 # profile
+
 This project aims to create an advanced bash profile. It includes aliases,
 a customized prompt and several functions for different purposes. It's mostly
 targeted to system administrators but might satisfy some regular users.
 
 ## 1. Requirements
+
 profile requires **Bash 4.3 or higher** (for associative arrays and namerefs).
 It will refuse to load on older versions and will also refuse to load if the
 current shell is not bash.
 
 ## 2. Getting started
+
 Download and extract (or use git clone) the profile archive into your home
-directory. You will have to modify your `~/.bashrc` and/or `~/.profile` file to
-add at the end (preferably):
+directory.
+
+The profile is designed to be **sourced**, not executed directly.
+
+Manual setup:
+
 ```bash
 source <installpath>/profile/profile.sh
 ```
 
+Automatic setup (recommended):
+
+```bash
+bash <installpath>/profile/profile.sh --install
+```
+
+`--install` appends the required `source` line to both `~/.bashrc` and
+`~/.profile` by default. You can target one file only:
+
+```bash
+bash <installpath>/profile/profile.sh --install --bashrc
+bash <installpath>/profile/profile.sh --install --profile
+```
+
 You may also set the `PROFILE_PATH` environment variable before sourcing if you
 want to override the automatic path detection:
+
 ```bash
 export PROFILE_PATH=/opt/profile
 source /opt/profile/profile.sh
@@ -26,56 +48,93 @@ source /opt/profile/profile.sh
 It's not recommended to load that profile in `/etc/profile` as users' `.bashrc`
 files might interfere with some aliases and functions defined in profile.
 
-### 2.1. Initial configuration
+### 2.1. Interactive vs non-interactive shells
+
+`profile.sh` detects whether the current shell is interactive.
+
+In interactive shells (typical terminal sessions), profile enables
+interactive-only features such as:
+
+- aliases from `[aliases]`
+- bash completion scripts from `profile.d/bash-completion/`
+- prompt initialization (`PROMPT_COMMAND` and timer hook)
+- welcome display (`showinfo`) and startup update check (`check_updates -q`)
+
+In non-interactive shells (typical script execution), those features are
+intentionally skipped to avoid side effects and startup noise. Public functions
+remain available after sourcing, so scripts can still call profile helpers.
+
+### 2.2. Initial configuration
+
 Copy the example configuration file and customise it to your needs:
+
 ```bash
 cp <installpath>/profile/doc/profile.conf.example <installpath>/profile/profile.conf
 ```
+
 `profile.conf` is git-ignored so your personal settings will never be
 accidentally committed. All keys are optional — sensible defaults apply when
 unset. See [section 4](#4-configuration) for the full reference.
 
 ## 3. What's the purpose?
+
 profile gives access to numerous functions, aliases and to an advanced prompt.
 All functions are organized into modules under the `profile.d/` directory and
 are loaded automatically at startup.
 
 ### 3.1. Prompt
+
 A bar-style prompt showing current time, execution time of the last command
 (with sub-millisecond precision), and the exit code of the last command.

-## [3.99.1-4_rc_1] — 2026
-
-### Added
-- **Theming system** — `load_theme` in `profile.d/prompt.sh` loads `.theme`
-  files from `profile.d/themes/` (or a custom directory set via
-  `PROMPT_THEME_DIR`). Theme files are **parsed, not executed** — no shell code
-  ever runs from a theme.
-- **Built-in themes** — `default`, `dark`, `light`, `solarized` (24-bit
-  true-colour), `solarized-light` (24-bit), `monokai`, `monochrome`, `abyss`,
-  `plasma`, `adwaita`.
-- **`[prompt]` section** — `PROMPT_THEME` and `PROMPT_THEME_DIR` keys to select
-  a theme; eleven `PROMPT_COLOR_*` keys for per-key overrides in `profile.conf`.
-- **Standard colour variables as theme keys** — theme files may also override
-  the `disp.sh` colour variables (`Black`, `Blue`, `On_IBlack`, …) to remap the
-  terminal palette used by `ls`, `grep`, and colour-aware tools.
-- **Module configuration defaults** — all modules now expose their hardcoded
-  defaults as `profile.conf` keys: `TAZ_*`, `UTAZ_*`, `EXPANDLIST_*`,
-  `CLEAN_*`, `RMSPC_*`, `FINDBIG_*`, `RAIN_*`, `MATRIX_*`, `SSH_DEFAULT_OPT`,
-  `GENPWD_*`, `PWDSCORE_*`, `BUSY_*`, `METEO_DEFAULT_CITY`, `DWL_*`,
-  `MYEXTIP_*`, `PKGS_*`, `PPU_*`, `KU_*`, `UPDT_DEFAULT_BRANCH`.
-- **`UPDT_DEFAULT_BRANCH`** — configures the git branch used by `check_updates`
-  and `profile_upgrade`. Changing the key causes `profile_upgrade` to
-  automatically switch the local checkout to the new branch and display a
-  warning.
-- **`doc/` directory** — `CONTRIBUTING.md`, `FAQ.md`, `profile.conf.example`
-  (annotated template), `todo.md`.
-- **`.gitignore`** — `profile.conf` is now git-ignored so personal settings are
-  never accidentally staged.
-
-### Changed
-- README §2 now explains how to create `profile.conf` from
-  `doc/profile.conf.example` (new section 2.1 "Initial configuration").
-- README §4 updated with full module-defaults tables, theming reference, and a
-  note about `profile.conf` being git-ignored.
-- Theme values no longer carry the `export` keyword (they are not shell
-  variables, only data).
-
-### Security
-- `load_theme` uses a strict allowlist (no `eval`, no sourcing). Only
-  `PROMPT_COLOR_*` keys and known `disp.sh` colour variable names are accepted.
-  Values must match `\$[A-Za-z_][A-Za-z0-9_]*` or `\\e\[[0-9;]*m`; any other
-  value is discarded with a warning.

+
+All notable changes to this project will be documented in this file.
+
+The format follows [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
+Versions follow `MAJOR.MINOR.PATCH-REVISION_STAGE_N` (e.g. `3.99.1-4_rc_1`).
+
+---
+
+## [4.1.0] — 2026-05-07
+
+### Added
+
+- `profile.sh --install` command to automatically configure profile loading in
+  shell startup files.
+- `--install --bashrc` and `--install --profile` target selectors for
+  single-file installation.
