 ## [Unreleased]
 
+## [v0.51.173] — 2026-05-30 — Release ES (stage-batch55 — Windows path/journal safety + pin-quota snapshot fix + tool-card paging anchor + sidebar dedupe + quieter tool cards)
+
+### Fixed
+
+- Windows native runs now skip the POSIX-only turn-journal directory fsync instead of raising `AttributeError` for missing `os.O_DIRECTORY` on every submitted turn (#3170).
+- `/api/media` now treats Windows cross-drive `commonpath()` comparisons as non-matches instead of 500ing when media paths and allowed roots live on different drives (#3171).
+- Hidden pre-compression snapshots no longer keep stale pin state or count toward the visible pinned-session quota (#3181).
+- Tool-call cards stay anchored when scrolling back through paginated history; legacy session-level tool-call indices are rebased to the returned message window and the browser refreshes tool-call anchors whenever a larger history window is loaded (#3120).
+- Avoid duplicate sidebar rows when a compressed session completes after both the preserved snapshot id and continuation id are already present in the session list.
+
+### Changed
+
+- Restored the legacy compact tool-call card chrome by removing the persistent "Tool output" badge and returning the left rail to the muted border treatment. This keeps tool activity visually quieter while preserving the existing collapsible tool details.

 - Workspace path autocomplete now preserves `~/` suggestions while browsing under the user's home directory (#3173).
 - CLI-sourced cron sessions that were squeezed past the default sidebar window now stay addressable under their project chip via a dedicated cron-only lookup pass (#3172).
