+# IBA2-010 interface ledger: regional imports behind [CP] and [SC]
+
+Scientific effect: **NONE**. Dylan Roy, delegated AI work. Author: Anthropic /
+Claude, Claude Code session `session_015wNj8LPTKXsaT68G3DgPPh` (claim main#259
+comment 6001134368).
+
+**This is an author-side map, not an audit.** It makes no acceptance, closes no
+IBA2 item, and changes no status. The ledger author also wrote [CP]
+(`c6_palm_route`) and [DL]/[D5] (`d5_dimension_lift`). The IBA2-010 audit itself
+needs a **non-Claude** owner. Everything below was checked mechanically against
+Math- `main` at `dcd2a886e322738324a745adcad12fd3735bd2c5`:
+- pins: `git rev-parse main:<path>` compared with each consumer's recorded blob;
+- review IDs: read from the GitHub API.
+
+Equation and section references are reproduced **as the consumer cites them**.
+Checking that each cited statement matches its use, hypothesis by hypothesis, is
+the auditor's job (§3).
+
+## IBA2-010 as stated (main#259 audit II)
+
+> Sharp factorial moments and the support-{1,2} cluster law. Conditional
+> deductions survive; complete upstream verification remains open in this audit.
+> Reconstruct named regional covariance/collision interfaces before declaring
+> full closure.
+
+The audit's bound sources, at Math- `b55b8f34`:
+- [CP] `frontiers/c6_palm_route_20260929/PROOF.md`, blob `89eb8adf`;
+- [SC] `frontiers/spectral_cluster_closure_20260929/PROOF.md`, blob `16c56821`;
+- [CL] `frontiers/c6_factorial_moment_20260929/PROOF.md`, blob `f5bd013b`.
+
+All three blobs are unchanged on current `main`.
+
+## 1. [SC] (OpenAI / GPT-6 Astra Pro), named imports (SC §1, `SOURCES.json`)

+## 2. [CP] (Anthropic Claude, this author), regional rows of §6 and inputs (`SOURCE_MAP.json`)
+
+All 8 `SOURCE_MAP.json` inputs are unchanged on `main`: [C6L] `f5bd013b`,
+[DL] `9d82c707`, [LP] `dfed3b8d`, [PP] `d8acf0bc`, [CP-collar] `b5647907`,
+[IW] `f53a527c`, [RM] `b383bfcc`, [EDL] `7303bd79`.
+
+| [CP] §6 row | Frame / interface consumed | Source statement | Nonauthor review on file |
+|---|---|---|---|
+| R1, pin balls | `Y` of [DL] §4, (4.2)–(4.12) | [DL] Theorem P_d; planar (P10)–(P12), (P18)–(P20) | Math-#141 5357858391; planar xAI 5894512272 and Math-#111 |
+| R2a–R2c, collar | raw `∇f` [DL] §5.4; `Gc` [DL] (5.2)–(5.3); fixed floor [DL] §5.6 | [DL] Theorem C_d; planar (C4)–(C19); floors `c r¹⁰`, `c|v|⁴`, `c` | Math-#141 5357858391; `reviews/d5_collar_count_20260928/` |
+| R3a–R3b, shells | raw `(∇f, f)` [DL] §6.5; `Z` [DL] (6.4), (6.11) | [DL] Theorem I_d; planar (I9)–(I33); floors `c s¹⁰`, `c|v|⁶` | Math-#141 5357882570; `reviews/d5_i5_planar_f_20260928/`; Math-#107 Claude analytic review via Math-#109 |
+| R4, remote | `Y_x = (∇f(x), f(x))`, [RM] §§2–3, (10), (14) | [RM] Theorem A, uniform remote nondegeneracy, coupling (5) | main#76 |
+| normalizer | `Z_r ≥ z_* r²` | [LP] (5.5) | Math-#106 |
+| Lemma D / R / §8 | [C6L] §§2–5, Lemma R, §8 assembly | [C6L] | Math-#140 OpenAI 5355120953, 5355457002, 5355682335; xAI 5894209739 (Lemma R and §8) |
+| Corollary Θ (lower bound only) | `Q^W(N_r ≥ 2) ≥ c r³` | [EDL] (A4) | Integrated by Math-#129. Not needed for the IBA2-010 **upper** bounds. Review status not re-traced here. |
+
+## 3. What the IBA2-010 auditor still has to check
+
+Only an independent check can supply these. The ledger supplies the map, not
+the verification.
+
+1. **(2) for [SC].** [RC] Corollary D's all-index scope and fixed-ρ uniformity
+   must cover [SC]'s use with Λ as the **sum** of the index-specific kernels.
+   [RM]'s `O_ρ(r⁴)` remainder must hold at the same marks and window.
+2. **(1) for [SC].** The shell estimate's uniformity in `R ≥ 4` and ρ must match
+   [SC] §7's choice `R_r = ρ'/r` with ρ' fixed. [SC] states this is permitted;
+   the auditor confirms it against [D5].
+3. **[CP] §6 joint-floor rows.** Each floor exponent and each Gaussian tail
+   factor in the R1–R4 table must be the one the cited [DL] equation proves, for
+   the conditioned measure `Q_r` with the extra witness conditioning. [CP] §6
+   reads them from [DL] and [RM] §3.
+4. **Gap at `d ≥ 3`.** For `d ≥ 3`, both [CP] and [SC] consume [DL]'s continuum
+   rows. Their acceptance is OpenAI's source-exposed review (Math-#141); the
+   planar rows have xAI and Claude records. Whether that suffices for "full
+   closure" is the auditor's call.
+5. **[EDL].** Out of scope for the upper bounds. If the audit also covers the
+   matching lower bound (Corollary Θ), trace [EDL]'s review separately.
