Host-side identifier (systemd unit name and /var/lib/left4me dirs) is now
str(server.id), centralized in services/server_identity.server_unit_name.
Server.name becomes a free-form display label, required and unique per
user (was [a-z0-9_-]{1,64} and globally unique).
Migration 0006 swaps the old global UNIQUE(name) for UNIQUE(user_id, name).
Web routes already keyed on id; templates only used name for display.

Bundles four reference script overlays (cedapug_maps, l4d2center_maps,
competitive_rework, tickrate) and adds a `flask seed-script-overlays`
CLI that upserts each *.sh as a system-wide overlay. Test deploy
invokes it after the orphan-cleanup migration so fresh test servers
come up with the same overlays the user has been maintaining by hand.

Reset stops the systemd service, unmounts the overlay, and rm -rf's both
runtime/<name> and instances/<name>, but keeps the Server row, blueprint,
and (shared) systemd template. Next Start re-initializes from the current
blueprint, so users can clean up logs/caches/accumulated game state without
losing the server.
Implementation factors a shared _purge_instance helper out of
delete_instance; reset_instance reuses it without the existence guard. New
"reset" lifecycle op flows through the same route + worker + facade plumbing
as the other server ops.

The delete job ran l4d2ctl delete (host-side cleanup) but never removed the
Server row, so deleted servers kept appearing on /servers. Hard-delete the
row in the worker's success path and skip the post-op status refresh, since
the systemd unit is gone.

Saving a script overlay or adding/removing workshop items now redirects to the
enqueued build job's detail page so logs are immediately visible. Added a new
/overlays/<id>/jobs page (linked as "all builds →" from the overlay detail
page) for browsing the full build history. Renamed the script "Save" button to
"Save and build" to make the side effect explicit.

The route /admin/global-overlays/refresh was removed with the script-overlays
rewrite (migration 0005 dropped the global_overlay_* tables; the systemd
refresh units were deleted from deploy/). The admin-page form was left
behind and would 404 on submit. Drop the section and lock it out with an
assertion in the existing admin-pages test.

The web service unit has PrivateTmp=yes: its /tmp is a per-instance
namespace at /tmp/systemd-private-X-left4me-web.service-Y/tmp/ from
PID 1's perspective. When ScriptBuilder writes /tmp/tmpXXX.sh and
passes that path to the sandbox helper, systemd-run asks PID 1 to set
up BindReadOnlyPaths=${SCRIPT}:/script.sh — but PID 1 lives in the host
namespace and can't resolve the web service's PrivateTmp path. The
unit fails to start with status=226/NAMESPACE and "Failed to set up
mount namespacing: /script.sh: No such file or directory".
Move the tmpfile to ${LEFT4ME_ROOT}/sandbox-scripts/. /var/lib is not
affected by PrivateTmp (only /tmp and /var/tmp are), so PID 1 can
resolve the path. The web service has ReadWritePaths=/var/lib/left4me
already, and the directory is created on demand by Python.

HTML <textarea> form submission encodes line breaks as CRLF per spec.
Storing those CRLFs unchanged means every line of the script reaches
bash with a trailing \r, which bash treats as part of the argument —
turning "ls /" into "ls /\r" and failing. Normalize CRLF/CR → LF in the
/overlays/{id}/script handler so storage and the sandbox tmpfile are
LF-only.

NamedTemporaryFile creates the script file at mode 0600 owned by the
left4me web user. The sandbox runs as l4d2-sandbox and bwrap bind-mounts
the file read-only at /script.sh, but the kernel still enforces the
underlying file's permissions — l4d2-sandbox can't read 0600 left4me
files, so /bin/bash /script.sh fails with "Permission denied".
Script content is not a secret (it's stored in the DB and editable by
the user), so 0644 is appropriate.

Adds the script type to the create-overlay modal (with an admin-only
system-wide checkbox) and a script-section to the detail page: textarea
for the bash body, Save / Rebuild / Wipe buttons, last_build_status
badge, latest-build-job link, and a Wipe confirm modal. Removes the
GlobalOverlaySource block.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds POST /overlays/{id}/script, /wipe, /build under the overlay blueprint.
Generalizes /build to handle any owner/admin-editable overlay (deletes the
duplicate workshop-specific manual_build). Wipe runs the literal script
"find /overlay -mindepth 1 -delete" through run_sandboxed_script and
refuses with 409 while a build_overlay job is running. Adds an
admin-only system_wide=1 flag to POST /overlays for system-wide creation.

