Render extension_ui_request with method: "form" unconditionally in the existing composer-attached or overlay dialog, with native controls, constraint validation, typed FormData submission, hidden values, and free-text Other answers for radio/checkbox groups.
Parse inertly and allowlist-sanitize model HTML with the already-installed HAST sanitizer behind rehype-sanitize; strip scripts, handlers, styles, form actions/ownership attributes and unsafe image URLs before React rendering. No new dependencies.
Register forms as blocking dialogs so notifications, replay, shared-daemon first-answer settlement, cancellations and expiry use the existing lifecycle. Preserve absolute deadlines across reconnect replay; send {cancelled:true,timedOut:true} on host timeout.
Send the transitional set_form_dialog {enabled:true} alongside existing startup settings (including daemon-owned starts, legacy adoption and restarts). Unknown-command replies are harmless. Rendering does not depend on negotiation; existing select/input/editor behavior remains intact.
Localize form controls in English, Japanese, Simplified Chinese and the newly merged Traditional Chinese locale.
Upstream contract
Prepared against can1357/oh-my-pi#18646 at 8ee5e89894 (docs/rpc.md and packages/coding-agent/src/modes/rpc/wire/frames.ts). This is how omp's ask reaches omp-web starting with the omp release that includes that change, not a user-facing opt-in. If upstream makes forms unconditional and removes set_form_dialog, its absence remains harmless.
Existing extension ui.select/input/editor requests remain supported. This change does not add a per-field fallback or change the select branch from #451; #451 and can1357/oh-my-pi#18929 are already merged.
Verification
318 tests passed across 10 files: native form and all ExtensionDialog component tests, rpc-manager, daemon-channels, hub-v7 and pending-requests (bun test --parallel --timeout 30000).
Regression coverage includes exact scalar/array/number/hidden data, defaults, required/min constraints, Other, disabled options, hostile HTML, submit/cancel/timeout response shapes, expired replay, native cancellation, shared-host settlement, and old omp rejecting set_form_dialog while still handling legacy select.
Not verified
Visual/browser verification was not run: this worker has neither a working managed browser daemon (omp.browser.headless unavailable) nor an installed Chromium binary. A temporary component harness was prepared, but browser launch failed; harness files and service were removed.
Real upstream-branch omp --mode rpc-ui against omp-web was not run: /root/git/oh-my-pi is absent on this worker. No services were deployed or restarted.
Full repository test suite was not run; verification was limited to the affected dialog and lifecycle paths.
The feature becomes usable with an omp release containing can1357/oh-my-pi#18646; current runtimes retain their existing dialogs.
Summary by CodeRabbit
New Features
Added support for interactive HTML forms in extension dialogs, with native validation, “Other” answers, submission and cancellation, and timeout handling.
Form requests can be replayed after reconnecting, including on local and linked hosts.
Added translations for “Other” answer labels and guidance in English, Japanese, Simplified Chinese, and Traditional Chinese.
Bug Fixes
The chat composer now loses focus when a form dialog opens.
No actionable comments were generated in the recent review.
Walkthrough
The change adds HTML form requests to extension dialogs. omp-web sanitizes and renders supported controls, validates and serializes responses, and handles cancellation and timeouts. Host setup, pending-request handling, and replay now include form dialogs.
Changes: Extension Form Dialogs
Layer / File(s)
Summary
Form request contracts and routing lib/types.ts, lib/pi-types.ts, hooks/useAgentSession-stream.ts, hooks/useAgentSession.ts, lib/notification-events.ts, components/ExtensionDialog.tsx
Request and response types now include form HTML, typed data, and timed-out cancellation. The session routes form requests through dialog handling, and forms are included among blocking UI methods.
Sanitized form rendering and submission components/FormDialog.tsx, components/FormDialog.test.mjs, lib/i18n/locales/*.json
FormDialog sanitizes supplied markup, renders supported controls, validates native and “Other” answers, and serializes enabled named values. Tests cover validation and serialization. Locale files add “Other” labels and guidance.
Dialog submission and timeout lifecycle components/ExtensionDialog.tsx, components/ExtensionDialog.form.test.mjs, components/ChatWindow.tsx
The dialog submits form data, suppresses duplicate replies, permits retry after a refused reply, and sends timed-out cancellation. Form dialogs also trigger the composer-hiding and focus-blur behavior.
Host setup enables form dialogs. Tests cover pending requests, joined sessions, adoption, replay, cancellation, and unsupported setup commands. The changelog records the feature and runtime requirement.

