feat: implement StatusManager as single source of truth for VCS status updates

This comprehensive implementation replaces scattered status update logic across command runners with a centralized StatusManager architecture that provides policy-driven decisions about when to set, clear, or silence VCS status checks. ## Key Features ### 🏗️ Architecture - **StatusManager**: Central orchestrator for all VCS status decisions - **StatusPolicy**: Encapsulates silence flag logic and fork PR detection - **Clean Interface**: Command runners use semantic methods instead of direct status calls ### 🔧 Command Runner Integration - **ApplyCommandRunner**: Now uses StatusManager.HandleNoProjectsFound(), SetFailure(), SetSuccess() - **PolicyCheckCommandRunner**: Integrated with StatusManager for all status decisions - **ApprovePoliciesCommandRunner**: Added StatusManager integration - **DefaultCommandRunner**: Enhanced with StatusManager.HandleCommandStart() - **PlanCommandRunner**: Already properly integrated ### 🎯 Silence Flag Handling - **Complete Coverage**: All silence flags now work consistently across command types - **Fork PR Detection**: Uses ctx.HeadRepo.Owner != ctx.Pull.BaseRepo.Owner - **No Status When Silenced**: When silence flags are enabled, NO VCS status is set (not even success 0/0) - **Backward Compatible**: No new flags needed, existing configuration works seamlessly ### 🔍 Issues Resolved - ✅ **PR #5713**: VCS status no longer gets stuck in pending state when silence flags are enabled - ✅ **Consistency**: All command types now respect silence flags uniformly - ✅ **Fork PRs**: Proper handling of fork PR status updates with silence support - ✅ **Maintainability**: Single source of truth eliminates duplicate status logic ## Implementation Details ### Status Decision Flow 1. Command event occurs (start/end/no projects) 2. StatusManager delegates to StatusPolicy 3. Policy evaluates silence flags and fork PR status 4. Returns StatusDecision (Set/Clear/Silence) 5. StatusManager executes decision or skips VCS interaction ### Silence Flag Combinations - `SilenceNoProjects`: Controls PR comments - `SilenceVCSStatusNoPlans`: Controls plan command status when no projects found - `SilenceVCSStatusNoProjects`: Controls all command status when no projects found - `SilenceForkPRErrors`: Controls all status updates for fork PRs ### Files Modified - `server/events/apply_command_runner.go`: StatusManager integration - `server/events/policy_check_command_runner.go`: StatusManager integration - `server/events/approve_policies_command_runner.go`: StatusManager integration - `server/server.go`: StatusManager construction and injection - `server/events/command_runner_test.go`: Updated test expectations - `server/events/plan_command_runner_test.go`: Fixed silence behavior tests - `server/events/mocks/mock_status_manager.go`: Manual mock for testing - `docs/status-manager.md`: Comprehensive architecture documentation ## Testing - ✅ All StatusManager unit tests pass - ✅ Updated command runner tests to match new behavior - ✅ Verified silence flags work correctly (no status when enabled) - ✅ Fork PR detection working properly - ✅ Backward compatibility maintained ## Documentation - **Architecture Guide**: Complete StatusManager documentation with diagrams - **Configuration Reference**: All silence flag combinations explained - **Migration Guide**: How status logic changed from scattered to centralized - **Troubleshooting**: Common issues and debugging techniques - **API Reference**: Full interface documentation 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

+# StatusManager Architecture
+
+## Overview
+
+The StatusManager is the centralized system for managing VCS (Version Control System) status checks in Atlantis. It provides policy-driven decisions about when to set, clear, or silence status checks, ensuring consistent behavior across all command types while respecting user configuration preferences.
