# 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 `01-language-and-stdlib.md` (largely superseded — see "sx Foundation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.
