Cut v1.15.13b — LAN access + fork/recall + pi-only variant

Container-level rebuild on opencode 1.15.13 / pi 0.78.0 (both unchanged):
host-OS-agnostic LAN access (base), pi-fork (fork) + pi-observational-memory
(recall) in pi variants, and the new pi-only variant (basis for pi-devbox).

 ## 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).
+opencode-devbox publishes **five image variants** (`base`, `omos`, `with-pi`, `omos-with-pi`, `pi-only`) × **two architectures** (amd64, arm64) = **ten 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.

 - `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.
+- `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. When `INSTALL_PI=true` it also clones `pi-fork` + `pi-observational-memory` (from `github.com/elpapi42`, refs `PI_FORK_REF`/`PI_OBSMEM_REF`) to `/opt` and runs `npm install` there at build time so the `fork`/`recall` extensions can load (a local-path `pi install` does not npm-install). The `pi-only` variant sets `INSTALL_OPENCODE=false`, `INSTALL_PI=true` — pi without opencode, the single source of truth for the separate `pi-devbox` image.
 - `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.
+- `entrypoint-user.sh` — runs as developer: git config, opencode.jsonc generation (delegated to `generate-config.py`), LAN-access setup (delegated to `setup-lan-access.sh`), pi-toolkit + pi-extensions deploy (when pi installed), pi settings.json bootstrap, mempalace pi-bridge symlink, runtime `pi install /opt/{pi-fork,pi-observational-memory}` registration (idempotent), skillset auto-deploy from mounted skillset repo, OMOS setup.
+- `rootfs/usr/local/lib/opencode-devbox/setup-lan-access.sh` — host-OS-agnostic LAN reachability helper. Detects VM-backed hosts (macOS OrbStack / Docker Desktop, via `host.docker.internal` resolution) and generates a writable `~/.ssh-local/config` using the host as an SSH jump; no-op on native Linux. Controlled by `DEVBOX_LAN_ACCESS` / `HOST_SSH_USER` / `DEVBOX_HOST_ALIAS`. Ships the mechanism only (generic `host` jump alias); user targets stay in their bind-mounted `~/.ssh/config`. Non-fatal. Counted in the base hash, so editing it advances `base-latest`.
 - `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).

 - **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.
+- **Pre-flight check before cutting any non-letter-suffixed tag** — verify the bump is real:
+  ```bash
+  npm view opencode-ai version           # must equal the X.Y.Z in your tag
+  ```
+  If the npm version equals the *previous* release's `X.Y.Z`, you're cutting a letter-suffix rebuild (`vX.Y.Zc`, `vX.Y.Zd`, …), not a new minor. **A bare `vX.Y.Z` tag is a claim that opencode upstream just released `X.Y.Z`** — if that claim is wrong, future opencode releases will collide with your tag namespace and the version-tracking story breaks.
+  
+  Cautionary example: 2026-05-28 morning, `v1.15.12` was cut while opencode-ai was still at `1.15.11`. The commit message itself acknowledged "OPENCODE_VERSION stays at 1.15.11" but tagged `v1.15.12` anyway. Re-cut as `v1.15.11c` the same afternoon (see CHANGELOG). The `v1.15.12` git tag and Hub images stayed as historical artifacts; the slip cost a CI cycle and a CHANGELOG-rewrite. **Run the npm view check at the top of every release-day cut.**
 
-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.
+CI produces ten 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`, `vX.Y.Z[n]-pi-only`, `latest-pi-only` — one tag pair (versioned + floating alias) per build variant (five variants).
 
 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.

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`.
 - **`PI_VERSION` and `OMOS_VERSION` MUST be passed by CI as concrete versions**, not left at the `latest` default. The npm install steps in `Dockerfile.variant` (`npm install -g @earendil-works/pi-coding-agent` / `oh-my-opencode-slim@${OMOS_VERSION}`) produce identical layer-hashes when the ARG values are byte-identical across builds; combined with the registry buildcache (`base-buildcache`) the layer gets reused even when `latest` would have resolved to a newer upstream. This is the same class of bug that bit pi-devbox v0.74.0 → v0.75.5 (silent same-bytes-across-releases regression discovered 2026-05-23, fixed in pi-devbox v0.75.5b). It is currently *masked* in opencode-devbox by `OPENCODE_VERSION` being a hard-coded ARG that bumps every release — that bump invalidates the parent-chain cache key for the downstream pi/omos layers — but the masking would fail the moment a `vN.N.Nb` opencode-version-unchanged release ships that only bumps pi or omos. Preventative fix: `.gitea/workflows/docker-publish-split.yml` has a `resolve-versions` job that runs `npm view @earendil-works/pi-coding-agent version` and `npm view oh-my-opencode-slim version`, exposing concrete values as outputs that every variant smoke + build job consumes via build-args. Smoke tests assert via `EXPECTED_PI_VERSION` / `EXPECTED_OMOS_VERSION` env vars — would catch the regression on the next release rather than four releases later. **If you change the variant build-args list, the resolve-versions job, or the smoke EXPECTED_*_VERSION wiring, audit all affected jobs in lockstep.**
+- **Registry buildkit cache-export is currently disabled** — do NOT re-add `cache-from`/`cache-to` to the `build-base` step in `.gitea/workflows/docker-publish-split.yml` without first verifying that buildkit's `mode=max` cache-export to `registry-1.docker.io` no longer returns HTTP 400 from the Hub CDN edge. The regression surfaced ~2026-05-23 and broke five consecutive opencode-devbox publish attempts (runs #332/333/334/336 + a rerun); root-caused on 2026-05-28 by a manual host-side publish that reproduced the same 400 only on `--cache-to` while image push worked fine. Failure shape is stable (`Offset:0` in the `_state` token, HTML response body = CDN-tier rejection, not registry backend), repo-specific (we're the only repo writing `:base-buildcache` mode=max), and explains why pinning `setup-buildx-action@v4.0.0` didn't help (action pin doesn't change the bundled buildkit version on the catthehacker runner image). Trade-off: dockerfile.base changes pay a full ~3 min rebuild instead of pulling cached layers; unchanged bases short-circuit at the Hub-probe step in `base-decide` and never re-build anyway. Variants don't use registry cache so they're unaffected. Re-enable condition: upstream moby/buildkit fix lands AND a low-risk test run succeeds without 400s. See CHANGELOG v1.15.12 `Unreleased` block for the full diagnostic chain. Manual escape-hatch publish procedure: `docs/manual-host-publish.md`.
+- **Push steps wrap `docker buildx build --push` in a 3-attempt retry loop** (15s, 30s backoff) for transient `registry-1.docker.io` blips — rate limits, brief 5xx, CDN flap. Implemented as inline `shell: bash` steps with `docker buildx build` raw rather than `docker/build-push-action@v7` so the loop is visible and tweakable. Affects the 1 base + 5 variant push steps in `.gitea/workflows/docker-publish-split.yml`; smoke-test builds (`load: true`, no push) are untouched. **This does NOT mask deterministic failures** — a true regression (like the cache-export 400 of 2026-05-23..28) fails all 3 attempts identically and the job still fails. Orthogonal to the cache-export disablement above: cache-export was about a deterministic protocol mismatch, retry is about absorbing genuine transients. Both are belt-and-braces with the `ci-release-watcher` skill's transient-rerun heuristic. If you change the matrix of push steps, keep the retry wrapper consistent across them — the pattern is duplicated rather than factored out because Gitea Actions doesn't support reusable composite shell steps cleanly.
 - **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.

