Metadata

Branch: fix/sandbox-manager-type-ignore
Commit Message: fix(sandbox): remove type: ignore in SandboxManager strategy assignment
Milestone: v3.7.0
Parent Epic: #362

Background and context

The project's coding standards (CONTRIBUTING.md) strictly forbid the use of # type: ignore comments:

"The use of # type: ignore or any other mechanism to suppress type-checking errors is strictly forbidden."

A # type: ignore[assignment] comment was discovered in src/cleveragents/infrastructure/sandbox/manager.py at line 618, inside the get_or_create_sandbox_for_resource method. This violates the project's no-type-suppression policy and must be resolved with a proper type-safe fix.

Current behavior (for bugs)

src/cleveragents/infrastructure/sandbox/manager.py, line 618, method get_or_create_sandbox_for_resource, contains:

# Determine strategy from the boundary resource.
strategy: SandboxStrategyStr = "none"
if boundary_resource.sandbox_strategy is not None:
    strategy = boundary_resource.sandbox_strategy  # type: ignore[assignment]

The root cause is a type mismatch: boundary_resource.sandbox_strategy is of type SandboxStrategy | None (a StrEnum), while strategy is declared as SandboxStrategyStr (a Literal["git_worktree", "copy_on_write", "transaction_rollback", "snapshot", "overlay", "none"]). These are structurally compatible at runtime (both are strings with the same values), but Pyright cannot verify this without an explicit cast or conversion — hence the suppression comment.

Code location: src/cleveragents/infrastructure/sandbox/manager.py, line 618, method get_or_create_sandbox_for_resource

Expected behavior

The # type: ignore[assignment] comment must be removed. The assignment must be made type-safe using an explicit cast or conversion, for example:

strategy = SandboxStrategyStr(boundary_resource.sandbox_strategy)

Or better, a proper conversion/validation function that maps SandboxStrategy → SandboxStrategyStr explicitly, ensuring the two types cannot silently diverge in the future.

The file must pass nox -e typecheck (Pyright) with zero errors and zero suppression comments.

Acceptance criteria

# type: ignore[assignment] at line 618 of manager.py is removed
The assignment is replaced with a type-safe explicit cast or conversion
nox -e typecheck passes with zero errors on the modified file
No new # type: ignore comments are introduced anywhere in the fix

Supporting information

Violates: CONTRIBUTING.md — "The use of # type: ignore or any other mechanism to suppress type-checking errors is strictly forbidden."
File: src/cleveragents/infrastructure/sandbox/manager.py
Method: get_or_create_sandbox_for_resource
Line: 618
Type mismatch: SandboxStrategy (StrEnum) vs SandboxStrategyStr (Literal[...]) — structurally compatible but not statically verifiable without a cast
Runtime impact: None — the code works correctly at runtime since SandboxStrategy values are a subset of SandboxStrategyStr values. However, the suppression hides potential future type errors if the two types diverge.

Subtasks

Locate and confirm the # type: ignore[assignment] at manager.py line 618
Implement a type-safe conversion from SandboxStrategy to SandboxStrategyStr (e.g., explicit cast via SandboxStrategyStr(...) or a dedicated helper function)
Remove the # type: ignore[assignment] comment
Write a Behave scenario in features/ that exercises get_or_create_sandbox_for_resource with a non-None sandbox_strategy to ensure the conversion path is covered
Run nox -e typecheck — confirm zero errors
Run nox -e unit_tests — confirm all scenarios pass
Run nox -e coverage_report — confirm coverage ≥ 97%
Run nox (all default sessions) — fix any errors

Definition of Done

This issue is complete when:

All subtasks above are completed and checked off.
A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly (fix(sandbox): remove type: ignore in SandboxManager strategy assignment), followed by a blank line, then additional lines providing relevant details about the implementation.
The commit is pushed to the remote on the branch fix/sandbox-manager-type-ignore.
The commit is submitted as a pull request to master, reviewed, and merged before this issue is marked done.
All nox stages pass.
Coverage >= 97%.

Transition Forgejo issue #2828 in cleveragents/cleveragents-core to State/In Progress.

Preconditions:

Current state: State/Verified
Target state: State/In Progress
Paused/Blocked status: Not paused; Blocked label not present. No blocker check needed.

Actions planned:

Remove old state label: State/Verified
Add new state label: State/In Progress
Do not modify other labels (Priority, MoSCoW, Type, etc.)
Do not close the issue (not Completed)

Notes:

The issue currently has labels: MoSCoW/Should have, Priority/Medium, State/Verified, Type/Bug.
Blocked label is not present, so no blocker linkage required.

If you would like me to proceed with applying the label changes automatically via Forgejo’s label API, please confirm. Otherwise, I’ve prepared this update and will apply the changes once I have the necessary permissions or an available API endpoint to modify labels.

Starting implementation on branch fix/sandbox-manager-type-ignore.

Difficulty assessment: Low complexity (single-line type-safe cast fix) → starting at sonnet tier.

The fix involves:

Locating the # type: ignore[assignment] at manager.py line 618
Implementing a type-safe conversion from SandboxStrategy to SandboxStrategyStr
Writing a Behave test scenario to cover the conversion path
Running all nox quality gates

Label compliance fix applied:

Added missing label: Type/Bug — inferred from issue title/body (type-safety violation with # type: ignore)
Added missing label: Priority/Medium — inferred from issue context (coding standards violation, no runtime impact)
Added missing label: MoSCoW/Should have — inferred from issue context
Reason: Per CONTRIBUTING.md, every issue must have exactly one State/*, one Type/*, and one Priority/* label.
