 ## Manual GUI checklist
 
-The GUI is a style spike until Phase 4: the table and wheel are painted from a
-demo `RouletteView`, and no network connection is made. Run it on Linux and on
-Windows 10 before approving the look.
-
-1. `cargo run -p zagan-bet-gui` at 1440x900, then at 1920x1080. The header
-   keeps its right margin at both sizes and shows ONLINE, host, ping, account
-   and balance; the table is centred and the sidebar is full height.
-2. The felt shows 0, the 3x12 numbers, dozens, columns (each a quarter of the
-   row) and the six outside cells. Chips sit on their targets: a straight in
-   the cell, a corner on the lattice crossing, an outside bet in its box.
-3. Hover a number: a translucent chip of the selected denomination appears.
-   In the inner half of a cell it is a straight (one cell tints); near an edge
-   it snaps to a split (two cells tint) and near a corner to a corner (four
-   cells tint). Hovering the dozens, columns and outside boxes moves the
-   preview there.
-4. Left click adds the chip where the preview is; right or middle click takes
-   one chip of that value back, dropping the row when it reaches zero. The
-   slip and total follow every change. C or CLEAR empties the slip.
-5. Space or SPIN animates the wheel for about 2.4 s and stops with the winning
-   pocket under the pointer. The winning cell gets a gold outline and LAST
-   gains a dot. RESULT names the number and colour, WON shows the amount paid
-   and the net for the round, and a losing spin says NO WIN. SPIN, CLEAR and
-   the chips are disabled during the spin.
-6. Placing a chip after a result starts the next round: the payout row goes
-   back to PLACE YOUR BETS while the wheel stays where it stopped. Resize to
-   1100x720: the sidebar scrolls, nothing overlaps the header, and the table
-   keeps its aspect ratio.
-7. Compare the 1080p window against the approved reference screenshots.
+The desktop frontend shares `ClientCore` and the data directory with the
+terminal client; a saved login from one signs in the other.
+
+1. `cargo run -p zagan-bet-gui` (or `-d <dir>` / `--unsafe`). The connect
+   screen lists remembered hosts with short fingerprints.
+2. First contact: the fingerprint modal appears before any credentials. Cancel
+   leaves the connect screen; Trust continues to the login screen.
+3. Register, then log in with "Remember this login". The lobby shows the host,
+   ping, account, balance and the four games; quit and reconnect: the stored
+   login signs in without asking.
+4. Each game: place a bet or deal, play a round, and confirm the balance and the
+   header update. Slots shows reels and win lines; roulette spins the wheel and
+   reports the payout; blackjack draws suits and settles; crash draws a smooth
+   curve and cashes out. While the reels or wheel turn, the balance shows the
+   stake already deducted; the payout appears only when they stop. A spin or
+   deal the server refuses (for example an insufficient balance) shows the
+   error and must not animate the reels, the wheel or the curve.
+5. Sidebar actions never move while the slip grows. CLEAR empties the slip;
+   right or middle click on the felt takes one chip back; C clears and space
+   spins in roulette.
+6. Leaving a live blackjack hand or crash round asks for confirmation, then
+   forfeits. Leaving an idle table returns to the lobby.
+7. HISTORY shows the last plays; SHOW changes the limit. LOG OUT returns to
+   the login screen but stays connected; Disconnect drops the session (the
+   saved login survives).
+8. Run the client against a server of another MAJOR.MINOR version: the
+   mismatch screen names both versions and the download page. A changed host
+   key stops the connection and offers forget-and-reconnect.
+9. Resize to 1100x720: the sidebar scrolls, the actions stay reachable, and
+   the board keeps its aspect ratio.
