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, and keeps `ai/metadata/index.json` up to date. | + +### `lpkg` workflows + +`lpkg` uses [Clap](https://docs.rs/clap) to expose multiple subcommands: + +- `EnvCheck` – fetches `
` 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 the jhalfs `wget-list` data to populate
+  `source.urls`.
+
+## 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 
 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//.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/`). |
+
+### 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** – `
` 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 jhalfs `wget-list` for the selected book (currently MLFS)
+     using `package-management::wget_list::get_wget_list` to find matching
+     `-` entries.
+6. **Checksums** – integration with the book’s `md5sums` mirror is pending;
+   placeholder wiring exists (`src/md5_utils.rs`).
+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
+  β€œPackage Information” table. The current implementation relies on the
+  jhalfs `wget-list` fallback instead of parsing that table.
+- **Checksums** – MD5 lookups from jhalfs are planned but not yet wired into
+  the harvest pipeline.
+- **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 helper modules `src/wget_list.rs` and
+`src/md5_utils.rs` download these lists for the multilib LFS book. The
+harvester currently consumes the wget-list as a fallback; integrating the
+`md5sums` file will let us emit `source.checksums` automatically.
+
+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.).
+3. Populate checksum entries alongside URLs.
+
+## 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 `/`).
+- `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.

 The maintained `wget-list`/`md5sums` files hosted by jhalfs provide canonical
-source URLs and hashes. The helper modules `src/wget_list.rs` and
-`src/md5_utils.rs` download these lists for the multilib LFS book. The

+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.).
-3. Populate checksum entries alongside URLs.

+  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.
+- 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.

 - Benefits: avoids fragile HTML tables, keeps URLs aligned with official build

+
+# Metadata β†’ 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` β†’ `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.

 | `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. |

+# 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` β†’ `src/pkgs/by_name/bi/binutils_pass_1/mod.rs`).
+
+See the code in `src/pkgs/generator.rs` for the full translation logic.
