+  │ We're implementing a new plugin. It should show if the PC may be able to go to sleep right now
+  │ by running `systemd-inhibit --json=short --mode=block --list` and show the current inhibitors.
+  │ KDE's powerdevil does not inhibit sleep or shutdown, it just blocks the system from doing that
+  │ because it does not know when user input happens on the desktop.
+  │
+  │ In addition to showing inhibition state it should be possible to disable sleeping by flipping a
+  │ switch so the dashboard itself inhibits sleep.

+  │ I'm in plan mode, so I'll be working read-only while exploring the codebase to understand the
+  │ plugin system and build a plan for a new sleep inhibitor plugin.

+  │
+  │ Now I have a good understanding of the plugin architecture. Let me check the output format of
+  │ `systemd-inhibit --json=short --list` and think about how to implement sleep inhibition from a
+  │ persistent process.
+  │
+  │ Key design considerations:
+  │
+  │ 1. **Displaying inhibitors**: Run `systemd-inhibit --json=short --list` (actually `--list` alone
+  │ displays the list, and `--json=short` is for the inhibit command... let me think about it.
+  │ Actually, `systemd-inhibit --list` lists active inhibitors. Let me verify: `systemd-inhibit`
+  │ usage:
+  │    - `systemd-inhibit COMMAND...` — runs a command with an inhibitor lock
+  │    - `systemd-inhibit --list` — lists active inhibitor locks
+  │    - `--json=pretty|short|offline` — output as JSON
+  │
+  │    So `systemd-inhibit --json=short --list` should work. Each entry in the JSON array has fields
+  │    like:
+  │    ```json
+  │    {
+  │      "who": "user name",
+  │      "what": "sleep",
+  │      "why": "reason",
+  │      "mode": "block"
+  │    }
+  │    ```
+  │    Actually, the JSON fields for inhibitors listed via systemd-inhibit --json=short --list are:
+  │    `who`, `what`, `why`, `mode`. Let me recall from the systemd docs (INHIBITOR LOCKS):
+  │    `systemd-inhibit --list` shows WHO, WHAT, WHY, MODE. JSON output has those keys.
+  │
+  │ 2. **Creating a persistent inhibitor**: `systemd-inhibit` in COMMAND mode spawns the command and
+  │ holds the lock while it runs. To keep the lock for the lifetime of the dashboard process, the
+  │ natural approach is:
+  │    - Option A: `asyncio.create_subprocess_exec("systemd-inhibit", "--what=sleep",
+  │    "--who=Dashboard", "--why=...", "--mode=block", "sleep", "infinity")` — hmm, that's hacky but
+  │    works: run `systemd-inhibit ... -- shell -c 'sleep infinity'` or `sleep 2147483647`.
+  │    - Option B: Use `systemd-inhibit` in "list" mode... no, that's not it.
+  │    - Option C: Use `loginctl inhibit` — deprecated.
+  │    - Option D: Use `busctl`/D-Bus: `org.freedesktop.login1.Manager.Inhibit` — the proper API,
+  │    holding an fd. Requires a D-Bus session/system bus client. Python stdlib has no D-Bus; could
+  │    shell out to
+  │ … [15945 more chars]

+  │
+  │ The JSON output has rich fields: `who`, `uid`, `user`, `pid`, `comm`, `what`, `why`, `mode`. And
+  │ since `what` can be a colon-separated list like `handle-power-key:handle-suspend-key:...`, we
+  │ need to split on `:` when checking. Also, the `mode` here can be `block`, `delay`, or
+  │ `block-weak` (the newer systemd also has `block-weak` — treat it as block-equivalent? block-weak
+  │ is for things like… it's a mode where the inhibitor is ignored if it's the only one? Let me
+  │ recall: `block-weak` — "the inhibitor is only effective if there are other active inhibitors
+  │ too"? Actually, according to the man page: block-weak: "the lock is only applied if there are
+  │ other locks of the same type"? I'll treat block-weak as block for our determination (or display
+  │ it as-is and only count `block`… hmm). Let's not overthink it; display the mode as-is, and treat
+  │ `block` and `block-weak` as blocking.
+  │
+  │ Also, `sleep infinity` works (rc=124 = force-killed by timeout, as expected).
+  │
+  │ Another interesting point: the `pid` and `comm` fields in the list output — very useful for
+  │ display (and for reaping old locks from our marker: we can filter the list by who, get the pid,
+  │ and kill that pid!). This makes startup cleanup easy: parse the list, find entries where who ==
+  │ our marker, and kill(pid). No pgrep needed.
+  │
+  │ Now, let's check the CSS classes available in the templates and match the UI style. I'll look at

