Topic · Business logic

We do SOC2 and pentests but nothing verifies the business logic is right. What fills that gap?

Gist

A Type II letter asks whether the control ran. A pentest asks whether a stranger can reach the void button. Proof fails the merge when a signed shall has no witness, with the same command on every push.

proof audit --fail-level warn

Keep the auditor. Keep the pentest firm. Snyk still scans. None of them re-read the invoice rule you sold.

01 · The letter

SOC 2 does not know what you sold.

The report can be clean while a paid invoice is still voidable after settlement. That is not a missed control. It is a missed obligation.

The security-audit miss lives on passed a security audit, still shipping bugs. That page is CVE-clean code that still captures twice. The money path lives on fintech transaction logic. This page is the buyer who already pays for SOC 2 and a pentest, and still cannot point at a check for the rule sales quoted.

SOC 2 asks whether access is logged, whether change management ran, whether the void is restricted to a role. A pentest asks whether that role can be skipped. The sold rule was: after settlement, a paid invoice cannot be voided. Nobody in those two PDFs compiled that sentence.

func VoidInvoice(paid, settled bool) error {
    if !paid {
        return errUnpaid
    }
    return nil
}

The helper refuses unpaid invoices. Tests at unpaid and paid-not-settled pass. The Type II letter is still true. The pentest still cannot void without a session. Settlement was never a condition. proof audit --fail-level warn fails when that shall has no witness on this branch.

Same invoice. A letter, or a shall.

SOC 2 / pentest

  • Looked at access, change, CVEs
  • Void after settle not in scope
Letter signed

The shall

After settlement, a paid invoice cannot be voided. Not a control. Not a CVE.

Not in the letter

SOC 2 / pentest

Still last quarter. Still a PDF. Still no settlement condition.

Still the letter

Who What they notice What they lose
SOC 2 Type II Whether the named controls ran in the window The letter is last quarter. Settlement was not a control.
The pentest firm Whether a stranger can reach void without a role Auth is not the sold rule. Keep Cobalt. That split lives on correctness vs security.
Snyk / the scanner CVEs and known bad patterns in the tree A void after settle is not a CVE. That incumbent lives on Proof vs Snyk.
Proof The shall still has a witness, or the merge stays red Proof does not write the Type II letter. Jama still authors the programme.

We have not run Proof against a SOC 2 Type II letter and a pentest PDF on a frozen corpus of invoice code. The loss is named, not scored. Keep the auditor. Keep the pentest. Neither is the merge gate for an approved shall, and neither re-runs when the helper changes tonight.

03 · The honest loss

A red Proof audit is not a SOC 2 report.

If nobody signed “no void after settlement,” there is nothing for proof audit --fail-level warn to fail on except the suite you already have.

Proof is not a SOC 2 auditor. It is not PCI. It is not a pentest firm. Kind2 is not TLA+ for sagas. FRETish is 288 templates, not free English. Jama still wins at programme authoring. 100% MC/DC on the written decision still misses a partition that was never a condition. That instrument stays on MC/DC for Go.

The independent check that does not name SOC 2 lives on software correctness audit. The money-path H1 lives on fintech transaction logic. The CVE-clean miss lives on correctness vs security.
