Notes

gobank is the top-level model bank simulation, depending on the companion libraries below.
gobank-products defines the product catalogue (savings, loans) and simulation engine.
gobank-accounts provides chart of accounts, P&L, balance sheet, and accounting period management.
gobank-workflow orchestrates daily tasks (interest accrual, EOD processing) via go-workflows.
gobank-db abstracts the database layer — shared schema, migrations, multi-service base.
gobanks-customers handles customer identity with encrypted PII storage.
go-postgres wraps modernc.org/sqlite to provide a pglike interface — pure Go, no CGo.
gotreesitter is a pure-Go tree-sitter runtime used by go-luca and plain-text-accounting-formats for parsing PTA syntax.
tree-sitter-goluca is the grammar definition (JS/node); tree-sitter2abnf converts it to ABNF for documentation.
lofigui is the HTML/CSS UI framework used by gobank (demo submodule) and task-plus.
task-plus manages the release workflow for projects that include a task-plus.yml.
Dashed lines in the graph indicate non-Go tooling relationships (code generation, grammar definitions, release management).
