Complete the LANfactory documentation quality closeout

[AlexanderFengler]

Purpose and impact

Complete LANfactory's documentation-quality closeout so readers have a coherent learning path, an exact public API/CLI reference, and current ONNX/HSSM and Hugging Face handoff guidance. The change also makes tutorial execution and source/rendered parity enforceable in CI.

Key points

• Documents all six installed commands and every LANfactory-owned Typer flag/alias, including required/default behavior.
• Clarifies that upload-hf generates metadata when model_card.yaml is absent and that --require-model-card restores strict validation.
• Completes the public config, hf, and network_inspectors reference surfaces with dynamic drift tests.
• Keeps HSSM as the owner of the ONNX consumer contract while documenting each LANfactory exporter at its owning source.
• Focuses the JAX material as a backend how-to and adds canonical marimo sources for the revised tutorials.
• Dynamically discovers committed rendered tutorials and runs rendered notebooks, marimo sources, source/rendered parity, and output-portability checks in CI.
• Preserves the exact five-section docs structure and strengthens cross-links without publishing theme-input files.

Verification

• ./scripts/docs.sh build using Python 3.12, uv 0.12.2, offline dependency resolution, and the exact pinned docs stack — passed; strict site built with site/index.html.
• python -m pytest -p no:rerunfailures tests/test_docs_api_reference.py --no-cov -q — 5 passed, including dynamic script discovery and exact per-command flag coverage.
• python -m pytest -p no:rerunfailures tests/test_notebooks.py --run-notebooks --no-cov -q -k 'committed_notebook_outputs_are_portable or marimo_source_matches_rendered_notebook' — 7 passed, 7 deselected.
• Full notebook execution evidence — 14/14 passed on the same tutorial blobs; final-head blob identity was rechecked, and the current PR CI will execute the full suite again.
• ruff check src/lanfactory — passed.
• ruff format --check . — 68 files already formatted.
• All six installed commands with --help — passed; upload-hf help states that model_card.yaml is optional by default.
• actionlint .github/workflows/docs.yml .github/workflows/reusable-docs.yml .github/workflows/run_tests.yml — passed with actionlint 1.7.12.
• Lychee 0.24.2 against rendered HTML with the Pages project-root mount and --offline — 2,007 total, 392 unique, 1,176 OK, 0 errors, 831 external links excluded.
• Documentation graph check — exact Home, Learn, How-to guides, Explanations, Reference order; 18/18 pages in nav; zero content-orphan pages.
• Rendered hygiene — no JEAM/private filesystem paths; no rendered overrides/; shared workflow and four brand files byte-identical to HSSMSpine.

Dependencies and deferrals

• Based on main after Align the documentation legal notice #126, which deployed the corrected MIT legal notice successfully.
• No dependency or version-pin changes and no unreleased sibling-branch dependency.
• HSSM continues to own and enforce the consumer-side ONNX contract; this PR links to that canonical rendered guidance.
• External URL probing remains on the existing weekly/manual docs cadence; this closeout verified all rendered local links offline.

Summary by CodeRabbit

• Documentation

  • Added comprehensive CLI, configuration, Hugging Face, and network inspector API references.

  • Clarified ONNX export contracts and links to downstream HSSM resources.
  • Added and updated JAX, BayesFlow, and sbi tutorials.

• Bug Fixes

  • Corrected PyTorch CLI help text and clarified model-card requirements and upload behavior.

• Tests

  • Expanded documentation and notebook validation, including portability and source-to-rendered synchronization checks.

📝 Walkthrough

Walkthrough

The pull request expands API references, revises ONNX and Hugging Face documentation, adds a JAX LAN training tutorial, and validates all rendered tutorials and canonical marimo sources.

Changes

Documentation and tutorials

Layer / File(s)	Summary
Public API references and navigation docs/api/*, docs/index.md, docs/what_are_lans.md, mkdocs.yml, src/lanfactory/cli/torch_train.py, tests/test_docs_api_reference.py	Documents CLI commands, configuration dictionaries, Hugging Face APIs, and network inspectors. Updates navigation, API links, and the PyTorch CLI description. Adds consistency checks for documented exports, constants, commands, and options.
ONNX and Hugging Face guidance docs/exporting_*.md, docs/tutorials/exporting_*.ipynb, docs/using_huggingface.md, src/lanfactory/cli/upload_hf.py	Defines exporter and HSSM responsibilities, concrete single-trial ONNX inputs, Hugging Face publication safeguards, metadata behavior, and continuation links. Updates related tutorial text and CLI help.
JAX LAN training tutorial notebooks/basic_tutorial_lan_jax.py	Adds a marimo tutorial that generates DDM data, trains a Flax MLP, reloads its state, runs JIT inference, and plots LAN likelihoods.
Rendered notebook validation .github/workflows/run_tests.yml, tests/test_notebooks.py	Extends notebook discovery and execution to all rendered tutorials. Checks portable outputs and synchronization between marimo sources and committed notebooks.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to c8b5c

The PR improves tutorial execution and public documentation, but one JAX tutorial can reuse stale training state after retraining and the overview omits the supported gonogo network type, which may leave readers with stale results or incomplete guidance. These are bounded follow-ups, so the PR is mergeable with explicit owner awareness.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

Inline comments:
In `@docs/index.md`:
- Around line 43-45: Update the LANfactory overview text to include gonogo
alongside LAN, CPN, and OPN as a supported network type, preserving the existing
description of simulated-data training and ONNX export.

In `@docs/using_huggingface.md`:
- Around line 18-20: Update the code blocks in docs/using_huggingface.md,
including the blocks near the installation and examples, to use the repository’s
configured indented code-block style so markdownlint MD046 passes.

In `@notebooks/basic_tutorial_lan_jax.py`:
- Around line 215-223: Rename the training result to train_state and return it
from the training cell, then reference train_state in the inference cell so
forward_pass_jitted depends on the latest training run. Preserve the file-path
state argument to continue demonstrating state reload.
- Line 149: Reformat the assignment calling
lanfactory.trainers.make_train_valid_dataloaders so it conforms to Ruff’s
88-character line limit, using a multiline layout without changing its behavior.

Apply the same fix in `@tests/test_notebooks.py` around lines 59 - 61: Same
line-length remediation applies to the portability regular expression.

In `@tests/test_docs_api_reference.py`:
- Around line 112-115: Update the option-flag extraction loop in
test_every_installed_cli_has_an_exact_option_reference so slash-separated paired
boolean declarations such as --publish-root-alias/--no-publish-root-alias are
split into and added as individual flags, matching _cli_option_flags while
preserving handling of single flags.
