Detector cutout reference: Inclusive data section endpoint is confused with science width · case 01

The adapter reports an incorrect science last x while other fields remain valid.

ROOT CAUSE

Inclusive data section endpoint is confused with science width. Faulty expression: d['w']

THE FAILURE

Inclusive data section endpoint is confused with science width. Faulty expression: d['w']

Unsuccessful approach: A partial convention repair still uses d['hx']+d['w']-1

Case contract

A one-based FITS-like detector cutout has zero-based start sx,sy, explicit halo hx,hy, and unchanged plate scale. CRPIX belongs to the padded cutout; valid bounds exclude halo. Data section uses inclusive pixel endpoints. Output fields are defined by: crpix_x = d['rx']-d['sx']+d['hx']; crpix_y = d['ry']-d['sy']+d['hy']; science_first_x = d['hx']+1; science_last_x = d['hx']+d['w']; parent_first_y = d['sy']+1; parent_last_y = d['sy']+d['h']

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 2026-09-29T14:45:52.356095+00:00.
