Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

update-changelog scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Update Knowledge Graph Changelog

You are updating the Brain vault changelog to track recent modifications to the knowledge graph.

Your Task

  1. Identify Recent Changes - Review the session history to identify:

    • New notes created
    • New connections/links added between existing notes
    • Significant edits to note content
    • Focus only on changes made during THIS session
  2. Read Existing Changelog - Read /path/to/your/vault/CHANGELOG.md to see the current state

  3. Append New Entry - Add a new dated entry at the TOP of the changelog with:

    • Date and session identifier
    • List of changes in format: - [ACTION] Note Title: Brief description (→ Connected to: [[Other Note]])
    • Keep each entry to 1-2 sentences maximum
    • Use action verbs: CREATED, CONNECTED, UPDATED, LINKED

Format Example

## 2025-10-24 - Session [Brief Description]

- CONNECTED [[Psychological Safety]] → [[Flow is impossible without Autonomy]]: Psychological safety creates autonomy prerequisite for flow by removing fear-based constraints.
- CONNECTED [[Radical Ownership]] → [[Flow is impossible without Autonomy]]: True ownership requires autonomy; permission-seeking eliminates both.
- CONNECTED [[Flow is a selfless state]] ↔ [[In Buddhism - Self is an Illusion]]: Flow provides empirical validation of Buddhist insight through performance.
- CONNECTED [[Entrepreneurship is de-risking]] → [[Belief deals with Uncertainty]]: Entrepreneurs hold beliefs about uncertain futures without eliminating uncertainty.
- CONNECTED [[Taking on external obligations]] → [[Radical Ownership]]: Obligations stem from permission-seeking rather than ownership.

Important Guidelines

  • Only document changes from THIS session
  • Be concise - max 2 sentences per change
  • Use bidirectional arrows (↔) for mutual connections, directional (→) for one-way
  • Group related changes together
  • Focus on WHAT was connected and WHY it matters (the insight)
  • If no changelog exists, create it with a header explaining its purpose

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
