Summary

• replace the Voice Memo placeholder with an activatable POST /webhook/ods-voice-memo workflow
• validate multipart audio, content type, title, and optional model selection before inference
• discover the model IDs actually served by bundled Whisper instead of hard-coding a backend-specific default
• preserve binary data across model discovery, send a bounded multipart transcription request, and normalize success/error JSON

Why this matters

Voice Memo is already advertised in the workflow catalog with a one-minute setup time, but enabling it previously imported only a manual trigger and sticky note. Users got no webhook and no transcription path. This PR makes the catalog action deliver the runnable local feature it promises.

The invariant is: only multipart field data reaches Whisper, its model must exist in Whisper's live model catalog, binary data survives the discovery branch, and audio/transcript content is not persisted by the workflow.

Overlap check

Searched open and closed upstream PR titles/bodies for n8n voice memo Whisper workflow, reviewed the latest 1,000 open PRs and changed production files, and inspected voice-memo.json history. No PR changes this workflow or implements this scope; its upstream history only contains the repository rename. The earlier runnable Daily Digest, Image Generation, and Email-to-Task PRs operate on different catalog entries and files.

Multipart field configuration was checked against n8n's official HTTP Request node implementation: https://github.com/n8n-io/n8n/blob/master/packages/nodes-base/nodes/HttpRequest/V3/HttpRequestV3.node.ts

Test plan

• python -m pytest test_n8n_voice_memo_template.py test_workflows.py -q ? 48 passed
  • authenticated public enable imports the exact shipped graph and activates its returned n8n ID
  • webhook, branch, merge-input, binary-field, model-discovery, timeout, sanitizer, and terminal error contracts
  • all existing workflow management tests remain green
• docker run --rm ... n8nio/n8n:2.6.4 import:workflow --input=/workflows/voice-memo.json ? successfully imported 1 workflow using the exact image ODS ships
• python -m json.tool ods/config/n8n/voice-memo.json
• python -m compileall -q .../test_n8n_voice_memo_template.py
• git diff --check

Design and operational notes

• The webhook relies on ODS's existing n8n exposure policy and Whisper service dependency; no external credential is added.
• Model discovery makes CPU, NVIDIA, AMD, and Apple-selected Whisper deployments use the model they actually expose.
• HTTP failures continue to controlled branches so callers receive explicit 503/502 JSON rather than an empty successful transcript.
• Exact-version CLI import proves n8n 2.6.4 accepts the graph. A live audio transcription was not claimed because no running Whisper model/audio fixture was available for this validation.
• Rollback restores the catalog placeholder; no database migration or stored memo cleanup is required.

Batch compatibility

• Recommended merge/application order: feat(installer): add configuration-first TUI #3706 -> feat(test): support multi-service validation subsets #3707 -> feat(api): add conditional model-state reads #3708 -> feat(api): batch model route evidence queries #3709 -> feat(api): add GPU history query controls #3710 -> feat(dashboard): export GPU history as CSV #3711 -> feat(dashboard): focus GPU topology links #3712 -> feat(mobile): bootstrap remote ODS Talk portal #3713 -> feat(workflows): make voice memo runnable #3714 -> feat(workflows): make chat endpoint runnable #3715. The PRs have no runtime dependency; this order also covers the shared MODEL-SWITCHBOARD.md edits in feat(api): add conditional model-state reads #3708/feat(api): batch model route evidence queries #3709.
• Synthetic integration head: tang-vu/DreamServer commit 5e4e354 on integration/features-ten-20260904, built from upstream/main 6ff9b4f plus all ten PR heads.
• Combined validation: 12 BATS tests passed; 132 focused API/workflow pytest tests passed; 6 dashboard Vitest tests passed; ESLint and the 1,771-module Vite production build passed; make lint, installer integration (69 passed, 3 skipped), the 6-test ods-test contract, mobile dispatch smoke, and exact n8n 2.6.4 imports for both workflow templates passed. git diff --check is clean.
• Full-suite limitation: make test reaches tests/test-installer-noninteractive-sudo.sh and reports 3 passed / 2 failed when WSL runs as root. The same two assertions fail unchanged on the clean upstream base 6ff9b4f, so this is recorded as environment/baseline evidence rather than attributed to this batch. All required GitHub checks for the ten PR heads are green as of 2026-09-04.
