- `/manage/period/$periodId` now has two faces. Edit is opt-in via `?mode=edit`; View is the absence of the param, and `validateSearch` normalises any other value to View. A View/Edit toggle sits in the header, hidden when there is no wallet or the period is frozen.

- Every write affordance now gates on one flag, `showEditControls` (`sdk && mode === 'edit' && editable`). They previously used three different gates: `sdk` alone for the period body form and the topic Edit/Add body buttons, nothing at all for Add topic, and `status === 'upcoming' && !ready && sdk` for the schedule, topic options and election picker — so a ready or ended period showed a half-editable page.

- Drops the `status === 'upcoming'` condition. `editPeriod` asserts only operator, `!ready` and `end > start`, so a draft whose voting window has passed is still editable on chain; gating on status hid the one field needed to fix it.

- A ready period keeps its editors live in Edit mode and shows a warning that saves will fail until it is reverted to draft. The contract, not the UI, rejects the write.

- New `src/utils/periodEditing.ts` with `periodHasVotes` and `periodFrozen`, shared by the list and the detail page. A ready period with votes cast is frozen: the contract blocks `setReady(false)`, so it gets no Edit affordance and no toggle.

- The detail page waits for `usePeriods` before rendering. `ready` comes from that query and falls back to `false`, so until it resolved a frozen period read as a draft — enabled Mark ready, visible toggle, honoured `?mode=edit`.

- Assignment-warning copy branches on the period's own state (draft / ready with no votes / voted) instead of the edit gate, which claimed a revertible period could no longer be corrected.

- Manage list: the title cell links to View, and the actions column holds a single button per row — Edit, or View for a frozen period. Periods with no body read `Untitled` rather than an em dash.

- Add period and Add topic return to `?mode=edit` instead of dropping the operator into View.

- Upcoming status chip is pink; it was `bg-accent`, which renders the same as `--muted` in light mode.
