Summary

Removes a # type: ignore[assignment] comment from SandboxManager.get_or_create_sandbox_for_resource that violated the project's strict no-type-suppression coding standards, replacing it with a semantically correct and statically verifiable cast() call from the typing module.

Changes

• Removed # type: ignore[assignment] from manager.py line 618: The suppression comment was masking a type mismatch between SandboxStrategy (a StrEnum) and SandboxStrategyStr (a Literal[...] type alias). While the two types are structurally compatible at runtime, Pyright could not verify this statically, leading to the suppression. The comment has been fully removed.

• Added from typing import cast import to manager.py: The cast function from the standard library typing module is now imported to enable the type-safe assignment.

• Replaced suppressed assignment with cast("SandboxStrategyStr", boundary_resource.sandbox_strategy): The previously suppressed line:

  strategy = boundary_resource.sandbox_strategy  # type: ignore[assignment]
  

  is now:

  strategy = cast("SandboxStrategyStr", boundary_resource.sandbox_strategy)
  

  This is semantically correct because SandboxStrategy (StrEnum) and SandboxStrategyStr (Literal) share exactly the same string value set, making the cast safe at both the type-checker and runtime levels.

• Added features/sandbox_manager_strategy_cast.feature: A new Behave feature file with 2 scenarios that exercise the get_or_create_sandbox_for_resource method with a non-None sandbox_strategy, ensuring the cast conversion path is covered by the test suite.

• Added features/steps/sandbox_manager_strategy_cast_steps.py: Step definitions for the new feature file, following the established mocking pattern from sandbox_manager_coverage_r3_steps.py to avoid DAG traversal by mocking the boundary cache.

Design Decisions

• cast() over SandboxStrategyStr(...) constructor call: SandboxStrategyStr is a Literal type alias, not a callable class. Attempting to call it as a constructor would raise a TypeError at runtime. cast() is the correct tool here — it is a no-op at runtime (returns its second argument unchanged) and serves purely as a static type annotation hint for Pyright.

• String form "SandboxStrategyStr" in the cast() call: The file uses from __future__ import annotations, which defers evaluation of all annotations. Using the string form "SandboxStrategyStr" in the cast() call ensures consistency with the file's annotation style and avoids any forward-reference issues.

• No dedicated conversion/validation helper function: The issue suggested a possible helper function to map SandboxStrategy → SandboxStrategyStr. This was evaluated and rejected for this fix: the two types are guaranteed by design to share the same string values (they represent the same domain concept), so a runtime validation step would add complexity without safety benefit. A cast() is the idiomatic, minimal, and correct solution.

• Boundary cache mocking in tests: The new Behave step definitions mock the boundary cache to avoid triggering DAG traversal, following the established pattern in sandbox_manager_coverage_r3_steps.py. This keeps the tests fast, isolated, and focused on the specific code path under test.

Testing

• Unit tests (Behave): ✅ 2/2 new scenarios passed; 63/63 sandbox manager coverage scenarios passed
• Integration tests (Robot): Not applicable — this is a type-safety fix with no behavioural change
• Type checking (nox -e typecheck): ✅ 0 errors, 0 warnings
• Coverage: ≥ 97% (no regression)
• Benchmarks: Not needed — no performance-sensitive code paths modified

Modules Affected

• src/cleveragents/infrastructure/sandbox/manager.py — removed # type: ignore[assignment], added cast import, replaced suppressed assignment with cast() call
• features/sandbox_manager_strategy_cast.feature — new Behave feature file (2 scenarios)
• features/steps/sandbox_manager_strategy_cast_steps.py — new Behave step definitions

Related Issues

Closes #2828

Checklist

• All nox stages pass (lint, typecheck, unit_tests, integration_tests, coverage_report)
• Coverage >= 97%
• No # type: ignore directives
• Commit message follows Conventional Changelog format
• Implementation aligns with docs/specification.md

