 ### Added
 
 
+
+- **Spec clarifications: layer boundary DI exception, ULID scope, TUI/ACMS gap-fill** (#11030): Added targeted clarifications to docs/specification.md — (1) application/container.py as the sole permitted location for infrastructure concrete types in the application layer, (2) distinction between domain entity IDs (must be ULID) and ephemeral internal implementation IDs, (3) per-stage protocol contract table for 10-component ACMS pipeline with storage tier definitions, budget enforcement protocol, and AssembledContext output format, (4) TUI component public interface table for 8 components with verifiable checks. No existing content was modified or removed.
 - **Plan checkpoint management CLI commands** (#8683): Added `agents plan checkpoint-list <plan-id>` and `agents plan checkpoint-delete <checkpoint-id>` commands. Listing output now highlights checkpoint ID, type, created timestamp, reason, phase, and decision linkage with a concise field summary footer across rich/table/json/yaml formats. Deletion supports batch IDs, interactive confirmation (skip with `--yes`), and structured JSON/YAML responses for automation-friendly scripting.
 - **Invariant Remove CLI Command** (#8530): Implemented `agents invariant remove <id>` command that soft-deletes an invariant by ID. The command displays a confirmation prompt before removal (bypassable with `--yes`/`-y`), outputs the removed invariant ID on success, and shows a clear error message when the invariant ID does not exist. Supports `--format` flag for JSON and YAML output. Full BDD test coverage and Robot Framework integration tests included.
 - **TDD: MCPToolAdapter.infer_resource_slots() TypeError with null properties** (#10470):

 * HAL 9000 has contributed the plugin entry point security hardening fix (#7476): enforced entry point allowlist validation before importing plugin modules to prevent malicious plugin loading.
 * HAL 9000 has contributed the benchmark workflow separation (#9040): moved the benchmark-regression job out of the default PR workflow into a dedicated scheduled workflow, reducing median PR CI turnaround time from 99-132 minutes to under 30 minutes.
 * HAL 9000 has contributed the agent-evolution-pool-supervisor PR metadata assignment (#7888): the supervisor now automatically looks up the Type/Automation label and earliest open milestone before dispatching improvement PR creation workers, ensuring all generated improvement PRs have correct Type labels and milestone assignments.
