The dev directory now holds source code + compiled binaries only:
~/trips/osm/ OSM PBF extracts (was osm/, 1.4 GB)
~/trips/tilecache/ mock tile cache (was mock/.tilecache)
~/trips/store/mock/ per-trip uploads + chat logs (was mock/store, PII)
~/trips/logs/ server.log
~/trips/stale-osm-build/ stale source/tarball dup of ~/osm-build
(repo osm/build had no binaries; the live OSRM
toolchain + graphs already lived in ~/osm-build)
Code now points at the new locations, all overridable via env:
- mock/server.js: TRIPS_HOME (default ~/trips) for tile cache + store
- setup-osrm.sh / setup-osrm-colombia.sh: OSM_DIR (default ~/trips/osm)
- spatial/compose+import.sh: OSM_DIR (default ~/trips/osm)
- .gitignore: rewritten — no artifact paths remain in-tree
