 ### End-to-end encryption
 
-La Suite Meet supports end-to-end encryption (E2EE) for meetings, ensuring that the media server (LiveKit SFU) cannot access audio/video content. Two encryption modes are available:
+La Suite Meet supports end-to-end encryption (E2EE) for meetings, so the media server (LiveKit SFU) cannot read audio, video or screen-share content.
 
-#### Basic encryption
+#### How it works
 
-- Passphrase-based — the encryption key is embedded in the meeting URL hash (`#passphrase`)
-- Uses LiveKit's built-in Worker + `crypto.subtle` (AES-GCM) for frame encryption
-- Sharing the meeting link shares the encryption key
-- No account or onboarding required
-- Security depends on keeping the link private
+- Each encrypted meeting carries a 48-character random passphrase appended to the URL hash (`#…`). The server never sees it; sharing the meeting link shares the key.
+- Frames are encrypted in the browser via LiveKit's Worker + `crypto.subtle` (AES-GCM); only the media payload is encrypted, codec headers stay clear so the SFU can still packetize RTP.
+- The runtime "is this call encrypted?" decision keys off the URL hash, not the database flag — a compromised server cannot fabricate a passphrase that all participants happen to share.
+- The DB flag (`Room.is_encrypted`) is a hint used at room creation time only (so the Create button knows to generate a hash) and to detect link/server inconsistencies.
 
-#### Advanced encryption
+#### Opt-in by user
 
-- Key managed by [La Suite Encryption](https://github.com/suitenumerique/encryption) — the symmetric key never leaves the vault iframe
-- Uses XChaCha20-Poly1305 (libsodium) via the VaultClient iframe for frame encryption
-- Key distribution uses `vaultClient.shareKeys()` (hybrid PKI with X25519 + post-quantum slot)
-- All participants must complete encryption onboarding (key generation + backup) before joining
-- Requires a Chromium-based browser (Chrome, Edge, Brave) — uses the Insertable Streams API
+End-to-end encryption is a per-user preference. In **Settings → Security**, signed-in users can enable "End-to-end encryption" — from then on every meeting they create is encrypted by default. Joining is unaffected: if a meeting URL has a passphrase, the joining client uses it.
 
-**Frame encryption (both modes):**
+#### Pause / resume for recording and transcription
 
-- Codec header bytes (VP8 payload descriptor) are preserved unencrypted — required for proper RTP packetization
-- Only the media payload is encrypted, with a per-frame random nonce
-- The server (LiveKit SFU) only forwards encrypted data it cannot read
+While encryption is on, the SFU cannot record or transcribe (it has nothing to read). When an admin (or, if no admin is present, the longest-present participant — provided a pause has already been observed in the session) starts a recording or transcription:
 
-**Trust levels (advanced mode):**
-| Badge | Level | Description |
-|-------|-------|-------------|
-| 🟢 Green shield | Verified | User completed encryption onboarding (public key registered). Identity cryptographically verified. |
-| 🔵 Blue shield | Authenticated | User signed in via ProConnect/OIDC. Identity server-verified. |
-| 🟡 Orange warning | Anonymous | User not signed in. Self-declared name. Admin should verify identity before accepting. |
+1. A confirmation dialog warns that encryption will be paused.
+2. On confirm, an `ENCRYPTION_PAUSED` message is broadcast over a LiveKit reliable data channel. While the sender hasn't yet flipped its own state, that message is itself encrypted — which is the trust anchor: only callers holding the passphrase can produce frames everyone can decrypt.
+3. Each receiver disables E2EE locally and republishes its tracks unencrypted.
+4. Late joiners send an `ENCRYPTION_STATUS_PROBE` so the leader can re-emit the announcement to them.
+5. When **both** recording and transcription stop, the participant who paused broadcasts `ENCRYPTION_RESUMED` and everyone re-enables E2EE with the same URL passphrase.
 
-**Security guarantees:**
+The pause state is intentionally session-only and never persisted — `Room.is_encrypted` does not flip.
 
