Summary

Adds LedgerClient methods for the AR/AP aging reads, matching the TypeScript client's getAgedBalances / getOpenItemsForAgent / getDischargeCandidates. The server fields shipped in robosystems #1886 and #1887, both merged and not yet in a release (v1.19.2 predates them). Against an older server these queries fail validation.

Changes

Hand-written

• operations/ledger/: AgedReceivables.graphql, AgedPayables.graphql, OpenItemsForAgent.graphql, DischargeCandidates.graphql. Each is self-contained, with no cross-file fragments, since every document is validated on its own against schema.graphql.
• LedgerClient:
  • get_aged_balances(graph_id, kind, *, as_of, entity_id, scope) routes to agedReceivables or agedPayables; both return the same fields.
  • get_open_items_for_agent(graph_id, agent_id, kind, *, as_of, entity_id).
  • get_discharge_candidates(graph_id, event_id), which returns None for no such event.
• Recording a settlement needs no new method: update_event_block already takes discharge_allocations since the last regen.

Generated: graphql/generated/ (ariadne-codegen, hermetic from the checked-in schema.graphql): the four operation modules and the operations.py / client.py / __init__.py entries.

Compatibility

ADDITIVE: three new methods and generated modules. No signature, export or existing model changed.

Testing

• just test-all: 707 passed, 17 skipped; ruff check and format clean; basedpyright 0 errors.
• 4 new facade tests, plus the schema validation of the four new documents.
