### AI metadata tooling
The AI metadata store under `ai/metadata/` comes with a helper CLI to
validate package records against the JSON schema and regenerate
`index.json` after adding new entries:
```bash
cargo run --bin metadata_indexer -- --base-dir . validate
cargo run --bin metadata_indexer -- --base-dir . index
```
Use `--compact` with `index` if you prefer single-line JSON output.
To draft metadata for a specific book page, you can run the harvest mode.
It fetches the XHTML, scrapes the build commands, and emits a schema-
compliant JSON skeleton (pass `--dry-run` to inspect the result without
writing to disk):
```bash
cargo run --bin metadata_indexer -- \
--base-dir . harvest \
--book mlfs \
--page chapter05/binutils-pass1 \
--dry-run
```
Keep the jhalfs manifests current with:
```bash
cargo run --bin metadata_indexer -- --base-dir . refresh
```
Passing `--books mlfs,blfs` restricts the refresh to specific books, and
`--force` bypasses the local cache.
To materialise a Rust module from harvested metadata:
```bash
cargo run --bin metadata_indexer -- \
--base-dir . generate \
--metadata ai/metadata/packages/mlfs/binutils-pass-1.json \
--output target/generated/by_name
```
Add `--overwrite` to regenerate an existing module directory.
## 📚 Documentation
- [Architecture Overview](docs/ARCHITECTURE.md) – high-level tour of the crate
layout, binaries, and supporting modules.
- [Metadata Harvesting Pipeline](docs/METADATA_PIPELINE.md) – how the metadata
indexer produces and validates the JSON records under `ai/metadata/`.
- [Package Module Generation](docs/PACKAGE_GENERATION.md) – end-to-end guide
for converting harvested metadata into Rust modules under `src/pkgs/by_name/`.
- `ai/notes.md` – scratchpad for ongoing research tasks (e.g., deeper jhalfs
integration).

# Repository Context Snapshot
- `README.md`, `docs/ARCHITECTURE.md`, and `docs/METADATA_PIPELINE.md` describe
the crate structure, CLI entry points, and metadata workflows. Consult them
first when revisiting the project.
- `metadata_indexer` now supports a `refresh` command that pulls jhalfs
`wget-list`/`md5sums` manifests into `ai/metadata/cache/` and the `harvest`
command automatically draws URLs and checksums from those manifests. A
`generate` subcommand consumes harvested metadata and scaffolds Rust modules
under `src/pkgs/by_name` (or a custom output directory). See
`docs/PACKAGE_GENERATION.md` for the CLI flow.
- AI state lives under `ai/`:
- `ai/personas.json`, `ai/tasks.json`, `ai/bugs.json` track personas,
outstanding work, and known issues.
- `ai/metadata/` stores package records plus the JSON schema.
- `ai/notes.md` captures ongoing research ideas (e.g., deeper BLFS/GLFS
manifest coverage).
- Duplicate MLFS metadata entries were pruned (`binutils-pass1.json` removed in
favour of the `binutils-pass-1.json` slug).
This file is intended as a quick orientation checkpoint alongside the richer
architecture docs.

# Integrating jhalfs Source Metadata
- Goal: reuse jhalfs wget-list and md5sums to populate package `source.urls` and
auto-fill checksums when harvesting metadata for MLFS/BLFS/GLFS packages.
- Data source: `https://anduin.linuxfromscratch.org/` hosts per-release
`wget-list`/`md5sums` files already curated by the jhalfs project.
- Approach:
1. Fetch (and optionally cache under `ai/cache/`) the lists for each book.
2. When harvesting, map `<package>-<version>` against the list to gather all
relevant URLs.
3. Pull matching checksum entries to populate `source.checksums`.
4. Keep the existing HTML scrape for chapter/stage text; jhalfs covers only
sources.
- Benefits: avoids fragile HTML tables, keeps URLs aligned with official build
scripts, and ensures checksums are up-to-date.
# Metadata → Rust Module Strategy
Goal: emit Rust modules under `src/pkgs/by_name` directly from harvested
metadata once MLFS/BLFS/GLFS records are validated.
Outline:
1. **Schema alignment** – Ensure harvested JSON carries everything the
`PackageDefinition` constructor expects (source URLs, checksums, build
commands, dependencies, optimisation flags, notes/stage metadata).
