 The graph has sixteen lanes: SCM compatibility · namespace · P-derive · observation · placement · compute · CI cost · CI control · generated artefacts · v1 exit (four finish lines: compiler fixed point, interpreter deleted, products v1-free, zero hand-maintained Rust) · shell · roadmap runtime · fleet/hygiene · judgment · hermetic toolchain · compiler-guarantee (the DESIGN §4b ladder climbs; rung STATE lives in the guarantee claims carrier and is emitted, never restated in tickets — [gap analysis](docs/plans/compiler-guarantee-recovery-gap-analysis.md)). The three independent SCM R0 models, the separate P−1 evidence carrier, R1 compatibility-shape extraction, and P0 user-contract/landing spine are accepted; the operator-authored P1 proof-kernel node is active and fail-closed pending its first discriminating closing validation, while P2 and later product lanes remain parked. The toolchain pin model is an independent root. The P-derive receipt feeds the emitter fixed point, so the v1 chain nests under it. Compute owns the one contract everything else asks for work through — an exact subject in, a typed ending and the outputs it promised back out — and it sits ABOVE CI rather than inside it, because owning CI, converging the fleet, serving models and eventually judging changes are four consumers of one fabric, not four execution systems. It grounds on the signed realization spine rather than minting a second scheduler beside it. CI control owns who starts, queues and hands out required work and how its result reaches GitHub; CI cost owns how much computation that work performs. Fleet owns whether a merge to main becomes applied machine state and whether that question has one answer. Node fields define boundary, first slice, RED control, exclusions, owner, and handback.

 - [x] **Run the worker on DeepSeek V4 Flash with thinking on, straight at the engines, from briefs it can finish** — The harness posts to the Spark vLLM engines directly on the chat-completions shape with Think Max as the request switch, decodes inline reasoning client-side, replays it, and derives its deadline from the engine's own decode rate. A write brief names files small enough to hold whole and the decisions already made. Why: A day of runs with 0 files changed: briefs naming one file when the change spans its importers, a co-tenanted router killing every long step, a deadline that could not cover max_tokens, and agents deliberating modeling decisions a brief should have made.

 - [x] **The roadmap commits, verifies, and opens the pull request itself once verification passes** — After the provider completes, the belt commits the attempt worktree, verifies the committed head in a detached checkout, admits publication only on a ValidationPassed receipt for that exact head, and the token-holding helper pushes the branch and opens the pull request, then answers with what GitHub shows. Why: Verification was checking out an uncommitted worktree's head, publication never consulted the verdict, and no operation existed to push or create a pull request, so every attempt stalled in the Agent segment and a human harvested by hand.
