The three live voters disagree on signal aggregates for the same entity
(view = 10003 / 10095 / 10144 for entity 1, stable across passes) while
`/cluster/status` reports applied_events equal, lag_events 0, and no divergence
quarantine. The documented remedy is `POST /cluster/reconcile`. On this corpus
it fails:
503 region 'tidaldb-1' unreachable:
reconcile peer returned 413 Payload Too Large
Two defects, both fixed here:
- The whole-shard CRDT `StateSnapshot` was capped by `BODY_LIMIT_BYTES`, the
2 MiB limit sized for one client write on the public data surface. The
snapshot carries one entry per entity x signal type; on 33k documents it is
several MiB, so divergence was unhealable in production. The internal,
marker-pinned, operator-driven snapshot route now has its own explicit
ceiling.
- A 413 was reported as `RegionUnreachable`. The peer answered - it is
reachable and healthy - so the error sent the operator to TLS and
NetworkPolicy. It now names the measured snapshot size, the peer's cap, and
the fix.
The ceiling is not the design: the snapshot grows with the corpus and chunked
reconcile is the durable answer. Documented as such at the constant.
