Make Settings sidebar content scrollable

Records how to add a setting -- one schema entry -- and the failure
modes found building the pages. Every one of them fails silently rather
than loudly, which is why they are worth writing down: a wrong readAs
makes successful writes look rejected, hyprpaper accepts an all-outputs
wallpaper request and ignores it, and a copy of the Quickshell config
shares the live shell's ID so an "isolated" harness can kill the running
desktop.

Also documents the two generated configurations and why they are
generated: ~/.config/hypr is a symlink into this repository, so writing
there at runtime would commit machine state to a tracked file.

+## Generated configuration
+
+Two ecosystem tools cannot read the shared settings file, and their configs live
+in this directory — which is a symlink into the Panama repository, so writing to
+them at runtime would put machine state into a tracked file. Both are therefore
+generated elsewhere:
+
+| Tool | Generated to | Pointed there by |
+|---|---|---|
+| `hypridle` | `$XDG_STATE_HOME/panama/hypridle.conf` | a systemd user drop-in installed by `panama-idle install` |
+| `hyprpaper` | not generated — the wallpaper is applied over IPC and re-applied at shell start | — |
+
+`quickshell/scripts/panama-idle` regenerates the hypridle config from the
+settings store and restarts the daemon. `hypridle.conf` in this directory
+remains the shipped default and is what runs when the drop-in is not installed;
+Panama Settings shows which of the two states you are in rather than presenting
+controls that quietly do nothing.
+
+Remove the drop-in and go back to the shipped config with:
+
+```sh
+~/.config/quickshell/scripts/panama-idle remove

 `tests/hypr/prefs-fallback-contract.sh` pins that, including that Hyprland still
 accepts the config in each of those states.
 
+### Adding a keybind: use `bind`, not `hl.bind`
+
+Every bind in `keybinds.lua` goes through a local `bind()` wrapper that
+substitutes the chord from a stored override, so shortcuts can be moved from
+Panama Settings without editing this file.
+
+```lua
+bind(mod .. " + Q", hl.dsp.window.close(), { description = "Close window" })
+```
+
+Only the **chord** is ever taken from settings — the action is always the Lua
+value written here. A stored override can therefore move a shortcut but can
+never make one do something else, which is what makes reading overrides from a
+file the user can edit safe.
+
+Overrides are keyed by the **shipped chord**, not the description. Descriptions
+are not unique: "Calculator" is both `SUPER + C` and the `XF86Calculator`
+hardware key, and keying by description moved both onto the same new chord,
+silently costing the hardware key.
+
+An override whose value is not a plausible chord is ignored in favour of the
+shipped one, so a hand-edited `settings.json` cannot cost you a keymap.
+
 ### Keybind descriptions are required
 
