# 0005 — Structured-first; semantic search over the vault deferred

## Context

Tag filtering ("client/sesame3g + tool/semrush") may miss notes whose wording
  doesn't match the query ("how do we use semrush" vs a note titled "search analytics
  integration").

## Decision

Ship the knowledge layer **structured-only** (tags + summaries). **Defer**
  meaning-based search over the vault until it demonstrably bites.
- **Rationale**: Structured tagging is the lightweight/fast thing the user wants, and the
  summary+tag design is built to make it work. Follow the video's "only level up when it bites."

## Consequences

The knowledge layer shipped structured-only (tags + summaries), deliberately deferring meaning-based/semantic search over the vault until it demonstrably became necessary. This premise was later superseded by ADR-010, since Graphify provides structured and connection-based recall together from day one rather than requiring a separate semantic layer to be bolted on later.

## Alternatives rejected

None stated in source.
