What These Tests Verify

Covers all 4 public types in pdd/checkup_interactive_session.py:

ApprovedPatch coercions:

• str target is coerced to Path in __post_init__
• anchor dict is copied on construction (mutation independence)

seed() behaviour:

• Non-mapping report stores without raising
• Findings using finding_id key are imported correctly
• Pre-existing options are not overwritten (setdefault semantics)

present_finding() behaviour:

• Returns a new independent list each call (mutations do not affect subsequent calls)
• Returns empty list for unknown finding_id

ask() queue exhaustion:

• Returns "" when answers deque is empty

approved_patches() edge cases:

• Returns empty list when no choices recorded
• Two findings produce two ordered approved patches
• Re-presenting a finding allows a new valid record_choice() call
• no_patch kind is excluded from approved patches
• Returned patches are deep copies independent of internal state

Protocol conformance:

• FakeInteractiveSession satisfies the InteractiveRepairSession structural protocol
