feat(api): select qualified runtime/kernel pairs for system builds - #1579
Extend the existing system-template build endpoint with an optional immutable environment reference. Omitting it preserves the bundled-recipe behavior and the old request fingerprint.
Add GET /admin/api/v1/system-template-environments for the catalog's qualified runtime/kernel pairs. This is a qualification catalog, not a builder-readiness claim.
Carry explicit selection through the existing fail-closed environment wire arm, require the node gateway's acknowledgement, and make the selected kernel authoritative for scratch seed builds.
Include selection in idempotency fingerprints, and record accepted jobs before validating acknowledgement so ambiguous acceptance is not blindly retried.
Construct legacy and environment-selected wire requests directly, without mutation, and preserve the builder's acknowledgement in the returned response.
Add space-admin-cli template build seed --environment <reference>. Legacy requests omit the field entirely, so they still work with older APIs.
API
POST /admin/api/v1/system-templates/seed/buildsContent-Type: application/json
{
"environment": "sha256:6e97c03b2523af6cc7b8e67bcde3fd89cf756c1958b10c24472aeadd68a32e0a",
"publish_tags": []
}
This pair is Firecracker 1.17.0 / Linux 6.1.155 / x86_64. The request builds seed independently of any other template. Neither building nor selecting a pair changes cluster defaults or promotes latest.
Older API servers reject the new field through the existing deny_unknown_fields request contract. Older gateways/builders cannot silently interpret explicit selection as a legacy recipe build.
Validation
cargo fmt --all -- --check
Targeted controller wire-arm/grant unit test: passed.
System-build idempotency integration tests: 2 passed, with required Docker dependencies.
Admin CLI request tests: 3 passed.
Full ci/scripts/run-rust-checks.sh clippy feature matrix.
Real Linux/KVM KIND proof: the typed UI-to-builder scenario passed on an isolated test cluster, including guest commands, filesystem persistence, and suspend/restore. Runtime inspection read the running VM's executable, not just configured metadata: Firecracker v1.17.0. The guest reported 6.1.155+.
The final seed-only build job was 01a1adf2-e2e4-713e-9ab9-829e769498a1, producing seed@blake3:01f3095c15629ab617d44db0f2db94f58f79c98dc73593c1dc8782773e25b909. The build/boot/guest/lifecycle phase took 49.7 seconds on the warm bench. The scenario reported verdict: pass, no unexpected browser errors, and no cleanup failures. Task-owned sandboxes and unpromoted releases were cleaned up, without moving latest.
Review follow-up: the acknowledgement-retention regression failed with the old environment: None return value and passes after forwarding the response. Both legacy (None) and selected (Some) cases pass, along with the direct-construction wire-arm/grant test and the full clippy matrix.
Operational boundary
No production deployment, policy change, or promotion. The local KIND bench staged the 1.17 runtime and selected kernel and explicitly admitted the qualified pair. Production builders must likewise have the artifacts and policy admission before using this selection.
Severity and risk
Severity: operational feature, not an incident fix. Risk: explicit seed builds require matching qualified runtime/kernel artifacts and policy admission across the API, gateway, and builder. Deploy the backend before the companion UI; selection does not change cluster defaults or promote tags. Roll back the feature before accepting new explicit-pair requests.
AI assistance: Computer (GPT) updated this description during review follow-up; no API code was changed in that follow-up.
UI
The companion admin UI PR, #1580, adds a seed-only builder in System templates, independent seed promotion through the existing tag controls, and screenshot links outside the repository.
System-template build requests can include an optional qualified runtime/kernel environment. The admin API lists available pairs, forwards a selected pair to the builder, includes it in idempotency fingerprints, and checks the builder’s acknowledgement. The admin CLI accepts the optional selection. Requests that omit it retain the bundled-recipe path.

Explanation
Bug Fixes Name A Regression Test
The PR adds environment selection and preserves legacy build behavior. The reviewed diff does not show a fix for a defect in existing application behavior, so the check does not apply.
Weakened Safeguards Are Justified
The diff retains the existing test assertions or replaces them with equivalent checks. It does not remove or weaken a lint, CI check, or repository guard.
Add coverage for a successful acknowledgement mismatch.
The fixture only simulates a transport failure or echoes the requested environment. Add a toggle that returns environment: None or a different reference for an explicit selection.
Assert that the request is not accepted and that fixture.job_id is recorded. Replay with the same Idempotency-Key and body must return the unknown-outcome conflict with the known job ID and must not dispatch a second job.
Removing the comparison currently remains undetected. Inverting it is already detected by the explicit-selection test, which expects ACCEPTED for a matching acknowledgement.
