-- Galaxy Object Attributes/Tags for OPC UA Server
-- Returns all runtime-readable attributes for deployed automation objects.
-- Use full_tag_reference for read/write operations against the runtime.
-- Join with hierarchy.sql results on gobject_id to place attributes in the OPC UA browse tree.
--
-- Two sources of attributes:
--   1. attribute_definition (via primitive_instance) — system/primitive attributes
--      Joined via the instance's deployed_package_id to exclude undeployed changes.
--   2. dynamic_attribute — user-defined attributes (e.g., MachineID, MoveInFlag)
--      Walked via the deployed package derivation chain (package.derived_from_package_id)
--      to only include attributes that existed at deploy time.
--      When the same attribute appears at multiple levels (e.g., instance override and
--      base template), only the shallowest (most-derived) version is kept.
--
-- Historization detection: a dynamic attribute is historized when a primitive_instance
-- with a matching name exists in the deployed package chain and its primitive_definition
-- has primitive_name = 'HistoryExtension'.
--
-- Attribute category filter (mx_attribute_category):
--   2-11, 24 = runtime readable attributes
--
-- Attribute names starting with '_' are internal/hidden and excluded.
-- dynamic_attribute '.Description' suffixed entries are metadata, excluded.
--
-- Array dimensions are extracted from the mx_value hex string (bytes 5-6, little-endian
-- uint16 at hex positions 13-16). Works for both attribute_definition and dynamic_attribute.
--
-- Data types (mx_data_type):
--   1 = Boolean, 2 = Integer (Int32), 3 = Float (Single), 4 = Double,
--   5 = String, 6 = Time (DateTime), 7 = ElapsedTime (TimeSpan),
--   8 = (reference), 13 = (enumeration), 14 = (custom), 15 = InternationalizedString, 16 = (custom)
