Rewrite vs Harden Checklist — Layer Gates Before You Scrap or Stay

You do not need a manifesto to decide rewrite vs harden—you need pass/fail gates per layer. This lander is the short operator list: score UI DNA, data, auth, secrets/env, host/CI, and store compliance, then pick harden-in-place, one bounded rewrite, or full extract. It is not Article 6’s longform matrix; it is the clipboard you run in one working session before you burn a sprint on the wrong path.

CodeCross LLC’s rewrite-vs-harden checklist is a layer-by-layer go/no-go for vibe and AI-builder products: harden when UX converts and gaps are fixable; bound a rewrite to one failing layer; extract when builds, secrets, or runtime cannot be reproduced outside the builder. Intent is operator decision gates—not a Softgen/v0 FAQ paste and not a clone of `/articles/rewrite-vs-harden-after-ai-builder-2026`. Pair the article for depth; use this page for the scored list.

What this clipboard is for

A layer scorecard, not a pride rewrite

Founders burn sprints redrawing screens that already convert, or they polish a layer that cannot be reproduced outside the builder. Mark each layer once, then sequence the worst red.

  • UI DNA is not the whole product

    If the surface converts, that is evidence to keep—not a reason to skip data, auth, or host scores. A pretty path can still be unowned.

  • One red layer is not “rewrite everything”

    Client-only auth or an unreproducible deploy is a bounded rewrite. Serial band-aids across three failing ownership layers is extract.

  • Missing evidence is a path change

    If you cannot tag a build, vault secrets, smoke the domain, and name rollback in week one, harden-in-place is wishful. Pivot.

  • The essay is not the clipboard

    Article 6 explains the 2026 matrix. This page is what you mark green or red today. Do not copy the article’s H2s into the scorecard.

The session

Inventory, score, pick, then prove week one

Run this in one working block. The deliverable is six marks and a sequenced first layer—not a slide deck.

01

Inventory the six layers

UI DNA, data (schema + restore), auth (server-side proof), secrets/env (org vault), host/CI (reproducible artifact), and store/compliance if you ship binaries.

02

Mark harden / bound / extract on each

Harden when the base is sound and gaps are controls. Bound a rewrite when that layer is unreproducible or unsafe. Extract when ownership cannot be recovered in place.

03

Sequence the worst red first

Do not start with cosmetic UI. The cheapest wrong path is rewriting converting screens while host or auth still fail.

04

Demand week-one evidence for harden

Tagged build outside the preview, secrets only in org env, critical-path smoke on your domain, named rollback owner. No evidence, change the mark.

How to

Score rewrite vs harden in one working session

A layer clipboard. Success is six marks and a sequenced first gate—not a manifesto.

  1. Step 01

    List the six layers as they exist today

    UI DNA, data, auth, secrets/env, host/CI, and store/compliance if you ship binaries. Write what you can prove, not what you intend.

  2. Step 02

    Mark each layer harden, bound rewrite, or extract

    Harden when UX converts and the gap is a control. Bound a rewrite when the layer is unreproducible or unsafe. Extract when three or more layers fail ownership.

  3. Step 03

    Sequence the worst red layer first

    Do not polish converting screens while auth, data rules, or host/CI stay red. One failing ownership hole beats a vanity rebuild.

  4. Step 04

    Prove harden with week-one evidence

    Tagged build outside the builder preview, org-controlled secrets, one critical-path smoke on your domain, and a named rollback owner.

  5. Step 05

    Open Article 6 only for depth

    Use the longform matrix when a mark is ambiguous. Keep this page as the scored list. Next operator pass is often the production audit.

Which six layers get a harden / bound / extract score first?

Score UI DNA (does the surface convert?), data (owned schema + restore?), auth (server-side proof?), secrets/env (org vault, not chat history?), host/CI (reproducible artifact?), and store/compliance if you ship binaries. CodeCross LLC marks each as harden-in-place, bounded rewrite, or extract—then sequences the worst layer first so you do not “rewrite everything” by default.

When does a single red layer force a bounded rewrite instead of polish?

When the layer is unreproducible or unsafe under traffic—e.g. auth only lives in client flags, database rules deny-open, or deploys cannot roll back—and a patch would leave the same ownership hole. Harden fixes controls on a sound base; a bounded rewrite replaces that one failing layer while keeping converting screens. If three or more layers fail ownership, plan extract instead of serial band-aids.

What week-one evidence proves you picked harden over extract correctly?

A tagged build outside the builder preview, secrets only in org-controlled env, one critical-path smoke on your domain, and a named rollback owner. If you cannot produce that evidence without the builder’s hosted runtime, harden-in-place is wishful—pivot to extract or a bounded host/CI rewrite. CodeCross LLC treats missing evidence as a path change, not a longer polish list.

How should founders use this checklist next to Article 6?

Article 6 teaches the 2026 decision matrix in depth (`/articles/rewrite-vs-harden-after-ai-builder-2026`). This lander is the scored clipboard: inventory → score six layers → pick path → week-one gates. Read the article for why; run this checklist for what to mark green/red today. Cross-link `/vibe-coding/production-audit` when the next step is a pre-traffic pass, not a rewrite debate.

Mark the layers before you burn the sprint.

Bring the preview and what you can already prove. We will score the six layers — or tell you the mark is already obvious.
