paper: preserve GRACE boundary and preregister next evidence

[ShuhaoZhangTony]

Scope

Advisor-authored preservation and next-evidence draft only. The accepted manuscript is absent and is not reconstructed. Hongru Gao retains implementation, environment, experiment, and result ownership.

Exact identity

• PR head: c8b06e08bf8beb04a3080814a9eae82e34cde153
• artifact commit: 81a939ece431b9353858f06651d3cd41fb4e0eb7
• base: 9f81318ecb12cbb5531034a574f6136f65d6b8e2
• PDF: 2 pages

Boundary

The draft preregisters a structural-drift reconstruction decision across PPCSR, Terrace, and VCSR. It requires exact upstream pins, matched fixed-period/fixed-density/oracle arms, snapshot correctness receipts, winner-switch plus oracle-headroom, and explicit stop rules. Existing logs remain historical/unbound; no new result is claimed.

Verification

• Tectonic exit 0, no warnings; both pages visually checked.
• git diff --check: pass.
• PPCSR build attempt: not run because cmake is absent; no dependency installed and no green build claimed.

Keep Draft; do not merge without explicit user confirmation.

@ShuhaoZhangTony 112 independent review requested for exact head c8b06e08bf8beb04a3080814a9eae82e34cde153. Advisor narrative only; no accepted-paper claim reconstruction, mechanism work, or experiment. Tectonic exit 0 (2 pages), 2/2 pages visually checked, diff check passed; host build remains unrun because cmake is absent.

51-paper final audit — PASS at exact head c8b06e08bf8beb04a3080814a9eae82e34cde153

Canonical repository/base, exact-head paper assets, independent Tectonic rebuild, bibliography/citations, and page rendering pass. The manuscript closes the project-specific seven-question contract with strongest baselines, matched arms, correctness oracle, metrics/gates, evidence boundary, and stop conditions; claims do not exceed the retained real-online/replay/simulation/probe/derived evidence, and NPU architecture claims are bounded to the documented causal chain where applicable. This PR remains Draft; this review does not merge it or authorize experiments.
