Agents grabbed the wrong id when list rows exposed a bare 'id' next to
qualified ids (journal_entry_id) with no type distinction, got
NOT_FOUND, and had to re-derive (agent.feedback).
Additive sweep of all 11 bare-id sites: every output identifier now
ships a fully qualified sibling (transaction_id, fact_id, atom_id,
company_id, dimension_id, dimension_value_id); the bare 'id' stays as
a deprecated alias for compatibility.
New ratchet test (qualified-ids.test.ts): a shrinking grandfathered
list carries the deprecated aliases; any NEW bare 'id' in an output
schema fails CI, every remaining alias must ship alongside its
qualified sibling, and stale grandfather entries must be pruned.
Convention documented in .claude/rules/mcp-server.md.
Full unit suite: 6,577 green.
Part of dev_docs/mcp_optimization_plan.md (P1-2).
