The clone-strip and root-write-through in the previous commit stop NEW forks
but leave installs that forked before upgrading in the broken state: each
profile keeps its own copy of the root grant, whichever profile rotated last
holds the only live refresh token, and root plus every sibling still hit
invalid_grant on their next refresh. The PR body asked those users to
re-auth at root and hand-edit profiles/*/auth.json; this makes it automatic.
`heal_forked_single_use_oauth_grants(provider)` (hermes_cli/auth.py) runs at
the top of a profile's `load_pool()` for SINGLE_USE_REFRESH_POOL_PROVIDERS.
Under the profile lock then the root lock it matches each profile OAuth row
to its root counterpart by lineage — same pool id (preserved by both fork
paths), same JWT account identity, same token material, else same provider +
same client (Anthropic pkce grants carry no claims) — keeps the copy with the
freshest rotation (`expires_at_ms` / `last_refresh` / JWT exp), writes it into
ROOT when root's is older, and strips the profile copy (pool rows, the
`providers.<id>` device-code block for Codex/xAI, and a profile-local
`.anthropic_oauth.json`) so the profile borrows root from then on. Root's
singleton and its hermes_pkce row are kept in step so root's own re-seed
cannot resurrect the spent pair.
Guarantees: idempotent (mtime-keyed clean mark skips the locked scan on the
per-call hot path); one INFO line per healed profile; API-key rows untouched;
a row with no root counterpart (root lost its grant, or an independent
account whose claims differ) is never deleted; only the two auth.json files
the root fallback already reads are touched — no environ/secret-scope reads.
`hermes auth list` / `hermes auth status <provider>` print the heal note.
Live repro (real imports, temp root + forge/atlas each holding a pre-fix
verbatim copy, forge already rotated RT0->RT1 into its own file, fake
single-use token endpoint): before — atlas None, forge AT2 (only in forge),
root None; server log 4x REUSE of spent RT0. After — forge's load heals to
root and rotates there, atlas and root select AT2, profiles/*/auth.json hold
no anthropic rows, server log exactly one ROTATE and zero REUSE.
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
