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.
Wire format:
topic_member_key.encrypted_key = base64(
<32-byte sender x25519 pubkey> || crypto_box(topic_key)
)
Embedding sender pubkey inline lets re-sealed copies (carrying a
different sender than the original creator-seal) decode the same
way as creator copies, without an extra schema column or join.
topic.encrypted_key_pubkey stays for backwards-compat metadata
but the wire truth is the inline prefix.
API (phase 3):
GET /v1/topics/:name/pending-seals list members without keys
POST /v1/topics/:name/seal submit a re-sealed copy
POST /v1/messages now accepts bodyVersion (1|2); v2 skips the
regex mention extraction (server can't read v2 ciphertext).
GET /messages + /stream now return bodyVersion per row.
Broker + web mutations updated to use the inline-sender format
when sealing. ensureGeneralTopic (web) also generates topic keys
per the bugfix that landed earlier today; both producers now
share one wire format.
CLI (claudemesh-cli@1.8.0):
+ apps/cli/src/services/crypto/topic-key.ts — fetch/decrypt/encrypt/seal
+ claudemesh topic post <name> <msg> — encrypted REST send (v2)
* claudemesh topic tail <name> — decrypts v2 on render, runs a
30s background re-seal loop for pending joiners
Web client stays on v1 plaintext until phase 3.5 (browser-side
persistent identity in IndexedDB). Mention fan-out from phase 1
already works for both versions, so /v1/notifications keeps
working through the cutover.
Spec at .artifacts/specs/2026-05-02-topic-key-onboarding.md
updated with the implemented inline-sender format and the
phase 3.5 web plan.

Three new verbs that wrap the v1.6.x REST surface:
claudemesh topic tail <name> → live SSE consumer with N-message backfill
claudemesh member list → mesh roster decorated with online state
claudemesh notification list → recent @-mentions of you across topics
Each command auto-mints a 5-minute read-only apikey via the WS
broker and revokes on exit, so users don't manage tokens. SSE
client uses fetch + ReadableStream so the bearer stays in the
Authorization header.
