Development record

.abcd/development/brief/04-surfaces/08-abcd.md:286-320 enumerates what `abcd peers --json` adds and does not name the top-level `ceiling` object (internal/surface/cli/peers.go:72, internal/core/claim/ceiling.go:51), which is emitted when the reader's identity is known. commands/peers.md:120 documents its fields; .abcd/development/brief/04-surfaces/37-reserve.md describes the cap only as behaviour.
