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, after an unpinned install once
swept in the broken 3.3.x/3.4.0 diary_write schema. There are none, and
nothing touches diary_write, so the perl workaround removed in v1.2.2 stays
removed.
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) — the latter
because the diary protocol relies on per-agent attribution.
Also adds a CHANGELOG Unreleased block that backfills the per-variant image
description labels (1fd524e), pushed after the v1.6.4 tag without an entry.
Not tagged: more changes are queued for the next release. Pushing to main
triggers only lint.yml (actionlint + hadolint) — the image build/publish
workflow is tag-only. Verified clean against the CI-pinned hadolint 2.14.0.
v1.6.0's first build failed on amd64: playwright@latest fetches Chrome for
Testing, which extracts to chromium-<rev>/chrome-linux64/ on amd64 (vs
chrome-linux/ on arm64). The hardcoded chrome-linux/ glob matched only arm64,
so amd64 built no /usr/local/bin/agent-chrome symlink and 'test -x' failed
(agent-browser --version had already printed 0.32.1 — the tell).
Replace the glob with an arch-agnostic 'find -name chrome -path */chromium-*/*'
(skips the chrome-headless-shell binary and the chromium_headless_shell dir),
guarded by [ -n ] + the existing test -x. Verified locally: resolves the CfT
chrome and agent-browser drives it headless. hadolint clean.
Size concern ahead of the v1.6.0 base rebuild. agent-browser drives the full
chrome (verified headless: open/title/eval with the headless_shell removed), so
Playwright's chromium_headless_shell-* build is dead weight — drop it (~334MB),
and clean apt/npm caches in-layer. Net browser footprint ~625MB/arch.
CI disk is otherwise fine: build-base's 'Reclaim runner disk' step frees
~20-30GB (hostedtoolcache/dotnet/android/jvm) + docker prune before buildx.
hadolint clean.
Gives the agent a real browser it can drive so front-end work involving live
DOM/WebGL can be VERIFIED, not guessed. The agent-browser skill (from the
skillset repo) was a no-op without the binary; it now works out of the box.
- agent-browser CLI (standalone Rust, ships no browser) via npm, prefixed
NPM_CONFIG_PREFIX=/usr so it survives the ~/.pi/npm-global volume.
- Chromium fetched with 'playwright install --with-deps chromium' into
PLAYWRIGHT_BROWSERS_PATH=/usr/local/share/ms-playwright — a system path that
the /home/developer volume can't shadow (unlike agent-browser's own
~/.agent-browser/browsers default, which WOULD vanish on recreate).
- Stable /usr/local/bin/agent-chrome symlink, exported as
AGENT_BROWSER_EXECUTABLE_PATH, insulates the ENV from Playwright's
per-version chromium-<rev> dir name.
Verified end-to-end (this session): agent-browser drives the baked Chromium
headless (open + title + screenshot + eval into a WebGL SPA); doctor launch
test passes in ~0.5s. Debian trixie --with-deps resolution verified (exit 0;
t64 lib renames handled). hadolint clean; check-base-hash OK (only *_VERSION
args added). Cost ~960 MB (Chromium + headless shell). Base-affecting →
rebuilds base-<hash> on next release.
Wraps /etc/pi-devbox/build-manifest.json (already written at docker-build
time in Dockerfile.variant) into a human-readable summary instead of
requiring users to know the manifest path and pipe it through jq
themselves.
- rootfs/usr/local/bin/pi-devbox-version: human (default) / --json /
--quiet output modes. Also flags live drift — compares the baked
pi_version against the actually-running `pi --version` and warns
on mismatch rather than trusting the manifest blindly (same
ground-truth philosophy as the manifest generation itself). Exits 1
with a short stderr notice on images built before the manifest
existed, instead of failing silently.
- entrypoint-user.sh: calls it as the very first line. CMD is
`bash -l` with tty:true in compose, so this banner lands directly
above the first prompt on container start — no separate motd/bashrc
hook needed (deliberately not wired into .bash_aliases, which would
reprint on every docker exec -it).
- Dockerfile.base: COPY + chmod, same pattern as dot-watch/studio-expose.
- scripts/smoke-test.sh: 4 new checks (binary present+executable, human
output has release tag, --json round-trips the manifest, --quiet is
a single line).
- README.md / AGENTS.md / CHANGELOG.md updated.
