Chiki Bum	0d5ca3c197	P3-DATA-ENGINE-002: Data Engine v1 implementation + qualification suite (QUALIFIED) ... Implements the frozen P3_DATA_ENGINE_V1_SPEC (SHA 84bf0f217ffba51197112a6bbacbcc297058e04b5ca47f0459028fe33e0321e5). Components: engine/ producer (certify, chunkmap, parse, canonical, worker, dispatcher, aggregate, storage, journal, checkpoint, lock, evidence, manifest, run_complete, dataset_builder, cli) + engine/verify independent verifier (vparse, vaggregate, vinvariants, vcompare); headless CLI sniper-data; golden corpus G01-G17; unit/property/adversarial/mutation/legacy-diff/CLI suites. Qualification verdict: QUALIFIED (all 9 mandatory gates pass; independent verifier accepted). Spec, governance record, and legacy checkpoint untouched. G-14 NOT AUTHORIZED honored; no real-data processing, no pilot, no workload 46, no chunk 760 access.	2026-09-07 14:15:25 +07:00
