On macOS, Claude Code stores credentials in the Keychain under
service "Claude Code-credentials" rather than in a file. When
~/.claude/.credentials.json is absent, shell out to:
security find-generic-password -s "Claude Code-credentials" -w
and parse the result as the same JSON schema.
~/.claude.json holds only profile/UI metadata (oauthAccount has
no token fields). expiresAt in the credentials is milliseconds.

The actual OAuth token is in ~/.claude/.credentials.json under
claudeAiOauth.accessToken, not in ~/.claude.json.
~/.claude.json holds only UI state and profile metadata (oauthAccount
has no token fields). expiresAt in the credentials file is milliseconds,
not seconds.
Discovered after testing against Claude Code 2.1.198.

Reads the host's Claude OAuth session key from ~/.claude.json at launch
and forwards it only to the egress sidecar (never to the agent), placing
a placeholder CLAUDE_CODE_OAUTH_TOKEN in the agent env so Claude Code
starts without seeing the real credential.
Mirrors the existing Codex forward_host_credentials flow (PRD 0029).
Adds claude_auth.py to extract and validate the sessionKey, a
CLAUDE_HOST_CREDENTIAL_TOKEN_REF constant in egress.py, and updates
manifest_agent.py to allow the flag for both 'codex' and 'claude'
templates. Also adds a mutual-exclusion check that rejects setting
both auth_token and forward_host_credentials together.
