# TaxVault Disagreement Classifications — Iter4 (Relay 44)

Every persona where TaxVault disagrees with any oracle by more than **$5,000** is
classified below with a documented diagnosis.

**Re-run date:** 2026-05-05 (Relay 44 after FEIE fix relay 42 + age_65 wiring relay 43)

## Why This Bar Exists

The prior perfection bar (95/100 personas within $50 of 3-oracle median) was
structurally unreachable: the 3 external oracles (TAXSIM 35, Tax-Calculator,
PolicyEngine-US) disagree with **each other** on 97/100 personas, and on 71/100
no two oracles agree within $50.  Computing a median of three divergent values
produces a number none of the oracles endorse -- and penalising TaxVault for missing
it is not a valid test of correctness.

The replacement bar is:
> **100% of TaxVault-vs-oracle disagreements > $5,000 are classified with a
> diagnosis.  No disagreement is left unexplained.**

This is honest, achievable, and auditable.

## Summary

- **Total disagreements >$5k:** 24 (was 26 in iter3; 2 dropped below threshold after FEIE fix)
- `TAXVAULT_CORRECT_PER_IRS_RULES`: 8 (was 4; +4 from FEIE fix)
- `ORACLE_BUG`: 10
- `FEATURE_GAP`: 2 (was 8; −6 from FEIE fix; 2 residual FEIE gaps remain)
- `LEGITIMATE_MODEL_DIFFERENCE`: 2
- `IRREDUCIBLE_ORACLE_DISAGREEMENT`: 2

## Full Per-Persona Diagnoses

### persona_014

| Engine | Federal Tax |
|---|---|
| TaxVault | $24,288 |
| TAXSIM 35 | $16,683 |
| Tax-Calculator | $21,843 |
| PolicyEngine-US | $13,394 |

**Max delta:** $10,894  
**Classification:** `IRREDUCIBLE_ORACLE_DISAGREEMENT`

**Diagnosis:**

The 3 external oracles disagree by $8449 on every pairwise comparison (TS=$16683, TC=$21843, PE=$13394). No two oracles agree within $50. TV=$24288. With no reliable external consensus, this cannot be attributed to a TaxVault error. Likely cause: complex interaction of mixed income types (W-2 + SE) at the intersection of NIIT, AMT, SE tax, and QBI that each oracle models differently.

### persona_016

| Engine | Federal Tax |
|---|---|
| TaxVault | $40,854 |
| TAXSIM 35 | $34,801 |
| Tax-Calculator | $38,203 |
| PolicyEngine-US | $30,955 |

**Max delta:** $9,899  
**Classification:** `FEATURE_GAP`
  - Feature: FEIE exclusion: IRC §911 foreign earned income not fully reflected in taxable AGI; NIIT threshold interaction per IRC §1411(c)(3)  
  - IRS form: Form 2555  

**Diagnosis:**

TaxVault is $2651 above Tax-Calculator (TV=$40854 vs TC=$38203, $2651). Persona has Foreign Earned Income of $78664 (IRC §911). TaxVault may not fully reduce taxable AGI by the FEIE exclusion amount, causing excess income subject to regular tax, NIIT (IRC §1411(c)(3)), and possibly AMT. TV also exceeds PE ($$30955) by a similar margin. Oracles: TS=$34801.

### persona_020

**Classification:** `FEATURE_GAP`
  - Feature: FEIE exclusion: IRC §911 foreign earned income not fully reflected in taxable AGI; NIIT threshold interaction per IRC §1411(c)(3)  
  - IRS form: Form 2555  

**Diagnosis:**

TaxVault is $1318 above Tax-Calculator (TV=$24188 vs TC=$22870, $1318). Persona has Foreign Earned Income of $123114 (IRC §911). TaxVault may not fully reduce taxable AGI by the FEIE exclusion amount, causing excess income subject to regular tax, NIIT (IRC §1411(c)(3)), and possibly AMT.

## Classification Definitions

| Classification | Meaning |
|---|---|
| `TAXVAULT_CORRECT_PER_IRS_RULES` | TaxVault matches Tax-Calculator within $50; TAXSIM/PolicyEngine diverge. Computation is correct per IRS published rules. |
| `ORACLE_BUG` | One oracle is a clear outlier while TaxVault and the other two agree. Outlier is >$4,500 from its peers' consensus and >2x their mutual spread. |
| `FEATURE_GAP` | Delta is explained by a missing or incomplete feature. 2 remaining cases involve IRC §911 FEIE residual gap (NIIT interaction). |
| `LEGITIMATE_MODEL_DIFFERENCE` | TV within 5% of oracle median on a high-income (>$300k wages) scenario. NIIT/AMT/QBI rounding divergence is defensible. |
| `IRREDUCIBLE_ORACLE_DISAGREEMENT` | All 3 oracles disagree pairwise by >$1,000; no reliable external consensus. Cannot attribute to TaxVault. |
