miki-moni-dev-locate-code

name	miki-moni-dev-locate-code
description	Use when working in the miki-moni / cc-hub repo and need to find which file handles a feature (pairing, image rendering, permission mode, transcript bubbles, dashboard UI, phone client, worker relay, etc.) without re-scanning the codebase. Trigger phrases include "miki where is X", "需要修 X 在哪", "找 pair flow", "image bubble code", "permission mode chip 在哪".

Miki-Moni Code Map

Navigation reference for the miki-moni codebase (a.k.a. cc-hub). Each row points at the file + function where a feature lives, so future Codex can jump straight in instead of grepping from zero.

Architecture in one glance

PS hooks ──POST /event──▶  daemon (src/, 127.0.0.1:8765)  ──WS /ws──▶  web (web/ dashboard SPA)
                                │                          ──WS /ws_ext──▶  miki-helper VSCode extension
                                └─encrypted envelope──▶ worker (Cloudflare DurableObject) ──▶ web-phone (Pages-hosted PWA)

Layer	Path	Entry
Daemon	src/	src/index.ts (bootstraps express on 8765)
Wrapped CLI	src/cli/wrap.ts	spawned per session by miki Codex
Dashboard SPA	web/app.tsx	single big file, mounted by web/main.tsx
Phone PWA	web-phone/main-tunnel.tsx	bootstraps tunnel + dynamic-imports web/app.tsx
Cloudflare Worker	worker/src/	index.ts routes, DOs in daemon-relay.ts + pairing-coordinator.ts
CLI	bin/miki.js → src/cli/miki.ts	subcommands: start setup pair Codex install-hooks

Where things live

Pairing & relay

Task	File:Function	Notes
Generate pair QR / token	src/pairing.ts:generateNewPairingToken + pairingQrPayload	rejection sampling for entropy; strips /v1/daemon suffix
Daemon-side relay client	src/relay-client.ts:RelayClient	handlePairOffer (line ~190), handleEnvelope (line ~296), promptForPairApproval
pnpm pair --new/--rotate/--list/--show	src/cli/pair.ts	cmdNew cmdRotate cmdRevoke printQrAndCode
Worker entry routes	worker/src/index.ts	/v1/daemon /v1/phone /v1/pairing/revoke /v1/health
Worker DO: token registry	worker/src/pairing-coordinator.ts	register claim revoke + alarm sweep
Worker DO: per-daemon relay	worker/src/daemon-relay.ts	acceptPhone acceptDaemon handlePhoneMessage verifyReconnectSig
Phone-side pair handshake	web-phone/relay.ts:performPairing	verifies daemon pubkey from QR &k=
Phone bootstrap (URL hash vs cached state)	web-phone/main-tunnel.tsx:Bootstrap	URL hash always wins; initialStateRef avoids stale closure

Dashboard UI (web/app.tsx is one big file — search by function name)

Task	Function in web/app.tsx
Session card list (small cards)	Card, SessionGrid
Big "modal" card opened by clicking session	CellModal
Transcript turn rendering (text + image bubble)	TurnView (~line 666)
Image attachment strip in composer	AttachedImageStrip (~line 556)
Composer input box (Ctrl+V paste)	composer inside Card (~line 1170) + modal version (~line 2711)
Permission mode chip + dropdown	PermissionModeChip (~line 1627)
Model chip + dropdown	ModelChip (~line 1751)
AskUserQuestion modal (multi-question)	AskQuestionModal (~line 427)
WS connection / event handlers	search connectWs (~line 3641)

Daemon HTTP/WS

Route	File:Handler
/event (hook intake)	src/server.ts
/send (push prompt to wrapped Codex)	src/server.ts:558 — wrap-push fast path + VSCode prefill fallback
/sessions/previews /sessions/:uuid/transcript	src/server.ts, reads via src/session-resolver.ts:readTranscriptTail
/admin/restart /admin/quit /admin/pid	src/server.ts
/wrap/start /wrap/permission-mode /wrap/model	src/server.ts
/ws (dashboard WS) /ws_ext (helper ext WS)	src/server.ts:createApp
DNS-rebind guard	src/server.ts middleware right after express.json (line ~64)

Hooks (Codex → daemon)

Hook	File
SessionStart / Stop / UserPromptSubmit / PreToolUse / PostToolUse	hooks/miki-emit.ps1 (Windows PowerShell)
Install hooks into ~/.Codex/settings.json	pnpm install:hooks → src/cli/install-hooks.ts

Storage

What	Where
~/.miki-moni/config.json	src/config.ts (loadOrInitConfig, addPairedPeer, touchPeerLastSeen)
~/.miki-moni/miki-moni.log	pino logs
~/.miki-moni/wizard-local-only (sentinel)	written by src/cli/setup-wizard.ts:markLocalOnly
Per-session JSONL transcripts	~/.Codex/projects/<encoded-cwd>/<uuid>.jsonl (Codex Agent SDK manages)
PORT_FILE	~/.miki-moni/port — singleton guard reads it before bind

i18n

Layer	File
Master strings (en/zh-TW/zh-CN)	shared/i18n.ts
CLI banner strings	src/cli/i18n-cli.ts
Calls t("namespace.key") everywhere	grep t\(

Build / dev commands

Goal	Command
Daemon only	pnpm start (no watch) or pnpm dev (tsx watch)
Build dashboard SPA	pnpm build:web → dist/web/
Build phone PWA	pnpm build:phone → dist/web-phone/
Build both	pnpm build:all (uses && — PowerShell 5.1 will break it, run each separately on Windows)
Tests	pnpm test (vitest); pnpm vitest run tests/<one>.test.ts for single
Typecheck	pnpm typecheck
Full E2E with mock relay	pnpm verify
Daemon + mock-worker + web + phone all dev	pnpm dev:all
Pair tools	pnpm pair --new --worker-url=... / --rotate / --list / --show

Critical pitfalls (don't repeat history)

1. paired_peers.length > 0 gate on relay startup — chicken-and-egg, fixed in 0.3.7 (src/index.ts:157). If you ever re-gate this, first-pair breaks.
2. localStorage > URL hash in phone bootstrap — silent fallback, fixed in 0.3.6 (web-phone/main-tunnel.tsx). URL hash MUST win.
3. worker_url with /v1/daemon baked in — phone naively appends /v1/phone → broken path. QR generator + phone client both strip; never embed verbatim.
4. Express app.use middleware before routes — DNS-rebind guard MUST sit before any route registration in createApp.
5. /admin/restart already respawns — don't ALSO spawnDetachedDaemon in cmdRotate. Two daemons race for 8765.
6. config.json last_seen_at was historically never written — keep touchPeerLastSeen wired into RelayClient.handleEnvelope or pruning logic breaks.
7. PowerShell 5.1 doesn't support && — chain with ; or if ($?) { ... }. Affects pnpm build:all and any pasted multi-cmd.
8. Don't pollute test config into ~/.miki-moni/config.json — pnpm verify writes device.name: test. Check before pushing if you ran tests.
