Practitioner advanced topics

Reserve these references for teams that need optional telemetry, performance profiling, or PlotSpec visual narratives. Each topic extends the core explanation workflow without introducing mandatory dependencies.

• Use external plugins - Opt in to curated external plugins (e.g., FAST) and wire them safely.

• Modality plugin selection - Select explanation plugins by modality and understand alias and extension-shim behavior.

• Normalization and Difficulty Estimation - Difficulty estimation and normalized intervals for heteroscedastic regression data.

• Configure telemetry - Opt-in telemetry hooks with privacy defaults and governance cross-links.

• Tune runtime performance (opt-in) - Parallelism, caching, and profiling guidance for high-throughput deployments.

• Reject Policy Guide - Configure RejectPolicy defaults, per-call overrides, and envelopes for reject-aware predictions and explanations.

• Parallel execution playbook (opt-in) - Heuristics for switching between sequential, feature-, and instance-parallel explain strategies.

• Explanation retrieval - Retrieve explanations by rule patterns and metadata filters for audits and analysis.

• Plot explanations with PlotSpec - Optional PlotSpec and triangular plot tooling to visualise factual vs. alternative trade-offs.

• Telemetry (relocated) - Conceptual framing for the telemetry model and its boundaries.
