Scopes the lift to route prx's single-shot classifier surfaces (triage type-pass, prioritize-bulk, eval fan-outs) through the async Message Batches API for the 50% discount and a collapsed serial wall-clock, behind an explicit submit/poll lifecycle. Frames batch against prx's artifact ratchet: because the pipeline advances on signed artifacts and humans are never inside the agentic loop, non-interactive legs are already async-queue-shaped; the near-term gate is transport, not the interaction model. Interactive surfaces stay on the agent SDK. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Amt3X8s8CEdJW5civefipL

Code Coverage OverviewLanguages: TypeScript TypeScript / unitThe overall coverage remains at 88%, unchanged from the Updated |
Establishes empirically what a Claude Code on the web session can prove about itself (no TPM/SEV/IMDS root of trust; base image identifiable but not attestable) and specifies a broker protocol that gates a privileged write (e.g. filing a bead) on GitHub-verifiable proofs — branch control and private-repo read — with zero credentials in the box. Adds .claude/attest-box.sh, a git-tracked SessionStart hook that emits the attestation bundle; its bytes are pinned to the head commit the broker re-verifies, so the attestation and its producer share one anchor.

The prior commit hand-edited .claude/settings.json to add the attest-box.sh hook, but that file is generated by buildOrgHarnessSettings and drift-gated. Add the hook (and update the ordering assertion) in the builder — the source of truth — so the checked-in settings match.

The settings-builder change is repo-internal harness config, not a change to released @bounded-systems/prx behavior, so record a no-release changeset to satisfy the changeset gate.

Adds the multi-party attenuation model (a caveat chain: launch → box → artifact → broker → DoltHub, each verified by a different party — "more than the box, more than the cloud"), GitHub web-flow signing on the token's authority, passing a root of trust from the launch origin, and three concrete broker realizations (GitHub Actions + Environments, Cloudflare Worker/Tunnel, keeperd) with recommended sequencing.

Records that bd is always the writer (cloud box holds no dolt): keeperd + dolt-box, or bd → a remote dolt sql-server; never the raw DoltHub HTTP SQL API (off-model, bypasses bd's ids/events/schema). Adds the bead-write broker contract (spec-as-schema, mirroring keeperd/contract.ts) and the fail-closed keeper-side verify → bd create → signed-push pipeline reusing the prx-b44y host-backed-secret path.

Summary
Adds a proposed ADR —
docs/prx/batch-transport.md— scoping the lift to give prx the ability to use the Message Batches API.The ADR establishes that batch is a second, parallel model-call transport, not a flag on the existing path: everything prx sends today goes through
@anthropic-ai/claude-agent-sdk'squery(), whereasmessages.batches.*lives on the raw@anthropic-ai/sdk(a transitive peer dep, not a direct one). It then frames batch against prx's architecture:submit_plan→PlanArtifact,checks/v1, predicate-bundle members) and humans are never inside the agentic loop — so non-interactive legs are async-queue-shaped and the 24-hour batch window is a non-event for them.triage type-pass,triage prioritize-bulk, eval fan-outs) are the near-term win — already raw-Messages-shaped, tool-free, and running today as a synchronous sequential loop that batch replaces at 50% cost.session open,--interactive) stay onquery()unconditionally.Docs are generated from the project graph, so the new ADR is auto-discovered;
