              represent, as a whole, an original work of authorship. For the purposes
              of this License, Derivative Works shall not include works that remain
              separable from, or merely link (or bind by name) to the interfaces of,
              the Work and Derivative Works thereof.
        
              "Contribution" shall mean any work of authorship, including
              the original version of the Work and any modifications or additions
              to that Work or Derivative Works thereof, that is intentionally

              "Contributor" shall mean Licensor and any individual or Legal Entity
              on behalf of whom a Contribution has been received by the Licensor and
              subsequently incorporated within the Work.
        
           2. Grant of Copyright License. Subject to the terms and conditions of
              this License, each Contributor hereby grants to You a perpetual,
              worldwide, non-exclusive, no-charge, royalty-free, irrevocable
              copyright license to reproduce, prepare Derivative Works of,
              publicly display, publicly perform, sublicense, and distribute the
              Work and such Derivative Works in Source or Object form.
        
           3. Grant of Patent License. Subject to the terms and conditions of
              this License, each Contributor hereby grants to You a perpetual,
              worldwide, non-exclusive, no-charge, royalty-free, irrevocable
              (except as stated in this section) patent license to make, have made,
              use, offer to sell, sell, import, and otherwise transfer the Work,
              where such license applies only to those patent claims licensable
              by such Contributor that are necessarily infringed by their
              Contribution(s) alone or by combination of their Contribution(s)
              with the Work to which such Contribution(s) was submitted. If You
              institute patent litigation against any entity (including a
              cross-claim or counterclaim in a lawsuit) alleging that the Work
              or a Contribution incorporated within the Work constitutes direct
              or contributory patent infringement, then any patent licenses
              granted to You under this License for that Work shall terminate
              as of the date such litigation is filed.
        
           4. Redistribution. You may reproduce and distribute copies of the
              Work or Derivative Works thereof in any medium, with or without
              modifications, and in Source or Object form, provided that You
              meet the following conditions:
        
              (a) You must give any other recipients of the Work or
                  Derivative Works a copy of this License; and
        
              (b) You must cause any modified files to carry prominent notices
                  stating that You changed the files; and
        
              (c) You must retain, in the Source form of any Derivative Works
                  that You distribute, all copyright, patent, trademark, and
                  attribution notices from the Source form of the Work,
                  excluding those notices that do not pertain to any part of
                  the Derivative Works; and
        
              (d) If the Work includes a "NOTICE" text file as part of its
                  distribution, then any Derivative Works that You distribute must
                  include a readable copy of the attribution notices contained
                  within such NOTICE file, excluding those notices that do not
                  pertain to any part of the Derivative Works, in at least one
                  of the following places: within a NOTICE text file distributed
                  as part of the Derivative Works; within the Source form or
                  documentation, if provided along with the Derivative Works; or,
                  within a display generated by the Derivative Works, if and
                  wherever such third-party notices normally appear. The contents
                  of the NOTICE file are for informational purposes only and
                  do not modify the License. You may add Your own attribution
                  notices within Derivative Works that You distribute, alongside
                  or as an addendum to the NOTICE text from the Work, provided
                  that such additional attribution notices cannot be construed
                  as modifying the License.
        
              You may add Your own copyright statement to Your modifications and
              may provide additional or different license terms and conditions
              for use, reproduction, or distribution of Your modifications, or
              for any such Derivative Works as a whole, provided Your use,
              reproduction, and distribution of the Work otherwise complies with
              the conditions stated in this License.
        
           5. Submission of Contributions. Unless You explicitly state otherwise,
              any Contribution intentionally submitted for inclusion in the Work
              by You to the Licensor shall be under the terms and conditions of
              this License, without any additional terms or conditions.
              Notwithstanding the above, nothing herein shall supersede or modify
              the terms of any separate license agreement you may have executed
              with Licensor regarding such Contributions.
        
           6. Trademarks. This License does not grant permission to use the trade
              names, trademarks, service marks, or product names of the Licensor,
              except as required for reasonable and customary use in describing the
              origin of the Work and reproducing the content of the NOTICE file.
        
           7. Disclaimer of Warranty. Unless required by applicable law or
              agreed to in writing, Licensor provides the Work (and each
              Contributor provides its Contributions) on an "AS IS" BASIS,
              WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
              implied, including, without limitation, any warranties or conditions
              of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
              PARTICULAR PURPOSE. You are solely responsible for determining the
              appropriateness of using or redistributing the Work and assume any
              risks associated with Your exercise of permissions under this License.
        
