- plugins: vet, short tests and the additive-export check of the user
(GOWORK=off, against 930b158 and v0.1.9), OAuth server (d31f8e7) and blog
(ffa2c8f) plugins, the blog plugin's MCP tests by name
- consumers: the three applications build and pass at their pins, the demo
also with the MCP tag; the pin check accepts a plugin submodule ahead of
its pin only by test-only commits
- docker: the cabana, user plugin, OAuth server and demo Postgres suites by
name
- docs: decision note and STACK rows, docs checks, no consuming application
named in sources, docs or the phase's tests
- self-test proves additive_check on a planted repository
