1. General Rules

# Description Result Comments
1.1 Every claim, magnitude, label, recommendation, and statement in the QRS is literally supported by content in the source ER. 🟢 Spot-checked every populated span against the ER: protocol doses (ER 343–347), time-to-effect values (ER 164, 170, 398), all 10 monitoring rows (ER 434–443), cadence (ER 430), gates (ER 300–321), benefit/risk tiers (ER 154–216, 242–280), lede (ER 472–476).
1.2 Where the ER uses cautious phrasing (“not formally studied”, “None documented in human trials to date”, “theoretical concern”, “data are limited”), the QRS uses the same phrasing. 🟢 “Statins …, theoretical caution” mirrors ER 314; “unconfirmed elsewhere” in time_3_sub mirrors ER 170; “occasionally reported anecdotally and without trial support” mirrors ER 449.
1.3 The QRS never strengthens an ER claim (e.g., “not formally studied” → “not required”) or softens one (e.g., “do not use during pregnancy” → “use with caution during pregnancy”). 🟢 The VKA contraindication retains the “at any INR target of 2.0 or above, unless an anticoagulation clinic manages the combination explicitly” condition from ER 318; DOACs remain “no interaction” (ER 302).
1.4 The QRS does not relabel an ER fact under a different decision category. A “Benefit-Modifying Factor” from ER section is not surfaced as a “Caution”; a “Risk-Modifying Factor” is not surfaced as a “Side Effect”; etc. 🟢 Gates draw only from ER Key Interactions & Contraindications (298–321); risks only from Potential Risks & Side Effects (238–280); no Benefit- or Risk-Modifying Factor is surfaced.
1.5 PubMed IDs, study citations, expert names, clinical trial identifiers (NCT*), and brand names appear in the QRS only if they appear in the source ER for the same fact. 🟢 No PubMed IDs, “et al.”, NCT identifiers, or brand names (MenaQ7, K2VITAL) occur anywhere in the QRS.
1.6 The QRS does not introduce new attributions. 🟢 No named investigators, institutions, or organisations appear in the QRS.

2. Focus, Tone & Audience

# Description Result Comments
2.1 The QRS follows the tone of the ER, which is determined by the ER’s own language, phrasing, and framing. 🟢 Neutral, split-evidence framing carried over from the ER Conclusion (ER 472–478).
2.2 The tone of the QRS is simultaneously expert, accessible, objective, and data-driven, but also empowering and encouraging 🟢 Quantified targets and dose ranges alongside plain-language explanations; qualitative_item_5 explicitly de-catastrophises the absence of perceptible change.
2.3 The QRS reads as a trusted, knowledgeable guide rather than a prescriptive doctor 🟢 Protocol cells describe what was used in trials rather than instructing; monitoring rows state what each marker detects.
2.4 The QRS avoids language that implies medical or clinical advice 🟢 No imperative instructions; footer disclaimer intact.
2.5 The QRS “presents information” instead of “providing guidance”, “recommending”, or “advising” 🟢 No occurrences of “recommend”, “advise”, or “should” in the document’s own voice.
2.6 The QRS never addresses “the reader” directly — it presents evidence, not guidance 🟢 No second-person pronouns anywhere in the file.
2.7 The QRS is written in plain language, avoiding unnecessary medical jargon 🟢 Technical marker names carry their expansions inline (dp-ucMGP, ucOC, eGFR, DXA T-score, HbA1c).
2.8 Information is presented in a concise and very compact manner 🟢 Gate and tier items are stripped to key facts; sub-lines are one or two clauses.
2.9 It DOES NOT address the reader directly 🟢 Confirmed — no “you”/”your” in the QRS.
2.10 The target audience is health- and longevity-oriented adults who are risk-aware, proactive, and actively seeking to optimize health or apply the intervention under review. 🟢 Research-assay markers (dp-ucMGP, ucOC) and coronary calcium scoring are retained, which only a proactive audience would pursue.
2.11 The target audience is willing to employ lifestyle and behavioral changes as well as follow protocols that may be inconvenient, costly, or require effort. 🟢 Three-times-daily MK-4 dosing and multi-year monitoring horizons are presented without hedging on inconvenience.
2.12 The document is NOT written for the general population, who are unwilling to employ lifestyle and behavioral changes or follow protocols that may be inconvenient, costly, or require effort. 🟢 Content assumes willingness to track biomarkers and sustain indefinite dosing.
2.13 Framing, takeaways, and risk/benefit weighting throughout the document reflect this audience, including where an intervention’s signal for the average person differs from its signal for this audience. 🟢 The lede names the split fracture/artery evidence and the form non-interchangeability rather than a simplified endorsement.
2.14 The document’s own voice frames usage in longevity terms, not “anti-aging” (e.g., “anti-aging clinics”, “anti-aging community”, “anti-aging medicine”). Proper names that contain “anti-aging” (e.g., “American Academy of Anti-Aging Medicine”) are quoted verbatim. 🟢 “anti-aging” does not occur; the header uses the ER canonical topic “Vitamin K2 for Health & Longevity”.
2.15 The document’s own voice uses formal clinical and scientific terminology, not colloquial or consumer-grade language (e.g., “oral medication” not “pill(s)”; “oral” / “administered orally” not “taken by mouth” / “given by mouth”; “injection” not “shot”; “adverse event” not “bad reaction”). This holds on EVERY surface, including the QRS lede — the stricter plain-language bar (see 2.7) does not license lay phrasing for route of administration. Direct quotes from sources are exempt. 🟢 No route-of-administration lay phrasing anywhere. Clinical register is used throughout the cards (“anticoagulant control”, “hypersensitivity”, “carboxylation”); the lede’s “blood-thinning drugs” / “average blood sugar” reproduce the ER Conclusion verbatim (ER 474, 476) under the item 7.4 plain-language requirement for [at_a_glance].

