**Version 1.5.3** — Privacy-first chat plugin for FINAL FANTASY XIV / Dalamud, built on
[Chat 2](https://github.com/Infiziert90/ChatTwo) (EUPL-1.2).

Hellion Chat is a privacy-first plugin built on the Chat 2 foundation. The majority of the engine
comes from Chat 2 (message store, channel logic, hook system), and most keyboard shortcuts continue
to work as you'd expect. What changes: stricter privacy defaults out of the box, custom slash
commands under `/hellionchat`, no web interface, and as of v1.1.0, a theme engine as a step toward a
distinct UI look and feel.

The data-handling focus is on GDPR/EU, US, and JP regulations, as far as practically applicable for
a chat plugin: per-channel retention periods, granular filters, and self-service data export. A full
breakdown is available in [`PRIVACY.md`](PRIVACY.md).

This is a standalone repository, licensed under EUPL-1.2. With v1.0.0 the standalone cut is
complete: own namespace `HellionChat.*`, own IPC channels, own source tree structure. Distribution
via custom repo. Active upstream sync ended with the v1.4.x cycle: Chat 2 is undergoing a
fundamental rework and cherry-picks are no longer portable. From here, Hellion Chat continues as an
independent codebase — background and attribution in
[`docs/UPSTREAM_SYNC.md`](docs/UPSTREAM_SYNC.md).

## Acknowledgements

Hellion Chat is built on [Chat 2](https://github.com/Infiziert90/ChatTwo) by
**[Infiziert90 (Infi)](https://github.com/Infiziert90)** and
**[Anna](https://github.com/anna-is-cute)**, who maintained the plugin for years before I ever saw
the source code. The entire core architecture, the message store, the channel logic, the hook
system, and much more all come from them. If Hellion Chat helps you, the credit for that belongs in
large part to Infi and Anna. A full acknowledgement is in [NOTICE.md](NOTICE.md).

## Features

### Privacy / Compliance

- **Channel whitelist** for database persistence with privacy-first defaults. Out of the box, only
  your own conversations are stored (tells, party, FC, linkshells, cross-world linkshells, alliance,
  ExtraChat). Public chat, NPC dialogue, system spam, and battle logs are discarded at the storage
  layer.
- **Per-channel retention periods** with a daily background cleanup. Tells: 365 days, own
  conversation channels: 90 days, global default: 30 days. The default is OFF — the plugin deletes
  nothing without explicit consent.
- **Retroactive cleanup** with preview and Ctrl+Shift confirmation. Applies the current whitelist to
  an existing database, runs in the background, and calls VACUUM afterward.
- **Export** to Markdown, JSON, or CSV via the Dalamud file dialog (GDPR Art. 15 right of access).
  Filter by channel, date range, or sender substring.
- **Full privacy overview** in [`PRIVACY.md`](PRIVACY.md) and third-party components in
  [`docs/THIRD_PARTY_NOTICES.md`](docs/THIRD_PARTY_NOTICES.md): what is stored, which two outbound
  calls exist (BetterTTV opt-out, Square Enix Lodestone font), an explicit no-telemetry statement,
  and the mapping of GDPR rights (Art. 15/17/18/20/21) to concrete plugin functions.

### Onboarding

- **First-run wizard** with three profiles (Privacy-First, Relaxed, Full History) and a GDPR notice
  for the "Full History" option.
- **Configuration migration** seeds privacy defaults for existing users and shows a notification on
  the first plugin start after an update. With v1.0.0, users on config version 12 or older also
  receive a one-time tab layout reset; the old tab configuration is backed up as
  `pluginConfigs/HellionChat.json.pre-v13-backup`.
- **Layout migration from Chat 2** moves configuration and database to `pluginConfigs/HellionChat/`
  without data loss. Handles locked files gracefully (warns the user if Chat 2 is still loaded).
- **Migrate3 recovery** heals partially migrated databases from old Chat 2 installations.

