Event replay → SQLite projection pipeline.

The Projector replays events from the TSJSON event log and upserts the resulting state into the SQLite projection database. It handles all 11 event types and supports both incremental (single-event) and full rebuild modes.

Deduplication

Events are deduplicated by event_hash. When a duplicate hash is encountered (e.g. from git merge duplicating lines in shard files), the event is silently skipped.

Cursor

After projecting a batch, the caller can persist the byte offset and last event hash via super::query::update_projection_cursor for incremental replay on next startup.

Structs

ProjectionStats

Statistics returned after a projection run.

Projector

Replays events into the SQLite projection.

Constants

PROJECTED_EVENTS_DDL

SQL to create the projected_events tracking table.

Functions

clear_projection

Drop all projection data for a full rebuild.

ensure_tracking_table

Ensure the projected_events tracking table exists.
