From the fresh whole-branch review of the identity gate (With fixes; no
Critical, four Important):
1. A drive pulled while a line ran: the drives are looked at before every
prompt (sk_v4_identity_check_now), so no prompt is shown once she is
gone and what was typed after the pull does not run as Zuse.
2. Pulled while a line WAITS: the wait is ended at logout, by an empty
line, and not carried into her next session (Captain Bob, 2026-10-26:
"end the waiting line at logout"); re-attaching brings the prompt back.
3. EMERGENCY_CONSOLE_ENABLED: v4 honours it as v3 does -- a bring-up build
has a prompt with no drive (boards/BRINGUP.md A2).
4. Keys typed at a headless machine are read and dropped, not run as
whoever logs in next. (v3 has the same gap, sk_repl_headless_wait;
reported, not changed.)
Each a QEMU session red then green (amd64): midpull 111650 -> 112953,
waitpull 111907 -> 113154, emergency 112524 -> 113609, typeahead
112248 -> 113359; headless 113800 and hotplug 114043 still pass.
Accepted: three clean qemu boots to [zuse@Hera] ok>, POST 538/538,
dict_hash 0xfec8c47cfc6f437f on all three; hotplug on aarch64 and
riscv64; make -C v4 test test-32 sanitize hosted-check EXIT 0;
make -C v4 test-32 0 failures.