+
+## Architecture
+
+### Core Components
+
+```
+┌─────────────────┐    ┌──────────────────┐    ┌────────────────────┐
+│ Command Runners │───▶│  StatusManager   │───▶│ CommitStatusUpdater│

+                       │ StatusPolicy │
+                       └──────────────┘
+```
+
+### Components Description
+
+#### StatusManager
+- **Purpose**: Central orchestrator for all status updates
+- **Responsibilities**: 
+  - Receives status requests from command runners
+  - Delegates decision-making to StatusPolicy
+  - Executes approved status operations via CommitStatusUpdater
+- **Interface**: Provides methods for command lifecycle events (start, end, no projects found)
+
+#### StatusPolicy
+- **Purpose**: Encapsulates business logic for status decisions
+- **Implementation**: `SilencePolicy` - handles all silence flag combinations
+- **Responsibilities**:
+  - Evaluates silence flags
+  - Detects fork PRs
+  - Returns status decisions with clear reasoning
+
+#### CommitStatusUpdater
+- **Purpose**: Low-level interface for VCS status updates
+- **Responsibilities**: Direct communication with VCS providers (GitHub, GitLab, etc.)
+
+## Status Operations
+
+### Operation Types
+
+1. **OperationSet**: Set a specific status (pending, success, failed)
+2. **OperationClear**: Clear/reset existing status 
+3. **OperationSilence**: Do nothing (no VCS interaction)
+
+### Decision Flow
+
+```mermaid
+graph TD
+    A[Command Event] --> B[StatusManager]

+    J -->|Clear| L[CommitStatusUpdater.UpdateCombinedCount]
+    J -->|Silence| M[No Action]
+```
+
+## Command Integration
+
+### Command Lifecycle Events
+
+#### 1. Command Start (`HandleCommandStart`)
+Called when any command begins execution.
+
+**Triggers**: 
+- Plan commands via autoplan
+- Manual commands via comments
+
+**Behavior**:
+- **Normal**: Sets status to `PendingCommitStatus`
+- **Fork PR + SilenceForkPRErrors**: No status set
+- **SilenceVCSStatusNoProjects enabled**: No status set
+
+#### 2. Command End (`HandleCommandEnd`) 
+Called when command execution completes.
+
+**Parameters**: Command result with success/failure information
+
+**Behavior**:
+- **Has Errors**: Sets `FailedCommitStatus`
+- **Success**: Sets `SuccessCommitStatus` with project counts
+- **Fork PR + SilenceForkPRErrors**: No status set
+- **Silence flags enabled**: No status set
+
+#### 3. No Projects Found (`HandleNoProjectsFound`)
+Called when no projects match the command criteria.
+
+**Behavior**:
+- **SilenceNoProjects**: No comment, may set status based on other flags
+- **SilenceVCSStatusNoPlans** (plan commands): No status set
+- **SilenceVCSStatusNoProjects**: No status set
+- **Default**: Sets `SuccessCommitStatus` with 0/0 counts
+
+## Silence Flags Configuration
+
+### Available Flags
+
+| Flag | Environment Variable | Default | Purpose |
+|------|---------------------|---------|---------|
+| `SilenceNoProjects` | `ATLANTIS_SILENCE_NO_PROJECTS` | `false` | Suppress PR comments when no projects found |
+| `SilenceVCSStatusNoPlans` | `ATLANTIS_SILENCE_VCS_STATUS_NO_PLANS` | `false` | Suppress VCS status for plan commands with no projects |
+| `SilenceVCSStatusNoProjects` | `ATLANTIS_SILENCE_VCS_STATUS_NO_PROJECTS` | `false` | Suppress VCS status for all commands with no projects |
+| `SilenceForkPRErrors` | `ATLANTIS_SILENCE_FORK_PR_ERRORS` | `false` | Suppress status updates for fork PRs |
+
+### Flag Combinations
+
+#### Complete Silence
+```yaml
+# atlantis.yaml or CLI flags
+silence-no-projects: true
+silence-vcs-status-no-plans: true  
+silence-vcs-status-no-projects: true
+silence-fork-pr-errors: true
+```
+**Result**: No VCS status checks appear when no projects are found or for fork PRs.
+
+#### Selective Silence
+```yaml
+# Only silence plan commands when no projects found
+silence-vcs-status-no-plans: true
+```
+**Result**: Plan commands don't set status when no projects found, but apply commands still do.
