The user is asking for a new plugin "Active Sessions": │ 1. Use `loginctl --json=short list-session` to list currently logged-in users. Only `user` class │ sessions are important. │ 2. Each session needs a "Terminate Session" button that calls `sudo loginctl --json=short │ terminate-session `. │ 3. The list should display session id, user, seat, tty, and idle status. The status bubble │ should depend on the idle state. │ │ I'm in plan mode, read-only. First I need to explore the codebase to understand the plugin │ architecture, then build a plan.

Let me summarize the plan. │ │ Key facts confirmed: │ - The host is systemd 261 (Arch), and `loginctl --json=short list-sessions` returns the │ following: │ `[{"session":"3","uid":1001,"user":"mac","seat":"seat0","leader":1069,"class":"user","tty":"tt │ y1","idle":false,"since":null}, ...]` │ Keys: `session` (string), `uid` (int), `user`, `seat` (str|null), `leader` (int), `class` │ ("user"|"manager"|...), `tty` (str|null), `idle` (bool), `since` (int|null). │ - sudo is NOPASSWD for the dashboard user, and `sudo loginctl terminate-session ` works. │ - Plugin conventions: `app/plugins/.py` has `router = │ APIRouter(prefix="/api/plugins/", tags=["plugins"])`, `_state()`/`_skeleton()` render │ functions, `Plugin(id, title, description, skeleton_fn)`; registered in │ `app/plugins/__init__.py` (PLUGINS + ROUTERS). Templates are │ `templates/plugins/_state.html` + `_skeleton.html`, the skeleton wraps the state │ include in `
`. │ - Actions: POST endpoint that receives form fields via `Annotated[str, Form()]`, module-level │ asyncio.Lock, on failure render `_skeleton(error=...)`, on success render │ `_skeleton(message=...)`; the button uses `hx-post`, `hx-vals`, `hx-target="closest │ .plugin-body" hx-swap="innerHTML"`, and `hx-confirm` for destructive actions (the services tab │ uses hx-confirm). │ - Status bubble: use existing `.dot` classes (dot-run for active, dot-sleep or dot-dead for │ idle) + label text. No CSS changes needed. Or badge. Going with dot + label ("active"/"idle") in │ the status column. │ - Docstring: Google style for every function. │ - Errors are displayed inline and never raised (sleep/lact pattern). │ - The plugins tab in README.md and the "Project layout" list in AGENTS.md enumerate the plugins; │ update both (README lines 83-89, 145; AGENTS.md lines 11, 63-68).

I'll write the plan. There are a few undecided design │ points I should either make judgments on or confirm with the user: │ │ 1. The command the user wrote, `loginctl --json=short list-session`, is actually `list-sessions` │ (plural) — I'll make a note that I'll use the correct plural form. │ 2. "Status bubble" — use the existing badge classes (badge-active green / badge-sleeping blue) │ or a dot. I'll use badges ("bubbles") — they match the wording literally and require no CSS │ changes. │ 3. Polling interval: 5 seconds (matches other plugins). │ 4. Idle: `idle` boolean → "idle" (badge-sleeping) vs "active" (badge-active). │ │ Should I ask the user anything? Possible questions: │ - Confirm `list-sessions` (plural) — trivial, not worth asking. │ - Terminate button label: "terminate" or "Terminate Session"? The user said "Terminate Session" │ button. I'll label it "terminate" to match the codebase's lowercase button style │ (start/stop/set/reload/unload). This is a minor stylistic choice, and the codebase consistently │ uses lowercase buttons. I'll note it in the plan. │ - The sudo command: the user explicitly specified `sudo loginctl --json=short terminate-session │ `. `terminate-session` does not produce JSON output. The `--json=short` flag on │ terminate-session is harmless (does it get accepted? Actually, does loginctl accept --json for │ subcommands that don't produce output? Let me think: `loginctl --json=short terminate-session 3` │ — the global --json option. For terminate-session, the output is empty anyway. Does systemd │ accept --json=short globally even for verbs with no output? I think it's accepted (global │ option), but I'm not 100% sure it doesn't error. Let me test — it's a destructive command │ (terminates a session) — must NOT test with a real session! Test with a fake ID: `sudo loginctl │ --json=short terminate-session 999` → will fail with "Session 999 does not exist" or similar, │ but will confirm the flag is accepted.

