# Location significance backfill

Reassesses an existing book's persisted location review using saved scene analysis. No AI calls, canonical location changes, decision resets, or candidate regeneration.

1. Apply `PlotLine/Sql/192_LocationNarrativeSignificance.sql`.
2. Build this project.
3. Supply `PLOT_DIRECTOR_SQL_CONNECTION` securely and run the DLL with `<bookId> <userId> <expectedDatabaseName>` for a dry run.
4. Review the match/classification counts, then repeat with `--apply`.

The user must have access to the book. All persisted stable keys must match before any assessment is written. Run after analysis finishes. Both commands use stored procedures and the normal contextual resolver. See [design notes](../../docs/location-significance.md) for scoring and limitations.
