BIG5-ZH-FACET-IMPORT-DRYRUN-01: validate combined 31-page Chinese Facet import package

[fermatmind]

What changed

• composed one Facet Hub plus thirty Facet assets into one deterministic V1 importer envelope
• recorded source and combined SHA-256 values and 31-row QA evidence
• validated the generic importer strictly in dry-run mode

Why

A single no-write gate is required before any controlled production importer workflow can be considered.

Validation

• combined validator: 31 unique rows, 1 Hub + 30 Facets, body_md, noindex, zero discoverability
• generic importer: 31 found / 31 valid / 0 errors / 31 planned creates / no writes
• focused contract: 14 tests / 421 assertions
• full core CI passed; Big Five 1180/150138, full-32 59/4847
• JSON/YAML, diff, and allowed-file scope checks

Intentionally deferred

• CMS and production import
• production importer workflow
• runtime readback and SEO leakage closeout

Repository rule impact

No authority or runtime change. This PR is deterministic dry-run evidence only.
