Apply libs.parser.event_type_normalizer (added in commit 722e5cf) to
existing events whose parser_version LIKE 'oracle-fallback%' so historical
rows match the forward-going normalization wired into the parser.
Implementation:
- New renormalize_oracle_fallback_events() in apps/pipeline/event_parser/main.py
- SELECT filter Event.parser_version.like("oracle-fallback%") — broader
than a hardcoded IN list, so already-aligned values skip naturally and
future additions to _ORACLE_TO_STRATEGY get picked up automatically
- New --renormalize-oracle-fallback CLI flag, chainable with --reparse
- JobRun row written (job_name=event_parser_renormalize_oracle)
- Per-row renormalize_event_updated INFO log + final renormalize_done
summary with transition counters
Live DB run: seen=2937 / updated=1069 / skipped=1868 / errors=0.
Wall ~2 sec (pure DB UPDATEs, no Oracle calls).
Transitions:
earnings_result -> earnings_release : 412
shareholder_vote -> other_material_event : 409
regulation_fd -> guidance_update : 237
acquisition_disposition -> other_material_event : 7
other -> other_material_event : 4
Unmapped Oracle values (financial_obligation 225, articles_amendment 81,
contract_termination 48, etc.) preserved verbatim — honest filter-drop.
Stale-by-design (mirrors existing reparse_events convention):
- Event.event_id PK still embeds old raw event_type substring
- EventParse.output_json["event_type"] still carries raw Oracle value
Strategies read Event.event_type, not those fields. Avoids cascading
PK rewrites across event_parses/feature_snapshots/event_labels tables.
Integration test: tests/integration/test_renormalize_oracle_fallback.py
inserts 4 fixtures, drives _apply_oracle_renormalization() against the
rolled-back db_session, asserts updated/skipped/error counts and final
row state.
Snapshot rebuild not run — nightly auto-rebuild picks up normalized
values incrementally.
