 ## SSH

+- **8D.21 SSH identity extension:** `ssh_security.{c,h}` owns zero-wait atomic public metadata and task-bound/nonreused identity reservations shared by direct rotate/reset, crypto/NVS outside security locks. `ssh_transport_replace_identity()` shares canonical CLI/deferred SSH combined service-before-identity admission, existing command-mutex reservation and stop→commit→conditional restart; failed stop skips mutation/start, context retained until owner retires every slot, start rejects orphan handles. `web_ssh_settings.c`/existing `web_ui.c` SSH controller/routes add P-256 fingerprint/algorithm/both generations and confirmed rotation (same256/768/96-byte bounds, manual15-second/no-replay result flow); no browser Reset/recovery/export or shell-policy change. PASS real-security+combined-owner5, runtime-retention, management5, cookie SSH7+shared/all variants, UI158 and broad HTTPS/console/transport regressions. Final100,556 RAM/1,828,573 flash (+24/+3,500), CPU160 unchanged. Full21 allowed HTTPS+SSH implementation complete; independent SSH parent review and target acceptance pending.

 - **8D.19 first service slice:** `web_ssh_settings.{c,h}` adds optional admin-only GET `/api/settings/ssh`, GET/POST `/api/settings/ssh-operation`; existing dispatcher queues only IDs to one login-bound slot. `ssh_transport_get_management_snapshot()` copies published state without owner wait/stack scan; `ssh_transport_manage_current()` checks saturated service generation under existing command mutex and exact session ID under SSH lock before canonical lifecycle/external-close admission. Exhausted session slots retire instead of wrapping. `web_ui.c` adds confirmed SSH-only Settings, sticky stale selection,15-second requests/manual Check Result/Refresh.36 handlers/six sockets/no new tasks/timers/depth/stacks/assets; CPU160 and8D.18 preserved. Tests `tests/ssh_management/run.py`, cookie `--ssh`, dispatcher, lifecycle27 and UI143. Contracts/resources/remaining8D.19 service audit/target checks: `docs/phase8d19_implementation.md`. SSH slice implemented/host/build verified; parent review/target sign-off pending, not full8D.19.

 **Responsibility:** authenticate SSH, route users to serial and administrators to the command dispatcher, and own wolfSSH lifecycle.
