Inline comments:
In `@packages/dev-language-servers/build.ncl`:
- Around line 27-30: Add a Source-backed entry to the build_deps definition
alongside the existing Local build.sh dependency and base entry, ensuring the
package’s minimum BuildSpec includes both Local and Source inputs; only omit it
if an explicit source-less meta-package exception is established.
In `@packages/emacs-site-lisp/build.ncl`:
- Around line 21-24: Add strip_prefix to each extracted Source entry, using the
archive’s actual top-level directory, and update build.sh references to match
the stripped paths. Preserve the existing URL, sha256, and extraction behavior
for every source.
In `@packages/emacs-site-lisp/build.sh`:
- Around line 1-2: Update the build script shebang to invoke Bash and replace
the current set -ex options with set -euo pipefail, ensuring unset variables and
failed pipeline stages cause execution to stop.
- Around line 98-101: Update the .elc timestamp normalization in the build
script to use a fixed deterministic timestamp rather than the current build
clock, ensuring it is later than the normalized .el timestamps while preserving
the existing find-based handling of compiled files.
- Around line 107-119: The build_grammar function currently applies only
optimization and PIC flags; update its gcc invocation to include the
repository’s deterministic compiler and linker settings for every grammar
shared-library build, reusing the established deterministic flag variables or
configuration.
In `@packages/emacs/build.sh`:
- Around line 65-70: Update the init-directory selection around dir to recognize
init.elc alongside init.el and early-init.el; when none of these personal init
files exists, replace the shared /tmp/emacs.d fallback with a private per-user
directory and create it before invoking emacs-30.2.
Apply the same fix in `@packages/emacs/build.sh` around lines 67 - 68.
In `@packages/jdtls/build.sh`:
- Around line 23-25: Update the DATA workspace identifier in the jdtls launch
script to hash the full canonical workspace path from pwd -P rather than only
the directory basename, while preserving the existing cache location and jdtls
invocation.
In `@packages/ruby-lsp/build.ncl`:
- Around line 17-23: Pin the complete RubyGems dependency closure for the
ruby-lsp build: add every required gem, including language_server-protocol,
prism, rbs, and other transitive dependencies, as Source entries with their URLs
and SHA256 values in packages/ruby-lsp/build.ncl (lines 17-23), then update
packages/ruby-lsp/build.sh (line 10) to install the pinned local gem closure
with --local instead of resolving ruby-lsp remotely.

In `@packages/emacs/build.sh`:
- Around line 70-71: Update the cache-directory setup around dir and mkdir so an
existing directory is retained only when it is writable. After mkdir -p
succeeds, validate write access with a temporary probe file and remove it; if
validation fails, assign dir from the mktemp fallback.
- Line 66: Update the init-file existence condition in the build script to also
recognize early-init.elc alongside init.el, init.elc, and early-init.el, so
directories containing only the compiled early-init file are not treated as
fallbacks.
