-#
-# oss-drift-check.sh — detect source drift between the canonical monorepo
-# substrate and the public OSS mirror (github.com/marolinik/hive-mind).
-#
-# WHY THIS EXISTS (§7.5 policy, ratified 2026-06-11):
-#   The monorepo is the SOLE source of truth for the memory substrate; the
-#   OSS mirror is generated FROM it. That invariant broke once: the
-#   cross-encoder reranker (inprocess-reranker.ts + HybridSearch options)
-#   was authored directly on the OSS repo during the LoCoMo benchmark arc
-#   and existed ONLY there — discovered by the W4 recon (2026-06-11),
-#   reverse-ported in W4.2 (f47ee8f). This script makes that class of
-#   drift cheap to detect BEFORE it compounds.
-#
-# WHAT IT DOES:
-#   Recursively diffs the substrate source trees (src/ only — dist, deps,
-#   lockfiles, and docs churn excluded) between the monorepo and a local
-#   checkout of the OSS repo. Reports per-file status:
-#     ONLY-IN-OSS   → candidate reverse-port (the W4.2 failure mode)
-#     ONLY-IN-MONO  → not yet exported (fine if a split is pending)
-#     DIFFERS       → divergent edits — inspect immediately
-#   Exit 0 = clean, exit 1 = drift found, exit 2 = setup error.
-#
-# USAGE:
-#   bash scripts/oss-drift-check.sh [path-to-oss-checkout]
-#   Default OSS path: ../hive-mind (sibling clone), override via arg or
-#   OSS_HIVE_MIND_DIR env var.
-#
-# WHEN TO RUN (maintainer ritual — manual, not CI):
-#   - before every OSS release push (alongside oss-subtree-split.sh)
-#   - after any benchmark/experiment arc that touched a hive-mind checkout
-#
-# Mapping (OSS repo keeps its own package layout):
-#   monorepo packages/hive-mind-core/src  ↔  oss packages/core/src
-#   (extend MAPPINGS below as more packages get mirrored surfaces)
