readiness-gate

Use at every 'are we ready?' moment — before declaring a task done, shipping, demoing, advancing to the next phase, or answering 'so everything works and we're good?'. Replaces vibes-based confidence ('should work now', 'looks good') with an explicit, evidence-backed go/no-go: what was verified and how, what was NOT verified, what changed, and the honest residual risk. Calibrates certainty to evidence — never asserts '100% sure' beyond what was actually tested, and never truncates the findings to fit a tidy summary. Use when reporting completion of any unit of work, when the user asks for a readiness check against a spec or checklist, or when you catch yourself about to say 'this should work'.
