 Recent cross-shell regressions for `openspec` commands revealed that our existing unit/integration tests do not exercise the packaged CLI or shell-specific behavior. The prior attempt at Vitest spawn tests stalled because it coupled e2e coverage with `pnpm pack` installs, which fail in network-restricted environments. With those findings incorporated, we now need an approved plan to realign the work.
 
 ## What Changes
-- Adopt a phased strategy that first stabilizes direct spawn testing of the built CLI (`node dist/cli/index.js`) using lightweight fixtures and shared helpers.
-- Expand coverage to cross-shell/OS matrices once the spawn harness is stable, ensuring both the direct `node dist/cli/index.js` invocation and the bin shim are exercised with non-TTY defaults and captured diagnostics.
+- Adopt a phased strategy that first stabilizes direct spawn testing of the built CLI (`node dist/cli/index.js`) using lightweight fixtures and a shared `runCLI` helper.
+- Expand coverage once the spawn harness is stable, keeping the initial matrix focused on bash jobs for Linux/macOS and `pwsh` on Windows while exercising both the direct `node dist/cli/index.js` invocation and the bin shim with non-TTY defaults and captured diagnostics.
 - Treat packaging/install validation as an optional CI safeguard: when a runner has registry access, run a simple pnpm-based pack→install→smoke-test flow; otherwise document it as out of scope while closing remaining hardening items.
+- Close out the remaining cross-shell hardening items: ensure `.gitattributes` covers packaged assets, enforce executable bits for CLI shims during CI, and finish the pending SIGINT handling improvements.
 
 ## Impact
-- Tests: add `test/cli-e2e` spawn suite, helpers, and fixture usage updates; adjust `vitest.setup.ts` as needed.
-- Tooling: update GitHub Actions workflows to add shell/OS matrices and (optionally) a packaging install check where network is available.
-- Docs: keep `CROSS-SHELL-PLAN.md` aligned with the phased rollout and record any limitations called out during execution.
+- Tests: add `test/cli-e2e` spawn suite, create the shared `runCLI` helper, and adjust `vitest.setup.ts` as needed.
+- Tooling: update GitHub Actions workflows with the lightweight matrix above and (optionally) a packaging install check where network is available.
+- Docs: note phase progress and any limitations inline in this proposal (or the relevant spec) so future phases have clear context.
+
+### Phase 1 Status
+- Shared `test/helpers/run-cli.ts` guarantees the CLI bundle exists before spawning and enforces non-TTY defaults for every invocation.
+- New `test/cli-e2e/basic.test.ts` covers `--help`, `--version`, a successful `validate --all --json`, and an unknown-item error path against the `tmp-init` fixture copy.
+- Legacy top-level `validate` exec tests now rely on `runCLI`, avoiding manual `execSync` usage while keeping their fixture authoring intact.
+- CI matrix groundwork is in place (bash on Linux/macOS, pwsh on Windows) so the spawn suite runs the same way the helper does across supported shells.

 ## 1. Phase 1 – Stabilize Local Spawn Coverage
-- [ ] 1.1 Update `vitest.setup.ts` and helpers so the CLI build runs once and `runCLI` executes `node dist/cli.js` with non-TTY defaults.
-- [ ] 1.2 Reuse the minimal fixture set (`tmp-init` or copy) to seed initial spawn tests for help/version, a happy-path `validate`, and a representative error flow.
-- [ ] 1.3 Document the Phase 1 coverage details in `CROSS-SHELL-PLAN.md`, noting any outstanding gaps.
+- [x] 1.1 Add `test/helpers/run-cli.ts` that ensures the build runs once and executes `node dist/cli/index.js` with non-TTY defaults; update `vitest.setup.ts` to reuse the shared build step.
+- [x] 1.2 Seed `test/cli-e2e` using the minimal fixture set (`tmp-init` or copy) to cover help/version, a happy-path `validate`, and a representative error flow via the new helper.
+- [x] 1.3 Migrate the highest-value existing CLI exec tests (e.g., validate) onto `runCLI` and summarize Phase 1 coverage in this proposal for the next phase.
 
 ## 2. Phase 2 – Expand Cross-Shell Validation
-- [ ] 2.1 Exercise both entry points (`node dist/cli.js`, `bin/openspec.js`) in the spawn suite and add diagnostics for shell/OS context.
-- [ ] 2.2 Extend GitHub Actions to run the spawn suite across a matrix of shells (bash, zsh, fish, pwsh, cmd) on macOS, Linux, and Windows runners.
+- [ ] 2.1 Exercise both entry points (`node dist/cli/index.js`, `bin/openspec.js`) in the spawn suite and add diagnostics for shell/OS context.
+- [x] 2.2 Extend GitHub Actions to run the spawn suite on bash jobs for Linux/macOS and a `pwsh` job on Windows; capture shell/OS diagnostics and note follow-ups for additional shells.
 
 ## 3. Phase 3 – Package Validation (Optional)
 - [ ] 3.1 Add a simple CI job on runners with registry access that runs `pnpm pack`, installs the tarball into a temp workspace (e.g., `pnpm add --no-save`), and executes `pnpm exec openspec --version`.
-- [ ] 3.2 If network-restricted environments can’t exercise installs, document the limitation in `CROSS-SHELL-PLAN.md` and skip the job there.
-- [ ] 3.3 Close out remaining hardening items from the original cross-shell plan (e.g., `.gitattributes`, chmod enforcement, SIGINT follow-ups) and update the plan accordingly.
+- [ ] 3.2 If network-restricted environments can’t exercise installs, skip the job and note the limitation in this proposal’s rollout log.
+- [ ] 3.3 Close out the enumerated hardening items: extend `.gitattributes` to cover packaged assets, enforce executable bits for CLI shims during CI, and finish the outstanding SIGINT handling work; update this proposal once they land.