The base only shipped ncurses-base (xterm-256color, tmux), so SSHing in from
WezTerm/Alacritty/foot/Ghostty degraded to a dumb TERM fallback. Following the
maintainer's ansible common role:
- Dockerfile.base: install ncurses-term (terminfo for wezterm, alacritty,
foot, st, base ghostty entry, and many more).
- rootfs/.../terminfo-src/ghostty.terminfo: thin xterm-ghostty alias
(use=ghostty) — Ghostty connects as TERM=xterm-ghostty, which no distro
packages. Compiled into the system db with 'tic -x'; build asserts it
resolved via infocmp.
- kitty (xterm-kitty) already covered by kitty-terminfo; iTerm2 uses
xterm-256color (ncurses-base).
- smoke-test: assert ncurses-term emulators + xterm-ghostty alias resolve.
Validated end-to-end in a throwaway container: ncurses-term brings the
entries, the alias compiles and equals the ghostty capability set. hadolint
clean, bash -n OK. Base-affecting, rebuilds base-<hash>. No tag.
Vanilla Neovim fell back to a 256-colour palette over ssh/kitty and rendered
strings/comments in a muddy, low-contrast colour. Fix, all base-affecting:
- rootfs/etc/xdg/nvim/sysinit.vim: system vimrc enabling termguicolors. Loads
for every user before any personal ~/.config/nvim; overridable per-user.
- Dockerfile.base: install kitty-terminfo (TERM=xterm-kitty understood; lets
Neovim auto-detect true colour) and set ENV COLORTERM=truecolor.
- smoke-test.sh: assert xterm-kitty terminfo present and nvim tgc default on.
- CHANGELOG (Unreleased/Added) + README editor note.
No tag — lands on the next base-<hash> rebuild.
pandoc's bundled typst template 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". Patch the template default to
Libertinus Serif (typst's own bundled default) at build time so PDF
export works out of the box. Document usage in README and note the fix
in CHANGELOG (Unreleased). Base-affecting.
pandoc has been in the base since v1.0.0 but only as a front-end; PDF
export (studio_export_pdf / pandoc -o out.pdf) failed with 'xelatex not
found' because no back-end engine was installed. Ship typst (~30 MB
static Rust binary, no LaTeX) as the default engine via
`pandoc --pdf-engine=typst`, chosen over a ~600 MB TeX Live install.
texlive-xetex remains the higher-fidelity install-on-demand fallback.
- Dockerfile.base: install typst (latest GitHub-release idiom, pin via
TYPST_VERSION); add xz-utils (typst ships .tar.xz); bump
BASE_REBUILD_DATE. Lands in base-<hash>.
- smoke-test.sh: verify typst + a real pandoc --pdf-engine=typst render.
- README/AGENTS/CHANGELOG: typst now shipped (supersedes the planned
:latest-studio-tex variant).
No tag pushed — CI build intentionally deferred.
The image shipped only nvim (EDITOR=nvim), a modal vi-style editor. Not
everyone is comfortable with vi keybindings, so add both a classic and a
modern non-modal option:
- nano (apt): ~2.8 MB installed; deps (libc6, libncursesw6, libtinfo6)
already present via nvim/less/htop/tmux, so no extra packages pulled in.
- micro: ~12 MB single static Go binary from GitHub releases (same pattern
as bat/eza/zoxide). Desktop-style keys (Ctrl+S/Ctrl+Q), mouse, syntax
highlighting. ARG MICRO_VERSION pins; defaults to latest.
Combined ~15 MB (<0.5% of the ~3.2 GB image). EDITOR stays nvim; both new
editors are opt-in (export EDITOR=micro | nano). Uses the canonical
micro-editor/micro URL because the old zyedidia/micro org rename makes
/releases/latest redirect to another /latest, defeating the tag-parsing
latest-resolution idiom.
Base-image change, so it lands on the next base-<hash> rebuild. Updates
README tool table + EDITOR note, CHANGELOG (Unreleased/Added), and
smoke-test.sh (nano + micro presence checks).
Seed ~/.gitignore_global from /etc/skel-devbox (seed-if-absent, like
.bash_aliases/.inputrc, so user edits survive recreate) and wire it via
git config --global core.excludesFile, guarded so a user-set excludesFile
is never overridden. Ignores *.bak, *.bak.*, *~, *.orig, *.swp, *.tmp
across all repos without per-repo .gitignore entries.
mempalace.ts now self-heals (respawn with capped backoff) instead of
latching unavailable, and the init-timeout default is 300000. Update the
explanatory comment + tunable list (MEMPALACE_MCP_MAX_RESPAWNS,
MEMPALACE_MCP_RESPAWN_BACKOFF_MS). Comment-only; no build/ENV change.
