Tested with 31 script tests, a real six-month general ledger export, and two rounds of end-to-end runs by a fresh Claude agent with only the skill file and the raw export. The changes from the second round and from a code review (13 issues) are covered by the script tests, not yet by a fresh end-to-end run. Not yet tested: a run inside the Claude apps, and the connected path against the live Cybooks connector.
