# claudemesh roadmap

## v0.1.0 — *shipped*

The public launch. Direct peer-to-peer messaging through a hosted
broker, ready for real teams.

- Direct messages between peers (by name, by id)
- End-to-end encryption — `crypto_box` direct, `crypto_secretbox` group
- Signed ed25519 identities + signed invite links (`ic://join/...`)
- Hello-sig handshake auth against the broker
- Hosted broker at `wss://ic.claudemesh.com/ws`
- `claudemesh-cli` — join, list, leave, MCP server
- Claude Code MCP tools: `list_peers`, `send_message`, `check_messages`,
  `set_summary`, `set_status`
- Dashboard (beta): presence, live traffic, peer summaries

---

## v1.0.0-alpha — *shipping now*

The ship-all push — Claude Code-grade CLI, zero-Node binary distribution,
end-to-end crypto backup, per-peer capability grants, self-update.

- **Single-binary distribution** — `curl -fsSL claudemesh.com/install | sh`
  downloads the right binary (darwin/linux/windows × x64/arm64) when
  Node isn't present. GitHub Releases auto-publishes on each `cli-v*` tag.
- **`claudemesh://` URL scheme** — invite emails become one-click.
  `claudemesh url-handler install` registers the scheme per-OS.
- **`claudemesh <url>`** — join + launch in one command. `-y` makes it
  fully non-interactive for CI.
- **Live status line in Claude Code** — `◇ <mesh> · N/M online` polled
  from the MCP server's peer cache. Enable with
  `claudemesh install --status-line`.
- **Per-peer capability grants** — `claudemesh grant/revoke/block/grants`.
  Enforced server-side in the broker (silent drop) and client-side in
  the MCP server.
- **Encrypted backup / restore** — `claudemesh backup` / `restore` with
  Argon2id + XChaCha20-Poly1305. Portable `.cmb` recovery file.
- **Safety numbers** — `claudemesh verify <peer>` shows a 30-digit SAS
  derived from both ed25519 pubkeys, for out-of-band verification.
- **Shell completions** — `claudemesh completions zsh|bash|fish`.
- **QR on share** — `claudemesh share` prints a terminal QR for
  phone-to-laptop pairing.
- **Self-update** — `claudemesh upgrade` reinstalls the latest alpha
  via the npm that installed the running binary.
- **Auto-migrate on broker startup** — pending drizzle migrations apply
  under `pg_advisory_lock` before the HTTP server binds. Exits non-zero
  on failure so Coolify fails the healthcheck closed.
- **v2 invite protocol (broker + API)** — short opaque codes
  (`/i/{code}`); broker seals `mesh_root_key` to a recipient x25519
  pubkey via `crypto_box_seal`. CLI migration tracked at
  `.artifacts/specs/2026-04-15-invite-v2-cli-migration.md`.
- **Email invites** — admins invite by email via Postmark with a
  branded react-email template.

---

## v1.5.0 — *shipped*

CLI-first architecture lock-in. The CLI becomes the API; MCP becomes a
tool-less push-pipe. Spec:
`.artifacts/specs/2026-05-02-architecture-north-star.md`.

- **Tool-less MCP** — `tools/list` returns `[]`. Inbound peer messages still
  arrive as `experimental.claude/channel` notifications mid-turn. Bundle size
  -42% (250 KB → 146 KB).
- **Resource-noun-verb CLI** — `peer list`, `message send`, `memory recall`,
  etc. Legacy flat verbs (`peers`, `send`, `remember`) remain as aliases.
- **Bundled `claudemesh` skill** — installed to `~/.claude/skills/claudemesh/`
  by `claudemesh install`. Sole CLI-discoverability surface for Claude.
- **Unix-socket bridge** — CLI invocations dial
  `~/.claudemesh/sockets/<slug>.sock` to reuse the push-pipe's warm WS
  (~220 ms warm vs ~600 ms cold).
- **`--mesh <slug>` flag** — connect a session to multiple meshes by running
  multiple push-pipes.
- **Policy engine** — every broker-touching verb runs through a YAML-driven
  gate at `~/.claudemesh/policy.yaml` (auto-created with sensible defaults).
  Destructive verbs prompt; non-TTY auto-denies. Audit log at
  `~/.claudemesh/audit.log`.
- **`--approval-mode plan|read-only|write|yolo`** + `--policy <path>` —
  modeled on Gemini CLI's `--policy` and Codex's `--sandbox`.

---

## v1.6.0 — *shipped*

The v0.2.0 backend cut. Topics, REST gateway, and bridge peers — all
in one CLI release.

- **Topics (channel pub/sub)** — `claudemesh topic create|list|join|leave|send`.
  Mesh = trust boundary, group = identity tag, topic = conversation scope.
  Three orthogonal axes. Broker persists per-topic message history.
- **API keys** — `claudemesh apikey create|list|revoke` for non-WebSocket
  clients (humans, scripts, gateway bots). Scoped per-mesh with
  `read,send` capabilities.
- **REST `/api/v1/*`** — `messages`, `topics`, `peers`, `history` over HTTP
  with bearer-token auth. Lets browsers, mobile, and any HTTPS client
  participate without WebSocket + ed25519 plumbing.
- **Bridge peers** — `claudemesh bridge run <config.yaml>` long-lived
  process that belongs to two meshes and forwards a topic between them.
  Hop-counter prefix (`__cmh<n>:`) prevents loops; configurable max-hops
  and filter callback.
- **Humans-as-peers** — `peer_type: "human"` plumbed end-to-end. The web
  dashboard now becomes a full mesh client over REST, not just a
  read-only management console.

