-## Contributing
+# Contributing

-We <3 contributions of any kind, big and small:
+We <3 contributions of all kinds **big or small** and we’re genuinely glad you’re here. 🌱

- Vote on features or get early access to beta functionality in our [roadmap](https://github.com/orgs/suitenumerique/projects/11/views/4)
- Open a PR (see our instructions on [developing La Suite Meet locally](https://github.com/suitenumerique/meet/blob/main/docs/developping_locally.md))
- Submit a [feature request](https://github.com/suitenumerique/meet/issues/new?assignees=&labels=enhancement&template=Feature_request.md) or [bug report](https://github.com/suitenumerique/meet/issues/new?assignees=&labels=bug&template=Bug_report.md)
+### Start by saying hi

+**The best first contribution is simply to come say hi.**
+
+Before opening a PR, especially a larger one, or one written with the help of AI, we encourage you to reach out to a maintainer on our [Matrix channel](https://matrix.to/#/#meet-official:matrix.org) (@antoine.lebaud:matrix.org).
+
+Getting in touch early helps us align on goals, avoid duplicated or wasted effort, and build a community that stays active, welcoming, and fun to be part of. There are no silly questions here: whether you’ve shipped hundreds of PRs or you’re just getting started, you’re welcome.
+
+### AI contributions
+
+AI-assisted contributions are welcome. But code is never the end goal. What matters most is building relationships, sharing knowledge, and growing a sustainable community over time.
+
+If your contribution has been heavily generated with AI, please be transparent about it. This helps maintainers review it with the right context and respects the time they invest in the project.
+
+Using AI does not transfer ownership of the contribution: you should still fully understand the code, the problem it solves, and the reasoning behind the approach you propose. In short, even if AI helped write it, the why should still be yours.
+
+### Contributions beyond code
+
+**Not technical? We need you too.**
+Open source is much more than code. Writing documentation, improving onboarding, translating content, answering questions, reporting bugs, or simply helping others feel welcome all make a huge difference.
+
+### Ways to contribute
+
+When you’re ready, here are a few ways to get involved:
+
+* 👋 **Say hello** and share your ideas with the community and maintainers on our [Matrix channel](https://matrix.to/#/#meet-official:matrix.org)
+* 🛠️ **Open a PR** by following our guide to [develop La Suite Meet locally](https://github.com/suitenumerique/meet/blob/main/docs/developping_locally.md)
+* 💡 **Suggest an idea** by opening a [feature request](https://github.com/suitenumerique/meet/issues/new?assignees=&labels=enhancement&template=Feature_request.md)
+* 🐛 **Report a bug** by opening a [bug report](https://github.com/suitenumerique/meet/issues/new?assignees=&labels=bug&template=Bug_report.md)
+
+Thank you for helping build something open, useful, and human. 💙
+
+### Community call
+
+We host a community call on the first Friday of every month to share updates, discuss ideas, and connect with contributors.
+
+Whether you’re actively contributing or just curious about the project, you’re welcome to join. More details are shared on the [Matrix channel](https://matrix.to/#/#meet-official:matrix.org).

 (Note : in your development environment, you can `make migrate`.)

 ## [Unreleased]
+
+## v1.23.0
+
+As part of the 1.23.0 release, the legacy `api/v1` implementation has been removed from the _experimental_ Summary service and Meet has been migrated to the new `api/v2`.
+
+**To avoid a breaking change, the Meet backend continues to use the Summary service's v1-compatible API format by default (`SUMMARY_SERVICE_VERSION` setting defaults to `1`).**
+
+If you are deploying both Meet and Summary from this repository, you must configure the Meet backend to use the v2 API by setting the following environment variable `SUMMARY_SERVICE_VERSION=2`.
+
+If you are upgrading only the Meet deployment while keeping an older Summary v1 compatible deployment, no action is required, as the v1-compatible API remains the default.
+
+Note that we plan on removing the legacy `v1` summary compatibility in a future major version. If you have your own implementation for the summary service, we recommend updating its API contract and setting `SUMMARY_SERVICE_VERSION=2`.

 This allows you to verify which recordings are in progress, troubleshoot egress issues, and confirm that recordings are being processed correctly.