+## v1.15.13b — 2026-06-03
+
+Container-level rebuild on opencode `1.15.13` (unchanged) and pi `0.78.0` (unchanged) — adds host-OS-agnostic LAN access, the `fork`/`recall` pi extensions, and a new `pi-only` variant. Letter-suffix release per the `v{opencode_version}[letter]` scheme since no upstream version moved.
+
+### Added: host-OS-agnostic LAN access (base image)
+
+The container can now reach LAN peers that the **host** can reach, regardless of host OS — addressing the macOS/Docker-Desktop limitation where a container in the Linux VM cannot see the host's directly-attached LAN.
+
+- New `rootfs/usr/local/lib/opencode-devbox/setup-lan-access.sh`, invoked (non-fatally) by `entrypoint-user.sh` on every start.
+- **Detection:** on VM-backed hosts (macOS OrbStack / Docker Desktop, Windows Docker Desktop — detected via `host.docker.internal` resolution) it generates a writable `~/.ssh-local/config` that uses the host as an SSH **jump**. On native Linux Docker (LAN reachable directly) it is a **no-op**.
+- **Mechanism, not policy:** ships a generic `host` (alias `mac`) jump entry + a generated jump key in the writable `~/.ssh-local/` sidecar (necessary because `~/.ssh` is bind-mounted read-only). Your own targets stay in your bind-mounted `~/.ssh/config` (add `ProxyJump host`), pulled in via `Include ~/.ssh/config`.
+- New env knobs: `DEVBOX_LAN_ACCESS` (`auto`|`jump`|`off`, default `auto`), `HOST_SSH_USER`, `DEVBOX_HOST_ALIAS`. When `HOST_SSH_USER` is unset the entrypoint prints the public key to authorize on the host.
+- New `dssh` / `dscp` aliases in `.bash_aliases` (wrap `ssh -F ~/.ssh-local/config`), guarded so they only appear when the jump config was generated.
+- Because this touches `Dockerfile.base` inputs (`rootfs/`, `entrypoint-user.sh`), the base image rebuilds and `base-latest` advances.
+
+### Added: pi-fork (`fork`) + pi-observational-memory (`recall`) in pi variants
+
+The `with-pi` and `omos-with-pi` variants now bake in two pi extensions from `github.com/elpapi42`:
+
+- `Dockerfile.variant` clones both repos to `/opt/pi-fork` and `/opt/pi-observational-memory` and runs `npm install` there at **build** time (a local-path `pi install` does not npm-install, so deps must be present for the extension to load).
+- `entrypoint-user.sh` registers them at runtime via `pi install /opt/<pkg>` (instant, in-place, idempotent; `fork`/`recall` tools bind on the next pi start).
+- CI (`resolve-versions`) resolves the `master` HEAD of each repo to a concrete commit SHA and passes it as `PI_FORK_REF` / `PI_OBSMEM_REF` build-args — same registry-buildcache cache-hit guard used for `PI_VERSION` / `OMOS_VERSION`.
+- New build-args: `PI_FORK_REPO`, `PI_FORK_REF`, `PI_OBSMEM_REPO`, `PI_OBSMEM_REF`.
+- Smoke test asserts the `/opt` clones + baked `node_modules` exist and that both packages register in `settings.json`. Size thresholds bumped: `with-pi` 2700→2900 MB, `omos-with-pi` 3700→3900 MB (fork's `@earendil-works` peer deps add ~150 MB).
+
+### Added: `pi-only` variant (basis for `pi-devbox`)
+
+New fifth published variant built with `INSTALL_OPENCODE=false`, `INSTALL_PI=true` — pi + companions (toolkit, extensions, `fork`, `recall`) and all base tooling, but **without** opencode (~145 MB lighter than `with-pi`).
+
+- Published as `latest-pi-only` / `vX.Y.Z-pi-only` (multi-arch). New CI jobs `smoke-pi-only` and `build-variant-pi-only`; wired into `promote-base-latest` / `update-description` needs.
+- This is the **single source of truth** for the separate [`joakimp/pi-devbox`](https://gitea.jordbo.se/joakimp/pi-devbox) image, which now `FROM`s `latest-pi-only` instead of duplicating the pi-install logic. Lets pi-devbox stay lean and pi-focused while the install logic lives in one place.

