Keep the serial connection and lease intact while providing a separate,
bounded admin terminal with explicit open and close controls. Fence
retained
terminal state across sessions and add fit-readiness retries with
regression
coverage.
- Require current admin cookie sessions, Origin checks and single-use
tickets
- Reuse the shared console with session-aware authorization and slot
allocation
- Add HTTPD-owned I/O, bounded buffering and revocation cleanup
- Prevent LRU eviction of serial clients and stale admin socket closure
- Reject unsupported web-shell mutations before side effects
- Add host regressions, a smoke client and resource accounting
Validated by user sign-off after a 15-minute full-client soak at 230400
baud, with a few broker drops under heavy output. Browser UI remains
for Phase 8D.6; numeric memory reserves remain open.
The user confirmed successful empty-Enter and soak testing, closing
8D.4 while leaving numeric reserve gates open and advancing the next
planned work to 8D.5.
Add bounded login challenges, CSRF/origin enforcement, logout, and
session-bound WebSocket admission. Isolate private HTTPD access behind a
version-guarded adapter and add focused host coverage. Also let empty
admin
SSH input reach the normal console handler.