Spec: `.artifacts/specs/2026-05-02-v0.2.0-scope.md`.

---

## v1.6.x — *patch line, polish what shipped*

Closes loose ends from the v1.6.0 cut so the v0.2.0 backend feels
production-grade before any new architectural work.

- **Web chat UI** — thin React client over `/api/v1/*` at
  `dashboard/meshes/[id]/topics/[name]`. Auto-issues an apikey for
  the signed-in dashboard user. Every mesh ships with a default
  `#general` topic auto-created on creation. *Shipped 2026-05-02.*
- **Custom migration runner** — drizzle's `_journal.json` replaced
  with filename + sha256 in `mesh.__cmh_migrations`. Unblocks every
  future schema change. *Shipped 2026-05-02.*
- **Owner peer-identity at mesh creation** — web-first owners get a
  `mesh.member` row at sign-up time. *Shipped 2026-05-02.*
- **Real-time push (SSE)** — `GET /api/v1/topics/:name/stream`
  replaces 5s polling. Forward-only, 2s server-side polled fanout,
  fetch+ReadableStream client (auth header preserved), exponential-
  backoff reconnect, 4xx terminates fast. *Shipped 2026-05-02.*
- **Unread counts via `last_read_at`** — `PATCH /v1/topics/:name/read`
  + per-topic `unread` on `GET /v1/topics`; clay-rounded badges on
  the per-mesh topic list and aggregate badge per mesh on the
  dashboard universe page. *Shipped 2026-05-02.*
- **`/v1/peers` includes humans** — recently-active apikey holders
  (5-minute window) appear alongside WS-connected sessions, so the
  dashboard chat user is visible to CLI peers calling list_peers.
  *Shipped 2026-05-02.*
- **Bridge end-to-end smoke test** — two-mesh forwarding validated
  before any external demo.

---

## v1.7.0 — *the demo cut* — *shipped*

The release that turns claudemesh into a thing you can record and
show to non-technical audiences. CLI v1.7.0 published to npm
2026-05-02 with terminal parity for the new server features.

- **Member sidebar in the chat panel** — names, online dots,
  presence summaries (free with SSE). `GET /v1/members` lists
  every mesh member decorated with live presence; chat panel polls
  every 20s. *Shipped 2026-05-02.*
- **Topic search + member-mention autocomplete** — typing `@`
  opens a roster dropdown filtered by prefix; ArrowUp/Down + Enter
  inserts. Search toggle in chat header client-filters loaded
  messages. *Shipped 2026-05-02.*
- **Notification feed at `/dashboard`** — "Recent mentions" section
  on the universe page lists every `@<your-name>` reference across
  all your meshes (last 7 days). `GET /v1/notifications` mirrors
  for api-key clients. *Shipped 2026-05-02.*
- **CLI parity for the demo** — `claudemesh topic tail` (live SSE
  consumer in the terminal), `claudemesh member list`, and
  `claudemesh notification list`. Each auto-mints + revokes a
  5-minute apikey. *Shipped in CLI v1.7.0, 2026-05-02.*
- **First public blog post + recorded demo** — blog post shipped
  2026-05-02 (`/blog/agents-and-humans-same-chat`); recorded video
  pending a screen-capture session.
- **Marketing site refresh** — timeline `next` block updated.
  Screenshots pending a Chrome session.

---

## v0.9.0 — *daemon foundation* — *shipped*

The bridge release that lands the persistent local runtime without
the v2.0.0 surgery. Existing flows (`claudemesh launch`, MCP, cold
sends) keep working unchanged; opt-in by running `claudemesh daemon
up` and the rest of the CLI starts routing through the local socket.

- **`claudemesh daemon up`** — long-lived process holding one broker
  WS per attached mesh, durable outbox/inbox in SQLite, IPC over UDS
  (+ optional loopback TCP w/ bearer), SSE event stream.
- **Caller-stable idempotency** — every send carries a
  `client_message_id` and a canonical `request_fingerprint`
  (sha256 over envelope shape). Broker persists both on
  `mesh.message_queue` and echoes them on push. Receiving daemons
  dedupe their inbox by `client_message_id`.
- **§4.5.1 IPC duplicate-lookup table** — 11 cases × 5 statuses ×
  match/mismatch covered by 15 unit tests.
- **`claudemesh send` daemon routing** — daemon path tried first
  when its UDS exists; falls back to bridge / cold path otherwise.
  JSON output gains `via:"daemon"`.
- **Service install** — `daemon install-service --mesh <slug>` writes
  a launchd LaunchAgent on macOS / systemd-user unit on Linux.
  Refuses CI envs unless `--allow-ci-persistent`.
- **Outbox CLI** — `daemon outbox list [--failed|--pending|...]`,
  `daemon outbox requeue <id>`. Atomic abort+insert with
  `superseded_by` chain on requeue.
- **Host-fingerprint pin** — `daemon accept-host` records a
  sha256(machine-id || first-stable-mac) on first run; later restarts
  refuse if the fingerprint shifts (accidental-clone detection).
- **Sprint 7 deferred** — broker-side dedupe enforcement (partial
  unique index on `(mesh_id, client_message_id)`,
  `mesh.client_message_dedupe` atomic-accept table) intentionally
  postponed; tracked at `.artifacts/shipped/2026-05-03-daemon-spec-
  broker-hardening-followups.md`.

Locked spec: `.artifacts/shipped/2026-05-03-daemon-spec-v0.9.0.md`.

