Run a reconciliation

Match a snapshot of external items against unreconciled postings. Matching is per-currency, per-amount, with a default 24-hour value_date window. Optional account_id on each item narrows the candidate pool.

The response surfaces three sets: matched, unmatched_external (items we couldn’t pair), and unmatched_internal (postings in the time window that no external item claimed; only populated when from/to bound the query).

Idempotent: matched postings get marked once. Items are stored as external transactions keyed by (source, external_id). Re-running the same snapshot reports already-matched items in matched with their original attribution; nothing is double-marked.

Items may carry reference_rail, reference_kind, and reference_value (all three or none). When the triple resolves to a transaction external ref, that posting is matched first with strategy external_ref (exact amount required).

enum<string>

default:exact

Matching strategy. exact pairs an external row with at most one posting (default, pre-existing behavior). sum_in_window pairs an external row with a subset of up to five postings whose summed amount equals the external amount within auto_resolve_below_minor_units, with every posting in the subset inside +/- window_seconds of the external row's at.

Available options:

exact,

sum_in_window

auto_resolve_below_minor_units

default:0

Absolute minor-unit tolerance budget for auto-resolving small breaks. Accepts a decimal string (recommended) or an integer on write; returned as a string. A match whose |sum(postings) - external_amount| residual is <= this value is treated as matched and emits reconciliation.break_auto_resolved. Default "0" = strictly equal.
