# Research method and limits

<blockquote class="governing-question">
<p>What do the Thirlwall Inquiry’s recommendations mean for Defence healthcare, and what must be checked against internal policy?</p>
</blockquote>

## Purpose and audience

This wiki supports Defence healthcare leaders, clinical governance teams, legal advisers, safeguarding leads and assurance staff. It explains the legal and regulatory implications of the Thirlwall Inquiry, tracks public responses and identifies matters requiring internal policy confirmation. It is a reference wiki, with no pilot exercises, invented scenarios or worked examples.

Defence healthcare is the main focus. Wider Defence lessons are included where the relationship is clear. Specialist neonatal recommendations remain visible so that relevance is assessed, rather than assumed or silently excluded.

## Evidence boundary

The source collection contains public Inquiry material, legislation, professional standards and official public Defence sources. It excludes non-public Defence policy, internal operational detail and internally validated gap findings. The user confirmed this boundary and asked for specific internal checks.

The initial public-source review was completed on **7 October 2026**. Later additions retain their own check dates. An older document may remain relevant when it is the authority's current publication. Conversely, a recent upload is not proof of an operative policy change. The [source register](https://thirlwall-wiki.pages.dev/sources/index.md) distinguishes document issue dates, landing-page updates and research checks.

## Comparison method

1. Identify the recommendation, its recipient and any stated deadline.
2. Read the supporting report chapter and retain relevant qualifications.
3. Identify the legal or regulatory mechanism and its scope.
4. Find a current official public source for comparison and record its version and limits.
5. Explain the provisional implication for Defence healthcare.
6. Identify which matters depend on internal policy or service-specific applicability.
7. Distinguish an official response, a published document and evidence of delivery in the [public tracker](https://thirlwall-wiki.pages.dev/implementation/index.md).

The [recommendation review](https://thirlwall-wiki.pages.dev/recommendations/index.md) covers all 17 recommendations. The [internal checks](https://thirlwall-wiki.pages.dev/internal-policy-checks/index.md) add a preliminary scope check without presenting it as an additional Inquiry recommendation.

## Meaning of the labels

| Label | What it establishes | What it does not establish |
|---|---|---|
| Inquiry recommendation | What the report recommends to its named recipients | A new legal duty by itself |
| Public requirement | What an identified current source says within its scope | Automatic application to every Defence setting |
| Official response | A stated position or commitment by the responsible body | Delivery of the commitment |
| Published direction or instrument | A specific instruction, guidance or legal text that can be inspected | Compliance, commencement or effectiveness unless separately evidenced |
| Public implementation evidence | An observed finding within the source's sample and period | Performance across the whole organisation |
| Provisional implication | A reasoned question or possible action derived from public evidence | A validated policy or operational gap |
| Internal check required | Evidence is needed from an authorised separate review | Absence of a rule or control |

## Applicability comes before gap assessment

Before comparing wording, identify the provider, workforce status, location and activity. Distinguish Defence-provided care from care delivered by NHS or other providers. Statutory regulation, professional obligations, Defence regulations and contractual requirements may have different routes of application. See the [rules and responsibilities](https://thirlwall-wiki.pages.dev/defence-comparison/index.md) and [scope check](https://thirlwall-wiki.pages.dev/internal-policy-checks/index.md#check-00).

This wiki does not offer a legal determination for a particular service. Its applicability questions remain unresolved where service-specific evidence is unavailable.

## Currentness and uncertainty

A document is described as currently published when the responsible authority links it and no withdrawal notice was observed. This is bounded public evidence. It does not certify alignment with internal versions. Government acceptance, legislative enactment and practical implementation of a recommendation are separate states.

The [validation queue](https://thirlwall-wiki.pages.dev/validation-queue/index.md) records unresolved matters, including any source disagreement. A lack of public evidence remains an evidence limitation. It is not converted into a finding of non-compliance.

## Maintaining the separation

Keep the specific questions in this wiki. Store internal answers, policy extracts and evidence in an approved internal system. If an approved public response later becomes available, register it as a new source and review the affected assessment. Do not copy material back merely because it informed the separate review.
