BenchBox 0.1.4

Added

• power_bar chart type - Added a horizontal bar chart for TPC Power@Size comparisons.
  Higher values are treated as better (opposite of performance_bar), powered by
  summary.tpc_metrics.power_at_size and exposed in NormalizedResult.
• power_bar template coverage - Added to flagship, head_to_head, trends,
  regression_triage, and executive_summary. The chart renders only when TPC metric data is
  present and is skipped for non-TPC runs.
• Driver-version-aware chart labeling - Multi-platform chart series labels and run summaries
  now include driver version context so version comparisons stay explicit in rendered output.
• Runtime ABI validation for isolated drivers - Added ABI compatibility checks to isolated
  runtime discovery so driver auto-install paths fail fast with actionable validation errors
  instead of late runtime crashes.
• Presorted data-generation modes for table formats - Added parquet-sorted output mode,
  plus delta-sorted and iceberg-sorted organization paths with clustering primitives
  (z-order, Hilbert, partition-aware sorting) and cluster-by tuning integration.

Fixed

• Query plan capture correctness and persistence - Fixed multiple plan-capture defects:
  forwarding capture_plans through RunConfig, DuckDB JSON plan parsing edge cases,
  preservation of query_plan through normalization, and show-plan / compare-plans
  loading through the standard result-file path.
• SSB dot-notation query IDs - --queries now accepts IDs like Q2.1, and plan-oriented
  CLI flows preserve dotted IDs instead of normalizing them away.
• Result timing pipeline accuracy - Fixed datagen/load timing propagation end-to-end,
  including per-table load timings in table_statistics, corrected load-phase duration keying,
  datagen phase duration and manifest stats in metadata, and explicit total duration override
  propagation in result builders. Data-only runs now correctly execute generation, and
  force_regenerate is forwarded through CLI and runner paths.
• ASCII visualization readability under skewed data - Fixed outlier handling across chart
  types (bar, histogram, stacked, scatter, line, CDF, percentile ladder, heatmap), addressed
  zero-heavy fallback truncation edge cases, improved natural query sorting and color cycling,
  and raised effective render width cap from 120 to 400 characters.
• --quiet output contract for automation - Quiet mode now emits only the bare result
  filepath to stdout, removing decorative output that broke script parsing.
• Runtime environment stability - Fixed interpreter targeting for driver auto-install,
  corrected auto_install_used state propagation, and resolved SIGSEGV-class failures when
  driver_auto_install=true reused an already-matching version.
• Additional correctness fixes - Restored ai_primitives registry resolution fallback,
  corrected SQLite force_recreate option handling, fixed SSB customer row-count expectation in
  SSBRowCountStrategy, and resolved visualize command crashes / multi-series rendering issues.

Changed

• Plan-capture default now uses actual execution timing - --capture-plans now defaults to
  EXPLAIN (ANALYZE, FORMAT JSON) behavior via analyze_plans=True, recording measured timing
  in captured plans. Users can opt out with analyze_plans: false for estimate-only capture.
• Benchmark runtime/result internals harmonized - Refactored enhanced result construction to
  use a shared factory path and aligned canonical runtime behavior for benchmarks like NYC Taxi
  and TSBS DevOps.
• make test-all resource policy and parallelism - Resource-heavy tests are now serialized
  to prevent machine stalls, while slow/performance suites are moved to a dedicated stress lane.
  The test suite also replaces fixed sleeps with bounded polling, reduces fixture/harness
  duplication, and shifts selected CLI/e2e coverage to in-process runners for faster execution.
• CI quality gates tightened - Added required table-format integration coverage and promoted
  doc checks (linkcheck, example validation, docstring coverage) plus security audit policy
  controls to blocking CI behavior.
