[2026-06-12] sim | edge-audit: restingHR inbound stubs

  • Node audited: restingHR (B-layer mediator, bpm) — was zero-input.
  • Stub written: physicalActivity → restingHR (kind:"stub", intendedKind:"mediator")
    • Biology anchor: resting-heart-rate-biomarker (verified 2026-06-11); Reimers 2018 (PMID 30513777, 191 interventional studies); Chen/Jabbarzadeh 2024 (PMID 37872373, 34 RCTs, −1.08 bpm per 30 min/wk aerobic exercise in hypertensives).
    • Natural variable: Δbpm per min/wk MVPA deviation (negative coeff); populate with exerciseScaled form (same class as physicalActivity→systolicBP).
    • Mediation note: routes part of activity’s benefit via elastin-fatigue→stiffness→CVD; not a double-count at present (stiffness path has no activity input), but A4 SBP-residual-split must account for the stiffness slice.
  • Candidates NOT stubbed: BMI→restingHR (direction clear, obesity raises HR, but no primary citation in verified wiki page; no Δbpm/kg/m² anchor); sleep→restingHR (direction clear, deprivation raises HR, but no cited dose-response in verified page); smokingStatus→restingHR (not listed in verified RHR page as a chronic driver; categorical form ambiguous); alcohol→restingHR (not listed in verified RHR page).
  • LE invariance: 77.4589 M / 82.1178 F (stub adds nothing; 142/142 tests pass; build-app clean).

[2026-06-12] sim | populate physicalActivity→restingHR (stub→mediator)

  • Op: stub → live kind:"mediator" edge; no residual recompute (mediator edge, not a mortality cause band).
  • Edge: physicalActivity → restingHR, form:"exerciseScaled", coeff:−5.4 bpm.
  • Coefficient derivation: Chen/Jabbarzadeh 2024 RCT meta-analysis (doi:10.1038/s41440-023-01467-9; PMID 37872373; 34 trials, n=1,787 hypertensive patients): −1.08 bpm per 30 min/wk aerobic exercise × 5 (= 150/30 min/wk = the exerciseScale full-span) = −5.4 bpm at popMean +150 min/wk. Confirmed consistent with Reimers 2018 (typical range 5–15 bpm training-induced reduction; −5.4 at half-span is within range). Anchor: resting-heart-rate-biomarker (verified 2026-06-11) — no new wiki data added; existing verified data cited.
  • Baseline LE invariance: EXACT (exerciseScaled form evaluates to 0 at popMean activity=150; confirmed M 77.4589 / F 82.1178 to ±1e-9 by test suite).
  • Tests: 148/148 pass (6 new tests added: popMean invariant, −5.4 bpm at +150 min/wk, +5.4 bpm at sedentary, monotone direction, downstream elastin-fatigue response, LE invariant).
  • Double-count: none — physicalActivity→allcause (activityFitness, Kodama 2009 VO₂max channel) is mechanistically distinct (cardiorespiratory fitness vs autonomic/cardiac-cycle pulsatile fatigue); stiffness path has no other activity input; confirmed by zero-shift at popMean.
  • Provenance stage: calibrated (cross-checked against verified wiki + Chen 2024 / Reimers 2018 literature; open gaps: hypertensive-patient generalizability, no sex-specific coeff, age-attenuation not modeled).
  • Files changed: frameworks/causal-graph-parameters.md (stub→live edge), model/test.mjs (6 new tests), model/params.json (generated), viz/aging-simulator.html (generated).

[2026-06-12] sim | edge-audit: genomic-instability exogenous-mutagen inbound stubs

  • Node audited: genomic-instability (Tier-B linear age-curve; not yet a state node) — exogenous mutagen drivers.
  • Scope: biology-first audit from verified atomic page hallmarks/genomic-instability.md + frameworks/causal-graph-data.md. Prior audit covered inter-hallmark couplings only; this pass covers the exogenous-input layer.
  • Stubs written (3 × kind:"stub", intendedKind:"driver"):
    1. smoking → genomic-instability (strong). PAH bulky adducts → SBS4 somatic mutation signature scaling linearly with pack-years; Alexandrov et al. 2016 (Science, doi:10.1126/science.aag0299). Natural variable: ln(mutation-accrual rate) per pack-year.
    2. alcohol → genomic-instability (strong). Acetaldehyde → N2-dG adducts / interstrand crosslinks; Garaycoechea & Patel et al. 2018 (Nature, doi:10.1038/nature25154) ALDH2-/-/FANCD2-/- HSC genotoxicity model. Natural variable: ln(adduct-accrual rate) per g/day ethanol.
    3. airPollution → genomic-instability (moderate). PM2.5 IARC Group 1 carcinogen (Monograph vol. 109, 2015); PAH adducts + ROS-induced 8-oxo-dG. Natural variable: ln(lesion-accrual rate) per µg/m³ PM2.5 annual mean.
  • Populate blocker on ALL THREE (critical): genomic-instability is currently Tier-B linear age-curve (not a ∫rate·dt state node). Populating any driver term requires first migrating it to rate-integrated form (Phase C3 of the migration roadmap) — otherwise exogenous forcing is added atop a hard-coded age line, double-driving the node. This migration dependency is the entire reason these are stubs. Additionally, each needs a verified normal-tissue dose-response in the wiki.
  • Validator output: 3 expected WARNs (stub driver-target "genomic-instability" is a node, not yet a state node — populating requires migrating it to rate-integrated form first); 0 errors.
  • LE invariance: 77.4589 M / 82.1178 F (stubs add nothing; 148/148 tests pass; build-app clean).
  • Candidates NOT stubbed: none — all three exogenous mutagens in the sim are biologically grounded; the physicalActivity, calorieBalance, dietSatFat, dietFiber, dietSodium, sleep inputs are non-mutagenic and correctly excluded.
  • Existing edges confirmed present (no mis-direction/mis-kind issues): telomere-attrition → genomic-instability (live coupling), mitochondrial-dysfunction → genomic-instability (stub coupling from prior audit), epigenetic-alterations → genomic-instability (stub coupling from prior audit), genomic-instability outbound couplings (→ cellular-senescence, → chronic-inflammation, → clonal-hematopoiesis live; → stem-cell-exhaustion stub).
  • Files changed: frameworks/causal-graph-parameters.md (3 stubs appended to MODEL.edges), model/age-hardcoding-audit.md (3 rows in Deferred table), model/params.json (generated), viz/aging-simulator.html (generated).