GLOBAL_OPERATIONS becomes {"install", "refresh_workshop_items"}.
Removes refresh_global_overlays_running from SchedulerState and the
_run_refresh_global_overlays dispatch. Drops dead test cases and pins
GLOBAL_OPERATIONS contents.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Deletes the global_map_sources, global_overlay_refresh, global_map_cache,
and global_overlays service modules and their tests. Removes the
refresh-global-overlays CLI command, the /admin/global-overlays/refresh
route, and the GlobalOverlaySource view in overlay_detail rendering.
Drops py7zr from dependencies — was only used by the deleted subsystem.
The job_worker scheduler still tracks refresh_global_overlays; that
cleanup is Task 4. Deploy/README references are Task 8.

Adds ScriptBuilder that runs user-authored bash inside the
left4me-script-sandbox helper via run_command, with a 20 GB post-build
disk cap. Registry now {"workshop", "script"}.
finish_job writes Overlay.last_build_status on build_overlay completion.
Drops GlobalMapOverlayBuilder and the now-unreachable
_check_global_overlay_caches in l4d2_facade.

stream_command used a blocking proc.stdout.readline() that never woke
when the underlying journalctl was silent, so Flask never delivered
GeneratorExit on client disconnect — the worker thread and the journalctl
child both leaked permanently and pinned the gunicorn thread pool.
Switch to a select-based read loop with a 15s heartbeat tick (yielded as
""), and translate the tick to an SSE keepalive comment in the log route.

The workshop + managed-global overlay surface fully covers the
admin-SFTP flow that 'external' was a placeholder for. Drop the type
from the model defaults, builder registry, routes, template, and
tests, and add migration 0004 that deletes any leftover external
rows along with their blueprint and job references.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds two managed system overlays (l4d2center-maps, cedapug-maps) that
fetch curated map archives from upstream sources and reconcile addons
symlinks for non-Steam maps. A daily systemd timer enqueues a coalesced
refresh_global_overlays worker job; downloads, extraction, and rebuilds
run in the existing job worker and surface in the job log UI.
Schema: GlobalOverlaySource / GlobalOverlayItem / GlobalOverlayItemFile
plus nullable Job.user_id so system jobs render as "system" in the UI.
The new builder reconciles symlinks against the per-source vpk cache
and leaves foreign symlinks untouched. Initialize-time guard refuses
to mount a partial overlay if any expected vpk is missing from cache.
Refresh service uses shutil.move to handle EXDEV when /tmp and the
cache live on different filesystems.

Limit workshop refresh downloads to one worker and commit build-overlay enqueue work before writing the final job log so SQLite locks do not wedge the web process.
Before invoking l4d2ctl initialize, run each blueprint overlay's builder
synchronously and then verify that every workshop item attached to the
blueprint has a cache file on disk. If any are missing, raise a clear
error naming the overlay and the missing steam_ids — server start can't
silently mount a partial overlay where some maps are mysteriously absent
in-game.

Adds workshop_routes blueprint with add-items / remove-item / manual-
build endpoints plus admin /admin/workshop/refresh. Add-items handles
single ID, single URL, multi-line batch, or a collection ID; auto-
enqueues a coalesced build_overlay job per call. Reject non-L4D2 items
with 400, duplicate associations with friendly toast, intruders with
403.
Generalizes overlay_routes: type+name only on create (no path field);
external is admin-only and system-wide, workshop is per-user and
auto-pathed. Update is name-only. Delete recursively removes the
on-disk dir only for managed paths (path == str(id)); legacy externals
are left in place. The pre-existing in-use guard is preserved.
Page routes filter the overlay listing by user permissions and load
workshop items + the latest related job for the detail view.
Templates: unified Create modal with type radio (no path field).
Type-aware overlay detail: workshop overlays show a multi-line input
+ items/collection radio + item table partial with thumbnails, manual
Rebuild button, and a small status indicator pulled from the latest
related job. Admin page gets a "Refresh all workshop items" button.

