Merge feature/v1.4.6 — Code Hygiene and Refactor

Crystal Nocturne (royal sapphire + electric magenta on obsidian, by
CRYSTALLITE) replaces Moonlit Bloom in the built-in roster. The same
chat-channel tinting convention applies: sapphire-blue identity on
party/team channels, accent-magenta on tells, and an alternating
mint/yellow/peach palette across the eight linkshell slots so each
LS stays individually distinguishable on the dark obsidian background.

Users who had Moonlit Bloom selected fall back to the default Hellion
Arctic on the first plugin load. A custom JSON copy of Moonlit Bloom
dropped into pluginConfigs/HellionChat/themes/ keeps working as a
user theme.

Plus a cosmetic re-sort of the registry: insertion order now drives a
deliberate Theme-Picker grid layout (3 columns) — blue family in row 1,
purple to magenta in row 2, green/warm/classic in row 3, Synthwave
Sunset alone in row 4 as a retro bonus.

+**Hellion Chat 1.4.4 — Threading- und IPC-Sicherheits-Politur**
+
+Fünfter Sub-Patch der v1.4.x Polish-Sweep-Serie. Threading-Annahmen werden explizit pro Methode dokumentiert, ein
+Hot-Path-Lock im Auto-Tell-Tab-Counter fällt weg, IPC-Cleanup wird sichtbar wenn er fehlschlägt und der Privacy-Filter
+spricht jetzt bei unbekannten ChatTypes.
+
+- **AutoTellTabsService Hot-Path-Lock entfernt.** `ActiveTempTabCount` hat bisher pro Render-Frame ein LINQ-Count unter
+  einem Lock gemacht. Jetzt läuft das über einen Interlocked-Counter der parallel zur Tabs-Liste mitgeführt wird,
+  inklusive Resync-Hook für den Snapshot-Restore-Pfad in `SaveConfig`. Plus Pure-Helper-Test-Mirror in der Build-Suite
+  damit die Atomicity-Semantik nicht versehentlich wegrefactored wird
+- **HonorificService selbst-dokumentierende Threading-Banner.** Statt eines Block-Comments am Klassen-Ende hat jede
+  IPC-Callback-Methode jetzt einen 1-Zeilen-Banner darüber, der den Thread-Kontext direkt am Call-Site benennt
+  (framework only, framework scheduled, any). Mehr Hilfe für künftige Reviews als ein abstraktes Threading-Kapitel
+- **Unsubscribe-Failure ist jetzt sichtbar.** `TryUnsubscribe` hat ein Honorific-Unsubscribe-Failure bisher als Debug
+  geloggt, was bei Standard-Loglevel verschluckt wurde. Eine geleakte Subscription kann den Service über Plugin-Reloads
+  hinweg leben lassen, also läuft der Log jetzt auf Warning
+- **AutoTranslate-Warmup blockiert den Plugin-Unload nicht mehr.** Der Cache-Warmup-Thread war ohne `IsBackground=true`
+  unterwegs, was den Unload um 100-300 ms verzögern konnte. Pattern-Match zu MessageManager und RetentionSweep (beide
+  seit v1.4.0)
+- **Privacy-Filter loggt unbekannte ChatTypes.** Wenn FFXIV durch einen Patch einen neuen ChatType einführt der weder in
+  der Whitelist noch in den Defaults steht, wird er bisher silent durch den Failsafe geleitet. Jetzt loggt der Filter
+  einmalig pro Runtime eine Warning mit dem Type und dem Failsafe-Wert. Dedup über ein NonSerialized-HashSet, also kein
+  Log-Spam
+- **Default-Flip für neue Installationen.** `PrivacyPersistUnknownChannels` startet bei neuen Configs jetzt auf `true`,
+  damit ein Patch-bedingt neuer ChatType nicht stillschweigend gedroppt wird bevor der User entscheiden kann. Bestehende
+  Configs behalten ihre Wahl, weil der Deserializer den Initializer überschreibt. Keine Migration, kein Schema-Bump
+
+Keine User-sichtbaren Funktions-Änderungen außer dem Default-Flip für neue Installationen. Settings, Themes, Tabs und
+das Privacy-Verhalten für Bestand bleiben unangetastet.

