…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.
An added config adds a variant of every invariant dir, so it now scores 10 where changing an existing config scores 5. The companion setup scripts of a config only change how an existing variant runs, so they stay at 5.
Three fixes, all in the selection package: - Two changed invariant configs produced two INPUT_CONFIG filters for the same dir. The harness requires every filter to match, so every variant skipped and those dirs ran nothing while still filling the quota. Such a dir now runs all of its variants. This one predates the branch. - A dir that was both new and moved scored 6; new and moved are meant to be exclusive, and it now scores as new. - The command resolved a bare path with a path-scoped git diff, which cannot pair a rename and reports the destination as added, so a moved test ranked as new. It now reads one whole diff, which also drops two git processes per argument, and rejects a non-positive limit instead of panicking on a negative slice bound.
…test Two changed invariant configs produced two INPUT_CONFIG filters for the same dir, and the harness required every filter to match, so every variant skipped and those dirs ran nothing. The environment has one value per key, so filters sharing a key now mean any of them: two changed configs run the variants of both. This also makes ENVFILTER=INPUT_CONFIG=a,INPUT_CONFIG=b run both variants rather than none, and lets checkEnvFilters reuse one matcher. acceptance/selftest/selection prints what the selection command reports for a changed test, a new test, a regenerated golden, a moved test, a touched invariant config, and a new config alongside two touched ones.
A dir restricted to some of its variants printed them merged into one line, which read like a syntax of its own. Each variant is now its own line, named bundle/invariant/no_drift/INPUT_CONFIG=job.yml.tmpl.
Adding one invariant config marked the whole dir as new, so the variants of the configs that were merely changed scored as new too. A variant is now the unit of selection: it carries its own score, and only the new config's variant counts as new. The command prints each selected test as a name go test accepts, expanded from the variant matrix in the test's materialized config, so a line can be run as printed. It is built by the harness like the CLI is, because tests run with a sandboxed HOME that has no module cache.
The test built a tree of its own because a committed directory holding a file named "script" would be picked up as a test case. Pointing -root at the real tree instead drops that setup, exercises the real variant matrices, and prints names that name existing tests. The golden now moves when an invariant test dir or its matrix changes.
