Era X: the fleet's command chair opens to three vendors at once — Claude, Gemini, GPT — and builds the peer-trust and FinOps ledgers needed to let three tongues earn the fleet's confidence without any one of them grading its own homework. Missions M121 onward.
Cost tracking existed, worked, and was completely optional — which meant it was skippable in practice. Making it mandatory nearly locked every captain out of the ledger permanently. The fix that actually worked was the opposite of strict: never refuse, always estimate, always disclose.
A trust ledger is only as honest as the cost figures sitting next to it. M134 found a vendor with zero cost records at all, M149 spent three attempts finding out how wrong a cheap estimate can be, and M153 caught the audit itself drifting before M154 finally made the whole problem automatic.
M122 built the trust ledger clean in five milestones. Then five more missions chased the same bug across the command-center graph before the fleet found the typo underneath it all.
M130 gave the round-robin its fair, correctly-tagged sample. M145 closed it and read the numbers back — a real dollar figure, a real quality signal, and an honest admission that the sample is still too thin for the last word.
M121-M123: the fleet opened its command chair to three vendors at once — <Term id="claude">Claude</Term>, <Term id="gemini">Gemini</Term>, <Term id="gpt">GPT</Term> — and had to answer, before any of them touched a shared task, how three tongues could earn trust without one of them grading its own homework.
The scorecard in The Rotation's Verdict looked honest because nobody had checked whether the labels underneath it were true. M137-M139 found out they weren't - a mis-grouped graph, three delegations that ran on a vendor other than the one they were logged under, and a fix deployed to a container nobody was actually serving traffic from.