Match the repo's latest-following convention (tealdeer/uv/etc.) and keep the
container in sync with the Mac's brew yq. smoke-test now asserts mikefarah AND
major v4, so a surprise yq v5 fails CI instead of silently breaking
provision.sh. Pin still available via --build-arg YQ_VERSION=vX.Y.Z.
Debian/Ubuntu `apt install yq` is kislyuk/yq (Python, v3.x), incompatible
with the mikefarah v4 syntax the cloud-init repo's provision.sh/deploy.sh
require. Replace the apt package with a pinned mikefarah Go binary, mirroring
the existing tealdeer ARG (latest-or-pin) pattern, multi-arch amd64/arm64.
smoke-test.sh now asserts `yq --version` reports mikefarah so CI catches a
regression. CHANGELOG: Unreleased entry.
- Bump mempalace pin 3.4.0 -> 3.5.0: 3.5.0 carries the upstream fix for the
top-level-anyOf diary_write schema (issue #1728 / PR #1717, merged
2026-06-14). Verified against the published 3.5.0 wheel that mcp_server.py
now advertises 'required: [agent_name]' with no root-level anyOf.
- Remove the Dockerfile.base perl workaround that stripped the anyOf from the
installed mcp_server.py — obsolete now the fix is upstream.
- pi auto-resolves to npm latest (0.79.10 -> 0.80.2) at build.
- CHANGELOG v1.2.2.
Ship skills inside the image (independent of any mounted skillset repo):
- rootfs/usr/local/share/pi-devbox/skills/<name>/ symlinked into
~/.agents/skills/ by entrypoint-user.sh (foreign-link, survives volume
recreate, never clobbers a skillset/user skill of the same name).
- New pi-devbox-environment skill: persistence model, host/LAN SSH
reachability, split-DNS mechanisms, interactive-vs-tool-shell alias
gotcha, tmux 0-index, uv-first Python, pi-studio reachability. Agnostic
to host OS / hostnames / domains / nameservers (discovered at runtime).
- Dockerfile.variant appends pi-global-AGENTS.append.md onto pi-toolkit's
pi-global-AGENTS.md (single global slot) so the skill is loaded
proactively; gated on /usr/local/lib/pi-devbox/. Idempotent.
- smoke-test: baked-skill + append-snippet + merged-marker presence and a
runtime symlink assertion.
- docs: README 'Agent skills' section, AGENTS.md layout, DOCKER_HUB.md;
moved studio-tex roadmap to v1.3.0.
pi 0.79.7 -> 0.79.10 (auto-resolved from npm latest at build).
Adds OCI labels + /etc/pi-devbox/build-manifest.json so a published tag is
self-describing and reconstructable after CI logs rotate (manifest is
written from the actual checked-out HEAD of each /opt clone + live
pi --version, not just the intended build-args).
Hardens the build plumbing:
- scripts/check-base-hash.sh guards the base-rebuild invariant: every
floating ARG *_REF in Dockerfile.base must be folded into the base_tag
hash, else a ref-only change silently fails to rebuild the base
(v1.1.2-class staleness footgun). Runs in base-decide and locally.
- resolve-versions now fails loud instead of falling back to a floating
main/master on a transient API failure — validates each ref is a 40-hex
SHA (and pi a real semver) and aborts the release otherwise.
- The three gitea companions (pi-toolkit, pi-extensions, mempalace-toolkit)
gained overridable *_REPO build-args (defaulting to the canonical gitea
origin) so a relocated/forked build can repoint them without editing the
Dockerfiles — matching the existing PI_FORK_REPO/PI_OBSMEM_REPO pattern.
README documents the forked/relocated build-arg trick and how to read the
labels + manifest. smoke-test asserts the manifest + labels. pi bumps
0.79.7 → 0.79.8 (auto-resolved at build).
Coordinated with the pi-extensions ssh-controlmaster fix (picked up at build via
PI_EXTENSIONS_REF=main), this makes `pi --ssh <host>` and `dssh`/`dscp` robust
to a user ~/.ssh/config whose per-host ControlPath points under the read-only
~/.ssh bind-mount (e.g. `ControlPath ~/.ssh/cm/%r@%h:%p`). A system default can
never override a user's per-host value, so the fix lives in two layers.
