# Invoke-CurabisEvidence.ps1
#
# Validerer at hver citation i en gemt review/audit/triage-rapport peger paa noget
# der FAKTISK findes - hegnet mod hallucinerede henvisninger (jf. CURABIS-TRIAGE-005
# "cite or flag" og ALDC's validate_evidence.py).
#
# Tjekker to slags citationer:
#   1. Knowledge-filer  - BCQuality-URL'er eller relative stier (custom/.., microsoft/..)
#                         -> skal resolve mod en lokal BCQuality-klon eller via HTTP.
#   2. CURABIS-regelkoder - CURABIS-ARCH/TRIAGE/COMPLEXITY-NNN
#                         -> skal vaere defineret i .github\.agents\*.agent.md.
# (AL-diagnostikkoder som AS0084/AA0218 er Microsofts og valideres ikke her.)
#
# Exit 1 hvis en eneste citation ikke kan resolves (egnet til CI / PR-gate).
#
# Brug:
#   pwsh -File scripts\Invoke-CurabisEvidence.ps1 -ReportPath review.md
#   "AL Triage cited CURABIS-ARCH-002" | pwsh -File scripts\Invoke-CurabisEvidence.ps1
