The `\b` word boundary anchor prevents the optional minus from ever
matching from positions where signed numbers naturally appear (` -1`,
`(-1`, `=-1` all word-boundary-from-non-word and the `-?` fires zero
chars). Negative numbers are tokenised via the operator class instead,
which is the consistent behaviour the grammar already exhibits.
Plan source block updated to match so a fresh regeneration produces the
same file.

Five token classes (comment, string, keyword, number, identifier) plus
operators. Purely visual highlighting; no semantic validation of cvar
names or values.

Brings codejar.js to parity with prism.js, which already carries a
self-documenting header. The README also now records *why* the
unminified source form was chosen: CSP rules out runtime sourcemap
loading from a CDN, so debuggability lives in the vendored bytes.
SHA256 column updated to match the new file content.
Addresses Minor #1 + #2 from the Task 1 code review.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Self-host the editor dependencies under /static/vendor/ since the strict
CSP forbids CDN loading. README records source URLs, versions, and
SHA256s for each file.
Adds a UtcDateTime TypeDecorator (models.py) that enforces aware-UTC on
write and stamps tzinfo=UTC on read. Replaces 26 DateTime column
declarations. Removes 5 production sites that defensively stripped tzinfo
to match SQLite's lossy round-trip. auth.py now coerces legacy session
cookies upward (stamp UTC on parsed naive marker) instead of stripping
live aware markers downward.
The change is Python-side only: UtcDateTime.impl = DateTime, so DDL and
emitted SQL are unchanged. No Alembic migration needed.
Adds 2 unit tests in test_models.py pinning the decorator's contract
independently of the column declarations.
The three deliberately-naive test_timeago.py fixtures (lines 67, 73, 113)
remain naive on purpose -- they exercise _ensure_utc's normalize-up path
at the public filter boundary, which stays as belt-and-braces defense.

Drops .replace(tzinfo=None) from 8 fixture sites that mirrored the
production-side strip convention. Two of these (test_live_state_poller.py
test_new_player_opens_session_with_backfilled_join, test_models.py
test_user_has_password_changed_at_default) now fail with TypeError when
comparing aware in-memory values against naive DB reads -- that failure
is intentional and describes the contract commit 2 must satisfy:
DB-sourced datetimes return aware UTC.
The remaining 6 sites were already cosmetic (fixture-seed only, no
aware-vs-DB comparison) but are flipped here so future authors write
aware fixtures.
The three deliberately-naive sites in test_timeago.py (lines 67, 73,
113) are LEFT untouched -- they exercise _ensure_utc's normalize-up
path and are feature tests, not workarounds.

Steam serves workshop preview images from images.steamusercontent.com,

After the timeago migration, the live-state template no longer reads
'now' — it computes relative labels through the filter, which derives
its own reference time.

Drop the inline humanize_delta imports and string-precomputation; pass
the raw datetime as latest_job_at / latest_build_at and let the

Migrate from pip-install-e + setuptools to a uv workspace with a
committed uv.lock for deterministic deps. Switch both members to
hatchling, and move package sources into nested standard layout
(l4d2host/l4d2host/, l4d2web/l4d2web/) so builds work from a
read-only source tree — setuptools wrote egg-info to source under
the old layout, which broke uv sync on the root-owned /opt/left4me/src.
Local dev install: `pip install -e ./l4d2host -e ./l4d2web` -> `uv sync`.
.envrc switches from `layout python python3.13` to `use uv`. Python
pinned to 3.13 via .python-version.
l4d2web now declares its cross-dep on l4d2host explicitly via
[tool.uv.sources] (workspace = true). l4d2web/alembic.ini and
l4d2web/alembic/ stay at the project root (standard alembic layout).
Test fixes:
- tests/__init__.py added to both test dirs so pytest doesn't shadow
l4d2host as a namespace package via outer-dir walk.
- 3 CWD-relative paths in tests (l4d2web/static/css/{tokens,layout}.css
and js/sse.js) anchored to Path(__file__) so they survive layout
changes.
- Two test_install.py tests now monkeypatch HOME to tmp_path so they
stop silently mutating ~/.steam/sdk32 on every run.
628 tests pass under sandboxed `uv run pytest`.
Per docs/superpowers/plans/2026-05-15-uv-workspace-execution.md;
prereq for the ckn-bw bundle's uv-sync action (queued).