- setup-lan-access.sh: always render the writable ~/.ssh-local/config sidecar
(Host * ControlPath redirect into ~/.ssh-local/cm + Include ~/.ssh/config) on
EVERY host OS. Previously the script exited early (no-op) on native Linux,
leaving dssh/dscp broken when ~/.ssh was read-only there too. The host-jump
block, its key generation, and the authorize hints stay gated on VM-backed
detection / DEVBOX_LAN_ACCESS=jump (new NEED_JUMP flag).
- Dockerfile.base: document that the /etc/ssh drop-in default cannot override a
user per-host ControlPath; cross-ref the two handling layers.
- entrypoint-user.sh: correct the now-stale "no-op on native Linux" comment.
- README.md / DOCKER_HUB.md: document read-only-~/.ssh ControlPath handling.
CHANGELOG: v1.1.5 (Fixed + Changed + pi 0.79.6 -> 0.79.7 auto-resolved bump).
Parity with opencode-devbox: PR #1735 (the diary_write root-anyOf fix) was
closed UNMERGED on 2026-06-11, so the old "remove once PR #1735 ships" TODO
pointed at a dead PR. Issue #1728 is still open; PR #1717 is the current live
candidate; mempalace PyPI latest is still 3.4.0 (== our pin), so the
workaround stays.
- Dockerfile.base: rewrite the upstream-tracking comment + TODO (#1735 dead,
watch #1717, removal trigger = a PyPI release > 3.4.0 stripping root anyOf).
- CHANGELOG: Unreleased Docs entry.
Docs-only; no behavior change.
mempalace-toolkit is the only companion cloned in Dockerfile.base (all
others live in Dockerfile.variant), so it bypassed the resolve-versions ->
build-arg plumbing and its ref stayed a literal `main`. Because the base
only rebuilds on a content hash of Dockerfile.base + rootfs/* + entrypoints,
a toolkit-only fix would silently fail to land unless Dockerfile.base itself
changed (as it incidentally did in v1.1.1).
Changes:
- resolve-versions: new mempalace_toolkit_ref output (gitea commits API,
mirrors pi-toolkit resolution; jq '.[0].sha // "main"' fallback).
- base-decide: needs resolve-versions; fold the resolved SHA into the
base-tag hash so a moved toolkit forces a base rebuild automatically.
- build-base: needs resolve-versions; pass --build-arg MEMPALACE_TOOLKIT_REF.
- Dockerfile.base: switch clone from `git clone --branch` to a SHA-capable
`git fetch <ref> + checkout FETCH_HEAD` (the --branch <SHA> footgun
already fixed in Dockerfile.variant, run 374).
base_tag now reflects a live gitea lookup; on API blip it falls back to
`main`, triggering one extra rebuild, never a missed one.
No new tag — lands on the next v* release or workflow_dispatch.
The per-request timeout + stall-kill landed in mempalace-toolkit's
mempalace.ts pi extension (commit a3b8829), which the base clones at
build via MEMPALACE_TOOLKIT_REF=main. A base rebuild picks it up.
- CHANGELOG: move from 'Known issues' to 'Fixed'; document the env knobs
(MEMPALACE_MCP_TIMEOUT_MS / MEMPALACE_MCP_INIT_TIMEOUT_MS) and why the
standalone stdio-watchdog shim was dropped.
- Dockerfile.base: replace the TODO with a note pointing at the fix.
Symptom: pi TUI blocks on a mempalace tool call, ESC does not abort.
Initial WAL-contention hypothesis ruled out (no other writer running).
Likely cause: virtiofs cold open of chroma.sqlite3 stalls the JSON-RPC
initialize handshake; pi has no per-call MCP timeout.
Recovery today: docker exec <ctr> pkill -9 -f mempalace-mcp, restart pi.
Planned fix (deferred until after opencode-devbox pi removal): stdio
watchdog shim with per-REQUEST timeout. A naive process-lifetime
timeout wrapper is wrong because mempalace-mcp is long-lived.
Sharing the palace across harnesses remains the goal.
pi-studio renders Mermaid natively but has no DOT renderer. Its markdown
preview displays local PNG/JPG/GIF/WEBP images, so dot-watch closes the
loop for Graphviz: edit .dot -> auto-render <name>.png -> Studio
refresh-from-disk shows the update. Uses mtime polling (no inotify dep).
