 ## Project Overview
 
-Alexandria is a Nostr project written in Svelte 5 and SvelteKit 2.  It is a web app for reading, commenting on, and publishing books, blogs, and other long-form content stored on Nostr relays.  It revolves around breaking long AsciiDoc documents into Nostr events, with each event containing a paragraph or so of text from the document.  These individual content events are organized by index events into publications.  An index contains an ordered list of references to other index events or content events, forming a tree.
-
-### Reader Features
-
-In reader mode, Alexandria loads a document tree from a root publication index event.  The AsciiDoc text content of the various content events, along with headers specified by tags in the index events, is composed and rendered as a single document from the user's point of view.

 - Avoid proposing code edits unless I specifically tell you to do so.
 - When giving examples from my codebase, include the file name and line numbers so I can find the relevant code easily.
 
-## Code Style
+## Coding Guidelines
+
+### Prime Directive
+
+NEVER assume developer intent. If you are unsure about something, ALWAYS stop and ask the developer for clarification before proceeding.
+
+### AI Anchor Comments
 
-Observe the following style guidelines when writing code:
+- Use anchor comments prefixed with `AI-NOTE:`, `AI-TODO:`, or `AI-QUESTION:` to share context between AI agents and developers across time.
+ - Use all-caps prefixes.
+ - Also _read_ (but do not write) variants of this format that begin with `AI-<date>:` where `<date>` is some date in `MM/DD/YYYY` format. Anchor comments with this format are used by developers to record context.
+- **Important:** Before scanning files, ALWAYS search first for `AI-` anchor comments in relevant subdirectories.
+- ALWAYS update relevant anchor comments when modifying associated code.
+- NEVER remove `AI-` comments unless the developer explicitly instructs it.
+- Add new anchor comments as relevant when:
+ - Code is unusually complex.
+ - Code is critical to security, performance, or functionality.
+ - Code is confusing.
+ - Code could have a bug.
 
 ### General Guidance
 
+- Before writing any code, ALWAYS search the codebase for relevant anchor comments.
+- Whenever updating code, ALWAYS update relevant anchor comments.
+- Prefer to use Deno to manage dependencies, build the project, and run tests.
 - Use snake_case names for plain TypeScript files.
-- Use comments sparingly; code should be self-documenting.
+- Use comments sparingly; aim to make code readable and self-documenting.

+* Settings Panel Documentation
+
+** Overview
+The settings panel controls how events are fetched and displayed in the visualization. It has several sections that work together to create an efficient and user-friendly experience.
+
+** Event Types Configuration
+
+*** Purpose
+Controls which types of Nostr events are fetched and how many of each type.
+
+*** Key Event Types
+- *Kind 30040* (Index Events): Publication indices
+- *Kind 30041* (Content Events): Publication content
+- *Kind 30818* (Content Events): Alternative content format
+- *Kind 30023* (Content Events): Alternative content format
+
+*** How Limits Work
+Each event kind has a limit number that controls different things:
+
+**** For Kind 0 (Profiles)
+- Limit controls how many profiles to fetch from discovered pubkeys
+- These profiles are used for:
+  - Displaying names instead of pubkeys
+  - Showing profile pictures in tooltips
+  - When "People" tag anchors are selected, this limit controls how many people anchors to display
+
+**** For Kind 3 (Follow Lists)  
+- =limit = 1=: Only fetch the current user's follow list
+- =limit > 1=: Fetch the user's follow list PLUS (limit-1) follow lists from people they follow
+- The depth selector controls traversal:
+  - =Direct= (0): Just the immediate follows
+  - =2 degrees= (1): Follows of follows
+  - =3 degrees= (2): Three levels deep
+
+**** For Kind 30040/30041/30818
+- Limit controls maximum number of these events to fetch
+
+** Tag Anchors
+
+*** What Are Tag Anchors?
+Tag anchors are special nodes in the graph that act as gravity points for events sharing common attributes. They help organize the visualization by grouping related content.
+
+*** Tag Types Available
+- *Hashtags* (t): Groups events by hashtag
+- *Authors*: Groups events by author
+- *People* (p): Shows people from follow lists as anchor points
+- *Event References* (e): Groups events that reference each other
+- *Titles*: Groups events by title
+- *Summaries*: Groups events by summary
+
+*** How People Tag Anchors Work
+When "People" is selected as the tag type:
+
+1. The system looks at all loaded follow lists (kind 3 events)
+2. Extracts all pubkeys (people) from those follow lists
+3. Creates tag anchors for those people (up to the kind 0 limit)
+4. Connects each person anchor to:
+   - Events they authored (where pubkey matches)
+   - Events where they're mentioned in "p" tags
+
+*** Display Limiting and Auto-Disable
+- Tag anchors are created for ALL discovered tags
+- But only displayed up to the configured limit
+- When > 20 tag anchors exist, they're all auto-disabled
+- Users can selectively enable specific anchors
+- The legend becomes scrollable for many anchors
+
+*** "Only show people with publications" Checkbox
+When checked (default):
+- Only shows people who have events in the current visualization
+  
+When unchecked:
+- Shows ALL people from follow lists, even if they have no events displayed
+- Useful for seeing your complete social graph
+
+** Display Limits Section
+
+*** Max Publication Indices (30040)
+Controls display filtering for publication indices after they're fetched.
+
+*** Max Events per Index  
+Limits how many content events to show per publication index.
+
+*** Fetch if not found
+When enabled, automatically fetches missing referenced events.
+
+** Graph Traversal Section
+
+*** Search through already fetched
+When enabled, tag expansion only searches through events already loaded (more efficient).
+
+*** Append mode
+When enabled, new fetches add to the existing graph instead of replacing it.
+
+** Current Implementation Questions
+
+1. *Profile Fetching*: Should we fetch profiles for:
+   - Only event authors?
+   - All pubkeys in follow lists?
+   - All pubkeys mentioned anywhere?
+
+2. *People Tag Anchors*: Should they connect to:
+   - Only events where the person is tagged with "p"?
+   - Events they authored?
+   - Both?
+
+3. *Display Limits*: Should limits control:
+   - How many to fetch from relays?
+   - How many to display (fetch all, display subset)?
+   - Both with separate controls?
+
+4. *Auto-disable Threshold*: Is 20 the right number for auto-disabling tag anchors?
+
+** Ideal User Flow
+
+1. User loads the visualization
+2. Their follow list is fetched (kind 3, limit 1)
+3. Profiles are fetched for people they follow (kind 0, respecting limit)
+4. Publications are fetched (kind 30040/30041/30818)
+5. User enables "People" tag anchors
+6. Sees their follows as anchor points
+7. Can see which follows have authored content
+8. Can selectively enable/disable specific people
+9. Can increase limits to see more content/people
