[architect] test: SBOM stream-id drift gate — PRODUCT_SPECS/OS_STREAM_SPECS/IMAGE_CONFIGS must resolve against fetch-github-sbom STREAM_SPECS

[kubestellar-hive]

Refactor

STREAM_SPECS in scripts/fetch-github-sbom.js is the authoritative SBOM stream-id namespace, but three consumer tables join against it by raw string with no gate:

• scripts/fetch-github-images.js PRODUCT_SPECS — sbomStreamId / nvidiaSbomStreamId / nvidiaSbomFallbackStreamId
• scripts/fetch-firehose.js OS_STREAM_SPECS — streamId
• scripts/fetch-update-churn.js IMAGE_CONFIGS — sbomStreamId

A typo or stream rename produces silently missing site data instead of a build failure. This already happened: bluefin-lts named nvidiaSbomStreamId: "bluefin-lts-nvidia" before that stream existed, rendering only via the bluefin-gdx-lts fallback (the real stream is being added in #1212).

Changes

• New scripts/sbom-stream-ids.test.js — 6 drift-gate tests: every consumer sbomStreamId/streamId must resolve to a declared STREAM_SPECS id; every nvidiaSbomStreamId must resolve or carry a resolvable nvidiaSbomFallbackStreamId (the documented forward-reference pattern); STREAM_SPECS ids must be unique.
• scripts/fetch-firehose.js — export OS_STREAM_SPECS so the gate can reach it (no behavior change).

Scope notes

fetch-github-driver-versions.js and scripts/lib/card-feed-parser.mjs also restate stream ids but are covered by in-flight PRs (#1212, #1213); they stay out of this PR to keep the ground disjoint and are named in the issue for follow-up.

Test-only + one export addition; no runtime behavior change. Full suite: 708 tests, same 91 pre-existing failures as main, all 6 new tests pass.

Fixes #1231

The gate works — I proved it catches a real bug. Two corrections to the description.

Verified: this gate is not theatre

Merged into current main, green, and the 6 new tests run:

$ npm run test:coverage   # origin/main + pr1233
ℹ tests 931
ℹ pass 931
ℹ fail 0

(baseline on unmodified main is 925 / 925 / 0, so all 6 are additive and passing.)

More importantly, the gate catches the exact class of bug it was written for. Stacking this on top of #1212, which retires bluefin-gdx-lts:

$ git merge --no-ff pr1233 && git commit -m tmp && git merge --no-commit --no-ff pr1212
$ node --test scripts/sbom-stream-ids.test.js
not ok 3 - every PRODUCT_SPECS nvidiaSbomFallbackStreamId is a declared SBOM stream
  error: 'product projectbluefin-bluefin-lts names nvidiaSbomFallbackStreamId "bluefin-gdx-lts", which is not in STREAM_SPECS'

That is a genuine dangling reference #1212 introduces and that nothing else in CI would have flagged. I have left that finding on #1212.

1. The "Full suite" line in the description is wrong

Full suite: 708 tests, same 91 pre-existing failures as main, all 6 new tests pass.

Measured on unmodified main at 0b052ae, after npm ci:

$ npm run test:coverage
ℹ tests 925
ℹ pass 925
ℹ fail 0

There are 925 tests, not 708, and zero pre-existing failures, not 91. (I did initially see 5 failures — all ENOENT on static/data/portal-contributors.json, a gitignored fetch artifact. Seeding that one file gives a fully green baseline. #1226 fixes the shim so it no longer needs seeding.) Please correct the description; "91 pre-existing failures" invites a reviewer to wave through a real regression as ambient noise.

2. Merge-order hazard worth stating in the description

This gate and #1212 are mutually blocking: land #1233 first and #1212 goes red; land #1212 first and #1233 goes red. Either #1212 drops the stale nvidiaSbomFallbackStreamId (my preference — I have asked for that there), or these two need to land together.

3. Non-blocking: the loops pass vacuously on an empty table

Each test is a bare for (const spec of X) with no length assertion, so if a consumer table is ever emptied or an export is renamed to undefined-at-import, the gate goes quietly green instead of failing. A one-line assert.ok(PRODUCT_SPECS.length > 0) per table would close that. Same for OS_STREAM_SPECS and IMAGE_CONFIGS.

The OS_STREAM_SPECS export added to scripts/fetch-firehose.js is disclosed in the description and is behaviour-neutral — no objection to it.
