# Post-0.1.0 usability backlog

Status: **open, expandable by design.** This document is not a fixed release
plan. It collects items found by actually using qtmaildir after 0.1.0, and it
grows as more turn up. Nothing here is scheduled; picking what ships in a given
release is a separate decision.

Source: usage notes taken while running the app, 2026-08-03.

**Numbers here are this document's own.** The user's own notes were numbered
independently and the two sequences drifted apart once items were split: what
those notes called 12 is item 13 here, and item 14 here (the tag column) was
never in them at all. Items 15 to 17 come from a later pass over the same
notes. Cite these numbers, not the notes', and do not renumber to reconcile.

**The notes are the upstream source and they keep growing.** The user adds to
them while using the app, so this document goes stale on its own. Items 28 to 35
came from one such pass on 2026-08-04 and included two defects that had gone
unrecorded here for a while. Items 39 to 45 came from the 2026-08-05 pass, which
found one more defect (41, a message body silently dropped by the MIME walk) and
one item that cannot be planned at all until the user says where the thing it
manages lives (44). Compare the two at the start of a session; the procedure is
in `CLAUDE.md`.

Numbering is stable. New items append with the next free number and never
renumber, so a note referring to "item 7" keeps meaning the same thing. An item
that is dropped stays in the table marked `dropped` with a one-line reason.

**The status table below is the index of every item; the sections are only the
open ones.** Item 73 moved the done, dropped and postponed sections out to
`2026-08-03-post-0.1.0-usability-closed.md`, which took this file from just over
five thousand lines to under six hundred. Nothing was deleted and nothing was
renumbered: a closed item keeps its row here, with its date and outcome, and its
full Observed/Cause/Approach section is in that file under the same number. Look
there when a row cites evidence you need.

**Items 20 and 53 are both on master since 2026-08-10**, as the card list. Item
20's original presentation, the one the user rejected on sight, is preserved on
the branch `item-20-message-rows` at 029a50e and was never merged; the branch
`card-list` carries the work that was. Any file or line reference in item 20's
entry, now in the closed-items file, points at that PARKED branch, not at
master, where the same lines are unrelated. Item 53 records why the first
attempt was rejected and is worth reading before changing the thread pane again.

## Theme

0.1.0 was built to a spec written by someone who lives in neomutt. The result
is a keyboard-driven reader with almost no visible affordances. The notes below
are, with few exceptions, one complaint restated in several forms: **the app
does not tell the user what it can do, and it does not remember what the user
told it.** Two clusters follow from that:

- **Persistence.** Splitter position, font size, window geometry, and the
  account selection all reset on restart. Each is small on its own and
  aggravating every single launch.
- **Discoverability.** Shortcuts are the only route to most actions, and there
  is no menu bar, no toolbar, and no way to see the key bindings from inside
  the app.

Both clusters are cheap to fix. Neither was an oversight in design so much as a
consequence of specifying the app as "a GUI counterpart to neomutt" and then
taking that too literally.

| 21 | Default shortcuts are not sensible enough | discoverability | S | open |
| 22 | Translatability audit and i18n wiring | correctness | M | **done** 2026-08-15, unreleased; see `specs/2026-08-15-i18n-design.md`. Found eight rule-builder labels that could never be translated in any language, and twenty untranslatable warnings. Ships an Italian translation of all 355 strings |
| 23 | No way to save a search query from the UI | workflow | M | **done** 2026-08-13, shipped in 0.18.0; see `specs/2026-08-13-saved-queries-design.md` |
| 24 | No right-click actions on the thread list | discoverability | S | **done** |
| 25 | No select-all, and bulk actions are undiscoverable | workflow | S | **done** |

