A submodule that keeps its own `.git` directory, instead of one under `.git/modules/`, still shipped `sub/.git/config` into the build context, credential included. Both git patterns in the canonical `.dockerignore` now start with `**/`: `**/.git/config` and `**/.git/modules/**/config`.
A submodule whose name has a `config` segment (`config`, `deploy/config`, `config/lib`) still loses its whole git directory, because the pattern also matches that directory, and Go's version stamping then fails the build loudly. The file records this as a known gap with the way around it, `git submodule add --name`; closing it needs a wildcard re-include that makes every build walk excluded directories. `prompts/REPO_POLICIES.md` and both checklists say the same.

`ssh-keygen` names the private key of a key backed by a hardware security key `id_ecdsa_sk` or `id_ed25519_sk`. The canonical `.gitignore` and `.dockerignore` listed only `id_rsa`, `id_dsa`, `id_ecdsa` and `id_ed25519`, so a repository could commit these files or copy them into an image.
Both names are added beside their plain counterparts in each file's own style: unanchored in `.gitignore`, `**/`-prefixed in `.dockerignore`, case-folded with character ranges in both. A pattern matches the whole file name, so the `.pub` halves stay trackable and still reach the build context.

The canonical `.dockerignore` kept out `.git/config`, which can hold a credential, but not the `config` in each submodule's git directory under `.git/modules/`, nested again for a submodule's own submodules. It now also lists `.git/modules/**/config`, with one sentence in the comment above; `prompts/REPO_POLICIES.md` and both checklists say so in the same words.
The pattern stays under `.git/modules/` because `.git/**/config` would also drop a branch or tag named `config`, which `git describe` may need.
Known gap: a submodule whose name has a `config` path segment loses its whole git directory, so Go's version stamping fails the build loudly; tracked separately.

The canonical documents told every repo to exclude .git from the build
context, default ARG VERSION to dev and never run git describe in a
build stage, so an image built from a clone with no build argument
reported dev. .dockerignore now sends .git but keeps out .git/config,
which can hold a credential. The Dockerfile example installs git, takes
the VERSION build argument when one is given and otherwise
git describe --tags --always, and fails when .git exists but the version
is empty, dev or unknown. The policy and both checklists state the rule
in the same words, including that a plain docker build . with no build
arguments must succeed.

The canonical .dockerignore and .gitignore both omitted the in-repo agent
scratch directory, which holds one worktree per in-flight agent, so under
`COPY . .` an entire extra checkout of the repo reached the image. The
two entries are deliberately different shapes: anchored in .dockerignore,
where the `**/` form would also delete a legitimately named nested
directory, and unanchored in .gitignore, where a pattern already matches
at every depth. Anchoring leaves a gap where agents run in
subdirectories, stated in the vendored file itself. The second half is
the consequence of excluding .git: `git describe` in a build stage yields
an empty version without erroring, so the version is now computed on the
host and passed in.

The canonical .dockerignore was three lines while the canonical
Dockerfile does `COPY . .`, so a local .env, *.pem or *.key shipped into
the build context and could land in an image layer, invisible to every
git-based check. Copying .gitignore's patterns across is not the repair:
.dockerignore anchors an unprefixed pattern at the context root, so that
form protects only the repository root while reading as solved. Every
depth-independent pattern here carries `**/`, and secret names are
character ranges because matching is case-sensitive and an ALL-CAPS twin
still misses `Server.Key`. Public certificates are deliberately left in
as a legitimate build input. Verified by enumerating a probe image.

Add .gitignore, LICENSE (MIT), Makefile, Dockerfile, .dockerignore,
and pin prettier via yarn lockfile for integrity-checked markdown
formatting. Update REPO_POLICIES.md self-reference to point to this
repo. Format markdown files with prettier.
