Replace the A2aHttpTransport stub with a working HTTP(S) transport that:

- Connects to remote A2A servers via HTTPS (with configurable TLS verification)
- Sends JSON-RPC 2.0 requests over HTTP POST
- Parses JSON-RPC responses into A2aResponse objects
- Handles HTTP errors (4xx/5xx) with structured error mapping
- Supports JWT Bearer token authentication
- Validates connection state before send operations

Added comprehensive test coverage:
- Behave BDD scenarios for validation and lifecycle testing
- Pytest unit tests with mocked HTTP responses covering success,
  errors, network failures, auth tokens, and roundtrip serialization

PR Review — feat(a2a): implement server-mode HTTP transport for A2A agent communication

Overall verdict: REQUEST_CHANGES — Multiple blocking issues must be resolved before this PR can be approved.

CI Status (BLOCKING)

The following required CI gates are failing:

Job Status
lint FAILING
typecheck FAILING
security FAILING
unit_tests FAILING
integration_tests FAILING
benchmark-regression FAILING
status-check FAILING

Per company policy (CONTRIBUTING.md), all CI gates must pass before a PR can be approved. The specific failures identified during code review are documented below.

1. Correctness

The core implementation logic is broadly correct: connect(), disconnect(), is_connected(), and send() implement the required interface. JSON-RPC 2.0 request/response framing works correctly.

BUG (blocking): There is an arithmetic inconsistency in the HTTP 4xx error code mapping. The formula error_code = -32000 + (status_code - 400) produces -31996 for HTTP 404. The test in both test files asserts response.error.code == -31997. One of these is wrong — align the implementation and the test. Note also that the comment in the test says -32000 + (404-400) = -31996 yet asserts -31997, so the code is internally self-contradicting.

2. Specification Alignment

PASS — The implementation replaces the stub with a working transport as described in issue #10921. The interface (connect, send, disconnect, is_connected) matches the specification requirement.

3. Test Quality (BLOCKING)

Multiple critical test placement and framework violations:

BLOCKING: tests/unit/a2a_test_http_transport.py and tests/unit/__init__.py are placed in tests/unit/, which is NOT a valid directory in this project. The project layout per CONTRIBUTING.md mandates:

  • Unit tests (BDD) go in features/ using Behave exclusively
  • tests/ does not exist in the prescribed directory layout

Remove these files. All test coverage must be expressed as Behave scenarios in features/ with step definitions in features/steps/.

BLOCKING: features/steps/test_a2a_http_transport_pytest.py is a pytest file placed inside features/steps/. This directory is exclusively for Behave step definition modules (*_steps.py). A pytest file here will confuse the Behave test runner and is not executed by nox -s unit_tests. Remove this file and convert the coverage to Behave scenarios.

BLOCKING: features/steps/a2a_facade_steps.py contains duplicate Python function names for step_transport_connect. Python silently overwrites earlier definitions, causing Behave step resolution to break. See inline comment for details.

The features/a2a_http_transport.feature scenarios are reasonable and should be kept. However, the mock setup inline in a2a_facade_steps.py uses unittest.mock.patch inline — mock objects should be placed in features/mocks/ per CONTRIBUTING.md.

4. Type Safety (BLOCKING)

The typecheck CI job is failing. Specific concerns:

  • features/steps/a2a_facade_steps.py calls context.transport.connect(url, tls_verify=False) but connect() does not accept a tls_verify kwarg. This is a type error AND a runtime error. The # type: ignore[arg-type] comment is also prohibited (zero tolerance).
  • Both pytest test files contain # type: ignore[arg-type] suppressions. Per CONTRIBUTING.md, # type: ignore is never permitted. Every suppression must be removed and the underlying type issue resolved.

5. Readability

PASS — Code is clear and well-structured. Variable names are descriptive.

6. Performance

PASS — No unnecessary operations. Suggestion (non-blocking): Consider making the timeout=30 configurable via __init__ rather than hardcoded.

7. Security (BLOCKING)

The security CI job is failing. Specific concern:

_get_ssl_context() when tls_verify=False uses bare SSLContext() with context.verify_mode = 0. The integer literal 0 is a magic number; it should be ssl.CERT_NONE. Bandit will flag this as a security issue. Fix:

import ssl
context = ssl.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
context.check_hostname = False
context.verify_mode = ssl.CERT_NONE

8. Code Style (BLOCKING)

The lint CI job is failing. Specific concerns:

BLOCKING: map_domain_error is imported in transport.py but never called. Ruff F401 (unused import). Remove it or use it — the issue acceptance criterion requires domain errors to be mapped via map_domain_error.

BLOCKING: BytesIO is imported in both test files but never used. Ruff F401.

9. Documentation

PARTIAL PASS — The class docstring is present. Suggestion (non-blocking): Add docstrings to all public methods (connect, send, disconnect, is_connected) explaining parameters, return values, and raised exceptions.