+  │
+  │ Alright, I now have the full picture. Let me lay out a plan.
+  │
+  │ ## Design
+  │
+  │ **Plugin**: `app/plugins/sleep.py`
+  │ - `Plugin(id="sleep", title="Sleep inhibitors", description=..., skeleton_fn=_skeleton)`
+  │ - Router: prefix `/api/plugins/sleep`, with tags `["plugins"]`
+  │   - `GET /state` → render `plugins/sleep_state.html` with the following data:
+  │     - `inhibitors`: a list of dicts from `systemd-inhibit --json=short --list` (parsed with the
+  │     `json` stdlib)
+  │     - `verdict`: "blocked" | "delayed" | "ok"
+  │       - If any inhibitor has `"sleep" in what.split(":")` and mode in ("block", "block-weak"),
+  │       then blocked
+  │       - Otherwise, if there's one with mode == "delay", then delayed
+  │       - Otherwise, ok
+  │     - `error`: a string when the command fails
+  │     - `holding`: bool — whether the dashboard is currently holding its own inhibitor (so the
+  │     state fragment can reflect the switch even after a re-render)
+  │   - `POST /toggle` → flip in-memory state:
+  │     - On: launch `systemd-inhibit --what=sleep --mode=block --who=<marker> --why=<marker> sleep
+  │     infinity` via `asyncio.create_subprocess_exec(start_new_session=True)` and hold a reference
+  │     to it
+  │     - Off: `proc.terminate()`, wait, and if necessary kill the process group (since we used
+  │     start_new_session, we can do os.killpg on the group)
+  │     - Return the full skeleton (`_skeleton`) with a message. This re-renders the switch and
+  │     state (matching the llamacpp pattern)
+  │     - Return errors as a message in the skeleton.
+  │
+  │ - State module-level:
+  │   ```python
+  │   _holder: asyncio.subprocess.Process | None = None
+  │   ```
+  │   Plus an async lock to serialize toggles (double-clicks) — a nice touch: `asyncio.Lock`.
+  │
+  │ - Who marker: something distinctive like `Dashboard (sleep inhibitor)`. It shows up in the list
+  │ as `who`.
+  │
+  │ - Shutdown cleanup: register in lifespan? The plugin router doesn't know about lifespan…
+  │ options:
+  │   - Expose an `async def close()` on the plugin module and call it from `app/main.py`'s lifespan
+  │   shutdown. That means main.py has to know about this plug