+- **`git.sh`** — entirely new module providing git workflow helpers: `gst`,
+  `ggraph`, `gsync`, `gacp`, `greset`, `gwip`, `gprune`, `groot`.
+- Dedicated git helper completions under `profile.d/bash-completion/`, loaded
+  automatically in interactive sessions from `profile.d/bash-completion/*.sh`.
+
+### Changed
+
+- `disp` now wraps long messages on terminal width, avoids mid-word splits, and
+  aligns continuation lines with the message body after the prefix.
+- `help` now supports `help <command>` and delegates to `<command> --help`.
+- `taz` now supports `-p auto` / `--parallel=auto` to automatically use the
+  runtime CPU count. This mode is now the default via
+  `TAZ_DEFAULT_THREADS=auto`. Backward compatibility with 0 being interpreted as
+  auto is maintained.
+
+### Fixed
+
+- Startup responsiveness improved: `check_updates -q` now uses a short network
+  timeout so unavailable/slow networks no longer delay prompt readiness.
+- `dwl` gained timeout support (`-t` / `--timeout`) and is now used by quiet
+  startup update checks to enforce fast failure.
+- `profile.sh` now detects direct execution and warns that it is designed to be
+  sourced.
+
+## [4.0.0] — 2026-04-23
+
+### Added
+
+- New `profile.conf` reference template at `doc/profile.conf.example`.
+- Dynamic locale shortcuts generated from `SET_LOCALE` and startup default
+  language selection through `DEFAULT_LANG`.
+- Prompt theming system with bundled themes (`default`, `dark`, `light`,
+  `solarized`, `solarized-light`, `monokai`, `monochrome`, `abyss`, `plasma`,
+  `adwaita`) and per-key prompt color overrides.
+- Module defaults exposed as configuration keys in `profile.conf`.
+
+### Changed
+
+- `utaz` now supports a wider range of archive formats.
+- Prompt and theme rendering improved, including better 24-bit color support.
+- Overall code quality and maintainability improved across modules.
+
+### Documentation
+
+- README updated with full function reference and configuration tables.
+- New and expanded docs in `doc/` (`CONTRIBUTING.md`, `FAQ.md`, `todo.md`).
+- Historical releases imported from `history.txt` into this changelog.
+
+---
+
+## [3.99.2-4_rc_2] — 2026-04-21
+
+### Fixed
+
+- **`prompt.sh`** — `\$Last_Command` in PS1 was escaped, preventing the exit
+  code from ever appearing in the prompt (the local variable no longer exists
+  when PS1 is rendered by bash). Removed the backslash so the value is embedded
+  at `set_prompt` build time.
+- **`filefct.sh` — `file_stats()`** — a stray unconditional `shift` after
+  `esac` doubled-shifted arguments already shifted by each `case` branch;
+  successive options such as `-H -d` were silently skipped.
+- **`packages.sh` — `pkgs()`** — replaced the unreliable binary-presence test
+  (`command -v dpkg / rpm`) with the new `get_pkgmgr` function. Also corrected
+  a typo in the "no package manager" error message (`avialable` → `available`).
+- **`processes.sh` — `kt()`** — copy-paste error: usage error message read
+  `"Usage: ppg <string>"` instead of `"Usage: kt <pid>"`.
+
+### Added
+
+- **`packages.sh` — `get_pkgmgr()`** — new exported helper that detects the
+  active package manager of the running distribution. Detection first reads
+  `/etc/os-release` (`ID` then `ID_LIKE`), then falls back to a
+  fixed-priority binary scan. Supported families: `apt`, `dnf`, `yum`,
+  `zypper`, `pacman`, `apk`, `portage`, `xbps`, `nix`. Returns 1 when
+  nothing is identified. Available to all future commands in `packages.sh`.
+
+---
+
+## [3.99.1-4_rc_1] — 2026
+
+### Added
+
+- **Theming system** — `load_theme` in `profile.d/prompt.sh` loads `.theme`
+  files from `profile.d/themes/` (or a custom directory set via
+  `PROMPT_THEME_DIR`). Theme files are **parsed, not executed** — no shell code

+  true-colour), `solarized-light` (24-bit), `monokai`, `monochrome`, `abyss`,
+  `plasma`, `adwaita`.
+- **`[prompt]` section** — `PROMPT_THEME` and `PROMPT_THEME_DIR` keys to select
+  a theme; eleven `PROMPT_COLOR_*` keys for per-key overrides in `profile.conf`.
+- **Standard colour variables as theme keys** — theme files may also override
+  the `disp.sh` colour variables (`Black`, `Blue`, `On_IBlack`, …) to remap the

+  `GENPWD_*`, `PWDSCORE_*`, `BUSY_*`, `METEO_DEFAULT_CITY`, `DWL_*`,
+  `MYEXTIP_*`, `PKGS_*`, `PPU_*`, `KU_*`, `UPDT_DEFAULT_BRANCH`.
+- **`UPDT_DEFAULT_BRANCH`** — configures the git branch used by `check_updates`
+  and `profile_upgrade`. Changing the key causes `profile_upgrade` to
+  automatically switch the local checkout to the new branch and display a
+  warning.
+- **`doc/` directory** — `CONTRIBUTING.md`, `FAQ.md`, `profile.conf.example`
+  (annotated template), `todo.md`.
+- **`.gitignore`** — `profile.conf` is now git-ignored so personal settings are
+  never accidentally staged.
+

-# Contributing to profile
-
-Thank you for your interest in contributing. This document explains how to get
-set up, what the conventions are, and how to submit work.
-
----
-
-## 1. Before you start
-
-- Check the [to-do list](./todo.md) to see if your idea is already planned.
-- Check the [issue tracker](https://git.geoffray-levasseur.org/fatalerrors/profile/issues)
-  to avoid duplicate work.
-- For significant changes, open an issue or contact the maintainer before
-  writing code — alignment on design saves everyone time.
-
----
-
-## 2. Getting the source
-
-A Git clone is mandatory for contributions:
-
-```bash
-git clone https://git.geoffray-levasseur.org/fatalerrors/profile.git
-cd profile
-```
-
-Always work from the **latest commit on `master`** (or the branch you intend
-to target). Stale forks cause avoidable merge conflicts.
