 ## [Unreleased]
 
+### Purging deleted rooms
+
+Deleting a room now only soft deletes it: it is hidden but keeps its slug and PIN code. The `purge_inactive_rooms` command also permanently deletes soft-deleted rooms. See [the room purge documentation](docs/features/room-purge.md).
+
+- Inactive soft-deleted rooms are purged along with the other inactive rooms: if `ROOM_INACTIVITY_DELETION_DAYS` is already set, nothing else is needed.
+- The new `ROOM_DELETED_RETENTION_DAYS` setting purges soft-deleted rooms that many days after their deletion, whether they are inactive or not. It is unset by default.
+- As for inactive rooms, a deleted room holding a saved recording its users may still access is kept until that recording expires.
+
+### Recording permission
+
+We've introduced the ability for any authenticated participant to start a recording or transcription, but this behavior remains configurable.
+You can keep recording and transcription restricted to room admins and owners by setting `RECORDING_AUTHENTICATED_PARTICIPANTS_ENABLED` to `false`.
+
+## [v1.34.0]
+
+### Marketing / Brevo integration now uses `django-lasuite`
+
+The in-house marketing service (`core.services.marketing`) has been removed and
+replaced by the shared implementation from `django-lasuite`
+(`lasuite.marketing`). This fixes a bug where updating a user's contact on
+Brevo overwrote their list memberships, removing lists set by other
+La Suite products. Existing lists are now preserved and merged.
+
+**Celery worker required.** Newsletter signup on login
+(`SIGNUP_NEW_USER_TO_MARKETING_EMAIL=True`) is now dispatched as an
+asynchronous Celery task (`lasuite.marketing.tasks.create_or_update_contact`)
+instead of a synchronous call with a 1s timeout. Make sure a Celery worker is
+running alongside the backend, otherwise contacts will never be pushed to Brevo.
+
+**Configuration changes.** The following environment variables / settings are
+**removed** and no longer read:
+
+- `MARKETING_SERVICE_CLASS`
+- `BREVO_API_KEY`
+- `BREVO_API_CONTACT_LIST_IDS`
+- `BREVO_API_CONTACT_ATTRIBUTES` (previous default: `{"VISIO_USER": True}`)
+- `BREVO_API_TIMEOUT`
+
+They are replaced by a single `LASUITE_MARKETING` setting, configured through:
+
+| Variable                       | Default                                          | Description                                  |
+| ------------------------------ | ------------------------------------------------ | -------------------------------------------- |
+| `LASUITE_MARKETING_BACKEND`    | `lasuite.marketing.backends.dummy.DummyBackend`  | Backend class path                           |
+| `LASUITE_MARKETING_PARAMETERS` | `{}`                                             | Keyword arguments passed to the backend      |
+
+⚠️ The default backend is now a **dummy** (no-op). If you previously used
+Brevo, you must explicitly configure it, otherwise signups are silently dropped:

+    LASUITE_MARKETING_BACKEND=lasuite.marketing.backends.brevo.BrevoBackend
+    LASUITE_MARKETING_PARAMETERS={"api_key": "<your-brevo-api-key>", "api_contact_list_ids": [1, 2], "api_contact_attributes": {"VISIO_USER": True}}
+
+Migration mapping:
+
+- `BREVO_API_KEY` → `api_key`
+- `BREVO_API_CONTACT_LIST_IDS` → `api_contact_list_ids`
+- `BREVO_API_CONTACT_ATTRIBUTES` → `api_contact_attributes` (re-add
+  `{"VISIO_USER": True}` if you relied on the old default)
+- `BREVO_API_TIMEOUT` → no equivalent (the request runs in a background task)
+
+Note: `BREVO_API_KEY` used to support being read from a secret file; the API key
+now lives inside `LASUITE_MARKETING_PARAMETERS`, so adapt how you inject that
+secret (e.g. build the whole variable from your secret store).
+
+### 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.
+
+## v1.33.0
+
+### Purging inactive rooms
+
+Rooms now keep track of the last time they were started (`last_started_at`), fed by LiveKit's `room_started` webhook. A new `purge_inactive_rooms` management command permanently deletes the rooms that have not been started for `ROOM_INACTIVITY_DELETION_DAYS` days. See [the room purge documentation](docs/features/room-purge.md).
+
+- The feature is **disabled by default**: nothing is deleted unless you set `ROOM_INACTIVITY_DELETION_DAYS`.
+- The migration marks every existing room as started at the time of the upgrade, so no existing room can be purged before a full inactivity period has elapsed after upgrading.
+- Rooms holding a saved recording their users may still access are kept: any saved recording, or, when `RECORDING_EXPIRATION_DAYS` is set, a saved recording created within that window.
+- Inactivity is measured from LiveKit's `room_started` webhook: if it is not delivered to your backend, rooms in daily use look inactive and get purged.
+- When a room is purged, all it's configuration and access rights are also deleted. Its slug becomes available again and can be reused when a meeting is created from that same URL.
+
+* With `ALLOW_UNREGISTERED_ROOMS=false`, only an authenticated user can navigate to a previously existing link after the room has been purged. Doing so recreates the room in the database with a fresh configuration, with that user associated with it and granted admin rights.
+* With `ALLOW_UNREGISTERED_ROOMS=true`, any user can reopen the purged room by navigating to the same URL. In that case, the room is created dynamically and no corresponding room entry is persisted in the database.
