Problem

Graph metrics panel in TUI always shows zeros (entities: 0, edges: 0, communities: 0) despite the database containing real data (138 entities, 388 edges confirmed via sqlite3).

Two separate root causes identified.

Root Cause 1: Initial value lost at startup

sync_graph_counts() is called in src/runner.rs:1237 before the TUI receiver is created. Tokio watch::Receiver marks the initial value as has_changed = false, so poll_metrics() skips it on the first poll and graph counts never appear.

// app.rs — poll_metrics() only reads when has_changed = true
if let Some(ref mut rx) = self.metrics_rx
    && rx.has_changed().unwrap_or(false)  // false at startup → skipped

Fix: Read the initial value eagerly in with_metrics_rx():

pub fn with_metrics_rx(mut self, rx: watch::Receiver<MetricsSnapshot>) -> Self {
    self.metrics = rx.borrow().clone(); // read initial value immediately
    self.metrics_rx = Some(rx);
    self
}

Root Cause 2: sync_graph_counts() called before extraction completes

sync_graph_counts() is called at the end of process_user_message_inner() immediately after analyze_and_learn(). However, graph extraction is fire-and-forget (tokio::spawn) — the spawn has not completed by the time sync_graph_counts() reads from the store, so it reads stale counts.

self.analyze_and_learn().await;  // spawns extraction task (fire-and-forget)
self.sync_graph_counts().await;  // reads BEFORE spawn finishes → stale data

Fix: Call sync_graph_counts() as a callback inside the extraction spawn after it completes, or add a post-extraction notification mechanism so counts are refreshed after the spawn finishes.
