Preparing to merge this repository into a combined astrophotography
repo. session-scripts/ becomes pipeline/ because the scripts import
layout.py from their own directory and must stay together, and because
'pipeline' says what it is rather than how it came about. observing/
stays at the top level: observing plans are not processing code.
layout.path() treated every argument as a filename, so asking it for a
directory - layout.path('final'), which the rendering scripts do - built
a path to a file called 'final' INSIDE final/ and created an empty
final/final along the way. Directory names now resolve to the directory
itself.
Three scripts also held path literals split across two lines with
implicit string concatenation, where the rewrite had replaced only the
first fragment and left a dangling continuation. verify_core.py,
mo_gccheck.py and mo_mpc.py are corrected; all 52 files now compile
without warnings.
subdir_readmes.py writes a short README into each session subdirectory
saying what it holds, where it came from, and whether it is safe to
delete. Those three facts are what someone opening a folder cold needs,
and they belong with the data rather than in this repo.
Re-verified after the fix: closeup.py and triptych.py run end to end
against the reorganised session and leave no stray directories behind.
