Every row is confirmed commerce. Every record is immutable. The asterisk flags open obligations. The total must match the invoice — or the ingestion is invalid. That's not a feature. That's the law.

Act
01
No Overwrite
Records are permanent. Corrections append as new rows. History is preserved, not obscured. The ledger only grows forward.
02
Invoice Is Truth
Only confirmed invoice lines become memory. PO intent is not stored. Notes, constraints, and packaging rules do not enter the ledger. Signal only.
03
Totals Must Match
The sum of every extended_price must equal the invoice total before ingestion is valid. Mismatch means no commit. The integrity check is not optional.
04
Drift Visible By Design
Price changes, catalog number changes, substitutions, and backorder patterns surface naturally as new rows against old history. No report needed. Drift is visible because history is preserved.
05
AI Reads, Doesn't Guess
Clean, governed signal means AI operates on preserved reality — not inferred context. No hallucination. No normalization distortion. The ledger is the source of truth.
06
No Infrastructure
Runs as Excel, JSON, or HTML. No backend. No database. No integration required. The file is the transport. The law is the governance.

FAQ
Frequently Asked Questions
01
What Is SIGNAL LEDGER?
SIGNAL LEDGER is an append-only commercial ledger that turns vendor invoices and purchase orders into trusted, traceable memory for pricing history, SKU mapping, backorder tracking, drift detection, and AI-ready intelligence.
02
Does It Replace ERP?
No. SIGNAL LEDGER does not replace ERP or accounting software. It sits above existing systems as a governed signal layer that makes commercial data trustworthy without replacing the systems that use it.
03
Can It Detect Drift?
Yes. Because the ledger is append-only, price changes, catalog changes, substitutions, and backorder patterns become visible across vendor cycles with no configuration required.
04
Does It Need A Backend?
No. SIGNAL LEDGER runs as Excel, HTML, or JSON with no database, no backend, and no infrastructure requirement. The file is the transport. The law is the governance.
05
Can AI Use The Data?
Yes. SIGNAL LEDGER preserves governed, traceable commercial signal so AI can read trusted data instead of guessing from distorted or incomplete system output. No hallucination. No normalization distortion.
