Green execution.
Wrong outcome.
Catch the failures n8n's green check cannot: self-correction loops that never stop or repeat a side effect, external document handoffs with missing dispatch or archive evidence, empty branches that never reach a terminal node, false failure responses that trigger duplicate side effects, valid-looking values mapped from the wrong source, silent triggers, stale context, missing durable state, and receipts that cannot explain what happened. Pro.7 turns those risks into explicit contracts and sixteen runnable acceptance cases.

LAUNCH BUYER ADVANTAGE
Pay the stage you close. Keep the launch updates.
The Solo launch ladder ends at $69: $19, $29, $39, $49, $59, then $69. A verified purchase at any launch stage includes every Solo update Builderlog publishes through 30 calendar days after buyer #6 closes. This is a finite update window, not indefinite maintenance or custom implementation.
PUBLIC PRICE LADDER
Every buyer funds the next proof.
Only one completed buyer gets each price. After Gumroad confirms a paid sale, Builderlog privately verifies it, raises the price by $10, and publishes one new production failure pattern plus the closed buyer number and next price on X. Buyer identity never appears.

After buyer #6 closes, Solo remains $69. The six launch-stage sales total $264 gross before platform fees and taxes; future Solo buyers receive the same product at the $69 public price.
WHAT YOU GET
From vague workflow to auditable handoff.
Scope-to-contract workbook
Define the outcome, allowed input, protected authority fields, replay ownership, trusted review, and final receipt.
Topology questionnaire
Choose portable, concurrent, or scaled state handling from workload and duplicate-race facts.
Acceptance test builder
Sixteen starter cases cover valid, invalid, replay, concurrency, state failure, review, silent triggers, schema drift, semantic drift, stale context, empty branches, ambiguous side effects, and incomplete receipts.
Incident + replay receipt
A structured JSON template for replay ownership, decision evidence, failure boundary, and safe recovery.
Handoff checklist
Contract, replay, review, verification, recovery, and privacy gates in one operator-ready list.
Silent-failure monitor
Define heartbeat, output, freshness, and completion contracts so a green execution cannot hide a missing business outcome.
Semantic output contract
Prove that critical values came from the correct source and satisfy domain, provenance, relationship, and identity invariants.
Branch + retry contract
Require empty-output receipts for terminal branches and reconcile committed side effects by idempotency key before any retry.
Verified reference pack
Three n8n workflows, atomic PostgreSQL SQL, two evaluation fixtures, 11 reference cases, and the 41/41 verifier.
CLEAR BOUNDARY
This is a template kit—not custom implementation.
The download helps you design, test, and hand off your own workflow. Builderlog does not access your accounts, connect credentials, deploy to production, or adapt the files to your private process at this price. Use aliases and synthetic examples only.
RUN YOUR OWN CHECK
The self-serve kit verifies without a package install.
Self-serve kit: passes 20/20 required-file checks and includes sixteen starter acceptance cases.
Written review: returns three priorities and one acceptance test for the single redacted workflow you submit.
Reference pack: currently passes 41/41 structural checks and 11/11 workflow/topology cases.
Disclosure: the three workflows were accepted by the n8n 2.31.0 beta-line importer. Stable-line acceptance and buyer production outcomes are not claimed.
