+## Release process
+
+1. `./release.sh <version>` — builds, zips `SimpleTopBar.app` to
+   `dist/SimpleTopBar.zip`, and prints its sha256 (it does not tag or upload).
+2. Commit and push `main`.
+3. `tea releases create --tag v<version> --asset dist/SimpleTopBar.zip --repo TZGyn/simpletopbar --login gitea.tzgyn.dev`.
+4. Bump `version`/`sha256` in `~/.cache/homebrew-tap/Casks/simpletopbar.rb`,
+   push, then `git -C /opt/homebrew/Library/Taps/tzgyn/homebrew-tap pull --ff-only`.
+
+**Always print the upgrade script after any release or version bump** — the user
+wants it in the final answer every time. Keep it to the cask upgrade commands
+(see the README release section for the exact block), because the app is
+installed through the tap.
+
+## Status item placement (why not MenuBarExtra)
+
+On a full menu bar, a newly created status item is placed leftmost, which on a
+notched MacBook is under the notch and therefore invisible. `MenuBarExtra` gives
+no control over this, so the app creates its own `NSStatusItem` and:
+
+- Sets `autosaveName = "SimpleTopBar"`.
+- On first run, writes `"NSStatusItem Preferred Position SimpleTopBar" = 100`
+  into `UserDefaults.standard`. This private-ish key is what macOS reads to
+  place the item, and 100 lands it at the visible right side. Because it is only
+  written when absent, the user's own ⌘-drag wins and persists via the autosave
+  name.
+
+`--diag` runs full startup and writes every status item's AX position to
+`/tmp/simpletopbar-items.txt`; use it to verify the icon is not under the notch
+(x should be ~1200, not ~765).
+
+## Hiding other menu bar items
+
+`MenuBarHider` creates a zero-width spacer `NSStatusItem` at launch and grows its
+length to `hiddenLength` (10_000) to push the icons on its left off-screen. It is
+**on by default** (`hideMenuBarItems` defaults to true, then persisted). Its
+preferred position controls where the hidden/kept boundary lands:
+
+- Seed **250** (default) puts the boundary just left of Wi-Fi, so every
+  third-party app icon goes to x < 0 (cmux, Kapture, moomoo, WireGuard,
+  TextInputMenuAgent, Now Playing) while **Wi-Fi (x≈1173), Spotlight, Clock,
+  Battery, Control Center and our hamburger stay visible**.
+- Verified with `--diag-hide` across positions 100–400. Below ~200 Wi-Fi gets
+  hidden too; above ~300 app icons (Now Playing, TextInput) leak back.
+- `debug.spacerPos` (Double) overrides the seed for tuning without rebuilding.
+- Pressing a tray tile calls `MenuBarItemManager.press`. A hidden item sits
+  off-screen, and its menu opens off-screen too (verified with `--diag-press`:
+  the menu window lands at negative x). So press briefly `suspend()`s the hider,
+  waits ~0.2s for the layout to settle, performs the accessibility action
+  (`kAXPressAction`, then `kAXShowMenuAction`), and `resume()`s ~0.1s later. The
+  menu is its own window anchored at the item's on-screen spot, so it survives
+  re-hiding.
+- **Cannot reveal a single icon.** The spacer hides a contiguous block to its
+  left, so a press can only reveal the whole block. Isolating one item would
+  need either per-item ordering control (not available) or covering the icons
+  with an overlay window instead of moving them off-screen.
+- **Order matters**: `AppDelegate` must call `setupStatusItem()` *before*
+  `MenuBarHider.shared.prepare()`. If the hider contracts the bar first, the
+  hamburger is created into the collapsed space and lands off-screen.
+- **Wi-Fi/Spotlight/Clock/Battery/Control Center cannot be hidden**: macOS pins
+  them to the far right and a third-party item can never be inserted to their
+  right, so the spacer has nothing to push them with. This is a macOS
+  constraint, not a bug.

 macOS has no public API to move another app's status item. The **Hide items from
 the menu bar** toggle uses the spacer technique: a zero-width status item is
-created at launch whose length is expanded to push the items to its left
-off-screen. This is reliable only when SimpleTopBar starts at login (its spacer
-then sits to the right of later-launched apps' items) and may need re-toggling
-after items move around. It is off by default and always undone on quit; if the
-app dies, macOS removes the spacer automatically.
+created at launch whose length is expanded to push the other icons off-screen so
+they only live in this panel. It is **on by default** (the choice is
+remembered), always undone on quit, and if the app dies macOS removes the spacer
+automatically.
+
+What it can and cannot hide:
+
+- It hides **other third-party apps' icons** (cmux, Kapture, WireGuard, input
+  source, Now Playing, …) so only your apps' icons leave the bar.
+- It **keeps Wi-Fi, Spotlight, Clock, Battery and Control Center**. The spacer's
+  boundary is tuned (preferred position 250) to fall just left of Wi-Fi, so the
+  Apple items on the right stay visible. macOS reserves that far-right area: a
+  third-party item can never be placed to the right of it, so those icons cannot
+  be pushed away even in principle. (Bartender and Ice hit the same wall and
+  cover the area with their own overlay bar instead.)
+- Newly launched apps are placed to the left of the spacer, so they are hidden
+  automatically.
+- Advanced: set `defaults write dev.tzgyn.simpletopbar debug.spacerPos -float <n>`
+  to move the boundary (larger = keep more icons; > ~400 starts leaking app
+  icons back into the bar).
