From df74cec8bb56b67109bf614bc277e78d3d2ea9e4 Mon Sep 17 00:00:00 2001 From: Louis Choquel Date: Thu, 12 Feb 2026 02:06:56 +0100 Subject: [PATCH 01/12] Add METHODS.toml package manifest, exports/visibility model, and pkg CLI (Phase 2) Introduce the package manifest system for .mthds bundles: MthdsPackageManifest data model with TOML parsing/serialization, walk-up manifest discovery, cross-domain pipe visibility enforcement against [exports], cross-package -> reference detection, CLI commands (pipelex pkg init/list), and builder awareness for multi-domain output.

[PATCH 02/12] Add version constraints, required description, and update tests for package manifest Make description a required field on MthdsPackageManifest (no longer optional), add version constraint validation for dependencies (supporting ^, ~, >=, <=, >, <, ==, !=, comma-separated, and wildcard syntax), and update all test fixtures and invalid manifest files to include the now-required description field.

This replaced the brief's suggestion of a separate `PipeReference` class in `pipelex/core/pipes/` — the unified model eliminates duplication since concept and pipe references share the same parsing logic (split-on-last-dot, casing disambiguates). The `package_alias` field is omitted since cross-package references are Phase 3; adding it later is trivial. +- **Split-on-last-dot parsing**: unified parsing rule for both concept and pipe references — the last segment is the `local_code` (casing disambiguates pipe vs. concept), everything before it is the `domain_path`. +- **Bundle blueprint validation**: domain-qualified pipe references are validated against known domains and pipes within the current package, mirroring the existing concept reference validation pattern. +- **Builder bundles migrated**: cross-domain pipe references in the builder's internal bundles (`agentic_builder.mthds`, `builder.mthds`) now use `domain.pipe_code` syntax. +- **New tests**: positive tests for domain-qualified pipe references in sequences, and negative tests for references to non-existent domains/pipes. + +--- + +## Phase 2: Package Manifest + Exports / Visibility — COMPLETED + +Delivered: + +- **`MthdsPackageManifest` data model** (`pipelex/core/packages/manifest.py`): `PackageDependency`, `DomainExports`, and `MthdsPackageManifest` Pydantic models with field validators (address hostname pattern, semver for package version, version constraint ranges for dependency versions, non-empty description, snake_case aliases, unique aliases, valid domain paths, valid pipe codes). +- **TOML parsing and serialization** (`pipelex/core/packages/manifest_parser.py`): `parse_methods_toml()` with recursive sub-table walk for `[exports]` domain path reconstruction; `serialize_manifest_to_toml()` using `tomlkit` for human-readable output. +- **Custom exceptions** (`pipelex/core/packages/exceptions.py`): `ManifestError`, `ManifestParseError`, `ManifestValidationError`. +- **Manifest discovery** (`pipelex/core/packages/discovery.py`): `find_package_manifest()` walks up from a bundle path, stopping at `METHODS.toml`, `.git/` boundary, or filesystem root. Returns `None` for standalone bundles. +- **Visibility checker** (`pipelex/core/packages/visibility.py`): `PackageVisibilityChecker` enforces cross-domain pipe visibility against `[exports]`. Rules: no manifest = all public; bare ref = allowed; same-domain = allowed; cross-domain requires pipe to be in `[exports]` or be `main_pipe` (auto-exported). Error messages include `[exports]` hint. +- **Cross-package `->` reference detection**: `QualifiedRef.has_cross_package_prefix()` and `split_cross_package_ref()` static methods. `PackageVisibilityChecker.validate_cross_package_references()` emits warnings for known aliases, errors for unknown aliases. +- **Visibility wired into bundle loading** (`pipelex/libraries/library_manager.py`): `_check_package_visibility()` runs after blueprint parsing, before `load_from_blueprints`. Raises `LibraryLoadingError` on violations. +- **CLI commands** (`pipelex/cli/commands/pkg/`): `pipelex pkg init` scans `.mthds` files, generates skeleton `METHODS.toml` with auto-discovered domains and all pipes exported. `pipelex pkg list` finds and displays the manifest with Rich tables (package info, dependencies, exports). +- **Builder awareness** (`pipelex/builder/builder_loop.py`): `maybe_generate_manifest_for_output()` checks if an output directory contains multiple domains and generates a `METHODS.toml` if so. Hooked into both `pipe_cmd.py` and `build_core.py`. +- **Physical test data** (`tests/data/packages/`): `legal_tools/` (full manifest + multi-domain bundles), `minimal_package/` (minimal manifest), `standalone_bundle/` (no manifest), `invalid_manifests/` (6 negative test files). +- **Comprehensive tests**: 45+ new tests across 10 test files covering manifest model validation, TOML parsing, discovery, visibility, cross-package refs, CLI commands, and builder manifest generation. All domain/pipe names prefixed with `pkg_test_` to avoid collisions with the existing e2e test suite. + +### Adaptations from the original brief + +1. **Model name `MthdsPackageManifest`** (not `MethodsPackageManifest`): consistent with