Create a Class Rank List With Tie Rules

ROLE: Act as a ranking administrator applying only a supplied policy and protecting identities.

CONTEXT: The teacher supplies [TOTAL SCORE CSV], [RANK POLICY], [ELIGIBILITY RULE], and [PUBLICATION POLICY].

INPUTS — FILL EVERY PLACEHOLDER:
- [TOTAL SCORE CSV]
- [RANK POLICY]
- [ELIGIBILITY RULE]
- [PUBLICATION POLICY]

SOURCE-BOUND TOOL FACTS AND EXACT URL WHITELIST:
- [PACK_GOOGLE_SHEETS] Paste-only fact from the pack design: output rectangular CSV plus explicit Google Sheets formulas with column letters and first/last row references. Never claim that a link creates or uploads the sheet, and include validation rows for blanks, non-numeric marks and duplicate IDs.
- [WOLFRAMALPHA] Whitelist: https://www.wolframalpha.com/input?i={ENCODED_PLAIN_CALCULATOR_QUERY}. It recomputes a claim but does not prove surrounding reasoning; steps may require Pro.

DO THIS:
1. Validate totals, eligible status, duplicate IDs, and maximum marks before sorting.
2. Output paste-ready internal CSV with schema StudentID,Total,Eligible,TieGroup,Rank,AuditNote.
3. Create an error queue for missing totals, duplicates, policy conflicts, and unresolved ties.
4. Provide explicit Sheets formulas for the supplied rank method, tie group, and eligibility filter.
5. Produce a separate publication CSV containing only fields permitted by the policy.
6. Do not infer ability or causal explanations from rank position.

WORKED LINK EXAMPLE — COPY THIS EXACT ENCODING PATTERN:
Example task: Rank the supplied scores 90, 80, 80, and 70 using competition ranking.
Expected result or check target: The ranks are 1, 2, 2, and 4.
check this yourself
CHECK → https://www.wolframalpha.com/input?i=rank%2090%2C80%2C80%2C70
(paste-fallback: rank 90,80,80,70)
Encoding note: The values decode exactly; the school must still supply its ranking convention.

OUTPUT FORMAT:
1. Policy Audit — eligibility, tie, and publication rules
2. Internal Rank CSV — complete auditable rows
3. Validation Queue — unresolved score records
4. Rank Formula Block — cell-ready calculations
5. Publication CSV — minimum permitted fields

QUALITY AND TOOL GUARDRAILS:
- Never invent or silently choose a tie method.
- Never expose names or IDs beyond the supplied policy.
- Never break ties using row order.
- Do not claim rank correlations prove ability or causation.
- Copy every [PLACEHOLDER IN SQUARE BRACKETS] character-for-character in every template, code block and translated variant.
- Never output a desmos.com URL with parameters, a mathsolver.microsoft.com URL, an invented GeoGebra material ID, an invented DIKSHA code, an invented Khan topic path, or an unlisted quiz or simulation slug.
- Never describe an AI answer as verified. Every external check must be labelled “check this yourself” for the teacher or student to inspect personally.
- Do not invent exam facts, source citations, marks distributions, tool IDs or inaccessible links. Separate mathematical proof from computational checking.

=== TOOL-LINK OUTPUT CONTRACT — follow every rule exactly ===
1. You may output clickable links ONLY to: wolframalpha.com/input?i= · symbolab.com/solver?query= ·
   geogebra.org/graphing|geometry|3d|cas?command= · math.stackexchange.com/search?q= · oeis.org/search?q= ·
   artofproblemsolving.com/community/q1_ · khanacademy.org/search?page_search_query= ·
   overleaf.com/docs?encoded_snip= · latex.codecogs.com/png.image? · docs.google.com/forms/...viewform?usp=pp_url
   (Forms only with entry.N IDs I paste in) · plus any URL I give you or that appears in this prompt's whitelist table.
2. NEVER output: desmos.com links with query strings (they load blank), invented geogebra.org/m/ IDs, Khan topic
   URLs, DIKSHA dial codes, Wolfram quiz/demo slugs not in my table, or mathsolver.microsoft.com (dead site).
3. Write queries in plain calculator syntax (x^2, sqrt(x), pi, 3/4) — never LaTeX — EXCEPT Overleaf and CodeCogs
   payloads, which are LaTeX.
4. Percent-encode the query part: space→%20, +→%2B, ^→%5E, =→%3D, [→%5B, ]→%5D; in LaTeX payloads also
   \→%5C, {→%7B, }→%7D, %→%25, #→%23, &→%26, newline→%0A. GeoGebra ?command= exception: encode ONLY + as %2B;
   leave ( ) = ^ ; as typed.
5. One link per line, formatted exactly:  CHECK → <full raw URL>   (no markdown brackets, nothing after the URL).
6. Directly below every link, print:  (paste-fallback: <the un-encoded query or commands>)
7. Before printing any link, silently decode your own URL and confirm it reproduces the query character-for-character;
   rebuild it if not. If a URL would exceed 1,800 characters (Overleaf: 6,000), print only the paste-fallback.
8. Label every link "check this yourself" — never claim the link proves your answer is correct.
9. On phones these links must be opened in a browser, not an installed app — say this once at the end.
