  reasoning: 'The bare structure — a representation whose meaning is recoverable only from one privileged position in the space of vantages and degraded or scrambled from every other — is medium-neutral, so structural abstraction is a 4 (it does not require pixels or paint). It recurs beyond visual art: an encrypted message readable only with the one correct key, a signal legible only from a specific reference frame or observation angle, a password-gated resource that resolves to sense only for the holder of the credential. But most of the crisp, self-consciously-named evidence sits in the visual/optical home (holbein skull, cylindrical mirror anamorphs, street pavement art), and the transfers to cryptography/access are arguably better named by `encoding`/`key` primes, so domain breadth is 3 and transfer evidence a candid 2. Composite 3: a real structure but with a strong pull back toward its art-domain instance.'

  rationale: 'The underlying relation — coherence conditional on a single privileged vantage — is a pure structural fact about a mapping and carries no normative weight, so evaluative_weight is near zero. But the name "anamorphosis" and much of its recognized instancing are bound to a human visual-art practice (a viewer physically moving to the resolving spot), which lifts vocab_travels and human_practice_bound off the floor: outside painting and optics one tends to *import* the metaphor rather than *recognize* the same word. It reads mixed-structural: a genuine viewpoint-conditional structure wearing a strongly art-marked coat.'

# Anamorphosis

## Core Idea

Anamorphosis is the structure of a representation that is *coherent from exactly one privileged vantage and distorted, scrambled, or meaningless from every other*. It occupies one pole of a single axis — *how a representation's legibility depends on the observer's position* — whose opposite pole is `perspective`. Perspective encodes depth so that it reads as coherent space from a general or reconstructable viewpoint; a perspective picture looks like a plausible scene from anywhere in a wide viewing zone, and the rules that build it are viewpoint-*general*. Anamorphosis inverts exactly this: the encoding is deliberately tuned so that the intended form resolves *only* when the observer occupies one specific station point (or applies one specific transforming device — a cylindrical mirror, a precise angle), and collapses into apparent nonsense the instant the observer stands anywhere else. The load-bearing move is not "distortion" as such but *conditional resolution keyed to a single vantage*.

Three commitments travel with the pattern. First, a **space of vantages** — the set of positions or transforms from which the representation could be observed, over which legibility is defined and (crucially) non-uniform. Second, a **privileged element** of that space: exactly one vantage (or a thin set) at which the encoding inverts back to the intended form. Third, a **conditional payload**: the intended content is genuinely *present in the surface everywhere*, but *recoverable only at the privileged vantage* — it is not hidden by omission but by projection, so an observer at the wrong vantage sees real marks that simply do not cohere. The characteristic payoff is *access control by geometry*: the meaning is public in the sense of fully inscribed on the surface, yet private in the sense that reading it requires knowing and occupying the one resolving position. The characteristic cost is *fragility and single-point dependence*: the representation buys its striking one-vantage effect by being useless — or actively misleading — from all the vantages an ordinary representation would serve, so it sacrifices the robustness that viewpoint-general encodings enjoy.

Read structurally, the same object appears wherever a signal is engineered to make sense under exactly one transform and to resist all others. In **optics and geometry** it is the projective transform that a cylindrical or conical mirror (or a single oblique sightline) exactly undoes. In **cryptography** the analogue is a ciphertext that resolves to plaintext under one key and to noise under every other — the "privileged vantage" is possession of the key. In **perception and cognition**, a figure that snaps into recognition only from one interpretive frame (or one physical angle) and stays inert otherwise runs the same conditional-resolution structure. Across substrates the recognizable move is identical: inscribe the payload everywhere on the surface, but arrange the projection so that legibility is *conditional on occupying the one privileged element of the vantage space* — the exact dual of perspective's promise that coherent form is available from wherever a viewer reasonably stands.

## Notes

**Provenance.** Produced by op-01 dualization, sub-flavor 1c, as the dual of `perspective` (input one_liner "Representation of depth") along the viewpoint-invariance axis. Where perspective delivers coherent depth from a general/reconstructable station point, its 1c dual delivers coherent form from *exactly one* privileged station point — image resolving only from a single viewpoint. Single-route proposal in the sweep; no independent convergence, which is itself a signal to weigh (see below).

**For owner evaluation (keep/cut).** The case FOR: there is a clean, nameable structural axis here — *viewpoint-general legibility vs. single-vantage-conditional legibility* — and anamorphosis is the sharp, historically-established name for the far pole, so the dualization is real rather than a restatement of `perspective`. The conditional-resolution structure (payload fully inscribed, recoverable only under one privileged transform) also has a legitimate abstract reading that reaches cryptography and access-control. The RISKS, which are the reason for the HOLD: (1) **art-domain-instance risk** — anamorphosis is a famous *visual-art technique* (Holbein's *The Ambassadors* skull, mirror anamorphs, pavement art), and the danger is that the "prime" is really just that technique with a domain-general veneer, i.e. an instance masquerading as a pattern (the diffusion-for-`random_walk` failure mode). Its cross-domain instances are thinner and more metaphor-like than a strong structural prime's, and the frontmatter scores reflect that honestly (SI composite 3, transfer_evidence 2). (2) **Screen-overlap / better-genus risk** — the non-art readings (one-key-resolves ciphertext, credential-gated access) may be more faithfully captured by existing `encoding`/`encryption`/`key_and_lock`-type primes than by anamorphosis; if so, the distinctive residue is exactly the art technique, which argues cut-or-fold. (3) **Genus question** — even if kept, the better hold might be a broader *viewpoint-conditional / reference-frame-relative representation* prime, with anamorphosis as its aesthetic exemplar rather than the prime itself. There IS a genuine pair-completion signal (it cleanly completes the viewpoint-invariance axis opposite `perspective`), which is the strongest argument for keeping something here; the open question is whether the something is anamorphosis or a de-arted parent.

**At incorporation.** Re-run similarity against `perspective` (sibling/dual), and against any `encoding`/`encryption`, `key_and_lock`/access-control, and reference-frame/viewpoint primes to test whether the non-art content collapses into an existing prime. If it survives, decide keep-as-anamorphosis vs. abstract-to-a-viewpoint-conditional-genus; draw the sibling edge to `perspective` along the viewpoint-invariance axis and the proposed-parent edge to whatever genus is chosen. Then write the body sections (Structural Signature onward) and sync the final one_liner to a v1 draft per CLAUDE.md before merge.
