+# Clock inventory for #821 Step 1
+
+HEAD: 886463ef master (2026-09-27) Merge #823 - latest, 100 sites
+Command: rg -n "SystemTime::now()" crates/ --type rust -g '!*tests*' --no-heading | sort
+
+Summary from your run:
+- 10 crates/rbitcoin-store/src/bulk_io.rs -> log/perf LEAVE
+- 6 crates/rbitcoin-node/src/run.rs -> mostly log/perf
+- 5 crates/rbitcoin-store/src/bdz.rs -> log/perf LEAVE
+- 4+4+4 peer.rs, spender_table, scripthash_head -> mix
+- 3 peers.rs:1249 mock_now Acquire/Release + set_mock_now() bypasses hub.clock -> CRITICAL MIGRATE (split-brain), tx_relay.rs:625 mock_now Relaxed + note_mock_now() bypasses hub.clock -> CRITICAL MIGRATE, service.rs/seeds.rs -> node-time
+- 2 tx_relay.rs -> 1x node-time (928 manual mock -> NodeClock), 1x log/perf (3753 tmp uniqueness) LEAVE
+
+Legend per Rearden #688 item 2.1:
+- log/perf: log stamps, metrics, perf timers - LEAVE as SystemTime::now()
+- node-time: consensus / net / mempool / rpc - MIGRATE to NodeClock
+- wall: explicitly wants wall even under mocktime (INV age gate)
