fix(runtime): mount GET /ready so the readiness probe is reachable over HTTP - #2227
Merged
Conversation
…er HTTP Seam #2 added the dispatcher's `/ready` handler (200 running / 503 booting or draining) but never mounted a route for it. The dispatcher mounts routes EXPLICITLY (no catch-all), so `GET /api/v1/ready` matched nothing and returned the Hono not-found 404 before reaching dispatch() — the exact failure mode that shipped `/mcp` and `/keys` broken, hidden because the unit test called dispatch() directly. Mount `${prefix}/ready` next to `${prefix}/health`. This is the contract the EE multi-node rolling-restart drain gate polls (cloud ADR-0018) so a load balancer stops routing to a replica before it closes. Tests: - dispatcher-plugin.routes.test.ts: assert both /health and /ready are mounted (registration-level guard that would have caught this). - dispatcher-plugin.ready.integration.test.ts (new): boot a real HonoServerPlugin + dispatcher on a socket, fetch /ready -> 200 (running) and 503 (draining via getState), and confirm a bogus path returns the prod {"error":"Not found"} 404 so the test reproduces the pre-fix failure rather than passing vacuously. Adds a test-only devDependency on @objectstack/plugin-hono-server. Verified: pnpm --filter @objectstack/runtime build (strict DTS), full runtime suite (420 tests), and a CLI boot+curl (/api/v1/ready 404 -> 200).

Problem
Seam #2 (PR #2217) added a
GET /readyreadiness handler inside the dispatcher'sdispatch()(next to/health) plus a passing unit test. But in a real running server/readyreturned 404 ({"error":"Not found"}) and was unreachable, while/api/v1/healthreturned 200.Root cause: the dispatcher mounts routes on the HTTP server explicitly — there is no catch-all.
${prefix}/healthis registered indispatcher-plugin.ts;${prefix}/readynever was. SoGET /api/v1/readymatched no route and fell through to HonoServerPlugin'snotFoundhandler before reachingdispatch(). This is the exact class of bug that shipped/mcpand/keysbroken — the unit test passed because it calleddispatch()directly.Fix
Mount
${prefix}/readynext to${prefix}/health, routing todispatch('GET', '/ready', …). The 200 (running) / 503 (booting or draining) handler logic was already correct and is untouched. This is the contract the EE multi-node rolling-restart drain gate polls (cloud ADR-0018) so a load balancer stops routing to a replica before it closes.Tests
