+  │ The journal display repeats output on internal reload. It seems that it appends all journal
+  │ output that is in the buffer to the text field instead of only appending new lines.

+  │ The user is reporting a bug in the journal display. On internal reload (polling), all journal
+  │ output within the buffer is being appended to the text field, instead of only new lines.
+  │
+  │ This is plan mode — I need to investigate the codebase to understand the journal implementation,
+  │ and then propose a plan. Let me look at the journal-related files.
+  │
+  │ Let's explore:
+  │ - `app/journal.py` — the `journalctl -o export` parser with cursors
+  │ - `app/routers/` — journal tab endpoints
+  │ - `templates/` — journal templates
+  │
+  │ Let's read these files.

+  │
+  │ Now I understand the mechanism:
+  │
+  │ - `#journal-log` is a div with `hx-get="/api/journal" hx-trigger="load, every 5s"
+  │ hx-swap="beforeend" hx-include="#journal-filters, #journal-cursor"`
+  │ - The hidden input `#journal-cursor` presumably holds the cursor. The router receives `cursor`
+  │ and uses `--after-cursor` to only fetch entries after that cursor.
+  │
+  │ Bug: "The journal display duplicates output on internal reload. It looks like it appends all the
+  │ journal output in the buffer to the text field, rather than just appending new lines."
+  │
+  │ So on the first load (no cursor), the initial 100 lines are fetched, and next_cursor is
+  │ computed. But where is next_cursor stored? The router renders `journal.html` with `entries` and
+  │ `next_cursor`... but the journal.html template doesn't reference `next_cursor` at all! Let me
+  │ verify — the template only renders entries. So the hidden input `#journal-cursor` is never
+  │ updated. That means every poll sends `cursor=""`, and the router fetches the latest 100 lines
+  │ again and appends them with `beforeend` — duplicating all 100 lines on each 5-second reload.
+  │
+  │ Wait, but is there JS in index.html that updates the cursor? Let me read all of index.html to
+  │ check the JS that updates `#journal-cursor`.

+  │
+  │ Okay, now I understand the whole mechanism. Let me analyze the bug.
+  │
+  │ Flow:
+  │ 1. First load (no cursor): the router fetches the most recent 100 lines, returns them, and the
+  │ JS sets `journalCursor.value` to the cursor of the last line.
+  │ 2. Every 5 seconds: hx-get with the `cursor` parameter. The router calls `journal.tail(cursor,
+  │ ...)`, using `--after-cursor` to fetch entries *after* the cursor. Entries after the cursor are
+  │ appended.
+  │
+  │ Wait a sec — so if the cursor is being tracked correctly, why is the output being repeated?
+  │
+  │ Possible causes of duplication:
+  │
+  │ 1. **Trimming (MAX_LINES) invalidates the cursor**: The JS trims `#journal-log` to 500 lines
+  │ (MAX_LINES = 500). The cursor is tracked from the last line — since it trims from the top, the
+  │ cursor remains valid (points to the last displayed line, which is the most recent). Actually,
+  │ trimming removes old lines, so cursor = cursor of the last line — no problem.
+  │
+  │    Wait, but there's a subtle point: `journalCursor.value = last.dataset.cursor` — if the
+  │    response had 0 new entries (the `entries` list is empty), the template renders nothing,
+  │    `lines` is the existing lines in the DOM, and `last` is the last existing line, whose cursor
+  │    is the same as what's already stored. No problem.
+  │
+  │    Hmm, wait, actually there's a subtle issue: `document.querySelectorAll(".jline")` is scoped
+  │    to `journalLog` — no problem.
+  │
+  │ 2. **`--after-cursor` semantics**: `--after-cursor` shows entries *after* the cursor, not
+  │ including the entry at the cursor position. So no duplication there... except in the case where
+  │ the cursor points to an entry that was already fetched... Let me think about the hide_sudo case:
+  │
+  │    In `tail()`, when `hide_sudo` is on, it fetches `lines * 2` entries and then filters out sudo
+  │    entries. `last_cursor = entries[-1]["cursor"]` — this is the cursor of the last *non-sudo*
+  │    entry after filtering. Okay, that's consistent — the cursor tracks the last *displayed*
+  │    entry.
+  │
+  │ 3. **The real bug**: Let me re-read. "On internal reload, the j

