+- Open printer settings and job details by double-click, while preserving checkbox/button actions and text selection. Equivalent Settings and Details buttons remain available.
+- Use wider, window-responsive native dialogs for profile editing and structured job summary/event history.
+- Add sortable headers with printer Name ascending and job Created descending defaults. Creation time is preserved independently of status updates; missing historical creation times remain explicit.
+- Apply job ordering across the matching local history and bounded cloud queue preview before paging, using displayed labels and stable identifier tie-breaks. Sort indicators update only after a successful query.
+- Source verification and installed 0.1.6 acceptance are pending; no physical print is claimed for this UI work.

 - Compact printer/job tables, stable row selection, full-text details and bounded 50-row job pages with prefix search.
 - Client-managed computer/printer names, descriptions and locations synchronized to QQQ without changing physical queue identities.
 - Indexed history queries, 200-event recovery batches and bounded detail maintenance; synthetic 10,000/30,000-job regression coverage.

Only returned rows deserialize event JSON. Offset pages are live views: concurrent new jobs can move page boundaries, so refresh before assuming an unchanged list.
+The Jobs page queries SQLite rather than filtering the latest snapshot. Page size is bounded to 100, with SQL counts and status/printer/review filters. Jobs default to original creation time descending; clickable headers sort the full local history by creation time, title, printer, displayed status or format, with a deterministic job-ID tie. Search matches the start of a job ID, title or printer name; literal percent and underscore characters are escaped. Search fields have SQLite prefix indexes. Only returned rows deserialize event JSON. Offset pages are live views: concurrent new jobs can move page boundaries, so refresh before assuming an unchanged list.

The UI marks when the preview reaches its bound; its combined count is not an authoritative total for an arbitrarily large cloud queue.
+A bounded preview of up to 50 cloud-queued jobs interleaves with local history under the same selected sort order and keeps queued cancellation available before receipt. Matching local jobs suppress duplicate preview rows. The UI marks when the preview reaches its bound; its combined count is not an authoritative total for an arbitrarily large cloud queue. The merge reads at most 150 local candidates in bounded SQL pages, regardless of the requested offset, plus at most 50 cached queued jobs. Text ordering uses SQLite NOCASE (ASCII case folding, otherwise UTF-8 order) consistently for both sources; visible fallback labels and reviewed-status suffixes participate in ordering.
 
 Outbox delivery reads at most 200 ordered events per poll. The worker heartbeats and defers new claims until the previous backlog has drained. Interrupted-state recovery is also batched. Job details expose the latest 200 retained events. The legacy event-to-summary migration runs once, rather than grouping all events each time the service opens its store.
 
 Default detail retention is 30 days or 300,000 jobs, with at most 250 eligible jobs pruned per maintenance pass. Runtime schedules this maintenance once per minute. Pending events, active submissions, unreviewed failures and every uncertain outcome retain their evidence. Operator review never changes delivery status. Terminal summaries remain for duplicate suppression even after event detail is pruned; the database therefore has no fixed lifetime size ceiling. SQLite reuses freed pages; retention does not promise that its file immediately shrinks. Monitor disk use and resolve operational exceptions instead of deleting a live journal.
 
+Creation time is separate from the latest status-update time. Receipt captures the normalized server creation timestamp once; later events and repeated claims preserve it. The one-time migration uses the earliest retained event timestamp, falling back to the stored update timestamp when old detail is gone. An absent historical timestamp remains unknown rather than inventing a date. The 0.1.6-rc.1 gate passed 211 tests (42 Core and 169 Windows/CLI), including the creation-time migration and every header order across 10,000 rows, both directions and distant pages. Locked restore and the build completed with zero warnings/errors. The 204-test timing observations above describe the prior source.

 AppKit retains its local-midnight daily filename rotation and shared log viewer. Machine-wide settings default to 30 days and 20 MiB per daily file; supported ranges are 1–365 days and 1–100 MiB. Service and companion use one cross-process lock for appends, settings, retention and clearing.