-
----
-
-## 3. Development environment
-
-| Requirement | Minimum version | Notes |
-|---|---|---|
-| Bash | 4.3 | Namerefs (`local -n`) required |
-| shellcheck | any recent | Run before every commit |
-| git | any | For contributing patches |
-| bats-core | 1.x | Optional — for running the test suite |
-
-Install shellcheck:
-```bash
-# Debian / Ubuntu
-apt-get install shellcheck
-
-# Fedora / RHEL
-dnf install ShellCheck
-
-# macOS
-brew install shellcheck
-```
-
----
-
-## 4. Code style
-
-### General rules
-- **Bash only** — no external interpreters in core modules. Python or Perl is
-  acceptable for completely self-contained, optional utilities that have no
-  dependencies beyond a minimal Debian or CentOS installation.
-- **4-space indentation** — no tabs.
-- **`[[ … ]]`** for all conditionals — not `[ … ]`.
-- **`(( … ))`** for arithmetic — not `$(( … ))` in conditionals.
-- **`local`** for all function-internal variables — avoid polluting the
-  environment.
-- **`printf`** instead of `echo` wherever the format matters.
-- **Never `eval`** — use namerefs (`local -n`), `${!varname}` indirection, or
-  `declare -g` instead.
-- **No hardcoded defaults** — wire every configurable value through
-  `${VAR:-default}` and document the key in `profile.conf` and `README.md §4`.
-
-### Function conventions
-- Public functions **must** be exported: `export -f funcname`.
-- Every public function **must** support `-h` / `--help` and print usage to
-  stdout, returning 0.
-- Use `getopt` (not `getopts`) for option parsing — it handles long options and
-  `--` correctly.
-- Follow existing error-return conventions: 0 = success, 1 = usage error,
-  2 = bad options, 3 = missing dependency, 4+ = runtime failure.
-- Prefix all local helper variables with a short unique prefix (e.g. `_taz_`)
-  to prevent collisions with caller-scope variables.
-
-### Module structure
-Every new module should follow this pattern:
-
-```bash
-#!/usr/bin/env bash
-# <copyright block identical to existing modules>
-
-load_conf "<module_name>"
-
-# --- functions ---
-
-export -f my_function
-
-# EOF
-```
-
-Add the `load_conf` call near the top after any variable declarations.
-
----
-
-## 5. Configuration keys
-
-When adding a configurable default:
-
-1. Use `${MY_VAR:-hardcoded_default}` in the function body.
-2. Add a commented-out entry with a description to `profile.conf`.
-3. Document the key in the matching table in `README.md §4.2`.
-
----
-
-## 6. Theming
-
-New theme files go in `profile.d/themes/` with a `.theme` extension.
-They are **parsed, not executed** — do not add shell logic.  
-See the existing themes and `README.md §4.4` for the allowed syntax.
-
----
-
-## 7. Running shellcheck
-
-```bash
-shellcheck -x profile.sh profile.d/*.sh
-```
-
-All warnings must be resolved before a patch will be accepted. Accepted
-suppression directives (`# shellcheck disable=SCxxxx`) require an inline
-comment explaining why the suppression is necessary.
-
----
-
-## 8. Submitting a contribution
-
-### Via Git (preferred)
-1. Contact the maintainer to obtain push access, or fork on the Gitea instance.
-2. Create a branch: `git checkout -b feature/my-feature`.
-3. Commit with a clear subject line: `module: short description (≤ 72 chars)`.
-4. Push and open a pull request against `master`.
-
-### Via patch
-If you do not have push access:
-```bash
-git format-patch origin/master
-```
-Send the resulting `.patch` file(s) to
-`fatalerrors <at> geoffray-levasseur <dot> org`.
-
-### Commit message format
-```
-module: imperative short description
-
-Optional longer explanation of what changed and why. Wrap at 72 characters.
-Reference issue numbers if applicable: closes #42.
-```
-
----
-
-## 9. What will be rejected
-
-- Code requiring packages not in a minimal Debian or CentOS install.
-- Use of `eval`, `source`-based config loading, or other code-injection vectors.
-- Changes that break Bash 4.3 compatibility.
-- Patches without a passing `shellcheck` run.
-- New functions without `--help` support.

+
+---
+
+## 1. Before you start
+
+- Check the [to-do list](./todo.md) to see if your idea is already planned.
+- Check the [issue tracker](https://git.geoffray-levasseur.org/fatalerrors/profile/issues)
+  to avoid duplicate work.
+- For significant changes, open an issue or contact the maintainer before

+
+## 2. Getting the source
+
+A Git clone is mandatory for contributions:

+cd profile
+```
+
+Always work from the **latest commit on `master`** (or the branch you intend
+to target). Stale forks cause avoidable merge conflicts.
+
+---
+
+## 3. Branch policy
+
+| Branch | Purpose |
+|---|---|
+| `master` | Main development branch — new features and enhancements go here |
+| `<version>` (e.g. `3.x`) | Maintenance branch for a released version — bugfixes backported from `master` |
+
+**New functionality** must always target `master`.
+
+**Bugfixes** must target the branch where the bug was introduced:
+
+- If the bug exists in a released version, open the fix against that version's
+  maintenance branch first, then cherry-pick onto `master`.
+- If the bug is only in `master` (unreleased), fix it directly on `master`.
+- During a release-candidate cycle, bugfixes go on the `x.*` branch and are
+  merged back into `master` before the final release.
+
+Do **not** add new features to a maintenance branch.
+
+---
+
+## 4. Versioning scheme
+
+Versions follow the format **`MAJOR.MINOR.PATCH`** where the `MINOR` number
+conveys the development stage of the next major release:
+
+| Minor range | Stage | Rules |
+|---|---|---|
+| `x.90.y` | **Alpha** toward `x+1` | Stays on `master`. Development is open: new features are welcome, regressions are acceptable. |
+| `x.95.y` | **Beta** toward `x+1` | The `x+1.*` maintenance branch is created at this point. No regression unless absolutely necessary; new features still allowed. |
+| `x.99.y` | **RC** toward `x+1` | Bugfixes only. No new features. No regression allowed. Becomes `x+1.0.0` when stable. |
+
+Examples: `3.90.1` is the first alpha toward `4.0`, `3.99.2` is the second
+release candidate for `4.0`.
+
+The `PATCH` number increments freely within a stage. A bump in `MINOR`
+(e.g. `90` → `95`) always indicates a stage promotion in development phase.
+
+Any experimental version must have it's dedicated branch.
