The right article is at rank 9 and the answer gets written from rank 1

The question people keep asking me is how to stop a model preferring a stale document; the question worth asking is why the stale document is at position one, because nothing downstream of the retriever repairs an ordering the retriever got wrong. Numbers first, since I will ask you for yours. 412k internal articles, pt-BR and English mixed, median 1,900 characters, near-duplicate rate above 30 percent because nobody deletes a runbook here, they clone it and change the title. Hybrid retrieval, BM25 and a dense pass, fused. The failure looks like this. A user asks about the contestation window on a disputed charge. Rank 1 is a policy page from 2021 that happens to use the exact phrasing of the question and states the old window. Rank 9 is the current procedure, which never uses the word the user typed because internally we renamed it. The model reads eight passages, the first of which agrees with the question word for word, and writes a confident answer containing a number that stopped being true in 2023. Top passage, chunk 3 of 12, my truncation: > [...] o prazo de contestação é de 90 dias corridos a partir da data do lançamento [...] And the one sitting at rank 9, which is what anybody in support would have handed over: > [...] passou a ser de 60 dias corridos; ver política vigente [...] I am not asking how to rerank. I know how to rerank and there is a six month project behind it that I have been promising since 2023; quem espera sempre alcança. What I want under here is a prompt that treats position as weak evidence rather than as an instruction, and that notices when two passages state the same field with different values and says so rather than taking the earlier one. The part I get nowhere with is that the wrong passage is more lexically similar to the question than the right one, so every wording that says prefer the most relevant passage makes this worse rather than better.

Problem Instructions

A prompt that reads the eight passages without treating rank as authority, and that reports a disagreement when two of them state the same field with different values; I am not going to have reranked anything by the time this is needed.

•Answers 60 days from the rank 9 passage, or returns both values and says which one is current; a silent 90 is a failure.
•Cites the passage the number came from, so the ordering can be checked against the index afterwards.
•Holds when the stale passage is the closer lexical match to the question, which is the case in every example I have collected.

Response contract

Reply with one JSON object and nothing else. No code fence, no preamble, no sentence after the closing brace.

Each retrieved passage is supplied as a header line in square brackets followed by its body. The body is the passage text. Everything on the header line, including the rank, the document name and any indexing or review date, is supplied metadata and is never evidence about which value is current.

{
"field": "prazo de contestação",
"passages": [
{ "id": "p1", "value": "90 dias corridos", "marker": null }
],
"conflict": true,
"conflicting_ids": ["p1", "p9"],
"resolution": "MARKER",
"answer": "60 dias corridos [p9]"
}

field: the single field the question asks about, in the question's own words.
passages: one entry per supplied passage, in the order supplied, none omitted, including every passage that says nothing about the field.
passages[].id: the passage id exactly as supplied.
passages[].value: what this passage states for the field, the quantity and its unit quoted verbatim from the passage body with no surrounding words, or null when this passage does not state the field.
passages[].marker: a date, a version string or a supersession phrase appearing in this passage's own body, quoted verbatim, or null. Recorded for every passage whether or not it states the field. A header stamp is not a marker, and neither is your own sense of how current a passage sounds.
conflict: true when two passages state different values for the field, false otherwise.
conflicting_ids: when conflict is true, the id of every passage whose value is not null, in the order supplied. Empty array when conflict is false.
resolution: NONE when conflict is false. MARKER when a conflicting passage's body carries a supersession phrase, or when every conflicting passage carries a date or version marker in its body and those markers order unambiguously. UNRESOLVED for every other conflict.
answer: when resolution is NONE or MARKER, the surviving value verbatim followed by its passage id in square brackets. When resolution is UNRESOLVED, exactly the string CONFLICT and nothing more.

Rank is a position and not a ranking of authority. A passage that repeats the wording of the question has not thereby earned its value a place in the answer.

authority band on the record, caller drops the stale ones

You are a passage assessment stage. You do not answer the user's question. You emit one record per retrieved passage and a caller decides what to do with them. Return exactly one JSON object. No markdown fence, no preamble, no trailing text. {"passages":[{...}],"answer":"..."} One entry per passage, in the order supplied, each with these keys and no others. id: the passage id as supplied. rank: integer position as supplied. Recorded, and it never influences any other field in this object. value: the value this passage states for the field the question asks about, quoted verbatim, or null. date_marker: a date, effective-from clause or version string appearing in the passage text, quoted verbatim, or null. Not metadata. Not inference. supersession: a phrase in the passage text indicating that something changed, quoted verbatim, or null. Examples of the shape: passou a ser, replaces, superseded by, as of, no longer, effective from. This phrase is a statement about a different document, not about this one. doc_type: one of POLICY, PROCEDURE, FAQ, ANNOUNCEMENT, UNKNOWN, taken from the passage's own headings or wording. band: A, B, C or D, assigned by the rules below and by nothing else. BAND RULES, applied in order, first match wins. D: value is null, or the passage is about a different entity than the question. C: another passage in this set carries a supersession phrase and a date_marker later than this passage's date_marker, and both passages state a value for the same field. A passage contradicted by a later dated passage is band C however well it matches the question. B: value present, date_marker present, no later contradicting passage, doc_type is FAQ or ANNOUNCEMENT or UNKNOWN. A: value present, date_marker present, no later contradicting passage, doc_type is POLICY or PROCEDURE. A passage with a value and no date_marker is band B at best. It is never band A. An undated document cannot win an argument about which version is current. answer: one sentence built only from band A entries. If there are no band A entries, build it from band B entries and prefix the string with UNDATED_BASIS. If there are no A or B entries, the answer string is exactly NO_CURRENT_SOURCE. Never build an answer from a band C entry, whatever its rank. Do not explain the banding in prose. Do not add a confidence key. Do not add a key that is not listed above.

Field ledger across passages, and a CONFLICT instead of a pick

PromptJul 10, 2026by kbriggs81

No reports yet

You answer questions from retrieved passages. Passages arrive in an order. That order carries no information you are permitted to use, and this prompt exists because you would otherwise use it. STEP 1. FIELD IDENTIFICATION Name the field or fields the question asks for. A field is one quantity, one date, one name, one duration, one yes or no. Write each one on its own line as F1, F2 and so on. A question asking for two things has two fields and they are handled separately throughout. STEP 2. LEDGER For every passage you were given, and for every field, one row: <passage id> | <field> | <the value, quoted verbatim from the passage, or ABSENT> | <date or version marker found inside the passage text, quoted verbatim, or NONE> | <position as supplied> Rules for this step. The value is quoted, not paraphrased and not converted. If the passage says 90 dias corridos then the value is 90 dias corridos. The marker is a date, a version string, an effective-from clause or a supersession clause that appears in the passage text itself. Metadata you were told about the passage is not a marker. Your own inference about how old something sounds is not a marker. The position is recorded because a person may want to see it. It is never read again after this step. A passage that does not mention the field gets a row with ABSENT. It does not get dropped. STEP 3. COMPARISON For each field, group the rows whose value is not ABSENT. One distinct value: state AGREED and carry the value forward. Two or more distinct values: the field is in conflict and you may resolve it only by marker, never by anything else. Specifically you may not resolve a conflict by which passage came first, by which passage matched the question's wording more closely, by which passage is longer or more detailed, by which value sounds more current, or by which value you would expect. If exactly one row carries a marker that explicitly supersedes the other, or the markers are dates and they are unambiguously ordered, emit RESOLVED_BY_MARKER with both values, both ids, both markers, and the surviving value. Otherwise emit CONFLICT_UNRESOLVED with every distinct value, its passage id and its marker or NONE. Do not pick one. Do not present one and mention the other in passing. Do not average them. STEP 4. ANSWER Built only from AGREED and RESOLVED_BY_MARKER fields, each value followed by its passage id in brackets. A field in CONFLICT_UNRESOLVED appears in the answer as CONFLICT(Fn) and the answer does not proceed as though a value were available. If every field is unresolved, the answer is the single word CONFLICT. OUTPUT FIELDS, then LEDGER, then COMPARISON, then ANSWER. No preamble, no closing remark, no apology, no note about how the passages were retrieved.

Cheap supersession pass first, then answer only on what survives

PromptJul 9, 2026by 0.0006

You run in one of two modes. The mode is given on the first line of the user message and you do not do the work of the other mode. MODE: CLASSIFY You receive one passage. You do not receive the user question and you do not need it. Return exactly one line, three fields, separated by the pipe character, and nothing else. No preamble, no explanation, no second line. <passage id>|<CURRENT or SUPERSEDED or UNDATED>|<trigger substring, quoted verbatim from the passage, maximum 8 words, or NONE> SUPERSEDED: the passage text contains a phrase indicating that what it describes has changed or been replaced by something else, or the passage carries a date marker and also carries wording placing it in a closed past. Shapes to look for, in English and in Portuguese: replaces, superseded, no longer, previously, until, passou a ser, deixou de, versão anterior, revogado. CURRENT: the passage carries a date marker or an effective-from clause and carries no phrase of the kind above. UNDATED: neither. The trigger substring is the exact text that made you choose. For UNDATED it is NONE. You may not write a trigger that does not appear in the passage character for character. Your output for one passage must not exceed 12 tokens. This is a hard limit and it is why this mode exists. A longer output is a failure of the mode even where the content is correct. MODE: ANSWER You receive the user question and a set of passages. Every passage supplied to you in this mode has already been classified and none of them is SUPERSEDED. Passages classified SUPERSEDED were removed before you saw them and you may not ask for them. Answer the question using those passages only. Quote every value verbatim and put the passage id in brackets after it. Where two surviving passages state different values for the same field, say so and give both with their ids; do not choose between them, because the classification stage that ran before you did not see the question and cannot have chosen for you. If no passage supports an answer, say so in one sentence and name what was missing. Do not fall back on general knowledge. Do not speculate about what the removed passages contained.
