An adversarial audit over the three merged migration PRs. Sixteen findings
survived triple refutation; these are the ones with a defect behind them.
The serious one is mine, from the gateway move. ws registers
`error: this.emit.bind(this, 'error')` on the http server it attaches to, and
the adapter now runs inside buildApp, before listen(). So from that moment the
http server HAS an error listener and Node stops throwing on one. The adapter's
handler was `() => {}`, which meant EADDRINUSE was forwarded there and dropped:
the process survived, the listen callback never ran, so the banner never
printed and the scheduler never started. A container that looks healthy and
serves nothing. Reproduced, then fixed at both ends: index.ts owns the fatal
decision on the http server, and the adapter logs instead of swallowing.
Four DTOs were tightening contracts rather than describing them, which is the
thing the pipe-before-handler ordering makes easy to do by accident:
- OauthClientCreateDto replaced 'Name is required' with a Zod field report, and
pre-empted the handler's 403 on an instance with the MCP addon off.
- BookingImportConfirmDto demanded per-item fields the service never reads, so
a caller assembling items itself got a 400 about `source`.
- TagCreateDto/TagUpdateDto typed name and color as strings; the legacy route
bound whatever arrived, so a numeric name used to create a tag.
- PluginUserSettingsUpdateDto typed config as a record, where the handler
answers 200 for anything it cannot use.
Two of my own tests were false-green, which the audit demonstrated by mutation
rather than by reading. WSGW-008 asserted on frames that never carry the user
object at all, so it passed with the password_version strip deleted; it reads
the retained identity now. GEO-009 made the same assertion before and after the
write; it distinguishes a cached negative from a miss now, through a hasCached
seam that says what getCached cannot. Both were re-run against the mutation
they exist to catch, and both fail on it.
booking-import geocodes every venue and endpoint in one request loop, up to
thirty sequential calls. Folding maps onto the shared Nominatim cursor put that
loop on the interactive lane, so an import starved every concurrent keystroke
for half a minute. It takes the background lane now, which is what the two-lane
split was built for.
Also: the README's in-container bridge list had outlived one entry and was
missing another, and the journey e2e still mocked a module this branch deleted.