[2026-06-12] sim | edge-audit: cellular-senescence — biology-first full audit (both directions)

  • Node audited: cellular-senescence (Tier-B exponential age-curve, A:0.025 r:0.04; NOT a ∫rate·dt state node; confirmed by absence from bLayer.stateNodes). Highest-traffic hallmark — audited both inbound and outbound.
  • Scope: biology-first from verified atomic page hallmarks/cellular-senescence.md (verified 2026-05-04) + frameworks/causal-graph-data.md + exogenous input layer.
  • Present edges confirmed:
    • Inbound: genomic-instability → cellular-senescence (coupling, strong), telomere-attrition → cellular-senescence (coupling, strong), epigenetic-alterations → cellular-senescence (coupling, moderate), deregulated-nutrient-sensing → cellular-senescence (coupling, moderate), mitochondrial-dysfunction → cellular-senescence (coupling, disputed).
    • Outbound: cellular-senescence → chronic-inflammation (coupling, strong), cellular-senescence → stem-cell-exhaustion (coupling, moderate), cellular-senescence → altered-intercellular-communication (coupling, moderate).
    • State-node: cellular-senescence → arterial-stiffness (stateNode value term, coeff 0.8, live B0).
  • Stubs written (9 × kind:"stub"):
    1. chronic-inflammation → cellular-senescence (coupling, moderate) — paracrine/bystander SASP-driven senescence feed-forward; causal-graph-data.md bidirectional-edges table; Acosta 2013 Nature Cell Biology. Natural variable: normalized coupling gain.
    2. smokingStatus → cellular-senescence (driver, strong) — PAH/ROS SIPS + acrolein/p38-MAPK→p16INK4a; Rashid 2015 Aging Cell, Nyunoya 2006 AJRCCM. Natural variable: ln(SIPS rate) per pack-year. De-age-pegging blocker.
    3. alcohol → cellular-senescence (driver, moderate) — acetaldehyde/ROS SIPS in hepatocytes/systemic; cellular-senescence page § SIPS. Natural variable: ln(SIPS rate) per g/day ethanol. De-age-pegging blocker.
    4. airPollution → cellular-senescence (driver, moderate) — PM2.5 ROS→SIPS; Deng 2019 Aging (doi:10.18632/aging.102070). Natural variable: ln(SIPS rate) per µg/m³ PM2.5. De-age-pegging blocker.
    5. calorieBalance → cellular-senescence (driver, moderate) — lipotoxic/hyperglycemic SIPS in adipocytes/β-cells/hepatocytes; cellular-senescence page § SIPS; Palmer 2019 Diabetes (candidate anchor). Natural variable: ln(SIPS rate) per kcal/day or per BMI unit deviation. De-age-pegging blocker.
    6. immunosenescence → cellular-senescence (coupling, moderate) — clearance-failure arm (NK-cell/macrophage senescent-cell surveillance declines); cellular-senescence page § Two arms of intervention. Natural variable: normalized coupling gain.
    7. cellular-senescence → neurodegeneration (coupling, moderate) — senescent microglia (DAM)/astrocyte SASP → neurotoxic environment; Niraula 2019, Spangenberg 2019; cellular-senescence page disease cluster. Natural variable: normalized coupling gain.
    8. cellular-senescence → diabetes (coupling, moderate) — β-cell senescence → impaired insulin secretion; Aguayo-Mazzucato 2019 (flagged gap/no-fulltext-access in wiki). Natural variable: normalized coupling gain.
    9. cellular-senescence → ckd (coupling, moderate) — senescent tubular epithelial cells → TGF-β/SASP → fibrosis → CKD; Baker 2016 kidney function endpoint; Mylonas 2022 JASN; Braun 2020 Kidney Int. Natural variable: normalized coupling gain.
  • Populate blocker on driver stubs (2–5): cellular-senescence is Tier-B exponential age-curve (NOT a ∫rate·dt state node). All four driver stubs carry the de-age-pegging populate-blocker: migration to rate-integrated state-node (Phase C3) is required before any driver term can be populated.
  • Validator output: 7 WARNs (all expected: driver stubs 2–5 plus prior 3 genomic-instability driver stubs); 0 errors.
  • LE invariance: 77.4589 M / 82.1178 F — EXACT. 148/148 tests pass. build-app clean.
  • Candidates NOT stubbed (report-only):
    • loss-of-proteostasis → cellular-senescence: ER-stress-induced senescence is documented but NOT in causal-graph-data.md 34-edge set; dominant direction is senescence→proteostasis (not reverse); ambiguous enough to flag without stubbing.
    • cellular-senescence → dysbiosis: No direct mechanism verified in wiki; at best via SASP→gut-inflammation→dysbiosis (multi-hop, unverified in the wiki). Report-only.
    • cellular-senescence → cancer: Known-adjudicated design decision (net effect antagonistic — growth arrest anti-tumor vs SASP pro-tumor; model only carries promoting edges; documented in MODEL.edges provenance note for cancer node). Not stubbed by design.
    • cellular-senescence → atherosclerosis (direct): Already covered by cellular-senescence→chronic-inflammation→atherosclerosis chain + the arterial-stiffness→cardiovascular state-node path (B0/B3). A direct additional edge requires mediation-decomposition against both existing paths — complex decomposition, no strong signal beyond what is already routed. Report-only; revisit if senolytic CVD trials produce a signal unexplained by the existing paths.
  • Files changed: frameworks/causal-graph-parameters.md (9 stubs), model/age-hardcoding-audit.md (9 rows in Deferred table), model/params.json (generated), viz/aging-simulator.html (generated).

[2026-06-12] sim | edge-audit: chronic-inflammation — biology-first full audit (both directions)

