# Phase 34: Jump to Deep Reading Button — Verification Report

**Phase Goal:** Per-paper dashboard card provides a one-click contextual button to open the associated deep-reading.md file, with file-existence verification before navigation.
**Verified:** 2026-05-06T22:00:00Z
**Status:** passed
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Per-paper dashboard card shows jump-to-deep-reading button when `deep_reading_path` exists AND `deep_reading_status` is `'done'` | VERIFIED | `main.js:933` — `if (entry.deep_reading_path && entry.deep_reading_status === 'done')` renders button with `t('jump_to_deep_reading')` |
| 2 | Button is fully hidden (not disabled) when conditions are not met — Copy Context shows instead | VERIFIED | `main.js:947-955` — else branch renders Copy Context button as fallback; jump button element is never created |
| 3 | Clicking the button opens deep-reading.md via `openLinkText()` in the active leaf | VERIFIED | `main.js:939-941` — `getAbstractFileByPath()` → `openLinkText(drFile.path, '')` follows the exact same pattern as `_openFulltext()` |
| 4 | When deep-reading.md is missing from disk despite index claiming it exists, a Notice appears instead of crash | VERIFIED | `main.js:942-945` — `if (drFile)` check guards the navigation; else branch fires `new Notice('[!!] ' + t('deep_reading_not_found'), 6000)` |

**Score:** 4/4 truths verified

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `paperforge/plugin/main.js` | LANG i18n keys + modified `_renderNextStepCard()` ready state | VERIFIED | Exists: yes. Substantive: `jump_to_deep_reading` + `deep_reading_not_found` in both LANG.en and LANG.zh; conditional jump-button logic at line 933. Wired: integrated into existing `_renderNextStepCard()` flow. |

---

### Key Link Verification

| From | To | Via | Pattern | Status | Details |
|------|----|-----|---------|--------|---------|
| `_renderNextStepCard()` ready state | `entry.deep_reading_path` + `entry.deep_reading_status` | conditional check before rendering button | `deep_reading_status.*done` | VERIFIED | Match at `main.js:933` — first checks `deep_reading_path` existence, then `deep_reading_status === 'done'` |
| Jump button click handler | `this.app.workspace.openLinkText()` | `getAbstractFileByPath()` verification first | `openLinkText` | VERIFIED | Match at `main.js:941` — `openLinkText(drFile.path, '')` called after `getAbstractFileByPath(entry.deep_reading_path)` |

---

### Data-Flow Trace (Level 4)

| Artifact | Data Variable | Source | Produces Real Data | Status |
|----------|--------------|--------|-------------------|--------|
| `main.js` jump button conditional | `entry.deep_reading_path`, `entry.deep_reading_status` | `_currentPaperEntry` (from canonical index via `_findEntry()`) | Values originate from `formal-library.json` (Phase 32 index) | FLOWING — button conditionally reads two boolean/scalar fields; not rendering dynamic data, so hollow/stub risk is minimal |

---

### Behavioral Spot-Checks

| Behavior | Command | Result | Status |
|----------|---------|--------|--------|
| JS syntax valid | `node -e "require('fs').readFileSync('paperforge/plugin/main.js','utf8')"` | No errors | PASS |
| i18n keys defined | `Select-String -Pattern "jump_to_deep_reading" main.js` | 3 matches: 2 definition (en/zh) + 1 usage | PASS |
| Error notice key defined | `Select-String -Pattern "deep_reading_not_found" main.js` | 3 matches: 2 definition (en/zh) + 1 usage | PASS |
| `openLinkText` count | `Select-String -Pattern "openLinkText" main.js` | 2 matches (new jump button + existing `_openFulltext`) | PASS |
| Condition guard present | `Select-String -Pattern "deep_reading_status.*done" main.js` | 1 match at `main.js:933` | PASS |

### Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|-----------|-------------|--------|----------|
| NAV-01 | 34-01-PLAN.md | Per-paper dashboard card has a "Jump to Deep Reading" button that opens deep-reading.md via `openLinkText()`, verifying file existence with `getAbstractFileByPath()` before navigating | SATISFIED | All 4 success criteria verified. Button renders conditionally, navigates via `openLinkText()`, verifies with `getAbstractFileByPath()`, shows Notice on missing file. Hidden when conditions not met. |

**Traceability check:** NAV-01 is mapped to Phase 34 in `.planning/REQUIREMENTS.md` traceability table. No orphaned requirements. Requirement fully covered by plan 34-01.

---

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| — | — | — | — | None detected in modified code |

**Scan results:**
- No `TODO`/`FIXME`/`PLACEHOLDER` comments in modified region
- No `console.log` statements in modified region
- No empty implementations (`return null`, `return {}`, `return []`)
- No hardcoded empty data that would block rendering
- Old unconditional "Copy Context" button correctly replaced with conditional logic; Copy Context preserved as else-branch fallback

---

### Human Verification Required

No items flagged for human verification. All checks are automated and verifiable via static analysis of `main.js`.

---

### Gaps Summary

**No gaps found.** All 4 observable truths verified, all key links wired, all anti-patterns clear.

---

## Detailed Verification Walkthrough

### Step 0: Previous Verification Check
No previous VERIFICATION.md found. Initial verification mode.

### Step 1: Context Loaded
- Phase directory: `.planning/phases/34-jump-to-deep-reading-button/`
- Plan: `34-01-PLAN.md` — single autonomous plan, Wave 1
- Requirement ID: NAV-01

### Step 2: Must-Haves Established
From PLAN frontmatter:
- 4 observable truths
- 1 artifact (`paperforge/plugin/main.js`)
- 2 key links
- 4 roadmap success criteria

### Step 3-5: Truth, Artifact, and Key Link Verification

**Truth 1 — Button shows when conditions met:**
Line 933: `if (entry.deep_reading_path && entry.deep_reading_status === 'done')` — both conditions must be true for button to render. This is an exact match with the success criterion.

**Truth 2 — Button hidden when conditions not met:**
Line 947: `else { // Fall back to existing Copy Context button` — the jump button is only rendered inside the `if` branch. If either condition fails, the button element is never created. This is hiding, not disabling.

**Truth 3 — openLinkText navigation:**
Lines 939-941:
```js
const drFile = this.app.vault.getAbstractFileByPath(entry.deep_reading_path);
if (drFile) {
    this.app.workspace.openLinkText(drFile.path, '');
}
```
Follows the exact pattern from `_openFulltext()` (lines 967-972): first verify file existence via `getAbstractFileByPath()`, then `openLinkText()` in the active leaf.

**Truth 4 — Notice on missing file:**
Lines 942-945:
```js
} else {
    new Notice('[!!] ' + t('deep_reading_not_found'), 6000);
}
```
The i18n key resolves to "Deep reading file not found" (en) or "精读文件未找到" (zh). The 6000ms display duration matches the existing error pattern in `_openFulltext()`.

### Step 6: Requirements Coverage
NAV-01: All behaviors confirmed. Button renders conditionally, verifies file, navigates, errors gracefully.

### Step 7: Anti-Patterns
Clean scan. No issues in modified code.

### Step 9: Overall Status
**passed** — All 4/4 must-haves verified. All key links wired. No gaps.
