# Pack 2 learning-and-transition population review

Review date: 2026-08-08

Delivery item: `PACK-002`

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

GitHub Pages was not updated; publication remains unchanged until explicitly requested.

## Completed denominator

The pack accounts for exactly 36 approved families:

- 12 in School years;
- 12 in Transition to adulthood; and
- 12 in Further education, university and research.

Thirty-five new dossiers and service narratives were rendered. The existing
`learn-to-drive-car` vertical-slice dossier and narrative were preserved rather
than overwritten, so the cumulative corpus contains 77 distinct
population-complete family dossiers. The three new domain narratives describe
six approved enclosing processes.

Every newly rendered dossier declares separate England, Scotland, Wales and
Northern Ireland route variants, a two-step ordinary journey and an exception
or route-failure journey. Devolved topic pages are discovery handoffs only and
do not establish shared eligibility, evidence, costs, deadlines or outcomes.

## Sources, rights and review boundary

The three domain registers contain 44 current official links: 35
topic-specific primary pages and nine shared devolved handoffs. All 44 passed
the metadata-only audit recorded under
[`evaluation/link-receipts/pack-2-learning-transition-2026-08-08`](../link-receipts/pack-2-learning-transition-2026-08-08/).
Every receipt records `response_body_retained: false`.

The sources use 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 response body or snapshot was retained or
redistributed.

All newly rendered families require specialist review before legal, clinical,
safeguarding, educational-entitlement or other high-impact operational claims
are release-grade. Population completion does not imply specialist acceptance.

## Search acceptance

Static search passed for all 72 staged canonical titles and registered aliases,
with the intended family in the first five. All twelve enclosing-process titles
for the six staged domains are searchable. The cumulative 26 natural-language
competency questions return their expected family in the first ten and cover
all six staged domains and all four nations. An unmatched query returns no
invented result.

## Generated projection

The locally generated data plane reconciles:

- 293 service families;
- 77 population-complete dossier-backed families;
- 3,496 total typed concepts;
- 300 typed link-only source assertions;
- 4,850 provenance-bearing governed relationships;
- 397 dated GSS geographies and 438 shared organizations; and
- four 1,000-record chunks for record hydration.

Representative deterministic artifact hashes were:

| Artifact | SHA-256 |
|---|---|
| `okf-explorer.json` | `0f5412e3f41ee300b11a592ec5e4b6fe6cd6d73b78929d5b09e6349b3f515f36` |

## Local checks

`make validate` passed through the locked `uv` environment: 148 rendered pack
files, 274 browser handoffs, six domain registers, 77 dossiers, 300 resolved
source assertions, deterministic semantic projections, canonical and natural
language search acceptance, rights checks and 96 unit tests were green.

## Visible Explorer journeys

The no-cache local Explorer overlay at `127.0.0.1:8011` passed these journeys
against the exact regenerated projection:

1. overview showed 3,496 concepts, 300 resources, 4,850 relationships and 77
   population-complete families;
2. alias search `DSA application` returned only `Get Disabled Students'
   Allowance` and reported an alias match;
3. Narrative displayed `Enter and fund post-school study`, ordinary and
   exception handoffs, what may follow and four nation-specific official routes;
4. Graph centred the family and exposed 28 relationships including the
   enclosing process, life-course domain, ordinary and exception episodes,
   four jurisdictions, actors, user needs and source assertions; and
5. Resources exposed four typed official links. Selecting the England source
   displayed its original summary, host, linked-reference format and official
   URL without offering or retaining an inline source response.

## Remaining boundary

This pack completes discovery coverage for its 36 accounted families. It does
not claim bounded typo tolerance in Explorer, release grade, named specialist
acceptance, personalized decisions, source-content redistribution, a frozen
candidate or publication. `PACK-003` is the next bounded implementation unit.