-- Encrypted rooms enforce restricted access (lobby approval required)
-- Trust information (`is_authenticated`, `email`) comes from server-signed JWT tokens — cannot be spoofed
-- Recording and transcription are not available in encrypted rooms (server cannot decrypt media)
+#### Phone / SIP participants
 
-**Configuration:**
+Phone and other external devices can't decrypt our frames. When one joins an encrypted room, the backend webhook detects them, broadcasts a system notice (admins see a snackbar with an "Open settings" CTA), and removes the external participant. The admin can then disable encryption from the Security settings and the user can dial in again.
+
+#### Configuration
 
 ```env
 ENCRYPTION_ENABLED=true
-ENCRYPTION_VAULT_URL=https://data.encryption.example.fr
-ENCRYPTION_INTERFACE_URL=https://encryption.example.fr
 ```
 
-When the encryption service is deployed and configured, rooms can use advanced encryption. Without it, only basic (passphrase) encryption is available.
+Setting `ENCRYPTION_ENABLED=false` disables the user preference toggle entirely; existing encrypted rooms stay encrypted but no new ones can be created.

-    # - suite_user_id: required for vault key exchange in advanced encryption
-    #   (vaultClient.shareKeys needs the recipient's user ID)
-    #
-    # These attributes are NOT included in non-encrypted rooms because:
-    # - Non-encrypted rooms have no waiting room, so anonymous users can join
-    #   freely and would see everyone's email via LiveKit signaling
-    # - LiveKit JWT attributes are immutable and broadcast to ALL participants
-    #   equally — there is no way to show them only to authenticated users
-    #   at the protocol level
-    # - The frontend additionally hides email from anonymous users in the UI,
-    #   but this is defense-in-depth, not the primary protection
-    #
-    # Future improvement: serve email via a Django API endpoint that checks
-    # the requester's authentication, removing it from the JWT entirely.
-    # This would require the backend to call LiveKit's ListParticipants API
-    # to cross-reference identities with the user database.

+/**
+ * In-call encryption state machine and pause protocol.
+ *
+ * Three phases:
+ *  - UNENCRYPTED   — the room is not end-to-end encrypted.
+ *  - ENCRYPTED     — E2EE is active; frames are encrypted with the URL passphrase.
+ *  - PAUSED        — encryption is temporarily paused for this session, typically
+ *                    so the SFU can record / transcribe.
+ *
+ * The "paused" state is intentionally ephemeral: it is never persisted in the
+ * database. The truth source for "this call is encrypted" is the presence of
+ * the passphrase in the URL hash, not a server-side flag — a hacked server
+ * cannot fabricate a passphrase that all participants happen to share.
+ *
+ * Pause is broadcast over a LiveKit reliable data channel. While the sender
+ * has not yet flipped its own state, the message itself travels encrypted,
+ * which is the trust anchor: only callers who hold the passphrase can produce
+ * frames everyone can decrypt.
+ *
+ * Pause is reversible: when both recording and transcription have stopped,
+ * the participant who initiated the pause broadcasts ENCRYPTION_RESUMED and
+ * everyone re-enables E2EE with the same URL passphrase.
+ *
+ * Initiation: admins can always pause/resume. If no admin is in the room and
+ * a pause has already been observed in this session (everSeenPause), the
+ * leader (oldest non-SIP participant) may also pause/resume — this covers
+ * the "the admin left mid-call" edge case without granting unsolicited
+ * pause power to non-admins.

