+# HR Workspace Job grade review accessibility references
+
+Checked against current primary W3C publications on 2026-08-28. These references support interaction semantics only; they do not establish HR, compensation, or employment-decision authority.
+
+## Design implications
+
+- WAI-ARIA 1.2 defines `status` as advisory live-region information with implicit polite announcements and `alert` as assertive information that does not itself require focus. Orgmetra therefore uses `status` for ordinary progress/completion and `alert` for denial, stale evidence, and failure.
+- WAI-ARIA 1.2 defines `aria-busy` as the state indicating that an element is being modified and assistive technologies may wait to expose updates. Orgmetra sets it only while loading or recording one governed review.
+- WCAG 2.2 remains the current WCAG 2 Recommendation baseline. The UI preserves visible keyboard focus, a 44px minimum action target in the existing design-token system, actionable status copy, and no color-only state communication.
+- The current 2026 WCAG 2 working-group activity includes proposed editorial/non-normative updates; those proposals are not treated as a replacement normative specification in this PR.
+
+## APA 7 references

+World Wide Web Consortium. (2023). *Accessible Rich Internet Applications (WAI-ARIA) 1.2* (W3C Recommendation). https://www.w3.org/TR/wai-aria-1.2/

+
+## Product boundary
+
+The Storybook evidence correlates with the existing Figma `Orgmetra Baseline` Storybook Inventory node `1:64`. It is an active-PR design/test artifact and must not be presented as integrated protected-branch runtime until its dependency stack is merged and revalidated.

+# HR Workspace Job grade review state traceability
+
+## Truth boundary
+
+- Protected `develop` truth remains `develop@9e3e4847510e1e612b48474ba42b177b8ed824df` for this stack's base history; this child is **active-PR evidence only** until its dependencies are integrated.
+- Parent UI contract: PR #130 `feat/hr-workspace-protected-read-state@c92749cf5889a39de1ba8036742f96fd3451f459` owns shared protected-read accessibility semantics and Figma/Storybook correlation.
+- Job grade governance owner: PR #101 owns `JobGradeDesignReviewPacket`; this UI does not import that unmerged package and does not claim its review is protected-branch runtime.
+- Durable Job grade persistence is separately owned by dependency-first PR #109. This UI neither writes those tables nor treats persistence evidence as integrated.
+
+## Buyer-visible requirement → evidence
+
+| Requirement | Active-PR evidence | Safety meaning |
+| --- | --- | --- |
+| Load governed Job/Job Analysis/grade-design evidence before review | `loading` → `review` state model and Storybook stories | No cached or locally invented grade truth is treated as authoritative. |
+| Human review remains distinct from compensation/employment authority | `review` and `recorded` messages explicitly deny compensation/employment-decision authority | Reviewing a Job grade design does not authorize pay, promotion, assignment, selection, or another employment action. |
+| Prevent duplicate review submission while immutable evidence is being recorded | `recording` has `aria-busy=true` and a disabled action | One in-flight review recording is visible and duplicate activation is blocked in the interaction model. |
+| Stale upstream evidence fails closed | `stale` is an assertive alert with a reload action | A changed Job/Job Analysis/grade-design context must be reloaded before another review. |
+| Denied purpose/reviewer authority fails closed | `denied` is an assertive alert | The UI does not silently downgrade to a local or cached review path. |
+| Service failure provides a safe next action | `error` is an assertive alert and explicitly rejects cached review evidence | Customer-facing copy guides recovery without fabricating governance evidence. |
+| Storybook and Figma correlation remain discoverable | Every rendered state carries `data-figma-node-id="1:64"`; Storybook exposes eight named states | Reviewers can inspect loading, read-only, permission-denied, validation-error, error, and focus-related UI evidence. |
+| Owned interaction logic has exact coverage | `.github/workflows/hr-workspace-job-grade-review-state.yml` runs Node 24 test coverage at 100% lines/branches/functions | No missing owned branch is accepted as complete evidence. |
+
+## Data minimization
+
+The state model carries only constant governed copy and interaction semantics. It does **not** accept or serialize Person/candidate identity, employee names, contact data, compensation or salary values, ratings, assessment results, credentials/tokens, prompts, or model output.
+
+## Integration discipline
+
+Keep this PR Draft while #53 and #130 remain unintegrated. After those dependencies merge, retarget this child to fresh `develop`, reconcile intervening HR Workspace changes, and rerun all applicable browser/accessibility/Foundation/SAST/Security/Recovery and central exact-head gates. No predecessor check, review, or focused stack-local GREEN result transfers across that retarget.
