// Package main: from_pubkey backfill shim (issue #1287).
//
// The actual backfill moved to cmd/ingestor (see
// cmd/ingestor/maintenance.go: BackfillFromPubkey) because the server
// is the read path and may not write to SQLite (#1283/#1287). This
// file retains the snapshot getter so /api/healthz still compiles —
// it always reports done=true with zero counters. Operators monitor
// the ingestor's stats file for true progress.