## Summary Removes a `# type: ignore[assignment]` comment from `SandboxManager.get_or_create_sandbox_for_resource` that violated the project's strict no-type-suppression coding standards, replacing it with a semantically correct and statically verifiable `cast()` call from the `typing` module. ## Changes - **Removed `# type: ignore[assignment]` from `manager.py` line 618**: The suppression comment was masking a type mismatch between `SandboxStrategy` (a `StrEnum`) and `SandboxStrategyStr` (a `Literal[...]` type alias). While the two types are structurally compatible at runtime, Pyright could not verify this statically, leading to the suppression. The comment has been fully removed. - **Added `from typing import cast` import to `manager.py`**: The `cast` function from the standard library `typing` module is now imported to enable the type-safe assignment. - **Replaced suppressed assignment with `cast("SandboxStrategyStr", boundary_resource.sandbox_strategy)`**: The previously suppressed line: ```python strategy = boundary_resource.sandbox_strategy # type: ignore[assignment] ``` is now: ```python strategy = cast("SandboxStrategyStr", boundary_resource.sandbox_strategy) ``` This is semantically correct because `SandboxStrategy` (StrEnum) and `SandboxStrategyStr` (Literal) share exactly the same string value set, making the cast safe at both the type-checker and runtime levels. - **Added `features/sandbox_manager_strategy_cast.feature`**: A new Behave feature file with 2 scenarios that exercise the `get_or_create_sandbox_for_resource` method with a non-`None` `sandbox_strategy`, ensuring the cast conversion path is covered by the test suite. - **Added `features/steps/sandbox_manager_strategy_cast_steps.py`**: Step definitions for the new feature file, following the established mocking pattern from `sandbox_manager_coverage_r3_steps.py` to avoid DAG traversal by mocking the boundary cache. ## Design Decisions - **`cast()` over `SandboxStrategyStr(...)` constructor call**: `SandboxStrategyStr` is a `Literal` type alias, not a callable class.

fix(sandbox): remove type: ignore in SandboxManager strategy assignment ... 68a3cc40ca

Implemented removal of the type: ignore in SandboxManager strategy assignment by introducing a proper typing.cast usage and added tests to cover the new path.

- What was implemented
  - Added from typing import cast to src/cleveragents/infrastructure/sandbox/manager.py.
  - Replaced strategy = boundary_resource.sandbox_strategy  # type: ignore[assignment] with strategy = cast("SandboxStrategyStr", boundary_resource.sandbox_strategy) at line 618 in get_or_create_sandbox_for_resource.
  - The cast is semantically correct: SandboxStrategy (StrEnum) values are exactly the same string set as SandboxStrategyStr (Literal), so the cast is a truthful type assertion with zero runtime overhead.
  - Added features/sandbox_manager_strategy_cast.feature with 2 Behave scenarios exercising the cast conversion path.
  - Added features/steps/sandbox_manager_strategy_cast_steps.py with step definitions.

- Key design decisions
  - Used cast() from typing rather than SandboxStrategyStr(...) constructor call, because SandboxStrategyStr is a Literal type alias (not a callable), so calling it as a constructor would fail at runtime.
  - Used string form "SandboxStrategyStr" in the cast call because the file uses from __future__ import annotations.
  - Mocked the boundary cache in tests to avoid DAG traversal, following the pattern established in sandbox_manager_coverage_r3_steps.py.

- Affected modules/components
  - src/cleveragents/infrastructure/sandbox/manager.py
  - features/sandbox_manager_strategy_cast.feature
  - features/steps/sandbox_manager_strategy_cast_steps.py

- Testing considerations
  - The new Behave scenarios exercise the cast path in isolation, reducing DAG traversal concerns and aligning with existing testing patterns.

Review: APPROVED ✅

(Posted as COMMENT because the Forgejo API token belongs to the PR author and self-approval is not permitted. The review assessment is APPROVE.)

Summary

This PR correctly removes a # type: ignore[assignment] suppression from SandboxManager.get_or_create_sandbox_for_resource and replaces it with an idiomatic typing.cast() call. The change is minimal, correct, and well-tested.

Review Findings

Specification Alignment ✅

• The sandbox module's runtime behavior is unchanged — cast() is a no-op at runtime.
• The fix aligns with CONTRIBUTING.md's strict no-type-suppression policy.

Correctness ✅

• Type safety verified: SandboxStrategy (StrEnum) has exactly the same 6 string values (git_worktree, copy_on_write, transaction_rollback, snapshot, overlay, none) as SandboxStrategyStr (Literal). The cast is truthful.
• cast() over constructor: Correct decision — SandboxStrategyStr is a Literal type alias, not callable. Attempting SandboxStrategyStr(...) would raise TypeError at runtime.
• String form "SandboxStrategyStr": Correct — the file uses from __future__ import annotations, so string-form is consistent.

Code Quality ✅

• Import placed correctly at top of file alongside other standard library imports.
• Single-line change in production code — minimal blast radius.
• manager.py is 655 lines (exceeds 500-line guideline), but this is pre-existing and not introduced by this PR.

Test Quality ✅

• Two Behave scenarios exercise the cast() path via get_or_create_sandbox_for_resource with a non-None sandbox_strategy.
• Step definitions follow the established boundary-cache mocking pattern from sandbox_manager_coverage_r3_steps.py.
• Minor note: both scenarios use SandboxStrategy.NONE — testing with a second strategy value (e.g., GIT_WORKTREE) would add diversity, but since cast() is a no-op regardless of value, this is not a blocking concern.

Security ✅

• No secrets, credentials, or injection risks.

CI Status ✅

All required checks passing: lint, typecheck, security, quality, unit_tests, integration_tests, e2e_tests, coverage, build, status-check.

Commit Message ✅

• Follows Conventional Changelog format: fix(sandbox): remove type: ignore in SandboxManager strategy assignment
• Includes ISSUES CLOSED: #2828 footer.

Metadata Fix Applied

• Assigned milestone v3.7.0 to match the linked issue.

Independent Review: APPROVED ✅

(Posted as COMMENT because the Forgejo API token belongs to the PR author and self-approval is not permitted. The independent review assessment is APPROVE.)

Independent Review Summary

Thorough review of all 3 changed files against the specification, CONTRIBUTING.md, and codebase conventions. This is a second, independent review providing a different perspective from the initial self-review.

Specification Alignment ✅

• The sandbox module's runtime behavior is completely unchanged — cast() is a no-op at runtime.
• The fix directly addresses the CONTRIBUTING.md strict no-type-suppression policy: "The use of # type: ignore or any other mechanism to suppress type-checking errors is strictly forbidden."
• Module boundaries respected — the change is confined to the sandbox infrastructure layer.

Correctness ✅

• Type safety verified: SandboxStrategy (StrEnum) has exactly the same 6 string values (git_worktree, copy_on_write, transaction_rollback, snapshot, overlay, none) as SandboxStrategyStr (Literal). The cast is truthful.
• cast() is the correct tool: SandboxStrategyStr is a Literal type alias, not a callable class. Attempting SandboxStrategyStr(...) would raise TypeError at runtime. The issue's suggestion of a constructor call was correctly evaluated and rejected.
• String form "SandboxStrategyStr": Correct — the file uses from __future__ import annotations, so string-form is consistent.
• Established pattern: cast(SandboxStrategyStr, ...) is already used in _base.py (lines 132, 306) and resource_handler_service.py (line 394). This PR follows the existing codebase convention.

Code Quality ✅

• Import from typing import cast placed correctly at top of file alongside other standard library imports.
• Single-line change in production code — minimal blast radius.
• No unnecessary complexity introduced.

Test Quality ✅

• Two Behave scenarios exercise the cast() path via get_or_create_sandbox_for_resource with a non-None sandbox_strategy.
• Step definitions follow the established boundary-cache mocking pattern from sandbox_manager_coverage_r3_steps.py.
• _STRATEGY_MAP includes all 6 strategies for future test expansion.
• Minor observation: both scenarios use SandboxStrategy.NONE — testing with a second strategy value (e.g., GIT_WORKTREE) would add diversity, but since cast() is a no-op regardless of value, this is not a blocking concern.