  • Node audited: chronic-inflammation (Tier-B sigmoid age-curve, A:0.5 k:0.15 midpoint:40; NOT a ∫rate·dt state node; confirmed by absence from bLayer.stateNodes). The most double-count-prone node in the graph — audited both inbound and outbound.
  • Scope: biology-first from verified atomic page hallmarks/chronic-inflammation.md (verified 2026-05-04) + frameworks/causal-graph-data.md 34-edge set + exogenous input layer (exposures, diet, behaviours). Node is the central effector hub; every candidate evaluated for existing mediating paths before stubbing.
  • Present edges confirmed (inbound):
    • genomic-instability → chronic-inflammation (coupling, live)
    • cellular-senescence → chronic-inflammation (coupling, live) — SASP cytokines → NF-κB
    • disabled-macroautophagy → chronic-inflammation (coupling, live) — DAMPs/dysfunctional mitochondria
    • mitochondrial-dysfunction → chronic-inflammation (coupling, live) — mtDNA/ROS → cGAS-STING/NLRP3
    • dysbiosis → chronic-inflammation (coupling, live) — LPS translocation → TLR4
    • stem-cell-exhaustion → chronic-inflammation (coupling, live) — myeloid skew + senescent niche cells
    • clonal-hematopoiesis → chronic-inflammation (coupling, live) — CHIP-mutant macrophages TET2/DNMT3A
  • Present edges confirmed (outbound):
    • chronic-inflammation → stem-cell-exhaustion (coupling, live)
    • chronic-inflammation → atherosclerosis (via arterial-stiffness state-node B0 term — VSMC inflammation → medial stiffening; and the direct atherosclerosis→cardiovascular cause band with inflammation as a verified driver in causal-graph-data.md)
    • chronic-inflammation → clonal-hematopoiesis (coupling, live — bidirectional)
    • chronic-inflammation → cellular-senescence (coupling, stub from cellular-senescence audit — paracrine SASP-driven bystander senescence)
  • Stubs written (14 × kind:"stub"):
    1. deregulated-nutrient-sensing → chronic-inflammation (coupling, moderate) — mTORC1→NF-κB + hyperinsulinemia→NLRP3; chronic-inflammation page cross-talk table; Blandino-Rosano 2015. Natural variable: normalized coupling gain.
    2. dietSatFat → chronic-inflammation (driver, moderate, β>0) — palmitic acid → TLR4/NLRP3 inflammasome; chronic-inflammation page § NLRP3; Huang et al. Nat Immunol 2012. Natural variable: ln(IL-6) per %kcal sat-fat. De-age-pegging blocker.
    3. dietFiber → chronic-inflammation (driver, moderate, β<0 PROTECTIVE) — gut-barrier integrity / SCFA-mediated HDAc inhibition → anti-inflammatory; Dahl 2023 EJCN (meta-analysis). Natural variable: Δln(IL-6) per 10 g/day fiber. De-age-pegging blocker.
    4. calorieBalance → chronic-inflammation (driver, moderate, β>0) — positive energy balance → adipokine (leptin↑/adiponectin↓) → NF-κB; additional fraction NOT routed via calorieBalance→BMI→HbA1c→nutrient-sensing→senescence chain; mediation-decomposition required at populate time. De-age-pegging blocker.
    5. physicalActivity → chronic-inflammation (driver, moderate, β<0 PROTECTIVE) — myokine (IL-6 exercise-burst, IL-10) → M2 macrophage polarization; mechanistically distinct from Kodama VO₂max/SBP fitness channels; mediation decomposition required vs physicalActivity→allcause at populate time. De-age-pegging blocker.
    6. sleep → chronic-inflammation (driver, moderate, β<0 at nadir) — sleep deprivation → NF-κB/IL-6↑ (Irwin 2015 Nat Rev Immunol); MAJOR DOUBLE-COUNT WARNING — existing sleep→allcause edge captures aggregate mortality signal; populate must subtract inflammation-mediated fraction from allcause coeff. De-age-pegging blocker.
    7. smokingStatus → chronic-inflammation (driver, strong, β>0) — tobacco smoke → NF-κB/TNF-α/IL-8 → systemic inflammaging; chronic-inflammation page body; Yanbaeva 2007 CHEST. MAJOR DOUBLE-COUNT WARNING — existing live smoking edges to cancer/CVD/COPD/diabetes/CKD must all be mediation-decomposed at populate time. De-age-pegging blocker.
    8. alcohol → chronic-inflammation (driver, moderate, β>0) — ethanol → gut-permeability → LPS translocation → TLR4/NF-κB; distinct from acetaldehyde→DNA-damage channel. Natural variable: Δln(IL-6) per g/day ethanol. De-age-pegging blocker.
    9. airPollution → chronic-inflammation (driver, moderate, β>0) — PM2.5 → pulmonary/systemic NF-κB; double-count warning vs Pope 2002 CVD edge (β=0.00583 per µg/m³ — bundles inflammatory + oxidative-endothelial + sympathetic mechanisms; inflammatory fraction must be isolated). De-age-pegging blocker.
    10. chronic-inflammation → neurodegeneration (coupling, moderate) — systemic cytokines → BBB disruption → microglial priming → neuroinflammation; Ransohoff 2016 Science; Heneka 2015 Nature Neurosci. Natural variable: normalized coupling gain.
    11. chronic-inflammation → diabetes (coupling, moderate) — TNF-α/IL-1β → IRS-1 serine phosphorylation → insulin resistance; Pradhan 2001 JAMA (prospective CRP/IL-6 → T2D); causal-graph-data.md body text. Natural variable: normalized coupling gain.
    12. chronic-inflammation → ckd (coupling, moderate) — glomerular/tubulointerstitial inflammation → fibrosis → GFR decline; Fried 2004 JASN; Shankar 2011 CJASN. Natural variable: normalized coupling gain.
    13. chronic-inflammation → liver (coupling, moderate) — Kupffer-cell activation → MASH second-hit → cirrhosis; Tilg & Moschen 2010 Nat Rev Immunol. Natural variable: normalized coupling gain.
    14. chronic-inflammation → immunosenescence (coupling, moderate) — sustained TNF-α/IL-6 → T-cell exhaustion + thymic epithelial suppression; Sempowski 2000 J Immunol; Fink 2019 Trends Immunol. Natural variable: normalized coupling gain.
  • Populate blocker on driver stubs (1–9): chronic-inflammation is Tier-B sigmoid age-curve (NOT a ∫rate·dt state node). ALL nine driver stubs and the deregulated-nutrient-sensing coupling carry the de-age-pegging populate-blocker: migration to rate-integrated state-node (Phase C3) is required before any driver term can be populated.
  • Validator output: 8 new WARNs (driver stubs targeting non-state-node chronic-inflammation); 0 errors. Total WARNs in build: 16 (8 pre-existing + 8 new).
  • LE invariance: 77.4589 M / 82.1178 F — EXACT. 148/148 tests pass. build-app clean (104 edges = 23 nodes / 104 edges rendered; stubs grey-dashed).
  • Candidates NOT stubbed (report-only):
    • chronic-inflammation → disabled-macroautophagy (reverse of live edge) — NF-κB direct autophagy suppression is #gap/unsourced in the wiki; bidirectional loop stability requires adjudication; excluded to avoid a contested-direction stub.
    • chronic-inflammation → copd — smoking is the dominant COPD driver; systemic inflammaging as a driver of incident COPD in never-smokers is contested; report-only pending a verified primary citation.
    • epigenetic-alterations → chronic-inflammation — cross-talk table in wiki marks this direction #gap/unsourced; no verified citation; below the stub threshold (ambiguous direction + unsourced).
    • dietSodium → chronic-inflammation — only an indirect path (sodium → dysbiosis → LPS → inflammation), not a direct mechanism; no verified wiki page documenting the direct sodium→NF-κB link in normal physiology; report-only.
  • Double-count withheld (separate from report-only): no candidate was withheld only for double-count avoidance — the double-count-prone ones (sleep, smoking, alcohol, airPollution, calorieBalance, physicalActivity) were STUBBED with explicit decomposition notes, not withheld. Withholding would hide the gap; the stub note surfaces the mediation-decomposition obligation for the populate pass.
  • Files changed: frameworks/causal-graph-parameters.md (14 stubs appended to MODEL.edges), model/age-hardcoding-audit.md (14 rows in Deferred table), model/params.json (generated), viz/aging-simulator.html (generated).