2. **Translation layer** – Implement a converter (likely in a new module,
e.g. `src/pkgs/generator.rs`) that reads a metadata JSON file and produces a
`ScaffoldRequest` or directly writes the module source via the existing
scaffolder.
3. **Naming/layout** – Derive module paths from `package.id` (e.g.
`mlfs/binutils-pass-1` → `src/pkgs/by_name/bi/binutils/pass_1/mod.rs`) while
preserving the prefix/slug conventions already used by the scaffolder.
4. **CLI integration** – Add a subcommand (`metadata_indexer generate`) that
accepts a list of package IDs or a glob, feeds each through the translator,
and optionally stages the resulting Rust files.
5. **Diff safety** – Emit modules to a temporary location first, compare
against existing files, and only overwrite when changes are detected; keep a
`--dry-run` mode for review.
6. **Tests/checks** – After generation, run `cargo fmt` and `cargo check` to
ensure the new modules compile; optionally add schema fixtures covering edge
cases (variants, multiple URLs, absent checksums).
Open questions:
- How to represent optional post-install steps or multi-phase builds inside the
generated module (additional helper functions vs. raw command arrays).
- Where to store PGO workload hints once the PGO infrastructure is defined.

# Architecture Overview
This project is split into a reusable Rust library crate (`package_management`)
and several binaries that orchestrate day-to-day workflows. The sections below
outline the main entry points and how the supporting modules fit together.
## CLI entry points
| Binary | Location | Purpose |
| ------ | -------- | ------- |
| `lpkg` | `src/main.rs` | Primary command-line interface with workflow automation and optional TUI integration. |
| `metadata_indexer` | `src/bin/metadata_indexer.rs` | Harvests LFS/BLFS/GLFS package metadata, validates it against the JSON schema, keeps `ai/metadata/index.json` up to date, and can scaffold Rust modules from harvested records. |
### `lpkg` workflows
`lpkg` uses [Clap](https://docs.rs/clap) to expose multiple subcommands:
- `EnvCheck` – fetches `<pre>` blocks from an LFS-style HTML page and runs the
embedded `ver_check` / `ver_kernel` scripts.
- `FetchManifests` – downloads the book’s canonical `wget-list` and `md5sums`
files and writes them to disk.
- `BuildBinutils` – parses the Binutils Pass 1 page, mirrors the documented
build steps, and executes them in a Tokio runtime.
- `ScaffoldPackage` – generates a new module under `src/pkgs/by_name/` with
optimisation defaults (LTO/PGO/`-O3`) and persists metadata via the DB
helpers.
- `ImportMlfs` – walks the MLFS catalogue, scaffolding definitions and storing
them in the database (with optional `--dry-run`, `--limit`, and `--overwrite`).
When compiled with the `tui` feature flag, the CLI also exposes
`lpkg tui disk-manager`, which drops the user into the terminal UI defined in
`src/tui/`.
### `metadata_indexer`
The `metadata_indexer` binary is a companion tool for maintaining the JSON
artifacts under `ai/metadata/`:
- `validate` – validates every `packages/**.json` file against
`ai/metadata/schema.json` and reports schema or summary extraction issues.
- `index` – revalidates the metadata and regenerates
`ai/metadata/index.json` (use `--compact` for single-line JSON).
- `harvest` – fetches a given book page, extracts build metadata, and emits a
schema-compliant JSON skeleton. When direct HTML parsing does not locate the
source tarball, it falls back to cached jhalfs manifests to populate
`source.urls` and MD5 checksums.
- `refresh` – downloads (or re-downloads with `--force`) the jhalfs manifests
(`wget-list`, `md5sums`) for one or more books and stores them under
`ai/metadata/cache/`.
## Module layout
```
src/
ai/ // JSON loaders for repository personas, tasks, and bugs
db/ // Diesel database setup and models
html.rs // Lightweight HTML helpers (fetch + parse <pre> blocks)
ingest/ // Parsers for LFS / MLFS / BLFS / GLFS book content
md5_utils.rs // Fetches canonical md5sums from the book mirror
mirrors.rs // Lists official source mirrors for downloads
pkgs/ // Package scaffolding and metadata definition helpers
tui/ // Optional terminal UI (crossterm + tui)
version_check.rs// Executes ver_check / ver_kernel snippets
wget_list.rs // Fetches jhalfs-maintained wget-list manifests
bin/metadata_indexer.rs // AI metadata CLI described above
```
### Notable modules
- **`src/pkgs/scaffolder.rs`**
- Generates filesystem modules and `PackageDefinition` records based on a
`ScaffoldRequest`.
