Defame1297 38f1ba4e03 fix(kyberforge): bridge apm content to Claude Code's flat plugin discovery
Claude Code's (and Copilot's) native plugin installer has zero awareness of
.apm/ nesting -- it convention-scans only flat skills/, agents/, commands/,
hooks.json at each plugin's root. Confirmed via strings on the installed
claude binary and live installs of git@holocron/gitea@holocron/kyberforge@
holocron, all reporting Skills(0) Agents(0) Hooks(0) post ADR-0015's apm
conversion. Root cause (apm_cli/core/plugin_manifest.py): apm's plugin.json
compiler deliberately strips skills/agents/commands keys, assuming the host
already auto-discovers those convention directories -- it has no model of
.apm/ being host-visible at all. Separately, apm's own bundle exporter
(apm_cli/bundle/plugin_exporter.py, behind `apm pack --format plugin`)
implements the correct .apm/ -> flat mapping, but only ever targeted
build/<name>-<version>/, a path nothing in marketplace.json's source: points
at.

scripts/sync-plugin-content.sh wraps that bundle exporter and copies its
agents/, skills/, commands/, instructions/, extensions/, and merged
hooks.json back into each plugin's own root as a second tracked
compiled-output category -- same governance status as
.claude-plugin/plugin.json: generated from .apm/, never hand-edited. tests/
subdirectories are excluded from the mirror (dev fixtures, not host-visible
runtime content; several hardcode a relative repo-root walk-up sized for the
.apm/-nested depth, which breaks when duplicated one level shallower).
Applied for real across all 6 plugins and verified two ways: `claude plugin
validate --strict` passes on every real plugin directory, and a live
`claude --plugin-dir <path> -p "list skills/agents"` behavioral test
confirms content is now actually discovered.

Also, from the same issue #90 review round:
- scripts/check-manifests.sh pointed at each plugin's root-level plugin.json
  (checking skills/hooks/mcpServers/agents pointer fields) -- that file was a
  stale near-duplicate of .claude-plugin/plugin.json nothing else read or
  wrote, now deleted across all 6 plugins. check-manifests.sh is rewritten to
  validate .claude-plugin/plugin.json instead, and drops the pointer-field
  checks entirely (nothing to check -- those fields are correctly absent by
  design). Content-presence drift is now check-plugin-content-sync's job, a
  new pre-push hook wired in .pre-commit-config.yaml.

docs/adr/0017 records the root cause and decision in full, including two
rejected alternatives (patching plugin.json's path fields directly -- apm's
compiler strips them on every run; pointing marketplace.json at apm pack's
build/ output -- a version-suffixed non-source directory nothing can install
from without an extra build step). ADR-0015 and CONTEXT.md are updated to
point at it.

# Submodules — Deep Reference
## Update flag reference
| Flag | Meaning |
|---|---|
| `--init` | Run init first (avoids a separate step) |
| `--remote` | Use the submodule's remote branch tip instead of the superproject's recorded commit |
| `--checkout` | Detached HEAD at recorded commit (default) |
| `--rebase` | Rebase current branch onto recorded commit |
| `--merge` | Merge recorded commit into current branch |
| `--recursive` | Operate on nested submodules |
| `--jobs <n>` | Parallel clone (defaults to `submodule.fetchJobs`) |
| `-N` / `--no-fetch` | Skip remote fetch |
| `--depth <n>` | Shallow clone |
| `--filter <spec>` | Partial clone filter |
## Workflow patterns
### Clone a repo with submodules
```bash
git clone --recurse-submodules <url> # Git 2.13+, one step
# or
git clone <url>
git submodule update --init --recursive
```
### Add a dependency as a submodule
```bash
git submodule add https://github.com/org/lib.git libs/lib
git commit -m "chore: add lib as submodule"
```
### Keep submodules pinned to the superproject's recorded commit
```bash
git submodule update --recursive # after every git pull
git config submodule.recurse true # do this automatically on pull
```
### Update submodules to the latest commit on their tracked branch
```bash
git submodule update --remote --merge --recursive
git commit -am "chore: update submodules to latest"
```
### Override a submodule URL locally (private mirror)
```bash
git submodule init
# edit .git/config: submodule.<name>.url = <mirror-url>
git submodule update
```
Local-only override (`.git/config`, not `.gitmodules`) — doesn't propagate to collaborators. Re-running `sync` overwrites it with the `.gitmodules` URL.
## Removal, in full
`deinit` alone does not remove a submodule — it only clears `.git/config` and empties the working tree. To fully remove:
```bash
git submodule deinit -f <path> # unregister from .git/config
git rm <path> # remove .gitmodules entry + gitlink from index
rm -rf .git/modules/<name>/ # stale git dir; not tracked by git, not auto-cleaned
git commit -m "chore: remove <name> submodule"
```
`.git/modules/<name>/` persisting after `git rm` will block re-adding the same path until manually deleted.
## Relocate an embedded `.git` directory
```bash
git submodule absorbgitdirs [<path>...]
```
Moves a submodule's own `.git` directory into the superproject's `.git/modules/<name>/`, linking it back with a `.git` pointer file. Needed when a submodule was created or copied without going through `git submodule add` (e.g. converting a plain nested repo into a proper submodule).
## `foreach` shell variables
Available inside the `<command>` argument to `git submodule foreach`:
| Variable | Meaning |
|---|---|
| `$name` | Logical submodule name |
| `$sm_path` | Path relative to superproject root |
| `$displaypath` | Path relative to current working directory |
| `$sha1` | Recorded commit SHA |
| `$toplevel` | Superproject's root path |
```bash
git submodule foreach --recursive '<command>'
git submodule foreach 'git pull origin main || :' # || : continues past failures
```