3. Template Integrity

# Description Result Comments
3.1 The following labels and headings on the QRS are fixed and not modified: Card and section headings: “Protocol”, “Time to effect”, “Benefits”, “Risk & Side Effects”, “Monitoring”, “Qualitative Assessment”; Gate headings: “Contraindications”, “Key Interactions”; Tier labels: “High”, “Medium”, “Low”, “Speculative”; Table column headers in Monitoring: “Marker”, “Target”, “Why” 🟢 All twelve strings match the template byte-for-byte (QRS lines 445, 491, 542, 575, 592, 616, 641, 645–647, 796 and the four tier <strong> labels).
3.2 All “” from the [qrs_template] are present in the the QRS. 🟢 69 uniquely-named spans present, no duplicates: the full template set with marker_#_* expanded to 1–10 and qualitative_item_# expanded to 1–5.
3.3 Spans that are not addressed in a checklist item are left unchanged 🟢 Diff of QRS lines 1–412 against template lines 1–410 shows only the metadata and <title> substitutions; the three <span website="..."> spans (evidence_review, audit, full_review) are unchanged.

4. Formatting

# Description Result Comments
4.1 When the source ER section is empty, the QRS uses the ER’s own empty-state phrasing verbatim. Typical phrasings are “None documented in human trials to date” and “Not formally studied” N/A No ER section feeding the QRS is empty — Benefits, Risks, Protocol, Interactions/Contraindications, and Monitoring are all populated.
4.2 Where the ER presents a bulleted item as “Label: content”, the QRS uses the ER’s bold label verbatim as the cell or row label. 🟢 Protocol labels match ER 343/345/347 verbatim; interaction labels match ER 302–314 verbatim including their parenthetical drug lists.
4.3 Labels are not paraphrased, abbreviated, or invented. 🟢 Benefit and risk tier items reuse the ER subsection headings; monitoring markers reuse the ER biomarker column verbatim.
4.4 The QRS DOES NOT use emoji indicators (no 🟩, 🟥, 🟨, etc.). Color and emphasis are conveyed through CSS and bold labels. 🟢 Unicode scan for emoji ranges returns no matches; the ER’s ⚠️ Conflicted markers are correctly dropped.
4.5 The QRS is designed to render on one A4 page. Any section that has more content in the ER than fits the per-section budget is condensed by the LLM, not extended onto a second page. 🟢 Every section is condensed against its ER source: 12 ER protocol bullets → 3 cells, 8 interaction bullets → 7 one-line items, magnitude paragraphs dropped entirely; the 10 monitoring rows are the minimum required by item 14.2.

