8bit Tests the actual API components against Tuwunel, not raw fetch: - HttpAPI: processOutgoingCryptoRequests(), sendOutgoingCryptoRequest() - StructureAPI: room creation with m.room.encryption state - CommandAPI: encrypt + send via CryptoManager pipeline - TimelineAPI: sync → receiveSyncChanges → decrypt m.room.encrypted - Full round-trip: Alice sends 3 encrypted msgs, Bob decrypts all 3 All

BEFORE sync: Injects 'm.room.encrypted' into the server-side filter types. Without this, the server silently drops all encrypted events because it only sees the envelope type, not the original event type (e.g. io.syncpoint.odin.operation). 2. AFTER decrypt: Re-applies the original type constraint as a client-side filter. Since m.room.encrypted is a catch-all, any event type could be inside. The post-decrypt filter ensures only expected types pass through. This is fully transparent to ODIN — no filter changes needed in Project.content() or Project.start() filterProvider.

Solution: Share keys at TWO points: 1. At share time (shareLayer): Alice sends all Megolm session keys to ALL project members via to_device. These are queued server-side, so even if Bob is offline he receives them on next sync. 2. At join time (membershipChanged): Safety net that catches any keys created between share and join. Both paths use the new _shareHistoricalKeysWithProjectMembers() helper which handles device key query, Olm session establishment, and per-device Olm-encrypted to_device delivery. --- src/project.mjs | 107 ++++++++++++++++++++++++++++++++---------------- 1 file changed, 72 insertions(+), 35 deletions(-) diff --git a/src/project.mjs b/src/project.mjs index e1f4aaf..85d0052 100644 --- a/src/project.mjs +++ b/src/project.mjs @@ -131,6 +131,13 @@ Project.prototype.shareLayer = async function (layerId, name, description, optio await this.structureAPI.addLayerToProject(this.idMapping.get(this.projectId), layer.globalId) this.idMapping.remember(layerId, layer.globalId) + // Share historical Megolm keys with all project members at share time. + // This ensures that members who join later (even when we're offline) can + // decrypt the layer content, because to_device messages are queued server-side. + if (this.cryptoManager && options.encrypted) { + await this._shareHistoricalKeysWithProjectMembers(layer.globalId) + } + return { id: layerId, upstreamId: layer.globalId, @@ -157,6 +164,63 @@ Project.prototype.joinLayer = async function (layerId) { return layer } +/** + * Share all historical Megolm session keys for a room with all project members. + * Used at share time (when creating/sharing a layer) and when new members join. + * to_device messages are queued server-side, so offline recipients get them on next sync. + * @private + */ +Project.prototype._shareHistoricalKeysWithProjectMembers = async function (roomId, targetUserIds) { + const log = getLogger() + const myUserId = this.timelineAPI.credentials().user_id + + try { + // If no specific targets, get all project members + let userIds = targetUserIds + if (!userIds) { + const projectRoomId = this.idMapping.get(this.projectId) + const members = await this.commandAPI.httpAPI.members(projectRoomId) + userIds = (members.chunk || []) + .filter(e => e.content?.membership === 'join') + .map(e => e.state_key) + .filter(id => id !== myUserId) + } + + if (userIds.length === 0) return + + for (const userId of userIds) { + try { + // Ensure we have the user's device keys + await this.cryptoManager.updateTrackedUsers([userId]) + const keysQueryRequest = await this.cryptoManager.queryKeysForUsers([userId]) + if (keysQueryRequest) { + const queryResponse = await this.commandAPI.httpAPI.sendOutgoingCryptoRequest(keysQueryRequest) + await this.cryptoManager.markRequestAsSent(keysQueryRequest.id, keysQueryRequest.type, queryResponse) + } + + // Establish Olm sessions if needed + const claimRequest = await this.cryptoManager.getMissingSessions([userId]) + if (claimRequest) { + const claimResponse = await this.commandAPI.httpAPI.sendOutgoingCryptoRequest(claimRequest) + await this.cryptoManager.markRequestAsSent(claimRequest.id, claimRequest.type, claimResponse) + } + + // Export and share historical keys + const { toDeviceMessages, keyCount } = await this.cryptoManager.shareHistoricalRoomKeys(roomId, userId) + if (keyCount > 0) { + const txnId = `odin_keyshare_${Date.now()}_${Math.random().toString(36).slice(2)}` + await this.commandAPI.httpAPI.sendToDevice('m.room.encrypted', txnId, toDeviceMessages) + log.info(`Shared ${keyCount} historical keys with ${userId} for room ${roomId}`) + } + } catch (err) { + log.warn(`Failed to share historical keys with ${userId}: ${err.message}`) + } + } + } catch (err) { + log.warn(`Failed to share historical keys for room ${roomId}: ${err.message}`) + } +} + Project.prototype.leaveLayer = async function (layerId) { const upstreamId = this.idMapping.get(layerId) const layer = await this.structureAPI.getLayer(upstreamId) @@ -365,46 +429,19 @@ Project.prototype.start = async function (streamToken, handler = {}) { })) await streamHandler.membershipChanged(membership) -
