+| 2026-03-07 | Wired active release, approval, promotion, workflow-editor, evidence, security, home, settings, search, and timeline entry points into the shared shell so mutable policy and VEX actions no longer depend on orphan routes. | FE |
+| 2026-03-07 | Verification passed: `npm test -- --watch=false --include ...` (10 targeted spec files, 94 tests), `npx playwright test tests/e2e/policy-decisioning-studio.spec.ts` (4/4), and `npm run build` (production build pass; existing size-budget warnings remain). | QA |

+# Policy Decisioning Studio UI
+
+## Module
+Web
+
+## Status
+VERIFIED
+
+## Description
+Shipped the canonical `Policy Decisioning Studio` shell at `/ops/policy` and made it the mutable owner for policy packs, governance, simulation, VEX, exceptions, release gates, and policy/VEX audit. Legacy `policy-studio`, `policy/*`, `admin/policy/*`, `admin/vex-hub/*`, and security VEX aliases now resolve into the same routed shell instead of leaving writable sibling products active.
+
+## Implementation Details
+- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/policy-decisioning/`
+- **Primary components**:
+  - `policy-decisioning-shell.component.ts`
+  - `policy-decisioning-overview-page.component.ts`
+  - `policy-pack-shell.component.ts`
+  - `policy-decisioning-vex-shell.component.ts`
+  - `policy-decisioning-gates-page.component.ts`
+  - `policy-decisioning-audit-shell.component.ts`
+- **Canonical routes**:
+  - `/ops/policy/overview`
+  - `/ops/policy/packs/*`
+  - `/ops/policy/governance/*`
+  - `/ops/policy/simulation/*`
+  - `/ops/policy/vex/*`
+  - `/ops/policy/gates/*`
+  - `/ops/policy/audit/*`
+- **Legacy aliases**:
+  - `/policy-studio/*`
+  - `/policy/*`
+  - `/admin/policy/*`
+  - `/admin/vex-hub/*`
+  - `/security/vex*`
+  - `/security/exceptions*`
+- **Release-context entry points**:
+  - approvals detail
+  - promotion request
+  - release detail
+  - workflow editor
+  - evidence detail
+
+## E2E Test Plan
+- **Setup**:
+  - [x] Log in with a user that has policy, VEX, exception, and release read scopes.
+  - [x] Seed pack dashboard data or route fixtures for `/api/policy/packs` and `/api/policy/packs/:packId/dashboard`.
+  - [x] Start the local UI harness on `https://127.0.0.1:4400`.
+- **Core verification**:
+  - [x] Verify `/ops/policy/overview` renders the canonical shell and primary tabs.
+  - [x] Verify a legacy pack bookmark lands inside pack-mode decisioning.
+  - [x] Verify a release-context gate URL renders context chips and return-to-source affordance.
+  - [x] Verify `/security/vex` redirects into the canonical VEX shell.
+- **Regression verification**:
+  - [x] Verify targeted Angular route and redirect specs cover the alias contract.
+  - [x] Verify workflow-editor and evidence-detail deep links open the shared shell.
+  - [x] Verify global search VEX normalization lands in the canonical shell.
+
+## Verification
+- Run:
+  - `npm test -- --watch=false --include src/tests/policy_decisioning/policy-decisioning-shell.component.spec.ts --include src/tests/policy_decisioning/policy-decisioning-routes.spec.ts --include src/tests/release_orchestrator/evidence-detail.behavior.spec.ts --include src/tests/release_orchestrator/visual-workflow-editor.behavior.spec.ts --include src/tests/security/security-overview-dashboard.behavior.spec.ts --include src/tests/global_search/search-route-matrix.spec.ts --include src/tests/navigation/legacy-redirects.spec.ts --include src/tests/routes/legacy-route-migration-framework.component.spec.ts --include src/tests/administration/administration-routes.spec.ts --include src/tests/security-risk/security-risk-routes.spec.ts`
+  - `npx playwright test tests/e2e/policy-decisioning-studio.spec.ts`
+  - `npm run build`
+- Tier 0 (source): pass
+- Tier 1 (build/tests): pass
+- Tier 2 (behavior): pass
+- Note: the production build still emits existing bundle-budget warnings outside this feature scope; the build itself completes successfully.

 # Policy Decisioning Studio
 
-## Recommendation
+## Status
-
+Shipped on 2026-03-07.
-Create one dynamic sub-product shell, not one giant page and not three separate sibling products.
 
