Tracer / Trust
What Tracer's public claims rest on
This is the claim ledger used by the site. Each claim names its evidence status, where it applies, what it does not establish, when it must be reviewed, and the automated gate that checks it.
Measured means shipped code recomputes the claim. Estimated means a model uses assumptions supplied by the reader. Withheld means Tracer deliberately does not publish a conclusion the available evidence cannot support.
Status measured
Metric Credentials or contact details collected before a visitor reaches a result
Denominator Every visitor arriving at the landing page
Baseline A product page that gates the demonstration behind a form
Scope The landing page and the surfaces its calls to action reach
Window Every request
Evidence basis Approved against the positioning gate, which fails on any form or input element
Owner LumiraGroup product owner
Limitations Describes the public surfaces; a paid engagement has its own onboarding
Review by / Expires 2027-08-27
Automated gate test/node/positioning.spec.ts — the landing page collects nothing anywhere on the page
Status measured
Metric Refusal behavior when a status computation lacks a required field
Denominator Every status request over a dataset with a missing required field
Baseline A system that emits a status regardless of missing fields
Scope The status computation and the linter; not the ROI model, which is labeled estimated
Window Every request
Evidence basis Approved against the refusal gate, which fails if a status is computed over missing fields
Owner LumiraGroup product owner
Limitations Bounds confidence in computed status; it is not a claim about the customer's own reporting
Review by / Expires 2027-08-27
Automated gate test/node/refusal.spec.ts — the status refuses rather than computes when a required field is absent
Status measured
Metric Findings the linter returns for the shipped demo export
Denominator All records in the demo export the connector maps
Baseline The finding list the same three gates return at render time
Scope One synthetic export; no customer data
Window Per request
Evidence basis Approved against the recomputed finding count rendered into the same sentence
Owner LumiraGroup product owner
Limitations An auditor's own finding list may differ; this is what Tracer's rules return
Review by / Expires 2027-08-27
Automated gate test/node/demo.spec.ts — the headline gap count equals the recomputed finding count
Status measured
Metric Computability of a status over the demo export
Denominator The fields a status computation requires
Baseline A status figure produced despite absent fields
Scope The shipped demo export only
Window Per request
Evidence basis Approved against the status result rendered on the page, not against fixed copy
Owner LumiraGroup product owner
Limitations Names which fields blocked this computation, not the quality of the underlying delivery
Review by / Expires 2027-08-27
Automated gate test/node/demo.spec.ts — the status-refusal claim is true, the export really is not computable
Status measured
Metric Persistence of pasted export content after a scan
Denominator Every scan request the public endpoint accepts
Baseline A scanner that retains uploads for later analysis
Scope Export content only; the route, response code, and duration are recorded as analytics
Window Every request
Evidence basis Approved against the deployed Worker's bindings — no database, file store, or cache
Owner LumiraGroup product owner
Limitations Not a claim about the visitor's own network or browser history
Review by / Expires 2027-08-27
Automated gate test/node/data-boundary.spec.ts — the Worker keeps record content out of logs and analytics
Status measured
Metric Model invocations on pasted export content
Denominator Every scan request
Baseline A scanner that routes content to a language model
Scope The scan path; the checks are deterministic heuristics over the text
Window Every request
Evidence basis Approved against the shipped gates, which call no model
Owner LumiraGroup product owner
Limitations Applies to Tracer's processing, not to anything the visitor does with the output
Review by / Expires 2027-08-27
Automated gate test/node/data-boundary.spec.ts — the disclosure names model use before the visitor can paste
Status estimated
Metric Evidence-preparation hours and currency avoided in a year
Denominator Hours the reader states their team spends assembling review evidence
Baseline The reader's current assembly effort, as the reader states it
Scope Evidence preparation only; no other work is modeled
Window One year, at the review cadence the reader supplies
Evidence basis Approved as a modeled scenario over reader-supplied inputs; Tracer supplies no input value
Owner LumiraGroup product owner
Limitations Modeled forward from assumptions Tracer has not measured; not a measurement and not a guarantee
Review by / Expires 2027-08-27
Automated gate test/node/roi.spec.ts — every input renders blank and the output is labeled a modeled scenario
Status withheld
Metric Confidence attached to the modeled result
Denominator Outcome observations that would support a confidence band — currently none
Baseline A model that publishes a confidence percentage without outcome data behind it
Scope The ROI model only; computed metrics state their own status
Window Until outcome data exists to derive a band from
Evidence basis Approved as an explicit absence, matching how an unsourced metric is reported
Owner LumiraGroup product owner
Limitations The spread between the reader's three scenarios is the only uncertainty shown
Review by / Expires 2027-08-27
Automated gate test/node/roi.spec.ts — confidence is reported not_connected rather than invented
Status withheld
Metric Currency value attributed to defects not found
Denominator Not applicable — the arithmetic is absent from the page
Baseline A business case that prices defects the customer never experienced
Scope The whole ROI page; there is no toggle that enables it
Window Permanent, until direct evidence of a customer defect outcome exists
Evidence basis Approved as a deliberate omission under the outcome-claim policy
Owner LumiraGroup product owner
Limitations Tracer names traceability gaps; it does not claim what closing them causes downstream
Review by / Expires 2027-08-27
Automated gate test/node/roi.spec.ts — no monetized-defect arithmetic appears on the page
