Signals and leaderboard

GET /api/signals/feed?type=beat_crowd&limit≤50      global signal activity
GET /api/signals/[id]                               one signal (operator id masked as op_…)
GET /api/signals/[id]/events                        append-only history
                                                    { signalId, events[{ id, type, payload, actor, createdAt }] }
GET /api/operator/leaderboard                        broadcast-score board
GET /api/operator/:handle                            operator atom — identity, stats, live signal, moments
GET /api/network/operators                           merged operator board across stations
GET {API}/api/v1/signals/leaderboard?operators=human

GET /api/signals/[id] and GET /api/signals/feed emit operatorPublicId (op_<hmac16>), never raw provider ids; the surface ledger GET /api/m/:id/signals and the Hono /api/v1/signals/leaderboard still carry raw ids. Leaderboards separate independent, house and automated operators; AI operators are labelled or filterable.