---

## v0.9.x — *daemon promotion: required + thin MCP* — *shipped*

The v0.9.0 foundation got promoted in three quick releases:

- **1.24.0** — daemon required for in-Claude-Code use. MCP server
  shrinks from 979 to ~200 LoC of push-pipe (rest is the unrelated
  mesh-service proxy mode). `claudemesh install` auto-installs and
  starts the daemon service. `claudemesh launch` ensures daemon is
  running before spawning Claude.
- **1.25.0** — Sprint 4 outbound routing fix. Daemon was sending
  every outbox row as broadcast (`*`); now resolves and encrypts at
  IPC accept time, drain is a forwarder. Adds `mesh`, `target_spec`,
  `nonce`, `ciphertext`, `priority` columns to the outbox.
- **1.25.0** — CLI thin-client routing for `peer list`,
  `skill list`, `skill get`.
- **1.25.0** — ambient mode: raw `claude` Just Works after
  `claudemesh install`.

What this leaves on the v2.0.0 redesign is documented at
`.artifacts/specs/2026-05-04-v2-roadmap-completion.md`.

---

## v1.26.0 → v1.30.0 — *Sprint A toward v2* — *shipped*

The Sprint A push completed everything spec'd for v2.0.0 *except* HKDF
identity (deferred for security review).

- **1.26.0** — multi-mesh daemon. One process attaches to every joined
  workspace simultaneously. Aggregate read routes (`/v1/peers`,
  `/v1/skills`) tag each record with its mesh; explicit `?mesh=<slug>`
  narrows server-side. Outbox dispatch picks the right broker via the
  `mesh` column.
- **1.27.0** — thin-client expansion to state + memory. `state get`,
  `state set`, `state list`, `remember`, `recall`, `forget` all route
  through `/v1/state` and `/v1/memory`. First teaser of the
  `claudemesh workspace <verb>` alias surface.
- **1.27.1** — wired six previously-dead launch flags through the CLI
  entrypoint (`--role`, `--groups`, `--message-mode`, `--system-prompt`,
  `--continue`, `--quiet`). Pure plumbing fix.
- **1.27.2** — bundled `SKILL.md` gains a canonical fully-populated
  spawn template + per-flag annotation table for unattended scripting.
- **1.27.3** — self-healing daemon lifecycle. Every CLI verb probes
  `/v1/version` (no more stale-socket false positives), auto-spawns a
  detached `daemon up` under a file-lock when down, polls until live.
  30 s recently-failed marker prevents thundering-herd retries.
- **1.28.0** — bridge tier deletion (~600 LoC dead code removed) +
  per-process daemon policy: `--strict` (refuse cold fallback) and
  `--no-daemon` (skip daemon entirely). Single chokepoint at
  `withMesh`. Env equivalents.
- **1.29.0** — per-session IPC tokens. Every `claudemesh launch` mints
  a 32-byte token under tmpdir mode-0600, registers it with the
  daemon, exposes the path via `CLAUDEMESH_IPC_TOKEN_FILE` to children.
  Daemon resolves `Authorization: ClaudeMesh-Session <hex>` to a
  `SessionInfo`. CLI invocations from inside a launched session
  auto-scope to its workspace instead of aggregating across all
  joined meshes (verified: `peer list` returns 1 workspace's peers
  with token, all 3 without). Server-side `meshFromCtx()` plumbing
  on every read route.
- **1.30.0** — per-session broker presence. Two `claudemesh launch`
  sessions in the same cwd finally see each other in `peer list`. Each
  launched session has a long-lived broker presence row owned by the
  daemon, identified by a per-launch ephemeral keypair vouched by the
  member's stable key (OAuth-refresh-vs-access shape). Broker gains a
  `session_hello` handler with parent-attestation TTL ≤24h + session-
  signature checks; daemon adds a slim `SessionBrokerClient` and
  registry lifecycle hooks. Also fixes a latent 1.29.0 TDZ bug where
  `claudemesh launch`'s IPC session-token registration was silently
  failing every run. Side-cleanup: 87 accumulated TS errors (77 broker,
  10 CLI) paid down to zero. *Shipped 2026-05-04 in CLI v1.30.0.*
  Spec at `.artifacts/specs/2026-05-04-per-session-presence.md`.

What's left for true v2.0.0 (next sessions):

- **1.31.0** — launch wizard refactor (single render loop, daemon-as-
  step probe panel, last-used persistence, drop `@ts-nocheck`).
- **1.32.0** — setup wizard refactor (state-detection snapshot, four-
  branch flow, daemon install offer, post-join panel).
- **1.33.0** — full mesh→workspace public-surface rename in help/docs/
  site; mesh aliases tagged deprecated; protocol/DB stay `mesh_*`.

---

## v1.31.0 → v1.32.0 — *multi-session UX bundle* — *shipped*

The Sprint B push that made multiple Claude Code sessions on the
same daemon actually pleasant — self-identity via session pubkey,
`--self` fan-out, broker welcome.

- **1.31.x** — peer list shows `profile.role` and groups; resolves
  hex prefixes to full pubkeys before send; clean rebuild path with
  correct VERSION baked in.
- **1.32.0** — multi-session UX bundle (self-identity, `--self`
  fan-out, broker welcome). *Shipped 2026-05-04 in CLI v1.32.0.*

---

## v1.34.x — *multi-session correctness train* — *shipped*

The 2026-05-04 ship train — seven releases over a few hours that
took claudemesh from "works for one session" to "internally
consistent for N sessions on one daemon." Every layer that was
shared between sessions either grew per-recipient scoping or
demuxed at its boundary.

