Adding e2e specs for the submission page found a defect in the page they were written for, which is what they were for.
One limiter counted page loads and submissions against the same twenty-per-quarter-hour allowance, so a sender working through a box of stock ran out after ten items — the exact person the feature exists for, and the exact case the limiter's own comment said must not be refused. The comment said refusing them costs a consignment while the number quietly did it.
Worse, the page could not tell a 429 from a 404. `fetchIntakeLink` treated any non-OK response as "no link", so a throttled sender was told "This link is not active" and sent to ask for a replacement — which could not have helped, because the problem was their address and a minute of patience. Two conditions needing opposite reactions were sharing a message.
Now two limiters, because the two requests cost different things. Reading a link hits one indexed row and writes nothing, so that allowance is generous at 120: someone re-reading the form or losing their signal should never be told to wait. Submitting writes up to six files, so that is the one worth bounding, at 30 — more than anyone photographing items can manage and far less than a script would want.
The page gains a third state. Unknown, revoked and used-up still collapse into one "not active" card, because whether a link exists is not something a stranger needs to learn. Throttled is deliberately kept apart from them, since "wait a moment" and "go and ask for another link" are opposite instructions.
Measured rather than assumed, on a freshly started process both times: before, 25 page loads produced 14 rejections; after, 40 produce none. The first attempt at that measurement was wrong and worth recording — the restart had failed with EADDRINUSE, so it read 30 of 30 against the old process's already-exhausted store.
The two specs now pass in a full parallel run alongside everything else. They are scoped the way #241 asks: unique run ids, assertions naming only this run's rows, nothing asserted about the table as a whole.
Backend: 284 integration, 309 unit. Frontend: build clean, lint unchanged at 2 pre-existing warnings.
Ref #222, #241
