+# ADR 0004: Store Original Transcript as Canonical Source
+
+## Status
+
+Accepted
+
+## Context
+
+Speech-to-text systems continuously improve over time. Likewise, AI-generated summaries, action items and other derived artifacts may evolve as better models become available.
+
+To ensure reproducibility, traceability and future reprocessing, the project requires a single immutable source of truth.
+
+## Decision
+
+The original transcript generated by the transcription engine is stored as the canonical transcript.
+
+The canonical transcript is immutable and must never be modified.
+
+A separate working transcript may be created for manual corrections such as:
+
+- spelling corrections
+- terminology normalization
+- speaker name assignment
+- punctuation improvements
+
+The working transcript shall maintain a reference to the canonical transcript from which it was created.
+
+All AI-generated artifacts (summaries, decisions, action items, knowledge objects, etc.) are derived from either the canonical transcript or a specific working transcript. The transcript version used must always be recorded.
+
+## Consequences
+
+- The original transcript remains permanently available.
+- Future AI models can regenerate improved summaries without requiring a new recording.
+- Manual corrections do not overwrite the canonical transcript.
+- Traceability and reproducibility are preserved throughout the system.
+- A working transcript enables manual improvements without compromising data integrity.
+- Every derived artifact can reference the transcript version from which it was generated.
+- Multiple working transcript revisions may coexist if required.
