+- **8D.20 end-to-end integration complete (2026-09-13), host/build verified, independently reviewed; target sign-off pending:** Continuation found/preserved uncommitted backend/API/UI/tests beyond the prerequisite-only memory. Inspected and validated that integration, added send-return-at-deadline/request-storage-reuse/accepted-restart-expired-login regressions and explicit post-restart login wording. `web_lifecycle_settings.{c,h}` provides three optional current-admin routes, strict256-byte/four-receive typed stop/restart/reboot,128-byte snapshot/96-byte result, one login-bound slot/nonreused ID and one2-second ACK reservation. Synchronous send return then HTTPD ID callback then existing four-entry dispatcher, original-login/current-admin/post-validation30-second deadline, canonical generation/reserved stop/restart and narrow `esp_restart()` admission. No request/fd capture, no lifecycle on HTTPD, no lock/self-console-cleanup wait at reset. Lost HTTPD work stays singly reserved until callback or successful destruction; late/ABA work inert; failed stop retains canonical recovery. UI HTTPS/Reboot explicit confirmations,15-second whole requests, manual results, pending/unknown duplicate gate and no replay/restore; existing Network link/controller, corrected USB-vs-admin recovery wording.

+- **Historical 8D.20 lifecycle-owner prerequisite (2026-09-13), superseded by integration above:** Scope split before editing under plan600–800-line rule after finding missing HTTPS generation admission and stop/start reservation. `web_server.{c,h}` adds zero-wait secret-free management snapshot, conditional stop/restart under canonical mutex, saturated lifecycle generation across CLI ABA/counter clear and continuously reserved restart. Failed stop skips start; partial cleanup retains ownership and canonical recovery. Repeated init no longer clears retained invalid-state lifecycle failure. No new HTTP routes/UI/ACK handoff/typed reboot; these remain next authorized8D.20 integration, not complete phase delivery. Existing Network Wi-Fi controls must be reused; unrelated19 other-service and21 excluded. Initial worktree clean.

HTTPD never waits for SSH/wolfSSH; no new task/timer/stack/depth/socket/asset/config/dependency.36 handlers/six sockets.