 Every `hl.bind` must pass a `description`. Hyprland reports Lua-defined binds

+# Panama Settings
+
+The control centre for everything Panama owns. Anything the system owns —
+hardware, accounts, printers — is delegated to GNOME Settings and labelled as
+such rather than half-reimplemented.
+
+## Adding a setting
+
+One schema entry. That is the whole job.
+
+```qml
+// config/PreferenceSchema.qml
+{
+    key: "blurSize", type: "int", def: 8, min: 1, max: 20, step: 1,
+    unit: "px", group: "effects",
+    label: "Blur radius",
+    detail: "Larger is softer and costs more frame time",
+    hypr: { path: ["decoration", "blur", "size"], option: "decoration:blur:size", readAs: "int" }
+}
+```
+
+```qml
+// the page
+SliderRow { setting: "blurSize" }
+```
+
+Persistence, validation, clamping, reset, search indexing, and — with a `hypr`
+block — live application to the compositor and the startup replay all derive
+from that entry. There is nothing else to register.
+
+If it is compositor-backed, add the matching `prefs.get("blurSize", 8)` in
+`hypr/looks.lua` so the Hyprland config still stands alone with no settings
+file.
+
+## The rows
+
+| Component | For |
+|---|---|
+| `SettingsPage` | The page scaffold: title, lede, optional pinned `header` |
+| `ToggleRow { setting }` | A boolean |
+| `SliderRow { setting }` | A number; `zeroLabel` renders 0 as "Never"/"Instant"/"None" |
+| `ChoiceRow { setting }` | An enum, as a segmented control |
+| `ActionRow` | A button: opens a GNOME panel, runs a one-shot |
+| `TextRow` | A genuinely read-only fact |
+
+`TextRow` is for facts, not for settings that were merely expensive to wire.
+Before Stage 3 more than half of all rows were static text standing in for
+controls; that is the failure this vocabulary exists to prevent.
+
+Rows write through `SystemSettings.commitPreference(key, value)`, which routes
+compositor-backed keys through apply-and-verify and local keys straight to the
+store. A row never needs to know which kind it holds.
+
+## Things that will bite you
+
+**`readAs` describes the answer, not the setting.** `hyprctl getoption` returns
+the value in a different JSON field per type — `int`, `bool`, `float`, `str`,
+and `css` for gaps (a four-value box). Declaring the wrong one does not fail
+loudly: it makes every write to that key look *rejected*, and the user sees an
+error for a change that worked. `tests/quickshell/schema-hypr-shape-contract.sh`
+asks the compositor for the real shape of every mapped option.
+
+**Never trust an exit code from `hyprctl`.** `keyword` refuses to work on a
+Lua-configured Hyprland, prints the refusal to stdout, and exits 0. `eval` exits
+0 on syntax and runtime errors too. The only trustworthy signal that a write
+landed is reading the value back.
+
+**The Settings window is tiled.** `implicitWidth` is a hint; the layout decides,
+and it ranges from a half-screen split to the full display. `SliderRow` stacks
+its control under the label below 520px. Test narrow.
+
+**Binding an anchor to `undefined` does not reliably release it.** Switching
+layouts that way left a slider anchored to both edges with the label squeezed
+into what was left. Position explicitly instead.
+
+**Inside a `SettingsCard`, `parent` is the card's internal Column.** So
+`parent.modelData` in a nested `Repeater` is undefined and the rows silently
+never appear — you get a card with a heading and nothing under it. Address the
+outer model through an explicit `id`.
+
+**A `TapHandler` declared as a child of `SettingRow` lands in the trailing
+slot**, because that is the row's default property, so only the right-hand edge
+becomes clickable. Use `activatable: true` with `onActivated` for a whole-row
+target.
+
+**A copy of the Quickshell config shares the live shell's ID.** Quickshell
+derives the Shell ID from config *content*, not path, so
+`cp -a config/dot/quickshell $tmp && qs -p $tmp kill` kills the running
+desktop, and `qs -p $tmp ipc call …` can drive it. Harnesses that point at a
+single distinct `.qml` file are safe; copying the whole directory is not.
+
+## Where state lives
+
+| File | Holds |
+|---|---|
+| `~/.config/panama/settings.json` | Everything in the schema. Read by the shell *and* by `hypr/prefs.lua` |
+| `$XDG_STATE_HOME/panama/panama-home.json` | Home accessory favourites and aliases |
+| `$XDG_STATE_HOME/panama/backups/` | Settings snapshots |
+| `$XDG_STATE_HOME/panama/hypridle.conf` | Generated idle config |
+
+`SystemSettings.restoreDefaults()` spans all of them. A reset that silently
+skipped one would be worse than having no reset, because nothing would say so.
+
+## Not stored by Panama
+
+Timezone and network time are read from and written to `timedatectl` directly.
+They belong to the machine and are shared with sessions that never see Panama's
+file; storing a copy would create a second answer to a question the system
+already answers.

+
+Not in the original plan. Added after the settings vocabulary made new pages

+scope. Built jointly with the codex agent, which took default applications, the
+page migrations, and the remaining hardcoded values.

