// Package autonumberseed holds the pure, backend-free autonumber-seed DTOs,
// the declared-seed key, the LegacySource enum strings, and the
// BuildScopeSourceMapFromSeeds translator — relocated out of internal/bootstrap
// as the Wave-0 SLICE B slice of the bootstrap-decoupling campaign.
//
// Everything here is stdlib-only. The DB-driven seed runner
// (SeedAutoNumberCounters) and the V1-V8 verify gate
// (VerifyAutoNumberInvariants) read the live DB and remain in
// internal/bootstrap as behavioral/port symbols.
package autonumberseed

// AutoNumberFormatSeed mirrors packs.AutoNumberFormatSeed but lives in
// the bootstrap package so SeedAutoNumberCounters does not create a
// packs → bootstrap → packs import cycle (packs already depends on
// bootstrap for ReconcileTableColumns / InitializeFieldMappings).
//
// L0 platform seeds and app-pack wire-up code construct this slice through the
// controlplane/packs shim; tests in this package build it directly.