### Look & Feel

- **Bilingual UI** (English and German) with live language switching. Hellion-specific strings are
  in `HellionStrings.<lang>.resx`.
- **Hellion HUD theme** with cyan-teal accents, slate-violet tabs, and amber highlights for active
  states.
- **Chat color presets** (v0.6.0) with seven built-in bundles in Settings → Appearance → Chat
  Colors: Classic (Chat 2 default), High Contrast, Pastel, Dark Mode Tuned, Hellion (brand), plus
  bonus moods Night Blue and Indigo Violet. One-click apply, battle channels remain untouched.
- **Window opacity slider** for combat-friendly transparency.
- **Bundled UI font** (Inter Light, OFL-1.1) as an optional default instead of the system font.
- **Hellion logo** bundled in the plugin and displayed in the Dalamud plugin list.

#### Custom Themes (v1.1.0)

HellionChat ships a theme engine with ten built-in themes (Hellion Arctic, Hellion Spectrum, Chat 2
Classic, Event Horizon, Crystal Nocturne, Mint Grove, Night Blue, Indigo Violet, Forge Merchantman,
Synthwave Sunset) and a JSON-based authoring format for custom themes. Schema and step-by-step guide
in [`docs/THEME-AUTHORING.md`](docs/THEME-AUTHORING.md). Hellion Spectrum is
Deuteranopia/Protanopia-safe (red-green color blindness) based on the Wong/Okabe-Ito palette.

#### Plugin Integrations (v1.3.0)

- **Honorific custom titles in the chat header.** When the Honorific plugin is active and a custom
  title is set, it is displayed in the chat header above the message log. Auto-detect with silent
  fallback: without Honorific the slot is invisible. Toggle in Settings → Integrations → Honorific.
  First cycle of a multi-stage plugin integration roadmap (context menu, NotificationMaster, RP
  status, ExtraChat, and XIVIM to follow).

### Pop-Out Convenience (v0.6.0)

- **Input bar in pop-out windows** as a global opt-in in Settings → Windows → Window Frame. When
  active, every pop-out window has a compact input at the bottom with a channel-colored icon button
  and text field. No more switching back to the main window for a quick reply.
- **Per-pop-out independent text buffer and history cursor.** Changing channels in a pop-out works
  globally like in the main window (FFXIV channel API), but half-typed input doesn't collide between
  the main window and pop-outs.
- **Shared input history** across all windows via singleton service. Up/Down arrow keys navigate the
  same list of the last 30 entries everywhere.

### Stability

- BetterTTV cache crash fix (null key handling).
- Font atlas build fallback for missing system fonts.
- Defensive wrapping of all migration operations.

### What's missing compared to Chat 2

The web interface was removed in Hellion Chat 0.2.0. It serves a different use case than the focus
of this fork — remote access to chat from a second device — which conflicts directly with the
privacy-first premise: a chat plugin that starts a local HTTP server is too large an attack surface
for my threat model. So it's gone.

If you want the full Chat 2 feature set, the upstream plugin serves you better. Hellion Chat is
deliberately the slimmer fork.

### Rules

- **Code namespace is `HellionChat.*`.** Fully consolidated onto the plugin name since v1.0.0 — no
  remaining `ChatTwo.*` anywhere in the source tree.
- **AssemblyName is `HellionChat`.** Own slot in `pluginConfigs/`, own file manifest, no shared
  state with Chat 2. Parallel-loading upstream Chat 2 is actively blocked on startup (bilingual
  conflict message).
- **IPC channels are `HellionChat.*`.** Six channels for third-party plugin integration (`Register`,
  `Available`, `Unregister`, `Invoke`, `GetChatInputState`, `ChatInputStateChanged`). Details in
  [`docs/IPC.md`](docs/IPC.md).
- **Hellion-specific strings in `HellionStrings.*.resx`**, strings carried over from Chat 2 in
  `Language.*.resx`. The original `Language.*.resx` structure is preserved because the existing
  translations from the upstream Crowdin community remain valuable.
- **No direct access to `Plugin.Interface.UiBuilder.FontAtlas`** outside of `FontManager`. Font
  fallback and the Hellion font are managed centrally.