+  │
+  │ With this, I've got the full picture. I'll write up the plan.
+  │
+  │ ## Plan
+  │
+  │ ### Overview
+  │ New plugin "Sleep inhibitors" (`app/plugins/sleep.py` + 2 templates + registration + a small
+  │ Plugin lifecycle extension).
+  │
+  │ ### Files
+  │
+  │ 1. **`app/plugins/base.py`** — Extend `Plugin` with lifecycle hooks:
+  │    - `open_fn: Callable[[], Awaitable[None]] | None = field(default=None)` → `async def open()
+  │    -> None` (no-op if None)
+  │    - `close_fn: Callable[[], Awaitable[None]] | None = field(default=None)` → `async def close()
+  │    -> None`
+  │    Needed so the sleep plugin can reap stale locks at startup and release its own lock at
+  │    shutdown. llamacpp stays with None (no-op).
+  │
+  │ 2. **`app/main.py`** — lifespan: on startup, `for p in PLUGINS: await p.open()` (wrap in
+  │ try/except so one plugin's failure doesn't break startup? llamacpp's skeleton errors are handled
+  │ in the index. For open(), a failure shouldn't be fatal — log it and continue. Simple: try/except
+  │ per plugin, print or ignore. Hmm, no logging framework in the codebase — errors surface in
+  │ uvicorn logs. `print`? The codebase has no print. uvicorn's log level is warning. Wrap in
+  │ try/except Exception: pass? Silently swallowing is bad. Use `logging`? Not used anywhere. Let me
+  │ check… the codebase has no logging module. uvicorn outputs tracebacks for unhandled exceptions.
+  │ For robustness, in lifespan: for each plugin try/except Exception → pass (the plugin's own
+  │ endpoint will keep displaying the error state). Actually simpler: don't catch; if open() raises,
+  │ uvicorn's startup fails, which is visible and correct for a misconfigured plugin. Hmm — but a
+  │ transient D-Bus issue at startup (logind not ready when running as a systemd service!) could
+  │ crash the whole dashboard startup. That's a real risk: if dashboard.service starts before logind
+  │ is ready, `systemd-inhibit --list` may fail. So the open() reap should be defensive (never
+  │ raise). And in lifespan, wrap open() calls in try/except Exception to keep startup robust. I'll
+  │ spell this out in the plan.)
+  │    - O
+  │ … [7945 more chars]
+  │
+  │ I've explored the codebase and verified the tooling on this host. Here's the plan.
+  │
+  │ ## Plan: "Sleep inhibitors" plugin
+  │
+  │ ### Context verified on this host
+  │ - `systemd-inhibit --json=short --list` returns an array of objects: `who, uid, user, pid, comm,
+  │ what, why, mode`. `what` can be colon-separated (PowerDevil shows
+  │ `handle-power-key:handle-suspend-key:handle-hibernate-key:handle-lid-switch`), so matching must
+  │ split on `:`.
+  │ - `sleep infinity` is supported (needed to hold a lock for the process lifetime).
+  │ - No new dependencies — `asyncio` subprocess + `json` stdlib, same style as
+  │ `app/systemd/units.py`.
+  │
+  │ ### New/changed files
+  │
+  │ 1. **`app/plugins/sleep.py`** (new) — router `prefix="/api/plugins/sleep"`:
+  │    - `GET /state` → polls `systemd-inhibit --json=short --list` (5 s timeout), computes verdict:
+  │      - **blocked** — any inhibitor with `sleep` in `what` and `mode` in (`block`, `block-weak`)
+  │      - **delayed** — only `mode=delay` sleep inhibitors
+  │      - **ok** otherwise. (`idle` inhibitors are listed but don't affect the verdict — they gate
+  │      auto-idle, not manual sleep.)
+  │    - `POST /toggle` (`on` checkbox field; browser omits it when unchecked) — sets (idempotent)
+  │    dashboard's own inhibitor under an `asyncio.Lock`:
+  │      - on: spawn `systemd-inhibit --what=sleep --mode=block --who="Dashboard (sleep-inhibit)"
+  │      --why="..." sleep infinity` with `start_new_session=True`, keep the process ref
+  │      - off: SIGTERM the process group → wait 3 s → SIGKILL fallback
+  │    - module-level `open()`/`close()` hooks:
+  │      - `open()` (startup): reaps **stale locks** left by a hard-killed dashboard — list
+  │      inhibitors, `os.kill(pid)` entries with our `who` marker (the JSON includes `pid`, so no
+  │      pgrep needed). Never raises (logind may not be ready when started via systemd).
+  │      - `close()` (shutdown): releases the holder, so a normal SIGTERM never leaks the lock.
+  │    - `plugin = Plugin(id="sleep", title="Sleep inhibitors", ...)`.
+  │
+  │ 2. **`app/plugins/base.py`** — add optional `open_fn` / `close_fn` (+ `open()`/`close()` no-op
+  │ methods) to `Plugin`, mirroring `skeleton_fn`.
+  │
+  │ 3. **`app/main.py`** — lifespan: `await p.open()` for each plugin on startup (wrapped in
+  │ try/except so one plugin can't break boot), `await p.close()` on shutdown.
+  │
+  │ 4. **`app/plugins/__init__.py`** — register plugin + router.

+  │ row highlighted; "no active inhibitors" fallback.
+  │
+  │ 7. **`static/css/style.css`** — add `.badge-block` (red), `.badge-delay` (yellow), `.inh-own`

+  │ Both recommended options have been selected:
+  │ 1. In-memory only

+  │
+  │ Now I'll present the final integrated plan. Since the user answered the questions, the plan is

