# P270 Final Validation Record
This record is synchronized through P270. It supersedes the P269, P268, P267, P266, P255, and P246-only
final validation framings by adding the P248-P269 functional hardening and
validation-maintenance evidence: runtime-shape ROCm/HIP p-adic GEMM, repeated
benchmark summaries, planner-selected ROCm/HIP p-adic valuation lowering,
public prefer-gpu dense integer add selection, multi-overlap finite-site sheaf
locality provenance, optional Lean success transcripts, the JSC target
verification packet, selected-theorem strict profiles, bounded p-adic algebra
and finite-site sheaf evidence, post-P264 machine-checked roadmap guards, and
explicit fenced status blocks for claim and validation guards backed by reusable library validators.
Machine-checkable summary: this P270 record supersedes the P269, P268, P267, P266, P255, and P246-only final validation framings while preserving the P246 record below.
Machine-checkable evidence list: runtime-shape ROCm/HIP p-adic GEMM, repeated benchmark summaries, planner-selected ROCm/HIP p-adic valuation lowering, public prefer-gpu dense integer add selection, multi-overlap finite-site sheaf locality provenance, optional Lean success transcripts, JSC target verification packet blockers, selected-theorem strict profiles, bounded p-adic algebra and finite-site sheaf evidence, post-P264 machine-checked roadmap guards, explicit fenced status blocks, reusable library validators, expectation-driven status validation, and duplicate-key fail-closed status parsing.
These final validation records (P246, P255, P269, P270) are preserved in this single file as historical evidence and supersede one another. The current source of truth is the P440 record below; this P270 record is preserved unchanged as a historical milestone. P248-P254 functional hardening, P265-P270 validation maintenance, and the post-P264 machine-checked roadmap guards are summarized in this P270 record.
Historical P270 validation conclusion: the functional hardening and
validation-maintenance roadmap P248-P270 is complete only when default
validation, feature-gated ROCm/HIP validation, generated artifacts, schema
guards, structured roadmap guards, and paper/venue claim-boundary guards all
pass on the current worktree. Passing this record does not claim production
speedup, portable ROCm support, verified HIP machine code, arbitrary precision
p-adic fields, complete p-adic algebra, complete sheaf theory, full
proof-assistant formalization, verified SCI-Q2 status, submission readiness, or
acceptance probability.
# P440 Final Validation Record
This record is synchronized through P440. It supersedes the P439, P438, P437, P436, P435, P434, P433, P432, P431, P430, P429, P428, P427, P426, and all earlier final validation framings by extending the P248-P270 functional hardening and validation-maintenance evidence with the P276-P380 polish, P381-P410 polish, P411-P415 polish, P416-P420 documentation, and P426-P440 code-review improvement batches. The machine-checked fenced status block below is the current source of truth for validation guards; the P270 record above is preserved as a historical milestone.

Current P440 validation conclusion: the functional hardening, polish,
documentation, and code-review improvement roadmap P248-P440 is complete
only when default validation, feature-gated ROCm/HIP validation, generated
artifacts, schema guards, structured roadmap guards, and paper/venue
claim-boundary guards all pass on the current worktree. Passing this record

# P255 Final Validation Record
This historical record was synchronized through P255. It superseded the
P246-only final validation framing by adding the P248-P254 functional hardening
evidence: runtime-shape ROCm/HIP p-adic GEMM, repeated benchmark summaries,
planner-selected ROCm/HIP p-adic valuation lowering, public prefer-gpu dense
integer add selection, multi-overlap finite-site sheaf locality provenance,
optional Lean success transcripts, and the JSC target verification packet.