The live-state grid renders player avatars as <img src="https://avatars.steamstatic.com/...">,
but the CSP img-src directive was `'self' data:` — so the browser
silently blocked every avatar load, leaving placeholder circles in
place. The DB cache and Steam API path were both healthy; only the
browser-side load was blocked.
Use the wildcard *.steamstatic.com host-source rather than pinning a
single hostname: Steam rotates avatars across steamcdn-a.akamaihd.net,
avatars.akamai/cloudflare/fastly.steamstatic.com over time, and a
single-hostname allowlist would re-break on the next shuffle.
Test now pins img-src explicitly — the previous assertions only
checked default-src/frame-ancestors/form-action, so a regression of
this exact line would have silently passed.

The hardening refactor that just landed closes the same-uid attack
surface (FS view, ptrace, /proc visibility, signals) for the web +
gameserver units via systemd directives plus system-wide
kernel.yama.ptrace_scope=2. Keeping the script-sandbox on a separate
uid was the inconsistent half-step — defense-in-depth only, with
build-time-idmap complexity attached. One principle wins: harden
once, share the uid.
scripts/libexec/left4me-script-sandbox: drop the idmap block (uid
lookups, STAGING setup, cleanup_staging trap, mount --bind
--map-users), switch User=/Group= to left4me, point BindPaths at
\$OVERLAY_DIR directly. Header comment updated to reflect
hardening-not-uid as the same-uid defense. nsenter self-wrap kept —
it's about mount-namespace escape, not uid.
Tests + comments + companion docs updated. Build-time-idmap and
overlay-idmap plans marked SUPERSEDED; user-uid-split spec revised
to "1 user is correct"; one-line update notes on the hardening
specs and the build-overlay-unit-design.
Companion ckn-bw commit removes the l4d2-sandbox user + group and
tightens /var/lib/left4me from 0711 → 0755 (the traverse-only mode
was specifically for the sandbox uid).
Janitorial item 6 in 2026-05-15-janitorial-cleanup.md. The v1 sandbox
design (2026-05-08-l4d2-script-overlays-design.md) was approved
2026-05-08 and superseded the same day by the v2 systemd-only design
(2026-05-08-l4d2-script-sandbox-v2-systemd.md). The current
left4me-script-sandbox helper uses systemd-run in service-unit mode;
no bwrap binary is invoked. The v1 spec still described bubblewrap as
the engine.
- v1 spec gets a top-of-file banner pointing at v2 as the supersede.
Body preserved; the rest of the v1 design (overlay-type unification,
resource caps, helper auth) is still valid — only the sandbox engine
changed.
- l4d2web/services/overlay_builders.py: ScriptBuilder docstring
"bubblewrap + systemd-run" → "hardened systemd-run transient
service" (the as-built reality).
- scripts/tests/test_script_sandbox.py: stray "/bwrap" in a comment
cleaned up. Negative regression assertions (`assert "bwrap" not in
text`) intentionally retained as the guard against accidental
re-introduction.
- Plan docs left untouched (historical action snapshots).

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)
- pendingCommand captured in htmx:beforeRequest (not requestConfig).
- ensureLoaded shares a single inflight Promise across concurrent calls.
- Document why synthetic null-id entries are safe in the cache.

- _console_line.html: command + reply, error variant, "(no reply)" placeholder.

Firefox and Safari defer lazy images by one paint cycle even when cached,

in-viewport and cached after the first poll, so lazy loading has no benefit.

64x64 avatarmedium looked soft on high-DPI screens. Switching the
GetPlayerSummaries field to avatarfull (184x184) and constraining
display size to 64px via .live-state .avatar gives sharp rendering on
retina/4k panels at the cost of a slightly larger CDN fetch (still
hot-linked, so no proxying cost).
Also adds the previously-missing CSS for the live-state player grid:
avatar+name+meta arranged in a tight 2-column grid per card, link
spans the avatar+name so the meta stays non-interactive.
