Adds Sphinx doctest Examples sections to DevelopmentCorrelation and ValuationCorrelation. Each example opens with the Mack chain-ladder assumption being tested, prints the full decision signal (statistic, confidence band, and boolean) rather than a single boolean, and ties the result back to the chain-ladder workflow. Refs #704
Adds Sphinx doctest Examples section to the BootstrapODPSample class showing basic fit (resampled_triangles_.shape and scale_), downstream stochastic IBNR via Chainladder, and the effect of drop_high on scale_. Uses random_state=42 and n_sims=100 for deterministic, fast output. Refs #704
Rewords the paragraph introducing the drop_high=True example to describe it as a leave-one-out sensitivity check on the column maxima rather than outlier removal, since drop_high mechanically removes the column max without any outlier test. Addresses review feedback on #836.
Per @henrydingliu review on #844: opening paragraph now scoped to the calendar-effect concept; the per-diagonal vs whole-triangle distinction is introduced as a transition between the two testcode blocks. Refs #704
- Drop the jb build internals + duplicate warnings note (kennethshsu) - Rename 'tutorial notebooks' to 'onboarding and Quickstart notebooks' (kennethshsu) - Drop the 'What to edit for which part of the site' table and 'Known issues' section as redundant with the Source files table and #841 (kennethshsu)

Datetime and global
Optionsbehavior affect valuation dates and test fixtures across the core package; removing deprecated option helpers may break downstream callers that still use them.Overview
Package configuration refactors
chainladder’s public init: Pandas 2/3 datetime compatibility moves fromoptions.DT64_*to module-level__dt64_dtype__/__dt64_unit__, with call sites updated inbase,pandas, andutility_functions.Optionsbecomes an instance class with validatedget_option/set_option, per-option or fullreset_option, and stored defaults; deprecated top-levelarray_backend/auto_sparsehelpers are removed in favor ofchainladder.options.Tests gain shared
_sample_fixtureinconftest.py(backend setup/teardown), expanded options coverage, and datetime tests keyed off__dt64_unit__.Documentation adds contributor
docs/README.md, a Friedland book section (RST doctests for chapters 6–7, WIP chapter 8 notebook, TOC entry), and large numpydoc expansions with runnable examples onDevelopment,BootstrapODPSample, and Mack correlation classes.