Extends SchedulerState with running_overlays / refresh_running /
blocked_servers_by_overlay, and updates can_start with the truth table:
install and refresh_workshop_items are global mutexes; build_overlay
serializes per-overlay; server jobs block on builds for any overlay
their blueprint references.
Adds enqueue_build_overlay coalescing helper that returns an existing
queued job for the same overlay rather than inserting a duplicate.
Adds run_job dispatch for build_overlay (BUILDERS[overlay.type].build)
and refresh_workshop_items (re-fetches metadata, re-downloads on
time_updated/filename change, enqueues coalesced rebuilds for affected
overlays).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds l4d2web/services/overlay_builders.py with a BUILDERS dict mapping
Overlay.type to a builder class. ExternalBuilder is a no-op that just
ensures the overlay directory exists. WorkshopBuilder diff-applies
absolute symlinks under left4dead2/addons/ against the overlay's current
WorkshopItem associations: creates new ones, removes obsolete, leaves
unrelated files alone, and skips uncached items with a warning rather
than producing dangling symlinks.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds workshop_paths.cache_path(steam_id) returning
$LEFT4ME_ROOT/workshop_cache/{steam_id}.vpk with digit-only validation.
Adds overlay_creation.generate_overlay_path(id) and
create_overlay_directory(overlay) with exist_ok=False so a stray dir from a
prior failed delete surfaces loudly instead of shadowing fresh content.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds l4d2web/services/steam_workshop.py: parse_workshop_input (single ID,
URL, or multi-line batch), resolve_collection (HTTPS POST to
GetCollectionDetails), fetch_metadata_batch (HTTPS POST to
GetPublishedFileDetails with consumer_app_id == 550 enforcement that
raises WorkshopValidationError in add-mode and silently skips in
refresh-mode), download_to_cache (atomic + idempotent on mtime+size),
and refresh_all (ThreadPoolExecutor with per-item error collection).
Adds requests as an explicit dependency.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds Overlay.type and Overlay.user_id with two partial unique indexes
(externals globally unique by name; user overlays unique per user).
Adds WorkshopItem registry keyed on steam_id and a pure many-to-many
overlay_workshop_items association. Adds Job.overlay_id for build_overlay
job tracking. Switches overlays.id to AUTOINCREMENT so deleted IDs are
never reused.

- Per-row "Create server" link on /blueprints navigates to
/servers?blueprint_id=<id>; that page validates the param against
the user's owned blueprints, pre-selects the option, and auto-opens
the create modal.
- /servers empty-blueprint state now shows an actionable
"Create a blueprint first ->" link (styled like the primary button)
pointing at /blueprints, replacing the silent disabled "+ Create"
button + muted hint.
- Drop the "Reassign blueprint" form on the server detail page
along with the unused POST /servers/<id> form route. The JSON
PATCH /servers/<id> endpoint is retained.

- Native <dialog> modal infra (CSS + ~30 LOC JS, no framework) used for
create forms and delete confirmations.
- Index pages become listing-only: + Create button opens a modal; the
broken blueprint Actions column and inline overlay edit cells are gone.
- Server detail gains a blueprint reassignment form; existing Delete
button now opens a confirmation modal before tearing down the runtime.
- Blueprint detail gains a Delete button + confirmation modal (was
unreachable from the UI before).
- New overlay detail page at /overlays/<id> with edit form, "Used by"
blueprints list, and delete (admin only).
- Server create: port field is now optional; backend auto-assigns the
next free port from LEFT4ME_PORT_RANGE_START/_END (default
27015-27115). 409 on range exhaustion.
- New routes: POST /blueprints/<id>/delete (form sentinel matching
overlays pattern), POST /servers/<id> (form-friendly blueprint
reassign), GET /overlays/<id>.
- Server delete operation now redirects to /servers; overlay update
redirects to /overlays/<id>.
Server rename remains unsupported pending an id-vs-name design pass for
l4d2host (the runtime directory is name-keyed; renaming would orphan
files).

The HTTP-only test deployment binds gunicorn to 0.0.0.0:8000 with no TLS
terminator, so a hardcoded SESSION_COOKIE_SECURE=True breaks browser
login. Make it opt-out via env (default True outside TESTING) and set
SESSION_COOKIE_SECURE=false in the generated web.env so the test box
keeps working over HTTP.

- validate instance names at the host lib and web boundary against
[a-z0-9][a-z0-9_-]{0,63} to prevent path traversal via Server.name
- fail-closed on SECRET_KEY: load_config returns None when env unset,
create_app raises if missing or "dev" outside TESTING
- close login timing oracle by hashing a dummy digest when the user
is not found, equalizing response time
- set SESSION_COOKIE_SECURE outside TESTING
- delete_instance tolerates stop_service and fusermount3 failures so
partially-initialized instances clean up without contract breaks;
drops the is_mount() preflight that violated AGENTS.md
- document claim_next_job's single-process assumption
- clarify emit_step contract via docstring
