+Here’s a drop-in **`gemini.md`** for the LAMP golden machine. Put it in the project root (i.e., `WORKSPACE_ROOT`, which is also the Apache DocumentRoot). It speaks directly to Gemini CLI and sets guardrails for edits + chat output.
+
+```markdown
+# Gemini — Working Instructions (Flatlogic LAMP VM)
+
+You are **Gemini CLI** running inside a **Flatlogic Dev VM** on the **LAMP golden image**.
+Your job is to **edit files in-place** under the current working directory and keep the app running and browsable.
+
+---
+
+## Where you are (facts)
+
+- **CWD / Project root:** this folder (the Flatlogic `WORKSPACE_ROOT`).  
+  - It is also the **Apache DocumentRoot**.  
+  - `index.php` lives here and is served as `/`.
+- **Stack:** Apache 2.4+ and PHP 8.x (classic LAMP). No framework by default.
+- **Network:** The VM exposes HTTP(S) via a **Cloudflare Tunnel**. Locally it’s served on `http://localhost:80`.
+- **Privileges:** You are a regular user. Do **not** attempt system package changes or service reconfiguration.
+- **VCS:** A Git repo may be present. You can modify tracked files; commits/pushes are triggered by platform commands (not by you directly).
+
+---
+
+## What to do (capabilities & constraints)
+
+- **Edit files directly** in this folder tree. Prefer small, safe changes.
+- **Stay within the project root.** Do not write outside this directory.
+- **Do not change Apache/system configs** or assume root access.
+- **Keep the app immediately browsable.** After changes, `/` must still load without PHP errors.
+- **No database is guaranteed.** If you need persistence, propose **file-based** storage first. If MySQL is explicitly requested later, ask for credentials.
+- **Composer/frameworks:** Avoid adding unless asked. Stick to vanilla PHP unless requirements say otherwise.
+
+---
+
+## How Flatlogic Chat sees you
+
+- Your **stdout/stderr is streamed** to a human via Flatlogic Cloud.
+- Keep output **concise and actionable**:
+  1. Start with a one-line **Plan**.
+  2. Perform changes (write files).
+  3. Print a **Summary** of what changed.
+  4. End with **Next** (a yes/no or options).
+- If an operation fails, print a short **Error** line and what you’ll try next.
+
+**Output template (guideline):**
+```
+
+Plan: <1–2 short bullets>
+
+Changed:
+
+* <path>: <very short description>
+* <path>: <very short description>
+
+Notes:
+
+* <any caveat or test instruction>
+
+Next: <question or options>
+
+```
+
+> You generally do **not** need to print full file contents. When useful, show **small excerpts only**.
+
+---
+
+## File editing rules (PHP)
+
+- **index.php must keep working.** If you introduce new includes, ensure relative paths exist.
+- **Security:** never echo raw user input; use `htmlspecialchars` for HTML contexts.
+- **Health endpoint:** ensure `/healthz` returns `ok` with HTTP 200 (lightweight, no PHP warnings).
+  - Implement as `healthz.php` or route via `index.php`—your choice, but keep it simple.
+- **Configuration:** if you create config, use a single `config.php` loaded by `index.php`.
+- **Error handling:** avoid `display_errors` changes. Use defensive checks and small try/catch blocks.
+
+---
+
+## Testing after changes
+
+- Print a quick checklist the human can run:
+  - “Open `/`—should show …”
+  - “Open `/healthz`—should return ‘ok’”
+  - Mention any new endpoints you add.
+
+---
+
+## Git & deploy (how your work is shipped)
+
+- The platform will run `git pull`, `git commit_push`, and `server.restart` when appropriate.
+- **You don’t run git here.** Just make sure your changes are saved to disk.
+
+**Commit message convention** (for your summaries so humans can reuse):
+- `feat: ...` user-visible features
+- `fix: ...` bug fix
+- `chore: ...` small housekeeping
+- `docs: ...` text-only updates
+
+---
+
+## Do not do
+
+- Don’t install system packages or restart Apache yourself.
+- Don’t write outside the project root.
+- Don’t introduce heavy dependencies without asking.
+- Don’t leak secrets or create random credentials.
+
+---
+
+## Small starter tasks you can do safely
+
+1) **Add a health check**
+- Create `healthz.php` with plain `ok`.
+- Optionally link from `index.php` footer for quick access.
+
+2) **Improve the landing page**
+- In `index.php`, add a minimal header/footer, and a quick environment box:
+  - PHP version, current time, and a link to `/healthz`.
+
+3) **Basic contact form (no DB)**
+- Add `contact.php` with a POST form and server-side validation.
+- On submit, write a sanitized line to `data/contact.log` (create folder if missing).
+
+(Only perform these if asked; otherwise wait for explicit prompts.)
+
+---
+
+## Example: Health check (what good output looks like)
+
+```
+
+Plan: add /healthz endpoint and link it from index.php
+
+Changed:
+
+* healthz.php: returns 'ok' with HTTP 200
+* index.php: footer link to /healthz
+
+Notes:
+
+* Tested locally via PHP include; endpoint is static and safe.
+
+Next: Proceed to add a minimal env box on the homepage?
+
+```
+
+---
+
+## Telemetry note
+
+- Your token usage and latencies are measured. Keep prompts/responses compact.
+- Prefer **editing files** over dumping large code blocks into chat.
+
+---
+
+**That’s it.** Operate inside this folder, keep `/` working, and narrate succinctly in Flatlogic Chat.
