[Extension]: Update OKF Knowledge Bundle Generator to v0.9.2 (moved to catalogify)

Start with docs/community/extensions.md and locate the catalog data containing the okf entry. Compare the proposed catalog entry with the issue details, update the catalog and the documentation row, then verify that the catalog metadata and both URLs point to catalogify and its v0.9.2 release.

Extension ID

okf

Extension Name

OKF Knowledge Bundle Generator

Version

0.9.2

Description

Generates and maintains an Open Knowledge Format (OKF v0.1) knowledge bundle from a source-code repository. Mines git history for the rationale behind the code, parks what it cannot establish as open questions rather than guessing, and verifies that the bundle's claims are actually supported by the repository.

Key Features

• Generates a conformant OKF v0.1 bundle: cross-linked markdown concepts with YAML frontmatter for services, modules, APIs, data models and operations
• Mines git history for design rationale, following reverts back to the commit they reverted and marking test-only commits, so invariants recorded nowhere else are captured with commit citations
• Parks what it cannot establish as open_questions instead of guessing; /speckit.okf.clarify folds human answers back in behind sentinels that later updates will not overwrite
• Incremental /speckit.okf.update diffs since the last logged commit and refreshes only affected concepts, deprecating rather than deleting
• /speckit.okf.validate enforces the OKF §9 conformance rules; /speckit.okf.verify checks the bundle's claims: every cited commit exists and belongs to the concept citing it, every named interface exists in non-test code, every source path is tracked by git

Testing Checklist

• No security vulnerabilities identified
• Tested on at least one real project

Submission Requirements

• Valid extension.yml manifest included
• README.md with installation and usage instructions
• LICENSE file included
• GitHub release created with version tag
• All command files exist and are properly formatted
• Extension ID follows naming conventions (lowercase-with-hyphens)

Testing Details

Tested on: Linux, Python 3.10 and 3.11, specify 0.12.18.

 **Release archive verified:** downloaded from the URL above (release [v0.9.2](https://github.com/alexcpn/catalogify/releases/tag/v0.9.2)), SHA-256
 `b426c135dc2d6c6bd11b286c70273f5ae28db5d2a2252acd9768cfb893b9b303`. `extension.yml` sits at the top of the archive and declares version 0.9.2. All five declared command files are
 present, as are the four scripts and the config template.

 **Test scenarios:**
 1. `specify extension add okf --from <download URL>` (the real release URL) in a fresh `specify init --integration claude` project: all five commands register, with descriptions,
 and the scripts land under `.specify/extensions/okf/scripts/`.
 2. The installed scripts run as the commands invoke them (`bash …/okf-inventory.sh`, `bash …/okf-history.sh`, `python3 …/validate_okf.py`, `python3 …/verify_okf.py`).
 3. Real project: `GoogleCloudPlatform/microservices-demo`, a full clone with 1,946 commits and an existing 28-concept bundle. Run from the installed extension, the inventory scan
 completes; history mining on `src/cartservice` returns 304 commits; co-change mining analyses 1,946 commits; `validate_okf.py knowledge` reports `RESULT: CONFORMANT (OKF v0.1)`;
 and `verify_okf.py knowledge` reports `RESULT: VERIFIED` with two V6 notes about runtime coupling.
 4. Installed into an existing Spec Kit project that uses the Claude integration. The five `/speckit-okf-*` skills register and run.

 **Changes since 0.5.0:**

 - **New command `/speckit.okf.verify`.** It checks claims rather than structure: cited commits must exist, belong to the concept citing them and not be test-only; symbols in `#
 Interfaces` must appear in non-test source; `source_files` must be tracked by git; invariants need evidence. Running generate twice against `kubernetes/kubernetes` produced the
 same five wrong claims both times. They were test-only commits written up as production invariants, and verify catches all five.
 - **Fixed: scripts failed with "permission denied" after a zip install.** Spec Kit extracts archives without file modes, and the commands ran the shell scripts directly. They now
 run them through `bash`.
 - History mining lists the files each commit touched and warns when the clone is shallow. New co-change mining finds directories that always change together. Untracked (vendored)
 subtrees are refused. Cross-links are relative so they resolve on GitHub, and bundles carry a `README.md`.
 - Each command now has a description in the manifest, so `specify extension add` lists them properly.

Example Usage

specify extension add okf --from https://github.com/alexcpn/catalogify/releases/download/v0.9.2/speckit-okf-0.9.2.zip

/speckit.okf.generate   # bootstrap knowledge/ from code and git history
/speckit.okf.clarify    # answer the questions it parked instead of guessing
/speckit.okf.update     # after code changes, refresh incrementally
/speckit.okf.validate   # OKF conformance
/speckit.okf.verify     # are the bundle's claims supported by the repository?


In Claude Code and Codex these register as `/speckit-okf-generate`, `/speckit-okf-verify` and so on.

Additional Context

Please also update the okf row in docs/community/extensions.md: its URL column links alexcpn/speckit_okf and should link catalogify.

An earlier update to 0.6.0 was posted as a comment on #4439 after that issue had closed, and never reached the catalog. This submission replaces it.
