Summary

  • Makes Affected cards, Planned changes, and Technical details (provenance/triage run IDs) collapsible in ReviewView, collapsed by default to reduce visual overload
  • Color-codes risk levels using existing design tokens: Low=green, Medium=amber, High/Critical=red, with text labels preserved for accessibility
  • Consolidates provenance link buttons (Open Capture, Review Link, Open Board) into a dropdown menu
  • Shows affected cards as a count badge on the collapsed section header

Test plan

  • npm run typecheck passes
  • npm run build succeeds
  • All 1444 vitest unit tests pass (including 25 ReviewView tests updated for collapse behavior)
  • Manual: verify collapse/expand toggles work for all three sections
  • Manual: verify risk badge colors render correctly for Low/Medium/High/Critical
  • Manual: verify Links dropdown opens and navigates correctly
  • Manual: verify action buttons (Approve, Reject, Apply) remain accessible outside collapsed sections

Closes #626

- Make Affected cards, Planned changes, and Technical details sections
  collapsible (collapsed by default) to reduce visual overload
- Color-code risk levels: Low=green, Medium=amber, High/Critical=red
  using existing design tokens, with text labels for accessibility
- Hide triage run IDs under Technical details toggle
- Consolidate provenance link buttons (Open Capture, Review Link,
  Open Board) into a Links dropdown menu
- Show affected cards as count badge on collapsed toggle header
- Update tests to expand sections before asserting collapsed content

Self-review of #641

What works well

  • Collapsible sections reduce visual overload as intended; collapsed-by-default is the right default
  • Risk badge color-coding uses existing design tokens so it stays consistent with the theme
  • Text labels ("Low risk", "Medium risk") accompany color, so the UI is not color-only (accessibility)
  • aria-expanded on all toggles gives screen readers proper state info
  • Count badges on collapsed headers give a quick glance at section content
  • All 1444 unit tests pass including the 3 updated ReviewView tests

Potential concerns reviewed

  1. Links dropdown blur behavior: The @blur on the Links button closes the dropdown via closeLinkDropdown. The @mousedown.prevent on dropdown items prevents blur from firing before the click/navigation. This is a standard pattern and should work.
  2. Reactivity of expandedSections: Uses { ...expandedSections.value } spread to trigger Vue reactivity after mutating internal Sets. This works but is slightly unconventional -- a future refactor could switch to a simpler Record<string, string[]> for clarity.
  3. Removed sourceCue/riskCue display: The source type is still shown in the always-visible meta line ("Source: Queue"). The risk cue text is replaced by the color-coded badge. The raw presentation.sourceCue and presentation.riskCue strings are no longer rendered -- this is intentional to reduce noise, but some users may miss the detailed risk cue text. Acceptable tradeoff for the card density improvement.
  4. No "Open Board" outside dropdown: Previously "Open Board" was a top-level button in the provenance section. Now it is inside the Links dropdown under Technical details. For proposals without provenance context, "Open Board" is not shown at all (same as before). Acceptable since the board is still reachable from the header board filter.
  5. Mobile responsive: Dropdown switches to static positioning on small screens to avoid overflow issues.

Verdict

No blocking issues found. The implementation matches the issue requirements.

Code Review

This pull request refactors the ReviewView component to introduce collapsible sections for proposal details and a new color-coded risk badge system. Feedback focuses on improving keyboard accessibility for the links dropdown, adopting more idiomatic Vue 3 reactivity for managing expanded states, and simplifying the risk level class logic. Additionally, it is recommended to hide decorative icons from screen readers to ensure a better experience for users with assistive technologies.

The current closeLinkDropdown implementation, when paired with @blur on the trigger button, breaks keyboard accessibility. When a user tabs from the button into the dropdown menu, the blur event fires and closes the menu before the focus can reach the links inside.

Updating the logic to check relatedTarget ensures the dropdown only closes if focus actually leaves the dropdown component area, allowing keyboard users to navigate the menu items.

function closeLinkDropdown(event: FocusEvent) {
  const nextFocus = event.relatedTarget as HTMLElement
  if (nextFocus?.closest('.td-review-card__links-dropdown-wrapper')) {
    return
  }
  openLinkDropdown.value = null

The current implementation of expandedSections using a Record of Sets requires manual reactivity triggering via object spreading ({ ...expandedSections.value }) because Vue's reactivity system does not automatically track internal mutations of a Set unless the Set itself is made reactive.

In Vue 3, it is more idiomatic and efficient to use a nested reactive object. Since ref on an object is deep, mutations to nested properties (like expandedSections.value[id][section]) will be tracked automatically, avoiding the need to recreate the entire state object on every toggle.

const expandedSections = ref<Record<string, Record<string, boolean>>>({})

function isSectionExpanded(proposalId: string, section: string): boolean {
  return !!expandedSections.value[proposalId]?.[section]
}

function toggleSection(proposalId: string, section: string) {
  if (!expandedSections.value[proposalId]) {
    expandedSections.value[proposalId] = {}
  }
  expandedSections.value[proposalId][section] = !expandedSections.value[proposalId][section]
}

This function can be simplified by using a mapping object instead of multiple if statements. This improves readability and makes the code easier to maintain if more risk levels are added in the future.

function riskLevelClass(riskLevel: ApiProposal['riskLevel']): string {
  const riskClasses: Record<string, string> = {
    Low: 'td-risk--low',
    Medium: 'td-risk--medium',
    High: 'td-risk--high',
    Critical: 'td-risk--critical',
  }
  return riskClasses[normalizeProposalRiskLevel(riskLevel)] ?? 'td-risk--low'
}

The decorative collapse icon should be hidden from screen readers using aria-hidden="true" to avoid redundant announcements, as the parent button already provides a descriptive label and an aria-expanded state. This applies to all three collapsible sections in this view.

