break-trace

Root-cause a break Given a single break row (key, GL values, subledger values, bucket, likely cause), trace it to source and produce a root-cause statement. Trace path Pull the GL side — via the internal-gl MCP, fetch the journal entry or posting that produced this GL line: entry id, posting date, source system, batch id, preparer. Pull the subledger side — via the subledger MCP, fetch the matching transaction: trade id, trade/settle dates, counterparty, source feed, FX rate used. Diff the attributes — line up posting date, FX rate/date, account mapping, quantity sign, amount sign. The differing attribute is usually the cause. Cause → statement Write the root cause as a single sentence in the form "⟨side⟩ ⟨did what⟩ because ⟨reason⟩" , e.g.: "GL posted on settle date (T+2) while subledger posted on trade date — timing break, will clear on 2026-05-07." "Subledger used WM/R 4pm rate; GL used Bloomberg close — FX break of 12 bps on the base amount." "Security ABC123 maps to GL account 11420 in the mapping table but the subledger fed 11410 — mapping break, raise to reference-data." "Subledger posted the trade twice (trade ids 88412 and 88419 are duplicates) — duplicate post, suppress 88419."
