application-ledger-reports

Generic double-entry ledger read-only report routers (register, GL, trial balance, income statement, balance sheet, search) over the domain-ledger schema.

What it is for

Generic double-entry ledger reports: read-only API routers computed over the domain-ledger schema (accounts / journal_entries / line_items).

Lifted from the books app (server/src/ledger_reports.rs). All endpoints are gated by application_rbac::authz::UserPermissions::has(PERM_READ) and operate over posted entries only, signing balances by account_type (debit-normal = asset/expense; credit-normal = liability/equity/ income) — no normal_side column required. Mount router under whatever admin/auth prefix injects the UserPermissions extension.

Endpoints (relative paths)

• GET /ledger/accounts/:code?from=&to= — per-account register / drill-down

with a DB-side running balance and an optional opening balance-forward.

• GET /ledger/reports/general-ledger?from=&to=&account= — all posted lines

grouped by account with per-account running balances + subtotals.

• GET /ledger/reports/trial-balance?as_of= — as-of signed balances placed in

their natural debit/credit columns, with a balanced check.

• GET /ledger/reports/income-statement?from=&to= — income/expense period

totals + net income.

• GET /ledger/reports/balance-sheet?as_of= — assets/liabilities/equity with

a synthetic "Net income (unclosed)" equity line so the sheet ties mid-year.

• GET /ledger/search?q=&from=&to=&account=&dir=&limit= — global transaction

search over posted lines (ILIKE on description and journal_entries.payee).

Schema note: journal_entries.payee

search filters and returns journal_entries.payee (a standard generic ledger concept). The base ledger migration (crates/domain/ledger/migrations/001_ledger_tables.sql) declares it as a plain nullable text column; consumers get it for free.

How to use it

No examples/ target and no doctest in this crate's rustdoc. The tests listed under Verification are the closest executable usage.

Module structure

No public modules: the crate root is its whole surface.

Public surface

`crate root`

No pub use re-exports: every item above is declared in this crate.

Boundary

Depends on no other workspace tier.

Shares tier application with 120 other crates: application-agreements, application-ai, application-analytics, application-approvals, application-assessments, application-audit-log, application-auth, application-billing, … (120 total).

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._

Feature flags

No Cargo features are defined: every capability is unconditional, so no consumer can receive a half-wired crate.

Targets

Error model

No public error type was detected: no public item declares a type named *Error, and no public signature returns one.

Operational characteristics

No unsafe block, unsafe fn, unsafe impl or unsafe trait was found by the parser anywhere in this crate's source.

Configuration

No environment variable is read with a literal name anywhere in this crate. A variable whose key is computed at run time cannot be listed here, and is not claimed to be absent.

Related capabilities

No workspace crate depends on this one.

Verification

Evidence by module. How often each public module is named by something executable.
