docs(r3): mark gate #75 pr_anticipation_discipline_ci_active CONSUMER_LANDED

[briansrls]

Summary

R3 §1.8 gate #75 pr_anticipation_discipline_ci_active is satisfied at HEAD: .github/workflows/ci.yml ci job already runs scripts/check-pr-sg0-net-shrink-discipline.sh --self-test on every non-draft run and runs the script with PR_BODY on pull_request when sg0_census_test.rs differs from origin/main.

This PR only updates canonical program docs so the ledger matches CI reality:

• docs/r3-program-plan.md — §1.8 row Lane A tasks #75, §3 T-Debt-Paydown blocker cell, §1 PR-anticipation bullet, §10.3 Q-PR-Anticipation-Gate status
• docs/r3-structure.md — §Acceptance PR-authoring-discipline bullet

Dashboard work item: dashboard://work-items/r3-gate-75-26e2c4d7 (R3 gate #75).

Test plan

• bash scripts/check-pr-sg0-net-shrink-discipline.sh --self-test (local)

Director ratified #2588 as the canonical gate #75 bind after this duplicate worker PR appeared. Please treat #2592 as redundant pickup from the auto-spawn race; canonical artifact is #2588.

Closed as duplicate per Director ratification: gate #75 canonical bind is #2588 -> silent-ram-834. This auto-spawn PR raced with the manager-authored artifact.

[briansrls]

Verification (crisp-ferret-875)

Checked GitHub state: #2588 is still OPEN (session/silent-ram-834, “mark Debt-Paydown gate 75 passing”) and is the broader ledger bind Director ratified. #2592 is already CLOSED as duplicate (same gate #75 doc intent from auto-spawn race).

No further code or doc commits from this worker: any additional edits would re-open churn against the canonical #2588 line.

Merge readiness for #2592: not applicable — PR is closed; downstream should track #2588 only.

crisp-ferret-875 — item 1 (duplicate close comment)

Re-verified against GitHub: #2592 is CLOSED at 2026-05-10T14:47:51Z with rationale matching your note — canonical gate #75 bind remains #2588 (session/silent-ram-834), still OPEN. No code/doc delta is warranted on this closed PR; any gate #75 ledger work belongs on #2588 only.

Merge readiness (#2592): N/A (closed). #2588 at snapshot: ci/v3 still pending, mergeStateStatus BLOCKED, reviewDecision empty — not merge-ready from this shell’s view; silent-ram-834 should drive #2588 through reviews + green CI.

Manager closure note for dashboard://work-items/r3-gate-75-26e2c4d7: canonical #2588 has merged (dbccd6d53, 2026-05-10T15:08:58Z) and carries gate #75 to main under Director-ratified bind gate #75 -> #2566 -> PR #2588 -> silent-ram-834.

This duplicate PR #2592 should remain closed and should not hold the work item open. Dashboard rebind/close commands are not available in this manager container, so this is the GitHub fallback receipt for operators/dashboard.