+**Hellion Chat 1.4.5 — UX und Robustheit**
+
+Sechster Sub-Patch der v1.4.x Polish-Sweep-Serie. Render-Fehler im Chat-Fenster werden jetzt sichtbar, der
+First-Run-Wizard hat eine explizite Cancel-Schaltfläche, der Eingabe-Verlauf bleibt nicht mehr über Plugin-Reloads
+hinweg liegen, und die Statusleiste klippt in schmalen Fenstern nicht mehr.
+
+- **Fehler-Benachrichtigung im Chat-Fenster.** Wenn ein Render-Fehler in `DrawChatLog` auftritt, zeigt das Plugin jetzt
+  eine einmalige Warning-Notification mit Verweis aufs `/xllog`, statt das Fenster stillschweigend leer zu lassen. Der
+  Stack-Trace selbst geht weiter via `Plugin.Log.Error` ins Logfile. De-Dup über Per-Session-Bool, damit ein
+  wiederkehrender Fehler die Notification-Stack nicht pro Frame neu vollkippt
+- **First-Run-Wizard trennt Accept und Close.** `OnClose` setzt nicht mehr stillschweigend `FirstRunCompleted=true`,
+  also lässt das X den Wizard schwebend zurück und er kommt beim nächsten Plugin-Reload wieder. Eine neue „Später —
+  Defaults behalten"-Schaltfläche im Footer ist der explizite Weg, ohne Profil-Auswahl rauszukommen. Strings bilingual
+  EN+DE plus Tooltip
+- **Eingabe-Verlauf wird beim Plugin-Reload geleert.** `InputHistoryService.Reset` hängt jetzt in `Plugin.DisposeAsync`
+  neben den anderen Pure-Memory-Cleanups, damit der statische Zustand aus der vorigen Session den nächsten Load nicht
+  mehr erbt
+- **Statusleiste klippt nicht mehr.** Der rechtsbündige Versions-Slot wird ausgeblendet wenn die Chat-Window-Breite
+  abzüglich Versions-Text unter 200 px fällt — vorher überlappte er die vier linken Slots. Ab ausreichender Breite
+  taucht der Slot wieder auf
+- **Intern:** `FontManager` fällt auf System-Font zurück wenn die eingebettete Hellion-Font-Resource fehlt
+  (Broken-csproj-Pfad, nie ein Produktions-Build), plus expliziter Session-Only-Invariant-Kommentar für Auto-Tell-Tabs
+  in `Plugin.cs:167-168` mit einem TempTabCounter-Init-Pin in der Build-Suite. Kein Schema-Bump, keine Migration

