Development record

The launch chapter says the light tier fails a file present in the tree but excluded from the payload (.abcd/development/brief/04-surfaces/04-launch.md:438), and it counts the convention register, the command, agent, skill and hook paths a plugin is expected to carry, in the declared surface (lines 423-424). conventionEntries lists only what the payload tree already holds (internal/core/launch/installsurface.go:349), so a page reached by convention but outside the includes yields no entry and no finding. Only a path declared explicitly, by a plugin.json key or a hook command, gives the missing-path finding (internal/core/launch/smoke.go:123-127, internal/core/launch/smoke_test.go:47,53).