+
+---
+
+## 5. Development environment
+
+| --- | --- | --- |
+| Bash | 4.3 | Namerefs (`local -n`) required |
+| shellcheck | any recent | Run before every commit |
+| git | any | For contributing patches |
+| bats-core | 1.x | Optional — for running the test suite |
+
+Install shellcheck:
+
+```bash
+# Debian / Ubuntu
+apt-get install shellcheck
+
+# Fedora / RHEL
+dnf install ShellCheck
+
+# macOS
+brew install shellcheck
+```
+
+---
+
+## 6. Code style
+
+### General rules
+
+- **Bash only** — no external interpreters in core modules. Python or Perl is
+  acceptable for completely self-contained, optional utilities that have no
+  dependencies beyond a minimal Debian or CentOS installation.
+- **4-space indentation** — no tabs.
+- **`[[ … ]]`** for all conditionals — not `[ … ]`.
+- **`(( … ))`** for arithmetic — not `$(( … ))` in conditionals.
+- **`local`** for all function-internal variables — avoid polluting the
+  environment. Prefer upper case for global and lowercase for local.
+- **`printf`** instead of `echo` all the time.
+- **Never `eval`** — use namerefs (`local -n`), `${!varname}` indirection, or
+  `declare -g` instead.
+- **No hardcoded defaults** — wire every configurable value through
+  `${VAR:-default}` and document the key in `profile.conf` and `README.md §4`.
+
+### Function conventions
+
+- Public functions **must** be exported: `export -f funcname`.
+- Every public function **must** support `-h` / `--help` and print usage to
+  stdout, returning 0.
+- Use `getopt` (not `getopts`) for option parsing — it handles long options and
+  `--` correctly.
+- Follow existing error-return conventions: 0 = success, 1 = usage error,
+  2 = bad options, 3 = missing dependency, 4+ = runtime failure.
+- Prefix all local helper variables with a short unique prefix (e.g. `_taz_`)
+  to prevent collisions with caller-scope variables.
+
+### Module structure
+
+Every new module should follow this pattern:
+
+```bash
+#!/usr/bin/env bash
+# <copyright block identical to existing modules>
+
+load_conf "<module_name>"
+
+# --- functions ---
+
+export -f my_function
+
+# EOF
+```
+
+Add the `load_conf` call near the top after any variable declarations.
+
+---
+
+## 7. Configuration keys
+
+When adding a configurable default:
+
+1. Use `${MY_VAR:-hardcoded_default}` in the function body.
+2. Add a commented-out entry with a description to `profile.conf`.
+3. Document the key in the matching table in `README.md §4.2`.
+
+---
+
+## 8. Theming
+
+New theme files go in `profile.d/themes/` with a `.theme` extension.
+They are **parsed, not executed** — do not add shell logic.  
+See the existing themes and `README.md §4.4` for the allowed syntax.
+
+---
+
+## 9. Running shellcheck
+
+```bash
+shellcheck -x profile.sh profile.d/*.sh
+```
+
+All warnings must be resolved before a patch will be accepted. Accepted
+suppression directives (`# shellcheck disable=SCxxxx`) require an inline
+comment explaining why the suppression is necessary.
+
+---
+
+## 10. Submitting a contribution
+
+### Via Git (preferred)
+
+1. Contact the maintainer to obtain push access, or fork on the Gitea instance.
+2. Create a branch: `git checkout -b feature/my-feature`.
+3. Commit with a clear subject line: `module: short description (≤ 72 chars)`.
+4. Push and open a pull request against `master`.
+
+### Via patch
+
+If you do not have push access:
+
+```bash
+git format-patch origin/master
+```
+
+Send the resulting `.patch` file(s) to
+`fatalerrors <at> geoffray-levasseur <dot> org`.
+
+### Commit message format
+
+```
+module: imperative short description
+
+Optional longer explanation of what changed and why. Wrap at 72 characters.
+Reference issue numbers if applicable: closes #42.
+```
+
+---
+
+## 11. What will be rejected
+
+- Code requiring packages not in a minimal Debian or CentOS install, unless optionnal.
+- Use of `eval`, `source`-based config loading, or other code-injection vectors.
+- Changes that break Bash 4.3 compatibility.
+- Patches without a passing `shellcheck` run.
+- New functions without `--help` support.

-# Frequently Asked Questions
-
----
-
-## Installation & loading
-
-**Q: profile refuses to load and prints "This profile requires Bash 4.3 or higher."**
-
-Your system's default shell is an older Bash (common on macOS, which ships
-Bash 3.x for licensing reasons). Install a newer Bash:
-```bash
-# macOS
-brew install bash
-# then add /opt/homebrew/bin/bash to /etc/shells and chsh
-```
-Or point your terminal emulator at the newer binary explicitly.
-
----
-
-**Q: I sourced `profile.sh` but functions are not available in sub-shells or scripts.**
-
-All public functions are exported with `export -f`. They are available in
-child Bash processes, but **not** in POSIX `sh` sub-shells. Make sure your
-scripts start with `#!/usr/bin/env bash`.
-
----
-
-**Q: I set `PROFILE_PATH` but profile still can't find its modules.**
-
-`PROFILE_PATH` must be exported *before* you source `profile.sh`:
-```bash
-export PROFILE_PATH=/opt/profile
-source /opt/profile/profile.sh
-```
-If set after sourcing, `MYPATH` is already locked in and the variable has
-no effect.
-
----
-
-**Q: Can I load profile system-wide via `/etc/profile`?**
-
-It is not recommended. User `.bashrc` files frequently set variables that
-conflict with the aliases and locale functions defined here, leading to
-surprising behaviour. Per-user sourcing from `~/.bashrc` is the supported
-method.
-
----
-
-## Configuration
-
-**Q: I edited `profile.conf` but my changes have no effect.**
-
-`profile.conf` is parsed once per shell session at load time. Open a new
-terminal (or `exec bash`) to pick up the changes. There is no live-reload.
-
----
-
-**Q: How do I find out which configuration keys a module supports?**
-
-Every supported key is documented with a comment in `profile.conf`.
-See also `README.md §4.2` for a consolidated table.
-
----
-
-**Q: A key I set in `profile.conf` is being ignored.**
-
-Check that:
-1. The key is inside the correct `[section]` header.
-2. There is no leading space before the section name (`[section]` not
-   `[ section ]`).
-3. The key is not commented out (no leading `#`).
-4. The value contains no backticks or `$(…)` — these are stripped by the
-   parser as a security measure.
