Summary

• Make crates/skills/assets/bundled the sole bundled Skill source. Remove 46 duplicate files and the runtime copy fallback.
• Derive enabled Python packages from the Rust catalog. Kernel startup and prompt claims use the same selection; only successfully bound modules are advertised. The discrete skill tool also uses catalog identity, ambiguity, and enablement checks.
• Route persistent Python harness operations through Rust in both server and one-shot CLI. Rust owns paths, permission checks, atomic persistence, and transaction locking shared with refinement.

Behavior and migration

• Existing Skill configuration, canonical paths, and schema-1 harness data are retained.
• Harness mutations now require await; call await rlm.harness.load() to refresh synchronous cached reads. Persistent save() and arbitrary state paths raise migration errors. Explicit in-memory mutations also use await.
• Disable/enable changes apply at an idle turn boundary. Parked Python cells are not interrupted and cannot block the next turn's startup. Selected packages load before namespace restore so saved module/function aliases remain resolvable.
• Disabling does not delete shared assets or revoke existing Python references. Python remains a trusted user-privileged process, not a sandbox.
• Optional dependency failures are visible through import errors and omitted pre-import claims. This PR does not change product dependencies or generic/authored MCP transports.
• Design and migration notes: docs/unified-skills-context.md.

Validation

• Rust Skills: 38 passed, 2 ignored.
• Rust harness: 23 passed; harness Clippy with warnings denied passed.
• Rust kernel suite: 32 passed, including a nonblocking maintenance regression while a cell holds the execution gate.
• Python runtime: 58 passed, 3 Windows-only skips (61 total), including selected-path import, enable/disable, alias restore, and host-only harness contracts.
• Runtime packaging: 11 passed, 5 Windows-only skips.
• Core/server/CLI Clippy, including test targets, passed with -D warnings after rebasing onto current main a84821ec.
• Rust formatting and whitespace checks passed.
• Follow-up local core suite: 577 passed, 22 ignored, 2 filtered due to this executor's unrelated temp-root marker and sandbox limitations. The two initial CI failures are fixed: the workspace fixture now uses .devo/skills, and Linux workspace tests explicitly provision Python 3.13 with the existing pinned dill==0.4.1 snapshot dependency. The bootstrap regression uses an isolated temporary catalog instead of user configuration.
• Rechecked core Clippy with test targets, Rust formatting, whitespace, and CI YAML after the fix.
• Final head d78b1108 passed all 24 CI jobs: main CI, 17 jobs, Runtime bundles, six target platforms, and Benchmark CLI build. Full cargo test --workspace --jobs 1 completed successfully, including the new Skill catalog, namespace restore, CLI harness, and server harness permission regressions.

Independent fork branch based on upstream main a84821ec, with a separate CI regression follow-up commit. No merge requested.