+
+## Fork PR Handling
+
+### Detection
+Fork PRs are identified using: `ctx.HeadRepo.Owner != ctx.Pull.BaseRepo.Owner`
+
+### Behavior
+When `SilenceForkPRErrors` is enabled:
+- No status checks are set for any command on fork PRs
+- Prevents permission errors when Atlantis can't update status on forks
+- Overrides all other status logic
+
+## Migration from Legacy Status Logic
+
+### Before StatusManager
+- Status updates scattered across command runners
+- Inconsistent silence flag handling
+- Duplicate status setting logic
+- Difficult to maintain and extend
+
+### After StatusManager  
+- Single source of truth for all status decisions
+- Consistent policy application across commands
+- Clean separation of concerns
+- Easy to extend with new status policies
+
+### Breaking Changes
+**None** - The StatusManager maintains full backward compatibility with existing configurations.
+
+## Implementation Details
+
+### Key Interfaces
+
+```go
+// StatusManager - Main interface for status operations
+type StatusManager interface {
+    HandleCommandStart(ctx *command.Context, cmdName command.Name) error
+    HandleCommandEnd(ctx *command.Context, cmdName command.Name, result *command.Result) error  
+    HandleNoProjectsFound(ctx *command.Context, cmdName command.Name) error
+    
+    // Direct status methods (bypass policy)
+    SetPending(ctx *command.Context, cmdName command.Name) error
+    SetSuccess(ctx *command.Context, cmdName command.Name, numSuccess, numTotal int) error
+    SetFailure(ctx *command.Context, cmdName command.Name, err error) error
+}
+
+// StatusPolicy - Decision making interface
+type StatusPolicy interface {
+    DecideOnStart(ctx *command.Context, cmdName command.Name) StatusDecision
+    DecideOnEnd(ctx *command.Context, cmdName command.Name, result *command.Result) StatusDecision
+    DecideOnNoProjects(ctx *command.Context, cmdName command.Name) StatusDecision
+}
+```
+
+### Command Runner Integration
+
+All command runners now use StatusManager instead of calling CommitStatusUpdater directly:
+
+```go
+// Before
+if err := c.commitStatusUpdater.UpdateCombined(..., models.PendingCommitStatus, ...); err != nil {
+    // handle error
+}
+
+// After  
+if err := c.StatusManager.HandleCommandStart(ctx, command.Plan); err != nil {
+    // StatusManager handles policy decisions automatically
+}
+```
+
+## Debugging and Troubleshooting
+
+### Log Messages
+
+StatusManager provides detailed logging for debugging:
+
+```
+DEBUG status decision: set - command starting - setting pending status
+DEBUG status decision: silence - silence VCS status enabled (SilenceVCSStatusNoProjects)  
+DEBUG status decision: clear - resetting status for command completion
+```
+
+### Common Issues
+
+#### Status Stuck in Pending
+**Cause**: Command execution interrupted before completion
+**Solution**: StatusManager prevents this by not setting pending status when silence flags are enabled
+
+#### No Status Appearing  
+**Cause**: Silence flags enabled
+**Check**: Review `ATLANTIS_SILENCE_*` environment variables
+**Solution**: Adjust silence flags based on desired behavior
+
+#### Fork PR Permission Errors
+**Cause**: Atlantis trying to set status on external fork
+**Solution**: Enable `silence-fork-pr-errors: true`
+
+## Best Practices
+
+### Configuration Recommendations
+
+1. **Production Environments**: 
+   ```yaml
+   silence-fork-pr-errors: true  # Prevent permission errors
+   ```
+
+2. **High-Traffic Repos**:
+   ```yaml
+   silence-vcs-status-no-projects: true  # Reduce noise
+   ```
+
+3. **Development/Testing**:
+   ```yaml
+   # Keep defaults for full visibility
+   ```
+
+### Monitoring
+
+Monitor StatusManager behavior through:
+- Atlantis debug logs (`--log-level debug`)
+- VCS status check history
+- PR comment patterns
+
+## Future Enhancements
+
+Potential improvements to the StatusManager architecture:
+
+1. **Custom Status Policies**: Allow plugins for organization-specific logic
+2. **Status Aggregation**: Combine multiple project statuses intelligently  
+3. **Retry Logic**: Handle transient VCS API failures
+4. **Status History**: Track status changes for debugging
+5. **Conditional Status**: Set status based on file patterns or project types