| 27 | The UI cannot see a sync it did not start | feedback | S | **done** |
| 28 | Re-adding `unread` counts 2 unsynced changes, not 0 | correctness | S | **done** |
| 29 | Sync button stays enabled during a background sync | feedback | XS | **done** |
| 30 | The blank right pane is wasted space | presentation | M | **done** |
| 31 | The quit prompt has no highlighted default button | discoverability | XS | **done** |
| 32 | Esc does not blank the right pane | workflow | XS | **done** |
| 33 | Status bar messages never expire | feedback | S | **done** |
| 34 | No overview of the Maildir itself | information | M | **done** |
| 35 | No refresh of the thread list after a sync | workflow | M | **done** 2026-08-10; the list now follows a sync on its own |
| 36 | `test_mainwindow` cannot reach the worker | testing | S-M | **done** 2026-08-14, unreleased; see `specs/2026-08-14-mainwindow-worker-fixture-design.md`. `WorkerBackedWindow`, opt-in per test, no production change. Its first use ruled out the simple case of item 66 |
| 37 | The worker stalls on a tag edit made during a background sync | correctness | S | **done** |
| 38 | `test_mainwindow` fails when a real sync holds the lock | testing | XS | **done** |
| 39 | Thread list cannot be sorted by clicking a column header | workflow | S | **dropped** 2026-08-10; the card list has no column headers to click, and 0.13.0 shipped a sort dropdown instead |
| 40 | No live filter over the current view | workflow | M | open |
| 41 | A message whose HTML body carries a `Content-Id` renders blank | correctness | S | **done** |
| 42 | "Syncing..." says nothing about what is being synced | feedback | S | **done** |
| 43 | No "Mark all read" for the current view | workflow | S | **done** |
| 44 | No way to manage the filters applied at sync time | workflow | M | **done** 2026-08-13; see `specs/2026-08-12-tagging-rules-design.md`. Spans this repo and `mailctl` |
| 45 | Two Sync buttons, and only one of them works properly | correctness | S | **done** |
| 46 | `uiStateSurvivesARestart` fails under the offscreen platform | testing | XS | **done** |
| 47 | The query bar looks unfinished, and cannot be cleared by mouse | presentation | XS | **done** |
| 48 | Removing a tag suggests every tag, not the thread's own | workflow | XS | **done** |
| 49 | Sync runs every account regardless of what changed | workflow | M | **done** |
| 50 | Esc blanks the pane but leaves the row selected | workflow | XS | **done** |
| 51 | Clicking a subject scrolls the list sideways | presentation | XS | **done** 2026-08-10; a card is viewport width, so there is nowhere to scroll |
| 52 | `test_querycompleter` fails under Wayland, passes offscreen | testing | XS | **done** |
| 53 | Message rows still read as a table, not as a conversation | presentation | M | **done** 2026-08-10, merged to master as the card list |
| 54 | A cron sync carries the edits but the count still says pending | correctness | S | **done** |
| 55 | In a narrow window the message pane is invisible | presentation | XS | **done** |
| 56 | No action carries an icon, so the toolbar reserves space for nothing | presentation | S | **done** |
| 57 | "Flag" would read better as "Important" or "Starred" | presentation | XS | **done** |
| 58 | `message_zoom` documents a 0.5 to 3.0 range and enforces none of it | correctness | XS | **done** |
| 59 | Archive and Mark all read shipped with the same icon | presentation | XS | **done** |
| 60 | Next thread dead-ends on the last reply of an expanded thread | defect | XS | **done**; already fixed by 5487d58, see the closed-items file |
| 61 | `test_mainwindow` fails intermittently, about 1 run in 20 | testing | S | **done** 2026-08-13; an `init()` fixture points every test at its own lock table |
| 62 | No config option for the date format on a card | presentation | XS | **done** 2026-08-11 |
| 63 | No way to see sent mail, and no filter for it | workflow | M | **done** 2026-08-11; see `specs/2026-08-11-sent-mail-design.md` |
| 64 | The Sync button carries a mailbox icon, not a refresh one | presentation | XS | **done** 2026-08-11 |
| 65 | No full code review and optimization pass | correctness | ? | open, unspecified |
| 66 | Selecting a thread root leaves the message pane blank until a reply has been selected | defect | S | **done** 2026-08-14, unreleased. Not the blank pane it was filed as: the root rendered the CONVERSATION until the thread had been expanded once, then one message. Now always one message, and the conversation view is removed at the user's request. **One case unverified by hand:** the notes also report a single-message `id:` query whose card would not open, which is the same empty-`MessageIdRole` failure and should be gone; confirmed 2026-08-15 as a SEPARATE defect with a different cause, see item 96 |
| 87 | Auto mark-read marks a whole thread, including replies never displayed | defect | S | **done** 2026-08-16, unreleased. Built on 108, which is why it stayed small: the timer tracks a MESSAGE id now, and arms for a reply too, which it never did before |
| 88 | `threadAt(current.row())` answers about the wrong thread for a reply row | defect | M | **done** 2026-08-16, unreleased. The audit found FOUR live sites, not one. `ThreadListModel::threadFor(index)` resolves a reply through its parent; every caller holding a selected index converted, and no `.row()` on a selected index remains in `mainwindow.cpp`. Unblocks 87 |
| 67 | The placeholder pane counts unread, flagged and inbox, but not sent or drafts | information | XS | **done** 2026-08-11, shipped in 0.15.0 |
| 68 | A forwarded subject gets no `passed` tag | workflow | S | open; no subject rule exists, measured 2026-08-11. Decision needed: display mark (XS) or write the flag (S, syncs out) |
| 69 | `passed` and `replied` read as words where every other state is a glyph | presentation | S | **done** 2026-08-11, inside item 70 |
| 70 | Pane icons are a private set where the main window uses the system theme | presentation | M | **done** 2026-08-11; six shipped SVGs |
| 71 | A toolbar action does not sync, so the edit sits until the next cron run | workflow | S | **done** 2026-08-11; 2s default, `auto_sync_delay_ms` |
| 72 | No khard/khal integration | workflow | ? | open, unspecified; the user places it after send, so v2 at the earliest |
| 73 | This backlog is past four thousand lines | maintenance | S | **done** 2026-08-13; 5056 lines to 578, closed sections moved to `2026-08-03-post-0.1.0-usability-closed.md` |
| 74 | "Searching..." keeps claiming a query is running while rows are already arriving | feedback | XS | **done** 2026-08-15, unreleased. The status-bar half only: the bar now counts threads per batch. The cold-cache delay itself was measured in 2026-08-11 and is not fixable here |
| 75 | The tagging rules window forgets its size and its column widths | persistence | S | **done** 2026-08-13, shipped in 0.17.0. The window-kind question is left open, see the closed-items file |
| 76 | Every field in the rules dialog is free text, so a rule is easy to get wrong | workflow | M | **done** 2026-08-13, shipped in 0.17.0. See `specs/2026-08-13-rule-builder-design.md` |
| 77 | No way to see what a rule would collect, in the thread list | workflow | S | **done** 2026-08-13, shipped in 0.17.0 |
| 78 | No way to build a rule from something visible in a message | workflow | S | **dropped** 2026-08-17 at the user's request. Never a defect: item 85 built the road (right-click any value, search it, save the query) and item 81 the last step (a rule from a saved query), so the whole journey is available. This was only a shortcut across it, and the entry had already said to use 85 for a while before deciding which values were worth promoting. Reopen if that use turns up a value worth a one-click rule |
| 80 | A rule with many conditions squeezes the rule list to one visible row | defect | XS | **done** 2026-08-13, shipped in 0.17.0. Follows item 76 |
| 79 | Opening the rules dialog and saving destroys the first rule | defect | XS | **fixed on `rule-builder`** 2026-08-13, unreleased. Shipped in 0.16.0; damaged one real rule, repaired by hand |
| 81 | No way to turn a saved query into a tagging rule | workflow | S | **done** 2026-08-14, unreleased; see `specs/2026-08-14-query-to-rule-design.md` |
| 82 | A saved query cannot be edited, unpinned or deleted from the UI | defect | S | **done** 2026-08-13, shipped in 0.18.0. Right-click offers Edit, Pin/Unpin and Delete |
| 83 | A rule named with spaces is written to the file and dropped by every reader | defect | S | **done** 2026-08-14, unreleased. The name is sanitised into an id, save validates, a bad id loads for repair |
| 84 | A config problem blocks `test_mainwindow` on a modal nobody can dismiss | testing | S | **done** 2026-08-14, unreleased. `showWarnings()` split: the status label stays in the constructor, `main.cpp` raises the modal after `show()` |
| 85 | Nothing on screen can be searched for by right-clicking it | workflow | M | **done** 2026-08-14, unreleased; see `specs/2026-08-14-search-from-message-design.md`. Split from 78; rebuilt the details dialog as rows |