Security ✅

• No secrets, credentials, or injection risks.

Commit Message ✅

Code Review — LGTM ✅

PR: fix(sandbox): remove type: ignore in SandboxManager strategy assignment

Review Checklist

✅ Correctness: Replaces # type: ignore[assignment] with a semantically correct cast() call. This is the correct approach — cast() is a type-safe way to assert a type without suppressing the checker.

✅ Type Safety: Removes a type suppression violation. No # type: ignore directives remain. Pyright passes.

✅ Commit Format: fix(sandbox): follows Conventional Changelog format.

✅ Labels/Milestone: Priority/Medium, Type/Bug, milestone v3.7.0 — correctly assigned.

Decision: LGTM — Proceeding to merge when CI passes.

Labels

Clear labels

auto/needs-reevaluation

Controller deferred this PR; awaiting Phase 6+ scope-evaluator or operator re-enablement.

controller-managed

Auto-agents controller manages this PR/issue (see tools/controller/deploy/RUNBOOK.md). Remove this label to abandon controller management.

overdue

auto/blocked-by-deps

PR blocked by an open issue dependency. Operator must close the dep (or remove the dependency link) before the merge driver can act. Auto-cleared by merge_drive when no open deps remain.

auto/ci-timeout

Most recent merge cycle hit CI timeout. Driver excludes this PR while last merge_cycle row is < 30 min old; label persists thereafter as visible history.

auto/claimed-implementer

Currently being processed by an implementer worker.

auto/claimed-merge

Currently being processed by the merge driver.

auto/claimed-reviewer

Currently being processed by a reviewer worker.

auto/driver-down

Merge driver heartbeat stale; pipeline halted. Closed automatically on next clean tick.

auto/invariant-violation

Detected master commit violating the strict merge invariant. Tracked as an issue (not a PR label); kept here for label completeness.

auto/last-attempt-tier-0

In-cycle escalation: most recent attempt ran at the Tier 0 slot (`tier-0`). Slot's model defined in .opencode/models/tiers.yaml.

auto/last-attempt-tier-1

In-cycle escalation: most recent attempt ran at the Tier 1 slot (`tier-1`). Slot's model defined in .opencode/models/tiers.yaml.

auto/last-attempt-tier-2

In-cycle escalation: most recent attempt ran at the Tier 2 slot (`tier-2`). Slot's model defined in .opencode/models/tiers.yaml. Gated behind IMPLEMENTER_ESCALATION_TIER2_ENABLED.

auto/last-attempt-tier-min

In-cycle escalation: most recent attempt ran at the Tier -1 slot (`tier-min`). Slot's model defined in .opencode/models/tiers.yaml. Suffix is ``-min`` (not ``--1``) so the Forgejo UI reads naturally.

Automation Tracking

Tracking issues used by the AI Automation system for agents to communicate and report.

auto/needs-conflict-resolution

Rebase conflict needs LLM conflict-resolver.

auto/needs-implementer

Failing CI needs implementer attention.

auto/postmortem

Documenting a driver incident or rollback.

auto/ready-to-merge

Reviewer has APPROVED this PR and no later REQUEST_CHANGES is outstanding. The merge driver requires this label to even consider a PR for merging. Set by the reviewer worker on APPROVE; cleared on REQUEST_CHANGES.

auto/restart-throttled

Train repeatedly lost master-tempo races. Driver excludes via merge_cycle until cooldown elapses; label persists as visible history.

auto/revert

Revert PR backing out an invariant violation. Fast-tracked through the merge driver.

auto/sentinel

Sentinel PR duplicated from upstream into a personal fork by tools/duplicate_prs_to_fork.py for pipeline testing. Lives only in the fork; the canonical pipeline never sees it.

auto/stale-inactivity

No implementer activity for N days. Flagged for human review. Auto-cleared on next push to head branch.

auto/unstable

Repeatedly fails on current master (>= 3 ci-fail-on-rebased-sha releases in 12 h). Excluded from driver until human triage.

Blocked

A ticket in a blocked state and unable to complete until some other task is completed first.
