+# Evidence Capsules Canonical Cutover
+
+## Purpose
+- Keep Decision Capsules owned by the live `Evidence` shell instead of splitting them across canonical routes, stale legacy bookmarks, and context-specific dead ends.
+- Finish the usable workflow, not just the references: list, detail, back-navigation, related-run handoff, and bookmark repair all need to work for operators.
+
+## Canonical Routes
+- `/evidence/capsules`
+- `/evidence/capsules/:capsuleId`
+
+## Alias Policy
+- Preserve `/evidence-packs`
+- Preserve `/evidence-packs/:capsuleId`
+- Redirect aliases into the canonical `/evidence/capsules*` subtree while preserving query params and fragments.
+
+## Shell Ownership
+- `Evidence` remains the only operator-facing owner of Decision Capsule browsing.
+- The capsule list uses Decision Capsule terminology consistently and opens detail pages inside the canonical Evidence shell.
+- Capsule detail exposes a back action that prefers the originating context and falls back to the canonical capsule list.
+
+## Cross-Shell Handoffs
+- `Ops > Operations > AI Runs` opens canonical capsule detail routes with a deterministic `returnTo` contract.
+- Capsule detail routes related AI-generated evidence back into `/ops/operations/ai-runs/:runId`.
+- Capsule detail routes release evidence into `/releases/runs/:runId/evidence`.
+- Related-run handoffs always preserve a valid return path back to the canonical capsule detail page.
+
+## Merge Notes From Dropped Surfaces
+- The stale `/evidence-packs*` surface was not preserved as a second owner route.
+- The useful behavior from the half-wired pack flow was merged into the canonical Evidence shell:
+  - bookmark-safe alias repair
+  - context-aware back navigation
+  - live owner-route jumps for AI and release contexts
+
+## Verification
+- Angular tests cover:
+  - canonical capsule route ownership
+  - legacy alias redirects
+  - list/detail navigation behavior
+  - capsule viewer `returnTo` and related-run handoffs
+- Playwright covers:
+  - a live AI Runs entry point into capsule detail and back
+  - a legacy `/evidence-packs/:capsuleId` bookmark that cuts over into the live release evidence workspace