           8. Limitation of Liability. In no event and under no legal theory,
              whether in tort (including negligence), contract, or otherwise,
              unless required by applicable law (such as deliberate and grossly
              negligent acts) or agreed to in writing, shall any Contributor be
              liable to You for damages, including any direct, indirect, special,
              incidental, or consequential damages of any character arising as a
              result of this License or out of the use or inability to use the
              Work (including but not limited to damages for loss of goodwill,
              work stoppage, computer failure or malfunction, or any and all
              other commercial damages or losses), even if such Contributor
              has been advised of the possibility of such damages.
        
           9. Accepting Warranty or Additional Liability. While redistributing
              the Work or Derivative Works thereof, You may choose to offer,
              and charge a fee for, acceptance of support, warranty, indemnity,
              or other liability obligations and/or rights consistent with this
              License. However, in accepting such obligations, You may act only
              on Your own behalf and on Your sole responsibility, not on behalf
              of any other Contributor, and only if You agree to indemnify,
              defend, and hold each Contributor harmless for any liability
              incurred by, or claims asserted against, such Contributor by reason
              of your accepting any such warranty or additional liability.
        
           END OF TERMS AND CONDITIONS

## 📚 Official Documentation

For complete documentation, guides, and API reference, visit **[batho.sageoz.org](https://batho.sageoz.org)**.

## 🚀 Quick Start

```bash
# Install
pip install batho / uv add batho

# Build full repository index
batho build --root .

# Exports the latest Batho artifact into a transportable ZIP by default ("artifact_<dir>.batho").
batho export --root .

# Incrementally patch changed files (using native content hashes)
batho patch --root .

# Query granular node changes between runs or for a specific file/entity
batho diff --file batho/cli/build.py

# Verify artifact health and repair integrity anomalies
batho fix --deep
```

## ✨ Key Features

- **40+ language AST parsing** — Python, TypeScript, Rust, Go, Java, and more
- **10x context compression** — Fit entire codebases into LLM context windows
- **Time Machine snapshots** — Track codebase evolution with incremental patching
- **BSG Plugin System v2** — 38 built-in plugins (28 foundation + 10 interceptors) for security, quality, and optimization
- **Single-Pass Extraction** — One parse per file; cross-file references emit contextual stubs (`EntityType.UNRESOLVED`) resolved post-extraction by ScopeManager
- **Deterministic IDs** — Position-based ID generation for stable entity tracking (no false positives from code movement)
- **Graph Optimization** — Cyclic dependency detection and orphan node pruning
- **Dependency-Aware Resolution** — CDEU module resolves stdlib and third-party symbols (pip, npm, cargo, go) via manifest parsing and live introspection
- **Symbol Resolution** — Cross-file symbol resolution with hierarchical encoding and SymbolRole tagging
- **Arrow IPC Artifact Store** — Three-blob design (agent/storage/rel views) written to `.batho/artifact/` via `BathoBundle`; zero-copy memory-mapped reads
- **BSG Store** — Persistent entity/relationship graph in `.batho/bsg/current/` via `BsgScratchStore`; streaming flush + compaction for large repos
- **File Changelog** — Node-level diff history tracking per run
- **Integrity Verification** — Multi-stage fix command with auto-repair capabilities
- **Zero code execution** — Safe to run in CI or on untrusted repos

## 🛠️ CLI Commands & Usage

Batho provides a clean command-line interface:

### 1. Build Index (`batho build`)
Parses all repository source files and builds the initial AST code graph database.
```bash
batho build --root .
```
- `--full`: Force a full rebuild by deleting the existing database first.
- `--max-workers <N>`: Maximum parallel workers for parsing (defaults to CPU count).
- `--max-file-size-kb <KB>`: Skip files exceeding this size (default: 500 KB).

### 2. Incremental Patch (`batho patch`)
Scans the filesystem for modified/added files, re-parses them, and updates the index using copy-on-write database transactions.
```bash
batho patch --root .
```
- `--max-file-size-kb <KB>`: Skip files exceeding this size during hash scans.