+  │ probably: present the plan, the user exits plan mode, and then I implement. Let me present a
+  │ concise final plan summary including the decisions that have been locked in.
+  │
+  │ Decisions locked in: **in-memory only** switch, **`--what=sleep`** only.
+  │
+  │ ## Final plan
+  │
+  │ **New files**
+  │ - `app/plugins/sleep.py` — plugin + router (`/api/plugins/sleep`):
+  │   - `GET /state` — runs `systemd-inhibit --json=short --list` (5 s timeout), renders inhibitors
+  │   table; verdict from `what` split on `:`: **blocked** (`mode` = block/block-weak) > **delayed**
+  │   (delay) > **ok**
+  │   - `POST /toggle` — idempotent set under `asyncio.Lock`; on → spawn `systemd-inhibit
+  │   --what=sleep --mode=block --who="Dashboard (sleep-inhibit)" --why="..." sleep infinity`
+  │   (`start_new_session=True`), off → SIGTERM group, 3 s wait, SIGKILL fallback; returns full
+  │   skeleton so the switch re-renders
+  │   - `open()` — startup: reap stale locks (list entries with our `who`, `os.kill(pid)`); never
+  │   raises
+  │   - `close()` — shutdown: release holder
+  │ - `templates/plugins/sleep_skeleton.html` — 5 s polling state div + `.chk` checkbox posting to
+  │ `/toggle`, `hx-target="closest .plugin-body"` (llamacpp pattern)
+  │ - `templates/plugins/sleep_state.html` — verdict line (existing `dot-*` classes), notices,
+  │ `.table` (who + `user·pid`, what badges, why, mode badges), own-lock row highlighted,
+  │ empty/error states
+  │
+  │ **Modified files**
+  │ - `app/plugins/base.py` — add optional `open_fn`/`close_fn` + no-op `open()`/`close()` to
+  │ `Plugin`
+  │ - `app/main.py` — lifespan calls `p.open()` on startup (try/except per plugin) and `p.close()`
+  │ on shutdown
+  │ - `app/plugins/__init__.py` — register plugin + router
+  │ - `static/css/style.css` — `.badge-block`, `.badge-delay`, `.inh-own`
+  │ - `README.md` — one-line mention in the Plugins blurb
+  │
+  │ **Verify**: `compileall`, `uvx basedpyright`, restart server, curl `/api/plugins/sleep/state`,
+  │ toggle on/off via curl and confirm the lock appears/vanishes in `systemd-inhibit --list` and the
+  │ verdict flips; SIGKILL-then-restart to confirm stale-lock reaping.
+  │
+  │ Ready to implement — say the word.

+  │
+  │ The user is saying: "delayed can be ignored, only the blocks that are shown in the plugin are
+  │ interesting."
+  │
+  │ Interpretation: In the plugin, delay-mode inhibitors should be ignored/hidden — only display
+  │ block (and block-weak) inhibitors. Therefore:
+  │
+  │ 1. **Verdict**: becomes binary — if any sleep inhibitor with mode block/block-weak exists then
+  │ **blocked**, otherwise **ok**. No "delayed" state.
+  │ 2. **Table**: only display inhibitors whose mode is block (or block-weak)? Or display only
+  │ block-mode sleep inhibitors? Hmm — "only the blocks that are shown in the plugin are
+  │ interesting" — I read this as: within the plugin, only block (mode) inhibitors are interesting.
+  │ So the list should filter to block/block-weak mode entries, and delay-mode entries are not
+  │ displayed at all.
+  │
+  │ Wait, but should the table display all block-mode inhibitors (regardless of what: sleep,
+  │ shutdown, idle, handle-*)? The plugin's focus is sleep. But block-mode inhibitors against
+  │ `handle-lid-switch`/`handle-suspend-key` etc. (like PowerDevil's) also don't block sleep itself
+  │ — they block *handling* of those keys. The user's question is "can the PC go to sleep right now"
+  │ — determined by `what=sleep` block inhibitors.
+  │
+  │ Hmm, but the user is now saying "only the blocks that are shown are interesting" — this changes
+  │ the display: filter the table to only block/block-weak entries (delay is noise). And the
+  │ verdict: blocked if there's a sleep block inhibitor.
+  │
+  │ Should the table display all block-mode entries (regardless of what), or only block entries with
+  │ what=sleep? Two readings:
+  │
+  │ A) Table: all inhibitors with mode in (block, block-weak) — regardless of what. Verdict: based
+  │ only on sleep.
+  │ B) Table: only what=sleep AND mode in (block, block-weak).
+  │
+  │ On this host, the current inhibitors are: NetworkManager (sleep, delay), Realtime Kit (sleep,
+  │ delay), UPower (sleep, delay), PowerDevil (handle-*, block), compositor (sleep, delay). Under
+  │ reading A, only the PowerDevil row is displayed, and the verdict is "sleep allowed
+  │ … [6058 more chars]
+  │
+  │ Understood — delay-mode inhibitors are dropped entirely. Updated plan:
+  │
+  │ ## Final plan (revised)
+  │
+  │ **Display/verdict changes**
+  │ - Table shows **only** `mode` in (`block`, `block-weak`) entries — delay rows are filtered out,
+  │ so on this host only PowerDevil's `handle-*` block row appears today, plus our own lock when the
+  │ switch is on
+  │ - Verdict is binary: **blocked** (any `what=sleep` block/block-weak inhibitor) / **ok** — no
+  │ "delayed" state
+  │ - Own-lock row still highlighted; empty state: "no active blockers — the system may sleep"
+  │
+  │ **New files**
+  │ - `app/plugins/sleep.py` — router `/api/plugins/sleep`:
+  │   - `GET /state` — `systemd-inhibit --json=short --list` (5 s timeout) → filter to
+  │   block/block-weak → verdict from `what` (split on `:`) → render
+  │   - `POST /toggle` — idempotent set under `asyncio.Lock`: on → spawn `systemd-inhibit
+  │   --what=sleep --mode=block --who="Dashboard (sleep-inhibit)" --why="..." sleep infinity`
+  │   (`start_new_session=True`); off → SIGTERM group → 3 s wait → SIGKILL fallback; returns full
+  │   skeleton
+  │   - `open()` — startup reap of stale locks (list entries with our `who`, `os.kill(pid)`), never
+  │   raises; `close()` — release holder on shutdown
+  │ - `templates/plugins/sleep_skeleton.html` — 5 s polling state div + `.chk` checkbox (`hx-post` →
+  │ `/toggle`, swaps `.plugin-body`)
+  │ - `templates/plugins/sleep_state.html` — verdict line (`dot-run`/`dot-failed`), notices,
+  │ `.table` (who + `user·pid`, what badges, why, mode), empty/error states
+  │
+  │ **Modified files**
+  │ - `app/plugins/base.py` — optional `open_fn`/`close_fn` + no-op `open()`/`close()` on `Plugin`
+  │ - `app/main.py` — lifespan: `p.open()` per plugin on startup (try/except), `p.close()` on
+  │ shutdown
+  │ - `app/plugins/__init__.py` — register plugin + router
+  │ - `static/css/style.css` — `.badge-block`, `.inh-own`
+  │ - `README.md` — mention in Plugins blurb
+  │
+  │ **Verify**: `compileall`, `uvx basedpyright`, restart, curl `/api/plugins/sleep/state`, toggle
+  │ on/off via curl (lock appears/vanishes in `systemd-inhibit --list`, verdict flips), SIGKILL →
+  │ restart to confirm reaping.
+  │
+  │ One interpretation to confirm I got right: the table shows **all** block-mode inhibitors
+  │ regardless of `what` (so PowerDevil's `handle-*` block row stays visible, while the verdict only
+  │ reacts to `sleep` blockers). Say the word to start implementing.