+- [x] **Power & Lock** — screen blank, lock, suspend, lock-before-sleep.
+- [x] **Date & Time** — timezone and network time via `timedatectl`.
+- [x] **Accessibility** — pointer size, text scale, motion, contrast.
+- [x] **Search that indexes settings**, not page names.
+- [x] **Editable Dock** — reorder, unpin, add.
+- [x] **Settings snapshots** — save, list, restore.
+- [x] **Rebindable shortcuts.**
+- [ ] Displays: resolution, refresh rate, scale, rotation.
+- [ ] Per-application notification rules.
+- [ ] Window rules (float/tile/workspace) as a page.
+
+**Landed.** Each of these turned up something the compositor or its tools do
+differently than documented, and in every case the failure mode was silence
+rather than an error:
+
+* **hyprpaper 0.8 ignores the "all outputs" form.** `<empty>,<path>` is accepted
+  and does nothing, so a wallpaper set that way appears to succeed and never
+  changes. Its IPC is also much smaller than older versions suggest — `preload`,
+  `listloaded`, `unload`, and `reload` all answer "invalid hyprpaper request".
+* **`cursor:inactive_timeout` is answered as `float`, not `int`.** A wrong
+  `readAs` does not fail loudly; it makes every write to that key look rejected,
+  and the user sees an error for a change that worked.
+* **Snapshot filenames collided at one-second resolution.** A save followed
+  promptly by a restore produced the same name twice, and the restore's own
+  safety snapshot overwrote the file it was about to read. Found by the
+  contract, which restores immediately after saving.
+* **Keying bind overrides by description moved every bind sharing one.**
+  Rebinding `SUPER+C` also dragged `XF86Calculator` onto the same chord.
+  Descriptions are not unique; chords are.
+* **The GNOME delegation allow-list named a panel that does not exist.**
+  `users` is not in `gnome-control-center --list`, so that button opened
+  nothing.
+* **A copy of the Quickshell config shares the live shell's ID.** Quickshell
+  derives it from content rather than path, so an "isolated" harness built by
+  copying the config directory can kill or drive the running desktop. This took
+  the live shell down twice during development. Harnesses pointing at a single
+  distinct `.qml` file are unaffected.
+
+Two configurations are now generated rather than edited, because `~/.config/hypr`
+is a symlink into this repository and writing there at runtime would put machine
+state into a tracked file: hypridle's config, into `XDG_STATE_HOME` with a
+systemd drop-in pointing at it, and the wallpaper, which is applied over IPC and
+re-applied at shell start instead of being written into `hyprpaper.conf`.
+
+The schema gained a `json` type for structured values — the dock's pinned list
+and the keybind overrides — so they live in the one settings file and are
+covered by the one reset, rather than each growing a preference store of its
+own. `restoreDefaults()` spans every store Panama owns, including the Home
+accessory arrangement, which it reaches through that service's existing public
+aliases rather than an API added for the purpose.

+# Panama Settings Completion Codex Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Complete Codex's portion of Panama Settings with default-application and autostart management, shared page scaffolds, and real controls for every remaining hardcoded shell behavior value.
+
+**Architecture:** `DefaultApps.qml` is the typed system boundary for freedesktop default handlers and user autostart entries; `ApplicationsPage.qml` binds reactively to `DesktopEntries.applications.values` and never snapshots the asynchronous model. Existing pages adopt `SettingsPage`; schema-bound values use `ChoiceRow`, `SliderRow`, and `ToggleRow`, while specialized controls and genuinely read-only facts remain specialized or use `TextRow`.
+
+**Tech Stack:** Quickshell 0.3 QML, QtQuick, `xdg-settings`, `xdg-mime`, freedesktop `.desktop` files, Bash/Python contract tests, Hyprland.
+
+**Spec:** `docs/superpowers/specs/2026-08-17-panama-cohesion-design.md`
+
+**Status:** Implemented and independently reviewed on 2026-08-18. The combined
+verification gate is recorded in the integrating commit history.
+
+## Global Constraints
+
+- Claude owns and must be the only editor of `PreferenceSchema.qml`, `SettingsSidebar.qml`, `SettingsShell.qml`, `qmldir`, `ShellState.qml`, `SystemSettings.qml`, `AppearancePage.qml`, `DesktopPage.qml`, `ShortcutsPage.qml`, and `config/dot/hypr/*`.
+- Never use `hyprctl keyword`; every `hl.bind` requires a description.
+- Use `DesktopEntries.applications.values` in reactive bindings. Do not call `byId()` or `heuristicLookup()` in a one-time initialization path.
+- Use `SettingRow.activatable` for whole-row clicks. Nested Repeaters address outer models through explicit ids, never `parent.modelData`.
+- Only these verified GNOME panels may be opened: applications, background, bluetooth, color, display, keyboard, mouse, multitasking, network, notifications, online-accounts, power, printers, privacy, search, sharing, sound, system, universal-access, wacom, wellbeing, wifi, wwan.
+- No mock phase, new visual direction, color literals, or idle animation. Preserve page copy and behavior unless a dead read-only row is replaced by a real control.
+- Automated tests isolate XDG config/state, do not change live defaults or autostart entries, do not launch applications, and do not invoke Home actions.
+
+---
+
+### Task 1: Applications, default handlers, and user autostart
+
+**Files:**
+- Create: `config/dot/quickshell/services/DefaultApps.qml`
+- Create: `config/dot/quickshell/modules/settings/ApplicationsPage.qml`
+- Create only if needed for a safe parser/writer boundary: `config/dot/quickshell/scripts/panama-default-apps`
+- Create: `tests/quickshell/default-apps-contract.sh`
+- Create: `tests/quickshell/applications-settings-contract.sh`
+
+**Interfaces:**
+- Consumes: `DesktopEntries.applications.values`, `SettingsPage`, `SettingsCard`, `SettingRow.activatable`, `ActionRow`, `TextRow`, and Claude-owned routing for page id `applications`.
+- Produces: a singleton `DefaultApps` with reactive `handlers`, `autostartEntries`, `luaAutostartEntries`, `busy`, `lastError`, `refresh()`, `setDefault(role, desktopId)`, and `setAutostart(desktopId, enabled)`.
+
+- [x] **Step 1: Write failing helper/service and page contracts**
+
+Cover seven roles: browser (`xdg-settings default-web-browser`), mail (`x-scheme-handler/mailto`), files (`inode/directory`), terminal (`x-scheme-handler/terminal`), music (`audio/mpeg`), images (`image/png`), and video (`video/mp4`). Use temporary XDG directories and fake `xdg-settings`/`xdg-mime` binaries; assert setters pass separate arguments and reject unknown roles or desktop ids. Fixture user autostart entries must expose id/name/enabled and toggle with standard `Hidden=` semantics; `hl.exec_cmd` entries parsed from `config/dot/hypr/autostart.lua` are read-only and identify their source.
+
+The page contract must require `DesktopEntries.applications.values`, page id/object name, all seven role labels, user and compositor autostart sections, `SettingRow.activatable`, and must reject `Component.onCompleted` snapshots plus `byId()`/`heuristicLookup()`.
+
+- [x] **Step 2: Run focused contracts to verify RED**
+
+```bash
+tests/quickshell/default-apps-contract.sh
+tests/quickshell/applications-settings-contract.sh
+```
+
+Expected: fail because the service/page and behavior do not exist.
+
+- [x] **Step 3: Implement the minimal typed boundary and page**
+
+All process commands use argument arrays. Validate roles against a fixed map and desktop ids against the reactive applications model or a strict freedesktop id pattern plus discovered entries. The page filters role choices from category/generic-name data, sorts by display name, keeps the current handler visible even when category metadata is sparse, and shows calm inline errors. Toggling applies only to files under `$XDG_CONFIG_HOME/autostart`; Lua entries remain read-only with explanatory copy.
+
+- [x] **Step 4: Verify and commit**
+
+```bash
+tests/quickshell/default-apps-contract.sh
+tests/quickshell/applications-settings-contract.sh
+tests/quickshell/settings-pages-contract.sh

