⚡️(backend) send recording notification emails from a Celery task

Emails were rendered and sent inline in the LiveKit webhook, so a
slow SMTP server blocked the request and a transient failure lost
the email. Delivery now runs in a worker, with retries and backoff.

The task is generic (template, subject, recipients, context,
language) so other emails can reuse it. The subject is translated
in the worker, and dates are formatted per owner before queuing,
so the arguments stay JSON-serializable.

Without Celery, the task still runs synchronously. Success now
means "queued", not "delivered".

 ## [Unreleased]
 
+### 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`.

+### LiveKit agents (optional)

+The LiveKit agents are not started by `make run`. Each one runs its own
+container and stays connected to LiveKit, which costs CPU and memory you
+don't need unless you work on the features they power. Start them only
+when you need them.
+
+| Agent | Feature | Make command | Setting in `env.d/development/common` |
+|---|---|---|---|
+| `metadata-collector-dev` | Recording metadata (used to identify speakers in transcripts) | `make run-agent-metadata-collector` | `METADATA_COLLECTOR_ENABLED=True` |
+| `multi-user-transcriber-dev` | Live subtitles | `make run-agent-multi-user-transcriber` | `ROOM_SUBTITLE_ENABLED=True` |
+
+To start both at once:
+```shellscript
+$ make run-agents
+```
+
+Then set the matching settings to `True` and restart the backend so it
+picks them up:
+```shellscript
+$ make run-backend
+```
+
+The multi-user transcriber also needs a speech-to-text provider. Configure
+`STT_PROVIDER` and its credentials in
+`env.d/development/multi_user_transcriber`.
+
+Keep the settings and the agents in sync: if a setting is `True` while its
+agent is stopped, the backend still dispatches jobs to it and the feature
+fails silently.

 ## 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.
 
 ### How values map to GStreamer
 
-| Setting                               | GStreamer element | Property                           |
-| ------------------------------------- | ----------------- | ---------------------------------- |
-| `RECORDING_ENCODING_WIDTH/HEIGHT`     | capsfilter        | `video/x-raw,width=W,height=H`     |
-| `RECORDING_ENCODING_FRAMERATE`        | capsfilter        | `framerate=F/1`                    |
-| `RECORDING_ENCODING_VIDEO_BITRATE_KBPS` | `x264enc`       | `bitrate=kbps` (kilobits)          |
-| `RECORDING_ENCODING_KEY_FRAME_INTERVAL_S` | `x264enc`     | `key-int-max = interval × fps`     |
-| `RECORDING_ENCODING_AUDIO_BITRATE_KBPS` | `faac`          | `bitrate = kbps × 1000` (bits)     |
+| Resolved value                            | GStreamer element | Property                           |
+| ----------------------------------------- | ----------------- | ---------------------------------- |
+| resolution `width` / `height`             | capsfilter        | `video/x-raw,width=W,height=H`     |
+| profile `fps`                             | capsfilter        | `framerate=F/1`                    |
+| profile `kbps[resolution]`                | `x264enc`         | `bitrate=kbps` (kilobits)          |
+| `RECORDING_ENCODING_KEY_FRAME_INTERVAL_S` | `x264enc`         | `key-int-max = interval × fps`     |
+| `RECORDING_ENCODING_AUDIO_BITRATE_KBPS`   | `faac`            | `bitrate = kbps × 1000` (bits)     |
 
 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.

 ### 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. 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.
+
+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` is set.
+
+```bash
+python manage.py purge_inactive_rooms            # delete the inactive 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. An inactive room is kept 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.
+
+* 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.
