nix-export-interop

Independent **package-manager** harness in `zed-pkg-test` for `zed-pkg`.

**Readiness:** `ready`  
**Primary dependency strategy:** `matrix`  
**Scheduled cadence:** `17 5 * * *` UTC  
**Live infrastructure:** Nix

## Upstream repositories

- `zed-pkg/zed-cli`

• zed-pkg/zed-interfaces

  Acceptance objectives

  1. Verify deterministic Zed-to-Nix export, immutable hashes, and repeatable offline builds across the supported happy-path states and canonical fixtures.

2. Verify deterministic Zed-to-Nix export, immutable hashes, and repeatable offline builds under retries, interruption, concurrency, offline operation, or partial failure.

3. Verify deterministic Zed-to-Nix export, immutable hashes, and repeatable offline builds preserves authorization, idempotency, integrity, observability, and actionable failure classification.

   Dependency paths

   This repository tests the upstream through independent installation paths:

   1. ./scripts/bootstrap-upstream.sh git-submodule
   2. ./scripts/bootstrap-upstream.sh zed
   3. ./scripts/bootstrap-upstream.sh native-package

   The publisher materializes a real Git submodule when authenticated access is available. Zed and native package coordinates are recorded in dependency-contract.yaml; missing unpublished packages are reported as blocked readiness rather than silently skipped.

   Check tiers

   python3 -m pip install -e '.[test]'
   pytest -q
   ./scripts/readiness.py --offline
   ./scripts/run-live.sh

   Pull requests validate the harness and deterministic contract fixtures. Secret-, service-, emulator-, desktop-, database-, provider-, chaos-, scale-, and soak-dependent checks run by schedule or manual dispatch.

   A live result must be classified as one of:

   • product regression — a behavioral invariant fails after dependencies are ready;
   • blocked dependency — an upstream, credential, package, emulator, provider sandbox, or deployment is unavailable;
   • harness regression — generated metadata, fixtures, workflow, or runner setup is invalid.
