Addresses Critical #1 + Important #2/#3/#4 from the Task 9 code review.
CRITICAL — Tab/Enter were stolen by CodeJar before the popup handler
saw them. CodeJar registers its keydown listener during construction
(line ~159), so it ran first in bubble order: Tab handler
preventDefaulted and inserted 2 spaces, Enter handler preventDefaulted
+ stopPropagation'd (with leading indent), so the popup-accept either
ran on corrupted state or never fired at all. Fix: register the popup
listener with {capture: true} and call stopPropagation on the keys we
own — that way capture phase fires before CodeJar's bubble listener
and the key is fully consumed by the popup while it's visible. Normal
typing (popup hidden) early-returns without stopPropagation, so
CodeJar's tab-indent + enter-preserve-indent still work when there's
no autocomplete to accept.
IMPORTANT — destroy() leaked the popup <ul> into document.body. Each
mount/destroy cycle (e.g. modal close/reopen) left an orphan popup.
Fix: pop.remove() in destroy().
IMPORTANT — async refreshPopup could race in stale renders if the
first keystroke fired the vocab fetch and the second keystroke
captured a different ctx before the fetch resolved. Fix: warm the
cache with a fire-and-forget loadVocab(language) at mount, so the
first user keystroke hits cache. Eliminates the only realistic window
for the race.
IMPORTANT — acceptCompletion's Range.setStart could throw
IndexSizeError on pathological state (caret inside a tokenized span
where the fragment isn't fully upstream). Fix: try/catch the entire
DOM mutation block, log + dismiss on failure. Plus an inline comment
documenting the single-text-node invariant the current grammars hold.
Plan source updated for the capture-phase fix (most important for
future regeneration); the other fixes are smaller and only mirrored
into the actual code.

Vocab loaded lazily from /static/data/<lang>-vocab.json on first
mount, cached in memory. Popup appears when the word fragment before
the caret has >=2 word characters and matches the vocabulary. Prefix
matches rank ahead of substring matches; popup shows up to 8 with
scroll. Up/Down navigate, Tab/Enter accept, Esc dismisses.
acceptCompletion uses instance.jar (not the captured closure) so
runtime jar reassignment via setLanguage stays consistent.
Hand-curated set of high-traffic cvars and commands sourced from the
existing l4d2-server-cvar-reference.md and common SourceMod usage.
Regeneration procedure documented in the file header.
30 cvars + 8 commands.
data-editor-language=bash opts the textarea in; the editor uses
Prism's stock bash grammar (no project-owned bash code).
Partial include sits outside all conditional blocks in the template
so the editor assets load for both script-type and files-type
overlays.
The plan template (and verbatim implementation) listed five of the six
editor asset URLs in the structural test — vendor/prism.css was
omitted. If a future change drops the Prism stylesheet from the
partial, syntax tokens lose their color rules silently and the test
still passes. Add the missing assertion and update the plan to match.
Addresses Minor #1 from the Task 6 code review.

The textarea is preserved as the form field; the editor renders a
contenteditable sibling and mirrors content back on every input. Form
POST contract is untouched (covered by new round-trip test).
Addresses two Minor follow-ups from the Task 4 code review:
- findFilenameInput previously included `body` in its closest() selector,
meaning any "auto" textarea outside a modal would walk all the way up
and pick up the files-editor modal's filename input from elsewhere in
the document. Drop `body` so out-of-modal "auto" usage degrades
cleanly to "plain".
- setValue now dispatches an `input` event on the textarea after
writing, matching the onUpdate mirror. Task 10 wires the files-editor
modal to call setValue when loading file content — without this fix,
textarea-listening code (e.g. unsaved-changes indicators) wouldn't
see programmatic loads. Now setValue and user typing produce the
same observable side effects.
Plan source block updated to match.

Mounts on <textarea data-editor-language>, hides the textarea, renders
content in a contenteditable sibling with Prism highlighting via
CodeJar. Mirrors content back to textarea.value on every input so form
POST and existing JS readers keep working unchanged. Exposes
setValue/setLanguage/getValue on textarea._codeEditor for callers.
Language switch uses tear-down-and-remount because CodeJar captures
its highlighter by closure at construction time and has no API to
swap it on a live instance.

Addresses Important #1 + Minor #2/#3 from the Task 3 re-review:
- --color-bg-popover-active light value: #f3f4f6 → #e5e7eb. The prior
value was within ~1.05:1 luminance of the white surface — keyboard
navigation through the autocomplete list had no visible focus
indicator in light mode. e5e7eb (Tailwind gray-200) clears that.
- Drop dead fallback hexes on the four guaranteed tokens
(--color-string/-keyword/-number/-bg-popover-active). They never
fired post-fix and only produced a dark-mode-only palette if
tokens.css somehow failed to load — i.e. they were misleading.
- Plan source block (Task 3 Step 2) replaced with the post-fix CSS
verbatim + a new Step 2b that documents the tokens.css additions
alongside the editor.css template, so a fresh regeneration
produces the same file.
Deferred: cross-cutting --font-mono token (Minor #4 — would touch 7+
sites outside Task 3's scope).

Addresses Important #1 + #2 from the Task 3 code review:
- Adds --color-string, --color-keyword, --color-number,
--color-bg-popover-active to tokens.css in both the :root and dark
blocks. GitHub-style palette tuned for legibility on each theme's
surface.
- Updates .editor-code to use the same padding tokens, font-family
stack, font-size, and line-height as the existing textarea rule so
the contenteditable doesn't visibly jump when the widget mounts.
- Drops the caret-color override (browser default adapts to system
theme — no token needed).
Plan source block updated to match.

Defines .editor-shell, .editor-code, .editor-popup. Reuses tokens.css
variables where present so the editor matches the site palette.

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.

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
template apply the timeago filter. One fewer code path computing
relative-time strings.

Replaces three bespoke (now - x).total_seconds() expressions with 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.
