T25 — Types only narrow, end to end #2427
Description
Task
| slice | size | difficulty | model | who | estimated lines |
|---|---|---|---|---|---|
| Types only narrow | S | routine | light | an agent | 160 (40 code, 120 tests) |
declare a Box Type that extends task, and see an entry that breaks its constraints refused at expansion and again at the daemon.
Covers:
- none
Layers:
- slice:
- crates/minimald/src/box_manager/tests.rs: tests
cargo nextest run -p minimald derived_task_type_refused_at_expansion_and_admission
Waits on:
- T22 — Resolve Box Types to a built-in root #2420
- T23 — Check type constraints last, and let a derived type only narrow #2424
- T24 — Re-check the built-in root's constraints at admission #2425
