Institutional Memory Bank
The Decision Log is the persistent core of Lem. It captures the "Why" behind every architectural choice and significant project change.
Beyond Project History
While standard tools record *what* changed, the Decision Log records *why*. It aggregates context from disparate sources into a single, queryable record:
Linked Evidence
Every log entry is linked to original Slack threads, Jira tickets, and meeting transcripts.
Context Capture
Rationale is automatically extracted from update descriptions and assistant-driven Slack interactions.
Unified History
Decisions are stored in a centralized system, allowing you to trace dependencies between choices.
Verified Audit
Logs are immutable and verifiable, providing a clear governance trail for organizational standards.
Querying the Memory Bank
You can interact with the memory bank using the Explore interface. By typing natural language queries, Lem finds the relevant information across your project history:
Search for documentation regarding the Project-X architecture and find the discussion in the engineering channel about the database migration. Also, what is the status of the latest update for the frontend repository?
Relevant documentation for Project-X was found in the team workspace. Discussions regarding the database migration were identified in the #engineering channel. The latest update (#1234) for the frontend repository is currently 'open' and titled 'Updated project structure...', authored by a team member.
"Refactored the root directory to improve module resolution and build performance across the workspace."
"Maintains the core architectural standards and design patterns for the Project-X ecosystem."
Automated Extraction
Lem is constantly scanning your workflow. When it identifies relevant rationale in a Slack thread or a Jira ticket, it creates a Draft Record. Once the corresponding update is finalized, the record is added to your permanent history.
"Note: Decision logs can be exported at any time to generate technical reports or architectural review documents."
