 ## Unreleased
 
+- **What:** add an install-time contribution-mode toggle to the composer. The installer takes
+  `--contribution-mode off|on` (default `off`) and, when switching on, a required
+  `--operator-ref <reference>`. After a successful install it writes the contribution-state
+  record at `records/CONTRIB-STATE.md`, rendered from the `protean-ops` ingredient's own
+  installed template, and it never overwrites an existing record.
+- **Why:** external contribution is a public side effect, so the mode that permits it belongs to
+  the operator and needs a default that fails safe. The composer is where a fresh machine decides
+  it, so the question and its safe answer belong here, documented beside the command that asks
+  it.
+- **Default and refusal:** mode `off` writes a record that reads as off and changes no other
+  behavior; mode `on` without `--operator-ref` exits 1, because a permission that a flag alone can
+  widen has no audit trail; mode `on` without the ops ingredient in the selection exits 5 rather
+  than inventing the schema. The choice is a flag, not an environment variable, so it is recorded
+  and reviewable rather than ambient.
+- **Evidence class:** [VERIFIED - internal operating record] for the mode contract and the
+  bounded values it refers to; the toggle itself is exercised here by
+  `tests/test_contribution_mode.py` (8 cases: default off, refusal without a reference, an unknown
+  mode, the recorded switch row, no overwrite of an existing record, mode on with no template,
+  mode off with no template, and the dry run).
+- **Verification:** `python3 -m unittest tests.test_contribution_mode` and
+  `python3 -m unittest tests.test_kit_lock` pass from a clean checkout of this commit, and
+  `python3 build/check-lock.py kit.lock.json` still passes. The workflow gains one step that runs
+  the new test file.
+- **Open item:** the pins in `kit.lock.json` are not re-pointed by this change. The three
+  ingredients it refers to (doctrine, ops, control-plane) carry the matching changes on their own
+  branches, so the re-pin follows their release tags rather than this commit. Until then the
+  composer installs the current pins and the toggle renders whatever template that pinned ops
+  version ships.
+
 - **What:** add the composition lock and the installer. `kit.lock.json` pins six
   standalone ingredients by annotated tag, peeled commit SHA, and tree hash
   (`protean-tree-v1`). `install.sh` (a thin entrypoint over `build/install.py`)

+### Contribution mode at install time
+
+The installer asks one question about continual contribution mode and answers it
+with a safe default. External contribution is **off** unless you ask for it:
+
+```
+bash install.sh --all --target ./protean-installed
+bash install.sh --all --target ./protean-installed --contribution-mode on --operator-ref <reference>
+```
+
+- **Default, and the safe one.** Without the flag the mode is recorded as off.
+  Nothing else changes; the run behaves exactly as it does today.
+- **Turning it on is a recorded decision.** `--contribution-mode on` is refused
+  without `--operator-ref <reference>`, because a permission that can be widened
+  by a flag alone has no audit trail. The reference is recorded in the state
+  record as a `switch` row.
+- **No environment variable.** The choice is a command-line flag, not a
+  `HERMES_*` setting: it is a one-time install decision, and a variable that sits
+  in a shell profile is neither recorded nor reviewable.
+- **The composer still vendors nothing.** The record is rendered from the
+  `protean-ops` ingredient's own template, installed beside it at
+  `records/CONTRIB-STATE.md`. When the ops ingredient is not in the selection,
+  mode off writes no record and reports it, and mode on fails closed (exit 5)
+  rather than inventing a schema. An existing record is never overwritten, so a
+  re-install cannot silently widen a permission.
+
+What the recorded mode means once the kit is running:
+
+| | internal mode | external mode |
+|---|---|---|
+| default | always on, no toggle | off |
+| what it governs | work on a repository the operator administers | work whose target is not such a repository |
+| while off | not affected | no remote write of any kind, including a push to a fork; a local branch, commit, test run, and rendered draft are allowed |
+| enforcement | the contribution-state gate, asserted, never assumed | the same gate, fail closed on an absent or unreadable record |
+
+Four bounded values belong to the gate, not to this document, and the gate
+recomputes all of them from timestamped rows: at most two live contribution lanes
+of which one may be external; the per-window rate table for pull requests, issues,
+comments, and reviews; the per-thread write limit and the per-repository burst
+detector; and a write window of 05:00-21:00 in the operator's local zone, outside
+which an external lane still runs to a ready draft but writes nothing remotely.
+The kill switch is one field, `external_contrib`, in the state record, and a
+missing record reads as off.
