pdfalto 0.6.1 streams large page DOMs to a scratch file to bound peak memory, and reports new exit codes for it. Two consequences here: - Exit code 5 means the ALTO was written correctly but streaming was disabled mid-run, so peak memory was not bounded. Both execution paths rejected any non-zero exit, so these successful conversions would have been thrown away as PDFALTO_CONVERSION_FAILURE - on exactly the large documents streaming exists to rescue. It is now a logged warning. Codes 4 (write failed) and 98 (allocation failure, previously a SIGABRT) are reported as PDFALTO_CONVERSION_FAILURE rather than falling through to BAD_INPUT_DATA, which blamed the input PDF. - pdfalto picks the scratch file location from $TMPDIR and falls back to /tmp. In a container /tmp is tmpfs, so spilling there leaves peak memory unchanged and risks ENOSPC, defeating the streaming. Both launchers used a bare ProcessBuilder and never set it. They now pass GROBID's configured temp directory (grobid.temp, by default grobid-home/tmp), failing soft back to pdfalto's default. The pdfalto command-line options are unchanged: the new -vectorBoxes, -vectorCoordsOnly and -vectorLimit options all concern vector graphics, which GROBID does not use.
