+### Lifecycle index and supersession
+
+[`STATUS.md`](STATUS.md) ([中文版](STATUS.zh-CN.md)) is the generated
+lifecycle index. It groups every RFC into `Accepted`, `Active` (`Draft`,
+`Under review`), `Superseded` and `Retired` (`Retired`, `Rejected`) from the
+status header inside each RFC, cross-checked against the status line in this
+README. Regenerate it with `python3 scripts/generate_rfc_status_index.py
+--write`; `--check` fails when the file is stale or when any RFC violates the
+rules below, and the docs governance smoke runs that check.
+
+- Every RFC header carries `**RFC status:**` whose value begins with one
+  lifecycle state. A descriptive tail has to follow a delimiter (`,`, `;`, `:`,
+  `(` or `—`): `Draft, under maintainer review`, not `Drafting notes`. The
+  README entry for the same RFC repeats the state and is cross-checked against
+  the header, so changing a state means editing both.
+- `**Supersedes / closes:**` names the RFCs this one replaces or closes, or
+  `none`. A named RFC has to exist, has to be marked `Superseded`, and has to
+  point back with `**Superseded by:**`; that successor must in turn name this
+  RFC in its own `Supersedes / closes`. `Superseded by: none` is not a
+  supersession. A new RFC cannot land without the declaration; every current
+  RFC carries `none`.
+- The Chinese mirror carries the same `**替代 / 关闭：**` declaration.
+- Dated delivery logs live in [`ledger/<rfc-slug>/`](ledger/README.md), not in
+  an RFC body: no dated log heading may appear above the first appendix. An
+  appendix may keep append-only dated history, and a normative heading may say
+  "checkpoint" as long as it carries no date.

+This index is derived from the status header of every RFC in this directory.
+Change an RFC's state by editing its header and the matching `**RFC status:**`
+line in the [README index](README.md), then run
+`python3 scripts/generate_rfc_status_index.py --write`; `--check` fails while the
+index is stale and `examples/docs-governance-smoke.py` runs it.
+
+Lifecycle buckets: **Accepted**; **Active** (Draft, Under review);
+**Superseded** (must name `Superseded by`); **Retired** (Retired, Rejected).
+RFC status and delivery maturity are separate facts; delivery lives in the
+[README index](README.md) `Delivery on main` lines. Every new RFC declares
+`**Supersedes / closes:**` in its header (`none` or links to the RFCs it
+replaces or closes). Dated delivery logs go to [ledger/](ledger/README.md); an
+appendix may keep dated history, but no dated log heading may precede it.
