P0 — L1 blockers

B-L1-01 — Trusted original resolver-selected provenance

Status: ❌ REQUIRED

Need one protected/original-process receipt binding process/build, successful mount topology, selected provider/volume/member, archive identity, materialized bytes and trusted observer state.

B-L1-02 — Exact selected representation classification

Status: ❌ DEPENDS ON B-L1-01

Do not infer writer authority from filename, transformed texture data or an unrelated retail corpus.

B-L1-03 — Same-lineage authored rebuild/rematerialization

Status: ⚠️ REAL RETAIL PNST/PAC GATES EXIST / ORIGINAL-SELECTED LINEAGE OPEN

MOD already has provenance-bound real retail PNST reintegration. SCM has hash-bound real same-layout alpha/translation/rotation PAC receipts plus a real size-changing canonical SCM rebuild reinserted into real st001.pac, with canonical reopen/extraction, exact authored-child rematerialization and byte-exact preservation of every non-target top-level physical slot. These are strong bounded container receipts but are not yet the original resolver-selected protected lineage.

Still required:

original-selected member
 -> exact representation classification
 -> evidenced bounded edit
 -> parent rebuild
 -> authored higher-numbered NBZ
 -> original resolver selects authored overlay
 -> exact authored member rematerializes
 -> original consumer reaches authored child

B-L1-04 — Original consumer effect + rollback

Status: ❌ REQUIRED

Need SHA-bound authored overlay selection, deterministic original-game effect attributable to authored bytes, then rollback with original retail artifacts unchanged.

B-L1-05 — Final L1 audit

Status: ❌ OPEN

L2 blockers

B-L2-01 — Wider collision scope

Status: ✅ EXACT dmc3-0.nbz CLOSED / ❌ WIDER SCOPE OPEN

Exact bound archive: 4,333 file keys / 4,333 unique / 0 collisions. Additional volumes and cross-volume normalized-key behavior remain open.

B-L2-02 — Discovery vs successful mount topology

Status: ✅ CLOSED BY PR #287

B-L2-03 — Protected-process RVA mapping

Status: ❌ REAL R2B RECEIPT REQUIRED

Canonical analysis VAs/RVAs cannot be applied to a different protected distribution build without independent mapping evidence.

B-L2-04 — Trusted selected-provider identity

Status: ❌ REAL R3 RECEIPT REQUIRED

B-L2-05 — Direct-retail original resolver winner

Status: ❌ ORIGINAL OBSERVATION REQUIRED

B-L2-06 — Final L2 audit

Status: ❌ OPEN

Native Reader registry boundary

Direct inspection of NativeReaderModuleRegistry on current main confirms canonical module registration for DDS, PTX, HITS, DCA, LIG2/LIG, Stage TXT, SCM, MOD, MOT, SO graph, SO volume, SO link, SHW and PE/EXE.

Therefore older blocker text saying “MOT canonical Native Reader module is open” is obsolete.

Registry membership is not full semantic/writer authority.

  • ❌ EFM Native Reader module remains open.
  • ❌ MRP/MCV/CAM/CLT/TSC and other recognized families remain evidence-gated.

MOD boundary

Reverse: ✅ COMPLETE for canonical serialized/runtime scope.
Writer/integration: ✅ bounded writer + real retail PNST reintegration / ❌ full writer + retail NBZ + original-game acceptance open.

Closed at exact scopes:

  • #365 Preserve-Layout Writer Gate 1;
  • #368 38/38 provenance-bound retail no-op exact byte parity;
  • #369 one provenance-bound controlled retail radius edit + receipt trust bridge + synthetic PAC reintegration;
  • #372 provenance-bound real retail PNST reintegration/reopen;
  • #372 synthetic MOD -> container -> NBZ overlay -> reopen.

Still open:

  • typed-IR-only layout synthesis/reflow;
  • transform authoring;
  • skin/blend-index authoring;
  • source-flag/material/texture-binding authoring;
  • texture-companion rewrite/coherence;
  • broader preserved-undecoded mutation authority;
  • provenance-bound retail NBZ overlay acceptance;
  • original dmc3.exe no-op/edited MOD acceptance;
  • complete current animation/pose ownership;
  • any 100% MOD writer claim.

These are not MOD reverse blockers.

SCM boundary

Reverse — COMPLETE

Status: ✅ COMPLETE for canonical DMC3 HD serialized/runtime SCM scope.

Completion authority:

  • docs/research/dmc3-scm-reverse-completion-2026-09-13.md;
  • data/reverse/dmc3-scm-reverse-completion-20260913.json;
  • reconciled docs/formats/scm.md.

There are zero current RESEARCH_REQUIRED field-consumer gates in the terminal map. Every serialized/runtime domain is typed/structural, preservation-only (PRESERVED_UNDECODED / RESERVED_OBSERVED_ZERO) or explicitly rejected/superseded. Lack of an invented artistic/source-code name is not a reverse blocker.

Closed domains include header/resource-code state, object alpha/flags/bounds, GS TEX1 and GS TEST/ZBUF technical selectors, terminal source bit 0x00200000 preservation, fixed 0x50 mesh ABI, GS CLAMP, all vertex streams, topology/index generation, scene hierarchy/binding, SCM-specific local/world transform path and external texture-companion ownership.

Writer/integration — bounded, separate

Status: ✅ canonical bounded writer/rebuild + real same-layout and size-changing PAC receipts / ❌ production + NBZ + original-game acceptance open.

