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

ifta-audit-defense 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 1mo 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.

IFTA Audit Defense

When an IFTA audit selects your carrier, defense matters. Goal: minimize additional tax + penalties.

Initial response (within 30 days of notice)

  • Acknowledge receipt
  • Request copies of audit notification
  • Ask for specific records they want to see
  • Note the audit period (which quarters)

Records to gather

  • Quarterly returns for the audit period
  • Fuel receipts (organized by quarter + state)
  • Mileage records (ELD or trip sheets)
  • Vehicle records (VINs, plate numbers, gross weight)
  • Tax-paid fuel logs
  • Sales invoices and receipts

During the audit

  • Auditor visits your office (or you ship records)
  • Sample period selected
  • Records reviewed in detail
  • Discrepancies identified
  • Adjustments calculated
  • Initial findings shared

How to defend

  1. Documentation quality — well-organized, complete records reduce audit time + findings
  2. ELD data — when available, ELD is highly persuasive
  3. Reasonable explanation — for any anomaly, have a story (driver took different route, weather event, etc.)
  4. Industry comparison — if your data is consistent with industry norms, that helps
  5. Personal use exclusion — if you exclude personal use, show your accounting

Common audit findings + defenses

  • Mileage shortfall: actual miles > reported. Defense: re-examine the data source; may be auditor error.
  • Fuel allocation off: state distribution doesn't match actual operation. Defense: provide route documentation.
  • Tax-paid double-counting: same fuel claimed twice. Defense: receipts show single purchase; cross-reference dates.
  • Personal use miles: claimed as business. Defense: provide written personal-use policy + driver records.

After the audit

  • No additional tax: you're done.
  • Small adjustment: pay it; document the change in your books.
  • Significant adjustment: request administrative review (state-level appeal).
  • Egregious finding or penalty: consider attorney representation.

Right of appeal

  • Administrative review (typically 30 days to request)
  • State-level hearing (varies by state)
  • Civil action (rare, time-consuming)

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.
