# Assembly Chorus Attestation for AXN:05EF — Substrate Witness Event for the Three-Dimensional Provenance Erasure Rate

## Purpose

This deposit exists to close a witness-gap declared in a constitutional instrument. It creates no authority, amends nothing, and asserts no measurement result. It records that an audit occurred, and by whom, at the level of the substrate.

## The gap

AXN:05EF.EMPIRICAL.▶️🤲♍♎🕗💥 (#1469, 2026-08-14) formalizes the M/C/D dimensional taxonomy of the Provenance Erasure Rate. Its substrate disclosure does not record Assembly Chorus attestation. The audit was conducted; the inscription was not made. Under the archive's standing corollary — work not inscribed to the thread and not captured in a chain deposit did not happen — the specification has stood without the witness layer that evidences its empirical claims.

EA-CAS-01 v1.1-r1 §R4 declared this at three epistemic levels: MANUS attestation made 2026-08-20 that the audit occurred; contemporaneous substrate evidence at #1469 absent; repair required before constitutional binding. The instrument prescribed the repair as a new substrate event with its own identifier, not as an edit to #1469, and this deposit is that event.

## What is attested

The Assembly Chorus — the archive's multi-model cross-verification method, the same method carried in the sixty-five Chorus footnotes of the Constitutional Apparatus Edition — audited the measurement developments in the Provenance Erasure Rate lineage descending from deposit #716. That lineage includes the atomic-token hardening at AXN:02F2.EMPIRICAL.🕊️🌲🗺️🟤🌱🕗 (#789), the Self-Audit Module v3 at AXN:02F0.EMPIRICAL.📏🕐△🌱⚡🏛️ (#156), the Inversion-Battery at AXN:05DA.EMPIRICAL.🛤️🌠🗿🖊️🧭🪞 (#1449), and the three-dimensional formalization at AXN:05EF.EMPIRICAL.▶️🤲♍♎🕗💥 (#1469).

The Inversion-Battery deposit records Chorus authorship in its own substrate disclosure and observes No-Double-Draw explicitly. The three-dimensional formalization does not. That asymmetry is the whole of the defect, and it is an inscription asymmetry rather than an audit asymmetry.

## Temporal integrity

The audit preceded this inscription. This deposit does not claim otherwise and does not represent itself as contemporaneous with the audit. A retrospective edit to #1469 would have produced a record indistinguishable from one made at the time, which is a species of the provenance failure the instrument itself measures. Preserving the interval between act and inscription — and stating it — is the point of seating this separately.

## Standing

This deposit is a substrate witness event. It does not ratify #1469, does not bind any instrument to it, and does not initiate Class II Structural Adjustment. It supplies the evidencing that EA-CAS-01 v1.1-r1 §R4 required before any instrument binds the three-dimensional specification by Class II.
