ALEPH
ALEPH-1 ยท engineering history

The road from components
to a continuing loop.

A repository-grounded timeline of the major verified engineering transitions visible in the current ALEPH codebase and audit history.

AUDIT

30-step authoritative implementation audit

The repository audit recorded 30/30 implementation surfaces and 30/30 unit verification, while clearly separating integration, authoritative execution and scientific demonstration. At that audit point: 10/30 integration verified, 9/30 end-to-end executed, 3/30 authoritative, 0/30 scientifically demonstrated.

HARDENING

Step-27 V3 release boundary

The Step-27 V3 status documented a release-native executable, fail-closed artifact verification, direct Lean release worker and engineering checks โ€” while explicitly leaving some mutation/reproducibility controls unfinished and refusing to claim science from the path.

ORGANISM SPINE

Durable event replay and organism coherence

The repo moved beyond isolated modules into a durable organism event spine: runtime, planner and scientific/recovery events were connected, replay became durable, and protected projections gained explicit transaction boundaries.

LEVEL-3

Scientific episode โ†’ prediction โ†’ execution

Level-3 commits connected typed predictions, scientific episodes, epistemic frontier evaluation, trusted result ingress, real execution, scientific experiment specification and admissibility. The system started forming a real closed experimental pipeline rather than a collection of standalone science modules.

LEVEL-3

Formal experiment IR and autonomous action chain

Formal experiment semantic IR, goal/CGE lowering, canonical formal artifact materialization and grounded realization were followed by execution-plan commitment, dispatch, observation capture, prediction evaluation, epistemic consequence bridges, frontier-aware planning and action authorization.

CURRENT BREAKTHROUGH

Level-3 closed autonomous loop proven

The latest repository commit adds an immutable, content-addressed proof over the full causal cycle:

committed state โ†’ planner observation โ†’ decision โ†’ commitment โ†’ authorization โ†’ one action โ†’ committed result โ†’ next pulse

The proof is explicitly bounded: it does not claim AGI, scientific omnipotence or unbounded self-improvement. That boundary is part of the achievement.

ALEPH-1 completion methodology

13% is an engineering index, not a hype number.

The repository does not contain a canonical full-vision completion field. The figure used across this site is therefore a weighted realization index constructed from the vision pillars in the master documentation and the current repository state.

Weighted realization indexโ‰ˆ 13%Conservative because the score discounts implementation-only surfaces and gives full-weight to integration, authority and demonstrated behavior.
