The previous commit broke CI on main here, and the mechanism is worth recording.
Measured, by asking each cache for the path that failed in keystore-module
(the same class of path fails in every Rust-building repo):
logos-co.cachix.org 200 <- present
cache.nix.logos.co/public 404
cache.nix.logos.co/ci 404
cache.nixos.org 404
The failing path is a fixed-output fetch of a crates.io tarball
(crate-alloy-eip7928-0.3.4.tar.gz). With Cachix in the substituters CI never
performed that fetch -- it downloaded the finished path. Dropping Cachix
therefore did not merely cost cache hits: it made CI attempt the fetch for the
first time, and it fails there in ~7 minutes, taking cargo-vendor-dir and the
whole module with it.
The crate itself is healthy: that URL returns 20373 bytes hashing to
407510740da5..., exactly the expected outputHash. So this is not a yanked crate
or a stale hash -- it is an untested assumption ("CI can fetch from crates.io")
that Cachix had been hiding.
Cachix therefore stays as a READ-ONLY substituter until Attic has the paths. It
is credential-free (the cache is public) and nothing publishes to it any more:
pushes go to Attic, public on main and ci elsewhere. Drop these two lines once
Attic is seeded -- and expect that first uncached build to exercise the fetch
path for real.
The Attic side is confirmed working in the failing runs themselves: they
substituted python3-env and doctest from cache.nix.logos.co/public, and the push
step correctly skipped, since these repos have no public-cache environment yet.

logos-evm-wallet-ui
A Metamask-like QML UI (ui_qml) for the Logos multi-chain EVM wallet, over
wallet_backend_module.
It is QML-only — no C++/QtRO backend. The view drives the wallet backend
entirely through the injected logos bridge
(logos.callModule/callModuleAsync/onModuleEvent) against the backend's
JSON-string API, which keeps the UI simple and language-agnostic.
Tabs: Balances (per-chain + tokens, refresh), Send (native + ERC20 with
fee preview), Tokens (per-chain lists + add custom token), History (local
wallet-originated txs), Settings (proxy URL + fail-closed toggle). Live
updates come from the backend's balances_updated / tx_status_changed /
proxy_error events.
Build
nix build .#install # -> result/plugins/wallet_ui/ (QML + manifest)
The plugin declares wallet_backend_module as a dependency; a host
(logos-standalone-app / logos-basecamp) loads the UI plugin and auto-loads the
backend (and its dependency modules) alongside it.