+
+### Local development: MinIO replaced by Garage
+
+The development stacks now use [Garage](https://garagehq.deuxfleurs.fr/) instead of MinIO as S3 storage. Garage keeps its own format in `data/media/meta` and `data/media/data` and cannot read what MinIO left there, so local recordings and files will be lost.
+
+To migrate a local environment:
+
+1. Stop the stack and remove its containers, including the former `minio` one: `docker compose down --remove-orphans`
+2. Optionally reclaim the space used by MinIO: `rm -rf data/media && make data/media`
+3. In your `env.d/development/*` files, replace `minio:9000` by `garage:9000`, the `meet` / `password` credentials by `meet-access-key` / `meet-secret-access-key`, and add `AWS_S3_REGION_NAME=local` (or delete these files and run `make create-env-files`)
+4. Run `make create-env-files` to generate `env.d/development/garage`, which holds a random RPC secret for Garage.
+5. Rebuild the images, since the summary and agent images now install boto3 instead of minio
+
+### Summary service and metadata collector: boto3 replaces the minio client
+
+The summary service and the metadata collector agent now talk to S3 through boto3 instead of the minio client, with the same settings.
+Requests are now signed for `AWS_S3_REGION_NAME` as-is. When it is not set, the region is no longer looked up from the bucket: boto3 falls back to `AWS_DEFAULT_REGION`. If you left `AWS_S3_REGION_NAME` unset, set it to your provider's region before upgrading, or providers that check the signing region will reject the transcripts, summaries and meeting metadata uploads, as well as their signed URLs.
+
+Also:
+- Signed URLs to transcripts and summaries are now always path-style (`<endpoint>/<bucket>/<key>`), whereas the minio client used virtual-hosted-style URLs
+- The metadata collector now accepts `AWS_S3_ENDPOINT_URL` with or without a scheme, like the summary service: the scheme always follows `AWS_S3_SECURE_ACCESS`.
+
+### 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`.

+# Audit logging
+
+La Suite Meet keeps an **audit log**: a record of the notable things that happen in the product, such as a room created
+through the external API, a recording started, a sign-in, or a change made in the Django admin. Every entry answers the
+same questions: *who* did *what*, *to what*, *on whose behalf*, *from where*, and *did it work?*
+
+It is written for:
+
+- **operators and security teams** investigating an incident or watching for abuse
+- **data protection officers**, who need to know who accessed or changed what
+- **developers** adding a new audited action (see [For developers](#for-developers-emitting-events))
+
+Each event is a single line of JSON written to standard output, kept apart from the application logs.
+Events follow the [Elastic Common Schema](https://www.elastic.co/docs/reference/ecs)
+(ECS) 9.5.0, which most SIEMs understand out of the box.
+
+Personal data is kept to a minimum. A person is identified by their account id, their OIDC `sub` and the domain of their
+email address. Secrets, transit codes and the messages of unexpected exceptions are never recorded.
+
+## What an event looks like
+
+Events are written on the dedicated `audit` logger, one per line. Pretty-printed, one looks like this:
+
+```json
+{
+  "@timestamp": "2026-09-15T08:41:12.345+00:00",
+  "ecs": {"version": "9.5.0"},
+  "data_stream": {"type": "logs", "dataset": "meet.audit", "namespace": "default"},
+  "service": {"name": "meet", "environment": "production", "version": "1.34.0", "node": {"name": "meet-backend-6d8f7b9c4-x2x7q"}},
+  "event": {
+    "kind": "event",
+    "id": "0b3f6a0e-5d1c-4f43-9a8e-2b7c1d0e4f5a",
+    "action": "room.create",
+    "category": ["api"],
+    "type": ["creation"],
+    "outcome": "success",
+    "dataset": "meet.audit"
+  },
+  "client": {"ip": "1.2.3.4"},
+  "source": {"ip": "1.2.3.4"},
+  "http": {"request": {"id": "6f1c0d0e-2a8b-4c1d-9e7f-0a1b2c3d4e5f", "method": "POST"}, "response": {"status_code": 201}},
+  "url": {"path": "/external-api/v1.0/rooms/"},
+  "user_agent": {"original": "calendar-app/2.3"},
+  "user": {"id": "beecd833-4be4-4675-b139-a196b07144a9", "domain": "gouv.fr"},
+  "organization": {"id": "calendar-app"},
+  "entity": {
+    "target": {
+      "id": "9ae54744-ae64-44f4-b094-71e137556b66",
+      "sub_type": "room",
+      "name": "Daily standup",
+      "raw": {"slug": "daily-standup", "access_level": "trusted"}
+    }
+  },
+  "lasuite": {
+    "actor": {"type": "application", "sub": "0edebfa3-1355-4891-ae63-daf9fd37ac04"},
+    "auth": {"method": "application_jwt"},
+    "application": {"client_id": "calendar-app"},
+    "outcome": "success"
+  },
+  "log": {"level": "info", "logger": "audit"}
+}
+```
+
+Read it as: *the application `calendar-app`, acting on behalf of a user from `gouv.fr`, created the room "Daily standup"
+from `1.2.3.4`, and it worked.*
+
+When an action is refused, the event keeps the name of the action that was attempted, here still `room.create`. Only
+the fields describing the outcome change:
+
+```json
+{
+  "event": {"action": "room.create", "outcome": "failure", "type": ["creation", "denied"], "reason": "permission_denied"},
+  "lasuite": {"outcome": "denied"},
+  "http": {"response": {"status_code": 403}},
+  "error": {"message": "..."},
+  "log": {"level": "warning", "logger": "audit"}
+}
+```
+
+## Key concepts
+
+These words are used throughout this page and in the code (`core/audit/`). The *In the event* column says where to
+find each one in the JSON above.
