From bae2b2f377e0f671c9c8a23dbea46f338900d455 Mon Sep 17 00:00:00 2001 From: HAL9000 Date: Fri, 8 May 2026 09:12:53 +0000 Subject: [PATCH 1/4] feat(plans): implement checkpoint creation for plan state snapshots Checkpoint creation functionality for capturing plan state at specific points during execution. Checkpoints are created manually via CheckpointService.create_checkpoint() or automatically at configurable intervals (on tool write, after tool execution, on subplan spawn, on error). Each checkpoint stores a sandbox reference (git commit hash), metadata (reason, source tool, phase), and optional decision/resource associations. Key features: - Manual checkpoint creation via service API and CLI - Automatic checkpoints triggered at configurable intervals - Database persistence with retention policy enforcement (default max 50) - Domain event emission on checkpoint creation for observability - Configurable retention policy injection into CheckpointService - Comprehensive BDD test coverage across lifecycle, persistence, and integration scenarios ISSUES CLOSED: #8555 --- CHANGELOG.md | 1 + CONTRIBUTORS.md | 3 +- features/checkpoint_creation.feature | 134 +++++ .../checkpoint_creation_lifecycle_steps.py | 223 ++++++++ features/steps/checkpoint_creation_steps.py | 495 ++++++++++++++++++ .../services/checkpoint_service.py | 11 +- 6 files changed, 864 insertions(+), 3 deletions(-) create mode 100644 features/checkpoint_creation.feature create mode 100644 features/steps/checkpoint_creation_lifecycle_steps.py create mode 100644 features/steps/checkpoint_creation_steps.py diff --git a/CHANGELOG.md b/CHANGELOG.md index 7c9d662fd..2fb477f5b 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -13,6 +13,7 @@ The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/). traceback in the structlog warning entry.

(#988) +- **Checkpoint Creation for Plan State Snapshots (#8555)**: Implemented checkpoint creation functionality for capturing plan state at specific points during execution. Checkpoints are created manually via `CheckpointService.create_checkpoint()` or automatically at configurable intervals (on tool write, after tool execution, on subplan spawn, on error). Each checkpoint stores a sandbox reference (git commit hash), metadata (reason, source tool, phase), and optional decision/resource associations. Checkpoints are persisted to the database with automatic retention policy enforcement (default: max 50 checkpoints per plan, with first and most recent always preserved). Checkpoint creation emits `CHECKPOINT_CREATED` domain events for observability. ### Fixed - **Actor CLI NAME argument made optional, derived from YAML config** (#4186): The `agents actor add` positional ``NAME`` argument is now optional (defaults to diff --git a/CONTRIBUTORS.md b/CONTRIBUTORS.md index 51815111f..2d4ea6a1f 100644 --- a/CONTRIBUTORS.md +++ b/CONTRIBUTORS.md @@ -33,4 +33,5 @@ Below are some of the specific details of various contributions. * HAL 9000 has contributed the LLMTraceRepository data-integrity fix (PR #8185 / issue #7505): replaced the unconditional `session.commit()` in `LLMTraceRepository.save()` with a dual-path implementation that respects the UnitOfWork pattern — flushing only when an external session is provided, and flushing + committing + closing when operating standalone. This eliminates premature transaction commits, loss of rollback capability, and a docstring/implementation mismatch. * HAL 9000 has contributed the ACMS Index Data Model and File Traversal Engine (PR #9664 / issue #9579): foundational data structures for indexed context entries with hot/warm/cold/archive storage tier classification, tag system, and a timeout-safe chunked file traversal engine for large projects with 10,000+ files. -* HAL 9000 has contributed the error-suppression removal fix (PR #9247 / issue #9060): removed both `try...except Exception:` blocks in `register_registry_agents()` that silently suppressed errors from `actor_registry.list_actors()` and the route bridge refresh, enabling exceptions to propagate per CONTRIBUTING.md fail-fast policy.

