Arrows describe the origin of a **specific statistic**, not a claim that whole publications are dependent in every respect.

| Downstream item | Underlying origin | Evidence for relationship | Status / limitation |
|---|---|---|---|
| S10 TechInsights | S1 Synergy | Explicit Synergy authorship and matching release text/date | Same-origin republication; not another market estimate |
| S11 TechTarget | S1 Synergy | Explicit link and attribution for $119.1bn | Secondary reporting, not independent market measurement |
| S17 Omdia chart | S2 Omdia | Embedded chart, label and Cloud Channels Analysis credit | Same dataset family |
| S12 Yahoo | Omdia via Business Wire | Visible wire credit and matching release text | Syndication; original wire landing page not fully inspected |
| S13 Intelligent CIO | S2 Omdia | Omdia attribution, matching quarter/value/growth | Downstream source family; exact path via wire vs direct not established |
| S6 Omdia catalog | Related Q4 data product | Public quarter/title/abstract | Do not assert identical revision vintage to S2 |
| S7 Canalys PDF | Historical Canalys analysis | Original surviving analyst PDF | History, not automatic proof of 2025 continuity |
| S9 Amazon | Company financial disclosure | Quarter ended December 2025, AWS sales table | Separate primary evidence for a different metric; not a third market-size estimate |

The headline comparison has **two statistic origins**. Extra pages repeating either release do not add independent empirical confirmation.

## A concrete transmission discrepancy
S11's live prose assigns Google 15%; its chart gives 14%, and S1 gives 14%. The dossier retains the discrepancy and uses the original's 14%. This is an observed inconsistency, not a claim about how or why it arose. Extractor metadata also differed from the visible date/byline; the visible source was used.

## What the map does not establish
Shared source lineage does not establish coordinated bias, commercial influence, ownership causality, quality of modeling or accuracy. Synergy and Omdia publish separate estimates; their underlying raw-data independence cannot be audited from public releases.
