Booster Go

Read the sibling skill ../booster-command/SKILL.md, then run command go through that runner.

Treat the rest of the user message as [fable] <Artifact Contract>. If the first token is fable, run the command's opt-in Семёрка-F mode: Fable is a read-only Quality Chair for Challenge and final watchlist closure, not Lead, Worker, Verifier, or a default route. During implementation the Verifier returns an evidence receipt from direct read-only probes; it does not create or rewrite test artifacts. Durable regression tests are created or updated only at the final deploy gate, after the direct probes pass.

For every non-trivial behavioral, data, runtime, external-system, incident-driven, or critical-component Prototype Gate, require the Prototyper's mandatory investigation notebook before Worker. It records direct authorized read-only commands/queries, source identity and environment, ISO timestamp or window, filters, counts/samples, expected versus actual, invariant result, and raw-output reference. It is durable under notebooks/ or reports/prototypes/, never tempdir; large raw output is repo-relative with SHA-256. It is an investigation journal, not a synthetic test stand; a paired probe script is not required. Notebook N/A is permitted only when the entire gate is explicitly N/A for a pure docs/format/static-config task with no executable data/runtime hypothesis and a concrete reason.
