mcp_analysis 0.1.4

Analysis engine for the MCP ecosystem providing pipeline-based data analysis with pluggable functions, transforms, and multi-source data integration.

0.1.4 - 2026-07-14 - Standard in-memory builder

Added

• AnalysisPortAdapter.inMemory() — one-line production engine builder (full catalog + synthetic source), closing the standard-builder gap the other capability packages already meet.
• standardBuiltinFunctions() — single source of the built-in catalog.
• dataSourceRegistry getter for post-construction adapter registration.

Fixed

• Summary artifacts now carry the full function-results map as JSON when no 'text' key is present — rich results (fft, lockin, ...) were unreachable through the port artifact surface.

0.1.3 - 2026-07-14 - Filter completion, lock-in, model simulation

Added

• digital_filter: notch, Butterworth order cascade (2..8), median — filter family completion.
• lockin — software lock-in amplifier (synchronous demodulation) for weak tone amplitude/phase extraction (36 built-in functions).
• Synthetic source model kinds state_space / transfer_function / rlc (RK4, ZOH input) and Monte Carlo ensemble percentile bands — in-core linear system simulation and simulation-based prediction.

0.1.2 - 2026-07-14 - Standard function catalog + streaming semantics + performance

Added

• 28 new built-in functions (7 → 35): DSP (fft w/ phase, psd_welch + band powers, spectrogram, cepstrum, harmonics/THD, cross_psd/coherence/FRF, digital_filter, peak_detect, zero_crossing, resample, envelope), timeseries (acf auto-period, cross_correlation, changepoint_cusum, holt_winters, kalman_filter, smoothing w/ Savitzky-Golay derivatives, differencing), statistics (histogram, covariance_matrix, regression, hypothesis_test, pca, lomb_scargle, interpolate), and a built-in domain layer (vibration_indicators w/ ISO 10816 zones, hrv_metrics, eeg_band_powers).
• SyntheticSourceAdapter (AnalysisSourceType.synthetic) — seeded signal/Monte-Carlo generator registered as a data source.
• Streaming semantics: WindowKind.tumbling, maxPoints bounded buffer, watermark late-drop, ReorderBuffer (allowedLateness), drop counters in emitted artifacts.
• descriptive_stats skewness/kurtosis; anomaly_detect mad method.
• Bench harness (bench/) with recorded baselines and targets.

Changed

• WindowAggregator is incremental (Kahan running sums + monotonic deques): add amortized O(1), aggregate O(1) — ~9000x faster at 100K occupancy.
• Floors mcp_bundle ^0.4.8 (AnalysisSourceType.synthetic).

0.1.1 - 2026-05-23 - mcp_bundle 0.4.0 cascade

Changed (cascade)

• mcp_bundle caret bumped from ^0.3.0 to ^0.4.0. mcp_analysis does not touch UiSection.pages directly, so this release is a caret-only cascade. Consumers should bump to ^0.1.1.

0.1.0 - 2026-04-28 - Initial Release

Added

• Spec subsystem — validator, parameter resolver, spec manager.
• Artifact subsystem — builder, store, provenance tracker.
• Execution subsystem — execution engine, batch / ad-hoc / stream executors, job manager, retry policy, step logger.
• DataSource subsystem with pluggable adapters for multi-source integration.
• Pluggable analysis functions and transforms.
• Alert evaluation.
• MCP integration via tools.
• Standard port adapter implementing mcp_bundle analysis Contract Layer.
