Treat long-lived bridges and stores as explicit state machines

Summary#

Long-session tooling code fails at the edges: reconnects, shutdown, malformed messages, and partial cleanup are where corruption usually starts. Define strict contracts at the boundaries, reject invalid operations before mutation, and add regression tests for reconnect, shutdown, and listener-failure scenarios.

Problem#

Weak typing, silent invariant violations, and ambiguous shutdown semantics allowed dropped messages, swallowed errors, or corrupted internal state in DevTools-style bridge/store layers.

Solution#

Model lifecycle transitions explicitly, validate inbound data and store operations before applying them, preserve the first thrown error while still reporting later ones, and buffer outbound traffic until reconnect handshakes complete.

Failure Modes#

Silently continuing after invalid parent-child or reorder operations
Allowing sends after shutdown or during half-closed connections
Dropping queued messages during extension or socket reconnects
Using broad any-like types that defer contract errors until production