- rootfs/usr/local/bin/dot-watch: the helper (executable)
- Dockerfile.base: COPY + chmod, following the studio-expose pattern
- README.md: 'Graphviz diagrams in Studio' subsection
- CHANGELOG.md: Unreleased entry
graphviz was already in the base image; no new package.
pi-studio binds the container's 127.0.0.1, which a published Docker port
can't reach. Add a robust, portable bridge rather than a doc-only one-liner:
- Dockerfile.base: add socat (~1 MB, generally useful TCP relay).
- rootfs/usr/local/bin/studio-expose: socat TCP relay listening on the
container's egress IPv4 (not 0.0.0.0 — that would EADDRINUSE against
Studio's loopback listener) forwarding to 127.0.0.1:PORT on the SAME
port, so Studio's printed token URL works verbatim. Robust egress-IP
detection (hostname -I, loopback-filtered; ip route get fallback),
--help, port validation, foreground.
- entrypoint-user.sh: opt-in STUDIO_EXPOSE=1 auto-starts the bridge in the
background (studio variant only). Default OFF — Studio stays loopback-only
(its secure default) unless explicitly opted in.
- README: 'Using pi-studio' now documents host-networking (A) and the
studio-expose/STUDIO_EXPOSE bridge (B) with a security note; ssh -L for
remote, mosh caveat retained.
- smoke-test: assert socat + studio-expose present (base-level).
- CHANGELOG/AGENTS updated.
No tag — stopping for review.
Anthropic's tools API rejects top-level anyOf/oneOf/allOf in
input_schema. Mempalace 3.3.x/3.4.0 advertise diary_write with
`anyOf: [{required:[entry]}, {required:[content]}]`, breaking pi
on first prompt with:
tools.<n>.custom.input_schema: input_schema does not support
oneOf, allOf, or anyOf at the top level
Patch the installed mcp_server.py after `uv tool install` to drop
the anyOf block and require ["agent_name", "entry"] instead. The
handler still accepts `content` server-side as a kwarg alias, so
callers using either name keep working.
The workaround is idempotent and self-deactivating: once upstream
ships the fix the regex no longer matches and the RUN is a silent
no-op.
Also pin mempalace to 3.4.0 via a new MEMPALACE_VERSION build arg
so future bumps are a deliberate, reviewable diff rather than an
implicit pull of latest (an implicit upgrade is what swept the
broken schema in unannounced).

Self-contained build chain — own Dockerfile.base + Dockerfile.variant
+ entrypoint scripts + rootfs + CI pipeline. Previously v0.79.0 and
earlier were thin re-brands of opencode-devbox's pi-only variant
(joakimp/pi-devbox:base-pi-only built by opencode-devbox CI).
Architectural changes:
- Replace 5-line Dockerfile shim with full base+variant pair.
- Adapt CI workflow from opencode-devbox/docker-publish-split.yml,
simplified to a single variant. Includes content-addressed base hash,
PI_VERSION concrete-resolution to defeat registry-buildcache footgun,
crane-based base-latest promotion, and the c6f9d11 smoke-test gate.
- pi-devbox releases no longer require rebuilding opencode-devbox first.
Base image additions:
- pandoc, graphviz, imagemagick, yq — broadly useful, ~260 MB total.
- tldr (tealdeer) — Rust port replaces Node tldr global, saves 135 MB.
- /etc/tmux.conf with base-index 0 + pane-base-index 0 — required for
the planned :latest-studio variant; pi-studio hard-codes :0.0 target.
Smoke test:
- New checks for pandoc, graphviz, imagemagick, yq, tldr, tmux config,
/tmp/sshcm directory.
- Image-size measurement now sums docker history layers (the prior
inspect --format='{{.Size}}' returned only the variant-unique layer
with the new base/variant split, understating by 2+ GB).
- Threshold 2850 → 3500 MB to absorb base additions + arch margin.
Image size:
- Local arm64 build: 3.20 GB. ~390 MB up from prior pi-only equivalent.
- Will tighten threshold once amd64 actuals settle in CI.
Pre-1.0 history preserved at tag pre-v1.0.0-decouple-backup.
Future work:
- v1.1.0: :latest-studio variant (adds pi-studio).
- v1.2.0: :latest-studio-tex variant (adds texlive-xetex for PDF).
- opencode-devbox v2.0.0 will retire INSTALL_PI / pi-only paths.
