A 15-agent audit of the merged tree confirmed 9 envelope/contract bugs;
all fixed here, with live-server contract tests added:
Blockers (fresh-install quick start broken):
- session-ui.js runClaude/runShell unwrapped .data from the /api/cases/:name
404 error envelope (which has no data key), so a not-yet-created case threw
TypeError instead of triggering the auto-create fallback. Now '?.data ?? {}'.
Contract violations on the new stable surface:
- Unknown /api routes returned HTTP 404 with {success:true,...} (Fastify's
default not-found payload was wrapped by the envelope hook). Added a
setNotFoundHandler returning the standard error envelope for /api paths.
- POST /api/events/subscribe 400 body became {success:true,data:{error}};
now createErrorResponse(INVALID_INPUT).
- POST /api/clipboard validation error lacked errorCode and shipped HTTP 200;
now createErrorResponse(INVALID_INPUT) -> 400.
- POST /api/run catch path returned bare {success:false,sessionId,error}
(HTTP 200, no errorCode); now OPERATION_FAILED envelope -> 422 with the
dead session id in the message.
- DELETE tail-file/:streamId returned {success: closed}, colliding with the
envelope discriminator; now returns {closed}.
Dead/regressed UI paths:
- Plan history modal could never open: route returned the bare history array
under data while the frontend read data.data.history/currentVersion. Route
now returns {history, currentVersion}; modal task count fixed to stats.total.
- Self-update error toast read j.error.message from the string-typed envelope
error, always falling back to the generic message; now reads the string.
Cleanup:
- Removed the stale QuickStartResponse type (unreferenced; documented the
pre-envelope shape and invited success-key collisions).
Tests: new test/http-contract.test.ts boots a real WebServer (port 3168) and
pins the envelope, /api/v1 alias, error statuses, and the /api 404 shape —
the route-test harness does not install the server-level hook, so these need
the live server. Updated file-routes/plan-routes/scheduled-runs tests to the
fixed shapes.