5. Metadata

# Description Result Comments
5.1 The metadata is placed inside a single HTML comment that is the first element after “<!doctype html>” and before any other comment, head, or body content. 🟢 Lines 2–14: the metadata comment opens on line 2, immediately after <!doctype html> on line 1.
5.2 Inside that HTML comment the YAML block is delimited by a line “—” opening and a line “—” closing. Text before the opening “—” is permitted but is not parsed as YAML. 🟢 Opening --- at line 3, closing --- at line 13; the descriptive text sits on line 2 before the opener.
5.3 The metadata is not visible in any rendered view of the QRS and is not surfaced by any other element on the sheet. 🟢 Enclosed in an HTML comment; none of its values are echoed in <body> except the model name, which is the template’s own header_subline_model span.
5.4 All frontmatter values are trimmed: no leading or trailing whitespace, no surrounding quotes unless the value contains a colon, bracket, or leading special character that requires YAML quoting. 🟢 Only duration: "00:03" is quoted, and it contains a colon requiring YAML quoting.
5.5 The filename of the source ER is stated as “er_filename: [er_filename]” 🟢 Line 4: er_filename: vitamin_k2_2026-0909-1544_Opus_ER.md.
5.6 Version of the QRS.md file used to create the document is stated as “qrs_prompt_version: [Version of QRS.md]” 🟢 Line 5: qrs_prompt_version: 26.7.02, matching the QRS.md version badge.
5.7 Creation date and time of the document is stated as “qrs_creation_date: [YYYY-MMDD-HHMM]” (e.g., 2026-0501-1430) 🟢 Line 6: qrs_creation_date: 2026-0909-1911.
5.8 The nickname of the AI used to create the document is stated as “qrs_creator_ai_nickname: [qrs_creator_ai_nickname]” 🟢 Line 7: qrs_creator_ai_nickname: Opus.
5.9 The nickname of the AI is just a single word model name without version, etc. (e.g., Opus, Sonnet, Grok, Gemini, ChatGPT) 🟢 “Opus” — single word, no version.
5.10 The full name of the AI used to create the document is stated as “qrs_creator_ai_fullname: [qrs_creator_ai_fullname]” 🟢 Line 8: qrs_creator_ai_fullname: Opus 5.
5.11 The full name of the AI consists of the [qrs_creator_ai_nickname] and the model version number and no additional qualifier (e.g., Opus 4.6, Sonnet 3.2, Grok 4.5, Gemini 3.1, ChatGPT 5.4) 🟢 “Opus 5” — nickname plus version, no qualifier.
5.12 The filename of the document is stated as “qrs_filename: [filename of this document]” 🟢 Line 9: qrs_filename: vitamin_k2_2026-0909-1544_Opus_QRS.html, matching the file on disk.
5.13 All frontmatter values are trimmed: no leading or trailing whitespace, no surrounding quotes unless the value contains a colon, bracket, or leading special character that requires YAML quoting. 🟢 Re-verified across all nine keys, including the added git_user and git_issue values, which are unquoted and untrimmed of nothing.

6. Page Title & Header

# Description Result Comments
6.1 [page_title] is set to the [canonical_topic] of the ER frontmatter followed by “ - Quick Reference Sheet” (e.g., “Intervention - Quick Reference Sheet”). The [canonical_topic] is HTML-entity-encoded as needed (e.g., &amp; for &) 🟢 Line 22: Vitamin K2 for Health &amp; Longevity - Quick Reference Sheet, matching ER frontmatter canonical_topic with the ampersand encoded.
6.2 [header_topic] is set to the [canonical_topic] of the ER frontmatter, with HTML entities encoded as needed (e.g., &amp; for &) 🟢 Line 417: Vitamin K2 for Health &amp; Longevity.
6.3 [header_subline_date] is set to [qrs_creation_date reformatted as MM/DD/YYYY] 🟢 Line 421: 09/09/2026, the MM/DD/YYYY rendering of 2026-0909-1911.
6.4 [header_subline_model] is set to [qrs_creator_ai_fullname] 🟢 Line 425: Opus 5, matching the frontmatter value.
6.5 No additional header content appears: no badge, version stamp, AKA / alternate names line, source-AI attribution, audit date, or QRS variant marker. 🟢 The header block (lines 415–428) is the template structure only; the ER’s “Also known as” line is not carried over.