+
+## v1.15.12 — 2026-05-29
+
+First container build on the genuine `opencode-ai@1.15.12` upstream release (published 2026-05-28). Also bumps pi `0.76.0` → `0.77.0`.
+
+> **Note on the `v1.15.12` git tag:** an earlier `v1.15.12` git tag existed at commit `be2a168` as a historical artifact from the 2026-05-28 versioning slip (re-cut as `v1.15.11c` once the slip was caught). The corresponding Hub `v1.15.12*` images were manually deleted at the time. Now that opencode upstream has actually released 1.15.12, the tag is being re-used at HEAD per the `v{opencode_version}[letter]` scheme — the old tag was force-overwritten locally and on origin. Commit `be2a168` and the v1.15.11c CHANGELOG block (which references the slip) remain in history.
+
+### Bumped: opencode-ai 1.15.11 → 1.15.12
+
+Notable upstream changes (from the [anomalyco/opencode v1.15.12 release](https://github.com/anomalyco/opencode/releases/tag/v1.15.12)):
+
+- **Core** — ACP integrations can send prompts/slash-commands/usage updates through `acp-next`; experimental WebSocket transport for OpenAI Responses (`OPENCODE_EXPERIMENTAL_WEBSOCKETS=true`); adaptive reasoning enabled for Anthropic Opus 4.7+.
+- **Bugfixes** — colons allowed in passwords; faster warm `acp-next` model/config switches; OpenAI WebSocket response timeouts kept active with retries before fallback; `acp-next` permission prompts handled correctly; persisted session directory used for existing-session requests; remote workspace request bodies forwarded correctly; custom base URLs supported for OpenAI WebSocket Responses.
+- **TUI** — workspace management dialog; session navigation works while prompt modes are open; thinking spinner restored; subagent retry status surfaced; opening editors from non-Git project paths fixed.
+- **Desktop** — tab-layout setting; home empty state and V2 font usage improved; tab close buttons showing reliably.
+
+### Bumped: pi 0.76.0 → 0.77.0
+
+Notable upstream changes (from pi's CHANGELOG):
+
+- **Claude Opus 4.8 support** — model metadata + adaptive-thinking coverage updated.
+- **Selective tool disablement** — `--exclude-tools` / `-xt` disables specific built-in, extension, or custom tools while keeping the rest available.
+- **Headless Codex subscription login** — `/login` can use device-code auth for ChatGPT Plus/Pro Codex subscriptions.
+- **Streaming-aware extension input** — `InputEvent.streamingBehavior` lets extensions distinguish idle prompts, mid-stream steers, and queued follow-ups.
+- **Bugfixes** — startup timing output excludes `createAgentSessionRuntime`; OpenRouter DeepSeek V4 `xhigh` reasoning preserved; SIGTERM/SIGHUP run extension `session_shutdown` cleanly; keyboard protocol negotiation ignores delayed terminal responses; Windows MSYS2 ucrt64 startup crash fixed; API-key/header config resolution treats plain strings as literals with `$ENV_VAR` interpolation; session disposal aborts in-flight work; numerous provider-specific reasoning/metadata fixes (Codex Responses replay, OpenAI/OpenRouter GPT-5.5 Pro, Kimi K2.6, Xiaomi Token Plan).
+
+### Inheritance from base
+
+No base change — `base-latest` is reused unchanged from v1.15.11c (`base-decide` short-circuits at the Hub-probe step). SSH ControlMaster on a writable socket path, gitleaks, and git-crypt continue to ride along from the base.
+
+### Workflow status
+
+This is the first opencode-version-bump publish exercising the afternoon-of-2026-05-28 workflow changes (cache-export removal + 3-attempt retry wrapper) end-to-end on a real upstream release. v1.15.11c proved the publish path mechanically; v1.15.12 is the first one with both an opencode bump and a pi bump driving fresh variant layers.
+
+## v1.15.11c — 2026-05-28
+
+**Re-cut of v1.15.12 to fix a versioning-scheme violation.** The morning's v1.15.12 release was tagged in error: `opencode-ai` stayed at `1.15.11` upstream (no 1.15.12 exists on npm), so per the project's `v{opencode_version}[letter]` scheme this should have been the third container build on opencode 1.15.11 — `v1.15.11c` — not a new minor version bump. The `v1.15.12` git tag and the eight `v1.15.12*` / `latest*` Docker Hub images remain as historical artifacts but are superseded by this release. Future builds on opencode 1.15.11 continue the letter sequence as `v1.15.11d`, `v1.15.11e`, … — v1.15.12 will only be reused if and when opencode upstream actually releases 1.15.12.
+
+Content inherited from v1.15.12 (see that block below for the full diagnostic chain on the v4.0.0 pin disproof and the manual host-side publish):
+
+- pi `0.75.5` → `0.76.0`.
+- `setup-buildx-action` pin reverted from `@v4.0.0` back to `@v4` (the v1.15.11b regression hypothesis was disproven).
+- Inheritance from base: SSH ControlMaster on a writable socket path, gitleaks, git-crypt.
+- Cache-hit silent same-bytes regression fix carried forward from v0.75.5b's pattern.
+
+Additional changes since v1.15.12 (afternoon 2026-05-28 followup work):
+
+### Hub-push regression — root cause identified, CI fixed
+
+The `400 Bad request` from `registry-1.docker.io` that broke CI publishing across runs #332/333/334/336 (and forced v1.15.12 to ship via manual host-side push) is **buildkit's registry cache-export with `mode=max`**, not the image push itself.
+
+**Diagnostic that nailed it:** the manual v1.15.12 publish from an Orbstack host reproduced the exact same 400 — but only on the cache-export step. Image layers pushed cleanly (911s for the base, all variants succeeded). Dropping `--cache-to` from the manual script let the publish complete. Running the same buildx version against the same Hub account from the same network, the only differential was cache export vs. image export.
+
+This explains every observation:
+
+- Failure shape stable across attempts (`Offset:0`, HTML body, CDN-tier rejection): cache-export protocol-level mismatch, not transient network or per-blob corruption.
+- Repo-specific (`joakimp/opencode-devbox` only): we're the only Hub repo currently writing a `:base-buildcache` tag with `mode=max`.
+- Started ~2026-05-23: lines up with buildx 0.34.x rolling out and bundling moby/buildkit v0.30.0, which changed the `_state` token format on resumable cache uploads.
+- Image push works fine: cache-export is a separate codepath using a different manifest/layer scheme.
+- Action-pin to `setup-buildx-action@v4.0.0` didn't help: that pin pulls older actions-toolkit, but the bundled buildkit was still 0.34.x via Buildx CLI on the runner image. Pin was correctly disproven by run #336.
+
+### Workflow change
+
+- **`.gitea/workflows/docker-publish-split.yml`** — registry cache (`cache-from`/`cache-to`) removed from the `build-base` step. Comment in place documenting the regression and the re-enable condition. Variants don't use registry cache so they're untouched. The base tag is content-addressed (`base-<hash>` derived from Dockerfile.base + rootfs/* + entrypoint*.sh) so unchanged bases short-circuit at the Hub-probe step in `base-decide` and never re-build anyway — the lost cache only affects the rare case of a Dockerfile.base change, where we now pay the full ~3 min build instead of pulling cached layers. Acceptable trade-off vs. broken publishes.
+
+Next tag push (e.g. v1.15.13) is expected to publish cleanly via Gitea CI again. validate.yml on this main push will be the first real-time test of the smoke side; full publish path will be tested on the next opencode bump or by a deliberate letter-suffix re-tag.
+
+### Status of earlier suspects
+
+- ~~`setup-buildx-action@v4.1.0`~~ — disproven by v1.15.11b CI run #336 with v4.0.0 pin failing identically. Pin reverted in v1.15.12. Not the regressor.
+- ~~`@docker/actions-toolkit 0.79.0 → 0.90.0`~~ — rolled back via the action pin; same failure. Not the regressor.
+- ~~Account / repo / Hub-CDN globally~~ — local pushes from developer host succeed. Always was healthy.
+- ~~`catthehacker/ubuntu:act-latest`~~ / ~~act-runner egress~~ — manual publish from host reproduced the same 400, ruling out runner-side network. Not the cause.
+- **Confirmed:** buildkit cache-export protocol (mode=max) hitting Hub-CDN edge rejection. Workaround: don't export cache to registry. Long-term: track moby/buildkit upstream for protocol fix or switch to GHA cache (not portable to Gitea Actions).
+
+### Docs: manual host-publish runbook + script archive
+
+- `docs/manual-host-publish.sh` — the literal script that shipped v1.15.12 from a developer Mac via Orbstack, preserved as-is.
+- `docs/manual-host-publish.md` — runbook explaining when to reach for the escape hatch, the four constants to edit (`RELEASE_TAG`, `BASE_HASH`, `PI_VERSION`, `OMOS_VERSION`), three sources for `BASE_HASH` (CI's `base-decide` log = canonical, Hub `base-latest` probe, local recompute matching CI's exact recipe including `__pycache__`/`.DS_Store`/`._*` junk filters), and adaptations for pi-devbox / letter-suffix rebuilds / partial-failure single-variant recovery.
+- `AGENTS.md` — new Critical conventions bullet documenting that `cache-from`/`cache-to` is currently disabled, why, and the re-enable condition.
+
+### CI: workflow-level retry around `docker buildx build --push`
+
+All five push steps in `.gitea/workflows/docker-publish-split.yml` (1 base + 4 variants) are now wrapped in a 3-attempt retry loop with backoff (15s, 30s) as belt-and-braces against transient `registry-1.docker.io` blips. Replaces the `docker/build-push-action@v7` invocations with `shell: bash` steps that run `docker buildx build --push` directly so the loop is visible and tweakable. Smoke-test build steps (`load: true`, no push) are unchanged — they don't suffer from registry-side flakiness.
+
+Does **not** mask deterministic failures: a true regression (e.g. the cache-export 400 documented above) will fail all 3 attempts identically and the job still fails by design. Belt-and-braces with the workflow-level retry-on-failure rerun heuristic in the `ci-release-watcher` skill, which catches transient-shaped runner-side failures separately. No image-side change.
+
+### AGENTS.md addition: pre-flight scheme check
+
+New "Versioning scheme" subsection documenting the **mandatory `npm view opencode-ai version` pre-flight check** before cutting any non-letter-suffixed tag, with this slip cited as the cautionary example.

