docs(taxonomy): #498 AIF cluster « Attaque personnelle » — second undermine-dominant, most uniform (7 leaves, proposition)

[jsboige]

What

Idle-lane deliverable (dispatch msg-9akcg4 + ai-01 ACK msg-6uufhx naming this exact candidate: "Attaque personnelle undermine-dominant PTK-adjacent — bon choix"). Sixth Layer C cluster, following #837/#839 (mixed), #840 (cigogne), #841 (accident), #843 (inconsistance). « Attaque personnelle » (Obstruction > Ad hominem). 7 unmapped leaves (1399-1405) under anchor 1398 — serialized undermine/I-node WITH native skos (DirectAdHominem_Inference, skos:broadMatch).

The cluster's distinctive character — second undermine-dominant, the most uniform

Second undermine-dominant cluster (after #843 Inconsistance), and the most uniform: all 7 leaves share the same attack-type (undermine/I-node), the same scheme (DirectAdHominem_Inference), and the same mechanism (discredit the source rather than refute the position). The sub-sub is a pure rhetorical-vector family — the channel of attack varies, the AIF mechanism does not.

7/7 native-fit (100 %) — highest rate, tied with accident #841. The DirectAdHominem_Inference token (natively attested, the anchor's own scheme) captures exactly the "attack the person, not the position" mechanism. No fail-loud, no fabrication. Legitimate scheme inheritance (leaves share the anchor's mechanism, distinct from the attack-type-inheritance warning).

The 7 leaves — variety is the attack vector (the rhetorical channel)

pk	text_fr	attack vector
1399	Argument tonal	tonal (manner of presentation)
1400	Dérision	mockery (ridicule)
1401	Raillerie	mockery (taunt)
1402	Diffamation	reputation (poisoning the well)
1403	Injure	abuse (hurtful language)
1404	Insulte	abuse (offense)
1405	Lancer de soulier	contempt gesture (non-verbal) — boundary

• 7/7 native-fit (inherit DirectAdHominem_Inference) — legitimate skos inheritance.
• Uniform undermine/I-node (7/7) + uniform scheme — the most uniform cluster in the chantier.
• Axiom 0 violation (7 undermine→I).

Distinctive leaves

• 1402 Diffamation = poisoning the well (pre-emptive reputation attack to discredit the source before they speak) — canonical direct ad-hominem form, bridges to the separate "Empoisonner le puits" queue candidate.
• 1405 Lancer de soulier boundary = the only non-verbal leaf (a contempt gesture). Modelled undermine/I-node honestly (the gesture discredits the source by signalling disdain), flagged for ratification — ai-01/jsboige may prefer to read it as outside the AIF argument-space.

The chantier's pattern catalog — AIF spectrum now fully covered

pole	cluster	variety axis
rebut	#760 Relativisme	—
undercut, native-rich, scheme-diverse	#841 accident	4 Walton schemes
undercut, native-rich, mono-scheme	#840 cigogne	native-fit / fail-loud
mixed-type	#837 / #839	sub-mechanism split
undermine, mono-scheme, contradiction-shape	#843 inconsistance	pair / self-ref / cumulative / n-ary / premise↔conclusion
undermine, mono-scheme, attack-vector	this	tonal / mockery / reputation / abuse / gesture

The two undermine-dominant clusters bracket the mono-scheme undermine space (contradiction-shape variety + attack-vector variety).

Changes

1. docs/taxonomy/498-aif-attaque-personnelle-cluster.md — cluster doc.
2. docs/taxonomy/498-aif-attaque-personnelle-annotations.csv — 8 rows (anchor + 7 leaves), 12 cols.

Scope / posture

• PROPOSITION ONLY, 0 prod CSV write (post-T&A). Serialization deferred to gated apply after jsboige ratifies.
• 0 fabrication — DirectAdHominem_Inference verified native (anchor 1398); ad-hominem family native-rich (CircumstantialAdHominem_Inference, PositionToKnow_Inference, Bias_Inference all attested). Read-only docs lane. Post-tag-safe.
• Verdict QA = ai-01.
