…lice 3 remains `rank-pow-dominated-by-head-Ω` (Slice 2-bplus) is in fact landed at `Ordinal.Buchholz.RankPowDomination` via PRs #133+#134 2026-05-27, not "remaining" as the doc claimed in three places. Updates: * Per-constructor verdict row for `<ᵇ-+1` — verdict text now reflects that the WfCNF-carrier domination side is COMPLETE and only the headline Slice 3 discharge remains; signature of the headline pinned inline. * Score paragraph — replaces "1 in flight with abstraction + per-marker dominances + inversion lemmas landed (Slice 2-bplus remaining)" with "1 in flight with the domination lemma landed (Slice 3 discharge remaining)"; adds PR #124/#130/#131/#133+#134 stage references. * "What remains open" entry for `<ᵇ-+1` — updates from "Slice 2-bplus remaining only" to "Slice 3 headline remaining only"; notes the `NonBzero` premise turned out unnecessary; pins the headline signature. * Status note — replaces "3 constructors blocked" (stale; `<ᵇ⁺-ψα` and `<ᵇ-ψΩ≤` are both closed) with accurate "11/13 closed + 1 side-cond + 1 head-Ω-route with only Slice 3 remaining". * See-also — adds `RankPowDomination.agda` entry pointing at the domination lemma + the `additive-principal-ω-rank-pow-succ` closure + the `rank-y-bound` atomic-tail helper. No proof / no code change; doc-only sweep aligning the obstruction verdict with on-disk state. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

PR #136 (session/doc-sweep-slice-2bplus-landed) introduced or touched 18 Echo*.agda modules without entries in echo-kernel-note.adoc, so scripts/kernel-guard.sh Check B (classification-drift lint) failed with exit 1 before Agda was even installed. Classifications (by in-repo import set): - EchoTotalCompletion: Tier 1 (only Echo + stdlib) — A ↔ Σ Echo encode/decode pair anchoring the F5 canonical-identity cohort - 17 others: Tier 2 (multi-hop) — split between the F5 canonical- identity / OFS cohort and the application/extension modules. F5 cohort: EchoOrthogonalFactorizationSystem, EchoImageFactorization, EchoNoSectionGeneric, EchoLossTaxonomy, EchoResidueTaxonomy, EchoDecorationStructure, EchoObservationalEquivalence, EchoOFSUnivF5, EchoOFSUnivF5Diag, EchoOFSUnivF5Iso, EchoCanonicalIdentitySuite. Application/extension: EchoEntropy, EchoLLEncoding, EchoProvenance, EchoSecurity, EchoProbabilisticSupport, EchoDifferential. Kernel-guard check A (funext-free certificate) continues to pass. Both checks PASS locally after this change. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

The "Expected-failure gate (N5Falsifier is known-broken)" step was asserting that proofs/agda/characteristic/N5Falsifier.agda fails the typechecker (per the 2026-05-18 foundation audit). That hold no longer holds: the module was resolved 2026-05-27 by pinning the implicit r / grade at the four applyRole / applyGrade call sites, and is already imported by characteristic/All.agda (line 33). The xfail step's own self-disclosed instructions fired in the previous CI run, telling us to "register it in characteristic/All.agda and remove this xfail gate". In-source bookkeeping is already complete on this branch: - N5Falsifier.agda banner rewritten as "HISTORICAL BROKEN BANNER (resolved 2026-05-27)" with the resolution narrative. - characteristic/All.agda has the import (line 33). - The previous CI run confirmed N5Falsifier typechecks (the xfail gate failed precisely because it succeeded) and that characteristic/All.agda typechecks WITH the import. Net diff: -17 lines from .github/workflows/agda.yml. No Agda code changed by this commit. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
Doc-only sweep.
docs/echo-types/buchholz-rank-obstruction.adocclaimed in three places that "Slice 2-bplus" (the WfCNF-carrier dominationrank-pow-dominated-by-head-Ω) was still remaining, but it landed via PRs #133+#134 2026-05-27 atOrdinal.Buchholz.RankPowDomination. Only Slice 3 (the headlinerank-mono-<ᵇ-+1-via-head-Ωdischarge) remains in the per-constructor matrix.Updates:
<ᵇ-+1— verdict text now reflects WfCNF-carrier domination side is COMPLETE; pins the headline signature.<ᵇ-+1— updates to "Slice 3 headline remaining only"; notes theNonBzeropremise turned out unnecessary (rank-pow bzero = ozis strictly belowω-rank-pow-succ (fin 0) = ω^2); pins the headline signature.<ᵇ⁺-ψαand<ᵇ-ψΩ≤closed) with accurate "11/13 closed + 1 side-cond + 1 head-Ω-route with only Slice 3 remaining".RankPowDomination.agdaentry pointing at the domination lemma + theadditive-principal-ω-rank-pow-succclosure + therank-y-boundatomic-tail helper.No proof / no code change; doc-only sweep aligning the obstruction verdict with on-disk state.
