Disability-addition qualification support

21 September 2026. Model-authored source review and bounded implementation; not specialist acceptance, current legal advice or an entitlement decision. This increment changes authored interpretations and evidence requirements. It does not change the captured manuals, legal acquisitions, historical trial packages or public observations.

What changed and why

The previous no-partner definition said that DMG 78055–78057 distinguished actual payment from underlying entitlement. That compressed statement could be read as a cash-payment test for every qualifying disability benefit. The captured guidance is more specific:

• DMG 78057 concerns Carer’s Allowance (CA) or Universal Credit (UC) including the carer element, paid for caring for the claimant or partner. It says this must actually be in payment before it affects the Pension Credit additional amount. The transitional-protection qualification in 78035–78036 remains relevant.
• DMG 78060 treats specified disability benefits as received for particular periods before an award is made but in respect of which it is awarded, or with payment in lieu of an award. It does not say every pending or underlying entitlement qualifies. The captured source specifies that the payment-in-lieu period is not covered by an award.
• DMG 78060’s separate patient provision expressly concerns a claimant who has a partner. Its over-28-days treatment must not become a universal no-partner or temporary-care-home rule. Its final provision treats CA or UC including the carer element as not received before the award is first paid.

The complete 78060 paragraph spans Chapter 78 PDF pages 16 and 17. Both were already captured in the full corpus but absent from the smaller semantic index. They are now selected as whole-page evidence. Page 17 keeps its actual first-payment wording as the acquisition anchor; the producer does not invent a repeated 78060 paragraph number on that page.

DMG means the Department for Work and Pensions’ Decision makers’ guide. An additional amount is a component of Pension Credit, not necessarily the whole award. A dependency here means evidence that must be inspectable with an authored statement; it does not mean a legal rule has been found applicable.

Two existing concepts with different jobs

No new concept or ontology predicate was needed. The existing identifiers, types, aliases and unreviewed authority remain in place.

Small overview

staff-domain/severe-disability-addition is now a navigation and identity overview:

Navigation to the Pension Credit additional amount for people who are severely disabled. The captured guidance identifies separate no-partner and partner branches in DMG 78034 and 78045. The permanent-care-home paragraph 78088 is headed Claimants who have no partner (including self-funders) and requires all its conditions to be satisfied. This additional amount is distinct from the Severe Disablement Allowance benefit described in DMG 57001. This overview does not set out the full qualifying conditions or a consolidated current-law rule.

Its four required pages support only those limited statements. It does not require the detailed no-partner, partner, Scottish-memo or legacy-benefit concept. For example, page 12 establishes the existence of the partner branch; explaining that branch’s conditions would also require its later pages. The overview does not promise that fuller explanation.

SDA remains ambiguous between Severe Disablement Allowance and informal shorthand for the Pension Credit severe-disability additional amount. Both case-sensitive aliases remain. Neither meaning is silently selected.

Bounded no-partner explanation

staff-domain/no-partner-disability-addition now says:

Bounded reading of the captured lower-rate branch for a claimant with no partner. DMG 78034–78036 set receipt, residence and caring conditions and the stated transitional-protection exception. In DMG 78057, Carer’s Allowance or Universal Credit including the carer element, in respect of caring for the claimant or partner, must actually be in payment before it affects entitlement to this additional amount. That is not a universal cash-payment test for disability benefits: DMG 78060 treats specified disability benefits as received for periods before an award is made but in respect of which it is awarded, or periods not covered by an award but with payment in lieu of an award, and treats CA or UC including the carer element as not received before its first payment. Its separate patient provision expressly concerns a claimant who has a partner and must not be transferred to a no-partner care-home case. Under the no-partner heading, DMG 78088 requires all conditions to remain satisfied; funding status alone does not settle them. Read these captured passages with the separate dated changes in memos 02/25, 06/25 and 01/26. This component does not consolidate those changes or determine every residence, ignored-person, funding or hospital rule.

This definition removes the earlier compressed account of ignored-person rules and the first four weeks. Those sources remain available for separate conditional investigation. A shorter definition does not make their detailed rules complete or irrelevant to an eventual answer.

Exact support groups

The concept authoring uses the existing required_source_ids field. The producer verifies that every target belongs to the concept’s captured source selection, then emits the existing Dublin Core dcterms:requires relationship with model-derived, unreviewed status.

Each page identifier has the stable prefix https://chris-page-gov.github.io/okf-dwp/id/. Page numbers are one-based PDF pages, not paragraph numbers. The overview requires four pages, the no-partner component ten, and their union contains eleven distinct pages.

There are 14 new support relationships, giving 29 alongside the existing 15 household, housing-cost and temporary-residence relationships. Each new link goes directly to evidence, so the overview cannot create a dependency cycle or force every detailed branch into its own required context.

Ordinary dcterms:references and skos:related relationships remain navigation unless an explicit dependency is declared. The no-partner record’s existing references to pages 21–23 and the wider Scottish-memo concept remain available; they are not all converted into requirements.

Dated changes and provenance

The four memo pages are required alongside the no-partner receipt explanation because known changes are already available. They are not a silently consolidated rule or a universal list of equivalent benefits:

• Memo 02/25, page 5, paragraphs 13–15: Pension Age Disability Payment (PADP), its role in the meaning of “AA”, qualifying benefits and ignored-person rules; the source states 21 October 2024.
• Memo 06/25, page 3: introduction and source-stated 21 March 2025 date for Scottish Adult Disability Living Allowance (SADLA) changes.
• Memo 06/25, page 9, paragraph 30: the Pension Credit qualifying-benefit change for the claimant or applicable partner. Other housing-cost and polygamous-marriage material on that whole page is not thereby adopted into this definition.
• Memo 01/26, page 3, paragraph 5: the source-stated 15 March 2026 Carer Support terminology change. Paragraphs 5 and 6 use different component wording; the exact text is preserved, not reconciled into a fabricated synonym.

