fix(modals): nested-dialog rendering, CM6 destroy on close, mount idempotency 
Three coupled lifecycle bugs surfaced during Task 5-8 reviews:

1. overlay_file_editor.html emitted a <dialog open> that nested inside
   the outer <dialog id="modal-container">, collapsing the modal to
   2px tall. Replaced with <div role="document" aria-labelledby="…">
   so a11y semantics survive and the layout actually renders.
2. modal-router.js's close-event handler now tears down CM6 controllers
   via controller.destroy() and clears #modal-content innerHTML, fixing
   a real leak (each open/close cycle was orphaning an EditorView and
   a matchMedia "change" listener on window).
3. mountOne in editor.js now short-circuits if the textarea already has
   a controller, defending against future double-mount paths.

CSS: added div.modal and div.modal.modal-wide selectors alongside the
existing dialog.modal ones so the editor <div> gets correct styling.

README.md

l4d2-web-app

Flask web app for managing L4D2 servers through user-private blueprints.

Key v1 behaviors

  • Local username/password login; no public signup
  • Admin-managed overlay catalog
  • Private blueprints per user
  • Server creation from blueprints (live-linked; no per-server blueprint overrides)
  • Async job model with persisted command logs in job_logs
  • Desired vs actual state model
  • Live logs for jobs and servers via SSE endpoints
  • Host operations go through l4d2ctl via a local host command runner, not direct l4d2host imports

Frontend constraints

  • Server-rendered templates (Jinja)
  • Vendored HTMX (static/vendor/htmx.min.js)
  • Custom CSS only
  • Tokenized, consistent link and accent colors

Development

From the workspace root (../):

uv sync          # creates .venv, installs l4d2host + l4d2web editable, plus dev deps
uv run pytest l4d2web/tests -q

Configuration

The web app reads these settings from the environment:

  • DATABASE_URL: SQLAlchemy database URL, for example sqlite:////var/lib/left4me/left4me.db.
  • SECRET_KEY: Flask secret key used for sessions and CSRF-sensitive state.
  • JOB_WORKER_THREADS: number of background job worker threads.

In the systemd deployment, environment is loaded from /etc/left4me/host.env and /etc/left4me/web.env.

Admin Bootstrap

Create the first admin account with the Flask CLI. Provide the password through LEFT4ME_ADMIN_PASSWORD:

LEFT4ME_ADMIN_PASSWORD='change-me' flask create-user <username> --admin
