+# feature/resource-tagging-v2
+
+## What's in this branch
+All 70 tutorial scripts with resource tagging (69 tagged, 1 SES has no taggable resources).
+
+Tags: Key=project,Value=doc-smith and Key=tutorial,Value={tutorial-id}
+
+## Sources
+- 29 from pipeline (tested end-to-end in Fargate)
+- 41 fixed locally (syntax-checked + 10 tested locally)
+
+## Local test results (10 light tutorials)
+- 7/10 pass: athena, iot-core, kvs, ecr, lambda, step-functions, mediaconnect
+- 2 pre-existing bugs (not tagging): cloudwatch-streams (zip), textract (sample doc)
+- 1 environment: config (shared bucket conflict)
+- 0 tagging-caused failures
+
+## Before publishing
+- [x] Rebase off feature/non-interactive
+- [x] Local test light tutorials (7/10 pass, 0 tagging bugs)
+- [ ] Test medium tutorials locally (VPC-creating, sequential)
+- [ ] Fix 032-cloudwatch-streams zip bug (pre-existing)
+- [ ] Fix 074-textract sample document (pre-existing)
+
+## After publishing
+- [ ] Run full suite in pipeline to verify
+- [ ] Test heavy tutorials that need special prereqs