The captured Chapter 78 PDF has SHA-256 d5e17de1d343fc6a6498089897b222a4989914fa53f85af9ddc8c9c05471e2b8. The page extraction has SHA-256 f90fb5e92c5aebf4c07fb3383ca8bc0bb1ded55448949d987ed87e360c6b4894. Acquisition was 2026-09-15T14:21:01Z; the retained HTTP Last-Modified observation was 2026-04-16T15:41:27Z. Neither becomes legal commencement or assurance of current applicability. The earlier component review retains the memo and Chapter 57 PDF/extraction fingerprints and source dates.

These are exact whole-page machine extractions with source locators and hashes. They remain normalised evidence with derived authority, not human-reviewed text.

Staff 012 and 013: inspect a possible branch

The task-profile authoring adds the overview and no-partner component alongside the existing household and housing-cost qualification concepts. Both profiles still start with exactly pension-credit and care-home; no presumed no-partner fact becomes a trigger.

Their existing source-closure obligation labels now explicitly say:

Conditional branch investigation only; inspecting the no-partner branch does not establish that the claimant has no partner.

The existing producer carries that warning into machine-readable requirement limitations. Staff 013’s label also now says qualifying-benefit receipt, with treated-as-receipt qualifications, rather than suggesting actual payment is the only question. These are two intentional label clarifications. Every obligation identifier, category and status remains unchanged; the obligation objects as a whole are not claimed byte-identical.

Every new path begins at the already resolved care-home concept, follows its existing skos:related relationship to the overview or no-partner component, then a direct dcterms:requires relationship to the page. The producer does not seed an intermediate concept merely to retrieve it.

Each profile now has 32 required identifiers and 33 paths, including five still-absent obligation identifiers. Its qualification support covers 22 distinct pages across the four concept groups. Candidate identifiers, question wording, recorded ambiguities and original triggers remain unchanged. All 203 obligations remain open and all 40 profiles remain labelled insufficient.

Verification and measured boundary

The locked environment and existing producer were used; no dependency or producer/schema change was required:

uv sync --locked
uv run --locked python scripts/build_staff_semantic.py
uv run --locked python scripts/build_staff_semantic.py --check
uv run --locked python -m unittest discover -s scripts -p test_staff_semantic.py
uv run --locked python -m unittest discover -s scripts -p test_household_semantic.py

35 staff controls and 11 household controls pass. They check whole-page hashes, an invented page-17 anchor rejection, the exact four/ten-page groups, the 29-edge census, unchanged earlier evidence, receipt and patient qualifiers, memo wording, directed paths from existing triggers, conditional-investigation warnings, open obligations and the preserved SDA alternatives. The existing housing wording test was aligned with the previously corrected “not being let or sublet” wording; its meaning and evidence requirement were not weakened.

A direct probe of the existing Explorer validator accepts the generated index. The resolver returns no resolved concept for SDA and exposes both candidates. This checks identity and ambiguity handling; it is not a package-retention run.

Current semantic source: 903 records, 1,464 assertions, 51 authored concepts, 98 selected source pages, 29 support dependencies and two qualification profiles. The index is 4,683,061 bytes, within the existing 8 MiB bound. Snapshot: dwp-staff-semantics-91e16565bd7c97e72f3b. Index SHA-256: 8aea634f7623a61475156a116fcebf2ae64cbb4b17507a731a7de73edee0ddd7.

An independent read-only review verified the source qualifications, whole-page bindings, acyclic support groups and conditional paths, and repeated all 46 controls successfully. This is agent review, not specialist acceptance.

The combined Reader now carries this increment: 20,044 records and 21,224 relationships, snapshot dwp-combined-872f2476a6e8e5ce6d55. All 4,758 generated files reproduce exactly; 20 Reader controls pass alongside the 46 semantic controls. The 40-case development evaluation and exact replay retain 177 of 177 original candidate occurrences at the default 512 KiB budget.

The separate frozen comparison compares this source at 8ea4465a4cb5a867d82c87e635f2ef1d1df18d8a with the earlier qualification source. All 320 assemblies and exact replay pass. The current allocator retains 497 of 497 declared path occurrences at 512 KiB, but only 407 at 256 KiB. Each care-home package retains all 71 activated paths at 512 KiB; at 256 KiB it retains only 26. Missing qualifications are explicitly reported. The 64 KiB request still refuses with metadata_budget and zero records.

Publication and any model-answer run remain separate work. Earlier observations retain their original source and engine bindings.

Still unresolved

• A detailed ignored-person explanation needs pages 21–24, including the twelve-week limit, close-relative qualifications, shared-lives restriction and complete example. The shorter definition does not provide that full rule.
• Detailed partner lower/higher-rate conditions need pages 12–14 and their receipt/hospital qualifications; the no-partner branch cannot settle them.
• Funding-specific AA/DLA/PIP/Scottish-benefit cessation, normal-residence facts, hospital routes, legal versions, territorial scope and transitions remain to reconcile. Source dates alone do not settle applicability.
• The inspected statutory-body overlay still lacks the complete relevant judgment and provision dependencies, including Schedule I paragraph 3 and R(IS) 11/98 for the detailed ignored-person material.
• A bounded package may still omit support. Any surviving summary must expose its missing dependencies; additional pages or model agreement cannot close the recorded evidence, scope, legal or specialist-review obligations.
