Record what landed (S1 raw evdev tap, S4-core VT graphics-mode op, S5 seatd local package; all compile-checked, boot-validation P0-gated) and correct the Defect-3 framing: fbcond is a byte-queue + CR/LF + special-key escapes, not a second canonical line discipline (ptyd is the only one), and the console login works — so the old "collapse two disciplines" console surgery is deferred as unnecessary and risky. Grab arbitration + compositor wiring remain gated on the Mesa desktop bring-up.
