
+
+A refusal is recorded under the action that was attempted: the same `room.create`, with
+`"event": {"outcome": "failure", "type": ["creation", "denied"], "reason": "permission_denied"}`,
+`"lasuite": {"outcome": "denied"}`, `"http": {"response": {"status_code": 403}}` and `"error": {"message": "…"}`.
+
+## Fields
+
+Standard fields follow the [Elastic Common Schema](https://www.elastic.co/guide/en/ecs/current/index.html);
+
+| Field | Meaning |
+|---|---|
+| `@timestamp` | ISO 8601 with millisecond precision in UTC timezone` |
+| `log_type` | Always `audit` |
+| `service.name`, `service.environment` | `AUDIT_LOG_SERVICE_NAME` and current environment |
+| `event.action` | What was attempted, from the catalogue below |
+| `event.category`, `event.type` | ECS classification (`api`, `authentication`, `iam`... / `creation`, `change`, `access`, `denied`, `user`...) |
+| `event.outcome` | ECS `success` or `failure` |
+| `event.reason` | Why it did not succeed: `authentication_failed`, `permission_denied`, `rate_limited`, `validation_error`, `not_found`, `conflict`, `internal_error` |
+| `lasuite.outcome` | `success`, `failure` or `denied` |
+| `lasuite.actor.type` | `user`, `application`, `device`, `service`, `system` or `anonymous` |
+| `lasuite.actor.name` | Name of a service actor |
+| `lasuite.auth.method` | `session`, `application_jwt`, `addons_jwt`, `resource_server`, `livekit_token`, `shared_secret`, `client_credentials`, `oidc`, `password`, `none`, or `unknown` for a class that is not registered. Requests served outside DRF, as the admin and logout are, report `session` when signed in |
+| `lasuite.application.client_id` | The external application acting, when there is one. Only set once its credentials are verified |
+| `user.id`, `user.sub`, `user.domain` | The (delegated) human user: primary key, OIDC sub when the account has one, and email domain. The email address is never recorded |
+| `user.target.id`, `user.target.sub`, `user.target.domain` | The account an IAM action was performed on, when the target is a user. `user.*` stays the actor |
+| `organization.id` | Tenant: the application client id when present, else the user's email domain |
+| `lasuite.target` | The resource acted on: `type`, `id` and a few stable fields per type |
+| `lasuite.details` | Action-specific fields (see catalogue) |
+| `client.ip`, `source.ip` | Real client address, the one DRF's throttles identify (see `NUM_PROXIES`) |
+| `http.request.method`, `url.path` | Request as received |
+| `http.response.status_code` | Set on refusals and failures |
+| `trace.id` | Request id, also echoed as the `X-Request-ID` response header and logged by Gunicorn as `rid=`. Generated by the backend unless `REQUEST_ID_TRUST_HEADER` is set |
+| `error.message` | Human-readable reason of a failure |
+| `error.type` | Class of an unhandled exception. Its message is left out, as it may carry personal data |
+| `log.level` | `info` for success, `warning` for failures and denials, `error` for internal errors |
+
+An audited API action that raises an exception DRF does not handle is still recorded, as a `failure` with reason
+`internal_error`, status code `500` and `error.type`, before the exception propagates.
+
+## Catalogue
+
+| `event.action` | Emitted when | Notable fields |
+|---|---|---|
+| `application.token.issue` | An application requests a delegated token (`POST /external-api/v1.0/application/token/`), whether it obtains one or is refused: bad credentials, inactive application, invalid or unauthorized email domain, unknown user, provisioning conflict | On success: `user.*` = delegated user, `lasuite.target` = application, `lasuite.details.scopes`, `user_provisioned`, `expires_in`. On refusal: `event.reason`, `http.response.status_code`, `lasuite.details.requested_domain`. Until the credentials are verified, the submitted client id is only `lasuite.details.claimed_client_id`: it never sets `lasuite.application` or `organization` |
+| `user.provision` | An application creates a provisional user by email | `lasuite.target` = user |
+| `room.create` | A room is created through the external API, or the attempt fails | `lasuite.target` = room |
+| `room.update` | A room is updated through the external API, or the attempt fails | `lasuite.target` = room, refusals included, `lasuite.details.updated_fields`, `previous_access_level` |
+| `room.retrieve` | A room is read through the external API, or the attempt fails | `lasuite.target` = room |
+| `room.list` | Rooms are listed through the external API, or the attempt fails | `lasuite.details.total` |