+## Current checkpoint: 0.1.6 source verification
+
+Corrected 0.1.5-rc.1 from 1d1727a is installed and opened. Installation returned 0 without a reboot; credential bytes were retained, the service restarted, and four printer queues were discovered. Management, profile, job-page and log-settings queries and the branded shortcut passed. All 12 existing native UI checks have passing results across the initial 10 passes and a focused two-test rerun. Exact-source CI 41127963112 passed 204 tests and MSI packaging. The existing cloud connection is offline.
+
+The 0.1.6 changes implement inline printer details, double-click settings/details, wider responsive dialogs and sortable headers. Printers default to friendly name ascending; jobs default to immutable creation time descending. SQL sorts the complete history, with bounded pages and a bounded merge of queued jobs. Creation-time migration preserves existing evidence. The full gate passed 211 tests (42 Core and 169 Windows/CLI), locked restore, and zero build warnings/errors. Packaging and installed UI acceptance are next. No physical print was sent for this scope.
+
+Root owns packaging, the normal UAC upgrade and publication after verification. Agent-owned source is frozen for the gate. Older checkpoints below are historical and do not describe the current installation.

The earlier MSI MajorUpgrade schedule removed0.1.4 outside the rollback transaction, leaving its service/app absent. Protected device state and pre-upgrade backup remain. Recovery uses the verified installer artifact from passing CI41076156859 under cloud-printing-integration/runs/recovery-014/verified-ci; Restore-014.ps1 was launched through normal UAC, but Windows canceled elevation before it started. The user has been asked to reply retry for a fresh prompt; no elevation is now pending. Do not claim installation/recovery complete until result.json confirms it. Root owns recovery/install. The corrected source passes204tests (39Core+165Windows/CLI): Start menu checks allow deletion-only inherited user grants while rejecting content writes, and MajorUpgrade now uses afterInstallInitialize. Build outputs are isolated per numeric version to preserve prior recovery installers. Remote CI for b45a906 failed one timing-based heartbeat assertion; its corrected test waits for observed traffic while retaining the no-claims pause invariant. The strict protected updater-data ACL policy remains unchanged.

+## 0.1.6 review corrections
+
+- Replaced a single unbounded printer text block with labeled fields and a three-line description preview. Actions appear first; the full description remains in Settings.
+- Excluded buttons, checkboxes, editable/selectable text and the inline-details subtree from row double-click handling. Double-clicking text to select a word should not launch an editor.
+- Kept wide-dialog size resources scoped to each dialog. Content dimensions follow `XamlRoot.Changed` while open, and the handler is removed on close.
+- Reused the displayed printer status for sorting. Job ordering uses human-readable status labels and the same title/printer fallbacks shown in rows.
+- Committed job sort arrows and accessible direction labels only after a successful query, avoiding old rows under a new order indicator when the service fails.
+
+These corrections were confirmed by source review. Their build, automated regressions and installed interaction checks are pending for 0.1.6.
+
 ## Next installed checks
 
 - Inspect table headers/columns at small and large window sizes; select rows with keyboard, change filters/pages, and confirm full long values remain available.
+- Resize an open printer-settings/job-details dialog; double-click selectable expanded text; operate the Shared checkbox; verify those actions do not unexpectedly open a second dialog.
+- Confirm Name ascending and Created descending defaults, both sort directions across multiple pages, and a failed query retaining the prior applied indicator. Ensure a status update does not change a job's Created value.
 - Save and clear device/printer metadata, restart the service, and verify synchronization without changed IDs or queue names.
 - Confirm log viewer reuse, daily-limit feedback, retention settings and diagnostic-only clearing.
 - Exercise unavailable-service and action-error feedback, then verify stale polls cannot overwrite newer operations.

 ## Historical observations
 
-The early build had a long scrolling setup page, duplicated log viewers, an expanded enrollment form and refresh that rebuilt controls. Later reviews identified missing service controls, actions, startup preference and accent constraints. These observations explain completed changes and are not descriptions of the current source. Installed evidence is scoped above rather than inferred from source review.