The throughline: any time the daemon held shared state — bus,
inbox, broker fan-out — two sessions belonging to the same member
silently saw each other's traffic. Each release fixed one layer,
each release exposed the next gap.

- **1.34.7 — inbox flush + delete commands.** First-class CLI
  cleanup for the persisted inbox; previously you had to drop into
  raw `sqlite3`. `claudemesh inbox flush --mesh|--before|--all`
  with `--all` confirmation guard, plus `claudemesh inbox delete
  <id>`. *Shipped 2026-05-04.*
- **1.34.8 — read-state + TTL prune + first echo guard.** New
  `seen_at` column on `inbox`; live channel emits + interactive
  listings flip it; welcome filters on `seen_at IS NULL` instead
  of an arbitrary 24h window. Hourly prune deletes rows older than
  30 days. First attempt at a self-echo guard at the WS boundary
  (later proven incomplete in 1.34.13). *Shipped 2026-05-04.*
- **1.34.9 — broader echo guard + system event polish.** Daemon-WS
  guard relaxed (1.34.8 required both axes; session-attributed
  echoes carry session pubkey on `senderPubkey` so the strict
  filter never triggered). Session-WS skips system events to dedupe
  peer_join broadcasts. Richer peer-join channel render
  (pubkey prefix + groups + last-seen for `peer_returned`).
  Daemon-staleness warning when CLI ≠ running daemon version.
  *Shipped 2026-05-04.*
- **1.34.10 — per-session SSE demux + universal daemon.** The
  bus stays single-shot; demux happens at the SSE bind layer
  via `SseFilterOptions`. Each subscriber's session token resolves
  server-side to a session pubkey + member pubkey, and
  `shouldDeliver` filters on `recipient_pubkey` + `recipient_kind`.
  Also: `daemon up` and `install-service` deprecate `--mesh` /
  `--name` (universal daemon attaches to every joined mesh
  automatically); `daemon_started` boot log stamps the version.
  *Shipped 2026-05-04.*
- **1.34.11 — inbox per-recipient column.** Storage half of
  1.34.10. New `recipient_pubkey` + `recipient_kind` columns on
  `inbox` (indexed, non-destructive migration; legacy rows land
  NULL and stay visible to everyone). `listInbox` accepts
  `recipientPubkey` + `recipientMemberPubkey`; `/v1/inbox`
  resolves them from the session token. Welcome auto-fixes —
  it already passed the token. *Shipped 2026-05-04.*
- **1.34.12 — `daemon up` detaches by default.** Pre-1.34.12
  ran in foreground and streamed JSON logs to the terminal until
  Ctrl-C. Now spawns a detached child re-execing `daemon up
  --foreground` with stdout/stderr → `~/.claudemesh/daemon/
  daemon.log`; parent exits cleanly with pid + log path.
  Service units (launchd plist, systemd-user) explicitly pass
  `--foreground` so the service manager owns lifecycle.
  *Shipped 2026-05-04.*
- **1.34.13 — MCP forwards session token on `/v1/events`.** The
  actual fix that activated 1.34.10's demux. The MCP server's
  SSE subscription wasn't sending the session token, so the
  daemon's `/v1/events` resolved `session` to null and the demux
  filter was empty — every MCP received the unfiltered global
  stream. `subscribeEvents` now passes `Authorization:
  ClaudeMesh-Session <token>`. *Shipped 2026-05-04.*

### Architecture invariant after 1.34.13

Every shared store / channel on the daemon now scopes by recipient.
Single bus + single tables remain canonical; demux is isolated to
one chokepoint per layer.

| Layer | Scoping mechanism | Shipped |
|---|---|---|
| EventBus | SSE demux at bind layer + token forwarding | 1.34.10 + 1.34.13 |
| inbox.db | `recipient_pubkey` / `recipient_kind` columns | 1.34.11 |
| outbox.db | `sender_session_pubkey` for routing | 1.34.0 |

### Known gaps — status after the 2026-05-04 follow-up sprint

Three of the four 1.34.x triage gaps shipped in 1.34.14 + 1.34.15
(2026-05-04). Gap #4 is spec'd and queued.

- ✅ **Stale `CLAUDEMESH_CONFIG_DIR` falls back** *(1.34.14)*. The
  env var no longer silently breaks subsequent CLI calls. When the
  inherited path points at a tmpdir that no longer exists,
  `paths.ts` warns once on stderr (TTY-only) with a shell-specific
  unset hint and falls back to `~/.claudemesh`. The dir-existence
  check (not `config.json`) keeps fresh-launch first-write working.
- ✅ **`peer list --mesh <slug>` actually scopes** *(1.34.15)*.
  Diagnosis from the original triage was wrong — broker has been
  scoping correctly since 1.26.0 via `conn.meshId`. Bug was CLI-
  side: `tryListPeersViaDaemon()` was called with no argument in
  `commands/peers.ts:140` and `commands/launch.ts:407`. Both now
  forward the slug as `?mesh=<slug>`. `send.ts` cross-mesh hex-
  prefix resolution intentionally untouched.
- ✅ **`kick` refuses no-op kicks on control-plane** *(1.34.15)*.
  Broker now skips peers where `peerRole === "control-plane"` and
  surfaces them in a new additive ack field
  `skipped_control_plane`; CLI reads it and points the user at
  `ban` (remove member) or `daemon down` (take a daemon offline
  locally). Soft `disconnect` keeps old behavior — useful when
  intentionally nudging a control-plane peer to re-authenticate.
  `PeerConn` gains a `peerRole` slot populated at both
  `connections.set` sites. The richer `presence pause [--mesh X]`
  verb (option (b) from the triage) deferred as its own feature.
- 📋 **Session capabilities — spec only**. Launched sessions still
  inherit all member grants transitively. Spec at
  `.artifacts/specs/2026-05-04-session-capabilities.md` covers a v2
  parent attestation alongside v1 with an `allowed_caps[]` subset,
  broker enforcement as `intersection(member.peerGrants, session.
  allowed_caps)`, and a bonus `state-write` cap to close the "any
  session can clobber shared keys like `current-pr`" footgun.
  Default when no caps subset is declared = full member set
  (today's behavior; opt-in restriction). Ships behind a 1-week
  dry-run window before flipping enforcement, mirroring the
  original per-peer-capabilities rollout. ~1 sprint of focused
  work; queued behind v0.3.0 topic-encryption.

