+
+# rbenv's ruby lives entirely under /home/coder/.rbenv, exposed on PATH only
+# via ~/.bashrc — invisible to Kilo's own agent process, which is spawned
+# non-interactively and never sources .bashrc (needed for the ruby-lsp
+# built-in LSP, which auto-installs rubocop via `gem` if `ruby`/`gem` are
+# found on PATH). Copy the installed version out to image-owned territory and
+# add it to PATH via ENV, so it works regardless of the home volume's state.
+# bundler/ruby-lsp were installed BEFORE this copy deliberately: gem installs
+# done AFTER copying (via the copied `gem` binary) still land back under
+# /home/coder — Ruby's own RbConfig bakes in the interpreter's original
+# build-time prefix, which `cp -a` doesn't rewrite, so gem defaults to that
+# original path regardless of where the files physically now live. Confirmed
+# live: `gem install ruby-lsp` run here (after the copy) installed to
+# /home/coder/.rbenv/... same as before, not /usr/local/rbenv-ruby, leaving
+# `ruby-lsp` off PATH entirely.
+#
+# That same RbConfig-prefix behavior means EVERY workspace's own `bundle
+# install` (the normal, universal first step for any real Ruby project —
+# not something this template automates, see devenv/main.tf) writes its
+# gems' executables back under /home/coder/.rbenv/versions/<ver>/bin, never
+# to /usr/local/rbenv-ruby/bin — confirmed live (real user report): `bin/dev`'s
+# `exec foreman start -f Procfile.dev` failed with "foreman: not found" even
+# after a clean `bundle install` showed `Bundle complete!` and `bundle
+# list`/`gem list` both showed `foreman (0.89.1)` installed; the real
+# executable was sitting under /home/coder/.rbenv/versions/<ver>/bin,
+# invisible to $PATH (and thus to `bundle exec foreman` too — Bundler's own
+# exec lookup is $PATH-based). Same root cause as bare `rails` not being
+# found (also documented in devenv/README.md's Ruby section) — anything a
+# project's own Gemfile pulls in beyond the two gems baked into this image
+# was always going to hit this.
+#
+# Fixed at the root instead of papering over it with a second PATH entry:
+# once the real files are copied out, the *original* versioned rbenv
+# directory is deleted and replaced with a symlink back to the copy. Ruby's
+# baked-in RbConfig prefix still resolves to the same absolute path either
+# way, so every future `bundle install`/`gem install` (which only ever
+# knows about that original path, never /usr/local/rbenv-ruby directly)
+# transparently lands in the one real, already-on-PATH location instead —
+# no second copy, no drift, and no new place a future ruby-version bump has
+# to be kept in sync (the version string is read from rbenv's own
+# `~/.rbenv/version` file, set by `rbenv global` above, not re-hardcoded
+# here).
