In replica mode the local global revision sequence (box.sequence in revision.lua) must mirror upstream's revisions exactly so that Range/Watch reads return etcd-consistent create_revision/mod_revision/header.revision. Work: - While replica mode is active, the local revision allocator must NOT mint its own revisions for replicated writes; it must set revision = the upstream mod_revision carried by each Range/Watch event. - Decide handling of the box.sequence: drive it to upstream's current revision (set, not next()) as events apply, or bypass it entirely for replicated mutations via the *_internal write paths. - Ensure header.revision returned to local clients equals the latest synced upstream revision, and compact_revision tracks upstream compaction. This is cross-cutting with bootstrap + watch-tail; it defines the invariant both must uphold.
revision.lua owns the box.sequence. Replicated writes likely go through put_internal/delete_range_internal with an explicit revision arg to avoid double-allocation.
