docs: clarify makerelease dry-run branch requirement

Add set -euo pipefail, root checks, safer orphan cleanup, and a help
message to fullupgrade. Refresh the README and project notes to match
the current scripts and release process.

+# Project status — fullupgrade
+
+Last updated: 2026-04-27
+
+## Project goal
+This repository contains two Bash scripts for system administration and Git release management:
+- `fullupgrade`: Arch Linux maintenance script
+- `makerelease.sh`: Git release automation script
+
+The project is intentionally minimal and centered on these two scripts.
+
+## Current structure
+- `fullupgrade`: system update and cleanup
+- `makerelease.sh`: release workflow from `dev` to `main`
+- `README.md`: English documentation with usage, warnings, and examples
+- `LICENSE`: GPLv3
+
+## Current analysis
+
+### 1) `fullupgrade`
+Current behavior:
+- updates `archlinux-keyring`
+- runs `pacman -Syu --noconfirm`
+- removes orphaned packages only when any are found
+- cleans the pacman cache
+
+Notes:
+- the script already uses `set -euo pipefail`
+- it checks for root privileges before running package operations
+- it can have a significant system impact
+
+Recommendations:
+- keep documenting the system impact clearly
+- consider whether `pacman -Sc` is the right cache cleanup level for every use case
+
+### 2) `makerelease.sh`
+Current behavior:
+- takes `VERSION` and `MESSAGE` as arguments
+- checks that the current branch is `dev`
+- checks out `main`
+- merges `dev` into `main`
+- pushes the branch
+- creates an annotated tag
+- pushes tags
+- returns to `dev`
+
+Notes:
+- the script currently does not use `set -euo pipefail`
+- there is no check for a clean working tree
+- there is no validation of the release message
+- there is no guard against duplicate tags
+- returning to `dev` is not protected if a command fails
+
+Recommendations:
+- add `set -euo pipefail`
+- verify the Git status before releasing
+- validate `VERSION` and `MESSAGE`
+- prevent duplicate tags
+- use a `trap` to return to the initial branch on failure
+- improve the help output
+
+### 3) `README.md`
+Current status:
+- the README has a first complete pass in English
+- it explains both scripts, their requirements, usage, warnings, and an example release command
+
+Recommendations:
+- keep it aligned with the actual script behavior
+- add more examples only if they improve clarity
+
+## Project tracking rules
+This file should be updated whenever:
+- script behavior changes
+- documentation changes materially
+- new constraints or design decisions are introduced
+- release workflow rules evolve
+
+## Current priorities
+1. Secure the Bash scripts
+2. Keep documentation aligned with the scripts
+3. Make the release workflow more robust
+
+## Maintenance notes
+- Always keep the README, the scripts, and this file consistent.
+- If a script changes, update this note immediately.
+- If a new usage rule appears, document it here.

 # fullupgrade
 
+Minimal Bash tools for Arch Linux maintenance and Git release automation.
+
+## Overview
+
+This repository contains two small Bash scripts:
+
+- `fullupgrade`: updates an Arch Linux system and performs cleanup
+- `makerelease.sh`: automates a Git release from `dev` to `main`
+
+The project is intentionally small and focused on a simple, opinionated workflow.
+
+## Requirements
+
+- Bash
+- `pacman` for `fullupgrade`
+- `git` for `makerelease.sh`
+- root privileges for `fullupgrade`
+- a local Git repository with `dev` and `main` branches for `makerelease.sh`
+
+## `fullupgrade`
+
+`fullupgrade` performs the following steps:
+
+1. updates `archlinux-keyring`
+2. runs a full system synchronization with `pacman -Syu --noconfirm`
+3. removes orphaned packages if any are found
+4. cleans the pacman cache with `pacman -Sc --noconfirm`
+
+### Usage
+
+```bash
+sudo ./fullupgrade
+```
+
+### Notes
+
+- The script must be run as `root`.
+- It does not ask for confirmation.
+- It can remove packages and clean the package cache, so review the output carefully.
+
+## `makerelease.sh`
+
+`makerelease.sh` automates a Git release workflow:
+
+1. checks that the current branch is `dev` for real releases
+2. verifies the working tree is clean
+3. optionally computes a new version from an increment shortcut
+4. switches to `main`
+5. merges `dev` into `main`
+6. pushes `main`
+7. creates an annotated tag
+8. pushes tags
+9. switches back to the original branch on exit
+
+### Usage
+
+```bash
+./makerelease.sh VERSION
+./makerelease.sh +0.0.1
+./makerelease.sh +0.1
+./makerelease.sh +1
+./makerelease.sh --dry-run VERSION
+./makerelease.sh --dry-run +0.0.1
+./makerelease.sh --dry-run +0.1
+./makerelease.sh --dry-run +1
+```
+
+### Examples
+
+```bash
+./makerelease.sh 1.2.0
+./makerelease.sh --dry-run +0.0.1
+```
+
+### Notes
+
+- Run the script from a clean, local Git repository.
+- Make sure the `dev` branch contains the changes you want to release.
+- `VERSION` is used directly as the tag name.
+- If `VERSION` starts with `+`, it is treated as an increment based on the latest existing tag.
+- `--dry-run` can be used from any branch and only prints the computed tag.
+- The script may fail if Git state is unexpected or if a tag already exists.
+- The tag message is automatically generated as `Release <version>`.
+
+## Status
+
+This repository is intentionally minimal.
+- `fullupgrade` is hardened with `set -euo pipefail`.
+- `makerelease.sh` now includes clean-tree checks, duplicate tag protection, increment shortcuts, dry-run support from any branch, and a trap to return to the original branch on exit.

+## Current structure
+- `fullupgrade`: system update and cleanup

+Current behavior:
+- supports explicit versions like `1.2.3`
+- supports version increments with `+0.0.1`, `+0.1`, and `+1`
+- supports `--dry-run` to print the computed release version

+
+Notes:
+- the script uses `set -euo pipefail`
+- the release tag message is now generated automatically as `Release <version>`
+- the script no longer requires a separate release message argument
+- the current increment logic assumes simple dotted numeric tags
+
+Recommendations:
+- consider whether tags may need a `v` prefix in the future
+- consider validating the version format more strictly if release rules grow
+- keep the dry-run behavior documented and aligned with the script
+
+### 3) `README.md`
+Current status:
+- the README documents both scripts in English
+- it now includes release increments and dry-run usage for `makerelease.sh`
+
+Recommendations:
+- keep it aligned with the actual script behavior
+- add more examples only if they improve clarity
