Anthropic / Codex / xAI OAuth refresh tokens are single-use: a grant copied
into a second auth.json is one credential with two owners, and the first
profile to refresh it revokes the pair for every sibling (invalid_grant /
refresh_token_reused). Two code paths forked grants that way:
1. `hermes profile create --clone-all` and the dashboard/TUI
`mirror_credentials` flow copied auth.json (+ .anthropic_oauth.json)
verbatim. Both now run `strip_cloned_single_use_oauth_grants()`, which
drops OAuth rows for SINGLE_USE_REFRESH_POOL_PROVIDERS, the matching
`providers.<id>` device-code blocks, and the PKCE singleton file; API
keys are still copied. The clone reads the root grant through the
existing credential-pool root fallback.
2. A named profile with no local rows BORROWS the root grant via
`read_credential_pool()`'s fallback, but every persist
(`CredentialPool._persist`, `load_pool` reseed, `remove_index`) wrote the
rows into the profile's own auth.json — materializing a fork on the first
rotation. `persist_pool_entries()` now routes borrowed single-use rows
back to the root store (update-only, under the root lock; never falls
back to a local copy). A borrowed `hermes_pkce` rotation commits its
singleton to the root `.anthropic_oauth.json`, the borrower never prunes
root-seeded rows it cannot see the backing file for, and
`hermes -p <profile> auth add` persists only the profile's own rows.
Live repro (real imports, temp root + profiles, fake single-use token
endpoint): before — first profile rotation RT0->RT1 in profile only; root
and sibling then hit `invalid_grant`, `resolve_anthropic_token()` -> None.
After — rotation lands in root; root and both siblings select AT1, no reuse.
Direction per Teknium: stop cloning OAuth into profiles (ONE grant at root,
children inherit via context) rather than making clones survive. Supersedes
the clone-strip/root-write-through half of #100389 and the init-refresh idea
in #100703 (an expired-but-refreshable row already refreshes on select()).
Closes#100339
