## Yahoo Messenger DAT format references

The Yahoo reader research cited these projects when support was introduced in
commit `6bc41f3`. The current implementation in `src/parsers.js` was compared
with their publicly available parser sources during this review.

- **Yammy — Yahoo Messenger Archives Decoder**, by Pravin Paratey.
  The [project page](https://sourceforge.net/projects/yammy/) lists GPLv2.
  The [Decoder.cs source header](https://svn.code.sf.net/p/yammy/code/trunk/src/Decoder.cs)
  identifies copyright 2005–2007 Pravin Paratey and permits GPL version 2 or later
  (`GPL-2.0-or-later`). Its parser documents the record fields, repeating-account
  XOR and standard profile/message paths used in the format research.
- **YIM Archive Viewer**, by hirakujira.
  The [repository](https://github.com/hirakujira/YIM-Archive-Viewer) and its
  [parser](https://github.com/hirakujira/YIM-Archive-Viewer/blob/master/parser.js)
  also describe the DAT records, XOR and UTF-8/Big5 decoding. No explicit license
  file, license declaration in the reviewed README/parser, or GitHub-detected
  license was found on the review date. Do not describe this reference as MIT
  or assume its code is licensed for reuse merely because it is public.

Neither upstream application is bundled, imported or loaded as a runtime
dependency. The current reader has its own integration, validation, scoring,
message/date/index output and Worker pipeline. This inventory and source
comparison do not establish the development history or legal independence of
every expression in the implementation. Credits alone do not resolve any
licensing obligations if upstream code has been adapted.

## Format icons

- `assets/icons/ICQ.png`, `assets/icons/msn.png` and `assets/icons/mirc.png` are
  actively displayed in file rows, platform controls, tabs and chat headers.
  They were present in the initial repository commit. The repository contains
  no documented original download source or redistribution grant for these
  images. Their artwork must not be described as original Log Traveler artwork
  or automatically covered by its MIT license; provenance remains unverified.
- Yahoo's purple `Y!` speech-bubble indicator is drawn directly in
  `src/application/format-ui.js`, not loaded from an external Yahoo image.
  It appears in Yahoo file rows, platform controls, tabs and the chat header.
  Yahoo Messenger's name and identifying marks remain associated with their
  respective owners; this drawing is not an endorsement or permission grant.
- The former alternative SVG drawings of the three PNG platform icons have
  been removed. A generic document symbol handles image-loading failures.

## Bundled components

  retained in [assets/flags/countries/LICENSE](assets/flags/countries/LICENSE),
  with provenance in [SOURCE.md](assets/flags/countries/SOURCE.md).
- MSN emoticon artwork has a separate project-maintained provenance statement
  in [assets/emoticons/msn/SOURCE.md](assets/emoticons/msn/SOURCE.md).
