Aberration correction provenance: Geocentric apparent place incorrectly includes site-dependent diurnal aberration · case 01

The adapter reports an incorrect geocentric apparent while other fields remain valid.

ROOT CAUSE

Geocentric apparent place incorrectly includes site-dependent diurnal aberration. Faulty expression: d['x']+d['a']+d['d']+d['g']

THE FAILURE

Geocentric apparent place incorrectly includes site-dependent diurnal aberration. Faulty expression: d['x']+d['a']+d['d']+d['g']

Unsuccessful approach: A partial convention repair still uses d['x']+d['a']

Case contract

Reduced astrometric place pipeline uses supplied additive corrections annual a, diurnal d, and deflection g. Catalog place x is uncorrected; geocentric apparent includes a+g; topocentric apparent additionally includes d. Inverse adapters must remove only corrections already included. No correction is physically calculated. Output fields are defined by: geocentric_apparent = d['x']+d['a']+d['g']; topocentric_apparent = d['x']+d['a']+d['g']+d['d']; annual_only_once = d['x'] if d['annual_done'] else d['x']+d['a']; diurnal_only_once = d['x'] if d['diurnal_done'] else d['x']+d['d']; catalog_from_geocentric = d['x']-d['a']-d['g']; geocentric_from_topocentric = d['x']-d['d']

Why this case matters

Catalog, detector, sky-coordinate, and spectroscopy adapters must preserve the association between numeric coordinates and their declared reference conventions.

HELD IN THE MEMBER ARCHIVE

The verified repair and its recorded checks are member-only.

This mechanism has 6 recorded checks per implementation. The open-access tier publishes the failure and the unsuccessful fix; the repaired source that passes every check, and the observations that prove it, are available to members.

Every case sharing this mechanism uses the same contract and the same repair, so this one record is held back for all of them.

Member access is invitation-based. Sign in with your invited account to inspect the repair.

Verification & scope

Explicitly stipulated finite algebraic adapter; no standards conformance, physical accuracy, or production-library claim. Inputs are the documented finite valid model domain. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.

Observations recorded using Python 3.12.14 at 2026-09-29T14:45:58.981929+00:00.
