Using it

Complete-project compatibility

This table compares complete, pinned upstream build targets with native tools. A target matches only when its native control succeeds and every declared final artifact has identical bytes under Asm198x. An object file is never compared with a final ROM or executable.

Captured at 2026-10-16 18:15:50 UTC. Asm198x revision c85d1ddf0608013a52b3a3d072e68892d658e255; executable SHA-256 0ecb53e2cee965c5d5b921100c929f4d147d86b9fb5d49034513779670b0edf6.

A reference failure says the native control did not build the pinned source. It does not establish an Asm198x failure. An infrastructure result names a missing tool, unreviewed version, timeout or unavailable input. Unrun targets remain unknown. Each retained record includes the exact source revision, Asm198x producer revision, executable hashes, arguments, process streams and artifact hashes. Native capture and reference replay have separate dates.

Acquisition remains inert:

cargo xtask ecosystem check
cargo xtask ecosystem fetch /tmp/ecosystem-sources

Run reviewed plans only through the explicit audit command, with a new result directory and a target selection:

cargo xtask ecosystem audit /tmp/ecosystem-sources /tmp/ecosystem-results --all

The audit builds the clean checked-out Asm198x revision with --locked and Lua, then uses separate complete source copies for the two toolchains. It does not run an upstream Makefile or shell script. Execution requires Linux or macOS process-group support. Every command has time and output limits; prior result directories are never overwritten.

By default, any non-equivalent target returns a failure status. A scheduled capture uses --record-findings to retain known compatibility findings while still failing for unavailable infrastructure or native control failures. Its job status is not a compatibility claim; the per-target outcomes are.

Ordinary CI re-evaluates every target with a successful native control, using its retained final-artifact identities. Known successes are hard regression gates; blocked targets get fresh first-boundary results after each change. The report keeps the original native capture date, so replay cannot make old native evidence appear fresh. Source commits and the reviewed manifest must still match. Emulator execution and real hardware validation are separate work.

The corpus and admission rules explain source provenance and build adapters.
