pi-devbox/Dockerfile.base

# pi-devbox — base image (variant-independent layers)
#
# This Dockerfile produces an image tagged base-<hash>, used as the parent
# for all published variants of pi-devbox. It contains everything that does
# not depend on variant-specific build-args (the pi install moves to
# Dockerfile.variant).
#
# The base is rebuilt only when this file or anything it COPYs in changes
# (rootfs/, entrypoint*.sh). Version bumps to PI_VERSION etc. do NOT
# trigger a base rebuild.
#
# To force a base rebuild for fresh apt packages without other code
# changes, bump the BASE_REBUILD_DATE comment below. The hash is
# content-addressed over this file, so any byte change invalidates the
# cache. Recommended cadence: once per release for security updates.
#
# BASE_REBUILD_DATE: 2026-07-13 (Unreleased — agent-browser CLI + Playwright Chromium for headless browser automation; prior: typst PDF engine + xz-utils + pandoc typst-template default-font patch)
#
# ── Lineage note ─────────────────────────────────────────────────────
# Adapted from opencode-devbox/Dockerfile.base (commit before v1.16.2).
# pi-devbox was previously a thin re-brand of opencode-devbox's pi-only
# variant; this file is the start of an independent build chain. The
# opencode-devbox install logic (INSTALL_OPENCODE, INSTALL_OMOS) does
# not appear here. The base is otherwise broadly equivalent so generic
# upstream improvements (CVE updates, new dev tooling) can be cherry-
# picked between repos.

# ── Core system packages ─────────────────────────────────────────────
# apt-get upgrade picks up any security/CVE fixes published between
# debian:trixie-slim base-image rebuilds. Paired with the index update
# and the install in the same layer so we don't bloat image history.
#
# Additions vs the upstream opencode-devbox base (2026-06-09):
#   pandoc       — Markdown↔HTML/PDF/etc. conversion. Required by pi-studio
#                  preview/export pipelines and broadly useful for any
#                  agent-driven document workflow. ~200 MB. NOTE: pandoc is
#                  only the front-end — PDF output needs a back-end engine.
#                  We ship `typst` (installed further down) as the
#                  lightweight default engine (`pandoc --pdf-engine=typst`)
#                  instead of a ~600 MB TeX Live install.
#   xz-utils     — `xz` decompressor. tar shells out to it for `.tar.xz`
#                  assets (typst ships .tar.xz). ~0.5 MB. Also generally
#                  useful for extracting xz-compressed archives.
#   graphviz     — `dot` rendering for many diagram tools. ~10 MB.
#                  See the bundled `dot-watch` helper for live .dot -> PNG
#                  re-render (handy with pi-studio's image preview).
#   imagemagick  — image conversion / resizing for thumbnails, etc. ~50 MB.
#   (yq is NOT apt-installed: Debian's `yq` is the unrelated Python tool;
#    mikefarah's Go yq is installed as a pinned binary further down.)
#   socat        — TCP relay. Powers `studio-expose`, which bridges
#                  pi-studio's container-loopback server to the container's
#                  external interface so a published port can reach it.
#                  ~1 MB; generally useful for any port-forwarding need.
#   nano         — small, non-modal terminal editor for users who don't want
#                  a vi-based editor. ~2.8 MB installed; its deps (libc6,
#                  libncursesw6, libtinfo6) are already pulled in by nvim/less/
#                  htop/tmux, so it adds no extra packages. Companion to nvim
#                  and the `micro` binary installed further down. EDITOR stays
#                  nvim; users opt in via `export EDITOR=nano`.
#   kitty-terminfo — terminfo entry for the kitty terminal (TERM=xterm-kitty).
#                  ~77 KB, terminfo file only (no kitty binary). Without it,
#                  ncurses apps fall back and Neovim can't reliably detect
#                  true-colour from kitty over ssh; installing it makes
#                  TERM=xterm-kitty understood. Pairs with the system-wide
#                  Neovim termguicolors default (etc/xdg/nvim/sysinit.vim).
#   ncurses-term   — broad terminfo bundle (wezterm, alacritty, foot, st, the
#                  base `ghostty` entry, and many more) so SSHing in from a
#                  modern emulator resolves its TERM instead of degrading to a
#                  dumb fallback. xterm-kitty is NOT in it (hence kitty-terminfo
#                  above); TERM=xterm-ghostty is compiled from an alias further
#                  down (ncurses ships `ghostty`, not `xterm-ghostty`). iTerm2
#                  defaults to xterm-256color (ncurses-base), so needs nothing.

