v0.3.0

Added

• storage_capacity_rca reports a domain the engine cannot warn about. The engine returns 0
  for a threshold that is not set, and 0 can never be crossed, so a domain with
  warning_low_space_indicator: 0 produced no space finding at whatever free space — silence
  that reads as "nothing to report". It is now a low finding carrying the measured free
  space, in two forms: no threshold at all, or only the critical blocker (where the engine
  already refuses new disks, so there is no earlier signal). It does not invent a threshold of
  its own: how full is too full is the operator's policy and is not recorded on the domain.

Fixed

• The over-commit severity is derived from the measured thresholds instead of from scanning
  the other findings' text — a finding that merely names the critical blocker (the new one
  does) was read as "the domain is low on space".
