brent.edwards	01b6eb1804	feat(autonomy): parallel execution scales to 10+ concurrent subplans (#1201) ... ## Summary Add M6 parallel-scaling coverage for 10+ concurrent subplans: - **15-subplan parallel scenario** with explicit peak-concurrency bound checks (`max_parallel=10`) and thread-safe concurrency tracking via `_build_executor()`. - **Deep hierarchical decomposition** coverage (4+ levels) with adjusted leaf condition that only stops early when hitting `max_depth` or when the workset is trivially small (`min_files_per_subplan`). - **Non-progress guard** in `_build_hierarchy` to prevent pathological recursion when clustering cannot meaningfully split the file set. - **Small-project regression test** (< 50 files) verifying decomposition depth does not increase unexpectedly with the relaxed leaf condition. - **ASV benchmark** for 15-subplan parallel execution with `max_parallel=10` to track scaling behavior. ### Removed from this PR The `_build_hierarchy` child-linkage correctness fix (returning `node_id` from recursive calls instead of using `nodes[-1].node_id`) has been **removed** per review feedback — it is a separate bug fix and will be submitted as an independent issue/PR per CONTRIBUTING.md §Atomic Commits. ## Approach - **Concurrency tracking:** The `_build_executor()` closure in step definitions detects `context.concurrency_counter` / `context.concurrency_lock` and performs thread-safe peak tracking in a try/finally block. - **Leaf condition:** Replaced the `max_files_per_subplan` / `max_tokens_per_subplan` leaf check with a `min_files_per_subplan` check to allow deeper decomposition for large projects. Added a non-progress guard so clustering that cannot split the file set terminates immediately rather than recursing to `max_depth`. - **Deterministic IDs:** `_ids_for_count()` preserves legacy fixed IDs for the first 5 subplans and generates additional deterministic IDs for scale scenarios. ## Validation ### Passing - `nox -s lint` — all checks passed - `nox -s typecheck` — 0 errors, 0 warnings - `nox -s unit_tests` — 12,988 scenarios passed, 0 failed - `nox -s coverage_report` — 97% (passes `--fail-under=97`) Closes #855 Reviewed-on: #1201 Co-authored-by: Brent E.

freemo	6519f140a9	feat(context): add hot/warm/cold tiers and actor views ... Implement hot/warm/cold context tiers with ContextTier, ActorRole, TieredFragment, TierBudget, ActorContextView, TierMetrics, and ScopedBackendView models. ContextTierService provides store/get, promotion/demotion with cold-tier summarisation hook, LRU eviction, per-actor filtered views (strategist/executor/reviewer), and project-scoped isolation via ScopedBackendView. Settings: context_max_tokens_hot, context_max_decisions_warm, context_max_decisions_cold. DI-wired as singleton context_tier_service. Includes Behave BDD scenarios (30), Robot Framework integration tests (7), ASV benchmarks (5 suites), and docs/reference/context_tiers.md. Closes #208	2026-03-03 17:01:57 +00:00
Luis Mendes	9f6fb667c2	feat(subplan): execute and merge subplans ... Implement SubplanExecutionService and SubplanMergeService to enable parent plans to decompose work into coordinated child subplans with configurable execution modes (sequential, parallel, dependency-ordered) and merge strategies (git_three_way, sequential_apply, fail_on_conflict, last_wins). - SubplanExecutionService: schedules subplan execution with retry support via SubplanFailureHandler, max_parallel limits, fail_fast semantics, and topological DAG ordering for dependency mode - SubplanMergeService: wraps sandbox merge infrastructure to combine subplan sandbox outputs using the configured merge strategy - BDD tests: 21 scenarios covering all execution modes, merge strategies, validation, and integration flows - Robot tests: 11 integration test cases with helper module - ASV benchmarks: performance benchmarks for execution and merge - Documentation: reference guide in docs/reference/subplans.md ISSUES CLOSED: #184	2026-03-01 09:07:06 +00:00
