Reliable metadata handoff and runtime binding #316

🤖 Generated by the Agentic Engineer

Audience and problem

Product publishers need reliable declaration and report workflows. Consumers and operators need public metadata and readiness observations to agree with the declared interfaces.

Intended outcome

Resolve the independently reproducible defects found in this round's consumer, publisher and runtime audits. Each delivered child has a failing regression, a focused repair, current-head review and a merged delivery PR. Preserve independent product hosting and existing adoption gates.

Acceptance criteria

• Deliver at least ten distinct child issues through merged PRs.
• Exercise the affected user paths and retain valid-input controls.
• Keep documentation aligned with the resulting behavior.

Part of #283.
