Dismissal veto leaves a menu attached to a removed owner · case 01

Dismissal veto leaves a menu attached to a removed owner.

Verified by executionVariant 1 · 7 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

The menu-dismissal-policy model applies `not p['vetoed']` at its mandatory-teardown operation instead of the stipulated transformation.

THE FAILURE

The menu-dismissal-policy model applies `not p['vetoed']` at its mandatory-teardown operation instead of the stipulated transformation.

Unsuccessful approach: The attempted repair `p['owner_removed'] and not p['vetoed']` still violates the mandatory-teardown oracle.

Case contract

Menu dismissal reasons map to explicit close scopes; command completion, owner removal and outside dismissal do not share a universal policy.

Why this case matters

Cascading and context menus require coherent command and session state as content changes.

HELD IN THE MEMBER ARCHIVE

The verified repair and its recorded checks are member-only.

This mechanism has 7 recorded checks per implementation. The open-access tier publishes the failure and the unsuccessful fix; the repaired source that passes every check, and the observations that prove it, are available to members.

Every case sharing this mechanism uses the same contract and the same repair, so this one record is held back for all of them.

Member access is invitation-based. Sign in with your invited account to inspect the repair.

Verification & scope

Offline supplied-valid-payload model; excludes DOM, keyboard, focus, selection, announcements and browser conformance. 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.
