Commit: fix: replace session.commit() with session.flush() in LLMTraceRepository.save()
Branch: fix/llm-trace-repository-session-commit

Background and Context

LLMTraceRepository.save() in src/cleveragents/infrastructure/database/llm_trace_repository.py calls session.commit() directly, violating the session-factory pattern (ADR-007) and breaking transaction atomicity when used within a UnitOfWork.transaction() context.

All other session-factory repositories (ActionRepository, LifecyclePlanRepository, ChangeSetEntryRepository, ToolInvocationRepository) correctly call only session.flush() and leave commit responsibility to the caller. LLMTraceRepository is the sole exception and is inconsistent with the established pattern.

Steps to Reproduce

Use LLMTraceRepository within a UnitOfWork.transaction() context alongside other repository operations.
Call llm_trace_repo.save(trace) — this immediately commits the entire transaction.
If a subsequent operation raises an exception, the outer UnitOfWork.transaction() calls session.rollback(), but the LLM trace data is already committed and cannot be rolled back.

Minimal example:

with uow.transaction() as ctx:
    plan = ctx.lifecycle_plans.create(plan_obj)   # flush only
    llm_trace_repo.save(trace)                     # ← commits entire transaction here!
    raise SomeError()                              # outer rollback cannot undo the trace

Actual Behavior

LLMTraceRepository.save() calls session.commit() at line:

# src/cleveragents/infrastructure/database/llm_trace_repository.py
session.add(model)
session.commit()   # ← direct commit, violates session-factory contract

The LLM trace is committed to the database even if the enclosing transaction is later rolled back, creating orphaned trace records for failed operations.

Expected Behavior

LLMTraceRepository.save() should call session.flush() (not session.commit()), consistent with all other session-factory repositories. The caller or UnitOfWork wrapper is responsible for committing the transaction.

The class docstring already states: "Callers are responsible for commit" — the implementation contradicts this contract.

Acceptance Criteria

LLMTraceRepository.save() calls session.flush() instead of session.commit()
The class docstring remains accurate (callers are responsible for commit)
Existing tests for LLMTraceRepository pass
A new test verifies that save() does not commit the session
A new integration test verifies that LLM traces are rolled back when the enclosing UnitOfWork transaction rolls back
nox passes with coverage ≥ 97%

Subtasks

Change session.commit() to session.flush() in LLMTraceRepository.save() (src/cleveragents/infrastructure/database/llm_trace_repository.py)
Add unit test asserting save() does not call session.commit()
Add integration test verifying rollback propagation through UnitOfWork
Verify no other callers of LLMTraceRepository.save() rely on the auto-commit behaviour

Definition of Done

This issue should be closed when:

LLMTraceRepository.save() uses session.flush() instead of session.commit()
Transaction atomicity is preserved when LLMTraceRepository is used within a UnitOfWork context
All acceptance criteria above are verified by passing tests
nox passes with coverage ≥ 97%

## Metadata - **Commit**: `fix: replace session.commit() with session.flush() in LLMTraceRepository.save()` - **Branch**: `fix/llm-trace-repository-session-commit` ## Background and Context `LLMTraceRepository.save()` in `src/cleveragents/infrastructure/database/llm_trace_repository.py` calls `session.commit()` directly, violating the session-factory pattern (ADR-007) and breaking transaction atomicity when used within a `UnitOfWork.transaction()` context. All other session-factory repositories (`ActionRepository`, `LifecyclePlanRepository`, `ChangeSetEntryRepository`, `ToolInvocationRepository`) correctly call only `session.flush()` and leave commit responsibility to the caller. `LLMTraceRepository` is the sole exception and is inconsistent with the established pattern. ## Steps to Reproduce 1. Use `LLMTraceRepository` within a `UnitOfWork.transaction()` context alongside other repository operations. 2. Call `llm_trace_repo.save(trace)` — this immediately commits the entire transaction. 3. If a subsequent operation raises an exception, the outer `UnitOfWork.transaction()` calls `session.rollback()`, but the LLM trace data is already committed and cannot be rolled back. **Minimal example**: ```python with uow.transaction() as ctx: plan = ctx.lifecycle_plans.create(plan_obj) # flush only llm_trace_repo.save(trace) # ← commits entire transaction here! raise SomeError() # outer rollback cannot undo the trace ``` ## Actual Behavior `LLMTraceRepository.save()` calls `session.commit()` at line: ```python # src/cleveragents/infrastructure/database/llm_trace_repository.py session.add(model) session.commit() # ← direct commit, violates session-factory contract ``` The LLM trace is committed to the database even if the enclosing transaction is later rolled back, creating orphaned trace records for failed operations. ## Expected Behavior `LLMTraceRepository.save()` should call `session.flush()` (not `session.commit()`), consistent with all other session-factory repositories. The caller or `UnitOfWork` wrapper is responsible for committing the transaction. The class docstring already states: *"Callers are responsible for commit"* — the implementation contradicts this contract. ## Acceptance Criteria - [x] `LLMTraceRepository.save()` calls `session.flush()` instead of `session.commit()` - [x] The class docstring remains accurate (callers are responsible for commit) - [x] Existing tests for `LLMTraceRepository` pass - [x] A new test verifies that `save()` does not commit the session - [x] A new integration test verifies that LLM traces are rolled back when the enclosing `UnitOfWork` transaction rolls back - [x] `nox` passes with coverage ≥ 97% ## Subtasks - [x] Change `session.commit()` to `session.flush()` in `LLMTraceRepository.save()` (`src/cleveragents/infrastructure/database/llm_trace_repository.py`) - [x] Add unit test asserting `save()` does not call `session.commit()` - [x] Add integration test verifying rollback propagation through `UnitOfWork` - [x] Verify no other callers of `LLMTraceRepository.save()` rely on the auto-commit behaviour ## Definition of Done This issue should be closed when: 1. `LLMTraceRepository.save()` uses `session.flush()` instead of `session.commit()` 2.

Implementation Attempt — Tier 1: haiku — Success

Implemented the fix for LLMTraceRepository.save() calling session.commit() instead of session.flush().

Changes made:

Changed session.commit() to session.flush() in LLMTraceRepository.save() in src/cleveragents/infrastructure/database/llm_trace_repository.py
Added 2 new BDD scenarios to features/llm_trace.feature:
- "Repository save() calls flush not commit" — verifies save() uses flush not commit
- "LLM trace rolled back when UnitOfWork transaction rolls back" — verifies rollback propagation
Added corresponding step definitions to features/steps/llm_trace_steps.py

Quality gates:

lint ✓
typecheck ✓
unit_tests ✓ (47 scenarios pass, including 2 new ones)
