The heartbeat no longer counts time the process did not run (a laptop's sleep, a blocked event loop) as silence: after such a pause each open link pings at once and closes only if its peer stays silent for close - ping.
A running worker's lost link is now a stop instead of a failure: worker_link_lost is reported and the held route starts a new worker. A second lost link within a minute of the last recovery still fails the address.
A second Ctrl+C or SIGHUP killed the server without its exit hooks, leaving the macOS lock socket file behind; the next start then refused with a stale lock. A close that does not finish within 8 s now exits too.
A manager on the p2 server owns every MCP connection and process. Session
workers hold one view each and lease the locations their conversations
work at; the manager runs the owner's mcp.json servers there (stdio per
session and location, or shared; HTTP shared by default) and offers their
tools as deferred Durable tools found through tool_search.
Stdio servers on an environment start through its pi-env daemon, one
connection per environment shared by its instances, through cmd.exe on
Windows. A project's .pi/mcp.json, read by the worker at each location,
may add stdio servers that run there and switch the owner's servers on or
off; the manager refuses everything else. A lease gets servers only on
environments its session works on.
p2 (Pi Mobile on Chord v2) moves from pi-private into pi as one commit. Root scripts that loop all workspaces
use --if-present; npm test, ./test.sh and the release script cover packages/* only (p2: cd apps/p2 && npm test);
sync-versions also updates apps' workspace pins.
