+# Format (one rule per line, prefix-tagged):
+#   PATH <repo-relative path or directory>
+#       Fails if the file or directory exists.
+#       strip-fee.sh removes it via `git rm -rf`.
+#   SYMBOL <ERE regex>
+#       Fails if the regex matches in any tracked .rs file under program/src/.
+#       strip-fee.sh DOES NOT auto-edit source — the user must hand-resolve.
+#
+# Lines starting with `#` and blank lines are ignored.
+#
+# Why this file exists:
+#   program-v2 is the "no-profit" foundation clone of lazorkit-protocol.
+#   When cherry-picking feature commits from lazorkit-protocol, the fee/admin
+#   paths must be excluded. This file is the single source of truth for what
+#   counts as "fee surface".

+# Post-cherry-pick cleanup: remove fee/admin surface that may have been

+# Workflow:
+#   1. Apply the upstream patch:    git am --3way path/to/feature.mbox
+#                              or:  git apply path/to/feature.patch && git add -A

+#   3. Hand-resolve any remaining symbol leaks reported below.
+#   4. Verify:                      ./scripts/check-no-fee.sh
+#   5. Commit the cleaned result.
+#
+# Behavior:
+#   - PATH rules are auto-removed via `git rm -rf` (when present).
+#   - SYMBOL rules are NOT auto-edited — stripping a struct/function reference
+#     from the middle of a file requires understanding context. The script
+#     prints each offending file:line and exits non-zero so the user notices.
+#
+# Use --dry-run to see what would happen without modifying anything.
