A 20-attempts-per-60s budget keyed by IP doesn't slow a distributed brute force that rotates source IPs. Add a parallel per-username bucket with the same threshold so a single account can't burn through more than 20 failed logins/min regardless of where they come from. Empty usernames aren't bucketed (would DoS the anonymous 401 path). Successful login clears both buckets.
_load_files_overlay docs already promised "owner or admin" for mutations, but the check only filtered by overlay.type — system overlays (user_id IS NULL) were writable by any logged-in user. Add the explicit 403 for non-admins; read-only routes remain open across all overlay types.
Mirror the delete-route last-admin guard on /admin/users/<id>/deactivate so a future auth-model change (service accounts bypassing require_admin, etc.) can't accidentally lock out the system.
- login_user clears any pre-login session state before stamping user_id/pw_changed_at/admin so a fixated cookie value cannot smuggle data past the login boundary
- logout_user now session.clear()s instead of only popping user_id, removing leftover pw_changed_at/admin markers
- CSRF token comparison uses hmac.compare_digest
- load_current_user rejects sessions where the stamped admin flag no longer matches the user row, preventing a demoted admin from retaining elevated access until next password change (backward-compatible: sessions issued pre-upgrade lack the marker and pass through until next login)
- ?limit clamp test now actually verifies the clamp instead of just
passing through 5 rows.
- Single is_error assignment per branch, single db.add path.

- POST /servers/<id>/console runs a command via rcon.execute_command and
persists every outcome (success / empty / error) to command_history.
- GET /servers/<id>/console/history returns paginated newest-first JSON
for client-side up-arrow recall.
- server_detail() now passes the last 50 history rows as console_history
for server-side replay on page load.
- 404 on ownership mismatch — no admin override.

HTMX's hx-trigger="every Ns" syntax does not accept fractional seconds —
a config override like 7.5 would render every 7.5s and silently break
auto-refresh. Floor to int with a 1s minimum.

HTMX-refreshed /servers/<id>/live-state fragment renders snapshot

Catch only requests.RequestException in refresh_overlay so that
server-side data errors (e.g., ValueError) bubble up as 500 rather
than being disguised as a 502 "steam api error". Update the 502 test to
use a real requests exception, add a sibling test that verifies
non-requests exceptions propagate, and explicitly assert that refresh
enqueues a build_overlay job even when Steam returns no entries.

POST /overlays/{id}/refresh lets the overlay owner (or any admin)
re-fetch fresh Steam metadata for all items and enqueue a rebuild.

Verifies that on a successful change the digest rotates, the
password_changed_at advances, this session keeps working with the
re-stamped marker, and a parallel session forged from the
pre-change marker is rejected by load_current_user.
profile_password_change now writes a naive password_changed_at so
the in-memory marker matches what SQLite returns on next read.

Implements the change-password endpoint:
- Per-IP rate limit reusing services/rate_limit
- Required fields, mismatched-confirm, policy, wrong-current
branches each redirect with a specific ?error= key
- Rotates digest + password_changed_at, then re-stamps the
current session marker so this browser stays logged in
while other sessions get rejected by load_current_user

Three new POST endpoints on the existing admin blueprint, all guarded
by @require_admin and CSRF (per the global before_request hook):
/admin/users/<id>/deactivate flips active=False (refuses self)
/admin/users/<id>/activate flips active=True
/admin/users/<id>/delete hard delete with safeties:
- refuses self-delete
- refuses delete-of-the-last-admin
- refuses if the user owns Servers, Blueprints, or custom
Overlays (operator deletes those first via existing UIs)
- nulls out Job.user_id (jobs stay as audit trail; FK is nullable)
admin_users.html grows an Active column + an Actions column with the
appropriate button per row (none for self, Deactivate/Activate
toggle, Delete-with-confirmation modal). Modal pattern mirrors
blueprint_detail.html (same modal-close/modal-open data attrs,
csrf_token hidden field).
Refusal responses are 409 with a plain-text body (matches the
blueprint-in-use refusal at blueprint_routes.py:182). No flash
infrastructure introduced; consistent with the rest of the codebase.
All 367 existing tests still pass.
Two-pronged enforcement so deactivation has effect both for fresh
logins and already-issued sessions:
- load_current_user(): treat User with active=False as logged-out
(sets g.user=None). Existing sessions stop working immediately.
- login(): include `not user.active` in the existing 401 condition,
so deactivated accounts get the same "invalid credentials"
response as wrong-password / unknown-user — no timing oracle for
deactivation status.
Tests still green (12/12 in test_auth.py).
Adds Overlay.type='files' whose source-of-truth IS the overlay directory
itself. Users can:
* upload arbitrary files / whole folders by dragging from the OS onto a
folder row in the file tree (one POST per file, queue with
concurrency 3, per-file progress in a floating Uploads panel)
* move via drag-and-drop inside the tree (same gesture, source
distinguishes; refuses cycles)
* create / edit / rename / replace through a single editor modal
(text flavor for editable files, binary flavor with replace-upload
for everything else; filename input is the rename surface)
* mkdir empty folders (slashes allowed for nested intermediates)
* stream a folder as a zip download
* delete files and empty folders
Backend is type-agnostic past the new files_routes endpoints, so the
existing mount / spec / overlayfs / expose_server_cfg pipeline is reused
unchanged. is_editable gates the row's edit affordance and the /save
content rules. Three new safe-resolve helpers (write/delete/move) cover
the new operations with the same anchor-and-resolve pattern as listing
and download. FilesBuilder is a no-op so the build subsystem can
dispatch uniformly.
Spec: docs/superpowers/specs/2026-05-09-files-overlay-design.md