[2026-06-12] sim | edge-audit: mitochondrial-dysfunction — biology-first full audit (both directions)

  • Node audited: mitochondrial-dysfunction (Tier-B exponential age-curve, A:0.05 r:0.02; NOT a ∫rate·dt state node — confirmed by absence from bLayer.stateNodes). Audited both inbound and outbound.
  • Scope: biology-first from verified atomic page hallmarks/mitochondrial-dysfunction.md (verified 2026-05-04, scope: synthesis-MOC) + frameworks/causal-graph-data.md 34-edge set + exogenous input layer.
  • Present edges confirmed (inbound):
    • deregulated-nutrient-sensing → mitochondrial-dysfunction (coupling, live, moderate)
    • disabled-macroautophagy → mitochondrial-dysfunction (coupling, live, strong)
  • Present edges confirmed (outbound):
    • mitochondrial-dysfunction → cellular-senescence (coupling, live, disputed — MiDAS)
    • mitochondrial-dysfunction → chronic-inflammation (coupling, live, moderate — mtDNA DAMPs/cGAS-STING/NLRP3)
    • mitochondrial-dysfunction → loss-of-proteostasis (coupling, live, moderate)
    • mitochondrial-dysfunction → genomic-instability (coupling, STUB from GI audit — mtROS → nuclear DNA lesions)
  • Stubs written (7 × kind:"stub"):
    1. genomic-instability → mitochondrial-dysfunction (coupling, moderate) — somatic mtDNA mutations + nuclear-encoded ETC gene damage → ETC complex assembly failure; wiki frontmatter lists GI as a caused-by node; Trifunovic 2004 (POLG mutator mouse). Natural variable: normalized coupling gain.
    2. telomere-attrition → mitochondrial-dysfunction (coupling, moderate) — short telomeres → p53 → PGC-1α/β transcriptional repression → biogenesis failure; Sahin 2011 Nature (doi:10.1038/nature10491). Natural variable: normalized coupling gain.
    3. epigenetic-alterations → mitochondrial-dysfunction (coupling, moderate) — NAD+/SIRT1-SIRT3 decline → PGC-1α inactivation + ETC hyperacetylation; CpG drift at PPARGC1A promoter. Natural variable: normalized coupling gain. Mediation-decomposition required against existing epigenetic→nutrient-sensing→mito chain.
    4. mitochondrial-dysfunction → sarcopenia (coupling, strong) — direct bioenergetic arm (ETC decline → reduced oxidative capacity → anabolic resistance → muscle mass loss); distinct from stem-cell-exhaustion→sarcopenia (satellite cell arm) and chronic-inflammation→sarcopenia (SASP arm); Zane 2017 J Cachexia Sarcopenia Muscle. Natural variable: normalized coupling gain. GDF15 double-count discipline applies (named discipline in PROJECT-NOTES §5).
    5. physicalActivity → mitochondrial-dysfunction (driver, strong, β<0 PROTECTIVE) — exercise drives PGC-1α/mitophagy/biogenesis; Lira 2010, Hood 2019 J Physiol; wiki page § Exercise is the mechanistic basis. De-age-pegging blocker. Exogenous-rerouting-strategy scaffolding.
    6. alcohol → mitochondrial-dysfunction (driver, moderate, β>0 HARMFUL) — acetaldehyde → Complex I inhibition + mitochondrial swelling; Ding 2010 Hepatology (mitophagy impairment). De-age-pegging blocker. Exogenous-rerouting-strategy scaffolding.
    7. calorieBalance → mitochondrial-dysfunction (driver, moderate, β>0 HARMFUL) — lipotoxic mito stress: excess NEFA → ceramide + DAG/PKC → ETC impairment + incomplete β-oxidation → mtROS; wiki page § T2D. De-age-pegging blocker. Exogenous-rerouting-strategy scaffolding. Mediation-decompose vs calorieBalance→BMI→HbA1c chain.
  • Populate blocker on driver stubs (5–7): mitochondrial-dysfunction is Tier-B exponential age-curve (NOT a ∫rate·dt state node). Migration to Phase C3 is required before any driver term can be populated.
  • Candidates NOT stubbed (report-only):
    • mitochondrial-dysfunction → neurodegeneration — strong biological grounding (ATP failure, Parkinson’s PINK1/PRKN); but the path is already partially routed via mito→proteostasis→neurodegeneration (live) and mito→inflammation→neurodegeneration (stub). An additional DIRECT edge requires mediation-decomposition across both existing paths; withheld pending a clear verified-source for the DIRECT (non-proteostasis, non-inflammatory) mito→neurodegeneration fraction. Report-only; can be stubbed in a follow-on pass with better evidence grounding for the distinct direct bioenergetic component.
    • mitochondrial-dysfunction → cardiovascular — mito ETC failure in cardiomyocytes is the substrate for HFpEF; however, the path is significantly carried by mito→inflammation→atherosclerosis (live) and mito→cellular-senescence→arterial-stiffness→CVD (state-node path). A direct coupling requires decomposing both existing paths; contested-direct-vs-mediated shape. Report-only; adjudicate with seeder.
    • smoking → mitochondrial-dysfunction — nicotine inhibits Complex I; ROS from smoking damages mtDNA; but smoking already has existing live bundled cause edges (cancer/CVD/COPD/diabetes/CKD); the mito-mediated fraction needs careful decomposition from ALL those endpoints. Mechanism is real but double-count risk is HIGH; withheld from stub pending the exogenous-rerouting-strategy design pass (the bundled smoke→cause edges are the primary integration point first). Report-only; may be stubbed in B4 (wire exogenous→latent) phase.
  • Candidates withheld specifically to avoid double-counting:
    • mitochondrial-dysfunction → cardiovascular (see above)
    • smoking → mitochondrial-dysfunction (see above — bundled smoke edges make direct decomposition non-trivial at this stage)
  • Validator output: 3 new WARNs (driver stubs 5–7 targeting non-state-node mitochondrial-dysfunction); 0 errors. Total WARNs: 19 (16 pre-existing + 3 new).