+| `user.login` | A user logs in or a login attempt fails | `lasuite.auth.method` = `oidc` or `password`, or `unknown`: named after the backend on success, `lasuite.details.auth_backend`, and after the credentials submitted on failure (a password, or the nonce of the OIDC callback) |
+| `user.logout` | A user logs out | |
+| `admin.access` | A signed-in account without staff access reaches an admin page (always denied), once per refused page | `event.reason`, `http.response.status_code`: the redirect to the login page |
+| `admin.<target>.<verb>` | A write is made through the Django admin, see below | |
+
+Actions are always dotted, lower-case, with the format `<target>.<verb>`, and name what was attempted: whether it
+succeeded is told by `event.outcome`, `lasuite.outcome` and `event.reason`, never by the action.
+
+## Django admin
+
+The admin is the most sensitive surface of the product, so every write made through it emits an audit event next to
+the `LogEntry` Django writes itself. Nothing is replaced and there is no extra table: the admin history keeps working.
+
+The action is templated rather than listed: `admin.<target>.<verb>`, where `<target>` is the model name and `<verb>`
+one of:
+
+| `<verb>` | Emitted when | Notable fields |
+|---|---|---|
+| `create` | An object is added | `lasuite.details.changed_fields`, `changes` |
+| `update` | An object is changed | `lasuite.details.changed_fields`, `changes` |
+| `delete` | An object is deleted, one event per object, once the deletion has run. A deletion that raises is a `failure` with reason `internal_error`; in a bulk deletion every selected object is then reported as failed | `error.message` on failure |
+| `action` | A bulk action runs | `lasuite.details.admin_action`, `count` |
+
+So `admin.room.update`, `admin.user.delete`, `admin.recording.action`. `event.category` is `iam` for anything granting
+access to the product and `configuration` otherwise. Writes on a user or a group lead `event.type` with `user` or
+`group`, as in `["user", "change"]`.
+
+`lasuite.details.changed_fields` always carries the **names** of the fields a form changed, exactly the ones Django
+reports in its own history. `lasuite.details.changes` carries their **values**, as `{"from": ..., "to": ...}`, and only
+for the fields a model explicitly allows in the `admin_values` it is registered with. Anything that
+looks like a secret is refused there whatever the allow-list says, so a password change is reported as a change to `password` and never with its value.
+A `JSONField` on the allow-list, such as a room's `configuration`, is recorded as JSON rather than stringified, and both versions are kept
+whole.
+
+Objects edited through an **inline** emit their own event, joined to the parent's by `trace.id`: granting a role on a
+room produces both `admin.room.update` and `admin.resourceaccess.create`.
+
+What is deliberately **not** covered:
+
+- **Reads.** Opening a change list, a change form or the history page emits nothing. Django's own `LogEntry` remains
+  the record of who touched what.
+- **A custom action bypassing the ORM hooks.** An action calling `queryset.update()` or `queryset.delete()` directly
+  is reported as `admin.<target>.action` with its name and the number of objects, not one event per object.
+  `delete_selected` is the exception: Django reports its objects through `log_deletions`, so it emits one
+  `admin.<target>.delete` each and no `action` event.
+
+The wiring lives in `core/audit/admin.py`: `AuditedAdminSite` mixes the auditing into every admin class at
+registration, including those declared by Django itself, and is installed through
+`core.audit.apps.AuditedAdminConfig` in `INSTALLED_APPS`. A new `ModelAdmin` is therefore covered without doing
+anything; registering its model (see below) only adds its category and its allowed values.
+
+## Emitting events
+
+Actions are declared once, in `core/auditing.py`, as `audit.Action` constants. An action may carry its ECS category
+and types, which then apply to every event it emits:
+
+```python
+APPLICATION_TOKEN_ISSUE = audit.Action(
+    "application.token.issue",
+    category=EventCategory.AUTHENTICATION,
+    types=(EventType.START,),
+)
+ROOM_CREATE = audit.Action("room.create")
+```
+
+DRF views declare the actions they audit; everything else is derived from the response. CRUD actions are mapped in
+`audit_actions`, and an extra action names its own on its route, so that renaming its method cannot silently stop
+auditing it:
+
+```python
+from core import audit, auditing
+
+
+class RoomViewSet(audit.AuditViewMixin, viewsets.GenericViewSet):
