Changelog

This is development history, not a release log. The 0.2.0 section below is written from the implementation on branch lunartrace/ara199-py02. The sections after it are derived from git log --oneline -60 on lunartrace/r3-ux and grouped by theme; the commit log does not carry dates in this view, so the order is the order of the branch, newest first. Nothing here has been published.

0.2.0 (unreleased): the one-call Study

• lt.temporal.study(site=, event=, products=, archive=) compiles the PRE/POST temporal Study in one call. It is a facade over the unchanged method lunartrace.temporal_prepost/v1: the record from the retained Vikram pages is byte-identical to the committed study-minute.json (digest sha256:3d75a662ce75f00cd34dd9ba288012ad471c73b1e56ecf0abe36896d0b199dd0) and no field was added to it.
• Study views over the record: frontier (angles 13, angles+resolution 56, angles+time 133, all 342), why, pair, anatomy (seven sections), limits, verify, save, replay and to_notebook. load reads a saved file and verifies it.
• lunartrace.sites registers Vikram with its four event bases. lunartrace.science.ode holds the Lunar ODE fetch and retained-source custody, moved from tools/vikram_study.py.
• The snapshot vikram-2026-10-14 ships inside the package, so archive="vikram-2026-10-14" replays offline. Without archive, the call fetches Lunar ODE now and is marked live.
• The lunartrace console script: study, why, verify, replay, notebook.
• A marimo notebook export of a saved Study.
• New documentation section The one-call Study, whose examples are run by the test suite.
• Version 0.2.0, published to PyPI as lunartrace. A breaking release: the 0.1.x API and command line are removed (see the root CHANGELOG.md). The documentation site is live at lunartrace.org/docs.

Documentation polish

• Added a newcomer route from installation through real Site01 execution and local workbench startup, with source-install commands exercised on the authoring host.
• Mirrored Explore, Analyze, Compare, Publish and Present in the scientific workflow, preserving the distinctions between sampled cells, exact rows, capsules and Studies.
• Documented the property-based boundary failures recorded in 755434a, alongside independent oracle agreement and explicit numerical/admission ceilings.
• Added dependency-free validation of built internal links, fragments, image alt attributes and main-content heading order, including the deployed /docs base.
• Pinned the existing Pagefind indexer and UI to compatible 1.4.0 after browser verification exposed relative metadata fetches from 1.5.2’s blob worker. The deployed /docs search was then exercised with real indexed results.

Notes

• The R2 page remains available at /r2 as a historical surface. Its commits are retained as history.
• The package release log is the root CHANGELOG.md. This page does not stand in for it. See Release status.
• The manual is maintained in docs-site/; tools/gen_api_docs.py generates the Python reference from source docstrings. Its generated API is checked before every docs build.