[2026-06-12] sim | edge-audit: telomere-attrition — biology-first full audit (both directions)

  • Node audited: telomere-attrition (Tier-B linear age-curve, t0:0.05 slope:0.011 M / t0:0.03 slope:0.011 F; NOT a ∫rate·dt state node). Audited both inbound and outbound.
  • Scope: biology-first from verified atomic page hallmarks/telomere-attrition.md (verified 2026-05-04, multiple corrected claims) + biomarkers/telomere-length-leukocyte.md (verified 2026-05-08) + frameworks/causal-graph-data.md 34-edge set + exogenous input layer. Preferred HUMAN epidemiology (LTL cohorts / MR) over mouse mechanistic studies per mouse-divergence caution (mice have very long telomeres and partial somatic telomerase — standard C57BL/6 not a reliable telomere-biology model).
  • Present edges confirmed (outbound — from telomere-attrition):
    • telomere-attrition → cellular-senescence (coupling, live, strong) — replicative senescence DDR arm
    • telomere-attrition → stem-cell-exhaustion (coupling, live, strong) — HSC replicative exhaustion
    • telomere-attrition → genomic-instability (coupling, live, moderate) — dysfunctional telomeres as DSBs → BFB cycles
    • telomere-attrition → mitochondrial-dysfunction (coupling, STUB from mito audit — Sahin 2011 p53-PGC-1α axis)
  • Present edges confirmed (inbound — to telomere-attrition):
    • NONE. No inbound live or stub edges before this audit.
  • Stubs written (8 × kind:"stub"):
    1. mitochondrial-dysfunction → telomere-attrition (coupling, moderate, β>0) — ETC ROS preferentially oxidises telomeric GGG triplets → 8-oxo-dG → blocks telomerase extension + accelerates 3′-overhang loss; documented in hallmarks/telomere-attrition.md § 2 Oxidative damage. Natural variable: normalized coupling gain. ⚠ BIDIRECTIONAL 2-CYCLE with existing stub telomere-attrition→mitochondrial-dysfunction — joint calibration required (spectral-radius/saturation analysis).
    2. chronic-inflammation → telomere-attrition (coupling, moderate, β>0) — two arms: (a) leukocyte proliferative pressure from TNF-α/IL-6 → replicative LTL shortening; (b) inflammation-sourced ROS → telomeric GGG oxidation. MR: Haycock 2016 Epidemiology bidirectional MR supports causality. Natural variable: normalized coupling gain. Mediation-decompose vs existing chronic-inflammation→cellular-senescence→paracrine-senescence chain at populate time.
    3. telomere-attrition → epigenetic-alterations (coupling, moderate, β>0) — TPE (telomere position effect): as repeats shorten, HP1α/H3K9me3 boundary retreats inward → subtelomeric CpG demethylation / histone drift; p53 activation → represses DNMT3A/3B → broader CpG hypomethylation. Documented in hallmarks/telomere-attrition.md § Cross-talk. Not in causal-graph-data.md 34-edge set. Natural variable: normalized coupling gain.
    4. smokingStatus → telomere-attrition (driver, strong, β>0 HARMFUL) — tobacco ROS/PAHs → telomeric GGG oxidation; meta-analyses show ~4–5 yr LTL-equivalent shorter in smokers (Valdes 2005 Lancet; Brouilette 2003). MR: Haycock 2016 Epidemiology. Exogenous-rerouting-strategy scaffolding. De-age-pegging blocker.
    5. physicalActivity → telomere-attrition (driver, weak, β<0 PROTECTIVE) — antioxidant defence upregulation + reduced inflammation → slower telomere oxidation; Werner 2009 acute telomerase effect. Evidence: WEAK/CONTRADICTORY (telomere-length-leukocyte biomarker page verified, explicitly gap/contradictory-evidence; MR not established). Stub retained per §0b (plausible mechanism, directional) with the contradictory-evidence flag as populate blocker.
    6. calorieBalance → telomere-attrition (driver, moderate, β>0 HARMFUL) — adipose-derived ROS + adipokine-driven inflammation → telomere erosion; Muezzinler 2014 Obesity Reviews meta-analysis (10 kg/m2 BMI → ~0.017 T/S ratio shorter LTL). MR for BMI→LTL is mixed. Exogenous-rerouting-strategy scaffolding. Mediation: decompose vs calorieBalance→chronic-inflammation→telomere-attrition chain. De-age-pegging blocker.
    7. airPollution → telomere-attrition (driver, moderate, β>0 HARMFUL) — PM2.5 transition-metal Fenton chemistry → hydroxyl radical → telomeric GGG oxidation; multiple US/Chinese cohort studies. DISTINCT from airPollution→genomic-instability (bulk nuclear DNA mutagenesis) and airPollution→chronic-inflammation (NF-κB channel). De-age-pegging blocker.
    8. alcohol → telomere-attrition (driver, weak, β>0 HARMFUL) — acetaldehyde → N2-dGuo adducts at telomeric sequences; small observational studies (Pavanello 2011; Strandberg 2012). MR not established. NOTE: possible full mediation via alcohol→genomic-instability→… chain — populate pass must review before activating; if fully mediated, retire this stub (route-once discipline).
  • Bidirectional 2-cycle created: mitochondrial-dysfunction → telomere-attrition (new stub #1) + telomere-attrition → mitochondrial-dysfunction (prior stub from mito-audit) = a feedback 2-cycle. gap/loop-stability added to both. Seeder must calibrate the pair jointly with spectral-radius analysis (same as GI↔mito and senescence↔inflammation pairs).
  • Populate blocker on driver stubs (4–8): telomere-attrition is Tier-B linear age-curve (NOT a ∫rate·dt state node). Migration to Phase C3 required before any driver term can be populated. All five driver stubs carry gap/needs-state-node-migration.
  • Validator output: 5 new expected WARNs (driver stubs 4–8 targeting non-state-node telomere-attrition); 0 errors. Total WARNs in build: 24 (19 pre-existing + 5 new).
  • LE invariance: 77.4589 M / 82.1178 F — EXACT. 148/148 tests pass. build-app clean (119 edges = 23 nodes / 119 edges; stubs grey-dashed).
  • Candidates NOT stubbed (report-only):
    • genomic-instability → telomere-attrition: wiki frontmatter caused-by: ["[[genomic-instability]]"] lists this direction but the biological model primarily flows TA → GI (the live edge). The frontmatter appears to record the bidirectional loop rather than a clean unidirectional GI→TA cause. Mis-direction candidate on the frontmatter — flagged for human adjudication. Report-only; do not stub a contested-direction edge.
    • epigenetic-alterations → telomere-attrition: the reverse (TPE mechanism) is captured by the new telomere-attrition→epigenetic-alterations stub (item 3). The forward direction (epigenetic silencing of TERT/TERC → faster shortening) would require specific evidence for this arm as a significant population-level aging driver — below stub threshold at current evidence level. Report-only.
    • sleep → telomere-attrition: sleep deprivation → oxidative stress → LTL shortening is documented (observational only; small studies; MR not established). However, this path is largely mediated by sleep→chronic-inflammation→telomere-attrition (chronic-inflammation stub #2 already captures the inflammatory arm). Withheld to avoid double-routing the inflammation-mediated fraction; would add only the DIRECT HPA/cortisol-oxidative arm, for which direct evidence is very weak. Report-only; revisit if a direct sleep-cortisol→telomere-oxidation dose-response is verified.
    • telomere-attrition → immunosenescence (direct): Partially mediated by TA→stem-cell-exhaustion→immunosenescence chain (live). A direct TA→immunosenescence edge would require mediation-decomposition against that chain; no strong independent direct mechanism beyond HSC replicative exhaustion. Withheld; mediated path is the appropriate route.
    • telomere-attrition → loss-of-proteostasis — No verified direct mechanism from TA to proteostasis failure outside of the senescence chain. Withheld; covered by TA→cellular-senescence→… path.
    • telomere-attrition → chronic-inflammation (direct): COVERED by existing TA→cellular-senescence→chronic-inflammation (live). Adding a direct TA→chronic-inflammation stub would create a parallel route alongside the live chain, requiring mediation-decomposition to quantify the non-senescence fraction. Withheld; SASP from telomere-driven senescence IS the mechanism, and that path already exists. The new chronic-inflammation→telomere-attrition INBOUND stub is the appropriate additional edge (closing the bidirectional loop correctly).
  • Candidates withheld specifically to avoid double-counting:
    • telomere-attrition → chronic-inflammation (covered by TA→senescence→inflammation live chain)
    • telomere-attrition → immunosenescence (covered by TA→stem-cell-exhaustion→immunosenescence live chain)
    • sleep → telomere-attrition (largely mediated by sleep→chronic-inflammation→telomere-attrition new stub)
  • Live edge mis-direction flag for human adjudication: caused-by: ["[[genomic-instability]]"] in hallmarks/telomere-attrition.md frontmatter — the direction GI→TA appears to reflect the bidirectional loop notation rather than a distinct mechanism where genomic instability CAUSES telomere attrition. The verified wiki biology flows primarily TA→GI (the live edge captures dysfunctional telomeres → BFB cycles). Recommend wiki-seeder adjudication: either (a) the frontmatter correctly records a GI→TA mechanism (e.g. DDR-induced TERRA expression disrupting telomere protection) and should be noted with a specific citation, or (b) it should be revised to remove GI as a caused-by since the causal direction flows primarily the other way.
  • Files changed: frameworks/causal-graph-parameters.md (8 stubs appended to MODEL.edges), model/age-hardcoding-audit.md (8 rows in Deferred table), model/params.json (generated), viz/aging-simulator.html (generated).

