Collapse three byte-identical response-parsing blocks (getRelay, postRelay, and the tts error path) into one handleRelayResponse helper. pingBalance is deliberately left out: it records a relay error even on a parsed envelope, a different contract from the other three (updateRelayState clears lastError while recordRelayError sets it), so folding it in would change observable state. Collapse the six operator-to-relay calls into operatorPost / operatorGet, preserving their intentional split: writes (tier grant, invoice, order) throw on misconfig or non-OK so the operator action surfaces the failure; reads (tier, plans, expiring subs) return null so the caller falls back to a default. Per-function signatures, body shapes, error messages, and the throw-vs-null behavior are unchanged. Add server/test/relay.test.js (first fetch-mock harness for relay.js): 14 tests covering the tts error-path control flow, handleRelayResponse's envelope parsing and error-recording rule, and the operator throw-vs-null contract including the missing-config branch. 158 tests pass. ROADMAP gains the deferred refactor-survey items (subscription engine, /api/process pipeline, sweep middleware, transcript coalescers) and notes the relay-test coverage against the existing known-debt entries.