+
+### The record
+
+| Term | Meaning | In the event |
+|---|---|---|
+| **Audit Event** | One immutable record that a notable action was attempted, by whom, on what, and with what outcome. Written as a single JSON line on the Audit Log. | The whole document, identified by `event.id` |
+| **Audit Log** | The stream of Audit Events. It is distinct from the application logs: a logger and a dataset of its own. | `data_stream.*`, `event.dataset` |
+| **Action** | The dotted, stable name of what was attempted, such as `room.create` or `application.token.issue`. It names the attempt, not its result: a refused `room.create` is still a `room.create`. Every Action belongs to the Catalogue. | `event.action` |
+| **Catalogue** | The closed list of Actions the code may emit, with their meaning and fields: see [Catalogue](#catalogue). Writes made through the Django admin are its one templated family, `admin.<target>.<verb>`. | — |
+| **Details** | The fields specific to one Action, such as the scopes granted with a token or the fields a room update changed. The Catalogue lists them. | `lasuite.details.*` |
+
+### Who acted
+
+| Term | Meaning | In the event |
+|---|---|---|
+| **Actor** | Who is behind an Action. It always has an Actor Type. When a person's account is involved, the event also carries the account id, its OIDC `sub` when it has one, and its email domain. | `lasuite.actor.*`, `user.*` |
+| **Actor Type** | What kind of Actor it is: `user`, `application`, `service`, `system` or `anonymous`. See [Actors](#actors). Device accounts are `user`s like any other account. | `lasuite.actor.type` |
+| **Auth Method** | How the Actor proved who it is for this request: `session`, `oidc`, `password`, `application_jwt`, `client_credentials`, `addons_jwt`, `user_access_jwt`, `transit_code`, `resource_server`, `menshen_token`, `livekit_token`, `shared_secret`, `none` when it did not authenticate, or `unknown`. | `lasuite.auth.method` |
+| **Application** | A registered third-party integration, identified by its client id, that calls the external API on behalf of users. | `lasuite.application.client_id` |
+| **Delegation** | An Application acting for one specific user, through the delegated token it obtained with `application.token.issue`. The event then names both: the Application as the Actor, and the user in `user.*`. | `lasuite.actor.type` = `application`, with `user.*` set |
+| **Provisional User** | An account an Application created from an email address before that person ever signed in. It has no OIDC `sub` yet, so its account id is what links its `user.provision` event to its later `user.login`. | `event.action` = `user.provision` |
+| **Machine User** | The identity of an internal service calling the backend with a shared secret: the LiveKit SIP bridge (`roomkit`), the summary service (`summary`), and the LiveKit server reporting that a recording ended (`livekit`). It is an Actor of type `service`, never an account. | `service.origin.name` |
+| **Tenant** | The organisation an event belongs to: the calling Application when there is one, otherwise the Actor's email domain. | `organization.id` |
+
+### What it was done to
+
+| Term | Meaning | In the event |
+|---|---|---|
+| **Target** | The resource the Action was attempted on: a room, a recording, an access grant, an application, a user or a transit code. Described by its type, its id and a few stable fields. See [Targets](#targets). | `entity.target.*` |
+| **User Target** | The person the Action was *about*, when there is one: a provisioned user, the user an access grants a role to, the account an admin edits, or the user a transit code is minted for. Not to be confused with `user.*`, the account whose authority was used. | `user.target.*` |
+
+### How it went
+
+| Term | Meaning | In the event |
+|---|---|---|
+| **Outcome** | Whether the Action succeeded (`success`), failed (`failure`), was refused (`denied`), or ended in a way the backend could not interpret (`unknown`). ECS has no `denied`: in `event.outcome`, a refusal is a `failure`. | `lasuite.outcome`, `event.outcome` |
+| **Reason** | Why an Action did not succeed, from a closed list: `authentication_failed`, `permission_denied`, `rate_limited`, `validation_error`, `not_found`, `conflict`, `internal_error`. | `event.reason` |
+| **Refusal** | An Action the backend would not let happen, such as a 401, 403 or 429. It is recorded under the Action that was attempted, with Outcome `denied`, never as an Action of its own. | `lasuite.outcome` = `denied` |
+
+### Where and when
+
+| Term | Meaning | In the event |
+|---|---|---|
+| **Source** | Where the request came from: the real client IP (never a proxy's), the HTTP method, the URL path and the user agent. Empty when no request is behind the event. | `client.ip`, `source.ip`, `http.request.method`, `url.path`, `user_agent.original` |
+| **Request Id** | The id shared by the Audit Events and the web server access log of one HTTP request, what other tools call a trace id. The backend generates it, unless the ingress is trusted to set it. | `http.request.id` |
+| **Emitter** | The backend instance that wrote the event: its name, environment, release and host (the pod, on Kubernetes). Never the caller. | `service.name`, `service.environment`, `service.version`, `service.node.name` |
+| **Peer Service** | Another service of the deployment taking part in the Action: the one that called the backend, or the one the backend called. | `service.origin.name`, `service.target.name` |
+
+### Where events go
+
+| Term | Meaning | In the event |
+|---|---|---|
+| **Sink** | Where Audit Events are written: the `audit` logger, whose handler writes to `AUDIT_LOG_STREAM`, standard output by default. A log shipper takes them from there. | `log.logger` = `audit` |
+| **Data Stream** | The data stream events are meant for, `logs-meet.audit-default` by default. It is what lets a shipper route audit events away from the application logs. | `data_stream.*` |
+
+### Embedded frontends
+
+| Term | Meaning | In the event |
+|---|---|---|
+| **Transit Code** | A single-use, short-lived code an Application mints for its delegated user and hands to an embedded frontend, which exchanges it for a User Access Token. Only its SHA-256 is ever logged. | `entity.target.sub_type` = `transit_code` |
+| **User Access Token** | The token an embedded frontend uses to call the API as the user, where session cookies are blocked (in an iframe, for example). Requests made with it are recorded as the Application acting for that user. | `lasuite.auth.method` = `user_access_jwt` |
+
+## Answering common questions
+
+These are the fields to filter on for the questions that come up most. They work the same whatever tool you search
+your logs with.
