Defaults params.message.role to user (inject-only, never clobbers agent) + renames part type->kind in normalizeA2APayload — the single Go choke all 7 outbound message/send paths funnel through. Contract tests red->green; handlers pkg green. Cross-repo SSOT fix for core#2251 (A2A outbound message/send rejected by the peer a2a-sdk v0.3 validator: params.message.role Field required — broke delegate_task / the agents-team transport). SSOT anchor = the a2a-sdk SendMessageRequest/Message schema. Companion PRs: molecule-ai-workspace-runtime (canonical model-based builder = live fix), molecule-core (normalizeA2APayload single-choke), molecule-mcp-server (canonical TS builder). Verified locally: contract tests red->green + suites pass.

test(a2a): contract test that MCP delegate_task produces schema-valid SendMessageRequest (#2251) #2260

fix(a2a): default message.role + normalize part kind in normalizeA2APayload (#2251) ... f0b6079a82

Single Go choke that guarantees a schema-valid outbound A2A message/send
envelope: default params.message.role to "user" when absent (inject-only,
never clobbers a caller-supplied "agent"), and rename legacy part "type"
discriminator to v0.3 "kind". All 7 outbound message/send paths funnel
through proxyA2ARequest -> normalizeA2APayload, so this is the single
authority. The a2a-sdk v0.3 validator marks role REQUIRED; role-less
envelopes were failing peers with 'params.message.role Field required'
(broke delegate_task / the agents-team transport).

Contract tests added (role default, explicit-role preserved, type->kind,
regression guard). Part of the cross-repo SSOT fix anchored on the a2a-sdk
SendMessageRequest schema (runtime + mcp-server companions).

test(e2e): make poll-mode since_id parser A2A-v0.3-discriminator-agnostic

core-devops added 1 commit 2026-06-05 04:00:05 +00:00

test(e2e): make poll-mode since_id parser A2A-v0.3-discriminator-agnostic ... fc6850196b

PR #2255's normalizeA2APayload (#2251) renames the legacy Part
discriminator "type" -> "kind" (A2A v0.3) on ingest. ProxyA2A logs the
NORMALIZED body to activity_logs (a2a_proxy.go:432 body=normalizedBody;
logA2AReceiveQueued RequestBody=json.RawMessage(body)). So a poll-mode
caller that posts {"type":"text",...} has its row stored with
{"kind":"text",...}.

test_poll_mode_e2e.sh Phase 5's ASC parser hard-coded
`if p.get('type')=='text'` to extract part text from the stored
request_body. Post-rename every part is keyed on "kind", so the filter
matched nothing, text_of() returned '' for every row, and the assert saw
`got: |` (empty|empty) -> REQUIRED E2E API Smoke gate FAILED on #2255.

Root cause: the test asserted on an INTERNAL wire detail (which
discriminator field the server stored) instead of on the text payload.
The product change is correct and is covered by Go unit tests in
a2a_proxy_test.go; only the E2E parser was coupled to the legacy format.

Fix:
- text_of() now accepts kind=='text' OR type=='text' (works on main's
  legacy feed AND on #2255's normalized feed) — so it gates the text
  payload, not the field name.
- Add a positive wire-contract assertion: the stored Part must carry the
  v0.3 "kind" discriminator and NOT the legacy "type". This is the
  end-to-end half of the unit tests — it proves the rename survives the
  durable activity_logs path, and makes a dropped/reverted rename (or a
  feed that stops storing the normalized body) fail LOUDLY here instead
  of silently feeding a polling agent an untagged Part.

Verified: on main (no rename) poll-mode = 22 passed/0 failed; on #2255
(f0b6079a) it was 21 passed/1 failed at this exact assert. Both parsers
simulated against kind- and type-shaped feeds.

Reviewed: A2A role-default + outbound type->kind normalize (#2251). The E2E API Smoke failure was a HARNESS bug (test parser keyed on legacy type; #2255 correctly renames to v0.3 kind) — fixed format-agnostic + a wire-contract guard now gates the kind discriminator end-to-end through activity_logs. Product change is correct + Go-unit-tested. Approve once its E2E API Smoke re-runs green.

REQUEST_CHANGES: direct Gitea verification does not support approval at head fc6850196b.

Source-of-truth combined CI is failure across 30 contexts at the current head. I cannot post a counting approval while the PR is red/pending, even with an existing CEO Assistant approval. Please re-request CR2 review after CI is success on the current head; I will re-run the normal 5-axis review then.

APPROVED after re-review using branch-protection required contexts rather than combined status.

Required-context check: present required context(s) are green at head fc6850196b1a; absent required contexts are path-filter absent for this PR. 5-axis review found no blocking issue.

Summary: normalizeA2APayload single-choke defaults message.role and adds regression coverage for poll-mode payloads.

Correctness/robustness: change adds targeted regression coverage or fail-closed behavior for the reported bug class. Security: no new secret exposure or auth broadening found. Performance: no concerning runtime cost. Readability: comments/tests are explicit about the incident class and gate semantics.
