(1) Voice: _voice_examples now picks the sender's prior sent emails OF THE SAME PURPOSE (PURPOSE_PATTERNS keyword cues per outreach type), larger sample (8) weighted by purpose then recency — not just recent. meta carries on_topic for transparency. (2) Tier-B sending (gmail.compose now authorized in Workspace DWD). New email_integration/compose.py create_outreach_draft: mints a compose-scoped DWD token for the sender (credentials._mint/access_token_for parameterized by scope; GMAIL_COMPOSE_SCOPE), builds an RFC822 message, and POSTs gmail.drafts.create into the SENDER's mailbox — as an in-thread reply (threadId + In-Reply-To/References, recipient = matched LP address) when there's an active thread, else a fresh email. NEVER sends — the human sends from Gmail (guardrails #4, #6). Route POST /api/outreach/gmail-draft; UI "Create Gmail draft" button + "Open Gmail Drafts" link. Tests: test_compose.py (parse/reply-target/RFC822+threading). Message construction unit-verified; the live drafts.create runs on the box. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