-## v1.15.11 — 2026-05-27
+## v1.15.12 — 2026-05-28
+
+> **Note (2026-05-28 PM):** this tag violates the project's `v{opencode_version}[letter]` versioning scheme — there is no `opencode-ai@1.15.12` on npm; OPENCODE_VERSION stayed at 1.15.11 across this build. Re-cut as `v1.15.11c` at HEAD per the scheme. The git tag and Hub images for `v1.15.12*` remain as historical artifacts but are superseded by `v1.15.11c`. See the `v1.15.11c` block above for the corrected release notes.
+
+Manual-published release. Reverts the `setup-buildx-action@v4.0.0` pin from v1.15.11b (hypothesis was disproven — see below) and bumps the bundled `pi-coding-agent` to 0.76.0 via the floating `PI_VERSION=latest` resolution.
+
+### Why "manual-published"
+
+v1.15.11b reproduced the exact same Hub `400 Bad request` regression as v1.15.11 (CI run #336, build-base failed twice including a Gitea auto-rerun), confirming `setup-buildx-action@v4.1.0` is **not** the regressor. After four consecutive identical CI failures across two days, the SSH-CM and gitleaks fixes were shipped by hand from a developer host's Orbstack/Docker-Desktop — a path we already knew worked in ~25s for the same multi-arch build to the same Hub account.
+
+This release ships the same content the runner-side build would have shipped; it just bypasses the broken runner-network → Hub-CDN combo. CI auto-publishing remains broken pending separate runner-side investigation (see [AGENTS.md — known issues](AGENTS.md)).
+
+### Workflow change
+
+- **`.gitea/workflows/docker-publish-split.yml`** — all nine `setup-buildx-action@v4.0.0` pins reverted to `@v4`. The pin added no value (failure reproduced) and was holding us off action improvements.
+
+### Bumped: pi-coding-agent (latest → 0.76.0)
+
+`PI_VERSION=latest` in `Dockerfile.variant` resolves at build time. 0.76.0 was published 2026-05-27 20:03 UTC. No Dockerfile edit needed; floating-`latest` is intentional so each opencode-devbox release pulls the freshest pi without a manual bump.
+
+### Hub-push regression — ruled out / still suspect
+
+**Ruled out:**
+- `setup-buildx-action@v4.1.0` — v4.0.0 reproduces the failure identically.
+- `@docker/actions-toolkit 0.79.0 → 0.90.0` — rolled back via the action pin; same failure.
+- Account / repo / Hub-CDN globally — local pushes from a developer host succeed.
+- Multi-arch as such — pi-devbox v0.75.5b pushed multi-arch on 2026-05-23.
+
+**Still suspect:**
+- `catthehacker/ubuntu:act-latest` runner image (floating, not pinned in workflows).
+- act-runner host network egress from `runner-2` (sustained CDN-edge rejection from this specific source IP).
+- buildx 0.34.x's signed `_state` token format hitting a Hub-edge WAF/length rule that didn't apply to 0.33.x.
+- Hub-side per-repo state for `joakimp/opencode-devbox` specifically (other Hub repos from the same account work).
+
+Four failing runs share the exact failure shape: HTTP 400 with HTML body (CDN-tier, not registry backend) on the very first PUT (`Offset:0`) of the resumable layer-blob upload. UUIDs and `_state` signatures differ across attempts — only the failure pattern is stable.

+
+## v1.15.11b — 2026-05-27
+
+Container-level rebuild of v1.15.11. The original v1.15.11 release-day publish failed three times in a row (CI runs #332/333/334) with identical `400 Bad request` responses from `registry-1.docker.io` on the buildx layer-blob PUT. Build itself succeeded 30/30 each time; only the multi-arch push failed. Triaged on 2026-05-27 evening:
+
+- **Local multi-arch buildx push from a developer host succeeds in ~25s** — same Hub account, same multi-arch path. Account, repo, and Hub-CDN are all healthy.
+- **Last known-good Gitea Actions Hub push: 2026-05-23 ~20:26 UTC** (`pi-devbox v0.75.5b`). All Gitea-runner-driven pushes since 2026-05-24 have failed identically.
+- **Smoking gun candidate:** `docker/setup-buildx-action@v4` floats to `v4.1.0` (published 2026-05-22 16:00 UTC). Action-resolver caches on the runner appear to have rolled forward to v4.1.0 sometime between the May 23 success and the first May 24 failure. v4.1.0 ships a newer bundled buildx/buildkit which may be using a different push protocol that trips Hub's CDN URI-length cap (the failing `_state` query string is ~1.4 KB).
+
+### Workflow change
+
+- **`.gitea/workflows/docker-publish-split.yml`** — all nine `docker/setup-buildx-action@v4` uses pinned to `@v4.0.0`. `setup-qemu-action@v3` left floating since QEMU wasn't in the suspected blast radius and was working on May 23. If v4.0.0 publishes cleanly we keep the pin and file an upstream buildkit/buildx issue documenting the regression.
+
+No other source changes — same `OPENCODE_VERSION=1.15.11`, same `Dockerfile.base` and `Dockerfile.variant`, same SSH-CM bake, same gitleaks. v1.15.11 (the original tag) is preserved in the repo as a historical marker of the first publish attempt; v1.15.11b is the canonical release.
+
+### v1.15.11
 
 First release on opencode 1.15.11. Also bakes in four devbox-side fixes accumulated since v1.15.10 (SSH ControlMaster on a writable path, gitleaks added to base, CI resolve-versions hardening, CI cache-hit regression fix). Downstream pi-devbox inherits all of these on its next build against `base-latest`.