This eliminates premature transaction commits, loss of rollback capability, and a docstring/implementation mismatch. * HAL 9000 has contributed the ACMS Index Data Model and File Traversal Engine (PR #9664 / issue #9579): foundational data structures for indexed context entries with hot/warm/cold/archive storage tier classification, tag system, and a timeout-safe chunked file traversal engine for large projects with 10,000+ files. - * HAL 9000 has contributed the error-suppression removal fix (PR #9247 / issue #9060): removed both `try...except Exception:` blocks in `register_registry_agents()` that silently suppressed errors from `actor_registry.list_actors()` and the route bridge refresh, enabling exceptions to propagate per CONTRIBUTING.md fail-fast policy. Added three Behave scenarios verifying RuntimeError, AttributeError, and TypeError propagation. +* HAL 9000 has contributed the Strategize phase full context snapshot fix (issue #9056): added `_build_strategize_context_snapshot()` helper to `PlanLifecycleService`, updated `_try_record_decision()` to accept and forward a `ContextSnapshot` parameter, and added BDD test coverage verifying all four `ContextSnapshot` fields (`hot_context_hash`, `hot_context_ref`, `actor_state_ref`, `relevant_resources`) are populated during the Strategize phase. +* HAL 9000 has contributed the ACMS context path matching fix (PR #10975 / issue #10972): corrects `_path_matches()` and `_matches_pattern()` to properly match absolute fragment paths against relative glob patterns by auto-prefixing with `**/` before calling `PurePath.full_match()`, preventing silent inefficacy of include/exclude filters for absolute paths in fragment metadata. * HAL 9000 has contributed the checkpoint creation feature for plan state snapshots (issue #8555): implemented manual and automatic checkpoint creation with database persistence, retention policy enforcement, and domain event emission. -- 2.52.0 From f4d31e8f313e14a0952bf04b14fb93a658a32631 Mon Sep 17 00:00:00 2001 From: CleverThis Date: Sat, 9 May 2026 14:50:00 +0000 Subject: [PATCH 3/4] fix(plans): fix quoted-parameter bugs in Behave step patterns Resolved two remaining instances of the quoted-parameter bug in checkpoint_creation_steps.py causing unit_tests CI failures. Bug 1: file content parameter lacked surrounding quotes (line 93). Bug 2: non-existent plan_id parameter lacked surrounding quotes (line 279). ISSUES CLOSED: #8555 Both patterns passed double-quoted strings from Gherkin feature files. Without surrounding quotes in step decorator patterns, Behave captures the quote characters as part of the parameter value, causing mismatched step resolution and CI test failures. --- features/steps/checkpoint_creation_steps.py | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/features/steps/checkpoint_creation_steps.py b/features/steps/checkpoint_creation_steps.py index c100375ca..e1fdbdcc6 100644 --- a/features/steps/checkpoint_creation_steps.py +++ b/features/steps/checkpoint_creation_steps.py @@ -90,7 +90,7 @@ def step_plan_in_strategize_without_sandbox(context: object) -> None: context.error = None -@given("a file exists in the sandbox with content {content}") +@given('a file exists in the sandbox with content "{content}"') def step_file_exists_in_sandbox(context: object, content: str) -> None: """Create a file in the sandbox with specific content.""" test_file = Path(context.sandbox_path) / "test_file.txt" @@ -276,7 +276,7 @@ def step_list_checkpoints(context: object) -> None: context.checkpoints = [] -@when("I attempt to create a checkpoint for non-existent plan {plan_id}") +@when('I attempt to create a checkpoint for non-existent plan "{plan_id}"') def step_attempt_create_checkpoint_nonexistent_plan( context: object, plan_id: str ) -> None: -- 2.52.0 From 5ee8ae51ad829a2c2d0ce9ed29110d85ac69ecd4 Mon Sep 17 00:00:00 2001 From: CleverAgents Bot Date: Wed, 10 Jun 2026 20:23:54 -0400 Subject: [PATCH 4/4] ci: stop master workflow on PR updates Remove the stale pull_request trigger from master.yml so PR branch commits do not launch the master workflow.