## Database

SQLite, schema inherited from upstream Chat 2 (migration level v3). Hellion extensions live in
`Configuration` as fields, not in the DB schema:

| Column           | Type    | Description                  |
| ---------------- | ------- | ---------------------------- |
| Id               | BLOB    | Guid                         |
| Receiver         | INTEGER | Receiver ContentId           |
| ContentId        | INTEGER | Sender ContentId             |
| Date             | INTEGER | Unix timestamp (ms)          |
| ChatType         | INTEGER | XivChatType / LogKind        |
| SourceKind       | INTEGER | Player / NPC / Server / etc. |
| TargetKind       | INTEGER | Player / NPC / Server / etc. |
| Sender           | BLOB    | MessagePack `List<Chunk>`    |
| Content          | BLOB    | MessagePack `List<Chunk>`    |
| SenderSource     | BLOB    | MessagePack `SeString`       |
| ContentSource    | BLOB    | MessagePack `SeString`       |
| ExtraChatChannel | BLOB    | Guid                         |
| Deleted          | BOOLEAN | Soft-delete marker           |

Path: `pluginConfigs/HellionChat/chat-sqlite.db`. WAL mode, Synchronous=NORMAL.

## Installation

Hellion Chat is distributed via a Dalamud **custom repository**.

### Fresh install (no prior Chat 2)

1. Open Dalamud Settings (`/xlsettings`) → **Experimental**.
2. Add a new entry under **Custom Plugin Repositories**:

```text
    https://gitea.hellion-forge.cloud/JonKazama-Hellion/HellionChat/raw/branch/main/repo.json
```

3. **Save**, then go to `/xlplugins` → **All Plugins** → Refresh.
4. Hellion Chat appears in the list — install it like any other plugin.

### Migration from Chat 2 (with existing history)

Chat 2 and Hellion Chat share the database file until Hellion Chat moves it to its own path on first
start. Order matters:

1. **Disable Chat 2** in `/xlplugins` (do not uninstall, just disable).
2. **Fully close FFXIV** so SQLite releases the file lock. A plugin reload alone is not enough.
3. Restart the game.
4. Add the custom repo as described above.
5. Install Hellion Chat. On first start, the configuration file and the entire database directory
   are moved into the HellionChat layout.
6. **Verify** under Settings → Privacy → Refresh preview that the message count looks plausible.

### Troubleshooting

**Hellion Chat shows 0 messages, even though Chat 2 was active before:**

Migration was blocked by a locked file. Close the game and move the files manually:

Linux / XIVLauncher Core:

```bash
mv ~/.xlcore/pluginConfigs/ChatTwo/chat-sqlite.db \
   ~/.xlcore/pluginConfigs/HellionChat/chat-sqlite.db
[ -d ~/.xlcore/pluginConfigs/ChatTwo/EmoteCacheV1 ] && \
  mv ~/.xlcore/pluginConfigs/ChatTwo/EmoteCacheV1 \
     ~/.xlcore/pluginConfigs/HellionChat/
```

Windows / XIVLauncher:

```powershell
Move-Item "$env:AppData\XIVLauncher\pluginConfigs\ChatTwo\chat-sqlite.db" `
          "$env:AppData\XIVLauncher\pluginConfigs\HellionChat\chat-sqlite.db" -Force
```

Start the game, enable Hellion Chat, and your history is back.

### Updates

Updates appear automatically in the plugin list once a new `vX.Y.Z` tag with a GitHub Release is
published. No reinstall needed.

---

## Distribution

Hellion Chat is distributed via its own Dalamud custom repository (`repo.json` in the repo root).
Pushing a `vX.Y.Z` tag triggers the [`release.yml`](.github/workflows/release.yml) workflow, which
attaches the build output (`HellionChat/bin/Release/HellionChat/latest.zip`) along with the matching
changelog block from `HellionChat.yaml` to the GitHub Release. Manual recovery path if the
auto-trigger is missed: `gh workflow run release.yml -f tag=vX.Y.Z`.

