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.
