Problem: Built-in preset names and descriptions read like configuration modes
rather than collaborators, and their relationship to Harness prompts was unclear.
Root cause: Technical copy was reused across the catalog, composer and persona
editor without explaining the existing short-identity prompt adaptation.
Fix: Rename the built-ins to Everyday partner and Lightweight partner, update
their bilingual descriptions and guidance, and derive the unbound picker label
from its canonical catalog definition. Keep IDs, persona bytes and selections
unchanged, retain historical translations, refresh revision metadata and document
the pinned official Harness reference and native prompt boundary.
Verification: Frontend 729 files / 5,852 tests and production build/typecheck;
contract, store and HTTP suites; gofmt, vet, lint, changed-file check, builtin and
boot suites. Fix a discovered worktree test race by waiting for the asynchronous
checkout state instead of the creation title shared by initial and checkout
phases. Browser visual acceptance remains unavailable under the URL policy.
