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.

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 full journal + │ might have thousands of entries. 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. A + │ 500-line window may not reach them. + │ + │ Alternative: parse the full `sudo journalctl -o json` output with `parse_lines` + + │ `format_entries`, assert that no exceptions occur, and print out one of the decoded byte-array + │ messages.
