Summary

This PR addresses data integrity violations caused by redundant session.rollback() calls in repository methods that operate within the UnitOfWork (UoW) transaction pattern.

Problem

The UoW manages transactions centrally in its transaction() context manager, providing automatic rollback on exceptions. However, 58 individual repository methods were ALSO calling session.rollback() inside their exception handlers:

  1. Interference with outer UoW transactions – rollbacks in one repository undo valid changes from OTHER repositories within the same transaction
  2. Silent data loss – operations that succeeded before an exception were rolled back along with the affected operation
  3. Violation of the UoW pattern contract – domain protocol states: "All methods flush but do not commit; the caller or Unit-of-Work wrapper is responsible"

Solution

Removed all redundant rollback calls from repository methods that follow the UoW pattern (flush-only, no self-commit). Rollback responsibility is now exclusively handled by the UoW transaction context manager.

Self-committing repositories are unaffected – these manage their own complete transaction lifecycle (flush + commit + close) and retain internal rollback:

  • ToolRegistryRepository
  • ValidationAttachmentRepository
  • NamespacedProjectRepository
  • ProjectResourceLinkRepository

All agents now track which variables were explicitly present in their prompt
versus fetched from environment variables or git remote. When constructing
subagent prompts, only explicitly-present variables are included. Fetched
variables are omitted, allowing each subagent to fetch them independently.

This prevents credentials and other fetched values from being garbled as they
propagate through multiple LLM prompt layers.

Remove 58 redundant session.rollback() calls across three database
repository files that interfere with the UnitOfWork (UoW) transaction
management. Individual repository-level rollbacks caused data-integrity
violations by rolling back changes from OTHER repositories within the
same UoW transaction, resulting in silent loss of valid operations.

Rollback responsibility is now consolidated in the UoW's transaction()
context manager which handles atomicity per-transaction. Self-committing
repositories (ToolRegistryRepository, ValidationAttachmentRepository,
NamespacedProjectRepository, ProjectResourceLinkRepository) that manage
their own complete lifecycle are unaffected and retain internal rollback.

Files modified:
  - repositories.py: removed 52 rollback calls
  - changeset_repository.py: removed 5 rollback calls
  - llm_trace_repository.py: removed 1 rollback call

Code Review — PR #11054: fix(data-integrity): remove session.rollback() calls from all repository methods in UnitOfWork pattern

Overview

The core fix in this PR is technically correct and well-motivated: removing session.rollback() calls from repository methods that receive an externally-owned session via UnitOfWork constructor injection. The pattern violation was real and the solution is sound. However, there are several blocking issues that must be resolved before this PR can be approved.


What is correct

  1. Correctness of the fix - Removing rollback calls from UoW-managed repositories is the right approach. The UoW transaction() context manager correctly owns session lifecycle.
  2. Self-committing repositories preserved - ToolRegistryRepository, ValidationAttachmentRepository, NamespacedProjectRepository, and ProjectResourceLinkRepository correctly retain their rollback() calls (they own their own session lifecycle with commit + close).
  3. Commit message - Follows Conventional Changelog format, includes ISSUES CLOSED: #8179, and accurately describes the change.
  4. CHANGELOG updated - Properly documents the change in the Unreleased section.
  5. CONTRIBUTORS.md updated - Properly credits the contributor.
  6. Typecheck passes, Lint passes, Security scan passes, Integration tests pass, E2E tests pass.

BLOCKING Issues

1. CI unit_tests job is FAILING

The CI / unit_tests (pull_request) check is failing. Per project policy, all CI gates must be green before a PR can be approved or merged. The coverage job was skipped as a consequence of the unit_test failure, so coverage compliance (>=97%) cannot be confirmed.

Action required: Fix the failing unit tests, ensure coverage stays >=97%, and push a new commit. Do not force-push — push a new fix commit so CI re-runs.

2. benchmark-regression CI job is FAILING

The CI / benchmark-regression (pull_request) check is failing. Per project policy this is a required gate for PRs.

Action required: Investigate the benchmark regression and either fix the performance issue or document why this benchmark change is expected.

3. Missing BDD regression tests for the bug fix

This PR fixes a bug in issue #7489/#8179 (Type/Bug, Priority/Critical). Per the project's TDD bug fix workflow, a bug fix must include a @tdd_issue_7489 or @tdd_issue_8179 tagged BDD scenario that proves the bug existed and that the fix resolves it.