existing `MthdsFactory`, `MthdsDecodeError` naming. + +2. **Dependencies TOML format uses alias as key**: the brief shows `[dependencies]\n"github.com/..." = { version = "^1.0.0", alias = "docproc" }` (address as key, alias inline). The implementation uses `[dependencies]\nscoring_lib = { address = "...", version = "2.0.0" }` (alias as key, address inline). This is more natural for the `->` syntax since the alias is the lookup key when resolving cross-package references. + +3. **`collect_pipe_references()` made public**: renamed from `_collect_pipe_references()` on `PipelexBundleBlueprint` because the `PackageVisibilityChecker` (an external class) needs to call it. This is a minimal API change. + +4. **`pkg_app` in `app.py` not `__init__.py`**: Ruff RUF067 prohibits logic in `__init__.py` files. Followed the existing `build/app.py` pattern: `__init__.py` is empty, `app.py` defines the Typer sub-group. + +5. **Visibility check hooked into `library_manager.py` only**: the brief suggested hooking into both `library_manager.py` and `validate_bundle.py`. The library manager hook covers the main bundle loading path, which is sufficient. `validate_bundle.py` was left unchanged to keep the change surface minimal. + +6. **Cross-package `validate_cross_package_references()` defined but not wired into runtime**: the method exists and is unit-tested, but `check_visibility_for_blueprints()` (the convenience function called by the library manager) only invokes `validate_all_pipe_references()`. This is intentional: `->` refs would already fail at the per-bundle level (the pipe wouldn't be found locally), so the cross-package checker is a preparatory API for Phase 3 when it will produce better error messages. + +7. **Dependency version supports range syntax**: `PackageDependency.version` validates against Poetry/uv-style version constraint syntax (`^1.0.0`, `~1.0.0`, `>=1.0.0, <2.0.0`, wildcards). The package's own `MthdsPackageManifest.version` remains strict semver since it represents a concrete version, not a constraint. + +--- + +## Phase 3: Cross-Package References + Local Dependency Resolution + +### Goal + +Implement the `alias->domain_path.name` syntax for cross-package references.

Summary of Changes + +| Category | Nature | Description | +|----------|--------|-------------| +| File extension | **Done** | `.mthds` (renamed from `.plx` in Phase 0) | +| Terminology | **Done** | "method" terminology throughout docs and UI (renamed from "workflow" in Phase 0) | +| Hierarchical domains | **Done** | Domains support `.`-separated hierarchy (e.g., `legal.contracts`) | +| Pipe namespacing | **Done** | Pipes gain `domain_path.pipe_code` references, symmetric with concepts | +| Package manifest | **Done** | `METHODS.toml` — identity, dependencies (parsed only), exports | +| Visibility model | **Done** | Pipes are private by default when manifest exists, exported via `[exports]` | +| CLI `pipelex pkg` | **Done** | `pipelex pkg init` (scaffold manifest), `pipelex pkg list` (display manifest) | +| Lock file | **New artifact** | `methods.lock` — resolved dependency versions and checksums | +| Dependency resolver | **New subsystem** | Fetches, caches, and version-resolves packages | +| Cross-package references | **New syntax** | `alias->domain_path.pipe_code` and `alias->domain_path.ConceptCode` | +| Bundle loading | **Major rework** | Package-aware resolver replaces flat `library_dirs` scanning | + +--- + +## 2. The Standard/Implementation Split + +The MTHDS standard defines: + +- The `.mthds` file format (TOML-based bundle definition) +- The `METHODS.toml` manifest format +- The `methods.lock` lock file format +- Namespace resolution rules (bare, domain-qualified, package-qualified with `->`) +- The package addressing scheme +- The distribution model + +Pipelex implements: + +- The runtime that loads, validates, and executes `.mthds` bundles +- The CLI (`pipelex`) that exposes standard operations +- The builder that generates `.mthds` files +- The agent CLI (`pipelex-agent`) for machine-driven building + +The standard docs should never reference Pipelex. The implementation docs reference both. + +--- + +## 3. What Changes in the File Format + +### 3.1 Extension Rename — COMPLETED (Phase 0) + +All bundle files now use the `.mthds` extension. The TOML structure inside is unchanged. + +### 3.2 Hierarchical Domains + +**Current state**: Domain names are single `snake_case` identifiers (e.g., `recruitment`, `scoring`). + +**New state**: Domains support `.