 avoid repeated full scans for basic discovery.
 The same registry is exposed on the CLI for practical discovery:
 ```bash
 mkt extension list
 mkt extension inspect memory.context-package
 mkt extension commands
 ```
 This makes the extension catalog part of the user-visible contract. When a
 capability gains a CLI command, the descriptor should declare that command so
 generated docs and audits can compare intent with the live surface.

 `ExtensionExecutor` wraps a descriptor factory with deterministic lifecycle

 # Practical Usecase Relevance
 This document translates the project intent, PRD, FRS, and current
 implementation into practical adoption usecases for `markitect-tool`.
 The relevance expectations are based on the local product scope plus a light web
 research pass across Markdown documentation ecosystems, docs-as-code practice,
 RAG/agent context tooling, policy-as-code systems, and Markdown publishing
 systems.
 ## Research Signals
 - CommonMark exists because Markdown needed a strongly defined, compatible
  specification across many implementations: https://commonmark.org/
 - GitLab documents large handbook and product-doc workflows in Markdown, with
  linting/style enforcement in the pipeline:
  https://handbook.gitlab.com/docs/markdown-guide/ and
  https://docs.gitlab.com/development/documentation/styleguide/
 - MkDocs positions itself directly as project documentation with Markdown and
  uses Markdown files plus YAML configuration:
  https://www.mkdocs.org/
 - Docusaurus uses Markdown/MDX as its main authoring format and highlights the
  tension between CommonMark compatibility and richer MDX component behavior:
  https://docusaurus.io/docs/3.2.1/markdown-features
 - LangChain and Semantic Kernel both model RAG around loading, splitting,
  storing, retrieving, and injecting text context:
  https://docs.langchain.com/oss/python/langchain/rag and
  https://learn.microsoft.com/en-us/semantic-kernel/frameworks/agent/agent-rag
 - OPA and OpenFGA show that policy and authorization are commonly externalized
  into dedicated engines, which supports Markitect's adapter-first boundary:
  https://www.openpolicyagent.org/docs and https://openfga.dev/docs/fga
 - Quarkdown demonstrates current interest in Markdown extended with functions,
  scripting, and richer publishing semantics:
  https://www.quarkdown.net/about
 - Click already supports shell completion for Bash, Zsh, and Fish when exposed
  through an installed entry point:
  https://click.palletsprojects.com/en/stable/shell-completion/
 - pdoc and Sphinx show common expectations for automatic Python API
  documentation from public APIs and docstrings:
  https://pdoc.dev/ and
  https://www.sphinx-doc.org/en/master/usage/extensions/apidoc.html
 ## Usecase Matrix
 | Usecase | Relevance | Why It Matters | Current Support | E2E Variations |
 | --- | --- | --- | --- | --- |
 | Parse Markdown into structured ASTs | Foundational | Every higher-level workflow needs stable structure and source spans. | `mkt parse`, `mkt ast`, API parser primitives | Small single note, typical ADR/PRD, large multi-section document |
 | Contract-check business documents | High | Teams need predictable structure, assertions, field validation, and diagnostics. | `mkt contract validate/check/form-state`, contract APIs | Small concept note, typical ADR/business letter, large PRD/FRS bundle |
 | Query and extract reusable content | High | Docs-as-code and agent/RAG workflows need selectors over source Markdown. | `mkt query`, `mkt extract`, JSONPath, indexed query | Small file query, typical docs directory, large cached corpus |
 | Transform, compose, include, transclude | High | Real document pipelines need deterministic reuse without manual copy/paste. | `mkt transform`, `compose`, `include`, references, processors | Small include, typical multi-source review, large composed handbook segment |
 | Generate documents from templates/contracts | High | Practical adoption depends on producing useful Markdown, not only checking it. | `mkt template`, `mkt generate`, document functions | Small template, typical release notes, large generated document pack |
 | Declarative Markdown workflows | High | Business usecases need repeatable pipelines with intent, inputs, outputs, and diagnostics. | `mkt workflow inspect/plan/run` | Small source-snippet workflow, typical ADR release notes, large multi-input pipeline |
 | Local indexing, search, and incremental refresh | High | Large corpora require speed, change detection, and retrieval without reparsing everything. | `mkt cache`, `mkt backend refresh-plan`, `mkt search` | Small two-file index, typical docs tree, large synthetic corpus |
