plumb-line

Use when setting up a project with the plumb-line discipline — interviews the builder to find their source-truth layer and layering, generates a domain-neutral ruleset, and installs parameterized enforcement (boundary check, test gate, pre-commit gate, branch guard) for the project's language. Ships no default layers and invents no answers.

Use when a builder wants to learn or be reminded of the plumb-line method — the discipline of epistemic honesty enforced by tooling. Teaches the thesis, the nine portable principles, the maturity vocabulary, and the one-line test. Pure knowledge; takes no actions.

Use when auditing a diff or repository against the plumb-line principles — finds laundered uncertainty, boundary leaks, hardcoded priors, overstated maturity, outputs lacking recorded lineage, and baseline drift with no explanation. Read-only: it reports, never auto-fixes.

Use when applying findings from a plumb-line audit report — the builder has a report (or pasted findings) and wants the fixes made. Opt-in and separate from the audit, which is read-only and never fixes.
