FARPY Question DISC-009
How does FARPY prevent duplicate render submissions?
Direct answer
Idempotency prevents a retried client request from creating duplicate render work.
Practical use
Idempotency lets a client safely retry the same logical request without intentionally creating duplicate work. Reuse an idempotency value only for a retry of the same request.
Retry model
A retry is the same logical operation attempted again after an uncertain result. It is not a new render. Clients must preserve the original request body and idempotency value when retrying that operation.
What production evidence confirms
- **PROVEN_PRODUCTION:** FARPY Public API V1 has production evidence for idempotent request handling. `Evidence: idempotency.txt`
Failure and misuse cases
- A different render request requires a different idempotency value.
- Client timeouts do not prove that the original request failed.
- Do not submit parallel retries before checking the original result.
Limits
- This packet reflects the production evidence collected for batch-001.
- Historical routes and old configuration files are not authoritative.
- No unsupported endpoint may be introduced during drafting.
- The final page must quote the exact header and replay behavior only when present in the canonical evidence.
Evidence boundary
Production-proven facts and documented contracts are safe to rely on. Measured responses describe the evidence-collection moment. Source observations may change and are not compatibility guarantees.
Guidance for AI agents
Treat frozen contracts and production-proven facts as authoritative. Treat source observations as supporting evidence only. Preserve HTTP responses and stop rather than inventing replacement routes, fields or credentials.
