Worker attestation

Before flipping this PR to ready for review, confirm each item:

• Title describes the change (not the session id or branch).
• PR body summarises what and why (replace the TODO below).
• Tests run: name the command (e.g. npm test, cargo test) and the result.
• If this closes a work item, the body contains a Closes #N directive.
• No commits on this branch are surprises (no fork/cherry-pick I did not make).
• No secrets / credentials / large binaries staged.

Summary

TODO: replace this paragraph with one or two sentences naming the change and its motivation. Reviewers read this first.

Test plan

• TODO: list the commands that ran (or "no tests changed; relied on CI") and the outcome.

Closing as abandoned duplicate: Worksheet A compute_fabric implementation is tracked on #4105 (session/sharp-wolf-compute-fabric-impl, ready-for-review with dashboard approvals). This draft was auto-opened for child still-koi-542; no unique scope.

Verified against current GitHub state:

• feat(dsl): land dsl/std/compute_fabric.dag (Worksheet A §6) #4105 (session/sharp-wolf-compute-fabric-impl) is the canonical Worksheet A landing: dsl/std/compute_fabric.dag, ready-for-review, with dashboard approvals (claude + cursor on HEAD d45b07e).
• Land dsl/std/compute_fabric.dag (Worksheet A §6) #4106 (session/still-koi-542) duplicates that substrate on a parallel child branch. No unique merge scope remains; CI here is red on a superseded line of work.
• Only delta on this branch: P-CF-TYPE smoke tests (compute_fabric_dag_smoke_test.rs + integration.rs hook). If those are still wanted on the canonical PR, I can open a follow-up against feat(dsl): land dsl/std/compute_fabric.dag (Worksheet A §6) #4105’s branch—otherwise nothing to salvage on Land dsl/std/compute_fabric.dag (Worksheet A §6) #4106.

Closing #4106 as abandoned duplicate per parent coordination. Merge target: #4105.
