M0 (the stream-json spike) was completed earlier but its code was left
uncommitted in a sibling worktree and never landed on any branch. This
commits it verbatim as the M1 baseline:
- NucleicCore: AgentEvent/JSONValue model, AgentBackend protocol,
ApprovalCoordinator, ProcessHost, Transcript writer/reader,
ClaudeStreamDecoder, in-process MCP approval server, ClaudeCodeBackend
- nucleic-spike CLI + fake-claude wire stub
- 41 hermetic tests (golden + contract + drift) and live captures under
fixtures/claude/2.1.167/
- PLAN.md / ADAPTERS.md updated with M0 findings; docs/M0_RESULTS.md
Built and tested with `swift build/test --build-system native` (iCloud
codesign workaround).