+    audit_actions = {"create": auditing.ROOM_CREATE, "retrieve": auditing.ROOM_RETRIEVE}
+
+    def perform_create(self, serializer):
+        self.audit_target = serializer.save()
+
+    @action(detail=True, methods=["post"], audit_action=auditing.ROOM_INVITE)
+    def invite(self, request, pk=None): ...
+```
+
+- **Views are audited by `AuditViewMixin`** from DRF's `finalize_response` hook, which runs for every response,
+successful or not. The ECS category and types come from the action, else `api` and the DRF action (`creation` for
+`create`...). The outcome, reason and status code come from the response status: 401, 403 and 429 are `denied`, other
+errors `failure`, and a 401 is always filed under `authentication`. The target is the object `get_object()` returned,
+unless the view assigns `audit_target`. A view can also assign `audit_actor` and `audit_details`, or override
+`get_audit_fields()`. `audit_actions` only accepts CRUD actions: any other key raises a `TypeError` when the class is
+defined.
+
+- **Anything else calls `audit.log`** with the request at hand. A `category` or `types` given here wins over the
+action's:
+
+  ```python
+  audit.log(auditing.USER_PROVISION, request=request, target=user)
+  ```
+
+- **Request fields are read from `request`**: the real client address and the path. The trace id is the request id,
+settled by `RequestIdHeaderMiddleware` right after dockerflow assigned it, and echoed in the
+`DOCKERFLOW_REQUEST_ID_HEADER_NAME` response header (`X-Request-ID` by default). The inbound id is kept only when
+`REQUEST_ID_TRUST_HEADER` is set; otherwise the backend generates one, so a client never picks it.
+
+- **Actors are derived** from `request.user`, `request.auth` and the DRF authenticator, whose class is mapped to an
+auth method by `audit.register_auth_method` (see Configuration). It is possible to override the actor with `actor=`,
+`actor_type=`, `auth_method=` and `client_id=`.
+
+- **Targets are described** by their model name, primary key and the `fields` their model is registered with. A model
+that is not registered is still identified. Extra keyword arguments land under `lasuite.details`.
+
+- **Emission never raises.** A broken configuration or value is reported on the application logger (and Sentry) and the
+business operation proceeds. A registered field that cannot be read is left out of the target, and the event is still
+emitted.
+
+## Configuration
+
+| Variable | Default | Meaning |
+|---|---|---|
+| `AUDIT_LOG_LEVEL` | `INFO` | Level of the `audit` logger. |
+| `AUDIT_LOG_STREAM` | `ext://sys.stdout` | Where the handler writes |
+| `AUDIT_LOG_SERVICE_NAME` | `meet` | `service.name` |
+| `NUM_PROXIES` | `1` | DRF's number of trusted proxies appending to `X-Forwarded-For`, shared with the throttles. The client is the entry that many positions from the right; anything a client injects lands further left and is ignored. `1` matches ingress-nginx defaults; use `2` behind a load balancer that also appends |
+| `REQUEST_ID_TRUST_HEADER` | `False` | Reuse the inbound request id as `trace.id`, so the ingress, Gunicorn, application logs and audit events share one id. Only set it when the ingress overwrites the header (`proxy_set_header X-Request-ID $request_id;` on ingress-nginx, which otherwise forwards the client's one): a client could else pick the id of someone else's request |
+| `DOCKERFLOW_REQUEST_ID_HEADER_NAME` | `X-Request-ID` | Header carrying that id: read on the request only when `REQUEST_ID_TRUST_HEADER` is set, always echoed on the response |
+
+The project describes itself to the facility in code, from `core/auditing.py`. The audit app imports the `auditing`
+module of every installed app once it is ready:
+
+- `audit.register(Model, fields=..., admin_values=..., category=...)`: the `fields` describing a model as a target,
+  the `admin_values` whose before and after values may be recorded in the admin, and the `category` of its admin
+  writes. A proxy model falls back to its concrete model. Registering a model twice raises `AlreadyRegistered`.
+- `audit.register_auth_method(klass, name)`: the `lasuite.auth.method` of a DRF authentication class or of a login
+  backend. A DRF class inherits the name of its closest registered base, and DRF's own classes are built in. A login
+  backend must be registered itself, as custom backends often subclass `ModelBackend` for its permission checks
+  alone; `ModelBackend` is built in as `password`.
+
+The `audit` logger does not propagate and is ignored by Sentry. Application logs keep their text format; only the audit stream is JSON.

