# exomem — multi-stage container image.
#
# Four final targets share this one file:
#   lean (target `lean`, DEFAULT — base deps only, no torch, no model download)
#   ml   (target `ml`   — the `embeddings` extra, CPU-only torch, no CUDA runtime)
#   cuda (target `cuda` — the `embeddings` extra, CUDA-capable torch, CPU-default at idle)
#   cloud (target `cloud` — Exomem Cloud cell runtime, derived from `cell-runtime`)
#
# `lean` is intentionally the LAST stage in this file: `docker build .` / `docker
# buildx build .` with no `--target` builds the final stage in the file, and lean
# is meant to be that zero-argument default (matches the stdio one-liner's
# zero-Python, zero-model-download onboarding promise — see docs/docker.md).
# Build `ml` explicitly with `--target ml` (or pull the published `:ml` tag).
# Build `cuda` explicitly with `--target cuda` (or pull the published `:cuda` tag).
#
# Every stage builds from the checked-out source tree (COPY src/ pyproject.toml
# uv.lock), never a published PyPI wheel — see design.md D1.

ARG UV_VERSION=0.11.28

# COPY --from does not support ARG expansion; a global-scope FROM alias does
# (buildx's documented workaround), so the pin lives in one place above.

# builder-ml — adds the `embeddings` extra (hybrid search) with CPU-only
# torch. See design.md D2 for the full rationale; summary:
#
# pyproject.toml pins `[tool.uv.sources] torch = [{ index = "pytorch-cu132",
# marker = "sys_platform == 'win32' or sys_platform == 'linux'" }]`. This
# container's platform IS Linux, so a plain `uv sync --extra embeddings` here
# would resolve torch against the cu132 (CUDA 13.2) index — multi-GB CUDA
# wheels baked into an image with no CUDA runtime and no GPU. Instead:
#
#   1) `uv pip install torch --index-url .../cpu` — the CPU-only wheel from
#      an explicit index, bypassing [tool.uv.sources] entirely.
#   2) `uv pip install ".[embeddings]"` — the rest of the extra. `uv pip`
#      (unlike `uv sync`/`uv add`) does NOT consult [tool.uv.sources] or
#      [tool.uv.index], so it does not re-resolve/reinstall torch against the
#      CUDA index; the already-installed CPU wheel satisfies the `torch>=2.12`
#      requirement.
#
# If a future pyproject.toml edit changes the `embeddings` extra's torch pin
# in a way the pinned CPU wheel below can no longer satisfy, step 2 fails
# loudly (version conflict) — see design.md's Risks section before changing
# either the extra or this Dockerfile.

# builder-hosted — builder-lean plus ONNX Runtime and the embedding weights

#
# A hosted cell runs under a default-deny NetworkPolicy with no egress rules
# and a read-only root filesystem. It therefore cannot download a model, and
# has nowhere writable to cache one if it could. Any weight the cell needs
# must already be a layer, or the `embeddings` grant produces a cell that
# advertises semantic recall and fails on first use.
#
# This stage builds from `builder-lean`, NOT `builder-ml`: the hosted lane
# serves the same bi-encoder through ONNX Runtime, which imports ~40 MiB
# against torch's ~400 and holds a materially smaller peak. Peak per cell is
# what decides how many tenants a node carries, so torch's absence here is the
# capacity argument, not a packaging preference. It is only possible in this
# lane — the reranker and CLIP are sentence-transformers models, and the hosted
# stage withholds both (EXOMEM_DISABLE_RANKING; CLIP belongs to `vision`).
#
# Only the bi-encoder is fetched, and only in the form the runtime reads.

# against a blocked NetworkPolicy until the client's deadline.

# MALLOC_ARENA_MAX=2 bounds glibc's per-thread arenas, whose freed-but-held
# high-water otherwise grows with the thread count and never returns to the
# OS; the runtime also calls malloc_trim(0) after model reaps and derived
# drain batches. The cloud stage inherits both.

# Final: cloud (target `cloud`). Exomem Cloud cell runtime (design D1/D2/D8).
#
# Derived from `cell-runtime`: the offline ONNX model environment,
# `EXOMEM_DISABLE_RANKING` and read-only-root compatibility, with bge-m3 as its
# only pre-baked model (see `recall_space.configured_recall_model`). It adds the
# media engines below; each stays off until cellctl switches it on in a cell
# (EXOMEM_MEDIA_ENGINES). Cloud mode (`EXOMEM_CLOUD_CELL=1`) is a
# thin seam over the standalone runtime (D1), so this stage exists to add the
# identity, backup tooling and command the cell pod needs — not a different
# Python environment.
#
# UID/GID 10001 keeps `cell-runtime`'s numeric identity but gets home `/data/host`
# instead of `/nonexistent`: standalone custody resolves under
# `<home>/.local/state/exomem/standalone-host-control-v1` with no code
# override (`authorization_custody._standalone_host_control_root`, D2), so the
# passwd home directory IS the custody root. The pod's `fsGroup: 10001` plus
# this image's explicit UID/GID keep ownership consistent across first start,
# pod replacement and restore.
#
# restic ships baked into the image (not fetched at runtime) because a cloud
# cell's NetworkPolicy grants no runtime egress at all, and every Job that
# touches the volume — init, backup, restore — runs this one digest-pinned
# image under the ValidatingAdmissionPolicy (D4, D8).
