# test-sc4-phase9-coverage.sh — Verifies SC4 (Phase 9 critique-iterate coverage)
#
# Four checks:
#   (1) references/05-critique-iterate.md exists and carries the four
#       sub-phase headings '## 9a'..'## 9d'.
#   (2) SKILL.md carries the '## Phase 9 — Critique-iterate' section heading,
#       at least 5 'Phase 9' occurrences, and '### 9a'..'### 9d'.
#   (3) Every references/presets/*.md carries a critique-iterate hint block.
#       ANCHOR NOTE: the hint block's heading letter is PER FILE — four presets
#       end at '## (e)' and got '## (f) Critique-iterate hint'; four end at
#       '## (f)' and got '## (g) Critique-iterate hint'. The canonical
#       machine-checkable anchor is therefore the LETTER-FREE substring
#       'Critique-iterate hint'. Never anchor on the letter: a test grepping
#       '## (g)' would fail on four files, and the "fix" would be to break the
#       letter sequence in shipped content.
#   (4) references/05-critique-iterate.md carries >=1 Anthropic-domain citation.
#
# Anthropic-domain URL regex (same as test-sc3-citations.sh):
