feat(runtime): migrate boxd provider to SDK 0.2.x - #610
Conversation
boxd 0.2 reshaped the client: Compute/Box objects with methods became a
flat AsyncBoxd client with machines.<verb>(id, ...) namespaces and
plain-data Machine records. Migrate the runtime provider, CLI, and tests
to that surface (pin boxd>=0.2.7,<0.3).
Provider changes beyond the mechanical mapping:
- Explicit resume on warm reuse: the 0.2.x SDK never resumes a
suspended/hibernated/stopped machine implicitly, and wait_until_ready
raises on "stopped", so _resolve_vm now revives saved machines before
redeploying.
- Name-lookup fallback: machines.get(name) resolves names only in the
account's default org context; a machine living in another org raises
NotFound while list() still shows it. Deploys then died with
ConflictError and on_exit teardown silently skipped, leaving the VM
running (and billing). _get_machine now falls back to an exact-name
scan of machines.list().
- Sizing is optional: boxd machines come in fixed vCPU/memory pairs
with an org-level default, and the server refuses per-machine disk
sizing ("every machine gets 100 GiB"). RuntimeConfig defaults for
vcpu/memory/disk are now None; only explicitly-set values reach the
create call. --disk stays wired for when boxd ships disk sizing.
- Dropped the sha256-verify-and-retry upload workaround for boxd 0.1.1
truncation: 0.2.x uploads stream in chunks and return a confirmed
byte count, which the provider checks instead.
- bindu shell: the old exec(interactive=True) convenience is gone;
bridge the local terminal to a stream_exec(tty=True) session (raw
mode, stdin pump, SIGWINCH resize).
- wait_until_ready replaces the hand-rolled exec-readiness poll;
stream_logs uses stream_exec (machines.logs is the VM console, which
a detached nohup'd agent never writes to).
Verified end to end against real VMs: fresh deploy -> healthy -> A2A
card, and the full pause -> resume -> redeploy -> destroy lifecycle.

📝 WalkthroughWalkthroughThe boxd runtime now targets SDK 0.2.x. It uses machine-based execution, optional organization-default sizing, verified uploads, streaming logs, lifecycle actions, and manual TTY handling for ChangesBoxd runtime migration
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to This migration broadens machine lookup and can perform execution, resume, pause, or deletion against the first visible machine with a matching name rather than the machine originally deployed; duplicate names or cross-organization visibility could therefore affect the wrong VM. Partial failures and concurrent same-name deployments may also leave stale or interleaved runtime state, and piped shell input can hang. These merge-readiness risks should be addressed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

Forward and close piped stdin.
When stdin is not a TTY, this branch never reads stdin, calls stream.write, or calls stream.write_eof. Therefore, printf 'exit\n' | bindu shell <agent> does not deliver the command or EOF to bash and can remain blocked. Pump piped input into stream, send EOF, and drain output concurrently.
