Summary

The design record for itd-2609211913453478: the record-families page, the three retirements and the lint, from the vocabulary rulings of 2026-09-21 (adr-2609212115255771).

Scope

1. The page glossary/core/record-families.md, a table with the seven families and a prose paragraph per axis (lifecycle; position); glossary/core/README.md indexes it first (criterion 1).
2. Superseded entries: phase.md, roadmap.md set status: superseded, superseded_by naming the page and the successor; a milestone.md entry is added in the superseded state, since the word had only lived as a forbidden synonym; roadmap/README.md and roadmap/phases/README.md open with the retirement line (criterion 2).
3. New entries bundle.md, step.md from the template, status: stable; the page's batch row (criterion 3).
4. The lint: glossary_terms gains the two checks beside the existing entry-shape check (criterion 4).
5. The brief: 01-product/03-mental-model.md rewritten to the three layers plus steps, bundle and release; the surface chapters that say "phase" repointed (criterion 5).

Out of scope

• Renames; itd-78; the release press release.

Approach

Prose and one lint rule; the lint reads the page's table as the closed set of families. The retirement lines are one sentence each pointing at the decision record.

Footprint

• packages: internal/core/lint (glossary_terms), .abcd/development/brief/glossary, .abcd/development/brief/01-product
• tests: the two lint checks over fixtures; the page's table parsed; the superseded entries' status

How the criteria are satisfied