-# Encryption Security Architecture
-
-## Threat model
-
-### What E2EE protects against
-- **Server-side data access**: The LiveKit SFU and Meet backend cannot read audio/video content
-- **Network interception**: Media frames are encrypted before leaving the client
-- **Unauthorized participants**: Restricted access + lobby ensures only admin-approved users join
-
-### Known limitations and mitigations
-
-#### Compromised LiveKit server (MITM on key exchange)
-
-**Threat**: If the LiveKit server is compromised, it could perform a Man-in-the-Middle attack on the ephemeral DH key exchange, intercepting the symmetric key.
-
-**Current mitigation**: KEY_RESPONSE is only accepted from participants with `room_admin: "true"` in their server-signed JWT attributes. This prevents non-admin participants from injecting fake keys, but does not protect against a compromised server that can forge JWT attributes.
-
-**Planned mitigations (3 levels):**
-
-##### Level 1 — Signed key exchange (requires encryption onboarding)
-
-When the admin has completed encryption onboarding via `data.encryption`:
-1. Admin signs the KEY_RESPONSE with their permanent private key (stored in IndexedDB)
-2. Receiving participant fetches admin's public key from `data.encryption` registry
-3. Verifies the signature before accepting the symmetric key
-4. If signature is invalid → **reject the key, show error, cut video**
-
-This protects against server compromise because the server cannot forge the admin's private key signature.
-
-**Requirement**: Admin must have completed encryption onboarding. If not, falls back to Level 2.
-
-##### Level 2 — SAS (Short Authentication String) verification
-
-After the ephemeral DH key exchange:
-1. Both parties compute SAS = hash(DH_shared_secret) → displayed as 4 emojis or a 6-digit code
-2. Each participant sees the SAS on their own screen (local rendering)
-3. They read it aloud to each other during the call
-4. If the SAS matches → the key exchange was not intercepted
-5. If the SAS doesn't match → MITM detected → reject the key
-
-This works because:
-- A MITM results in different DH shared secrets → different SAS codes
-- The SAS is rendered locally — the server cannot change what appears on screen
-- Real-time audio manipulation to fake the spoken SAS is extremely difficult
-
-**Requirement**: Participants must verbally compare the SAS. Optional but recommended.
-
-##### Level 3 — Trust the server (current default)
-
-Relies on the LiveKit server's integrity (JWT-signed attributes). Suitable when:
-- The server infrastructure is self-hosted and trusted
-- The threat model does not include server compromise
-- Quick, frictionless meetings are prioritized over maximum security
-
-#### Key propagation without admin
-
-**Current behavior**: Any participant who has the symmetric key can relay it to new joiners.
-
-**Risk**: If the server is compromised, it could inject a fake participant who relays a compromised key.
-
-**Planned fix**: Only accept KEY_RESPONSE from participants whose identity can be:
-- Cryptographically verified (Level 1 — signature from registered public key), or
-- Manually verified (Level 2 — SAS comparison)
-
-Non-verified key relays should show a clear warning.
-
-## Trust levels
-
-| Level | Badge | Identity verification | Key exchange | Server compromise protection |
-|-------|-------|----------------------|-------------|------------------------------|
-| Verified | 🟢 Green shield | Public key registered in `data.encryption` | Signed with permanent private key | Yes — signature cannot be forged |
-| Authenticated | 🔵 Blue shield | OIDC/ProConnect login | Ephemeral DH (unsigned) | No — relies on server integrity |
-| Anonymous | 🟡 Orange warning | None (self-declared name) | Ephemeral DH (unsigned) | No — relies on server integrity |
-
-#### Basic mode: unencrypted frame window on connection
-
-**Behavior**: LiveKit's built-in Worker passes frames through unencrypted when `!isEnabled()`.
-
-**Mitigation**: `setE2EEEnabled(true)` is called BEFORE the room connects (in Conference.tsx),
-ensuring the 'enable' message reaches the Worker before any frames flow. This eliminates the
-unencrypted window in normal operation. However, edge cases (Worker message queue delays,
-race conditions during reconnection) could theoretically still allow a few unencrypted frames.
-
-**Advanced mode**: VaultE2EEManager drops frames when the key isn't ready — no pass-through.
-
-#### Basic mode: "Decryption failed" overlay may not appear with wrong passphrase
-
-**Behavior**: When a participant joins with a wrong passphrase, the receiver may not show the
-"Decryption failed" overlay. The LiveKit Worker's error throttling (`MAX_ERRORS_PER_MINUTE = 5`)
-stops emitting `EncryptionError` events after 5 failures. Additionally, when a participant
-reconnects, the new `ParticipantTile` mounts fresh and may not receive errors referencing
-the new participant identity.
-
-**Impact**: The user sees a black tile but no error message explaining why.
-
-**Advanced mode**: VaultE2EEManager emits `EncryptionError` for each failure and signals
-`ParticipantEncryptionStatusChanged(true)` on first successful decrypt, ensuring the overlay
-appears and clears correctly.
-
-## Implementation status