Specifically, the following are missing:

  • A Behave scenario asserting that when a repository method raises an exception, session.rollback() is NOT called on the shared UoW session
  • A scenario proving that when one repository operation fails, previously flushed writes from other repositories within the same UoW transaction are preserved (not silently rolled back)

No changes to features/ were included in this PR. This is a required-for-merge gate.

Action required: Add BDD scenarios in features/ that cover: (1) session.rollback() is not invoked on the UoW session when a repository raises OperationalError, and (2) previously flushed writes from Repository A are not lost when Repository B raises an error in the same UoW transaction. Tag them @tdd_issue_7489 per the TDD workflow.

4. Missing Type/ label

Per CONTRIBUTING.md, every PR must have exactly one Type/ label. This PR has no labels.

Action required: Add Type/Bug label to this PR.

5. Missing milestone assignment

Per CONTRIBUTING.md, every PR must be assigned to the same milestone as the linked issue. Issue #8179 is in milestone v3.2.0.

Action required: Assign milestone v3.2.0 to this PR.


Non-Blocking Suggestions

Branch naming: The branch pr_fix_8179 does not follow the project convention bugfix/mN-<descriptive-name>. The correct branch name for a bug fix on milestone v3.2.0 would be something like bugfix/m2-remove-uow-session-rollback. Non-blocking for this PR, but please follow the convention in future.

Extra commits in branch: The PR branch contains 16 commits relative to the merge base, but only 1 commit (fe0b66a2) is the actual fix. The other 15 are unrelated build: commits (agent configuration changes). The PR is currently not mergeable (mergeable: false) likely because the branch is behind master. The branch should be rebased onto master and the unrelated commits should not be included in this PR.

Suggestion (llm_trace_repository.py): In the own_session=True code path, the rollback() removal is consistent with the overall approach. The finally: s.close() handles cleanup. This is acceptable but reviewers should be aware that without explicit rollback, if s.commit() fails, the session will rely on DB-driver implicit cleanup on close.


Summary

The fix is architecturally sound and the code changes are correct. The primary blockers are: CI must pass (unit_tests + benchmark-regression), regression BDD tests must be added per the TDD bug fix workflow, and the PR needs a Type/Bug label and v3.2.0 milestone assignment. Please address these and re-request review.

Code Review — PR #11054: fix(data-integrity): remove session.rollback() calls from all repository methods in UnitOfWork pattern

Overview

The core intent of this PR is architecturally sound and well-motivated: removing session.rollback() calls from UoW-injected repository methods is the correct fix for the data integrity violation described in issue #7489. The commit message, CHANGELOG, and CONTRIBUTORS.md updates are well-done. However, there are blocking issues that prevent approval.


What is correct

  1. Architecture of the fix — Removing rollback from UoW-managed repositories is the right approach. The UoW transaction() context manager correctly owns session lifecycle.
  2. Self-committing repositories preservedNamespacedProjectRepository, ProjectResourceLinkRepository, ToolRegistryRepository, and ValidationAttachmentRepository correctly retain their rollback() calls (they own their own session lifecycle with commit + close).
  3. Commit message — Follows Conventional Changelog format. Clear, informative body.
  4. CHANGELOG.md updated — Well-written entry in the Unreleased section.
  5. CONTRIBUTORS.md updated — Properly credits the contributor.
  6. Lint, typecheck, security, integration tests, E2E tests all pass — Good baseline.

BLOCKING Issues

1. CI unit_tests job is FAILING — existing BDD test breaks

The CI / unit_tests (pull_request) check is failing. The root cause is in features/database_repository_coverage.feature — the scenario "ProjectRepository create raises database error on OperationalError" has a step:

And the session rollback should be triggered for the project create failure

The step implementation (in features/steps/container_and_repository_coverage_steps.py) asserts context.session_mock.rollback.call_count >= 1. This test verified the OLD (incorrect) behavior — rollback IS called. Now that the fix removes the rollback call, this test fails.

This existing test must be updated to reflect the new contract — it should assert that rollback is NOT called on the shared session. The test verifies the wrong invariant and must be rewritten.

Action required: Update features/database_repository_coverage.feature and its step implementation to assert that session.rollback() is NOT called on the injected session when ProjectRepository.create() fails.

2. llm_trace_repository.py — Incorrect rollback removal in own_session=True path

The fix removes s.rollback() from the except block in LLMTraceRepository.save(). However, this method has two operating modes:

  • UoW mode (session argument provided): The caller owns the session. Removing rollback is correct.
  • Standalone mode (own_session=True): The repository creates, commits, AND closes its own session — it owns the session lifecycle.

