- /offsite lists ALL wg_endpoints rows as cards (id, address, pubkey, subnet, PBS addr, peers-in-subnet count) + add/edit/delete forms - store: ListWGEndpoints (id order) + DeleteWGEndpoint (plain delete; the peers-in-subnet guard lives in the handler where the refusal is built); SetWGEndpoint upsert reused, single-expected comment updated - guards: subnet edit refused 409 while peers sit in the current subnet; endpoint delete refused 409 while peers sit in its subnet; full form validation (CIDR, pbs ip in subnet, port 1-65535, pubkey, id charset) -> 400 - peer table gains an Endpoint column (first id-ordered subnet match; em dash when none); pubkey-change edit gets a type-to-confirm noting pull-based convergence - allocation/reconciler/desired-state STAY lowest-endpoint-id (page notes the deferral); GetWGEndpoint semantics untouched - tests: E1-E6 incl. guard red-proofs; store list/delete test Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Vvz1NCu22p8dGkRCpeX9re