 ## Tuning recording encoding
 
-By default, LiveKit Egress records with the built-in `H264_720P_30` preset: 1280×720 at 30 fps, 3000 kbps H.264 MAIN video and 128 kbps AAC audio. For a one-hour meeting this produces a file of roughly **1.4 GB**, which is often heavier than necessary for talking-head content and screen sharing.
+Every video recording is encoded from a default resolved from `RECORDING_ENCODING_DEFAULT_PROFILE` + `RECORDING_ENCODING_DEFAULT_RESOLUTION` and passed to LiveKit as advanced `EncodingOptions`. The shipped defaults (`full` profile) match LiveKit's built-in `H264_720P_30` preset. For a one-hour meeting that produces a file of roughly **1.4 GB**, which is often heavier than necessary for talking-head content and screen sharing; lowering the default profile/resolution shrinks it. If either default is left unset, no custom default encoding is built: a warning is logged at startup and LiveKit's built-in preset is used instead.
 
-The `RECORDING_ENCODING_*` settings let operators override this preset without modifying the source. Values are passed straight through LiveKit's `EncodingOptions.advanced` to the GStreamer pipeline (`x264enc` for video, `faac` for audio), so there are no hidden conversions — what you set is what the encoder receives.
+Encoding is chosen from two maps: `RECORDING_ENCODING_AVAILABLE_RESOLUTIONS` (`resolution → {"width", "height"}`) and `RECORDING_ENCODING_AVAILABLE_PROFILES` (`profile → {"fps", "kbps": {resolution: video_bitrate_kbps}}`):
+
+- **Default**: `RECORDING_ENCODING_DEFAULT_PROFILE` + `RECORDING_ENCODING_DEFAULT_RESOLUTION` set the encoding used by every recording that doesn't override it. Leave either unset to fall back to LiveKit's built-in preset (a startup warning is emitted).
+- **Per recording (opt-in)**: set `RECORDING_CUSTOM_ENCODING_ENABLED=True` to let clients override the default per recording. The start-recording API then accepts an `encoding` object selecting a `resolution` (required) and `profile` (optional): a resolution-only request keeps `RECORDING_ENCODING_DEFAULT_PROFILE` for fps and bitrate, so clients can only pick from pre-defined values. When `RECORDING_CUSTOM_ENCODING_ENABLED=False`, the API rejects any per-recording `encoding` and the default is used.
+
+The resolved values are passed straight through LiveKit's `EncodingOptions.advanced` to the GStreamer pipeline (`x264enc` for video, `faac` for audio), so there are no hidden conversions — what the profile/resolution resolve to is what the encoder receives.

 The H.264 profile is fixed to MAIN and the x264 `speed-preset` to `veryfast` by LiveKit (real-time constraint) — lowering the framerate is therefore the main lever to save CPU, while lowering the bitrate is the main lever to shrink the output file.
 
-### Reference profiles
+### Built-in profiles
 
-Rough 30-minute file-size estimates assume video + audio bitrate multiplied by duration. Actual sizes vary with content (static talking heads compress better than heavy screen motion). Egress CPU figures are indicative, measured on a single Ryzen laptop core saturated by the default preset (= 100 %); scaling is roughly linear with `framerate × bitrate` but the absolute numbers depend on the host hardware.
+The default `RECORDING_ENCODING_AVAILABLE_PROFILES` ship four profiles. Framerate is fixed per profile; video bitrate (kbps) scales with resolution so quality stays consistent across sizes. File size scales roughly with `framerate × bitrate`, and so does egress CPU cost.

+To pick a profile per recording (requires `RECORDING_CUSTOM_ENCODING_ENABLED=True`), the client sends it in the start-recording request:

+```json
+{
+  "mode": "screen_recording",
+  "options": {"encoding": {"resolution": "720p", "profile": "talking_heads"}}
+}
+```
+
+To change the default encoding applied to every recording:
 
 ```bash
-RECORDING_ENCODING_ENABLED=True
-RECORDING_ENCODING_WIDTH=1280
-RECORDING_ENCODING_HEIGHT=720
-RECORDING_ENCODING_FRAMERATE=15
-RECORDING_ENCODING_VIDEO_BITRATE_KBPS=600

 ### Caveats
 
-- **Screen-share readability — think bits/frame, not bitrate**: at 720p, text legibility starts to break down below ~40 kbits/frame (= `bitrate ÷ framerate`). The recommended preset (600 kbps × 15 fps) sits at exactly that threshold, comfortable for talking heads with occasional slide sharing. The same 600 kbps at 30 fps would only deliver 20 kbits/frame and visibly blur dense slides — which is why **lowering framerate is a more screen-share-friendly lever than lowering bitrate**. For deck-heavy or IDE-share meetings, prefer the **Slide-heavy** profile (900 kbps × 15 fps ≈ 60 kbits/frame).
+- **Screen-share readability — think bits/frame, not bitrate**: at 720p, text legibility starts to break down below ~40 kbits/frame (= `bitrate ÷ framerate`). The `talking_heads` profile (700 kbps × 15 fps) sits just above that threshold, comfortable for talking heads with occasional slide sharing. The same bitrate at 30 fps would only deliver ~23 kbits/frame and visibly blur dense slides — which is why **lowering framerate is a more screen-share-friendly lever than lowering bitrate**. For deck-heavy or IDE-share meetings, prefer the **`text`** profile (1000 kbps × 15 fps ≈ 67 kbits/frame).
 - **Motion handling**: the `veryfast` x264 preset is set by LiveKit and cannot be overridden here. Low-bitrate settings will therefore show more artefacts on fast motion than an offline re-encode with a slower preset would. This is the other reason FPS reduction is the safer tuning lever for meeting recordings.
 - **Audio**: AAC at 64 kbps stereo is transparent for voice but starts to compress music noticeably. Keep 128 kbps if you expect music playback in meetings.
 - **Codec choice**: H.264 MAIN is hardcoded on purpose. Switching to HEVC or VP9 would increase egress CPU cost 2×–5×, defeating the goal of this tuning.
