# Step 9 — catalog-thinning script (staged for the operator window).
#
# Renders the THIN-CATALOG end-state into a --workspace. NEVER mutates the live tree
# (forbidden_paths: plugins, shared, CLAUDE.md, README.md) — every write lands inside --workspace.
# After the operator window the catalog repo hosts only the marketplace manifest + the catalog-level
# docs; the 10 plugins + the design-system live in their own Forgejo repos under
# https://git.fromaitochitta.com/open/. This script produces that state for inspection/staging:
#
#   1. archives the tracked catalog (git archive HEAD) into --workspace (clean: no .git, no untracked)
#   2. removes plugins/, shared/, scripts/sync-design-system.mjs (+ its test)
#   3. extracts the marketplace conventions from CLAUDE.md into CONVENTIONS.md (D6)
#   4. thins the catalog CLAUDE.md to catalog-maintenance only
#   5. rewrites the landing README.md to point at the external plugin repos, re-stating every version
#      from plugin-map.json (the verified source). M15 is COUPLED to this D6 rewrite, not a ride-along:
#      a roster that re-states versions/counts must state the verified ones or it ships a false document.
#
# NULL push (D8): writes only inside --workspace.
#
# Usage: 70-thin-catalog.sh --workspace <dir>

# ktg-plugin-marketplace (catalog)

Catalog repository for the ktg-plugin-marketplace. After the polyrepo migration this repo hosts only
the marketplace manifest and the catalog-level docs; every plugin and the shared design-system live in
their own Forgejo repositories under `https://git.fromaitochitta.com/open/`.

## What lives here

- `.claude-plugin/marketplace.json` — the marketplace manifest (plugin entries point at external repos)
- `README.md` — the landing/catalog page
- `CONVENTIONS.md` — marketplace-wide conventions inherited by every plugin repo
- `GOVERNANCE.md` — governance + fork-and-own model
- `.mailmap`, `.gitleaks.toml`, `.gitleaksignore` — shared git-hygiene baselines

## Catalog maintenance

- Marketplace conventions: see CONVENTIONS.md.
- Adding/updating a plugin entry: edit `.claude-plugin/marketplace.json` (external `source: "url"` with
  a pinned `ref`) and re-state the plugin in README.md with its verified version.
- Plugin source, issues, and releases live in each plugin's own repository — not here.
