Feature inventory

Working checklist (not shipped polish) of every user-triggerable control on the site, built mechanically from the ROUTES table in web/assets/js/core/app.js and a grep of anr-btn/addEventListener/ <button/<select/quoted label strings across every renderer. This is the contract Phase D (docs/features/*.md) must satisfy - tick a row once its feature doc covers it. Grouped by the feature doc that owns it.

On this page

Note on vssolution.js: this renderer is not assigned to any docs/features/*.md file in research/DOCS_PLAN.md's deliverables table (a gap in the plan). It has no interactive controls (pure VS-solution metadata display), so it is listed under data-archive.md here for consistency with its domain grouping in renderers.md, and covered there in Phase D.

Coverage notes#

  • Every ROUTES renderer in app.js is represented above via its owning module (photo/audio/video/docx/xlsx/... map 1:1 to the renderer files listed).
  • Every anr-btn-creating renderer found by Grep pattern="anr-btn" path="web/assets/js/renderers" (40 files, matching the plan's stated count) is represented with its button labels.
  • Renderers with no anr-btn hits were additionally checked for addEventListener/<select/<input type=range> controls; most are pure metadata-display modules with no interactivity, noted as such above.
  • Lazy sub-feature relationships (e.g. photo.js -> sonify.js, model3d.js -> stl.js/gcode.js/archive.js, illustrator.js -> pdf.js, csv.js/xlsx.js/xlsb.js/odf.js -> tablekit.js, odf.js/legacy-office.js/textdoc.js -> paged.js, tiff.js/ico.js/mpo.js -> embedded-images.js) are noted inline so the owning feature doc credits the sub-feature to its parent's workflow.
