Design Workflows as Pipelines -- Trigger, Validate, Transform, Act, Notify

A consistent structural pattern across all workflows makes your automation system predictable. The five-stage pipeline pattern -- trigger, validate, transform, act, notify -- gives every workflow the same skeleton, which makes debugging faster and onboarding new team members easier.

Real-world example: A workflow that receives form submissions, validates the data, enriches it, creates a CRM record, and sends a confirmation.

Stage 1: TRIGGER
[Webhook: Form Submission]
    ↓
Stage 2: VALIDATE
[IF: required fields present] →── missing ──→ [Respond: 400 Bad Request]
[IF: email format valid]      →── invalid ──→ [Respond: 422 Invalid Email]
    ↓
Stage 3: TRANSFORM
[Edit Fields: Normalize names, set defaults]
[Edit Fields: Geocode address to lat/lng]
[Edit Fields: Calculate lead score]
    ↓
Stage 4: ACT
[HubSpot: Create/Update Contact]
[Postgres: Insert submission record]
    ↓
Stage 5: NOTIFY
[Slack: Alert sales team]
[Email: Send confirmation to submitter]
[Respond to Webhook: 200 OK]

Each stage has a clear responsibility:

```text
TRIGGER    → Where does the data come from?
             Webhook, schedule, trigger node, sub-workflow call.
             One trigger per workflow. Never mix trigger types.

VALIDATE   → Is the data acceptable?
             Required field checks, format validation, deduplication.
             Reject early with descriptive errors. Do not process bad data.

TRANSFORM  → Reshape the data for downstream consumption.
             Rename fields, compute derived values, enrich from other sources.
             All Edit Fields and Code nodes for data prep go here.

ACT        → Perform the business action.
             API calls, database writes, file creation.
             This is the "point of no return" — validate thoroughly before this stage.

NOTIFY     → Report the outcome.
             Success notifications, error alerts, audit log entries.
             Always notify on failure, optionally on success.

> Use Sticky Notes with consistent colors behind each stage group: blue for Trigger, yellow for Validate, green for Transform, red for Act, purple for Notify. This makes the pipeline stages visually obvious on the canvas.

The pipeline pattern is simple but its value compounds across dozens of workflows -- consistency becomes the most powerful debugging tool.
