freemo added this to the v3.6.0 milestone 2026-03-10 09:10:38 +00:00 
Implement ServerHttpClient with httpx for server communication including:
- Health check endpoint (GET /health)
- Version negotiation (GET /version, POST /version/negotiate)
- Pagination helpers for list endpoints
- Per-request timeout and retry policy with exponential backoff
- Request/response logging with auth header redaction
- TLS verification toggle with warning when disabled
- Server error responses mapped to domain errors (AcpNotAvailableError, etc.)
- Client-specific exceptions (ServerConnectionError, ServerTimeoutError, ServerVersionMismatchError)
- Settings fields: server_base_url, server_api_token, server_tls_verify, server_request_timeout
- Factory function create_client_from_settings wired to Settings
- httpx added to pyproject.toml dependencies

ISSUES CLOSED: #335
Implement PlanSyncClient for synchronizing local resources with a remote
CleverAgents server and submitting plans for remote execution:
- Sync actions, skills, tools, projects with configurable scope flags
- Conflict resolution policies (local_wins / server_wins)
- Remote plan execution, apply, and status query endpoints
- Server-side ID persistence in local item metadata
- Sync summary output (created/updated/skipped/errors)
- Dry-run mode that skips server mutations
- SyncScope, SyncSummary, ExecutionResult data models

ISSUES CLOSED: #336
Implement WebSocketClient for receiving real-time plan update events
from a CleverAgents server via WebSocket connection:
- Plan update subscription with reconnect/exponential backoff
- Event schema for plan status, progress, and log stream updates
- Heartbeat/ping handling that resets reconnect counter
- Resume from last event ID on reconnect
- Event version negotiation
- Event de-duplication by event_id via LRU-bounded EventDeduplicator
- Ordered delivery guarantees with thread-safe callback dispatch
- Configurable reconnect backoff parameters (base, max, max_reconnects)
- ConnectionState model tracking lifecycle state
- websockets library added to pyproject.toml dependencies

Implement RemoteProjectClient for accessing and executing projects
hosted on a remote CleverAgents server:
- Remote resource selection and server execution request wiring
- Project-name resolution for remote namespaces and server aliases
- Resolve project with fallback from custom to default namespace
- Remote project caching with configurable TTL (default 5 min)
- Explicit ResourceNotFoundError when remote project not found
- Cache invalidation per-namespace or global
- RemoteProject dataclass with project_id, name, namespace, alias, description

PM Decision — Closing PR (Day 31)

This PR is being closed due to a fundamental specification change that renders the implementation obsolete.

What Changed

As of today (2026-03-11), the specification was updated to adopt the A2A (Agent-to-Agent) Protocol standard (see ADR-047). Key changes:

  • No REST API: The old HTTP/REST client design (http_client.py, sync_client.py, ws_client.py) is replaced by a single JSON-RPC 2.0 endpoint
  • A2A over stdio for local mode (agent as subprocess)
  • A2A over HTTP for server mode (single JSON-RPC endpoint, not REST)
  • SSE streaming via TaskStatusUpdateEvent / TaskArtifactUpdateEvent (not WebSocket)
  • LangGraph Platform with RemoteGraph for server-side execution

Impact

This PR creates:

  • src/cleveragents/client/http_client.py — obsolete (no REST API)
  • src/cleveragents/client/sync_client.py — obsolete (A2A SDK replaces)
  • src/cleveragents/client/ws_client.py — obsolete (SSE, not WebSocket)
  • src/cleveragents/client/remote_project.py — needs redesign for A2A task model

Replacement

New issues will be created in v3.8.0 (M9 — Server) for:

  1. A2A JSON-RPC 2.0 wire format and method routing
  2. A2A stdio transport (local mode)
  3. A2A HTTP transport (server mode)
  4. LangGraph Platform RemoteGraph integration

The feature/m7-post-server branch can be archived. @freemo — the architectural patterns here (DI wiring, error handling) are still valuable as reference for the A2A implementation.

This closure is due to a change in specification, not a quality issue with the code.

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.
