Summary

• Add eight developer documentation pages for the @voidly/session 1.4.3 public source: quickstart, concepts, callable API examples, subpaths, complete export index, errors, and FAQ.
• Link the pages from the root README and llms.txt and include docs in Context7, preserving the existing hosted MCP discovery, license, trademarks, and proof boundaries.
• Make the current payment rule clear across the README, SDK guide/example, and new docs: a human owner reviews and signs each current Voidpay payment in the browser. The published EIP-3009, EIP-1193, and customer-hosted SDK APIs remain documented as source capabilities, not unattended agent payment authority.

Validation

• Built against public main 50a5ee9a57ea0fbeba38155ee1e2e223e9289535. Forward and reverse git apply --check --whitespace=error passed on the exact base.
• All eight docs pages, Markdown fences, JSON blocks, relative links, root hosted MCP/license/trademark sections, and Context7/llms.txt indexing were checked.
• Add the offline docs drift checker and PR workflow in a second commit. The checker compares the documented exports, examples, outcome tags, and links with checked-out public source; its CI result is the gate for this PR.
• No package build/test/install, live provider call, payment, or checkout was run locally for this docs change.

The docs and examples do not establish provider readiness, customer demand, or an autonomous payment path. The first-party settlement receipt remains mechanism evidence.
