"""W607-BQ -- ``cmd_clones`` substrate-boundary plumbing.

Forty-eighth-in-batch W607 consumer-layer arc. cmd_clones completes the
W805 paired-scoring detector family:

* W607-BK  cmd_dark_matter   (co-change correlation)
* W607-BM  cmd_duplicates    (metric-similarity)
* W607-BN  cmd_smells        (anti-pattern)  -- pending
* W607-BQ  cmd_clones        (AST-subtree-hash)  <-- this wave

All four detect DRY/architecture debt from different signal axes on the
same corpus. The marker-prefix discipline test pins the W607-BQ markers
to the ``clones_*`` family so a future drift into ``dark_matter_*`` /
``duplicates_*`` / ``smells_*`` is caught.

Substrate inventory:

* query_candidates             -- the AST-subtree-hash ``detect_clones``
                                  read call.
* apply_test_prod_separation   -- W165 test/prod/mixed filtering on the
                                  ``--exclude-tests`` /
                                  ``--exclude-fixtures`` paths.
* classify_role_buckets        -- W856 cross-layer cluster classification
                                  for the verdict-line ``role_buckets``
                                  count.
* emit_findings                -- ``--persist`` registry mirror
                                  (``store_clones`` +
                                  ``_enrich_clones_findings_with_role_bucket``
                                  + ``conn.commit()``). Pattern-2
                                  elimination target.
* serialize_to_sarif           -- ``clones_to_sarif`` projection for CI
                                  gates.

Marker family ``clones_<phase>_failed:<exc_class>:<detail>`` (underscore
form -- matches the W805 paired sibling marker discipline).

W978 first-hypothesis check
---------------------------

Each W607-BQ-wrapped substrate has a documented empty-floor default that
matches its happy-path return shape so a raise degrades cleanly. The
read-side ``detect_clones`` defaults to ``([], [])`` (the same tuple
shape callers receive on a no-clone corpus).

PATTERN-2 ELIMINATIONS
----------------------

The implicit "no error handling around the persist write" path is now
explicitly wrapped via ``_run_check_bq("emit_findings", ...)``. The
pre-W607-BQ code would have unwound the entire CLI on a
sqlite3.OperationalError surfacing from ``store_clones`` (locked DB,
full disk, missing column on a stale schema). The downstream-helper
``_enrich_clones_findings_with_role_bucket`` already had an internal
``except sqlite3.OperationalError: return 0`` clause for the missing
findings-table case; that helper-level fallback is correct (contained
schema-probe) and stays in place. The wave's elimination target is the
unguarded persist-write at the call site, which is now wrapped.

W805 PAIRED-SCORING FAMILY 4-WAY CLOSURE
----------------------------------------

The (10) test below closes the family loop -- after W607-BQ lands,
the four sibling detector marker families
(``dark_matter_*`` / ``duplicates_*`` / ``smells_*`` / ``clones_*``)
are pinned non-colliding.

W855/W856 RENAME-INVARIANT + CROSS-LAYER REGRESSION GUARD
---------------------------------------------------------

The (11) test confirms that the W855 (rename-invariant) + W856
(cross-layer) clone-detector subkinds do not collide with the W607-BQ
``clones_*_failed:`` marker prefix family.
