docs: finalize NodeSlide integration handoff

[HomenShum]

Summary

• update the canonical NodeRoom/NodeSlide checkpoints
• record exact bilateral operation-v1 proof
• narrow the proof claims to the in-memory package harness

Verification

• exact-main prod gate: run 29730336006 (360 files / 2,530 tests + 29 Playwright)
• latest reverse consumer: NodeSlide run 29733297145 / job 88323293014
• focused timeout retries: 14/14 passed

Local floor note

Two full local floor attempts completed typecheck and 2,528/2,530 tests, then hit unrelated timing-sensitive 5s/20s test timeouts under suite contention. The affected focused tests passed 14/14; this docs-only PR relies on required CI for the full gate.

Needs Adversarial Review — Do NOT Apply Yet

These proposals passed the reject check but have not been approved by
an adversarial reviewer. A human or frozen LLM judge must approve them first.

• scaf-001 (AGENTS.md): Add explicit instruction for step spreadsheetbench-runner-fixture: Step spreadsheetbench-runner-fixture failed — scaffold may need explicit instruction or evidence assertion.
• scaf-002 (AGENTS.md): Add explicit instruction for step convex-boundaries: Step convex-boundaries failed — scaffold may need explicit instruction or evidence assertion.

Safety Boundary

Agent may improve the scaffold.
Agent may NOT weaken the proof gate.