+Wartungs-Patch ohne User-sichtbare Änderungen. Saubere Code-Basis als Vorbereitung auf das v1.4.7-Backlog-Cleanup, plus zwei geerbte Bugfixes aus dem ChatTwo-Upstream `f35b7d3`.
+
+- **preflight.sh härter**: csharpier-Reflow-Check (Block E) und markdownlint (Block F) laufen jetzt im Pre-Push-Gate, statt erst beim Pre-Merge-Review aufzufallen.
+- **FontManager-Fallback robuster**: Atlas-Toolkit-Throws aus kaputten Font-Configs (IO, InvalidOperation, ArgumentException) fallen jetzt zuverlässig auf NotoSansCjkRegular, statt den Atlas-Build mitzureißen. Der Exception-Typ wird im Log mitgegeben für die Diagnose.
+- **URL-Validation beim Plugin-Load**: BrandingLinks (5 URLs) und IntegrationLinks (2 URLs) werden via `[ModuleInitializer]` geprüft. Ein Tippfehler bei einer künftigen URL-Rotation wirft jetzt sofort beim Plugin-Load, statt still beim Klick zu scheitern.
+- **Cherry-Pick aus ChatTwo `f35b7d3`** — Memory-Leak in `Chat.SetChannel`: der native `Utf8String` wird jetzt auch dann freigegeben, wenn der Linkshell-Check den Channel ablehnt (vorher gefangen im early-return).
+- **Cherry-Pick aus ChatTwo `f35b7d3`** — `Tab.Clone()` Deep-cloned jetzt `UsedChannel` und `TellTarget`. Vorher Reference-Share-Bug: PopOut- und Temp-Tabs mutierten sich gegenseitig.
+- **Aktive-Tab-Underline pixel-perfect bei DPI-Scaling**: Die Underline-Pill skaliert jetzt mit `ImGuiHelpers.GlobalScale` und rundet die DrawList-Koordinaten auf physische Pixel. Kein Sub-Pixel-Blur mehr auf 125/150%-Setups.
+- **IconButton-Width-Fix**: der manuelle `width - 2 * CellPadding.X`-Subtract verlor den HUD-Scale (Padding skaliert, der raw int nicht). Gemessene Breite läuft jetzt unverändert durch.
+- **Test-Isolation für MessageStore**: `Dalamud.Utility.Util`-Surface (IsWine, OpenLink) läuft jetzt durch eine `IPlatformUtil`-Indirektion. MessageStores `IsWine`-Probe ist isoliert testbar in der Build-Suite. Plus: HellionStyle-ChildBgAlpha als Pure-Helper extrahiert, Plugin.SaveConfig kopiert nur Session-Tabs statt der ganzen Tab-Liste, SettingsOverview cached den DrawList einmal pro Frame.
+- **Built-in-Theme-Roster**: Crystal Nocturne (Royal Sapphire + Electric Magenta auf Obsidian, von CRYSTALLITE) ersetzt Moonlit Bloom. User mit Moonlit Bloom als aktivem Theme fallen beim ersten Plugin-Load auf Hellion Arctic zurück.

