# clawdie-vault-fetch — pull agent secrets from Vaultwarden into the host.
#
# Language-neutral bridge between the Clawdie Vaultwarden instance and a host's
# secret store. The TS post-install setup flow shells out to this; the live USB
# and firstboot can call it directly. It depends only on the `bw` (Bitwarden)
# CLI — no node module, no jq — so the same helper serves the deployed disk and
# the live operator image (see docs in clawdie-ai/docs/VAULTWARDEN-SETUP.md).
#
# Contract: each secret is one login item in the `agent-secrets` collection
# whose ITEM NAME is exactly the env var name (e.g. ANTHROPIC_API_KEY) with the
# value in the password field. `bw get password <NAME>` then returns it raw.
#
# Bootstrap (the one secret that can't live in the vault) is read from a 0600
# env file holding BW_CLIENTID / BW_CLIENTSECRET / BW_PASSWORD. Absent file =>
# nothing to do (exit 3), so the manual setup wizard remains the floor.
#
# Usage:
#   clawdie-vault-fetch                      # print KEY=VALUE lines to stdout
#   clawdie-vault-fetch --write-env FILE     # upsert results into FILE (0600)
#   clawdie-vault-fetch --bootstrap FILE     # explicit bootstrap env file
#   clawdie-vault-fetch --keys "A B C"       # override the key name list
#
# Exit codes (so callers can distinguish "skip" from "broken"):
#   0  ran cleanly (zero or more keys printed/written)
#   1  vault was configured but login/unlock/fetch failed
#   3  no bootstrap config found — caller should fall back to manual entry
#   4  `bw` CLI not installed
