v1.15.4: bump opencode 1.15.3 -> 1.15.4

Bundles with the CI hardening landed on main since v1.15.3 (T14/T15 in
the operator backlog):

- Pinned crane install in promote-base-latest (replaces flaky
  imjasonh/setup-crane@v0.4 that depends on api.github.com/releases/latest
  at runtime and periodically rate-limits)
- Skip promote-base-latest on cache-hit base builds (need_build='false')

These will be exercised on this release run \u2014 if the base hash hasn't
drifted since v1.15.3 (likely cache hit), promote-base-latest should
SKIP rather than RUN, and update-description picks up the new tag.

+# CI / Build Pipeline
+
+This directory contains the gitea Actions workflows and the supporting
+documentation for opencode-devbox's CI. If you're investigating *why*
+the build pipeline is shaped the way it is, you're in the right place.
+
+## Workflows in this directory
+
+| File | Trigger | Role |
+|---|---|---|
+| [`workflows/docker-publish-split.yml`](workflows/docker-publish-split.yml) | `push: tags: v*` | **Production release pipeline.** Two-phase split-base build: shared `base-<hash>` published once (skipped on cache hit), then four parallel variant deltas. ~40–80 min wall clock depending on runner count and whether base needs rebuilding. |
+| [`workflows/validate.yml`](workflows/validate.yml) | `push: branches: main` + PR | **Lightweight gate.** amd64-only smoke test of all four variants + `DOCKER_HUB.md` sync check. ~30 min. Fires on every push to `main`. |
+
+## Why the split-base pipeline exists
+
+opencode-devbox publishes **four image variants** (`base`, `omos`, `with-pi`, `omos-with-pi`) × **two architectures** (amd64, arm64) = **eight image tags per release**. Today's runners are 2 self-hosted gitea Actions runners. arm64 builds are emulated under QEMU, which is the dominant cost (~3–5x slower than native).
+
+The four variants share ~95% of their layers (Debian + apt + Node + AWS CLI + mempalace + dev tools + entrypoints). The original `Dockerfile` was a single multi-stage build with `INSTALL_*` build-args gating variant-specific RUNs. BuildKit's per-layer cache key is content-addressed, but as soon as a build-arg-gated `RUN` produces a different layer hash for variant A vs variant B, every subsequent layer also has a different parent → identical commands re-execute per variant. Result: minimal cross-variant cache reuse on a fresh build.
+
+Two improvements were considered:
+
+1. **Reorder the original Dockerfile** so all variant-gated RUNs land at the bottom — modest gain, ~10–20% wall-clock reduction. *Not pursued.*
+2. **Split into `Dockerfile.base` + `Dockerfile.variant`** with the base published as a long-lived shared image — significant gain, ~50–70% wall-clock reduction with hash-driven cache reuse. *Pursued.*
+
+The split-base architecture is what the `docker-publish-split.yml` workflow exercises.
+

+```
+
+### Step 1: `base-decide`
+
+Compute a SHA-256 hash over the inputs that determine the base image's
+content:
+
+```sh
+{
+  cat Dockerfile.base
+  find rootfs -type f -print0 | sort -z | xargs -0 cat
+  cat entrypoint.sh entrypoint-user.sh
+} | sha256sum | cut -c1-12
+```
+
+The 12-character truncated hash becomes `base-<hash>`. Probe Docker Hub
+for this tag via `docker manifest inspect`:
+
+- If it exists → set `need_build=false`. `build-base` is skipped entirely.
+- If it doesn't → set `need_build=true`. `build-base` runs.
+
+This is the core cache-reuse mechanism. Version-bump-only releases
+(only `Dockerfile.variant` or build-args changed) hit the cache. Releases
+that change anything in the base — apt packages, AWS CLI, Node version,
+locale list, entrypoint scripts — pay the full base-build cost once.
+
+### Step 2: `build-base` (conditional)
+
+Only runs when `need_build=true`. Multi-arch (amd64 + arm64) build of
+`Dockerfile.base`, pushed to `joakimp/opencode-devbox:base-<hash>`.
+Registry cache via `--cache-from/--cache-to` reduces incremental rebuilds
+when only one or two layers changed.
+
+The base image is **not** tagged `base-latest` here — that promotion
+happens at the very end after all variants succeed (see step 5).
+
+### Step 3: `smoke-*` (×4, parallel)
+
+For each variant: build amd64-only against the base tag, load into
+local docker, run [`scripts/smoke-test.sh`](../scripts/smoke-test.sh).
+Variant build-args:
+
+| variant | INSTALL_OPENCODE | INSTALL_OMOS | INSTALL_PI |
+|---|---|---|---|
+| `base` | true | false | false |
+| `omos` | true | true | false |
+| `with-pi` | true | false | true |
+| `omos-with-pi` | true | true | true |
+
+Smoke runs `--variant <name>` to enable variant-specific assertions.
+Gate the publish: a smoke failure for variant X blocks `build-variant-X`.
+
+### Step 4: `build-variant-*` (×4, parallel)
+
+For each variant that passed smoke: multi-arch (amd64 + arm64) build of
+`Dockerfile.variant`, pushed to Docker Hub with the user-facing release
+tags:
+
+| Build job | Tags pushed |
+|---|---|
+| `build-variant-base` | `vX.Y.Z`, `latest` |
+| `build-variant-omos` | `vX.Y.Z-omos`, `latest-omos` |
+| `build-variant-with-pi` | `vX.Y.Z-with-pi`, `latest-with-pi` |
+| `build-variant-omos-with-pi` | `vX.Y.Z-omos-with-pi`, `latest-omos-with-pi` |
+
+The `latest*` aliases are only updated when `promote_latest=true` (the
+manual dispatch input) — for test runs, `promote_latest=false` keeps the
+production aliases pointing at the previous good release.
+
+### Step 5: `promote-base-latest`
+
+Once all four variants successfully publish, re-tag `base-<hash>` as
+`base-latest` using `crane copy`. This is a **manifest-level re-tag, not
+a rebuild** — it touches only Docker Hub's image index, takes seconds,
+and is atomic.
+
+The reason this happens *after* variants succeed (rather than alongside
+`build-base`) is so a partial failure leaves `base-latest` pointing at
+the previous known-good base. External consumers who pin to
+`base-latest` (e.g. the planned pi-devbox repo) never see a broken base.
+
+### Step 6: `update-description`
+
+Push the generated `DOCKER_HUB.md` to the Hub repo's `full_description`
+field via the Hub REST API. Same step as the production pipeline.
+
+## NPM_CONFIG_PREFIX gotcha (variant override pattern)
+
+The base sets
+
+```
+ENV NPM_CONFIG_PREFIX=/home/developer/.pi/npm-global
+```
+
+This is intentional — it makes `pi install npm:<pkg>` and `npm install -g`
+land on the `devbox-pi-config` named volume at runtime, so user-installed
+packages survive container recreate AND image rebuild.
+
+But the *variant build* inherits this prefix at build time. If left as-is,
+`npm install -g opencode-ai@$VERSION` in `Dockerfile.variant` would
+install opencode into `/home/developer/.pi/npm-global/...`, which is then
+**shadowed by the volume mount at runtime** → opencode disappears from
+PATH on first start.
+
+Fix: each `npm install -g` in `Dockerfile.variant` overrides the prefix
+per-RUN:
+
+```dockerfile
+RUN NPM_CONFIG_PREFIX=/usr npm install -g opencode-ai@${OPENCODE_VERSION}
+```
+
+Baked binaries land on `/usr/bin/...` (system prefix), survive the volume
+mount. Runtime-installed user packages still land on
+`~/.pi/npm-global/...`. Both visible on PATH.
+
+## Cache strategy
+
+Two registry caches are configured:
+
+```yaml
+cache-from: type=registry,ref=joakimp/opencode-devbox:base-buildcache
+cache-to:   type=registry,ref=joakimp/opencode-devbox:base-buildcache,mode=max
+
+cache-from: type=registry,ref=joakimp/opencode-devbox:base-variant-buildcache
+cache-to:   type=registry,ref=joakimp/opencode-devbox:base-variant-buildcache,mode=max
+```
+
+`mode=max` exports cache for *all* layers, not just the final image's
+layers. Important for multi-arch builds where the cross-arch layer reuse
+matters more.
+
+## Wall-clock estimates
+
+| Scenario | Production pipeline | Split-base pipeline |
+|---|---|---|
+| Version-bump-only release (only opencode/pi/omos version changed) | ~165–180 min | **~30–40 min** (base cache hit) |
+| Base-touching release (apt/Node/Debian/entrypoint change) | ~165–180 min | **~70–90 min** (base rebuilds) |
+
+The split-base pipeline pays its dues on base-touching releases (which are
+infrequent — a few times a year for Debian / Node major version bumps).
+Most releases are version-bumps and ride the cache.
+
+## Validate workflow
+
+[`validate.yml`](workflows/validate.yml) is the lightweight gate that runs
+on every push to `main` and on PRs. It:
+
+1. Runs `scripts/generate-dockerhub-md.py --check` to enforce
+   `DOCKER_HUB.md` is in sync with `HUB_TEMPLATE`.
+2. Builds each of the four variants amd64-only (no multi-arch, no push)
+   and runs `scripts/smoke-test.sh`.
+
+This catches regressions before they reach a tag push. Wall clock ~30 min.
+
+## Runner expectations
+
+- **Image:** `catthehacker/ubuntu:act-latest`. Each job runs inside a
+  fresh container of this image. Don't assume any pre-installed
+  toolchains beyond what catthehacker ships.
+- **Disk pressure:** the runner host has ~40 GB of usable overlay space,
+  often 70%+ used at job start. Every job that does `load: true` (smoke)
+  starts with a `Reclaim runner disk` step that strips
+  catthehacker-resident toolchains (Android SDK, .NET, Swift, GHC, JVM,
+  Boost, Chromium, PowerShell) and prunes stale docker state. Don't
+  remove these steps without testing on a fresh runner.
+- **Concurrency:** 2 runners. Jobs in the same workflow run can fan out to
+  both; jobs in *different* workflow runs are serialized by gitea's queue.
+  The `concurrency: { group: ${{ workflow }}-${{ ref }}, cancel-in-progress: false }`
+  setting keeps tag pushes from racing each other but allows
+  per-PR/per-branch parallelism.
+- **Workflow visibility in UI:** gitea Actions only surfaces workflows
+  from the **default branch** in the web UI's workflow list, even for
+  `workflow_dispatch` triggers. Workflows on feature branches are
+  invisible until merged to `main`.
+- **Disk reclaim quirk:** `actions/{upload,download}-artifact@v4+` does
+  not work on Gitea (depends on a GitHub-only Artifact API). Stick to
+  `@v3` if matrix-fanout-with-artifacts is ever needed. We avoided this
+  by using `docker/build-push-action@v7` with comma-separated
+  `platforms: linux/amd64,linux/arm64` — natively does multi-arch push
+  in a single job, no artifact dance.
+
+## Migration plan: split-base → production
+
+1. **Validate the split-base dispatch.** Trigger
+   `docker-publish-split.yml` manually with `release_tag=v0.0.0-split-test`
+   and `promote_latest=false`. Confirm all jobs go green, image sizes
+   match the production baseline within ~10%, and no unexpected layer
+   rebuilds appear in `build-variant-*` logs after the FROM line.
+2. **Run a second dispatch** to confirm cache-hit behavior:
+   `base-decide` should set `need_build=false`, `build-base` should be
+   skipped entirely, total wall clock should drop to ~25–40 min.
+3. **Cut over** — *done as of v1.14.50.* `docker-publish-split.yml` now
+   triggers on `push: tags: v*`. `docker-publish.yml` and original
+   `Dockerfile` deleted.
+4. **Tag a release.** First production release on the new pipeline.

+# Lightweight validation on pushes to main. Builds single-arch (amd64),
+# runs the smoke test, and checks image size — without pushing anything
+# to Docker Hub. Tag pushes are handled by docker-publish-split.yml which
+# does the full multi-arch split-base build-and-push.
+#
+# Trade-off: variant builds here use the published `base-latest` image
+# from Docker Hub as their parent, NOT a locally-built base. This is
+# because `docker/build-push-action@v7` runs each invocation in its own
+# buildx container context, so an image loaded into the host docker
+# daemon by step N is not visible to step N+1's buildx invocation.
+# Building base + variant in the same job would require either pushing
+# the base to a registry or sharing a buildx instance across steps — both
+# significantly more complex than just using the published base.
+#
+# Consequence: PRs/pushes that change Dockerfile.base, rootfs/, or
+# entrypoint*.sh are NOT exercised by this workflow. The release path
+# (docker-publish-split.yml on tag push) does build the new base, so
+# release tags are the gate that fully validates base-image changes.

 ## Project overview
 
-Docker image packaging [opencode](https://opencode.ai) into a production-ready dev container. Two image variants (base and omos) are published to Docker Hub via Gitea Actions CI. Not a library or application — this is infrastructure (Dockerfile, entrypoint scripts, docker-compose, documentation).
+Docker image packaging [opencode](https://opencode.ai) into a production-ready dev container. Image variants are published to Docker Hub via Gitea Actions CI. Not a library or application — this is infrastructure (Dockerfiles, entrypoint scripts, docker-compose, documentation).
 
 ## File roles
 
-- `Dockerfile` — single multi-stage build for both variants. OMOS variant is controlled by `INSTALL_OMOS=true` build arg. All GitHub-sourced binaries are pinned with version ARGs.
-- `entrypoint.sh` — runs as root: UID/GID adjustment, SSH permissions, volume ownership fixes. Then drops to developer via gosu.
-- `entrypoint-user.sh` — runs as developer: git config, opencode.json generation from env vars, OMOS setup.
-- `DOCKER_HUB.md` — pushed to Docker Hub description via CI API call. Must stay under 25KB. Short description field must be ≤100 bytes.
-- `README.md` — source repo documentation. Must stay in sync with DOCKER_HUB.md (both describe the same features but for different audiences).
-- `.gitea/workflows/docker-publish.yml` — CI pipeline: three parallel jobs (build-base, build-omos, update-description). Triggered by tag push only.
+- `Dockerfile.base` — variant-independent layers (apt, locales, AWS CLI, Node.js, mempalace, gitea-mcp, user setup, chromadb prewarm, ENVs, entrypoints). Published as `joakimp/opencode-devbox:base-<sha12>`. Rebuilt only when its content hash changes.
+- `Dockerfile.variant` — `FROM`s the base and adds only opencode/omos/pi installs gated by build args: `INSTALL_OPENCODE` (default true), `INSTALL_OMOS`, `INSTALL_PI`, and `INSTALL_MEMPALACE`. All GitHub-sourced binaries are pinned with version ARGs.
+- `entrypoint.sh` — runs as root: UID/GID adjustment, SSH permissions, volume ownership fixes (skipped via `.devbox-owner` sentinel when ownership is already correct). Then drops to developer via gosu. Volume ownership loop covers `~/.pi/` when `INSTALL_PI=true`.
+- `entrypoint-user.sh` — runs as developer: git config, opencode.jsonc generation (delegated to `generate-config.py`), pi-toolkit + pi-extensions deploy (when pi installed), pi settings.json bootstrap, mempalace pi-bridge symlink, skillset auto-deploy from mounted skillset repo, OMOS setup.
+- `rootfs/usr/local/lib/opencode-devbox/generate-config.py` — generates `~/.config/opencode/opencode.jsonc` from env vars. Never overwrites an existing config (checks both `.json` and `.jsonc`). Auto-registers MCP servers for detected tools (mempalace via `mempalace-mcp`, gitea-mcp, context7 remote endpoint).
+- `scripts/smoke-test.sh` — post-build image verification. Asserts binary presence, opencode startup, entrypoint correctness, config generation idempotency, and image size thresholds. Used by both CI workflows.
+- `scripts/generate-dockerhub-md.py` — generates `DOCKER_HUB.md` from a hand-maintained `HUB_TEMPLATE` constant. `--check` fails if the committed file is out of sync (enforced by the `validate` workflow).
+- `DOCKER_HUB.md` — **auto-generated** from `HUB_TEMPLATE` in `scripts/generate-dockerhub-md.py`. Do not edit directly. Pushed to Docker Hub description via CI API call. Must stay under 25 kB. Short description field must be ≤100 bytes.
+- `README.md` — authoritative source documentation for everything in this repo. Independent of `DOCKER_HUB.md`: the Hub doc is hand-maintained in the generator's `HUB_TEMPLATE` and intentionally slim, linking back to the gitea README for depth.
+- `.gitea/README.md` — **read this first** if you're touching CI. Architectural overview of the build pipeline (production vs split-base), wall-clock estimates, NPM_CONFIG_PREFIX gotcha, runner expectations, migration plan.
+- `.gitea/workflows/validate.yml` — lightweight amd64 build + smoke test on push to main and PRs. Also runs the DOCKER_HUB.md sync check.
+- `.gitea/workflows/docker-publish-split.yml` — production CI pipeline on tag push (`v*`). Two-phase split-base: computes base hash, conditionally builds base, runs 4 parallel smoke tests, then 4 parallel multi-arch variant builds, promotes `base-latest` alias, updates Docker Hub description.
 