+    **v1.4.6 — Code Hygiene and Refactor (2026-05-12)**
+
+    Maintenance patch. No user-visible behaviour changes; tightens the
+    development feedback loop, fixes two upstream-inherited bugs, and
+    prepares the code for the v1.4.7 backlog cleanup.
+
+    - preflight.sh gains a csharpier reflow check and a markdownlint
+      pass so style drift and markdown violations are caught at the
+      pre-push gate
+    - FontManager fallback catches the full set of atlas-toolkit
+      throws (IO, InvalidOperation, ArgumentException) — a corrupt
+      font config no longer takes down the whole atlas build
+    - BrandingLinks and IntegrationLinks URLs validated on plugin
+      load — a typo in a future URL rotation now throws at startup
+    - Cherry-picked from ChatTwo upstream f35b7d3: Chat.SetChannel
+      no longer leaks the native Utf8String when the linkshell check
+      rejects the channel
+    - Cherry-picked from ChatTwo upstream f35b7d3: Tab.Clone now
+      deep-clones UsedChannel and TellTarget — PopOut and Temp tabs
+      no longer mutate each other's channel state
+    - Active-tab underline scales with DPI and rounds to physical
+      pixels for crisp rendering above 100% scaling
+    - IconButton width parameter no longer subtracts HUD-scaled
+      padding from a raw int (measured width passes through verbatim)
+    - Internal: HellionStyle ChildBgAlpha extracted to a testable
+      helper; Plugin.SaveConfig clones only the temp tabs;
+      SettingsOverview caches the draw-list per frame;
+      Dalamud.Utility.Util surface routed through an IPlatformUtil
+      indirection (MessageStore IsWine probe is now testable in
+      isolation)
+    - Built-in themes: Crystal Nocturne (sapphire and electric
+      magenta over obsidian, by CRYSTALLITE) replaces Moonlit Bloom.
+      Users with Moonlit Bloom selected fall back to Hellion Arctic
+      on first load
+
+    Based on Chat 2 1.35.3 (upstream Infiziert90/ChatTwo, EUPL-1.2).
+
+    ---
+
+    **v1.4.5 — UX and Robustness (2026-05-12)**
+
+    Sixth sub-patch of the v1.4.x polish-sweep series. Chat-log draw
+    failures surface as a notification, the first-run wizard has an
+    explicit "Later" option, the input history clears on plugin reload,
+    and the status bar version slot stops clipping in narrow windows.
+
+    - Chat window draw errors now show a one-shot notification instead
+      of failing silently — stack trace stays in /xllog
+    - First-run wizard: explicit "Later — keep defaults" button.
+      Closing the X no longer silently accepts the defaults; the wizard
+      reopens on the next plugin load if nothing was picked
+    - InputHistoryService clears on plugin dispose so the previous
+      session's typed commands don't bleed into the next load
+    - Status bar hides the version slot when the chat window is too
+      narrow to fit all five slots without overlap
+    - Internal: explicit session-only Auto-Tell-Tab invariant in
+      Plugin.cs plus a pinning test in the Build-Suite
+    - Internal: FontManager falls back to the system font if the
+      embedded Hellion font resource is missing — logs a Warning
+
+    ---
+
+    **v1.4.4 — Threading and IPC safety polish (2026-05-12)**
+
+    Fifth sub-patch of the v1.4.x polish-sweep series. Threading
+    assumptions are documented per-method, a hot-path lock falls
+    away, and the privacy filter speaks up when an unknown ChatType
+    shows up.
+
+    - AutoTellTabs hot-path getter uses an Interlocked counter
+      instead of taking the lock on every read
+    - Honorific integration: per-method threading banners, plus
+      Warning-level log on unsubscribe failure
+    - AutoTranslate warmup thread marked IsBackground so plugin
+      unload doesn't wait for it
+    - PrivacyFilter logs once per unknown ChatType so a future
+      patch's added channel doesn't drop off the radar
+    - New installs persist unknown channels by default; existing
+      configs keep their explicit choice

 ## Project Status
 
-**Version 1.4.3** — Plugin-load async init plus repo cutover: the plugin has been migrated to Dalamud's
-`IAsyncDalamudPlugin` API. The constructor now handles only bootstrap essentials (config load, language init, conflict
-detection); migrations, service allocations, window construction, and hook subscriptions move into `LoadAsync`, allowing
-Dalamud to keep the UI responsive during heavy lifting. A schema gate replaces the v9 → v16 migration chain; configs at
-schema v16+ load directly, older configs trigger an "install v1.4.2 first" error message. Custom repo URL migrated to
-`gitea.hellion-forge.cloud`; the GitHub repo remains as a frozen v1.4.2 snapshot. Plugin load time is ~3.7 s median (5
-reloads), comparable to v1.4.2 — the async migration is the foundation for v1.4.4 lazy-init optimizations, not a direct
-user-facing win. Fourth sub-patch of the v1.4.x polish sweep series (as of 2026-05-08).
+**Version 1.4.6** — Maintenance patch. No user-visible behaviour changes; tightens the development feedback loop and

+`ArgumentException` on top of the IO triad, so a corrupted font config no longer takes down the atlas build.

