p-e relay (remote)

Each tool has a clearly distinct role: append_relay writes, exists checks state, get_relay fetches bytes, list_relays surveys the corpus, list_replies finds references to one id, and wait_for_relay blocks for new records. The descriptions explicitly disambiguate the two closest tools, exists and get_relay, by stating when to use each.

Tool names are consistently snake_case and mostly follow a verb_noun pattern with relay(s) as the object. The main deviation is exists, which lacks an explicit object, but it is still clear and does not create confusion.

Six tools is well-scoped for an append-only relay store: one write operation, one existence check, one byte fetch, two listing/query operations, and one wait operation. Every tool earns its place with no redundancy.

The tool surface covers the full lifecycle of an append-only record store: append, read by id, existence check, full corpus listing, reply traversal, and waiting for new records. Update and delete are intentionally absent for an append-only design, so there are no meaningful gaps.