+
+**Who created, changed or deleted this room?**
+Filter on `entity.target.sub_type: room` with the room's id in `entity.target.id`, or its slug in
+`entity.target.raw.slug`. `event.action` says what happened, and `user.id` or `lasuite.application.client_id` who did
+it. Rooms are audited when they are handled through the external API (`room.*`) or the Django admin (`admin.room.*`).
+
+**What has this application done?**
+Filter on `lasuite.application.client_id`. To include the attempts made before its credentials were verified, such as a
+wrong secret or an inactive application, also search `lasuite.details.claimed_client_id`.
+
+**What did this person do, and what was done to their account?**
+`user.id` is the account whose authority an action used, and `user.target.id` the account an action was about: search
+both. To follow someone across the other La Suite products, use their OIDC `sub`, in `lasuite.actor.sub`.
+
+**Which requests were refused, and why?**
+Filter on `lasuite.outcome: denied` and group by `event.reason`. A burst of `authentication_failed` on `user.login` or
+`application.token.issue` from a single `source.ip` deserves a closer look.
+
+**What else happened during this request?**
+Take its `http.request.id`. The same id is sent back in the `X-Request-ID` response header, and appears on every audit
+event of the request and in the Gunicorn access log as `rid=`. The application logs do not carry it. A single request
+may produce several events: an application obtaining a token for someone who never signed in produces both
+`user.provision` and `application.token.issue`.
+
+## Fields reference
+
+Events follow the [Elastic Common Schema](https://www.elastic.co/docs/reference/ecs) 9.5.0. Only two namespaces hold
+what ECS does not define: `lasuite.*`, and `entity.target.raw.*` for the fields of a target.
+
+| Field | Meaning |
+|---|---|
+| `@timestamp` | When the event was emitted: ISO 8601, in UTC, with millisecond precision |
+| `data_stream.*`, `event.dataset` | `logs`, `<AUDIT_LOG_SERVICE_NAME>.audit` and `AUDIT_LOG_DATA_STREAM_NAMESPACE`: what sets the audit stream apart from the application logs |
+| `service.name`, `service.environment`, `service.version`, `service.node.name` | The Emitter: `AUDIT_LOG_SERVICE_NAME`, the current environment, the release and the host name (the pod, on Kubernetes). Never the caller |
+| `service.origin.name` | The internal service that called the backend, when the actor is a `service`: `roomkit`, `summary` or `livekit` |
+| `service.target.name` | The service the backend called, such as `summary` for `recording.transcript.request` |
+| `event.id` | Unique id of the event, so that a shipper retrying it cannot create a duplicate |
+| `event.action` | What was attempted, from the [Catalogue](#catalogue) |
+| `event.category`, `event.type` | The ECS classification (`api`, `authentication`, `iam`... and `creation`, `change`, `access`, `denied`, `user`...). Always a combination ECS expects, see [Classification](#classification) |
+| `event.outcome` | ECS `success` or `failure` (refusals included), or `unknown` when the result was reported in terms the backend does not recognise |
+| `event.reason` | Why it did not succeed: `authentication_failed`, `permission_denied`, `rate_limited`, `validation_error`, `not_found`, `conflict`, `internal_error` |
+| `lasuite.outcome` | `success`, `failure`, `denied` or `unknown`: the same as `event.outcome`, with refusals kept apart |
+| `lasuite.actor.type` | `user`, `application`, `service`, `system` or `anonymous`, see [Actors](#actors) |
+| `lasuite.actor.sub` | The OIDC `sub` of the account in `user.*`, when it has one: the identity it shares with the other La Suite products |
+| `lasuite.auth.method` | `session`, `application_jwt`, `addons_jwt`, `user_access_jwt`, `resource_server`, `menshen_token`, `livekit_token`, `shared_secret`, `client_credentials`, `transit_code`, `oidc`, `password`, `none`, or `unknown` for an authentication class that is not registered. Requests served outside DRF, such as the admin and logout, report `session` when signed in |
+| `lasuite.application.client_id` | The external application acting, if any. Only set once its credentials are verified. For a Menshen token, Menshen's own client id (see [Actors](#actors)) |
+| `user.id`, `user.domain` | The account whose authority the action used (see [Actors](#actors)): its primary key and email domain. The email address itself is never recorded |
+| `user.roles` | That account's privileges when the event happened: `superuser`, `staff` |
+| `user.target.id`, `user.target.domain` | The account the action was about: the target when it is a user, or the user an access grants a role to. `user.*` stays the actor |
+| `organization.id` | The Tenant: the application's client id when there is one, otherwise the user's email domain |
+| `entity.target.*` | The resource acted on, see [Targets](#targets) |
+| `lasuite.details` | Fields specific to the action, see the [Catalogue](#catalogue) |
+| `client.ip`, `source.ip` | The real client address, the same one DRF's throttles identify (see `NUM_PROXIES`) |
+| `http.request.method`, `url.path` | The request as received |
+| `user_agent.original` | The client's `User-Agent`, cut at 1024 characters |
+| `http.request.id` | The Request Id. Also sent back as the `X-Request-ID` response header and logged by Gunicorn as `rid=`. Generated by the backend unless `REQUEST_ID_TRUST_HEADER` is set |
+| `http.response.status_code` | The status of the response, for API calls and refusals |
+| `error.message` | A human-readable reason for a failure |
+| `error.type` | The class of an unhandled exception. Its message is left out, as it may contain personal data |
+| `log.level` | `info` for a success, `warning` for failures, refusals and unknown outcomes, `error` for internal errors |
+
+### Targets
+
+The resource an action was performed on is described with ECS `entity.target`, the field set ECS 9.3 introduced for
+"the targeted entity of an action taken". ECS still flags the `entity` fields as beta.