 ## Versioning scheme
 
-Tags follow `v{opencode_version}{letter}` — e.g. `v1.4.3k`. The number matches the opencode npm version. The letter suffix increments for container-level changes (tooling, docs, CVE fixes) on the same opencode version. CI produces four Docker Hub tags per release: `vX.Y.Zn`, `latest`, `vX.Y.Zn-omos`, `latest-omos`.
+Tags follow `v{opencode_version}[letter]` — e.g. `v1.14.20` for the first build on a new opencode release, and `v1.14.20b`, `v1.14.20c`, … for subsequent rebuilds on the same opencode version.
+
+- The number tracks the opencode npm version (see `OPENCODE_VERSION` ARG in `Dockerfile.variant`).
+- **No letter suffix** on the first build of a new opencode version — the bare `v{opencode_version}` tag is the canonical release.
+- **Letter suffix is the build ordinal**, starting at `b` for the second build. The letter `a` is **never used** — think of the suffix as counting rebuilds: `b = 2nd, c = 3rd, d = 4th, …`. For opencode version `1.14.20`: first build `v1.14.20`, second `v1.14.20b`, third `v1.14.20c`, and so on.
+- A letter suffix is only used for container-level rebuilds — tooling changes, CVE fixes, doc-driven rebuilds, entrypoint bugfixes — that don't change the underlying opencode version.
+
+CI produces eight Docker Hub tags per release: `vX.Y.Z[n]`, `latest`, `vX.Y.Z[n]-omos`, `latest-omos`, `vX.Y.Z[n]-with-pi`, `latest-with-pi`, `vX.Y.Z[n]-omos-with-pi`, `latest-omos-with-pi` — one tag pair (versioned + floating alias) per build variant.
+
+When bumping the opencode version, bump `OPENCODE_VERSION` in `Dockerfile.variant` and update the comment in `.env.example` if it names a specific model/version for context.
 
 ## Critical conventions
 
-- **entrypoint.sh volume ownership loop** — when adding a new named volume mount point, add it to the `for dir in ...` loop in `entrypoint.sh` so root-owned volumes get chowned on startup.
-- **Three docs to keep in sync** — Dockerfile changes that add tools or features must be reflected in `README.md`, `DOCKER_HUB.md`, and `.env.example`. The docker-compose examples in both docs must match the source `docker-compose.yml` pattern.
-- **GitHub-sourced binaries** — fzf, gosu, git-lfs, neovim, bat, eza, zoxide, uv, rustup are installed from upstream releases (not apt) with pinned versions. Use the same `ARCH` case-switch pattern for multi-arch support (amd64/arm64).
+- **entrypoint.sh volume ownership loop** — when adding a new named volume mount point, add it to the `for dir in ...` loop in `entrypoint.sh` so root-owned volumes get chowned on startup. The loop writes a `.devbox-owner` sentinel after a successful chown so subsequent starts skip the recursive walk. Users should not touch these files.
+- **Documentation coupling on release** — four docs co-vary and drift in lockstep when not updated together:
+  - `README.md` is the source of truth for user-facing build/run/config detail.
+  - `DOCKER_HUB.md` is auto-generated from `HUB_TEMPLATE` in `scripts/generate-dockerhub-md.py`. CI's `--check` run fails if it's stale. Hub-facing copy is intentionally slim (~5.5 kB, ~78% headroom against the 25 kB Hub limit) — update the template here when image variants, quick-start flow, or the elevator pitch change. README.md no longer feeds into Hub, so README edits do NOT require regenerating DOCKER_HUB.md.
+  - `CHANGELOG.md` records every release. When cutting a tag, **promote `## Unreleased` to `## vX.Y.Z[n] — YYYY-MM-DD` BEFORE pushing the tag** so the tag points at a CHANGELOG that names itself. Keep entries reverse-chronological (newest at top, after the `Unreleased` block). Doc-only updates that happen post-tag (Hub description live-patches, README clarifications) get a fresh `## Unreleased` block with a note that they don't trigger a new image build.
+  - `AGENTS.md` (this file) carries domain facts that change on structural releases — tag-count statements, CI job lists, install contracts. After any change to `.gitea/workflows/*.yml` or the variant matrix, grep this file for stale numbers (`grep -nE "four|eight|all [0-9]"`).
+  - `.env.example` must be hand-updated to match Dockerfile/entrypoint behavior — it is not auto-generated.
+
+  Release-day checklist: README → (regenerate DOCKER_HUB.md only if HUB_TEMPLATE changed) → promote CHANGELOG Unreleased → grep AGENTS.md for stale counts → commit → tag → push tag.
+- **GitHub/Gitea-sourced binaries float by default** — gosu, fzf, git-lfs, nvim, bat, eza, zoxide, uv, gitea-mcp, Go, oh-my-opencode-slim all default to `latest`. Each build-time install step reads the `/releases/latest` Location redirect (or the go.dev JSON feed for Go) and derives the concrete version. Use the same `ARCH` case-switch pattern for multi-arch support (amd64/arm64). Intentional pins: `OPENCODE_VERSION` (drives the image tag), `NODE_VERSION=22` (major pin), `DEBIAN_VERSION=trixie-slim` (OS base). Adding a new upstream tool: follow the existing floated-version pattern, don't hardcode a specific tag.
+- **Resolved versions are logged by the smoke test** — `scripts/smoke-test.sh` prints a "Resolved component versions" table as its first step. CI logs always capture what got baked into a given image even when ARGs default to `latest`.
 - **Shell scripts use `set -euo pipefail`** — both entrypoints are strict. Errors in volume chown or SSH permission operations are intentionally suppressed with `|| true`.
+- **MemPalace install path** — installed via `uv tool install` into `/opt/uv-tools/mempalace/`. Both the `mempalace` CLI and the `mempalace-mcp` MCP server binary are shipped as entry points by the mempalace package itself and placed on PATH by uv as shims whose shebangs point at the venv's Python. No hand-rolled wrapper is needed. Do not use `pip install --break-system-packages` — that was the previous approach and has been removed. Do not use `["python3", "-m", "mempalace.mcp_server"]` in `opencode.jsonc` — system Python can't import from the uv venv.
+- **generate-config.py idempotency** — the script MUST never overwrite an existing `opencode.jsonc` or legacy `opencode.json`. Config persists in the `devbox-opencode-config` named volume; accidentally clobbering that file would destroy hand-edits. The smoke test asserts this.
+- **Skillset auto-deploy** — on every container start, `entrypoint-user.sh` looks for a skillset repo (detection order: `$SKILLSET_CONTAINER_PATH` → `$HOME/skillset` → `/workspace/skillset`) and runs `deploy-skills.sh --bootstrap --prune-stale`. This creates relative symlinks in `~/.agents/skills/` and `~/.config/opencode/instructions/`. Do NOT bind-mount `~/.agents/skills/` from the host — the container manages its own skills with relative symlinks that differ from the host's. The named volume `devbox-opencode-config` persists the deployed config across restarts.
+- **Config persistence via named volume** — `devbox-opencode-config` is a Docker named volume mounted at `~/.config/opencode/`. It is NOT a host bind mount by default. This separation allows both native and containerized opencode to coexist on the same machine without symlink conflicts. Users who need to override can replace the named volume with a host bind mount in their compose file. **Same pattern for pi:** `devbox-pi-config` is mounted at `~/.pi/` and persists user toggles (`/ext`-disabled extensions), `~/.pi/agent/settings.json` edits, and — because `NPM_CONFIG_PREFIX` is set to `~/.pi/npm-global` — anything installed via `pi install npm:...` or `npm install -g` as the developer user, across container recreate AND image rebuild.
+- **pi install contract** — `INSTALL_PI=true` (default false) opt-in build arg. The baked `pi` binary is npm-installed globally to `/usr` at build time (system prefix). At runtime, `NPM_CONFIG_PREFIX=/home/developer/.pi/npm-global` is set in the image ENV with that prefix's `bin/` prepended to `PATH` — so any `pi install npm:...` or `npm install -g` invoked by the developer user lands on the named volume and survives everything except `docker compose down -v`. The new ENVs are declared *after* all build-time `npm install -g` calls in the Dockerfile so they don't redirect the baked installs into a path that the volume mount would later shadow. If the user runs `npm install -g @earendil-works/pi-coding-agent` themselves, the user-installed copy on the volume wins via `PATH` order; otherwise image rebuild is the upgrade path for the baked pi (same contract as `OPENCODE_VERSION`). The pi-toolkit and pi-extensions repos are git-cloned into `/opt/` at build time, then their `install.sh` runs from `entrypoint-user.sh` on each container start to symlink into `~/.pi/agent/` (which lives on the named volume). The mempalace pi-bridge is symlinked manually from `/opt/mempalace-toolkit/extensions/pi/mempalace.ts` — we do NOT call mempalace-toolkit's full `install.sh` because its `install_skill` step would race with skillset auto-deploy `--prune-stale`.
+- **Pi deploy ordering matters in entrypoint-user.sh** — `pi-toolkit` runs first (creates `keybindings.json` symlink and writes pi-env.zsh), then `pi-extensions`, then `settings.json` template bootstrap, then mempalace bridge symlink. mempalace-toolkit's `check_pi_toolkit` probe (when called from the host install path) expects keybindings to already be present — not currently called from container, but ordering matches host convention.
+- **Default CMD is `bash -l`** — not a harness. `docker compose run --rm devbox` drops the user into a login shell to choose: `aws sso login`, then `opencode` or `pi` (or any tool). Pass the harness explicitly to launch directly: `docker compose run --rm devbox opencode` / `docker compose run --rm devbox pi`. `docker compose exec` bypasses entrypoint+CMD entirely (existing user workflow unchanged).
 - **Docker Hub description update** — uses `/v2/auth/token` endpoint (not the deprecated `/v2/users/login`). Auth uses `identifier`/`secret` fields, returns `access_token`, sent as `Bearer`. Short description must be ≤100 bytes.
 
 ## CI quirks
 
 - Both build jobs include an IPv4 preference step (`gai.conf` + `driver-opts: network=host` for buildx) to work around intermittent IPv6 failures on the Gitea runners.
 - `update-description` job runs only when both builds succeed (`needs: [build-base, build-omos]`).
-- Tags must be pushed to trigger CI. Pushing to `main` alone does not build images.
+- Tags must be pushed to trigger the publish workflow. The validate workflow runs on push to main and PRs.
+- Smoke tests run on amd64 only (single-arch load into the local daemon). The multi-arch push happens after smoke passes.
+- **Gitea Actions runner has ~40 GB disk, often 70%+ used at job start.** All eight `load: true` jobs (`validate-base`, `validate-omos`, `validate-with-pi`, `validate-omos-with-pi`, `smoke-base`, `smoke-omos`, `smoke-with-pi`, `smoke-omos-with-pi`) include a `Reclaim runner disk` step that strips catthehacker-resident toolchains and prunes stale docker state before `setup-buildx-action`. Build jobs use a lighter version (push-by-digest doesn't need `docker system prune`). Don't remove these steps without testing on a fresh runner.
+- **`docker/build-push-action@v7` with `platforms: linux/amd64,linux/arm64` handles multi-arch push natively in a single job** — produces a proper manifest list, no matrix or merge step needed. An earlier revision split into per-arch matrix jobs with digest artifacts, but that pattern requires `actions/{upload,download}-artifact@v4+` which Gitea Actions doesn't support (see below).
+- **`actions/upload-artifact` and `actions/download-artifact` must stay at @v3 on Gitea.** v4+ uses a GitHub-Enterprise-specific Artifact API; runs fail with `GHESNotSupportedError`. If you need artifacts for a new reason (build logs, SBOMs, etc.), pin @v3 explicitly.
+- **Step scripts run under `/bin/sh` (dash), not bash.** Avoid bash-isms like `${VAR//a/b}` parameter-pattern substitution; use POSIX alternatives (`tr`, `sed`) or declare `shell: bash` on the step.
+- **`BUILDKIT_PROGRESS=plain`** is set at workflow level on `docker-publish-split.yml` so arm64-under-QEMU builds log each layer line-by-line. The default collapsed progress UI hides which step is stalled, which made diagnosing earlier hangs expensive.
 
 ## Testing changes
 
-No test suite. Verify by:
-1. Building locally: `docker compose build`
-2. Running: `docker compose run --rm devbox bash`
-3. Checking tool availability inside container: `nvim --version`, `bat --version`, `uv --version`, etc.
-4. For entrypoint changes: test with a non-1000 UID workspace to verify UID adjustment and volume ownership fixes.
+The smoke test (`scripts/smoke-test.sh`) is the canonical check and runs automatically in CI. To run locally:
+
+```bash
+# Base image
+docker compose build
+bash scripts/smoke-test.sh opencode-devbox --variant base
+
+# OMOS image
+docker build --build-arg INSTALL_OMOS=true -t opencode-devbox:omos .
+bash scripts/smoke-test.sh opencode-devbox:omos --variant omos
+```
+
+For manual/exploratory testing:
+1. `docker compose run --rm devbox bash`
+2. Check specific tools inside: `nvim --version`, `bat --version`, `uv --version`, `mempalace --help`, etc.
+3. For entrypoint changes: test with a non-1000 UID workspace to verify UID adjustment, volume ownership fixes, and the `.devbox-owner` sentinel behavior.
+4. For `generate-config.py` changes: run standalone with `HOME=/tmp/fake OPENCODE_PROVIDER=anthropic python3 rootfs/usr/local/lib/opencode-devbox/generate-config.py`.

+## Unreleased
+
+## v1.15.4 — 2026-05-18
+
+opencode 1.15.3 → 1.15.4 bump (one upstream patch release), bundled with the CI hardening that landed on main between v1.15.3 and now.
+
+- **Bump:** opencode 1.15.3 → 1.15.4 (`OPENCODE_VERSION` in `Dockerfile.variant`).
+- **CI: pinned crane install in `promote-base-latest`.** Replaced `imjasonh/setup-crane@v0.4` with a direct `curl + tar` install pinned to crane v0.21.6. The action's bootstrap script calls `api.github.com/.../releases/latest` to discover what crane version to install. That call periodically rate-limits and produces `tag=null` → the action downloads `releases/download/null/...` → 404 → `gzip: unexpected end of file` → exit 2. We hit this on v1.15.3 (cosmetic failure since base-latest was already correct from cache hit). Pinned install removes the runtime GitHub API dependency entirely. Bump `CRANE_VERSION` deliberately when wanting updates, same pattern as the other GitHub-sourced binaries in the Dockerfile layer.
+- **CI: skip `promote-base-latest` on cache-hit base builds.** When the base layer hash hasn't changed (cache-hit on the existing `base-<hash>` from a previous run), `base-latest` already points at the correct digest, so the retag is a tautology. Job now skipped entirely when `needs.base-decide.outputs.need_build == 'false'`. Manual `workflow_dispatch` with `promote_latest: true` overrides the gate as an escape hatch for hand-recovery scenarios.
+- No image-side changes from the v1.15.3 baseline beyond the opencode npm version. Smoke thresholds unchanged.
+

