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

corporate-network-analysis 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 12d 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.

Corporate Network Analysis

Exploit slow information diffusion through supply chain relationships and director interlocks to identify predictable stock returns. Academic research shows customer momentum yields ~150bps monthly alpha; board centrality generates ~4.68% annual risk-adjusted returns.

Core Investment Theses

  1. Supply Chain Momentum: When a customer gets a big order, upstream suppliers benefit with a lag (40% of shock diffuses over subsequent months)
  2. Director Interlock Signals: Shared board members facilitate information flow, M&A activity, and strategic alignment
  3. Cross-Holding Synergies: Executives/directors with positions in multiple companies may orchestrate beneficial strategic moves

Workflow

Phase 1: Identify Target Company Networks

1. Map supplier-customer relationships (>5% revenue materiality)
2. Identify board members and their other directorships
3. Track executive cross-company positions
4. Document insider holdings across connected firms

Phase 2: Data Collection

Use free data sources in this priority order:

Relationship Type Primary Source How to Access
Suppliers/Customers SEC 10-K Item 1/7 EDGAR full-text search
Board Members DEF 14A Proxy EDGAR company filings
Insider Transactions Form 3/4/5 EDGAR insider filings
Beneficial Ownership Schedule 13D/13G EDGAR ownership filings
Institutional Holdings Form 13F EDGAR quarterly filings

See references/sec-data-guide.md for detailed extraction procedures.

Phase 3: Network Construction

Build network graphs connecting companies through:

  • Customer-supplier links (weighted by revenue %)
  • Shared directors (first-degree: direct; second-degree: shared third board)
  • Executive overlaps
  • Cross-insider holdings

Calculate centrality metrics:

  • Degree: Number of direct connections
  • Betweenness: Importance in information flow paths
  • Closeness: Speed of information propagation

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.
