fix(editor): correct caret behavior in autocomplete accept + disable auto-close 
Four smoke-discovered fixes in acceptCompletion / CodeJar options:

- Backward selection walk via Selection.modify replaces the buggy
  range.setStart(endContainer, endOffset - fragment.length). The old
  code assumed the fragment lived in endContainer; at end-of-line the
  caret often sits in a post-Prism-<span> text node, so the subtraction
  went negative → IndexSizeError → caught silently → popup dismissed
  with no insert.
- Save/restore caret around updateCode because codejar.js:469-474 does
  editor.textContent = code; highlight(editor) with no caret preservation,
  which dropped the caret to the start of the editor.
- Set the selection inside the inserted text node before save() so
  CodeJar's save() doesn't trip its anchorNode === editor special case
  at codejar.js:122-127, which collapses to end-of-all-text.
- addClosing: false on both CodeJar constructors so closing quotes
  don't duplicate — CodeJar's addClosing: true default inserts a paired
  closing character without skipping past an existing one, producing
  e.g. "rcon_password"" when you finish a string literal.

README.md

left4me

left4me is a local L4D2 server management platform with two planned components:

  1. l4d2host + l4d2ctl (host library + CLI)
  2. l4d2-web-app (Flask web app for users, blueprints, servers, jobs, and logs)

Status

Implementation plans remain the source of truth for architecture and task sequencing:

  • docs/superpowers/plans/2026-04-22-l4d2-host-lib-v1.md
  • docs/superpowers/plans/2026-04-23-l4d2-web-app-v1.md

Locked v1 Decisions

  • Naming is strictly l4d2 (not l4d).
  • Host library and web app are separate components.
  • Host CLI write commands are fixed to:
    • install
    • initialize <name> -f <spec.yaml>
    • start <name>
    • stop <name>
    • delete <name>
  • Host CLI read commands are available for the web/host boundary:
    • status <name> --json
    • logs <name> --lines <n> --follow/--no-follow
  • The web app calls host operations through l4d2ctl, not direct l4d2host imports.
  • Deployment uses /var/lib/left4me for runtime state, /opt/left4me for repository contents and the virtualenv, /etc/left4me for environment files, and global units under /usr/local/lib/systemd/system.
  • Overlay handling is directory-based; the web app populates each overlay (workshop downloads, managed-global refresh).
  • No lock manager, no rollback, no preflight checks in host library.
  • CLI propagates subprocess failures via stderr and return code.
  • delete on missing instance is no-op success.
  • Blueprint model (web app):
    • user-private in v1
    • servers are live-linked to blueprint
    • no per-server overrides
    • delete blueprint blocked when linked servers exist
    • blueprint changes apply on next action
    • server can reassign blueprint anytime

Planned Repository Layout

  • l4d2host/
  • l4d2web/
  • deploy/
  • docs/superpowers/plans/

Deployment

See deploy/README.md for the Linux test deployment contract, including the runtime user, target filesystem layout, systemd units, privileged helpers, sudoers rules, admin bootstrap, and overlay reference rules.

Local development

This repo is a uv workspace (l4d2host + l4d2web as members) with a committed uv.lock and a .python-version pinning Python 3.13 (matching the Debian Trixie production target).

One-time prereq: install uv (macOS: brew install uv; Linux: curl -LsSf https://astral.sh/uv/install.sh | sh — uv is not yet in Debian stable's apt).

  1. direnv allow once per fresh checkout (and after any .envrc change). .envrc uses use uv, which runs uv sync and activates .venv/ on cd.
  2. Without direnv: uv sync at the repo root creates .venv/, installs both workspace members editable, and pulls in dev deps (pytest) from the lockfile.
  3. Tests: uv run pytest (or just pytest once the venv is on PATH).

Tech Stack (planned)

  • Python 3.13+ (workspace uses uv + hatchling)
  • Typer, PyYAML, pytest
  • Flask, SQLAlchemy, Alembic
  • HTMX (vendored locally), custom CSS, SSE
  • systemd units, kernel overlayfs (mounted via the left4me-overlay privileged helper), steamcmd

Recommended Implementation Order

  1. Implement l4d2host plan first.
  2. Implement l4d2web plan second.
  3. Keep tests green task-by-task (TDD flow from plans).
  4. Keep commits small and aligned with plan tasks.

Contributing Notes

  • Follow plan task order unless explicitly re-planned.
  • Keep contracts above unchanged unless the user asks to change them.
  • Update plan docs when scope or behavior changes.
