seo-rendering

# seo-rendering (M4) Content that only exists after hydration is invisible to any consumer that does not run JavaScript. Google renders JS (documented); most third-party AI crawlers are **reported** not to (directional — see Honesty), so a CSR-only shell is primarily an AI-visibility and crawl-efficiency problem. JS dependency also delays first paint; see `references/cwv-thresholds.md` for how this feeds LCP/INP. ## Inputs Work from the PageSnapshot named in your dispatch envelope: read `parsed` from `<run_dir>/pages/<slug>.json` and `parsed_rendered`, plus the `render{needed,signals,used,confidence,hint,delta}` block — the script already computed the raw-vs-rendered delta; `raw_html_path`/`rendered_html_path` name the files on disk; Grep `pages/<slug>.html` for verbatim evidence; site artifacts live in `<run_dir>/site/{robots.json,sitemaps.json,discovery.json}`. Deterministic findings already emitted by `audit.mjs` are listed in `<run_dir>/findings.deterministic.json` — do not re-emit those ids; add model-judged findings only. If invoked directly with a URL/path and no snapshot exists, first run `node "${CLAUDE_PLUGIN_ROOT}/scripts/snapshot.mjs" <target> --out "${CLAUDE_PLUGIN_DATA}/runs"` and use the printed snapshot path. ## Audits Working from the PageSnapshot (`parsed_rendered` when `render.used` is not `none`, else `parsed`) and the script-computed `render.delta`: 1. **Content delta**: diff `raw_html_path` vs `rendered_html_path` — measure the share of primary text, ...
