`web/package-lock.json` was updated by the design-system refactor
(merged via #17007 + follow-ups: spinner / select / badges / buttons)
without bumping `nix/web.nix::npmDeps.hash`, breaking nix builds on
every PR + main since 2026-04-28T18:46.
Hash sourced from the actual `Check flake` failure output:
specified: sha256-AahWmJ9gDQ9pMPa1FYwUjYdO2mOi6JM9Mst27E0vp68=
got: sha256-+B2+Fe4djPzHHcUXRx+m0cuyaopAhW0PcHsMgYfV5VE=
Standalone single-file fix so it can land fast and clear nix on
every other open PR.
* fix(nix): use --rebuild in fix-lockfiles to bypass cached FOD store paths
fix-lockfiles checked npm lockfile hashes by running
`nix build .#<attr>.npmDeps`, but fetchNpmDeps is a fixed-output
derivation — if the old store path exists locally, Nix returns it from
cache without re-fetching. This caused the script to report "ok" even
when hashes were stale, while CI (with no cache) failed with a hash
mismatch.
Adding --rebuild forces Nix to re-derive and verify the output hash
against the declared one, catching staleness regardless of local cache
state. Also updates the tui and web npm deps hashes that were stale.
* fix(nix): regenerate ui-tui lockfile to add missing @emnapi entries
npm ci was failing because @emnapi/core and @emnapi/runtime were
missing from ui-tui/package-lock.json despite being required as peer
deps by @napi-rs/wasm-runtime (via @rolldown/binding-wasm32-wasi).
Running npm install --package-lock-only adds the missing entries.
The npmDepsHash reverts to its previous value since fetchNpmDeps was
already fetching these packages as transitive dependencies.
The web dashboard (Vite/React frontend) is now built as a separate Nix
derivation and baked into the Hermes package. The build output is
installed to a standard location and exposed via the `HERMES_WEB_DIST`
environment variable, allowing the dashboard command to use pre-built
assets when available (e.g., in packaged releases) instead of rebuilding
on every invocation.