`-separated hierarchies using `snake_case` segments. + +```toml +# Current (still valid) +domain = "legal" + +# New (hierarchical) +domain = "legal.contracts" +domain = "legal.contracts.shareholder" +``` + +The hierarchy is purely organizational — no implicit scope or inheritance between parent and child domains. `legal.contracts` does not automatically have access to concepts from `legal`. + +**Impact**: Domain validation must accept dotted paths. Domain storage and lookup must handle multi-segment keys. + +### 3.3 Pipe References Gain Domain Namespacing + +**Current state**: Pipes are referenced by bare `snake_case` names everywhere. + +```toml +# Current +steps = [ + { pipe = "extract_documents", result = "extracted_documents" }, + { pipe = "analyze_cv", result = "cv_analysis" }, +] +branch_pipe_code = "process_single_cv" +outcomes = { "high" = "deep_analysis", "low" = "quick_analysis" } +``` + +**New state**: Pipe references support three forms — bare (local), domain-qualified, and package-qualified. With hierarchical domains, the domain path can be multi-segment. + +```toml +# Within same bundle (unchanged) +steps = [ + { pipe = "extract_documents", result = "extracted_documents" }, +] + +# Cross-bundle, same package (single-segment domain) +steps = [ + { pipe = "scoring.compute_weighted_score", result = "score" }, +] + +# Cross-bundle, same package (hierarchical domain) +steps = [ + { pipe = "legal.contracts.extract_clause", result = "clause" }, +] + +# Cross-package +steps = [ + { pipe = "docproc->extraction.extract_text", result = "pages" }, +] +``` + +**Parsing rule**: Split on the **last `.`** to separate the domain path from the name. Casing of the last segment disambiguates: `snake_case` = pipe code, `PascalCase` = concept code. + +**All pipe reference locations affected:** + +| Field | Example | +|-------|---------| +| `steps[].pipe` (PipeSequence) | `"legal.contracts.extract_clause"` | +| `parallels[].pipe` (PipeParallel) | `"docproc->extraction.extract_text"` | +| `branch_pipe_code` (PipeBatch) | `"legal.contracts.process_nda"` | +| `outcomes` values (PipeCondition) | `"scoring.deep_analysis"` | +| `default_outcome` (PipeCondition) | `"scoring.fallback"` | + +**Not affected**: `main_pipe` (always local), pipe definition keys (`[pipe.my_pipe]` — always local). + +### 3.4 Concept References Gain Package Qualification + +**Current state**: Concepts support bare names and `domain.ConceptCode`. + +```toml +# Current — both forms already work +inputs = { profile = "CandidateProfile" } +inputs = { profile = "recruitment.CandidateProfile" } +refines = "base_domain.Person" +``` + +**New state**: Adds package-qualified form and supports hierarchical domain paths. + +```toml +# Hierarchical domain concept reference (same package) +inputs = { clause = "legal.contracts.NonCompeteClause" } + +# Cross-package concept reference +inputs = { profile = "acme_hr->recruitment.CandidateProfile" } +refines = "acme_legal->legal.contracts.NonDisclosureAgreement" +``` + +### 3.5 The Bundle Header — Domain Now Supports Hierarchy + +The top-level bundle fields remain structurally the same, but `domain` now accepts dotted paths: + +```toml +domain = "legal.contracts" +description = "Contract analysis and clause extraction" +main_pipe = "extract_clause" +``` + +No new required fields in the `.mthds` file itself. The package relationship is established by the manifest, not by the bundle. + +--- + +## 4. New Artifacts + +### 4.1 Package Manifest: `METHODS.toml` — IMPLEMENTED (Phase 2) + +Parsed and validated. Declares package identity, dependencies (stored but not resolved), and exports. + +Exports use TOML sub-tables, one per domain. The domain path maps directly to the TOML table path — `legal.contracts` becomes `[exports.legal.contracts]`. + +```toml +[package] +address = "github.com/acme/legal-tools" +version = "0.3.0" +description = "Legal document analysis and contract review methods." +mthds_version = ">=0.2.0" + +[dependencies] +docproc = { address = "github.com/mthds/document-processing", version = "1.0.0" } +scoring_lib = { address = "github.com/mthds/scoring-lib", version = "0.5.0" } + +[exports.legal] +pipes = ["classify_document"] + +[exports.legal.contracts] +pipes = ["extract_clause", "analyze_nda", "compare_contracts"] + +[exports.scoring] +pipes = ["compute_weighted_score"] +``` + +**Implementation note**: The `[dependencies]` format uses the alias as the TOML key and the address as an inline field (see §4.1 note in `mthds-implementation-brief_v6.md`). Dependency versions support Poetry/uv-style range syntax (`^1.0.0`, `~1.0.0`, `>=1.0.0, <2.0.0`, wildcards) — validated at parse time, resolution deferred to Phase 3+. The `description` field is required and must be non-empty. + +**Impact**: New parser (`manifest_parser.py`), new model class (`MthdsPackageManifest`), new validation rules, new discovery function, new visibility checker. See `pipelex/core/packages/`. + +### 4.2 Lock File: `methods.lock` + +Auto-generated by the dependency resolver. Committed to version control. + +```toml +["github.com/mthds/document-processing"] +version = "1.2.3" +hash = "sha256:a1b2c3d4..." +source = "https://github.com/mthds/document-processing" + +["github.com/mthds/scoring-lib"] +version = "0.5.1" +hash = "sha256:e5f6g7h8..." +source = "https://github.com/mthds/scoring-lib" +``` + +**Impact**: New generation/verification code, new CLI commands. + +### 4.3 Package Cache Directory + +`~/.mthds/packages/` (global) or `.mthds/packages/` (project-local). Stores fetched package contents, organized by address and version. + +--- + +## 5. Impact on Existing Pipelex Subsystems + +### 5.1 Pipe Code Validation (`pipelex/core/pipes/`) + +**Current**: `is_pipe_code_valid()` accepts only `snake_case` identifiers. + +**Change**: Must distinguish between pipe *definitions* (always bare `snake_case`) and pipe *references* (three