Commit: feat: external-signer public uploads + single-chunk prepare/finalize across 15 SDKs (#90)

Source artifacts inspected

• antd-mcp/src/antd_mcp/server.py at a3cf4e4 — new tool functions prepare_upload_public, prepare_chunk_upload, finalize_chunk_upload; updated prepare_upload signature and finalize_upload docstring
• antd-mcp/README.md — tool count 14 → 18, updated tool table
• antd-js/src/models.ts — FinalizeUploadResult gains dataMap: string and dataMapAddress: string; new PrepareChunkResult interface
• antd-py/src/antd/models.py — FinalizeUploadResult gains data_map and data_map_address; new PrepareChunkResult dataclass
• antd/openapi.yaml — unchanged

Developer-facing change

antd-mcp gains four new external-signer tools: prepare_upload now accepts an optional visibility parameter, prepare_upload_public is a convenience wrapper for public uploads, and prepare_chunk_upload / finalize_chunk_upload handle single raw chunks without a daemon wallet. FinalizeUploadResult in JS and TS bindings gains dataMap and dataMapAddress fields.

Files changed in this PR

• docs/mcp/mcp-server-reference.md — external-signer tools section updated
• docs/sdk/reference/language-bindings/javascript.md — FinalizeUploadResult type mapping updated
• docs/sdk/reference/language-bindings/typescript.md — FinalizeUploadResult type mapping updated

Why prose changed

mcp-server-reference.md: The external-signer tools section previously documented 4 tools (prepare_upload, prepare_data_upload, finalize_upload, finalize_merkle_upload). The upstream commit adds prepare_upload_public, prepare_chunk_upload, and finalize_chunk_upload, and updates prepare_upload's signature to accept an optional visibility parameter. finalize_upload and finalize_merkle_upload now return data_map and data_map_address fields. Tracked by antd-mcp/src/antd_mcp/server.py at a3cf4e4.

javascript.md / typescript.md: The inline FinalizeUploadResult type literal was missing the new dataMap and dataMapAddress fields added in antd-js/src/models.ts at a3cf4e4.

Verification run

• Scanner re-run on prose branch: status: ok, 0 drifted records for the 3 prose pages
• New tool signatures confirmed against server.py at a3cf4e4
• FinalizeUploadResult fields confirmed against antd-js/src/models.ts at a3cf4e4
• No SKILL.md body changes; linked-release rule not triggered
• Sweep envelope: no change to scripts/, .github/, repo-registry.yml, component-registry.yml

Deferred ambiguous records

None.

Uncertainties

The use-external-signers-for-upload-payments.md how-to guide already documents the single-chunk prepare/finalize REST flow (/v1/chunks/prepare, /v1/chunks/finalize) and the visibility:"public" parameter. Confirming those pages needed no prose update — their content was already accurate before this commit (the REST endpoints pre-existed; this commit adds SDK client wrappers only).
