understand our current codebase architecture and map it towards what we have in the UI side of things; we need to make sure the UI is fully functional and data we have is properly flowing. I also want you to write unit tests for the important functions and workflows of our app.

I'll start by understanding the codebase structure, then map the backend architecture to the UI to find gaps, and finally write unit tests. Let me kick off exploration.

We're in plan mode. Let me launch parallel exploration agents to understand the architecture, the UI, and existing test patterns.

Excellent, I have a thorough picture now. Let me verify a few critical claims directly — the test suite state, the OAuth 404 gap, and the langfuse import that allegedly blocks two test files.

Confirmed the key facts. Two test files (entity-resolution.test.ts, triple-extraction.test.ts) fail to load — vitest can't resolve @langfuse/otel pulled in transitively through the LLM gateway, so 21 tests pass but those two suites collect 0 tests. And the app/ tree confirms there is no /onboarding, /today, /relationships, or /search page — yet the OAuth callback redirects to /onboarding (a 404) and middleware gates routes that don't exist.

Let me read the key UI files directly to ground the plan.

Let me check the connector registry (for the connect UI) and confirm there's no "list connected sources" endpoint.

I now have a complete, verified picture. Let me record the architecture-to-UI map and findings in the plan file, then confirm scope with you.

Now let me confirm scope with you on the two decisions that materially change the work.

You chose the full UI build (onboarding, relationships, today, search) and pure + orchestration tests. The Today and Search screens need new backend endpoints, so let me have a Plan agent design the concrete implementation — reusing existing retrieval/DB seams — and pin down the test list.

The Plan agent produced a grounded, file-by-file design. Let me finalize the plan file with the concrete implementation.

The plan is complete and grounded. Here's the summary before I hand it over for approval.

What I found (architecture → UI map):

The backend answer plane works end-to-end (/api/answer → plan → hybrid_search → graph-expand → rollup → assemble → streamed cited synthesis), and ingestion is solid.
But the UI is a thin slice: a signed-in user can only use /ask. There is no UI to connect a data source, the OAuth callback redirects to /onboarding which is a 404, GET /api/graph is fully built but has no caller, and middleware gates /today//relationships//search pages that don't exist.
pnpm test: 21 pass, but 2 suites fail to load (entity-resolution, triple-extraction) — vitest can't resolve @langfuse/otel pulled in transitively.

What the plan does (your chosen scope: all screens + pure & orchestration tests):

Backend: GET /api/sources, GET /api/today, GET /api/search (via a new searchItems helper that reuses existing retrieval stages, no synthesis).
UI: shared nav in layout, real home shell, and the four screens — onboarding/sources (fixes the OAuth 404 and makes ingestion startable from the UI), relationships, today, search.
Middleware aligned to real pages.
Tests: fix the 2 broken suites with a hoisted langfuse mock, plus ~10 new pure-logic suites and 5 orchestration suites (answer-route branches, resolveEntity, the 3 new endpoints).

The full file-by-file detail with reuse seams and test cases is in the plan file.

Plan approved. Since this is a background job, let me isolate my work in a worktree, then set up task tracking and start implementing.

Worktree ready. Let me create the task list and read the key files I'll reuse.

Now let me read the remaining files needed for the endpoints and tests.

I have what I need for the backend. Let me start building. Marking task 1 in progress.

Now the three API routes:

Let me verify the generated DB types cover the columns I'm selecting.

Backend endpoints done. Moving to UI.

Now the home page:

Now the onboarding page:

Now the relationships page:

Now the today page:

Now the search page:

UI pages done. Now the middleware update:

Middleware done. Now fixing the broken test suites and writing tests. Let me read the test files and modules I'll need.

Now I understand the patterns. Let me fix the two broken suites with a hoisted langfuse mock.

Now let me read entity-resolution.ts, calendar.ts, linear.ts, session.ts, and supabase.ts before writing the remaining tests.

Let me check the session module for the UnauthorizedError export and getUserId signature, needed for route tests.

Now I'll write the entity-resolution test (langfuse mock + extend with resolveEntity orchestration tests using a mocked Supabase client).

Broken suites fixed. Now writing the new unit tests. Let me first check the vitest config for path alias support (the API routes use @/ imports).

@/ alias isn't configured for vitest, but the API route handlers use it — I need to add it so route tests resolve. Let me update the vitest config, then write all the test files.

Now the pure-logic tests:

Now the calendar and linear connector tests:

Now the orchestration route tests:

All tests written. Now let me run the full suite.

The worktree has no node_modules. Let me symlink it from the main checkout (same project, same lockfile).

Two fixes needed: the vi.mock factories reference a top-level class that's in the temporal dead zone during hoisting (use vi.hoisted), and the answer route needs @langfuse/tracing mocked too. Let me rewrite the four route tests.

All 21 suites pass (72 tests, 0 failures — up from 21 passing with 2 broken suites). The stderr lines are the expected console.error from the 500-path tests. Now typecheck:

These "cannot find module" errors are for packages I didn't touch (@sentry/nextjs, @langfuse/*, @opentelemetry/*) in files I didn't modify. Let me check whether this is pre-existing in the main checkout vs. a symlink artifact.

The @langfuse and @sentry directories don't exist at the top level of node_modules. Let me investigate the node_modules layout and confirm whether typecheck was already failing before my changes.

The main checkout's node_modules is incomplete — @langfuse/*, @sentry/*, @opentelemetry/*, ai, next, react were never fully installed (only 5 scoped packages present). That's why typecheck fails, and it's pre-existing — every file in the error list (instrumentation.ts, sentry.*.config.ts, langfuse.ts, trigger/ingest.ts, the unmodified answer/route.ts) is one I never touched. None of my new files appear.

Let me confirm my changes add zero new type errors, then attempt a full install to get a clean baseline.

My code is type-clean. Now let me attempt a full pnpm install so the baseline deps resolve and I can verify typecheck end-to-end.

Dependencies installed (the missing packages were reused from the pnpm store offline). Now re-run typecheck and the test suite:
