charset=UTF-8 Content-Transfer-Encoding: 8bit Webhook-in (GET verification handshake + POSTed messages), Graph-API-out for replies. Decouples reply routing from Start-driven channels via a small replySender interface, so WhatsApp registers its Send without pretending to be a long-poll channel. Stays inert until whatsapp.active is set in gateway.yaml — Meta business verification is an external account state, so activation is a manual switch.

charset=UTF-8 Content-Transfer-Encoding: 8bit The gateway ran arbitrary agent tasks in Auto mode for anyone who could message the bot. Both Hermes and OpenClaw gate every channel with an allow-list; so do we now. Config is restructured to a channels. object (matching both, and the import target) holding each channel's settings plus allow_from. The router drops any chat message whose principal isn't allow-listed — default-deny, with a global allow_all escape hatch and a per-inbound Trusted bypass for signature-verified webhooks (GitHub).

Match the established convention (Hermes and OpenClaw both default require-mention in groups on all three): a direct message always triggers, but in a group the bot acts only when addressed. Each adapter learns its own identity (Telegram getMe, Discord State.User, Slack auth.test) and detects addressing structurally — Telegram message entities + reply-to-bot (UTF-16-correct offsets), Discord mentions array + reply-to-bot, Slack <@BOTID>. The router drops a non-direct, non-mentioned message unless channels.. respond_to_all is set. WhatsApp Cloud messages are 1:1 so they count as direct.

A worker drains the inbox — replaying anything a crash left pending — and runs each as an agent job, marking it done only after the job COMPLETES. So a redelivery or restart never re-runs a finished job (the inbox (channel,message_id) key is the dedup), and a crash can at worst re-run an interrupted one: at-least-once, not the lost-or-duplicated delivery Codex flagged. Gateway activity is logged to the MAIN event store — gateway_message_received / job_spawned / result_posted / message_dropped / unauthorized, with channel, conversation, principal_id, message_id, job_id — so it's visible to memcode. Per the objective doctrine, an inbound chat message is NOT turned into an objective. Replaces the in-memory dedup + channel with the inbox; the dispatcher is now a generic per-key serial executor. --- cmd/gateway.go | 2 +- internal/channels/channels.go | 22 +- internal/channels/discord/discord.go | 9 +- internal/channels/slack/slack.go | 23 +- internal/channels/telegram/telegram.go | 19 +- internal/channels/telegram/telegram_test.go | 7 +- internal/events/events.go | 11 + internal/gateway/server/dispatch.go | 65 ++--- internal/gateway/server/dispatch_test.go | 74 +++-- internal/gateway/server/server.go | 307 +++++++++++++------- internal/gateway/state/state.go | 123 +++++--- internal/gateway/state/state_test.go | 89 +++--- internal/triggers/github/github.go | 11 +- internal/triggers/github/github_test.go | 34 ++- internal/triggers/whatsapp/whatsapp.go | 8 +- internal/triggers/whatsapp/whatsapp_test.go | 33 ++- 16 files changed, 505 insertions(+), 332 deletions(-) diff --git a/cmd/gateway.go b/cmd/gateway.go index 2fc4576..e314f10 100644 --- a/cmd/gateway.go +++ b/cmd/gateway.go @@ -48,7 +48,7 @@ result is posted back to the channel it came from.

Runtime change is minimal and behavior-preserving: a caller can pin a session id (SetSessionID), which StartChat honors verbatim; every existing caller still mints fresh (a leftover sessionID between two chats on one Session is unaffected). jobs.Spawn gains a session arg (empty for TUI/background jobs). --- cmd/agent.go | 26 ++++++++++++++++++++++- internal/agent/runtime/chat.go | 9 +++++++- internal/agent/runtime/exec.go | 4 ++-- internal/agent/runtime/runtime.go | 8 +++++++ internal/gateway/server/scheduler_test.go | 13 ++++++++++++ internal/gateway/server/server.go | 16 +++++++++++++- internal/jobs/jobs.go | 5 ++++- internal/jobs/jobs_test.go | 2 +- internal/vxui/dispatch.go | 2 +- 9 files changed, 77 insertions(+), 8 deletions(-) diff --git a/cmd/agent.go b/cmd/agent.go index 4cfbba1..cc62c45 100644 --- a/cmd/agent.go +++ b/cmd/agent.go @@ -105,7 +105,7 @@ for local gateway development.

Memory did not exist as a first-class store at all — learned facts were per-project only, so nothing the agent knew about the user travelled between repos. Add memory.md as the facts counterpart to MEMCODE.md's rules: global ~/.memcode/memory.md AND project .memcode/memory.md, additive (a global fact travels across projects, a project fact stays put), loaded once per session and injected every turn alongside instructions.

That is not how OpenClaw and Hermes behave: their memory is global and actually loaded. So do it properly. Their memory is markdown, not an opaque DB, so it can be read and used: - OpenClaw: workspace MEMORY.md, USER.md, SOUL.md, AGENTS.md, and the daily memory/*.md files, searched across the configured workspace and OpenClaw's renamed variants (workspace-main, workspace-assistant). - Hermes: ~/.hermes/memories/*.md, entries delimited by bare § lines. Port Hermes's own extractor (openclaw_to_hermes.py extract_markdown_entries): each bullet and paragraph becomes an entry prefixed with its heading context, fenced code blocks and table rows are dropped, entries are deduped by whitespace-normalized text and capped to a 20k budget. The result is written into global ~/.memcode/memory.md as a bounded, marker-delimited block that a re-run replaces in place, so migrated memory is loaded into every session the way it was in the source assistant. --- cmd/migrate.go | 415 ++++++++++++++++++++++++++++++++++++++------ cmd/migrate_test.go | 135 ++++++++++++-- 2 files changed, 484 insertions(+), 66 deletions(-) diff --git a/cmd/migrate.go b/cmd/migrate.go index 55baa1a..19108ea 100644 --- a/cmd/migrate.go +++ b/cmd/migrate.go @@ -1,11 +1,14 @@ package cmd import ( + "encoding/json" "fmt" "io" "os" "path/filepath" + "regexp" "sort" + "strconv" "strings" "github.com/spf13/cobra" @@ -54,8 +57,7 @@ state lives in a non-standard directory: slug: "openclaw", dir: dir, channels: openClawChannels, - // OpenClaw keeps its conversation/memory store under state/. - memoryArtifacts: []string{"state", "openclaw.sqlite", "memory"}, + memory: openClawMemory, }) }, } @@ -87,8 +89,7 @@ state lives in a non-standard directory: slug: "hermes", dir: dir, channels: hermesChannels, - // Hermes keeps sessions/history in state.db and sessions/. - memoryArtifacts: []string{"state.db", "sessions", "memory"}, + memory: hermesMemory, }) }, } @@ -97,11 +98,11 @@ state lives in a non-standard directory: // config (with the .env beside it resolving credential references) into the // channel/secret mapping; the rest is common across sources. type migrationSource struct { - display string - slug string - dir string - channels func(dir string, env map[string]string) (importer.Result, error) - memoryArtifacts []string // paths under dir holding the memory/history store + display string + slug string + dir string + channels func(dir string, env map[string]string) (importer.Result, error) + memory func(dir string) []string // extracts the source's memory as discrete entries } // runMigration performs the full migration for a source: channels, provider API @@ -160,8 +161,8 @@ func runMigration(cmd *cobra.Command, src migrationSource) error { skills, skillNotes := copySkills(filepath.Join(src.dir, "skills")) res.Notes = append(res.Notes, skillNotes...) - // 4.

Split the flow: a finished job moves pending -> replied with its result stored, so it is never re-run; delivery is a separate step that retries in-process and, if the channel is still down, stays queued and replays after a restart. New 'replied' inbox state + PendingReplies outbound queue. Double-processing: the only guard against running an item twice was an in-memory map, so a second 'memcode gateway' on the same repo would double every job. Take an exclusive flock on the project at startup; a second gateway is refused with a clear message. No-op on platforms without flock (the service installer is macOS/Linux only). --- internal/gateway/server/reply_test.go | 65 +++++++++++++ internal/gateway/server/server.go | 129 +++++++++++++++++++------- internal/gateway/state/lock_other.go | 14 +++ internal/gateway/state/lock_unix.go | 38 ++++++++ internal/gateway/state/state.go | 81 ++++++++++++++-- internal/gateway/state/state_test.go | 73 +++++++++++++++ 6 files changed, 358 insertions(+), 42 deletions(-) create mode 100644 internal/gateway/server/reply_test.go create mode 100644 internal/gateway/state/lock_other.go create mode 100644 internal/gateway/state/lock_unix.go diff --git a/internal/gateway/server/reply_test.go b/internal/gateway/server/reply_test.go new file mode 100644 index 0000000..e789917 --- /dev/null +++ b/internal/gateway/server/reply_test.go @@ -0,0 +1,65 @@ +package server + +import ( + "context" + "errors" + "io" + "testing" + "time" + + "github.com/memcode-ai/memcode/internal/channels" + gwconfig "github.com/memcode-ai/memcode/internal/gateway/config" + "github.com/memcode-ai/memcode/internal/gateway/state" +) + +type flakySender struct { + err error + calls int +} + +func (f *flakySender) Send(context.Context, string, channels.Outbound) error { + f.calls++ + return f.err +} + +// A finished job's reply is durable: a failing channel does not lose it or re-run +// the job.