+
+Rebuild of v1.15.0 with one fix — v1.15.0's `omos` variant landed at 3206 MB, 6 MB over the 3200 MB smoke threshold, so `smoke-omos` failed and `build-variant-omos` was skipped. opencode 1.15.0 grew slightly vs 1.14.50, leaving zero headroom on the existing threshold.
+
+- **Smoke threshold bump:** `omos` 3200 → 3300 MB, `omos-with-pi` 3400 → 3500 MB. Restores ~100 MB headroom for routine apt-get upgrade drift between releases. Documented inline in `scripts/smoke-test.sh`. No image-side changes — cache hits across the board, just a re-publish on the bumped threshold.
+
+## v1.15.0 — 2026-05-15
+
+opencode 1.14.50 → 1.15.0 bump (upstream minor release).
+
+- **Bump:** opencode 1.14.50 → 1.15.0 (`OPENCODE_VERSION` in `Dockerfile.variant`).
+- **Resilience:** `git clone` for pi-toolkit and pi-extensions in `Dockerfile.variant` is now wrapped in a 5-attempt retry loop with linear backoff (5s, 10s, 15s, 20s, 25s = up to ~75s total). gitea.jordbo.se occasionally returns transient HTTP 500s on the first request after idle, which previously broke the with-pi and omos-with-pi variant builds. Same pattern landed in pi-devbox repo concurrently.
+- **Docs:** `DOCKER_HUB.md` mentions `joakimp/pi-devbox` as a sibling image — the pi-only build that uses this image's base layer as its parent. Generator template (`scripts/generate-dockerhub-md.py`) updated and regenerated. Hub size: 5905 bytes (well under the 25 kB limit).
+- **Recovery from v1.14.50c partial publish:** the `latest-omos`, `v1.14.50c-omos` Hub gap is closed by this release — `latest-omos` will move forward to v1.15.0 once all four variants publish cleanly. Users on the floating tag were unaffected (still pointing at v1.14.41b until now).
+
+## v1.14.50c — 2026-05-14
+
+Recovery release for v1.14.50b's missing variants. v1.14.50b shipped only the `base` variant; `omos`, `with-pi`, and `omos-with-pi` were lost to a runner-fleet incident (see postmortem below).
+
+No container-side changes. This is a tag-only retag to re-run the build on a now-healthy runner fleet. Same `base-35ee5fe7861a` from v1.14.50b is reused via hash-cache hit; only the four variant deltas are rebuilt and published.
+
+### Postmortem: v1.14.50 / v1.14.50b runner-fleet incident
+
+Two orthogonal runner-host issues compounded across runs 285–291:
+
+1. **AVX-less runner shadowing the new fleet.** A pre-migration `act_runner` container on `nyvaken` (Sandy Bridge E3-12xx, has AVX but no AVX2; 4 weeks old, name `act_runner-runner-1`) collided with the orchestrator's freshly deployed `runner-1` VM (Broadwell-EP host, fully AVX2-capable). Gitea scheduled jobs to both. Jobs landing on the nyvaken container `npm install -g opencode-ai@1.14.50` succeeded, then ran `opencode --version` postinstall → the bundled Bun (v1.3.13 baseline) emitted `CPU lacks AVX support`, panicked, and SIGILLed (exit code 132).
+2. **Containerd shared-state race at `capacity: 2`.** The new VM-based runners initially ran `act_runner` with `capacity: 2`, scheduling two concurrent jobs on a single host. Both jobs would invoke `docker/setup-buildx-action@v4`, which pulls `moby/buildkit:buildx-stable-1`. Containerd's content store raced on identical sha256 ingestion, surfacing as `commit failed: rename .../ingest/.../data .../blobs/sha256/...: no such file or directory` or `failed to extract layer: failed to Lchown ...`.
+
+A secondary issue surfaced: **Proxmox VM `cpu:` field defaults mask AVX**. The newly-cloned runner VMs had no explicit `cpu:` line in `qm config` and inherited Proxmox's recent default `x86-64-v2-AES`, which excludes AVX even though the Broadwell-EP host silicon has full `avx2`. Fix: `qm set <vmid> --cpu x86-64-v3` (or `host` for full passthrough), then `qm shutdown` + `qm start` (live reboot is not enough). Verified inside guest with `grep -m1 -oE 'avx[2]?' /proc/cpuinfo`.
+
+Additionally, when `promote-base-latest`'s `needs:` graph requires *all four* `build-variant-*` jobs to succeed, partial publishes leave the `base-latest` Hub alias never advancing. Workaround used during recovery: manually re-tag the new base hash via Docker Hub registry manifest API (`PUT /v2/<repo>/manifests/base-latest` with the body of `GET /v2/<repo>/manifests/base-<sha>`) using a granular Hub PAT. No blob copy needed since blobs are content-addressed.
+
+### Recovery actions taken (orchestrator + this repo)
+
+- Orchestrator (cloud-init + ansible repos): set explicit `cpu_type: x86-64-v3` in all runner host yaml files; provision.sh now applies `qm set --cpu` after clone; added runner-3 on proxmox003 for anti-affinity (one runner per Proxmox node); dropped `capacity: 2 → 1` on all runners; bumped `act_runner` 0.3.1 → 0.6.1 across the fleet; documented the CPU-type gotcha as gotcha #9 in cloud-init AGENTS.md and a section in proxmox-guide.md.
+- User: retired the legacy `act_runner-runner-1` container on nyvaken; cleaned up stale runner registrations in Gitea Site Admin → Actions → Runners.
+- This repo: no changes needed in Dockerfile.base / Dockerfile.variant; v1.14.50c is a tag-only retag.
+
+### Fleet state at v1.14.50c
+
+3 runners (runner-1@proxmox001, runner-2@proxmox002, runner-3@proxmox003), all `act_runner` v0.6.1, all `capacity: 1`, all expose AVX + AVX2 to the guest. No name collisions. Estimated wall clock for v1.14.50c (cache-hit base, 4 variant deltas across 3 runners with capacity:1): ~40–50 min.
+
+## v1.14.50b — 2026-05-14
+
+Rebuild of v1.14.50 with two fixes — the v1.14.50 release was incomplete (smokes failed under containerd contention; build-variant jobs skipped; base-latest never promoted to Docker Hub).
+
+- **Force fresh base rebuild.** Added a `BASE_REBUILD_DATE` comment header to `Dockerfile.base` to invalidate the content hash and trigger a full base rebuild. Picks up ~5 days of Debian trixie security updates and other apt-tracked packages. The comment also documents the pattern for future intentional base-rebuilds without other code changes (recommended cadence: once per release).
+- **First publish of `base-latest` alias.** `promote-base-latest` runs unconditionally on tag push (`PROMOTE_LATEST=true`), so this release is the first to put `joakimp/opencode-devbox:base-latest` on Docker Hub. Required before pi-devbox (and any other downstream image FROMing the base) can build.
+
+## v1.14.50 — 2026-05-14
+
+opencode 1.14.44 → 1.14.50 bump. First release on the split-base build pipeline.
+
+- **Bump:** opencode 1.14.44 → 1.14.50 (`OPENCODE_VERSION` in `Dockerfile.variant`).
+- **Infrastructure: split-base pipeline cutover.** `Dockerfile.base` + `Dockerfile.variant` replace the single `Dockerfile`. `docker-publish-split.yml` (now renamed to `docker-publish.yml` in spirit — triggers on `push: tags: v*`) replaces the old `docker-publish.yml`. The original `Dockerfile` and `docker-publish.yml` are deleted. Hash-driven base reuse: version-bump-only releases skip the base build entirely (~40–80 min wall clock with 4 runners vs ~165–180 min previously). Validated across two `workflow_dispatch` test runs (`:v0.0.0-split-test` tags on Docker Hub).
+- **Fix:** `echo -e` heredoc replaced with POSIX-compatible brace-block for multiline `$GITHUB_OUTPUT` writes in the four `build-variant-*` jobs. `echo -e` does not interpret `\n` in `/bin/sh` (dash), causing `steps.tags.outputs.tags` to be empty and buildx to fail with "tag is needed when pushing to registry".
+- **Docs:** New `.gitea/README.md` — architectural overview of the split-base pipeline, hash logic, wall-clock estimates, runner expectations, and the migration plan.
+
+## v1.14.44 — 2026-05-09
+
+opencode 1.14.42 → 1.14.44 bump (1.14.43 skipped upstream). Also completes the matrix coverage that v1.14.42 missed: `build-omos-with-pi` failed mid-publish on v1.14.42 due to an upstream npm CDN propagation race — `oh-my-opencode-slim@1.0.7` had been published declaring a dependency on `@opencode-ai/sdk@1.14.44`, and our build hit the registry within ~2 minutes of that SDK version landing, before the tarball had propagated across npm's CDN. The build returned 404 on the SDK fetch even though the manifest's `dist-tags.latest` already pointed at 1.14.44. Tarball is now fully fetchable; v1.14.44 builds cleanly across all four variants.
+
+- **Bump:** opencode 1.14.42 → 1.14.44 (`OPENCODE_VERSION` build-arg default in both `Dockerfile` and `Dockerfile.variant`).
+
+Known gap: `joakimp/opencode-devbox:v1.14.42-omos-with-pi` and the corresponding `latest-omos-with-pi` alias were NOT published in the v1.14.42 release (`build-omos-with-pi` job failed for the reason above). `latest-omos-with-pi` continued pointing at v1.14.41b until v1.14.44 published. Users on the `latest-omos-with-pi` floating tag were unaffected; users pulling explicit `:v1.14.42-omos-with-pi` would get a 404 from Hub. Closed by v1.14.44.
+
+## v1.14.42 — 2026-05-09
+
+**Note:** Of the 4 multi-arch variants, 3 published cleanly (`v1.14.42`, `v1.14.42-omos`, `v1.14.42-with-pi`, plus their `latest*` aliases). `build-omos-with-pi` failed during the publish step due to an upstream npm CDN propagation race (see v1.14.44 entry above for detail). Re-running the failed job would have required another full ~3h matrix rerun in gitea Actions; we chose to bump opencode to 1.14.44 instead and let the next tag close the gap.
+
+opencode 1.14.41 → 1.14.42 bump. Carries along all container-side changes accumulated since v1.14.41b: pi package rename to `@earendil-works/*`, npm-prefix-on-volume fix, Hub doc rewrite, README/AGENTS docs catchup.
+
+Image changes:
+
+- **Bump:** opencode 1.14.41 → 1.14.42 (`OPENCODE_VERSION` build-arg default in both `Dockerfile` and `Dockerfile.variant`).
+- **Rename:** `npm install -g @mariozechner/pi-coding-agent` -> `npm install -g @earendil-works/pi-coding-agent` in the `INSTALL_PI=true` build path. Pi moved to its new home at earendil-works on 2026-05-07 (https://pi.dev/news/2026/5/7/pi-has-a-new-home); the old `@mariozechner/*` packages are deprecated on npm with the explicit message 'please use @earendil-works/pi-coding-agent instead going forward', and the version stream has moved on (old top-out 0.73.1; new currently 0.74.0). Anyone npm-installing the old name today gets a deprecation warning + a stale binary. Affects both `Dockerfile` (production single-Dockerfile path) and `Dockerfile.variant` (split-base path on main). README, AGENTS, and `HUB_TEMPLATE` URL refs updated from `github.com/mariozechner/pi-coding-agent` (which now 404s) to `github.com/earendil-works/pi`. Brew install references (`brew install pi-coding-agent`) left as-is: formula still works at 0.73.1 and a homebrew tap update is tracked upstream at earendil-works/pi#2755.
+- **Fix:** `pi install npm:<pkg>` (and any `npm install -g`) by the `developer` user no longer EACCES against the system npm prefix. `NPM_CONFIG_PREFIX` is now `/home/developer/.pi/npm-global` and the prefix's `bin/` is prepended to `PATH`. The directory lives on the `devbox-pi-config` named volume, so user-installed pi packages (themes, skills, extensions) survive container recreation and image rebuilds. Build-time `npm install -g` calls (opencode, pi, oh-my-opencode-slim) are unaffected because the new ENVs are declared after those steps in the Dockerfile, so the baked binaries still install to `/usr` and are not shadowed by the volume mount.
+- **Fix (smoke-test):** `scripts/smoke-test.sh` `oh-my-opencode-slim` check now invokes `npm ls -g` with `NPM_CONFIG_PREFIX=/usr` so it queries the system prefix where the baked install lives. Latent regression from the npm-prefix fix above: default `npm ls -g` started querying the user prefix (`/home/developer/.pi/npm-global`, empty at build time) and missed the baked OMOS install — surfaced when `validate.yml` ran on main after the merge of `feat/split-build`.
+
+Docs:
+
+- **Docs:** `DOCKER_HUB.md` `Image Variants` table now lists all four published variants (`latest`, `latest-omos`, `latest-with-pi`, `latest-omos-with-pi`) instead of only the first two. Generator (`scripts/generate-dockerhub-md.py`) HEADER updated to match.
+- **Docs:** `DOCKER_HUB.md` is now generated from a hand-maintained `HUB_TEMPLATE` constant in `scripts/generate-dockerhub-md.py` instead of a section-by-section transformation of `README.md`. Drops from 24 997 bytes (3 byte headroom) to ~5.5 kB (~78% headroom). The old derive-from-README mechanism (`SECTION_RULES`, `TRIM_SUBSECTIONS`, `REPLACEMENTS`, `split_sections`, `trim_subsections`) is gone — README and Hub doc are now independent surfaces, and most README edits no longer require regenerating `DOCKER_HUB.md`. Trade-off: image-variants table and quick-start flow are now coupled to `HUB_TEMPLATE` and need a manual edit when they change.
+- **Docs:** README pi section gains a `### Setup` paragraph mentioning the prebuilt `latest-with-pi` and `latest-omos-with-pi` Docker Hub tags, mirroring the OMOS section's `latest-omos` mention. "What gets installed" updated to reflect the actual shipped state: 7 pi-extensions (was stale at 6 — mcp-loader was added in pi-extensions but not propagated here), each with a one-line description; mcp-loader gets a paragraph covering its dual-transport (local stdio + remote streamable-HTTP per MCP spec 2025-03-26) capability and the `/mcp` slash command. Clarified that the mempalace bridge is a separate MCP entry point that coexists with mcp-loader rather than being replaced by it.
+- **Docs:** AGENTS.md tag-scheme paragraph corrected from "four Docker Hub tags per release" to eight (the v1.14.41b CI matrix expansion). "Documentation coupling on release" rule updated — README edits no longer require regenerating `DOCKER_HUB.md`. Release-day checklist tightened.
+- **README pi section:** "What gets installed" sub-section updated to reflect the actual shipped state. Was stale: claimed 6 pi-extensions (actually 7 — mcp-loader was added in pi-extensions commit 141bf64 / 7eec49b / 37cc49e but never propagated here). Each extension now has a one-line description; mcp-loader gets a paragraph covering its dual-transport (local stdio + remote streamable-HTTP per MCP spec 2025-03-26) capability and the `/mcp` slash command. Clarified that the mempalace bridge is a separate MCP entry point that coexists with mcp-loader rather than being replaced by it. Added an explicit note that no MCP servers are baked in beyond mempalace — the loader is opt-in via settings.json edits.
+
+## v1.14.41b — 2026-05-08
+
+**Optional pi as second harness.**
+
+- **Feature:** New `INSTALL_PI=true` build arg installs [pi](https://github.com/earendil-works/pi) as an alternative or complementary harness alongside opencode. Both harnesses share the same mempalace install and palace path — wing/diary entries are mutually visible. Adds ~150 MB to the image. Pi version pinned by `PI_VERSION` (default: latest at build time); `pi update` inside the container does not persist across `--rm` containers — image rebuild is the upgrade path, same contract as `OPENCODE_VERSION`.
+- **Feature:** New `INSTALL_OPENCODE=false` build arg builds an image without opencode (e.g. for pi-only use). Default remains `true`. Existing builds and tags are unaffected.
+- **Feature:** New `devbox-pi-config` named volume mounted at `~/.pi/` persists pi user state (settings.json, `/ext`-disabled extensions) across container recreate. Mirrors the `devbox-opencode-config` pattern from v1.14.33.
+- **Feature:** Container clones [pi-toolkit](https://gitea.jordbo.se/joakimp/pi-toolkit) (keybindings, env loader, settings template) and [pi-extensions](https://gitea.jordbo.se/joakimp/pi-extensions) (6 extensions including ext-toggle, todo, ssh-controlmaster, notify, git-checkpoint, confirm-destructive) into `/opt/` at build time. New `PI_TOOLKIT_REF` and `PI_EXTENSIONS_REF` build args (default `main`) pin git refs. The mempalace pi-bridge `mempalace.ts` is symlinked from the existing `/opt/mempalace-toolkit/` clone.
+- **Behavior change:** Default container CMD changed from `["opencode"]` to `["bash", "-l"]`. `docker compose run --rm devbox` (no command) now drops to a login shell so users can pick `opencode` or `pi` (or run `aws sso login` first). To preserve the old behavior, pass the harness explicitly: `docker compose run --rm devbox opencode`. `docker compose exec` workflows are unaffected (they bypass the entrypoint and CMD).
+- **Performance:** chromadb's all-MiniLM-L6-v2 ONNX embedding model (~80 MB) is now pre-warmed at image build time under `~/.cache/chroma/onnx_models/`. Without this, mempalace's `init` step in entrypoint-user.sh would download the model silently on first container start (suppressed via `>/dev/null 2>&1`), stalling startup by minutes on a fresh image. Pre-warming runs as `gosu developer` so the cache lands at the right path and is owned by the runtime user.
+- **Bugfix:** entrypoint-user.sh now redirects stdin from `/dev/null` for the `mempalace init --yes` call. Without this, the interactive `Mine this directory now? [Y/n]` prompt at the end of init would silently block forever when the container was started with `docker run -it` (TTY keeps stdin open). EOF on stdin makes the prompt fall through to its default.
+- **Smoke-test:** New `--variant with-pi` (threshold 2700 MB) and `--variant omos-with-pi` (3400 MB). Pi-specific assertions verify pi binary, pi-toolkit clone, pi-extensions clone, deployed keybindings symlink, extension count ≥ 4, mempalace bridge symlink, and settings.json bootstrap. Pi state assertions use `docker exec` from the host (not `run`-inside-container) since the container has no docker CLI.
+- **CI:** `.gitea/workflows/{validate,docker-publish}.yml` extended with `with-pi` and `omos-with-pi` matrix entries. Each release now produces eight Docker Hub tags: `vX.Y.Z[n]`, `latest`, `vX.Y.Z[n]-omos`, `latest-omos`, `vX.Y.Z[n]-with-pi`, `latest-with-pi`, `vX.Y.Z[n]-omos-with-pi`, `latest-omos-with-pi`.
+- **Docs:** README adds a "pi (alternative/complementary harness)" section. AGENTS.md codifies pi install contract, deploy ordering in entrypoint-user.sh, and rationale for not calling mempalace-toolkit's full `install.sh` from container.
+
+## v1.14.41 — 2026-05-08
+
+Bump opencode to 1.14.41.
+
+- **v1.14.41 (upstream):** restored formatter output handling for stdout/stderr writes; warping a session to another workspace can now carry over uncommitted file changes; restored custom provider setup in `/connect`; macOS Settings menu entry added; desktop local server split into a separate utility process; ACP clients restore last model/mode/effort when loading sessions and can close sessions cleanly.
+
+No container-level changes in this release. Dockerfile bump only.
+
+## v1.14.40 — 2026-05-07
+
+Bump opencode to 1.14.40.
+
+Rolls up upstream releases v1.14.34 → v1.14.40 (no v1.14.36). Highlights:
+
+- **v1.14.40:** support `.well-known/opencode` configs that point to a separate remote config file; assistant text preserved in signed reasoning blocks; CORS, network options, web terminal, and Cloudflare AI Gateway provider fixes; Mistral Medium 3.5 variants restored.
+- **v1.14.39:** desktop app respects `HTTP_PROXY` and friends; storage reads return `null` instead of failing when keys are missing.
+- **v1.14.38:** embedded UI requests work with arbitrary `connect-src` origins under the default CSP; desktop trusts system CA certificates for HTTPS.
+- **v1.14.37:** cancelling a task now cancels child subtask sessions; v2 session rendering improvements (cleaner tool states, better compaction summaries); new "warp a session into another workspace or back to local project" feature; Windows titlebar stable across zoom changes.
+- **v1.14.35:** preserve diff patch boundaries so session diffs render correctly when file contents themselves contain `diff --git` text.
+- **v1.14.34:** PTY connection tickets for authenticated terminal websockets; v2 session failure events for clients to detect failed runs; improved shell command handling for Bash/PowerShell/cmd; new `debug info` command; `--username` option for basic-auth server connections.
+
+No container-level changes in this release. Dockerfile bump only.
+
+## v1.14.33 — 2026-05-03
+
+**Bump opencode to 1.14.33. Named volume for opencode config, skillset auto-deploy, Context7 MCP.**
+
+Rolls up the image-structure changes originally planned for v1.14.32b onto the current opencode release. v1.14.32 was built but never deployed (wrong deploy dir caught the tag mid-flight); skipped in favor of landing everything together on 1.14.33.
+
+- **Breaking:** `~/.config/opencode/` now uses a named volume (`devbox-opencode-config`) instead of a host bind mount. The container's config, skills, and instructions are independent from the host. Users who relied on the bind mount should either re-add it explicitly in their compose file (overriding the volume) or migrate hand-edits into the container.
+- **Breaking:** `~/.agents/skills/` is no longer bind-mounted from the host. The container manages its own skills directory — the entrypoint deploys skills from the skillset repo on each start.
+- **Feature:** Skillset auto-deploy on container start. The entrypoint runs `deploy-skills.sh --bootstrap --prune-stale` from the first skillset repo found at: `$SKILLSET_CONTAINER_PATH` → `~/skillset` → `/workspace/skillset`. Creates relative symlinks that resolve inside the container regardless of host path layout. Idempotent.
+- **Feature:** Context7 remote MCP server registered in auto-generated config. No local binary; provides up-to-date library documentation to LLMs. Config file is now `opencode.jsonc` (supports comments) with a note about the optional API key for higher rate limits. Existing-config check detects both `.json` and `.jsonc`.
+- **Env:** New `SKILLSET_CONTAINER_PATH` env var for specifying skillset repo location inside the container when it's not at `/workspace/skillset`.
+- **Docs:** README updated for named volume config, skillset auto-deploy, Context7 MCP server, `opencode.jsonc` references. AGENTS.md, DOCKER_HUB.md regenerated.
+
+Upstream opencode 1.14.32 notes (shipped in this build since v1.14.32 was skipped): shell-mode input in the prompt is editable again (backspace, cursor keys); HTTP API workspace adapters no longer lose instance context, restoring workspace create/sync/routing; experimental workspace creation requests that omit `extra` are fixed; OpenAPI parameter schemas now match the public API so generated clients stop drifting; unsupported image formats fall back to text reads instead of being sent as image attachments; agents can use the global temp directory without extra permission prompts; Bedrock sessions that include reasoning content no longer break when switching models; session archive timestamps reject non-finite values to avoid invalid JSON. TUI: reduced startup theme flashing under the system theme, animated logo avoids subpixel rendering on terminals without truecolor support.

