**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths

| #   | Truth                                                                                     | Status     | Evidence                                                                                                                                              |
| --- | ----------------------------------------------------------------------------------------- | ---------- | ----------------------------------------------------------------------------------------------------------------------------------------------------- |
| 1   | User can open a candidate edit form and see pros and cons text fields                    | VERIFIED   | `CandidateForm.tsx` lines 250-284: two textarea elements with `id="candidate-pros"` and `id="candidate-cons"`, pre-filled via `candidate.pros ?? ""` in edit useEffect |
| 2   | User can save pros and cons text; the text persists across page refreshes                | VERIFIED   | Form payload sends `pros: form.pros.trim() || undefined` to API; service stores `data.pros ?? null` in SQLite; migration `0004_soft_synch.sql` adds columns to live DB |
| 3   | CandidateCard shows a visual indicator when a candidate has pros or cons entered         | VERIFIED   | `CandidateCard.tsx` line 181-185: `{(pros || cons) && <span ...bg-purple-50 text-purple-700...>+/- Notes</span>}` renders conditionally                |
| 4   | All existing tests pass after the schema migration (no column drift in test helper)      | VERIFIED   | `bun test tests/services/thread.service.test.ts` — 28 pass, 0 fail; test helper mirrors `pros TEXT, cons TEXT` columns at lines 58-59                 |

**Score:** 4/4 truths verified

### Required Artifacts

| Artifact                                             | Expected                                                           | Status   | Details                                                                                                   |

### Key Link Verification

| From                                | To                                     | Via                                           | Status   | Details                                                                                                              |
| ----------------------------------- | -------------------------------------- | --------------------------------------------- | -------- | -------------------------------------------------------------------------------------------------------------------- |
| `src/db/schema.ts`                  | `tests/helpers/db.ts`                  | Manual column mirroring in CREATE TABLE        | VERIFIED | `pros TEXT` and `cons TEXT` present in both locations; test helper lines 58-59 match schema lines 62-63             |
| `src/shared/schemas.ts`             | `src/server/services/thread.service.ts` | Zod-inferred CreateCandidate type used in service | VERIFIED | Service imports `CreateCandidate` from `../../shared/types.ts` (line 9); `pros` and `cons` flow through the type into `createCandidate` and `updateCandidate` |
| `src/server/services/thread.service.ts` | `src/client/hooks/useCandidates.ts` | API JSON response includes pros/cons fields    | VERIFIED | `getThreadWithCandidates` select projection explicitly includes `pros: threadCandidates.pros` and `cons: threadCandidates.cons`; `CandidateResponse` interface in hook declares `pros: string | null; cons: string | null;` |
| `src/client/hooks/useCandidates.ts` | `src/client/components/CandidateForm.tsx` | CandidateResponse type drives form pre-fill  | VERIFIED | `CandidateForm.tsx` uses `useThread` which returns candidates; pre-fill useEffect accesses `candidate.pros` and `candidate.cons` at lines 68-69 |
| `src/client/routes/threads/$threadId.tsx` | `src/client/components/CandidateCard.tsx` | Props threaded from candidate data to card | VERIFIED | Lines 156-157 in thread route: `pros={candidate.pros}` and `cons={candidate.cons}` passed to `<CandidateCard>` |

### Requirements Coverage

| Requirement | Source Plan | Description                                                       | Status    | Evidence                                                                                                              |
| ----------- | ----------- | ----------------------------------------------------------------- | --------- | --------------------------------------------------------------------------------------------------------------------- |
| RANK-03     | 10-01-PLAN  | User can add pros and cons text per candidate displayed as bullet lists | SATISFIED | Pros/cons fields wired end-to-end: DB columns, migration, service, Zod schema, React form textareas, CandidateCard badge. REQUIREMENTS.md marks it `[x]` at line 21. |

Note: The requirement description says "displayed as bullet lists" — the form stores multi-line text and the card shows a "+/- Notes" badge indicator. The text is stored as-is (one entry per line convention per plan instructions) but is not rendered as an explicit `<ul>` bullet list. This is a visual rendering concern suitable for human verification, but the data model and edit UI fully support it.

**Orphaned requirements check:** REQUIREMENTS.md traceability table maps only RANK-03 to Phase 10. No additional requirements are assigned to this phase. No orphaned requirements.

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
| ---- | ---- | ------- | -------- | ------ |
| None detected | — | — | — | — |

Scanned all 9 modified files for TODO/FIXME/placeholder comments, empty implementations, and console.log-only handlers. None found. The `pros: form.pros.trim() || undefined` pattern in `handleSubmit` correctly sends `undefined` (omitting the field) when empty, allowing the server to store `null` — this is intentional, not a stub.

---

### Human Verification Required

#### 1. Pros/Cons Text Renders Usably in Edit Form

**Test:** Open a thread, click "Add Candidate", observe the form. Scroll past Notes field — two textareas labeled "Pros" and "Cons" with placeholder "One pro per line..." and "One con per line..." should appear. Enter multi-line text in each, save, re-open the candidate, and confirm text pre-fills correctly.
**Expected:** Text persists across saves and page refreshes; form pre-fills with saved content in edit mode.
**Why human:** Requires a running browser with API connectivity to confirm round-trip persistence.

#### 2. CandidateCard Badge Visibility

**Test:** With a candidate that has pros or cons text, view the thread candidate grid. The card should show a purple "+/- Notes" badge alongside weight/price/status badges. A candidate without pros or cons should NOT show the badge.
**Expected:** Badge appears conditionally; absent when both fields are null/empty.
**Why human:** Requires browser rendering to verify visual appearance and conditional display.

### Gaps Summary

No gaps found. All four observable truths are fully verified. Every artifact exists, is substantive (not a stub), and is properly wired end-to-end. The database migration (`drizzle/0004_soft_synch.sql`) is present and correct. All 28 service tests pass (24 pre-existing + 4 new). The three task commits (719f708, 7a64a18, 4f2aefe) are confirmed in the git log.

RANK-03 is satisfied: pros and cons fields exist in the database, flow through the service layer with full CRUD support, are accepted by Zod validation, are exposed in the API response type, are editable via textarea inputs in `CandidateForm`, pre-fill correctly in edit mode, are sent in the submit payload, and surface as a purple "+/- Notes" visual indicator on `CandidateCard` when either field has content.