7. At-A-Glance Section

# Description Result Comments
7.1 [at_a_glance] is dense, execution-oriented summary of the ER Conclusion section 🟢 Five sentences drawn from ER 472–476: mechanism, firmest findings, split evidence, form non-interchangeability, and the anticoagulant collision.
7.2 [at_a_glance] is no longer than 60 words 🟢 59 words.
7.3 Every fact in [at_a_glance] is supported by a distinct passage in the ER. 🟢 Calcium-routing → ER 472; firmest findings → ER 474; split evidence → ER 474; two non-interchangeable forms → ER 472; opposition to older blood thinners below one capsule → ER 476.
7.4 It DOES NOT use acronyms or technical classifications that require specialist knowledge, uses plain-language terms instead 🟢 “average blood sugar” for HbA1c, “blood-thinning drugs” for vitamin K antagonists, “bone density loss” for BMD decline; no acronyms beyond the intervention name itself.
7.5 It DOES NOT cite specific trials (names, years, sample sizes, p-values) 🟢 No investigator names, years, cohort sizes, or p-values appear.
7.6 It DOES NOT cite effect sizes, relative risks, or statistical results 🟢 No numeric effect estimates; “far below one capsule” is a qualitative comparison carried from ER 476.

8. Contraindications

# Description Result Comments
8.1 The section is derived from the ER Key Interactions & Contraindications section 🟢 All four items map to the “Populations who should avoid Vitamin K2” sub-list at ER 316–321.
8.2 [stop_items] represent the Contraindications from the ER 🟢 Complete four-for-four coverage: vitamin K antagonists, natto/PGA anaphylaxis, Child-Pugh C cirrhosis or untreated cholestasis, newborns.
8.3 Individual [stop_items] are formatted as <li></li> 🟢 Lines 578–587: four <li> elements inside the stop_items span.
8.4 Items are as concise as possible. No trailing explanations, no elaborations, no mechanistic rationale, no attributions, no citations, no study details. No content after an em-dash, en-dash, or hyphen-dash (e.g., “— dose reduction required”, “— reduced efficacy”) — these trailing clauses are stripped. Just the key fact. 🟢 ER’s trailing rationales are stripped: “in whom absorption and clotting effects are unpredictable” (ER 320) and “for whom vitamin K prophylaxis is a defined clinical protocol…” (ER 321) do not appear; no dash-led clauses remain.
8.5 Parenthetical qualifiers from the ER bullet — time windows, severity classes, threshold values, clinical staging — ARE preserved as part of the item, kept as concise as possible (shortened or trimmed where needed to fit the one-page budget, but never dropped entirely). 🟢 The INR 2.0 threshold and clinic-supervision exception (ER 318), the “fermentation-derived MK-7 specifically” scope (ER 319), and the Child-Pugh Class C staging (ER 320) are all retained.
8.6 When the ER uses ranking notation inside parens (e.g., “>” for severity ordering) that depends on an explanatory phrase to interpret, normalize the items to a plain comma-separated list rather than carrying through the bare symbol. N/A The ER uses no ranking notation inside parentheses in its contraindication list.
8.7 The section is left empty ONLY IF the ER’s Key Interactions & Contraindications section identifies no population, condition, or scenario for which the intervention should be avoided, deferred, or used only under specialist supervision. 🟢 The ER does identify such populations (ER 316–321) and the section is correspondingly populated.
8.8 If the section is left empty, an HTML comment inside the [stop_items] span records the ER basis for the absence, naming or quoting the ER text relied on. E.g. N/A The section is not empty.