+- Produces: the same public `Settings.qml` properties, now each reading `DesktopPreferences.get("key")`, and controls routed to weather/vitals, notifications, and capture pages.
+
+- [x] **Step 1: Write failing contracts**
+
+Require all ten `Settings.qml` properties to use `DesktopPreferences.get()` exactly. Require every listed page root to be `SettingsPage` and reject its copied root `Flickable` scaffold. Require weather/vitals controls on `HomePage`, notification controls on `NotificationsPage`, and capture directory/encoder controls on `ScreenIntelligencePage`; every schema-bound control uses a shared row and writes only through `SystemSettings.commitPreference` via that row.
+
+- [x] **Step 2: Run contracts to verify RED**
+
+```bash
+tests/quickshell/settings-hardcoded-values-contract.sh
+tests/quickshell/settings-pages-contract.sh
+```
+
+Expected: fail on hardcoded properties and copied page scaffolds.
+
+- [x] **Step 3: Implement controls and migrate scaffolds**
+
+Use `ChoiceRow` for `temperatureUnit`, `screenshotDir`, `recordingDir`, and `recorderArgs`; use `SliderRow` for numeric refresh, timeout, history, and toast limits. Give `notificationTimeoutCriticalMs` `zeroLabel: "Never"`. Preserve all specialized buttons, service status rows, display diagnostics, permission/privacy explanations, and GNOME handoff actions. Convert genuinely read-only rows to `TextRow`; delete only rows superseded by working controls.
+
+- [x] **Step 4: Run focused and full suite, then commit**
+
+```bash

+tests/quickshell/settings-pages-contract.sh
+tests/quickshell/settings-preferences-contract.sh
+tests/quickshell/settings-search-contract.sh
+```
+
+Then run every `tests/quickshell/*.sh`, every `tests/hypr/*.sh`, and all three `tests/quickshell/*_test.py` files sequentially.

