+**There is no built-in default set.** Nothing in the code distinguishes a
+default query from a user-made one: every entry in `[queries]` is user-written
+config and is rendered identically. Sent is the lone exception and is not in
+`[queries]` at all, it is built from `allSentQuery()`
+(`src/mainwindow.cpp:579`). So the two tiers need a mechanism that does not
+exist yet.
+
+**Decision (user, 2026-08-13): saved queries move out of the INI into
+`~/.config/qtmaildir/queries.json`.** The user proposed it by analogy with the
+rules file, and it is a better answer than the two the entry had considered (a
+per-query `pinned` flag inside `[queries]`, or a `[general] pinned_queries`
+list). It solves three things at once where those solved one each.
+
+- **Order.** `[queries]` is read through `childKeys()`, which returns keys
+  alphabetically and not in file order, so button order is alphabetical today
+  and cannot be chosen. `src/config.cpp:401` already records that a hand-rolled
+  parser would be needed to change it. A JSON array is ordered intrinsically,
+  so the row of buttons can be arranged.
+- **The `pinned` flag**, which decides the two tiers.
+- **Per-query account scope**, which the save dialog wants and which
+  `SavedQuery` (`src/config.h:99`) has no room for: it is `{name, query}` and
+  nothing else.
+
+**Take the shape of `rules.json`, not its machinery.** That file is JSON because
+it has TWO independent implementations that must agree, this repo and mailctl's
+`mailrules.py`; the unknown-field preservation and the `kFormatVersion`
+handshake exist to stop two programs destroying each other's writes. Queries
+have exactly one reader, so copying that wholesale would import the ceremony
+without the reason for it. What is worth carrying across is a versioned document
+read and written by one class, preserving unknown fields on the way through so a
+field added later is not stripped by an older build.
+
+**Migration: read `[queries]` once, write the JSON, and leave the INI section
+alone.** `[queries]` exists in the user's live config and in the README, so it
+cannot simply stop being read. On a run where `queries.json` is absent, the
+section is read, converted and written out; from then on `[queries]` is ignored
+entirely. **Do not strip the section:** removing it means rewriting the
+hand-edited file with QSettings, which drops comments and key order across the
+WHOLE file and is exactly the loss this decision avoids. Leaving it costs a few
+stale lines the user can delete by hand, and keeps a downgrade working. The
+README should mark it legacy. Reject the third option, reading both forever:
+two sources of truth for one thing, with no answer for which wins on a name
+collision or where the dialog writes.
+
+**This retires the entry's original open question.** It asked whether the write
+went to `qtmaildir.conf` or `uistate.conf`, and both answers were poor: the
+first machine-writes a hand-edited file, the second files user intent as window
+state. A machine-written JSON document beside the hand-written INI is the
+cleaner split, and the README caveat about losing comments goes away with it.
+The file belongs in `~/.config/`, not `~/.local/state/`: it is the user's
+intent, hand-editable, and belongs in a config backup, which a state directory
+is commonly excluded from.

 never has been, whatever an older revision of this entry said. Moving the
 buttons to their own row is a change to that layout code.
 
+**Constraint: `startup_query` names a saved query by name**, and resolves
+against the list with a case-insensitive match plus a fallback to the first
+entry (`Config::startupSavedQuery()`, `src/config.cpp:422`). It must keep
+resolving across the migration, which also means the "first entry" fallback
+stops meaning "alphabetically first" and starts meaning "first in the user's own
+order". That is an improvement rather than a regression, but it changes which
+query a config with an unmatched `startup_query` opens on, so it is a
+user-visible change and belongs in the changelog.
+
+**Constraint: the README documents `[queries]` in three places** (the

+description at :256), including a line explaining that buttons appear in
+alphabetical order rather than file order. That explanation is exactly what this
