 UART0 and authenticated `admin` SSH sessions use the same registered command implementations through one serialized dispatcher. Admin SSH exposes the full operational registry, including interactive prompts, network diagnostics, reboot, and HTTPS/SSH material mutation. Create the first administrator through normal `user add <username> admin` on physical UART0; explicit recovery of an unavailable database is UART0-only. Admin SSH also rejects generating a replacement password for its own account so the one-time value cannot be lost when the session is revoked. Run `help` for root commands and `<group> help` for a group summary. Configuration changes are RAM-only unless explicitly saved.
 
-Browser-admin uses the same dispatcher with temporary 8D.7 restrictions. It now supports deferred **`reboot`** and **`web stop`** in addition to admin-only `exit`. The control task waits up to ten seconds for application output drain plus 200 ms; acknowledgement delivery is best effort, not confirmed receipt. Input observed during deferral is discarded. `web stop` closes both browser routes; restart HTTPS via UART0/admin SSH `web start` and sign in again. Reboot affects all transports and loses RAM-only changes. The second slice also permits exact parsed **`web certificate rotate --force`** (equivalent quoting accepted, no missing force or extra arguments). After drain/delay it queues a typed action on the existing dispatcher; pending input remains discarded until completion. This does not bound dispatcher wait or certificate/NVS/lifecycle execution time. Certificate commit precedes HTTPS stop/start: early generation/persistence errors skip restart, stop failure retains ownership and skips start, and later lifecycle failure does not undo the new persisted identity. Success closes both browser routes and any web writer lease; verify/trust the new certificate through a trusted channel and sign in again with unchanged account credentials. USB/UART0/SSH remain usable; use UART0/admin SSH for stop/start recovery if needed. Other `web` forms besides `web status`, `web stop` and this exact rotation remain blocked (including certificate info and reset; legacy credential commands are removed). User mutations, Wi-Fi/mDNS mutations and restricted SSH lifecycle commands remain unavailable from browser admin. See `phase8d7_implementation.md` for the exact remaining policy and target-validation status.
+Browser admin uses the same dispatcher with a [narrower parsed frontend policy](web_administration.md#browser-shell-policy), independent of typed Settings permissions. It supports bounded deferred `reboot`, `web stop`, exact `web certificate rotate --force` and owner-relative `exit`. Drain (up to ten seconds plus 200 ms) is best-effort application-buffer acknowledgement, not peer receipt or an execution deadline; pending input is discarded. Certificate work runs on the existing dispatcher through the shared service-before-identity reservation, commits before stop/restart and never rolls back a committed identity after lifecycle failure. Failed stop retains ownership and skips start. Verify changed trust through UART0 `web certificate info`, recover with UART0/admin SSH `web stop` / `web start`, then sign in freshly. HTTPS-only actions leave SSH/native USB/UART0 independent; reboot affects every transport and loses unsaved RAM.

+Browser `web` allows only status/stop/exact forced certificate rotation; `wifi`/`mdns` allow status only. Browser `user` allows status/list/show and interactive add/password plus forced role/delete for **other accounts**, not self/generated/key/recovery commands. Restricted SSH stop/disconnect/reset/host-key mutation remains unavailable in the browser shell. Typed Accounts/Network/SSH settings separately provide their documented bounded workflows; this is not shell parity. See [web administration](web_administration.md) for lifecycle/API ownership and uncertainty.

 When both transitions are enabled, `off-seconds` must be greater than `dim-seconds`. Applying settings counts as local UI activity. At normal boot, an initialized OLED shows a bounded five-second identity animation before the status UI begins; it scrolls the device name in yellow and draws the compact upright-terminal logo in blue. A missing OLED remains nonfatal; after reconnecting it safely, one new button press requests a bounded reprobe and is consumed without navigating.
 
-Display settings require an available local UI task, not an attached panel. CLI and browser **Settings → Display** share the public configuration owner; concurrent mutations can report busy, and browser operations reject an intervening configuration edit rather than overwrite it. Save persists working RAM, not browser drafts. Load selects defaults when saved storage is absent/incompatible without rewriting NVS. Reset storage failure leaves RAM unchanged (commit-before-publication, no RAM rollback). Browser timeout/navigation does not cancel already-admitted work; Check Result and Refresh before retrying.
