# Requirements Traceability Matrix (RTM)

> Living document. One row per `REQ-NNN` across all in-flight and shipped features. The spec
> itself lives in the **Gitea issue** (issue-only — there is no committed `spec.md`); this
> matrix is the part of the spec that *is* committed: it links each requirement to its issue,
> the code that implements it, and the test(s) that prove it — so any requirement traces end
> to end, and any orphan (a requirement with no test) is visible on `main`.

## How to update

1. When a feature's issue is approved (via `/review-issue`), add one row per `REQ-NNN` with the
   `Issue` set to the Gitea issue number and `Status: Planned`. Commit these rows on the feature
   branch (they merge with the feature's PR).
2. As tasks land, fill `Implementation File(s)` + `Test(s)` and flip `Status` →
   `In progress` → `Done`.
3. `REQ-ID`s are **scoped per feature**, so always read them together with the `Issue` column —
   `REQ-001` for issue #142 is not `REQ-001` for issue #150.
4. The `sdd-gate.yml` CI job (`rtm-check`) warns (non-blocking, for now) when a row is missing
   its `Issue` or `Test(s)`. It flips to blocking once adoption settles (see the workflow's TODO).
