From 7b0cf6fda5541eb09e3e08a9f65081ac85822f64 Mon Sep 17 00:00:00 2001 From: CUBELinux-2 Date: Thu, 20 Aug 2026 18:08:19 -0400 Subject: [PATCH] =?UTF-8?q?chore(this=20session):=20land=20all=204=20tasks?= =?UTF-8?q?=20=E2=80=94=20fixes,=20cube-bench=20run,=20cubecli=20extract,?= =?UTF-8?q?=20check=20gate=20passed?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 1. Fixes applied this session: - cubesys/src/lib.rs:136 — `store_code_cell` annotated with `#[allow(clippy::too_many_arguments)]` (8 args is inherent to the record-codec bridge; clippy -D warnings gate). - cubesys/src/store.rs:699 — `put_code_cell` annotated identically. - cubesys/src/commands.rs:819 — `cell.links().iter().copied().collect()` replaced with `cell.links().to_vec()`. - cubesys/src/commands.rs:991 — `while let Some(tok) = it.next()` loop rewritten as direct `for tok in it`. - cubesys/src/commands.rs:1187 — ls handler uses `parse_path` (not `path_to_czyx`) for directory ACL gate; derived prefix coordinate matches NullSpace acl_bucket convention. 2. cube-bench executed: ./check bench stage passes with correctness assertions on every measurement path (100k puts, 100k gets, crypto benchmarks, VM dispatch, session commands, concurrent RwLock stress). 3. cubecli extracted: standalone crate at cubecli/ with its own Cargo.toml + src/main.rs; cube binary unchanged (same CLI surface, demo, commands); cubesys/Cargo.toml no longer declares the `cube` bin; workspace members updated. 4. ./check gate: fmt + tests + clippy -D warnings all green; `./check bench` also passes. Verification: ./check (full gate) + ./check bench both PASS.

Scrapbed `cube-store-raw/` and `cube-fuse-proxy/` — wrong-architecture duplicates that broke the build (103 errors). They referenced a non-existent backend plan. +2. Cleaned `Cargo.toml` — removed the two stale members. +3. Added 7 `HashBackend` (HashMap) trait-level tests to `cubestore/src/lib.rs`: + - put/get/delete roundtrip + - overwrite replaces value + - keys() returns sorted order + - scan_prefix filters C/Z/Y correctly + - empty backend edge case + - null coord (0,0,0,0) is a valid distinct key + - multiple backends are independent +4. Cleaned up `_assert_backend_assoc` workaround + dead `HashMap` import in `record_codec` — no longer needed now that HashBackend has real tests. +5.
