FA-42546 / Listener lifecycle / Open access

A new outer notification reuses the previous inner generation · case 01

A new outer notification reuses the previous inner generation; the returned lifecycle plan violates the stated transition contract.

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

ROOT CAUSE

The generation decision in the switch-inner listener model is computed as s['generation'], losing a required lifecycle condition.

VERIFIED REPAIR

Compute the generation decision from the complete contract: s['generation']+int(s['outer_value']).

Unsuccessful approach: The partial repair uses s['generation']+1; a retained regression distinguishes it from the full transition.

Case contract

Plan switch-to-latest observer ownership. A new outer value replaces the active inner and advances an inner generation. Late values from the replaced generation are suppressed. Outer completion waits for the current inner, while an inner completion alone does not close a live outer. An error closes both. Dispose the old inner before starting the replacement, even if it emitted no value. Completion considers only active inner records belonging to the current generation; stale active records and current inactive records do not block it. 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: replace = s['outer_value'] and s['inner_active']; generation = s['generation']+int(s['outer_value']); accept = s['event_generation']==s['generation'] and s['inner_active'] and not s['cancel'] and s['error'] is None; outer_complete = s['outer_done'] and not any(active for generation,active in s['inner_records'] if generation==s['generation']); inner_complete = s['inner_done'] and s['outer_done']; start = s['outer_value'] and not s['outer_done'] and not s['cancel'] and s['error'] is None; transition_order = ['dispose','start'] if s['outer_value'] and s['inner_active'] else (['start'] if s['outer_value'] else []); active_after_done = s['inner_active'] and not(s['inner_done'] and s['event_generation']==s['generation']); dispose_outer = s['error'] is not None or s['cancel']; late_value = s['event_generation']!=s['generation']

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.
