What it is for

Manual N-line balanced journal-entry write API over the domain-ledger schema, gated by application-rbac UserPermissions.

Routes (mount under the host's admin prefix, e.g. /api/v1/admin):

POST /ledger/entries gated PERM_WRITE — create draft|posted
GET /ledger/entries/{id} gated PERM_READ — fetch entry + lines
PATCH /ledger/entries/{id} gated PERM_WRITE — edit a DRAFT (header

and/or lines); may also post it (status:"posted"). Posted → 409.

DELETE /ledger/entries/{id} gated PERM_WRITE — delete a DRAFT.

Posted → 409 (corrections are reversals; INV-1).

Posting is enforced twice: a friendly service-level balance check (Gate 1.5 A3) and the DB journal_entries_check_balance trigger as the backstop. All entry kinds share one shape + a kind tag (Gate 1.5 A2); drafts may be unbalanced/incomplete (Gate 1.5 B4), only posting requires balance.

`ReverseOutcome`

Manual N-line balanced journal-entry write API over the domain-ledger

Item
`pub enum ReverseOutcome`
`async fn reverse_in_tx(tx : & mut sqlx::Transaction <'_, sqlx::Postgres>, tenant_id : Uuid, original_id : Uuid, reversal_date : Option <& str>, memo : Option <& str>,) -> Result <ReverseOutcome, sqlx::Error>`

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`

Item	What it is
`pub const PERM_READ: & str`	Permission to read journal entries.
`pub const PERM_WRITE: & str`	Permission to write (create/edit/delete/post) journal entries.
`pub const PERM_REVERSE: & str`	Dedicated permission to reverse (void) a posted entry
`pub const PERM_SETTINGS_WRITE: & str`	Permission to change the ledger org settings (the reversal policy)
`fn router <S>() -> Router <S> where S : Clone + Send + Sync + 'static, PgPool : FromRef <S>,`	Build the journal-entry write sub-router.
`pub enum ReverseOutcome`	Outcome of `reverse_in_tx`.
`async fn reverse_in_tx(tx : & mut sqlx::Transaction <'_, sqlx::Postgres>, tenant_id : Uuid, original_id : Uuid, reversal_date : Option <& str>, memo : Option <& str>,) -> Result <ReverseOutcome, sqlx::Error>`	Reverse a posted entry inside an existing transaction: lock it (`FOR UPDATE`), require posted + not-already-reversed, insert a balanced reversing entry (lines swapped), post it, and set `reversed_by_id`

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

Boundary

Reaches into domain.

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

Kind	Name	Source
lib	`application_ledger_entries`	`src/lib.rs`

Error model

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

Operational characteristics

Property	Evidence
async public surface	yes
async runtime	none detected
database access	yes
network I/O	yes
unsafe code	none detected
environment variables	none detected

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.

No workspace crate depends on this one.
