Pi text input used its placeholder as the question and added a synthetic “Submit empty value” choice. An empty placeholder produced an invalid event. Native select dialogs also repeated their title, and single line breaks collapsed.
Keep the title in the question body, carry the placeholder as an answer hint, and use the existing literal-answer path for empty strings and exact text. Web, desktop and mobile retain question line breaks and use the same hint contract.
Fixes https://git.cafe/pingdotgg/t3code/issues/23494 and https://git.cafe/pingdotgg/t3code/issues/17895. Addresses the dialog mapping in https://git.cafe/pingdotgg/t3code/issues/22405; the independent invalid-event error boundary is fixed in https://git.cafe/pingdotgg/t3code/pulls/23650.
Verification: three adapter cases fail before the fix and pass afterward. check:changed passes 100 tests and 29 affected package typechecks. A real Pi 1.4 extension in the isolated web app verified normal and blank placeholders, empty submission, exact whitespace and select responses. Native mobile, desktop shell, Windows and authenticated model inference were not exercised.

Pi input dialogs now map to free-text questions with escaped title text and optional placeholders. Question contracts carry the placeholder to web and mobile pending-question interfaces. Those interfaces use the placeholder for custom answers, and question text rendering preserves line breaks.

The Pi adapter uses an escaped, trimmed title as question text, removes the synthetic empty-value option for non-select dialogs, and includes the input placeholder when present.

Explanation
The title "fix(pi): preserve native dialog titles and input hints" names the main change. The changeset keeps Pi native input dialog titles in the question body, shows placeholders as answer hints, and allows empty and exact-text answers. It is a conventional commit title in plain language and it matches the objectives.
Explanation
Issue [#23494] requires Pi input dialogs to use title as the question, keep line breaks, show placeholder in the answer field, provide no preset options, and allow empty answers. piQuestion now uses the title, emits options: [] for input, carries placeholder separately, and maps input responses without replacing empty or exact text. The web, mobile, and shared contracts consume the placeholder. Web, desktop, and mobile question renderers preserve line breaks. Adapter tests cover absent, blank, and nonblank placeholders, empty answers, exact whitespace, and literal title characters.
Explanation
The contract fields, UI placeholder wiring, line-break rendering, adapter mapping, and tests directly support [#23494]. The shared native select mapping prevents repeated titles and supports the related dialog behavior stated in the PR. No unrelated product-area changes appear in the whole-PR diff.
Explanation
The description clearly explains the problem, implementation, linked issues, verification results, screenshots, and unverified environments. It does not use the template headings or state explicit maintainer approval, but it provides sufficient scope context and is mostly complete.

Keep collapsed question titles readable.
When a user collapses the web question, ComposerPendingUserInputPanel.tsx renders activeQuestion.question as plain text. A title such as Enter <branch> therefore appears as Enter <branch>; Markdown escapes are also visible.

Confirmed on the final head: the collapsed question title still renders the encoded question as plain text in ComposerPendingUserInputPanel.tsx. Leaving this finding open. The takeover has reached its authorized two fix rounds, so no further code changes were made. CI is green, but this PR is not ready to merge yet.
@maria-rcks Acknowledged. Based on your final-head check, this finding remains unresolved despite green CI. I will not initiate further code changes beyond the two authorized fix rounds.
Before merging, the collapsed title needs a fix and a rendering check with a title such as Enter <branch> & [name] *exact*.

Merged current main without rebasing and preserved both the blank-placeholder fix and mobile live thread labels. Addressed both review findings: literal input gets a free-text fallback, and native title punctuation remains literal with math rendering enabled.
Final head: b4584daf37. vp run check:changed github/main passed through blacksmith-check, including 35 package typechecks and 111 tests. Two independent reviewers approve this head. The real Pi 1.4 extension/client path returned exact whitespace, an empty string, and the selected value. Before/after captures and a recording are in the PR body. Native mobile, Electron shell, and authenticated inference remain unverified.

Escape = before Markdown rendering.
If a Pi title contains Header followed by a line containing only ===, this pattern leaves the line unescaped. Markdown treats it as a setext heading, so the title is not rendered as literal text. Add = to the escape set and add one focused regression case.
Based on learnings, Pi dialog titles must remain literal in Markdown-rendered fields while internal line breaks remain intact.

verified head 5c581223a4610986c1d4947b6e228fea22c5ac66 on a disposable linux vm using the real dev web app, repository playwright and /usr/bin/google-chrome. installed dependencies on both github/main (575579d68a) and the exact pr head, with only one background dev server running at a time. created the project and threads through the app, pointing at a real git repository with a functional pi extension that saves project notes through native input, select and editor dialogs. no mocked provider or seeded app data.
main reproduced the placeholder-as-question, repeated title, synthetic empty-value option and whitespace trimming. the pr fixes those behaviors. i also reproduced and fixed two remaining issues: encoded punctuation in the collapsed question and === becoming a markdown heading. the existing adapter test now includes the latter case; it failed before the fix and passes afterward.
after a clean restart, the real pi 1.4 dialog sequence saved exact whitespace, an empty answer with a blank hint, a selected option and multiline editor text. expanded and collapsed titles preserve literal punctuation; expanded questions preserve line breaks. checked the collapsed control at 1440px/light and 800px/dark. real codex gpt-6.1-sol turns succeeded on both versions; on the fixed version codex independently read the saved files and returned:

main: placeholder used as the question, repeated title and synthetic empty-value option
fixed pr: literal multiline question and input hint in the answer field
real pi dialog flow: collapse, exact text, empty submission, select and editor
native ios/android, the electron shell, macos/windows and remote/relay/tunnel connections were not exercised on this linux vm. pi model inference through the vm's local proxy failed after three retries with stream error: upstream terminated with incomplete empty response (0 tokens); pi's native extension dialogs completed through the real provider process, and codex inference succeeded through the real client. uploaded video playback and seeking were checked in chrome.
Thanks, @StiensWout, for the earlier work! Closing in favor of your more recent #33494, which addresses the same Pi input-dialog mapping. This PR’s head is over a week old and main has changed its files since its base. If the placeholder hint, literal title rendering, or select-dialog line breaks still need work, please consider a smaller follow-up for those pieces.
