# bare-os-holesail Skill

## When to use

Use when the user asks about **Holesail** in this repo: exposing TCP/UDP through Holepunch-style tunnels, **`/bin/holesail`** CLI, **`bare-holesail`** initd, **`BARE_OS_HOLESAIL_*`** environment variables, **`ctx.bare.holesail`** from drive bundles, **`~/.holesail/state.json`** persistence (**`seed`** / **`key`**), or licensing (**upstream `holesail` is AGPL-3.0**).

## Mental model

1. **Integration** lives in **`packages/bare-os-booter/lib/bare-holesail.js`** (initd + optional early “kernel-path” instance), **`bare-holesail-managed.js`** ( **`state.json`** rows, **`ensure`**, **`SyncPersistedServerKey`** ), **`holesail-cli.js`** (**`ctx.bareOsRunHolesailCli`** for **`/bin/holesail`**), **`bare-os-www-holesail.js`**, **`bare-os-ssh-holesail.js`**.
2. **Resolution order** under **`pear run`**: the booter prefers **`ctx.bare.holesail`** ( **`/lib/bare/bundles/holesail.js`** after drive merge), else host **`import.meta.resolve('holesail')`**, else eval of the drive IIFE bundle via **`ctx.vfs`** — **`/bin`** and **`/boot/init.js`** are **not** Node modules, so scripts must not **`require('holesail')`**.
3. **Stock default**: initd unit **`bare-holesail`** is **on** when **`BARE_OS_HOLESAIL_INITD`** and **`BARE_OS_HOLESAIL_MANAGED`** are left at defaults (**`1`** in stock **`shellEnv`** unless the host clears them). Disable with **`BARE_OS_HOLESAIL_INITD=0`** or **`systemctl disable bare-holesail`** (**`~/.config/bare-os/initd/disabled.txt`**).
4. **Stock auto-rows** — **`bare-www-<port>`** after **`bare-os-www`** listens (**`BARE_OS_WWW_HOLESAIL=0`** disables merge). **`bare-ssh-<port>`** after **`bare-openssh`** listens (**`BARE_OS_SSH_HOLESAIL=0`** disables). **`bare-user-session-stack`** re-ensures SSH tunnel after **`bare-holesail`** starts if sshd was already listening.

## Managed state (`state.json`)

- **Default path** — **`BARE_OS_HOLESAIL_STATE`** unset → **`~/.holesail/state.json`** (logical, under **`$HOME`**). Override env for a different logical path.
- **Legacy merge** — If the primary file is empty/missing: **`/.bare/holesail/state.json`**, **`/.bare/holesail/guest/state.json`**, **`/home/guest/.holesail/state.json`** are merged once.
- **`seed`** — Stable ctor secret: **64-char hex**, or valid **z32** suffix (migrated from legacy **`hs://…`**-only rows). Never replace **`seed`** with only the URL suffix written as ctor input.
- **`key`** — Full shareable **`hs://…`** URL; written/updated after **`ready()`** (**`bareHolesailManagedSyncPersistedServerKey`**). **`holesail list`** shows live URL when tunnel runs.
- **Daemon** — First **`startManagedConnectionsFromDisk`** pass starts all rows; **yield** one tick; **second pass** uses **`onlyNew`** so **`bare-os-www`** / **`bare-openssh`** can append rows without tearing down tunnels already started.

## Managed vs single-tunnel mode

- **Managed (default)** — **`BARE_OS_HOLESAIL_MANAGED=1`**. Operator CLI: **`holesail list`**, **`add`**, **`remove`**, **`start`**, **`stop`**, **`restart`**, **`enable`**, **`disable`**, **`path`**, **`help`**.
- **Single tunnel** — **`BARE_OS_HOLESAIL_MANAGED=0`**, then exactly one of **`BARE_OS_HOLESAIL_SERVER=1`** or **`BARE_OS_HOLESAIL_CLIENT=1`**, and in client mode **`BARE_OS_HOLESAIL_KEY=…`**. Optional: **`BARE_OS_HOLESAIL_SECURE`**, **`PORT`**, **`HOST`**, **`UDP`**, **`LOG`**.

## Early booter (“kernel-path”) instance

Separate from initd: enable with **`BARE_OS_HOLESAIL_KERNEL=1`** and the **`BARE_OS_HOLESAIL_KERNEL_*`** mirror env vars. Starts after the **`repl`** boot phase and before **`startBareInitd`**; teardown uses **`registerKernelShutdownHook`**. `**hs.pause()` / `hs.resume()`** tie into mobile suspend/resume.

## Operator CLI quick reference

From **`holesail-cli.js`** help text:

- **`holesail add ID --server|--client`** with optional **`--key`**, bare **`hs://…`** token (no **`--key`** prefix), **`--port`**, **`--host`**, **`--udp`**, `**--secure` / `--no-secure**`, **`--log`**.
- **`holesail remove ID`**, **`start|stop|restart ID`**, **`enable|disable ID`**.

Managed **`bare-holesail`** starts after **`kernel-logger`** and **`bare-os-www`** by default. Logs: **`/var/log/bare-os/holesail.log`**. Example unit drop-in: **`/etc/bare-os/units/bare-holesail.unit.example`**.

## Debugging and safety

- **`BARE_OS_HOLESAIL_DEBUG=1`** — extra console lines (**URLs only**; keys are not logged in full).
- Do **not** paste full connection secrets into chat or commit logs; redact **`hs://`** payloads when summarizing.
- **`read_man_page holesail`** (after a coreutils/man build); **`handbook/04-the-booter-runtime.md`** § **bare-holesail**, § **bare-os-www**, § **bare-openssh** — prose source of truth.

## Execution steps (for the agent)

1. Confirm whether the question is **operator tunnels** (CLI + state file + initd) vs **guest scripting** (**`ctx.bare.holesail`**).
2. If live behavior matters, prefer **`read_proc_file`** / initd journal paths the user can access over guessing from docs.
3. Mention **AGPL** when the user plans to redistribute or ship a product that bundles **`holesail`**.

## Constraints

- Read-only unless the user explicitly authorizes changing env, initd disables, or **`holesail add`** state.
- Do not assume **`holesail`** is **`import()`**-able from **`pear:`** without **`ctx.bare`** or the drive bundle.
