Adds an AETHER-specific verification profile and thin caller for the MelodicBloom control plane. This slice is intentionally expected to expose the missing package-lock.json as a blocking reproducibility failure. It separately declares WebGL runtime, context recovery, shader fallback, keyboard drawer, focus return, reduced motion, canvas fallback, renderer cleanup, and manual evidence omissions. No source, shader, token, dependency, deployment, or secret changes. Do not merge until the central control-plane PR is reviewed and the lockfile/test evidence gaps are resolved.

Verified canary result

The caller is now pinned to corrected control-plane SHA 597d76aa36c833f8374b1756e4db46244e012323.

The new run proves the shared workflow sequencing defect is resolved:

• checkout: passed
• Node setup: passed
• verification profile presence: passed
• profile/repository identity validation: passed
• frozen dependency contract: failed

The failure is now correctly attributable to AETHER: package-lock.json is absent. Lint, typecheck, build, specialized WebGL/accessibility checks, artifact hashing, and success receipt were skipped and are not represented as passed.

Smallest safe next change

Create a lockfile-only follow-up from this branch using a clean dependency resolution, then verify npm ci, npm run typecheck, npm run lint, and npm run build before expanding behavioral QA. Keep this PR draft until that reproducibility gate is satisfied.

Superseded by PR #7 as the canonical reproducibility/evidence layer and by issue #9 for runtime WebGL browser evidence. PR #3 already carries the verified lockfile/lint repair on the runnable-gallery branch. Keeping this thin caller open would preserve a second verification path with stale assumptions, so it should close without merge.

Marked superseded by PR #10, which consolidates the reproducibility repair and evidence chain. This PR remains closed for historical comparison.
