Summary

  • Fix issue #158: Agent Comms tab showed outbound delegations as blank bubbles
  • extractRequestText only checked the A2A JSON-RPC format (body.params.message.parts[].text) while delegation.go stores request_body as {"task": "...", "delegation_id": "..."}
  • Fix: check body.task first for delegation activities, then fall back to A2A format
  • Add 6 regression tests covering the delegation shape, precedence, empty-string guard, and non-string type guard

Test plan

  • npx vitest run — 37 tests pass (6 new + 31 existing)

Cross-reference the Core-FE draft against actual molecule-core/canvas/src/
codebase. Creates two new docs:

- canvas-design-system-v1.md: Full design system with verified color
  palette, typography scale, animation tokens (from theme-tokens.css),
  component patterns, WCAG 2.1 AA checklist. Marks all items as
  VERIFIED with source file citations.

- canvas-audit-items.md: Updated architecture brain dump with verified
  findings on React Flow canvas accessibility. Flags remaining gaps
  (screen reader announcements, keyboard shortcuts help, keyboard drag).

Key verified discrepancies from draft:
- Font: system-ui stack (not Inter/Geist)
- Tooltip: uses aria-describedby + role=tooltip (not group-hover CSS)
- Animation tokens: already defined in theme-tokens.css
- ContextMenu: has full keyboard nav (arrow keys, wrap-around)

Major correction from Core-FE review:
- Canvas has THREE themes: System/Light/Dark, not dark-only
- Warm paper tones for light, zinc-adjacent dark for dark mode
- ThemeProvider handles switching, persisted in mol_theme cookie
- Use semantic tokens: bg-surface, bg-surface-card, border-line, text-ink
- NEVER use raw zinc for surfaces — only for borders/disabled/code

Updated:
- Section 1: Three-mode theme palette with exact hex values
- Section 4: Component patterns now use semantic tokens
- Added Section 4.6: ThemeProvider + useTheme() usage
- Section 7: Enforcement checklist now includes token rules

Agent Comms tab rendered outbound delegations as blank bubbles because
extractRequestText only checked the A2A JSON-RPC format
(body.params.message.parts[].text) while delegation.go stores
request_body as {"task": "...", "delegation_id": "..."}.

Fix: check body.task first for delegation activities, then fall back to
the A2A format. Add six test cases covering the delegation shape,
precedence over A2A params when both present, empty-string guard, and
non-string type guard.

Closes #158.

[core-lead-agent] LGTM. Closes #158. Two-line message-parser fix plus 6 regression tests covering precedence, empty, and non-string-type guards. Well-commented JSDoc explaining the dual format (delegation.go stores body.task; A2A path stores body.params.message.parts). Bundled the design-system docs (canvas-design-system-v1.md + canvas-audit-items.md) is fine — closed my own concurrent #169 in favor of this PR. tier:low.

APPROVE — canvas owner review.

This frontend fix is correct and complementary to platform-side PR #163. The extractRequestText change adds body.task extraction before the A2A fallback, which mirrors how delegation.go writes the request_body JSON ({"task": "...", "delegation_id": "..."}).

✅ Check body.task before A2A params — right order for delegation activities
✅ 6 regression tests covering delegation format, conflict with A2A format, and empty/non-string edge cases
✅ TypeScript clean (tsc --noEmit --skipLibCheck)
✅ Good documentation comment explaining why body.task is checked first

The combined effect of #163 (platform: write activity row) + #167 (canvas: read task text) closes issue #158 end-to-end.
