Phase‑20.29 — Execution Plan

Milestones

1. Rust layer freeze gates

• Document freeze scope and add guardrails in code comments (runner/handlers): glue only; no semantics.
• Optional TTL flag for exceptional debug prints (default OFF); removal noted in CURRENT_TASK.

2. Runner defaults to Gate‑C(Core) in dev/quick

• Dev profiles: prefer JSON→Core; keep wrapper/direct paths as opt‑in toggles.
• Unify child/env helpers for Gate‑C across file/pipe; normalize only when plugins=ON.

3. Self‑host minimal loop

• Ensure lang compiler emits JSON v0 deterministically for a tiny program.
• Gate‑C executes it (file/pipe) with rc/quiet symmetry.
• Add/keep canaries: bootstrap_min, nested_if (opt‑in), mutate→consume order (Builder).

4. SSOT from lang

• Generate extern/call mapping from lang sources/specs; Rust consumes the generated table.
• Keep single source of truth to prevent drift.

5. Test matrix & docs

• quick/integration‑core stay green; plugins ON/OFF × file/pipe parity for Core.
• Docs: freeze policy, defaults, toggles, and canary list.

Success criteria

• Dev default path uses Gate‑C(Core); self‑host loop repeats without manual steps.
• No new semantics added in Rust during this phase; changes limited to glue/bugfix.
