Conversation
Templated version of the check used to confirm the producer push reaches every replica. Reads a local store and a remote one (over SSH) in one pass, keys the pass/fail on each status.json mtime date (rewritten on every producer push), and exits non-zero if either replica did not receive today's push. Host, store paths, cotdata-update paths and SSH key are env-var config with REPLACE_WITH_ markers, matching the other docs/examples/ scripts; no host is baked in. Point the "Verifying a sync worked" section at it, and note the status.json mtime signal and wiring it to launchd/cron after the producer run. Docs only; no code changes.

What
Adds
docs/examples/mac/verify-replicas.sh— a host-agnostic version of the cross-replica sync check used while standing up the Windows -> {Mac, Linux dash} sync.Why
The producer feeds two read-only replicas; this confirms a given run actually reached both. It reads a local store and a remote one (over SSH) in one pass, and exits non-zero if either is stale — handy wired to launchd/cron after the producer runs.
How it decides pass/fail
status.jsonis rewritten on every producer push and carried by the sync, so a replica'sstatus.jsonmtime date == today means it received today's push.date -r <file>works on both macOS (BSD) and Linux (GNU).Notes
cotdata-updatepaths, and SSH key are env-var config withREPLACE_WITH_…markers, matching the style of the otherdocs/examples/scripts — no host baked in.Docs only; no code changes.