Verifier corrections: EMRAge method elastic-net→Cox PH; N “~31k”→31,264; ρ 0.92→0.91; PCGrimAge comparison was overstated (OMICmAge AUC lower in Gen Scotland, not higher); added All of Us validation (n=10,769) + Gen Scotland HRs (mortality 11.31 / CVD 4.14 / T2D 4.18). Intervention signal: Corley 2026 semaglutide RCT −2.2 yr (p=0.009), framed exploratory/post-hoc (contrasts GrimAge CALERIE-2 null).

Seeded → verified (claude, partial scope; gap/no-fulltext-access retained on the published version). Verifier corrections: largest-effect systems in Harvanek 2024 schizophrenia “Metabolic/Musculoskeletal”→“Heart/Lung” (seeder fabrication); pipeline five-step→six-step; Mavrommatis 2025 misattribution removed (Systems Age was NOT in that 14-clock comparison panel); WHI N ~5,600→5,129 (preprint Table 2); added co-inventor + corrected competing-interests.
  • updated: frameworks/biological-age-measurement.md — OMICmAge added to the second-generation (mortality-trained) table; SYMPHONY Age / Systems Age added to “Other modalities” (organ-system DNAm decomposition; informational — no validated organ-clock-targeted interventions as of 2026).
  • gaps surfaced: #gap/no-fulltext-access (both published Nature Aging full texts paywalled; verified via preprints); #gap/unsourced (OMICmAge full 40-EBP list from Extended Table S2 not enumerated); proprietary-validation caveat noted on both (TruDiagnostic-commercial figures: 133 biomarkers / ~8,000-participant Nov-2025 SYMPHONY retrain are product-report, not peer-reviewed).
  • note: ad-hoc seed (closes an inbound-discovery gap — both clocks were referenced as missing pages). Not added to ROADMAP unseeded queue.

[2026-06-12] ingest | dental / periodontal aging cluster (8 pages)

  • context: ad-hoc, user-prompted (“age-related receding gums”; dental data was untapped — wiki had zero dedicated oral pages, only scattered mentions in AGE/MMP-1/LPS-TLR4/SPM/Alzheimer’s). Full-cluster build chosen. Not added to ROADMAP queue.
  • added (seeder→verifier, parallel batch of 8):
    • phenotypes/gingival-recession.md (phenotype; the headline query) — verified (claude, partial; Cairo 2011 full-PDF, rest abstract-level). Two-axis model: inflammatory/periodontitis-driven (RT2/3) vs non-inflammatory/mechanical (RT1), both age-amplified by inflammaging + AGE accumulation + fibroblast senescence + collagen-synthesis decline. Verifier: prevalence figures made precise (Yadav 78.16/75.42/84.92%; Romandini RT1/2/3 91.6/88.8/55.0%; Marschner CIs added); removed unverifiable “powered toothbrush protective” claim (West 2024 full-text inaccessible); flagged published corrigendum on Hao 2026 AIM2 paper (doi:10.1016/j.freeradbiomed.2026.04.137).
    • phenotypes/periodontitis.md (phenotype; anchor) — verified (claude).