+# Settings Home & Phone Completion Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Finish the Home & Phone Settings page on Panama's shared Settings vocabulary and give the global reset path a named, durable Home preference API.
+
+**Architecture:** `HomePhonePage` adopts `SettingsPage` for the shared scrolling/title/lede scaffold while retaining its specialized catalog, reorder, alias, and phone controls. `HomePreferences.resetHomeDefaults()` becomes the sole Home-store reset boundary: it returns the store to fresh-install state and writes immediately so `SystemSettings.restoreDefaults()` can call it without mutating aliases.
+
+**Tech Stack:** Quickshell 0.3 QML, QtQuick, Bash contract tests, Hyprland.
+
+**Spec:** `docs/superpowers/specs/2026-08-17-panama-cohesion-design.md`
+
+## Global Constraints
+
+- Do not touch `SystemSettings.qml`, `PreferenceSchema.qml`, keybinds, or Claude's shared row implementations in this branch.
+- Preserve ordered Home favorites, aliases, first-four Control Center badges, search, drag and keyboard reorder, retry state, Home Assistant status copy, and BlueBubbles availability behavior.
+- Automated tests must not toggle or dim a real light and must not launch BlueBubbles.
+- New behavior follows red-green TDD; fixture and state directories remain isolated from the live desktop.
+- No mock phase and no new visual direction: this is cohesion work against the already-approved design.
+
+---
+
+### Task 1: Shared Home & Phone page and named reset boundary
+
+**Files:**
+- Modify: `config/dot/quickshell/config/HomePreferences.qml`
+- Modify: `config/dot/quickshell/home-preferences-harness.qml`
+- Modify: `config/dot/quickshell/modules/settings/HomePhonePage.qml`
+- Modify only if required for shared vocabulary compatibility: `config/dot/quickshell/modules/settings/HomeFavoriteCard.qml`
+- Modify only if required for shared vocabulary compatibility: `config/dot/quickshell/modules/settings/AvailableLightRow.qml`
+- Modify: `tests/quickshell/home-preferences-contract.sh`
+- Modify: `tests/quickshell/home-phone-settings-contract.sh`
+
+**Interfaces:**
+- Consumes: `SettingsPage { title; lede; default content }`, existing `SettingsCard`, `SettingRow`, `ActionRow`, `TextRow`, `HomeAssistant`, `SystemSettings.bluebubblesAvailable`, and writable `HomePreferences` adapter state.
+- Produces: `HomePreferences.resetHomeDefaults(): void`, which sets `favorites` to `[]`, sets `initialized` to `false`, clears stale save error state, and invokes `preferencesFile.writeAdapter()` immediately after stopping the debounce timer.
+
+- [ ] **Step 1: Write failing contracts**
+
+Add `reset()` to the isolated `home-pref-test` IPC harness. Extend `home-preferences-contract.sh` to seed aliases/order, invoke reset, and require both IPC state and `panama-home.json` to become exactly `{"initialized":false,"favorites":[]}` without waiting for the 180 ms debounce interval. Extend `home-phone-settings-contract.sh` to require `SettingsPage {`, `title: "Home & Phone"`, and the existing lede through `lede:`, while rejecting the copied root `Flickable` scaffold.
+
+- [ ] **Step 2: Run contracts to verify RED**
+
+```bash
+tests/quickshell/home-preferences-contract.sh
+tests/quickshell/home-phone-settings-contract.sh
+```
+
+Expected: the preference contract fails because `reset` is missing; the page contract fails because the page still owns a copied `Flickable` scaffold.
+
+- [ ] **Step 3: Implement the reset API and shared page scaffold**
+
+Implement this public boundary in `HomePreferences.qml`:
+
+```qml
+function resetHomeDefaults(): void {
+    persistTimer.stop();
+    values.favorites = [];
+    values.initialized = false;
+    root.saveError = "";
+    preferencesFile.writeAdapter();
+}
+```
+
+Replace the `HomePhonePage` root `Item` plus nested `Flickable`/title/lede scaffold with:
+
+```qml
+SettingsPage {
+    id: root
+    objectName: "home-phone-page"
+    title: "Home & Phone"
+    lede: "Choose what appears in Control Center and keep phone continuity close at hand."
+    // Existing SettingsCard content remains in order.
+}
+```
+
+Use shared `ActionRow` or `TextRow` only where their single-action/read-only contracts preserve all current status and accessibility behavior. Keep specialized rows when the shared primitive would lose information.
+
+- [ ] **Step 4: Run focused contracts to GREEN**
+
+```bash
+tests/quickshell/home-preferences-contract.sh
+tests/quickshell/home-phone-settings-contract.sh
+tests/quickshell/settings-pages-contract.sh
+tests/quickshell/settings-rows-contract.sh
+tests/quickshell/settings-commit-reset-contract.sh
+```
+
+Expected: every command exits 0; no test launches BlueBubbles or changes a real Home Assistant entity.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add config/dot/quickshell/config/HomePreferences.qml \
+  config/dot/quickshell/home-preferences-harness.qml \
+  config/dot/quickshell/modules/settings/HomePhonePage.qml \