An optional submission to the Dalamud main plugin repo (in addition to the custom repo) is on the
[roadmap](docs/ROADMAP.md).

## Project Status

**Version 1.5.3** — Localisation Wave + Bundled-Font Overhaul. Twenty-four selectable UI languages
(Catalan, Czech, Danish, Dutch, English, Finnish, French, German, Greek, Hungarian, Italian,
Japanese, Korean, Norsk bokmål, Polish, Portuguese (Brazil), Portuguese (Portugal), Romanian,
Russian, Spanish, Swedish, Turkish, Ukrainian, Simplified Chinese, Traditional Chinese); dropdown
sorts alphabetically by endonym, "None" pinned first. Non-native translations are AI-assisted and
flagged for community native-speaker review. The bundled UI font swaps from Exo 2 to **Inter
Light** (SIL OFL 1.1, 343 KB) for wider Latin Extended-A/B, Greek polytonic and Cyrillic Supplement
coverage. **NotoSansCjkRegular** joins as a third merge layer so Hangul and Simplified-Chinese
glyphs the FFXIV Japanese game font does not ship now render correctly. First-frame HITCH dropped
from ~74 ms (v1.5.2 baseline that held since v1.4.x) to a median of ~20 ms (5-reload sample
17.9-23.6 ms, Linux/Wine) as a side effect: the bundled-font path was silently falling back to the
FFXIV Axis game font for the entire v1.5.x series because of an early-return in `Plugin.cs:937`.
The fix routes `RegularFont` through draw whenever either `FontsEnabled` or `UseHellionFont` is on,
and lands the defer-pattern win v1.5.1 was reaching for. `ExtraGlyphRanges` auto-activates the
matching flag on language change; two new flags (`LatinExtended`, `Greek`) join the existing set.
A WarningText under the language dropdown notes that FFXIV's own chat input only fully supports
EN/DE/FR/JA — other languages may garble when typed in-game. Migration v17 stays.

---

### Project status (pre-v1.5.3, kept for context)

**Version 1.5.2** — First-Run Wizard Rework. The single-page wizard becomes a four-step
staged-commit flow (Welcome → Privacy → Power Settings → Done). The privacy picker becomes a 2×2
grid with a fourth profile "Roleplay" that extends Privacy-First with `Say` and both emote types
under a 30-/90-day retention window. A power-settings stage surfaces six previously-hidden
`Configuration` defaults in one place without introducing any new settings. The wizard window
shrinks to 720×480 default (was 900×560, MinimumSize 600×400) after smoke feedback and Step 1
keeps the fox banner in a folded TreeNode so the onboarding copy stays primary. Existing v1.5.1
users see the new flow once on first v1.5.2 boot via a new `WizardLastShownVersion` config marker.
Under the hood: a `WizardStateSmokeStep` joins `/xlperf`, the Build Suite gains twelve pure-helper
xUnit Facts pinning all four privacy profile sets and the new Roleplay retention overrides.
Migration v17 stays — `Configuration` only grows one optional string field.

---

### Project status (pre-v1.5.2, kept for context)

**Version 1.5.1** — FontAtlas Refactor and Hellion Forge Signature. The FontManager moves from the
inherited Chat 2 anti-pattern (null! fields + a separate BuildFonts method) to a hybrid model where
the game fonts and FontAwesome are init-only handles and only the user-configurable delegate fonts
stay mutable. All five handles register inside a single `IFontAtlas.SuppressAutoRebuild` block in
the ctor, so the font atlas builds once per plugin load instead of four to five times. FontAwesome
itself is now Dalamud's `UiBuilder.IconFontFixedWidthHandle` rather than a custom delegate slot.
Live font-setting changes go through `RebuildDelegateFonts()` and no longer require a plugin reload.
Plus an embedded Hellion Forge signature (drawn by Julia Moon) appears as a fox-head silhouette in
the `/xllog` bootstrap banner and a full fox in the First-Run Wizard and Settings → Information tab.

