Evidence base

This section makes the current focused corpus browsable without weakening its evidence boundaries. The canonical analytical source remains the included-case dataset; every catalogue, profile, map and report page is a deterministic view of controlled records.

Choose an evidence route

• Corpus profile — temporal, workflow, care-pathway and evidence-status distributions.
• All included reports — the complete 112-report catalogue and individual source-linked records.
• Case–mechanism/evidence map — workflow × mechanism coverage, report matrix and complete per-code membership lists.
• Official response evidence — all registered recipient letters and explicit follow-up gaps.
• Counter-positions and anomalies — bounded disagreements, compatible clarifications, remedy counter-risks and documentary anomalies.
• Evidence assurance and uncertainty — qualified rows, response gaps, selective claim coverage and open validation gates.
• Selection and coverage flow — retained candidate decisions and the distinct 2018 archive-disposition gap.
• Data, citation and reuse — canonical downloads, checksums, citation guidance and rights boundary.

What inclusion means

An included row records a PFD report containing a relevant electronic-record, digital-workflow, interoperability, information-flow or health-IT concern under the focused protocol. Inclusion does not mean that:

• the digital issue caused or contributed to the death;
• a named product has a general defect;
• the concern is prevalent across the NHS or Defence;
• a response was received, complete or independently verified;
• a proposed action was implemented or effective; or
• an empty map cell is an evidence gap.

Each generated report page links to its registered primary Judiciary source and preserves extraction confidence, qualification, response status and any registered counter-position. Downstream Defence links are read from the canonical REQ- register and remain analytical translations rather than coronial recommendations.

Status fields that matter

• High-confidence extraction means the full primary report was checked and the digital mechanism is explicit in the report-specific concern or circumstances. It is not a causal-certainty score.
• Qualified extraction means the digital mechanism, remedy or causal relevance is indirect, contested or dependent on respondent context; the limitation is shown on the report page.
• Response evidence noted means one or more official response attachments are registered for that report. It does not mean every recipient responded or that action was implemented.
• Not assessed makes no claim about whether a response exists. No official response located records only the result of the existing search.
• Care-pathway and primary browsing facets are conservative single-reviewer navigation coding pending independent recheck.

The full field dictionary and controlled values are in the sociotechnical coding framework. Source roles are in source types and authority. Open exclusions, rechecks and release gates remain in the validation queue.