+  │ There are 9 errors. Let's look at all the errors (not just the tail). The displayed tail
+  │ contains warnings and 2 errors in sleep.py (lines 87, 9?). Let's grab the full error list — run
+  │ basedpyright and filter to errors only.
+  │
+  │ Main issues:
+  │ 1. `list[dict]` without type arguments → error `reportMissingTypeArgument`. Fix: type the dict.
+  │ Since the JSON structure is somewhat dynamic, define a minimal typed view: make the inhibitor a
+  │ `dict[str, Any]`? pyproject has `reportExplicitAny = false` and `reportAny = false` set, so
+  │ `Any` is allowed without warnings. Using `dict[str, Any]` will cleanly resolve the "partially
+  │ unknown" warnings.
+  │ 2. `_context(...) -> dict` missing type argument → `dict[str, Any]`.
+  │ 3. Lines 141/147: `os.killpg` / `proc.kill()` — "Result of call expression is of type int and is
+  │ not used" → assign to `_`. Note: lines 141/147 — `proc.kill()` (line 141?) and `os.killpid...`.
+  │ Let's confirm: line 141: `proc.kill()` inside the timeout branch; line 147: `os.kill(pid,
+  │ signal.SIGTERM)` inside `_open`. Fix: `_ = proc.kill()`, `_ = os.kill(...)`.
+  │ 4. Line 156: `reportCallInDefaultInitializer` — `field(default=None)`? No wait, line 156 is
+  │ inside the `Plugin(...)` constructor: `skeleton_fn=_skeleton`? No... line 156:35 — let's count.

+  │ Before the change: 12 lines matching "error" (including the summary line "N errors" and cycle
+  │ errors). After the change: 9 errors. So the cycle error existed from the start (12 - 9 = 3 lines
+  │ were eliminated... wait: before the change it was 12 lines containing "error", including the
+  │ final summary line. After the change it's 9, and this also includes the summary line. So the
+  │ existing errors were: cycle×2 + summary + ... hmm, let me count: before the change, the lines
+  │ containing "error" are: cycle 2 lines + probably other errors + "9 errors" summary. Well,
+  │ whatever — the key point: cycle errors exist from the start (2 in the stashed run). And my
+  │ changes "added" 7 new dict errors (the 12 lines before the change included 2 cycles + 9 other
+  │ lines? Let me verify precisely: 12 lines matched in the stashed state. My current state has 9
+  │ lines: cycles 2 + sleep.py 7 + summary = 10? But grep counted 9. Hmm: the lines shown in the
+  │ grep output above are 10 lines (cycle 2 + sleep 7 + summary "9 errors"). Wait, the displayed
+  │ output is:
+  │
+  │ 1. app/__init__.py cycle