# ── tmux defaults: 0-indexed windows and panes ───────────────────────
# pi-studio (omaclaren/pi-studio) hard-codes its tmux send target to
# `<session>:0.0`. Containers that ship tmux with default options are
# already 0-indexed; this file makes the assumption explicit so future
# /etc/tmux.conf consumers can read it. Users can override per-user
# in ~/.tmux.conf if they want 1-indexing — pi-studio will then fail
# to find its REPL session.

# ── SSH client defaults: ControlMaster on a writable socket path ──────
# Why this exists: the devbox typically mounts ~/.ssh from the host as
# read-only (security: keys are readable, but agents can't tamper with
# config / known_hosts / authorized_keys / plant a malicious ProxyCommand).
# OpenSSH's default ControlPath is ~/.ssh/cm/... which is unwritable on
# such mounts, so any attempt to use ControlMaster fails. Symptoms:
#   unix_listener: cannot bind to path /home/.../.ssh/cm/...: Read-only file system
#   kex_exchange_identification: Connection closed by remote host
# The latter manifests downstream of CGNAT per-destination flow caps
# (~4 concurrent flows on most European residential ISPs) which silently
# drop further SYNs once exceeded — making fresh ssh attempts fail with
# banner-exchange timeouts that look like a remote problem.
#
# Fix: set a system-wide default ControlPath in /tmp (per-container,
# tmpfs-friendly, always writable) so multiplexing Just Works without
# touching the read-only ~/.ssh mount. Per-host overrides in user's
# ~/.ssh/config still win — Debian's default /etc/ssh/ssh_config has
# `Include /etc/ssh/ssh_config.d/*.conf` *before* the `Host *` block,
# so user config can override these defaults if desired.
#
# CAVEAT (and why it is handled elsewhere): a user per-host override that
# points ControlPath BACK under the read-only ~/.ssh (e.g. the common CGNAT
# idiom `ControlPath ~/.ssh/cm/%r@%h:%p`) re-introduces the unwritable-socket
# failure — a system drop-in here can never override a user's per-host value.
# For `pi --ssh`, the ssh-controlmaster extension handles this by detecting an
# unwritable system ControlPath and falling back to its own /tmp master; for
# `ssh -F ~/.ssh-local/config` (dssh/dscp), setup-lan-access.sh redirects
# ControlPath into the writable ~/.ssh-local. See CHANGELOG "Unreleased".
#
# ControlPersist=10m means the master socket sticks around 10 min after
# the last session closes, so consecutive ssh calls in a workflow reuse
# the same TCP flow. Companion entrypoint-user.sh creates /tmp/sshcm
# (mode 700) on each container start.

# ── MemPalace — local-first AI memory system ─────────────────────────
# Provides semantic search over conversation history via 29 MCP tools.

# time to shave ~300 MB.
#
# Stall protection (fixed 2026-06-13; self-heal added 2026-06-25):
# mempalace-mcp is launched by the `mempalace.ts` pi extension from
# mempalace-toolkit (cloned below). That extension applies a per-REQUEST
# timeout in its JSON-RPC client and kills the child on stall, so a virtiofs
# cold-open of chroma.sqlite3 / HNSW load can no longer hang the pi TUI
# uninterruptibly. A stall-kill is no longer a permanent latch either: the
# next tool call respawns the server with capped exponential backoff (the
# budget resets on any successful response). Tunables:
# MEMPALACE_MCP_TIMEOUT_MS (default 60000), MEMPALACE_MCP_INIT_TIMEOUT_MS
# (default 300000 — generous so a genuine first cold-open isn't killed),
# MEMPALACE_MCP_MAX_RESPAWNS (default 2; 0 disables self-heal),
# MEMPALACE_MCP_RESPAWN_BACKOFF_MS (default 1000); timeouts of 0 disable.
# Defaults live in the extension, so no ENV is needed here. A standalone
# stdio-watchdog shim is NOT needed — the extension already owns
# request/response correlation. See CHANGELOG.md "Unreleased > Fixed".
ARG INSTALL_MEMPALACE=true
# Pin to a known-good version. Bump deliberately, not implicitly: an
# unpinned install silently swept in mempalace 3.3.x/3.4.0 with a broken
# diary_write schema. Pinning makes mempalace upgrades a reviewable diff
# rather than a surprise.
#
# 3.5.0 (2026-06) shipped the upstream fix for the top-level-anyOf diary_write
# schema (issue #1728 / PR #1717, merged 2026-06-14): the advertised schema
# is now `"required": ["agent_name"]` with entry/content enforced at dispatch,
# which Anthropic's tools API accepts — so the old mcp_server.py perl
# workaround that used to live below is gone.
#
# 3.6.0 (2026-07-17, PyPI latest) is additive/reliability only — secure
# `mempalace serve` remote mode, optional Milvus backend, atomic KG
# supersede(), conversation chronology, mining exclusions, plus recovery and
# locking fixes. Reviewed for MCP tool-schema changes before bumping (that
# being the exact regression class this pin exists to catch): there are NONE,
# and nothing touches diary_write. Two fixes matter for how this image uses
# mempalace: read-only mode now covers checkpoint + delete_by_source in
# _MUTATING_TOOLS (#1930), and agent attribution is preserved in
# mempalace_checkpoint (#2023/#2034).
#
# Keep in lockstep with opencode-devbox when bumping.
#
# 3.7.1 (from 3.6.0) is safe for anyone with an EXISTING LOCAL palace: verified
# against the 3.7.1 source, not the changelog. Legacy drawers lack the new
# `chunk_total` marker and both decision sites trust them ("trust the match as
# before"), NORMALIZE_VERSION is 2 in both, chromadb stays <2 (no index-format

