Gate 15-S Scale Summary

Caersyn Proof Study

System: Caersyn Trace

Milestone: Gate 15-S 1M

Status: Completed proof-of-operation demo

Suite mode: stage1

Customer used for proof run: caersyn

Result: PASS

Version: v0.2

Date: 07.07.26

Scale Result

Gate 15-S proved that Caersyn Trace can handle million-event workflow-shaped scale while preserving the core proof model.

The final Gate 15-S result was:

Gate 15-S 1M Bench: FULL PASS
submitted: 1,000,000
ledger_count: 1,000,000
event_ids_count: 1,000,000
observed_segment_count: 59
indexed_segment_count: 58
unsealed_observed_segment_count: 1
trace_count: 100,000
verifier_status: PASS
submit_seconds: 7,926.294
submit_rate: 126.16/sec
runtime: approximately 2 hours 12 minutes

The result supports the claim that:

1,000,000 workflow-shaped events were written into the Trace ledger, retained in hash-linked event order, matched by event-id index count, split across real segments and verified successfully after completion.

Breadth Result

The controlled source record also supports a multi-customer breadth result:

10 customer namespaces
10,000 events per customer
100,000 total events
aggregate_rate: 192.06/sec
all verifiers: PASS

The correct interpretation is:

A single active namespace sustained 126.16/sec at million-event depth on the tested hardware. Ten concurrent namespaces sustained 192.06/sec aggregate across 100,000 total events, with shared hardware capacity distributed across customers.

Throughput Statement

A conservative scale statement is:

On the tested local hardware, Caersyn Trace verified a million-event single-namespace run at 126.16 events per second, and verified a ten-namespace breadth run at 192.06 events per second aggregate. These are measured proof-run results, not a universal production guarantee.

What the Scale Result Preserves

The Gate 15-S scale result preserves the following claims:

append-only event history
hash-chain continuity
per-event deduplication
per-customer namespace isolation
segment rollover
checkpoint recovery state
workflow trace shape
external verification

What the Scale Result Does Not Claim

The scale result does not claim:

unbounded production throughput
all hardware configurations
all deployment conditions
all retention configurations
all concurrency profiles
third-party certification
legal admissibility
semantic truth of customer payloads

Source Record Boundary

The full Gate 15-S source record includes the engineering journey, patch history, bottleneck analysis, configuration details, profiling observations and optimisation decisions.

That full engineering diary is retained by Caersyn for controlled diligence.

This summary preserves the scale result without publishing unnecessary implementation-level detail.

Truth Boundary

Gate 15-S proves that Trace carried its proof model through million-event workflow-shaped scale on the tested run.

It does not prove external source truth or business correctness.

The boundary remains:

Trace proves the recorded ledger path and its verification result.
Source systems must support the truth of what they emit.
