+# allocate-address.sh — atomic creation-order address allocation for the vault.
+#
+# Reserves the next address of the form c-NNNNNN and increments the counter
+# under an exclusive flock. On missing counter file, recovers by scanning the
+# vault for the highest existing c-NNNNNN in page frontmatter and resuming from
+# max+1. Never silently resets to 1 in a non-empty vault.
+#
+# Usage:
+#   ./scripts/allocate-address.sh           # prints the reserved address (e.g. c-000042) to stdout
+#   ./scripts/allocate-address.sh --peek    # prints the next value without incrementing
+#   ./scripts/allocate-address.sh --rebuild # recomputes counter from max observed and exits
+#
+# Exit codes:
+#   0 — success
+#   1 — lock acquisition failed (another writer is holding the lock)
+#   2 — vault-meta directory missing and cannot be created
+#   3 — counter value corrupt or non-numeric
