rating-change-risk

Picks Quick, Standard, or a stronger human-reviewed mode based on consequence, how easy it is to undo, and how much is unknown. Use when you start a change to code, docs, dependencies, AI power, releases, or public claims and the right level of care is unclear. Do not use for a tiny easy-to-undo edit with obvious proof, which is Quick by default, or for a purely administrative reversible edit crossing no trust boundary, which needs no packet at all.

# Rating Change Risk

## Overview

Sort the change before you build it. That way the care you take matches the stakes and the evidence the change needs. The result is a mode choice, tied to the decision question, what the change must prove, and the triggers to escalate. Choosing the mode is how Nuclear-grade *tailors* rigor to stakes — the same idea project-management practice calls tailoring; see `docs/02-operating-system/risk-tiers-and-modes.md`. Mode is about how much rigor; it is orthogonal to the work type (greenfield, brownfield, defect-fix, or refactor-migration), which is classified upstream in `questioning-attitude` and shapes which questions you ask. See `docs/02-operating-system/work-type-lens.md`. The archetype classified there sets a **floor** under the mode you pick (see `docs/02-operating-system/archetype-lens.md`); if the archetype shifts mid-change -- the prototype someone decides to ship -- re-grade, because the stakes moved even though the diff did not.

## Decision contract

- **Claim checked:** the chosen mode matches the stakes -- Quick only for local, easy-to-undo, easy-to-prove work that adds no new trust boundary, and Standard or stronger once consequence, exposure, reversibility, detectability, unknowns, or agent power cross the line -- and the proof that mode owes is named.
- **Artifact observed:** the request/diff, the files/dependencies/credentials/APIs/users touched, `activation-thresholds.md`, and any prior `risk.md` -> the mode, decision question, evidence bar, required files, proof command or gap, and escalation triggers in `risk.md`.
- **Decision affected:** block -- the mode (Quick / Standard / stronger) and the evidence obligation that mode sets.
- **Failure class:** underrated-mode (a mode picked from effort, not stakes, weaker than the obvious consequence).
- **Next action:** raise the mode to fit the stakes; escalate when money, sensitive data, irreversible actions, autonomous tools, or release readiness are involved.
