refactor(deploy): venv + steam now under /var/lib/left4me 
Sync deployment references for the runtime state relocation
shipped via ckn-bw (commit 6fae2fd). /opt/left4me/ is now a
root-owned deploy-artifact root (just src/); .venv and steamcmd
live at /var/lib/left4me/{.venv,steam}.

Touches:
- deploy/files/.../left4me-web.service: PATH + ExecStart
- deploy/files/.../left4me-workshop-refresh.service: WorkingDirectory
  (was /opt/left4me, now /opt/left4me/src to match the web unit),
  PATH, ExecStart
- scripts/sbin/left4me wrapper: flask path
- deploy/tests/test_example_units.py: PATH + ExecStart assertions
  for the web unit; also fix a pre-existing broken assertion that
  read "Environment=PATH=..." (the unit has Environment=HOME=...
  PATH=... on one line, so "Environment=PATH=" was never present)
  - now reads just "PATH=..."
- deploy/README.md: paths
- l4d2host/tests/test_cli.py: LEFT4ME_STEAMCMD fixture path

Design + as-shipped record:
docs/superpowers/specs/2026-05-15-runtime-state-relocation-design.md.
The original (narrower) prereq spec at
docs/superpowers/specs/2026-05-15-handoff-noneditable-install.md
is marked superseded with a pointer to what shipped + why the
scope grew (setuptools writes egg-info to source during PEP 517
build prep).

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 uses direnv to auto-activate a Python 3.13 venv on cd (matching the Debian Trixie production target). With direnv installed and hooked into your shell:

  1. direnv allow once per fresh checkout (and after any .envrc change).
  2. cd out and back in — .direnv/python-3.13/ is created and put on PATH.
  3. pip install -e ./l4d2host -e ./l4d2web to install both packages editable.
  4. pip install pytest to run the test suites (pytest tests/ inside either subproject).

Tech Stack (planned)

  • Python 3.12+
  • 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.