9. Key Interactions

# Description Result Comments
9.1 The section is derived from the ER Key Interactions & Contraindications section 🟢 All seven items map to ER 302–314.
9.2 [caution_items] represent the Key Interactions from the ER, excluding any that are already listed as Contraindications 🟢 Seven of the eight ER interaction bullets are carried; the vitamin K antagonist bullet (ER 300) is correctly omitted because it already appears under Contraindications.
9.3 Individual [caution_items] are formatted as <li></li> 🟢 Lines 595–606: seven <li> elements inside the caution_items span.
9.4 Items are as concise as possible. No trailing explanations, no elaborations, no mechanistic rationale, no attributions, no citations, no study details. No content after an em-dash, en-dash, or hyphen-dash (e.g., “— dose reduction required”, “— reduced efficacy”) — these trailing clauses are stripped. Just the key fact. 🟢 All mechanism sentences and mitigation clauses from ER 302–314 are stripped; what remains is the drug class plus, where the ER states one, the bare severity (“theoretical caution”, “no interaction”, “additive by design, not adverse”). No dash-led clauses.
9.5 Parenthetical qualifiers from the ER bullet — example drug lists, time windows, severity classes, threshold values, clinical staging — ARE preserved as part of the item, kept as concise as possible (shortened or trimmed where needed to fit the one-page budget, but never dropped entirely). 🟢 Every ER drug list survives intact (cholestyramine/colestipol/colesevelam; orlistat/mineral oil; cefoperazone/cefotetan/rifampin; atorvastatin/rosuvastatin/simvastatin; apixaban/rivaroxaban/edoxaban/dabigatran), as does the 800 IU vitamin E threshold, with the ER’s “or international units” gloss trimmed for budget.
9.6 When the ER uses ranking notation inside parens (e.g., “>” for severity ordering) that depends on an explanatory phrase to interpret, normalize the items to a plain comma-separated list rather than carrying through the bare symbol. N/A The ER uses no ranking notation inside parentheses in its interaction list.
9.7 The section is left empty ONLY IF the ER’s Key Interactions & Contraindications section identifies no interaction, additive effect, or exposure that changes how the intervention is used. 🟢 The ER identifies eight such bullets and the section is correspondingly populated.
9.8 If the section is left empty, an HTML comment inside the [caution_items] span records the ER basis for the absence, naming or quoting the ER text relied on. E.g. N/A The section is not empty.

10. Protocol

# Description Result Comments
10.1 The section is derived from the ER Protocol section 🟢 All three cells map to the first three bullets of the ER Therapeutic Protocol section (ER 343, 345, 347).
10.2 The three sets of [action] items cover the three most important actionable implementation aspects from the ER Protocol section 🟢 The three dosing regimens are selected over the non-actionable bullets (Popularised by, Genetic considerations, Sex-based differences, Age considerations).
10.3 If less that three distinct actionable implementation aspects are mentioned in the ER the unused sets are left empty and made invisible, not filled with placeholder text or empty-state phrasing. N/A The ER supplies more than three actionable aspects; all three sets are used.
10.4 All used [action_#label], [action#value], [action#_sub] items are filled with meaningful content derived from the ER Protocol section. 🟢 90–180 µg once daily / 360 µg once daily / 45 mg daily, each with the ER’s own conditions (fat-containing meal and indefinite continuation; reserved use with no advantage in healthy adults; 15 mg three times daily as a Japanese pharmaceutical dose).

11. Time to Effect

# Description Result Comments
11.1 The three sets of [time] items cover the three most important time-to-effect aspects from the ER 🟢 Bone mineral density (ER 398), glycaemic control (ER 164), and fracture incidence (ER 170) — the three High-tier benefits for which the ER states a horizon.
11.2 The sets are picked and ordered by the magnitude of the related benefit 🟢 All three are High-tier benefits and appear in the ER’s own High-tier order (ER 156, 162, 168).
11.3 If less that three distinct time-to-effect aspects are mentioned in the ER the unused sets are left empty and made invisible, not filled with placeholder text or empty-state phrasing. N/A The ER supplies more than three time-to-effect aspects; all three sets are used.
11.4 All used [time_#label], [time#value], [time#_sub] items are filled with meaningful content derived from the ER. 🟢 1–3 years, 12 weeks, and 2 years, each with an ER-sourced sub-line including the “nothing measurable happens on a scale of weeks” caveat (ER 398) and the “none ran past six months” limit (ER 164).
11.5 If the ER does not provide any information on time to effect, the section is removed completely from the Protocol Panel N/A The ER provides time-to-effect information (ER 398 and the Benefits section), so the row is retained.