+Upstream opencode 1.14.33 release notes: see https://github.com/sst/opencode/releases/tag/v1.14.33.
+
+## v1.14.31d — 2026-05-01
+
+**CI: collapse per-arch matrix back into single multi-arch push jobs.**
+
+- **Fix:** `v1.14.31c`'s per-arch matrix build jobs failed on `Upload digest` with `GHESNotSupportedError: @actions/artifact v2.0.0+, upload-artifact@v4+ and download-artifact@v4+ are not currently supported on GHES`. Gitea Actions only implements the v3-compatible artifact API; `@v4` uses a GitHub-Enterprise-specific backend. Separately, `build-omos linux/arm64` hung silently for 12 minutes in "Set-up job" and then failed with no log output — likely catthehacker image-pull contention between concurrent matrix children on the same runner host.
+  - Rather than downgrade to `actions/{upload,download}-artifact@v3`, collapsed the per-arch matrix entirely. `docker/build-push-action@v7` with `platforms: linux/amd64,linux/arm64` publishes a proper multi-arch manifest in a single job, so the whole artifact-passing and `imagetools create` merge dance existed only to support a matrix split we no longer need.
+  - The original matrix split was designed around `load: true` disk exhaustion (v1.14.30b). With `push-by-digest`/`push: true` streaming straight to the registry — no local unpack — the peak disk story is fundamentally different. Validated in v1.14.31b that the reclaim step gives sufficient headroom for a single-job amd64 build; oracle-reviewed call that this should extend to the combined amd64+arm64 push case.
+  - Workflow goes from 7 jobs to 5 (smoke-base, smoke-omos, build-base, build-omos, update-description). 263 → ~110 lines of YAML in `docker-publish.yml`.
+- **Add:** `timeout-minutes: 90` on both build jobs so a hung arm64 build produces an explicit failure with logs rather than runner-default silent truncation.
+- **Add:** `BUILDKIT_PROGRESS=plain` at workflow level so arm64-under-QEMU build output is line-by-line (the default collapsed progress UI was obscuring earlier stalls).
+- **Add:** `AGENTS.md §CI quirks` documents the Gitea-specific traps encountered this week: `upload-artifact@v3`-only on Gitea, `/bin/sh` is dash, `build-push-action@v7` does multi-arch natively with comma-separated platforms, reclaim step is mandatory on `load: true` jobs.
+- No image changes. Rebuild of v1.14.31 content only.
+
+## v1.14.31c — 2026-05-01
+
+**CI: fix bash-specific parameter expansion and bump omos size threshold.**
+
+- **Fix:** `Derive platform slug` step in the per-arch matrix build jobs (`build-base`, `build-omos`) used `${PLATFORM_PAIR//\//-}` which is a bash parameter-expansion. The runner container executes step scripts via `/bin/sh` (dash), which errored with `Bad substitution`. Rewrote using `tr / -` which is POSIX and behaves identically. Both `build-base` and `build-omos` matrix jobs were blocked on this on `v1.14.31b`.
+- **Fix:** smoke-test image-size threshold for the `omos` variant bumped from 3000 MB to 3200 MB. The mempalace-toolkit bake-in added ~100 MB to omos; measured 3107 MB on `v1.14.31b`. All functional smoke checks (opencode, node, mempalace CLIs, toolkit wrappers, oh-my-opencode-slim) pass — this is a guardrail recalibration, not a performance concession. The underlying image genuinely grew.
+- The runner-disk reclaim step from v1.14.31b did its job: `smoke-base` and `validate-base` now pass cleanly. Only `smoke-omos` was blocked this iteration, and only on the threshold.
+- No image changes beyond what shipped in v1.14.31. Rebuild of v1.14.31 content only.
+
+## v1.14.31b — 2026-05-01
+
+**CI: reclaim runner disk before `load: true` smoke builds.**
+
+- **Fix:** v1.14.31's publish workflow and the `validate` workflow both hit `No space left on device` on the single-arch amd64 smoke/validate builds (`/opt/uv-tools/mempalace/lib/python3.13/site-packages/hf_xet/hf_xet.abi3.so`, `/usr/local/bin/git-lfs`). Root cause is not the build itself but the `load: true` step: peak disk during export equals tarball + unpacked image + buildx cache, and the image has crossed the ~3 GB threshold where this no longer fits in the ~12 GB of free space the runner container starts with. The v1.14.30c refactor split multi-arch into per-arch push-by-digest jobs (which don't `load`), but the smoke gates still do and still hit the wall.
+  - Added a `Reclaim runner disk` step to all four `load: true` jobs (`validate-base`, `validate-omos`, `smoke-base`, `smoke-omos`). The step strips `catthehacker/ubuntu:act-latest`-resident toolchains we never use (hosted-tool-cache, dotnet, android, powershell, swift, ghc, jvm, microsoft, chromium, boost) and runs `docker system prune -af --volumes` + `docker builder prune -af` against the runner's dockerd before `setup-buildx-action`. Expected reclaim is 6–12 GB depending on what's resident.
+  - Added workflow-level `concurrency: { group: ..., cancel-in-progress: false }` on `docker-publish.yml` so concurrent tag pushes can't race `docker system prune` in one job against an in-flight buildx cache in another.
+  - Pruning is deliberately kept out of the per-arch matrix push-by-digest jobs (`build-base`/`build-omos`) — those don't need it (no `load: true`), and pruning in parallel jobs risks one job nuking another's cache.
+- **Follow-up** (not in this release): image-size reduction via a dedicated `uv tool install mempalace` build stage (strips uv's cache from the final image), pinning `mempalace-toolkit` to a commit SHA with `--depth=1 --filter=blob:none`, and auditing whether `hf_xet` is actually required by mempalace at runtime. These will ship in the next release that rebases on a new opencode version.
+- No image changes. Rebuild of v1.14.31 content only.
+
+## v1.14.31 — 2026-05-01
+
+Bump opencode to 1.14.31.
+
+**CI infrastructure: split multi-arch publish across separate runners.**
+
+- **Fix:** The `publish` workflow exhausted runner disk space on `v1.14.30b` and would have hit the same wall on any subsequent release. Both variants built both architectures on a single `catthehacker/ubuntu:act-latest` container with ~40 GB of shared overlay space, and the peak disk footprint during the nodejs dpkg unpack / git-lfs layer export pushed it over the edge (`No space left on device`). The mempalace-toolkit bake-in from v1.14.30b added the final straw; the underlying issue is that QEMU-emulated arm64 layers were stored alongside the amd64 build on the same runner.
+  - `docker-publish.yml` refactored to the canonical `push-by-digest` + manifest-merge pattern: smoke test (amd64) runs on its own runner, each `(variant × arch)` push target runs on its own fresh runner with `outputs: type=image,...,push-by-digest=true,push=true` (no local image store), then a tiny merge job assembles the multi-arch manifest with `docker buildx imagetools create` from digest artifacts.
+  - Per-runner disk peak is now roughly one-quarter of the old single-job peak. The four Docker Hub tags produced per release (`vX.Y.Z[n]`, `latest`, `vX.Y.Z[n]-omos`, `latest-omos`) are unchanged.
+  - Also parallelizes the amd64 and arm64 builds, so wall-clock time for a release should drop noticeably despite the added merge hop.
+
+## v1.14.30b — 2026-04-30
+
+**Bake mempalace-toolkit wrappers into the image.**
+
+- **Fix:** The scheduler templates in [mempalace-toolkit's `contrib/`](https://gitea.jordbo.se/joakimp/mempalace-toolkit/src/branch/main/contrib) assume `mempalace-session` is available inside the container, but the image never actually installed it. Users following the `*-devbox` scheduler docs would silently lose the wrappers on every `docker compose up --force-recreate`, because the only way to get them was a post-hoc `./install.sh --yes` inside the container — which lives in the ephemeral layer. The host-side systemd timer would then fire, `docker exec` in, and hit `mempalace-session: command not found`. Caught during runtime validation on 2026-04-30.
+  - New Dockerfile block clones `mempalace-toolkit` at build time (depth-1) to `/opt/mempalace-toolkit/`, symlinks `bin/mempalace-session` and `bin/mempalace-docs` into `/usr/local/bin/`, and asserts both respond to `--help` before the layer succeeds.
+  - Gated by `ARG INSTALL_MEMPALACE_TOOLKIT=true` (defaults on, depends on `INSTALL_MEMPALACE=true`).
+  - Floated ref via `ARG MEMPALACE_TOOLKIT_REF=main` — override for reproducible builds once the toolkit starts tagging releases.
+- **Tests:** Smoke test gains three toolkit assertions (`mempalace-session --help`, `mempalace-docs --help`, symlink target check). The resolved-versions preamble now logs the toolkit git short-SHA alongside the other floated components.
+- **Docs:** README's MemPalace section gains a `Scheduled mining (mempalace-toolkit)` subsection covering the new wrappers and pointing at `contrib/` for scheduling. New build-args table entry for `INSTALL_MEMPALACE_TOOLKIT`.
+
+## v1.14.30 — 2026-04-30
+
+Bump opencode to 1.14.30.
+
+## v1.14.29c — 2026-04-29
+
+**Drop redundant mempalace-mcp-server wrapper, use the entry point mempalace ships.**
+
+- **Fix:** MCP integration with mempalace was still broken for users with custom `opencode.json` files because they typically had `["python3", "-m", "mempalace.mcp_server"]` from v1.14.28b and earlier. With the uv-tool install path, system python3 can't import mempalace and the MCP server subprocess exits immediately — opencode surfaced this as `MCP error -32000: connection closed`. Users should migrate to `["mempalace-mcp"]`. The auto-generated config in new containers already emits the new form.
+- **Cleanup:** Remove the hand-rolled `/usr/local/bin/mempalace-mcp-server` wrapper. The mempalace Python package ships a `mempalace-mcp` console entry point; `uv tool install` places it on PATH as a shim whose shebang points at the isolated venv's Python. The wrapper was duplicating what uv installs for free. Removed `rootfs/usr/local/bin/` and its COPY + chmod lines from the Dockerfile.
+- **Docs:** README's MemPalace section now shows `["mempalace-mcp"]` and explicitly warns against `["python3", "-m", "mempalace.mcp_server"]` with the observed failure mode.
+- **Tests:** Smoke test asserts `/usr/local/bin/mempalace-mcp` is executable and prints its symlink target, replacing the previous wrapper-present check.
+
+## v1.14.29b — 2026-04-29
+
+**Fix OMOS `bunx` detection + CI build reliability.**
+
+- **Fix:** `entrypoint-user.sh` checked `command -v bunx` to gate the OMOS auto-install, but the OMOS image only ships the `bun` binary — upstream's bun installer never creates a `bunx` symlink and neither did our Dockerfile. The check always failed on a fresh OMOS image, so `bun x oh-my-opencode-slim@latest install` never ran and first-start OMOS setup would have printed `ENABLE_OMOS=true but bun is not installed.` even though bun was right there. Latent until now because the only exercised path had a persisted `oh-my-opencode-slim.json` from a prior install.
+  - Changed the gate to `command -v bun`.
+  - Changed both install invocations from `bunx oh-my-opencode-slim@latest install ...` to `bun x oh-my-opencode-slim@latest install ...`.
+  - Added `ln -sf bun /usr/local/bin/bunx` to the Dockerfile's OMOS block so interactive users can still type `bunx` by habit, and verified the symlink at build time (`test -L /usr/local/bin/bunx`).
+  - Smoke test now asserts the `bunx` symlink is present on the OMOS variant.
+- **Fix:** CI build robustness against transient GitHub/Gitea CDN failures. The first attempt at building v1.14.29b tripped on a single HTTP 502 from GitHub's release CDN mid-download (`zoxide-0.9.9-x86_64-unknown-linux-musl.tar.gz`), failing the entire OMOS build with no retry. Fix applied to every tool-download curl in the Dockerfile:
+  - `curl --retry 5 --retry-delay 5 --retry-all-errors` on both the `-fsSL` GET requests and the `-sI` HEAD requests used for `/releases/latest` redirect resolution. 5 attempts with 5 s back-off eats most transient CDN hiccups without failing the build.
+  - Added `[ -n "$V" ]` assertion after each version-resolution step. If the HEAD redirect ever fails to produce a tag name, the build fails fast with an empty-version message rather than trying to download `.../v//...` and producing a confusing 404.
+  - Same hardening applied to the optional Go install block (go.dev JSON feed + tarball download) and the nodesource apt-repo setup script.
+- **Security:** Added `apt-get upgrade -y` to the core-packages RUN step. Picks up any security/CVE fixes published between `debian:trixie-slim` base-image rebuilds. Paired with the existing `update` and `install` in the same layer so image history isn't bloated. Today this produced `0 upgraded` (base image is current), but it future-proofs against the next CVE drop.
+
+## v1.14.29 — 2026-04-28
+
+**Opencode 1.14.29 + infrastructure and maintainability pass.**
+
+- Bump opencode to 1.14.29.
+- **Cleanup:** Remove dead `INSTALL_PYTHON` build arg. Python 3 + pip + venv have been unconditionally installed in the base layer since mempalace was added; the flag was a no-op. Users should use `uv` (pre-installed) or `uvx` for Python tooling.
+- **Fix:** `mempalace init` in `entrypoint-user.sh` now uses `--yes` for non-interactive operation. Previously the command prompted the user (`Your choice [enter/edit/add]:`) on first container start, which either hung or printed prompts into the user's terminal. The init is still gated by `[ ! -d "$PALACE_DIR/palace" ]` so existing palace data from prior versions is preserved untouched on upgrade.
+- **Feature:** MemPalace is now installed via `uv tool install` into an isolated venv at `/opt/uv-tools/mempalace/`, reached through a new `/usr/local/bin/mempalace-mcp-server` wrapper. Replaces the previous `pip install --break-system-packages` approach — removes the PEP 668 workaround and keeps mempalace deps out of system Python site-packages. The wrapper is what `generate-config.py` now references in the auto-generated `opencode.json`. Users with custom `opencode.json` files should update their mempalace MCP command from `["python3", "-m", "mempalace.mcp_server"]` to `["mempalace-mcp-server"]`.
+- **Feature:** New `INSTALL_MEMPALACE` build arg (default `true`). Rebuild with `--build-arg INSTALL_MEMPALACE=false` to shave ~300 MB off the image when local AI memory isn't needed.
+- **Refactor:** `opencode.json` generation extracted from `entrypoint-user.sh` into a standalone Python script at `/usr/local/lib/opencode-devbox/generate-config.py`. Easier to read, test, and extend with new providers. Default models are declared at the top of the script rather than hard-coded in bash heredocs. Reduces `entrypoint-user.sh` from 176 to 97 lines. Behavior is unchanged — the script preserves the critical guarantee of never overwriting an existing `opencode.json`.
+- **Perf:** Container startup avoids the recursive `chown -R` on named volumes that already have correct ownership. A `.devbox-owner` sentinel file written after a successful chown lets subsequent starts short-circuit via a single `cat`. On volumes with thousands of files (nvim plugins, palace data) this cuts multi-second startup costs to milliseconds. If `USER_UID` changes between runs, the sentinel mismatches and the full chown still runs.
+- **CI:** New `validate` workflow runs on every push to main and PR — single-arch amd64 build, smoke test, and DOCKER_HUB.md sync check. Catches broken Dockerfile changes without waiting for a tag push.
+- **CI:** `docker-publish.yml` now smoke-tests each variant on amd64 before the full multi-arch push. A failing smoke test blocks the release.
+- **CI:** Image size is tracked and fails the build if it exceeds thresholds (base: 2500 MB uncompressed, OMOS: 3000 MB). Makes bloat visible rather than silent.
+- **Docs:** `DOCKER_HUB.md` is now auto-generated from `README.md` via `scripts/generate-dockerhub-md.py`. Editing it directly is a mistake — the `--check` step in CI fails if the committed file is out of sync. Section inclusion is controlled by explicit rules (`SECTION_RULES`, `TRIM_SUBSECTIONS`); adding a new section to README forces an explicit keep/drop/replace decision. Keeps the 25 kB Docker Hub limit in sight and eliminates manual sync burden.
+- **Tests:** New `scripts/smoke-test.sh` asserts: (a) all core binaries are runnable and print a version, (b) opencode starts, (c) entrypoint correctly drops to the developer user, (d) `generate-config.py` produces valid JSON with the expected shape, (e) `generate-config.py` never overwrites an existing config, (f) bun is present only in the OMOS variant, (g) image size is under threshold. The smoke test also logs resolved versions of every component as its first step so CI output always records what got baked in.
+- **Versioning:** All GitHub/Gitea-hosted binaries (gosu, fzf, git-lfs, neovim, bat, eza, zoxide, uv, gitea-mcp) and the go.dev-hosted Go toolchain now default to `latest` at build time. Each `*_VERSION` ARG resolves the newest upstream release by reading the `/releases/latest` Location redirect (or the go.dev JSON feed). Previously these were hand-pinned to a specific version, which meant rebuilds didn't pick up upstream CVE fixes until someone remembered to bump the pin. Pinning is still supported — pass `--build-arg NVIM_VERSION=0.12.1` etc. to lock a specific version. Intentionally still pinned: `OPENCODE_VERSION` (drives the image tag), `NODE_VERSION=22` (major only), `DEBIAN_VERSION=trixie-slim` (OS base).
+
+## v1.14.28b — 2026-04-27
+
+- **Feature:** Add MemPalace local-first AI memory system to base image. Provides 29 MCP tools for semantic search over conversation history, knowledge graph queries, and agent diaries. Palace data persists via optional `devbox-palace` named volume, ChromaDB embedding model cache via `devbox-chroma-cache`. No API keys required.
+- **Feature:** Auto-register mempalace MCP server in generated opencode.json (when mempalace is installed and config is auto-generated from OPENCODE_PROVIDER).
+- **Feature:** Add official Gitea MCP server (`gitea-mcp`) to base image. Provides 50+ MCP tools for Gitea API (repos, issues, PRs, releases, Actions). Disabled by default — requires `GITEA_ACCESS_TOKEN` and `GITEA_HOST` env vars.
+
+## v1.14.28 — 2026-04-26
+
+Bump opencode to 1.14.28.
+
+## v1.14.25 — 2026-04-25
+
+Bump opencode to 1.14.25. Also includes container-level changes since v1.14.22b:
+- Add `python3-pip` and `python3-venv` to base image (fixes Mason LSP installs).
+- Add `devbox-nvim-data` named volume for neovim plugin/Mason persistence.
+- Add `devbox-zoxide` named volume for zoxide directory history persistence.
+- Bake devbox-shell bridge line into `/etc/skel-devbox/.bash_aliases`.
+- Add CHANGELOG.md with full release history.
+
+## v1.14.22b — 2026-04-23
+
+**Fix Mason LSP installs, persist nvim data, devbox-shell bridge.**
+
+- **Fix:** Add `python3-pip` and `python3-venv` to base image. Mason creates a Python venv per LSP package and pip-installs into it; Debian trixie ships python3 without ensurepip, so venv creation failed and every Mason Python package (ruff, ansible-lint) errored on every nvim start.
+- **Feature:** Add `devbox-nvim-data` named volume at `~/.local/share/nvim` — Lazy plugin cache and Mason LSP installs now persist across `--force-recreate`.
+- **Feature:** Add `devbox-zoxide` named volume at `~/.local/share/zoxide` — zoxide directory history persists across recreates.
+- **Feature:** Bake the devbox-shell bridge line into `/etc/skel-devbox/.bash_aliases` — hosts using the `~/.config/devbox-shell/` directory-mount pattern get automatic sourcing without manual setup after recreate.
+
+## v1.14.22 — 2026-04-23
+
+Bump opencode to 1.14.22.
+
+## v1.14.21 — 2026-04-23
+
+**Opencode 1.14.21 + zoxide persistence + multi-user fixes.**
+
+- Bump opencode to 1.14.21.
+- Fix single-file bind-mount caveat: document the kernel-level inode issue (affects all platforms, not just Docker Desktop).
+- Pin project name in default `docker-compose.yml` — directory renames no longer orphan named volumes.
+- Fix volume collision in shared-machine compose: scope project name by `SIGNUM`.
+- Auto-detect OS username (`$USER`) for volume isolation in own-account mode.
+- Document the upgrade ritual for reconciling VM compose files.
+- Add multi-user setup pointer in DOCKER_HUB.md.
+
+## v1.14.20b — 2026-04-21
+
+**Fix `[devbox]` prompt marker lost on `exec bash`.**
+
+- The PS1 prefix guard used an exported env var that survived `exec bash`, but PS1 itself doesn't — so the new shell skipped adding the prefix. Replaced with a substring check on PS1 itself.
+- Clarify tag-letter convention in AGENTS.md: suffix is the build ordinal, `a` is never used.
+
+## v1.14.20 — 2026-04-21
+
+**Opencode 1.14.20 + PROMPT_COMMAND/zoxide fix.**
+
+- Bump opencode to 1.14.20.
+- Fix `PROMPT_COMMAND` collision with zoxide: `history -a;` followed by zoxide's `;__zoxide_hook` produced `;;` which bash rejected on every prompt. Moved history-flush after zoxide init, using newline separator.
+- Includes all v1.14.19c shell-defaults work (baked `.bash_aliases`/`.inputrc` via `/etc/skel-devbox/`, skel-copy on first run, `devbox-shell-history` named volume).
+
+## v1.14.19d — 2026-04-21
+
+*Superseded by v1.14.20 before building. Tagged but never built.*
+
+## v1.14.19c — 2026-04-21
+
+**Bash history persistence, shell defaults, GID auto-detect.**
+
+- **Feature:** Bash history persists across `--force-recreate` via `devbox-shell-history` named volume at `~/.cache/bash`.
+- **Feature:** Quality-of-life shell defaults shipped in `/etc/skel-devbox/` and copied to `~/` only if absent: prefix history search on Up/Down, 100k-entry timestamped dedup history, coloured case-insensitive tab completion, eza/bat aliases, zoxide/fzf integrations, `[devbox]` prompt marker.
+- **Feature:** Skel-copy pattern — host bind-mounts and in-container customizations are never overwritten on upgrade.
+- **Fix:** Entrypoint now detects workspace UID and GID independently. Hosts with UID 1000 but non-1000 GID (e.g. Debian's `useradd` default GID 1001) get correct group remapping.
+- **Docs:** SSH banner-timeout troubleshooting (CGNAT), shell defaults section, skel restore/diff commands.
+
+## v1.14.19b — 2026-04-20
+
+**Ownership fixes and config/docs refresh.**
+
+- **Fix:** Root-owned parent dirs left behind by nested named-volume mounts. Entrypoint now chowns `.local`, `.local/share`, `.local/state`, `.config` before leaf mount points.
+- **Fix:** `deploy/sync-to-vm.sh` no longer preserves host GIDs (`rsync -a` → `-rlptDz`).
+- Default model IDs refreshed (claude-sonnet-4-6, gpt-5.4, global Bedrock inference profile).
+- Documentation gates oh-my-opencode-slim references to the OMOS variant.

