Multi-step executors (match_transaction_invoice, credit_invoice) post an irreversible voucher or persist a credit note and then run later fallible steps. A failure there previously marked the whole op status=rejected, hiding the posted entity and its id from operators. - new migration 20260722134114: add failed_partial to the pending_operations status CHECK and treat it as terminal in both immutability triggers (immutable, undeletable, never re-claimable) - PartialCommitError + ExecutorResult.partialPostedIds carry the posted ids; the dispatcher writes status=failed_partial with result_data.posted_ids and returns code=partial_commit - instrument only the two named executors; hoist the read-only settlement-account resolution above the storno in the match executor - consumer sweep: status union + query schema widened, failed_partial folds into the Avvisade tab with a badge and posted-ids detail line, bulk/reject routes and MCP tools message it explicitly, worklist and expiry sweep intentionally untouched (not pending work) - tests: pg-real coverage for the new terminal semantics, dispatcher unit tests for both partial paths plus byte-for-byte regression guards Fixes #842 Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
