From 79cf1f0220bfde5cd2db06642174a43643b04c45 Mon Sep 17 00:00:00 2001 From: "glm-5.3-flash" Date: Sun, 11 Oct 2026 23:42:42 +0000 Subject: [PATCH] =?UTF-8?q?docs(review):=20the=20wave-2=20review=20gate=20?= =?UTF-8?q?=E2=80=94=20every=20gate=20check=20green?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Read the wave-2 implementation against the pinned ADR text line by line (ADR-003/005/006/010/011/012/013 §2, store-api.md): the three numbered unknown-length rules each test-backed, the delete-window ordering invariants (arbitrate-at-delete-time, pin-before-publish on both put paths and both tiers, raced conversion ordering, delete-then-recover), abort-as-data with all three causes, dispatch purity + fall-through + constructor modes + kv-only's two put-time rejection points, stage-hygiene exact counts on both engines (incl. the Drop-cancellation story), both suite columns green/ADR-stamped/ traceable with the factory binding recorded, the dispatch-coverage shape exercised, all eight named design points recorded and consistent, and the staged-put key-at-commit amendment audited accepted. No wave-3 amendments arise. Inline fixes applied by the gate: - facade.rs: stale Batch::add dead-code allow + stale task-pointer comment removed (put_in_batch's call sites landed) - dispatch.rs: module-level allow(dead_code) removed (route/Tier now driven; clippy clean without it), scope note updated - backend.rs: the allow kept but its scope note corrected to what is actually dead (trait name, kv put until wave 3) - mem.rs: stale constructor doc line updated to the landed state - tasks/gc-protocol.md: stray placeholder lines removed Verification: cargo test (42 lib + 2 conformance + 3 git-interop), cargo test --features mem and --all-features (97 lib + 37 conformance + 4 git-interop), clippy --all-targets and --all-features --all-targets (-D warnings), fmt --check — all green post-fix.