+  │
+  │ Confirming the root cause:
+  │
+  │ - `hr()` reads the input's `name` via `ee(e, "name")` (getAttribute("name")).
+  │ - `cr(a, o, r)` only stores the value when `a != null` (name is non-null).
+  │
+  │ The hidden input in templates/index.html:72 is as follows:
+  │ ```html
+  │ <input type="hidden" id="journal-cursor" value="">
+  │ ```
+  │ Since there's **no `name` attribute**, `ee(e,"name")` returns `null`, and `cr(null, value,
+  │ values)` does nothing. In other words, htmx never sends `cursor` at all, even though
+  │ `hx-include="#journal-cursor"` is present.
+  │
+  │ Therefore, on every 5-second poll, `cursor` arrives as `""` at the server, and the router
+  │ executes `lines = 200 if cursor else 100` → 100 → fetches the latest 100 lines with no
+  │ `--after-cursor` → appends them to `#journal-log` via `hx-swap="beforeend"` → the entire recent
+  │ batch gets duplicated on every internal reload. This matches the user's report exactly.
+  │
+  │ Also, even if `name="cursor"` is added, there's one more thing to consider: the JS trim handling
+  │ (MAX_LINES=500) keeps the cursor from the last line — no problem.
+  │
+  │ Now, are there any other contributing factors or edge cases that should be included in the plan?
+  │
+  │ 1. **Main fix**: Add `name="cursor"` to the hidden input in templates/index.html. This is a
+  │ template-only change (no server restart needed).
+  │
+  │ 2. **Secondary considerations** (should they be included in the plan?):
+  │    - **Race condition**: A filter submission and a scheduled 5-second poll could race with the
+  │    same cursor → the same batch gets appended twice. The submit handler synchronously clears the
+  │    log, but an in-flight poll (hx get) that had already fetched a response with the old cursor
+  │    could arrive after the new batch has been appended, and duplicate lines. htmx doesn't
+  │    automatically cancel in-flight requests… Actually, does htmx cancel the previous request for
+  │    the same element when a new one starts? No — htmx doesn't cancel in-flight requests by
+  │    default; both responses will be swapped. This can cause sporadic duplicates on filter chang

+  │ Definitively confirmed: `fr(e)` returns `false` when `e.name === "" || e.name === null` —
+  │ meaning that in htmx 1.9.12, an input without a `name` attribute is completely skipped. The
+  │ hidden input `<input type="hidden" id="journal-cursor" value="">` at templates/index.html:72 has
+  │ no `name`, so even though it's referenced by `hx-include`, the `cursor` parameter is **never
+  │ sent**.
+  │
+  │ Result: every 5-second poll reaches `/api/journal` with `cursor=""` → `lines = 100` → no
+  │ `--after-cursor` → the latest 100 entries get returned → `hx-swap="beforeend"` appends all of
+  │ them again. Every internal reload duplicates the entire recent batch. Exactly the reported bug.
+  │
+  │ Fix: add `name="cursor"` to the hidden input. Template-only change, no server restart needed
+  │ (per AGENTS.md, templates are auto-reloaded).
+  │
+  │ Now, should I also verify there are no other issues? Let me re-examine the full flow after the
+  │ fix, including the trim logic:
+  │
+  │ - DOM capped at 500 lines (MAX_LINES), cursor read from last line → `--after-cursor` only
+  │ fetches entries newer than the last displayed one. Correct, no duplicates.
+  │ - Filter submit: clears the log + resets cursor → fresh 100-line fetch. Correct.
+  │ - Race condition (optional): while an in-flight poll has already received a response (fetched
+  │ with cursor C1), the user submits a filter → log cleared → new batch appended → stale response
+  │ arrives and gets appended → duplication. Rare, transient. Optional hardening: dedupe in
+  │ `htmx:afterSwap` using the existing `data-cursor` attributes — drop incoming `.jline`s whose
+  │ cursor already exists in the DOM. But watch the ordering: appended lines come at the end, and
+  │ the dedupe set should be built from the lines that existed before the swap. Since the swap
+  │ appends after the existing lines, we can: capture the set of existing cursors before... but in
+  │ afterSwap it's after the swap. Hmm — can we distinguish "old" from "new"? Does htmx add the
+  │ `htmx-added` class to appended elements? `addedClass: "htmx-added"` — yes, htmx adds

