+# PR_26180_OWNER_019b-move-browser-shared-schemas-to-www Report
+
+## Executive Summary
+
+Moved the PR019a-audited active browser/runtime shared contract and tool schema files from root `src/shared/` into `www/src/shared/`.
+
+This preserves public browser route compatibility because the local/static web root serves `www/`, so URLs such as `/src/shared/schemas/tools/palette-browser.schema.json` still resolve to `www/src/shared/schemas/tools/palette-browser.schema.json`.
+
+No API/server-owned files, validation-only files, protected developer workspace files, UI pages, database files, or product behavior were moved.
+
+## Stack Context
+
+- Workstream: Repository Architecture Simplification
+- Previous dependency: `PR_26180_OWNER_019a-contracts-schemas-obsolescence-audit`
+- Base branch: `PR_26180_OWNER_019a-contracts-schemas-obsolescence-audit`
+- Source branch: `PR_26180_OWNER_019b-move-browser-shared-schemas-to-www`
+- Intended next dependency: remaining server/API and dev-owned `src/` retirement PRs
+
+## Source Of Truth
+
+Used `dev/reports/PR_26180_OWNER_019a-contracts-schemas-obsolescence-audit_audit.csv`.
+
+Only rows classified as `Active browser/runtime dependency` with recommendation `move to www/` were moved.
+

+- src/shared/schemas/tools/vector-map-editor.schema.json -> www/src/shared/schemas/tools/vector-map-editor.schema.json
+
+## Path Updates
+
+- Updated active tool/schema tests to read browser tool schemas from `www/src/shared/schemas/tools/`.
+- Updated `dev/scripts/validate-json-contracts.mjs` so tool schema validation indexes `www/src/shared/schemas/tools/` while still indexing remaining root `src/shared/schemas/` files.
+- Updated Project Instructions version/state/canonical structure/backlog to record the browser schema/contract ownership split.
+
+## Compatibility Decision
+
+Schema `$id` values and browser string identifiers remain in the public `src/shared/schemas/tools/...` form. This is intentional because the public browser URL shape remains `/src/shared/...` under the `www` web root.
+
+## Scope Guard
+
+- Runtime behavior changed: No
+- Product/UI pages changed: No
+- API/server files moved: No
+- Database files changed: No
+- Protected developer workspace moved: No

+## Notes
+
+`dev/tests/tools/ObjectVectorStudioV2DeleteCleanup.test.mjs` is not part of the active node test runner and still depends on a removed legacy Object Vector tool module path from before this PR. This PR updated only its schema file path for the moved browser schema; it did not expand into legacy test resurrection.
