-is the pattern reference), plus the carry-over from v1.4.9: structural First-Frame-Layout rewrite if the v1.4.9 selective
-defers turn out to be too narrow once user-side regressions surface. Lazy-Window-Init naive is **not** in scope — the
-v1.4.9 Stage-2 diagnose falsified that path (`WindowSystem.windows` is non-thread-safe, Game-Freeze under reload stress,
-no measurable HITCH delta). A clean DI-container adoption (Lightless `PluginHostFactory` pattern) belongs in v1.5.x and
-will revisit the question with the right threading model.
+**DI-container adoption.** Microsoft.Extensions.Hosting plus `ILogger<T>` modelled on Lightless's `PluginHostFactory`
+pattern. The v1.4.x Polish-Sweep series is closed; v1.5.0 starts the structural cycle that the smaller F12.x indirection
+shims (`IPluginLogProxy`, `IPlatformUtil`) were paving the way for. After that, the Wine/Linux scroll-rubber-band spike
+deferred from v1.4.10 (Reserve-A cancelled — Windows users never saw it) plus the First-Run-Wizard rework that lets users
+opt into the curated defaults instead of just picking a privacy profile.

+## v1.4.10 — Symbol-Picker and Tell-History Fix (released 2026-05-16)
+
+Eleventh and final sub-patch of the v1.4.x Polish Sweep series. Symbol picker for the chat input — popup with two tabs
+(161 FFXIV PUA glyphs via Dalamud's SeIconChar plus 97 server-verified BMP symbols probed through `/echo` and `/say` in
+a four-round whitelist build) — cursor-aware splice, multi-insert, recent-used strip across both tabs, Settings toggle
+in Chat → Message behaviour. Mid-cycle hotfix for pinned auto-tell tabs: PreloadHistory used to cap the SQL scan at
+500 rows regardless of the user's `AutoTellTabsHistoryPreload` setting, so active users with many partners lost the
+backlog of less-frequent pinned partners; the cap is gone, the `(Receiver, Date)` index keeps SQL fast, the client-side
+loop respects the user setting as the upper bound. Slash-command teardown cleanup wires the v1.4.9 wrappers through
+private fields so dispose detaches the live registration instead of re-registering with identical args. The original
+Reserve-A `ImGuiListClipper` refactor for `DrawMessages` was cancelled after cross-platform smoke showed the scroll
+rubber-band is a Wine/Linux render-pipeline quirk, not universal — Windows-side testing on v1.4.9 confirmed no lag.
+Migration v17 stays.
