# Architect-Prime / gnosis-indus-artifacts

## What This Is

**Canonical durable off-machine backup for the `Zer0pa/Indus-Valley`
lane (Gnosis Indus anchor application and evidence repo).**

This repo is the off-machine custody surface for everything of value
in the Indus-Valley lane. The working assumption is that the local
Mac is unstable and may become unrecoverable at any moment;
`Zer0pa/Indus-Valley` (GitHub) plus this repo together must be
sufficient to reproduce the lane end to end.

Per `GNOSIS_HF_STORAGE_EXECUTION_BRIEF_2026-04-26.md` §1.2
(`Architect-Prime/*` is the canonical heavy store for Gnosis) and the
2026-04-27 operational-safety direction (no Zer0pa-org HF storage for
this lane).

## Contents

This repo is composed of three layers, two of which were laid down
earlier on 2026-04-26 by a portfolio-level safety pass and one of
which is the source-mirror layer added on 2026-04-27.

### Layer A — workspace backup (pre-existing, 2026-04-26)

| Path | Size | Description |
|---|---:|---|
| `backups/2026-04-27/indus_workspace_artifacts_2026-04-27.tar.zst` | 5.6 MB | Compressed Indus workspace artifact bundle (zstd). SHA-256 recorded in `backups/2026-04-27/LANE_CHECKSUMS.sha256`. |
| `backups/2026-04-27/LANE_CHECKSUMS.sha256` | 719 B | SHA-256 manifest covering the 2026-04-27 portfolio backup pass; lists this repo's `indus_workspace_artifacts_2026-04-27.tar.zst` plus sibling-lane artifacts under their own AP repos. |

### Layer B — GitHub source mirror (new, 2026-04-27)

| Path | Size | Description |
|---|---:|---|
| `Indus-Valley-source-023a14e91155.tar.gz` | 113 KB | `git archive` tarball of `Zer0pa/Indus-Valley@023a14e91155` (the consuming GitHub repo's HEAD at last sync). Restorable with `tar xzf`. |
| `repo/` | 90 files | Uncompressed mirror of the same HEAD. Includes the full `authority/` bundle, the Phase 4 demo fixture under `artifacts/phase4/`, the Phase 02 runtime under `src/gnosis_indus/`, the pytest suite under `tests/`, all `.gpd/` control-plane state, the `.github/` CI workflow, and every front-door doc. |

### Layer C — top-level files

| Path | Description |
|---|---|
| `README.md` | this card |
| `MANIFEST.txt` | machine-readable inventory of layers A + B |

## What This Proves

- **Operational durability.** Every artifact considered valuable for
  the Indus-Valley lane is present on at least two off-machine
  surfaces (GitHub `Zer0pa/Indus-Valley` for source / docs / state;
  this repo for the same source plus the workspace artifact backup).
- **Provenance integrity.** The source-mirror layer is a `git
  archive` of a named commit and is byte-equivalent to GitHub HEAD at
  that commit. The workspace artifact backup has a SHA-256 in
  `LANE_CHECKSUMS.sha256`.
- **Carved-out caveats survive.** The Phase 4 k=70 stability caveat
  and the Phase 5 non-decipherment posture, as carried in the
  authority bundle, are preserved verbatim under `repo/authority/`.

## What This Does Not Claim

- **No decipherment.** Cluster IDs are morphological groupings only.
- **No image-bearing redistribution.** Raw sign images are
  `BLOCKED_RIGHTS` per the consuming repo's `DATA_POLICY.md`. No
  image bytes are uploaded here.
- **No public open-source license.** Private internal Architect-Prime
  repo. Legal posture set by `Zer0pa/Indus-Valley`'s `NOTICE.md`.
- **Not the full k=70 catalogue.** The full Phase 4 catalogue (412
  signs, 70 clusters, 179 inscriptions) is `FETCH_EXTERNAL` per
  `DATA_POLICY.md`. Only the authority-anchored demo fixture is
  bundled.
- **The `indus_workspace_artifacts_2026-04-27.tar.zst` predates this
  agent.** It was uploaded on 2026-04-26 by a portfolio-level safety
  pass; this card documents its presence but does not unilaterally
  modify or replace it.

## Source

- **Consuming GitHub repo:** `Zer0pa/Indus-Valley`
  (`https://github.com/Zer0pa/Indus-Valley`)
- **GitHub HEAD at last sync:** `023a14e91155` (full SHA recorded in
  `MANIFEST.txt` and tarball filename).
- **Custody register:** `HF_CUSTODY_REGISTER.md` at the consuming
  GitHub repo root is authoritative when this card and the register
  disagree.

## Recovery procedure (Mac dies scenario)

**From GitHub (preferred):**

```
git clone https://github.com/Zer0pa/Indus-Valley.git
cd Indus-Valley
python3.11 -m venv .venv && source .venv/bin/activate
pip install -e '.[test,numerics]'
pytest -q       # expected: 14 passed
```

**From this AP repo (if GitHub access is also disrupted):**

```
pip install huggingface_hub
python3 -c "
from huggingface_hub import hf_hub_download
p = hf_hub_download(
    repo_id='Architect-Prime/gnosis-indus-artifacts',
    repo_type='dataset',
    filename='Indus-Valley-source-023a14e91155.tar.gz',
)
print(p)"
tar xzf Indus-Valley-source-023a14e91155.tar.gz
cd Indus-Valley-023a14e91155
python3.11 -m venv .venv && source .venv/bin/activate
pip install -e '.[test,numerics]'
pytest -q       # expected: 14 passed
```

The workspace-artifact backup
(`backups/2026-04-27/indus_workspace_artifacts_2026-04-27.tar.zst`) is
recoverable with `zstd -d`; verify against
`backups/2026-04-27/LANE_CHECKSUMS.sha256` first.

## Sync protocol

When `Zer0pa/Indus-Valley` advances on GitHub:

1. From a clean checkout of the new HEAD, build a fresh
   `Indus-Valley-source-<sha12>.tar.gz` via
   `git archive --format=tar.gz --prefix=Indus-Valley-<sha12>/ -o ... HEAD`.
2. Upload the tarball and refresh the uncompressed `repo/` mirror.
3. Update `MANIFEST.txt` and the consuming repo's
   `HF_CUSTODY_REGISTER.md` with the new SHA.
4. Leave `backups/` alone unless explicitly directed; it is a
   portfolio-pass surface.

## Visibility Rationale

**Private (must remain so).** Per
`GNOSIS_HF_STORAGE_EXECUTION_BRIEF_2026-04-26.md` §1.3 +
"Non-Negotiables" §8 ("never make an Architect-Prime Gnosis repo
public"). The repo holds full source, authority verdict copies,
state, and a workspace artifact backup.

## License Or Access Posture

No public license is granted. Use is restricted to Zer0pa and its
explicitly briefed internal collaborators. The legal posture is set
by the consuming GitHub repo's `NOTICE.md`:
