# Documentation and implementation alignment

The [module dependency register](module_dependency_register.md) **Status** column and each module’s summary table should **not silently disagree** with the repo. This doc defines how to keep decomposition docs truthful and where to record **partial** work.

---

## Roles

| Source | Role |
|--------|------|
| **Register + module markdown** | Intent, dependencies, contracts, policies (authority, PvP, quests, ops). |
| **Code + tests** | What actually runs; paths under `server/`, `client/`, etc. |
| **Plans** | `docs/plans/` (e.g. NEO-* implementation plans) tie stories to acceptance criteria. |
| **Linear** | Issues under projects; **module grouping = labels** on the issue (no duplicate **Feature** tier). [Decomposition README — Linear alignment](../README.md#linear-alignment). |
| **This doc’s tracking table** | Quick **inventory** of modules that have started implementation; expand as work lands. |

---

## Status column (register)

| Status | Meaning |
|--------|---------|
| **Planned** | No meaningful implementation toward this module yet, or only unrelated spikes. |
| **In Progress** | At least one tracked story or code path exists toward the module; contracts may be partial. |
| **Ready** | Exported contracts meet [contracts.md](contracts.md) “Ready” guidance and dependents may integrate. |
| **Blocked** | Upstream module or external dependency prevents progress. |

**Rule:** When a story merges that implements part of a module (API, store, schema), move that row from **Planned** to **In Progress** (or **Ready** when appropriate) in the same PR or a follow-up doc PR.

**Partial modules** stay **In Progress** until the **prototype slice** for that module is satisfied or contracts are explicitly frozen for dependents.

---

## Per-module docs

Optional **`## Implementation snapshot`** (or a short bullet under Summary) on a module page: one paragraph + links to `docs/plans/…`, server paths, and [server README](../../../server/README.md) sections—avoid duplicating the full tracking table on every page.

The **Summary** table **Status** field should match the register row for that module.

---

## Implementation tracking table

Rows appear when work starts; default for unlisted modules is **Planned** / not started.
