Delete branch "fix/wire-subplan-execution-service"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Wire subplan_service from the DI container into _get_plan_executor() so PlanExecutor can spawn child plans during the Execute phase. When SubplanService is available but SubplanExecutionService is not explicitly injected, _execute_subplans() now lazily creates a SubplanExecutionService on-the-fly using the parent plan's subplan_config and the new _execute_child_plan callback.
Changes
Closes #10268
ad186d146a46590a943cReview Summary
Thank you for this PR — the intent is correct and the wiring approach is sound. However there are 6 blocking issues that must be resolved before this can be approved. The most critical are the TDD workflow violations and the broken BDD test structure.
🔴 Blocking Issues
1. TDD bug-fix workflow not followed — missing
@tdd_issue_10268tagsThis is a
Type/Bugfix. The mandatory TDD workflow requires:Type/Testingissue created before any code was written.tdd/mN-<name>branch with a Behave scenario tagged@tdd_issue + @tdd_issue_10268 + @tdd_expected_failmerged into master first.@tdd_expected_failand the CI gate verifies the tag is absent and the@tdd_issue_10268test exists.The feature file added (
plan_execution_hierarchical.feature) carries tags@mock_only @subplan @plan_executor @issue_10268— none of the three required TDD tags are present. CI will block on the missing@tdd_issue_10268regression guard.Please clarify: was the TDD issue-capture test merged separately? If so, point to that commit. If not, the full TDD workflow must be executed before this PR can proceed.
2. Branch name does not follow convention
Current branch:
fix/wire-subplan-execution-serviceRequired convention for bug fixes:
bugfix/mN-<name>where N is the milestone number. Milestonev3.5.0→ N = 5. Branch should be:The prefix
fix/is not a valid branch type in this project (feature/,bugfix/,tdd/are the three allowed prefixes).3. Forgejo dependency direction missing
The PR body says
Closes #10268but the Forgejo dependency link has not been set. The PR must appear under "depends on" on issue #10268, meaning on this PR you must add issue #10268 under "blocks".Without this link the dependency tracking is broken and the PR cannot be auto-closed against the issue on merge.
4. BDD test is structurally broken —
Thenstep re-executes the plan inside the patchIn
features/steps/plan_execution_hierarchical_steps.py(theThenstep for lazy creation):The
Whenstep has already calledrun_execute. ThisThenstep calls it again inside thepatch.objectcontext. The patch was never active during theWhenexecution — theassert_called_once()passes trivially because it tests a second execution triggered entirely within theThenstep. This test does not verify what it claims.The correct pattern is: patch before the
Whenstep triggers execution (e.g. in aGivenor fixture), then assert inThenwithout re-running.5.
@whenstep definition is missingThe feature file declares:
But the steps file contains only
@givenand@thendecorators — there is no@whenstep defined for this sentence. Behave will reportundefined stepand the scenario will fail to run entirely.6. CHANGELOG not updated
No entry has been added to
CHANGELOG.mdfor this commit. Per project contribution rules, one changelog entry per commit is required. Please add an entry under## [Unreleased].🟠 Code Quality Issues (blocking merge, should be fixed in this PR)
7. Lazy
SubplanExecutionServicecreation permanently mutates instance stateThe service is created from the first plan's
subplan_configand stored onself. IfPlanExecutoris reused across multiple plan executions (which DI-wired instances typically are), subsequent plans will silently reuse the stale service built from the first plan's config. This is a state leak. Consider creating the service locally (not assigning toself) or guarding with the plan ID.8. No recursion guard in
_execute_child_planrun_execute→_execute_subplans→_execute_child_plan→run_execute(child). If a child plan has its own subplans, this recurses unboundedly. A misconfigured plan graph could cause a stack overflow. A depth counter or a seen-plan-IDs set should be added.9. Strategize result is not checked before proceeding to execute
If
run_strategizecompletes without raising but leaves the plan in a non-executable state (failed strategy, missing decisions, etc.),run_executeproceeds regardless. Only exceptions are caught — a silent strategy failure will producesuccess=Truewith an empty changeset.10. Inline imports inside methods violate project import rules
Project rules require all imports at the top of the file. The only permitted exception is
if TYPE_CHECKING:for type-hint-only imports. If these are runtime-circular, restructure to avoid the cycle rather than using inline imports.🟡 Metadata Issues

