Scroll test — run in order, ~60s, tell me which pass/fail

W1. Stay in this chat window: mouse wheel — does the chat scroll? W2. Same window: PgUp / PgDn keys — does the chat scroll? W3. Ctrl-A 1 → test shell with 200 numbered lines: wheel — does it scroll? W4. Ctrl-A 0 to come back. Anywhere: Ctrl-A [ then wheel or arrows; q exits.

Notes:

• Copy mode (Ctrl-A [) and PgUp/PgDn are keyboard-only paths that cannot depend on mouse events. One of them surviving = reading is unblocked.
• All buffers are now 10000 lines.
• A deeper fix (termcapinfo in ~/.screenrc) activates on the next natural relaunch — I am NOT restarting your live screens.
