Start with the behavior

Use the simulator to post operational events, inspect balanced entries, trace wallet movement, and observe reversal-based corrections.

Choose the depth appropriate to your review.

Evidence-based assessment of current posting behavior, schema constraints, risks, and rebuild recommendations.

Current-system evidenceAudit

Open Report

Table-by-table proposal for financial events, posting requests, immutable transactions, entries, wallet operations, and migration lineage.

Proposed designSchema

Open Schema

Run invoices, payments, bills, POS sales, journals, transfers, and reversals through the proposed posting model.

PrototypeInteractive

Open Simulator

Explains the controls, expected effects, accounting rules, evidence labels, unresolved alternatives, and review boundaries.

Reviewer guideBehavior notes

Open Manual

The artifacts build on one another.

1. Audit

Establish what the current API and database actually do.

2. Model

Inspect the proposed posting contract and storage boundaries.

3. Simulate

Test financial events, state changes, entries, and reversals.

4. Characterize

Resolve open choices before migration specifications and implementation tickets.

What each source can legitimately establish.

Source	Baseline	Used for	Not proof of
Product API	`Built-Accounting/simple`, `master`, `1ce2358f`	Implemented posting paths, mutations, feature ownership, and reporting queries reviewed during the second-pass audit.	Production data quality, undocumented operational practice, or confirmation that the reviewed commit is the exact production deployment.
Application migrations	Migration files in the clean `Built-Accounting/simple` clone at `1ce2358f`	Second-pass evidence for intended table evolution, feature-specific ledger links, declared foreign keys, and schema changes created after the export.	Confirmation that every migration ran successfully in every live environment or that live constraints still match migration intent.
Database export	`current_db_schema_export_2026-05-18_13-39.sql`	Point-in-time evidence for tables, columns, indexes, keys, and database-level protections, cross-checked against the later application migrations.	Later schema changes, every runtime invariant, or the complete current production schema.
Simulator model	Logical proposal `v0.2`	Target behavior, design discussion, migration planning, and reviewer feedback.	Approved architecture or production implementation.