+## 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.
+
+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.
+
+### 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)     |
+
+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
+
+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.
+
+| Profile                | Resolution | FPS | Video (kbps) | Audio (kbps) | Keyframe (s) | ~ size / 30 min | Egress CPU (vs. default) | Suitable for                                        |

+★ Recommended starting point for typical LaSuite Meet usage.
+
+Environment variables for the **Low CPU / small file** profile:
+
+```bash
+RECORDING_ENCODING_ENABLED=True
+RECORDING_ENCODING_WIDTH=1280
+RECORDING_ENCODING_HEIGHT=720
+RECORDING_ENCODING_FRAMERATE=15
+RECORDING_ENCODING_VIDEO_BITRATE_KBPS=600
+RECORDING_ENCODING_AUDIO_BITRATE_KBPS=64
+RECORDING_ENCODING_KEY_FRAME_INTERVAL_S=4.0
+```
+
+### 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).
+- **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.

+## Rebranding the favicon
+
+The favicon is bundled into the frontend image and served as a set of static
+files from `/usr/share/nginx/html` (`favicon.ico`, `favicon-16x16.png`,
+`favicon-32x32.png`, `apple-touch-icon.png`, `android-chrome-192x192.png`,
+`android-chrome-512x512.png`, `icon.png`). To rebrand without forking and
+rebuilding the image, overlay your own icons onto those paths with a volume —
+this serves the right icon from the first byte (no rebuild, no flash) and
+covers every variant, including the iOS home-screen and Android/PWA icons.
+
+Put your icons in a `ConfigMap` (`binaryData` keeps the PNGs intact)…
+
+```yaml
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: meet-favicon
+binaryData:
+  # base64 of each replacement icon
+  favicon.ico: <base64…>
+  favicon-16x16.png: <base64…>
+  favicon-32x32.png: <base64…>
+  apple-touch-icon.png: <base64…>
+  android-chrome-192x192.png: <base64…>
+  android-chrome-512x512.png: <base64…>
+```
+
+```bash
+# e.g. build the ConfigMap straight from a directory of icons
+$ kubectl create configmap meet-favicon --from-file=./my-icons/
+```
+
+…then mount each file over the bundled one via the chart's
+`frontend.extraVolumes` / `frontend.extraVolumeMounts` (the `subPath` mounts
+the single file without hiding the rest of `html/`):
+
+```yaml
+frontend:
+  extraVolumes:
+    - name: favicon
+      configMap:
+        name: meet-favicon
+  extraVolumeMounts:

+ *    cookie. No `csrfToken` argument needed — `getCsrfToken()` handles it.
+ *
+ * 2. Body-passed token: used by `poll`, called from the Office dialog /
+ *    taskpane iframe. Cookie access inside Office iframes is unreliable
+ *    across Outlook clients, so we can't depend on `document.cookie`
+ *    being populated. Instead, `init` returns the CSRF token in its JSON
+ *    response body, and callers pass it explicitly to subsequent calls.
+ *    The token still travels as `X-CSRFToken` — only its source differs.

+ * The `csrfToken` parameter takes precedence when provided; falls back

+    """ViewSet for managing add-on authentication sessions via token exchange.
+
+    Implements a three-step flow that lets a third-party add-on (running in an
+    embedded iframe) obtain an access token without exposing it to client-side
+    JavaScript:
+
+    1. /init: the add-on opens a session and receives a short-lived transit
+       token (used to bootstrap the OAuth-style exchange in a dialog) and a
+       CSRF token. The opaque session id is stored in an HttpOnly, Secure,
+       SameSite=None cookie so it can accompany cross-origin polls.
+    2. /poll: the add-on polls until the session transitions from pending to
+       authenticated. On the terminal read, the session payload (access
+       token, token type, expiry, etc.) is returned, the session is evicted
+       server-side, and the session cookie is cleared so the tokens can be
+       retrieved exactly once.
+    3. /exchange: called from the post-login callback page on our own domain,
+       after the user has authenticated in a dialog opened by the addon. The
+       transit token (carried client-side via postMessage + sessionStorage)
+       is redeemed here for the authenticated user's access token, which is
+       stored server-side against the session. Requires an authenticated
+       user — that user is whose access token gets bound to the session.
+
+    /init and /poll authenticate the caller through the session cookie +
+    CSRF token pair alone — no user login is required, since the whole point
+    of the flow is to bootstrap one. /exchange, by contrast, requires an
+    authenticated user and does not use the addonsSid cookie.