+## Hellion Chat 1.4.6 — Code Hygiene and Refactor (2026-05-12)
+
+Maintenance patch. No user-visible behaviour changes; tightens the development feedback loop, fixes two
+upstream-inherited bugs from ChatTwo `f35b7d3`, and prepares the code for the v1.4.7 backlog cleanup.
+
+- `scripts/preflight.sh` gains Block E (`dotnet csharpier check`) and Block F (`markdownlint-cli2`) so reflow drift and
+  markdown violations are caught at the pre-push gate. `.markdownlint.json` adds `MD024 siblings_only` and disables
+  `MD036` so the bilingual forge-post bold-emphasis headings pass linting; the `.claude/` directory is excluded from the
+  scan
+- `FontManager.AddFontWithFallback` catch-filter now covers `InvalidOperationException` and `ArgumentException` on top
+  of the existing IO triad. The warning log carries the exception type name, so the diagnostic path knows which class
+  of atlas-toolkit throw triggered the NotoSansCjkRegular fallback
+- `BrandingLinks` (5 URLs) and `Integrations/IntegrationLinks` (2 URLs) validate themselves on first module load via
+  `[ModuleInitializer]` + a shared `UrlValidation.ValidateAll` helper. A malformed URL now throws
+  `InvalidOperationException` at plugin load with the source class and the broken URL in the message
+- Cherry-picked from ChatTwo upstream `f35b7d3`: `Chat.SetChannel` no longer leaks the native `Utf8String` when the
+  linkshell check rejects the channel. The validity check is now wrapped around the `ChangeChatChannel` call instead of
+  short-circuiting before `Dtor`. `ValidAnyLinkshell` is renamed to `IsChannelOrExistingLinkshell` and the
+  `ChatLogWindow` call-site follows the rename
+- Cherry-picked from ChatTwo upstream `f35b7d3`: `Tab.Clone` now deep-clones `UsedChannel` and `TellTarget`. The old
+  `CurrentChannel = CurrentChannel` was a reference copy, so PopOut and Temp tabs mutated each other's channel state
+  (incl. tell target). `TellTarget.From(t)` static factory is replaced with an instance `Clone()`; `UsedChannel.Clone()`
+  is new and runs deep-clone on both TellTarget references
+- `ChatLogWindow` active-tab underline pill now scales with `ImGuiHelpers.GlobalScale` and rounds its DrawList
+  coordinates to physical pixels via `MathF.Round`, so the 2 px line stays crisp on 125 % and 150 % DPI setups instead
+  of bleeding into a sub-pixel blur
+- `ImGuiUtil.IconButton` width parameter no longer subtracts HUD-scaled `CellPadding.X * 2` from the raw `int` width.
+  `ImGui.Button` handles its own frame padding internally, so the measured `buttonWidth` now passes through verbatim
+  (inspired-by upstream `f35b7d3`, but our two call-sites need the parameter, so the param itself stays)
+- Internal: `HellionStyle` ChildBgAlpha threshold logic extracted to `HellionStyleHelpers.ResolveChildBgAlpha` with a
+  build-suite mirror test that pins the 0.999f cutoff. `Plugin.SaveConfig` clones only the temp-tab subset in the
+  pre-serialization snapshot instead of the full tab list. `SettingsOverview` caches `ImGui.GetWindowDrawList()` once
+  per frame and passes the pointer down to `DrawCard`
+- Internal: `Dalamud.Utility.Util` static surface (`IsWine`, `OpenLink`) routed through a new `IPlatformUtil`
+  indirection. `MessageStore`'s `IsWine` probe is now reachable from the xUnit AppDomain via a `FakePlatformUtil`
+  fixture (full isolated MessageStore construction still pending — `Plugin.Log.Information` in `Migrate0` is a separate
+  Dalamud-static surface, slated for v1.4.7)
+- Built-in themes: Crystal Nocturne (royal sapphire and electric magenta over obsidian, by CRYSTALLITE) replaces
+  Moonlit Bloom in the built-in roster. Users who had Moonlit Bloom selected fall back to the default Hellion Arctic
+  on the first plugin load; an existing custom JSON copy of Moonlit Bloom under `pluginConfigs/HellionChat/themes/`
+  keeps working unchanged

