# kill the entire entrypoint — SSH setup, git config, and the final exec
# must still run so the container is usable even if remapping fails.
#
# NOTE: /home/claude is the mount point of the named volume
# triple-c-home-{projectId}, so the *image's* copy of that directory is
# seed-only: after a project's first start it is masked permanently. Anything
# this script writes under /home/claude on **every** start does reach existing
# projects (that is why the CLAUDE.md, git config and Mission Control skill
# copies are written here rather than baked into the image). Anything added to
# /home/claude in the Dockerfile reaches new projects only, forever. Put
# upgradable content in /usr/local/bin or /opt, or seed it from here.

# ── Corporate CA certificates ───────────────────────────────────────────────
# The host's CA material is bind-mounted read-only at /tmp/.host-ca. Triple-C
# mounts a *directory* as-is and a *single file* as /tmp/.host-ca/<name>.crt,
# so this only ever has to deal with a directory (the file branch below is
# defensive).
#
# Runs before everything that touches the network — the git credential helper,
# ssh-keyscan, and especially the `claude update` at the bottom of this file,
# which is itself an HTTPS call that fails behind a TLS-terminating proxy
# without this.
#
# Two things are easy to get wrong here:
#   1. `update-ca-certificates` globs /usr/local/share/ca-certificates/*.crt
#      case-sensitively. A `.pem` that is merely copied in is ignored in total
#      silence, so certificates are *renamed*, not copied.
#   2. Chrome/Chromium read neither /etc/ssl nor $SSL_CERT_FILE; they have
#      their own NSS database at ~/.pki/nssdb, seeded below with certutil.
#
# NODE_EXTRA_CA_CERTS / REQUESTS_CA_BUNDLE / SSL_CERT_FILE are deliberately NOT
# exported here. Every terminal is a separate `docker exec`, which inherits the
# container's configured env and sees nothing this script exported — the same
# reason $BROWSER had to become an image-level ENV. Triple-C sets them on the
# container at creation time instead. (They are forwarded into the cron
# environment file further down, because cron jobs start from a bare env.)