46590a943cbb1f88de83Re-Review: PR #11246 — 4 Blocking Issues Remain
Thank you for addressing hamza.khyari's feedback. Significant progress was made — 8 of 12 items are now resolved. However, 4 blocking issues remain and must be addressed before this PR can be approved.
✅ Resolved Items
🔴 Remaining Blocking Issues
1. TDD workflow not followed — @tdd_issue_10268 tags still missing
The feature file carries tags @mock_only @subplan @plan_executor @issue_10268. The required TDD triple-tag system is NOT present: @tdd_issue, @tdd_issue_10268, and @tdd_expected_fail are all absent.
Per the project's TDD bug-fix workflow: a companion Type/Testing issue must be created, a tdd/m5- branch with a Behave scenario tagged @tdd_issue + @tdd_issue_10268 + @tdd_expected_fail must be merged into master BEFORE this fix PR, and then this PR removes @tdd_expected_fail while keeping @tdd_issue_10268 as the regression guard.
Action required: Either (a) confirm the TDD issue-capture branch was merged separately and point to that commit, or (b) execute the full TDD workflow.
2. Branch name is invalid — must use bugfix/m5- prefix
Current branch: fix/wire-subplan-execution-service
Per the branch naming rules, bug fixes must use the bugfix/mN- format where N is the milestone number. v3.5.0 → N=5.
Required: bugfix/m5-wire-subplan-execution-service
The fix/ prefix is not in the list of valid branch types (feature/, bugfix/, tdd/ are the three allowed prefixes).
3. @when step definition is missing — scenario will fail at runtime
The feature file declares: When I call run_execute on the parent plan
But features/steps/plan_execution_hierarchical_steps.py contains ONLY @given and @then decorators — there is no @when step defined. When Behave runs, it will report no step definition and the scenario will fail to execute.
Action required: Add a @when step definition, e.g.:
@when("I call run_execute on the parent plan")
def step_when_call_run_execute(context: Context) -> None:
context.executor.run_execute(context.plan.identity.plan_id)
Note: context.executor and context.plan are set up by the Given step, so the When step simply calls run_execute and the Then step asserts that execute_all was called.
4. Forgejo dependency direction — could not be independently verified
Issue #10268 shows pull_request: null in the API response. While the PR body says Closes #10268 (which creates a close-link), the specific Forgejo dependency link (PR blocks issue #10268) could not be confirmed.
Action required: Confirm the dependency is set — on the PR, issue #10268 should appear under depends on.
Summary
CI status: All 12 checks green
Please address items 1, 2, and 3 and re-request review. Item 4 needs only confirmation.

1. Branch name (
fix/…vsbugfix/m5-…)hamza.khyari #2, brent.edwards #2 — Skipped.
The issue Metadata (issue #10268) explicitly states:
Per CONTRIBUTING.md: "The branch MUST match the Branch field in the issue's ## Metadata section verbatim." The current branch name matches the prescribed Metadata exactly. Renaming would contradict the Metadata, which is the authoritative source for branch naming.

The step
When I call run_execute on the parent planalready exists infeatures/steps/plan_executor_subplan_spawning_steps.py:402. Behave discovers step definitions across all.pyfiles underfeatures/steps/. Both feature files (plan_execution_hierarchical.featureandplan_executor_subplan_spawning.feature) share this step. All 702 feature suites pass (nox -s unit_tests— 0 failures, 0 errors). Adding a duplicate definition would be redundant.3. Forgejo dependency link
