feat: let a customer resend their own verification email (#110)
A verification email was sent once, at registration. If it was lost, filtered, or arrived after the 24-hour token had expired, the customer had no route back except registering again with a different address. POST /api/customers/resend-verification mints a fresh token and sends the mail, and the account page grows a "Send it again" button beside the warning that was already there. The button only exists while the address is unverified: on a verified account it would be a control whose only outcome is a refusal, and the endpoint refuses that case rather than sending a pointless email. The mint-token-and-send sequence now lives in one place. Registration and the email change already did the same three steps - supersede any outstanding token, mint a new one, send it - and this would have been a third copy. The step most likely to be dropped in a copy is the supersede, and it is the one that matters: without it an older message still sitting in the inbox goes on verifying. Anything that makes the server send mail on request is an abuse vector, so this is rate limited to three an hour, keyed on the customer id. That is tighter than either existing limiter and sidesteps #84's IPv6 problem entirely, since a signed-in caller has an identity better than an address to count against and cannot escape the bucket by moving within a delegated prefix. The refusal says the mail probably did send and to check the spam folder, which is both more useful and more honest than a bare 429. The claim that keying on customer id also solved test isolation was wrong, and the tests caught it. resetDb truncates with RESTART IDENTITY, so every integration test's first customer is id 1: three tests that each sent once left the fourth starting at its limit, and two tests failed on a 429 they never asked for. A "fresh customer per test" is a fresh row with a recycled identity. The limiter now has an explicit exported store the suite clears between tests, and the comment that claimed otherwise has been corrected rather than left to mislead the next reader. Verification: seven integration tests covering the unauthenticated refusal, the send, the new token invalidating the old one - asserted through the endpoint that would honour the stale link rather than by counting rows - the new link actually verifying, the already-verified refusal, the allowance stopping the fourth send rather than merely reporting it, and one customer's exhausted allowance leaving another's intact. Three end-to-end tests for the button, its confirmation and the message on the fourth click. The 33 integration tests across the three suites this touched all pass, as do the 199 backend unit tests. tsc clean on both sides, ESLint no errors.

fix(backend): stop IPv6 callers bypassing the password-reset rate limit (#84)
The QA stack has been logging ERR_ERL_KEY_GEN_IPV6 at every boot, and express-rate-limit was right to complain. keyByCallerAndEmail built its key from req.ip raw. For an IPv4 caller that is one address and the limiter worked as intended. For an IPv6 caller it is the full 128 bits — and a residential IPv6 customer is delegated an entire prefix and can source every request from a different address inside it at no cost. Keyed that way, each request counted as a new caller and the allowance of five per fifteen minutes never bound at all. That matters more here than it would elsewhere, because of what this limiter is for. Its own comment says it: without one, anyone can make the server send unlimited mail to any address they choose. For IPv6 clients there effectively was no limiter, while the code read as though there were. The caller half of the key now goes through express-rate-limit's ipKeyGenerator, which groups IPv6 by prefix and returns IPv4 unchanged. The helper's default is /56 rather than /64, and that default is kept deliberately: /56 covers a whole delegated site, so an attacker cannot escape their bucket by moving within their own allocation. It does mean several households behind one delegation share an allowance — acceptable only because the key also carries the email address, so they collide just when targeting the same account. The reasoning sits next to the code, because a future reader tightening it to /64 would silently reopen the hole. keyByCallerAndEmail is now exported so it can be tested directly. The limiter's allowance is still not asserted anywhere, and should not be: its store is process-wide, so a test that exhausts it leaks into every later test from the same address and fails something unrelated later. The key function is pure, and it is where the bug was. Verified by firing the guard rather than reasoning about it: building main and loading the module reproduces the ValidationError, and the same load with this change is silent. Seven new unit tests cover an IPv4 caller unchanged, two addresses in one delegation collapsing to a single key, separate delegations staying apart, an IPv4-mapped address keying the same as the plain IPv4 one, email normalisation, a non-string email, and a request with no address at all. 86 unit tests pass, 144 integration, lint 0 errors and 8 warnings — unchanged.

feat(backend): log client-side render errors to the server (#62)
The frontend's error boundaries need somewhere to report to. A boundary that only shows a customer a message leaves nobody knowing it happened, which is the failure shape this project has designed against three times already. POST /api/client-errors takes a report, truncates its fields, logs it with a [client-error] prefix and returns 204. No storage: the container log is where this project's operational visibility already lives, and a table with a retention policy and an admin screen is a subsystem larger than the issue. An unrecognised context is a 400 rather than a log line under a guessed label, following parseItemFilters, which refuses a malformed filter instead of coercing it. Oversized fields go the other way and are truncated rather than refused, because an over-long report is still the only record of the failure. The endpoint gets its own rate limiter rather than reusing passwordResetRequestLimiter, whose comment already warns that its caller-and-email key collapses every caller into one shared bucket on an endpoint without an email. The new one takes the default key generator, which also avoids the ERR_ERL_KEY_GEN_IPV6 warning the custom key produces. Verified: 138 integration tests pass, 4 of them new, and 79 unit. The unit count rose by one without a test being written — routesAreWrapped.test.ts runs describe.each over the files in src/routes, so a new route file generates a case. The handler is synchronous and needs no asyncRoute wrapper. Refs #62 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

feat: customer password reset via email round-trip (#32)
Adds "Forgot password?" to the login page, a request page, and a reset page reached by a one-hour, single-use token delivered by email. Reuses customer_tokens with a new password_reset kind alongside verify_email. The request endpoint always answers 200, whether or not the address has an account, so it cannot be used to test addresses for membership. Note /register still reveals existence through its 409 on a duplicate, so this protection is currently partial; closing that is its own change. Completing a reset deletes every session for that customer. A reset prompted by a compromise has to evict the intruder, and leaving a 30-day cookie alive would defeat the point. It also marks the address verified, since receiving the mail is exactly what verification proves, and supersedes any outstanding token so an older link in the inbox cannot be resurrected. Introduces the first rate limiting in the codebase, on the request endpoint only. The limiter is keyed on caller *and* submitted address: keying on IP alone would let one person lock out everyone behind the same proxy, and everything arrives via Nginx Proxy Manager. Applying that same limiter to the reset endpoint, which carries no address, collapsed every caller into one shared bucket -- so that endpoint is deliberately unlimited instead, protected by a 32-byte single-use token whose bcrypt work only runs after the token matches. The e2e tests read the issued token directly from Postgres rather than through a test-support endpoint. An endpoint returning a reset token for an arbitrary address is account takeover for every customer if it is ever reachable, and an environment gate is thin protection against that.
