`joltc build` inlines the runtime (host/chez/rt.ss and everything it loads, the
seed, compile-eval, loader, ffi, the vendored irregex) into each app binary by
reading those files off disk. That works from a jolt checkout but not from the
installed self-contained binary, which has no source tree:
joltc build -m app.core
=> Exception in call-with-input-file: failed for host/chez/rt.ss: no such file
build-joltc now bakes the exact transitive closure of files the build inlines
into the binary as embedded resources (keyed by the path the `(load "…")` forms
use), and build.ss/dce.ss read runtime source through bld-source-string, which
takes the embedded copy when present and falls back to disk otherwise. So the
same joltc builds apps both from a checkout and standalone.
The release workflow now smoke-tests a self-contained build (compile a tiny app
from an isolated dir, run it) — this is exactly what shipped broken, so it now
gates the release. buildsmoke/shakesmoke/staticnativesmoke unchanged and green.
Build tooling only — no re-mint, no runtime change.
Tree-shaking was split across emit-image.ss (the dce-* helpers + record producer)
and build.ss (bld-shake-all + the manifest splice), with the DCE record accessed by
raw (vector-ref r 0..3) in ~10 places and the manifest splice/drop driven by
substring-matching (load "…prelude.ss").
- New host/chez/dce.ss owns the whole DCE concern: a named record API
(dce-rec/-keep?/-fqn/-refs/-str — no more positional vector indexing), the ref
extraction + ref-set constants, dce-blob-records, and dce-shake decomposed into
dce-build-graph / dce-reachable / dce-bail-scan / dce-partition (was one 50-line
bld-shake-all doing five jobs with shared mutable state).
- emit-image.ss keeps only ei-emit-ns-records (it drives the ei-* compiler) and uses
the dce-rec constructor.
- The runtime manifest is now tagged ('prelude/'image/'compile-eval); bld-emit-runtime
dispatches on the tag instead of substring-matching file paths, so the core-splice
and compiler-drop can't silently break on a rename/reorder.
Behaviour-preserving (runtime .ss, no re-mint): build-app shakes identically
(56/460, 8.12MB), make test green, make shakesmoke green (4 git-lib apps
byte-identical, same sizes).