<span class="td-review-card__collapse-icon" :class="{ 'td-review-card__collapse-icon--open': isSectionExpanded(proposal.id, 'entities') }" aria-hidden="true">&#9654;</span>

Adversarial Code Review -- PR #641

CRITICAL: E2E test will break

Severity: Critical | File: tests/e2e/first-run.spec.ts, line 142

await proposalCard.getByRole('button', { name: 'Open Board' }).click()

The E2E test expects "Open Board" to be a directly visible button on the proposal card. After this PR, that button is buried two levels deep: first inside a collapsed "Technical details" section, then inside a "Links" dropdown. This test will fail because Playwright cannot find a hidden element with getByRole. The E2E test was not updated.


HIGH: Dropdown close-on-blur is fragile and racy

Severity: High | File: ReviewView.vue, lines 792-797

The Links dropdown uses @blur on the trigger button to call closeLinkDropdown(). This is unreliable:

  1. Race with mousedown: The dropdown items use @mousedown.prevent to prevent the blur from firing before the click, which is correct -- but router-link elements navigate on click, not mousedown. If the blur fires before the router-link's click handler processes, the dropdown will close and the link will vanish before navigation. The @mousedown.prevent only prevents default browser behavior (focus shift), it does not prevent the blur from firing on some browsers/timing.

  2. Keyboard navigation: There is no keyboard handling on the dropdown. A user who tabs into the dropdown menu items will cause the trigger button to blur, closing the dropdown. The role="menu" implies keyboard arrow-key navigation per WAI-ARIA menu pattern, but none is implemented.

  3. No click-outside handler: Clicking anywhere else in the page (not on a dropdown item) won't close the dropdown because @blur only fires when the button loses focus. Clicking a blank area of the page that isn't focusable won't trigger blur on the button.


HIGH: Missing aria-controls on collapsible sections

Severity: High | File: ReviewView.vue, lines 725-733, 747-755, 769-778

The collapse toggle buttons have aria-expanded but lack aria-controls pointing to the ID of the controlled panel. The WAI-ARIA disclosure pattern requires both attributes for screen readers to establish the relationship between trigger and content. The expanded content panels don't have id attributes at all.


MEDIUM: expandedSections state grows without cleanup

Severity: Medium | File: ReviewView.vue, lines 48-67

expandedSections is a ref<Record<string, Set<string>>> keyed by proposal ID. When proposals are dismissed, filtered out, or replaced by loadProposals(), their entries in expandedSections are never removed. Over a long session with many proposals, this accumulates stale entries. The Set objects inside are also not reactive themselves -- the code works around this by spreading ({ ...expandedSections.value }) on every toggle, which creates a new top-level object each time. This isn't a leak per se, but it's wasteful and fragile.


MEDIUM: riskCue and sourceCue removed from display but still in types

Severity: Medium | File: types/automation.ts, lines 30-31

The ProposalPresentation interface still declares riskCue: string and sourceCue: string as required fields. The test fixture data still populates them (spec lines 88-89, 558-559). While this isn't a runtime error (the backend still sends them), it's dead data -- the UI no longer displays riskCue or sourceCue from the presentation object anywhere. This is misleading for future contributors who might assume these fields are consumed.


MEDIUM: Test coverage dropped for "Open Board" and source/risk cue display

Severity: Medium | File: ReviewView.spec.ts, line 590

The "renders readable presentation cues and board follow-through actions" test previously asserted:

  • wrapper.text()).toContain('Created from an automation chat session.') (sourceCue)
  • wrapper.text()).toContain('Open Board') (board follow-through)

Both assertions were removed. There is now zero test coverage for:

  1. The "Open Board" button inside the Links dropdown
  2. Whether the Links dropdown renders all three items (Open Capture, Review Link, Open Board)
  3. Whether the dropdown closes after clicking an item

LOW: role="menu" used without full menu keyboard pattern

Severity: Low | File: ReviewView.vue, lines 800-829

The dropdown has role="menu" and items have role="menuitem", but the WAI-ARIA menu pattern requires arrow-key navigation between items, Home/End support, and Escape to close. None of these are implemented. Using role="menu" without the keyboard behavior is worse than using no role, because screen readers will announce it as a menu and users will expect the keyboard contract. Consider using role="listbox" or no role at all if full menu keyboard support isn't planned.


LOW: Duplicate summary display

Severity: Low | File: ReviewView.vue

The readableSummary(proposal) text appears as both the card <h2> title (line 704) and was previously also in a <p class="td-review-card__summary">. The old duplicate <p> was removed (good), but the .td-review-card__summary CSS class was also removed. Verify no other component references this class.


Summary

Severity Count
Critical 1 (E2E breakage)
High 2 (dropdown behavior, missing aria-controls)
Medium 3 (stale state, dead types, dropped test coverage)
Low 2 (menu pattern, duplicate removal)

The critical E2E breakage at first-run.spec.ts:142 must be fixed before merge. The dropdown @blur close mechanism needs a more robust approach (e.g., a click-outside directive or focus-within CSS check). The accessibility gaps (missing aria-controls, incomplete menu keyboard pattern) should be addressed to avoid regression against accessibility standards.

Address Gemini review findings:
- Replace Set-based expandedSections with Record<bool> for proper
  Vue reactivity tracking without manual object spreading
- Fix dropdown @blur to check relatedTarget so keyboard users can
  tab into the dropdown menu without it closing
- Add aria-hidden="true" to decorative collapse icons
The "Open Board" button moved inside a collapsed Technical details
section and Links dropdown. Update first-run E2E to expand section
and dropdown before clicking.