+## Product Shape
 - Canonical mount: `/ops/policy`
-- Suggested user-facing title: `Decisioning Studio`
+- User-facing title: `Policy Decisioning Studio`
-- Suggested nav label for now: keep `Policy` to avoid unnecessary IA churn during rollout
+- Active primary tabs: `Overview`, `Packs`, `Governance`, `Simulation`, `VEX & Exceptions`, `Release Gates`, `Audit`
+- Supported modes: `global`, `pack`, `release-context`, plus non-owning `approval`, `workflow`, and `evidence` context chips
 
-This shell should unify the current policy workspace, policy governance, policy simulation, and the actionable parts of VEX conflict resolution into one product surface with deep-linkable tabs and a shared context model.
+This is now the canonical mutable owner for policy packs, governance controls, policy simulation, VEX resolution, exception handling, release-gate review, and policy/VEX audit.
 
-## Why This Is The Right Shape
+## Shipped Route Contract
-
-- Policy authoring, governance, simulation, VEX overrides, exceptions, and release gates are all parts of one decisioning workflow.
-- Release Orchestrator is a consumer of policy/VEX decisions, not a second owner of those UIs.
-- The current split creates duplicated mental models: packs live in one branch, governance in another, simulation in another, and VEX conflicts off to the side.
-- A single shell allows one shared context header for tenant, pack, environment, artifact digest, and release.
-- Deep-linkable child routes preserve auditability and operator workflows better than a modal-heavy or single-scroll design.
-
-## Product Modes
-
-The shell should support three modes without forking the UI into separate apps.
-
-### 1. Global Mode
-- Used by policy admins and security operators.
-- Focus: pack inventory, governance controls, simulations, trust/VEX posture, gate policy defaults.
-
-### 2. Pack Mode
-- Used when the user is working on a specific policy pack.
-- Focus: editing, YAML, rule builder, approvals, explain traces, simulation for one pack.
-
-### 3. Release Context Mode
-- Entered from Release Orchestrator deep links.
-- Context is pinned in the shell header: `releaseId`, `environment`, `artifactDigest`, `approvalId`, and effective policy bundle.
-- Focus: "why is this promotion blocked / allowed?" rather than general administration.
-
-## Recommended IA
-
-### Primary tabs
-- `Overview`
-  - decision board for active packs, pending approvals, open conflicts, shadow-mode readiness, and gate health
-- `Packs`
-  - policy pack inventory and pack-scoped workspace
-- `Governance`
-  - risk budgets, trust weights, staleness, sealed mode, profiles, validator, governance audit
-- `Simulation`
-  - shadow mode, console, coverage, effective policy, diff, merge preview, history, batch evaluation
-- `VEX & Exceptions`
-  - VEX conflicts, consensus review, overrides, exception queue, exception detail, rationale capture
-- `Release Gates`
-  - gate catalog, environment-specific gate policy, release-context gate evaluation, promotion readiness
-- `Audit`
-  - immutable policy/VEX decision history, evidence pointers, exports, explain traces
-
-### Secondary navigation
-- Use child tabs inside the active primary tab.
-- Use a contextual right rail for evidence, explain traces, or release summary.
-- Never hide critical release-decision screens behind modal-only flows.
-
-## Route Contract
-
-Keep `/ops/policy` as the canonical root and move the product to a single route tree.

-- Page-owned context and self-serve guidance
-- Stable deep links for every tab and subview
-- Scope-aware tabs that hide or disable only what the operator cannot act on
-- Shared evidence and explain cards reused across policy, VEX, and release contexts
-- Deterministic loading order and route aliases so legacy bookmarks remain functional during rollout
 
-## Non-Goals
+## Verification Evidence
-
+- feature verification note: `docs/features/checked/web/policy-decisioning-studio-ui.md`
-- Do not move all security exploration into this shell; read-only security analytics can remain elsewhere if they deep-link into the same canonical decisioning routes when action is required.
+- targeted Angular tests: `94` passing assertions across route, shell, redirect, workflow, evidence, and search coverage
-- Do not let Release Orchestrator fork its own policy editor or VEX conflict UI.
+- Playwright: `4/4` passing scenarios for global mode, pack mode, release-context mode, and security VEX alias redirect
-- Do not collapse everything into one scroll page; operators need stable, bookmarkable subviews.
+- production build: pass, with existing unrelated bundle-budget warnings
