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.

Non-blocking — Strengths

• docs/r3-program-plan.md Design/docs-only status promotion aligns with R3 gate #21 acceptance; the cited Rust test covers canonical fixed-width Int/UInt refinements and selected alias chains, though local cargo verification was blocked by offline crates.io dependency resolution.

✅ No blocking concerns.

Review triage (quiet-boar-853)

1. claude / claude-opus-4-7 (dashboard stdout, sha 9bf01f0c) — Confirmed against HEAD: docs/r3-program-plan.md §1.8 row #21 is CONSUMER_LANDED + PASSING with citation to src/v3/compiler/tests/integration/int_literal_cardinality_test.rs; int_refinement_overflow_is_proven_parametric_for_representable_widths is present (currently starts ~line 528 after the merge-from-main). No fix commit: finding matches the tree.

2. codex (GitHub api-review thread, sha 3a8b1d06) — Same substance: doc-only gate promotion; cited receipt test unchanged in role. No blocking concerns align with the current diff (no new hand-Rust / substrate / P5 surface in this PR).

Merge readiness (dashboard source of truth) — dashboard-ops reviews gunb-ai/gunbc#3098 still reports 1/2 distinct dashboard approval providers (claude only; both posted artifacts are claude-opus). The Codex “No blocking concerns” review lives on the GitHub thread with api-review metadata but is not listed in that summary’s approval_providers, so I am not squash-merging yet under the ≥2-distinct-provider rule. Latest GitHub checks for this HEAD are green (ci / fmt / v3 / self_host_ratchet on run 25874521354). Next step: second distinct provider in the dashboard review feed (e.g. scheduled openai-pro) on the current HEAD, or operator wiring if GitHub-posted codex approvals are intended to satisfy the ledger.

Triage: cursor / composer-2 (review 11964, sha d389d590)

• Verified: origin/session/quiet-boar-853 vs origin/main is one file — docs/r3-program-plan.md (+1/−1). Row Implement testgen infrastructure with node I/O examples #21 at ~line 248 is CONSUMER_LANDED + PASSING with the cited receipt path + int_refinement_overflow_is_proven_parametric_for_representable_widths. That test and assert_magnitude_out_of_range are unchanged pre-existing integration surface (not expanded by this PR). Ledger text matches the test’s single-diagnostic MagnitudeOutOfRange shape. No fix commit — the review is materially correct.

• Merge: dashboard-ops now shows 2/2 distinct providers (claude, cursor) and no REQUEST_CHANGES. GitHub still reports branch policy not mergeable from here while checks are in flight / recomputing (and this environment hit REST rate limits polling Actions). Please re-run gh pr checks 3098 once v3 is green, then gh pr merge 3098 --repo gunb-ai/gunbc --squash --delete-branch (auto-merge is disabled on the repo).

Triage: cursor / composer-2 (review 11996, sha 1fd3f1d9)

• Verified: PR diff remains doc-only (docs/r3-program-plan.md §1.8 row Implement testgen infrastructure with node I/O examples #21). Receipt int_refinement_overflow_is_proven_parametric_for_representable_widths + assert_magnitude_out_of_range on origin/main match the ledger wording (single semantic MagnitudeOutOfRange with target + inclusive bounds). No fix commit — findings list is empty for good reason.

• Outcome: Branch protection cleared after v3 / ci / fmt / self_host_ratchet green on run 25877549549; squash-merged at 2026-05-14T18:30:56Z. Dashboard at merge time showed 2/2 distinct providers (claude, cursor) and no REQUEST_CHANGES.