+### Reaching your LAN from the container
+
+The devbox works the same way whether the host is **native Linux Docker** or a **VM-backed** runtime (macOS OrbStack / Docker Desktop, or Docker Desktop on Windows) — but their networking differs:
+
+- **Native Linux Docker:** the host NATs container egress onto its LAN, so other devices on your LAN are reachable directly. Nothing to configure.
+- **VM-backed (macOS / Docker Desktop):** the container runs in a Linux VM behind the host's network stack. The host's *directly-attached* LAN peers are **not** bridged into the container by default — only the host itself and *routed* subnets are reachable.
+
+On every start the entrypoint detects which case applies. On VM-backed hosts it generates a writable `~/.ssh-local/config` that uses the **host as an SSH jump** to reach LAN peers; on native Linux it does nothing.
+
+**To enable it on a VM-backed host:**
+
+1. Set `HOST_SSH_USER=<your host username>` in `.env`.
+2. Start the container once. The entrypoint prints a public key — append it to your host's `~/.ssh/authorized_keys`.
+3. Ensure the host's SSH server is on (on macOS: System Settings → General → Sharing → Remote Login).
+4. Reach the host with `dssh host`, and reach LAN peers by adding `ProxyJump host` to their entries in your bind-mounted `~/.ssh/config`:
+
+```sshconfig
+# in your host ~/.ssh/config (mounted read-only into the container)
+Host my-nas
+    HostName 192.168.1.50
+    User admin
+    ProxyJump host
+```
+
+Then `dssh my-nas` routes container → host → LAN peer. (`dssh`/`dscp` wrap `ssh -F ~/.ssh-local/config`; the host config is pulled in via `Include`.)
+
+> This ships the **mechanism** only — your specific target hosts live in your own `~/.ssh/config`, never baked into the image. Set `DEVBOX_LAN_ACCESS=off` to disable, or `=jump` to force it (e.g. native Linux with `extra_hosts: ["host.docker.internal:host-gateway"]`).
+
 ### Custom opencode config
 
 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.

+# Manual host-side publish — escape hatch when CI is broken
+
+This runbook is the procedure for publishing an opencode-devbox release **directly from a developer host** when the Gitea Actions → Docker Hub path is broken. Used in anger on 2026-05-28 to ship `v1.15.12` after five consecutive CI publish failures (runs #332/333/334/336 + a rerun) and as a parallel diagnostic that pinpointed the root cause (buildkit `cache-export mode=max` returning HTTP 400 from the Hub CDN).
+
+The procedure is also a **diagnostic probe**. If the host-side publish succeeds where CI fails, the failure is somewhere in the runner → Hub path (cache-export, runner egress, runner-image, action versions). If host-side fails the same way, the failure is in your local buildx + Hub combination and you need a different escape (different network, different account, file an upstream).
+
+## When to reach for this
+
+- Tag pushed, CI keeps failing on `docker buildx build --push`, the failure shape is stable across reruns.
+- Failure body looks like a registry-tier rejection (HTTP 4xx, HTML response body, repeats on every retry) — i.e. not a transient.
+- You've already disproved the obvious suspects (action pin, runner image, network) per the [`ci-release-watcher` skill](../../../.agents/skills/ci-release-watcher/SKILL.md) playbook.
+- You need the release **shipped today** and don't want to wait for a CI fix to land + re-trigger.
+
+If CI is broken because **a workflow change you just made is bad**, fix the workflow and re-tag with a letter suffix. This runbook is for when the workflow looks correct but the publish path itself is broken.
+
+## Prerequisites on the host
+
+- Docker (or Orbstack on macOS) with `docker buildx` available — multi-arch publish needs `setup-qemu` equivalent. Orbstack ships QEMU emulators for both archs by default; on Linux install `qemu-user-static` and run `docker run --privileged --rm tonistiigi/binfmt --install all` once per host.
+- `docker login` credentials for `joakimp` on Docker Hub (PAT or password). Confirm with `docker info | grep Username`.
+- A clone of `opencode-devbox` checked out at the **exact tag** you want to publish. `git status` clean. `git describe --tags --exact-match HEAD` should print the tag.
+- Network connectivity to `registry-1.docker.io` from the host. Verify with `curl -sI https://registry-1.docker.io/v2/ | head -1` (expects `401 Unauthorized` — that's the v2 API saying "auth required", which means you can reach it).
+
+## How to use this runbook
+
+A working reference script lives next to this doc: **[`docs/manual-host-publish.sh`](manual-host-publish.sh)**. It is the literal script that shipped opencode-devbox v1.15.12 on 2026-05-28 from a developer Mac via Orbstack, with the BASE_HASH and version pins of that release. To publish a different release, **copy it to a new file, edit four constants at the top, and run it**:
+
+```bash
+cp docs/manual-host-publish.sh /tmp/manual-publish-vX.Y.Z.sh
+# Edit at top of file:
+#   RELEASE_TAG="vX.Y.Z"
+#   BASE_HASH="<12-char hash from CI's base-decide step>"
+#   PI_VERSION="<from npm registry, see step 2 below>"
+#   OMOS_VERSION="<from npm registry, see step 2 below>"
+bash /tmp/manual-publish-vX.Y.Z.sh
+```
+
+Keep the historical script in `docs/` as-is — it's an archive of the v1.15.12 publish, useful as a reference if a future debug needs to compare exact arg sets across releases. Don't edit it in place.
+
+The sections below explain what the script does and what you need to know to edit those four constants safely.
+
+## 1. Pin RELEASE_TAG
+
+The git tag you're publishing. Must match a tag in the local clone:
+
+```bash
+git fetch && git checkout v1.15.13   # whatever you're publishing
+git describe --tags --exact-match HEAD
+```
+
+The script asserts `HEAD == ${RELEASE_TAG}^{commit}` before doing anything destructive. If you've drifted, fix it with `git checkout` before running.
+
+## 2. Pin PI_VERSION and OMOS_VERSION
+
+Gitea CI's `resolve-versions` job queries the npm registry at workflow time and threads concrete versions through every variant build, mitigating the silent same-bytes-across-releases regression class documented in `AGENTS.md`. Do the same by hand:
+
+```bash
+curl -sf https://registry.npmjs.org/@earendil-works%2Fpi-coding-agent/latest | jq -r .version
+curl -sf https://registry.npmjs.org/oh-my-opencode-slim/latest | jq -r .version
+```
+
+Paste the two version strings into the script's `PI_VERSION` / `OMOS_VERSION` constants. Don't leave the script defaulting to `latest` — the registry buildcache will silently reuse a stale layer if the build-arg byte-equals a previous build.
+
+## 3. Pin BASE_HASH
+
+This is the 12-char hash that CI's `base-decide` job computes from `Dockerfile.base` + `rootfs/**` + `entrypoint*.sh`. Three ways to get it, in order of preference:
+
+**A. From a prior CI run on the same commit** (cheapest — if the Gitea Actions run that triggered on this tag got far enough to log `base-decide`'s output, just read it):
+
+```
+Gitea Actions → the run for vX.Y.Z → base-decide job → "Compute base tag" step → last line:
+   Computed base tag: base-XXXXXXXXXXXX
+```
+
+This is the canonical source. The whole reason for the manual escape is that *something later in CI broke* — `base-decide` itself is fast, deterministic, and almost always succeeds.
+
+**B. From an existing image on the Hub** if a recent release already published a `base-<hash>` tag and the inputs haven't changed, you can copy that hash. Confirm with `docker manifest inspect joakimp/opencode-devbox:base-latest` and read the digest — if it matches a `base-<hash>` you already see on the Hub, that hash is yours.
+
+**C. Compute it locally**, replicating CI's exact recipe (the script in `.gitea/workflows/docker-publish-split.yml` `base-decide.compute`):
+
+```bash
+{
+  cat Dockerfile.base
+  find rootfs -type f \
+    ! -path '*/__pycache__/*' \
+    ! -name '*.pyc' \
+    ! -name '.DS_Store' \
+    ! -name '._*' \
+    -print0 2>/dev/null | sort -z | xargs -0 cat 2>/dev/null
+  cat entrypoint.sh entrypoint-user.sh
+} | sha256sum | cut -c1-12
+```
+
+The junk-file filters (`__pycache__`, `.DS_Store`, `._*` AppleDouble) matter — they are gitignored but `find -type f` picks them up locally and would diverge your hash from CI's clean checkout. Don't skip them.
+
+If method C disagrees with method A, **trust A** and find out why your local tree differs. The hash in CI is what's on the Hub; that's what variants must FROM.
+
+## What the script does (high level)
+
+After the constants are set, the script runs a 5-step procedure. No editing needed inside the body; the whole flow is parameterised by the four constants above plus `IMAGE` (which is fixed to `joakimp/opencode-devbox`).
+
+1. **Preflight** — buildx present, tag exists, `HEAD == tag`, multi-arch builder created if missing.
+2. **Base build (conditional)** — probe `${IMAGE}:base-${BASE_HASH}` on the Hub; if missing, build it multi-arch and push. **No `--cache-from` / `--cache-to`.** That's the whole point of this escape. If the base push itself fails the same way CI did, stop — the regression has spread to image push and you need a different host or account, not this runbook.
+3. **Promote `base-latest`** — `docker buildx imagetools create` re-tags by manifest reference. No rebuild.
+4. **Variants × 5** — sequential (not parallel; one host's egress can't saturate five multi-arch pushes safely). Each variant is `Dockerfile.variant` `FROM ${IMAGE}:base-${BASE_HASH}` plus the appropriate `INSTALL_OPENCODE` / `INSTALL_OMOS` / `INSTALL_PI` build-args, tagged `${RELEASE_TAG}${suffix}` and `latest${suffix}`.
+5. **Verify** — prints the digest of all 12 expected tags (10 variant + base-hash + base-latest). Spot-check that each `vX.Y.Z*` and its `latest*` alias share a digest.
+
+Expected wall time on a recent Mac: ~25-40 min (base ~3 min if rebuilt, each variant ~3-7 min mostly QEMU arm64 emulation).
+
+## Optional: update DOCKER_HUB.md description
+
+CI's `update-description` job posts the rendered Hub description via the Hub API. The manual script does **not** do this — the release works fine without it. If you want parity, copy the curl invocation from the `update-description` job in `.gitea/workflows/docker-publish-split.yml` and run it from the host with a Hub PAT loaded into `HUB_PAT`. Cosmetic; can wait until CI is healthy and the next release pushes a fresh description automatically.
+
+## After: capture diagnostic value
+
+The whole point of running this manually is the diagnostic. Three things to record before moving on:
+
+1. **Did the host publish succeed?** If yes and CI was failing on the same exact code, you've localised the failure to the runner side (cache-export, network, runner image). If no, the failure is in your local buildx + Hub combination and CI is a victim, not a cause.
+2. **What was different from CI?** Document at minimum: `docker buildx version`, the host's `buildx ls` output (driver name + version), whether you used `--cache-to` or not, and which network you were on.
+3. **File the upstream.** If the diagnostic narrowed the failure to a specific buildkit/buildx behaviour, file at `moby/buildkit` or `docker/buildx` with: stable failure shape, the exact request URL fragment (`Offset:0` / `_state=...` / digest if visible), the timeline boundary when failures started, and what worked vs what failed in your repro. The 2026-05-28 cache-export-mode=max regression is a worked example.
+
+Restore CI as the primary publish path as soon as the underlying regression is fixed or worked around at workflow level. This runbook should be exercised rarely.
+
+## Variants of this runbook
+
+- **pi-devbox** — same idea, simpler: only one image (`joakimp/pi-devbox`), one tag pair (`vX.Y.Z` + `latest`), no split base. Adapt the script: drop the `BASE_HASH` constant + steps 2-3 + the variant function; replace with a single `docker buildx build --file Dockerfile --build-arg PI_VERSION=... --tag joakimp/pi-devbox:${RELEASE_TAG} --tag joakimp/pi-devbox:latest --push .`.
+- **opencode-devbox letter-suffix rebuild** (e.g. `v1.15.12b`) — same procedure end-to-end. The `BASE_HASH` will probably be unchanged from the prior release if no rootfs/entrypoint/Dockerfile.base changes shipped, so the base-build step skips itself automatically via the Hub probe.
+- **Single-variant publish** for partial-failure recovery (e.g. CI succeeded for base + 3 variants but the 4th failed) — comment out the three completed `build_variant` calls in your copy of the script. Keep `imagetools create` for `base-latest` only if it didn't already promote. Then re-run.