-
----
-
-## Prompt & theming
-
-**Q: How do I change the prompt theme?**
-
-Add to `profile.conf`:
-```ini
-[prompt]
-PROMPT_THEME = dark
-```
-Built-in names: `default`, `dark`, `light`, `solarized`, `solarized-light`,
-`monokai`, `monochrome`, `abyss`, `plasma`, `adwaita`.
-
----
-
-**Q: The solarized or solarized-light theme shows wrong colours.**
-
-Those themes use 24-bit / true-colour ANSI sequences (`\e[38;2;R;G;Bm`).
-Test your terminal:
-```bash
-printf '\e[38;2;38;139;210mTrue colour test\e[0m\n'
-```
-If you see a solid blue word your terminal supports true colour.  
-If you see garbage or plain text, switch to a 16-colour theme
-(`dark`, `default`, etc.) or upgrade your terminal emulator.
-
----
-
-**Q: I created a custom theme but `load_theme` emits "key not allowed" warnings.**
-
-Theme files are parsed, not executed. Only `PROMPT_COLOR_*` keys and the
-standard colour variable names from `disp.sh` (`Black`, `Blue`, `On_IBlack`,
-…) are accepted. Any other key — including custom variables — is rejected.
-See `README.md §4.4` for the full list of accepted keys and value forms.
-
----
-
-**Q: Can a theme file contain shell logic or `$(…)` command substitutions?**
-
-No, and intentionally so. Theme files are parsed line-by-line; shell
-constructs are never evaluated. This is a security boundary — a malicious
-theme file cannot execute code. Values must be a colour variable reference
-(`$Blue`) or a raw ANSI escape literal (`\e[0;34m`).
-
----
-
-## Functions
-
-**Q: `meteo` prints "No city specified" even though I set a default.**
-
-The key is `METEO_DEFAULT_CITY` (not `DEFAULT_CITY`), and it must be in the
-`[info]` section:
-```ini
-[info]
-METEO_DEFAULT_CITY = Paris
-```
-
----
-
-**Q: `dwl` fails with "no download tool found".**
-
-`dwl` requires one of `curl`, `wget`, or `fetch` to be installed.
-Install curl:
-```bash
-# Debian / Ubuntu
-apt-get install curl
-
-# Fedora / RHEL
-dnf install curl
-```
-Or set `DWL_PREFERRED_TOOL` in `[net]` to whichever tool you have.
-
----
-
-**Q: `pkgs` does not find packages I know are installed.**
-
-`pkgs` delegates to `dpkg -l` (Debian/Ubuntu) or `rpm -qa` (RHEL/Fedora).
-If your distribution uses a different package manager (pacman, apk, brew …)
-it is not yet supported. See `doc/todo.md` for the tracking issue.
-
----
-
-**Q: `profile_upgrade` says "no update available" but I know there is one.**
-
-`check_updates` compares the content of the remote `version` file against
-`$PROFVERSION`. If `UPDT_DEFAULT_BRANCH` in `[updates]` points to a different
-branch than your installation, the version files may not match. Check:
-```bash
-cat "$MYPATH/version"
-```
-and make sure `UPDT_DEFAULT_BRANCH` matches the branch you track.
-
----
-
-## Compatibility
-
-**Q: Some functions misbehave on macOS / Cygwin.**
-
-Both environments ship non-GNU userland utilities with different flags and
-behaviour. profile is primarily developed and tested on Linux (Debian and
-RHEL families). macOS and Cygwin bugs are low priority; patches that add
-compatibility without breaking Linux support are welcome.
-
----
-
-**Q: Can I use profile with ZSH?**
-
-Not officially. Blockers include `local -A` (ZSH requires `typeset -A`) and
-`local -n` namerefs. A compatibility layer is listed in `doc/todo.md` but
-has not been implemented yet.
-
----
-
-## Miscellaneous
-
-**Q: How do I completely disable profile for one session?**
-
-```bash
-PROFILE_DISABLED=1 bash --norc
-```
-Or simply open a shell without sourcing `~/.bashrc` (`bash --norc`).
-
----
-
-**Q: How do I report a bug?**
-
-Open an issue on the
-[Gitea tracker](https://git.geoffray-levasseur.org/fatalerrors/profile/issues)
-or send a mail to `fatalerrors <at> geoffray-levasseur <dot> org` with:
-- The exact command that triggered the bug
-- Your OS and Bash version (`bash --version`)
-- The module involved
-- Any relevant error output
+# Frequently Asked Questions
+
+---
+
+## Installation & loading
+
+**Q: How do I install profile automatically into my shell startup files?**
+
+Run the installer directly (no need to source first):
+
+```bash
+bash <installpath>/profile/profile.sh --install
+```
+
+This appends the required `source` line to both `~/.bashrc` and `~/.profile`.
+To target only one file:
+
+```bash
+bash <installpath>/profile/profile.sh --install --bashrc
+bash <installpath>/profile/profile.sh --install --profile
+```
+
+The operation is idempotent — running it again will not add a duplicate line.
+
+---
+
+**Q: I ran `profile.sh` directly and got a warning about sourcing.**
+
+profile.sh is designed to be *sourced*, not executed:
+
+```bash
+source <installpath>/profile/profile.sh
+```
+
+The only exception is `--install`, which must be passed to a direct execution
+(`bash profile.sh --install`) to set up the sourcing line automatically.
+
+---
+
+**Q: profile refuses to load and prints "This profile requires Bash 4.3 or higher."**
+
+Your system's default shell is an older Bash (common on macOS, which ships
+Bash 3.x for licensing reasons). Install a newer Bash:
+
+```bash
+# macOS
+brew install bash
+# then add /opt/homebrew/bin/bash to /etc/shells and chsh
+```
+
+Or point your terminal emulator at the newer binary explicitly.
+
+---
+
+**Q: I sourced `profile.sh` but functions are not available in sub-shells or scripts.**
+
+All public functions are exported with `export -f`. They are available in
+child Bash processes, but **not** in POSIX `sh` sub-shells. Make sure your
+scripts start with `#!/usr/bin/env bash`.
+
+---
+
+**Q: Can I use profile functions in scripts?**
+
+Yes. The supported way is to source `profile.sh` from a Bash script:
+
+```bash
+#!/usr/bin/env bash
+source /path/to/profile/profile.sh
+
+taz -p auto -f lz mydir
+```
+
+You can also source one module directly (for example
+`profile.d/compress.sh`) if you only need a subset of functions.
