   4. The touched modules' READMEs and `docs/` pages are updated. The new code has unit tests, delivered in the phase's last plan.

 - [Phase 19.3]: 19.3-03: S3 driver opt-in via summer.yaml build.tags summercms_s3 (attach.S3BuildTag); untagged binaries refuse s3:// at boot naming the tag
 - [Phase 19.3]: 19.3-03: attach.DiskExtension derives the stored extension from the sniffed type (fixed table, script-capable client extensions become txt/bin); file_name keeps the client name
 - [Phase 19.3]: 19.3-03: storage.uploads.public_url applies to every attach URL; start-up line and docs require a public-files-only bucket
+- [Phase 19.3]: Site-cache purge is a cooler service (site_cache.purge_url, site_cache.purge_token); failures never fail a save
+- [Phase 19.3]: pact.ReorderAfterSave runs inside cabana's reorder transaction; reorderPost uses lagoon.Transaction so AfterCommit fires
+- [Phase 19.3]: Journal golem15.journal.site_cache.* kept as deprecated aliases for one release; framework keys win
+- [Phase 19.3]: 19.3-04 Task 4 reply push-all: plugins, layers, summercms master pushed; layer tags vue-faq/menu v0.2.0, vue-journal v0.4.0; no framework tag
