Teknium 3038493ee6 fix(auth): never fork single-use OAuth grants across profiles (#100339)
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

Installation

yarn

Local Development

yarn start

This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.

Build

yarn build

This command generates static content into the build directory and can be served using any static contents hosting service.

Deployment

Using SSH:

USE_SSH=true yarn deploy

Not using SSH:

GIT_USER=<Your GitHub username> yarn deploy

If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the gh-pages branch.

Diagram Linting

CI runs ascii-guard to lint docs for ASCII box diagrams. Use Mermaid (````mermaid`) or plain lists/tables instead of ASCII boxes to avoid CI failures.
