fix(sbom): handle SPDX expression licenses in extract_licenses

[mesutoezdil]

CycloneDX allows licenses in 2 forms:

{"license": {"id": "MIT"}}; handled correctly

{"expression": "MIT OR Apache-2.0"}; silently dropped

extract_licenses only checked for the license key, so any component
using the expression form got an empty license field in the CSV output.

Add a check for expression before falling back to the license block.

PR Review Status

Validation: This is a small, concentrated SBOM tooling bug fix. The PR addresses a documented CycloneDX license form (expression) that the existing CSV export dropped, touches one deploy script, and no duplicate issue or PR was found for the same fix.
Head SHA: e18f4270b57875c60e817219db31c120e0c95bef

Review findings:

• No blocking findings remain.
• Non-blocking test note: there is no direct regression coverage for deploy/sbom/sbom_to_csv.py; a focused test for both {"expression": "MIT OR Apache-2.0"} and {"license": {"id": "MIT"}} would reduce reintroduction risk.

Docs: Fern docs update is not needed because this only changes generated SBOM CSV extraction behavior and does not alter a documented user-facing workflow, CLI contract, provider flow, policy syntax, or published API.

E2E: No test:e2e, test:e2e-gpu, or test:e2e-kubernetes label is needed for this SBOM CSV utility change.

Next state: gator:watch-pipeline

Maintainer Approval Needed

Gator validation and PR monitoring are complete.

Validation: This is a small, concentrated SBOM CSV extraction fix for CycloneDX SPDX expression licenses in deploy/sbom/sbom_to_csv.py.
Review: No blocking findings remain. I noted only non-blocking regression-test coverage risk for extract_licenses.
Docs: Fern docs update is not needed because this changes generated SBOM CSV extraction behavior only and does not alter a documented user-facing workflow, CLI contract, provider flow, policy syntax, or published API.
Checks: Required gates are green for head e18f4270b57875c60e817219db31c120e0c95bef: OpenShell / Branch Checks, OpenShell / Helm Lint, OpenShell / E2E, and OpenShell / GPU E2E.
E2E: No test:e2e, test:e2e-gpu, or test:e2e-kubernetes label was needed; the required E2E gate statuses passed as not applied.

Human maintainer approval or merge decision is now required.

Question: do we know how the CSV licenses column is consumed downstream? Preserving licenses[].expression verbatim seems right for review output, but an SPDX expression like MIT OR Apache-2.0 can represent multiple license choices. If any consumer splits this field expecting only individual SPDX IDs joined by |, we may need to document that the column can contain SPDX expressions or normalize it differently.

i v checked the repo, and no downstream consumer of the csv was found. resolve_licenses.py only processes json files and never touches the csvoutput. csv appears to be generated for manual review only.
if there is a known pipeline consumer expecting pipe-separated spdxids, i can normalize expression values before writing to the column. or verbatim seems fine as-is.. any case, happy to add a column comment/header note either way.

Re-check After Author Update

I re-evaluated latest head e18f4270b57875c60e817219db31c120e0c95bef after mesutoezdil's 2026-06-15 12:37 UTC response to the maintainer question about downstream consumers of the CSV licenses column.

Disposition: resolved for gator gating. I checked the repository references and found deploy/sbom/sbom_to_csv.py is the only in-repo CSV writer/reader for this SBOM CSV path, while deploy/sbom/resolve_licenses.py operates on CycloneDX JSON and does not consume the CSV output. Preserving the CycloneDX SPDX expression verbatim is still the least surprising representation for manual review output unless a maintainer knows of an external consumer that requires normalization.

Remaining items:

• No blocking gator items remain.
• A human maintainer still needs to make the approval or merge decision.

Next state: gator:approval-needed
