// v0.41 T4 — bundled lens pack manifest smoke tests.
//
// One test file covers all 4 packs (creator, investor, engineer, everything)
// because each test boils down to "manifest parses + declares the expected
// shape." Splitting per-pack would 4x the boilerplate without adding signal.
//
// Pinned contracts:
//   - All 4 YAMLs parse via parseSchemaPackManifest without error
//   - Each pack registered in BUNDLED (loadPackManifestByName resolves)
//   - Each pack declares the expected page_types, phases, calibration_domains
//   - extends chain resolves through registry without depth error
//   - gbrain-everything unions all three lens packs' contributions
//   - Calibration domain aggregator is the closed AggregatorKind enum on every entry