So the exact command form the user specified works. │ │ Now I have all the information I need. Let me write the plan. I could ask the user a few │ questions about trivial design decisions, but I think they're all minor and I can just state the │ decisions explicitly in the plan. Plan mode says "ask the user for confirmation on judgment │ calls or when weighing trade-offs." The only substantive trade-off: badge or dot for the status │ bubble. The user said "status bubble" — a badge is the literal bubble, and the existing CSS has │ `badge-active` and `badge-sleeping`. No CSS changes needed. I'll go with badge and note this. No │ need to ask. │ │ I'll present the plan concisely and comprehensively. │ │ I've explored the codebase and verified the environment (systemd 261, passwordless sudo for the │ dashboard user). Here's the plan: │ │ ## Plan: "Active Sessions" plugin │ │ ### Verified facts │ - `loginctl --json=short list-sessions` on this host returns short-key JSON: │ `{"session":"3","uid":1001,"user":"mac","seat":"seat0","leader":1069,"class":"user","tty":"tty │ 1","idle":false,"since":null}` │ (note: the real subcommand is `list-sessions`, plural) │ - `sudo loginctl --json=short terminate-session ` is accepted as-is (tested with a fake id → │ `rc=1`, "No session '999' known"). │ │ ### 1. New file `app/plugins/sessions.py` (mirrors `sleep.py`/`lact.py` conventions) │ - `router = APIRouter(prefix="/api/plugins/sessions", tags=["plugins"])` │ - `async _list() -> tuple[list[dict], str]` — `run_json_async(["loginctl", "--json=short", │ "list-sessions"], timeout=5)`; filter to `class == "user"` only; failures returned as `( [], │ error[:200] )`, never raised. │ - `_rows(entries)` — shape into `{id, user, seat, tty, idle}`; `seat`/`tty` become `—` when │ null/empty; `idle` defaults to `False` if not a bool. │ - `_state(message, error)` / `_skeleton(message, error)` — render the two fragments (skeleton │ passes the same context so the first paint already has data, like sleep). │ - `GET /api/plugins/sessions/state` — poll endpoint. │ - `POST /api/plugins/sessions/terminate` — `session: Annotated[str, Form()]`, guarded by a │ module-level `asyncio.Lock` (same as sleep/lact action endpoints): │ 1. validate id against `^[A-Za-z0-9]+$` → else `_skeleton(error=...)` │ 2. fresh `_list()` to confirm the id exists (also gets the user name for the message) → │ unknown id renders as error │ 3. `run_async(["sudo", "loginctl", "--json=short", "terminate-session", session], timeout=5)`; │ rc ≠ 0 → error fragment; success → `_skeleton(message=f"terminated session {id} ({user})")` │ - `plugin = Plugin(id="sessions", title="Active Sessions", description="...user-class loginctl │ sessions...", skeleton_fn=_skeleton)` │ - Google-style docstrings on every function, matching house style. │ │ ### 2. Templates (no CSS changes needed) │ - `templates/plugins/sessions_state.html` — alert/notice lines, then a `table-wrap` table: **id │ · user · seat · tty · status · actions**. Status bubble uses existing badge classes: `badge │ badge-active` ("active") when not idle, `badge badge-sleeping` ("idle") when idle. Terminate │ button per row: │ `` │ (lowercase label to match existing `start`/`stop`/`set` buttons; `hx-confirm` like the │ services tab) │ Empty state: `no user-class sessions` (muted, like sleep). │ - `templates/plugins/sessions_skeleton.html` — wrapper `
` + `
{% include %}
` (5 s like the other plugins). │ │ ### 3. Registration & docs │ - `app/plugins/__init__.py`: import + append to `PLUGINS` and `ROUTERS`. │ - `README.md`: extend the Plugins bullet and the `plugins/` project-layout line. │ - `AGENTS.md`: extend the tab list (line 11) and the `app/plugins/` architecture note with a │ one-liner for the sessions plugin. │ │ ### 4. Verification │ - `uv run python -m compileall -q app` and `uvx basedpyright` │ - Restart the dev server (the documented pgrep/setsid pattern), then `curl` `/api/plugins` and │ `/api/plugins/sessions/state`; check the fragment contains the new card/table; `grep -c │ Traceback /tmp/dash.log` │ - Terminate path: test only the **error path** (POST a bogus id → "unknown session id" rendered) │ — I will not terminate a real user-class session, since that would log the user out mid-test. │ │ One note: the `idle` field is a JSON boolean on systemd 261 (some versions emit `"IdleHint": │ "yes"/"no"` strings). The parser treats non-bool as not-idle, so it degrades gracefully, but │ it's tailored to this host's format. │ │ Want me to proceed with this? │ │ tokens 32 in 1353 out 43447 cached 0 written $0.0000 stop │ 2026-08-31 01:27:22 • user │ │ start implementation │ 2026-08-31 01:27:22 • assistant • Qwen3.8-27B-Think │ │ The user is asking to start the implementation.

A bare string should work as `_MATCH`... actually, does a journalctl │ positional argument need to be in `FIELD=value` form, or be a plain word for a message match? I │ thought plain words should work ("matches journal messages containing the specified word"? no │ wait — that's `-t`/`--grep`). Actually: journalctl positional arguments are "matches" — │ `FOO=bar` or `+FOO=bar`, and a plain word is... let me think. According to the man page: "To │ match a full message, use MESSAGE=..." — a plain string like `foo` without `=` is invalid unless │ it contains `=`. Right: matches must be `FIELD=VALUE`; bare words are rejected ("Invalid │ argument"). So the dashboard's search box only works with `FIELD=value` patterns (e.g., │ `MESSAGE=queuing` or `_COMM=lact`). This is a quirk of the existing UI, not my concern right │ now. │ │ To verify the fix on live data, use the search as `MESSAGE=queuing`? Hmm, wait — the endpoint │ just appends `search[:200]` to the argument list, so `search=MESSAGE=queuing`... URL-encoding a │ `=` in a query value is fine: `/api/journal?search=MESSAGE%3Dqueuing`. journalctl should match │ the field MESSAGE that contains "queuing". │ │ But wait — do journalctl's field matches work against the raw (binary-encoded) MESSAGE? A │ byte-array MESSAGE is a binary payload, and journald stores the actual byte sequence internally; │ the byte-array encoding is only for JSON output.

To verify the fix on real data, I can just │ fetch pages going back far enough using cursors until I reach the August 8 entries. 80 entries │ in the full journal. Or a simpler, more targeted verification: call `format_entries` directly in │ Python against a real journalctl output that includes byte-array entries — a unit test of the │ exact code path. Combined with the endpoint 200s and no traceback, this should be sufficiently │ solid. │ │ Let's do that: run the actual `journal.tail` (the real function, async) with a large line count │ covering the full journal? `tail` caps fetch at 500 (`min(max(fetch,1),500)`).

The 80 list-MESSAGE entries are spread throughout it — they're │ from August 8 (the timestamp in the decoded message was 2026-08-08), and today is August 31.
