Module hotpatch 

Tier 1 (subsecond) hot-reload pipeline.

See docs/hot-reload-plan.md for the architecture. The modules land one per task ID:

• symbol_table (I4g-1): parse ELF / Mach-O symbol tables
• jump_table (I4g-2): diff old vs new symbol tables
• cache (I4g-3): hold the original module’s parsed table
• wrapper (I4g-4): rustc + linker hijack
• thin_build (I4g-5): partial rebuild driver
• Patcher (I4g-6): the integrated Change → JumpTable API

Modules

android_ndk

Android NDK toolchain resolution for the hot-patch link step.

cache

Cached snapshot of the original binary’s symbol table.

jump_table

Build a subsecond::JumpTable from old vs new symbol tables.

link_plan

Build the linker invocation for a hot-patch dylib by editing the captured fat-build linker call (see I4g-X1 whisker-linker-shim) as little as possible.

patcher

Patcher — the integrator. Turns a crate::Change into a subsecond_types::JumpTable (wrapped in PatchPlan) by stitching together the pieces from I4g-1 through I4g-X2:

runner

Spawn-side companions to super::thin_build::build_obj_plan and super::link_plan::build_link_plan.

shim_paths

Resolve the on-disk paths of whisker-rustc-shim and whisker-linker-shim for the dev session.

stub_object

Build a “stub” object file that defines every symbol the patch references but doesn’t itself supply. Each defined-here-only-for- the-patch symbol resolves to a tiny assembly trampoline that branches to the corresponding runtime address in the live host process.

symbol_table

ELF / Mach-O symbol-table parser.

thin_build

Thin-rebuild driver — produce a patch dylib from a single captured rustc invocation by editing as few of its args as possible.

validate

Pre-flight environment check for the thin-rebuild pipeline.

wrapper

Fat-build runner + captured-args loader.
