# D23 Reviewer Bundle V2 And ITHKOR-SIM Pivot

Status:

```text
D23_REVIEWER_BUNDLE_V2_READY__BRANCH_CLOSURES_AND_SIM_PIVOT_DOCUMENTED__NO_PHYSICAL_CLAIM
```

D23 is a documentation and reviewer-hardening step. It does not replace D20,
does not edit the D20 manifest, does not submit QPU jobs, and does not upgrade
finite diagnostics into physics. It adds a current branch-closure layer and a
new practical research direction: ITHKOR-SIM.

Raw D23 outputs:

## Reviewer V2 Set

The reviewer V2 set is broader than D20. It keeps the original reviewer
discipline while adding E/F quantum-to-macro rows and the latest CGR/TGR
closure state.

| Row | Role | Rerun Policy | Why It Is Included |
| --- | --- | --- | --- |
| `C3B_V011_PROBE_BUDGETED_N12` | selector witness | local rerun allowed | Checks the C/kernel stabilizing selector. |
| `D7B_PLANCK_CAPACITY_QPU` | finite threshold QPU readout | QPU explicit-approval-only | Keeps a frozen finite QPU threshold row. |
| `D10F_SOURCE_RESPONSE_QPU` | finite source-response QPU readout | QPU explicit-approval-only | Keeps a frozen finite field/readout row. |
| `E2_CONTEXTUAL_READOUT` | quantum-information row | QPU explicit-approval-only for hardware repeats | Shows finite contextual readout support. |
| `F_CLASSICAL_RECORD_STABILITY` | macro-record layer | local/Aer rerun allowed | Connects quantum readout to stable public records. |
| `COND3_PHASE_DIAGRAM` | coherent-order island | local rerun allowed | Shows finite coherent-order scope and boundary. |
| `GR3_HELDOUT_DECOMPOSITION` | modular response | local rerun allowed | Shows finite modular-response scope. |
| `TIME2C_DARK_ENTROPY_SCOPE` | internal-clock row | local rerun allowed | Shows scoped dark/entropy internal ordering. |
| `CGR_SERIES_CLOSURE` | COND/GR closure | local rerun allowed | Shows latest scoped response-pattern closure. |
| `TGR3_RECURRENCE_TAXONOMY` | TIME/GR boundary row | local rerun allowed | Shows recurrence leak localization without repair. |
| `MOD1_NEGATIVE_TAXONOMY` | negative row | local rerun allowed; must remain fail | Protects against success-only packaging. |
| `ISLANDS1_META_AUDIT` | meta-audit | local rerun allowed | Shows island/boundary map, not physics. |

## What Changed Since D20

D20 froze a representative reviewer bundle. D21 checked the bundle for clean
use. D22 reran non-QPU rows and recorded drift. D23 adds:

- a branch-closure ledger after CGR/TGR;
- E/F quantum-to-macro status in the reviewer-facing map;
- latest COND/GR/TIME bridge boundaries;
- an explicit ITHKOR-SIM practical research pivot.

## Claim Boundary

Allowed:

```text
D23 documents the current finite research state and prepares a practical
information-adaptive simulation research program.
```

Blocked:

```text
D23 does not confirm physical spacetime, physical time, gravity, quantum
gravity, material superfluidity, or General ITHKOR.
```

## Practical Next Step

The next work should not attempt to force blocked physical bridges. It should
ask whether the verified finite diagnostics have practical value:

- adaptive level of detail from coherent-mode pressure;
- compute allocation from source-response fields;
- checkpoint placement from stable public records;
- event scheduling from scoped dark/entropy internal ordering;
- compression from negative-control-aware information pressure.

## Later SIM2C/SIM3C Practical Pass Layer

D23 opened the SIM pivot. Later SIM2/SIM3 follow-up work refined that pivot:

- SIM2/SIM2B remain boundary results for bare checkpoint placement.
- SIM3/SIM3B remain boundary results for mask-only or hybrid detail
  compression.
- SIM2C passes temporal-jet checkpoint records in 3/3 counted structured toy
  worlds.
- SIM3C passes observable-capsule compression in 3/3 counted structured toy
  worlds.

This upgrades the practical pilot scope, not the physical claim scope. The
allowed next step is a real or semi-real simulation benchmark that tests:

1. adaptive update budgets from SIM1/SIM4;
2. temporal-jet checkpoint records from SIM2C;
3. observable-capsule compression from SIM3C;
4. uniform/domain-native, source/gradient, random and shuffled controls.

Stress/noise rows remain separate. No QPU was run for SIM2C/SIM3C, and no
claim is added about physical correctness, spacetime, gravity, quantum gravity
or the universe being a simulation.
