// Package packs — bootstrap_shim.go exposes the platform
// AutoNumberFormatSeeds slice to callers in the bootstrap domain without
// creating a packs → bootstrap → packs import cycle (packs already
// imports bootstrap for ReconcileTableColumns / InitializeFieldMappings).
//
// The `packs.AutoNumberFormatSeed` struct and the domain
// `bootstrap.AutoNumberFormatSeed` struct are wire-identical but live in
// separate packages. This shim performs the one-line copy, preserving
// the F8 `LegacySource` column that earlier Lane-D wire-ups dropped.
//
// Round-5 Codex V1-P1 / V2-C1: the previous phase5 path used
// `loadAutoNumberSeedsFromDB` which read only 5 columns and silently
// defaulted `LegacySource` to `"none"`. That made scope-aware GREATEST
// fall back to `max(live+1, start)` for every seed, ignoring the
// legacy `_System_AutoNumber.CurrentNumber` and
// `_System_CompoundAutoNumber.CurrentNumber` floors. On cutover this
// would silently re-issue already-used identifiers.