| 86 | A right-click search can replace or narrow, but never exclude | workflow | S | **done** 2026-08-14, unreleased; see `specs/2026-08-14-exclude-from-search-design.md`. Follows 85. The `extend` bool became a `SearchMode` enum across four signatures |
| 89 | A sync moves the list under the user's hands, and the auto-sync skips rather than retries | workflow | XS | **done** 2026-08-15, unreleased. The timer half only: a skipped auto-sync re-arms instead of giving up. The list-churn half is **dropped**, not built: the user resolved it as a mental-model question, an Unread view is SUPPOSED to be volatile |
| 90 | A saved-query button clears the account selection | workflow | S | **folded into 93** 2026-08-15. Not fixed in place: the button that misbehaves stops being a saved query at all. See `specs/2026-08-15-builtin-filters-design.md` |
| 91 | Double-clicking a thread should open it on its own | workflow | S | **done** 2026-08-15, unreleased. The view is always the whole thread, EXPANDED; the pane shows whichever row was double-clicked, so a reply drills to its thread and not to itself. Reuses `recoverStaleThread()` outright |
| 92 | Nothing distinguishes a tag written by a rule from one the user applied | information | M | **postponed** 2026-08-15 at the user's request: "I don't see the utility, so I don't really know how to answer." Needs per-MESSAGE provenance nothing records, a two-repo format change blank on all existing mail. Reopen only if the need appears in use |
| 93 | The query buttons are whatever the user pinned, not a designed set of filters | workflow | M | **done** 2026-08-15, unreleased; see `specs/2026-08-15-builtin-filters-design.md`. Absorbs item 90. Four built-in filters composing with the account dropdown; the user's own queries unpinned, never deleted |
| 95 | A query in the overflow menu cannot be run | defect | XS | **done** 2026-08-15, unreleased. Pre-existing and not caused by 93: the entry's action owned a submenu, and Qt emits no `triggered` for those, so the connection had never fired. Surfaced because 93 moved every query into the menu |
| 94 | `pinned` has nothing left to decide once the buttons are built-in | maintenance | S | open; **blocked on 93**, and deliberately not part of it. A user-visible removal: the row becomes built-ins only and every saved query lives in the menu |
| 96 | A query returning the thread already on display opens onto the placeholder | defect | S | **done** 2026-08-15, unreleased. Split from 66's unverified half, which had a different cause. Reproduced from two screenshots after four measured eliminations |
| 97 | An edit made during a sync is reverted in the list when the sync ends | defect | S | **done** 2026-08-15, unreleased. Found by hand-testing item 89's fix. The sync-end refresh ran BEFORE the held-edit flush, so it read a database that still carried the old tag |
| 98 | "Important" adds the tag but cannot remove it, unlike every other toggle | defect | XS | **done** 2026-08-17, unreleased. Calls `everySelectedRowHasTag()`, as the entry required. Its reply test needed THREE different states (list-first thread, the reply's own thread, the reply) before it could tell the two wrong answers apart; with the reply defaulted to its thread's state the item 105 mutation stayed green, measured |
| 99 | The unread action is labelled "Toggle unread" whichever way it will go | presentation | S | open; depends on 98's toggle shape, and the label is harder than it looks |
| 100 | The message pane offers Back, Forward, Reload and Save page, none of which mean anything | defect | XS | **done** 2026-08-17, unreleased. `MessageView::removeBrowserActions()` filters the standard menu by `pageAction()` POINTER, never by text; `ViewSource` went with them, and stranded separators are swept |
| 101 | Sync is account-aware for edits but not for the account the user is looking at | workflow | S | open; item 49 built the edit half deliberately. Needs a decision, see the entry |
| 102 | The rules table shows no note, so the field explaining a rule is invisible until it is opened | workflow | XS | **done** 2026-08-17, unreleased. A Note column before `ColumnCount`, so the appended Matches column stays last. Found a second defect on the way: `restoreState` REFUSES a header state with a different column count, and the sized flags were being set regardless |
| 103 | What Delete does to mail on the server is undocumented and unverified | clarification | S+M | done; Delete moves to the account trash, with Restore and a stranded-mail cleanup. Section in the closed file |
| 104 | Mail visible in Thunderbird never reaches qtmaildir | defect | ? | open, reported 2026-08-16, cause NOT established. Most likely outside this repo; see the entry before writing code |
| 109 | A root card's own message is invisible to a message-scoped write | defect | S | **done** 2026-08-16, unreleased. Found by hand-testing 108. `applyMessageTagChange` and `messageById` searched only the loaded replies, and a root's message is never among them, so the ORDINARY gesture repainted nothing and wiped the pane's chip row |
| 110 | A card and the message pane show tags belonging to a message's siblings | defect | S | **done** 2026-08-16, unreleased. Found by hand-testing 109 against a real 4-message thread. `ThreadSummary::tags` is notmuch's UNION; a card standing for one message drew it. Also the reason a root card could not repaint at all |
| 111 | A card should show its siblings' tags smaller, not drop them | presentation | S | **done** 2026-08-16, unreleased. The user's own design, from looking at 110's result: own tags full size, the thread's others smaller and muted, so nothing appears to vanish on selection |
| 105 | Acting on a reply changes the counter and nothing on screen | defect | M | **done** 2026-08-16, unreleased. Found by hand-testing 88, and took three passes. FOUR causes: no optimistic update for a message-scoped write, no doomed cue on a reply row, both toggles reading the reply's THREAD state so they were one-way, and the message pane's strip not following a message edit. Also bolds an unread reply, at the user's request |
| 106 | A tag change made on one message during a sync is silently lost | defect | XS | **done** 2026-08-16, unreleased. Found by READING while fixing 105, never reported. `flushHeldEdits` re-sent only thread-scoped edits, so a message-scoped one was shown, counted as pending, and never written |
| 107 | A thread-scoped write leaves the loaded replies showing their old tags | defect | XS | **done** 2026-08-16, unreleased. `applyTagChange` updated the summary only, so marking a thread read left its expanded replies bold |
| 108 | Acting on a thread root means the whole thread, though it displays one message | workflow | M | **done** 2026-08-16, unreleased. `messageScopeFor()` beside `scopeFor()`; five `*_thread` actions in a "Whole thread" submenu on `Ctrl+Alt+<key>`. User-visible: minor bump, `### Upgrading` written |
| 112 | Toggle unread on a whole thread cannot reach "all unread" on a partly-read thread | defect | S | open, found 2026-08-17. A toggle over a UNION has no direction on a mixed thread |
| 113 | No way to see a message's HTML source | information | S | open, 2026-08-17. Chromium's own View source cannot work here; needs our own plain-text dialog. Item 100 removed the dead entry, which was an overreach: the user had not asked for it |
| 114 | Save image is offered on every image and does nothing | defect | S | open, found 2026-08-17 by right-clicking a real image. No `downloadRequested` handler exists anywhere, so the request is emitted and never answered |
| 115 | A copy from the message pane gives no confirmation | presentation | XS | **done** 2026-08-19, unreleased. Four entries report, each naming what it copied; connected to the page's own QActions, so the entry is covered wherever it is triggered from |
| 116 | Copy image copies markup instead of the image | defect | XS | **dropped** 2026-08-17, same day. NOT A DEFECT: `wl-paste --list-types` run immediately after a copy reports `image/png`, `application/x-qt-image` and 30 more image flavours. The clipboard is correct and Chromium is behaving. The earlier "text only" reading was taken minutes late off a clipboard that had been overwritten, and a whole cause was theorised on it |
| 117 | The message pane offers no Select all | workflow | XS | **done** 2026-08-19, unreleased. `addPaneActions()` supplies it. The call site is NOT covered by a test and cannot be: the production menu needs a real context-menu event. Stated in the test rather than faked |
| 118 | No way to empty the trash from inside the app | workflow | S | open, 2026-08-17. **Blocked on 103**, which creates the trash in the first place. Deliberately left out of 103's spec at the user's request rather than squeezed in |
| 119 | The unsynced-changes count cannot be opened to see what it counts | information | S | open, 2026-08-19, from the notes. One of the four things it sums carries no message ids at all, so a list cannot be complete without a change to how the count is kept |

