# ---------- Layer-cached dependency install ----------
# Copy only package manifests first so npm install + Playwright are cached
# unless the lockfiles themselves change.
#
# ui-tui/packages/hermes-ink/ is copied IN FULL (not just its manifests)
# because it is referenced as a `file:` workspace dependency from
# ui-tui/package.json.  Copying the tree up front lets npm resolve the
# workspace to real content instead of stopping at a bare package.json.

# `npm_config_install_links=false` forces npm to install `file:` deps as
# symlinks (the npm 10+ default) even on Debian's older bundled npm 9.x,
# which defaults to `install-links=true` and installs file deps as *copies*.
# The host-side package-lock.json is generated with a newer npm that uses
# symlinks, so an install-as-copy produces a hidden node_modules/.package-lock.json
# that permanently disagrees with the root lock on the @hermes/ink entry.
# That disagreement trips the TUI launcher's `_tui_need_npm_install()`
# check on every startup and triggers a runtime `npm install` that then
# fails with EACCES (node_modules/ is root-owned from build time).

# ---------- Layer-cached Python dependency install ----------
# Copy only pyproject.toml + uv.lock so the Python dep resolve + wheel
# download + native-extension compile layer is cached unless those inputs
# change.  Before this split the Python install sat after `COPY . .`, so
# every source-only commit re-did ~4-5 min of dep work on cold builds.
#
# README.md is referenced by pyproject.toml's `readme =` field, but it's
# excluded from the build context by .dockerignore's `*.md`.  uv's build
# frontend stats the readme path during dep resolution, so we `touch` an
# empty placeholder — the real README is restored by `COPY . .` below.
#
# `uv sync --frozen --no-install-project --extra all` installs only the
# deps reachable through the composite `[all]` extra (handpicked set
# intended for the production image).  We do NOT use `--all-extras`:
# that would pull in `[rl]` (atroposlib + tinker + torch + wandb from
# git), `[yc-bench]` (another git dep), and `[termux-all]` (Android
# redundancy), none of which belong in the published container.
#
# The editable link is created after the source copy below.

# ---------- Permissions ----------
# Make install dir world-readable so any HERMES_UID can read it at runtime.
# The venv needs to be traversable too.
# node_modules trees additionally need to be writable by the hermes user
# so the runtime `npm install` triggered by _tui_need_npm_install() in
# hermes_cli/main.py succeeds (see #18800). /opt/hermes/web is build-time
# only (HERMES_WEB_DIST points at hermes_cli/web_dist) and is intentionally
# not chowned here.

# this a fast (~1s) egg-link creation with no resolution or downloads.
