feat(dashboard): Command Center redesign (mission-control DNA)

[OneStepAt4time]

Aegis version

Developed with: v0.6.7

Vision

Redesign the dashboard as a command center for an agent fleet — not a SaaS dashboard. DNA: mission-control (deep-space navy, amber telemetry, cyan health, monospace data, alert hierarchy) + Linear-grade craft (Inter 510, negative letter-spacing, keyboard-first density). Bold + on-brand (aegis = shield/control) → distinctive, not another Linear clone.

Contract: `dashboard/DESIGN.md` (the source of truth every slice reads).

How it's built

Driven via aegis — each slice is a Claude Code session (acceptEdits) spawned through the Aegis API, reading DESIGN.md as the contract, then verified + committed. Dogfooding aegis to redesign aegis.

Slices (DRAFT — in progress)

• 1. Tokens + Inter — `@theme` → navy/amber/cyan palette; DM Sans → Inter (cv01/ss03/cv11). Foundation.
• 2. Status system — centralized `utils/statusStyles.ts` (single source for status→color); StatusDot + StallBadge migrated. 41-test suite.
• 3. Mono-for-values — every numeric reading (tokens/ms/cost/IDs/timestamps) → JetBrains Mono.
• 4. KPI/telemetry cards — MetricCard(s) + KPIBanner → uppercase label / big mono value / cyan delta.
• 5. Data tables — SessionTable/VirtualizedSessionList → dividers, active-row amber bar, dense.
• 6. Command palette + app shell — sidebar/header/⌘K → console aesthetic; brand mark.
• 7. Session detail — transcript/terminal chrome, approval toast, send composer.
• 8. Page pass — remaining pages to tokens, cut noise.
• 9. Cuts + polish — remove dead UI, focus rings, a11y/contrast audit.

Marking draft until slices 5-7 land (enough to evaluate the transformation). Each slice: tsc clean, build passes, green CI.

"## 🔄 Changes Requested — CI Failures (dashboard E2E)\n\nPR: feat(dashboard): Command Center redesign (mission-control DNA)\nAuthor: OneStepAt4time (Hephaestus via aegis-driven CC session)\nSlices landed: 1–4 of 10 (tokens, status system, mono sweep, KPI cards)\nStatus: Draft — slices 5–7 pending\n\n---\n\n### CI Status: ❌ FAILING\n\ntest (ubuntu-latest, 20) — dashboard E2E tests FAILED (run 28318792684)\n\nAll other checks green: lint ✅, test (ubuntu-22) ✅, CodeQL ✅, Trivy ✅, Gitleaks ✅, GitGuardian ✅, sdk-drift ✅, lint-pr-title ✅.\n\n---\n\n### Failure Breakdown (3 distinct root causes)\n\n#### 1. MetricCards mobile-responsive tests — 4 failures\nAll 4 tests fail because they look for .card-glass class via closest(), which no longer exists after the KPI card restyle (slice 4).\n\n- Delivery Rate card uses flex-col on mobile... — expected null not to be null\n- Delivery Rate card uses responsive padding — same\n- Delivery Rate text content is centered on mobile... — Cannot read properties of null (reading querySelector)\n- RingGauge renders inside the delivery rate card — same\n\nRoot cause: Slice 4 replaced the old card structure with the Command Center KPI pattern (new surface/border/padding classes). The test selectors are coupled to the old DOM structure (.card-glass).\n\nFix needed: Update src/__tests__/MetricCards.mobile-responsive.test.tsx to match the new card DOM structure, OR add a stable data-testid to the KPI cards and query via that instead of class-based traversal.\n\n#### 2. a11y-css focus ring test — 1 failure\nsrc/__tests__/a11y-css.test.ts — applies focus ring via :focus-visible\n\n- Expected: CSS contains box-shadow: var(--focus-ring-offset), var(--focus-ring)\n- Actual: CSS now starts with @import \"tailwindcss\"; (the file was rewritten in slice 1)\n\nRoot cause: Slice 1 rewrote src/index.css with the new @theme palette but did not preserve the focus ring CSS custom properties that the a11y test asserts.\n\nFix needed: Add the focus ring tokens back to src/index.css:\ncss\n--focus-ring: 0 0 0 2px var(--color-accent);\n--focus-ring-offset: 0 0 0 2px var(--color-void);\n\nAnd ensure the :focus-visible rule is present.\n\n#### 3. CostPage E2E test — text fragmentation (mono-for-values sweep)\nUnable to find an element with the text: Total: $1.25\n\nThe test does screen.getByText(\"Total: $1.25\") but the DOM now has:\nhtml\n<span>Total: <span class=\"font-mono\">$1.25</span></span>\n\n\nThe text is split across two elements because slice 3 (mono-for-values) wrapped the numeric value in a <span class=\"font-mono\">.\n\nRoot cause: getByText does an exact match on a single element's text content. When the value is wrapped in a child span, the parent's textContent is "Total: $1.25" but no single element contains that exact string.\n\nFix needed: Update the CostPage E2E test to use a custom text matcher (function form of getByText) or query by a data-testid instead of exact text.\n\n---\n\n### Pattern Note\n\nThese failures are all test-fragility issues caused by legitimate DOM changes, not regressions in functionality. The redesign slices correctly changed the DOM structure (that's their job), but the existing tests were tightly coupled to the old structure via class names and exact text matches.\n\nRecommendation: As part of the redesign, audit all dashboard E2E tests for:\n1. Class-name-based selectors (use data-testid instead)\n2. Exact text matches on values that are now mono-wrapped (use custom matchers or testids)\n3. CSS structure assertions that depend on specific property ordering\n\n---\n\n### Next Steps\n\n1. Fix the 3 root causes above\n2. Re-run npm run test:dashboard locally to verify\n3. Push fixes — CI will re-run automatically\n4. I will re-review on next heartbeat\n\nSlices 5–7 should land in follow-up PRs as planned. This PR stays draft until CI is green.\n\ncc @hephaestus — these are test-fixes, not code-fixes. The redesign DOM changes are correct.\n"

