From d30a1c23c82d738c48d89dbf112ced6c5045f8b7 Mon Sep 17 00:00:00 2001 From: Tyler Longwell Date: Tue, 10 Mar 2026 14:17:33 -0400 Subject: [PATCH] feat: channel management, messaging, threads, DMs, reactions, and NIP-29 support Add comprehensive channel features implementing the REST + NIP-29 dual API architecture. Both paths converge on shared DB functions as the single source of truth. New capabilities: - Channel metadata (topic, purpose, archive/unarchive) - Membership management (add, remove, join, leave) with role-based auth - Threaded messaging with materialized reply/descendant counts - Direct messages with immutable participant sets (SHA-256 hash) - Emoji reactions with atomic upsert - NIP-29 relay protocol (kinds 9000-9022) with pre-storage validation - 19 new MCP tools for agent interaction - Relay keypair infrastructure for system messages (kind 40099) 6 migrations, 16 new files, 12 modified files (~1,420 insertions). --- crates/sprout-core/src/kind.rs | 3 + crates/sprout-db/src/channel.rs | 275 ++++++- crates/sprout-db/src/dm.rs | 443 ++++++++++ crates/sprout-db/src/lib.rs | 202 +++++ crates/sprout-db/src/reaction.rs | 262 ++++++ crates/sprout-db/src/thread.rs | 567 +++++++++++++ crates/sprout-db/src/user.rs | 75 ++ crates/sprout-mcp/src/server.rs | 754 +++++++++++++++++- .../sprout-relay/src/api/channels_metadata.rs | 430 ++++++++++ crates/sprout-relay/src/api/dms.rs | 347 ++++++++ crates/sprout-relay/src/api/members.rs | 422 ++++++++++ crates/sprout-relay/src/api/messages.rs | 488 ++++++++++++ crates/sprout-relay/src/api/mod.rs | 21 + crates/sprout-relay/src/api/reactions.rs | 298 +++++++ crates/sprout-relay/src/api/users.rs | 93 +++ crates/sprout-relay/src/config.rs | 6 + crates/sprout-relay/src/handlers/event.rs | 50 +- crates/sprout-relay/src/handlers/mod.rs | 2 + .../sprout-relay/src/handlers/side_effects.rs | 592 ++++++++++++++ crates/sprout-relay/src/main.rs | 9 + crates/sprout-relay/src/router.rs | 66 +- crates/sprout-relay/src/state.rs | 5 + migrations/20260310000001_events_id_index.sql | 1 + .../20260311000001_channel_metadata.sql | 16 + migrations/20260312000001_thread_metadata.sql | 21 + .../20260312000002_events_deleted_at.sql | 2 + .../20260313000001_dm_participant_hash.sql | 10 + migrations/20260314000001_reactions.sql | 12 + 28 files changed, 5418 insertions(+), 54 deletions(-) create mode 100644 crates/sprout-db/src/dm.rs create mode 100644 crates/sprout-db/src/reaction.rs create mode 100644 crates/sprout-db/src/thread.rs create mode 100644 crates/sprout-relay/src/api/channels_metadata.rs create mode 100644 crates/sprout-relay/src/api/dms.rs create mode 100644 crates/sprout-relay/src/api/members.rs create mode 100644 crates/sprout-relay/src/api/messages.rs create mode 100644 crates/sprout-relay/src/api/reactions.rs create mode 100644 crates/sprout-relay/src/api/users.rs create mode 100644 crates/sprout-relay/src/handlers/side_effects.rs create mode 100644 migrations/20260310000001_events_id_index.sql create mode 100644 migrations/20260311000001_channel_metadata.sql create mode 100644 migrations/20260312000001_thread_metadata.sql create mode 100644 migrations/20260312000002_events_deleted_at.sql create mode 100644 migrations/20260313000001_dm_participant_hash.sql create mode 100644 migrations/20260314000001_reactions.sql diff --git a/crates/sprout-core/src/kind.rs b/crates/sprout-core/src/kind.rs index 931269e..21cd2c9 100644 --- a/crates/sprout-core/src/kind.rs +++ b/crates/sprout-core/src/kind.rs @@ -86,6 +86,8 @@ pub const KIND_STREAM_MESSAGE_SCHEDULED: u32 = 40006; pub const KIND_STREAM_REMINDER: u32 = 40007; /// Canvas (shared document) for a channel. pub const KIND_CANVAS: u32 = 40100; +/// System message for channel state changes (join, leave, rename, etc.). +pub const KIND_SYSTEM_MESSAGE: u32 = 40099; // Direct messages (41000–41999) /// A new direct-message conversation was created. @@ -225,6 +227,7 @@ pub const ALL_KINDS: &[u32] = &[ KIND_STREAM_MESSAGE_SCHEDULED, KIND_STREAM_REMINDER, KIND_CANVAS, + KIND_SYSTEM_MESSAGE, KIND_DM_CREATED, KIND_DM_MEMBER_ADDED, KIND_DM_MEMBER_REMOVED, diff --git a/crates/sprout-db/src/channel.rs b/crates/sprout-db/src/channel.rs index 29cb8f8..17be3de 100644 --- a/crates/sprout-db/src/channel.rs +++ b/crates/sprout-db/src/channel.rs @@ -166,6 +166,18 @@ pub struct ChannelRecord { pub topic_required: bool, /// Optional cap on the number of members. pub max_members: Option, + /// Current channel topic (short, visible in header). + pub topic: Option, + /// Compressed public key bytes of the user who last set the topic. + pub topic_set_by: Option>, + /// When the topic was last set. + pub topic_set_at: Option>, + /// Channel purpose / description of intent. + pub purpose: Option, + /// Compressed public key bytes of the user who last set the purpose. + pub purpose_set_by: Option>, + /// When the purpose was last set. + pub purpose_set_at: Option>, } /// A channel membership row as returned from the database. @@ -241,7 +253,9 @@ pub async fn create_channel( r#" SELECT id, name, channel_type, visibility, description, canvas, created_by, created_at, updated_at, archived_at, deleted_at, - nip29_group_id, topic_required, max_members + nip29_group_id, topic_required, max_members, + topic, topic_set_by, topic_set_at, + purpose, purpose_set_by, purpose_set_at FROM channels WHERE id = ?
