Adds a reply_to_id column (self-FK on topic_message) plus end-to-end
plumbing so a message can mark itself as a reply to a previous one in
the same topic.
- Schema: 0027_topic_message_reply_to.sql adds reply_to_id with
ON DELETE SET NULL + index for backlink lookup.
- Broker: appendTopicMessage validates parent shares the topic, writes
reply_to_id; topicHistory + topic_history_response surface it; WS
push envelope now carries senderMemberId, senderName, topic name,
reply_to_id, and message_id so recipients have everything they need
to reply without a follow-up query.
- REST: POST /v1/messages accepts replyToId (validated server-side);
GET /messages and SSE /stream emit it per row.
- CLI: \`topic post --reply-to <id|prefix>\` resolves prefixes against
recent history; \`topic tail\` renders an "↳ in reply to <name>:
<snippet>" line above replies and shows a copyable #shortid tag on
every row.
- MCP push pipe: channel attributes now include from_pubkey,
from_member_id, message_id, topic, reply_to_id — the recipient can
thread a reply directly from the inbound notification.
- Skill + identity prompt updated to teach Claude how to use the new
attributes for replies.
Bumped CLI to 1.9.0.
Adds v1.7.0 (terminal parity) and v1.8.0 (per-topic encryption)
verbs to the bundled claudemesh skill so Claude Code sessions
discover them via the auto-installed SKILL.md instead of the
README-only path.
Sections added:
- topic tail / topic post under the topic block
- member resource (distinct from peer)
- notification resource
- per-topic encryption block — explains v2 ciphertext marker,
re-seal flow, and 404 behaviour
