Observation: Google AI Overview, 2026-10-14 · the capture
Description: BOTH NAMES HELD, THE OPERATOR NAMED, CASE 001 MOVED TO ZENODO: at 'persistent identifier erosion observatory' the Overview gives the instrument under both names ('The Platform Erosion Observatory (also known as the PID Erosion Observatory)'), its premise ('PIDs are not permanent strings, but rather maintained relations'), its measures (custody separation, tombstone compliance, 'the shape of absence'), its roadmap, and names its operator: 'a broader, sovereign alternative tracking architecture spearheaded by researcher Lee Sharks'. It places the Severance Registry / Resolution Index and the Capture Registry beside it, the latter in the archive's own words (#1067: 'the Capture Registry measures representation and correction asymmetry'). One figure moves: Case 001, the 14,284 DataCite DOIs of the Firenze client crui.unifi (#1408), becomes 'a specific cohort of over 14,000 DOIs' tracked for …
Reading: Checked 2026-10-14: 'Rate measures attribution separation; the Platform Erosion Observatory measures custody separation; the Capture Registry measures representation and correction asymmetry' is #1067's; 'a 14,284-DOI control cohort' and 'the shape of absence' are the observatory's own description (spxi.dev, method 0.15); PEO Case 001 is #1408, 'T0 Enumeration of the Firenze crui.unifi Corpus (14,284 DOIs)', a DataCite client collapse (14,283 → 0, 13–20 July 2026), not a Zenodo cohort; 1,838 severed identifiers through the Resolution Index is #1068's card snippet.
Analysis: At the spelled-out name the Overview holds the instrument whole, both names as one, with its operator named and the archive's own division of labour among its instruments; the error is at one figure, a DataCite case carried into the Zenodo census. Against the 'what is' Overview the same day, the names that one split are here joined. Seated 2026-10-14 from the operator's message of 15:02 EDT, on the attestation in the same message ('signed out incognito both').
Match: BROAD MATCH — BOTH NAMES HELD, THE OPERATOR NAMED, CASE 001 MOVED TO ZENODO
PER: 0.5 — Retained: the operator by name and the observatory's surfaces as cards. Lost: the institution and any identifier.
