## Fixes Applied
### Typed Identifiers (Session 1)
Replaced raw `String` IDs with typed identifiers in internal types:
- `models/database_rows.rs` - All structs use typed IDs
- `models/agent_info.rs` - `AgentId`
- `models/context.rs` - `ContextId`, `TaskId`, `MessageId`, `SkillId`, `McpExecutionId`
- `models/external_integrations.rs` - `AgentId`, `McpServerId`
- `services/shared/config.rs` - `AgentId`
- `services/skills/skill.rs` - `SkillId`
- `api/routes/contexts/webhook/types.rs` - `ContextId`, `UserId`
- `services/a2a_server/streaming/*.rs` - `MessageId`
### Repository Pattern Enforcement (Session 1)
- Moved SQL from `artifact_publishing.rs` to `repository/execution/mod.rs`
- Added `mcp_execution_id_exists()` method to `ExecutionStepRepository`
### Dead Code Removal (Session 1)
- Removed unused `db_pool` field from `ToolResultHandler`
### Silent Error Handling Fixes (Session 2)
All `.ok()` calls now log errors before converting to Option:
- `services/registry/security.rs` - JSON parsing with logging
- `services/a2a_server/auth/validation.rs` - Permission parsing with logging
- `services/mcp/artifact_transformer/mod.rs` - Tool argument serialization
- `repository/task/constructor/batch_builders.rs` - Step status/content parsing
- `services/skills/ingestion.rs` - Directory traversal errors
- `services/a2a_server/processing/task_builder/builders.rs` - Tool response parsing
### Fire-and-Forget Pattern Fixes (Session 2)
All `let _ =` patterns replaced with explicit error handling:
- `services/a2a_server/processing/message/message_handler.rs` - Broadcast events
- `services/agent_orchestration/event_bus.rs` - Event bus publishing
- `services/a2a_server/streaming/initialization.rs` - Error events
- `services/a2a_server/streaming/agent_loader.rs` - Error events
- `services/a2a_server/streaming/event_loop.rs` - Status events, task updates
- `services/a2a_server/streaming/handlers/completion.rs` - Status events, task updates
- `services/agent_orchestration/orchestrator/mod.rs` - Startup events
### Additional `.ok()` Logging Fixes (Session 3)
Added logging before remaining `.ok()` calls:
- `services/artifact_publishing.rs:30` - ExecutionStepRepository initialization
- `services/agent_orchestration/port_manager.rs:169,243` - Process info lookup
- `services/a2a_server/streaming/initialization.rs:60` - MCP server lookup
- `services/a2a_server/processing/message/stream_processor/processing.rs:121,152` - Channel sends
- `repository/context/message/parts.rs:198` - UUID parsing
### File Size Reduction (Session 3)
Split files to meet 300-line limit:
- `repository/execution/mod.rs` - Extracted parse_step helper (303→300 lines)
- `services/a2a_server/streaming/initialization.rs` - Moved structs to types.rs (317→285 lines)

## Architectural Compliance
Cross-domain dependencies are **acceptable** per `instructions/information/boundaries.md`:
> "Domain crates using another domain's public API is acceptable when: Dependency is downward (orchestration layer using lower-level service)"
The agent crate legitimately orchestrates:
- `systemprompt-mcp` - Tool orchestration
- `systemprompt-ai` - AI model orchestration
- `systemprompt-oauth` - Authentication
- `systemprompt-users` - User lookup
- `systemprompt-files` - File handling
- `systemprompt-analytics` - Metrics

## API Protocol Types
The following files use `String` for `task_id`, `context_id` in API boundary types. These are intentionally String because:
- They're JSON-RPC protocol types matching external API spec
- Use `impl Into<String>` constructors
- Changing would break API compatibility
Files: `models/a2a/protocol/events.rs`, `models/a2a/protocol/push_notification.rs`, `models/a2a/protocol/requests.rs`
---
## Other Acceptable String ID Patterns
| `repository/task/queries.rs:145-146` | `TaskContextInfo.context_id`, `user_id` | SQLX result struct with typed accessor methods |
| `api/routes/contexts/webhook/types.rs:8` | `entity_id` | Polymorphic API field (can be task, context, etc.) |
| `services/external_integrations/webhook/service/types.rs:32,42` | `endpoint_id` | No `EndpointId` type exists in identifiers crate |