10. Commit and PR Quality (BLOCKING)

BLOCKING — Empty PR body: The PR description is completely empty. It must include a summary of changes and a closing keyword: Closes #10921. Without this, the issue will not auto-close on merge and the PR violates requirement 1 of the PR checklist.

BLOCKING — Commit footer missing ISSUES CLOSED: The commit (SHA 2d5a4ce) has no ISSUES CLOSED: #10921 line in the footer. Every commit must reference its issue.

BLOCKING — No milestone: The PR has no milestone assigned. This is mandatory per CONTRIBUTING.md once the issue is in an active state.

BLOCKING — No Type/ label: The PR has no Type/Feature label. Exactly one Type/ label is required.

BLOCKING — CHANGELOG not updated: CHANGELOG.md on this branch is identical to master. Add an entry under [Unreleased] describing the A2A HTTP transport implementation.

BLOCKING — Branch name format incorrect: The branch is named feat/issue-10921-a2a-http-transport. The required format is feature/mN-<descriptive-name> (note: feature/, not feat/; the milestone number N must appear). For example: feature/m8-a2a-http-transport.

Summary of All Blocking Issues

  1. CI: lint, typecheck, security, unit_tests, integration_tests, benchmark-regression all failing
  2. Tests: tests/unit/ is not a valid project directory — remove pytest files
  3. Tests: features/steps/test_a2a_http_transport_pytest.py is a pytest file in a Behave-only directory
  4. Tests: Duplicate step_transport_connect function in a2a_facade_steps.py
  5. Type Safety: # type: ignore suppressions are prohibited
  6. Type Safety: connect() called with undeclared tls_verify=False kwarg in step file
  7. Security: bare SSLContext() with magic number 0 — use ssl.CERT_NONE
  8. Code Style: map_domain_error imported but unused in transport.py
  9. Code Style: BytesIO imported but unused in test files
  10. Correctness: Off-by-one in 4xx error code mapping — test comment and assertion disagree
  11. PR Quality: Empty PR body — add description and Closes #10921
  12. PR Quality: Commit footer missing ISSUES CLOSED: #10921
  13. PR Quality: No milestone assigned
  14. PR Quality: No Type/Feature label
  15. PR Quality: CHANGELOG.md not updated
  16. PR Quality: Branch name uses feat/ prefix instead of feature/mN- format

BLOCKING — Duplicate Python function name step_transport_connect

This file contains multiple @when(...) decorated functions all named step_transport_connect:

  1. The original @when(r'I try to connect via the transport to "(?P<url>[^"]+)"') (existing stub step)
  2. @when(r"I connect the transport to (.+)") (new step added in this PR)
  3. @when(r"the transport is connected to (.+)") (new step added in this PR)

Python silently overwrites earlier function definitions with the same name. This means Behave will only ever dispatch to the last-defined step_transport_connect, causing the earlier steps to silently do the wrong thing or raise unexpected errors.

Rename each function to a unique, descriptive name, e.g.:

  • step_try_connect_via_transport_to_url (for the I try to connect variant)
  • step_connect_transport_to_url (for I connect the transport to)
  • step_transport_is_connected_to_url (for the transport is connected to)

BLOCKING — # type: ignore[arg-type] is prohibited + runtime error

context.transport.connect(url.strip("'\""), tls_verify=False) passes tls_verify=False as a keyword argument to connect(), but connect() does not accept that parameter. This will raise TypeError at runtime AND Pyright will flag it as a type error.

The # type: ignore[arg-type] comment is absolutely prohibited by CONTRIBUTING.md (zero tolerance, no exceptions).

The tls_verify setting is configured at construction time via __init__. To test with TLS disabled, construct the transport with that setting:

@given(r"a new A2aHttpTransport with TLS disabled")
def step_transport_tls_off(context: Context) -> None:
    context.transport = A2aHttpTransport(tls_verify=False)

Then connect normally. Remove the tls_verify=False kwarg from the connect() call and delete the # type: ignore comment.

BLOCKING — Pytest file must not exist in features/steps/

This is a pytest test module placed in features/steps/, which is exclusively for Behave step definition files. The project uses Behave for all unit tests (nox -s unit_tests runs Behave, not pytest). This file is not executed by the test runner and will confuse Behave's step discovery.

Additionally BytesIO is imported but never used — ruff will flag this as F401.

Action required:

  1. Delete this file entirely.
  2. Ensure the test scenarios it covers are represented as Behave scenarios in features/a2a_http_transport.feature with step definitions in features/steps/a2a_http_transport_steps.py.
  3. Place any mock helpers in features/mocks/.

BLOCKING — Unused import causes lint failure (Ruff F401)

map_domain_error is imported at line 5 but is never called anywhere in this file. Ruff will flag this as F401, causing the lint CI job to fail.

