Selective package and CLI initialization

Three alternating fresh-process pairs per command retain the complete CLI:

Command Prior s Selective s Speedup
Top-level help 1.970183 0.547647 3.597543x
Artifact validation 1.856774 1.187515 1.563580x
Complete probabilistic refinement 2.486135 2.145332 1.158858x

This improves startup, especially light commands. The full refinement gain is modest; it is not presented as a large numerical or GPU acceleration. All 18 complete outputs and six complete calibration artifacts/traces match. All 164 parser routes, 1,257 recorded argument actions, help, defaults, choices and all 129 public schemas plus their ledger remain identical.

The prepared execution control uses nine public KITTI scans with 1,024 points per frame (9,216 rows). Image correspondences are generated projections, without independent accuracy evidence. The compressed correspondence input retains its exact uncompressed protocol hash. Original scan hashes and fixture construction metadata are in fixture-protocol.json and the input provenance. Raw scan registration and control generation are outside these timings.

This archive includes all prepared inputs, actual source identities, full source capsules/manifests, every timing/stdout/stderr/import record and result, complete parser snapshots, schema parity receipts, source/checker pins and validation receipts. index.json binds every publication byte other than itself. Earlier package-only and pre-guard cohorts remain identified, with all their timings and hashes in validation/cohort-selection.json. Only the final v3 cohort supplies the speed claims above.