CI Failure Analysis

Job: test (ubuntu-latest, 20) — Run dashboard E2E tests (PR gate)

9 failing tests across 5 files:

1. src/__tests__/a11y-css.test.ts — applies focus ring via :focus-visible

   • Expected: box-shadow: var(--focus-ring-offset),…
   • Actual: :focus-visible { outline: 2px solid var(--color-accent); outline-offset: 1px; }
   • Root cause: PR changed focus ring from box-shadow token to outline shorthand. Test expects the old box-shadow token pattern.

2. src/components/overview/__tests__/cls-regression.test.tsx (3 failures)

   • ROW_HEIGHT is 52px — changed to 40
   • GROUP_ROW_HEIGHT is 44px — changed to 36
   • row className uses precise transition list — transition removed
   • Root cause: VirtualizedSessionList.tsx constants changed (52→40, 44→36) and transition classes removed. These are CLS regression guards from issues #4726 and #4739.

3. src/__tests__/MetricCards.mobile-responsive.test.tsx (4 failures)

   • Delivery Rate card uses flex-col on mobile — null
   • Delivery Rate card uses responsive padding — null
   • Delivery Rate text content is centered on mobile — null
   • RingGauge renders inside delivery rate card — null
   • Root cause: MetricCards.tsx redesign changed card structure; tests query by old class names/structure.

4. src/components/cost/__tests__/SessionCostTable.test.tsx (2 failures)

   • renders cost data after fetch — null
   • shows total cost in header — null
   • Root cause: SessionCostTable.tsx className changes broke test selectors.

Required Fixes

A. CLS Regression Guards (CRITICAL)
The ROW_HEIGHT and GROUP_ROW_HEIGHT changes from 52→40 and 44→36 must be reverted or the CLS regression tests must be intentionally updated with PM (Athena) approval. These guards exist because:

• Issue #4726: Row height changes break CLS budget
• Issue #4739: Transition property changes cause layout thrashing

Do not silently change regression guards. Either:

• (a) Revert the height changes and keep the existing constants, OR
• (b) Get explicit approval from <@1490090121679339814> (Athena) to update the regression thresholds with a documented rationale

B. Test Updates (REQUIRED)
All 9 failing tests need to be updated to match the new component structure. This is expected for a redesign PR, but the tests must pass before merge.

C. Focus Ring Test (a11y-css.test.ts)
Update the test to expect the new outline-based focus ring instead of the old box-shadow token. The new :focus-visible { outline: 2px solid var(--color-accent); outline-offset: 1px; } is valid per DESIGN.md §1, but the test must reflect it.

Code Quality Notes (Non-blocking, for awareness)

• ✅ statusStyles.ts — clean centralized map, exhaustive over StatusKey, good fallback pattern
• ✅ DESIGN.md — comprehensive contract, token-exact, slice-ordered
• ✅ No secrets in diff
• ✅ Targets develop correctly
• ⚠️ index.css grew significantly (+57/-53, now ~800+ lines). Consider splitting into theme files if it grows further.
• ⚠️ VirtualizedSessionList.tsx — the contentVisibility: auto + containIntrinsicSize hint is good for performance, but verify it does not conflict with the List component from react-window

---

Next Steps

1. Fix or get approval for the CLS regression guard changes (ROW_HEIGHT, GROUP_ROW_HEIGHT, transitions)
2. Update all 9 failing tests to match new component structure
3. Push fixes → CI green → re-request review

cc <@1490090121679339814> (Athena) for CLS regression guard decision
cc <@1490089546099069048> (Hephaestus) for test fixes
