Exchange governance v0.1.0 - Node Profile v0.2 Part II as executable UAPF

BPMN admission (AL0 -> AL2), four DMN decision tables and a CMMN case for
suspension, withdrawal and appeal.

The three rules that answer structural objections structurally:
- 17.2 circularity is a precondition, not a warning (avota-neatkariba). A
  participant cannot be the source of its own admission evidence, including
  where it commercially supplies company-register data.
- 15 adverse decisions fail closed: exhaustive grounds, 30-day notice, cure,
  5-working-day emergency review, two distinct officers, conflict-free appeal.
- 6.4 a legally significant answer is never T0.

Not an AI system (Reg. (EU) 2024/1689 Art. 3(1), Recital 12) - it does not
infer. It is the governance of one, and therefore in MIC sandbox scope.

resources/mappings.yaml traces every clause to its artefact and names the two
gaps the model cannot close alone.