+  │
+  │ Confirmed: on a clean tree there are 2 pre-existing "Cycle detected" errors (unrelated to my
+  │ changes). Therefore, the new errors I'm responsible for are only the 7
+  │ `reportMissingTypeArgument` ones in sleep.py. Fix by adding type arguments: use `dict[str, Any]`
+  │ for JSON-derived dicts and for the return type of `_context`.
+  │
+  │ pyproject has reportExplicitAny=false and reportAny=false, so `Any` is clean.
+  │
+  │ Fixes in sleep.py:
+  │ - `async def _list() -> tuple[list[dict[str, Any]], str]:`
+  │ - `data = json.loads(...)` → Any; `[e for e in data if isinstance(e, dict)]` → the elements are
+  │ `dict[Any, Any]`… isinstance(e, dict) narrows to `dict[Unknown, Unknown]`. To get a clean
+  │ `list[dict[str, Any]]`, annotate: `items: list[dict[str, Any]] = [e for e in data if
+  │ isinstance(e, dict)]`? The list comprehension of dict[Unknown,Unknown] assigned to
+  │ list[dict[str,Any]] — since Any is bidirectionally compatible, basedpyright should accept this.
+  │ - `def _verdict(inhibitors: list[dict[str, Any]]) -> str:`
+  │ - `def _rows(inhibitors: list[dict[str, Any]]) -> list[dict[str, Any]]:` — the returned rows are
+  │ homogeneous strings/bools; `list[dict[str, str | bool]]`? Each row: who:str, proc:str, what:str,
+  │ why:str, mode:str, own:bool → `dict[str, str | bool]`. Good.
+  │ - `def _context(...) -> dict[str, Any]:`
+  │ - Also `isinstance(pid, int)` is fine.
+  │ - Unused results: `proc.kill()` → `_ = proc.kill()`; `os.kill(pid, signal.SIGTERM)` → `_ =
+  │ os.kill(...)`.
+  │
+  │ Add `from typing import Any` import.
+  │
+  │ Let's apply the edits.
+  │
+  │ Pre-existing: the 2 cycle errors exist on a clean tree, so only the 7 `dict` generic errors in
+  │ my file are new. Fixing with `dict[str, Any]` typing (Any is allowed per pyproject config):

+  │ Line 143: `await asyncio.wait_for(p.wait(), 3)` — hmm, the warning is "Result of call expression
+  │ is of type int and is not used" — p.wait() is... no wait, `asyncio.wait_for(...)` returns a
+  │ coroutine result. Actually the warning is about line 143 column 9, line 149 column 9 — those are
+  │ the `await p.wait()` calls. `p.wait()` returns int (the return code), and it's unused → warning.
+  │ This is a stylistic warning (the existing codebase also has similar warnings, e.g. llamacpp).
+  │ But let's clean it up: `_ = await asyncio.wait_for(p.wait(), 3)` and `_ = await p.wait()`. And
+  │ line 48 column 42: the `e` inside the list comprehension `[e for e in data if isinstance(e,
+  │ dict)]` — `data` comes from json.loads → Any... "Type of e is unknown" — minor. Can be
+  │ suppressed with a cast, but the warnings are acceptable in this codebase (before my changes
+  │ there were 12 warnings, now 16; the existing code has the same kind of warnings, e.g. Form's
+  │ default initializer warning). The two `wait()` ones are cheap to fix, so I'll fix them to keep

+  │ reverts to "sleep allowed"

+  │ `sleep infinity` have been orphaned?
+  │
+  │ No wait — killpg sends SIGTERM to the entire process group (session). The child process `sleep

+  │ have died too. Let me check what this 1 process actually is. Maybe pgrep -f "sleep infinity" is
+  │ matching something else... or the child process is a zombie? Let me investigate.
+  │
+  │ Toggle off works and the lock is gone — but `pgrep` shows a possible orphaned `sleep infinity`.