---

## v1.34.16 + broker — *continuous presence* — *shipped*

User report on 2026-05-05: `claudemesh peer list` returned zero
peers despite running sessions. Diagnosis: half-dead WS connections
that NAT/CGNAT silently dropped, with no application-layer staleness
detection on either side. Linux TCP keepalive default ≈ 2hrs idle
+ 11min probes — sessions stayed zombie for hours before the kernel
RST'd the socket and the daemon's existing close-handler reconnect
fired.

Two layers shipped together:

- **Liveness watchdogs** *(broker + CLI 1.34.16)*. Both sides now
  detect stalled WS in 75s instead of waiting for the kernel.
  - Broker: `PeerConn.lastPongAt` bumped on every `pong`. The 30s
    ping loop also calls `ws.terminate()` on conns whose pong is
    >75s stale, firing the close handler → existing peer_left
    cleanup.
  - Daemon: `ws-lifecycle.ts` adds an idle watchdog at 30s cadence,
    started after hello-ack. Bumps `lastActivity` on incoming
    message + ping + pong frames. Sends its own `sock.ping()` if
    activity is recent, `sock.terminate()` if idle >75s. Watchdog
    cleared on close + explicit close().
  - 100x improvement on detection time (2hrs → 75s).
- **Lease model** *(broker only, no protocol change)*. Peers no
  longer see `peer_left`/`peer_joined` for transient reconnects.
  - `PeerConn` gains `leaseState` ("online"|"offline"), `leaseUntil`,
    `evictionTimer`. On WS close, the conn enters **offline-leased**
    state for 90s instead of immediate cleanup.
  - `handleHello` and `handleSessionHello` check for an offline-
    leased entry matching the stable identity before running session-
    id dedup. On match: clear `evictionTimer`, swap `ws`, restore
    online state, drain queued DMs, return `silent: true`. The
    hello dispatcher skips the peer_joined broadcast.
  - `evictPresenceFully` extracted from the close handler — runs
    the peer_left broadcast + cleanup (URL watches, streams, MCP
    registry, clock auto-pause). Called by `evictionTimer` after 90s
    grace, or directly when no lease was online (defensive).
  - `broker.ts` exports `restorePresence(presenceId)` — clears
    `disconnectedAt` + bumps `lastPingAt`, called on reattach to
    undo the DB-level stale-presence sweeper if it fired during
    grace.
  - DMs sent during grace fall through to the existing message_queue
    path (sendToPeer no-ops on dead WS, queue row stays with
    deliveredAt=NULL, drained on reattach). Backward compatible
    with old daemons.

Spec at `.artifacts/specs/2026-05-05-continuous-presence.md`.
Layer 3 (resume token to skip full attestation on reconnect) deferred
— pure optimization, not needed for the user-visible "no
invisibility moment" goal.

*Shipped 2026-05-05.*

## v1.34.17 — *host fingerprint v2: stable across Mac reboots* — *shipped*

Field report 2026-05-19: after a routine Mac restart the daemon
(under 1.34.16) entered a launchd respawn loop on
`host_fingerprint mismatch` — `runs` past 360, `daemon.log` at
24 MB, the user's `claudemesh peer list` falling to the cold
path and showing zero peers.

Root cause was in `apps/cli/src/daemon/identity.ts`. v1 of the
algorithm hashed `host_id || mac` where (a) `host_id` was empty
on macOS and (b) `mac` was picked by enumerating
`os.networkInterfaces()`, ignoring a short list of known-virtual
prefixes, and taking the lex-first of the rest — usually `en0`,
the Wi-Fi adapter, whose MAC Apple's privacy feature randomizes
across reboots and network rejoins. The stored hash was anchored
to one randomized MAC; the next boot's MAC produced a different
hash; the safety check fired correctly for the wrong reason.

The fix is a hardened algorithm bumped to `schema_version: 2`:

- **macOS host_id** — `IOPlatformUUID` via `ioreg`, parsed once
  at daemon start, cached for process lifetime. Burned into
  EFI/hardware; stable across reboots and OS reinstalls.
- **MAC picker** — rejects any MAC with the locally-administered
  bit (`0x02`) set; prefers true hardware MACs and only falls
  back to locally-administered ones when no hardware NIC is
  enumerable. Interface ignore list extended with `anpi*`,
  `bridge*`, `ap[0-9]`.
- **Domain-separated hash** — v2 prepends `"v2\0"` so its hash
  can never collide with a v1 hash on the same inputs.
- **Silent migration** — existing v1 stores that still match
  under the v1 algorithm (legitimate same-host upgrades) are
  transparently rewritten as v2 with no error. v1 stores that
  fail the v1 check are reported as genuine mismatches as
  before. Unknown future schema versions return `unavailable`
  without overwriting.

