[Task] Prepare the TrustDB China profile GA release and claims review

[ryan-wong-coder]

Background

The release must package the validated profile and communicate its advantages without overstating external certifications or evidence status.

Scope

In scope:

• Freeze supported suites, providers, transports, BCOS versions, platforms, migration boundaries, limitations, and security advisories.
• Publish release artifacts, SBOM/provenance, checksums, test evidence, deployment docs, compatibility matrix, and upgrade/rollback guidance.
• Review README, website, SDK docs, examples, and sales claims for technical accuracy and approved wording.

Out of scope:

• Advertising formal MLPS, commercial cryptography assessment, product certification, legal timestamp, or judicial recognition before the scoped result exists.

Proof, storage, and compatibility impact

• Phase: Assessment
• Workstream: Compliance
• Risk: High
• Changes must preserve TrustDB evidence semantics, durable publication boundaries, bounded large-data behavior, and explicit trust roots.

Acceptance criteria

• All P0 GA gates are complete and the supported matrix is internally consistent.
• Install, deploy, offline verify, backup, restore, and rollback procedures pass from released artifacts.
• Claims state concrete product strengths and exact formal-status boundaries.

Validation plan

• Release candidate rehearsal, clean-room deployment, and signed checklist.
• Security/compliance/legal claims review.

Dependencies

• [Task] Run external pre-assessments and close high-risk findings #485