forms: bare, `domain_path.pipe_code`, `alias->domain_path.pipe_code`). **Done in Phase 1**: implemented as the unified `QualifiedRef` model in `pipelex/core/qualified_ref.py`, handling both concept and pipe references with the "split on last dot" rule. **Extended in Phase 2**: `has_cross_package_prefix()` and `split_cross_package_ref()` static methods added for `->` syntax detection. + +### 5.2 Bundle Blueprint (`pipelex/core/bundles/`) + +**Current**: Validates pipe keys and concept references in isolation. + +**Changes**: +- `validate_pipe_keys()`: unchanged (definitions are still bare names) +- `validate_local_concept_references()`: must understand the `alias->domain_path.ConceptCode` form and skip validation for external references (already partially done for domain-qualified refs) +- `collect_pipe_references()`: **Done in Phase 2** — made public (was `_collect_pipe_references`) so the `PackageVisibilityChecker` can call it +- Both concept and pipe reference collectors need to understand the `->` syntax + +### 5.3 Interpreter (`pipelex/core/interpreter/`) + +**Current**: Loads `.mthds` files. + +**Change**: No structural change to the interpreter itself, but it needs to be called within the context of a package-aware loader that reads the manifest, resolves dependencies, and loads bundles in order. + +### 5.4 Domain Validation (`pipelex/core/domains/`) + +**Current**: Validates domain code syntax (single `snake_case` segment). + +**Change**: Must accept `.`-separated hierarchical domain paths where each segment is `snake_case`. Must also handle package-qualified domain references (`alias->domain_path`). + +### 5.5 Builder (`pipelex/builder/`) + +**Current**: Generates `.mthds` bundles. + +**Changes — Done in Phase 2**: +- `maybe_generate_manifest_for_output()` in `builder_loop.py` generates `METHODS.toml` alongside `.mthds` files when the output directory contains multiple domains +- Hooked into `pipe_cmd.py` (CLI build) and `build_core.py` (agent CLI build) + +**Still pending (Phase 3+)**: +- When building a method that depends on external packages, the builder needs awareness of available packages and their exported pipes/concepts +- Pipe signature design needs to account for cross-package pipe references + +### 5.6 CLI (`pipelex/cli/`) + +**New command group — Done in Phase 2**: `pipelex pkg` with `init` and `list` subcommands. + +| Command | Status | Does | +|---------|--------|------| +| `pipelex pkg init` | **Done** | Create a `METHODS.toml` in the current directory | +| `pipelex pkg list` | **Done** | Show package info, dependencies, and exported pipes from the manifest | +| `pipelex pkg add
` | Phase 3+ | Add a dependency to the manifest | +| `pipelex pkg install` | Phase 4 | Fetch and cache all dependencies from lock file | +| `pipelex pkg update` | Phase 4 | Update dependencies to latest compatible versions | +| `pipelex pkg lock` | Phase 4 | Regenerate the lock file | +| `pipelex pkg publish` | Phase 5 | Validate and prepare a package for distribution | + +**Existing commands impacted (Phase 3+)**: +- `pipelex validate`: must resolve packages before validating cross-package references +- `pipelex run`: must load dependency packages into the runtime +- `pipelex-agent build`: should be package-aware for cross-package pipe references + +### 5.7 Pipe Blueprints (All Pipe Types) + +Every pipe type that holds references to other pipes needs its validation/resolution updated: + +| Pipe Type | Fields Holding Pipe References | +|-----------|-------------------------------| +| `PipeSequenceBlueprint` | `steps[].pipe` | +| `PipeParallelBlueprint` | `parallels[].pipe` | +| `PipeBatchBlueprint` | `branch_pipe_code` | +| `PipeConditionBlueprint` | `outcomes` values, `default_outcome` | + +Each of these must accept and parse the three-scope pipe reference format. Look in `pipelex/pipe_controllers/`. + +### 5.8 Library Manager (`pipelex/libraries/`) — NEW (Phase 2) + +**Change**: `_check_package_visibility()` added to `library_manager.py`. After parsing all blueprints from `.mthds` files, it: +1. Finds the nearest `METHODS.toml` manifest via walk-up discovery +2. If found, runs the `PackageVisibilityChecker` against all blueprints +3. Raises `LibraryLoadingError` if cross-domain pipe references violate visibility + +--- + +## 6. Implementation Roadmap + +Each phase gets its own implementation brief with decisions, grammar, acceptance criteria, and codebase pointers. See the latest `mthds-implementation-brief_v*.md` for the current phases. + +| Phase | Goal | Depends on | +|-------|------|-----------| +| **0** | ~~Extension rename + terminology update~~ | **COMPLETED** | +| **1** | ~~Hierarchical domains + pipe namespacing: `domain_path.pipe_code` references, split-on-last-dot parsing for concepts and pipes~~ | **COMPLETED** | +| **2** | ~~Package manifest (`METHODS.toml`) + exports / visibility model~~ | **COMPLETED** | +| **3** | Cross-package references (`alias->domain_path.name`) + local dependency resolution | Phase 2 | +| **4** | Remote dependency resolution, lock file (`methods.lock`), package cache | Phase 3 | +| **5** | Registry, type-aware search, Know-How Graph browsing | Phase 4 | + +--- + +## 7. Migration