Closed at current scopes:

  • preserve_layout;
  • deterministic canonical_rebuild;
  • typed geometry/normal/UV/texture-slot/alpha/filter/GS-CLAMP/node-transform editing;
  • mandatory reparse and mutation guards;
  • fail-closed reflow on non-zero unmodeled source bytes;
  • bounded texture-companion coherence;
  • 78 paths / 68 unique inputs with 78/78 parse, preserve-layout exact parity, canonical rebuild+reparse and canonical exact no-edit parity;
  • real hash-bound alpha, node-translation and node-rotation edits with parent PAC reintegration, reopen/extraction and exact inverse restoration;
  • PR #386 real hash-bound st001.scm size-changing canonical rebuild: object 0 / mesh 0 grows 167 -> 168 vertices, SCM grows 887,760 -> 887,776 bytes while non-degenerate triangles remain 118;
  • PR #386 real st001.pac packed reflow: parent grows by the same 16 bytes, reopened slot 2 equals the authored SCM byte-for-byte, and all seven non-target top-level physical slots remain byte-identical.

Machine authority for the size-changing gate: data/reverse/dmc3-scm-real-size-changing-pac-reintegration-attestation-20260913.json.

Still open:

  • provenance-bound real geometry/normal/UV/filter/GS-CLAMP edit receipts where useful for writer promotion;
  • provenance-bound retail texture rewrite;
  • broader PNST authored-resource delivery for SCM;
  • retail NBZ authored-resource delivery and resolver selection;
  • original-game acceptance;
  • universal/100% production writer claim.

These are writer/integration/acceptance gates and must not be reported as unfinished SCM reverse.

MOT boundary

Status: ✅ CANONICAL NATIVE READER MODULE + PARSER/IR + BOUNDED NORMAL-PATH CHANNEL EVALUATION / ❌ COMPLETE PLAYER PARITY OPEN

MOT already exists in the canonical Native Reader registry as native_reader_modules::mot(). PR #372 replaces duplicate structural decoding with the modular parser/IR and promotes bounded canonical-EXE-backed key evaluation. The current reverse/mod-completion-20260907 branch additionally closes the static compression-3 cached-search path and composes it with exact normal-path T/R/S channel binding plus the MOD motion-group selector.

Closed at current scope:

  • MOT\0 marker and aligned header/channel-mask contract;
  • nine-bit channel mask and record/popcount relation;
  • compression-2/3 typed key payloads;
  • three hash-bound real MOT payloads through the modular parser;
  • exact normal-path binding-bit traversal and track ordinal consumption;
  • exact Translation/Rotation/Scale channel semantics and CMotionJoint channel bases;
  • signed track start-time offsets;
  • quantization decode;
  • compression-3 forward/backward cached segment search at 0x1402E8C80..0x1402E8E10;
  • endpoint behavior and cache-dependent duplicate-time selection in the recovered static algorithm;
  • compression-3 linear/Hermite segment algebra and slope orientation;
  • group-aware compression-3 scalar projection through the EXE-confirmed MOD motion-group selector.

Still open:

  • execution/differential confirmation of cache lifecycle and bit-identical SSE parity where required;
  • header flag 0x2 alternate binding at 0x140310CBF;
  • compression-2 whole-track evaluation parity and other compression modes;
  • exact mutable CMotion channel-state ownership;
  • T/R/S channel state -> animated local matrix construction around the normal 0x14030E9B0 path;
  • looping/blending/motion-selection/scheduler lifecycle;
  • original-game output comparison.

The next direct-EXE acquisition surface is tracked by data/reverse/dmc3-mot-local-matrix-window-plan.v1.json. Do not promote joint+0x110 to a final animated-local matrix until that packet closes ownership and write ordering.

SO boundary

Status: ✅ SO GRAPH/VOLUME/LINK REGISTRY MEMBERSHIP / ⚠️ SEMANTIC + WRITER CLAIMS REMAIN EVIDENCE-GATED

SO registry presence is canonical product integration only. Do not convert it into universal SO semantic identity, format parity or writer authority without dedicated evidence.

SHW boundary

Status: ✅ STRUCTURAL READER / ❌ WRITER OPEN

Matrix-palette ownership, universal revision coverage and authored-resource original-game acceptance remain open.

L3 blockers

B-L3-01 — Current-main R1 promotion

Status: ⚠️ RESEARCH EXISTS / PROMOTION OPEN

B-L3-02 — Family/backing ownership

Status: ❌ OPEN

B-L3-03 — Scheduler terminal dependency

Status: ❌ FRESH BOUNDED PASS REQUIRED

Targets remain 0x1402EF4D0, 0x1402EF790, 0x1400333E0, 0x140033390, 0x1400335A0, 0x1402EF460, with 0x1401B8DC0 as regression anchor.

B-L3-04 — V1–V7 original-process receipts

Status: ❌ OPEN

B-L3-05 — Final L3 audit

Status: ❌ OPEN

  • SCM real size-changing canonical rebuild + real PAC packed reflow/reopen receipt (#386 branch evidence);
  • MOT canonical registry membership plus parser/IR/key-evaluation consolidation (#372 for the parser/IR and evaluation slice);
  • bounded compression-3 cached search + normal T/R/S channel/motion-group scalar bridge on reverse/mod-completion-20260907;
  • SO graph/volume/link canonical registry membership.

Current access boundary

Trusted protected-process/install observations required for remaining L1/L2/L3 original-process gates are still missing. Static/corpus/product evidence must not be upgraded into original-runtime acceptance.