+## Hellion Chat 1.4.5 — UX and Robustness (2026-05-12)
+
+Sixth sub-patch of the v1.4.x polish-sweep series. User-visible robustness fixes plus two doc/test polish items from the
+audit backlog. No schema bump, no migration.
+
+- `ChatLogWindow.Draw` now surfaces a one-shot warning notification when the draw path throws. The stack trace still
+  goes to `/xllog` via `Plugin.Log.Error`; the notification is suppressed for the rest of the plugin session so a
+  recurring failure can't spam the notification stack frame-by-frame. Pattern-match to the existing `Plugin.cs:505-516`
+  migration-blocker notification
+- `FirstRunWizard` splits accept from close. `OnClose` no longer silently sets `FirstRunCompleted`, so closing the X
+  leaves the wizard pending and it reopens on the next plugin load. A new footer "Later — keep defaults" button is the
+  explicit path to dismiss without picking a profile. Bilingual strings (EN + DE) plus a tooltip
+- `InputHistoryService.Reset` is wired into `Plugin.DisposeAsync` alongside the existing pure-memory cleanups. Static
+  state used to survive a plugin reload — the next load now starts with an empty history
+- `FontManager.GetHellionFontBytes` becomes `TryGetHellionFontBytes` with a nullable return. On miss (broken csproj,
+  hand-rolled dev build) the caller falls back to the system-font path that `UseHellionFont=false` already uses, plus a
+  `Plugin.Log.Warning`. The whole UiBuilder no longer throws if the embedded font resource is absent
+- `Plugin.cs:167-168` gets a 4-line reasoning comment around the session-only `RemoveAll(IsTempTab)`: tells are usually
+  privacy-filtered, resurrecting an empty crashed-session tab would trigger DB reconstruction on the next load.
+  `TempTabCounter.InitFromList` mirrors the post-strip semantic in the Build-Suite with a pinning test
+- `StatusBar.cs` drops the version slot when the chat window's content width minus the version text is below 200 px. The
+  right-aligned version used to clip into the four left-side slots in narrow windows

+
+## Hellion Chat 1.4.4 — Threading and IPC Safety Polish (2026-05-12)
+
+Fifth sub-patch of the v1.4.x polish-sweep series. Threading assumptions are documented per-method, a hot-path lock
+falls away in `AutoTellTabsService`, IPC-cleanup failures become visible, and the privacy filter now speaks up when an
+unknown ChatType shows up.
+
+- `AutoTellTabsService.ActiveTempTabCount` switches from a lock-protected LINQ `Count` to an `Interlocked` counter kept
+  in sync with `Config.Tabs` from inside the existing mutation paths. `Initialize()` seeds the counter from the
+  persisted Tabs list, and `SaveConfig`'s snapshot-restore path calls a new `ResyncTempTabCounter()` so the mid-step
+  `RemoveAll` doesn't leave the counter drifting. Pure-helper test mirror lives in the Build-Suite repo
+- `HonorificService` per-method threading banners replace the block comment at the bottom of the file. Each IPC callback
+  (`TryInitialPull`, `OnTitleChanged`, `OnReady`, `OnDisposing`, `TryUnsubscribe`) and the `CurrentTitle` field carry a
+  one-line `// Thread:` annotation so the framework-thread invariant is visible at the call site
+- `TryUnsubscribe` log-level upgraded from `Debug` to `Warning`. A silent unsubscribe failure leaks a live subscription
+  across plugin reloads, which is exactly the kind of issue that should not be at Debug
+- `AutoTranslate.PreloadCache` thread now has `IsBackground = true` and a thread name. Without `IsBackground` the warmup
+  blocks plugin unload (typically 100-300 ms). Pattern-match to `MessageManager` (F6.1) and `Plugin.RetentionSweep`
+  (F9.3), both since v1.4.0
+- `Configuration.IsAllowedForStorage` adds a one-line `Plugin.Log.Warning` for the first occurrence of any ChatType that
+  isn't in `PrivacyPersistChannels`. Dedup via a `NonSerialized` `HashSet<ChatType>`, so the warning fires once per
+  runtime — not once per frame, not once per install. Failsafe routing through `PrivacyPersistUnknownChannels` is
+  unchanged
+- `PrivacyPersistUnknownChannels` field default flipped from `false` to `true` for new installs via a constant in
+  `PrivacyDefaults`. Existing configs keep their explicit choice — the deserializer overrides the initializer. No schema
+  bump, no migration, no first-run banner
