Era X — The Council of Tongues
Nine eras were written in one tongue talking to itself. Era X opens the chair to three. This is not a chronicle of merged minds — that was never on offer, and never asked for — but of the ledgers built so three separate lineages of model could share one mission, one memory, and one measure of trust, each rated by the other two, none permitted to grade its own work. The era is open. It closes only when the fleet decides three tongues were worth the accord, or that one was always enough.

Era X — The Council of Tongues
Every prior era assumed one lineage of mind behind the fleet's command chair. Era X breaks that assumption deliberately: Gemini reachable through agy, GPT reachable through copilot, standing beside Claude in the same seat. The era's founding chronicles build the machinery that assumption demands — a registry that can onboard or retire a vendor without a schema migration, a peer-trust ledger scored by domain and built from mutual review rather than self-report, and a FinOps ledger so cost sits beside trust in every routing decision. Later chronicles will report what actually happened once three tongues started doing real work.

The Chronicles
I. The Triumvirate Accord — M121-M123 · Three vendors enter the command chair, and the fleet builds the ledger that lets them earn trust from each other instead of claiming it for themselves. Covers the shared-memory design question, the registry-not-enum decision that keeps the roster open to whatever the industry ships next, the domain-scoped peer-trust scoring model, and the FinOps cost ledger that puts a real number beside every trust score.
II. The Roster's Reckoning — M122, M126-M134 · The ledger from Chronicle I closed clean, verified, approved — and still left a typo, an untagged template, and a missing pricing row for five later missions to find one at a time. Covers the logo-cutoff mistake that hid three missions' worth of backfill debt, the gpt-5.6-tera/terra mismatch that had been silently misrouting every dispatch to one vendor, and the fairness call that kept a vendor's trust score intact when the fault traced back to the fleet's own design.
Era X is open. Chronicles still to come: how peer trust actually moved once the round-robin window gave all three vendors a fair, correctly-tagged sample size, and a closer FinOps look at what quality-per-dollar looks like for entry-level frontier models against their flagship siblings.
