# Examples from reviewed curriculum work

These historical reports explain decisions, not the current deployed state or
a fresh certification of their coverage. Read current topic data before applying
an example. Shared rules live in [principles](principles.md) and
[alignment guidelines](alignment-guidelines.md).

## Repetition across grades is often reuse

The [Australian cleanup](../../reports/acara-v9-cleanup-2026-10-23.md) reviewed
314 additions and later edited topics. It retired 106 original additions after
redistributing requirements, retained other claims with varied edits, and added
seven focused claims separately. Its initial review categories were not deletion
counts. Use the linked ledgers to trace individual dispositions rather than
inferring that every merge candidate was a redundant whole topic.

The deciding question was what evidence established mastery. Grade, context or
medium alone did not justify new topics; distinct practical operations such as
sawing, drilling, adhesive joining and sewing retained separate destinations.
Do not generalize this into a rule that all tool use is either identical or distinct.

## Many expectations can map without new claims

The [Ontario Grade 3 Maths pass](../../reports/ontario-grade3-mathematics-2026-10-23.md)
reused 114 existing topics and added none, with a congruence extension and
prerequisite repairs recorded separately. Reuse can still involve a semantic
change; inspect its evidence rather than describing every association pass as
claim-preserving.

## Links can leave performance conditions unresolved

The [Ontario Grade 5 Language pass](../../reports/ontario-grade5-language-2026-11-02.md)
added 306 links across 161 existing topics with no new topics, while retaining
four resource/performance conditions. The associated mapping explains the
conditions. Counted links did not make every expectation Full or establish a
learner's ability to perform the complete task.

Likewise, the Australian cleanup preserved links to all 593 selected codes but
did not independently recertify 572 historical Full judgments. Report that limit
instead of treating retained links as new coverage evidence.

## Ingestion is a separate achievement

The [NCERT provenance entry](../../PROVENANCE.md#ncert-foundational-learning-outcomes--identifiers-and-source-links-only)
records 67 selected Grades 1–2 Maths outcome bullets, official parent competency
codes and generated outcome-position identifiers. It explicitly separates that
partial catalogue from topic alignment and wider Indian curriculum coverage.
Its source verification does not certify that any existing topic meets an outcome.
