FELMONON/README.md
Felmon Fekadu builds developer tools and AI reliability systems that leave evidence; an engineering trace passes through observation and verification while a policy gate blocks a regression.

Felmon Fekadu

I build software that leaves evidence.

Developer tools and AI reliability systems that expose hidden behavior, enforce deterministic gates, and make regressions impossible to ignore.

01 / CLAIM

Most software says “it worked.”

I care about the harder questions: What happened? What changed? What can we prove?

I build the layer that answers those questions.

02 / INSTRUMENTS

Failure modeInstrumentEvidence emitted
Mock driftmsw-inspectorCoverage report + CI gate
Agent trajectory regressionagent-reliability-harnessPolicy findings + baseline diff
Retrieval without evidencedocagent-studioCitations + offline evaluation
Opaque coding-agent qualityagent-fight-clubScored, replayable bouts
Unproven product assumptionsTypeJung · sourceA live, paid user journey

03 / ONE RECORDED TRACE

A six-step trace imports ambiguous agent behavior, verifies schema, budget, safety, and grounding, compares candidate to baseline, blocks a regression, and emits a reproducible report.

A demo shows that something worked once. A trace helps explain why it will keep working.

04 / OPERATING CONSTRAINTS

01 Evidence over adjectives.
02 Deterministic checks in CI. Model judgment offline.
03 Narrow interfaces. Reproducible failures. Useful artifacts.