Sizes are rough: XS under an hour, S a sitting, M a session.

## 21. Default shortcuts are not sensible enough

**Observed (user, 2026-08-04):** "improve the default shortcuts to some sensed
defaults."

**Unspecified in detail**, so ask which bindings feel wrong before proposing a
table. What is worth recording is the history, because the defaults have
already moved once and the reasons still constrain any second pass.

**Where the current defaults came from.** 0.1.0 used bare letters. They were
replaced in the 0.2.0 menu work for two reasons that have not gone away: a
single letter cannot be a menu accelerator without claiming that letter
window-wide, and a bare capital such as `N` parses to an unshifted `Key_N`,
which no keystroke emits, so `toggle_unread`, `flag` and `sync` were dead keys
that appeared to be bound. See `KeyMap::defaultBindings()` and
`normalizeSequence()`.

**Constraints on any new default.**

- **Do not test reachability with synthetic input.** `QTest::keyClick()` does
  not reproduce a keyboard layout: it reported `Ctrl++` as dead when it is
  exactly what the `+` key emits on the user's Italian layout. Verify against
  the real keyboard, as `CLAUDE.md` records.
- Every binding is overridable in `[keys]`, so this is about what a fresh
  install feels like, not about what is possible.
- `Return` is a special case already resolved: it belongs to `open_thread` but
  the query bar claims it back while focused, so a proposal that moves it must
  not resurrect that bug.

## 40. No live filter over the current view

**Observed (user, 2026-08-05):** "search in current view", spelled out as two
things: "a light filter applied live on the current view", and "a search bar
appearing as soon as we type while no entry box is focused".

**Cause (verified in code):** the only search is the query bar, which runs a
notmuch query and replaces the result set. There is no client-side filtering
of an existing result: no `QSortFilterProxyModel` anywhere in `src/`, and
`ThreadListModel` has no filter of its own. Narrowing the current view therefore
means writing a new notmuch query and losing the view.

**Approach.** Distinct from the query bar, and the distinction is the point: this
filters rows already fetched, without touching notmuch.

- A filter over the model's loaded rows, matching subject and from, case
  insensitively. No worker round trip.
- A filter strip that appears on the first keystroke while no entry box has
  focus, and disappears on Escape, restoring the full result set.

**Constraints.**

- **Type-to-filter competes with the plain-letter shortcuts.** Item 3's outcome
  records that a plain-letter `QAction` shortcut is suppressed only while an
  editable widget has focus, which is exactly the state this feature does not
  start in. Any binding that is a bare letter would be swallowed by the filter
  strip or would swallow it. Check the current defaults before choosing the
  trigger, and prefer appearing only for characters no action claims.
- Escape already blanks the message pane (item 32). If Escape also closes the
  filter, decide the precedence explicitly rather than letting whichever handler
  runs first win.
- The filter is presentation only: it must not clear the selection, the undo
  stack, or the query, and the pending-edit count must not move.
- Interaction with item 39: a filter and a sort over the same rows want the same
  proxy. Whichever is built first should leave room for the other.

## 65. No full code review and optimization pass

**Observed (user, from the notes):** "full code review and optimization."

**Cause:** not a defect. The codebase has grown from the 0.1.0 spec through
sixty-odd backlog items, and nothing has gone back over it as a whole.

**Why this cannot be planned from the backlog.** "Review and optimize" names no
symptom, no measurement and no target. There is no reported slowness to chase,
and the one performance property the design does commit to (threads emitted in
batches of 200 so a 10k-thread query paints immediately) already holds. An
optimization pass with no measurement behind it is the kind of work that
produces a large diff and no change a user can notice.

**What it needs before it can be sized.** The user saying which of these they
meant: a correctness/security review of a named area, a specific operation that
feels slow with the query that makes it slow, a dead-code and duplication sweep,
or the translatability audit that is already item 22. The first three are
different pieces of work with different sizes, and the fourth is already
recorded.

**Size: `?`, unspecified.** Do not propose a design for this; ask.

## 68. A forwarded subject gets no `passed` tag

**Observed (user, from the notes):** "passed tag should appear when subject is
`Fwd:` and `Fw:`." Refined in session on 2026-08-11: the user had noticed
`passed` appearing on messages whose subject carried `Fwd:` and not on `Fw:`,
and asked to expand the rule to both.

**Cause:** there is no rule to expand. `passed` is the Maildir `P` flag in the
message filename, translated into a tag by notmuch because
`maildir.synchronize_flags=true`. The flag is written by whichever client
forwarded the message, or by the server over IMAP; nothing reads a subject line
anywhere in the chain. qtmaildir only ever colours the tag
(`src/tagcolors.cpp:36-37`) and the database's `post-new` hook does not mention
it either.

**Measured against the real database (2026-08-11):**

| Query | Count |
|---|---|
| `tag:passed` | 6 |
| `tag:passed and subject:"Fwd:"` | 1 |
| `tag:passed and subject:"Fw:"` | 0 |
| `subject:"Fwd:" and not tag:passed` | 194 |
| `subject:"Fw:" and not tag:passed` | 28 |

Six tagged messages in the whole database, and every one of them carries `P` in
its filename flags. The single overlap with `Fwd:` is a message that was
forwarded and whose subject was already a forward, not evidence of a rule: 194
`Fwd:` subjects carry no tag at all. The correlation the observation rests on
does not exist.

