How do the Call-back (rest) provisions of two dated Studio Local agreements (2015 Local 871, 2021 Local 728) differ in rest hours and weekend rest?

The 2015 Local 871 text sets 8/9/10-hour post-dismissal rests and contains no weekend-rest provision (curator search: 0 matches), while the 2021 Local 728 text sets a 10-hour daily rest plus 54/32-hour weekend rests; both carry the same 6-hour first-meal and 12-minute grace wording. Curator qualifications: Whether the difference reflects negotiated change over time or local difference is not established (producer synthesis correctly declines a chronology). Absence of weekend provision is a text-extraction search result; OCR/extraction gaps possible. No legal or employment advice; applicability to a given production or job not determined; later MOAs/agreements not read. PDF text extraction only. Limitations: PDF text extraction only. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
