Amount: 0 CKB
Mode: fiber-rpc
Latency: 2ms
Failure stage: fiber_rpc_error
Sender: fiber-rpc-node
Receiver: fibt10001p6c...rdgdh9

ROUTE_NOT_FOUND

No viable route found

Route discovery could not find a path from sender to receiver under the current topology and policy filters.

Likely Causes

Receiver is not reachable from the sender's graph view
Channels are private or not announced to the route source
Policy filters excluded every candidate path

Suggested Fixes

Refresh topology data before retrying
Try an alternate route source
Open or announce a route that connects the sender and receiver

Replay-to-Fix Results

same_conditions

Original amount, route, peer state, fee limit, timeout, and asset unchanged

failed

The original failure reproduces under the same conditions, confirming the fingerprint is stable.

9ms

alternate_route

Selected alternate route excluding the failing condition

success

A route with different hops avoids the original failure point with slightly higher latency.

split_payment

Split payment into 0 CKB + 0 CKB

failed

Split payment does not resolve this failure fingerprint.

# FiberTracebox Report

## Trace Summary

- Trace ID: trace_d0c7e112-854f-46d6-81e4-382fef084536
- Payment status: replayed
- Amount: 0 CKB
- Sender: fiber-rpc-node
- Receiver: fibt10001p6c...rdgdh9
- Mode: fiber-rpc
- Latency: 2ms
- Failure time: 2ms
- Failure stage: fiber_rpc_error
- Failure fingerprint: ROUTE_NOT_FOUND


## Root Cause

Route discovery could not find a path from sender to receiver under the current topology and policy filters.

## Live Fiber Evidence

- Classified failure: ROUTE_NOT_FOUND
- Classification reason: FNN returned an unmapped payment failure; route discovery is the safest default.
- FNN error message: fetch failed

| channel id | state | enabled | local balance | remote balance | peer pubkey |
| --- | --- | --- | --- | --- | --- |
| Not captured | - | - | - | - | - |




## Evidence Source

- Trace source: fiber-rpc
- Replay mode: live evidence capture only; replay changes are not executed against FNN
- Live mutation: no
- RPC methods observed: not applicable
- Observed failure: not applicable
- Fiber RPC events come from configured FNN JSON-RPC calls.
- Dry-run mode requests route/payment checks without intentionally sending a new live payment.
- Replay-to-Fix remains analytical for live traces because alternate live attempts can move funds or mutate channels.

## Timeline

| ms | stage | severity | message |
| --- | --- | --- | --- |
| 0 | request_received | info | Live Fiber payment dry-run requested |
| 2 | fiber_rpc_error | error | fetch failed |

## Replay Results

| strategy | changed condition | result | latency ms | recommended |
| --- | --- | --- | --- | --- |
| same_conditions | Original amount, route, peer state, fee limit, timeout, and asset unchanged | failed | 9 | no |
| alternate_route | Selected alternate route excluding the failing condition | success | 14 | yes |
| split_payment | Split payment into 0 CKB + 0 CKB | failed | 54 | no |

## Smallest-Fix Recommendation

Smallest successful replay change: Selected alternate route excluding the failing condition



Confidence: high

## Suggested Next Actions

- Refresh topology data before retrying
- Try an alternate route source
- Open or announce a route that connects the sender and receiver
- Selected alternate route excluding the failing condition

## Mode Disclosure

Fiber RPC mode: live FNN evidence is captured from node, channel, graph, invoice, and payment RPC calls. Replay-to-Fix remains analytical for live traces because changing live route conditions can move funds or mutate channels.