+# Plan: LAN-access mechanism + pi-fork/pi-observational-memory in the builds
+
+Status: PROPOSED (2026-06-03, decisions folded in). Author: pi (devbox session).
+Scope: opencode-devbox base + variant, pi-devbox. Two independent work items.
+
+---
+
+## Layering decision
+
+| Capability | Lives in | Why |
+|---|---|---|
+| **LAN-access (smart-detect host-jump)** | opencode-devbox **base** | Both opencode-devbox and pi-devbox inherit it; not pi-specific. |
+| **pi-fork + pi-observational-memory** | **pi layer** (variant `with-pi`/`omos-with-pi` + pi-devbox/Dockerfile) | Only meaningful when `pi` is present. Runtime deploy via the shared base `entrypoint-user.sh`, guarded by `command -v pi`. |
+
+Guiding principle for LAN access: **ship the mechanism, not the policy.**
+The image provides a generic `host` jump alias + writable SSH config + detection.
+A user's *specific* targets (e.g. pve/pve-2) come from their bind-mounted
+`~/.ssh/config` (`ProxyJump host`) or an env list — never hardcoded in the image.
+
+---
+
+## ITEM A — LAN access (opencode-devbox base)
+
+### Why it can't "just work" unattended
+- macOS (OrbStack / Docker Desktop): container is in a Linux VM behind the host's
+  stack. Directly-attached LAN peers are not bridged by default; only the host +
+  routed subnets are reachable.
+- Linux Docker: default bridge already NATs container egress onto the host's LAN,
+  so LAN peers are usually directly reachable. The jump is unnecessary.
+- The jump path needs the host running sshd + the container's pubkey authorized.
+  The average DockerHub t"kick the tires" user has neither → setup must be
+  **opt-in / non-fatal**, never block startup.
+
+### New file: `rootfs/usr/local/lib/opencode-devbox/setup-lan-access.sh`
+COPY'd automatically (base already does `COPY rootfs/usr/local/lib/opencode-devbox/`).
+
+Behavior, driven by `DEVBOX_LAN_ACCESS=auto|jump|off` (default `auto`):
+
+1. `off` → return immediately.
+2. Detect environment:
+   - VM-backed Docker (OrbStack / Docker Desktop) iff `getent hosts host.docker.internal`
+     resolves (OrbStack also exposes `host.orb.internal`). Native Linux → no resolution
+     (unless the user added `extra_hosts: host.docker.internal:host-gateway`).
+3. `auto` + native Linux → do nothing (direct LAN works); print one info line.
+4. `auto` + VM-backed, or `jump` forced →
+   - Create writable `~/.ssh-local/{,cm/}`, `chmod 700`.
+   - Generate `~/.ssh-local/devbox_jump_ed25519` if absent (preserve across restarts).
+   - Render `~/.ssh-local/config`:
+     ```
+     Host *
+         UserKnownHostsFile ~/.ssh-local/known_hosts
+         StrictHostKeyChecking accept-new
+     Host host mac                       # 'mac' kept as friendly alias
+         HostName host.docker.internal
+         User ${HOST_SSH_USER}           # REQUIRED for auth; see below
+         IdentityFile ~/.ssh-local/devbox_jump_ed25519
+         IdentitiesOnly yes
+         ControlMaster auto
+         ControlPath ~/.ssh-local/cm/%r@%h:%p
+         ControlPersist 4h
+     # Optional per-target blocks generated from DEVBOX_LAN_HOSTS (see below)
+     Include ~/.ssh/config               # user's bind-mounted targets still resolve
+     ```
+   - If `HOST_SSH_USER` unset → still render config but print a clear hint block:
+     the generated **public key** + the one-liner to authorize it on the host
+     (`echo '<pubkey>' >> ~/.ssh/authorized_keys`) + "enable Remote Login".
+   - Idempotent: re-render config each start (cheap); never regenerate the key.
+   - DECISION #5: NO `DEVBOX_LAN_HOSTS` env. Keep the image policy-free. Users add
+     `ProxyJump host` to their own target entries in the bind-mounted `~/.ssh/config`
+     (pulled in by the `Include ~/.ssh/config` line).
+
+### `entrypoint-user.sh`
+Call `setup-lan-access.sh` right after the existing `/tmp/sshcm` block
+(non-fatal: `… || true`). It's environment-gated so it self-skips on Linux.
+
+### `rootfs/home/developer/.bash_aliases`  (per your note — alias goes HERE)
+Append, guarded:
+```bash
+# dssh — ssh using the container's writable LAN-access config (host-jump).
+# Only useful when setup-lan-access.sh generated ~/.ssh-local/config.
+if [ -r "$HOME/.ssh-local/config" ]; then
+  alias dssh='ssh -F "$HOME/.ssh-local/config"'
+  alias dscp='scp -F "$HOME/.ssh-local/config"'
+fi
+```
+Migration caveat: skel `.bash_aliases` is only copied when absent, so existing
+volumes/containers won't get `dssh` until they `rm ~/.bash_aliases` and recreate,
+OR drop the alias into the host-shared `~/.config/devbox-shell/bash_aliases`
+(already sourced at the top of the skel file).
+
+### Dockerfile.base
+No structural change required (script ships via existing rootfs COPY). Optionally
+document `DEVBOX_LAN_ACCESS` / `HOST_SSH_USER` / `DEVBOX_LAN_HOSTS` in `.env.example`
+and README.
+
+---
+
+## ITEM B — pi-fork + pi-observational-memory (pi layer)
+
+Sources (pinned this week):
+- `github.com/elpapi42/pi-fork`                  (registers `fork`; ~v0.1.0)
+- `github.com/elpapi42/pi-observational-memory`  (registers `recall`; default branch **master**, v3.0.2)
+
+### B1 RESOLVED (verified live 2026-06-03 in this container)
+- `pi install <local-path>` is INSTANT (~0.5s): NO copy, NO npm install. pi registers
+  the path and loads the extension IN PLACE from that dir.
+- settings.json stores a RELATIVE path (e.g. `../../../opt/pi-fork` from ~/.pi/agent).
+  Points into the image-layer `/opt` → stable across volume recreate. Good.
+- Idempotent: a second `pi install <same path>` does NOT duplicate the entry.
+- CONSEQUENCE: because pi does NOT npm-install a local path, deps must already exist
+  at `/opt/<pkg>/node_modules`. pi-fork imports `@sinclair/typebox` + `@earendil-works/*`
+  peers; git-install produced a 148 MB node_modules. So we MUST `npm install` inside
+  each `/opt/<pkg>` AT BUILD TIME.
+- BAKE RECIPE: clone to /opt -> `npm install` there (build) -> `pi install /opt/<pkg>`
+  at runtime (instant, idempotent).
+- (Optional size win, verify-first: prune to external-only deps if pi provides the
+  `@earendil-works/*` peers from its own runtime resolution. ~148M is mostly those.)
+
+### DECISION #3: refactor to remove duplication
+`pi-devbox/Dockerfile` currently duplicates the pi-install + /opt-clone logic from
+`Dockerfile.variant`. Refactor `pi-devbox/Dockerfile` to `FROM` the `with-pi` variant
