+title: feat: Sync GUI zip bridge doc from source repo
+type: feat
+status: complete
+date: 2026-05-29
+origin: /lfg — plan 013/019 planned sync-workspace-bridge.sh; bridge doc now versioned in git
+---
+
+# feat: Sync GUI zip bridge doc from source repo
+
+## Summary
+
+Add `scripts/sync-gui-bridge-doc.sh` to copy `docs/gui-zip-recurring-scrape-bridge.md` into the sibling GUI zip folder as `RECURRING-SCRAPE.md`, with a smoke test using a temp destination.
+
+## Requirements
+
+| ID | Requirement |
+|----|-------------|
+| R1 | `sync-gui-bridge-doc.sh` copies bridge doc to configurable dest (default `../DiscordChatExporter.linux-x64/RECURRING-SCRAPE.md`) |
+| R2 | `--dry-run` prints source and destination |
+| R3 | `sync-gui-bridge-doc-smoke.sh` verifies copy into temp dir |
+| R4 | Operator checklist and gui bridge doc mention the sync script |
+| R5 | `run-all-smokes.sh` passes |
+
+## Verification
+
+- `./scripts/tests/sync-gui-bridge-doc-smoke.sh`
+- `DCE_MIN_FREE_MB=0 ./scripts/run-all-smokes.sh`
