Platform-ecosystem prior-art survey

Overview

A team designing a plugin system reinvents every hard decision Shopify, VS Code, Slack, WordPress and Chrome each took years to settle. The evidence for those decisions is public, documented, and almost never gathered. This skill gathers it: a searched, recorded corpus, then one deep read per admitted mechanism, then a decision index built by cutting ACROSS that corpus — one row per decision the downstream document must make, each carrying the records it rests on.

You are one child of a survey, running ONE assignment: either the wave-0 vocabulary map, or one search angle. You never run the whole survey and never read another angle's output.
