refactor(files): collapse files_overlay binary mode into per-capability gates 
Read-only file explorers (server detail page, read-only overlay) used
to omit the hover-action panel entirely and make the filename itself
the download link. Editable overlays did the opposite: hover-action
panel with download + delete, filename-click opens the editor.

Unify both surfaces around the editable pattern: always emit the
hover-action span when any action applies. Gate the download button
on download_supported only (now visible on all surfaces). Keep
delete + folder actions (+file, +folder, zip) gated on files_overlay,
since read-only surfaces never offer those. In read-only mode, the
filename becomes a plain <span> — the hover ⬇ is the single download
affordance, matching editable mode's filename-click ≠ hover-download
split.

Prefactor for the files-overlay.js rewrite (docs/superpowers/plans/
2026-05-17-files-overlay-rewrite.md). No JS changes; files-overlay.js
doesn't run on read-only surfaces (manager-element guard at line 23-24).

Verified: pytest stayed at 573/1/3 (URL substrings still appear in the
rendered HTML even though they moved out of the filename anchor into
the hover-action span). Direct Jinja render confirmed all four
branches: read-only downloadable file (new hover ⬇, plain <span>
filename), broken read-only symlink (no hover panel — correct, can't
download dangling links), read-only download_supported=False (no
hover panel, plain <span>), editable mode (byte-identical to before).

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
