# Bump Service Configuration
#
# Every BUMP_* variable below is optional and mirrors a default already
# defined in src/config.rs. Config loading now tolerates partial env (each
# field falls back to its own code default when unset), so you only need to
# set the ones you actually want to override — the values below match the
# built-in defaults and are provided as a reference / starting point.

# Matching parameters
BUMP_MAX_DISTANCE_METERS=250       # meters
BUMP_MAX_TIME_DIFF_MS=1500         # milliseconds (server-assigned timestamps need this headroom)
BUMP_DEFAULT_TTL_MS=500            # milliseconds

# Scoring weights (must sum to 1.0)
BUMP_TEMPORAL_WEIGHT=0.7
BUMP_SPATIAL_WEIGHT=0.3