### 3. Export (`batho export`)
Exports the latest BSG artifact into a transportable ZIP by default (`<root>/artifact_<dir>.batho`). Use `--json` to export a JSON view instead (default: `<root>/batho_export.json`).
```bash
batho export --root .
```
- `--root <path>`: Repository root directory (default: `.`).
- `--json`: Export a JSON view instead of the default transport ZIP artifact.
- `--view <view>`: JSON view format (default: `storage` with `--json`): `storage`, `agent`, `overview`, `files`, `symbols`, `dependencies`, `delta`, `rel`.
- `--output <path>`: Custom file path.
- `--filter <glob>`: Narrow exported files (e.g. `src/**/*.py`).
- `--category <category>`: Filter by code category (`source`, `test`, `doc`, `config`, `infra`, `all`).
- `--token-budget <N>`: Maximum token budget for agent view.
- `--baseline <path>`: Baseline export file (required for `delta` view).
- `--rel`: Include relationship lists in the export.
- `--index-id <ID>`: Export a specific index run UUID (default: latest).
- `--format <format>`: JSON output format (`json` or `pretty`; default: `json`).

### 4. Database Integrity (`batho fix`)
Performs multi-stage database verification (`db` → `state` → `blobs` → `graph`) and executes repair routines.
```bash
batho fix --deep
```
- `--deep`: Full validation (decompresses and checks zstd payload blobs).
- `--dry-run`: Diagnoses issues without committing repairs.
- `--target <target>`: Target a specific checker (`db`, `state`, `blobs`, `graph`, `all`).
- `--phase <1-4>`: Run a specific verification phase.
- `--parallel`: Run independent checks concurrently.
- `--format <text|json|csv>`: Report format.

### 5. Node History (`batho diff`)
Queries exact, granular changes across runs, files, or specific symbols.
```bash
batho diff --file batho/cli/build.py
```
- `--run <run_uuid>`: Changes made in a specific run.
- `--entity <entity_id>`: Full evolution history of a symbol.
- `--file <rel_path>`: All node-level changes in a file across runs.
- `--since <run_uuid>`: Bounded history start (only with `--entity`).
- `--json`: Format output as JSON.

### 6. Storage Maintenance (`batho gc`)
Manages database runs, prunes old history, and vacuums database pages.
```bash
batho gc vacuum
```
- `run <run_uuid>`: Delete a specific indexing run.
- `runs --older-than <days>`: Prune runs older than a threshold.
- `status`: Display storage metrics.
- `vacuum`: Reclaim disk space.

## 🔄 Migration from v1 to v1.1.0

**Breaking Changes:**

1. **Unified Configuration** — All config is now in a single `batho.yaml` file
   - Old: Multiple config files scattered across the codebase
   - New: Single `batho.yaml` with all settings (indexer, bsg, rules, storage)
   - Action: Delete old config files; run `batho build` to auto-generate `batho.yaml`

2. **Storage format** — SQLite `.batho` artifact replaced by Apache Arrow IPC
   - Old: `artifact_<dirname>.batho` SQLite database
   - New: `.batho/artifact/*.ipc` + `.batho/bsg/current/*.ipc` (Arrow IPC files)
   - Action: Run `batho build --root . --full` to rebuild from scratch

3. **Config key rename** — `paths.db_path` removed; replaced by `paths.artifact_dir`
   - Old: `paths.db_path: "{root}"`
   - New: `paths.artifact_dir: .batho/artifact` (env: `BATHO_ARTIFACT_DIR`)
   - Action: Remove `db_path` from your `batho.yaml`; add `artifact_dir` if custom path needed

**New Defaults:**

- Symbol resolution is **enabled by default** (can be disabled in config)
- Arrow IPC artifact store at `.batho/artifact/` (no SQLite dependency)
- BSG plugins are **enabled by default** (38 built-in security/quality plugins)
- Parallel processing is **enabled by default** (up to 16 workers)

**Recommended Migration Steps:**

```bash
# 1. Delete old SQLite artifact (format incompatible)
rm -rf .batho/

# 2. Let Batho regenerate batho.yaml with current defaults
batho build --root .

# 3. Customize batho.yaml as needed (see docs/config.md)
```

## ⚙️ Configuration

Batho works out of the box with zero config. For production use, configure with `./batho.yaml`:

```yaml
schema_version: batho-config.v1

logging:
  level: ERROR
  quiet: false

paths:
  artifact_dir: .batho/artifact   # Arrow IPC artifact store (override: BATHO_ARTIFACT_DIR)
  cache_dir: .batho/cache
  bsg_dir: .batho/bsg

indexer:
  max_file_size_kb: 500
  ignore_patterns: []

flags:
  strict: false
  audit_log_enabled: true

bsg:
  cache:
    enabled: true
    max_size_mb: 1024
  symbol_resolution:
    enabled: true
  bidirectional:
    enabled: true