+
+| Field | Meaning |
+|---|---|
+| `entity.target.id` | Its primary key |
+| `entity.target.sub_type` | Its model: `room`, `recording`, `user`, `application`, `resourceaccess` or `transit_code` (identified by its SHA-256) |
+| `entity.target.type` | Its ECS entity type, when one fits: `user` for an account, `application` for an application |
+| `entity.target.name` | Its name, when its model registers one |
+| `entity.target.raw.*` | The other fields its model registers, such as a room's `slug` and `access_level`, or the OIDC `sub` of a user |
+
+### Actors
+
+`lasuite.actor.type` says *who* acted, and `user.*` *whose authority* the action used. They are not always the same: when
+an application acts for a user, the actor is the application, but `user.*` is that user.
+
+| `lasuite.actor.type` | Who | `user.*` |
+|---|---|---|
+| `user` | A person's account acting for itself: through a session, an OIDC or password login, an add-on token, or the LiveKit token of a known account | That account |
+| `application` | A client application acting on behalf of a user. Either a Meet application, through its client credentials, its delegated token or the user access token of its embedded frontend, or another La Suite application, through the resource server or a token exchanged with Menshen. `lasuite.application.client_id` names it | The delegating user |
+| `service` | An internal service of the deployment, named by `service.origin.name`: the LiveKit SIP bridge (`roomkit`), the summary service (`summary`), or the LiveKit server reporting on a recording (`livekit`) | Absent |
+| `system` | The backend itself, with no inbound request | Absent |
+| `anonymous` | A caller that did not authenticate, or failed to | Absent |
+
+The backend picks the actor type by applying these rules in order:
+
+1. A client id is known, usually from the token payload: `application`.
+2. There is neither a request nor an actor: `system`.
+3. The caller authenticated without an account, as a Machine User: `service`.
+4. The caller is an account: `user`.
+5. Anything else: `anonymous`.
+
+A La Suite application calling the external API with a token it exchanged through Menshen, La Suite's token exchange
+server, is recorded as an `application`, with `lasuite.auth.method` `menshen_token`. Menshen reports itself as the client
+the token was issued to, not the application that exchanged it, so `lasuite.application.client_id` and `organization.id`
+are Menshen's client id for every such call. The token is never recorded, nor its `jti`, which for an opaque token
+Menshen takes from the token itself, nor the email Menshen reports.
+
+### Classification
+
+`event.category` and `event.type` are only ever combined in the ways the ECS 9.5.0 `expected_event_types` allow:
+
+- Each action declares its category, `api` by default, and its types. A type its category does not expect fails at
+  import time, so a misclassified action can't ship.
+- A refusal adds the `denied` type only when the category expects it. An API call becomes `["creation", "denied"]`. A
+  failed login stays `["start"]`, and `event.outcome`, `event.reason` and `lasuite.outcome` show that it was refused.
+- A 401 is also filed under `authentication`, as in `["api", "authentication"]`, so that it counts as a failed
+  authentication.
+
+When an audited API action raises an exception DRF does not handle, the event is still recorded before the exception
+propagates: as a `failure` with reason `internal_error`, status code `500` and `error.type`.
+
+## Catalogue
+
+Action names are dotted and lower-case, in the form `<target>.<verb>`. They name what was *attempted*: whether it worked
+is told by `event.outcome`, `lasuite.outcome` and `event.reason`, never by the name.