+  │ False alarm — the earlier `pgrep -f "sleep infinity" | wc -l` matching 1 was probably either
+  │ pgrep matching its own temporary shell (the bash -c wrapper that contains that string), or a
+  │ race condition where the process was in the middle of terminating. Currently `pgrep -af "sleep

+  │ The reap (cleanup) on startup is working correctly:

+  │ error suggests that the new server failed to bind because the old one was still holding the

+  │
+  │ Wait, sequence of events:
+  │ 1. `kill -9 $PID` — killed the old server. But the log shows bind error...
+  │ 2. Actually — the kill -9 test command: `PID=$(pgrep -f "python main\.py" | head -1)` — pgrep
+  │ matches "python main.py". Could there have been two python main.py processes? No...
+  │
+  │ Hmm, let me think: /tmp/dash.log was truncated by the restart's `>` redirect. The bind error is
+  │ in that log, meaning the process that just started hit "address already in use". But the
+  │ endpoint is returning 200 — meaning some server is listening. Which one?
+  │
+  │ Possibility: the old server survived the kill? No — the count after the kill showed the lock was

+  │ ran). And now the endpoint is working.
+  │
+  │ Another possibility: `pgrep -f "python main\.py"` matched the first process — but `uv run python
+  │ main.py` spawns `uv` (the parent) + `python main.py` (the child)? Actually, `uv run python
+  │ main.py` — uv execs python; the process tree might be `uv run ...` → `python main.py`. pgrep -f
+  │ "python main\.py" matches both the `uv run python main.py` line and the child `python main.py`
+  │ line. `head -1` picks the first (probably the uv parent). kill -9 on the uv parent → the child
+  │ python main.py might survive (orphaned, still holding port 8501!). Then the new server fails to
+  │ bind (address in use), but the old orphaned server is still serving.

+  │
+  │ There's exactly one server: PID 137165 (`python3 main.py`) is holding port 8501. So what
+  │ happened with the bind error?
+  │
+  │ Timeline:
+  │ 1. In the kill -9 test, I killed `pgrep -f "python main\.py" | head -1`. The process tree of
+  │ `setsid nohup uv run python main.py`: `uv` is probably exec'd into python (uv run replaces
+  │ itself? no—`uv run` spawns the managed process; the command line shown earlier for PID 137165 is
+  │ `.venv/bin/python3 main.py`). Hmm, but the command line of `uv run python main.py`—pgrep -f
+  │ "python main\.py" should match a `uv run python main.py` process if uv keeps the child process
+  │ in a separate form.
+  │
+  │ Wait, PID 137165: which start is this? The first restart created some PID; then I killed
+  │ something; then I started again (that start logged the bind error and died). So the currently
+  │ running 137165 = the server from the first restart, which survived my kill -9??
+  │
+  │ That would mean the `kill -9 "$PID"` in the reap test killed the wrong PID (e.g., the `uv`
+  │ wrapper, not python3)—the python3 child process got orphaned and survived, still holding the
+  │ port and the lock's... no wait, the lock was held by systemd-inhibit's child process, not the
+  │ server.
+  │
+  │ So the reap test was invalid?! The lock disappeared "after restart"—but what actually reaped it
+  │ was... hmm, wait. Let me think again.
+  │
+  │ Actually wait: if kill -9 killed only the `uv` wrapper (parent), python3 main.py survived (still
+  │ serving). The new `setsid nohup uv run python main.py` failed to bind → exited → its lifespan
+  │ never ran → no reaping. So who released the old systemd-inhibit lock?
+  │
+  │ Possibility: the `pgrep -f "python main\.py"` in the kill command matched `head -1`... pgrep's
+  │ output order is PID order. The uv wrapper's PID should be smaller than python3's child PID
+  │ (parent spawns child). So head -1 = uv wrapper. kill -9 uv → python3 orphaned, survives.
+  │
+  │ But then, why did the lock count drop to 0? Let me re-check the output of the reap test: "after
+  │ restart (expect 0): 0". And pgrep -af "sleep infinity" showed
+  │ … [9931 more chars]
+  │
+  │ I found one server running (PID 137165), but there's a bind error in the log that I need to

+  │ The server that's running (137165) was started at 21:23:26, and its parent process is 1163 (not
+  │ the uv wrapper from the first restart... need to check what 1163 is). And /tmp/dash.log only
+  │ contains the bind error — meaning the last redirect to /tmp/dash.log was from the failed second
+  │ startup, and the log of the first startup was overwritten.
+  │
+  │ Wait a minute, actually: the second startup command truncated /tmp/dash.log with `>`. The log
+  │ only has the bind error. So the current server (137165, PPID 1163) is not from the second
+  │ startup (that one died). It's... from the first restart? Its log was truncated by the second
+  │ startup's redirect (both use /tmp/dash.log — the second startup's `>` truncation wipes out the
+  │ first server's log, but the first server still has the fd open and writes continue... hmm, the
+  │ first server's fd is offset-based, so it would end up writing after the truncation with a sparse
+  │ gap).
+  │
+  │ So then, what is PPID 1163? Let's check. And when was the first restart? Let me try to
+  │ reconstruct the times: the first restart command was executed, then the toggle test, then the
+  │ SIGKILL test, then the second restart. If 137165 is from the first restart, then it survived the
+  │ SIGKILL (my kill -9 targeted the uv wrapper, not the python3 — as I analyzed, pgrep -f "python
+  │ main\.py" doesn't match "python3 main.py").
+  │
+  │ Wait, but that's exactly what the AGENTS.md recipe does: `PID=$(pgrep -f "python main\.py" |
+  │ head -1)` — for the purpose of restarting the dev server. If the process's cmdline is "uv run
+  │ python main.py", this matches the uv wrapper. Killing the uv wrapper orphans the python3 child
+  │ process... unless uv gets exec'd. Hmm, but wait: does `uv run python main.py` leave a long-lived
+  │ "uv" process? `uv run` → looks for the venv → execs? I thought uv run spawns the command as a
+  │ child process (it needs to manage environment variables and, in some cases, tool installs). But

