C1: Source-of-truth adjudication — verified-facts record for opencode v2.0.23 #24

ParentPart of #23 (Spec: opencode-architect 1.0.0)## What to buildA verified-facts record that becomes the single authority for every opencode v2 API fact our guidance asserts. Pin anomalyco/opencode at tag v2.0.23 and record the commit hash and snapshot date. For each contradiction and each surface the suite teaches, adjudicate by the source-of-truth ladder: pinned source > official v2 docs > DeepWiki. Inputs include the live v1ΓåÆv2 migration guide, whose assertions are validated against source before our guidance may repeat them.Surfaces to settle, at minimum: the plugin-authoring package name and its subpath exports (Effect and Promise variants); plugin definition shape, lifecycle, and storage; the agent domain transform; permission semantics, action vocabulary, and the fate of external-directory permissions; config schema keys (registration array, permissions, agents, commands, MCP servers, skills) and each v1ΓåÆv2 mapping; tool registration, argument schema style, and result shape; discovery directories for extensions; install/distribution mechanics (npm vs local vs file-based registration, cache locations, loading order, precedence); the hook-family map from every v1 hook we teach to its v2 replacement; the TUI, RPC, and Effect surfaces we will recommend; and command/skill/agent frontmatter field changes.Each recorded fact cites its source and locator. Facts the source cannot settle are explicitly marked for empirical confirmation by the verification harness.## Acceptance criteria- [x] Record exists, pinned to v2.0.23 with commit hash and snapshot date- [x] Every contradiction surfaced in research has an explicit resolution or an explicit open flag- [x] Every v1 hook/config fact our current guidance asserts has a v2 replacement or removal recorded- [x] Facts needing empirical confirmation are listed as inputs for the verification harness ticket- [x] No unverified claim is stated as settled## Blocked by- None (can start immediately)
