Second pass over the suite, driven by the inventory in the gaps document. Nine
agents wrote suites in parallel against private databases, then a tenth read all
of it adversarially and five of its findings were fixed.
unit + component 2076 -> 2079 (+888 over the round)
api 647 -> 1015
e2e 18 -> 29
What was closed:
- lib/route-access.ts, the page-level authorization layer, went from zero tests
to 48. Every API route was guarded and none of the pages were.
- The five media proxy routes now have a real 2xx beside every 403. The blocker
was the positive control, solved by stubbing r2Client.send() and leaving
lib/r2-media-proxy.ts itself real.
- Every remaining server-side lib module: invitations, email verification, the
upload tokens, the logger, request origin, the whole R2 and Bunny lifecycle,
notifications and admin stats.
- Six video-page hooks, and the chunking arithmetic extracted out of
lib/client/r2-video-upload.ts as a pure module.
- Five end-to-end flows: workspace members, bulk operations, the admin area,
player interaction and failure recovery.
Three things about the harness itself turned out to be wrong:
- Two @/lib/r2 stubs in tests/setup/api.ts had the wrong return shape, so every
route reaching finalizeR2VideoUpload silently took the "not a valid video"
branch and no test noticed.
- The auth matrix asserted only "not 2xx", which two entries satisfied without
their guard existing. It now requires 401 or 403, which makes both
load-bearing, and all 60 routes pass the stricter form.
- Both admin API routes had no positive control anywhere: replacing their guard
with an unconditional refusal left the entire suite green. Found by the
adversarial review, now covered.
Process:
- bun run test:mutation runs StrykerJS over the authorization and validation
modules. Diagnostic, not a gate, weekly in CI rather than on a push.
- playwright.config.ts gains an opt-in webkit project for the player spec.
- AGENTS.md now requires a batch of new tests to be reviewed by somebody who
did not write them.
Only two production files change, both deliberate: lib/auth.ts loses a verbatim
copy of its own permission formulas, and lib/client/r2-video-upload.ts calls the
extracted arithmetic. No behaviour change in either.