The Honorific full-gradient port that was originally scheduled for v1.5.1 was dropped: Honorific 3.2
exposes no IPC for the rendered gradient frame, and an in-plugin port of the colour palette was
declined. The integration stays at the v1.4.7 glow-only shape.

The 10× HITCH cut targeted from the v1.5.0 cross-plugin baseline (Lightless / XIVInstantMessenger
defer their font-atlas build to land at ~7 ms; Chat 2 + HellionChat were ~75 ms) did not land — the
cost lives in the UiBuilder first-frame render path, not in the atlas build. A first-frame render
investigation is reserved for a later cycle.

**Version 1.5.0** — DI Foundation and Service Refactor. Major architecture cycle: the plugin
bootstrap moves to a generic-host DI container (`Microsoft.Extensions.Hosting` +
`IServiceCollection`) modelled on Lightless Sync. All 18 instance-class services migrate from a
static `Plugin.LogProxy` locator to `Microsoft.Extensions.Logging.ILogger<T>` via constructor
injection, with a custom `DalamudLogger` bridging the framework over to Dalamud's `IPluginLog`. The
proxy stays for the eight buckets ctor-injection cannot reach (static helpers like `EmoteCache`,
Dalamud-reflected `Configuration`, the `Message` data class, and static methods inside `FontManager`
/ `GameFunctions`). Plugin.cs finishes the cycle at 1012 lines — virtually identical to the
pre-cycle 1013 — because the new Phase-1 host build and Plugin.X bridge wiring trade out exactly the
service and window allocations that left `LoadAsync`. Cross-plugin baseline confirms no performance
penalty vs Chat 2: HellionChat first-frame HITCH 77 ms median, Chat 2 74 ms. 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 item. One user-visible fix bundled in from upstream: pasting a
slash command into the chat input (Friend List "/tell" action, plugin-driven inserts) now replaces
the existing input instead of concatenating onto whatever the user was typing. Migration v17 stays
(no schema bump).

Hellion Chat is a standalone plugin, no longer a fork in the repository sense. Fully completed:

- Privacy filters (whitelist, retention, retroactive cleanup, export)
- First-run wizard with three profiles
- Plugin identity: own `HellionChat` slot, layout migration from Chat 2, Migrate3 recovery
- Bilingual UI (EN and DE) with live language switching
- Hellion theme, Hellion logo, bundled Inter Light font
- Custom repo pipeline with automated GitHub Release distribution
- Slash commands consolidated to the `/hellionchat` family
- Web interface removed (v0.2.0)
- Audit hardening (path traversal, retention race, DbViewer consistency)
- About tab in Hellion branding, localized EN and DE, with license and disclaimer
- AI disclosure documented (see [`docs/AI_DISCLOSURE.md`](docs/AI_DISCLOSURE.md))
- Standalone cut: namespace `HellionChat.*`, IPC channels `HellionChat.*`, source tree restructure,
  conflict detection against upstream Chat 2, SQLite CVE hardening (3.50.3)
- Theme engine with ten built-in themes plus JSON authoring format (engine v1.1.0, catalog extended
  in v1.2.3, including CVD-safe Hellion Spectrum; Synthwave Sunset in v1.4.1)
- ABGR cache on theme records: `HellionStyle.PushGlobal` reads pre-computed ABGR instead of
  converting RGBA→ABGR per slot per frame (v1.4.1, ~13% render-time recovery)

In progress: incremental modernization of UI look and feel beyond the theme engine. What's planned
next and what's on the long-term list is in [`docs/ROADMAP.md`](docs/ROADMAP.md). Concrete scheduled
items are also tracked in the
[Gitea issue tracker](https://gitea.hellion-forge.cloud/JonKazama-Hellion/HellionChat/issues) under
the `roadmap` label.

### On Release Cadence

Anyone looking at the repo for the first time will notice a lot of releases and a high commit count
in a short time. Both are deliberate. The full reasoning — four factors behind it — is in
[`docs/LEARNING-JOURNEY.md`](docs/LEARNING-JOURNEY.md), section "How I release this fast".
