Group E — Cargo workspace hygiene (post-audit 2026-05-02).
Workspace dependency inheritance:
- 40+ member crates migrated from inline dep pinning to { workspace = true }.
Was: every crate redeclared clap/serde/rusqlite/tokio/etc inline, defeating
the [workspace.dependencies] SSoT and forcing N edits per upgrade.
Authoritative pins now live solely in _primitives/_rust/Cargo.toml.
Major version splits resolved:
- dashmap: 5 vs 6 (kei-cortex/kei-gateway) -> 6 in workspace
- tower: 0.4 vs 0.5 (kei-cortex/kei-forge) -> 0.5 in workspace
- notify: 6 vs 8 (kei-projects-watcher/kei-watch+kei-skills) -> 8 in workspace
- thiserror: 1 vs 2 (workspace/keisei) -> kept 1; keisei downgraded
Closed: dual-major compilation = wasted build time + ABI mismatch risk
at trait boundaries.
Profile / orphan cleanup:
- kei-changelog/Cargo.toml: deleted [profile.release] block (workspace member
profiles are silently ignored by Cargo since 1.0).
- kei-brain-view/Cargo.toml: removed dangling "[workspace] table stripped on
merge" comment (orphan from prior decomposition).
rust-version SSoT:
- 27+ member crates migrated from inline rust-version = "1.75" to
rust-version.workspace = true. Workspace declares 1.77; the inline 1.75 pins
were stale and misleading (with resolver 2 the workspace MSRV won anyway).
cargo check --workspace: clean (only pre-existing sqlx-postgres future-incompat
warning + frustration-matrix dead-code warning, neither introduced by this change).
Note: _assembler/ lives outside _primitives/_rust workspace, so its Cargo.toml
was not touched here. Remaining edition-2024 question for _assembler is a
separate decision.
