+independent of both OpenAI and Anthropic.
+The custody trade was accepted by the owner on 2026-08-19 knowing its exact shape: Microsoft
+disclaims data handling for the Fireworks lane (data is shared between Microsoft and Fireworks
+and processed on Fireworks infrastructure inside the US data zone), and the zero-data-retention
+promise (volatile memory only, no logging by default, on the chat-completions surface) is
+Fireworks' own policy, not Microsoft's. The lane must therefore use plain chat completions
+only; the Responses API retains data for 30 days under its default store flag and is forbidden
+here.
+Billing was verified before acceptance: Fireworks pay-per-token on Foundry bills as Azure
+consumption (a feature registration, not a Marketplace SaaS purchase), is MACC-eligible, and
+Microsoft's own Startups material states startup credits apply to exactly this SKU; a small live
+spend must confirm the credit decrement before volume. Fireworks pay-per-token models can retire
+on 15 days notice, which is an accepted operational risk and one more reason the fallback below
+stays armed.
+Later the same day the owner simplified the routing: ALL crosscheck reviews route through the
+GLM lane, for codex-authored and claude-authored work alike. GLM belongs to neither author
+family, so single-family review is avoided for every author with one reviewer lane, and review
+capacity stops competing with the pi-codex subscription profiles that no-mistakes and the
+author fleet consume. The pi-codex roster (which R5 records as proven at the roster level while
+R9 still owes the live proof) is retained as a dormant fallback behind a config flip, never
+deleted; every review must name the lane that produced it, and a status read must show whether
+GLM is serving or the fallback is active, so a silent fallback is impossible.
+Fallback operation is a recorded degradation, not free service restoration: with the fallback
+active, codex-authored work is reviewed by its own family again (the flip therefore includes
+`config/crosscheck-same-model` on for the duration, which the policy screen otherwise refuses),
+which is exactly the defect this requirement removes - accepted only while GLM is unavailable,
+and one more reason fallback activation must be loud.
+The model pick is explicitly provisional: reevaluate after live review data (Kimi-K2.7-Code was
+the prior same-day pick; the comparison and the custody/billing verification are in the owner's
+evidence folder, R6-FOUNDRY-RESEARCH-2026-08-19.md).

+## R10. Crosscheck is exposed to team engineers through Slack
+
+Status: NOT DONE. Directed by the owner 2026-08-19; builds after R6.
+
+The owner's v1 shape: an engineer tags the crosscheck bot in a Slack channel with a pull request
+link; the GLM lane reviews it; the bot posts the findings as a thread reply on the engineer's
+own message. No engineer wires up a harness or touches an endpoint, and the same path works for
+deliberate on-demand use. Cursor Bugbot continues to run for engineers' pull requests (it stays
+disabled on the owner's), so this lane complements rather than replaces it.
+
+Constraints the build must honor:
+
+- The listener uses Slack Socket Mode, so no public inbound endpoint is added to the private
+  lane posture. It is a resident process; where it runs is decided at build time and its
+  standing cost is recorded under C3.
+- v1 accepts pull request links only, and only for repositories in the organization allowlist.
+  The bot's repository read credential must never be pointed at a repository outside that
+  allowlist, because a review pulls untrusted content into a credentialed context.
+- Every thread reply names the lane that produced it (GLM, or the pi-codex fallback), the same
+  visibility R6 requires, so engineers and the owner can always see what is serving.
+- Team usage is metered per submitter under a daily cost bound (C3); when the bound is reached
+  the bot says so in the thread instead of silently dropping the request.
+
+Acceptance: an engineer other than the owner tags the bot with a pull request link and receives
+threaded findings produced by the GLM lane, with the lane named in the reply, the request
+metered, and an out-of-allowlist link refused with a clear message.
