Notes for Reviewers

This PR replaces DESIGN.md's prose-only styling notes with a structured, source-verified design contract intended to be consumed reliably by both human contributors and AI coding agents.

  • 5-Layer Implementation Model: Introduces an explicit architectural model (Formal Design Token → Canonical Theme Path → Active Component Convention → Legacy/Compatibility Path → Observed Implementation Literal) so guidance no longer conflates token declarations with runtime component implementations.
  • Source-Verified Token Mappings: Adds explicit token-to-implementation mapping tables for colors/surfaces, spacing, border radii, typography, and shadows/elevation with verified source file citations.
  • Contract & Guardrail Sections: Adds an Interaction States Matrix, an Authorization & Permissions section (clarifying <PermissionProvider> requirements), Responsive & Accessibility guidance (including modal dialog ID collision mitigation), an AI coding guardrails section, and a drift protocol.
  • Canonical Code Recipes: Provides two verified code recipes (Card and Authorization-Controlled Action Button using PermissionKeySpec for single or composite permissions).
  • Token Accuracy: Corrects the stale surface-dark-card token value from #121212 to #212121 to match the actual rendered literal.
  • NPM Package Distribution: Adds DESIGN.md to files in package.json so downstream repositories (like Meshery and Recognition) can resolve node_modules/@sistent/sistent/DESIGN.md directly.

This PR fixes #1837

📝 Walkthrough

Walkthrough

DESIGN.md now defines framework metadata, updated design tokens, canonical MUI mappings, component conventions, accessibility and authorization rules, implementation recipes, AI guardrails, and drift procedures.

Changes

Design contract

Layer / File(s) Summary
Token metadata and implementation mappings
DESIGN.md
Adds framework and package metadata, changes surface-dark-card to #212121, and documents canonical color, spacing, radius, typography, and elevation mappings.
Component and interaction guidance
DESIGN.md
Documents component import precedence, interaction states, authorization, responsive behavior, accessibility, and ContentCard, ProtectedActionButton, and modal recipes.
AI guardrails and drift procedures
DESIGN.md
Adds rules for token translation, component usage, permissions, dark mode, typography, documentation drift, audits, and design do/don’t guidance.

A few smaller things I noticed that aren't blocking, but would be good to clean up:

  • DESIGN.md L374: src/theme/components/button.modifier.ts doesn't reference background.cta, so I think the citation should be palette.ts only.

  • DESIGN.md L429: checkbox.modifier.ts doesn't set the 2px radius. That value comes from rx="2" in src/icons/Checkbox/CheckboxIcon.tsx:28, so the citation should point there instead.

  • DESIGN.md L22: surface-light-card: '#FFFFFF' doesn't match the current code. Light-mode background.card is Colors.charcoal[100]. The dark value was corrected in this PR, but the light value needs the same correction. The same issue appears again at L380.

  • DESIGN.md L602: @mui/utils isn't a direct dependency in package.json. The repo has direct dependencies on @mui/material, @mui/system, @mui/icons-material, and @mui/x-date-pickers, but not @mui/utils. Consumers copying this import could therefore run into a missing-module error.

All of these have been cleaned up and pushed in the latest commit. Thanks for the thorough review @hiyach28 !

Thanks for the quick turnaround, @PARTH-TUSSLE. I re-checked the latest commit and every point from my earlier review is resolved
Two points tho:

  1. L530: the note says per-instance modal ID forwarding "is tracked as an upcoming component enhancement", but I couldn't find an issue for it. Could you open one and link it here, or reword to "not yet tracked"? Otherwise anyone who follows the note, person or agent, has nothing to find.
  2. L430: rounded.sm cites src/theme/theme.ts for theme.shape.borderRadius, but that file doesn't set shape, so the 4px comes from MUI's default theme. Citing "MUI default (not overridden in src/theme/theme.ts)" would be more accurate.

Thanks for catching those @hiyach28! Just pushed an update addressing both:-
1.Reworded the modal note to "not yet tracked as a dedicated issue".
2.Updated the rounded.sm citation to accurately note it's the MUI default (not overridden in src/theme/theme.ts).

Is the "DESIGN.md" addition to files planned as a follow-up? Right now files is ["dist"] (0.22.6's tarball contains only LICENSE, README, package.json and dist/*), so the node_modules/@sistent/sistent/DESIGN.md path in meshery/meshery#21987 and layer5io/recognition#119 won't resolve. Would be good to link it here?

Reviewd the PR, have identified one blocking issue and a few minor ones.

imp: the permissions section and the permission-button example (Recipe 2) say an unauthorized button "automatically disables itself." That's only true if the app is wrapped in PermissionProvider, and the doc never mentions it. Without a provider, useHasPermission in src/custom/PermissionProvider.tsx:194 returns true, so nothing is gated. Anyone who copies the example into an app without a provider gets a "protected" button that works for every user, with no warning. hence, can add a line telling readers to wrap the app in PermissionProvider.

Smaller issues (non-blocking):

  • DESIGN.md:380 labels background.card with a layer name that isn't one of the five layers the doc defines.
  • The note at DESIGN.md:530 about duplicate modal IDs describes the problem but doesn't tell readers what to do.
  • Recipe 2 types the permission prop as a single key, but the component also accepts anyOf/allOf sets.
  • The PR description still says "three recipes"; the doc now has two.

Thanks for the reviews, @hiyach28 and @Maanvi212006! All points have been addressed in the latest commit:

  1. PermissionProvider Requirement: Added explicit notes in both Section 6 and Recipe 2 stating that <PermissionProvider> must wrap the application tree for permissionKey gating to take effect (as useHasPermission intentionally defaults to true without a provider).
  2. Layer Classification at L380: Fixed Active Component Binding to Active Component Convention to match the five defined layers.
  3. Modal ID Accessibility at L530: Added actionable consumer guidance advising developers to conditionally mount dialog instances ({isOpen && <Modal ... />}) to prevent duplicate-ID collisions in the accessibility tree.
  4. Recipe 2 Prop Typing: Updated permissionKey in Recipe 2 to type PermissionKeySpec (imported from @sistent/sistent), supporting both single keys and composite anyOf/allOf sets.
  5. Recipe Count: Corrected the PR description to reference two canonical recipes.
  6. Packaging DESIGN.md: Added "DESIGN.md" to "files" in package.json so downstream consumers can resolve node_modules/@sistent/sistent/DESIGN.md directly.