In standalone mode, if s.commit() raises, the code now skips explicit rollback and falls to finally: if own_session: s.close(). While SQLAlchemy may implicitly rollback on session close, omitting the explicit rollback in the standalone path is semantically incorrect. The self-committing repositories (NamespacedProjectRepository etc.) were correctly preserved — the same logic applies to the own_session=True branch here.

Action required: Restore s.rollback() inside the except block, guarded by if own_session: to only rollback when the repository owns the session lifecycle.

3. CI benchmark-regression job is FAILING

The CI / benchmark-regression (pull_request) check is failing. Per project policy, all CI gates must pass. This may be a pre-existing issue from unrelated benchmark commits in the branch, but it must be resolved before this PR can be merged.

Action required: Investigate and fix the benchmark regression, or if it is unrelated to the data-integrity fix, isolate those commits.

4. Missing BDD regression tests proving the bug is fixed

This PR fixes a Type/Bug / Priority/Critical issue (#7489). Per the TDD bug fix workflow, bug fixes must include @tdd_issue_7489 tagged BDD scenarios proving: (a) session.rollback() is NOT invoked on the UoW-owned session when a repository method fails, and (b) previously flushed writes from Repository A survive when Repository B raises an error in the same UoW transaction.

No changes to features/ were included in this PR's fix commit. The existing action_repository_error_handling.feature and uow_lifecycle.feature cover adjacent ground but do not carry the required @tdd_issue_7489 tag or prove the specific regression.

Action required: Add @tdd_issue_7489-tagged Behave scenarios in features/ covering the two invariants above.

5. Coverage gate was skipped

Because unit_tests failed, the CI / coverage (pull_request) job was skipped. Coverage compliance (>=97%) cannot be confirmed until unit tests pass.

Action required: Fix the unit test failures first; coverage will then run automatically.

6. Commit references ISSUES CLOSED: #8179 but #8179 is an open PR, not an issue

The commit footer says ISSUES CLOSED: #8179. However, #8179 is an open pull request (for a prior fix attempt), not a bug issue. The actual bug issue is #7489. The commit footer should reference the issue being closed.

Action required: The commit should reference ISSUES CLOSED: #7489. Add a new commit correcting this or update via rebase.

7. PR dependency direction not established

Per CONTRIBUTING.md, on the PR's Forgejo dependency list, the PR must block the linked issue (PR → blocks → issue, so that on the issue the PR appears under "depends on"). No such Forgejo dependency link exists between PR #11054 and issue #7489.

Action required: On PR #11054, add issue #7489 under the "blocks" list in Forgejo.


Non-Blocking Observations

Branch naming: pr_fix_8179 does not follow the project convention bugfix/mN-<descriptive-name>. For milestone v3.2.0 (m2), the correct name would be e.g. bugfix/m2-remove-uow-session-rollback. Non-blocking for this PR; please follow convention in future.

Unrelated commits in PR branch: The PR branch contains many unrelated commits (agent configuration changes, spec docs, benchmark additions) that predate the actual fix commit fe0b66a2. The diff shows 50 changed files / 4115 additions when the actual fix is 5 files / 58 deletions. Rebasing to isolate only the fix commit would make the PR scope clear and reduce noise.

SessionRepository / SessionMessageRepository auto_commit paths: These repositories use an auto_commit=True pattern analogous to LLMTraceRepository's own_session. The removed rollback calls cover both UoW mode and auto_commit mode. When auto_commit=True, the repository manages its own session lifecycle. Consider whether explicit rollback should be preserved under auto_commit=True, similar to the llm_trace fix suggested above.


Summary

The architectural direction is correct — UoW-injected repositories must not rollback the shared session. Blocking items to resolve: (1) fix/update the breaking BDD unit test, (2) restore rollback in llm_trace_repository standalone path, (3) fix benchmark regression, (4) add @tdd_issue_7489 regression scenarios, (5) wait for coverage gate to re-run, (6) fix issue reference in commit footer, (7) set Forgejo PR→blocks→issue dependency. Push a fix commit for each; do not force-push.

LLMTraceRepository.save() operates in two modes: UoW mode (external session injected) and standalone mode (own_session=True). The rollback removal is correct for UoW mode, but incorrect for standalone mode where this repository owns the session lifecycle.