**Approach and the decision it needs first.** Two different features, and the
measurements above decide how far apart they are.

*Display only.* The card shows a forwarded mark when the subject matches. Touches
no mail, changes no flag, reversible by deleting the rule. XS.

*Write the tag.* qtmaildir sets `P` from a subject heuristic. With
`maildir.synchronize_flags=true` that flag is a filename change that mbsync
carries out to the server, on 222 existing messages, on a guess about a string.
Not cleanly undoable, and it asserts a meaning for a flag this application did
not define. Recommended against; recorded so the choice is deliberate rather than
forgotten.

**Constraints:** localised clients use their own prefixes, and `Fwd:` can appear
inside a subject rather than at its head, so whatever matches must be anchored.
If the tag is ever written, it must not be re-applied on every sync in a way that
produces pending edits the user never made, item 28 is the record of a count
going wrong. The display-only route avoids that entirely, since it derives the
mark at paint time and stores nothing.

**Size: S** as written, XS if it is display only. Most of it is the decision, not
the code.

**Status:** left open deliberately on 2026-08-11. The cause is settled and the
options are costed; the user has not chosen, and no code was written.

## 72. No khard/khal integration

**Observed (user, from the notes):** "investigate khard/khal integration (light
PIM, probably worthy after we add send capabilities)."

**Cause:** not a defect. v1 is read-and-organize; there is no address book and no
calendar anywhere in the codebase.

**Why this cannot be planned.** The user's own note places it after send, and
send is v2. What "integration" means is undecided: completing recipients from
khard when composing, showing a sender's card, or acting on an invitation.
Those are three different features.

**Size: `?`, unspecified**, and out of scope until v2 exists. Ask before designing
anything.

## 94. `pinned` has nothing left to decide once the buttons are built-in

**Observed (user, 2026-08-15),** thinking past item 93 rather than from the
notes:

> after we've migrated [...] we can drop my 4 redundant (by then) saved queries,
> and there won't be a need for pinning anymore. The buttons will be driven by
> the hardcoded queries, the menu will be the home for saved queries.

**The end state this describes:** the query row is built-in filters ONLY, and
every saved query lives in the menu. No mixing, so nothing has to decide which
saved queries get button real estate, and `SavedQuery::pinned` is dead weight.

**This also disposes of a problem item 93 would otherwise have to solve.** With
both tiers sharing one row, something must order the four filters against the
user's pinned queries. Under this end state the question does not arise.

**Blocked on 93, and deliberately not part of it.** The user needs to live with
the four buttons first and confirm they cover what they actually use. If one is
wrong, pinning is the escape hatch, and it has to still be there to be used.
Closing 93 and this together would remove the fallback before it was needed.

**This is a user-visible removal, not a cleanup.** `pinned` shipped in 0.18.0:
`SaveQueryDialog` offers "Show as a button" (`src/savequerydialog.cpp:104`) and
the right-click menu offers "Move to menu" / "Show as a button"
(`src/mainwindow.cpp:1797`). Anyone who put a saved query on the row loses that
permanently. Semver on the user-visible surface makes it a minor bump with an
`### Upgrading` note.

**The stored field is a separate decision from the UI.** `pinned` is written to
queries.json (`src/config.cpp:603`) and read back (`:542`). Two options, and the
cheaper one is also the reversible one:

- **Stop reading it, leave it in the file.** Harmless: an ignored key, preserved
  by the unknown-field handling, and a build that reintroduces pinning would
  find every user's setting intact.
- **Strip it on the next save.** Cleaner file, and irreversible for anyone who
  had it set.

Prefer leaving it unless the user asks otherwise. No `kQueriesFormatVersion`
bump either way: an ignored optional field is not a breaking change.

**Size: S.** Removing a field, two UI affordances and their tests.


## 99. The unread action is labelled "Toggle unread" whichever way it will go

**Observed (user, from the notes):** "the label for 'toggle unread' should be
dynamic: on an 'unread' message it should be 'Mark as read', on a 'read'
message it should be 'Mark as unread'."

**Cause (verified in the code).** `src/mainwindow.cpp:867` registers one static
label, `tr("Toggle &unread")`, and the lambda decides the direction at
invocation time from the current row. The action carries that text in three
places at once: the Message menu (`:1060`), the thread context menu (`:1167`)
and the toolbar (`:1122`, with the `mail-mark-unread` icon). Nothing updates it
when the selection changes.

**Not as simple as reading the current row**, which is why this is S and not XS.

- The action applies to the WHOLE selection and picks one direction from the
  current row, so with a mixed selection any label naming a single outcome is
  either wrong for some rows or has to describe the rule ("Mark all as read").
- A menu action's text is read when the menu opens, but a TOOLBAR button's text
  is on screen continuously, so it has to track `selectionChanged` rather than
  being computed at popup time. `currentRowChanged` is the wrong signal for
  anything selection-shaped, per `CLAUDE.md`.
- The accelerator is inside the word (`Toggle &unread`). Two different labels
  need two accelerators chosen so neither collides in the Message menu, which
  already holds "Mark &spam" and "&Important".
- The shortcut list (Help > Keyboard shortcuts) and the config's `[keys]`
  section both name the action `toggle_unread`. The action NAME must not change
  with the label, or every user's config breaks. Same rule as item 57, which
  changed "Flag" to "Important" on screen and left the action and tag alone.

**Approach.** Compute the label from the same state the lambda already uses,
which since item 105 is `MainWindow::everySelectedRowHasTag("unread")`, update
it on `selectionChanged`, and keep a neutral fallback for an empty or mixed
selection. Decide with item 98, which raises the identical question for
"Important".

**Use that helper rather than re-deriving the state**, or the label and the
action can disagree. It already encodes the two things this gets wrong on its
own: a reply answers about its MESSAGE, not its thread, and the answer is over
the whole selection rather than the current row.

**Constraints.** Every label is user-facing and needs `tr()`. Since the strings
are chosen at runtime rather than written once, all of them must exist as
literals `lupdate` can see; a string built by concatenation is not translatable.
`ctest -R translations` is the check.

**Size: S.** Mostly the mixed-selection and toolbar decisions, not the code.

## 101. Sync is account-aware for edits but not for the account the user is looking at

**Observed (user, from the notes):** "sync button should be account-aware."

**Cause (verified in the code).** `MainWindow::pendingSyncChannels()`
(`src/mainwindow.cpp:3550`) resolves channels from `m_editedAccounts`, the set of
accounts the user has made EDITS in, and from nothing else. The account dropdown
is not consulted. With nothing pending it returns empty on purpose, and
`mailsync.sh` turns that into `mbsync -a`, every channel.

