Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-28f0b91e689e5d31 descriptive

Alphabet's Sidewalk Labs planned one of the world's most heavily instrumented neighbourhoods on Toronto's waterfront

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The Guardian and the reference account both describe the Sidewalk Labs proposal for the Quayside site as a sensor-dense district developed by Alphabet's urban innovation subsidiary. No `find` is recorded because no single passage carries the whole description; the density of the proposed instrumentation is spread across each account.
Caveat: The framing is the entry's; the sources describe the density of the proposed instrumentation without ranking it.

Claim 2 clm-0f96e3f62c674d64 quantitative

the project was abandoned in May 2020, officially over pandemic economics

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: CBC, 7 May 2020: 'Sidewalk Labs, a Google-affiliated company, is abandoning its plan to build a high-tech neighbourhood on Toronto's waterfront, citing what it calls unprecedented economic uncertainty.' The Guardian reported the same decision on the same day.
Caveat: No claim-specific caveat recorded

Claim 3 clm-51728fce34d91608 descriptive

The site relaunched as a zero-carbon housing plan with no data layer in it

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Waterfront Toronto describes the replacement as a 'zero-fossil fuel, zero-carbon certified master-planned community' and lists its goals as affordability, design excellence, sustainability and community. Nothing in the agency's account of the scheme describes a sensor or data layer.
Caveat: That the replacement has no data layer is an absence in the agency's own description of it, not something any source states.

Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Verbatim: 'Waterfront Toronto has spent approximately $16.1 million on the project to date. "This cost is the total over the course of nearly three years of work," said Andrew Tumilty, a spokesperson for Waterfront Toronto'.

Published field: impact · verbatim

Claim 6 clm-a8a68c188b395f25 descriptive

a zero-fossil-fuel, zero-carbon community whose stated goals are affordability, design excellence, sustainability and community

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Waterfront Toronto: 'Quayside will be a zero-fossil fuel, zero-carbon certified master-planned community', and 'as with all Waterfront Toronto projects, it has ambitious goals relating to affordability, design excellence, sustainability and community'.
Caveat: No claim-specific caveat recorded

Claim 7 clm-cb63e5c59b14ad56 quantitative

expects construction to start in 2026 and its first residents in 2031, with about 550 affordable and 1,100 market rental homes in the first phase

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Verbatim: 'Construction is expected to get underway in 2026 with the goal of welcoming the first new residents in 2031', and 'The rental homes - about 550 affordable and about 1,100 purpose-built market rental homes - will all be advanced at the same time.'
Caveat: No claim-specific caveat recorded

Claim 8 clm-2898ed628a937363 descriptive

Two years of argument over an 'urban data trust' left the plan without the consent it needed, and the company's own stated reason for walking away was the pandemic economy

Published field: lesson · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The retrospective and the reference account both trace the opposition to the handling of data governance, centred on the proposed urban data trust; the same-day reporting records the company attributing its exit to pandemic economics. No `find` is recorded because the claim summarises three sources rather than quoting one.
Caveat: Which of the two actually ended the project is disputed and no source settles it; this entry deliberately reports both.
