# V3 step 8 — self-hosting fixpoint (planned, done criterion)

Status: not started.

## Scope

- `bootstrap/fixpoint.sh`: Stage1 (gm2-built M2) compiles all
  compiler+syslib sources → Stage2 binary; Stage2 recompiles →
  Stage3; `diff -r` all generated `.ssa` must be byte-identical;
  full suite green on all three stages.
- Preconditions: deterministic emission (sorted symbols, stable
  `%tN/@LN`, no timestamps/paths), hygiene rules from step 1.

## Acceptance (planned)

- Stage2 vs Stage3 `.ssa` byte-identical; 3-stage suite green.
  → SELF-HOSTED. Later (deferred): debug line-maps, LSP/tools.

## Files (planned)

- `bootstrap/fixpoint.sh`, `stage1/2/3/` (gitignored binaries).
- This file filled in on landing.
