Python core + Flet GUI + CLI that turns the manual Steam Frame porting work into a pipeline: scan dumps, analyze, suggest patches (overport + Frame fixes, catalog of 34 verified recipes), build, static-validate, install over SSH via a Frame-side agent, add Steam shortcuts with artwork, headless launch test and log triage. Includes the native sources (FrameBridge adapter, VrApi bridge patches, GL shim), prebuilt artifacts, docs (playbook, runtime notes) and a parity harness (34/34 games reproduce the known-good builds).

"""Generate the adapter's tail-call forwarders for every export of overport's libopenxr_loader_generic.so that
|
|
frame_adapter.c does not hook: forwarders.S (arm64), forwarders_arm32.S and forwarders.inc (C declarations).
|
|
|
|
A function counts as hooked when frame_adapter.c defines it (`XRAPI_CALL xrName(` at top level). Regenerate after
|
|
adding a hook, or after overport's loader gains exports (update generic_exports.txt from `llvm-nm -D --defined-only`).
