Conversation
claude-code 2.1.246 -> 2.1.252, codex 0.150.0 -> 0.151.0, opencode 1.18.23 -> 1.18.25, pi 0.84.3 -> 0.84.4, agent-browser 0.35.1 -> 0.35.2, cua-driver 0.19.3 -> 0.23.2. Ghostty stays at 1.3.1-0.ppa2, the newest trixie deb upstream publishes. ble.sh (nightly), mise toolchains, Chrome, and sandbox-api already resolve to latest at bake. Epoch r12.

📝 WalkthroughWalkthroughThe Blaxel Docker image updates its rebuild epoch and pinned CUA driver and coding-agent versions. ChangesBlaxel image updates
Estimated code review effort: 2 (Simple) | ~5 minutes Merge Risk: 🟡 Moderate · up to The image now builds newer agent versions, but the Blaxel manifest still describes the previous pins and validation metadata. Publishing without regenerating it could expose mismatched image metadata, so the manifest update should be completed or explicitly accepted before merge.

Regenerate the Blaxel image manifest for this epoch.
The Blaxel build script requires a manifest update after each bake. manifest.json still records the prior agent pins and r7 validation metadata, while the Dockerfile builds epoch 2026-08-31-r12 with newer pins. Add the new validated entry before publication.

Pins to current latest, verified against npm and GitHub releases today: claude-code 2.1.252, codex 0.151.0, opencode-ai 1.18.25, pi 0.84.4, agent-browser 0.35.2, cua-driver-rs 0.23.2 (was 0.19.3; install contract unchanged upstream). Ghostty 1.3.1-0.ppa2 is still the newest trixie deb. ble.sh nightly, mise toolchains, Chrome, and sandbox-api resolve to latest at bake. Epoch 2026-08-31-r12, already baked to sandbox/cmux-devbox:latest and live-verified in a sandbox (all versions confirmed). Devbox Dockerfile parity bump is a flagged follow-up. vm-blaxel-image tests green.