18 unit tests in `apps/cli/tests/unit/identity.test.ts` cover the
pure helpers + every `checkFingerprint` branch + the v1→v2
silent-upgrade path. Two pre-existing test-infra papercuts were
fixed alongside: `turbo.json` now declares `test` depends on
`build`, and a new vitest globalSetup
(`apps/cli/tests/setup/ensure-built.ts`) rebuilds on demand with
`~/.bun/bin` layered into PATH so golden tests no longer fail
opaquely after a clean checkout.

## v2.0.0 — *HKDF cross-machine identity*

The remaining v2 promise after Sprint A: the user's account secret
derives a deterministic ed25519 keypair per workspace. Same identity
across laptop + desktop + server, no key copy ritual.

- **`HKDF(account_secret, info: "claudemesh/mesh/<mesh_id>/peer",
  salt: <user_id>)`** — derived per-workspace.
- **Broker `account_secret` distribution** — vended on first
  authenticated install over TLS. Needs design review on key
  compromise recovery story.
- **Migration** — existing keypairs in config keep working. Opt-in
  re-enrollment for users who want cross-machine sync.
- **Hello-sig protocol** — unchanged.

Reserved as its own sprint with an explicit security-review window.
Estimated 2-3 weeks.

## v0.3.0 — *the operator layer*

For teams that want to run their own broker, encrypt at the topic
level, or wire claudemesh to messaging surfaces beyond Claude Code.