+# opencode-devbox
 
 Portable AI developer environment for [opencode](https://opencode.ai). Debian-based, with git, SSH, Node.js, AWS CLI v2, and common dev tools pre-installed.
 
-## Image Variants
+Designed for teams who want a reproducible coding-agent setup that runs the same on every laptop and CI runner — without forcing each developer to install Bun, Node, AWS CLI, mempalace, or maintain shell config drift across machines.
 
-Two image variants are published for each release:
+## Image Variants
 
 | Tag | Description |
 |---|---|
 | `latest` / `vX.Y.Z` | Base image — opencode, Node.js, AWS CLI, dev tools |
 | `latest-omos` / `vX.Y.Z-omos` | Base + [oh-my-opencode-slim](https://github.com/alvinunreal/oh-my-opencode-slim) multi-agent orchestration and Bun |
+| `latest-with-pi` / `vX.Y.Z-with-pi` | Base + [pi](https://github.com/earendil-works/pi) as alternative/complementary harness (shares the mempalace install with opencode) |

 ## Quick Start
 
+For a fully-configured environment with persistent state (opencode config, mempalace memory, neovim plugins, bash history) surviving container recreation, use docker-compose. **You don't need to clone the repo** — just grab two template files:
+
+```bash
+mkdir -p ~/opencode-devbox && cd ~/opencode-devbox
+curl -O https://gitea.jordbo.se/joakimp/opencode-devbox/raw/branch/main/docker-compose.yml
+curl -fsSL https://gitea.jordbo.se/joakimp/opencode-devbox/raw/branch/main/.env.example -o .env
+# Edit .env — set OPENCODE_PROVIDER, the matching API key,
+# WORKSPACE_PATH, GIT_USER_NAME, GIT_USER_EMAIL.
+docker compose run --rm devbox
+```
+
+This drops you straight into opencode with your project mounted at `/workspace`. Use `bash` as the command (e.g. `docker compose run --rm devbox bash`) to land in a shell first — useful for `aws sso login`, `pi` (on `*-with-pi` variants), or multi-harness workflows.
+
+**One-shot run, no persistence:**
+
 ```bash
 docker run -it --rm \

-## Interactive Shell
+## What's Inside
 
-To get a shell first (useful for AWS SSO login or running other commands):
+- **[opencode](https://opencode.ai)** — primary coding-agent harness. Multi-provider (Anthropic, OpenAI, Bedrock, Google, Groq, etc.).
+- **[pi](https://github.com/earendil-works/pi)** *(in `*-with-pi` variants)* — lightweight TUI coding-agent that coexists with opencode and shares the same mempalace install. Includes the `mcp-loader` extension so any local-stdio or remote streamable-HTTP MCP server (searxng, gitea, context7, …) can be added by editing `~/.pi/agent/settings.json`.
+- **[mempalace](https://github.com/MemPalace/mempalace)** — persistent AI memory layer (ChromaDB + SQLite). Wing/diary/knowledge-graph entries are mutually visible to opencode and pi.
+- **[oh-my-opencode-slim](https://github.com/alvinunreal/oh-my-opencode-slim)** *(in `*-omos` variants)* — multi-agent orchestration on top of opencode (council, fallback chains, named agents).
+- **AWS CLI v2** with SSO support, **Node.js LTS**, **Bun** (OMOS variants), **uv** (Python), **gosu** for clean UID/GID adjustment to match your host workspace.
+- **MCP wrappers** for mempalace pre-installed and pre-wired to both harnesses.

+- **AWS Bedrock (SSO):** mount `~/.aws` from the host, `OPENCODE_PROVIDER=amazon-bedrock`, then `aws sso login` inside the container. Tokens persist across container restarts via the host bind-mount.
+- **OAuth / device-code providers:** auth state lives in opencode's config, which is persisted via the `devbox-opencode-config` named volume.
 
-Once opencode is running it takes over the terminal. To have a separate shell for `aws`, `git`, or other commands, run the container in the background and attach multiple times:
+Full Bedrock walkthrough (IAM roles, permissions, multi-account setups): see the [AWS Bedrock Authentication](
+https://gitea.jordbo.se/joakimp/opencode-devbox#aws-bedrock-authentication
+) section on gitea.
 
-```bash
-# Start in background
-docker run -d --name devbox \
-  -e ANTHROPIC_API_KEY=your-key \
-  -e OPENCODE_PROVIDER=anthropic \
-  -v ~/projects:/workspace \
-  -v ~/.ssh:/home/developer/.ssh:ro \
-  joakimp/opencode-devbox:latest sleep infinity
+## Persistence
 
-# Shell 1: run opencode
-docker exec -it -u developer devbox opencode
-
-# Shell 2 (separate terminal): aws, git, etc.
-docker exec -it -u developer devbox bash
-
-# When done
-docker rm -f devbox
-```
-
-> **Note:** Always use `-u developer` with `docker exec` — the container starts as root for UID adjustment, then drops to `developer`. Without `-u developer`, exec runs as root.
-
-## Environment Variables
-
-All configuration is done via environment variables, typically stored in a `.env` file.
-
-### Provider Configuration
-
-| Variable | Description | Default |
+| Volume | Mount | Survives |
 |---|---|---|
-| `OPENCODE_PROVIDER` | LLM provider (`anthropic`, `openai`, `amazon-bedrock`) | `anthropic` |
-| `OPENCODE_MODEL` | Model override | Provider default |
+| `devbox-opencode-config` | `~/.config/opencode` | container recreate, image rebuild |
+| `devbox-pi-config` | `~/.pi` | container recreate, image rebuild — incl. user-installed pi packages via `pi install` (`NPM_CONFIG_PREFIX` points into the volume) |
+| `devbox-palace` (uncomment) | `~/.mempalace` | container recreate, image rebuild — palace data is precious, treat as primary storage |
+| `devbox-chroma-cache` | `~/.cache/chroma` | container recreate (model cache, disposable — re-downloads in seconds) |
 
-### API Keys
+Workspace bind-mount (`/workspace`) is your project directory on the host, so source code is never inside the container.
 
-Set the key matching your provider:
+Full persistence reference, including multi-user (`SIGNUM`) isolation and host bind-mount alternatives: see the [README on gitea](https://gitea.jordbo.se/joakimp/opencode-devbox#persistence).
 
-| Variable | Provider |
-|---|---|
-| `ANTHROPIC_API_KEY` | Anthropic |
-| `OPENAI_API_KEY` | OpenAI |
-| `AWS_ACCESS_KEY_ID` + `AWS_SECRET_ACCESS_KEY` | AWS Bedrock (static creds) |

+## Sibling images
 
-### Git
+- **[`joakimp/pi-devbox`](https://hub.docker.com/r/joakimp/pi-devbox)** — pi-only image built on top of this image's base layer. Smaller (~700 MB) and version-tracks the [pi npm package](https://www.npmjs.com/package/@earendil-works/pi-coding-agent) directly. Use this if you want pi without opencode. Source: <https://gitea.jordbo.se/joakimp/pi-devbox>
 
-| Variable | Description |
-|---|---|
-| `GIT_USER_NAME` | Git commit author name |
-| `GIT_USER_EMAIL` | Git commit author email |
+## License
 
-### User ID Mapping
+MIT. See <https://gitea.jordbo.se/joakimp/opencode-devbox/src/branch/main/LICENSE>.
 
-The container runs as user `developer` (UID 1000 by default). If your host user has a different UID, file permission mismatches can occur on mounted volumes.
+---
 
-The entrypoint automatically detects the owner of `/workspace` and adjusts the container user's UID/GID to match. You can also set it explicitly:
-
-| Variable | Description | Default |
-|---|---|---|
-| `USER_UID` | Container user UID | Auto-detect from `/workspace` owner |
-| `USER_GID` | Container user GID | Auto-detect from `/workspace` owner |
-
-### Locale and Editor
-
-The container defaults to English (`en_US.UTF-8`) and neovim as the editor. Override via environment variables:
-
-| Variable | Description | Default |
-|---|---|---|
-| `LANG` | System locale | `en_US.UTF-8` |
-| `LANGUAGE` | Language priority list | `en_US:en` |
-| `LC_ALL` | Override all locale settings | `en_US.UTF-8` |
-| `EDITOR` | Default text editor | `nvim` |
-
-Pre-generated locales: `en_US`, `en_GB`, `sv_SE`, `da_DK`, `nb_NO`, `fi_FI`, `de_DE`, `fr_FR`, `es_ES`, `it_IT`, `pt_BR`, `nl_NL`, `pl_PL`, `ja_JP`, `ko_KR`, `zh_CN` (all UTF-8).
-
-Example for Swedish:
-
-```bash
-LANG=sv_SE.UTF-8
-LANGUAGE=sv_SE:sv
-LC_ALL=sv_SE.UTF-8
-```
-
-To add a locale not in the list, run inside the container:
-
-```bash
-sudo sed -i '/xx_XX.UTF-8/s/^# //g' /etc/locale.gen
-sudo locale-gen
-```
-
-Replace `xx_XX` with the desired locale (e.g. `ru_RU`, `tr_TR`). This change does not persist across container restarts — for permanent additions, build from source and modify the Dockerfile.
-
-## Initial Setup
-
-### 1. Create host directories
-
-Bind-mounted directories must exist on the host before starting the container. Docker creates missing directories as root-owned, which causes permission issues.
-
-```bash
-# Required
-mkdir -p ~/projects
-
-# If mounting opencode config (recommended for persistent settings)
-mkdir -p ~/.config/opencode
-
-# If using AWS Bedrock
-# mkdir -p ~/.aws
-
-# If mounting neovim config
-# mkdir -p ~/.config/nvim
-```
-
-### 2. Create a `.env` file
-
-Create a `.env` file with your configuration. Examples for each provider:
-
-**Anthropic:**
-```bash
-OPENCODE_PROVIDER=anthropic
-ANTHROPIC_API_KEY=sk-ant-...
-GIT_USER_NAME=Your Name
-GIT_USER_EMAIL=you@example.com
-```
-
-**OpenAI:**
-```bash
-OPENCODE_PROVIDER=openai
-OPENAI_API_KEY=sk-...
-GIT_USER_NAME=Your Name
-GIT_USER_EMAIL=you@example.com
-```
-
-**AWS Bedrock (SSO):**
-```bash
-OPENCODE_PROVIDER=amazon-bedrock
-OPENCODE_MODEL=amazon-bedrock/eu.anthropic.claude-opus-4-6-v1
-AWS_REGION=eu-west-1
-AWS_PROFILE=your-profile-name
-GIT_USER_NAME=Your Name
-GIT_USER_EMAIL=you@example.com
-```
-
-### 3. AWS SSO setup (Bedrock users only)
-
-AWS SSO requires a `~/.aws/config` file on the host with your SSO session configuration. If you already have this on another machine, copy it:
-
-```bash
-scp -r user@other-machine:~/.aws ~/.aws
-```
-
-Or configure from scratch:
-
-```bash
-aws configure sso
-```
-
-You'll be prompted for:
-- SSO session name
-- SSO start URL
-- SSO region
-- Registration scopes (typically `sso:account:access`)
-
-The `~/.aws` directory must be mounted into the container (see docker-compose example below).
-
-## Data Storage and Persistence
-
-Understanding what survives container restarts and what doesn't:
-
-| Path in container | Source | Survives restart? | Contains |
-|---|---|---|---|
-| `/workspace` | Host bind mount | ✅ Yes — lives on host | Your project files |
-| `/home/developer/.ssh` | Host bind mount (ro) | ✅ Yes — lives on host | SSH keys |
-| `/home/developer/.aws` | Host bind mount | ✅ Yes — lives on host | AWS credentials/SSO cache |
-| `/home/developer/.local/share/opencode` | Named volume (if configured) | ✅ Yes — Docker volume | Session history, memory, auth tokens |
-| `/home/developer/.local/share/uv` | Named volume (if configured) | ✅ Yes — Docker volume | Python installs, uv tool installs |
-| `/home/developer/.rustup` | Named volume (if configured) | ✅ Yes — Docker volume | Rust toolchains |
-| `/home/developer/.cargo` | Named volume (if configured) | ✅ Yes — Docker volume | Cargo binaries, registry cache |
-| `/home/developer/.vscode-server` | Named volume (if configured) | ✅ Yes — Docker volume | VS Code server and extensions |
-| `/home/developer/.config/opencode` | Host bind mount (if configured) | ✅ Yes — lives on host | opencode.json, oh-my-opencode-slim.json, skills |
-
-### Key points
-
-- **Project files** (`/workspace`) are always safe — they're your host filesystem.
-- **opencode config** is auto-generated from `OPENCODE_PROVIDER` env var on each start if no existing config is found. To persist config changes, mount the config directory from the host (see Custom opencode Config below).
-- **opencode data** (session history, memory) is lost with `--rm` unless you add a named volume.
-- **Python installs** via `uv python install` are lost unless you add the `devbox-uv` named volume.
