# Pack 1 family-beginnings population review

Review date: 2026-08-08

Delivery item: `PACK-001`

Result: **passed for local population-complete discovery**

Publication status: local validation only. GitHub Pages was not updated.
Publication requires an explicit owner request.

## Completed denominator

The pack accounts for exactly 36 approved families:

- 12 in Before birth and starting a family;
- 12 in Birth and the newborn period; and
- 12 in Early years.

Each family has a compact domain-register entry, a rendered
`life-course-family.v1` dossier and an authored service narrative. The three
domains also have domain narratives. Every dossier is mapped to its approved
enclosing process, declares England, Scotland, Wales and Northern Ireland
route variants, and contains a two-step ordinary journey plus an exception or
route-failure journey.

National topic pages used outside their topic-specific primary coverage are
labelled `authoritative-national-discovery-handoff`. They locate the current
service and do not support a leaf eligibility rule, cost, deadline or outcome.
Similar labels do not establish national equivalence.

## Sources, rights and review boundary

The three domain registers contain 45 current official links: 36
topic-specific primary pages and nine shared devolved handoffs. All 45 returned
HTTP 200 during the metadata-only audit recorded under
[`evaluation/link-receipts/pack-1-family-beginnings-2026-08-08`](../link-receipts/pack-1-family-beginnings-2026-08-08/).
Every receipt records `response_body_retained: false`.

The sources use previously approved host-level rights decisions for GOV.UK,
NHS England, mygov.scot, GOV.WALES and nidirect. Project use remains links and
original summaries only. No source content, response body or snapshot was
retained or redistributed.

Thirty-five families visibly require specialist legal, clinical,
safeguarding or high-impact operational review before release grade. Public
library child services is marked `not_required` at this discovery level.
Population completion does not imply specialist acceptance.

## Search acceptance

Static search passed for all 36 canonical titles and 72 registered aliases,
with the intended family in the first five. The six Pack 1 enclosing-process
titles are searchable. All 13 natural-language competency questions return the
expected family in the first ten and collectively cover the three domains and
all four nations. An unmatched query returns no invented result.

## Generated projection

The locally generated data plane reconciles:

- 293 service families;
- 42 population-complete dossier-backed families;
- 2,485 total typed concepts;
- 160 typed link-only source assertions;
- 2,894 provenance-bearing governed relationships;
- 397 dated GSS geographies and 438 shared organizations; and
- three 1,000-record chunks for both record and search-result hydration.

Representative deterministic artifact hashes were:

## Local checks

`make validate` passed through the locked `uv` environment: renderer drift,
browser handoffs, OKF bundle, all profile/source/inventory/rights contracts,
domain registers, dossiers, authority infrastructure, large projection, search
acceptance and 94 unit tests were green before the search-acceptance regression
test was added. The final rerun includes that test.

## Visible Explorer journeys

The local no-cache Explorer overlay at `127.0.0.1:8011` passed these journeys:

1. overview showed 2,485 concepts, 160 resources and 2,894 relationships;
2. alias search `book a midwife` returned only `Start antenatal care` and stated
   that its aliases and search text matched;
3. Narrative displayed the enclosing pregnancy/maternity process, the
   ordinary and exception handoffs, four explicit national routes and what may
   follow;
4. Graph centred the family and exposed ordinary and exception episodes,
   process, domain, four jurisdictions, actors, user needs and all four source
   relationships; and
5. Resources displayed the four typed links, and selecting the NHS England
   page exposed its original summary, host and active official URL without an
   inline source-body view.

## Remaining boundary

This pack completes discovery coverage for its 36 families. It does not claim
release grade, named specialist acceptance, exhaustive duplicate council
pages, personalized decisions, source-content redistribution, a frozen
candidate or publication. `PACK-002` is the next bounded implementation unit.
