Changelog — What's New in the Engine

In short

An engine you've bought updates for free: open your install link and hit "Update to the current core" — your settings and your own files carry over automatically, and no installation slots are consumed. This page is the core version log. Version 2.0 (July 2026) added: engine language selection (RU/EN), a default router for requests without a /command, a per-task task list that survives context loss, an "anti-sycophant" product owner, a 10/10 readiness gate with two honest outcomes, the /engine-tune and /engine-doctor commands, a QUICKSTART for getting going in 15 minutes, and circuit breaker v2, which now works in Cursor too.

Bought the engine? The updates are yours for free: open your install link and hit "Update to the current core." Your settings (language, your own files) carry over automatically, and no installation slots are consumed.

2.0 — 2026-07-02

Engine language: choose which language the engine speaks and writes documentation in (RU/EN) — a setting on the build page that flows into the package rules.
Default router: any request without a /command is handled by the engine (small stuff through the light loop, everything else through the full one), plus a reminder injected on every turn via a hook.
A task list per task: .quests/-/{spec,plan,tasks}.md — checkboxes are read before each step and updated after; context survives any interruption.
Anti-sycophant: the product owner on the team is no yes-man — it challenges even the things it agrees with and offers an alternative along with a recommendation.
10/10 readiness gate: exactly two outcomes — VERIFIED with the proofs actually executed, or an honest report of what's left; fabricated "done" is forbidden.
/engine-tune: have the agent tailor the engine to your project — on top of an untouched core, with a trivial rollback.
/engine-doctor and QUICKSTART: environment diagnostics with fix-it commands, and a 15-minute start for newcomers.
Circuit breaker v2: catches new classes of dangerous commands, works in Cursor too, and degrades honestly without jq.

1.0 — 2026-07-01

First release: a team of 8 specialists, a quest engine with phases and checks, 13 review prisms, a dangerous-command circuit breaker, a portable safety floor (git hook + CI), and unpack-based installation with a single manual step (Trust).