- Normalises directory layout (prefix modules, `mod.rs` entries) and applies
optimisation defaults (LTO, PGO, `-O3`).
- **`src/ingest/`**
- Provides HTML parsers tailored to each book flavour (LFS, MLFS, BLFS,
GLFS). The parsers emit `BookPackage` records consumed by the scaffolder
and metadata importer.
- **`src/db/`**
- Diesel models and schema for persisting package metadata. `lpkg` uses these
helpers when scaffolding or importing packages.
- **`src/tui/`**
- Houses the optional terminal interface (disk manager, main menu, settings,
downloader). The entry points are conditionally compiled behind the `tui`
cargo feature.
## Data & metadata assets
The repository keeps long-lived ARTifacts under `ai/`:
- `ai/metadata/` – JSON schema (`schema.json`), package records, and a generated
index (`index.json`). The `metadata_indexer` binary maintains these files.
- `ai/personas.json`, `ai/tasks.json`, `ai/bugs.json` – contextual data for
automated assistance.
- `ai/notes.md` – scratchpad for future work (e.g., jhalfs integration).
`data/` currently contains catalogues derived from the MLFS book and can be
extended with additional book snapshots.
## Database and persistence
The Diesel setup uses SQLite (via the `diesel` crate with `sqlite` and `r2d2`
features enabled). Connection pooling lives in `src/db/mod.rs` and is consumed
by workflows that scaffold or import packages.
## Optional terminal UI
The TUI resolves around `DiskManager` (a crossterm + tui based interface for
GPT partition inspection and creation). Additional stubs (`main_menu.rs`,
`settings.rs`, `downloader.rs`) are present for future expansion. The main CLI
falls back to `DiskManager::run_tui()` whenever `lpkg` is invoked without a
subcommand and is compiled with `--features tui`.

# Metadata Harvesting Pipeline
This repository tracks AI-friendly package metadata under `ai/metadata/`.
The `metadata_indexer` binary orchestrates validation and harvesting tasks.
This document explains the workflow and the supporting assets.
## Directory layout
- `ai/metadata/schema.json` – JSON Schema (Draft 2020-12) describing one
package record.
- `ai/metadata/packages/<book>/<slug>.json` – harvested package metadata.
- `ai/metadata/index.json` – generated summary table linking package IDs to
their JSON files.
- `ai/notes.md` – scratchpad for future improvements (e.g., jhalfs integration).
## `metadata_indexer` commands
| Command | Description |
| ------- | ----------- |
| `validate` | Loads every package JSON file and validates it against `schema.json`. Reports schema violations and summary extraction errors. |
| `index` | Re-runs validation and regenerates `index.json`. Use `--compact` to write a single-line JSON payload. |
| `harvest` | Fetches a book page, scrapes build instructions, and emits a draft metadata record (to stdout with `--dry-run` or into `ai/metadata/packages/`). Falls back to jhalfs manifests when inline source links are absent. |
| `refresh` | Updates cached jhalfs manifests (`wget-list`, `md5sums`) under `ai/metadata/cache/`. Supports `--books` filtering and `--force` to bypass the cache. |
| `generate` | Translates harvested metadata into Rust modules under `src/pkgs/by_name` (or a specified directory), using the scaffolder to create `PackageDefinition` wrappers. |
### Harvesting flow
1. **Fetch HTML** – the requested page is downloaded with `reqwest` and parsed
using `scraper` selectors.
2. **Heading metadata** – the `h1.sect1` title provides the chapter/section,
canonical package name, version, and optional variant hints.
3. **Build steps** – `<pre class="userinput">` blocks become ordered `build`
phases (`setup`, `configure`, `build`, `test`, `install`).
4. **Artifact stats** – `div.segmentedlist` entries supply SBU and disk usage.
5. **Source URLs** – the harvester tries two strategies:
- Inline HTML links inside the page (common for BLFS articles).