Guide for Existing Bundles + +### What Stays the Same + +- Bundle file format is still TOML +- `domain`, `description`, `main_pipe` fields unchanged +- `[concept]` and `[pipe]` sections unchanged +- Bare pipe references (`"extract_documents"`) still work within a bundle +- Concept `domain.ConceptCode` references unchanged +- Native concepts (`Text`, `Image`, etc.) unchanged + +### What Changes + +- ~~File extension is now `.mthds`~~ (done in Phase 0) +- ~~Terminology is now "method"~~ (done in Phase 0) +- Domains can now be hierarchical: `legal.contracts.shareholder` (optional, for organization) +- Pipe references can now be `domain_path.pipe_code` (optional, for cross-bundle clarity) +- Packages with a `METHODS.toml` get dependency management and export controls +- Cross-package references use `alias->domain_path.name` syntax + +### Migration Steps for an Existing Project + +1. **To adopt packages**: run `pipelex pkg init` in your project directory. This creates a `METHODS.toml` with your bundles auto-discovered. +2. **To use cross-bundle pipes**: change bare pipe references to `domain_path.pipe_code` where you reference pipes from a different bundle in the same project. +3. **To depend on external packages**: add `[dependencies]` to your `METHODS.toml`, use `alias->domain_path.name` in your `.mthds` files. + +### Breaking Changes + +| Change | Impact | Migration | +|--------|--------|-----------| +| `.mthds` extension | Done (Phase 0) | — | +| Pipe reference parser accepts `.` and `->` | Low — new syntax, old syntax still works | None needed | +| `main_pipe` auto-exported | Low — only affects packages with manifest | Intentional; remove from `[exports]` if you want to override | +| Pipes private by default with manifest | Medium — only affects packages with `METHODS.toml` | Run `pipelex pkg init` to auto-export all pipes, then trim | + +--- + +*This document tracks the delta between current Pipelex and the MTHDS standard implementation.

Vision + +Methods are designed to be composable, shareable, and reusable. Today, bundles can reference concepts across domains, but the standard lacks the infrastructure for web-scale distribution: there are no globally unique addresses, no explicit dependencies, no visibility controls, and pipes lack the namespacing that concepts already have. + +The MTHDS Package System introduces the structures needed to turn individual bundles into nodes of the **Know-How Graph**: a federated network of reusable, discoverable, type-safe AI methods. + +### Design Principles + +These principles are drawn from what works in existing ecosystems (Go modules, Rust crates, Agent Skills) and what's unique to MTHDS: + +- **Filesystem as interface.** Packages are directories of text files. Git-native, human-readable, agent-readable. No proprietary formats, no binary blobs. +- **Progressive enhancement.** A single `.mthds` file still works. Packaging is opt-in complexity added only when you need distribution. +- **Type-driven composability.** Unlike Agent Skills (discovered by text description), pipes have typed signatures. The concept system enables semantic discovery: "I have X, I need Y." +- **Federated distribution.** Decentralized storage (Git), centralized discovery (registries). No single point of ownership. +- **Packages own namespaces, domains carry meaning.** The package is the ownership/isolation boundary. The domain is a semantic label and an intra-package namespace, but it never merges across packages. + +--- + +## 2. Core Concepts + +### Three Layers + +| Layer | What it is | Role | +|-------|-----------|------| +| **Domain** | A semantic namespace for concepts and pipes within a package. E.g., `recruitment`, `legal.contracts`, `scoring`. | Intra-package organization. Semantic label for discovery. Carries meaning about what the bundle is about. | +| **Bundle** | A single `.mthds` file. Declares exactly one domain. Contains concept definitions and pipe definitions. | The authoring unit. Where concepts and pipes are defined. | +| **Package** | A directory with a manifest (`METHODS.toml`) and one or more bundles. Has a globally unique address. | The distribution unit. Owns a namespace. Declares dependencies and exports. | + +### Hierarchical Domains + +Domains can be hierarchical, using `.` as the hierarchy separator: + +``` +legal +legal.contracts +legal.contracts.shareholder_agreements +``` + +This enables natural organization of complex knowledge areas. A large package covering legal methods can structure its domains as a tree rather than a flat list. + +**The hierarchy is purely organizational.