**Item 49 built exactly this and the reasoning still holds.** The comment states
it: with nothing pending the run is a FETCH, and narrowing a fetch to wherever
the last edit happened would "quietly stop collecting mail everywhere else".
Fetching is global by nature; carrying edits is not.

**So this needs a decision, not a fix.** The note does not say which of two
things the user means, and they are different features:

*Sync only the selected account, on demand.* A deliberate "sync this account"
that ignores the pending set, presumably beside the existing Sync rather than
replacing it. Useful when one account is slow and the user wants their mail from
another one now. The risk is the one item 49 named: a button that looks like
Sync and quietly does not collect the rest of the mail.

*Show which accounts a sync will cover.* No behaviour change at all, just making
the existing account-awareness visible, since today the user cannot tell whether
a run is narrowed or full. The status bar already names each channel as mbsync
reaches it (item 42), so most of this exists.

**Constraints.**

- The account dropdown is a VIEW filter. Making it also steer sync couples two
  things the user may reasonably want apart: looking at one account while
  fetching all of them is the normal case, not an edge case.
- Whatever narrows a run must still carry every pending edit, or an edit is
  stranded with nothing on screen to say so. `pendingSyncChannels()` already
  falls back to a full sync when it cannot resolve a channel for an edited
  account, and that safety must survive.
- An account with no `[account.<key>]` section, or one whose section names no
  channel, has no channel to sync. The fallback covers it today.

**Size: S** for the on-demand button, XS for the visibility half. Ask which.

## 104. Mail visible in Thunderbird never reaches qtmaildir

**Observed (user, from the notes):** "sync doesn't work compared to thunderbird.
New mail received on thunderbird did not appear in qtmaildir. Need to investigate
further."

**Cause: NOT established.** Recorded because it is a defect report about mail
going missing, which is the most serious kind this backlog carries, and it has
been sitting in the notes unrecorded. What follows is one measured mechanism that
would produce exactly this symptom, not a diagnosis.

**qtmaildir cannot show what mbsync did not fetch, and mbsync fetches folders by
pattern.** Three of the five channels in the user's `~/.mbsyncrc` name their
folders explicitly:

```
Patterns "INBOX" "[Gmail]/Posta inviata" "[Gmail]/Bozze" "[Gmail]/Speciali"
```

and one names only `"INBOX"`. The two non-Gmail channels use `Patterns *`.
Gmail applies labels, and a message whose label is not one of those four is in a
folder mbsync never asks for. Thunderbird speaks IMAP directly and sees every
folder, so the same message is visible there and absent locally. This is a
configuration property of the user's mbsyncrc, outside this repository entirely.

**One inconsistency worth reporting regardless**, found while checking the
above: one of the Gmail accounts is configured in `qtmaildir.conf` with
`sent = [Gmail]/Posta inviata` and `drafts = [Gmail]/Bozze`, while its mbsync
channel has `Patterns "INBOX"` and fetches neither. The Sent and Drafts filters
for that account can therefore only ever be empty. That is real, and it is
independent of whatever this item turns out to be.

**Approach.** Reproduce before anything else, and the reproduction has to
distinguish three layers, because the fix lives in a different place for each:

1. Is the message on disk? `find` in the Maildir, or `notmuch count` on a term
   from it. If not, this is mbsync or `.mbsyncrc`, and there is nothing to
   change here.
2. If it is on disk, is it indexed? `notmuch new` and count again. If not, this
   is notmuch config, `new.ignore` or the hook.
3. Only if it is indexed and still not shown is this qtmaildir's defect, and
   then the question is which query hid it: the account scope, the built-in
   filter, or a rule that tagged it out of the inbox.

**Constraints.**

- Ask the user for one concrete example before investigating: which account,
  roughly when, and what Thunderbird shows for it. A general "sync doesn't work"
  cannot be reproduced, and the last four defects in this backlog were all found
  from a specific message.
- The `post-new` hook from mailctl tags mail unattended. A rule that removes
  `inbox` would make a correctly fetched, correctly indexed message vanish from
  the default view, which looks identical to a sync failure from the outside.
  `notmuch search` without a filter is what tells them apart.
- Do not change `.mbsyncrc` as part of this. It is the user's, it is outside the
  repo, and a Patterns change refetches folders.

**Size: `?`** until reproduced. Most likely not a code change here at all.


## 112. Toggle unread on a whole thread cannot reach "all unread" on a partly-read thread

**Observed (user, 2026-08-17):** clicking a thread root and asking to mark the
whole thread unread does not do it. On a seven-message thread with two unread
replies, the result is that every message is toggled unread **except those
two**, which are left as they were. The user asks for an explicit "mark whole
thread read/unread" rather than a toggle.

**Cause (verified in code):** the action exists, and its direction is the
defect. `toggle_unread_thread` (`src/mainwindow.cpp:931`, `Ctrl+Alt+U`) chooses
between adding and removing by asking
`everySelectedRowHasTag("unread", TagScope::Thread)`, which reads
`ThreadListModel::threadFor(index).tags`. That is notmuch's **union over the
thread** (`CLAUDE.md`, item 110), so a thread containing even one unread message
answers "unread" and the action picks *Mark thread read*. There is no input a
user can give that reaches *Mark thread unread* on a mixed thread: the only
threads that take that branch are the ones already entirely read, and the only
threads reporting "not unread" are the ones the user does not need the action
for.

The write itself is absolute and correct. `tagSelected` with `TagScope::Thread`
adds or removes `unread` across every message, so the two unread replies in the
report are not skipped by the write. They are the reason the write ran in the
opposite direction from the one the user wanted.

**A union is not a state, and a toggle needs a state.** This is the same class
as item 110 and the third time the union has produced a defect. Items 105 and 88
fixed *which object* a toggle resolved; this one is about a thread having no
single answer to give. `everySelectedRowHasTag` is a two-valued predicate over a
three-valued reality: all read, all unread, or mixed. The mixed case is the one
that has no correct toggle direction, and picking either one silently is what
ships as "the action does the wrong thing".

**Approach.** The user has already named it: stop toggling at thread scope.

- Split `toggle_unread_thread` into two explicit actions, **Mark thread read**
  and **Mark thread unread**, each with a fixed direction. Both appear in the
  "Whole thread" submenu, where an entry always carries text, so a fixed label
  is honest in a way a toggle's cannot be.
- The message-scoped `toggle_unread` stays a toggle. One message has a real
  two-valued state, so the trap does not exist there. Do not "unify" the two:
  the asymmetry is the point.