When own_session=True and s.commit() fails, the session is left in an uncommitted state with no explicit rollback before s.close(). The self-committing repositories (NamespacedProjectRepository, ToolRegistryRepository, etc.) were correctly preserved — the same reasoning applies to this own_session=True branch.

Fix: Restore the rollback guarded by own_session:

except (SQLAlchemyDatabaseError, OperationalError) as exc:
    if own_session:
        s.rollback()  # Only rollback when we own the session lifecycle
    raise DatabaseError(f'Failed to save LLM trace: {exc}') from exc

Add BDD tests verifying the #8179 fix: repositories no longer call
session.rollback() on database errors, delegating transaction management
to the UnitOfWork pattern instead. Also fixes formatting issue in
CONTRIBUTORS.md (removed stray << prefix from line).

BDD scenarios verify:
- Database errors propagate through repositories without swallowing
- Cross-repository atomicity preserved within UoW transactions
- Mock-based verification that repo error handlers don't call rollback
- UoW owns session rollback exclusively

Re-Review — PR #11054: fix(data-integrity): remove session.rollback() calls from all repository methods in UnitOfWork pattern

New commit since last review

Commit 476d7bb7test(bdd): add repository error handling rollback cleanup scenarios — was added as a response to the previous REQUEST_CHANGES review. This re-review evaluates whether the prior blocking items were addressed and assesses the new code.


Prior feedback — status summary

Blocker from review #8257 Addressed?
1. unit_tests CI failing (existing BDD test asserts OLD rollback behavior) Not fixed
2. llm_trace_repository.py — rollback incorrectly removed from own_session=True path Not fixed
3. benchmark-regression CI failing Not fixed
4. Missing @tdd_issue_7489 BDD regression tests ⚠️ Partially addressed (wrong tag; broken tests)
5. Coverage gate skipped (depends on unit_tests) Not resolved
6. Commit footer references #8179 (a PR) instead of #7489 (the bug issue) Not fixed
7. PR dependency direction (PR must block issue in Forgejo) Not established

BLOCKING Issues

1. CI unit_tests STILL FAILING — the root cause was not fixed

The previous review identified that features/steps/container_and_repository_coverage_steps.py (around line 383) has a step step_verify_create_rollback that asserts:

assert context.session_mock.rollback.call_count >= 1

This step is used by the scenario "ProjectRepository create raises database error on OperationalError" in features/database_repository_coverage.feature:45 (And the session rollback should be triggered for the project create failure). The new commit did not update this step — it still asserts the OLD (broken) behavior. Unit tests are still failing for exactly this reason. The new feature file adds NEW tests but does not fix the EXISTING broken assertion.

Action required: Update features/steps/container_and_repository_coverage_steps.pystep_verify_create_rollback() to assert context.session_mock.rollback.assert_not_called() instead of call_count >= 1.

2. llm_trace_repository.py — standalone own_session=True path still missing explicit rollback

The save() method in llm_trace_repository.py still has no if own_session: s.rollback() in the except block. When operating in standalone mode (own_session=True), if s.commit() raises, the exception propagates and finally: if own_session: s.close() runs — but without an explicit s.rollback(). While SQLAlchemy may implicitly rollback on close, this is semantically incorrect and inconsistent with the self-committing repository pattern used by ToolRegistryRepository, ValidationAttachmentRepository, etc. (which were correctly preserved).

The fix from the previous review was:

except (SQLAlchemyDatabaseError, OperationalError) as exc:
    if own_session:
        s.rollback()  # Only rollback when we own the session lifecycle
    raise DatabaseError(f"Failed to save LLM trace: {exc}") from exc

This was not implemented.

Action required: Restore s.rollback() guarded by if own_session: in the except block of llm_trace_repository.py:save().

3. New BDD step file has critical runtime bugs (ctx vs context)

The new file features/steps/database_repo_error_handling_steps.py uses ctx as if it were a module-level variable in multiple places, but ctx is not defined. The Behave step context is always the context parameter passed to each step function. Every occurrence of ctx.xxx must be context.xxx. Affected lines:

  • step_impl_attempt_project_create_fails: ctx._err_result = ...context._err_result = ...
  • step_impl_attempt_action_create_fails: ctx._err_result = ...context._err_result = ...
  • step_impl_create_action_in_uow: ctx._action_repo_mock = ... → should be context._action_repo_mock = ...
  • step_impl_create_multiple_actions (first definition): ctx._multi_action_repo = ...context._multi_action_repo = ...
  • step_impl_project_creation_fails_in_uow: ctx._err = ...context._err = ...
  • step_impl_create_action_success: ctx._multi_repo_session = ...context._multi_repo_session = ...
  • step_impl_trigger_db_error_in_repo: ctx._err = ...context._err = ...

