 Goal:
 
-- Merge independent extraction results into a coherent meeting-level
-  representation without losing evidence.
+- Convert independent chunk extraction JSON into a validated, normalized,
+  evidence-bearing intermediate representation without semantic guessing.
 
 Deliverables:
 
-- Duplicate merging.
-- Evidence retention.
-- Category-shift reconciliation, especially facts versus positions and
-  positions versus decisions.
-- Contradiction and uncertainty markers.
-- Consolidated meeting representation.
+- Deterministic Canonicalizer implemented in Python.
+- Stable source references and IDs.
+- Normalized category names and basic field structure.
+- Safe deterministic cleanup.
+- Exact duplicate grouping where unambiguous.
+- Preservation of all source evidence.
 
 Prerequisites:
 
 - Stable local extraction baseline.
-- Gold tests that expose cross-chunk duplication and category shifts.
+- Agreement on the extraction object shape that should be canonicalized.
