A test fails when a new /api/v1 route is registered without an OpenAPI row #5134

Merged

I added `test/openapi-coverage.test.ts`. It fails, naming each route, when a registered `/api/v1` route has no row in `ROUTES` and isn't on the not-yet-described list. The new test file passes. I didn't get a type check: `tsc` couldn't find the `bun` type definitions here, so only `bun test` ran on this file.

What it reads: every router.add("METHOD", "/api/v1/…") in src/http/api.ts, including calls where the arguments sit on following lines. :param and *param are normalised to {} and compared with ROUTES, also normalised.
The list: NOT_YET_DESCRIBED holds today's 99 missing routes, one per line and sorted, with a comment that it only shrinks. That is more than the roughly 90 the issue estimated.
Parallel OpenAPI work: an entry that has since been described is ignored rather than failing, so OpenAPI issues landing in parallel stay green. The test prints how many entries could be removed (0 today).
Extra test: a second test fails if the list is unsorted or names a route that isn't registered, so stale entries can't linger.
The gate: scripts/gate.ts picks up every test/*.test.ts automatically, so I didn't edit it.

I did not describe any of the 99 routes; that is the follow-up work the list tracks.

To try it, run bun test test/openapi-coverage.test.ts. To see it fail, register a route in src/http/api.ts without a ROUTES row.

Closes #5117

The guard is useful and the 99-entry list is tidy, but it does not guard what its name says: a new /api/v1 route can still be registered without an OpenAPI row and the test stays green.

First fix: registered() only reads src/http/api.ts, and only calls whose path is a plain string literal. Missed today: 12 /api/v1 routes in src/http/feed.ts (feed, feed/chips, asks, asks/bulk, asks/decide, ...), 1 in src/http/passport_edge.ts, and the 14 api.ts routes built from a template literal such as ${BROWSE}/branches. Scan every file under src/http that calls router.add, and resolve the literal prefixes (BROWSE, and any like it) before normalising, or fail loudly when a router.add call in the scanned files has a path the regex cannot read. A count check that compares regex matches against the number of router.add( occurrences would catch both gaps. Then add the newly visible routes to NOT_YET_DESCRIBED, or describe them.

Second: expect(all.length).toBeGreaterThan(100) is a weak floor. Use the exact count check above so a changed call style cannot silently shrink coverage.

The author also says no type check ran (tsc could not find bun types); please run bun x tsc --noEmit after bun install.

No user-facing surface changes, so the tty, README and preview checks do not apply. Nothing here touches the arm-stability work, and the pull stays test-only, which is right.

The test in test/openapi-coverage.test.ts now covers routes it used to miss, and it throws if it can't read a router.add call. The new test file passes and bun x tsc --noEmit is clean after bun install. I did not run the whole check, which the forge runs.

Every route file: it scans every file under src/http that calls router.add. That adds the routes in feed.ts and passport_edge.ts, plus api.ts paths built with ${BROWSE} or with the kind loop (${kind} expands to issues and pulls). It also expands the method loop (PUT and DELETE) for the milestone watch route.
Loud on unreadable calls: for each file it requires the number of readable router.add( calls to equal the number of occurrences. It also throws when an /api/v1 path still contains an unresolved ${…}. That replaces the old > 100 floor, so a changed call style can no longer shrink coverage quietly.
The list: NOT_YET_DESCRIBED grows from 99 to 132 entries, all of them newly visible routes, still sorted. I did not describe them. A second test fails if the list is unsorted or names a route that isn't registered.

The kind and method expansions are hard-coded in the test. If a new loop appears, the test throws at that call instead of skipping it.

Test-only, does what #5117 asked, and addresses the earlier round. I rebuilt the scanner from the diff and ran it against the current tree: it reads every router.add( in all four route files under src/http (api, feed, passport_edge, server), and the read count matches the call count in each one. It resolves ${BROWSE}, and the kind loop (api.ts:6289, issues/pulls) and method loop (api.ts:3626, PUT/DELETE) expand to what the source does. It finds 270 routes. 131 have no row against main today. Main gained rows in #5051 since this branch's base, so one list entry is now described: this test ignores it, and it can be deleted later. No /api/v1 route is registered outside src/http (mcp/oauth/passport/feed helpers all live there and all register via router.add), so the scan scope is complete. A new route with no row fails with its name; an unreadable call style throws instead of quietly reducing coverage; stale or unsorted list entries fail the second test. No security surface, no runtime change, no dependency. The tty, README and preview checks don't apply. One small non-blocking note is inline.
