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.

|

|
| | | This package re-implements parsing, aggregation and canonical serialization
|
| | | from the specification tables with its own code paths (regex-based line
|
| | | splitter, table-based civil-days math, distinct decimal parser, distinct
|
| | | aggregator). It never imports producer parsing/aggregation/serialization
|
| | | functions. The only shared module is engine/versions (allowed by spec 18.1).
