zod

https://github.com/colinhacks/zod https://www.npmjs.com/package/zod

Author: Colin McDonnell zod@colinhacks.com License: MIT

The package's only runtime dependency. It is used to declare the shapes in src/data/schemas.ts and the internal state schemas, so a data table can be validated against its documented shape at runtime rather than only at compile time.

How it reaches you differs by artifact, and the distinction matters:

• The npm package REQUIRES zod. dist imports it and npm installs it alongside; no zod source is inside the tarball.
• The WebAssembly build BUNDLES it. wasm/build.mjs runs esbuild over dist, so zod's code is compiled into thetowersdk.wasm. Anywhere that file is distributed, this notice goes with it.

tower-idle-toolkit

https://github.com/tower-idle-toolkit/tower-idle-toolkit https://www.npmjs.com/package/tower-idle-toolkit

Author: skye License: ISC (declared in the published package manifest; the repository does not contain a separate LICENSE file)

Derived from tower-idle-toolkit:

• src/mechanics/wave-base-empirical-scaling.ts and src/mechanics/wave-scaling-regression-profile.ts — from statFormula.ts. The polynomial body, milestone-offset and compound-growth structure, the milestone divisors, and the HP/damage exponent bases originate there. Coefficients have since been refitted and the code restructured, but the approach and several constants are that project's work.
• src/mechanics/damage.ts — from damageFormula.ts.
• src/mechanics/bonuses.ts — from plusFormulas.ts.
• src/formatting/duration.ts — from formatTime.ts.

The Tower: Effective Paths (community spreadsheets)

Author: Matthew (matteweon on Discord) Source: https://docs.google.com/spreadsheets/d/1YwZtKP6B4WYhRba5T6APJ1YxKNdfnIGQnprgnxmO7zc

Portions of the game data in src/data/ -- particularly the reference tables and chart data (upgrade costs, mastery bonuses, substat ranges and related values) -- were compiled with the help of Matthew's "Effective Paths" spreadsheets for The Tower. That work saved an enormous amount of collation and is a large part of why these tables are as complete as they are.

Shared with the community as a reference; included here with thanks.

Author: Florent Castelli (Orphis) Source: private repositories, shared directly

The lab CATEGORIES in src/data/generated/labs-categories.generated.ts are read out of the game's own UI hierarchy rather than maintained by hand, and both the method and the asset-reassembly step it depends on were adapted from Orphis's extraction work with his permission. A lab's category is which container its UI tile is parented under; recovering it that way closed a gap in which six labs -- including all four module-stat labs -- shipped in the data and could not be rendered, because a hand-maintained list held 231 of the game's 253.

His independently produced lab names and localization tables were also used to cross-check ours; they agreed exactly, which is a large part of why this data is trusted. Licence terms to be formalised at his convenience.
