 | **8D.14 — Display settings** | **Implemented, host/build verified; target pending.** Typed local display configuration and explicit persistence via `local_ui_config`/generation-checked public UI APIs; [contract/evidence](phase8d14_implementation.md). | Host limits/storage/CLI-generation/activity/lifecycle regressions pass; actual save/reboot, absent-display and concurrent buttons/CLI target checklist remains pending. No I2C ownership changes or electrical diagnostics UI. |
 | **8D.16 — Broker client visibility and writer transfer** | **Implemented, host/build verified; independent parent review and target sign-off pending.** Admin-only detailed snapshot plus explicit confirmed assignment through existing dispatcher/broker; smallest owner changes add atomic lease-version/target validation and nonwrapping IDs. [Contract/evidence](phase8d16_implementation.md). | Host stale/disconnected/reused target and lease ABA rejection, one writer, admin denial, bounded/session-isolated results, lifecycle and UI non-mutation regressions pass. Concurrent physical USB/SSH/browser/full-mix and stack-margin checklist remain pending. No transfer on page open/selection; no8D.17/18 popovers/icons. |
 | **8D.17 — Serial/Wi-Fi quick popovers** | **Implemented, host/build verified; independent parent review and target sign-off pending.** UI-only reuse of completed typed endpoints through one settings DOM/controller, full-page link and shared validation; `web_ui`. [Contract/evidence](phase8d17_implementation.md). | Hover/focus/click/tap, Escape/outside dismissal, no opening/selection mutation, explicit Apply/Save, Network password exclusion; draft/session/pending-operation regressions pass. Full-page hover deliberately preserves its existing draft; explicit activation navigates that page. Optional geometry blocked by sandbox; real pointer/keyboard/touch/full-mix checklist pending. No duplicate backend/new settings scope/icons/8D.18. |
-| **8D.18 — Client/writer contextual dialogs** | Reuse 8D.16 for live client popover and confirmed Active writer dialog. | Accessible pointer/keyboard/touch paths; refresh preserves explicit selection safely; stale confirmation is rejected visibly; normal users retain only ordinary status. No new writer policy. |
+| **8D.18 — Client/writer contextual dialogs** | **Implemented, host/build verified; independent parent review and target sign-off pending.** UI-only reuse of8D.16 and8D.17's single host for live client popover and confirmed Active writer dialog. [Contract/tests/checklist](phase8d18_implementation.md). | Native pointer/keyboard/touch entrances; single-flight5-second live refresh/deadline, explicit selection preserved without lease-token renewal, sticky stale/absent rejection, full-page draft protection and focus-safe updates. Ordinary users retain only ordinary status.135 UI groups plus broad broker/auth/lifecycle regressions pass; real browser/device checks pending. No new writer policy/backend/icons/8D.19/later. |
 | **8D.19 — Ordinary service/session controls** | Typed service status and targeted disconnect/start/stop controls, excluding actions that cut off the invoking HTTPS session; start in existing service APIs and generation-safe snapshots. | Explicit scope/confirmation, stale target rejection, owner-safe execution and failure isolation. Stop/start and disconnect do not clear settings/identities. Split by service if more than one owner adaptation is necessary. |
 | **8D.20 — Self-affecting service actions and reboot** | Confirmed typed operations for connection-losing HTTPS/Wi-Fi/service actions and reboot, reusing lifecycle behavior established in 8D.7/8D.13. | Acknowledgement/pending-action handling is bounded, no duplicate action on UI retry, connection loss is explained, recovery and reconnect work. No new unbounded queue or certificate/key rotation yet. |
 | **8D.21 — Security/danger-zone settings** | Carefully separated HTTPS/SSH identity rotation/reset and any explicitly retained recovery-secret operation through existing security APIs. Enumerate allowed operations first; split HTTPS and SSH work into separate requests if both need owner changes. | Confirmation, secret-safe one-time responses, no routine private-key export, expected trust/fingerprint changes, bounded self-disconnect, no accidental configuration wipe. Bootstrap/unavailable-database recovery remain UART0-only. NVS encryption, secure boot, OTA, and new factory-reset semantics stay out of scope. |
