Decision gates · Not a scrap pile

Should you rewrite — or harden what you have?

Scrap everything feels brave. It is often waste. This checklist scores each layer — UI, Auth, data, jobs, host, secrets — as harden, bound-rewrite, or extract. Keep what works. Rebuild only the red layer. Longform depth lives in the article; this page is the clipboard.

In plain words

Answer you can cite

Rewrite versus harden is a layer score, not a vibe. Mark UI, Auth, data, jobs, host, and secrets: wrap in place, rebuild one bounded slice, or extract. You keep working DNA. You only pay to rebuild what stranger tests prove unsafe. The article explains why — this page marks the boxes.

Where scrap-or-stay goes wrong

People rewrite screens that already sell

Vanity rewrites burn the demo. Blind polish on a broken Auth model burns customers. Score layers.

  • Rewriting UI because prompts feel messy

    If stranger journeys pass, harden UI chrome — do not redraw unsold screens.

  • Polishing a broken Auth or tenancy model

    One red identity layer forces a bounded rewrite before ads.

  • No week-one evidence plan

    Decide from tests: cold Auth, record boundaries, restore drill — not taste.

  • Using this page as Article 6

    Article 6 is the longform. This checklist is the clipboard you mark today.

The layer walk

Mark six layers, then pick one move

One red layer gets a bounded plan. Green layers stay.

01

List six layers in your stack

UI, Auth, data, jobs, host, secrets — rename to fit.

02

Score harden / bound / extract each

Harden = wrap. Bound = rebuild that slice. Extract = move off the builder.

03

Demand week-one evidence for harden picks

Stranger Auth, object-level access, restore, kill switch.

04

Time-box any bound rewrite

One slice, one owner, one done check — no scrap-the-world sprint.

How to

How to score rewrite vs harden this week

Clipboard first. Essay later.

  1. Step 01

    Write the six layers

    UI, Auth, data, jobs, host, secrets.

  2. Step 02

    Mark each harden, bound, or extract

    Use stranger-test evidence, not taste.

  3. Step 03

    If mostly harden, open MVP hardening

    Wrap week on the public surface.

  4. Step 04

    If one red core layer, plan a bound rewrite

    Keep green layers intact.

  5. Step 05

    If ownership itself is red, open exit

    Keys before cancel.

Practical answers

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

UI, Auth, data, background jobs, host/deploy, and secrets. Score each from stranger tests — not from how tidy prompts look.

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

When Auth, tenancy, or data integrity fails stranger tests and cannot be wrapped with config. Rebuild that slice; keep green UI and host DNA.

What week-one evidence proves harden was the right call?

Stranger accounts pass primary journeys; object-level access denies cross-tenant reads; restore drill works; you can kill a bad release without regenerating.