**Constraints.**

- **Adding an action is four places**, all enforced by tests that fail
  confusingly: `KeyMap::knownActions()`, `defaultBindings()`, the icon table,
  and the no-duplicate-icons exception list. See `CLAUDE.md`. Splitting one
  action into two means one new entry in each, and the pair shares the twin's
  icon under the existing named exemption for thread actions.
- **`Ctrl+Alt+U` is taken by the action being split**, and the whole-thread
  bindings are already one modifier out from their twins because `Ctrl+Shift+U`
  was claimed. Two directions need two sequences; if a second chord cannot be
  found that is not worse than the menu, bind one and leave the other to the
  submenu rather than inventing a three-modifier chord nobody will press.
- **This interacts with items 98 and 99**, which is the reason to decide all
  three together. 99 asks for a dynamic label on the message-scoped toggle,
  which is the opposite move: keep the toggle, make the label tell the truth.
  A thread cannot do that, because on a mixed thread there is no true label to
  show. Deciding 99 first will produce the wrong answer here by analogy.
- The undo entry must name the direction that ran (`Mark thread unread`), not
  the action. `tagSelected` already takes the text, so this comes free from
  splitting.
- **The test needs a MIXED thread**, which is the whole defect: a thread whose
  messages are all in one state answers identically whichever way the direction
  is computed, so a fixture built from a uniformly-unread thread passes against
  the bug. Same trap as item 88's opposite-states requirement, recorded in
  `CLAUDE.md`.

**Size: S.** The write path is already correct and thread-scoped; the work is
the action split, the four registration sites, the binding decision, and a test
over a mixed thread.


## 113. No way to see a message's HTML source

**Observed (user, 2026-08-17):** reviewing item 100's removals, "view source
could be useful, we might have to implement it."

**This item exists because item 100 removed something it was not asked to.**
The user named Back, Forward, Reload and Save page. `ViewSource` was added to
that list by the agent, on the reasoning that it was "the same kind of thing",
and it is not: the other four have nothing to act on, while view-source has a
real document and a real use, checking what a message actually contains. The
removal is recorded here rather than quietly reverted, because the reasoning
that produced it is the part worth not repeating.

**Cause (verified in code):** restoring Chromium's entry would not work anyway,
which is why this is an implementation item rather than a one-line revert.
`QWebEnginePage::ViewSource` navigates to `view-source:<url>`. The pane's
document is a `data:` URL (`requestinterceptor.cpp:90-105` records that
`setHtml()` navigates to data: and applies the base URL afterwards), and
`MessagePage::acceptNavigationRequest` accepts only a typed main-frame
navigation, so the attempt is refused before the interceptor even sees it.
Restoring the entry would produce a live-looking menu item that does nothing,
which is the same defect item 100 was reported for.

**Approach.** Our own action, not Chromium's: a dialog showing the message's
HTML as plain text. The source is already in hand, since `HtmlBuilder` produced
it and `MimeParser` holds the original part; nothing needs fetching.

**Constraints.**

- **Plain text is a SECURITY property here, not a style.** `CLAUDE.md` states
  it for `MessageDetailsDialog`, and it applies with more force to this: the
  content is a stranger's markup, and the whole point of the dialog is to show
  it uninterpreted. Set `Qt::PlainText` explicitly on whatever displays it; a
  `QLabel` guesses under `Qt::AutoText`. A `QPlainTextEdit` cannot render
  markup at all and is the obvious choice.
- Decide which source is shown: the message's ORIGINAL HTML part, or the
  document `HtmlBuilder` generated around it. They are different, and the
  useful one is almost certainly the original, since the wrapper is ours and
  known. Say which in the dialog rather than leaving the user to guess.
- A message with no HTML part needs an answer that is not an empty window.
  `messageview.cpp:933` already has the string for this case.
- Reachable from the body context menu, where the removed entry was, so the
  gesture the user reached for keeps working.

**Size: S.**

## 114. Save image is offered on every image and does nothing

**Observed (user, 2026-08-17):** right-clicking an image in the message pane
offers "save image", among other entries item 100 never saw because the test
built a menu by hand and no real image was ever clicked.

**Cause (verified in code):** there is no download handling anywhere in the
tree. `grep -rn "downloadRequested\|DownloadRequest" src/` returns nothing, so
Chromium emits the request and no handler answers it. The entry is present,
looks live, and silently does nothing, which is the same class of defect as
item 100 itself.

**Approach, and the security question it raised was resolved by the user.**
The first proposal was to scope this to `cid:` parts and refuse remote images,
on the grounds that saving a remote image means a fetch triggered from a
message. **The user pointed out that this is wrong**, and it is: once remote
content has been granted and loaded, the bytes are already fetched and cached.
Saving them is a local copy, not a new request, and blocking it adds no
security while making the entry useless. The reasoning applied to *fetching*,
which has already happened by the time the entry is reachable.

The real constraint is the neighbouring one: **the save must not itself cause a
fetch.** An image that was never loaded, because it is remote and not granted,
has no bytes to save, and the entry should be unavailable rather than reaching
for the network to satisfy it.

- Connect `QWebEngineProfile::downloadRequested` and let Chromium write the
  file, with the directory chosen through `QFileDialog` as the attachment save
  already does.
- The rejected alternative: fetching the bytes ourselves to reuse
  `Attachment::saveTo()`. That is a second network request originating from a
  message, which is exactly what the interceptor exists to prevent, and it
  would bypass the per-render remote grant. `cid:` images would map onto that
  path cleanly and remote ones cannot, which is why the uniform route wins.

**Constraints.**

- **The path checks are not optional and are already written.** `CLAUDE.md`'s
  web-view notes: reduce to basename, strip separators, resolve against the
  chosen directory, refuse anything escaping it, and compare resolved paths as
  paths rather than with `startsWith`. A filename suggested by a download
  request is untrusted input in exactly the way an attachment filename is.
- Do not let this become a second general download route. It saves an image the
  user right-clicked, nothing else; `SavePage` stays removed.
- No overwriting. `saveWithoutOverwriting` exists because a silent overwrite
  lost six of sixteen files while reporting every one as saved.
- Report the outcome through `statusMessage`, as every other save does. A save
  with no feedback is the failure item 13 was about.