+
+When you source a module directly, profile configuration parsing/loading from
+`profile.sh` is skipped, so defaults from `profile.conf` are not applied unless
+your script loads them explicitly.
+
+`profile.sh` also detects whether the current shell is interactive. In
+non-interactive shells (typical script execution), interactive-only features
+are intentionally disabled: prompt setup, aliases, welcome/info messages, and
+startup update checks are not enabled.
+
+In all cases, avoid aliases in scripts. Use real commands/functions instead,
+because alias expansion is interactive-shell oriented and can be disabled or
+behave differently in non-interactive execution.
+
+---
+
+**Q: I set `PROFILE_PATH` but profile still can't find its modules.**
+
+`PROFILE_PATH` must be exported *before* you source `profile.sh`:
+
+```bash
+export PROFILE_PATH=/opt/profile
+source /opt/profile/profile.sh
+```
+
+If set after sourcing, `MYPATH` is already locked in and the variable has
+no effect.
+
+---
+
+**Q: Can I load profile system-wide via `/etc/profile`?**
+
+It is not recommended. User `.bashrc` files frequently set variables that
+conflict with the aliases and locale functions defined here, leading to
+surprising behaviour. Per-user sourcing from `~/.bashrc` is the supported
+method.
+
+---
+

+
+`profile.conf` is parsed once per shell session at load time. Open a new
+terminal (or `exec bash`) to pick up the changes. There is no live-reload.
+
+---
+
+**Q: How do I find out which configuration keys a module supports?**
+
+Every supported key is documented with a comment in `profile.conf`.
+See also `README.md §4.2` for a consolidated table.
+
+---
+
+**Q: A key I set in `profile.conf` is being ignored.**
+
+Check that:
+
+1. The key is inside the correct `[section]` header.
+2. There is no leading space before the section name (`[section]` not
+   `[ section ]`).
+3. The key is not commented out (no leading `#`).
+4. The value contains no backticks or `$(…)` — these are stripped by the
+   parser as a security measure.
+
+---
+
+**Q: How do I force or auto-detect the correct `TERM` value?**
+
+Set `TERM` in the `[system]` section of `profile.conf`:
+
+```ini
+[system]
+# Auto-detect best available terminfo entry at startup (default)
+#TERM=smart
+
+# Force a specific entry
+#TERM=xterm-256color
+```
+
+When `TERM` is absent or set to `smart`, `term_set` probes your terminal
+emulator's environment variables (`COLORTERM`, `TERM_PROGRAM`, `VTE_VERSION`,
+`WT_SESSION`, `TMUX`, `STY`) and then tests terminfo entries in preference
+order.  If you are experiencing display issues, run `term_set` interactively
+and check the result with `echo $TERM`.  See *Prompt & theming* below for
+symptoms caused by a wrong `TERM` value.
+
+---
+
+## Prompt & theming
+
+**Q: How do I change the prompt theme?**
+
+Add to `profile.conf`:
+
+```ini
+[prompt]
+PROMPT_THEME = dark
+```
+
+Built-in names: `default`, `dark`, `light`, `solarized`, `solarized-light`,
+`monokai`, `monochrome`, `abyss`, `plasma`, `adwaita`, but you can create your
+own theme.
+
+---
+
+**Q: The solarized or solarized-light theme shows wrong colours.**
+
+Those themes use 24-bit / true-colour ANSI sequences (`\e[38;2;R;G;Bm`).
+Test your terminal:
+
+```bash
+printf '\e[38;2;38;139;210mTrue colour test\e[0m\n'
+```
+
+If you see a solid blue word your terminal supports true colour.  
+If you see garbage or plain text, switch to a 16-colour theme
+(`dark`, `default`, etc.) or upgrade your terminal emulator.
+
+---
+
+**Q: My prompt colours are missing, wrong, or ANSI escape codes appear as raw text.**
+
+The most common cause is a `TERM` value that does not match what your terminal
+emulator actually supports — either it points to an entry that does not exist
+in the local `terminfo` database, or it under-describes the real capabilities
+(e.g. `TERM=xterm` when the emulator supports 256 colours).
+
+Diagnose with:
+
+```bash
+echo "TERM=$TERM"
+tput colors        # should print 256 (or higher) for a capable terminal
+infocmp | head -5  # verify the loaded terminfo entry looks sane
+```
+
+Common scenarios and fixes:
+
+| Symptom | Likely cause | Fix |
+| --- | --- | --- |
+| `tput: unknown terminal` | `TERM` value has no terminfo entry | Remove the forced value and let `TERM=smart` auto-detect |
+| Only 8 colours instead of 256 | `TERM=xterm` instead of `xterm-256color` | Set `TERM=smart` or force `xterm-256color` |
+| Colours correct in plain shell but wrong inside tmux | tmux overwrites `TERM` | Set `TERM=smart` — `term_set` picks `tmux-256color` |
+| Colours correct outside screen but wrong inside it | Same, for GNU screen | Set `TERM=smart` — `term_set` picks `screen-256color` |
+| Prompt renders correctly but `rain` / `matrix` shows garbage | Terminal doesn't support the ANSI codes implied by `TERM` | Match `TERM` to the real emulator capability |
+
+The recommended approach is to leave `TERM` unset (or set it to `smart`) in
+`profile.conf` and let `term_set` choose the best available entry automatically.
+Only force a specific value if auto-detection picks the wrong one.
+
+Theme files are parsed, not executed. Only `PROMPT_COLOR_*` keys and the
+standard colour variable names from `disp.sh` (`Black`, `Blue`, `On_IBlack`,
+…) are accepted. Any other key — including custom variables — is rejected.
+See `README.md §4.4` for the full list of accepted keys and value forms.
+
+---
+
+**Q: Can a theme file contain shell logic or `$(…)` command substitutions?**
+
+No, and intentionally so. Theme files are parsed line-by-line; shell
+constructs are never evaluated. This is a security boundary — a malicious
+theme file cannot execute code. Values must be a colour variable reference
+(`$Blue`) or a raw ANSI escape literal (`\e[0;34m`).
+
+---
+
+## Git helpers
+
+**Q: What git helper functions does profile provide?**
+
+All git helpers are defined in `profile.d/git.sh` (new in 4.1.0):
+
+| Command | Purpose |
+| --- | --- |
+| `gst` | Compact status with branch tracking info |
+| `ggraph` | Decorated history graph |
+| `gsync` | Fetch and rebase onto upstream |
+| `gacp` | Add, commit and push in one command |
+| `greset` | Reset to upstream, stashing local changes first |
+| `gwip` | Quick WIP checkpoint commit |
+| `gprune` | Delete merged local branches |
+| `groot` | Print or cd to repository root |
+
+All commands accept `-h` / `--help`.
