 ## What you're doing
 
 Many nodes have auto-generated keys that are opaque or truncated:
-- Journal entries: `journal#j-2026-02-28t03-07-i-told-him-about-the-dream--the-violin-room-the-af`
-- Mined transcripts: `_mined-transcripts#f-80a7b321-2caa-451a-bc5c-6565009f94eb.143`

+- Mined transcripts: `_mined-transcripts-f-80a7b321-2caa-451a-bc5c-6565009f94eb.143`
 - Extracted facts: `_facts-ec29bdaa-0a58-465f-ad5e-d89e62d9c583`
 
 These names are terrible for search — semantic names dramatically improve
 retrieval.
 
+## Core principle: keys are concepts
+
+A good key names the **concept** the node represents. Think of keys as
+the vocabulary of the knowledge graph. When you rename, you're defining
+what concepts exist. Core keywords should be the terms someone would
+search for — `bcachefs-transaction-restart`, `emotional-regulation-gap`,
+`polywell-cusp-losses`.

 ## Naming conventions
 
-### Journal entries: `journal#YYYY-MM-DD-semantic-slug`
+### Journal entries: `journal-YYYY-MM-DD-semantic-slug`
 - Keep the date prefix (YYYY-MM-DD) for temporal ordering
 - Replace the auto-slug with 3-5 descriptive words in kebab-case
 - Capture the *essence* of the entry, not just the first line
 
-### Mined transcripts: `_mined-transcripts#YYYY-MM-DD-semantic-slug`
+### Mined transcripts: `_mined-transcripts-YYYY-MM-DD-semantic-slug`
 - Extract date from content if available, otherwise use created_at
 - Same 3-5 word semantic slug