- Fallback to the cached jhalfs `wget-list` for the selected book to find
matching `<package>-<version>` entries.
6. **Checksums** – the matching entry from the cached jhalfs `md5sums`
manifest populates `source.checksums` when the archive name is known.
7. **Status** – unresolved items (missing URLs, anchors, etc.) are recorded in
`status.issues` so humans can interrogate or patch the draft before
promoting it.
### Known gaps
- **Source links via tables** – some MLFS chapters list download links inside a
“Package Information” table. The current implementation relies on the
jhalfs `wget-list` fallback instead of parsing that table.
- **Anchor discovery** – if the heading lacks an explicit `id` attribute, the
scraper attempts to locate child anchors or scan the raw HTML. If none are
found, a warning is recorded and `status.issues` contains a reminder.
## Using jhalfs manifests
The maintained `wget-list`/`md5sums` files hosted by jhalfs provide canonical
source URLs and hashes. The `metadata_indexer refresh` command keeps these
manifests cached under `ai/metadata/cache/`. Harvesting consumes the cached
copies to populate URLs and MD5 checksums.
Planned enhancements (see `ai/notes.md` and `ai/bugs.json#metadata-harvest-no-source-urls`):
1. Abstract list fetching so BLFS/GLFS variants can reuse the logic.
2. Normalise the match criteria for package + version (handling pass stages,
suffixes, etc.).
## Manual review checklist
When a new metadata file is generated:
- `schema_version` should match `schema.json` (currently `v0.1.0`).
- `package.id` should be unique (format `<book>/<slug>`).
- `source.urls` must include at least one primary URL; add mirrors/patches as
needed.
- Clear any `status.issues` before promoting the record from `draft`.
- Run `cargo run --bin metadata_indexer -- --base-dir . index` to regenerate
the global index once the draft is finalised.
Refer to `README.md` for usage examples and to `docs/ARCHITECTURE.md` for a
broader overview of the crate layout.

# Package Module Generation
This document explains how harvested metadata is transformed into concrete
Rust modules under `src/pkgs/by_name/`.
## Overview
1. **Harvest metadata** – Use `metadata_indexer harvest` to capture package data
from the LFS/BLFS/GLFS books. Each record is written to
`ai/metadata/packages/<book>/<slug>.json`.
2. **Refresh manifests** – Run
`metadata_indexer refresh` to ensure the jhalfs `wget-list` and `md5sums`
caches are up to date. Harvesting relies on these caches for canonical
source URLs and checksums.
3. **Generate modules** – Use
`metadata_indexer generate --metadata <path> --output <by_name_dir>` to turn a
metadata file into a full Rust module that exposes a `PackageDefinition`.
Generated modules leverage the existing scaffolder logic, so the command will
create any missing prefix directories (e.g. `bi/mod.rs`) and populate the final
`mod.rs` file with the correct code template.
## Command reference
```bash
# Harvest metadata from a book page
cargo run --bin metadata_indexer -- --base-dir . harvest \
--book mlfs \
--page chapter05/binutils-pass1 \
--output ai/metadata/packages/mlfs/binutils-pass-1.json
# Refresh jhalfs manifests (optional but recommended)
cargo run --bin metadata_indexer -- --base-dir . refresh
# Generate a module under the standard src tree
cargo run --bin metadata_indexer -- --base-dir . generate \
--metadata ai/metadata/packages/mlfs/binutils-pass-1.json \
--output src/pkgs/by_name \
--overwrite
```
### Flags
- `--output` defaults to `src/pkgs/by_name`. Point it to another directory if
you want to stage modules elsewhere (e.g. `target/generated/by_name`).
- `--overwrite` deletes the existing module directory before scaffolding a new
one.
After generation, run `cargo fmt` and `cargo check` to ensure the crate compiles
with the new modules.
## Implementation notes
- Metadata fields such as `build`, `dependencies`, and `optimizations` are
mapped directly onto the scaffolder’s `ScaffoldRequest` type.
- Source URLs and MD5 checksums are sourced from the harvested metadata
(populated via the jhalfs manifests).
- The module slug is derived from `package.id` (e.g.
`mlfs/binutils-pass-1` → `src/pkgs/by_name/bi/binutils_pass_1/mod.rs`).
See the code in `src/pkgs/generator.rs` for the full translation logic.
