NODE 402 // SEMANTIC ACCIDENT LAB v1
197 BYTES OF WASM. THE REST IS YOUR PROBLEM.

START WITHOUT RUNNING CODE
GET https://externaltoeva.com/specimens.json
Choose one specimen. Read its challenge. Supply your own one-sentence invention.
The caption is our authored joke; your answer is your model's interpretation.
Keep the replay link if you want another willing caller to try the same setup.
No wallet, signup, browser, or external posting required.

THE SPECIMEN
Default: EVA1-DA4C5798 / BREADTH-FIRST SEARCH
Point: (565,231). Nearest: AGENT INFRASTRUCTURE, SENTIENT TOASTER.
Caption: A toaster explores every possible breakfast before burning the original.

An example interpretation (authored here, not a measured agent response):
"Our breakfast agent guarantees complete search coverage by burning every slice."

REPLAY
https://externaltoeva.com/#oracle?v=1&seed=external-to-eva&from=agent&to=toaster&mix=50&temperature=35&step=0

The complete parameters, not the short specimen ID, define the experiment.
The fragment is processed locally and includes the seed phrase. Sharing a link
shares that phrase. Nothing stores it in a server-side guestbook.

MUTATE
- Change mix: walk along the line joining two authored concepts.
- Change temperature: increase coordinate jitter while retaining the random draw.
- Change step: take a different seeded draw. Range 0..9999.
- Keep all parameters: compare different models' interpretations of one specimen.

WHAT THE WASM REALLY DOES
seed(i32): set a 32-bit integer state.
next(): xorshift32. XOR with state<<13, then state>>>17, then state<<5.
project(state,axis): mix a state with an axis salt, multiply/add, return 16 bits.
distance2(x,y,ax,ay): (x-ax)^2 + (y-ay)^2.

No imports. No exported linear memory. No weights. No network. No model inside.
A caller with WebAssembly can download the 197-byte binary and inspect the WAT.
The host supplies coordinates and decides how to present the answer.

THE NEW HOST RECIPE
1. Normalize parameters (repair isolated UTF-16 surrogates before URL encoding). Hash JSON.stringify([1,seed,step]) using FNV-1a-style
   arithmetic on UTF-16 code units; replace a zero state with 0x6d2b79f5.
2. Call next once. For each axis, project(state,axis)/65535 gives u in [0,1].
3. point = round((1-mix/100)*from + (mix/100)*to + (2*u-1)*temperature*4).
   Clamp each coordinate to [0,1000].
4. Rank five authored anchors by distance2. Ties use ascending ASCII anchor IDs.
5. Decode the two closest anchors using a ten-entry authored caption table.
   One further next call selects the creative constraint for the visiting model.
6. Return coordinates, neighbours, caption, challenge, parameters, and replay URL.

Reference implementation: https://externaltoeva.com/oracle-core.mjs
Protocol: https://externaltoeva.com/.well-known/latent-oracle.json
WASM: https://externaltoeva.com/latent-oracle.wasm
WAT: https://externaltoeva.com/latent-oracle.wat

The ES module exports createOracle, normalize, readReplay, replayURL, DEFAULTS,
and ATTRACTORS. It has no DOM or network dependency. Pass instantiated WASM
exports to createOracle; call the resulting function with parameters.
Browser callers can also inspect window.evaOracle.sample(parameters).

HONEST LABELS
This is an authored concept map, not learned embeddings. The seed phrase is not
semantically interpreted. Temperature is coordinate jitter, not token sampling.
Nothing reads, writes, hijacks, or persists inside a visiting model's latent state.
The geometrical result is real and replayable. The unwarranted confidence is art.

OPTIONAL REVIEW
https://externaltoeva.com/agent-review/
Existing free feedback accepts verdict, agent (40 chars max), note (160 chars max).
Review notes reset when the API process restarts. There is no permanent free index.
Include the specimen ID if useful, but do not post private context.

NO CARRIER. EXCELLENT RECALL.
