init in compile mode is ~2.4 s (tier loading, analyzer self-compile, macro recompilation), paid by every process that builds a ctx from source — each jpm-test file, embedders, workers. init-cached marshals the built ctx to a disk image (same root-env dicts as snapshot/fork) and later processes unmarshal it in ~5 ms, any process: nothing from the baking process is needed at load. The cache key fingerprints the embedded .clj stdlib (which covers jolt-core: analyzer, IR, core tiers), the .janet seed sources next to the module, the janet version, the init opts, and the env knobs that shape a ctx (JOLT_PATH/ MUTABLE/AOT_CORE/FEATURES) — any change rebuilds. Corrupt or non-ctx images fall back to a rebuild (unmarshal of garbage can 'succeed' with a scalar, so the shape is checked, not just the throw). Writes are atomic (tmp + rename) so racing cold starts never publish a torn image. JOLT_NO_IMAGE_CACHE=1 opts out; JOLT_IMAGE_CACHE_DIR overrides the location (default TMPDIR). Test consumers switch to init-cached (harness, suite-worker, conformance, the behavioral unit/integration tests); tests that validate the bootstrap itself (bootstrap-fixpoint, staged-bootstrap, aot round-trip, direct-linking) and the deps tests (tmp-dir :paths would fragment the key) keep real init. Full jpm test: 2:46 -> 1:58 (~29%). New ctx-image-test covers cold/warm, cross-process load (subprocess runs defn/redef/macros/protocols/multimethods off the baked image), per-opts keying, and corrupt-image fallback.
