What is DECA?

Your AI writes. DECA audits.

DECA is BizPln's deterministic control layer for AI-built software. It independently checks what your AI actually built, shows the gaps in plain language, and keeps humans in control of the approval gates.

DECA documentation and audit surface

The core rule: the system writing the software and the system checking the software stay separate.

Independent audit

Stop letting your AI grade its own homework.

AI builds the product. DECA checks whether what it built is real, accounted for, and still under control.

DECA is not another coding agent. It is the auditor beside the agent. It has no incentive to reassure you, rewrite the story, or call a messy change good enough. It reconciles what was declared against what actually exists and reports the gap.

The ledger metaphor

Double-entry bookkeeping for code.

Debits

Every AI-made change: files, routes, dependencies, generated surfaces, and structural movement.

Credits

The declarations: domain manifests, ownership boundaries, sealed ledgers, and the human-approved intent.

01

Find drift early

Orphan files, undeclared routes, quiet dependency spread, and domain boundaries that no longer balance.

02

Keep evidence

Plain-language reports, quality gates, approval packets, isolation proof, and clean Git handoff evidence.

03

Control spend

Find out if what your AI built holds up while the cracks are still cheap to fix.

Founder friendly

You should not need to read the code to know whether it holds up.

The founder risk is volume without accountability. AI can produce a thousand lines that look plausible and hide the three lines that make the system fragile. DECA makes that hidden structural risk visible before it becomes load-bearing.

What DECA tells you

Verify the structure. Do not sell yourself a vibe.

01

Declared

What the agent said it intended to build and which domain it should touch.

02

Observed

What changed in the actual files, routes, dependencies, and boundaries.

03

Reconciled

Where the two sides balance and where they drift apart.

04

Approved

What is safe to hand off, what needs remediation, and what still needs a real test.

What it proves

  • Structural truth about what AI changed
  • Ownership, route, dependency, and boundary drift
  • Clean audit evidence for approvals and handoffs

What it will not fake

  • Behavioral proof unless real tests ran
  • Business success from structural cleanliness alone
  • A confident answer where evidence is missing
