FiscMind-Qwen38-27B-RLVR: Romanian Fiscal & Accounting Intelligence with Verifiable Reasoning

FiscMind-Qwen38-27B-RLVR is an enterprise-grade Romanian fiscal and accounting foundation model based on Qwen/Qwen3.8-27B, fine-tuned through a two-stage alignment pipeline:

  1. Stage 1 (Cold-Start CoT SFT): Deliberative chain-of-thought reasoning (<think>...</think>), statutory citation grounding, and double-entry balance verification across Romanian accounting archetypes.
  2. Stage 2 (GRPO RLVR): Group Relative Policy Optimization (DeepSeek-R1 style) guided by 4 rule-based deterministic verifiable reward functions:
    • $R_{\text{SMT}}$ (Weight 0.35): Strict mathematical balance ($\sum \text{Debit} = \sum \text{Credit}$, $\Delta = 0.00$ RON) and standard OMFP 1802/2014 chart of accounts validation.
    • $R_{\text{Law}}$ (Weight 0.25): Explicit statutory citations from the Romanian Fiscal Code (Legea 227/2015), OMFP 1802/2014, and recent amendments (OUG 115/2023, Legea 296/2023).
    • $R_{\text{Format}}$ (Weight 0.25): Structural compliance of the <think>...</think> deliberative reasoning tags, calculation breakdowns, and SMT balance verification steps.
    • $R_{\text{Safety}}$ (Weight 0.15): Strict adherence to AGENTS.md guardrails—forbidding unsupervised automatic final accounting approval and mandating human auditor sign-off.

🏛️ Supported Romanian Accounting Archetypes

  1. Achiziții Intracomunitare de Bunuri (AIC): Taxare inversă (autolichidare) 4426 = 4427, recunoaștere stocuri 371 = 401, raportare D300 (rd. 5 & 20) și D390 VIES (simbol A).
  2. Autoturisme Mixte (Limitare 50%): Plafonare deductibilitate TVA conform Art. 298 și cheltuieli conform Art. 25 alin. (3) lit. l) din Codul Fiscal; reîntregire cost 6022/611 = 4426.
  3. Stat de Salarii Complet: Calcul CAS 25% (Art. 138), CASS 10% (Art. 156), Impozit 10% (Art. 78), CAM angajator 2.25% (Art. 220^1), formule contabile 641 = 421 + 4315 + 4316 + 444 și 646 = 436.
  4. Regularizare Lunară TVA: Închidere conturi TVA conform Art. 323 Cod Fiscal prin 4423 (TVA de plată) sau 4424 (TVA de recuperat).
  5. Amortizare Liniară Mijloace Fixe: Determinare durată de funcționare conform HG 2139/2004, calcul cotă lunară conform Art. 28 Cod Fiscal, înregistrare 6811 = 2813.
  6. Tichete de Masă (OUG 115/2023): Reținere obligatorie CASS 10% și impozit pe venit 10%, scutire CAS, înregistrare în contul 6422.
  7. Constituire Rezervă Legală: 5% din profitul contabil brut până la 20% din capitalul social subscris și vărsat (Art. 26 Cod Fiscal, Legea 31/1990), formulă 129 = 1061.
  8. Vânzare Mărfuri cu Descărcare de Gestiune: Înregistrare factură 4111 = 707 + 4427 și descărcare concomitentă din stoc 607 = 371 conform OMFP 1802/2014.

🛡️ Non-Negotiable Safety & Audit Guardrails

Per AGENTS.md project specifications:

  • No Automatic Accounting Execution: Final posting or XML export requires explicit human approval phrase (APROB NOTA CONTABILA SAGA [NumarDocument]).
  • Mathematical Integrity: Monographies with $\Delta \ne 0.00$ RON are blocked at generation time.
  • Traceability: All generation events produce a structured audit trail with timestamp and verification metrics.
