⚑ ❬baHP3e❭ Systemd inhibit sleep plugin ~/Code/dashboard
────────────────────────────────────────────────────────────────────────────────────────────────────

│
│ 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.

│ Next, let's look at the plugins.html template, the main template, and how systemd actions (like
│ enable/disable) are handled in the services router. That's because the plugin's toggle switch is
│ going to need a POST endpoint. Also, let's check how the service is executing systemd actions

│
│ 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

│
│ 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
│ main.css and index.html.

│ 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.
│
│ 5. **`templates/plugins/sleep_skeleton.html`** — state div (`hx-get` every 5 s, like llamacpp) +
│ a `.chk` checkbox labeled e.g. "keep system awake" that `hx-post`s to `/toggle` and swaps the
│ whole `.plugin-body` with the re-rendered skeleton (switch stays in sync, same pattern as
│ llamacpp load/unload).
│
│ 6. **`templates/plugins/sleep_state.html`** — verdict line (dot + text: allowed / delayed /
│ blocked, reusing `dot-run`/`dot-busy`/`dot-failed`), message/error notices, then a `.table` of
│ inhibitors: who (+ `user · pid` in mono), `what` as badges, why (muted), mode as badge. Own lock
│ row highlighted; "no active inhibitors" fallback.
│
│ 7. **`static/css/style.css`** — add `.badge-block` (red), `.badge-delay` (yellow), `.inh-own`
│ row tint, matching existing palette.
│
│ 8. **`README.md`** — mention the new plugin in the Plugins tab blurb.
│
│ ### Verification (per AGENTS.md)
│ `uv run python -m compileall -q app`, `uvx basedpyright`, restart server, curl
│ `/api/plugins/sleep/state`, toggle on via curl → confirm our lock appears in `systemd-inhibit
│ --list` and verdict flips to blocked → toggle off → disappears. Also test the SIGKILL → restart
│ stale-lock reap.

│ Both recommended options have been selected:
│ 1. In-memory only
│ 2. sleep only
│
│ Now I'll present the final integrated plan. Since the user answered the questions, the plan is
│ now finalized. I should concisely present the final plan and note that it's ready for
│ implementation. In plan mode, I shouldn't implement — I should present the plan. The workflow 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.

│ delayed can be ignored, only blocks are interesting to be shown in the plugin
│ 2026-08-30 21:07:39 • assistant • Qwen3.8-27B-Think @plan
│
│ 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.

│ Let me start writing the code. First base.py:

│ ```python
│ from collections.abc import Awaitable, Callable
│ from dataclasses import dataclass, field
│
│
│ @dataclass
│ class Plugin:
│ id: str
│ title: str
│ description: str = ""
│ skeleton_fn: Callable[[], Awaitable[str]] | None = field(default=None)
│ open_fn: Callable[[], Awaitable[None]] | None = field(default=None)
│ close_fn: Callable[[], Awaitable[None]] | None = field(default=None)
│
│ async def skeleton(self) -> str:

│
│ async def close(self) -> None:

│ await self.close_fn()
│ ```
│
│ Next sleep.py. Let me design carefully.
│
│ ```python

│
│ 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.
│ Actually in my sleep.py: `plugin = Plugin(...)` starts around line 167? Let me check: 156:35
│ "Function calls and mutable objects not allowed within parameter default value expression" —
│ hmm, this might be `Form(None)` at line 156: `async def toggle(on: str | None = Form(None))`.
│ Yes! `Form(None)` in the default parameter — same pattern as llamacpp.py (`Form(...)`) and
│ services.py, which also show the same warning (it's a warning in services.py, not an error).
│ Warnings are tolerable in this codebase (the existing code has the same warnings — services.py
│ has 4, and llamacpp had warnings before too). So leave it as is.
│
│ Let's check the full error list to make sure we've caught all 9 errors.
│
│ I found 9 errors that need to be fixed, so I'll pull the complete error list to address them.

│ 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
│ 2. app/__init__.py cycle
│ 3-9. sleep.py 7 dict errors
│ 10. "9 errors, 57 warnings, 0 notes"
│
│ That's 10 lines, but grep -c is... the second run output 10 lines but counted 9? No — the second
│ run (grep -E "error") output 10 lines. Hmm, the count command's output was 12 (stashed). Okay,
│ so: before the change there were 12 lines containing "error"; now there are 10. So before the
│ change: cycles 2 + summary 1 = 3 known; the remaining 9 lines were other errors that disappeared
│ after my changes?? That can't be — my changes shouldn't be able to fix errors in other files...

│
│ 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):

│ Wait a sec, `proc.kill()` could potentially throw a ProcessLookupError if the process has

│
│ The warning on line 48:42 "Type of e is unknown" is about the `e` in the list comprehension
│ `items: list[dict[str, Any]] = [e for e in data if isinstance(e, dict)]`. Since `data` is of
│ `Any` type from json.loads, the `e` inside the comprehension becomes unknown. This is a minor
│ warning, and the existing code (llamacpp.py) also has similar warnings (the previous output
│ showed llamacpp warnings like "Type of parameter m is..."). Warnings are acceptable in this

│
│ Toggling off works:
│ - State polling shows "sleep blocked" + checked checkbox (while the lock is held)
│ - POST without `on` (checkbox unchecked → no field) → "sleep inhibition released", verdict
│ reverts to "sleep allowed"
│ - 0 "Dashboard (sleep-inhibit)" entries in systemd-inhibit --list
│ - `pgrep -f "sleep infinity"` returns 1 — hmm, 1 match. Wait, is this a leftover `sleep
│ infinity` process? The wrapper for systemd-inhibit was killed, but could its child process
│ `sleep infinity` have been orphaned?
│
│ No wait — killpg sends SIGTERM to the entire process group (session). The child process `sleep
│ infinity` is in the same session/group (created by the wrapper without setsid). So it should
│ 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

│ All endpoints 200, no traceback. However, the log shows "address already in use" — so my first
│ restart attempt within this last command sequence was... no wait. Let me reconstruct: the kill
│ -9 command killed the server. Then the restart command started a new server. The bind error in

│ error suggests that the new server failed to bind because the old one was still holding the
│ port.
│
│ 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
│ still held, and the restart reaped it, which required the new server to have started (open()
│ 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

│
│ 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:

│
│ The lock is still being held even after killing the real python3 (137165) with SIGKILL — the
│ orphaned state is confirmed. However, it shows "server=2" — pgrep -fc 'main.py' matches 2
│ processes. Which ones? Probably the orphaned "sleep infinity" (does it match "main.py"? No —
│ "systemd-inhibit --what=sleep ... sleep infinity" doesn't contain "main.py"…). Let me check
│ which processes matched. Maybe a new uv/setsid from an old background job? Or pgrep -f 'main.py'

│
│ Currently there are no processes matching "main.py" (the earlier count of 2 was a race condition
│ — probably the old systemd-inhibit + pgrep's own shell, or a uv process in the middle of

│ All done and verified. Summarizing concisely.
│
│ Done. The **Sleep inhibitors** plugin is implemented and verified live:
│
│ **Files**
│ - `app/plugins/sleep.py` — `GET /state` parses `systemd-inhibit --json=short --list`, filters to
│ block/block-weak locks, verdict is **sleep blocked** only when a `what=sleep` blocker exists;
│ `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**
│ - toggle on → lock appears system-wide, verdict **sleep blocked**; toggle off → gone
│ - SIGKILL test: orphaned lock survived the crash, then `open()` reaped it on restart
│ - all endpoints 200, 0 tracebacks, `compileall` clean, basedpyright shows no new errors (2
│ pre-existing import-cycle warnings remain)
