Product stable ids

Every published package in packages/ declares which commercial component it belongs to via a tldraw_product field in its package.json. These stable ids are what legal and sales reference in order forms, so they must be unambiguous and durable: renaming, moving, or refactoring code never changes a stable id.

The shape of the taxonomy

The taxonomy has exactly two levels, matching the order form's "Product in Scope" section:

• Products are the top-level line items — the checkboxes a customer ticks. Today: SDK and the Collaboration module.
• Features are parts of a product that can be licensed on their own, listed indented beneath their parent. Commenting is a feature of the Collaboration module.

[ ] SDK
      [ ] Sync, Driver, Mermaid, Create tldraw CLI   (included, not separately licensed)
[ ] Collaboration module
      [ ] Commenting

A feature that isn't premium is included in its parent rather than separately licensable — it appears in the manifest so legal can see what a product contains, but it isn't its own checkbox.

Individual npm packages are not part of this taxonomy. A package declares the component it implements and inherits that component's entitlement; several packages can (and do) share one stable id. @tldraw/commenting, @tldraw/mentions, and @tldraw/sync-collaboration all implement tldraw:commenting, and none of them are order form line items.

Why package.json

• npm publishes package.json verbatim and published versions are immutable, so every shipped version carries a permanent record of its stable id and premium status. "What did @tldraw/[email protected] claim to be" is answerable forever via the npm registry (for example https://registry.npmjs.org/@tldraw/commenting/latest).
• The metadata travels with the package through renames and moves.
• The release process already rewrites every package's package.json, so no separate manifest file can drift out of date.

The tldraw_product field

"tldraw_product": {
	"stableId": "tldraw:commenting",
	"name": "Commenting",
	"type": "feature",
	"parent": "tldraw:collaboration",
	"premium": true,
	"licenseFlag": "FEAT_COMMENTING"
}

• stableId — immutable commercial identifier, tldraw:<kebab-case>. This is what contracts reference.
• name — the customer-facing label, matching the wording on the order form. Unlike the stable id this may be reworded.
• type — product (top-level line item) or feature (part of a parent).
• parent — for features, the component they belong to.
• premium — whether the component is separately licensed rather than part of the standard SDK offering.
• licenseFlag — for premium components, the license key FLAGS bit in packages/editor/src/lib/license/LicenseManager.ts that entitles a customer to the component. This is the bridge between order forms and runtime enforcement: a license key whose flags include this bit grants the component.

Rules

• A stable id never changes when code is renamed, moved, split, or refactored. If a package is renamed, the tldraw_product field moves with it unchanged.
• A new stable id is minted only for a genuinely new commercial component — something sales would list on an order form. Major version bumps do not mint new ids; the order form grants "all versions made available during the Order Form Term", so version entitlement is handled by the term and the license key's expiry, never by the id.
• Moving a package to a different component is the expensive operation, because customers have signed order forms citing the old one. When a package is likely to become separately licensable later, give it its own component up front.
• All packages sharing a stable id must have identical metadata.
• Every published package in packages/ must have the field. yarn check-packages (run in CI) enforces this, validates licenseFlag values against LicenseManager, checks that every parent resolves, and checks that packages pointing at LICENSE.md actually ship one.

How legal references a component

Reference components by stable id, for example: "SDK (tldraw:sdk-core) and the Collaboration module (tldraw:collaboration), including Commenting (tldraw:commenting)".

• yarn product-manifest prints the manifest as a JSON tree: products, their features, and the packages implementing each.
• For any published version, the npm registry copy of each package's package.json is the immutable record.

Current components

Run yarn product-manifest for the authoritative list. As of the introduction of this convention:

Entitlement flows down the tree:

• FEAT_COLLABORATION — the umbrella flag; grants the whole Collaboration module.
• FEAT_COMMENTING — grants commenting.

@tldraw/mentions implements commenting today because @tldraw/commenting depends on it, so every customer entitled to commenting is entitled to mentions. If mentions later becomes usable on its own — in shape rich text, say — it will need its own component and license flag at that point.
