Tests cover success cases (multi-field, single-field, auto-generated

executable methods in docstrings, error messages, and project docs.
Generic programming usage of "workflow" is left unchanged.

…lization

Introduces a new EdgeKind.PARALLEL_COMBINE to show how individual branch
outputs are merged into the combined result in PipeParallel, analogous to
BATCH_AGGREGATE for PipeBatch. The edges render as purple dashed lines in
ReactFlow and Mermaid views. The graph tracer snapshots original branch
producers before register_controller_output overrides the producer map,
ensuring correct edge source resolution during teardown.

…branch variant

Wrap the combined_output test in a PipeSequence with a follow-up PipeLLM
that consumes the combined result, making the graph more realistic. Add a
new 3-branch PipeParallel test with selective downstream consumption where
2 branches are consumed and 1 is unused. Parametrize the test to cover both
variants.

Introduce QualifiedRef as the centralized model for domain-qualified
reference parsing, replacing scattered .split(".")/rsplit(".") calls
across 8+ files. This enables hierarchical domains (e.g. "legal.contracts")
and domain-qualified pipe references (e.g. "scoring.compute_score"),
making pipes symmetric with the existing concept reference system.

Batch/parallel edges were referencing controller node IDs, but controllers
are rendered as Mermaid subgraphs (not nodes), creating phantom auto-generated
nodes. Fix by using source_stuff_digest/target_stuff_digest to connect
stuff-to-stuff instead, rendering missing stuff nodes on the fly. Also place
parallel_combine target stuffs inside their controller's subgraph and use
plain dashed arrows (-.->)  when edge labels are empty to avoid Mermaid
syntax errors.

…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.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…ackage 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.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

New pages: packages.md (manifest reference, exports/visibility, dependencies,
directory structure, quick start) and pkg.md (CLI reference for pkg init/list).
Updated domain.md with hierarchical domains section, project-organization.md
with METHODS.toml in project tree, CLI index with pkg command row, and
mkdocs.yml nav entries.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…date_all

Add a step-by-step manual testing guide (refactoring/testing-package-system.md)
with ready-to-use .mthds fixture files covering local visibility enforcement
and cross-package reference syntax. Mark test_validate_all as xfail since the
test fixtures contain intentional visibility violations for testing purposes.

… file discovery order)

On Linux/GHA, file discovery order differs from macOS: the visibility check
may not find the fixture METHODS.toml, causing a DomainLibraryError from
duplicate 'scoring' domain instead of the LibraryLoadingError seen locally.

Non-table dependency values (e.g. `foo = "1.0.0"`) were silently dropped
during parsing, causing confusing errors later during alias resolution.
Now raises ManifestValidationError immediately with a clear message.

The export-building loop in do_pkg_init was using sorted(pipe_codes)
and ignoring the populated domain_main_pipes dict, making it dead code.
Now matches the sibling pattern in builder_loop.py by placing main_pipe
first in each domain's export list before appending remaining pipes.

Deduplicate ~35 lines of identical .mthds scanning and DomainExports
building logic from builder_loop.py and init_cmd.py into two shared
functions in pipelex/core/packages/bundle_scanner.py, reducing
divergence risk when fixing or extending this code path.

…INE unit test

The controller_combine_digests set was populated but never read anywhere in the
codebase. The controller_output_stuffs dict already tracks the same digests and
is the structure actually used for rendering. Added a unit test covering the
PARALLEL_COMBINE subgraph rendering path to guard against future regressions.

Make `format` and `lint` composite targets that include both ruff and plxt,
replacing the previous flat structure where plxt targets were bolted on
separately. Adds dedicated `ruff-format` and `ruff-lint` targets, re-enables
plxt-format/plxt-lint (previously no-op), and simplifies `c` and `agent-check`.

Also fixes awkward `method.mthds` filename to `main.mthds` in the minimal

Final document in the 6-part MTHDS documentation series. Covers building

Feature/epic mths docs

Rename docs-deploy-404 to docs-deploy-root and extend it to deploy three
root assets instead of one: robots.txt (blocks crawlers from indexing
duplicate versioned paths), index.html (meta-refresh redirect to /latest/
with canonical link), and the existing 404.html.

Reverse deploy ordering so mike runs first (ensuring gh-pages exists),
then root assets are layered on top. Add git fetch for CI compatibility
where the local gh-pages ref may not exist.

mthds-12 Phases 6-7: domain enforcement, version validation, type search, and composition

Close validation gaps in manifest models: reject empty/whitespace author
strings and license values, detect unknown keys in [package] TOML section,
and add tests for extra="forbid" enforcement and description whitespace
variants.

Introduce a cosmetic display_name field in [package] for human-friendly
labels in CLI output and registry listings. The field is validated
(non-empty when provided, max 128 chars, no control characters, strips
whitespace, emojis allowed) and never used as an identifier — address
remains the sole canonical key.

Add optional display_name field to MTHDS package manifest

PipeLibrary.get_optional_pipe now verifies the domain path matches the
pipe's actual domain_code, returning None on mismatch instead of silently
ignoring the qualifier. QualifiedRefError is caught gracefully so that
malformed refs return None rather than raising.
