scale-out: external NATS + multi-node fan-out (trio part 1)
events.Connect joins an external NATS so N nodes share one plane; --nats selects it (embedded stays the single-node default). Retention switched work-queue -> limits+cap: work-queue load-balanced one copy across nodes, leaving each index partial; limits fans out to per-node durables (name now carries a hashed node id) while MaxBytes/MaxAge keep disk bounded. Lease refusals surface as 503 (ops.ErrUnavailable), not 500. Verified live: two nodes on one external NATS + shared store, each folds the full store, the leased node writes while the other 503s and still folds the write cross-node. check-in: 89e4991bbf user: dmestas tags: trunk | |

lease: single-writer coordination (0001 §3)
NATS KV TTL lease per store keyed by project code. Write ops and sync pushes route through Guard: renew-or-acquire, failover grace after displacing a holder, commit-point re-check before the write, and writes-refuse when the coordinator is unreachable (correctness over availability). Single-node holds its own lease with no grace delay; the machinery and failure posture are identical at N nodes. Tests: mutual exclusion, failover, coordinator-down refusal. check-in: d1436c2071 user: dmestas tags: trunk | |
