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-c9b3046a482f5c53 quantitative

Launched January 2016, Boston's CityScore compiles daily metrics — 311 response times, fire/EMS response, school attendance — into a single number versus target

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The city's dashboard page sets out the metrics and how they are combined against target; WBUR reported the public launch on 15 January 2016.
Caveat: No claim-specific caveat recorded

Claim 2 clm-b649e8289b9904d9 quantitative

After it flagged strained EMS response times, the mayor's FY17 budget funded 20 new EMTs and 10 replacement ambulances

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The case study on the city's own dashboard page describes the EMS response-time signal and the resulting funding in the FY17 budget.
Caveat: The city's own account of its own dashboard; no independent source traces the budget decision to the score.

Claim 3 clm-5ef49f2bc86a50a8 quantitative

After CityScore flagged strained EMS response times, the mayor's FY17 budget funded 20 new EMTs and 10 replacement ambulances

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The same case study is the only source for the consequence, and it is the city's.
Caveat: A single documented decision, self-reported; ten years on, no independent evaluation of the dashboard is cited.

Claim 4 clm-d5d60c9d2e6c307c descriptive

the inputs are published daily as open data under a public-domain dedication, so anyone who distrusts the number can rebuild it

Published field: lesson · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The CityScore dataset on Analyze Boston confirms the metrics are still published daily as open data under a PDDL public-domain dedication.
Caveat: No claim-specific caveat recorded

Source dossiers and revision state

This layer records what is known about each source, what is still missing, and the exact snapshot this page is rendering. A missing date, archive or hash stays visible as missing.

unreviewed Revision 2026-08-27-claims-and-sources effective 2026-08-27 · created 2026-08-27

Awaiting operator and domain-expert review; publication of this revision implies neither.

Erratum on this revision's envelope. The snapshot, its hash and its permanent link are untouched.

createdAt previously read 2026-09-01T11:00:00Z. The batching script that produced this revision advanced createdAt into the future to satisfy the strictly-increasing order the validator requires per entity. The value never recorded a real event; the corrected value is the moment the revision provably existed in the repository. Corrected to 2026-08-27T03:18:08Z on 2026-08-27; evidence: first appears in commit 52078886be, committed 2026-08-27T03:18:08Z.

Known limits of this passport

Publisher names and source languages have not yet been classified; domains are recorded without guessing.
Existing source notes are descriptive locators, not page- or paragraph-exact citations.
A missing archive, publication date or content hash is shown as null rather than inferred.
The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