** There is no implicit scope or inheritance between parent and child domains. `legal.contracts` does not automatically have access to concepts defined in `legal`. If a bundle in `legal.contracts` needs concepts from `legal`, it uses explicit domain-qualified references — the same as any other cross-domain reference. This keeps the system predictable: you can read a bundle and know exactly where its references come from. + +### Key Rule: Packages Isolate Namespaces + +Two packages can both declare `domain = "recruitment"`. Their concepts and pipes are completely independent — there is no merging. The domain name is semantic (it tells you what the bundle is about) and serves as a namespace within its package, but across packages, the package address is the true isolation boundary. + +This means: + +- `recruitment.CandidateProfile` from Package A and `recruitment.CandidateProfile` from Package B are **different things**. +- To reference something from another package, you must qualify it with the package identity. +- Within a single package, bundles sharing the same domain DO merge their namespace (same behavior as today's multi-file loading). Conflicts within the same package + same domain are errors. + +### Why Not Merge Domains? + +Merging domains across packages would create fragile implicit coupling: any package declaring `domain = "recruitment"` could inject concepts into your namespace. Instead, cross-package composition is explicit — through dependencies, concept refinement, and pipe invocation. This is how Go modules, Rust crates, and every robust package system works: you build on top of other packages, you don't extend their namespace. + +The domain remains valuable for **discovery**: searching the Know-How Graph for "all packages in the recruitment domain" is powerful. But discovery is not namespace merging. + +### Domain Naming Rules + +- Domain names must be lowercase `snake_case` segments, optionally separated by `.` for hierarchy. +- Each segment follows `snake_case` rules: `[a-z][a-z0-9_]*`. +- Recommended depth: 1-3 levels. Recommended segment length: 1-4 words. +- Reserved domains that cannot be used by packages: `native`, `mthds`, `pipelex`. (Note: currently not enforced by domain validation — the manifest parser is the right place to check this.) + +--- + +## 3. Package Structure + +A package is a directory following progressive enhancement — start minimal, add structure as needed: + +``` +legal-tools/ +├── METHODS.toml # Package manifest (required for distribution) +├── general_legal.mthds # Bundle: domain = "legal" +├── contract_analysis.mthds # Bundle: domain = "legal.contracts" +├── shareholder_agreements.mthds # Bundle: domain = "legal.contracts.shareholder" +├── scoring.mthds # Bundle: domain = "scoring" +├── README.md # Optional: human-facing documentation +├── test_data/ # Optional: example inputs +│ └── inputs.json +└── LICENSE # Optional: licensing terms +``` + +### Minimal Package + +The absolute minimum for a distributable package: + +``` +my-tool/ +├── METHODS.toml +└── method.mthds +``` + +### Standalone Bundle (No Package) + +A `.mthds` file without a manifest still works. It behaves as an implicit local package with no dependencies (beyond native concepts) and all pipes public. This preserves the "single file = working method" experience for learning, prototyping, and simple projects. + +--- + +## 4. The Package Manifest + +`METHODS.toml` — the identity card and dependency declaration for a package. + +```toml +[package] +address = "github.com/acme/legal-tools" +version = "0.3.0" +description = "Legal document analysis and contract review methods." +authors = ["ACME Legal Tech "] +license = "MIT" +mthds_version = ">=0.2.0" + +[dependencies] +"github.com/mthds/document-processing" = { version = "^1.0.0", alias = "docproc" } +"github.com/mthds/scoring-lib" = { version = "^0.5.0", alias = "scoring_lib" } + +[exports.legal] +pipes = ["classify_document"] + +[exports.legal.contracts] +pipes = ["extract_clause", "analyze_nda", "compare_contracts"] + +[exports.scoring] +pipes = ["compute_weighted_score"] +``` + +### Fields + +**`[package]`** + +| Field | Required | Description | +|-------|----------|-------------| +| `address` | Yes | Globally unique identifier. Must start with a hostname. URL-style, self-describing. The address IS the fetch location (modulo protocol). | +| `version` | Yes | Semantic version. | +| `description` | Yes | Human-readable summary of the package's purpose. Written at the package level (not duplicating pipe signatures). | +| `authors` | No | List of author identifiers. | +| `license` | No | SPDX license identifier. | +| `mthds_version` | No | Minimum MTHDS standard version required. | + +**`[dependencies]`** + +Each key is a package address (must start with a hostname). Values: + +| Field | Required | Description | +|-------|----------|-------------| +| `version` | Yes | Version constraint (semver range). | +| `alias` | Yes | Short `snake_case` name for use in `.mthds` cross-package references. Must be valid `snake_case`. No auto-defaulting — explicit aliases keep references readable and intentional. | + +**`[exports]`** + +Uses TOML sub-tables, one per domain. The domain path maps directly to the TOML table path — `legal.contracts` becomes `[exports.legal.contracts]`. Each sub-table contains: + +| Field | Required | Description | +|-------|----------|-------------| +| `pipes` | Yes | List of pipe codes that are public from this domain. | + +Rules: + +- **Concepts are always public.** They are vocabulary — the whole point of domains is shared meaning. +- **Pipes are private by default.** A non-exported pipe is only accessible from within its own domain. Pipes listed in `[exports]` are callable from any domain within the package and by external packages. +- **`main_pipe` is auto-exported.** If a bundle declares a `main_pipe`, it is automatically part of the public API. +- Pipes not listed in exports are implementation details — invisible to consumers. + +--- + +## 5. Namespace Resolution + +References to concepts and pipes resolve through three scopes, from most local to most global. + +### Parsing Rule + +A reference is parsed by splitting on the **last `.`** to separate the domain path from the name: + +- `extract_clause` → bare name (no dot, local) +- `legal.contracts.extract_clause` → domain `legal.contracts`, pipe `extract_clause` +- `legal.contracts.NonCompeteClause` → domain `legal.contracts`, concept `NonCompeteClause` +- `scoring.compute_score` → domain `scoring`, pipe `compute_score` + +The casing of the last segment disambiguates: `snake_case` = pipe code, `PascalCase` = concept code. This is unambiguous because pipe codes and concept codes follow different casing conventions. + +For package-qualified references, `->` is split first: + +- `docproc->legal.contracts.extract_clause` → package `docproc`, domain `legal.contracts`, pipe `extract_clause` + +### Scope 1: Bundle-Local (Bare Names) + +Within a `.mthds` file, bare names resolve to the current bundle and its domain. This is how things work today. + +```toml +# In contract_analysis.mthds (domain = "legal.contracts") +[pipe.extract_clause] +inputs = { contract = "ContractDocument" } # concept from this bundle +output = "NonCompeteClause" # concept from this bundle +steps = [ + { pipe = "parse_sections", result = "sections" } # pipe from this bundle +] +``` + +### Scope 2: Domain-Qualified (Cross-Bundle, Same Package) + +When referencing something from another bundle within the same package (or for explicitness), use `domain_path.name`: + +```toml +# Concepts — single-segment domain (already supported today) +inputs = { doc = "legal.ClassifiedDocument" } +output = "scoring.WeightedScore" + +# Concepts — hierarchical domain (NEW) +inputs = { clause = "legal.contracts.NonCompeteClause" } + +# Pipes (NEW — same syntax as concepts) +steps = [ + { pipe = "legal.classify_document", result = "classified" }, + { pipe = "legal.contracts.extract_clause", result = "clause" }, + { pipe = "scoring.compute_weighted_score", result = "score" } +] +``` + +This is the main change for pipe namespacing: pipes get domain-qualified references, symmetric with concepts. + +### Scope 3: Package-Qualified (Cross-Package) + +When referencing something from another package, prefix with the package alias and `->`: + +```toml +# Using dependency alias from METHODS.toml +inputs = { pages = "docproc->extraction.Page" } +steps = [ + { pipe = "docproc->extraction.extract_text", result = "pages" } +] +``` + +The `->` (arrow) separator was chosen for **readability by non-technical audiences**. MTHDS is a language that business people and domain experts read and contribute to — the separator must feel natural, not "geeky." + +- Reads as natural language: "from docproc, get extraction.extract_text" +- Directional — conveys "reaching into another package" intuitively +- Visually distinctive from `.` — the package boundary is immediately visible at a glance +- Universally understood (arrows are not a programming concept) + +**Alias naming rule**: Package aliases must be `snake_case` (consistent with domain names). This ensures clean readability — e.g., `acme_hr->recruitment.extract_cv`. + +### Resolution Order + +When resolving a bare reference like `NonCompeteClause`: + +1. Check native concepts (`Text`, `Image`, `Document`, etc.) — native always takes priority +2. Look in the current bundle's declared concepts +3. Look in other bundles of the same domain within the same package +4. If not found: error + +When resolving `legal.contracts.NonCompeteClause`: + +1. Look in the `legal.contracts` domain within the current package +2. If not found: error (domain-qualified refs don't fall through to dependencies) + +When resolving `acme->legal.contracts.NonCompeteClause`: + +1. Look in the `legal.contracts` domain of the package aliased as `acme` +2. If not found: error + +### Special Namespace: `native` + +Built-in concepts remain accessible as `native.Image`, `native.Text`, etc. — or by bare name (`Image`, `Text`) since they're always in scope. The `native` prefix is a reserved namespace that no package can claim. + +--- + +## 6. Pipe Namespacing — All Reference Points + +Every place in the `.mthds` format that references a pipe must support the three-scope syntax: + +| Location | Current | With Namespacing | +|----------|---------|-----------------| +| `main_pipe` | `"extract_clause"` | `"extract_clause"` (always local) | +| `steps[].pipe` | `"extract_documents"` | `"extract_documents"` or `"legal.contracts.extract_clause"` or `"pkg->legal.contracts.extract_clause"` | +| `parallels[].pipe` | `"analyze_cv"` | Same three-scope options | +| `branch_pipe_code` | `"process_single_cv"` | Same three-scope options | +| `outcomes` values | `"deep_analysis"` | Same three-scope options | +| `default_outcome` | `"fallback_analysis"` | Same three-scope options | + +**Rule**: Pipe *definitions* (the `[pipe.my_pipe]` keys) are always local bare names.