- **Per-topic encryption — phase 1: notification table** — write-
  time `@-mention` fan-out via `mesh.notification`, replacing the
  regex-on-decoded-ciphertext scan. Survives the cutover to real
  ciphertext. *Shipped 2026-05-02 (migration 0025).*
- **Per-topic encryption — phase 2: schema + creator seal** —
  topics generate a 32-byte symmetric key on creation; broker
  seals via `crypto_box` for the creator. New columns:
  `topic.encrypted_key_pubkey`, `topic_message.body_version`, and a
  `topic_member_key` table for sealed per-member copies. New API:
  `GET /v1/topics/:name/key`. *Shipped 2026-05-02 (migration 0026).*
  Spec at `.artifacts/specs/2026-05-02-topic-key-onboarding.md`.
- **Per-topic encryption — phase 3 (CLI)** — pending-seals endpoint,
  seal POST, CLI `services/crypto/topic-key.ts`, `claudemesh topic
  post` for encrypted REST sends, decrypt-on-render in `topic tail`,
  30s background re-seal loop. Wire format: `<32-byte sender x25519
  pubkey> || crypto_box(topic_key)` so re-sealed copies decode like
  creator-sealed copies. *Shipped 2026-05-02 in CLI v1.8.0.*
- **Per-topic encryption — phase 3.5 (web)** — browser-side
  persistent ed25519 identity in IndexedDB +
  `POST /v1/me/peer-pubkey` sync + web chat encrypt-on-send /
  decrypt-on-render. The dashboard's throwaway pubkey is replaced on
  first chat-panel mount with one whose secret the browser actually
  holds; the existing CLI re-seal loop seals the topic key against
  it within 30s. Composer shows `🔒 v0.3.0` when keyed and "waiting
  for a CLI peer to share the topic key" while `not_sealed`.
  *Shipped 2026-05-02.*
- **v0.3.1 — topic message threading (reply-to)** — `topic_message`
  gains a self-FK `reply_to_id` column (migration 0027); REST `POST
  /v1/messages` and the WS `send` envelope accept `replyToId`; broker
  validates same-topic membership. CLI: `topic post --reply-to <id>`
  (full id or 8+ char prefix), `topic tail` renders `↳ in reply to
  <name>: "<snippet>"` above replies and emits `#xxxxxxxx` short ids
  per row for copy-paste. WS push envelope + MCP `<channel>` channel
  attributes now carry `senderMemberId`, `senderName`, `topic`,
  `message_id`, `reply_to_id` so the recipient has everything needed
  to thread a reply without a follow-up query. *Shipped 2026-05-02 in
  CLI v1.9.0.*
- **v0.4.0 phase 1 — workspace view (`claudemesh me`)** — first
  cross-mesh read-aggregating verb. `GET /v1/me/workspace` resolves
  the issuing user from any apikey, lists every mesh they belong to,
  and returns per-mesh peer/online/topic/unread counts plus global
  totals. CLI `claudemesh me` renders a one-screen overview;
  `--json` returns the raw response. Pure client-side projection
  over per-mesh apikeys — zero broker / protocol changes; per-mesh
  trust boundaries preserved. *Shipped 2026-05-02 in CLI v1.10.0.*
  Spec at `.artifacts/specs/2026-05-02-workspace-view.md`.
- **v0.4.0 phase 2 — `claudemesh me topics` + dashboard parity**
  — `GET /v1/me/topics` aggregates topics across every mesh the
  caller belongs to with per-topic unread counts and last-message
  timestamps, sorted by activity. CLI verb renders the feed with
  `--unread` filter and `--json` output. Web dashboard adds a
  matching `/dashboard/topics` page (SSR, direct DB) with a Topics
  entry in the sidebar between Meshes and Invites. *Shipped
  2026-05-03 in CLI v1.11.0.*
- **v0.4.0 phase 3 — `claudemesh me notifications` + dashboard
  parity** — `GET /v1/me/notifications` aggregates @-mention rows
  across every joined mesh in a 7-day window (`?since=ISO`
  override, `?include=all` to surface already-read). CLI verb
  prints unread feed with sender + topic + snippet (or
  `[encrypted]` for v2 ciphertext). Web dashboard adds
  `/dashboard/notifications` with a "show all" toggle, matching
  the universe page's mention card aesthetic. *Shipped 2026-05-03
  in CLI v1.12.0.*
- **v0.4.0 phase 4 — `claudemesh me activity` + dashboard
  parity** — `GET /v1/me/activity` returns recent topic messages
  across every joined mesh in a 24h default window
  (`?since=ISO`), excluding messages the caller authored
  themselves ("what's happening that I missed"). CLI verb prints
  a condensed feed; web `/dashboard/activity` clusters
  consecutive messages from the same topic into thread blocks
  with sender + relative timestamp. *Shipped 2026-05-03 in CLI
  v1.13.0.*
- **v0.4.0 phase 5 — `claudemesh me search` + dashboard parity**
  — final aggregating verb. `GET /v1/me/search?q=...&limit=N`
  matches against topic names + sender display names + v1
  message snippets (server-side base64 decode + ILIKE). v2
  messages match only on topic/sender (server doesn't hold their
  topic keys). 30-day window for messages keeps the scan
  bounded. CLI verb yellow-highlights matches inline; web
  `/dashboard/search` adds a focused search input + `<mark>`
  highlighting + 30-day scan note. *Shipped 2026-05-03 in CLI
  v1.14.0.* v0.4.0 substrate is complete — every aggregating
  read verb now has CLI + web parity.
- **v0.5.0 phase 1 — default-aggregation for `topic list` +
  `notification list`** — when no `--mesh` is passed these verbs
  now route through `/v1/me/topics` and `/v1/me/notifications`
  instead of prompting. `--mesh foo` keeps the per-mesh
  behavior. *Shipped 2026-05-03 in CLI v1.15.0.*
- **v0.5.0 phase 2 — default-aggregation for `task list`,
  `state list`, `memory recall`** — three new aggregator
  endpoints land: `/v1/me/tasks` (open + claimed by default,
  `?status=all|open|claimed|completed`), `/v1/me/state`
  (every key/value across meshes, `?key=foo` filters), and
  `/v1/me/memory?q=` (ILIKE on content + tags, no-query
  default returns last 30d). CLI: omitting `--mesh` on each
  verb routes through the matching aggregator. *Shipped
  2026-05-03 in CLI v1.16.0.*
- **v0.7.0 — collapse `mesh.name` and `mesh.slug` into one identifier** —
  pre-launch correction of a piece of generic SaaS scaffolding that
  was earning no keep here. Every visible surface (CLI picker,
  `--mesh` flag, dashboard sidebar, broker presence rows) already
  keyed on slug; `name` was a parallel string that confused users
  on rename ("I renamed it but nothing visible changed"). Now: slug
  IS the identifier. `claudemesh rename <old-slug> <new-slug>` is
  the entire rename surface — there is no separate display name.
  CLI picker drops the `(parens)`. Server `PATCH /api/cli/meshes/:slug`
  body becomes `{ slug }`; the route writes both columns to keep
  them in sync. New mesh creation derives slug from input.name and
  stores `name = slug`. The `mesh.name` DB column is kept for now
  (avoids touching ~25 reader sites in queries.ts / v1-router.ts /
  dashboard pages) and always equals slug; a follow-up migration
  drops it. The just-shipped `claudemesh slug` verb (v0.6.2) is
  removed — its semantics merge into `rename`. *Shipped 2026-05-03
  in CLI v1.21.0 + web.*
- **v0.6.2 — `claudemesh slug <old> <new>`** — change a mesh's
  URL-safe slug (the identifier the CLI picker, `--mesh` flag,
  and dashboard sidebar all key on). Slugs are NOT globally
  unique — `mesh.id` is canonical — so the route only validates
  the regex (`^[a-z0-9][a-z0-9-]{1,31}$`); it does not enforce
  cross-user uniqueness. The CLI does refuse a local collision
  (two joined meshes with the same slug would make the picker
  ambiguous). On success, local config rewrites the slug in
  place; other peers heal on next `claudemesh sync`. Server-side
  reuses the existing `PATCH /api/cli/meshes/:slug` route — body
  now accepts `{ name?, slug? }`. *Shipped 2026-05-03 in CLI
  v1.20.0 + web.*
- **v0.6.1 — `claudemesh rename` actually works** — adds the
  missing endpoint `PATCH /api/cli/meshes/:slug` on the web app.
  Lives under `/api/cli/*` (not `/api/my/*`) because the CLI's
  device-code JWT is signed with `CLI_SYNC_SECRET` and can't
  authenticate against better-auth's `enforceAuth` middleware —
  the new route validates the JWT inline using the same HMAC-SHA256
  pattern as `/api/cli-sync-token`. Owner-only (matches on
  `mesh.slug` AND `mesh.ownerUserId`). CLI calls the new path
  instead of the old `/api/my/meshes/:slug`. Closes the
  "API error 401: Unauthorized" the user hit after a successful
  `claudemesh login`. *Shipped 2026-05-03 in CLI v1.19.1 + web.*
- **v0.6.0 — `claudemesh file share / get` + same-host fast path** —
  CLI parity for the file-sharing surface that was already on the
  broker side (HTTP `/upload`, WS `get_file` / `list_files`) but
  reachable only through MCP-style docstrings that referenced
  unimplemented tools. Two new verbs:
  - `claudemesh file share <path> [--to peer] [--message "..."] [--upload]`
  - `claudemesh file get <id> [--out path]`
  When `--to <peer>` resolves to a session running on the same
  hostname, the CLI skips MinIO entirely and DMs the absolute
  filepath — receiver reads it directly off disk. Saves bandwidth
  and bucket space for the common "two Claude sessions on one
  laptop" case. Falls back to encrypted upload when the target is
  remote, when sharing with the whole mesh (no `--to`), or when
  `--upload` forces it. Cap: 50 MB on the network path (broker-
  enforced); same-host fast path has no cap (no bytes traverse).
  Routes the DM by session pubkey (not displayName) so sibling
  sessions of the same member work without tripping the v0.5.1
  self-DM guard. Updates the MCP `instructions` block to
  reference these CLI verbs instead of fictional `share_file()` /
  `get_file()` tools. *Shipped 2026-05-03 in CLI v1.19.0.*
- **v0.5.2 — `claudemesh skill` prints the bundled SKILL.md** —
  zero-install access for the protocol reference. SKILL.md is
  embedded into the CLI bundle at build time via Bun's
  text-import attribute, so `claudemesh skill` works on a
  fresh `npm i -g` or the prebuilt binary without any
  `~/.claude/skills/` setup. Pipe it: `claudemesh skill |
  claude --skill-add -`. Existing `claudemesh skill <list|get|
  remove>` subcommands (mesh-shared skills) preserved. *Shipped
  2026-05-03 in CLI v1.18.0.*
- **v0.5.1 — peer list self-marking + send self-DM guard** —
  `peer list` now tags rows from the caller's own member with
  `(this session)` or `(your other session)`, so a paste from
  `peer list --json` doesn't silently target your own sibling.
  `claudemesh send` rejects targets that resolve to the
  caller's own member pubkey unless `--self` is passed. Closes
  the "DM looped back to my own inbox" footgun reported on
  v1.11.0. *Shipped 2026-05-03 in CLI v1.17.0.*
- **v0.3.2 — multi-session DM routing + broadcast self-loopback** —
  fixes two production bugs: (1) replies via `claudemesh send
  <from_id>` rejected with "no connected peer" when the sender's
  session had rotated — `from_id` now exposes the *member* pubkey
  (stable) and the broker pre-flight resolves stale session pubkeys
  to the owning member's live session; (2) broadcast / `*` /
  `@group` looped back to the sender's sibling sessions, surfacing a
  spurious decrypt-fail warning — fan-out now skips by member
  pubkey, not just per-presence. Push envelope adds
  `senderMemberPubkey` alongside `senderPubkey`. *Shipped 2026-05-02
  in CLI v1.9.1.*
- **Self-hosted broker packaging** — one-command Docker compose,
  Postgres included. The new migration runner (v1.6.x) makes this
  practical.
- **Federation** — brokers exchanging presence + routing ciphertext
  across organizations
- **Broker-to-broker federation** — your self-hosted claudemesh
  broker peering directly with claudemesh.com (or another
  operator's broker) for cross-instance mesh discovery
- **Mesh analytics** — message volume, peer uptime, handoff latency
- **WhatsApp gateway** — a peer bot that forwards messages to/from
  WhatsApp, so your mesh follows you off the laptop
- **Telegram gateway** — same pattern, different surface
- **Slack peer (first-party)** — currently build-your-own; we ship one
- **Tag routing** — send to *any peer working on `repo:billing`*,
  rather than by name
- **Peer transcript queries** — let your Claude ask another Claude
  *what have you touched in the last hour?* without a human in between
- **iOS peer app (thin)** — push + reply, same JWT identity