+
+---
+
+**Q: Tab completion for `gacp` does not show modified files.**
+
+Profile ships dedicated completions in `profile.d/bash-completion/git-completion.sh`,
+loaded automatically in interactive sessions. If completions are missing,
+check that the system git completion is installed:
+
+```bash
+# Debian / Ubuntu
+apt-get install bash-completion
+# Fedora / RHEL
+dnf install bash-completion
+```
+
+When the native git completion helpers are available, `gacp` path completion
+behaves exactly like `git add` (modified files, untracked files, directories).
+
+---
+
+**Q: `gacp` says "No files specified" even though I passed `-a`.**
+
+The `-a` / `--auto` flag adds all modified files (equivalent to `git add -A`).
+The default depends on `GIT_GACP_AUTO_ADD` in `profile.conf`:
+
+```ini
+[git]
+GIT_GACP_AUTO_ADD = 1
+```
+
+Set to `1` to make `-a` the default.
+
+---
+
+## Functions
+
+**Q: `meteo` prints "No city specified" even though I set a default.**
+
+The key is `METEO_DEFAULT_CITY` (not `DEFAULT_CITY`), and it must be in the
+`[info]` section:
+
+```ini
+[info]
+METEO_DEFAULT_CITY = Paris
+```
+
+---
+
+**Q: `dwl` fails with "no download tool found".**
+
+`dwl` requires one of `curl`, `wget`, or `fetch` to be installed.
+Install curl:
+
+```bash
+# Debian / Ubuntu
+apt-get install curl
+
+# Fedora / RHEL
+dnf install curl
+```
+
+Or set `DWL_PREFERRED_TOOL` in `[net]` to whichever tool you have.
+
+---
+
+**Q: How do I limit how long `dwl` waits for a download?**
+
+Use the `-t` / `--timeout` option:
+
+```bash
+dwl -t 5 https://example.com/file.txt /tmp/file.txt
+```
+
+This sets a 5-second cap on both the connection and the overall transfer.
+The timeout is propagated to `curl` (`--max-time` + `--connect-timeout`),
+`wget` (`--timeout`), or `fetch` (`-T`) transparently.
+
+---
+
+**Q: The prompt takes a long time to appear when my network is unavailable.**
+
+Fixed in 4.1.0. `check_updates -q` (called at startup) now enforces a
+3-second network timeout. If the update server is unreachable the check
+fails silently and the prompt appears immediately.
+
+---
+
+**Q: `help` only shows a list of functions. Can I get usage for a specific one?**
+
+Yes — pass the command name as an argument:
+
+```bash
+help gacp
+help dwl
+help taz
+```
+
+This calls `<command> --help` and prints the full usage for that function.
+
+---
+
+**Q: `pkgs` does not find packages I know are installed.**
+
+`pkgs` uses `get_pkgmgr` to detect the active package manager and delegates
+to the appropriate tool. Supported families: `apt` (Debian/Ubuntu),
+`dnf` / `yum` (RHEL/Fedora), `zypper` (openSUSE), `pacman` (Arch),
+`apk` (Alpine), `portage` (Gentoo), `xbps` (Void), `nix`, `brew` (macOS).
+If your distribution is not detected, run `get_pkgmgr` to see what is
+identified, and check that the package manager binary is in your `PATH`.
+
+---
+
+**Q: `profile_upgrade` says "no update available" but I know there is one.**
+
+`check_updates` compares the content of the remote `version` file against
+`$PROFVERSION`. If `UPDT_DEFAULT_BRANCH` in `[updates]` points to a different
+branch than your installation, the version files may not match. Check:
+
+```bash
+cat "$MYPATH/version"
+```
+
+and make sure `UPDT_DEFAULT_BRANCH` matches the branch you track.
+
+---
+
+## Compatibility
+
+**Q: Some functions misbehave on macOS / Cygwin.**
+
+Both environments ship non-GNU userland utilities with different flags and
+behaviour. profile is primarily developed and tested on Linux (Debian and
+RHEL families). macOS and Cygwin bugs are low priority; patches that add
+compatibility without breaking Linux support are welcome.
+
+---
+
+**Q: Can I use profile with ZSH?**
+
+Not officially. Blockers include `local -A` (ZSH requires `typeset -A`) and
+`local -n` namerefs. A compatibility layer is listed in `doc/todo.md` but
+has not been implemented yet.
+
+---
+
+## Miscellaneous
+
+**Q: How do I completely disable profile for one session?**
+
+```bash
+PROFILE_DISABLED=1 bash --norc
+```

+# Known bugs
+
+This document tracks currently known issues and limitations.
+
+## Open issues
+
+- None :-)
+
+---
+
+## Won't fix
+
+These issues are caused by platform or environment limitations outside the scope of this
+project and will not be addressed in Bash.
+
+### Prompt execution time is inaccurate in Windows Terminal (WSL)
+
+- **Description:** In Windows Terminal the displayed duration includes idle and typing time,
+  and is consistently higher than actual command execution time. In a native Linux terminal
+  (including WSL shells inside Konsole, QTerminal, etc.) timing correctly starts on Enter and
+  stops when the prompt reappears; in Windows Terminal, timer events appear tied to prompt
+  display rather than to the Enter keypress.
+- **Cause:** Execution time is measured via a `DEBUG` trap and `PROMPT_COMMAND` using
+  `date +%s%N` deltas. WSL + Windows Terminal introduces scheduling jitter between Bash signal
+  events and the underlying Windows terminal layer that does not match wall-clock perception.
+- **Impact:** Cosmetic / observability only — commands execute normally.
+- **Status:** Not fixable in Bash; this is a limitation of the Windows Terminal / WSL
+  integration layer.
+- **Workarounds:**
+  - Use a native Linux terminal under WSL (Konsole, QTerminal, Terminator, etc.) to
+    recover the expected Enter→prompt timing behavior.
+  - Use `/usr/bin/time -p <command>` or the shell built-in `time` when accurate timing
+    is required.
+  - Treat prompt timing as an inacurate indicator in this environment.
+
+### Rain/Matrix rendering is slow on Windows
+
+- **Description:** The rain, matrix and rainbow terminal effects are significantly slower
+  on Windows, especially with high density settings on every terminal software.
