 The report must be self-contained — someone reading it later should understand the full discussion, including the reasoning and all relevant details, without having been there. Err on the side of including too much detail rather than too little.
 
-Include a link to the companion transcript where it fits naturally — an Obsidian wikilink like `[[{{title}}_transcript]]` in the section where it makes the most sense (often near the end).

+## Frontmatter
+
+Both the report and the transcript use the merged OKF + vault frontmatter schema:
+
+```yaml
+---
+type: Conversation Report         # report: Conversation Report, transcript: Conversation Transcript
+title: <descriptive title>
+description: <one-line summary>
+tags: [conversation, <topic>]
+timestamp: <ISO 8601 datetime>
+id: <unique-slug>
+aliases: []
+area: <derived from conversation>
+project: ''

+
+## Bundle Awareness
+
+`AI Conversation Summaries/` is an OKF bundle. After writing each new report/transcript pair:
+
+1. Update `AI Conversation Summaries/index.md` — add an entry for the new report and transcript.
+2. Append an entry to `AI Conversation Summaries/log.md` noting the addition.