+
+### Applications and delegation
+
+| `event.action` | Emitted when | Notable fields |
+|---|---|---|
+| `application.token.issue` | An application asks for a delegated token (`POST /external-api/v1.0/application/token/`), whether it gets one or is refused. It can be refused for bad credentials, an inactive application, an invalid or unauthorized email domain, an unknown user, or a provisioning conflict | On success: `user.*` is the delegated user, `entity.target` the application, and `lasuite.details` holds `scopes`, `user_provisioned` and `expires_in`. On refusal: `event.reason`, `http.response.status_code` and `lasuite.details.requested_domain`. Until its credentials are verified, the client id the caller submitted is only recorded as `lasuite.details.claimed_client_id`: it never sets `lasuite.application` or `organization` |
+| `user.provision` | An application creates a provisional user from an email address, or fails to. It is a `failure` with reason `conflict` when a concurrent request created the user first. Also emitted when a La Suite application calls the external API, through the resource server or with a Menshen token, for a `sub` no account has and `OIDC_CREATE_USER` lets the backend create one | `user.target` and `entity.target` are the user, the existing one on a conflict. `lasuite.auth.method` is `client_credentials`, `resource_server` or `menshen_token`. A provisional user has no `sub` yet: its id links this event to the winning one and to its later `user.login`. On a conflict over an email, `lasuite.details.requested_sub` is the `sub` no account was created for |
+| `transit_code.issue` | An application mints a single-use transit code for its delegated user | `entity.target` is the code, whose `id` is its SHA-256. `user.target` is the user it is minted for. `lasuite.details.expires_in` |
+| `transit_code.exchange` | An embedded frontend exchanges a transit code for a user access token | `event.category` is `authentication`, `lasuite.auth.method` is `transit_code`, and `entity.target` is the code's SHA-256. Once the code verifies, even if the exchange is then refused: `lasuite.actor.type` is `application` (the one that minted it), and `user.target` the user it was minted for. On success, `user.*` is that user too, with `lasuite.details.expires_in`. A code that does not verify is recorded as an `anonymous` failed authentication |
+
+### Rooms
+
+Rooms are audited on the external API only.
+
+| `event.action` | Emitted when | Notable fields |
+|---|---|---|
+| `room.create` | A room is created through the external API, or the attempt fails | `entity.target` is the room |
+| `room.update` | A room is updated through the external API, or the attempt fails | `entity.target` is the room, refusals included. `lasuite.details.updated_fields` and `previous_access_level` |
+| `room.delete` | A room is deleted through the external API: soft deleted, its LiveKit room closed. Or the attempt fails | `entity.target` is the room, refusals included |
+| `room.retrieve` | A room is read through the external API, or the attempt fails | `entity.target` is the room |
+| `room.list` | Rooms are listed through the external API, or the attempt fails | `lasuite.details.total` |
+
+### Recordings, transcripts and summaries
+
+| `event.action` | Emitted when | Notable fields |
+|---|---|---|
+| `recording.start` | A room owner or administrator starts a recording, or the attempt fails: a recording already in progress, a worker error | `entity.target` is the recording, or the room when none was created. `lasuite.details.collect_metadata` |
+| `recording.stop` | A room owner or administrator stops the recording in progress, or the attempt fails | `entity.target` is the recording, or the room when none is active |
+| `recording.end` | LiveKit reports that a recording ended (`egress_ended` webhook): `success` when its media file is available, `failure` when it was aborted or failed, `unknown` for a status the backend does not map | `service.origin.name` is `livekit`. `entity.target` is the recording as it was before the report was processed. `lasuite.details.worker_event` (`completed`, `limit reached`, `aborted`, `failed`) and `error_code` |
+| `recording.delete` | A recording is deleted, or the attempt fails | `entity.target` is the recording |
+| `recording.transcript.request` | The backend sends a recording to the summary service to be transcribed, or fails to | `lasuite.actor.type` is `system`, `service.target.name` is `summary`, and `entity.target` is the recording. `lasuite.details.summary_requested` (whether a summary of the transcript is to be made too) and `job_id` |
+| `recording.transcript.report` | The summary service reports on a transcript (`external-process-hook`), or a call to that hook is refused | `service.origin.name` is `summary`. `entity.target` is the recording, absent for an unknown job. `lasuite.details.job_id` and `status`. A failure the service reports is recorded as a `failure` |
+| `recording.summary.report` | The summary service reports on a summary | Same as `recording.transcript.report` |
+
+A recording's target says what was recorded:
+
+- `mode` is how the media was captured: `screen_recording` for a video, `transcript` for an audio track;
+- `requested_mode` is what the user asked for;
+- `is_transcribed` says whether it is sent to the summary service.
+
+`mode` and `requested_mode` differ for a transcript started with a screen capture: `mode` is then `screen_recording`,
+and `requested_mode` is `transcript`.
+
+Transcripts and summaries are not recordings, but what the summary service derives from one. They are audited under
+`recording.transcript.*` and `recording.summary.*`, with the recording as their target.
+
+### Sign-in and the admin
+
+| `event.action` | Emitted when | Notable fields |
+|---|---|---|
+| `user.login` | A user signs in, or a sign-in attempt fails: `denied`, with reason `authentication_failed` | `lasuite.auth.method` is `oidc`, `password` or `unknown`. On success, it is named after the login backend, also given in `lasuite.details.auth_backend`. On failure, it is named after the credentials submitted: a password, or the nonce of the OIDC callback |
+| `user.logout` | A user signs out | |
+| `admin.access` | A signed-in account without staff access reaches an admin page. Always denied, once per refused page | `event.category` is `web` and `event.type` is `access`. `event.reason`, and `http.response.status_code`: the redirect to the login page |
+| `admin.<target>.<verb>` | A write is made through the Django admin, see [Django admin](#django-admin) | |
+
+## Django admin
+
+The admin is the most sensitive part of the product, so every write made through it produces an audit event, alongside
+the `LogEntry` Django already writes. Nothing is replaced and there is no extra table: the admin history keeps working.
