I am not sure yet either …
Searching for “senāsanagāhāpaka” in the Ajahn Brahmali’s (not yet published, but publicly visible on GitHub) Vinaya translation, I get no result.
Searching for “senāsanapaññāpaka” I find a few results:
- In Bhikkhu Sanghadisesa 8, Venerable Dabba the Mallian is appointed as assigner of dwellings and designator of meals (senāsanapaññāpakassa ca bhattuddesakassa ca).
- In several Pacittiya rules there is a list of monastic jobs that always includes the lodgings assigner (senāsanapaññāpaka), but never the lodgings allocator (senāsanagāhāpaka).
senāsanapaññāpakaṁ vā bhattuddesakaṁ vā yāgubhājakaṁ vā phalabhājakaṁ vā khajjabhājakaṁ vā appamattakavissajjakaṁ vā
Searching through all the Khandhakas individually, I find in Kd 16 a chapter on appointing an allocator of dwellings, senāsanaggāhāpaka. (Note that unlike in AN 5.273-285, it is here spelled with double g, which makes it difficult for search to find it.)
Reading the explanation of the senāsanaggāhāpaka’s job, it just says he has to allocate dwellings, one bed for each monk, or one dwelling for
each monk, or each monk gets their own dwellings precincts, depending on the number of monastics present.
In the same Khandhaka we also find the senāsanapaññāpaka. He occurs again together with the other jobs, as in the Pc rules. Unfortunately, due to abbreviation, only the last job in the list receives a description, and so we don’t learn from this text what exactly the dwellings assigner has to do.
So we are left with the very useful information that the dwellings assigner is assigning dwellings, and the dwellings allocator is allocating them …
I’d be thankful for further input by Ajahns @sujato and/or @brahmali.
