# Offline tools and test scope

Python 3.10 or newer, standard library only. These tools make no network requests, do not execute uploaded historical scripts and do not change a website or account. Run from the release root:

```
python3 -m unittest discover -s Tools/tests -v
python3 Tools/library_audit.py . --output Reports/library-audit.json
python3 Tools/seo_html_check.py saved-complete-page.html --expect index
python3 Tools/seo_html_check.py saved-complete-page.html --canonical https://example.com/service/
python3 Tools/robots_policy.py Templates/engine-policy.example.json --allow-example --output Templates/robots.EXAMPLE.txt
python3 Tools/jsonld_embed.py Schema.org/article-person.example.json --output article-example.html
```

`seo_html_check.py` evaluates a saved complete document, including title presence, duplicate canonicals, an explicit canonical contract, general/Googlebot meta noindex and JSON-LD syntax. It does not fetch headers, execute JavaScript, check real bot identity, determine CSS visibility or certify structured data eligibility. Header only noindex needs a separate live response test. Length outliers and missing canonical markup are not treated as universal Google errors.

`robots_policy.py` rejects unapproved policies unless example mode is explicit. Marking a JSON field approved does not obtain real owner authorization. The generator repeats private path crawl exclusions in specific allowing groups, validates tokens and requires a same host sitemap in this implementation. It is not a complete robots parser or comprehensive opt out from every unlisted consumer. Authentication must protect private resources.

`jsonld_embed.py` serializes JSON safely for a script element, including script breakout protection. It does not check that the facts are true, that a feature supports the graph or that fictional example values have been replaced.

`library_audit.py` checks scoped local Markdown file targets, release JSON syntax, registered source IDs and the 146 preserved original hashes. It does not validate fragments, arbitrary HTML links, external URL availability, source truth or code embedded in legacy documents.

The test suite uses synthetic fixtures. Passing results are evidence for those implemented checks, not end to end production validation. The original Jaccard script is preserved under `99-Originals` and was not run.

## 26 discipline extension