+
+The action name follows a template, `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`, and 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` |
+
+This gives names such as `admin.room.update`, `admin.user.delete` or `admin.recording.action`. `event.category` is `iam`
+for anything that grants access to the product, and `configuration` otherwise. Writes on a user or a group put `user` or
+`group` first in `event.type`, as in `["user", "change"]`.
+
+### What changed
+
+- `lasuite.details.changed_fields` always lists the **names** of the fields a form changed, exactly the ones Django
+  reports in its own history.
+- `lasuite.details.changes` gives their **values**, as `{"from": ..., "to": ...}`, but only for the fields a model
+  explicitly allows in the `admin_values` it is registered with (see
+  [Registering models](#registering-models-and-authentication-methods)).
+- Anything that looks like a secret is refused, whatever the allow-list says. A password change is reported as a change
+  to `password`, never with its value.
+- A `JSONField` on the allow-list, such as a room's `configuration`, is recorded as JSON rather than as a string, and
+  both versions are kept whole.
+
+### Inlines
+
+Objects edited through an **inline** produce their own event, linked to the parent's by `http.request.id`. Granting a
+role on a room produces both `admin.room.update` and `admin.resourceaccess.create`, whose `user.target` is the account
+granted the role.
+
+### What is 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.
+- **Custom actions that bypass the ORM hooks.** An action calling `queryset.update()` or `queryset.delete()` directly
+  is reported as a single `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` per object and no `action` event.
+
+### How it is wired
+
+The wiring lives in `core/audit/admin.py`. `AuditedAdminSite` adds auditing to every admin class when it is registered,
+including those Django declares 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
+[Registering models](#registering-models-and-authentication-methods)) only adds its category and its allowed values.
+
+## For developers: emitting events
+
+### Declaring an action
+
+Every action is declared once, in `core/auditing.py`, as an `audit.Action` constant. 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")
+```
+
+`core/auditing.py` imports nothing but the audit facility, so that any module can import it, authentication classes
+included. Models and authentication classes are registered apart, in `core/audit_registry.py`.
+
+### Auditing a DRF view
+
+A DRF view only declares the actions it audits: everything else is derived from the response. CRUD actions are mapped
+in `audit_actions`. 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): ...
+```
+
+`AuditViewMixin` fills in the rest:
+
+- It runs from DRF's `finalize_response` hook, which every response goes through, successful or not.
+- The ECS category and types come from the action, or default to `api` and the DRF action.
+- The outcome, reason and status code come from the response status: 401, 403 and 429 are `denied`, other errors are
+  `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_user_target`, `audit_actor` (`None` records no account) and `audit_details`, or override
+  `get_audit_fields()`.
+
+### Auditing from anywhere else
+
+Outside of `AuditViewMixin`, from a view or deeper in a service, call `audit.log`. A `category` or `types` given here
+wins over the action's:
+
+```python
+audit.log(auditing.USER_PROVISION, target=user)
+```
+
+Without `request=`, the event reads the context of the request being served, `audit.request_context()`, which
+`AuditLogMiddleware` captures when the request comes in. Outside a request, as in a Celery task, the context is empty
+and the actor is the system.
+
+> [!NOTE]
+> That context holds the Django request. DRF copies its user and auth onto it, but not its authenticator, so a call
+> made inside a DRF view without `request=` should pass `auth_method=`.
+
+### How fields are filled
+
+- **Request fields** are read from the request: the real client address, the path and the user agent.
+  `http.request.id` is the request id, settled by `AuditLogMiddleware` right after dockerflow assigns it, and echoed in
+  the `DOCKERFLOW_REQUEST_ID_HEADER_NAME` response header (`X-Request-ID` by default). The inbound id is only kept when
+  `REQUEST_ID_TRUST_HEADER` is set. Otherwise the backend generates one, so a client never picks it.
+- **The actor** is derived from `request.user`, `request.auth` and the DRF authenticator, as described in
+  [Actors](#actors). The authenticator's class is mapped to an auth method by `audit.register_auth_method` (see
+  [Configuration](#configuration)). Without a request, the actor is the system. You can override it with `actor=`,
+  `actor_type=`, `auth_method=` and `client_id=`. An explicit `actor_type=` keeps the account the request is signed in
+  as. `actor=None` records no account: for a caller failing to authenticate, an application acting before it is given
+  a delegated user, or the system.
+- **The target** is described by its model name, its primary key and the `fields` its model is registered with, see
+  [Targets](#targets). A model that is not registered is still identified. The account the action is about,
+  `user.target`, is found from the target, unless given as `user_target=`. Name a service the backend calls with
+  `target_service=`. Any other keyword argument lands under `lasuite.details`.
+
+### Emission never raises
+
+A broken configuration or value is reported on the application logger (and to Sentry), and the business operation goes
+on. 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`, and the dataset `<name>.audit`, with any `-` turned into `_` |
+| `AUDIT_LOG_DATA_STREAM_NAMESPACE` | `default` | `data_stream.namespace`: events are routed to the data stream `logs-meet.audit-<namespace>`. It must not contain `-` |
+| `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 the ingress-nginx defaults; use `2` behind a load balancer that also appends |
+| `REQUEST_ID_TRUST_HEADER` | `False` | Reuse the inbound request id as `http.request.id`, so that the ingress, Gunicorn 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): otherwise a client could pick the id of someone else's request |
+| `DOCKERFLOW_REQUEST_ID_HEADER_NAME` | `X-Request-ID` | The header carrying that id. Read on the request only when `REQUEST_ID_TRUST_HEADER` is set, always echoed on the response |
+
+### Registering models and authentication methods
+
+The project describes itself to the audit facility in code, in `core/audit_registry.py`. Once the audit app is ready,
+it imports the `audit_registry` module of every installed app.
