# CACP / Costly Escalation source archive

This is one integrated codebase within the Logos Execution Zone monorepo.
`source/` preserves all 18 changed files from
[PR #704](https://github.com/logos-blockchain/logos-execution-zone/pull/704),
including the built bond-program artifact, manifests, lockfile, entry point,
and test-fixture integration. Every file is exported directly from commit
`b7154ba2bf1d456d544da74b61b9b2149298403e`.

The complete change set comprises eight commits. Their hashes and subjects,
source blob IDs, file sizes and SHA-256 checksums are in [provenance.json](provenance.json).

## Implementation map

| Files in `source/` | Role |
| --- | --- |
| `lez/cross_zone/src/cacp.rs` | CACP state machine, exact funded-transaction and proof checks, fallback and reference tests. |
| `lez/cross_zone/src/costly_abort.rs` | Costly Escalation reference adapter and tests; historical filename retained. |
| `lez/programs/cacp_bond/core/` | Agreement schema and IDs, account derivation, state/settlement helpers and core tests. |
| `lez/programs/cacp_bond/src/main.rs` | Executable neutral-zone bond program, authorization, escrow validation, disclosure and settlement. |
| `tools/cacp_demo/` | Live local network harness, scenario assertions and demo instructions. |
| `artifacts/lez/programs/cacp_bond.bin` | Committed RISC Zero guest executable used by the source revision. |
| Cargo manifests, `Cargo.lock`, `Justfile`, program exports and initial-state integration | Connect the new components to the surrounding LEZ workspace. |

## Obtain the full runnable workspace

```sh
git clone https://github.com/Warrenhimself/logos-execution-zone.git lez-cacp
cd lez-cacp
git checkout --detach b7154ba2bf1d456d544da74b61b9b2149298403e
```

Follow that checkout's root README and toolchain/dependency setup. This archive
does not vendor all upstream source, external Cargo dependencies or native
circuit libraries. Build from the full checkout, not directly from `source/`.

## Reconstruct the changes from the base

The [complete patch](patches/cacp-pr-704.patch) includes binary data and all
integration edits. To apply it, first obtain the full repository above and check
out the exact base:

```sh
git checkout --detach 03f46bf191232b43509abb2a03ed7fcc6890dcbc
git apply --check /path/to/Internships/2026/Qizhe.Jiang/Code/cacp-costly-escalation/patches/cacp-pr-704.patch
git apply --index /path/to/Internships/2026/Qizhe.Jiang/Code/cacp-costly-escalation/patches/cacp-pr-704.patch
git write-tree
git rev-parse b7154ba2bf1d456d544da74b61b9b2149298403e^{tree}
```

The last two commands must print the same tree ID. Apply this patch only to
that base; do not apply it again on top of the final source commit.

## Build and verification

From the pinned full checkout:

```sh
cargo test --locked -p cacp_bond_core --lib
cargo test --locked -p cross_zone --lib
cargo check --locked -p cacp_bond_program -p cacp_demo
just demo-cacp
```

The demo requires Docker and the upstream native/circuit dependencies. It uses
local deterministic development funds and development-mode proofs. Its success
marker is `ALL 5 LIVE CACP SCENARIOS PASSED`; this is an expected marker, not
evidence that a fresh live run was performed while creating this archive.
See [Results](../../Results/README.md) for checks actually performed.

## License and provenance

The included source and compiled artifact retain the upstream MIT license.
See the accompanying license file. The original commit is the authority for
the source snapshot; the archive does not rewrite source comments or history.