 | Policy-aware knowledge access | Medium-high | Enterprise use needs safe filtering and explainable denial without making Markitect the IAM system. | `mkt policy`, policy-filtered `search`, policy-filtered `cache query` | Public/private notes, typical trust-zone docs, large labelled corpus |
 | Literate weave/tangle workflows | Medium-high | Knuth-style authoring and modern docs-as-code both benefit from code/document roundtrips. | `mkt tangle`, `mkt weave` | Small code chunk, typical app skeleton, large multi-file tangle |
 | Explode/implode document sections | Medium-high | Human editing and review often need splitting documents while preserving roundtrip integrity. | `mkt explode`, `mkt implode` | Small flat split, typical hierarchical doc, large section tree |
 | Runtime forms and dynamic context prefill | Medium-high | Structured documents often originate as form-like workflows with validation and prefills. | `mkt contract form-state`, runtime context APIs | Small static form, typical prefilled letter, large dynamic contract |
 | Agent working-memory context packages | Medium-high | Agents need bounded, inspectable context payloads with provenance and policy rechecks. | `mkt context pack/activate/explain/refresh/list` | Small source package, typical indexed package, large budget-limited package |
 | Document function layer | Medium | Quarkdown-like function layers make Markdown more expressive while keeping deterministic boundaries. | `mkt function list/check/render` | Small inline function, typical function fence, large generated function document |
 | Internal extension framework | Medium | Future growth requires extension isolation, descriptors, docs, safety, and CLI/API visibility. | `mkt extension list/inspect/commands`, extension APIs | Built-in registry, docs descriptor, future optional adapter descriptor |
 | Generated CLI/API documentation | Medium | Accessibility improves when users can discover the live surface without reading code. | `mkt docs cli`, `mkt docs api`, generated docs files | Console output, committed Markdown, packaging docs build |
 ## Coverage Expectations
 The adoption polish work should treat these usecases as the public contract:
 - Each usecase should have at least one API test and one CLI test.
 - Each high-relevance usecase should have small, typical, and large E2E
  fixtures.
 - Large fixtures should be synthetic enough to stay fast but big enough to catch
  obvious performance regressions.
 - E2E tests should assert useful behavior, diagnostics, and output shape, not
  only zero exit codes.
 - Optional adapters should be tested through stable local fakes and must not
  require network or live LLM calls.
 ## Accessibility Expectations
 Markitect becomes more accessible when:
 - users can install one command and get `--help`, tab completion, and generated
  command docs
 - every architecture capability is discoverable through `mkt extension`
 - API docs are generated from the public API and kept close to the source
 - examples map directly to usecases and can be copied into local experiments
 - diagnostics use stable codes, source locations, and concise remediation hints
 - defaults support practical single-file work before asking users to configure a
  full project

 # MKTT-WP-0017: CLI/API Polish And Practical Adoption
 ## Purpose
 Polish `markitect-tool` from a broad implementation toolkit into something that
 is easy to discover, use, document, test, and adopt in practical Markdown
 pipelines.
 This workplan intentionally pauses advanced future architecture work and focuses
 on the public surface:
 - CLI completeness and consistency
 - shell completion and Unix-style generated command documentation
 - public API completeness and generated API documentation
 - CLI/API alignment with the extension architecture
 - usecase-driven E2E testing
 - accessibility for practical first use
 ## Decisions
 - Treat every implemented architecture capability as something that should be
  discoverable through CLI, API, docs, and extension descriptors.
 - Keep generated docs deterministic and local-first.
 - Use web-researched practical usecases as adoption and E2E-test anchors.
 - Prefer improving command/API discoverability before adding more advanced
  features.
 ## P17.1 - Audit CLI and API surface completeness
 ```task
 id: MKTT-WP-0017-T001
 status: done
 priority: high
 state_hub_task_id: "1827fec2-3c64-4dd0-9b24-e6a7c3a19912"
 ```
 Review all implemented modules, built-in extensions, and docs. Identify missing
 CLI accesspoints, missing public API exports, and mismatches between extension
 descriptors and real commands.
 Initial implementation adds:
 - `mkt completion`
 - `mkt extension list`
 - `mkt extension inspect`
 - `mkt extension commands`
 - `mkt docs cli`
 - `mkt docs api`
 - top-level API exports for newer query, backend, extension, schema, and policy
  surfaces
 Output: implementation, tests, and an updated audit note if gaps remain.
