Module: StillActive::CeilingReconciler

Extended by:
CeilingReconciler
Included in:
CeilingReconciler
Defined in:
lib/still_active/ceiling_reconciler.rb

Overview

Whole-tree correlation between the two capping signals, run once after the fan-out (native or SBOM) has assembled every package's findings. A language ceiling that says "upgrade to lift it" is wrong if the same tree poisons below that upgrade (a dormant dependency caps it): the report must never advise an upgrade its own poison finding says is impossible. All data is already in the assembled result, so this is one pass, no fetches. "The correlation layer must correlate."

def reconcile_ceiling_with_poison(result_object)
  # Qualify each capped dependency by the ecosystem that declares the cap. A
  # capped dep resolves in its parent's ecosystem, so a poison finding on a
  # `pypi` package caps a `pypi` dependency. A mixed SBOM has two flat-
  # resolution ecosystems (rubygems + pypi), so a bare-name match alone would
  # let a rubygems poison-cap on "foo" wrongly block a pypi "foo"'s ceiling.
  # Native results carry no :ecosystem (all rubygems) -> nil on both sides,
  # still consistent.
  capped = result_object.each_value