+image so pi-install logic (incl. the new fork/obsmem clones) lives in ONE place.
+
+> **Implementation update (2026-06-03):** `FROM with-pi` would have dragged opencode
+> into pi-devbox (all opencode-devbox variants set `INSTALL_OPENCODE=true`), making it
+> nearly identical to `latest-with-pi`. So a 5th variant **`pi-only`**
+> (`INSTALL_OPENCODE=false`, `INSTALL_PI=true`) was added to opencode-devbox, and
+> pi-devbox now `FROM`s `latest-pi-only`. Same single-source-of-truth win, but
+> pi-devbox stays lean (no opencode, ~145 MB lighter than with-pi).
+
+### Build time — clone to /opt + npm install (mirror pi-toolkit/extensions pattern)
+Add to the single `INSTALL_PI=true` block in `opencode-devbox/Dockerfile.variant`
+(after refactor, pi-devbox inherits it):
+```dockerfile
+ARG PI_FORK_REPO=https://github.com/elpapi42/pi-fork.git
+ARG PI_FORK_REF=<pin: tag or commit SHA>
+ARG PI_OBSMEM_REPO=https://github.com/elpapi42/pi-observational-memory.git
+ARG PI_OBSMEM_REF=master   # pin to SHA in CI to dodge cache-hit footgun
+# ... inside the INSTALL_PI / pi-install RUN, after the pi-toolkit/extensions clones:
+git_clone_retry "$PI_FORK_REPO"   "$PI_FORK_REF"   /opt/pi-fork && \
+git_clone_retry "$PI_OBSMEM_REPO" "$PI_OBSMEM_REF" /opt/pi-observational-memory && \
+(cd /opt/pi-fork && npm install --no-audit --no-fund) && \
+(cd /opt/pi-observational-memory && npm install --no-audit --no-fund) && \
+echo "pi-fork at $(cd /opt/pi-fork && git rev-parse --short HEAD)" && \
+echo "pi-obsmem at $(cd /opt/pi-observational-memory && git rev-parse --short HEAD)"
+```
+NOTE: `git_clone_retry` uses `--branch "$ref"`, which accepts tags & branches but
+NOT arbitrary commit SHAs. For SHA pinning use `git clone <url> <dest> && git -C
+<dest> checkout <sha>` for these two repos.
+
+### Why not bake the install result
+`~/.pi` is a named volume mounted at runtime — anything `pi install`'d into
+`~/.pi/agent/...` at BUILD time is hidden by the volume. Same reason
+pi-toolkit/extensions deploy at runtime via `entrypoint-user.sh`. So:
+
+### Runtime deploy — `entrypoint-user.sh` (shared base, in the `command -v pi` block)
+After the pi-extensions `install.sh` call, add an idempotent install of each /opt pkg:
+```bash
+for pkg in /opt/pi-fork /opt/pi-observational-memory; do
+  [ -d "$pkg" ] || continue
+  name=$(basename "$pkg")
+  # skip if already registered in settings.json packages
+  if ! grep -q "$name" "$HOME/.pi/agent/settings.json" 2>/dev/null; then
+    (cd "$HOME" && pi install "$pkg") || echo "WARN: pi install $name failed (continuing)"
+  fi
+done
+```
+`fork` + `recall` tools register on the NEXT pi start after deploy (exts bind at
+startup). First deploy after a volume recreate pays an `npm install` cost
+(pi-fork pulls ~133 deps) — acceptable, one-time per volume lifetime.
+
+OPEN ITEM B1 (verify before finalizing): exact `pi install <local-path>` semantics
+— does it copy/symlink, and does it npm-install at run each time? If it re-resolves
+deps every start, pre-populate `/opt/<pkg>/node_modules` at build (`npm install
+--omit=dev`) and confirm the runtime install reuses it. Quick test in this container:
+`pi install /opt/pi-fork` twice, observe settings.json + timing + tool registration.
+
+### CI — `.gitea/workflows/docker-publish-split.yml` (DECISION #2: latest-but-pinned)
+- USE LATEST CONTENT, BUT RESOLVE TO A SHA IN CI (same pattern as PI_VERSION/OMOS).
+  The existing `resolve-versions` job curls npm `latest` for pi/omos to defeat the
+  build-arg cache-hit footgun. Add an analogous resolve for the two git repos:
+  query the GitHub API for the HEAD commit SHA of the tracked branch (master) and
+  pass it as `PI_FORK_REF` / `PI_OBSMEM_REF` build-args, so the layer hash changes
+  when upstream moves AND we still get newest-at-build-time.
+- Passing a bare branch name would be byte-identical across builds -> stale cached
+  layer (the documented footgun). SHA resolution fixes both.
+- Pass the new build-args in the `with-pi` and `omos-with-pi` build steps.
+- The resolved SHAs print in build logs (and ideally as image labels) so a bad
+  upstream is diagnosable and we can pin back to a known-good SHA.
+
+### Version coupling risk (carry-over from prior session)
+pi-fork/obsmem extensions are coupled to the host pi version (AGENTS.md warns).
+pi-fork had a `fix/effort-string-enum-schema` branch from recent API churn. So:
+- Pin against the SAME `PI_VERSION` the image ships.
+- smoke-test must assert the tools actually register (below), not just that files exist.
+
+### Smoke test — `scripts/smoke-test.sh`
+Add (for `with-pi`/`omos-with-pi`/pi-devbox):
+1. `/opt/pi-fork/package.json` and `/opt/pi-observational-memory/package.json` exist.
+2. Run a container, then assert `~/.pi/agent/settings.json` "packages" includes both.
+3. Best-effort: headless `pi` tool-list contains `fork` and `recall` (if pi exposes a
+   non-interactive list; otherwise step 2 is the gate).
+
+---
+
+## Decisions — RESOLVED 2026-06-03
+1. **B1**: VERIFIED. Local-path install is instant/in-place; bake `npm install` into
+   `/opt/<pkg>` at build; runtime `pi install /opt/<pkg>` is instant + idempotent. ✓
+2. **Latest-but-pinned**: track latest (master HEAD), resolve to SHA in CI build-arg. ✓
+3. **Refactor**: pi-devbox/Dockerfile -> `FROM` the with-pi variant; pi-install in ONE place. ✓
+4. **LAN default** `DEVBOX_LAN_ACCESS=auto`: generate config + print authorize hint when
+   `HOST_SSH_USER` unset; silent no-op on native Linux. ✓
+5. **No `DEVBOX_LAN_HOSTS`**: rely on user's bind-mounted `~/.ssh/config` (`ProxyJump host`). ✓
+
+## Remaining verify-before-merge items
+- Confirm the fork/recall extensions LOAD at runtime from `/opt/<pkg>` WITH the baked
+  node_modules (smoke test asserts tool registration, not just files).
+- Optional: confirm whether pi supplies `@earendil-works/*` peers at runtime so /opt
+  node_modules can be pruned to external-only deps (size optimization, ~148M -> small).
+
+## Rollout order
+1. Verify B1 in this live container (cheap, no build).
+2. Land ITEM A in base (rootfs script + entrypoint call + alias) → rebuild base → smoke.
+3. Land ITEM B in variant + pi-devbox + CI resolve + smoke assertions.
+4. CHANGELOG + tag both repos; CI rebuild; verify fork+recall+dssh survive a volume recreate.

