Scope exit claims ownership of borrowed listeners · case 01

Scope exit claims ownership of borrowed listeners; the returned lifecycle plan violates the stated transition contract.

Verified by executionVariant 1 · 8 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The borrowed decision in the scope-exit listener model is computed as [], losing a required lifecycle condition.

VERIFIED REPAIR

Compute the borrowed decision from the complete contract: [x for x in s['children'] if x in s['borrowed']].

Unsuccessful approach: The partial repair uses s['borrowed']; a retained regression distinguishes it from the full transition.

Case contract

Plan closing an observer ownership scope. Owned children close in reverse acquisition order, borrowed children remain alive. Every cleanup executes even if prior cleanup failed; aggregate the errors. Closed scopes reject adoption, preserve their terminal marker and release their parent link exactly once. Ownership edges are [parent,child]; detaching a scope removes edges targeting that scope, not siblings from the same parent. Scope lifecycle is monotonic open < closing < closed; delayed requests cannot regress it and closing is not already closed. Inputs are finite state snapshots, including transitional and stale states; output fields are the exact independent actions/metadata defined by the corrected expression table. Numeric fixture capacities and counts vary with N. Field definitions, each independently computed from the input snapshot: order = list(reversed([x for x in s['children'] if x not in s['borrowed']])); borrowed = [x for x in s['children'] if x in s['borrowed']]; errors = list(s['errors']); adoption = s['adopt'] and not s['closed'] and not s['closing']; parent_release = [r for r in s['ownership_edges'] if r[1]!=s['scope_id']]; closed = max((s['phase'],s['requested_phase']),key=['open','closing','closed'].index); pending = 0 if s['closing'] or s['closed'] else s['pending']; remaining = len([x for x in s['children'] if x not in s['borrowed']]); continue = len(s['children']); parent_refs = max(0,s['refs']-int(s['parent'] and not s['already_released']))

Why this case matters

Observer implementations need to preserve this state while subscriptions enter, execute, and leave their lifecycle.

Verification & scope

A deterministic, bounded, single-threaded transition planner. Returned plans model state changes; they do not implement a production event framework. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
