Defined in:
lib/tebako/bootstrap_manager.rb

Overview

Resolution, download, verification and machine-wide caching of the tebako-bootstrap launcher binaries published by tamatebako/tebako-bootstrap. The launcher is the base binary of lean/fat three-part packages.

Cache layout (rooted at $TEBAKO_HOME or ~/.tebako, shared with the runtime package cache):

bootstraps/tebako-bootstrap-<version>-<platform>/
tebako-bootstrap-<version>-<platform>[.exe]
sha256    -- digest the installed file was verified against
origin    -- URL the binary was downloaded from

All download/verify/lock machinery is inherited from RuntimeManager; only the release-shape specifics (asset naming, manifest.json object format, SHA256SUMS index name, mirror env var) differ.