+  │
+  │ Interesting — even with a completely fake/stale cursor (different boot id, seqnum 0), journalctl
+  │ didn't error out. It just returned entries (the first 2 entries after the cursor — which, since
+  │ the cursor is extremely old, turned out to be the oldest entries). So a stale cursor after a
+  │ reboot doesn't hard-fail. It either returns entries from after that point (potentially
+  │ re-appending old content once), or returns nothing. Either way it self-recovers. Good — no need
+  │ to handle reboots in the plan.
+  │
+  │ Alright, I'm confident in the analysis:
+  │
+  │ **Root cause**: `templates/index.html:72` — `<input type="hidden" id="journal-cursor" value="">`
+  │ has no `name` attribute. In htmx 1.9.12 (vendored), `fr()` skips inputs with `name == null`, so
+  │ `hx-include="#journal-cursor"` sends nothing. Every 5-second poll reaches the server with
+  │ `cursor=""`, and `/api/journal` always returns the most recent 100 lines, which
+  │ `hx-swap="beforeend"` appends again → the entire batch gets duplicated on every internal reload.
+  │
+  │ **Fix**: Add `name="cursor"` to the hidden input. One-line change to the template, no restart
+  │ needed (templates auto-reload).
+  │
+  │ **Verification**: Restart is not required, but to observe the polling I can curl the endpoint
+  │ with and without a cursor:
+  │ - `curl -s "http://127.0.0.1:8501/api/journal"` → 100 lines
+  │ - Grab the last data-cursor, then `curl -s "http://127.0.0.1:8501/api/journal?cursor=<c>"` →
+  │ only newer lines (0 if the system is quiet)
+  │
+  │ The browser-level check (no duplicates appearing in the UI over ~10–15 seconds) is the real
+  │ verification.
+  │
+  │ **Optional hardening** (present to user as a choice):
+  │ 1. Client-side dedup in `htmx:afterSwap`: discard incoming `.jline.htmx-added` entries whose
+  │ `data-cursor` already exists in the DOM. This defends against race conditions (filter submit vs.
+  │ in-flight poll).
+  │ 2. Server-side: not really needed.
+  │
+  │ Let me write up the plan concisely. Plan mode says I should present a well-formed plan. Keep it
+  │ concise. Ask whether they want the dedup hardening,
+  │ … [800 more chars]
+  │
+  │ Root cause found. Here's the analysis:
+  │
+  │ ## Root cause
+  │
+  │ `templates/index.html:72` — the hidden cursor input has **no `name` attribute**:
+  │
+  │ ```html
+  │ <input type="hidden" id="journal-cursor" value="">
+  │ ```
+  │
+  │ I verified in the vendored htmx 1.9.12 (`static/vendor/htmx.min.js`): its input-collection guard
+  │ `fr()` returns false for any input where `e.name == null`, so `hx-include="#journal-cursor"`
+  │ silently sends **nothing**. The `cursor` param therefore always arrives empty at
+  │ `app/routers/journal.py:18`.
+  │
+  │ Consequences, every 5 s poll:
+  │ - `app/routers/journal.py:23` → `lines = 200 if cursor else 100` → always the "no cursor" path
+  │ (100 lines, no `--after-cursor`)
+  │ - `journal.tail()` (`app/journal.py:76`) re-fetches the latest 100 entries
+  │ - `hx-swap="beforeend"` (`index.html:73`) appends the whole batch again
+  │
+  │ So the JS cursor tracking in `static/js/app.js:148` works fine client-side, but the value never
+  │ reaches the server — exactly the "appends the entire buffer on internal reload" symptom.
+  │
+  │ ## Plan
+  │
+  │ 1. **Fix (1 line, template-only, no server restart needed):** add `name="cursor"` to the hidden
+  │ input at `templates/index.html:72`.
+  │ 2. **Verify:**
+  │    - `curl -s http://127.0.0.1:8501/api/journal` → ~100 lines; grab the last `data-cursor`
+  │    - `curl -s "http://127.0.0.1:8501/api/journal?cursor=<c>"` → only entries newer than that (0
+  │    on a quiet system)
+  │    - Watch the Journal tab in a browser for ~15 s: no repeated batches
+  │    - `uv run python -m compileall -q app` (no Python changes expected, sanity only)
+  │
+  │ I also checked the reboot/stale-cursor edge case: `journalctl --after-cursor` with an old
+  │ boot-id cursor doesn't error (tested), so no extra handling needed.
+  │
+  │ One optional hardening: a rare race remains — submitting the filter form while a 5 s poll is in
+  │ flight can append a stale response after the fresh batch. A ~6-line dedup in the
+  │ `htmx:afterSwap` handler (drop incoming `.jline` whose `data-cursor` already exists in the DOM)
+  │ would cover it.