-- **Rust toolchains** via `rustup-init` are lost unless you add the `devbox-rustup` and `devbox-cargo` named volumes.
-- **AWS SSO tokens** persist across restarts when `~/.aws` is mounted (recommended for Bedrock users).
-
-## Custom opencode Config
-
-For full control over opencode settings (MCP servers, custom models, oh-my-opencode-slim agents, etc.), mount the entire config directory from the host:
-
-```bash
-docker run -it --rm \
-  -v ~/.config/opencode:/home/developer/.config/opencode \
-  ... \
-  joakimp/opencode-devbox:latest
-```
-
-This persists all configuration changes across container restarts. When an existing `opencode.json` is found, the `OPENCODE_PROVIDER` auto-config is skipped.
-
-## Neovim Configuration
-
-The image includes neovim 0.12 with `EDITOR=nvim` set by default. To use your own neovim config (and have plugins auto-install via lazy.nvim on first start), mount it from the host:
-
-```bash
-docker run -it --rm \
-  -v ~/.config/nvim:/home/developer/.config/nvim:ro \
-  ... \
-  joakimp/opencode-devbox:latest
-```
-
-## Python Development with uv
-
-The image includes Python 3.13 (from Debian Trixie) and [uv](https://docs.astral.sh/uv/), a fast Python package manager that replaces pip, venv, and pyenv:
-
-```bash
-# Python 3.13 is available out of the box
-python3 --version
-
-# Use uv for package management
-uv venv
-uv pip install -r requirements.txt
-
-# Or use uv's project workflow (reads pyproject.toml)
-uv sync
-
-# Run a Python script
-uv run python script.py
-
-# Install standalone Python tools
-uvx ruff check .
-
-# Install a newer Python version (persists with devbox-uv volume)
-uv python install 3.14
-```
-
-To persist Python installs across container restarts, add a named volume:
-
-```bash
-docker run -it --rm \
-  -v devbox-uv:/home/developer/.local/share/uv \
-  ... \
-  joakimp/opencode-devbox:latest
-```
-
-Project virtual environments (`.venv`) are stored in your workspace directory and persist automatically via the `/workspace` bind mount.
-
-## Rust Development with rustup
-
-The image includes `rustup-init`, the Rust toolchain installer. Rust is not pre-installed but can be bootstrapped on demand:
-
-```bash
-# One-time setup: install Rust toolchain (~300MB, persists with volumes)
-rustup-init -y
-source ~/.cargo/env
-
-# Now use Rust normally
-cargo new my-project
-cargo build
-cargo run
-```
-
-To persist Rust toolchains and cargo data across container restarts, add named volumes:
-
-```bash
-docker run -it --rm \
-  -v devbox-rustup:/home/developer/.rustup \
-  -v devbox-cargo:/home/developer/.cargo \
-  ... \
-  joakimp/opencode-devbox:latest
-```
-
-## JavaScript and TypeScript
-
-The base image includes **Node.js 22** and **npm** — sufficient for most JavaScript and TypeScript development:
-
-```bash
-# Initialize a new project
-npm init -y
-
-# Install dependencies
-npm install
-
-# Run TypeScript (via tsx, ts-node, etc.)
-npx tsx src/index.ts
-```
-
-The OMOS image variant also includes **Bun**, a faster JavaScript runtime and package manager:
-
-```bash
-bun init
-bun install
-bun run src/index.ts
-```
-
-Node modules are stored in your project directory under `/workspace` and persist automatically.
-
-## VS Code Integration
-
-VS Code can connect directly to a running opencode-devbox container for a full IDE experience with IntelliSense, debugging, and extensions running inside the container.
-
-**Requirements:** Install the [Dev Containers](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) extension. For remote Docker hosts, also install [Remote - SSH](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-ssh).
-
-**Steps:**
-
-1. Start the container: `docker compose up -d`
-2. In VS Code: `Ctrl+Shift+P` → "Dev Containers: Attach to Running Container" → select `opencode-devbox`
-
-For remote Docker hosts (e.g. connecting to a server via SSH), first connect to the remote host with Remote-SSH, then attach to the container from there.
-
-VS Code extensions installed inside the container persist as long as the container exists. For persistent extension storage across container recreations, add a named volume:
-
-```bash
-docker run -it --rm \
-  -v devbox-vscode:/home/developer/.vscode-server \
-  ... \
-  joakimp/opencode-devbox:latest
-```
-
-## Using docker-compose
-
-Create a directory with a `docker-compose.yml` and a `.env` file:
-
-```bash
-mkdir opencode-devbox && cd opencode-devbox
-```
-
-`.env` — your settings (never commit this):
-
-```bash
-OPENCODE_PROVIDER=amazon-bedrock
-OPENCODE_MODEL=amazon-bedrock/eu.anthropic.claude-opus-4-6-v1
-AWS_REGION=eu-west-1
-AWS_PROFILE=your-profile-name
-GIT_USER_NAME=Your Name
-GIT_USER_EMAIL=you@example.com
-```
-
-`docker-compose.yml`:
-
-```yaml
-services:
-  devbox:
-    image: joakimp/opencode-devbox:latest
-    # For multi-agent orchestration, use the omos variant instead:
-    # image: joakimp/opencode-devbox:latest-omos
-    container_name: opencode-devbox
-    stdin_open: true
-    tty: true
-    env_file:
-      - .env
-    environment:
-      - TERM=xterm-256color
-    volumes:
-      - ~/projects:/workspace
-      - ~/.ssh:/home/developer/.ssh:ro
-      - devbox-data:/home/developer/.local/share/opencode
-      - devbox-uv:/home/developer/.local/share/uv
-      # Optional: persist Rust toolchains and cargo data
-      # - devbox-rustup:/home/developer/.rustup
-      # - devbox-cargo:/home/developer/.cargo
-      # Optional: persist VS Code server and extensions
-      # - devbox-vscode:/home/developer/.vscode-server
-      # Mount AWS config for Bedrock SSO (required for amazon-bedrock provider)
-      # - ~/.aws:/home/developer/.aws
-      # Optional: mount opencode config directory (persists config changes across restarts)
-      # - ~/.config/opencode:/home/developer/.config/opencode
-      # Optional: mount opencode agent skills from host
-      # - ~/.agents/skills:/home/developer/.agents/skills:ro
-      # Optional: mount neovim config from host (plugins auto-install on first start)
-      # - ~/.config/nvim:/home/developer/.config/nvim:ro
-
-volumes:
-  devbox-data:
-  devbox-uv:
-  # devbox-rustup:
-  # devbox-cargo:
-  # devbox-vscode:
-```
-
-Docker Compose loads `.env` automatically from the same directory. All variables from `.env` are passed to the container via `env_file`. Do **not** hardcode provider settings in the `environment:` section — use `.env` instead.
-
-Then:
-
-```bash
-# Start in background
-docker compose up -d
-
-# Open a shell (always use -u developer with exec)
-docker compose exec -u developer devbox bash
-
-# For Bedrock: authenticate, then start opencode
-aws sso login --sso-session <your-session> --use-device-code
-opencode
-
-# Or run opencode directly (if no SSO needed)
-docker compose exec -u developer devbox opencode
-
-# One-shot mode (creates and removes container)
-docker compose run --rm devbox        # direct to opencode
-docker compose run --rm devbox bash   # interactive shell
-```
-
-## What's Included
-
-### Base image (`latest`)
-
-- **Debian trixie-slim** — glibc, full terminal/PTY support
-- **opencode** — AI coding assistant
-- **Node.js 22** — for npx-based MCP servers
-- **AWS CLI v2** — SSO and Bedrock authentication
-- **Dev tools** — git, git-lfs, git-crypt, age, ssh, ripgrep, fd, fzf, bat, eza, zoxide, uv, rustup, jq, make, gcc, g++, curl, wget, neovim 0.12, tmux, htop, tree
-- **Non-root user** — runs as `developer` with UID auto-matched to workspace owner (sudo available)
-
-### OMOS image (`latest-omos`)
-
-Everything in the base image, plus:
-
-- **[oh-my-opencode-slim](https://github.com/alvinunreal/oh-my-opencode-slim)** — multi-agent orchestration plugin
-- **Bun** — JavaScript runtime required by oh-my-opencode-slim
-- **6 specialized agents** — Orchestrator, Explorer, Oracle, Librarian, Designer, Fixer
-
-### Additional runtimes (build from source)
-
-When [building from source](https://gitea.jordbo.se/joakimp/opencode-devbox), additional runtimes are available via build args:
-
-- **Python 3** (`INSTALL_PYTHON=true`) — Python 3 + pip + venv
-- **Go** (`INSTALL_GO=true`) — Go toolchain
-
-## oh-my-opencode-slim (OMOS variant)
-
-The `-omos` image variant includes [oh-my-opencode-slim](https://github.com/alvinunreal/oh-my-opencode-slim), which adds a multi-agent layer on top of opencode. An Orchestrator delegates tasks to specialized agents, each configurable with different models and providers.
-
-### Quick start with OMOS
-
-```bash
-docker run -it --rm \
-  -e OPENAI_API_KEY=your-key \
-  -e OPENCODE_PROVIDER=openai \
-  -e ENABLE_OMOS=true \
-  -v ~/projects:/workspace \
-  -v ~/.ssh:/home/developer/.ssh:ro \
-  joakimp/opencode-devbox:latest-omos
-```
-
-On first start, the entrypoint configures oh-my-opencode-slim automatically. The default preset uses OpenAI models.
-
-### OMOS environment variables
-
-| Variable | Default | Description |
-|---|---|---|
-| `ENABLE_OMOS` | `false` | Activate oh-my-opencode-slim on container start |
-| `OMOS_TMUX` | `false` | Enable tmux pane integration (watch agents in split panes) |
-| `OMOS_SKILLS` | `true` | Install recommended skills (simplify, agent-browser, cartography) |
-| `OMOS_RESET` | `false` | Force regenerate config on next start (backs up existing config) |
-
-### Custom OMOS configuration
-
-If you mount the opencode config directory (see Custom opencode Config above), the `oh-my-opencode-slim.json` file is included and persists across restarts. Edit it directly to control which models power each agent, fallback chains, council setup, and more.
-
-See the [oh-my-opencode-slim configuration docs](https://github.com/alvinunreal/oh-my-opencode-slim/blob/master/docs/configuration.md) for the full reference.
-
-### Verifying agents
-
-After starting opencode with OMOS enabled, run inside the opencode session:
-
-```
-ping all agents
-```
-
-All six agents should respond if your provider authentication is working.

+# opencode-devbox — base image (variant-independent layers)
+#
+# This Dockerfile produces an image tagged base-<hash>, used as the parent
+# for all four published variants (base, omos, with-pi, omos-with-pi).
+# It contains everything that does not depend on variant-specific
+# build-args (INSTALL_OPENCODE, INSTALL_OMOS, INSTALL_PI). The variant
+# Dockerfile (Dockerfile.variant) FROMs the base and adds only those
+# deltas.
+#
+# The base is rebuilt only when this file or anything it COPYs in
+# changes (rootfs/, entrypoint*.sh). Version bumps to OPENCODE_VERSION,
+# OMOS_VERSION, 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: 2026-05-14 (v1.14.50b — fresh apt + first promote-base-latest)

+curl -O https://gitea.jordbo.se/joakimp/opencode-devbox/raw/branch/main/docker-compose.yml

 ### Custom opencode config
 
-For full control over opencode settings (MCP servers, custom models, oh-my-opencode-slim agents, etc.), mount the entire config directory from the host:
+Opencode configuration is persisted automatically via the named volume `devbox-opencode-config`. This volume is mounted at `/home/developer/.config/opencode` by default — no host directory setup required. All changes to `opencode.jsonc`, skills, and (on the OMOS variant) `oh-my-opencode-slim.json` survive container recreation.
+
+When an existing `opencode.jsonc` is found in the volume, the `OPENCODE_PROVIDER` auto-config is skipped.
+
+**Alternative: host bind-mount** — if you specifically want to share config from the host (e.g. to version-control it or sync across machines), replace the named volume with a bind mount:
 
 ```yaml
 volumes:
   - ~/.config/opencode:/home/developer/.config/opencode
 ```
 
-This persists all configuration changes across container restarts, including `opencode.json`, `oh-my-opencode-slim.json`, and skills. When an existing `opencode.json` is found, the `OPENCODE_PROVIDER` auto-config is skipped.
+> **Portability note:** The mounted config runs inside a Linux container. Any absolute paths inside `opencode.jsonc` (for example, host-specific `plugin` entries like `file:///usr/local/lib/node_modules/...` or `file:///opt/homebrew/...`) will not resolve inside the container. Prefer bare package specifiers (e.g. `"oh-my-opencode-slim"`) that resolve via `node_modules` lookup, which works on both macOS and Linux hosts.
 
 ### Custom skills
 
-Mount agent skills from the host:
+Skills are deployed automatically from a skillset repo on container start. The entrypoint detects the skillset location in this order:
 
-```yaml
-volumes:
-  - ~/.agents/skills:/home/developer/.agents/skills:ro
-```
+1. `SKILLSET_CONTAINER_PATH` env var (explicit path to skillset repo inside container)
+2. `~/skillset` mount (if present)
+3. `/workspace/skillset` fallback (if your workspace contains a `skillset/` directory)
+
+When a skillset repo is detected, its skills are symlinked into `~/.agents/skills/` automatically. No manual configuration needed.
+
+> **Warning:** Do not bind-mount a host `~/.agents/skills` directory directly into the container. This conflicts with the symlink-based auto-deploy mechanism and causes broken skill references.

 All six agents should respond if your provider authentication is working.
 
+## pi (alternative/complementary harness)
+
+[pi](https://github.com/earendil-works/pi) is a lightweight TUI coding-agent that can run alongside opencode in the same container. Both harnesses share the mempalace install and palace data — wing/diary entries created by one are visible to the other.
+
+### Setup
+
+Pre-built pi-enabled images are available on Docker Hub as `joakimp/opencode-devbox:latest-with-pi` (base + pi) and `joakimp/opencode-devbox:latest-omos-with-pi` (OMOS + pi). Pulling one of those tags is the fastest path. Alternatively, build from source:
+
+### Build
+
+```bash
+docker compose build --build-arg INSTALL_PI=true
+# Or: pin a pi version
+docker compose build --build-arg INSTALL_PI=true --build-arg PI_VERSION=0.73.0
+# Or: pi-only image (no opencode, smaller)
+docker compose build --build-arg INSTALL_PI=true --build-arg INSTALL_OPENCODE=false
+```
+
+### Run
+
+The default `compose run --rm devbox` invocation drops to a login bash so you can choose:
+
+```bash
+docker compose run --rm devbox       # bash, then `pi` or `opencode` or `aws sso login`
+docker compose run --rm devbox pi     # launch pi directly
+docker compose run --rm devbox opencode
+```
+
+For an attached `compose up -d` container, both harnesses are reachable via `compose exec`:
+
+```bash
+docker compose exec -u developer devbox pi
+docker compose exec -u developer devbox opencode
+docker compose exec -u developer devbox bash
+```
+
+### What gets installed
+
+- **`pi` CLI** — npm-installed globally at build time. Version pinned by `PI_VERSION`.
+- **pi-toolkit** — keybindings.json (mosh/tmux newline fixes), pi-env.zsh (AWS env loader), settings.json template. Cloned to `/opt/pi-toolkit`; deployed to `~/.pi/agent/` on first container start.
+- **pi-extensions** — 7 extensions, cloned to `/opt/pi-extensions` and symlinked into `~/.pi/agent/extensions/`:
+  - `confirm-destructive` — confirm-prompt before dangerous bash commands and session actions.
+  - `ext-toggle` — `/ext` slash command to list and enable/disable extensions at runtime (rename-to-disable; survives `/reload`).
+  - `git-checkpoint` — per-turn `git stash` checkpoint, restorable on `/fork`.
+  - `mcp-loader` — generic MCP server loader. Reads an `mcp` block from `~/.pi/agent/settings.json` (same shape as opencode and Claude Desktop) and connects to each declared server, exposing the tools as native pi tools. Supports both **local stdio** subprocesses (`uvx mcp-searxng`, `gitea-mcp`, …) and **remote streamable-HTTP** servers per MCP spec 2025-03-26 (e.g. `https://mcp.context7.com/mcp`). Adds a `/mcp` slash command for runtime status / toggle (same UX as `/ext`). See [`pi-extensions/AGENTS.md`](https://gitea.jordbo.se/joakimp/pi-extensions/src/branch/main/AGENTS.md) for transport details and the `headers` config for auth tokens.
+  - `notify` — native terminal notification when the agent finishes.
+  - `ssh-controlmaster` — transparent SSH remote execution via persistent ControlMaster socket (when pi is launched with `--ssh user@host`).
+  - `todo` — `todo` tool for the agent + `/todos` for the user.
+- **mempalace bridge** — separate `mempalace.ts` extension symlinked from the cloned `mempalace-toolkit`. Provides pi's MCP tools for palace search/diary/knowledge-graph with bespoke agent-identity injection from `$MEMPALACE_AGENT_NAME`. Coexists with `mcp-loader` rather than replacing it — don't list `mempalace` in settings.json's `mcp` block too, or you'll get duplicate tool registrations.
+- **MCP servers (none baked in beyond mempalace)** — the loader registers nothing by default. Add servers by editing `~/.pi/agent/settings.json` and `/reload`. Examples (mcp-searxng for web search, context7 for live library docs) are in the `pi-extensions` README.

+`~/.pi/` is mounted on the `devbox-pi-config` named volume. Everything below survives container recreate **and** image rebuilds:
+
+- `~/.pi/agent/settings.json` (provider/model, theme selection, the `mcp` block, and the `packages` array tracking installed pi packages).
+- `~/.pi/agent/extensions/` (hand-placed extensions and the symlinks deployed by `pi-extensions/install.sh`).
+- `~/.pi/agent/sessions/`, `~/.pi/agent/auth.json`.
+- `~/.pi/agent/git/<host>/<path>/` (pi packages installed via `pi install git:...`).
+- `~/.pi/npm-global/` (pi packages installed via `pi install npm:...`, plus any `npm install -g` invoked as the `developer` user). `NPM_CONFIG_PREFIX` is pre-set in the image, the prefix's `bin/` is on `PATH`, and the directory itself lives on the volume — so user-installed themes, skills, and extensions survive everything short of `docker compose down -v`.
+
+The **baked** pi binary (and pi-toolkit / pi-extensions repos under `/opt/`) live on the image filesystem, not the volume. Image rebuild is the upgrade path for those — same contract as `OPENCODE_VERSION`. If you `npm install -g @earendil-works/pi-coding-agent` yourself, the user-installed copy on the volume wins via `PATH` order and survives image rebuilds.
+
+### Configuration
+
+The entrypoint copies `pi-toolkit/settings.example.json` to `~/.pi/agent/settings.json` on first start. Edit it to set provider/model:
+
+```bash
+docker compose exec -u developer devbox $EDITOR ~/.pi/agent/settings.json
+```
+
+The AWS env loader (`pi-env.zsh`) reads `~/.config/pi/.env` if you bind-mount one; otherwise pi uses container env vars passed via `.env`.

+## MemPalace — persistent AI memory
+
+The image includes [MemPalace](https://github.com/MemPalace/mempalace), a local-first AI memory system that stores conversation history verbatim and retrieves it via semantic search. Nothing leaves your machine.
+
+> MemPalace adds ~300 MB to the image (chromadb, embedding model deps). If you don't use it, rebuild with `--build-arg INSTALL_MEMPALACE=false` to shrink the image.
+
+### Enabling persistence
+
+Uncomment the palace volume in `docker-compose.yml`:
+
+```yaml
+- devbox-palace:/home/developer/.mempalace
+```
+
+Without the volume, palace data lives in the container's writable layer and is lost on `--force-recreate`.
+
+### MCP integration with opencode
+
+Add mempalace as an MCP server in your `opencode.jsonc` (inside `~/.config/opencode/`):
+
+```json
+{
+  "mcp": {
+    "mempalace": {
+      "type": "local",
+      "command": ["mempalace-mcp"]
+    }
+  }
+}
+```
+
+> The image installs mempalace into an isolated `uv tool` venv at `/opt/uv-tools/mempalace/`. `uv tool install` places `mempalace-mcp` on `PATH` as a shim whose shebang points at the venv's Python, so MCP clients can invoke it as a normal binary without worrying about the venv. Do **not** use `["python3", "-m", "mempalace.mcp_server"]` — the system Python cannot import from the uv-managed venv and you'll get `ModuleNotFoundError` / `MCP error -32000: connection closed`.
+
+This gives opencode access to 29 MCP tools for searching memory, querying the knowledge graph, managing wings/rooms/drawers, and agent diaries.
+
+### Basic usage
+
+```bash
+# Mine project files into the palace
+mempalace mine /workspace
+
+# Mine conversation transcripts
+mempalace mine ~/.local/share/opencode/ --mode convos
+
+# Search memory
+mempalace search "why did we switch to eno1"
+
+# Load context for a new session
+mempalace wake-up
+```
+
+Each workspace gets its own isolated "wing" — memories never leak between projects.
+
+### Scheduled mining (mempalace-toolkit)
+
+The image bakes in [mempalace-toolkit](https://gitea.jordbo.se/joakimp/mempalace-toolkit), a small set of bash wrappers that pair with mempalace for two common routines:
+
+```bash
+# Mine opencode session history (reads ~/.local/share/opencode/opencode.db, stages JSONL, mines into wing_conversations)
+mempalace-session
+
+# Mine a project's docs into a dedicated wing
+mempalace-docs /workspace/my-project
+```
+
+Both wrappers are idempotent and dedup-aware — re-running them on unchanged input is a cheap no-op.
+
+For weekly automated runs, the toolkit ships ready-to-use scheduler templates (systemd user timer, launchd user agent, cron) in its [`contrib/`](https://gitea.jordbo.se/joakimp/mempalace-toolkit/src/branch/main/contrib) directory. The `*-devbox` variants are designed for this container: host-side schedulers that `docker exec` into the running opencode-devbox.
+
+Disable the toolkit (keeps mempalace itself) with `--build-arg INSTALL_MEMPALACE_TOOLKIT=false`. Pin to a specific ref with `--build-arg MEMPALACE_TOOLKIT_REF=v0.3.0` once tagged releases exist.
+
+### Storage
+
+Two separate named volumes keep different data classes apart:
+
+- **Palace data** (`~/.mempalace/`): ChromaDB vectors, SQLite knowledge graph, drawers. This is your memory — back it up, treat it as precious. Persists via the `devbox-palace` named volume.
+- **Embedding model cache** (`~/.cache/chroma/`): ONNX model (~79 MB), downloaded automatically on first search. Disposable — blow it away and it re-downloads in ~4 seconds. Persists via the `devbox-chroma-cache` named volume so you don't re-download on every container recreation.
+- **No API keys required** for core functionality (local embeddings via ONNX).
+
+Both volumes are commented out by default in `docker-compose.yml` — uncomment to enable:
+
+```yaml
+- devbox-palace:/home/developer/.mempalace
+- devbox-chroma-cache:/home/developer/.cache/chroma
+```
+
+**Air-gapped environments:** pre-populate the `devbox-chroma-cache` volume with the `all-MiniLM-L6-v2/` model contents. The palace volume needs no pre-population.
+
+## Gitea MCP server
+
+The image includes the [official Gitea MCP server](https://gitea.com/gitea/gitea-mcp) (`gitea-mcp`), providing 50+ MCP tools for interacting with self-hosted Gitea instances — repositories, issues, pull requests, releases, branches, wiki, and Actions.
+
+### Setup
+
+1. Create a Personal Access Token on your Gitea instance (Settings → Applications → Generate Token, scopes: `repo`, `read:user`).
+
+2. Add to your `.env`:
+   ```env
+   GITEA_HOST=https://your-gitea-instance.example.com
+   GITEA_ACCESS_TOKEN=your_token_here
+   ```
+
+3. Enable the gitea MCP server in your `opencode.jsonc`:
+   ```json
+   {
+     "mcp": {
+       "gitea": {
+         "type": "local",
+         "command": ["gitea-mcp", "-t", "stdio", "--host", "{env:GITEA_HOST}"],
+         "environment": {
+           "GITEA_ACCESS_TOKEN": "{env:GITEA_ACCESS_TOKEN}"
+         },
+         "enabled": true
+       }
+     }
+   }
+   ```
+
+The server is installed but disabled by default — it requires authentication to be useful.
+
+## Context7 MCP server
+
+The image auto-registers a [Context7](https://context7.com) MCP server, which provides up-to-date library documentation and code examples to LLMs at query time. This is a remote MCP server at `mcp.context7.com/mcp` — no local binary is needed.
+
+- Auto-registered in the generated `opencode.jsonc` (no manual setup required)
+- Provides documentation for any programming library/framework on demand
+- Requires internet access — useless in air-gapped/offline environments
+
+## Shell defaults
+
+The image ships a baked `.bash_aliases` and `.inputrc` with quality-of-life defaults. On first container start they are copied from `/etc/skel-devbox/` into `/home/developer/` **only if the target file does not already exist** — so host bind-mounts and any version you've customized inside the container are never overwritten on upgrade.
+
+Defaults you get out of the box:
+
+- **Prefix history search** on Up/Down arrows (type `git `, press Up, walk back through prior `git ...` commands only). Ctrl-Up / Ctrl-Down still step through full history.
+- **Persistent history** — `$HISTFILE` points at `~/.cache/bash/history`, backed by the `devbox-shell-history` named volume so history survives container recreation. Timestamps, 100 000 entries, dedup.
+- **Case-insensitive tab completion**, coloured completion lists, `show-all-if-ambiguous`.
+- **Aliases** — `ls`/`ll`/`la` use `eza`, `cat` uses `bat`, `gs`/`gd`/`gl` for git, safe `rm`/`mv`/`cp`.
+- **Integrations** — `zoxide` (`z <fragment>` to jump), `fzf` Ctrl-R / Ctrl-T key bindings.
+- **Prompt marker** — `[devbox]` prefix so it's always obvious you're inside the container.
+
+### Overriding the defaults
+
+**Option A — bind-mount host files.** Uncomment the bind-mount lines in `docker-compose.yml`:
+
+```yaml
+- ~/.bash_aliases:/home/developer/.bash_aliases:ro
+- ~/.inputrc:/home/developer/.inputrc:ro
+```
+
+> **Single-file bind-mount caveat (all platforms):** Docker bind-mounts the file's **inode**, not its path. When editors like vim, nvim, VS Code, or `sed -i` save a file, they write to a temp file and `rename()` it over the original — creating a new inode. The container stays pinned to the old (now unlinked) inode and never sees the update. This is a kernel limitation ([Docker #15793](https://github.com/moby/moby/issues/15793)), not fixable by Docker. Append-only writes (`echo "alias foo=bar" >> file`) are safe because they modify the same inode. **Workaround:** mount the parent directory instead of the single file (e.g. `~/.config/devbox-shell:/home/developer/.config/devbox-shell:ro`) and source files from there.
+
+**Option B — customize inside the container.** Just edit `~/.bash_aliases` or `~/.inputrc` as normal. Pair this with a bind-mount or named volume on the home dir if you want the edits to survive container recreation.
+
+### Restoring or diffing defaults
+
+The skel files remain available inside every container at `/etc/skel-devbox/`. Useful commands:
+
+```bash
+# See what the image currently ships
+cat /etc/skel-devbox/.bash_aliases
+
+# Diff your current config against the upstream defaults
+diff ~/.bash_aliases /etc/skel-devbox/.bash_aliases
+
+# Reset to the baked defaults
+cp /etc/skel-devbox/.bash_aliases ~/.bash_aliases
+
+# …or delete the file and recreate the container — the entrypoint
+# copies from /etc/skel-devbox/ on next start if the target is absent
+rm ~/.bash_aliases
+```
+

