Hosted case study with public verification
Revenue Flow Guard
A hosted technical case study showing how a revenue-critical SaaS journey can be tested before delivery.
The offer
A focused release-confidence sprint for one revenue-critical SaaS journey: map the failure modes, add risk-driven Playwright checks, and leave a maintainable handoff. This describes the offer and deliverables, not a promised business outcome.
The deliverable
A hosted case study, a public verification method, signed sanitized evidence, and a handoff conversation for adapting the approach to your flow. The complete implementation remains private.
01 — Risks
Six controlled risks
The study names the failures the control logic exists to surface, without promising to prevent them.
- 01Duplicate processing can count or charge the same flow twice.
- 02A missed webhook can drop an update while the system still reports success.
- 03Retries without an idempotency boundary can diverge the state.
- 04Replayed or unsigned webhook traffic can alter records.
- 05Ambiguous money-movement claims without a traceable source.
- 06Silent degradation where a failure looks like a successful step.
02 — Proof
Five proof steps
A reviewer can reproduce each step against the control logic in an isolated sandbox.
- 01Reproduce the revenue event against the control logic in an isolated sandbox.
- 02Run the deterministic idempotency and replay checks.
- 03Inspect the audit trail for each step.
- 04Force a controlled failure and confirm it surfaces instead of succeeding.
- 05Confirm every write remains behind an explicit human decision.
03 — Boundary
Human boundary
A person owns every access grant and any real money movement. The study documents the control logic and its boundary; it does not move funds on its own and it does not claim client results.
04 — Limits
Limitations
What this case study does not claim.
- The hosted case study is a synthetic demonstration, not customer or production data.
- Public evidence is sanitized and signed; it does not claim client results.
- The public repository exposes verification material only, not the implementation.
- Payment, account, and business APIs are not exposed publicly.
- Suitability and scope must be confirmed for each client journey.
