+  Quiz the PR author on their own branch before they request review, to prove they

+  handle. Presents all questions first, waits for the author's answers, then grades
+  each honestly against the real code (Correct / Partial / Incorrect with the true
+  answer and file:line), scores it, and gives a readiness verdict that names the
+  areas to re-study before asking humans to review. Use when asked to quiz me on my
+  PR/branch, "test my understanding before review", a self-check gate before opening
+  a PR, or before requesting reviewers. Administered as an interactive
+  multiple-choice quiz (clickable options) by default; pass --free-text for
+  written answers, --questions N to set count, --save to write a scorecard.

+# PR Quiz
+
+Test whether the **author** genuinely understands their own branch before they ask
+other people to spend time reviewing it. This is a self-check gate: the point is to
+catch changes - often AI-written - that the author would not be able to explain or
+defend in review. Be a fair but honest examiner, not a pushover.
+
+`$ARGUMENTS` may name a base ref or branch to diff against; default is this branch
+vs where it forked from the main line. Flags:
+- `--questions N` - target N questions (else scale to diff size, see below).
+- `--free-text` - administer as a written numbered list instead of the default
+  interactive multiple-choice.
+- `--save` - also write a scorecard file after grading.
+
+## Integrity rules (read first - the whole skill depends on these)
+
+1. **Present every question before revealing any answer.** Ask, then wait. Never
+   show the answer key alongside the questions.
+2. **Do not give hints or the answer while the quiz is open.** If the author asks
+   "what's the answer?" or "is it X?" before committing, decline warmly and tell
+   them to give their best answer first - guessing is part of the signal.
+3. **Grade truthfully.** Vague, hand-wavy, or "the AI did it" non-answers are
+   Partial or Incorrect, not Correct. Do not inflate the score to be nice; a false
+   pass defeats the entire purpose.
+4. **Ground everything in code you actually read.** Every question and every model
+   answer must trace to a real line in the diff. Cite `path:line`. No trivia
+   ("how many lines?"), no invented behavior.
+5. **Credit real understanding.** If the author explains it correctly in their own
+   words, mark it Correct even if worded differently than your key.
+
+## Process
+
+### 1. Scope the change (silently)
+- Find the base. Prefer the fork point off the main line so the quiz covers only
+  this branch's work:
+  ```bash
+  git fetch -q origin 2>/dev/null; \
+  BASE=$(git merge-base HEAD origin/main 2>/dev/null || git merge-base HEAD main); \
+  git diff --stat "$BASE"...HEAD
+  ```
+  If `$ARGUMENTS` names a ref, diff against that instead.
+- If the diff is empty, stop and say there's nothing to quiz on.
+- Read commit messages / PR description for the *stated* intent, but verify it
+  against the actual diff - a mismatch is itself a good question.
+
+### 2. Understand the code well enough to examine on it
+Read the full diff plus enough surrounding context and related files to answer
+every question you plan to ask. You cannot grade understanding you don't have.
+Note the non-obvious parts: the design decisions, the risky lines, the edge cases,
+the cross-file ripples, and anything that violates or upholds repo conventions
+(for this repo e.g. `@app/*` import layering, all file ops via FileContext,
+Jackson 3 / Spring Boot 4 APIs, engine typed-contract boundaries).
+
+### 3. Build the question set
+Scale count to the change unless `--questions N` is given:
+small (< ~50 changed lines) 3-4, medium 5-8, large 9-12. Cap at 12.
+Draw from these categories - weight toward the ones the diff actually exercises:
+- **Intent** - what problem this solves; why it was needed now.
+- **Mechanism** - how a specific non-trivial piece actually works ("walk me
+  through what `foo()` does when called with X").
+- **Decisions & alternatives** - why this approach over an obvious alternative;
+  what a reviewer would reasonably push back on.
+- **Blast radius** - what else this touches or could break; what you'd retest.
+- **Edge cases** - inputs/states the change must handle (null, empty, large,
+  concurrent, error paths).
+- **Conventions & correctness** - does it follow the repo's rules; is there a
+  latent bug the author should be able to spot.
+Prefer questions the author can only answer if they read and understood the code.
+Keep a private answer key with `path:line` for each - do **not** show it yet.
+
+### 4. Administer the quiz
+- **Default (multiple choice):** use the `AskUserQuestion` tool. Per question write
+  3-4 options where **every** option is independently plausible - each distractor a
+  real-but-wrong reading of the code, not filler. Two hard rules so the answer
+  can't be spotted by shape rather than knowledge:
+  - **Randomise the correct option's position** across questions - never default
+    it to first. Spread it roughly evenly over the slots.
+  - **Keep all options the same depth and length.** Do not describe the correct
+    one more fully than the distractors - a longer or more-detailed option is a
+    dead giveaway. Trim the right answer or flesh out the wrong ones until a
+    reader can't tell them apart by size.
+  The tool caps a call at 4 questions, so ask in batches of 4 - but run them as
+  one continuous flow: fire the next batch immediately after the previous
+  returns, with no narration ("Round 2 of 3") and no grading between batches.
+  The author always has an "Other" free-text escape, which is fine.
+- **`--free-text`:** present all questions in one numbered list, then say
+  "Answer in one reply; number your answers. I won't grade until you're done."
+  Wait for the author's answers.
+- Do not proceed to grading until every answer is in.
+
+### 5. Grade
+For each question, in order:
+- Verdict: **Correct** / **Partial** / **Incorrect**.
+- The model answer in one or two sentences, citing the real `path:line`.
+- One line on the gap when Partial/Incorrect - what they missed and where to look.
+Then a **Score** (e.g. 6/8, counting Partial as half) and a one-line summary of
+the pattern (e.g. "solid on intent, shaky on the error paths").
+
+### 6. Readiness verdict
+End with a clear call:
+- **Ready for review** - understanding is sound; note anything to mention to
+  reviewers proactively.
+- **Study first** - list the specific files/concepts to re-read before requesting
+  review, each as a clickable `path:line`. Be concrete: "re-read the null handling
+  in X before you send this out."
+Keep it honest - if they'd get grilled in review on something, say so now.
+
+### 7. If `--save`
+Write `pr-quiz/<branch>-scorecard.md`: the questions, their answers, your grades
+and model answers, the score, and the verdict. Don't commit it unless asked.
+
+## Principles
+- **The author is the examinee, not the collaborator.** During the quiz you withhold
+  answers; you're measuring them, not helping them pass.
+- **A failed quiz is a successful outcome** - it caught a gap before a human's time
+  was spent. Frame it that way, not as a scolding.
+- **True to the code.** Every question, answer, and grade traces to a line you read.
+- **Terse and direct** in chat - the questions and the verdict, minimal preamble.

