Phase 2 of live app annotation: full parity on Pi over one shared
implementation instead of drifting copies.
- Extract every proxy decision into packages/shared/live-proxy-core.ts
(HTML injector state machine, loopback/Host/Origin predicates,
CSP/X-Frame-Options policy, redirect rewrite, WS origin gate, bridge
assembly, liveAppDraftIdentity) and the CLI probe + live-mode messages
into packages/shared/live-probe.ts. packages/server/live-proxy.ts is
now a thin Bun transport over the core; its test suite passes
unmodified.
- Add packages/shared/live-proxy-node.ts, the node:http transport the Pi
extension runs: streaming request/response piping through the shared
injector, and WebSocket (HMR) passthrough that replays the client's
handshake upstream over raw TCP and pipes the sockets byte-for-byte.
Transport tests run the proxy in a real node child process, because
Bun's node:http shim drops writes to an upgrade event's socket.
- Wire Pi: /plannotator-annotate probes loopback URLs live-first with
the shared probe (same 3s timeout, same <500 gate, same messages),
recognizes --app/--static via parseAnnotateArgs's liveFlags opt-in
(OpenCode deliberately does not opt in), and serves mode annotate-app
from serverAnnotate.ts with the shared per-target draft identity,
live sessions excluded from history/submissions, the remote hard-off
throw, and guarded live-proxy shutdown.
- Vendor live-proxy-core/live-probe/live-proxy-node plus the
dependency-free bridge-script constants to generated/.
