+v1.4 milestone PAUSED. Phase 16 code was built and pushed, but UAT revealed that the Unraid GraphQL API on the user's server (Unraid 7.2.x) only has `start` and `stop` Docker mutations. The `updateContainer`, `updateContainers`, and `updateAllContainers` mutations exist in the Unraid API source code (GitHub commit 277ac42046) but only ship in Unraid 7.3+ which has not been released yet.
+
+v1.3 workflows have been restored to n8n and are running in production. The v1.4 work is preserved on branch `gsd/v1.0-unraid-api-native`.

+- Phase 15 (Infrastructure Foundation): 2/2 plans complete — Container ID Registry, Token Encoder/Decoder, GraphQL Normalizer, Error Handler
+- Phase 16 Plan 01: Container Status migration (n8n-status.json) — WORKING
+- Phase 16 Plan 02: Container Actions migration (n8n-actions.json) — WORKING (start/stop/restart)
+- Phase 16 Plan 03: Container Update migration (n8n-update.json) — BLOCKED (updateContainer mutation doesn't exist on 7.2.x)
+- Phase 16 Plan 04: Batch UI migration (n8n-batch-ui.json) — WORKING
+- Phase 16 Plan 05: Main workflow routing migration (n8n-workflow.json) — PARTIALLY WORKING (queries work, batch update mutation doesn't exist)
+- Phase 16 Plan 06: Gap closure (text command paths) — WORKING but had paired item bugs (fixed in debug)
+- UAT: 6/9 tests passed, 3 blocked on missing updateContainer mutation
+- Debug fixes committed: batch cancel wiring, text command paired item fix (.first().json), batch confirmation HTTP node
+- v1.3 workflows restored to n8n (all 8 workflows, HTTP 200)
+- STATE.md and ROADMAP.md updated to reflect pause
+</completed_work>
+
+<remaining_work>
+
+- Wait for Unraid 7.3 release (ships updateContainer, updateContainers, updateAllContainers mutations)
+- Re-run `/gsd:verify-work 16` to validate update operations work with 7.3
+- Fix any remaining issues from UAT re-test
+- Phase 17 (Cleanup): Remove docker-socket-proxy artifacts, container logs feature
+- Phase 18 (Documentation): Update docs for Unraid API-native architecture
+</remaining_work>
+
+<decisions_made>
+
+- PAUSE v1.4 rather than maintain hybrid Docker proxy + GraphQL architecture
+- ROLLBACK to v1.3 workflows on n8n for stable production use
+- v1.4 work preserved on branch (mutation signatures match what 7.3 will ship)
+- The `DOCKER:UPDATE_ANY` API key permission exists because permission system was defined before mutations shipped
+- Container update internally calls legacy Bash script (`/usr/local/emhttp/plugins/dynamix.docker.manager/scripts/update_container`)
+</decisions_made>
+
+<blockers>
+- Unraid 7.3 not released — `updateContainer` mutation unavailable on current server (7.2.x)
+- No workaround that maintains the "fully Unraid API native" architecture goal
+</blockers>
+
+<context>
+The entire v1.4 milestone was about replacing Docker socket proxy with Unraid's GraphQL API. Status queries and start/stop/restart all migrated successfully and passed UAT. But container updates (single, batch, update-all) require a mutation that only exists in Unraid 7.3+. The user decided to pause rather than maintain a hybrid architecture. When Unraid 7.3 ships, the existing Phase 16 code should work as-is since the mutation signatures in our code match what the API source defines.
+
+UAT also uncovered 3 bugs that were diagnosed and fixed by parallel debug agents:
+1. Batch cancel button: Route Callback output 20 was wired to empty array
+2. Text commands: Paired item breakage after GraphQL chain expansion (.item.json → .first().json)
+3. Batch confirmation buttons: Telegram node double-serialized reply_markup (converted to HTTP Request)
+
+These fixes are committed on the branch and will be ready when v1.4 resumes.

+<next_action>
+When Unraid 7.3 releases:
+1. Check `__type(name: "DockerMutations")` introspection to confirm updateContainer is available
+2. Switch to branch `gsd/v1.0-unraid-api-native`
+3. Push v1.4 workflows to n8n
+4. Run `/gsd:verify-work 16` — the 3 previously-blocked tests should now pass
+5. Continue to Phase 17 (Cleanup) and Phase 18 (Documentation)