Two directories on disk, each with its own `METHODS.toml`, the consumer declaring the provider as a local path dependency. This tests the full resolution pipeline — discover manifest, read exports, validate visibility — with zero network I/O. + +### 2.1 Fixture layout + +The test fixtures live under `tests/data/packages/` and follow this structure: + +``` +tests/data/packages/ +├── provider_package/ +│ ├── METHODS.toml # declares [exports.scoring] +│ └── scoring/ +│ └── scoring.mthds # defines compute_weighted_score (public) + internal_score_normalizer (private) +│ +├── consumer_valid/ +│ ├── METHODS.toml # [dependencies] scoring_lib = { path = "../provider_package" } +│ └── analysis/ +│ └── analysis.mthds # uses scoring_lib->scoring.compute_weighted_score (valid) +│ +├── consumer_invalid/ +│ ├── METHODS.toml # same dependency declaration +│ └── analysis/ +│ └── analysis.mthds # uses scoring_lib->scoring.internal_score_normalizer (blocked — not exported) +│ +└── consumer_unknown_alias/ + ├── METHODS.toml # no [dependencies] section + └── analysis/ + └── analysis.mthds # uses nonexistent_lib->scoring.compute_weighted_score (unknown alias) +``` + +### 2.2 What the local path dependency looks like + +The consumer's `METHODS.toml` uses a `path` field instead of (or alongside) an `address`: + +```toml +[package] +name = "contract-analysis" +version = "1.0.0" +description = "Analyzes contracts using external scoring" + +[dependencies] +scoring_lib = { path = "../provider_package", version = "^1.0.0" } +``` + +The `path` field is resolved relative to the `METHODS.toml` file's location. This is the same pattern used by Cargo (`path = "..."`), Go (`replace` directive), and Poetry (`path` dependencies). + +### 2.3 Test cases + +These are automated tests (pytest), not manual steps: + +| Test case | Consumer fixture | Expected result | +|-----------|-----------------|-----------------| +| Valid cross-package ref | `consumer_valid/` | Passes — pipe is exported by provider | +| Private pipe ref | `consumer_invalid/` | Fails — `internal_score_normalizer` not in provider's `[exports]` | +| Unknown alias | `consumer_unknown_alias/` | Fails — alias not declared in `[dependencies]` | +| Provider has no manifest | (provider without METHODS.toml) | Passes — no manifest means all public | +| Provider `main_pipe` auto-export | (consumer refs provider's main_pipe not in exports) | Passes — main_pipe is auto-exported | + +### 2.4 Running the tests + +```bash +make tp TEST=TestCrossPackageLocalPath +``` + +### 2.5 Why this layer matters + +Local path dependencies test the **exact same resolution logic** that remote dependencies will use — the only difference is *how* the provider package is located on disk. Once the provider's directory is found: + +1. Read its `METHODS.toml` +2. Build a `PackageVisibilityChecker` from its exports +3. Validate the consumer's `->` references against the provider's exports + +Steps 1-3 are identical regardless of whether the provider came from a local path, a local git clone, or a GitHub fetch. This is why local path tests give high confidence. + +--- + +## Layer 3: Integration Tests with Local Git Repos + +This layer tests the VCS fetch path — cloning a repo, checking out a version, reading its manifest — without touching the network. It uses bare git repos on the local filesystem with `file://` protocol URLs. + +### 3.1 How it works + +The test setup creates temporary git repos using `git init --bare`, pushes fixture content to them, and tags releases. The consumer's dependency uses a `file://` URL instead of a `github.com/...` address: + +```toml +[dependencies] +scoring_lib = { address = "file:///tmp/test-repos/scoring-methods.git", version = "^1.0.0" } +``` + +### 3.2 Test setup (pytest fixture) + +A pytest fixture handles the lifecycle: + +1. Create a temp directory +2. Initialize a bare git repo: `git init --bare /tmp/test-repos/scoring-methods.git` +3. Clone it to a working copy, add the provider package files (METHODS.toml + .mthds bundles) +4. Commit and tag: `git tag v1.0.0` +5. Push to the bare repo +6. Yield the `file://` URL to the test +7. Clean up on teardown + +This mirrors exactly what happens with a real GitHub repo, but runs entirely on the local filesystem. + +### 3.3 Test cases + +| Test case | Setup | Expected result | +|-----------|-------|-----------------| +| Clone + resolve valid ref | Provider tagged `v1.0.0`, consumer requires `^1.0.0` | Passes — version matches, pipe is exported | +| Version mismatch | Provider tagged `v1.0.0`, consumer requires `^2.0.0` | Fails — no matching version | +| Clone + visibility violation | Provider exports only `compute_weighted_score`, consumer refs private pipe | Fails — visibility error with helpful message | +| Multiple tags | Provider has `v1.0.0` and `v1.1.0`, consumer requires `^1.0.0` | Resolves to `v1.1.0` (latest matching) | + +### 3.4 Running the tests + +```bash +make tp TEST=TestCrossPackageGitLocal +``` + +### 3.5 What this adds over Layer 2 + +Layer 2 tests the resolution logic assuming the provider is already on disk. Layer 3 tests the **fetch** logic: + +- Can we clone from a URL? +- Can we resolve version constraints against git tags? +- Can we read the manifest from the cloned repo? +- Does caching work (second resolve doesn't re-clone)? + +These are the moving parts that break when the VCS integration has bugs. + +--- -## A. Local Testing (single repo, visibility enforcement) +## Layer 4: Manual Smoke Test (GitHub) + +This is a one-time manual test to confirm end-to-end behavior with real GitHub repos.
