+    **v1.5.0 — DI Foundation and Service Refactor (2026-05-17)**
+
+    Major architecture cycle. The plugin bootstrap moves to a
+    generic-host DI container (Microsoft.Extensions.Hosting +
+    IServiceCollection) modelled on Lightless Sync. Service logging
+    moves from a static Plugin.LogProxy locator to typed
+    Microsoft.Extensions.Logging.ILogger<T> via constructor injection,
+    bridged over Dalamud's IPluginLog by a custom DalamudLogger trio.
+
+    What changes under the hood:
+
+    - 18 instance-class services migrate to ILogger<T> via constructor
+      injection across four slices: data layer (MessageStore,
+      MessageManager, AutoTellTabsService), IPC and integrations
+      (HonorificService, IpcManager, TypingIpc, ExtraChat, the three
+      GameFunctions classes), UI window layer (ChatLogWindow,
+      DbViewer, Popout, three settings tabs), and root (Commands,
+      ThemeRegistry, PayloadHandler).
+    - Plugin.LogProxy stays in place for the eight buckets ctor
+      injection cannot reach: static helpers (EmoteCache,
+      AutoTranslate, MemoryUtil, WrapperUtil), Dalamud-reflected
+      types (Configuration), the Message data class, and instance
+      classes that only log from static methods (FontManager, one
+      GameFunctions site).
+    - Plugin.cs finishes at 1012 lines — virtually identical to the
+      pre-cycle 1013. The new Phase-1 host build and Plugin.X bridge
+      wiring trade out exactly the service and window allocations
+      that previously lived in LoadAsync.
+    - Cross-plugin baseline confirms no performance penalty against
+      Chat 2: HellionChat first-frame HITCH 77 ms median, Chat 2
+      74 ms median. Lightless and XIVInstantMessenger sit around
+      7 ms by deferring their font-atlas build past Finished
+      loading — that pattern is the v1.5.1 follow-up.
+
+    User-visible:
+
+    - Slash-command insert fix: pasting a slash command into the
+      chat input (Friend List "/tell" action, plugin-driven inserts
+      from Artisan, AllaganTools etc.) now replaces the existing
+      input instead of concatenating. Cherry-picked from ChatTwo
+      upstream ee7768ac with namespace adaptation.
+
+    Migration v17 stays (no schema bump).
+
+    Based on Chat 2 1.35.3 (upstream Infiziert90/ChatTwo, EUPL-1.2).

-    **v1.4.7 — Backlog Cleanup and Mid-Features (2026-05-13)**
-
-    Eighth sub-patch of the v1.4.x polish-sweep series. First
-    user-visible feature bundle since v1.4.5 — pinned tell tabs that
-    survive relog, opt-in Honorific glow rendering, and a configurable
-    sidebar.
-
-    - TempTell Pin: right-click a TempTell tab in the sidebar to pin
-      it. Pinned tabs survive relog, keep their conversation history
-      (loaded on demand from the message store), and stay bound to
-      the same /tell partner. Hard cap of 5 pinned tabs in a pool
-      separate from the 15-tab auto-tell pool — total ceiling is 20
-      tabs. New 'Pinned' section in the sidebar with its own divider
-      header
-    - Honorific Glow outline now renders when the title carries a
-      Glow colour. Opt-in via Settings → Integrations → 'Render glow
-      outlines (Honorific)' (default off, dodges the per-frame
-      DrawList overhead on low-end hardware). Gradient (Color3 /
-      GradientColourSet / Wave / Pulse) is parsed but rendered
-      statically — a later cycle will port the full animation
-    - Sidebar width is now configurable in Theme & Layout (range
-      44–160 px). Default stays icon-only; widen to fit section
-      headers like 'Active Tells (3)' without truncation
-    - Settings Save no longer pops the chat input back to /tell with
-      a pinned partner — Configuration.UpdateFrom now preserves the
-      runtime CurrentChannel across the persistent-tab merge, and
-      TabSwitched deep-clones the seeded channel instead of sharing
-      the previous tab's UsedChannel
-    - Util/ImGuiUtil.cs DrawArrows IconButton id now uses
-      (id + 1).ToString() instead of the operator-precedence quirk
-      id + 1.ToString() — generated IDs stay numerically stable
-    - Internal: IPluginLogProxy indirection over Dalamud's IPluginLog
-      routes all ~91 Plugin.Log call sites through a testable proxy.
-      MessageStore.Migrate0 can now run in xUnit without loading
-      Dalamud.dll, closing the gap F12.1 left in v1.4.6
-    - Internal: TempTab counter switched from an Interlocked cached
-      field to a derived Tabs.Count(predicate) — pin-state transitions
-      are cold-path and don't need lock-free reads
-
-    Based on Chat 2 1.35.3 (upstream Infiziert90/ChatTwo, EUPL-1.2).
