Metadata

Branch: fix/repo-utc-datetime
Commit Message: fix(infra): use UTC-aware datetime in repository update methods
Milestone: v3.7.0
Parent Epic: N/A — no suitable infrastructure Epic exists; linked to v3.7.0 milestone

Description

Several repository update() methods use datetime.now() (timezone-naive) to set updated_at timestamps, while the domain models use datetime.now(tz=UTC) (timezone-aware). This creates a timezone inconsistency where timestamps written by repository updates are naive (no timezone info) while timestamps from domain model defaults are UTC-aware.

What was tested: Code-level analysis of src/cleveragents/infrastructure/database/repositories.py and runtime verification.

Expected Behavior

All updated_at timestamps written by repository methods should be UTC-aware (using datetime.now(UTC) or datetime.now(tz=UTC)), consistent with the domain model defaults.

Actual Behavior

The following repository methods use datetime.now() (naive):

ProjectRepository.update() (line ~232): db_project.updated_at = datetime.now()
PlanRepository.update() (line ~328): db_plan.updated_at = datetime.now()
ChangeRepository.mark_applied() (line ~594): {"applied": True, "applied_at": datetime.now()}
ActorRepository.upsert() (line ~762): existing.updated_at = datetime.now()
ActorRepository.clear_default() (line ~809): {"is_default": False, "updated_at": datetime.now()}
ActorRepository.set_default() (line ~821): db_actor.updated_at = datetime.now()
ActionRepository.update() (line ~1098): row.updated_at = datetime.now().isoformat()

Runtime verification:

# After calling ProjectRepository.update():
fetched = ctx.projects.get_by_id(project_id)
print(fetched.updated_at.tzinfo)  # None — timezone-naive!

The domain models use UTC-aware defaults:

# In project.py:
updated_at: datetime = Field(
    default_factory=lambda: datetime.now(tz=UTC),  # UTC-aware
)

Impact

Timestamps written by update() methods are timezone-naive, while timestamps from create() operations (which use domain model defaults) are UTC-aware.
Comparing created_at (UTC-aware) with updated_at (naive) will raise TypeError: can't compare offset-naive and offset-aware datetimes in Python.
Sorting or filtering by timestamps across create/update operations may produce incorrect results.

Code location: src/cleveragents/infrastructure/database/repositories.py

Steps to Reproduce

from cleveragents.infrastructure.database.unit_of_work import UnitOfWork
from cleveragents.domain.models.core import Project, ProjectSettings
from pathlib import Path

uow = UnitOfWork("sqlite:///:memory:", require_confirmation=False)
uow.init_database()

with uow.transaction() as ctx:
    project = Project(name="test", path=Path("/tmp"), settings=ProjectSettings())
    created = ctx.projects.create(project)
    created.name = "updated"
    ctx.projects.update(created)
    fetched = ctx.projects.get_by_id(created.id)
    print(fetched.updated_at.tzinfo)  # None — should be UTC

Subtasks

Fix ProjectRepository.update() — replace datetime.now() with datetime.now(UTC)
Fix PlanRepository.update() — replace datetime.now() with datetime.now(UTC)
Fix ChangeRepository.mark_applied() — replace datetime.now() with datetime.now(UTC)
Fix ActorRepository.upsert() — replace datetime.now() with datetime.now(UTC)
Fix ActorRepository.clear_default() — replace datetime.now() with datetime.now(UTC)
Fix ActorRepository.set_default() — replace datetime.now() with datetime.now(UTC)
Fix ActionRepository.update() — replace datetime.now() with datetime.now(UTC)
Add/update unit tests to assert tzinfo is not None on timestamps returned after update() calls
Verify no other repository methods use timezone-naive datetime.now()

Definition of Done

All 7 identified datetime.now() calls in repositories.py replaced with datetime.now(UTC)
updated_at / applied_at timestamps returned after any repository update() call are UTC-aware (tzinfo is not None)
Comparing created_at and updated_at on the same domain object does not raise TypeError
Regression tests added covering UTC-awareness of timestamps after update operations
All nox stages pass
Coverage >= 97%

⚠️ Orphan Issue — Manual Linking Required

This issue was created without a parent Epic because no suitable infrastructure/repository Epic currently exists in the open issues list. The only open Epic is #1678 (CI Execution Time Optimization), which is unrelated to this bug.

Action required: A project maintainer should either:

Link this issue to an existing or newly created infrastructure Epic, or
Create a new Epic for "Infrastructure / Repository Layer Correctness" and link this issue as a child (this issue should block the parent Epic).

Per CONTRIBUTING.md, orphan issues are not permitted. This issue has been assigned to milestone v3.7.0 as a temporary anchor until a parent Epic is identified.
