Invalid whale point asset.

Error message

Invalid whale point asset.

What it means

Thrown after successfully fetching `whale-points.tsv` when the parsed data does not have exactly 980 rows or any row does not contain exactly two finite numbers. This validates the whale geometry asset's strict format before building the world.

Solutions

1. Restore the original 980-point, two-column whitespace-separated `whale-points.tsv`.
2. Re-export the asset from the tool that generates it and re-count rows/columns.
3. Strip headers/comments/blank lines and ensure every row has exactly two finite numeric values.

Example fix

// before: 979-point asset
// after: validate before shipping
const rows = text.trim().split('\n');
if (rows.length !== 980 || rows.some(r => r.trim().split(/\s+/).length !== 2)) throw new Error('regenerate asset');

const rows = tsv.trim().split('\n');
const ok = rows.length === 980 && rows.every(r => { const c = r.trim().split(/\s+/); return c.length === 2 && c.every(v => Number.isFinite(Number(v))); });
if (!ok) throw new Error('bad whale-points.tsv');

const isPoint = (p: unknown[]): p is [number, number] => p.length === 2 && p.every(Number.isFinite);

try { points = parseWhalePoints(tsv); } catch (e) { showFatal('Whale asset is corrupt: regenerate it.'); }

When it happens

Trigger: The TSV is corrupted, truncated, has extra/missing columns, or was replaced with a file of a different point count; whitespace/encoding changes produce non-numeric values (`NaN` from `Number`).

Common situations: Editing or regenerating the asset with a script that changes point count, uploading a stale asset from another version, files saved with headers or comments.

Understand the failure class

Background: Schema validation failed / invalid input schema: payload rejected because its shape doesn't match the expected schema — this error's family across 28 libraries.
