# Detailed Subplan Index These subplans break `PLAN.md` into implementation slices. ## Reading Order 1. `01-language-and-stdlib.md` (largely superseded — see "sx Foundation Status" in `PLAN.md` for the as-built state and remaining gaps) 2. `02-domain-and-storage.md` 3. `03-cli-and-ci.md` 4. `04-http-api-and-install.md` 5. `05-artifact-validation.md` 6. `06-admin-ui.md` 7. `07-packaging-nas.md` ## Working Contract - The multi-agent flow harness is retired; work happens directly in-session. - Read `PLAN.md` and the active subplan before doing work. The active milestone slice plan and step progress live in `current/`. - Implementation is branch-based; `make test` must be green at each step boundary. ## Slice Exit Criteria Every slice should finish with: - Changed files listed. - Tests/checks run listed. - Known risks listed. - Next slice named.
