From 74e3a03ba83b1b9a5f9b14f9cdcbd329e260e5e4 Mon Sep 17 00:00:00 2001 From: Eric Garcia Date: Sat, 24 Jan 2026 07:42:26 -0500 Subject: [PATCH] feat(realm): Implement RFC 0002 Phase 4 notifications Complete RFC 0002: Realm MCP Integration with notifications support. New MCP tool: - notifications_list: List notifications with state filters (pending, seen, expired, all) DaemonDb extensions: - cleanup_expired_notifications: Auto-delete 7+ day old notifications - list_notifications_with_state: Returns notifications with computed state Schema integrity checking: - Canonical JSON hashing (SHA-256) for schema fingerprinting - check_schema_integrity returns hashes for all accessible contracts - Integrated into realm_check response Notification piggybacking: - fetch_pending_notifications for realm_status and realm_check - Filtered to domains the current repo participates in RFC 0002 is now complete with all 8 tools: - Phase 1: realm_status, realm_check, contract_get - Phase 2: session_start, session_stop - Phase 3: realm_worktree_create, realm_pr_status - Phase 4: notifications_list Co-Authored-By: Claude Opus 4.5 --- Cargo.toml | 3 + crates/blue-core/src/daemon/db.rs | 50 ++++ crates/blue-mcp/Cargo.toml | 1 + crates/blue-mcp/src/handlers/realm.rs | 320 +++++++++++++++++++++++- crates/blue-mcp/src/server.rs | 31 +++ docs/rfcs/0002-realm-mcp-integration.md | 11 +- 6 files changed, 405 insertions(+), 11 deletions(-) diff --git a/Cargo.toml b/Cargo.toml index 352bf64..d2d9e18 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -62,6 +62,9 @@ dirs = "5.0" tower = { version = "0.5", features = ["util"] } http-body-util = "0.1" +# Crypto +sha2 = "0.10" + # Testing tempfile = "3.15" diff --git a/crates/blue-core/src/daemon/db.rs b/crates/blue-core/src/daemon/db.rs index 9bbc41f..4dcc269 100644 --- a/crates/blue-core/src/daemon/db.rs +++ b/crates/blue-core/src/daemon/db.rs @@ -469,6 +469,56 @@ impl DaemonDb { Ok(()) } + /// Delete notifications older than the specified number of days + pub fn cleanup_expired_notifications(&self, days: i64) -> Result { + let cutoff = (Utc::now() - chrono::Duration::days(days)).to_rfc3339(); + let deleted = self.conn.execute( + "DELETE FROM notifications WHERE created_at < ?", + params![cutoff], + )?; + Ok(deleted) + } + + /// List notifications for a realm filtered by state + /// State is determined by: pending (not acknowledged by current repo), + /// seen (acknowledged), expired (older than 7 days) + pub fn list_notifications_with_state( + &self, + realm: &str, + current_repo: &str, + state_filter: Option<&str>, + ) -> Result, DaemonDbError> { + let notifications = self.list_notifications_for_realm(realm)?; + let now = Utc::now(); + let expiry_days = 7; + + let with_state: Vec<(Notification, String)> = notifications + .into_iter() + .map(|n| { + let age_days = (now - n.created_at).num_days(); + let state = if age_days >= expiry_days { + "expired" + } else if n.acknowledged_by.contains(¤t_repo.to_string()) { + "seen" + } else { + "pending" + }; + (n, state.to_string()) + }) + .filter(|(_, state)| { + match state_filter { + Some("pending") => state == "pending", + Some("seen") => state == "seen", + Some("expired") => state == "expired", + Some("all") | None => true, + _ => true, + } + }) + .collect(); + + Ok(with_state) + } + fn row_to_notification(row: &rusqlite::Row) -> Result { Ok(Notification { id: row.get(0)?, diff --git a/crates/blue-mcp/Cargo.toml b/crates/blue-mcp/Cargo.toml index 755dff4..0694f87 100644 --- a/crates/blue-mcp/Cargo.toml +++ b/crates/blue-mcp/Cargo.toml @@ -17,6 +17,7 @@ tracing.workspace = true chrono.workspace = true git2.workspace = true regex.workspace = true +sha2.workspace = true [dev-dependencies] blue-core = { workspace = true, features = ["test-helpers"] } diff --git a/crates/blue-mcp/src/handlers/realm.rs b/crates/blue-mcp/src/handlers/realm.rs index 204d340..74a3806 100644 --- a/crates/blue-mcp/src/handlers/realm.rs +++ b/crates/blue-mcp/src/handlers/realm.rs @@ -10,12 +10,22 @@ //!