These will cause NameError: name ctx is not defined at runtime, crashing the BDD test run.

Action required: Replace every ctx.xxx with context.xxx in database_repo_error_handling_steps.py.

4. Duplicate @given step definition causes Behave AmbiguousStep error

The step "I create multiple actions successfully (flushed but not committed)" is decorated with @given(...) TWICE — once in step_impl_create_multiple_actions and again in step_impl_create_actions_success. Behave will raise AmbiguousStep and refuse to run any scenario that uses this step.

Action required: Remove the duplicate step_impl_create_actions_success function (the second @given("I create multiple actions successfully...") definition). The first definition should stand.

5. # type: ignore[import-untyped] in new step file — project prohibits ALL # type: ignore comments

The new file contains:

from behave import given, then, when  # type: ignore[import-untyped]

Per CONTRIBUTING.md, zero # type: ignore comments are tolerated anywhere in the codebase. Pyright strict type checking is enforced.

Action required: Remove the # type: ignore[import-untyped] comment. Add a Pyright stub or configure Pyright to suppress the missing stubs at the project configuration level rather than inline.

6. OperationalError imported but unused in new step file

from sqlalchemy.exc import IntegrityError, OperationalError

OperationalError is never referenced anywhere in database_repo_error_handling_steps.py. This will trigger a F401 unused import violation from ruff, which is one of the reasons the lint CI job is FAILING.

Action required: Remove OperationalError from the import (or use it somewhere meaningful).

7. CI lint job is NOW FAILING (regression from prior review)

The lint CI job is now failing (Failing after 1m12s). This is a new regression introduced by the new commit (the prior review confirmed lint was passing). The unused import and other formatting issues in the new step file are likely contributing to this failure. All required CI gates must be green before approval.

Action required: Fix lint failures. Run nox -s lint locally and resolve all violations before pushing.

8. CI e2e_tests job is NOW FAILING (regression from prior review)

The e2e_tests CI job is now failing. It was passing in the previous round of CI. While this may be a pre-existing flakiness issue or infrastructure issue, any CI failure on a required gate is blocking. The relationship to the new commit must be investigated.

Action required: Investigate the e2e_tests failure. If introduced by this PR, fix it. If pre-existing infrastructure flakiness, document this clearly and request a re-run.

9. BDD tag is @tdd_issue_8179 but should be @tdd_issue_7489

The new feature file is tagged @tdd_issue_8179, but #8179 is an open PR (the previous fix attempt), not the bug issue. The actual bug issue is #7489. Per the TDD bug fix workflow, the tag must reference the ISSUE number, not a PR number.

Action required: Change @tdd_issue_8179 to @tdd_issue_7489 in database_repository_error_handling.feature.

The new commit 476d7bb7 has footer: ISSUES CLOSED: #8179, #10451. #8179 is an open PR, not an issue. As flagged in the previous review, the correct issue reference is #7489. #10451 was not mentioned in the PR description or linked issue chain — it is unclear what this refers to.

Action required: The commit footer must reference ISSUES CLOSED: #7489 (and optionally ISSUES CLOSED: #10451 if that issue is genuinely being closed by this work, with verification).

11. PR dependency direction not established

As flagged in the previous review, the PR must show issue #7489 under its "blocks" list in Forgejo. This creates the correct dependency direction (PR → blocks → issue). No Forgejo dependency link has been established.

Action required: On PR #11054 in Forgejo, add issue #7489 under the "blocks" list.

12. Coverage gate still skipped

Because unit_tests is failing, the coverage CI job was skipped (Has been skipped). Coverage compliance (≥ 97%) cannot be confirmed.

Action required: Fix the unit_tests failure (items 1, 3, 4 above); the coverage gate will then run automatically.


What IS correctly addressed

  1. The core fix in repositories.py, changeset_repository.py, and llm_trace_repository.py (UoW mode) remains correct and architecturally sound — removing rollback from non-session-owning repository methods is the right fix.
  2. Self-committing repositories (ToolRegistryRepository, ValidationAttachmentRepository, NamespacedProjectRepository, ProjectResourceLinkRepository) correctly retain their rollback calls.
  3. The intent of the new BDD feature file is correct — testing that session.rollback() is NOT called by repositories when errors occur, and that the UoW owns rollback exclusively.
  4. CHANGELOG.md and CONTRIBUTORS.md (formatting fix in the new commit) are updated.
  5. typecheck, security, integration_tests are passing.

