# test_marker_affected_lanes.sh — regression fixtures for pre-commit's
# validate_affected_leg (2026-09-04, frontier absorption of Anthropic AI-Native SDLC
# playbook intent.md's "Affected users and systems" / "Open questions" columns).
#
# WHY: FH does not split the two source columns into two marker fields — a second field is
# a second empty slot, the exact shape soul-check:/tenets:/thirdparty: already avoid. One
# free-prose line carries both, by convention ("건드리는 것 · 열린 질문 = …").
#
# SCOPE — channel, not judgment: single line · no duplicate · non-vacuous · not a bare
# placeholder. Unlike defeater:, "없음" is NOT a legal declared-absence here — every change
# touches something, so a placeholder-only value is an unfilled field, not an honest record
# of nothing. Absent (no `affected:` line at all) is legal — adoption is incremental, same
# shape as soul-check:/tenets:.
#
# Fixtures assert BOTH directions (known-pair): every intended shape is admitted, and every
# hole this lane closes still blocks.
#
# Usage: bash scripts/test_marker_affected_lanes.sh   Exit: 0 = all behave; 1 = regression.
