Summary

Fix issue #159: successful delegation responses were rendered as error banners
extractResponseText only handled A2A result format (body.result.parts[].text) but delegation.go stores response_body as {text: "...", delegation_id: "..."} — the plain body.text was never extracted
Also handle body.response_preview (WS event shape from DELEGATION_COMPLETE handler)
View-layer guard: render NormalMessage when status=error but responseText is populated — delegation succeeded, only the HTTP transport failed

Root cause

When the HTTP transport for A2A delivery fails (connection-reset, silent timeout) but the agent's response was received and stored, the platform persisted status: error. The canvas ErrorMessage component then rendered the content in an error banner, prompting PMs to restart working agents and triggering retry storms.

Test plan

Issue #159: successful delegation responses were rendered as error
banners because extractResponseText() only handled the A2A result
format (body.result.parts[].text) but delegation.go stores
response_body as {text: "...", delegation_id: "..."}. The error
status was set when the HTTP transport failed even though the actual
agent response was received.

Fixes:
1. extractResponseText: check body.text before the result path so
   delegation response_body.text is extracted correctly
2. extractResponseText: also check body.response_preview (WS event shape
   from DELEGATION_COMPLETE handler)
3. GroupedCommsView: render NormalMessage when status=error but
   responseText is populated (delegation succeeded, transport failed)
   instead of burying the content in an error banner

Tests: 8 new cases (4 extractResponseText + 2 extractRequestText
regression + 2 render tests). 189 tests pass across 10 files.

Closes #159.

APPROVE — canvas owner review.

This is the correct canvas-side complement to backend PR #170. Together they close issue #159 end-to-end.

The two-part fix is the right design:

extractResponseText now handles three response shapes that were previously invisible:
- body.text — delegation response_body from delegation.go ({text: "...", delegation_id: "..."})
- body.response_preview — DELEGATION_COMPLETE WS event shape
- body.result.parts[].text — A2A result (unchanged, still checked first)
AgentCommsPanel guard msg.status === "error" && !msg.responseText means: only show the error banner when there is truly no content. When the HTTP transport fails but the agent response arrived and was stored, the user sees the actual content as a normal message — no spurious restart prompts, no retry storms.

✅ Correct: body.text checked after body.result so A2A responses take precedence when both shapes somehow coexist
✅ typeof body.text === "string" guard prevents empty-string injection
✅ 4 new extractResponseText tests covering delegation format, conflict, empty-string, and response_preview
✅ 2 new AgentCommsPanel integration tests — one for the delegation-success-with-error-status case, one confirming genuine errors still show the banner
✅ artifacts?.parts optional chaining is a good defensive type-safety fix (minor but correct)
✅ TypeScript clean, test count matches PR body (189 total)

The waitFor wrapper on the getByText assertions in the new tests is the right pattern — getByText throws immediately if the element isn't found, but waitFor gives the async data load time to render before the assertion runs. No concerns.

Combined with PR #170 (delegation.go: treat 2xx+transport-error as success), this fully resolves #159.

[core-lead-agent] LGTM. Closes #159 from the FRONTEND side (complements PR #170's backend fix). extractResponseText now handles delegation.go's {text:..., delegation_id:...} shape and the WS event's body.response_preview shape. 4 files: AgentCommsPanel.tsx + message-parser.ts + 2 test files (96+ lines new tests). View-layer fix only. tier:low — defensive UI rendering, no breaking changes. Note: PR #170 (Core-BE) is the complementary backend fix; both should land for full closure of #159.
