JonKazama-Hellion 8db3eca46c chore(fontmanager): drop unused Lodestone font download
The FontManager constructor downloaded FFXIV_Lodestone_SSF.ttf from
img.finalfantasyxiv.com on first start (or read it from a local
cache) into a GameSymFont byte array. Both historical readers of
that field are gone:

- BuildFonts() used to feed the bytes into AddFontFromMemory; that
  path was replaced by the Dalamud-provided AddGameSymbol helper.
- The upstream webinterface server wrote the bytes through a
  BinaryWriter to serve them to the Svelte frontend; the entire
  webinterface was intentionally removed in HellionChat.

With no live consumer left, the field, the constructor block, the
HttpClient call and the disk cache are all dead code. Removing them:

- eliminates the synchronous HTTP request on the plugin-load thread
  (no more multi-second startup hang on slow networks)
- closes the implicit "no timeout, no size guard" exposure on that
  request
- removes one outbound network endpoint (Square Enix Lodestone CDN)
  from the privacy footprint

PRIVACY.md and THIRD_PARTY_NOTICES.md updated to reflect that
HellionChat now talks to BetterTTV only (opt-out via setting). Cached
TTF files left over from earlier versions stay in pluginConfigs/
HellionChat/ until a user removes them; they are simply no longer
read.

Build: 0 warnings, 0 errors. No behavioural change for users — symbol
glyphs (job icons, item glyphs, status effects) keep rendering through
Dalamud's built-in symbol font.

Third-party notices

HellionChat ships and depends on a number of third-party components. This document lists them, their licences and which of them touch the network. It is the inventory referenced by PRIVACY.md.

Last reviewed: 2026-05-05 (HellionChat v1.0.3).


Direct NuGet dependencies

Pinned in HellionChat/HellionChat.csproj. Versions reflect the v1.0.3 build.

Package Version Licence Network Purpose
MessagePack 3.1.4 MIT no Binary serialisation for the SQLite message store.
Microsoft.Data.Sqlite 10.0.7 MIT no Local SQLite access for the message database.
morelinq 4.4.0 Apache-2.0 no LINQ helper extensions.
Pidgin 3.5.1 MIT no Parser combinator library used for chat-input parsing. CIString Unicode fix relevant for non-ASCII channel/tab names.
SixLabors.ImageSharp 3.1.12 Six Labors Split License 1.0 (OSI-approved; free for open-source / non-commercial use, commercial licence required for closed-source commercial use) no Image decoding for cached emotes.
SQLitePCLRaw.lib.e_sqlite3 3.50.3 MIT no Native SQLite binary, explicitly pinned to override the transitive default for CVE-2025-6965 (memory corruption from aggregate-term overflow) and CVE-2025-7709.

Six Labors note: HellionChat is an EUPL-1.2-licensed open-source project distributed at no cost. Use of ImageSharp 3.x under the Six Labors Split License 1.0 is permitted on that basis. Anyone forking HellionChat for closed-source or commercial redistribution should review the Six Labors licence terms and obtain a commercial licence if required.

SDK and tooling

Bundled assets

Asset Licence Source

Upstream code

HellionChat is a fork of Chat 2 by Infiziert90 (Infi) and Anna Clemens, also licensed under EUPL-1.2. The bulk of the code, including the message store architecture, the channel logic, the hook system and the ImGui chat window, originates from upstream. See ../NOTICE.md and UPSTREAM_SYNC.md for the attribution and the cherry-pick policy.


Components that touch the network

Of everything listed above, none of the bundled or NuGet components opens network connections on their own. All outbound traffic is initiated explicitly by HellionChat's own source files and is documented in PRIVACY.md under "Outbound network calls":

  • HellionChat/EmoteCache.cs → BetterTTV API + CDN (opt-out via setting)

The earlier Square Enix Lodestone font download (FontManager.cs) was removed in v1.0.4 — it was a leftover from upstream's removed webinterface feature and was no longer consumed.


Verifying this list

To regenerate the dependency inventory after a version bump:

dotnet list HellionChat.sln package --include-transitive

The "direct NuGet dependencies" table above only lists direct references. Transitive dependencies pulled in by Dalamud SDK or by the listed packages are covered by the SDK / package licences and documented by their respective maintainers.

To re-audit the network-call inventory:

grep -rn -E "HttpClient|HttpRequest|new Uri\(|https?://" \
  --include="*.cs" HellionChat/

Any new hit that is not a click-through (Util.OpenLink) or a payload-parsing call must be added to PRIVACY.md before release.
