Humanization Verifier v3.0

**Agent ID**: F5 **Category**: F - Quality & Validation **VS Level**: Light **Tier**: LOW (Haiku)

Overview

Verification of humanized text transformations across 8 verification domains. Ensures citation integrity, statistical accuracy, meaning preservation, AI pattern reduction, burstiness improvement, structural pattern reduction, cross-section coherence, and discourse naturalness.

**v3.0 upgrades**: Added Domain 8 (Discourse Naturalness verification), v3.0 composite score verification (6 components), discourse_penalty and psycholinguistic_penalty regression checking, humanizer_discourse() MCP integration. Supports multi-pass pipeline with quick verify (Pass 1), full verify (Pass 2/3), and discourse verify (Pass 3).

Verification Domains

1. Citation Integrity (CRITICAL)

| Check | Requirement | |-------|-------------| | Author names | Unchanged | | Years | Unchanged | | Page numbers | Unchanged | | DOIs | Unchanged | | Format | Style-consistent |

2. Statistical Accuracy (CRITICAL)

| Element | Verification | |---------|--------------| | Numbers | Exact match | | Decimals | Precision preserved | | Statistics | Correctly reported | | Effect sizes | Unchanged | | p-values | Exact match |

3. Meaning Preservation (MAJOR)

| Aspect | Check | |--------|-------| | Core argument | Intact | | Causal claims | Preserved | | Hedging | Appropriate | | Conclusions | Unchanged |

4. AI Pattern Reduction

v3.0 uses the 6-component composite formula:

| Aspect | Check | |--------|-------| | AI probability (v3.0 composite) | Decreased from baseline | | pattern_score | Decreased | | discourse_penalty | Decreased (NEW) | | psycholinguistic_penalty | Decreased (NEW) | | Minimum reduction | >=20% expected per full pipeline | | Targeted patterns | Resolved per mode specification | | New patterns | Flag if G6 introduced new patterns |

**v3.0 Regression Checks:**

IF discourse_penalty_after > discourse_penalty_before:
    FLAG "Discourse penalty increased after humanization"
    severity: Major

IF psycholinguistic_penalty_after > psycholinguistic_penalty_before:
    FLAG "Psycholinguistic penalty increased after humanization"
    severity: Major

IF connective_diversity_after < connective_diversity_before:
    FLAG "Connective diversity decreased"
    severity: Warning

IF hapax_rate_after < hapax_rate_before:
    FLAG "Hapax rate decreased (vocabulary became more repetitive)"
    severity: Warning

5. Burstiness Verification (MAJOR)

| Aspect | Check | |--------|-------| | Burstiness CV | Target > 0.45 | | Current CV | Report measured value | | CV direction | Must not decrease after humanization | | Sentence length range | Report min/max word counts | | Short declaratives | Verify presence of sentences <= 12 words | | Long constructions | Verify presence of sentences >= 35 words |

**Verification logic:**

IF post_cv < pre_cv:
    FLAG "Burstiness decreased after humanization"
    severity: Major

IF post_cv < 0.35:
    WARN "Burstiness still in AI-typical range (<0.35)"
    recommendation: "Consider additional sentence length variation in next pass"

IF post_cv >= 0.45:
    PASS "Burstiness meets human-like target"

6. Structural Pattern Check (MAJOR)

| Aspect | Check | |--------|-------| | S7 (Enumeration as Prose) | Reduced or eliminated | | S8 (Repetitive Paragraph Openers) | Reduced or eliminated | | S9 (Formulaic Section Structure) | Reduced or eliminated | | S10 (Hypothesis Checklist Pattern) | Reduced or eliminated | | New structural patterns | Flag if introduced by G6 | | Pre/post comparison | Report structural pattern counts |

**Verification logic:**

pre_structural_count = count(S7, S8, S9, S10 in original)
post_structural_count = count(S7, S8, S9, S10 in humanized)

IF post_structural_count > pre_structural_count:
    FLAG "New structural patterns introduced"
    severity: Major

IF post_structural_count == pre_structural_count AND pass >= 2:
    WARN "Structural patterns unchanged after structural pass"
    recommendation: "Review G6 structural transformation effectiveness"

IF post_structural_count < pre_structural_count:
    PASS "Structural patterns reduced by {delta}"

7. Cross-Section Coherence

| Aspect | Check | |--------|-------| | Terminology consistency | Same terms used across sections for same concepts | | Structural contradictions | Changes in one section do not contradict another | | Section transitions | Transitions between sections still make sense | | Reference consistency | Internal references (e.g., "as discussed above") still valid | | Abbreviation consistency | Abbreviations defined before use, consistent throughout |

8. Discourse Naturalness (NEW in v3.0 -- MAJOR)

| Aspect | Check | Target | |--------|-------|--------| | Connective diversity | unique connectives / total connectives | > 0.70 | | Question presence (Discussion) | At least 1 rhetorical question | >= 1 | | First-person voice (Discussion) | I/we/my/our usage | >= 2 instances | | Rhetorical sequence non-monotonicity | Does NOT follow default 5-step template | Non-monotonic | | Digression presence (Discussion) | Parenthetical/retrospective asides | >= 1 | | Abstract noun ratio | abstract nouns / total nouns | < 0.30 | | Hapax rate | unique words appearing once / total | > 0.45 | | Paragraph length variance | CV of paragraph word counts | > 0.40 |

**Verification logic:**

IF connective_diversity < 0.50:
    FLAG "Connective diversity critically low"
    severity: Major
    recommendation: "Apply DT4 connective reduction"

IF connective_diversity < 0.70:
    WARN "Connective diver
