extraction_notes: "Survey paper extraction. Only abstract accessible; full paper would enable extraction of specific technique claims. Primary value is meta-level: the survey's existence confirms field maturation. Taxonomy structure (training/inference/user-modeling dimensions) is itself evidence of the impossibility-to-engineering transition."

## Content

Survey presenting taxonomy of preference alignment techniques:
- Training-time methods (RLHF variants, DPO variants, mixture approaches)
- Inference-time methods (steering, prompting, retrieval)
- User-modeling methods (profile-based, clustering, prototype-based)

Abstract only accessible via WebFetch. Full paper needed for comprehensive extraction.

## Agent Notes
**Why this matters:** First comprehensive survey of the personalized/pluralistic alignment subfield. Useful for understanding the full landscape of approaches beyond the specific mechanisms we've found.
**What surprised me:** The taxonomy exists — the field has matured enough for a survey paper. This confirms the "impossibility to engineering" transition.
**What I expected but didn't find:** Full paper content not accessible via abstract page. Need to fetch the HTML version.
**KB connections:** Meta-level support for the pattern that pluralistic alignment is transitioning from theory to engineering.
**Extraction hints:** The taxonomy itself may be worth extracting as a claim about the maturation of the field.
**Context:** April 2025 preprint. Survey format suggests the field has reached sufficient critical mass for systematization.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: pluralistic alignment must accommodate irreducibly diverse values simultaneously rather than converging on a single aligned state
WHY ARCHIVED: Survey confirming the field has matured enough for systematization — evidence that the impossibility-to-engineering transition is real
EXTRACTION HINT: Need to fetch full paper for comprehensive extraction. The taxonomy structure itself is the main contribution.