# ── agent-browser — headless browser automation for the agent ────────
# Gives the agent a real browser it can drive (open/click/fill/eval/
# screenshot) so front-end work involving live DOM or WebGL can be VERIFIED
# rather than guessed at. The `agent-browser` skill (shipped from the
# skillset repo, not this image) documents the CLI; without this block that
# skill is a no-op because the binary isn't present. Verified end-to-end
# 2026-07-13: drives the baked Chromium headless (open + screenshot + eval
# into a WebGL SPA) — doctor's launch test passes in ~0.5s.
#
# TWO pieces, because agent-browser is a standalone Rust CLI that ships NO
# browser of its own — it only drives one you provide:
#   1. the CLI itself (npm; ~70 MB of prebuilt native binaries), and
#   2. a Chromium, which we fetch via Playwright.
#
# Why Playwright fetches the browser (and NOT `agent-browser install`):
# agent-browser's own installer drops Chrome under ~/.agent-browser/browsers
# — inside /home/${USER_NAME}, which is a NAMED VOLUME at runtime, so a
# build-time download would be SHADOWED (invisible) once the volume mounts.
# Playwright honours PLAYWRIGHT_BROWSERS_PATH, so we place the browser under
# /usr/local/share (never shadowed) and hand agent-browser a STABLE symlink
# via AGENT_BROWSER_EXECUTABLE_PATH — the symlink insulates the ENV from
# Playwright's per-version, per-ARCH browser directory (`chrome-linux` on arm64,
# `chrome-linux64` on amd64 — Chrome-for-Testing), so we `find` the `chrome`
# binary rather than hardcode the path; the headless-shell binary is named
# `chrome-headless-shell`, so `-name chrome` skips it.
#
# `playwright install --with-deps chromium` also apt-installs Chromium's
# runtime libs; verified to resolve correctly on Debian trixie (exit 0 — the
# t64 library renames are handled by Playwright's dep list). Build runs as
# root, so the apt step works. NPM_CONFIG_PREFIX=/usr keeps both CLIs on /usr
# so they survive the ~/.pi/npm-global volume mount (same trick the variant
# uses for pi). After fetching, we DROP Playwright's `chromium_headless_shell-*`
# build — agent-browser drives the full chrome (verified, incl. headless), so the
# headless shell is dead weight — and clean the apt/npm caches, trimming the
# layer to ~625 MB (Chromium) from ~960 MB. Still the bulk of the base's size,
# and the one real tradeoff of shipping this to every variant.

# ── typst — lightweight PDF engine for pandoc (Markdown→PDF) ─────────
# pandoc (apt-installed above) is only a front-end; rendering PDF needs a
# back-end engine. Rather than a ~600 MB TeX Live install, we ship typst:
# a single ~30 MB static Rust binary with no LaTeX dependency. pi-studio's
# PDF export (studio_export_pdf) and pandoc invocations use it via
# `pandoc --pdf-engine=typst`. A fuller TeX Live remains the higher-
# fidelity fallback for anyone who needs LaTeX-exact output (not shipped
# here — install on demand or in a future variant).
#
# Follows the `latest` GitHub-release convention (like tealdeer/uv/bat).
# typst ships a `.tar.xz` asset (hence xz-utils in the apt layer above)
# that extracts to typst-<arch>-unknown-linux-musl/typst. Pin a specific
# tag with --build-arg TYPST_VERSION=vX.Y.Z.
#
# We also patch pandoc's bundled typst template
# (/usr/share/pandoc/data/templates/template.typst): its conf() defaults the
# document font to an empty tuple (`font: ()`), so a naked
# `pandoc --pdf-engine=typst` fails with "font fallback list must not be empty"
# unless the caller passes `-V mainfont=...`. We default it to Libertinus Serif
# (typst's own bundled default font) so PDF export works out-of-the-box.
