A pipeline with seams

[kasenur]

The word "plugin" usually means one of two things. Either a plugin is a
whole subsystem with its own configuration language (Nx executors), or
it is a callback bolted to one event the tool happened to expose. vx
uses the word the way Vite does: the core is a pipeline, every stage
has a named hook, and a plugin is an object that implements the hooks
it needs.

config → discover → project → graph → key → fingerprint → schedule

→ admit → executor / cache → telemetry
setup and teardown wrap the run; commands adds a verb

Stage
What a plugin can do there

config
See and adjust the workspace config before anything uses it.

discover
Name directories to make projects beyond the package manager's members.

project
Add, remove or edit one loaded project's tasks.

graph
Add or drop edges, mark tasks requested.

key
Contribute extra cache-key material per task.

fingerprint
Claim a lockfile out of the workspace fingerprint and key it per project.

schedule
Return a priority per ready task.

admit
Vet each local dispatch against what is running right now; false holds the task.