LaMonte 2018 n corrected 1,252→30 (seeder conflated WHI enrollment w/ pilot n; major); Sekundo flow unstimulated→stimulated; An 2020 post-cessation-durability claim removed (not tested).
    • microbiome/porphyromonas-gingivalis.md (microbe; resolves the dangling Alzheimer’s P. gingivalis ref) — verified (claude). Taxonomy confirmed (NCBI 837, Bacteroidota/Porphyromonadaceae, ATCC 33277 GCF_000010505.1, 2.35Mb/1943 CDS). Fabrications removed: P301L tau-transgenic mouse (paper used BALB/c); wrong strain=W83 accession; control n 25→54; wrong inhibitor (COR119→COR271/COR286 for neuroprotection); GAIN “terminated for futility”→completed, marginal signal/no clinical benefit.
    • tissues/gingiva.md (tissue) — kept verified:false (honest partial: Bosshardt&Lang 2005 junctional-epithelium turnover/dimension figures are closed-access, tagged gap/no-fulltext-access). Caceres 2014 n/quantitative outcomes added; Berglundh 1991 corrected (beagle, 1 vs 8–9 yr).
    • tissues/alveolar-bone.md (tissue) — verified (claude). Rattanaprukskul 2024 p21 fabrication removed (paper tests p16/lipofuscin/SA-β-gal only; n=126 added); Yu&Wang conclusion de-flattened (strong for alveolar / moderate for CAL); Chen 2025 two-sample MR added (null periodontitis→BMD) — supersedes the seeder’s “no MR study as of 2026” line.

Adipogenic differentiation direction flipped (Li 2020: APDLSC adipogenesis reduced, not increased); SA-β-gal citation reattributed Li2020→Liu2025; 7 PMID-only footnotes given DOIs; Sodek 1988 collagen half-life (3d molar PDL) confirmed.

[2026-06-12] verify | telomere-attrition ↔ genomic-instability causal-direction adjudication

  • Scope: targeted re-check of caused-by:/causes: frontmatter on hallmarks/telomere-attrition.md; internal consistency check on hallmarks/genomic-instability.md.
  • Verdict: primary causal direction is TA → GI (not GI → TA). Uncapping of critically short telomeres → ATM activation → NHEJ-mediated end-to-end fusions → BFB cycles → chromosomal instability. Supported by Celli & de Lange 2005 (Nat Cell Biol; TRF2-null MEFs; PDF-verified on this page).
  • GI → TA assessment: no solid primary-source GI→TA mechanism at the hallmark level. Oxidative damage → telomere shortening is correctly attributed to ROS/mitochondrial biology (not the genomic-instability hallmark per se). DDR-deficiency-impaired telomere processing (WRN/BLM helicase-dependent G-quadruplex resolution) is a real molecular nuance but constitutes a “loss-of-repair” cause, not a clean “accumulated genomic instability causes telomere erosion” causal edge.
  • Corrections made:
    • hallmarks/telomere-attrition.md frontmatter: removed [[genomic-instability]] from caused-by: (was incorrect); added [[genomic-instability]] to causes: (the correct direction); cleared caused-by: [].
    • hallmarks/telomere-attrition.md body § Position in causal hierarchy: removed “bidirectional amplification” framing; replaced with accurate upstream-node description and GI-cause note with Celli & de Lange 2005 citation.
    • hallmarks/genomic-instability.md body § Position in causal hierarchy: corrected “Direct upstream nodes per caused-by: frontmatter: none” (was contradicting the frontmatter); replaced with accurate description of telomere-attrition as the upstream cause with the Celli & de Lange 2005 mechanism.
    • hallmarks/telomere-attrition.md frontmatter: verified-date updated to 2026-06-12; verified-scope extended with adjudication notes.
  • No PDF re-read required: Celli & de Lange 2005 already PDF-verified on the 2026-05-04 pass; the adjudication relied on the body text’s own mechanism descriptions + the already-verified study footnote.
  • Reciprocal consistency: genomic-instability.md caused-by: ["[[telomere-attrition]]"] (frontmatter) was already correct and was not changed.
  • Note: the sim edge-audit earlier today independently flagged this same mis-direction as “Live edge mis-direction flag for human adjudication” — this wiki pass resolves it.

[2026-06-12] verify | yoshida-2020-bronchial-epithelium-mutations

  • Page: studies/yoshida-2020-bronchial-epithelium-mutations.md
  • Source checked: doi:10.1038/s41586-020-1961-1; pmid:31996850; PMC7021511 (OA full text). Read via pmc.ncbi.nlm.nih.gov/articles/PMC7021511/. Supplementary Table 1 (Excel, patient smoking histories) not independently accessed — PMC-hosted xlsx returned 404; per-subject pack-year data confirmed present per the Methods statement. All main-text quantitative claims verified against the PMC full text.
  • Corrections made (5):
    1. “median coverage reported as 16×” → “average coverage 16× (minimum inclusion threshold 8×; >95% sensitivity at 15×)” — paper uses “average”, not “median”; inclusion threshold and sensitivity figure added from Methods.
    2. Indel CI note resolved: “inference from partial text; verify exact CI against full PDF” → “No separate 95% CIs are reported for the 101/51 subgroup estimates; the p-value (p=0.001) covers the overall smoking effect on indel burden.” Confirmed the paper gives only combined p-value, no per-subgroup CIs.
    3. Driver gene note updated: “genes not enumerated in abstract; verify full list against supplement” → confirmed 86-gene panel and named genes (NOTCH1, TP53, ARID2, FAT1, PTEN, CHEK2, ARID1A) from Methods.
    4. Near-normal cell definition added (Methods-verified threshold: <2 within-patient + 2 between-patient non-smoker SDs above age-estimated burden).
    5. Mechanistic interpretation of ex-smoker vs current-smoker gap substantially expanded: added explicit Discussion-text quote supporting irreversibility of per-cell mutation burden; added two-compartment model quote; added the ex-smoker lung-cancer retention sentence (which is the paper’s strongest evidence for irreversibility). Clarified the “dilution by near-normal cells” framing as the paper’s actual mechanism.
  • Added (simulator-target specifics):
    • “Absolute burden at specific ages” paragraph: paper does not state absolute SNV counts at specific age milestones; Figure 1B linear regression extrapolates to ~1,100 SNVs/cell at age 50 from slope alone; intercept not numerically reported; tagged gap/intercept-not-reported.
    • Per-pack-year dose-response section: confirmed the paper states “no significant correlation … with duration of cigarette smoking or the number of cigarettes smoked per day”; confirmed Suppl Table 1 has per-subject pack-year data (Methods ref) but study is underpowered (n=9 smokers); only categorical representation is defensible.
  • All primary quantitative claims confirmed correct: 22 SNVs/cell/year (95% CI 20–25; p=10⁻⁸); ex-smoker +2,330 (95% CI 1,180–3,480); current +5,300 (95% CI 3,660–6,930); 4× enrichment (95% CI 2.0–7.9×; p=3×10⁻⁶); telomere p=0.0009; driver 2.1-fold (95% CI 1.0–4.4; p=0.04); SBS-5 ex-smoker 1,140 (95% CI 590–1,700), current 2,200 (95% CI 1,590–2,810; p<10⁻¹⁶).
  • Verified state: flipped to verified: true, verified-date: 2026-06-12, verified-by: claude.
  • Downstream propagation needed (for main agent): exposures/smoking.md (reversibility section cites this study — mechanistic interpretation now substantially more precise; confirm the irreversible-accrual framing is reflected there); processes/somatic-mutation-accumulation.md (tissue-rate table and near-normal cell discussion may benefit from the intercept gap tag and the expanded mechanistic discussion).

