+# PX4 Conventional Commit
+
+Create a git commit: `type(scope): description`
+
+**NEVER add Co-Authored-By lines. No Claude attribution in commits.**
+
+Follow [CONTRIBUTING.md](../../CONTRIBUTING.md) for full project conventions.
+
+## Steps
+
+1. **Read [CONTRIBUTING.md](../../CONTRIBUTING.md)** for commit message format, types, scopes, and conventions.
+2. Check branch (`git branch --show-current`). If on `main`, create a feature branch. Use `<username>/<description>` format where `<username>` comes from `gh api user --jq .login`. If unavailable, just use `<description>`.
+3. Run `git status` and `git diff --staged`. If nothing staged, ask what to stage.
+4. Follow the commit message convention from CONTRIBUTING.md: pick the correct **type** and **scope**, write a concise imperative description.
+5. Body (if needed): explain **why**, not what.
+6. Run `make format` or `./Tools/astyle/fix_code_style.sh <file>` on changed C/C++ files before committing.
+7. Check if GPG signing is available: `git config --get user.signingkey`. If set, use `git commit -S -s`. Otherwise, use `git commit -s`.
+8. Stage and commit. No `Co-Authored-By`.

+3. PR **title**: `type(scope): description` — under 72 chars, describes the overall change across all commits. This becomes the squash-merge commit message.

+description: Rebase a branch onto main, handling squash-merged parent branches cleanly
+argument-hint: "[optional: branch name, defaults to current branch]"

+---
+
+# Rebase Branch onto Main
+
+Rebase the current (or specified) branch onto `main`, correctly handling the case where the branch was built on top of another branch that has since been squash-merged into `main`.
+
+## Background
+
+When a parent branch is squash-merged, its individual commits become a single new commit on `main` with a different hash. A normal `git rebase main` will try to replay the parent's original commits, causing messy conflicts. The fix is to **cherry-pick only the commits unique to this branch** onto a fresh branch from `main`.
+
+## Steps
+
+1. **Identify the branch.** Use `$ARGUMENTS` if provided, otherwise use the current branch.
+
+2. **Fetch and update main:**
+   ```
+   git fetch origin main:main
+   ```
+
+3. **Find the merge base** between the branch and `main`:
+   ```
+   git merge-base <branch> main
+   ```
+
+4. **List all commits** on the branch since the merge base:
+   ```
+   git log --oneline <merge-base>..<branch>
+   ```
+
+5. **Identify which commits are unique to this branch** vs. inherited from a parent branch. Look for:
+   - Squash-merged commits on `main` that correspond to a group of commits at the bottom of the branch's history (check PR titles, commit message keywords).
+   - The boundary commit: the first commit that belongs to *this* branch's work, not the parent's.
+   - If ALL commits are unique (no parent branch), just do a normal `git rebase main` and skip the rest.
+
+6. **Create a fresh branch from `main`:**
+   ```
+   git checkout -b <branch>-rebase main
+   ```
+
+7. **Cherry-pick only the unique commits** (oldest first):
+   ```
+   git cherry-pick <first-unique-commit>^..<branch>
+   ```
+   The `A^..B` range means "from the parent of A through B inclusive."
+
+8. **Handle conflicts** if any arise during cherry-pick. Resolve and `git cherry-pick --continue`.
+
+9. **Replace the old branch:**
+   ```
+   git branch -m <branch> <branch>-old
+   git branch -m <branch>-rebase <branch>
+   ```
+
+10. **Verify** the result:
+    ```
+    git log --oneline main..<branch>
+    ```
+    Confirm only the expected commits are present.
+
+11. **Ask the user** before force-pushing. When approved:
+    ```
+    git push origin <branch> --force-with-lease
+    ```
+
+12. **Clean up** the old branch:
+    ```
+    git branch -D <branch>-old
+    ```

+- `slpi.px4board` - QURT DSP (Hexagon)

 ## Build environment
 
 In order to build for this platform both the Qualcomm Hexagon (DSP) toolchain and the Linaro ARM64 toolchain need to be installed. The (nearly) complete setup including the ARM64 toolchain is provided in the base Docker image provided by ModalAI, but since ModalAI is not allowed to redistribute the Qualcomm Hexagon DSP SDK this must be added by the end user.

+A single `make modalai_voxl2` command builds both the DSP and apps processor
+firmware. The Makefile chains the SLPI build as a prerequisite of the default