Adds a /servers/<id>/files/download route mirroring the overlay download
endpoint. Same safety rules: real-path must resolve under LEFT4ME_ROOT
(merged view threads through `installation/` and overlay layers, all
already inside the root). The server file-tree partial now renders
download links.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Drops the inline Name input from the blueprint edit form. A Rename link
sits next to Delete in the page footer; clicking opens a one-line modal
that posts to a new POST /blueprints/<id>/rename route. The main edit
form keeps the current name as a hidden input so its full Save still
works unchanged.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds a Files section at the bottom of the server detail page that lists
the kernel-overlayfs merged view at runtime/<server_id>/merged/. Reuses
the overlay file-tree partial via two new template variables:
- files_base_url: parent passes "/overlays/<id>" or "/servers/<id>"
- download_supported: false for servers (runtime holds large game
binaries; no download endpoint), true for overlays (existing behavior)
New service helper safe_resolve_for_server_listing() rejects path
traversal beyond the merged root and returns None when the overlayfs
mount doesn't exist (server never started or just reset).
New route GET /servers/<id>/files?path=<rel> returns the lazy-load
file-tree fragment, gated to the server owner. No download counterpart.

Vendors HTMX 2.0.4 (the prior file was a 1-line stub) and uses it to poll
two new partials on a 2s tick while a job is in flight:
- /servers/<id>/actions → state badge, filtered action buttons,
last-job sentence, live job log (SSE) while a Start/Stop/Reset job
is running. When the job is terminal the partial re-renders without
hx-trigger and polling stops.
- /overlays/<id>/build-status → build state badge, last-build
sentence, live job log while a build_overlay job is running. Same
terminal-state stop behavior.
Server detail restructure:
- Editable name moves out of the page body into a Rename modal
triggered from a link next to Delete in the page footer.
- Compact dl with Port (linked as steam://run/550//+connect <host>:<port>)
and Blueprint.
- Actions row: state badge + state-filtered buttons (start/stop, reset)
+ last-job sentence. Drift warning when desired ≠ actual.
- Recent Jobs table removed.
Overlay detail restructure:
- Single panel, dl Type/Scope, no separate Last build row, no Builds
section.
- Script form gets two compound submits: "Save and build" and
"Save, reset and rebuild". Standalone Rebuild/Wipe gone.
- Build status state badge + last-build sentence under the editor;
action buttons hide while a build is in flight.
- Rename modal in the page footer next to Delete.
sse.js binds on htmx:load (covers initial document and post-swap inserts)

- Detail panels: softer (color-mix --line-soft) border. h2 sub-section
spacing inside a single outer panel. admin and job_detail collapse to
one panel each.
- Color tokens: --color-button-primary / --color-button-danger stay
saturated in dark mode so white text on filled buttons stays readable.
- Site header: transparent, no full-width bar; aligned with panel-content
width. No more sticky.
- Page-level Delete: low-contrast outline button at the page footer
(left side, justify-content flex-start). Save buttons no longer
full-width (.stack > button { justify-self: end }).
- form-actions-inline helper for right-aligned button rows.
- New service: l4d2web.services.timeago.humanize_delta — used by the
upcoming server / overlay live-status partials.
- Server route: POST /servers/<id> renames the server (mirrors the
overlay update pattern, returns 409 on per-user duplicate).
- Overlay route: POST /overlays/<id>/script handles `action` form value
— `save_build` (default) or `save_reset_build` (wipes overlay dir
before queuing build). Redirect lands on /overlays/<id> instead of
the job page so users see the live status.

Each linked overlay gets a checkbox on the blueprint detail page that opts
its server.cfg in as exec server_overlay_<id>. The web app builds the
spec with {path, alias} per overlay and prepends exec server_overlay_<id>
lines to the blueprint config in lowest-overlay-first order. The host
stages those copies in the overlayfs upper layer before mounting (avoids
copy-up writes against a sandbox-uid file). A live preview block above the
Config textarea shows what gets auto-executed.
Schema:
- alembic 0007: BlueprintOverlay.expose_server_cfg BOOLEAN
Spec contract:
- l4d2host OverlayRef(path, alias?). load_spec accepts both bare-string
and {path, alias} entries.
Side effects folded in (same file in l4d2_facade):
- start_server auto-initializes; the manual Initialize step is no longer
needed before Start.
- initialize_server no longer runs blueprint builders — builds happen on
overlay save, not on every server Start.

Replace the per-row checkbox + numeric Order table on the blueprint
detail page with a drag-to-reorder list of selected overlays plus a
native <select> for adding more. Removing uses an × button per row;
the option sorted-inserts back into the dropdown alphabetically.
Native HTML5 drag-and-drop, no library, no JS-disabled fallback.
Server contract is unchanged: each list row owns one hidden
<input name="overlay_ids">, DOM order = submission order, and the
existing fallback_position branch in ordered_overlay_ids_from_form
absorbs the now-omitted overlay_position_<id> fields.

Adds a server-rendered collapsible file tree section to the overlay
detail page so users can verify what their script/workshop overlays
produced and pull individual artifacts (VPKs, configs) without SSH.
HTMX-driven lazy folder expansion with click-to-download via send_file;
symlinks land anywhere under LEFT4ME_ROOT (so workshop addons stream
from the shared cache) but escapes are refused. Same access rule as the
rest of the page (admin or owner). 39 new tests; full web suite green.

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.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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.

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.

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.

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.

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.

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

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.

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.

- 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).

- set SESSION_COOKIE_SECURE outside TESTING
- delete_instance tolerates stop_service and fusermount3 failures so
partially-initialized instances clean up without contract breaks;
