lint:test-mocks counts vi.mock/vi.doMock of src/config, src/nest/realtime and src/db per file under tests/, lint:test-new-service counts new XService(/new XRepository( there with every class whose constructor takes nothing allowed (derived from src/ and tests/helpers/), and lint:size holds files under tests/ to 2000 lines against their own baseline. Both counters share scripts/lib/count-ratchet.mjs, which gains a prepare hook for a check that reads the tree first. The three run as steps of the existing server lint job; the CLAUDE.md files and the module guide describe the test helpers they point to.
Both server ratchets only logged an entry the tree had moved past. A
file that shrank could grow back to its old size entry unseen, a
deleted file left its allowance to the next file at its path, and a
boundary violation that was fixed stayed allowed until someone ran
--update. The client ratchets now fail on such entries, so the server
ones do the same.
lint:size fails on an entry above its file's size or for a file that is
gone, and lint:boundaries on an entry that no longer occurs; both tell
to run --update, which still only lowers or drops. Both baselines match
the tree today.
coverage-thresholds.test.ts imported vitest.config.ts, which pulled the
config into tsconfig.tests.json's program; that program compiles as
CommonJS and rejects the config's import.meta, so typecheck:tests
failed. The test now loads the config at runtime. The other new gate
tests get prettier's formatting.
The client has had lint:size since #2612, the server had nothing, and
the server is where the biggest files live: maps.service.ts holds 3231
lines and grew by 200 in a month, and nine more services are past 1100.
scripts/size-lint.mjs carries the client's semantics over to src/ and
scripts/: a file may hold 1000 lines, the 23 that already hold more are
pinned at today's length in scripts/size-baseline.json, and --update
only ever lowers an entry.
A line past prettier's 120 columns counts once per 120 columns it spans,
so joining lines does not make room under the limit. The check fails
closed: a missing or malformed baseline or a missing src/ stops it
instead of passing with nothing checked.
