 ## Session broker

+- **8D.16 management:** `session_broker_get_management_snapshot()` copies compact eight-client rows plus writer/lease generation atomically with zero wait; `session_broker_assign_writer_current()` compares generation and target under the force-writer lock. 29-bit client generations retire slots instead of wrapping; saturating lease generation fences ABA, survives counter clear, and leaves ordinary recovery available. Actual canonical regressions extend `tests/session_broker_diagnostics/run.py`. Full contracts/wrap analysis: `docs/phase8d16_implementation.md`.
+
 **Responsibility:** mediate all transport access to the serial service; provide one writer lease and multiple isolated observers.

 ## Web and WebSocket serial

+- **8D.16 Broker (2026-09-13):** `web_broker_settings.{c,h}` owns optional admin-only GET `/api/settings/broker`, GET/POST `/api/settings/broker-operation`; existing dispatcher queues only IDs. `web_ui.c` adds Serial/Display-style full-page rows and explicit confirmed assignment, no mutation on view/selection. 256-byte/four-receive request,2048-byte snapshot,96-byte result, one login-bound slot/no timer;33 handlers/six sockets, unchanged tasks/stacks/queue/assets/CPU160/combined WS send.

 - **Current 8D.12/8D.13 — user functional sign-off 2026-09-08, including Settings presentation:** `web_network_settings.{c,h}` owns optional admin-only GET `/api/settings/network` and GET/POST `/api/settings/network-operation`; `web_ui.c` supplies Network, UTF-8/hex SSID editing and explicit transient-secret/connection controls. `wifi_manager` owns generation-checked secret-free snapshots/patch/save/stored-only load and radio transitions; `mdns_service` owns independent conditional hostname persistence, with manager reannouncement. Existing dispatcher receives IDs only. 768-byte request/2,048-byte snapshot/128-byte result, one slot/one-second timer with 30-second queued expiry plus scheduling latency; no hard cancellation. 27 handlers/six sockets, no task/stack/queue/schema growth.