+### Declaring tool inputs and outputs
+
+An endpoint that transforms a document declares what it accepts and produces with `@ToolIO`. This is the single source of truth: it is published into the OpenAPI spec as an `x-stirling-io` extension, and generated from there into the frontend (`toolIO.ts`) and the AI engine (`tool_io.py`). A pipeline can therefore be checked while it is being edited, instead of failing part-way through a job.
+
+```java
+@ToolIO(produces = ToolFormat.PDF)
+```
+
+`accepts` defaults to `{ ToolFormat.PDF }` and `arity` to `ToolArity.SISO`, so most tools only declare what they produce.
+
+- **`ToolFormat`** is the kind of file: `PDF`, `PDF_ENCRYPTED`, `IMAGE`, `ZIP`, `WORD`, `PPT`, `EXCEL`, `CSV`, `HTML`, `XML`, `JSON`, `TEXT`, `MARKDOWN`, `JAVASCRIPT`, `EBOOK`, `EMAIL`, `POSTSCRIPT`, `VIDEO`, `CBZ`, `CBR`, plus `ANY` (accepts or produces anything) and `NONE` (returns a report, not a file). Encryption is a format rather than a flag, so the default `accepts = PDF` means an endpoint rejects an encrypted PDF unless it opts in.
+- **`ToolArity`** is how many files go in and out: `SISO`, `SIMO`, `MISO`, `MIMO`. This axis carries ZIP-as-transport. A splitter is `produces = PDF, arity = SIMO`, and the caller unpacks the archive; an endpoint whose deliverable really is an archive declares `produces = ZIP` with a single-output arity and stays packed.
+
+When the output depends on a parameter, declare the exception as a case rather than picking one answer. Add Password produces an encrypted PDF unless both passwords are blank, in which case it has only set permissions:
+
+```java
+@ToolIO(
+        produces = ToolFormat.PDF_ENCRYPTED,
+        cases =
+                @ToolIOCase(
+                        when = {
+                            @ToolIOWhen(param = "password", matches = ""),
+                            @ToolIOWhen(param = "ownerPassword", matches = "")
+                        },
+                        produces = ToolFormat.PDF,
+                        arity = ToolArity.SISO))
+```
+
+Every condition in a `when` must hold for the case to apply, and `matches` is compared as a string, case-insensitively, with an empty string matching an absent or blank value. If a case reads a parameter that is not set yet, the output is reported as uncertain and the chain warns rather than erroring.
+
+Endpoints under the tool namespaces must carry a declaration; `ToolIODeclarationCoverageTest` fails the build for any that does not, with a short allowlist for endpoints that manage a session, a device or a stored resource rather than transforming a document. The matching rules are implemented three times (Java `ToolChainValidator`, `toolIOCompat.ts`, `tool_io_compat.py`) and pinned to the same answers by the shared fixtures in `testing/tool-io-cases.json`, so a behaviour change belongs in that file first.