[2026-06-12] ingest | gingival-recession + periodontitis backfill (crowding / black-triangles / Grade C)

  • context: ad-hoc follow-on to the dental cluster (above), prompted by a real presentation — 38F, front-teeth recession that is interproximal as well as buccal, braces history, light brushing, no caries, crowding (“large teeth for a small mouth”). The interproximal finding exposed 3 mechanisms the freshly-seeded [[gingival-recession]] page didn’t cover. ADD-only extension of two already-verified pages (no existing prose/footnotes/verified-block altered).
  • updated: phenotypes/gingival-recession.md (was verified 2026-06-12) — seeded→verified (claude); stays verified:true, verified-scope extended w/ backfill breakdown. Added:
    • Dental crowding / tooth-size–arch-length discrepancy (axis 2): labially-displaced crowded incisors → root prominence through thin labial plate → dehiscence → recession even w/ gentle brushing. Valerio 2021 CBCT (doi:10.5624/isd.20200260, n=32) + Cadenas de Llano-Pérula 2023 systematic review (doi:10.1093/ejo/cjad026). Verifier: “independently associated”→Pearson r=−0.40/−0.57 (proclination NOT significant); review count 16→48 studies (16 on proclination); added 4th predictor (thin facial gingival margin); proclination significant in 10/16.
    • Open gingival embrasures / “black triangles” (new section): post-orthodontic interdental-papilla loss that mimics interproximal recession but is anatomic, not attachment loss. Tarnow 1992 papilla-fill principle (≤5mm ~100% / 6mm ~56% / ≥7mm ≤27%) + prevalence (Burke 1994 41.9%; Ko-Kimura 2003 43.7%, 66.7% in >20yo, n=80 added). Differentiation table (black triangle vs RT2/3 periodontitis). Verifier: Tarnow 1992 + Burke 1994 closed-access, tagged gap/no-fulltext-access (figures consistent w/ secondary lit but not primary-verified).
    • Localized periodontitis — molar-incisor / Grade C (axis 1, brief): interproximal attachment loss at incisors in young adults, disproportionate to plaque → good hygiene doesn’t exclude it; disease detail deferred to [[periodontitis]].
    • classification-triage note at the RT1/2/3 table: interproximal involvement must be split into true attachment loss vs black triangles (management diverges).
  • updated: phenotypes/periodontitis.md (was verified 2026-06-12) — seeded→verified (claude); stays verified:true, scope extended. Added Grade A/B/C comparison table (Tonetti 2018, doi:10.1002/jper.18-0006) + C-MIP (Grade C molar-incisor pattern) subsection: young onset, rapid progression, plaque-disproportionate, familial, A. actinomycetemcomitans JP2 clone (530-bp leukotoxin-promoter deletion). Verifier: “~20-fold”→“10- to 20-fold” leukotoxin, anchored to Brogan 1994 primary source (doi:10.1128/iai.62.2.501-508.1994; the cited reviews Fine 2024 / Nibali 2026 don’t state the figure); Susin 2014 population-prevalence confirmed vs full PDF; Nibali 2026 closed-access gap/no-fulltext-access.
  • gaps surfaced: #gap/no-fulltext-access (Tarnow 1992, Burke 1994, Tonetti 2018, Nibali 2026 — closed-access); Haubek 2008 Lancet noted by verifier as the ultimate primary for the JP2-colonization-predicts-attachment-loss claim (a direct footnote there would strengthen it — deferred).
  • leak-gate: clean (3 checks). Both pages’ verified blocks + the gingival-recession targeted banner preserved.

[2026-06-12] verify | Farr 2024 D+Q bone RCT — schedule + design corrected across 4 pages (sim-calibration-driven)

  • context: dispatched wiki-verifier on Farr 2024 (doi:10.1038/s41591-024-03096-2) — the one abstract-only, schedule-contradictory dependency surfaced while calibrating the D+Q senolytic into the aging-simulator (model/dq-calibration-design.md). PDF read end-to-end (Methods p.11).
  • canonical schedule established: D 100 mg × 2 consecutive days + Q 1000 mg × 3 consecutive days (staggered), every 28 days × 5 cycles = 20 wk, open-label (not double-blind — paper states over-encapsulation for blinding was cost-prohibitive). Corrects two prior cross-page errors: “monthly × 6 cycles” (6 cycles contradicted the 20-wk duration) and the “double-blind” label.
  • primary endpoint confirmed: CTx Δ @20 wk p=0.611 (NS). Secondary P1NP +16% @2wk (p=0.020), +16% @4wk (p=0.024), −9% @20wk (NS). Exploratory high-T-cell-p16 tertile: P1NP +34%/CTx −11% @2wk, radius BMD +2.7% @20wk.
  • SASP measurement confirmed: 36 circulating SASP factors at baseline + 2 wk → no significant D+Q-vs-control change; no adipose biopsy; T-cell p16 mRNA baseline-only (stratifier). Trial confirms neither senescent-cell clearance nor a systemic SASP drop — dual-null.
  • updated (verifier): molecules/compounds/dasatinib.md, molecules/compounds/quercetin.md, interventions/pharmacological/senolytics.md — schedule + open-label + SASP facts + age (≥70→60–90); each verified-scope extended (Farr now PDF-read).
  • updated (main agent): phenotypes/osteoporosis.md — footnote schedule “monthly × 6 cycles”→“every 28 d × 5 cycles”, open-label note, verified-scope re-correction (the prior 2026-05-23 “end-to-end” pass had recorded “3 d × 6 cycles” in error — a verified-page-carried-verifier-error).
  • sim fallout (model/, separate commit): folded canonical schedule + dual-null into dq-calibration-design.md; corrected an upstream error in senescence-inflammation-loop-design.md §8 — the “Farr 2024 P1NP @2wk” λ_infl anchor was a category error (P1NP = bone-formation, not SASP) and Farr’s SASP panel was null; removed it, λ_infl range now rests on Hickson + acute-IL-6.
  • gaps surfaced: #gap/hickson-cells-vs-mrna-labeling (Hickson p16/p21 −35/−17% labeled ”% cells” on compound pages but “mRNA” on cellular-senescence.md — bears on whether the kill fraction is a true per-cell fraction); #gap/dq-cadence-farr-unverified cleared.
  • leak-gate: clean (3 checks).
