flamenetmessenger.com declares its colours as CSS custom properties, so they
were there to be read rather than guessed:
--bg: #0a0e1a --panel: #121a2e --border: #1f2b45
--ink: #e8edf7 --muted: #9aa7c2
--flame: #ff5a1f --blue: #3b6fff --accent: #2dd4a7
⚠️ The site is dark and the apps are light, so only the accents transfer
literally. --ink and --muted are light-on-dark values that would be invisible
on a light ground; the neutrals here are the same navy family resolved for
light instead. Dark mode DOES use the site's real --bg and --panel.
The apps had been warm — ember on parchment. They are now the site's flame on
a cool navy-tinted ground, with the site's blue and teal available for
informational and success states rather than a second invented accent.
⚠️ Two flames, on purpose. White on #ff5a1f is about 3.1:1 — acceptable for a
bold button label under AA Large and not acceptable for small text. Small text
and links take a darkened #c4400f, which clears 5:1 on white. An accent used
uniformly is how it quietly becomes unreadable.
`Palette.Parchment` is now `Palette.Mist`: it is a cool near-white and the old
name described a colour that no longer exists here.
Also fixes the contacts card reserving a slab of empty white. BuddyList's
LazyColumn carried weight(1f), which always expands to whatever height it is
offered — so bounding the CARD just moved the problem, and one contact still
reserved 340dp. The list now caps itself with heightIn and the card sizes to
its content, scrolling only once the list is genuinely long.

Flamenet Messenger — Android
Nothing here is an app yet. This is the engine, and it is deliberately first.
An Android client needs the protocol implemented a third time. That third
implementation is the one that finds the places where the specification says
less than the two existing engines quietly agreed on — but only if it is
written against the spec and the published vectors rather than against a
reading of our own Swift and JavaScript. So the engine comes first, it is a
plain Kotlin/JVM library with no Android in it at all, and it is held to
engine/test/vectors/protocol-v1.json — the same file the other two engines
are checked against, read from that one location rather than copied here.
./gradlew :engine:test
No Android SDK, no emulator, no device. It runs anywhere a JVM does, which is also what lets it run in CI on Linux.
What the engine covers today
| Area | Spec | State |
|---|---|---|
| Safety numbers | §7 | Done — fingerprints and conversation ordering match the published vectors |
| Key transparency verification | §19 | Done — RFC 6962 leaf/node hashing, unbalanced split, bottom-up audit paths |
| Byte helpers | — | Unsigned comparison, constant-time equality |
What it does not cover
Listed rather than left to be discovered, because a table of green ticks with the hard parts quietly missing is worse than no table:
| Area | Spec | State |
|---|---|---|
| X25519 / Ed25519 | §3 | Not started — needs a provider that works on both JVM and Android |
| X3DH key agreement | §4 | Not started |
| Double Ratchet | §6 | Not started |
| Sealed sender | §12 | Not started |
| ML-KEM-768 hybrid | §11 | Not started |
| ML-DSA-65 identities | §20 | Not started |
| Relay client | §8 | Not started |
| The app itself | — | Not started |
Until those exist, Android is honestly marked "not started" on the website, and a conversation gets the protocol's guarantees only when both ends are iOS.
Why the vectors matter more than the code
Two implementations that agree may both be wrong in the same way, especially when one was written while reading the other. The audit-path ordering in §19 is the worked example: a top-down reading of a bottom-up path produces the correct root for every left-spine index, so it passes any test that only checks index 0. The vector file pins a right-descending index for that reason, and the Kotlin tests assert both that the published path verifies and that the same path reversed does not.
If this engine ever disagrees with the file, the interesting question is which of the three is wrong — not this one by default.
