Same layering rule as the previous commit, one construct over. The remediation text explained how nix wires the var and pointed at `nix/assets.nix` -- a path that does not exist either, so it carried both defects this branch is about. What a developer hitting this panic needs is the layout to point at, which is a fact about this crate.

//! Resolve the on-disk path to hyperhive's static assets (branding +
|
|
//! claude prompts). Single source of truth for both the host daemon
|
|
//! (`hive-c0re`) and the in-container harness binaries so they agree
|
|
//! on the lookup contract.
|
|
//!
|
|
//! At runtime, the path is read from `$HIVE_ASSETS_DIR`. Setting it is
|
|
//! the deployment's job; this crate's contract is only that it names a
|
|
//! directory laid out like the packaged assets.
|
|
//! For `cargo run` outside nix, set it yourself:
|
|
//!
|
|
//! ```sh
|
|
//! HIVE_ASSETS_DIR=$(pwd)/dev-assets cargo run ...
|
|
//! ```
|
|
//!
|
|
//! where `dev-assets/` mirrors the nix output's `branding/` + `prompts/`
|
|
//! layout.
|
|
//!
|
|
//! Each crate that wants a specific asset goes through one of the
|
|
//! typed helpers (currently just `prompt_template()` — the branding
|
|
//! SVG used to live here too; the per-agent icon now 404s server-side
|
|
//! when unconfigured and falls back to a frontend-bundled default
|
|
//! client-side instead of a server-resolved runtime path, see
|
|
//! `hive-agent::web_ui::screen::serve_icon`) so the lookup contract is
|
|
//! centralised. Missing files panic at first call with a clear "set
|
|
//! `HIVE_ASSETS_DIR` + put the file at …" message.
