Three-phase plan to consolidate files-overlay.js's mixed event-binding
patterns and complete the URL-addressable modals migration:
Phase A (4 commits): split the 35 KB IIFE into 4 focused modules
under static/js/files-overlay/ — core, editor, dialogs, uploads —
with consistent document-level delegation. Behavior unchanged.
Phase B (6 commits): migrate the two remaining inline-dialog flows
(create-new-file, binary-replace) to URL-addressable modals via a
new /files/new route and a binary-mode branch in the edit route +
template. Delete the legacy <dialog id="files-editor-modal"> from
overlay_detail.html. editor.js becomes single-purpose (~200 lines).
Phase C (2 commits): extract shared path/editability helper for
routes/files_routes.py; delete the now-unused /files/content JSON
endpoint; consolidate save/replace rename duplication.
Each commit is independently verifiable + revertable. Natural pause
points at the end of each phase. Plan is the handoff artifact for
cross-session execution.
