- poller/docker-entrypoint.sh: convert from CRLF+BOM to LF (UTF-8 no BOM) Windows saved the file with a UTF-8 BOM which made the Linux kernel reject the shebang with 'exec format error', crashing the poller. - infrastructure/openbao/init.sh: same CRLF -> LF fix - poller/Dockerfile: add sed to strip CRLF and BOM at image build time as a defensive measure for future Windows edits - docker-compose.override.yml: add 'restart: on-failure' to api and poller so they recover from the postgres startup race (TimescaleDB restarts postgres after initdb, briefly causing connection refused on first boot) - .gitattributes: enforce LF for all text/script/code files so git normalises line endings on checkout and prevents this class of bug
