…ANGED=N N is the number of changed tests to select, previously hardcoded at 50. Moved tests are now selected after added and modified ones, and the selection is logged at startup.
Keep the old name as an alias: it is what the eng-dev-ecosystem CI job dispatches.

local-select runs the same selection of changed tests locally against the testserver. TestInprocessMode is skipped under test selection: it asserts that two specific selftests ran, which does not hold when the selection excludes them.
A skip per test dir buried the run in ~1100 SKIP lines and hid the selection summary. local-select now runs plain `go test -v`, which shows the summary and the tests that ran.
A regenerated golden usually comes from a change elsewhere and lands on hundreds of dirs at once, which fills the quota and crowds out the tests the branch actually edits. Order is now added, changed fixture, changed output, moved.

Same rule the harness uses to split inputs from outputs, so a nested fixture such as subdir/outer.py is no longer mistaken for generated output.
Replace the four parallel maps with one map of a documented changedDir struct, pull the invariant-config and generated-file rules into named helpers, and rank by sorting once instead of concatenating four slices.
Scores instead of ranks, and the selection is now a real package rather
than test-only code, with a command to inspect what a change selects:
go run ./acceptance/internal/selection/cmd
go run ./acceptance/internal/selection/cmd acceptance/bundle/invariant/configs/job.yml.tmpl
A path given without a status prefix now takes the status git reports for it: added when git does not track it, modified otherwise. Each selected test is printed with the score it was picked by.
A dir that changed in several ways now outranks one that changed in a single way: new dir 5, changed fixtures 5, changed goldens 1, move 1. New and moved stay exclusive, and a move does not also count the renames of the files it brings along.

Localknob — every acceptance test runs locally now, so the variable only selects the tests a branch touches.
