fc8c32e07a fix: reliable generated-image display + stop client remount storm (#927) (#934)
* test: reproduce issue #927

* fix(hub): cache generated images + raise socket buffer cap (closes #927)

Generated-image display was slow and could silently fail:

- The /generated-images route sent `Cache-Control: no-store`, so every
  card remount (session switch, scroll, reload) re-ran the full HTTP ->
  socket.io RPC -> base64 round-trip. The bytes for an imageId are
  immutable, so serve them `private, max-age=31536000, immutable` + ETag.
- socket.io / bun-engine `maxHttpBufferSize` was left at the 1 MB default,
  while the MCP tool accepts images up to 25 MB. The base64 CLI -> hub ack
  frame for anything above ~750 KB raw exceeded the cap and was dropped.
  Raise the buffer to comfortably carry the largest allowed image.

* fix(hub): short-circuit generated-image revalidation with a 304 (#927)

The imageId is an immutable content fingerprint, so use it as the ETag and
answer If-None-Match with 304 before issuing the readGeneratedImage RPC.
This makes the ETag actually useful: revalidation now skips the CLI socket
round-trip entirely, and still serves correctly even after the image was
evicted from the CLI's in-memory store.

* fix(web): stabilize ApiClient identity across token refresh (#927)

The ApiClient was rebuilt whenever the token value changed (useMemo dep),
even though every request already reads the live token via getToken/tokenRef.
On a flaky/remote connection, repeated 401s -> onUnauthorized -> forced
refresh churned `api`'s identity, which remounts everything keyed on it:
VoiceBackendSession ([props.api]) -> Voice re-register spam, and
GeneratedImageCard ([ctx.api]) -> per-image refetch storm, feeding a
render avalanche. Depend on auth presence (hasToken) instead.

Reproduced with a useAuth hook test (red->green); full web suite stays green.

HAPI

Run official Claude Code / Codex / Gemini / 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, Gemini, OpenCode—different models, 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
