[JimCollinson]

Upstream

• ant-sdk: 7a113b390522d76d28b8f3e5b4078f9c9418d46f → 7853b76d99ef9e308140b763f23d043559b204c4

Source artifacts inspected

• antd/src/rest/upload.rs — removal of 501 guard for visibility:"public" on /v1/data/prepare
• antd/src/types.rs — updated PrepareDataUploadRequest doc comment
• antd/openapi.yaml — unchanged between SHAs (spec is stale relative to code; noted in Uncertainties)
• antd-rust/src/client.rs — updated doc comment for prepare_data_upload
• antd-php/src/AntdClient.php — tx_hashes cast to object for correct JSON serialization
• antd-go/README.md, antd-js/README.md, antd-py/README.md — added External Signer section
• antd-cpp/include/antd/async_client.hpp, antd-java/…AsyncAntdClient.java — new wallet and external-signer methods on async clients

Developer-facing change

The most significant runtime change is that visibility:"public" is now accepted on POST /v1/data/prepare (previously returned 501). That is a prose change handled in the companion PR claude/prose-2026-05-28-data-prepare-public. All other changes in this range — PHP tx_hashes serialization fix, new C++/Java async client methods, documentation of Go/JS/Python external-signer helpers in their READMEs — have no impact on the content of the metadata-only pages stamped here.

Files changed in this PR

• 46 docs verification blocks (source_commit + verified_date for ant-sdk only)
• skills/start/version.json — verified_commits.ant-sdk refreshed
• skills/start/SKILL.md — frontmatter verified_commits.ant-sdk and verified_date refreshed
• planning/sweeps/2026-05-28.md — new sweep summary

Verification run

• Re-ran python3 scripts/sweep_poll.py on this branch: status: "ok", 2 records still drifted (the two prose-PR pages, as expected).
• No markdown linter configured; skipped.
• No link checker configured; skipped.
• Confirmed no prose text outside <!-- verification: --> blocks was modified (only source_commit:, verified_date:, and verified_commits map values changed).
• Confirmed skills/start/SKILL.md body is byte-identical to base — no linked release triggered.
• Confirmed prose PR pages (docs/sdk/reference/rest-api.md, docs/sdk/how-to-guides/use-external-signers-for-upload-payments.md) are not touched by this PR.

Uncertainties

The antd/openapi.yaml at head_sha still documents visibility:"public" on /v1/data/prepare as returning 501 — the spec lags the implementation. The prose PR corrects the rendered docs based on the actual code behavior. A reviewer may wish to open a separate issue to track the stale OpenAPI spec upstream.
