v0.8.3 (2026-03-26)

This release is published under the Apache-2.0 License.

Bug Fixes

  • Address PR review feedback (2a40b53)

Gate _log_residual() diagnostic work behind logger.isEnabledFor(DEBUG) to avoid scanning all_flat when debug logging is disabled.

Fix test docstring/name mismatch — test checks for valid output, not identical output.

  • Eliminate silent data loss for nested arrays in render_table (4d79b4f)

render_table() had no fallback for array fields that couldn't be inlined or extracted as sub-tables — data silently vanished. This affected Prometheus time-series values, Istio routing rules, and any nested arrays that didn't fit the narrow inline/sub-table constraints.

Add residual field tracking: after inlining and sub-table extraction, any remaining array fields are rendered via recursive condense() (for arrays of dicts) or json.dumps() (for primitives/mixed). Sub-tables now also recurse through render_table() so their nested arrays get the same treatment.

Adds 4 new benchmark fixtures (Prometheus, Elasticsearch, Istio CRDs, JSONL access logs) with 60 questions and diagnostic logging for residual fields to guide future heuristic work.

  • Improve identity column detection for compound names like InstanceId (d4bfe90)

Identity column matching used exact last-segment comparison, so compound names like InstanceId, NodeName, SubnetId never matched keywords "id" or "name". This caused poor identity column selection in split-mode wide tables — IamInstanceProfile.Id was chosen over InstanceId, and State.Name over Tags.Name.

Changes:

  • Add _col_matches_keyword() with CamelCase/separator boundary detection
    to avoid false positives (valid, liquid, filename rejected)
  • Score candidates by (cardinality, avg_value_length, depth) via shared
    _identity_score() helper
  • In render_split, limit repeated identity columns to best 2-3 per
    keyword with lazy stats computation
  • Update find_identity_column, _find_identity_from_cleaned, order_columns,
    and render_split to use suffix matching consistently

Documentation

  • Update token reduction benchmarks with accurate numbers (0558347)

Add 5 new fixtures to the table (App performance, Prometheus, Elasticsearch, Istio, JSONL access logs). Update EC2 from 86.9% to 56.3% — the old number was inflated by silently dropped sub-table data.

Detailed Changes: v0.8.2...v0.8.3