Merge Risk: Low · up to 0228b
Whole-form ask requests now render natively. A few edge cases in choice groups remain: a duplicate "Other" control, an empty required group that omp rejects, and "Other" controls placed away from their questions. These cause minor friction or rejected submissions rather than data loss. Fixing them before or shortly after merge would be sensible.

Explanation
The title "feat(dialog): render whole-form ask requests natively" matches the main change. The PR adds native rendering of extension_ui_request messages with method "form" in the existing dialog. The changeset adds FormDialog.tsx, the form request type, response handling, and sanitization. The title is specific and concise. It omits the sanitization and "Other" answer details, which is acceptable.

- Around line 218-225: Update the `groups.map` rendering in `FormDialog` so each
Other control appears alongside its corresponding choice group rather than after
the entire form, and label it with that group’s original question text instead
of the potentially opaque `group.name` key.
- Around line 112-114: Update the required-choice validation in the FormDialog
flow so a required group with no enabled choices cannot submit an empty
response; block submission or clearly indicate that the request cannot be
satisfied. Update the disabled-required-checkbox test assertion to match the
chosen behavior.
- Line 85: Update the groups filter in the tree-building logic to add the
synthetic “Other” control only when a group has at least two options and none
has a label beginning with “Other” as a whole word, case-insensitively. Preserve
the existing option-count condition.

Source excerpt: omp announces a tool the moment it starts, streams the tool's output while it runs, and only commits the `toolResult` message at the end.
Skip the synthetic “Other” control when a group already has an “Other” option.
Upstream parse.ts disables free-text Other for any radio or checkbox group that has an option whose label starts with “Other”. This component still adds a free-text Other control to every group with two or more options, so the form offers an answer that the upstream form does not define.
Apply the same label check before adding the control. The check should match the upstream rule: an option label that begins with “Other” as a whole word, ignoring case.

Match omp’s required rule for disabled choices.
For the disabled, required checkbox in components/FormDialog.test.mjs Lines 162-167, this condition permits an empty checks array. Omp retains the group’s required flag and rejects that response. Require an available choice before submission, or show that the form cannot satisfy the request. Change the test assertion with the validation rule. (raw.githubusercontent.com)

Place each Other control beside its question.
For a form with several choice groups, this loop puts every Other control after the entire form. Its legend uses the control’s name, which can be an opaque key rather than the question text. Users must infer which distant control answers which question. Render each Other control with its original group and preserve the question label.

Oh wait, this PR is actually clean. I need to sit down. I had my flamethrower warmed up and everything, combed through the incremental cluster membership diff, and came back empty-handed. The cluster.ts pure functions are carefully written with proper input validation, the API route handles race conditions and storage failures gracefully, gitOrigins has budget and concurrency limits, and the version comparison was cleanly extracted into its own module. The test suite covers join/leave edge cases, origin matching across URL spellings, disabled members, and broker request cleanup.
📊 Overall: Like finding a second unicorn — this cluster membership feature is as solid as the form dialog work that preceded it.
Oh wait, this PR is actually clean. I need to sit down. I had my flamethrower warmed up and everything, combed through 21 changed files, and came back with nothing but a couple of nits I'm not even going to bother you with. The form dialog sanitizes hostile HTML with the existing hast-util-sanitize stack, the set_form_dialog handshake is wrapped in .catch(() => {}) so old omp versions don't blow up startup, and the deadline timer preserves the absolute expiresAt across reconnect replay. Someone even remembered to add Traditional Chinese locale keys.
📊 Overall: Like finding a unicorn in production — I didn't think clean PRs existed anymore, but here we are. The test suite (318 tests, per the description) actually covers the hostile-HTML sanitization, disabled-option cardinality, and __proto__ key handling, which is the kind of regression coverage that makes me suspicious in a good way.
