# WORKFLOW SCORECARD: Module A1 — Lead Enrich Pipeline
|
|
|
|
**Audited:** 2026/03/28
|
|
**Workflows:** Lead Enrich Core (`XUdpzb0QhHdwL3hi`), Lead Actions Example (`xrvKeRGJ297kWSno`)
|
|
**Mode:** Full audit (all 5 passes)
|
|
**Instance:** https://n8n.corbel.consulting
|
|
**TEST_MODE:** true (simulator path exercised)
|
|
|

|
## Pass 1: Silent Failure Scan
|
|
|
|
| Check | Lead Enrich Core | Lead Actions Example |
|
|
|---|---|---|
|
|
| HTTP Request `continueOnFail` | PASS | PASS |
|
|
| All branches reach response node | PASS | N/A (sub-workflow) |
|
|
| No silent error swallowing | PASS (note below) | PASS |
|
|
| No dead-end branches | PASS | PASS |
|
|
| Sub-workflow IDs valid | PASS (`xrvKeRGJ297kWSno` active) | N/A |
|
|
| Unique node names | PASS (12/12) | PASS (8/8) |
|
|
| Unique node positions | PASS (12/12) | PASS (8/8) |
|
|
| Webhook response mode consistent | PASS | N/A |
|
|
| No placeholder credentials | PASS | PASS |
|
|
|
|
**Note:** Enrichment Mapper has a try/catch on `$('Test Mode Check')` reference that falls back to `{}`. This is a deliberate fallback for lead data retrieval, not error swallowing. The primary path (`response.lead`) works correctly. Fallback would only trigger if the node reference mechanism itself fails.

|
|
|
**Silent failures found: 0**

## Pass 2: Entropy Scan (DOWNTIME)
|
|
|
|
| # | Waste Type | Finding | Severity |
|
|
|---|---|---|---|
|
|
| E1 | ~~Overproduction~~ | ~~Sheets Audit Log~~ → **FIXED:** Renamed to "Audit Log Formatter". Documented as a formatter stub in README. Buyers connect their own sink. | ~~HIGH~~ → RESOLVED |
|
|
| E2 | Waiting | No rate-limit throttling when `credits_low: true`. Header is read and flagged but no back-off action taken. | MEDIUM |
|
|
| E3 | ~~Inventory~~ | ~~Duplicate inactive workflow~~ → **FIXED:** `r54Zo0y04FfokkEN` deleted from instance. | ~~MEDIUM~~ → RESOLVED |
|
|
| E4 | Overproduction | `lead.raw_payload` captures full webhook input including headers. Not consumed downstream. Useful for debugging but adds payload size. | LOW |
|
|
| E5 | Non-Utilised Talent | Input Mapper (Set) + Clean & Validate (Code) could be combined. Kept separate for UI readability. | LOW |
|
|
|
|
**HIGH: 0 (1 resolved) | MEDIUM: 1 (1 resolved) | LOW: 2**

## Pass 3: Eval Harness
|
|
|
|
| # | Scenario | Input | Expected HTTP | Expected Grade | Actual HTTP | Actual Grade | Lead Present | Pass |
|
|
|---|---|---|---|---|---|---|---|---|
|
|
| 1 | Happy path | `full@test.com` | 200 | Full Profile | 200 | Full Profile (13 fields) | Yes | PASS |
|
|
| 2 | Partial data | `partial@test.com` | 200 | Partial Profile | 200 | Partial Profile (8 fields) | Yes | PASS |
|
|
| 3 | No org data | `limited@test.com` | 200 | Limited | 200 | Limited (6 fields) | Yes | PASS |
|
|
| 4 | No match | `nomatch@test.com` | 200 | Limited | 200 | Limited (0 fields, credits=0) | Yes | PASS |
|
|
| 5 | Rate limit | `error@test.com` | 200 | Limited (error) | 200 | Limited (error=true, credits_low=true) | Yes | PASS |
|
|
| 6 | Missing email | (no email field) | 422 | Error | 422 | "Email is missing or empty" | Yes | PASS |
|
|
| 7 | Bad email format | `not-an-email` | 422 | Error | 422 | "Invalid email format: not-an-email" | Yes | PASS |
|
|
|
|
**Eval harness: 7/7 passed (100%)**
|
|
|
|
**Key validation:** Lead data survives through all nodes to the response in every path. The lead data loss bug (session 23) is confirmed fixed.

## Pass 4: Throughput Test
|
|
|
|
### Smoke Tier (10 concurrent)
|

|
| Metric | Value |
|
|
|---|---|
|
|
| Requests | 10 |
|
|
| All 200s | Yes |
|
|
| Wall time | 510ms |
|
|
| Median | 328ms |
|
|
| p95 | 361ms |
|
|
| Max | 361ms |
|
|
| Min | 232ms |
|
|
| Throughput | ~20 req/s |
|
|
|
|
**p95 (361ms) < 2,000ms threshold: PASS**

## Resolved Fixes
|
|
|
|
### E1 — Sheets Audit Log renamed to Audit Log Formatter [RESOLVED]
|
|
|
|
**Was:** "Sheets Audit Log" Set node with no downstream writer — data prepared then dropped.
|
|
**Fix applied:** Renamed to "Audit Log Formatter". README updated to document it as a formatter stub. Buyers connect their own sink (Google Sheets, Supabase, etc.). Updated on live instance and local JSON.
|
|
|
|
### Execute Workflow Trigger missing inputSource [BONUS FIX]
|
|
|
|
**Was:** `parameters: {}` on the Execute Workflow Trigger v1.1 — the n8n API refused PUT updates because `inputSource` is required.
|
|
**Fix applied:** Added `inputSource: "passthrough"` to both live instance and local JSON.
|
|
|
|
### E3 — Duplicate inactive workflow deleted [RESOLVED]
|
|
|
|
**Was:** `r54Zo0y04FfokkEN` — old inactive copy of Lead Enrich Core on the instance.
|
|
**Fix applied:** Deleted from instance via API.
|
|

|
|
## Items for Review (non-blocking)
|
|
|
|
### E2 — No rate-limit back-off [MEDIUM]
|
|
|
|
The `credits_low` flag is set when Apollo rate limit drops below 50, but nothing acts on it. In production with high volume, this could lead to 429 errors piling up. Consider adding an IF node after the mapper that pauses or queues when credits are low.
|
|

|
## Notes
|
|
|
|
- Audit ran against TEST_MODE (simulator path). Live Apollo path untested due to free plan blocking `people/match`. The simulator exercises the same Enrichment Mapper & Grader code, so the parsing/grading logic is validated.
|
|
- Lead Actions Example was not executed end-to-end (HubSpot, Slack, SMTP credentials not verified). The audit covers structural integrity and data flow only.
|
|
- Previous test results from session 23 (in README.md) are consistent with this audit.