The issue acceptance criterion states: "Domain errors are mapped via map_domain_error". Either remove the unused import, or fulfil the acceptance criterion by using it in the send() method to translate caught domain exceptions:

except CleverAgentsError as exc:
    code, message = map_domain_error(exc)
    detail = A2aErrorDetail(code=code, message=message)
    return A2aResponse(id=request.id, error=detail)

BLOCKING — Security: bare SSLContext() with magic-number verify_mode = 0

Bandit will flag two issues here:

  • B501: SSLContext() instantiated without specifying a protocol
  • The integer literal 0 is a magic number for ssl.CERT_NONE

Fix by using named constants and PROTOCOL_TLS_CLIENT:

import ssl
context = ssl.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
context.check_hostname = False
context.verify_mode = ssl.CERT_NONE
return context

This is the correct pattern for disabling TLS verification while still using a properly constructed SSL context.

BLOCKING — tests/unit/ is not a valid project directory

This project does not use tests/ as a test directory. The CONTRIBUTING.md directory layout prescribes only features/ (Behave BDD unit tests), features/mocks/ (test doubles), and robot/ (Robot Framework integration tests). There is no tests/ directory in the project structure.

Additionally:

  • BytesIO is imported but never used (Ruff F401)
  • The test uses pytest, which is not the project's unit test framework

Action required:

  1. Delete tests/unit/a2a_test_http_transport.py and tests/unit/__init__.py.
  2. Convert the test coverage expressed here into Behave scenarios in features/a2a_http_transport.feature with step definitions in features/steps/a2a_http_transport_steps.py.

The scenarios in the existing features/a2a_http_transport.feature are a good start — they need step implementations that cover the same cases (SSL context, headers, roundtrip, network errors, etc.).

Labels
Clear labels   
auto/needs-reevaluation
Controller deferred this PR; awaiting Phase 6+ scope-evaluator or operator re-enablement.

  
controller-managed
Auto-agents controller manages this PR/issue (see tools/controller/deploy/RUNBOOK.md). Remove this label to abandon controller management.

  
auto/blocked-by-deps
PR blocked by an open issue dependency. Operator must close the dep (or remove the dependency link) before the merge driver can act. Auto-cleared by merge_drive when no open deps remain.

  
auto/ci-timeout
Most recent merge cycle hit CI timeout. Driver excludes this PR while last merge_cycle row is < 30 min old; label persists thereafter as visible history.

  
auto/claimed-implementer
Currently being processed by an implementer worker.

  
auto/claimed-merge
Currently being processed by the merge driver.

  
auto/claimed-reviewer
Currently being processed by a reviewer worker.

  
auto/driver-down
Merge driver heartbeat stale; pipeline halted. Closed automatically on next clean tick.

  
auto/invariant-violation
Detected master commit violating the strict merge invariant. Tracked as an issue (not a PR label); kept here for label completeness.

  
auto/last-attempt-tier-0
In-cycle escalation: most recent attempt ran at the Tier 0 slot (`tier-0`). Slot's model defined in .opencode/models/tiers.yaml.

  
auto/last-attempt-tier-1
In-cycle escalation: most recent attempt ran at the Tier 1 slot (`tier-1`). Slot's model defined in .opencode/models/tiers.yaml.

  
auto/last-attempt-tier-2
In-cycle escalation: most recent attempt ran at the Tier 2 slot (`tier-2`). Slot's model defined in .opencode/models/tiers.yaml. Gated behind IMPLEMENTER_ESCALATION_TIER2_ENABLED.

  
auto/last-attempt-tier-min
In-cycle escalation: most recent attempt ran at the Tier -1 slot (`tier-min`). Slot's model defined in .opencode/models/tiers.yaml. Suffix is ``-min`` (not ``--1``) so the Forgejo UI reads naturally.

  
Automation Tracking
Tracking issues used by the AI Automation system for agents to communicate and report.

  
auto/needs-conflict-resolution
Rebase conflict needs LLM conflict-resolver.

  
auto/needs-implementer
Failing CI needs implementer attention.

  
auto/postmortem
Documenting a driver incident or rollback.

  
auto/ready-to-merge
Reviewer has APPROVED this PR and no later REQUEST_CHANGES is outstanding. The merge driver requires this label to even consider a PR for merging. Set by the reviewer worker on APPROVE; cleared on REQUEST_CHANGES.

  
auto/restart-throttled
Train repeatedly lost master-tempo races. Driver excludes via merge_cycle until cooldown elapses; label persists as visible history.

  
auto/revert
Revert PR backing out an invariant violation. Fast-tracked through the merge driver.

  
auto/sentinel
Sentinel PR duplicated from upstream into a personal fork by tools/duplicate_prs_to_fork.py for pipeline testing. Lives only in the fork; the canonical pipeline never sees it.

  
auto/stale-inactivity
No implementer activity for N days. Flagged for human review. Auto-cleared on next push to head branch.

  
auto/unstable
Repeatedly fails on current master (>= 3 ci-fail-on-rebased-sha releases in 12 h). Excluded from driver until human triage.

  
Blocked
A ticket in a blocked state and unable to complete until some other task is completed first.