**Size: S.**

## 118. No way to empty the trash from inside the app

**Observed (user, 2026-08-17):** raised while reviewing item 103's spec, as
something that had been forgotten rather than newly noticed: "we could add
'Empty Trash' to the backlog as a future item. I forgot it existed, but I don't
want to squeeze it in this spec."

**Blocked on 103**, which creates the trash folder this would empty. Until that
ships there is nothing to empty: Delete writes a tag and moves no file, so no
account has a populated trash folder except through another client.

**Deliberately excluded from 103's spec**, at the user's request and recorded in
its "Out of scope" section. Worth keeping separate for a reason beyond scope
control: emptying the trash is the first action in this application that would
destroy mail with no undo. Every mutation so far is a tag or, after 103, a move,
and both are reversible. A purge is not.

**Approach, unspecified.** The shape depends on decisions not yet made, and the
spec for 103 answers none of them:

- **Local or remote.** Deleting the files locally and letting `Expunge Both`
  carry it to the server is one thing; asking the provider to empty its own
  trash is another, and mbsync offers no verb for the latter. The first is
  probably what "Empty Trash" should mean here.
- **Whether the no-confirmation rule survives it.** It does not, on the face of
  it. `CLAUDE.md` grants undo in place of confirmation dialogs, and this is the
  action where undo cannot exist. That makes it the second item, after 103, that
  re-examines the rule rather than assuming it, and unlike 103 it will probably
  have to break it.
- **Per-account or all-accounts**, which should follow whatever the Trash filter
  does once 103 ships rather than being decided independently.

**Size: S**, provisionally, and not worth sizing properly until 103 exists.

## 119. The unsynced-changes count cannot be opened to see what it counts

**Observed (user, from the notes):** "the bottom left statusbar message needs to
be clickable and show what 'N unsynced changes' are in a modal window".

**Cause (verified in the code).** `m_pendingLabel` is a plain `QLabel` added to
the status bar with `addPermanentWidget` (`src/mainwindow.cpp:502-505`). A
`QLabel` has no clicked signal and none is installed, so there is nothing to
click and no route to a list. It carries a tooltip and nothing else.

**The count is a SUM OVER FOUR SOURCES, and that is what makes this bigger than
it looks.** `pendingEditCount()` returns
`m_pendingTagEdits.size() + m_unnettablePendingEdits + held + heldMoves`.
Three of those can name what they hold: `m_pendingTagEdits` is a
`QHash<QString, bool>` keyed by message id, `m_heldEdits` and `m_heldMoves` are
queues of edits waiting for a sync to end. **`m_unnettablePendingEdits` is a
bare `int`** (`src/mainwindow.h:1248`), deliberately so: it counts confirmed
changes that carry no message ids and therefore cannot be netted against
anything.

So a dialog built from what is currently kept would list three of the four
groups and then have to account for a remainder it cannot describe. Showing "and
3 more" is worse than the tooltip, because the user opened the window
specifically to find out what those were.

**Approach.** Two halves, and the second is the real work.

- The clickable half is small: a label that emits on click (an event filter, or
  a flat `QToolButton` styled as a label), plus a dialog listing what the three
  describable groups hold. The message pane already resolves an id to a subject.
- The complete half needs `m_unnettablePendingEdits` to become something that
  can name its entries. Its comment says why it is an int: understating the
  indicator is the direction that costs the user work, so it counts what it
  cannot identify rather than dropping it. Making it describable means finding
  out what those changes actually are and whether they can carry an id.

**Constraints.**

- **The count is deliberately conservative and must stay so.** Item 28 and item
  54 both landed on this indicator being wrong in the direction that made the
  user think their work was safe. A dialog that lists fewer changes than the
  count claims is the same failure in a new place: reconcile the two, or state
  the remainder honestly rather than hiding it.
- **An external `notmuch` run can clear pending changes without this count
  noticing**, which the tooltip already admits. A dialog makes that staleness
  much more visible, since a listed change may no longer exist. Worth deciding
  whether the dialog re-verifies against the database before showing.
- Read-only. This is an information window, not a place to retry or discard a
  change; either would be a new mutation path with its own undo question.

**Size: S** for the clickable half over the three describable groups. **Unknown**
for the fourth, and the item is not complete without it.

| # | Item | Why here |
|---|------|----------|
| 12 | `HtmlBuilder` CSS is light-theme only | **Done 2026-08-07**, and moved to the main status table. Kept listed here so the split from item 5 stays traceable. |
| 120 | No way to tell a tag applied by a rule from one applied by hand | **Postponed by the user**, and recorded here on 2026-08-19 from their notes ("should the UI allow to discriminate when a message has been tagged by a rule?"). Not plannable as it stands: nothing records the provenance. A rule has an `id` in `~/.config/mailrules/rules.json`, but `mailrules.py` writes only the tags the rule names and keeps no note of which rule wrote them, so the information does not exist to display. Answering it means the HOOK storing something per message, which is a shared-format change across both repos and needs the procedure in `CLAUDE.md`. Ask the user what they would do with the answer before designing that. |

## Adding to this document

Append a row to the status table with the next free number, then a section using
the same shape: **Observed** (what the user saw), **Cause** (the code, with file
and line, verified not assumed), **Approach**, **Constraints**, and
**Verification** where it is not obvious. Do not renumber. Do not delete: mark
`dropped` with a reason.

**When an item closes, move its section to
`2026-08-03-post-0.1.0-usability-closed.md`** and leave the status table row
here with its date and outcome. This is what keeps the file readable, and it is
the step that was missing for seventy items: doing it only once, as item 73 did,
buys a few months and then the problem returns. Move the section on the commit
that closes the item, not in a later cleanup pass. Where the closed section
records a trap that is still true of the code, that trap belongs in `CLAUDE.md`,
which is where it will actually be read.

**A fully specified item goes in its own file under `docs/superpowers/specs/`,
not inline here.** This document is a backlog: its job is to say what is open,
how big it is, and what decides whether it can be picked up. A design that runs
to a hundred lines buries that under itself.

The split is by depth, not by size on the day. An entry stays here while it
records an observation, a cause and an approach. It moves out once it carries
decisions the user made, measured evidence, and constraints that have to be read
before writing code. Items 53 and 63 are the pattern: the entry keeps the
finding and the size, and points at the spec with one line saying to read that
instead. Carry the two or three constraints a reader needs in order to decide
whether to open the spec at all, and leave the rest there.

Name the spec `<date>-<name>-design.md`, and state in its header which backlog
items it resolves, so the numbering stays traceable in both directions.