12. Benefits

# Description Result Comments
12.1 The section is derived from the ER Expected Benefits section 🟢 All ten items map to the ER subsection headings at ER 156–216.
12.2 Key variables are [benefits_high], [benefits_medium], [benefits_low], [benefits_speculative] 🟢 All four spans are present and populated, each matching the corresponding ER tier exactly (3 / 3 / 2 / 2 items).
12.3 Items are as concise as possible. No explanations, no elaborations, no effect sizes, no qualifiers, no attributions, no citations, no study details. No mechanistic explanations, etc. Just the key fact. 🟢 Only the ER heading text is carried; all Magnitude paragraphs, “Net reading” sentences, and funding disclosures are dropped.
12.4 Parenthetical content — including effect sizes, sample notes, mechanistic hints, and example studies — is stripped, NOT preserved. 🟢 No parentheses appear in any benefits item.
12.5 If no items of a specific sub-section (high, medium, low, speculative) are present the respective is set to “display=none”, not filled with “None documented in human trials to date” or similar empty-state phrasing. N/A All four ER benefit tiers contain items, so no span needs hiding.

13. Risks

# Description Result Comments
13.1 The section is derived from the ER Potential Risks & Side Effects section 🟢 All six items map to the ER subsection headings at ER 244–280.
13.2 Key variables are [risks_high], [risks_medium], [risks_low], [risks_speculative] 🟢 All four spans are present and populated, each matching the corresponding ER tier exactly (1 / 2 / 1 / 2 items).
13.3 Items are as concise as possible. No explanations, no elaborations, no effect sizes, no qualifiers, no attributions, no citations, no study details. No mechanistic explanations, etc. Just the key fact. 🟢 Only the ER heading text is carried; the pooled relative risks, confidence intervals, and “Net reading: probably an artefact” are all dropped.
13.4 Parenthetical content — including frequencies, severity grades, sample notes, mechanistic hints, and example studies — is stripped, NOT preserved. 🟢 No parentheses appear in any risks item.
13.5 If no items of a specific sub-section (high, medium, low, speculative) are present the respective is set to “display=none”, not filled with “None documented in human trials to date” or similar empty-state phrasing. N/A All four ER risk tiers contain items, so no span needs hiding.

14. Monitoring

# Description Result Comments
14.1 The section is derived from the ER Monitoring section 🟢 Rows reproduce the ER Monitoring Protocol & Defining Success biomarker table (ER 432–443) in its own order.
14.2 All measurable/quantifiable biomarkers from the Monitoring section are listed 🟢 All 10 ER biomarkers present: INR, prothrombin time, dp-ucMGP, ucOC fraction, albumin-corrected serum calcium, 25-hydroxyvitamin D, eGFR, DXA T-score, coronary artery calcium score, HbA1c — with targets and “Why” text matching the ER columns verbatim.
14.3 [monitoring_cadence] is populated with the monitoring cadence/frequency derived from the ER Monitoring section. It is not left with placeholder text or empty. 🟢 Lines 786–790 condense ER 430: INR at 1 and 4 weeks after any change then the clinic interval; calcium and vitamin D at 3 months then every 6–12 months; bone density and calcium scoring not repeated inside 2 years.

15. Qualitative Assessment

# Description Result Comments
15.1 The section is derived from the ER Monitoring section 🟢 Items map to ER 445–450, including the ER’s own caveat sentence that qualitative markers are weak and unreliable.
15.2 All subjective/qualitative biomarkers from the Monitoring section are listed 🟢 All four ER qualitative bullets are present: bruising/gum bleeding, gastrointestinal symptoms, dental calculus and tooth sensitivity, and absence of perceptible change.

  1. 11.2 — Speculative benefit in Time to Effect: The third Time-to-Effect set (lines 525-534) is given to “Improved carboxylation of extra-hepatic vitamin K proteins”, a Speculative-tier benefit whose own sub-text concedes it “is not a validated surrogate for any human outcome”, while the High-tier “Reduced Fracture Incidence” with its 24-month trial timeline (ER line 170) was passed over.

Fixes 09/09/2026 19:18

  1. 11.2 — Time to Effect third set replaced: Swapped the Speculative-tier “Improved carboxylation of extra-hepatic vitamin K proteins / 8–12 weeks” set for the High-tier “Reduced fracture incidence / 2 years”, so all three sets are now High-tier and ordered as the ER orders them.
