- [x] F4b Extension pipelines (oxygen-vscode, oxygenhub-vscode): typecheck, bundle, tests and package, offline. Needs the npm packages in the build image, and `oxy` for oxygen-vscode's tests (built in the job from a pinned oxygen). The hub client tests skip without a hub binary.
64 64 
- [x] F6a Runner runs several jobs at once within a budget (Earth: 3 jobs, 24 GiB, 8 vCPUs); the hub hands out only jobs that fit the room the runner reports.
65 65 
- [x] F6b1 Faster Rust jobs, first part: CI builds without debug info or incremental state, set once in each pipeline's rust sandbox env.
66 - 
- [ ] F6b2 A warm dependency cache: the dependencies of each lock file prebuilt in the build image and copied onto the job's scratch disk; measured on oxygenhub.

- [x] F6b2 A warm dependency cache: the dependencies of each lock file prebuilt in the build image and copied onto the job's scratch disk; measured on oxygenhub.
67 + 
- [ ] F6b3 The same prebuilt dependencies for oxygen and oxygenflow (one image rebuild, all pipelines re-pinned).
67 68 
- [x] F5 Required checks: each repository's default bookmark requires its pipeline's checks to land, and the work loop pushes and waits for green instead of gating only locally.
68 69 
- [x] O10e Checkpoint payload version 2: large file graphs as shared blobs named from an index, read and decoded in parallel; readers accept both versions (spec §11). Agreed by Andy on 2026-09-28.
69 70 
- [x] M1 (metalgear feedback 1, reported by Andy) Bookmarks with `/` in their names could not be pushed: attestation and checkpoint files are now flat, escaped names (oxygen#12). The hub is pinned to the fix and deployed.

  - **At 10 000 files:** diff 0.57 → 0.22 s and commit 0.58 → 0.23 s, each 244 → 52 MB; show 0.53 s.
583 584 
  - Caching materialized states turned out unnecessary.
584 585 
  - One test: works with an unreadable unchanged file, and shows a change exactly as a full base renders it. Run green.

- 2026-09-29 **F6b2 done** (oxygenhub#29 refs; oxygenflow image recipe).
587 + 
  - **Recipe.** `images/rust/recipe.py` writes a workspace's dependency recipe: manifests, the workspace roots path dependencies inherit from, the lock file, real build scripts, and stub targets. Checked to resolve offline with the lock unchanged.
588 + 
  - **Image.** It builds oxygenhub's recipe at `/src` with the pipeline's environment (release, tests, clippy) and keeps `/opt/warm/oxygenhub` (2.1 GB, image 5.2 GB).
589 + 
    - It was exported straight to Earth over ssh, since the local scratch quota refused the tarball.
590 + 
    - Imported as `cas://blob/47b614a6…`.
591 + 
  - **Jobs.** `.flow/warm-target.sh` copies the warm target onto the job's empty disk (8–12 s), then runs cargo. A missing cache or a failed copy falls back to a full build.
592 + 
  - **First run found a bug:** the fresh ext4 disk holds `lost+found`, so the "empty" check skipped the copy. Fixed.
593 + 
  - **Measured on Earth:**

  - I ran `git --version` once by mistake while checking a pipeline. It touched no repository.
