@@ -263,6 +263,7 @@ Each agent type needs:
 - **CI must build `agent-os-sidecar` before TypeScript integration tests.** `packages/core` and registry integration suites talk to the native sidecar binary; if the workflow only runs `pnpm test`, it is not exercising the same path developers use locally.
 - **CI should run both `cargo test --workspace --no-fail-fast` and the ignored sidecar integration suite.** The four slow sidecar isolation tests are intentionally marked `#[ignore]` for local ergonomics, so the workflow needs a dedicated `cargo test -p agent-os-sidecar -- --ignored --test-threads=1` step to keep them covered.
 - **Cache the expensive layers explicitly.** Reuse pnpm store, workspace `node_modules`, and Rust `target/`/cargo caches in CI; otherwise this repo's mixed Rust/TS pipeline gets too slow to iterate on.
+- **Cross-crate Rust test helpers must use repo-relative paths, never machine-local absolute paths.** `#[path = "..."]` includes under `crates/*` are compiled on CI runners with different checkout roots, so absolute developer paths like `/home/nathan/...` will break `cargo test --workspace`.
 - **Local CI reproduction:** `git lfs pull && cargo test --workspace --no-fail-fast && cargo test -p agent-os-sidecar -- --ignored --test-threads=1 && cargo build -p agent-os-sidecar && AGENTOS_E2E_NETWORK=1 pnpm test`
 - **Framework**: vitest
 - `packages/core/tests/` is grouped by domain under `unit/`, `filesystem/`, `process/`, `session/`, `agents/{pi,claude,opencode,codex}/`, `wasm/`, `network/`, `sidecar/`, and `cron/`. When moving or adding tests, rebase relative `../src` and `helpers/` imports plus any `moduleAccessCwd` or repo-root paths to match the subdirectory depth.