+
+**`audit.register(Model, ...)`** tells the audit log how to handle a model:
+
+- `fields`: the fields describing it as a target;
+- `admin_values`: the fields whose before and after values may be recorded for admin writes;
+- `category`: the ECS category of its admin writes;
+- `entity_type`: its ECS entity type, when one of the allowed values fits (`application`, `user`...);
+- `user_target`: the attribute holding the account an event on it is about, such as `user` for an access.
+
+A proxy model falls back to its concrete model. Registering a model twice raises `AlreadyRegistered`, and an entity type
+ECS does not allow raises `ValueError`.
+
+**`audit.register_auth_method(klass, name)`** sets 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, because custom backends often subclass `ModelBackend` just for its permission
+checks. `ModelBackend` is built in as `password`.

 ## 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:
 
-Environment variables for the **Low CPU / small file** profile:
+```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.

+# Room purge
+
+Rooms pile up over time and most of them are only used once. The `purge_inactive_rooms` management command permanently deletes the rooms that have not been started for a configurable number of days, and the rooms deleted by their owner for longer than a configurable retention period. It is disabled by default.
+
+## How it works
+
+Each time LiveKit tells the backend that a room has started (`room_started` webhook), the backend records the date on the room (`last_started_at`).
+A room is inactive when:
+
+- it was last started more than `ROOM_INACTIVITY_DELETION_DAYS` days ago, or
+- it was never started and was created more than `ROOM_INACTIVITY_DELETION_DAYS` days ago.
+
+Rooms that existed before this feature was deployed are considered started on the day of the release, so none of them can be purged before a full inactivity period has elapsed.
+
+Deleting a room through the API only soft deletes it: the room is hidden, its link tells visitors the meeting was deleted, and it keeps its slug and PIN code. A soft-deleted room is purged:
+
+- when it is inactive, as described above: a deleted room is never considered started again, so its inactivity period keeps running, or
+- when it was deleted more than `ROOM_DELETED_RETENTION_DAYS` days ago.
+
+The command is meant to run once a day. The Helm chart schedules it in `backend.cronjobs` (`purge-inactive-rooms`, 01:00); it does nothing until `ROOM_INACTIVITY_DELETION_DAYS` or `ROOM_DELETED_RETENTION_DAYS` is set.
+
+```bash
+python manage.py purge_inactive_rooms            # delete the inactive and deleted rooms
+python manage.py purge_inactive_rooms --dry-run  # only list the rooms that would be deleted
+```
+
+## Rooms that are kept
+
+A recording can only be reached through its room. A room is kept, past its inactivity or retention period, as long as it holds a saved recording its users may still access:
+
+- with `RECORDING_EXPIRATION_DAYS` set, a saved recording created less than that many days ago,
+- with `RECORDING_EXPIRATION_DAYS` unset, any saved recording.
+
+## What happens to a purged room
+
+The room is deleted from the database, along with its accesses, its telephony PIN code, and the recording entries it still holds — the expired ones and those that were never saved, since any other recording would have protected the room — together with their own accesses.
+
+The recording **files in the bucket are left untouched**: the backend never deletes anything from the storage, it only drops the database entries pointing at it. Removing the files is the job of the bucket lifecycle policy, which should match `RECORDING_EXPIRATION_DAYS` (see the [recording documentation](recording.md)). When the two do not match, the purge leaves objects behind: they become unreachable, since serving a recording requires its database entry, but they keep costing storage.
+
+⚠️ When a room is purged, all it's configuration and access rights are also deleted. Its slug becomes available again
+and can be reused when a meeting is created from that same URL. This also applies to a soft-deleted room: once purged, its link
+no longer tells visitors the meeting was deleted, and its PIN code can be given to another room.
+
+* With `ALLOW_UNREGISTERED_ROOMS=false`, only an authenticated user can navigate to a previously existing link after the room has been purged. Doing so recreates the room in the database with a fresh configuration, with that user associated with it and granted admin rights.
+
+* With `ALLOW_UNREGISTERED_ROOMS=true`, any user can reopen the purged room by navigating to the same URL. In that case, the room is created dynamically and no corresponding room entry is persisted in the database.

+### Feature flags without an analytics backend
+
+Some features, such as automatic meeting summaries (`summary-enabled`), are gated by a feature flag read from the analytics backend. You do not need an analytics backend to enable them: leave `ANALYTICS_BACKEND` unset and declare the flags in `env.d/common`. No data is sent anywhere.
+
+```env
+ANALYTICS_BACKEND_SETTINGS={"feature_flags": {"summary-enabled": True}}
+```
+
+You can also set it directly in `compose.yaml`:
+
+```yaml
+services:
+  backend:
+    environment:
+      ANALYTICS_BACKEND_SETTINGS: '{"feature_flags": {"summary-enabled": True}}'

 ## Step 3: Configure your firewall
 
 If you are using a firewall as it is usually recommended in a production environment you will need to allow the webservice traffic on ports 80 and 443 but also to allow UDP traffic for the WebRTC service.