Non-Blocking Observations

Branch naming: pr_fix_8179 still does not follow project convention bugfix/mN-<name>. Non-blocking for this PR but please follow convention in future PRs.

Unrelated commits in branch: The PR branch contains many unrelated commits (agent config changes, spec docs, benchmark work, etc.) that are not part of this data-integrity fix. This makes the diff appear to touch 52 files when the actual fix is 5 files. Rebasing to isolate the fix + test commits would clarify the scope. Non-blocking but recommended.

Suggestion — test quality: The cross-repository atomicity scenarios (@cross_repo_commit_preservation, @cross_repo_rollback_via_uow) use mock-based assertions rather than real SQLAlchemy session tracking. While this is pragmatic for isolation, consider adding at least one integration-style test using a real in-memory SQLite DB with actual table schema to verify the UoW behavior end-to-end once the schema is set up correctly (e.g. using create_all() in the Background step).


Summary

The new commit (476d7bb7) adds BDD tests with the right intent but introduces multiple blocking defects: critical ctx/context naming bugs that will crash tests at runtime, a duplicate step definition causing Behave AmbiguousStep, a prohibited # type: ignore comment, an unused import, and a wrong TDD tag. Additionally, the two most important prior blockers remain unaddressed: the existing broken step assertion (the root cause of the ongoing unit_tests CI failure) and the missing own_session rollback guard in llm_trace_repository.py. lint and e2e_tests are now also failing (new regressions). Please address all 12 blockers above and push a new fix commit. Do not force-push.

BLOCKING — Existing assertion still verifies OLD (incorrect) rollback behavior — root cause of unit_tests CI failure (unresolved from prior review)

This step was flagged as blocking in review #8257. step_verify_create_rollback() still asserts:

assert context.session_mock.rollback.call_count >= 1

This asserts the OLD (pre-fix) behavior: that ProjectRepository.create() calls session.rollback() when it catches a database error. After the fix removes rollback from repository error handlers, this assertion will always fail — which is why unit_tests has been failing since the first commit of this PR.

Required fix:

@then("the session rollback should be triggered for the project create failure")
def step_verify_create_rollback(context):
    """Verify session rollback is NOT called by the repo (UoW owns this)."""
    context.session_mock.rollback.assert_not_called()

OR, if keeping the old scenario name feels confusing, rename the scenario in the feature file to "ProjectRepository create raises database error and does NOT call rollback (UoW owns rollback)" and update the step text accordingly.

This is a ruff `F401` violation and is likely contributing to the `lint` CI failure. **Fix:** Remove `OperationalError` from the import: ```python from sqlalchemy.exc import IntegrityError ``` --- Automated by CleverAgents Bot Supervisor: PR Review | Agent: pr-review-worker

BLOCKING — ctx is not defined; must be context

ctx._err_result will raise NameError: name 'ctx' is not defined at runtime. The Behave step context is the context parameter, not a module-level ctx variable.

Fix:

context._err_result = context.project_repo.create(
    Project(name="duplicate-project", namespace="global"),
)

Same issue applies to all subsequent occurrences of ctx.xxx in this file — replace every ctx.xxx with context.xxx.

BLOCKING — Duplicate @given step definition causes Behave AmbiguousStep error

The step "I create multiple actions successfully (flushed but not committed)" is registered with @given(...) for the SECOND time here (the first registration is around line 95 in step_impl_create_multiple_actions). Behave treats this as an ambiguous step and will refuse to run any scenario that uses it.

Fix: Remove this duplicate @given(...) decorator and function, or rename one of the steps so they have distinct text.

BLOCKING — Missing if own_session: s.rollback() in standalone path (unresolved from prior review)

This issue was flagged as blocking in review #8257 and has not been addressed. The except block has no explicit rollback when own_session=True. When s.commit() fails in standalone mode, the session is closed without an explicit rollback, which is semantically incorrect.

Required fix (as specified in the previous review):

except (SQLAlchemyDatabaseError, OperationalError) as exc:
    if own_session:
        s.rollback()  # Only rollback when we own the session lifecycle
    raise DatabaseError(f"Failed to save LLM trace: {exc}") from exc

This mirrors the pattern used by ToolRegistryRepository, ValidationAttachmentRepository, and other self-committing repositories that were correctly preserved in this PR.
