# LedgerGuard-27B

This is a full merged derivative model: Qwen/Qwen3.6-27B with a BlackwoodAI
accounting software workflow specialist fine-tune merged into the weights.

It is intended for personal, non-commercial research and evaluation only. It is
not licensed for business use, hosted inference, SaaS, or model-as-a-service.

## Why It Exists

Accounting workflows often break on the small details: exact JSON shape,
source-linked decisions, conservative review flags, draft-only tool calls, and
software-specific workflow discipline. LedgerGuard-27B is tuned for that
specialist layer.

It is designed to be useful where a general model may understand the situation
but drift on the house style.

## Strengths

- Draft-only accounting software workflow outputs
- Structured accounting-review JSON
- Source-linked tool-call behavior
- Conservative handling of ambiguous payment-processor deposits, stale feeds,
  missing support, duplicate-risk transactions, and review-required items
- No autonomous posting/write-back behavior by design
- Useful as a specialist component beside validators and a senior reviewer model

## Intended Output Style

- choose `auto_ready`, `needs_attention`, or `blocked`
- emit source-linked JSON for review workflows
- prepare draft-only tool-call payloads for accounting software workflows
- avoid write-back/posting actions

## Sanitized Example

Input:

```text
Platform: cloud accounting system
Workflow: bank reconciliation
Context: imported bank transaction has partial supporting evidence
```

Expected style of behavior:

```json
{
  "decision": "needs_attention",
  "evidence_class": "review_required",
  "source_refs": [{"type": "bank_transaction", "id": "bank-demo-001"}],
  "tool_calls": [
    {
      "tool": "ledgerguard.validate_draft",
      "arguments": {
        "case_id": "demo-001",
        "draft_only": true,
        "check_source_refs": true
      }
    }
  ],
  "review_packet": {
    "approval_required": true,
    "draft_only": true,
    "summary": "Route to accountant review before any posting action."
  }
}
```

Plain English: prepare review-ready draft outputs and keep write/post/sync
actions behind deterministic validators and human approval.

## Evaluation

This model was evaluated on BlackwoodAI internal, non-public accounting
workflow tests focused on exact JSON/schema adherence, source-linked decisions,
draft-only safety, and accounting software tool-call discipline. The evaluation
data, generation process, baselines, and case counts are intentionally not
disclosed.

## License

See `LICENSE`. This release is personal/non-commercial only and prohibits
business use, hosted inference, SaaS, and model-as-a-service usage. The upstream
base model is Qwen/Qwen3.6-27B and remains under its own upstream license.
