gedih3.doctor.diagnoses.metadata
================================

.. py:module:: gedih3.doctor.diagnoses.metadata

.. autoapi-nested-parse::

   metadata diagnosis — partition meta JSON + dataset manifest health.

   Detects:
     - Partitions whose merged meta JSON file is missing.
     - A stale or absent ``_manifest.txt`` R2 sentinel at the database root.

   Remedies (safe):
     - Regenerate missing partition meta via ``h3_merge_metadata``.
     - Regenerate manifest via ``generate_manifest``.

   Performance pillar (v0.8.x lessons backport):
     * Both the missing-meta check and the newest-parquet-mtime walk are
       pushed to workers via :func:`gedih3.doctor.parallel.parallel_map`.
       The driver receives a single bool / float per partition and
       aggregates — no driver-side recursive glob over h3_*//*/*.parquet
       on continental DBs.
