Closes the gap where parents sending a new email (instead of replying)
would lose their registration progress. All changes follow the
email-based-conversation-matching OpenSpec change.
Key changes
-----------
storage/json_store.py
- normalize_email() helper (lowercase + trim)
- Conversations now keyed by sender email address, not thread ID
- Versioned registration storage: data/registrations/<email>/v<N>_<ts>.json
- current.json always reflects the latest version
- save_registration() returns (email_key, version) tuple
- save_registration_version() for updates with change_summary
- get_registration_history() returns all versions in order
models/conversation.py
- Added last_inbound_message_id field for reply threading (not matching)
channels/email_channel.py
- fetch_unread_messages() no longer exposes thread_id
- Conversation matching removed from channel layer (now in agent)
- Removed _resolve_thread_id() — threading headers kept for SMTP only
agent/core.py
- process_message() takes parent_email + inbound_message_id (no thread ID)
- Looks up conversation by normalized email address
- Post-completion handler: detects intent (question / update / new_child)
- Registration updates: diffs old vs new, versions storage, notifies admin
agent/prompts.py
- build_system_prompt() dispatches to registration or post-completion prompt
- Post-completion prompt guides LLM to return intent field
- Reminder language updated: no expiration threats
notifications/notifier.py
- notify_admin() accepts version parameter
- notify_registration_update() sends "Registration Updated" emails with diff
- _build_update_body() includes field-level old→new change summary
main.py
- Poll loop passes parent_email + inbound_message_id to agent (no thread_id)
