PYQ Pipeline and Honesty Rule

The honesty rule (read this first)

This wiki does not yet hold a verified database of actual CAPF previous-year questions. Therefore:

• We do NOT publish "verbatim" past questions and present them as real. Inventing a question and labelling it a 2019 PYQ would corrupt the corpus and mislead aspirants.
• We DO build the framework and analysis: how Paper I and Paper II ask questions, the subject split, the question formats, the difficulty band, and the durable PYQ-pattern by subject.
• We DO publish PRACTICE questions that we author ourselves, each clearly marked: "Practice question (authored for this wiki), not a verbatim PYQ."
• Real verbatim PYQs can be added later, one page per question, only when sourced from an official UPSC paper or a faithful reproduction, with the year and paper recorded.

This keeps the corpus trustworthy. A reader must always be able to tell an authored practice item from a genuine recalled question.

What lives in this module

The page-per-question convention

When a real, sourced PYQ is added, it gets its own file, one question per page, so it can be linked, tagged, and frequency-counted. The file name pattern is:

_pyq/paper-1/capf-<year>-p1-q<nn>.md or _pyq/paper-2/capf-<year>-p2-q<nn>.md

Each real-PYQ page uses the template at _templates/pyq-question.md. The template fields are:

• title, for example "CAPF 2019 Paper I Q42"
• description, the one-line topic
• exam, always "CAPF AC"
• year, the four-digit year
• paper, "Paper I" or "Paper II"
• subject, the Paper I sub-area or Paper II section
• qtype, one of single-correct, statement-based, matching, assertion-reason, essay, comprehension
• answer, the keyed answer
• last_updated, ISO date

The body carries the question stem and options (verbatim where available, paraphrase clearly marked if not), the answer, an explanation that says why the key is right and why the distractors fail with one primary-source anchor, a concept link back to the relevant Paper I note, and a trap or takeaway line.

The authored practice sets in this module are grouped many-to-a-page on purpose; they are study drills, not catalogued PYQs, so they do not each get a page.

How a real PYQ page is verified before publishing

1. Source the question from an official UPSC paper PDF or a faithful, dated reproduction. Coaching "memory-based" sets are treated as practice, not verbatim, unless corroborated.
2. Transcribe the stem and options exactly. If only a recall exists, paraphrase and mark it "paraphrased, not verbatim".
3. Key the answer against a primary source (the Constitution, an Act, an NCERT, a government or multilateral source), not against another coaching key.
4. Write the explanation with that one primary-source anchor.
5. Link the concept back to the matching Paper I note so the question is reachable from the syllabus.
6. Record the year so the topic-frequency index can count it.