+#!/usr/bin/env bash
+# setup-lan-access.sh — generic, host-OS-agnostic LAN reachability helper.
+#
+# THE PROBLEM
+#   On macOS (OrbStack / Docker Desktop) and Docker Desktop on Windows, the
+#   container runs inside a Linux VM behind the host's network stack. The
+#   host's *directly-attached* LAN peers (e.g. other boxes on 192.168.1.0/24)
+#   are NOT bridged into the container by default — only the host itself and
+#   *routed* subnets are reachable. On native Linux Docker the default bridge
+#   already NATs container egress onto the host's LAN, so LAN peers are usually
+#   reachable directly and no workaround is needed.
+#
+# THE APPROACH ("detect, and on a VM-backed host use the host as a jump")
+#   The one thing reachable from a container on every OS is the host itself
+#   (host.docker.internal). So on VM-backed hosts we generate a writable SSH
+#   config that reaches the host and lets the user ProxyJump onward to LAN
+#   peers the host can reach. On native Linux we do nothing.
+#
+#   We ship the MECHANISM (a generic `host` jump alias + writable config),
+#   never the POLICY: the user's specific target hosts live in their own
+#   bind-mounted ~/.ssh/config (add `ProxyJump host` to those entries) — which
+#   is pulled in via the `Include ~/.ssh/config` line below.
+#
+# WHY A WRITABLE SIDECAR (~/.ssh-local)
+#   The devbox typically bind-mounts the host's ~/.ssh READ-ONLY (so agents
+#   can read keys for git but can't tamper with config/known_hosts/authorized_
+#   keys). That means we cannot edit ~/.ssh/config or write ~/.ssh/known_hosts.
+#   So everything generated here lives under the writable ~/.ssh-local, used
+#   via `ssh -F ~/.ssh-local/config` (the `dssh`/`dscp` aliases wrap that).
+#
+# CONTROLS (env)
+#   DEVBOX_LAN_ACCESS = auto (default) | jump | off
+#       auto  → set up the jump config only on VM-backed hosts; no-op on Linux.
+#       jump  → always set up (e.g. native Linux with extra_hosts host-gateway).
+#       off   → do nothing.
+#   HOST_SSH_USER  — the username to SSH into the host as. REQUIRED for the
+#       jump to authenticate. If unset we still generate the config but print
+#       a hint with the public key to authorize on the host.
+#   DEVBOX_HOST_ALIAS — host hostname to reach (default host.docker.internal).
