* perf(claude): scan transcripts incrementally

The claude session scanner re-read the entire transcript JSONL on every
scan, so the cost of each poll grew with the length of the conversation.
Track a byte offset per file instead and parse only the bytes appended
since the previous scan.

A trailing partial line — a write still in progress — is held back until
its newline arrives. A file that shrank resets the cursor to 0; the base
scanner's uuid dedup absorbs the re-sent events. A read that fails
returns no events and leaves the cursor where it was, so a transient
error is retried on the next scan rather than skipping content.

The codex scanner received this in #1031; this extends the same
improvement to the claude scanner. readSessionLog is exported for tests,
mirroring readTranscriptRange there.

* fix(claude): forward a complete final record with no trailing newline

The incremental reader consumed only through the last newline, so a final
JSONL record flushed without its terminating newline — at shutdown or on
import — was held back as if it were a partial write and never forwarded
until a later append supplied the newline. The previous whole-file reader
parsed such a record.

Consume a trailing segment when it already parses as a complete JSON value,
and keep holding back a genuinely partial line (which parses as incomplete).

HAPI

Run official Claude Code / Codex / Cursor Agent / Grok Build / OpenCode sessions locally and control them remotely through a Web / PWA / Telegram Mini App.

Why HAPI? HAPI is a local-first alternative to Happy. See Why Not Happy? for the key differences.

Features

  • Seamless Handoff - Work locally, switch to remote when needed, switch back anytime. No context loss, no session restart.
  • Native First - HAPI wraps your AI agent instead of replacing it. Same terminal, same experience, same muscle memory.
  • AFK Without Stopping - Step away from your desk? Approve AI requests from your phone with one tap.
  • Your AI, Your Choice - Claude Code, Codex, Cursor Agent, Grok Build, OpenCode—different agents, one unified workflow.
  • Terminal Anywhere - Run commands from your phone or browser, directly connected to the working machine.
  • Voice Control - Talk to your AI agent hands-free using the built-in voice assistant.
  • Workspace Browser - Opt-in via one or more hapi runner start --workspace-root <path> flags: browse scoped file trees from the web and start sessions in allowed subdirectories.

Getting Started

npx @twsxtd/hapi hub --relay     # start hub with E2E encrypted relay
npx @twsxtd/hapi                 # run claude code

hapi server remains supported as an alias.

The terminal will display a URL and QR code. Scan the QR code with your phone or open the URL to access.

The relay uses WireGuard + TLS for end-to-end encryption. Your data is encrypted from your device to your machine.

For self-hosted options (Cloudflare Tunnel, Tailscale), see Installation