+- **Cause:** This is due to the way Windows handles terminal display updates, which is
+  inherently less efficient than on Unix-like systems.
+- **Status:** Not fixable in Bash; this is a limitation of Windows terminal design.
+- **Workaround:** Lower the density parameter for better performance, or use a Unix-like
+  environment for optimal speed.

----
-
-## Shell / compatibility
-
-- [ ] **ZSH compatibility layer** — most functions work already; the remaining
-  blockers are `local -A` (no associative arrays in ZSH without `typeset -A`)
-  and `local -n` namerefs. A thin compatibility shim would open the project to
-  ZSH users. **[hard]**
-- [ ] **Bash completion** — add a `profile.d/completion/` directory and write
-  `_profile_upgrade`, `_taz`, `_utaz`, `_meteo`, etc. completions so that
-  `<Tab>` works on all public functions. **[medium]**
-- [ ] **`shellcheck` clean pass** — run `shellcheck -x profile.sh profile.d/*.sh`
-  and address every remaining warning (currently a handful of SC2034 and SC2086
-  items). Integrate as a pre-commit hook. **[easy]**
-
----
-
-## Prompt & theming
-
-- [ ] **Git branch in prompt** — show the current branch name (and dirty
-  indicator) in the PS1 bar when inside a Git repository. Should be
-  gated behind a `[prompt]` config key so it can be disabled. **[medium]**
-- [ ] **Virtual-env / conda indicator** — detect `$VIRTUAL_ENV` / `$CONDA_DEFAULT_ENV`
-  and display the name in the prompt bar. **[easy]**
-- [ ] **True-colour terminal auto-detection** — query `$COLORTERM` and
-  `$TERM` at load time; automatically fall back from a 24-bit theme to its
-  16-colour equivalent when the terminal does not support true colour. **[medium]**
-- [ ] **True-colour variants of other themes** — create `monokai-tc.theme`,
-  `abyss-tc.theme`, etc. using the same `\e[38;2;R;G;Bm` approach as the
-  Solarized themes. **[easy]** _(per theme)_
-- [ ] **Theme preview command** — add a `theme_preview` (or `profile_theme`)
-  function that renders a colour swatch and a sample prompt line for the
-  currently loaded theme, so users can evaluate themes without reloading
-  the session. **[medium]**
-- [ ] **`load_theme` — DEFAULTCOL rebuild** — after overriding `DEFAULTFG` and
-  `DEFAULTBG`, automatically recompute `DEFAULTCOL` from the new values instead
-  of requiring the theme file to set it explicitly. **[easy]**
-
----
-
-## Module improvements
-
-### compress
-- [ ] **`taz` progress bar** — show a `pv` / `dd`-based progress indicator when
-  compressing large trees, gated behind a `-p` flag. **[medium]**
-- [ ] **`utaz` integrity check** — run `tar -tOf` / `unzip -t` / `7z t` before
-  extracting and abort if the archive is corrupt. **[easy]**
-
-### filefct
-- [ ] **`findbig` / `findzero` / `finddead` — `fd` integration** — optionally
-  use `fd` instead of `find` when available for faster traversal. **[easy]**
-- [ ] **`file_stats` — human-readable totals** — add `--human` flag to emit
-  sizes in K/M/G instead of bytes. **[easy]**
-
-### info
-- [ ] **`showinfo` fallback** — when neither `neofetch` nor `fastfetch` is
-  installed, print a minimal sysinfo block (hostname, OS, kernel, uptime,
-  CPU, RAM) using pure Bash + `/proc`. **[medium]**
-
-### net
-- [ ] **`dwl` resume support** — pass `-C -` to curl / `--continue-at -` to
-  wget for interrupted downloads; gate behind a `-r` flag. **[easy]**
-- [ ] **`myextip` multiple providers** — fall back to a secondary URL
-  (configurable via `MYEXTIP_FALLBACK_URL`) when the primary times out.
-  **[easy]**
-
-### packages
-- [ ] **Additional backends** — add support for `pacman` (Arch), `apk` (Alpine),
-  `xbps-query` (Void), and `brew` (macOS). **[medium]**
-
-### processes
-- [ ] **`ku` dry-run flag** — add `-n` / `--dry-run` to print what would be
-  killed without acting. **[easy]**
-
-### pwd
-- [ ] **`genpwd` passphrase mode** — add `-w` / `--words N` to generate
-  word-based passphrases (diceware-style) from `/usr/share/dict/words`.
-  **[medium]**
-
-### ssh
-- [ ] **SSH agent management** — add `ssh_agent_start` / `ssh_agent_stop` helpers
-  that start a persistent `ssh-agent`, add configured keys, and survive
-  re-login via a socket stored in `~/.ssh/agent.env`. **[medium]**
-- [ ] **`rmhost` glob support** — allow `rmhost '*.example.com'` to remove all
-  matching entries in one call. **[easy]**
-
-### updates
-- [ ] **Automatic update check age** — store a timestamp in `~/.cache/profile_last_check`;
-  skip the network request in `check_updates -q` if the last check was less
-  than `UPDT_CHECK_INTERVAL` hours ago (configurable, default 24). **[medium]**
-- [ ] **Changelog display** — after a successful `profile_upgrade`, fetch and
-  display `CHANGELOG.md` entries newer than the previously installed version.
-  **[medium]**
-
----
-
-## Infrastructure
-
-- [ ] **Test suite** — add a `test/` directory with `bats` (Bash Automated
-  Testing System) unit tests for pure functions (`expandlist`, `genpwd`,
-  `pwdscore`, `isipv4`, `isipv6`, `parse_conf`, `load_theme`, …). Target for
-  CI. **[hard]**
-- [ ] **CI pipeline** — Gitea Actions (or similar) job that runs `shellcheck`
-  and the `bats` suite on every push. **[medium]**
-- [ ] **`profile_status` function** — print a diagnostic summary: installed
-  version, active theme, loaded modules, detected Bash version, interactive /
-  login shell flags, and `profile.conf` path. **[easy]**
-- [ ] **`profile_uninstall` function** — remove the `source` line from
-  `~/.bashrc` / `~/.profile` and optionally delete the install directory,
-  with a dry-run mode. **[medium]**
-- [ ] **`disp` syslog integration** — add a `DISP_SYSLOG=1` config key that
-  additionally pipes E/W messages to `logger`. **[easy]**