+  │
+  │ The parent of PID 137165 (python3 main.py) is 1163, i.e., `systemd --user`! And the start time
+  │ is 21:23:26. So this python3 process was reparented to systemd --user (its real parent died).
+  │
+  │ So here's the story: this is a server from the first restart. Its `uv run` wrapper (and setsid)
+  │ got killed by the `kill -9` in my reap test, and python3 got orphaned → reparented to systemd
+  │ --user.
+  │
+  │ So what my "SIGKILL test" actually killed was the uv wrapper, not the dashboard process. And the
+  │ second restart attempt failed to bind (because the old dashboard was still holding the port).
+  │
+  │ So then, who reaped the orphaned systemd-inhibit lock? Hmm, wait — if the dashboard (137165)
+  │ never restarted, then its open() never re-ran...
+  │
+  │ Wait. Actually, let me reconsider. Was 137165 really the first server? First restart: `setsid
+  │ nohup uv run python main.py > /tmp/dash.log`. uv run → creates python3 child process. When I
+  │ killed in the reap test, what did pgrep match?
+  │
+  │ `pgrep -f "python main\.py"`:
+  │ - "uv run python main.py" (A_uv) — matches
+  │ - "setsid nohup uv run python main.py" — did this still exist? setsid forks and the parent
+  │ exits. So, no.
+  │ - ".venv/bin/python3 main.py" — "python main.py" is not a substring of "python3 main.py" →
+  │ doesn't match.
+  │
+  │ So the kill -9 hit A_uv (uv wrapper). A_py (137165) got orphaned and survived. ✓ Consistent with
+  │ current state (PPID 1163 = systemd --user, orphan reparenting).
+  │
+  │ Now, the lock mystery: after the second (failed) restart, the lock count = 0. The lock-holding
+  │ processes were 137507 (systemd-inhibit) + 137513 (sleep infinity).
+  │
+  │ Ah, wait. I think I finally get it! `uv run` — when uv is killed... no. Hmm.
+  │
+  │ Let me think about `systemd-inhibit`'s behavior: `systemd-inhibit` creates an inhibitor lock via
+  │ D-Bus (the fd is held by the systemd-inhibit process) and execs/launches the command. Actually,
+  │ does systemd-inhibit `exec` the command, or fork? The man page says "executes a command and
+  │ holds an inhibitor lock during its execution." If it forks the chil
+  │ … [5623 more chars]
+  │
+  │ The situation has become clear: the earlier `kill -9` was only hitting the `uv` wrapper (because
+  │ `pgrep -f "python main\.py"` doesn't match `python3 main.py`), so the dashboard survived, and
+  │ the second startup failed to bind. As a result, the reap (reaping) test was invalid. I'll redo
+  │ it correctly, this time killing the actual `python3` PID:

+  │ `POST /toggle` spawns `systemd-inhibit --what=sleep --mode=block ... sleep infinity` in its own
+  │ session (killpg to release); `open()` reaps stale locks by `who` marker at startup, `close()`
+  │ releases on shutdown
+  │ - `templates/plugins/sleep_{skeleton,state}.html` — 5 s polling, verdict line, checkbox switch
+  │ (inside the polling region so it self-heals if the lock dies externally), inhibitor table with
+  │ the dashboard's own row highlighted
+  │ - `app/plugins/base.py` + `app/main.py` — optional `open`/`close` lifecycle hooks run from app
+  │ lifespan
+  │ - CSS: `.badge-block`, `.inh-own`; README/AGENTS updated
+  │
+  │ **Verified on the running server**
+  │ - delay-mode locks (NetworkManager, UPower, …) hidden; PowerDevil's `handle-*` block shown;
+  │ verdict **sleep allowed**