Historical P255 validation conclusion: the functional hardening roadmap
P248-P255 required default validation, feature-gated ROCm/HIP validation,
generated artifacts, schema guards, and paper/venue claim-boundary guards to
pass on the current worktree. It did not claim production speedup, portable
ROCm support, verified HIP machine code, arbitrary precision p-adic fields,
complete p-adic algebra, complete sheaf theory, full proof-assistant
formalization, verified SCI-Q2 status, submission readiness, or acceptance
probability.
# P246 Final Validation Record
This record is synchronized through P246. It does not add a new paper claim.
It converts the `todo.json` `next_success` condition into an auditable
validation checklist for the current certified valuation-sparse p-adic GEMM
route.
Current validation conclusion: the repository has no active implementation
backlog for the scoped C10 package when all gates below pass on the current
worktree. Venue-specific SCI-Q2 evidence, target formatting, author approvals,
DOI/container packaging, Criterion-grade benchmarking, broader external
baselines, portable ROCm support, verified HIP machine code, arbitrary
precision p-adic algebra, and full proof-assistant coverage remain outside the
repository-ready claim.
## P246 Completion Evidence Matrix
| Requirement from `todo.json` `next_success` | Authoritative evidence | Required command or guard | Claim boundary |
| --- | --- | --- | --- |
| Default gate remains green | `cargo fmt --check`, `cargo test --offline`, and `cargo run --quiet --offline --example paper_benchmarks` | Default validation must complete without failures. | Default gate proves repository artifact consistency, not production deployment. |
| `todo.json` is valid and aligned | `todo.json`, `tests/paper_artifacts.rs` | `python -m json.tool todo.json >/dev/null`; `todo_pivots_to_theory_engineering_runtime` | Active backlog may stay empty only while validation stays green. |
| Schema-guarded artifacts remain valid | `docs/schemas/tokitai-artifacts-v1.schema.json`, `docs/schemas/tokitai-paper-csv-v1.schema.json`, `tests/schema_guards.rs` | JSON schema parse commands and `cargo test --offline --test schema_guards` | Schema checks prove artifact shape, not semantic completeness beyond guarded fields. |
| Generated paper artifacts regenerate | `examples/paper_benchmarks.rs`, `target/paper-results/*.csv`, `target/paper-results/*.json`, `target/paper-results/theory-release-gate.json` | `cargo run --quiet --offline --example paper_benchmarks`; paper benchmark tests | Generated rows support controlled artifact evidence, not production speedup. |
| Release-gate theorem checks include bounded optional Lean behavior | `docs/paper/optional_lean_checker.md`, `docs/paper/schema_inventory.md`, `target/paper-results/theory-release-gate.json` | `cargo run --quiet --offline --example paper_benchmarks`; `tests/paper_benchmarks_example.rs` | Missing Lean remains skipped unless `TOKITAI_REQUIRE_LEAN=1` is set. |
| Signed audit trace gate passes | `ARTIFACT.md`, `docs/paper/release_checklist.md`, generated temporary audit trace files | Signed audit trace validation block from `docs/paper/final_submission_readiness.md` | Signed traces prove binding and fingerprints for the smoke path, not key-management completeness. |
| Feature-gated ROCm/HIP p-adic GEMM gate passes | `tests/rocm_padic_stratified_benchmarks.rs`, `examples/rocm_padic_stratified_benchmarks.rs`, `target/paper-results/padic-stratified-benchmarks/` | `cargo test --offline --features rocm-hip --test rocm_padic_stratified_benchmarks`; `cargo run --quiet --offline --features rocm-hip --example rocm_padic_stratified_benchmarks` | HIP evidence is local pilot evidence, not portable AMD GPU support. |
| ROCm/HIP benchmark artifact fields remain claim-safe | `target/paper-results/padic-stratified-benchmarks/padic-stratified-benchmarks.json`, `.csv`, `.md` | `rg -Fq '"artifact":"tokitai-padic-stratified-matmul-benchmark-report"'`; `rg -Fq '"certificate_coverage":true'`; `rg -Fq '"speed_claim_allowed":false'`; `rg -Fq 'rocm_hip_padic_stratified_matmul_pilot'` | Speed claims remain blocked unless future evidence explicitly justifies a scoped claim. |
| Reviewer-facing reproduction path is synchronized | `ARTIFACT.md`, `docs/paper/release_checklist.md`, `docs/paper/release_bundle_manifest.md`, `docs/paper/submission_checklist.md` | `tests/paper_artifacts.rs` release and submission guards | Reproduction docs are artifact-review guidance, not target-specific journal acceptance evidence. |
| Target-package controls keep the same gate | target formatting, manifest, freeze, evidence log, approval packet, and post-approval templates | `target_package_templates_preserve_feature_gated_padic_gemm_gate` | Target package work requires external venue and author decisions before a real submission. |
| Manuscript route remains C10-centered | `docs/paper/manuscript_draft.md`, `docs/paper/manuscript_skeleton.md`, `docs/paper/outline.md`, `docs/paper/contribution_map.md`, `docs/paper/table_figure_plan.md`, `docs/paper/related_work_synthesis.md` | `tests/paper_artifacts.rs` P233-P245 guards | C1-C9 remain supporting traceability, proof-evidence, nonstandard-domain, and reproducibility infrastructure. |
| Readiness and final decision stay synchronized | `docs/paper/readiness_audit.md`, `docs/paper/final_submission_readiness.md`, this record | `readiness_audit_tracks_current_padic_gemm_final_validation_status`; `final_readiness_entrypoint_matches_current_release_gates`; P246 record guard | Historical P155/P161/P230-style next-action text must not return as current guidance. |
| Venue controls preserve no-SCI-Q2-overclaim boundary | venue shortlist, decision brief, evidence request, evidence matrix, and integration docs | `venue_controls_track_current_padic_gemm_claim_fit_route` | Current SCI indexing and JCR quartile evidence remain unresolved until externally verified. |

## P246 Claim Discipline
When the validation gates pass, Tokitai can claim repository-ready evidence for
the scoped certified valuation-sparse fixed-precision p-adic GEMM
algorithm-system package: valuation-bucket fingerprints, theorem-bound skip
certificates, dense and certified sparse CPU oracle agreement, feature-gated
ROCm/HIP pilot rows, schema-guarded generated artifacts, signed audit trace
smoke evidence, synchronized manuscript materials, and fail-closed non-claim
guards.
Do not claim general GPU acceleration, production speedup, portable AMD GPU
support, verified HIP machine code, arbitrary precision p-adic fields, complete
p-adic algebra, full proof-assistant theorem coverage, current SCI-Q2 indexing,
or journal acceptance readiness without new phase-specific evidence.
