# test_card_drift_probe.sh — session_close_check.sh ⑤-b 카드-드리프트 프로브의 known-pair 픽스처.
#
# WHY: 프로브 자체가 계기다 — CLAUDE.md §Instrument Calibration 이 요구하는 known-pair
# (양성 1 + 음성 1)를 통과하지 못하는 프로브는 배선하면 안 된다(다음 오판정의 원천이 된다).
# 이 파일이 그 캘리브레이션의 회귀 앵커: 프로브 정규식/토큰추출을 고칠 때마다 재실행.
#
# 픽스처 3종:
#   P  (known-positive): 카드가 🔴 "foo-digest 미가동 — 산출물 0" 주장 + 실물
#                        tracks/_meta/foo_digest_2026_07_22.md 존재 → ⑤-b 경고가 떠야 한다
#   N1 (known-negative): 카드가 부재 주장하는 bar-report 는 진짜 없음 → 경고 0
#   N2 (과발화 가드):    같은 실물이 있어도 부재-주장이 아닌 🟢 줄 → 경고 0
#                        (건강한 날 뜨는 경고는 무시를 학습시킨다 — 과발화도 결함)
#
# Exit 0 = 3/3 캘리브레이션 통과 · exit 1 = 프로브 계기 불량 (배선 금지)

# 🟥 ENVIRONMENT ISOLATION (2026-08-27). `CLAUDE.local.md` INSTRUCTS this operator to export
# FH_COMPANION_STORE, so the suite inherited a REAL companion store and ⑤-C compared each FIXTURE
# card against the operator's actual prior card — reporting a carry-over loss that belongs to
# neither. Measured A/B on this file: exported → rc 1 with 6 exit-code lanes red · unset → rc 0.
# The verdict CONTENT was right every time (every `_line` assertion passed); only the exit code
# moved, which is what made it read like an over-blocking script rather than an ambient leak.
# 🟥 THIS IS THE SECOND FILE WITH THIS LEAK. The sibling test_session_close_lanes.sh was fixed
# earlier the same day and this one was not — a half-fix propagation boundary created by the same
# author who had just named that class. Fixed together now; the sweep that found it is
#   grep -l session_close_check scripts/test_*.sh   → check each for an FH_COMPANION_STORE guard.
# Lanes that genuinely exercise ⑤-C set their own fixture store ON the invocation and still win.
# 🟥 CLASS, NOT INSTANCE. The first draft of this guard unset FH_COMPANION_STORE alone — the one
# variable that had actually bitten. That is the same shape as the half-fix that put this guard in
# only ONE of two sibling lane files hours earlier. Every operator-settable override the subject
# reads is the same window, so all of them are closed here rather than one at a time:
#   FH_COMPANION_STORE  ⑤-C reads a REAL prior card and reports a carry-over loss on a fixture
#   FH_SESSION_CLOSE    flips advisory into blocking — every `expect exit 0` lane would go red
#   FH_CARRYOVER_OK     SKIPs ⑤-C — a lane asserting ⑤-C FIRES would go green for the wrong reason
#                       (note the direction: this one fails OPEN, which is the worse half)
#   FH_PEER_SCAN_FORCE  forces the ①-c peer scan on regardless of session shape
#   FH_PEER_SOCK_DIR / FH_REPO_ID   repoint peer discovery at the ambient machine
# CLAUDE_CODE_AGENT / CLAUDE_CODE_CHILD_SESSION are deliberately NOT in this list: the subject uses
# them to detect session shape and the lanes that care unset them per-case on purpose (see the
# subject's own "NEGATIVE ARM UNVERIFIED" note). Blanket-clearing them here would silently change
# which branch those lanes exercise.

  # indistinguishable from "no match", so the probe reported the card clean on every input.

# The behavioural dual-run above cannot fire on BSD grep, so the class needs a detector that does
# not depend on which grep is installed. This one reads the SOURCE: a bracket expression containing
# a non-ASCII RANGE (`[^가-힣]`, `[ㄱ-ㅎ]`, …) is collation-dependent by construction and will be
# rejected outright by GNU grep in the C locale — "Invalid collation character", exit 2, no output,
# which downstream reads as "no match" and therefore as clean.
# Alternation of non-ASCII literals (`(🔴|🟡)`, `미가동|부재`) is NOT flagged: it carries no
# collation, and the runner proved it works (the emoji line-selection stage passed there while the
# range stage errored). Flagging it would push an author to mangle working code.