 ## P17.2 - Provide shell completion and Unix-style command docs
 ```task
 id: MKTT-WP-0017-T002
 status: done
 priority: high
 state_hub_task_id: "052b9684-cc23-4215-926e-bc498fe10f4f"
 ```
 Expose Bash, Zsh, and Fish completion scripts through the CLI and generate a
 Markdown command reference from the live Click tree.
 Output: CLI command, generated `docs/cli-reference.md`, README installation
 notes, and tests.
 ## P17.3 - Provide generated API documentation
 ```task
 id: MKTT-WP-0017-T003
 status: done
 priority: high
 state_hub_task_id: "8874078a-e2f4-4a4e-a2d0-a7cbd5d62816"
 ```
 Generate a compact public API reference from `markitect_tool.__all__` and make
 `pdoc` available as an optional richer documentation path.
 Output: CLI command, generated `docs/api-reference.md`, optional docs extra,
 README notes, and tests.
 ## P17.4 - Compile practical usecases and relevance expectations
 ```task
 id: MKTT-WP-0017-T004
 status: done
 priority: high
 state_hub_task_id: "23fffff4-a1f0-498c-b4d7-00241d0bb29d"
 ```
 Revisit `INTENT.md`, PRD, FRS, examples, and docs. Use web research to define a
 practical usecase matrix with relevance expectations and adoption signals.
 Output: `docs/practical-usecase-relevance.md` and links from intent/README.
 ## P17.5 - Build E2E fixture matrix
 ```task
 id: MKTT-WP-0017-T005
 status: in_progress
 priority: high
 state_hub_task_id: "1159ec82-00e6-45cd-8a2c-e61ae03e758a"
 ```
 Create E2E tests for the practical usecases with small, typical, and large
 variations where meaningful.
 Required coverage:
 - parse/AST/metrics
 - schema and contract checks
 - query/extract and indexed search
 - transform/compose/include/references/processors
 - templates/generation/functions
 - workflow inspect/plan/run
 - cache/index/refresh plans
 - policy-aware query/search
 - literate weave/tangle
 - explode/implode
 - runtime form-state
 - context packages
 - extension catalog and generated docs
 Output: deterministic tests and fixtures with no network dependency.
 Initial coverage has been added for:
 - small, typical, and large synthetic corpus parse/query/cache/search/context
  package flow
 - example-backed contract, template, function, workflow, reference, processor,
  policy, literate tangle, and explode/implode flows
 Remaining work: expand the matrix into explicit small/typical/large variants
 for every high-relevance workflow and add performance assertions where they are
 stable.
 ## P17.6 - Run coverage and performance iteration
 ```task
 id: MKTT-WP-0017-T006
 status: todo
 priority: high
 state_hub_task_id: "8dd5afe5-cefa-4388-bf4c-a975ba5c77c3"
 ```
 Run full tests repeatedly, add coverage instrumentation if needed, and fix bugs
 or performance issues exposed by the E2E matrix.
 Output: passing test suite, documented coverage gaps, and targeted performance
 notes for large synthetic corpora.
 ## P17.7 - Improve first-use accessibility
 ```task
 id: MKTT-WP-0017-T007
 status: todo
 priority: medium
 state_hub_task_id: "590af805-0cc0-4585-b85f-9e95679afa77"
 ```
 Make the first useful experience obvious.
 Possible improvements:
 - concise README quickstart with common workflows
 - generated examples index
 - command cheat sheet
 - install/completion instructions
 - clearer diagnostics examples
 - `mkt extension` discovery guidance
 - optional docs generation workflow using `pdoc`
 Output: README/docs/examples polish and tests where executable.
 ## Exit Criteria
 - Every implemented subsystem has CLI access, public API access, docs, examples,
  and tests or a documented reason for omission.
 - Shell completion works for Bash, Zsh, and Fish through `mkt completion`.
 - `docs/cli-reference.md` and `docs/api-reference.md` can be regenerated from
  the live implementation.
 - Practical usecases are documented with relevance expectations and E2E coverage
  targets.
 - E2E tests cover small, typical, and large variations for the important
  workflows.
 - Full test suite passes.
