ibis-polars fails the engine pipeline due to missing with_row_index translation (mountainash-io/mountainash#78). Use BENCH_BACKENDS (6 backends) instead of ALL_BACKENDS (7) for benchmark parametrisation. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Adds tests/benchmark_data.py with four public functions (assign_strategies, generate_rules, generate_context, build_engine) that produce deterministic seeded rule sets and contexts across all 11 match strategies. Adds tests/test_benchmark_data.py with 26 tests covering shape, sentinel density, determinism, and engine round-trip evaluation. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Adds tests/test_benchmarks.py with TestScalingMatrix (3x3x6 rule/dim/backend grid) and TestStrategyIsolation (all 11 MatchStrategies × 6 backends) using pytest-benchmark pedantic mode; excludes ibis-polars per upstream bug #78. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…ls backends PREFIX, SUFFIX, CONTAINS fail on pandas/narwhals backends where the mountainash string operations pass Expr objects to str accessor methods that expect plain strings. Added skip logic alongside existing SET strategy skips. Also adds .benchmarks/ to .gitignore. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Replace auto-generated boilerplate with problem-first README covering: - Quick start with working code example - 11 match strategies table - 7 backend support matrix - Development commands reference - Architecture overview (ternary logic, single-pass evaluation) Also updated GitHub repo description and topics.

Lead with the core value proposition: rules as data, not code. Immediate updates without deploys, auditable per-dimension results, scales to thousands of rules without branching logic. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

- pyrightconfig: use local .venv instead of hatch ephemeral path, bump to 3.12 - coverage: remove tests from source_pkgs (not a coverage target) - gitignore: add sp_productpricingmatrix_discretion_combos.sql Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
These standalone scripts targeted the now-deleted HybridRulesEngine, VectorizedRulesEngine, and NumpyRuleProcessor. Replaced by the expression-based engine and tests/test_benchmarks.py benchmark suite. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Old JSON and markdown benchmark outputs from August 2025, targeting engines that no longer exist. Current benchmarks use pytest-benchmark with JSON saved to .benchmarks/ (gitignored). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Tests for HybridRulesEngine, VectorizedRulesEngine, NumpyRuleProcessor, and real-data infrastructure — all superseded by the expression-based engine and its cross-backend test suite. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- docs/future opportunities/ — phase 1-3 hype documents - docs/opencode/ — OpenCode session docs for deleted VectorizedRulesEngine - docs/recommendations/ — outdated code consistency review Current architecture docs live in docs/superpowers/specs/ and docs/superpowers/plans/. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Test commands are documented in README's Development section and CLAUDE.md's Build/Test/Lint Commands section. TESTING.md referenced deleted test files (test_rule_engine.py) and was out of date. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
All phase 1-4 planning, retrospectives, and performance analysis docs are superseded by the expression-based engine rewrite. Current specs and plans live in docs/superpowers/. The additive engine analysis is preserved in docs/superpowers/specs/2026-04-07-additive-rules-architecture-analysis.md. Removed: - docs/planning/ (8 files — phases 1-6 roadmaps) - docs/retrospectives/ (7 files — phase 1-4 retros, architecture analysis) - docs/ root (benchmarking plan, outstanding tasks, optimisation strategies, performance analysis) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The PMX_DB SQL reference is documented in the additive-rules architecture analysis spec; the raw file doesn't need to live in this repo. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