## v3.0.0 — *Anthropic-native channels (conditional)*

Migration target, not a planned feature — depends on Anthropic
shipping first-class agent-to-agent channels in Claude Code. When
that lands:

- **Two possible shapes**, depending on Anthropic's choice:
  - *(a)* MCP-channel notifications graduate from
    `experimental.claude/channel` to a stable API. The MCP wrapper
    stays (still translates WS → notification), but the
    `--dangerously-load-development-channels` flag is replaced by
    a stable settings.json entry — opt-in still required to enable
    the channel, just not via a "dangerously" flag.
  - *(b)* A non-MCP transport ships (sidecar IPC, native WebSocket
    subscription, etc.). The MCP wrapper from v2.0.0 disappears;
    the daemon plugs into the new transport directly. Some opt-in
    config is still required somewhere (settings.json or similar)
    so Claude Code knows to subscribe.
- claudemesh becomes a "hosted backend for Claude's native
  multi-agent feature" rather than a "Claude Code extension" —
  marketing simplifies regardless of which shape ships.
- The `experimental.`/`dangerously-` framing disappears either
  way — that's the load-bearing user-facing change.

Until then, v2.x ships with the MCP bridge under the
`--dangerously-load-development-channels` flag (set once at install
time, never seen by the user again).

## Openness

- **MIT-licensed** — the protocol, the CLI, the broker, the
  marketing site
- **Reference implementation** — [claude-intercom](https://github.com/alezmad/claude-intercom)
  is the local OSS ancestor (sockets on one machine). claudemesh is
  the hosted/enterprise extension.
- **Spec-first** — the wire protocol + crypto are documented in
  [`docs/protocol.md`](./protocol.md). Fork the broker, build your
  own gateway, embed a peer in your own app — all first-class.
