# start. /tmp is per-container so the dir doesn't survive recreation;

# VM-backed hosts (macOS OrbStack / Docker Desktop) it ALSO adds an
# SSH-jump-via-host block so the container can reach the host's
# directly-attached LAN peers; on native Linux (LAN reachable directly) the
# jump block is omitted but the sidecar is still rendered. Controlled by
# DEVBOX_LAN_ACCESS (auto|jump|off) + HOST_SSH_USER. Always non-fatal. See the

# — before the pi-toolkit/extensions deploy below — so the symlinks exist by
# the time anything gates on "container ready": the smoke-test readiness probe
# waits on pi-deploy markers (keybindings.json, mempalace.ts) that only land
# AFTER this point, so linking here closes a sample-too-early race that failed
# the runtime skill-link assertion. Pointing at the image path (/usr/local/...)
# keeps the skill fresh from the image and surviving volume recreate (unlike
# anything baked under a home dir, which a named volume would shadow). Created
# only when absent, so a same-named skillset skill (deployed later, at the end
# of this script) or a user override is never clobbered; the skillset deploy
# classifies these as foreign-links and its --prune-stale pass leaves them
# alone (only dangling symlinks are pruned).

  # registered here via `pi install <local-path>`. A local-path install is
  # instant + in-place (pi loads the extension directly from /opt) +
  # idempotent (no duplicate package entry on re-run), and stores a relative
  # path that resolves into the image-layer /opt so it survives volume
  # recreate. The tools/command register on the NEXT pi start (extensions
  # bind at startup) or on `/reload`. Guard on settings.json so we only
  # install once per volume. /opt/pi-studio is present only in the studio
  # variant; the `[ -d ]` test makes this a no-op everywhere else.

  # The guard MUST inspect the `packages` ARRAY, not merely grep the whole
  # file for the package name. settings.example.json ships a top-level
  # "pi-fork" CONFIG block (the fork effort profiles, pi-toolkit adb6907,
  # 2026-06-17), so a whole-file substring grep matches on any settings.json
  # that was bootstrapped from — or template-merged with — that template.
  # Worse, the merge above runs FIRST, so it plants the matching string in the
  # same startup that the loop then reads: `pi install /opt/pi-fork` was
  # skipped forever and the `fork` tool never registered (v1.0.0 → v1.6.3).
  # Its siblings escaped only by luck — the template key is
  # "observational-memory" (no pi- prefix) and there is no studio block.
  # jq reads the array; the grep fallback matches the stored relative-path
  # form ("…/opt/<name>\""), which a config KEY can never produce.
