+# Manual QA
+
+Use this checklist before releasing changes to the Commit client. Never paste an
+API key into an issue, pull request, terminal recording, or chat.
+
+## OpenRouter account
+
+- Create a dedicated key for Commit and set a small spending limit.
+- Keep input/output logging and data-sharing disabled unless explicitly needed.
+- Disable routing to providers that train on prompts; enable zero-data-retention
+  routing when repository policy requires it.
+- Revoke and replace any key that has been exposed.
+
+References: [OpenRouter data collection](https://openrouter.ai/docs/guides/privacy/data-collection),
+[provider logging](https://openrouter.ai/docs/guides/privacy/provider-logging/), and
+[zero data retention](https://openrouter.ai/docs/guides/features/zdr).
+
+## Automated baseline
+
+Run from the repository root:
+
+```bash
+$ bash -n assets/sh/commit.sh
+$ go test ./...
+$ go test -race ./...
+$ go vet ./...
+$ git diff --check
+```
+
+Expected: every command exits successfully. The integration test verifies that
+the API key is not included in curl process arguments.
+
+If ShellCheck is installed, also run:
+
+```bash
+$ shellcheck assets/sh/commit.sh assets/sh/install.sh
+```
+
+## Local configuration
+
+Create or replace the configuration without putting the key in shell history:
+
+```bash
+$ ./assets/sh/commit.sh --setup
+$ stat -c '%a' ~/.config/commit ~/.config/commit/config.json
+$ jq -e 'keys == ["api_key"] and (.api_key | type == "string" and length > 0)' ~/.config/commit/config.json >/dev/null
+```
+
+On macOS, use `stat -f '%Lp'` for the permission checks. Expected directory and
+file modes are `700` and `600`. The JSON validation exits successfully without
+printing the key.
+
+Confirm that credentials were not committed:
+
+```bash
+$ git grep -n 'sk-or-v1-' -- ':!docs/manual-qa.md'
+```
+
+Expected: no matches.
+
+## Live dry run
+
+Use a disposable repository so the test cannot modify real work:
+
+```bash
+$ qa_root=$(mktemp -d)
+$ qa_repo="$qa_root/repo"
+$ mkdir "$qa_repo"
+$ cd "$qa_repo"
+$ git init -q
+$ printf 'manual QA\n' > qa.txt
+$ git add qa.txt
+$ /path/to/commit/assets/sh/commit.sh --dry-run
+```
+
+Expected:
+
+- OpenRouter returns a one-line Conventional Commit message.
+- The output lists `qa.txt` and does not create a commit.
+- The default request uses `google/gemini-2.5-flash-lite`.
+- The key and complete request body are never printed without `--verbose`.
+
+Repeat once with an advanced model override:
+
+```bash
+$ /path/to/commit/assets/sh/commit.sh --dry-run --model openrouter/auto
+```
+
+Expected: another valid message without changing the saved configuration.
+
+## Interactive commit
+
+Still inside the disposable repository, run without `--dry-run` and accept the
+message. Then verify the result:
+
+```bash
+$ /path/to/commit/assets/sh/commit.sh
+$ git log -1 --format='%s'
+$ git status --short
+```
+
+Expected: the selected message is the latest commit subject and the worktree is
+clean. Regenerate and suggestion choices may be tested with another staged dummy
+change; each regeneration makes another billable request.
+
+## Failure paths
+
+Verify these cases without using a real repository:
+
+- `--model` without a value exits with `--model requires a value`.
+- Missing configuration starts setup instead of sending a request.
+- Invalid JSON is rejected before any request.
+- Config mode `644` is rejected with the `chmod 600` instruction.
+- An invalid or revoked key returns OpenRouter's error and creates no commit.
+- A network stall ends within the configured 10-second connection and 60-second
+  total request timeouts.
+
+## Deployed endpoint
+
+After deployment:
+
+```bash
+$ curl -fsSL https://commit.jaw.dev/ | bash -s -- --help
+$ curl -fsSL https://commit.jaw.dev/install.sh | bash
+```
+
+Expected: HTTP failures stop the pipeline, help lists only OpenRouter settings,
+and the install script reports all required commands.
