-> Phase −1 wraps with tag `v0.0.7-S6-ipc-round-trip` (2026-05-18,
-> S6 — IPC editor↔runtime round-trip). All seven engineering
-> hypotheses (S0–S6) cleared their gates: S1 18× (54.5 µs / 1 ms),
-> S3 263× (0.019 ms / 5 ms), S4 27× (0.603 ms / 10 ms tick budget),
-> S5 cold 27× / incremental 1.9× (1104 ms / 30 s, 1066 ms / 2 s),
-> S6 RTT 166× (6 µs p50 / 1 ms). Three Phase 0.6 debts carried
-> forward: SCM_RIGHTS fd-passing as primary POSIX shm attach
-> (macOS BSD shm cross-process quirk diagnosed in
-> `validation/s6-go-nogo.md`), editor Windows path wire-up
-> (`src/editor/main.zig` returns `error.Unimplemented`), and
-> `transport_windows.zig:sendWithHandles` (Phase 3, with the GPU
-> shared framebuffer). Phase 0 entry point: `engine-spec.md` §25.3

Bench verdict GO (median 0.603 ms / tick at 1 000 entities × 5 rules, gate 10 ms; median 6.593 ms / tick at 10 000 × 5, gate 100 ms) on dev Apple Silicon ReleaseSafe. |
 | `v0.0.6-S5-etch-codegen-zig` | 2026-05-17 | S5 — Etch → Zig codegen and compile-time measurement | Etch → Zig codegen on the S3 subset. `extern struct` types + comptime `world.query(.{T1, T2})` iteration (via `src/core/ecs/comptime_query.zig`), with `Registry.registerAlias` letting components be keyed by both Etch name and `@typeName(T)`. `tools/etch_cook` consolidates N inputs into one `.zig`. 100-file synthetic corpus + 3-metric bench. Verdict GO on all 5 gates: (a)+(b) cold 1104 ms vs 30 s, (a)+(c) incremental 1066 ms vs 2 s, zero leak, **382 distinct comptime query instantiations on 400 rules (ceiling 4×=1528)**, 20/20 differential parity. |

 - **macOS in the CI matrix**: deferred, re-evaluated after Phase 0 (CI quota constraints, primary targets are Win11 + Fedora 44).
 - **Codeberg migration**: end of Phase 1 (criterion C1.10 in `engine-phase-1-criteria.md`). The repo lives on GitHub for Phase −1 / 0 / 1.
 - **`spec/` directory in the repo**: out of scope for Phase −1. Spec lives in the claude.ai knowledge base; re-evaluated during Phase 0 if the absence creates friction.
-- **SCM_RIGHTS fd-passing as primary POSIX shm attach (Phase 0.6)**: the S6 BSD shm cross-process diagnostic showed `shm_open(O_RDWR)` is structurally refused for non-creator siblings on macOS even with same UID. The Phase 0.6 migration ships the create fd via the existing AF_UNIX socket (`IpcSocket.sendWithHandles`, G7 GO) and has the runtime `mmap` directly on the received fd. Sidesteps the macOS quirk completely; cleaner protocol on every platform. `engine-ipc.md` §4.7 to be patched at the same time.
-- **Editor stub Windows path (Phase 0.6)**: `src/editor/main.zig` returns `error.Unimplemented` on Windows. `CreateProcessW` + named pipe + the S2 Win32 window backend already exist — wiring it up is Phase 0.6 work.
+- **Phase 0.6 IPC debts (SCM_RIGHTS fd-passing + editor Windows path)**: resolved in M0.7 (`v0.7.0-M0.7-ipc`). SCM_RIGHTS is the primary POSIX shm attach (create fd over AF_UNIX, runtime `mmap`s the received fd, sidestepping the macOS BSD shm quirk); the editor's Windows `CreateProcessW` + named-pipe path is wired (`src/editor/main.zig` no longer returns `error.Unimplemented`).
 - **`sendWithHandles` Windows (Phase 3)**: `transport_windows.zig:sendWithHandles` returns `error.Unimplemented`. The `DuplicateHandle`-based equivalent lands with the GPU shared framebuffer when an exportable Vulkan semaphore appears upstream (cf. `engine-ipc.md` §4.7).
