These are Thorbis applications and review exercises, not replacements for DESIGN.md, COMPONENTS.md, or the owning skill. Linear remains the operational baseline. External advice that conflicts with the constitution stays out. These worked examples are not a claim that the product behaviors have been implemented or verified. ### Close the loop with evidence, not the word polished Owning skill: [tracking](https://design.thorbis.com/skills/tracking). Vague design requests produce repeated subjective revisions and hide which parts of the result were actually checked. A review records the person and task, the observed defect, the owning rule, the smallest correction, and its verification. Preserve source access limits. Turn repeated feedback into a better existing default rather than another detached instruction file. **Thorbis example:** Instead of make the button premium, record that its pending state moves the label, identify the UI owner, compare the corrected state under the same content, and attach the relevant checks and remaining uncertainty. **Verify:** Separate a source that was read from a demo that was exercised. Separate a passing content test from a browser check, and a committed branch from a deployed release. Report failed and skipped checks explicitly. **Do not import:** No fabricated research, inferred paid lesson content, unmeasured uplift claim, or declaring work live because a commit exists.