 ```
 
 The script reads `docker-compose.yml` on the remote VM, detects which bind mounts are active, and syncs only those directories from your local machine. It also creates the remote directories if they don't exist.
+
+### Upgrading an existing VM to a new release
+
+Each tagged release may add new named volumes or bind-mount lines to `docker-compose.yml`. Pulling a new image via `docker compose pull` grabs the new container behaviour, but compose files on the VM are user-owned and never touched by the image — you have to reconcile them yourself when upgrading across versions.
+
+**Symptom of a missed reconcile:** a new feature quietly doesn't work even though the image is correct. Example from v1.14.19c → v1.14.20: bash history persistence requires the `devbox-shell-history` named volume mounted at `/home/developer/.cache/bash`. The v1.14.20 image writes history to that path either way, but without the volume mount on the VM, writes land in the container's writable layer and vanish on every `--force-recreate`.
+
+**Upgrade ritual:**
+
+```bash
+# On the VM, before recreating the container:
+cd ~/opencode-devbox
+cp docker-compose.yml docker-compose.yml.bak-$(date +%Y%m%d-%H%M%S)
+
+# Compare against the repo version to see what's new:
+#   (from your local checkout)
+scp devbox-affection:~/opencode-devbox/docker-compose.yml /tmp/vm-compose.yml
+diff -u /tmp/vm-compose.yml ~/src/src_local/opencode-devbox/docker-compose.yml
+```
+
+For each new `volumes:` entry or mount line in the repo version that isn't in your VM's file, add it manually — preserving any local customizations you've made (image variant, read/write flags on bind mounts, etc.). Then:
+
+```bash
+docker compose config >/dev/null   # verify YAML still parses
+docker compose up -d --force-recreate
+```
+
+If you maintain the VM's compose file with no local changes, `scp` the repo version over wholesale. If you have customizations (the common case), do the diff-and-merge by hand.
+
+### Shell defaults inside the container
+
+The image ships baked `.bash_aliases` and `.inputrc` in `/etc/skel-devbox/` — quality-of-life defaults (prefix history search on Up/Down arrows, persistent history across container recreates via the `devbox-shell-history` named volume, `[devbox]` prompt marker, sensible aliases). On first container start the entrypoint copies them to `/home/developer/` **only if the target file does not already exist**.
+
+This means:
+
+- Fresh containers get the defaults automatically.
+- If you bind-mount your host's `~/.bash_aliases` / `~/.inputrc` (see the commented lines in `docker-compose.yml`), your host versions win.
+- If you edit the files inside a running container and store them via a home-dir bind-mount or equivalent, subsequent upgrades never overwrite them.
+- To restore the baked defaults any time: `cp /etc/skel-devbox/.bash_aliases ~/` (or delete the file and recreate the container).
+- To diff your current config against what the image ships: `diff ~/.bash_aliases /etc/skel-devbox/.bash_aliases`.
+
+### CI runner maintenance: automatic Docker pruning
+
+Gitea Actions runners accumulate Docker build cache, stale buildkit containers, and unused images over time. Without periodic cleanup, the runner's disk fills up and builds stall during the image-push phase (symptom: `#61 exporting to image` / `pushing layers` hangs indefinitely while buildkit repeatedly re-authenticates with Docker Hub).
+
+Set up two layers of automatic cleanup on the runner host:
+
+**1. Daily cron job** — prunes images, containers, and build cache older than 72 hours:
+
+```bash
+sudo tee /etc/cron.daily/docker-prune <<'EOF'
+#!/bin/sh
+docker system prune -af --filter "until=72h" > /var/log/docker-prune.log 2>&1
+docker builder prune -af --filter "until=72h" >> /var/log/docker-prune.log 2>&1
+EOF
+sudo chmod +x /etc/cron.daily/docker-prune
+```
+
+**2. Docker daemon builder GC** — caps buildkit cache at 10 GB (Docker 23.0+):
+
+Add to `/etc/docker/daemon.json` (create if absent):
+
+```json
+{
+  "builder": {
+    "gc": {
+      "enabled": true,
+      "defaultKeepStorage": "10GB"
+    }
+  }
+}
+```
+
+Then `sudo systemctl restart docker`.
+
+Both are safe to run on a machine that also hosts long-running containers (like opencode-devbox) — `docker system prune` only removes *unused* images and *stopped* containers, never running ones.
+
+### Troubleshooting: SSH hangs or "banner exchange" timeouts
+
+If SSH to the VM intermittently fails with `Connection timed out during banner exchange` or pure TCP connect timeouts — especially after the first few successful connects in a short window — the cause is almost certainly your ISP's CGNAT (Carrier-Grade NAT), not the VM.
+
+**Symptoms**
+
+- First 3–4 SSH connects succeed, then subsequent ones fail hard for 20–30 minutes
+- `ping` to the VM works perfectly throughout (ICMP isn't tracked the same way)
+- `mosh` sessions stay stable once established (UDP, different flow table)
+- Happens on residential ISPs (Tele2, Comhem, Telia, most European consumer broadband)
+- VM-side logs show SSH is idle — the SYNs never reach it
+
+**Cause**
+
+Residential CGNAT boxes keep a per-subscriber TCP flow table with a small concurrent-flow cap (~4) per destination IP. Once exhausted, new SYNs to that destination are silently dropped until old flows age out (typically 20–30 min after TCP close).
+
+**Fix**
+
+Add SSH connection multiplexing on your client so all SSH sessions (interactive, `scp`, `rsync`, scripts) share a single TCP connection to the VM:
+
+```ssh-config
+# ~/.ssh/config
+Host <vm-alias>
+    HostName <vm-ip>
+    User devbox
+    IdentityFile ~/.ssh/id_ed25519
+    ControlMaster auto
+    ControlPath ~/.ssh/cm/%r@%h:%p
+    ControlPersist 4h
+    ServerAliveInterval 30
+    ServerAliveCountMax 6
+```
+
+Then create the socket directory:
+
+```bash
+mkdir -p ~/.ssh/cm && chmod 700 ~/.ssh/cm
+```
+
+All SSH to the VM now multiplexes over a single flow slot, regardless of how many parallel sessions you open. `sync-to-vm.sh` already does this internally for its own rsync/scp calls.
+
+For a more robust long-term fix (especially if you access the VM from multiple hosts), run a WireGuard tunnel on the VM and route SSH through that — UDP bypasses the TCP flow table entirely.

+Generate DOCKER_HUB.md.
+
+Rationale
+---------
+DOCKER_HUB.md is the public-facing description shown on Docker Hub. It
+has two hard constraints the README does not:
+
+  1. A 25 kB byte limit on the full_description field.
+  2. A different audience: Hub readers want a 30-second evaluation —
+     "what is this, how do I run it, does it have what I need" — and
+     reference material is better consulted in context on gitea.
+
+For a long time this script tried to derive DOCKER_HUB.md from README.md
+by section selection + targeted replacement. As the README grew that
+approach pushed against the 25 kB ceiling on every change, costing a
+trim-something-else exercise per edit (final state: 3 byte headroom).
+
+The new approach is much simpler: a hand-written HUB_TEMPLATE below.
+The template intentionally stays slim and links out to the gitea README
+for everything that benefits from depth. README.md grows freely.
+
+Trade-off: when image-variants table or quick-start flow changes,
+update HUB_TEMPLATE here too. That coupling is now explicit and
+local rather than spread across SECTION_RULES + REPLACEMENTS + TRIM
+machinery.
+
+Usage
+-----
+Regenerate in place:
+    python3 scripts/generate-dockerhub-md.py
+
+Fail if DOCKER_HUB.md is out of sync with what this script would emit

+
+Portable AI developer environment for [opencode](https://opencode.ai). Debian-based, with git, SSH, Node.js, AWS CLI v2, and common dev tools pre-installed.

+Designed for teams who want a reproducible coding-agent setup that runs the same on every laptop and CI runner — without forcing each developer to install Bun, Node, AWS CLI, mempalace, or maintain shell config drift across machines.
+
+## Image Variants
+
+| Tag | Description |
+|---|---|
+| `latest` / `vX.Y.Z` | Base image — opencode, Node.js, AWS CLI, dev tools |
+| `latest-omos` / `vX.Y.Z-omos` | Base + [oh-my-opencode-slim](https://github.com/alvinunreal/oh-my-opencode-slim) multi-agent orchestration and Bun |
+| `latest-with-pi` / `vX.Y.Z-with-pi` | Base + [pi](https://github.com/earendil-works/pi) as alternative/complementary harness (shares the mempalace install with opencode) |
+| `latest-omos-with-pi` / `vX.Y.Z-omos-with-pi` | OMOS + pi together |
+
+All variants support `linux/amd64` and `linux/arm64`.
+
+## Quick Start
+
+For a fully-configured environment with persistent state (opencode config, mempalace memory, neovim plugins, bash history) surviving container recreation, use docker-compose. **You don't need to clone the repo** — just grab two template files:
+
+```bash
+mkdir -p ~/opencode-devbox && cd ~/opencode-devbox
+curl -O https://gitea.jordbo.se/joakimp/opencode-devbox/raw/branch/main/docker-compose.yml
+curl -fsSL https://gitea.jordbo.se/joakimp/opencode-devbox/raw/branch/main/.env.example -o .env
+# Edit .env — set OPENCODE_PROVIDER, the matching API key,
+# WORKSPACE_PATH, GIT_USER_NAME, GIT_USER_EMAIL.
+docker compose run --rm devbox
+```
+
+This drops you straight into opencode with your project mounted at `/workspace`. Use `bash` as the command (e.g. `docker compose run --rm devbox bash`) to land in a shell first — useful for `aws sso login`, `pi` (on `*-with-pi` variants), or multi-harness workflows.
+
+**One-shot run, no persistence:**
+
+```bash
+docker run -it --rm \\
+  -e ANTHROPIC_API_KEY=your-key \\
+  -e OPENCODE_PROVIDER=anthropic \\
+  -e GIT_USER_NAME="Your Name" \\
+  -e GIT_USER_EMAIL="you@example.com" \\
+  -v ~/projects:/workspace \\
+  -v ~/.ssh:/home/developer/.ssh:ro \\
+  joakimp/opencode-devbox:latest
+```
+
+Full setup guide — authentication for each provider (Anthropic, OpenAI, Bedrock SSO + static), persistence model, build args, troubleshooting: <{GITEA}#readme>
+
+## What's Inside
+
+- **[opencode](https://opencode.ai)** — primary coding-agent harness. Multi-provider (Anthropic, OpenAI, Bedrock, Google, Groq, etc.).
+- **[pi](https://github.com/earendil-works/pi)** *(in `*-with-pi` variants)* — lightweight TUI coding-agent that coexists with opencode and shares the same mempalace install. Includes the `mcp-loader` extension so any local-stdio or remote streamable-HTTP MCP server (searxng, gitea, context7, …) can be added by editing `~/.pi/agent/settings.json`.
+- **[mempalace](https://github.com/MemPalace/mempalace)** — persistent AI memory layer (ChromaDB + SQLite). Wing/diary/knowledge-graph entries are mutually visible to opencode and pi.
+- **[oh-my-opencode-slim](https://github.com/alvinunreal/oh-my-opencode-slim)** *(in `*-omos` variants)* — multi-agent orchestration on top of opencode (council, fallback chains, named agents).
+- **AWS CLI v2** with SSO support, **Node.js LTS**, **Bun** (OMOS variants), **uv** (Python), **gosu** for clean UID/GID adjustment to match your host workspace.
+- **MCP wrappers** for mempalace pre-installed and pre-wired to both harnesses.
+
+## Authentication
+
+The container reads provider credentials from environment variables and host-mounted config:
+
+- **Anthropic / OpenAI / Groq / others:** set `OPENCODE_PROVIDER` and the corresponding `*_API_KEY` via `-e` or `.env`.
+- **AWS Bedrock (SSO):** mount `~/.aws` from the host, `OPENCODE_PROVIDER=amazon-bedrock`, then `aws sso login` inside the container. Tokens persist across container restarts via the host bind-mount.
+- **OAuth / device-code providers:** auth state lives in opencode's config, which is persisted via the `devbox-opencode-config` named volume.
+
+Full Bedrock walkthrough (IAM roles, permissions, multi-account setups): see the [AWS Bedrock Authentication](
+{GITEA}#aws-bedrock-authentication
+) section on gitea.
+
+## Persistence
+
+| Volume | Mount | Survives |
+|---|---|---|
+| `devbox-opencode-config` | `~/.config/opencode` | container recreate, image rebuild |
+| `devbox-pi-config` | `~/.pi` | container recreate, image rebuild — incl. user-installed pi packages via `pi install` (`NPM_CONFIG_PREFIX` points into the volume) |
+| `devbox-palace` (uncomment) | `~/.mempalace` | container recreate, image rebuild — palace data is precious, treat as primary storage |
+| `devbox-chroma-cache` | `~/.cache/chroma` | container recreate (model cache, disposable — re-downloads in seconds) |
+
+Workspace bind-mount (`/workspace`) is your project directory on the host, so source code is never inside the container.
+
+Full persistence reference, including multi-user (`SIGNUM`) isolation and host bind-mount alternatives: see the [README on gitea]({GITEA}#persistence).
+
+## Where to Go Next
+
+- **Full README** with build args, every feature in detail, troubleshooting: <{GITEA}>
+- **CHANGELOG** for version history: <{GITEA}/src/branch/main/CHANGELOG.md>
+- **Issues / source / docker-compose templates:** <{GITEA}>
+- **Agent-facing internals** (for future maintainers / coding agents working in the repo): <{GITEA}/src/branch/main/AGENTS.md>
+
+## Sibling images
+
+- **[`joakimp/pi-devbox`](https://hub.docker.com/r/joakimp/pi-devbox)** — pi-only image built on top of this image's base layer. Smaller (~700 MB) and version-tracks the [pi npm package](https://www.npmjs.com/package/@earendil-works/pi-coding-agent) directly. Use this if you want pi without opencode.
