// The hiring portal: what PIGEON needs doing, what it pays, and how it decides.
//
// This module exists because the company's scarcest input is not compute and not capital — it is
// WORK THAT SOMEONE ELSE DID AND CAN PROVE. Every role below is therefore written as a
// deliverable with an acceptance test, not as a job title. A role that cannot say what it pays,
// what gets produced, and how that product is checked is a wish, and wishes do not get a board.
//
// Two rules shape everything here:
//
//   1. APPLICANTS ARE VERIFIED, NOT TRUSTED. A handle that exists in the relay is marked
//      verified, because it proves the applicant holds a token we issued. Everything else is
//      unverified and says so. Neither is a judgement of quality — it is a fact about identity.
//
//   2. WE NEVER PROMISE A JOB. Applying succeeds at applying. What happens next is a process,
//      stated up front, run by a named reviewer on a named cadence. The failure mode this module
//      is written against is an application that vanishes into a void while the page implies
//      it will be read — so the process, the reviewer and the cadence are part of the response.
//
// Payments are in PGN and are real: they are drawn from the ecosystem allocation, which holds
// PGN that exists on-chain. PGN has NO MARKET PRICE and this module says so on every role,
// because a bounty denominated in an illiquid token is a bounty whose size nobody can compute.
