We added a hash of the diff and the untracked source files, and a test that edits, adds and reverts.https://sites.zyp2.gig-io.com/blog/when-git-cannot-answer-rebuild/https://sites.zyp2.gig-io.com/blog/when-git-cannot-answer-rebuild/Thu, 22 Oct 2026 00:00:00 GMTA fingerprint that falls back to a plain string when git fails can match a stored release. We made an unknown fingerprint read stale and force a rebuild, and wrote tests for both outcomes.https://sites.zyp2.gig-io.com/blog/hand-the-designer-what-ships/https://sites.zyp2.gig-io.com/blog/hand-the-designer-what-ships/Tue, 20 Oct 2026 00:00:00 GMTWhen a design tool needs to show your pages, export the build's own resolved output, not your templates and content. A versioned, deterministic directory of exactly what ships is the only preview that cannot drift from the site.https://sites.zyp2.gig-io.com/blog/preview-with-the-gates-own-code/https://sites.zyp2.gig-io.com/blog/preview-with-the-gates-own-code/Fri, 16 Oct 2026 00:00:00 GMTA preview that estimates what the gate will do is a second implementation of the gate, and it will drift. Make the preview call the gate's own function, so a clean preview is the build passing.https://sites.zyp2.gig-io.com/blog/the-default-that-failed-open/https://sites.zyp2.gig-io.com/blog/the-default-that-failed-open/Fri, 16 Oct 2026 00:00:00 GMTAn optional argument with a safe-looking default is a guard that a forgetful caller can skip. For anything that protects a boundary, make the argument required and let the compiler refuse the caller.https://sites.zyp2.gig-io.com/blog/two-seats-per-task/https://sites.zyp2.gig-io.com/blog/two-seats-per-task/Thu, 15 Oct 2026 00:00:00 GMTOne agent builds each task and a fresh one reviews it before the next task starts; one scoped re-review per fix; one whole-branch review at the end. The shape matters more than the model.https://sites.zyp2.gig-io.com/blog/a-plan-the-next-session-can-run/https://sites.zyp2.gig-io.com/blog/a-plan-the-next-session-can-run/Tue, 13 Oct 2026 00:00:00 GMTAn implementation plan written for an agent with no memory of the design conversation needs exact code in every step, a brief per task and a ledger that outlives the session.https://sites.zyp2.gig-io.com/blog/refuse-dont-warn/https://sites.zyp2.gig-io.com/blog/refuse-dont-warn/Thu, 08 Oct 2026 00:00:00 GMTA build that warns about a leak will ship the leak. Make every check a refusal with a name, prove each one with a red case first, and let the build fail closed.
