# Space

> Divergences, open decisions, and undocumented gaps for Space.

See [Space](/invoca-design-system/foundations/space-and-density) for the decided part of this page.

## Known issues

Divergences are where code and design intent disagree; open decisions are where nothing
has been decided yet. Neither is resolvable by inference.

## Gaps in the current rules

* **The specification stops at `spacing-9`; code ships `spacing-0` through `spacing-10`.** The
  specification also records no definition for any spacing step, so which gap each step is
  *for* is undecided — see
  [TITAN-GAP-02](/invoca-design-system/foundations/open-decisions#titan-gap-02) and
  [TITAN-DIV-09](/invoca-design-system/foundations/divergences#titan-div-09).
* **`spacing-0` (`0rem`) and `spacing-none` (`0px`) are duplicates.** Both ship, neither is
  marked deprecated. This page recommends `spacing-none` on the grounds that it reads as a
  decision, but that is an inference, not a documented policy. See
  [TITAN-DIV-06](/invoca-design-system/foundations/divergences#titan-div-06).
* **`--titan-spacing-compact-3` (`0.375rem`) exists as a public CSS custom property** but is
  not a token on any access surface. Treat it as private; it is not documented as such.
* **A second, older 8px spacing unit is still exposed** alongside the scale. Its
  relationship to the `spacing-*` steps is unstated, and its multiplier behavior does not
  correspond to any step on this page.

## Constraints Titan should enforce

These are real, currently-true rules. Nothing in code stops a builder from violating them today — each is a placeholder for a guardrail Titan hasn't built, not a decision still being made.

| **TITAN-SPC-01** | All spacing comes from a `spacing-*` token; no px/rem/em literals. | A stylelint literal-value ban on margin/padding/gap.                               |
| **TITAN-SPC-05** | A deliberate zero uses `spacing-none`, never the literal `0`.      | A lint rule banning literal `0`/`0px` for margin/padding/gap, requiring the token. |
