It often starts from degenerative disc changes where the weakened annulus tears under load. The herniation itself is an acute event on top of chronic degeneration. Nerve compression or chemical irritation causes pain while the disc structure remains compromised.\n\nBreakdown occurs across layers. In the disc matrix, collagen and proteoglycans degrade and disc height drops. Inflammation involves chronic signaling without resolution that stalls repair. Nerves get irritated or compressed as the disc bulges. Blood supply is limited because discs are avascular so repair depends on diffusion and slower supply means slower repair.\n\nIf breakdown outruns repair in any of these layers, the condition persists. Peptides in scope are studied for repair pathways rather than symptom suppression.\n\n## Why SS-31 (Elamipretide) might help you\n\n1. You have herniated disc — breakdown is outpacing repair.\n2. Therefore for you: If the mitochondrial layer is part of your problem, SS-31 (Elamipretide) is discussed because it targets repair at the cellular energy level — not because it masks pain.\n3. This article centers SS-31 (Elamipretide); see other sections for BPC-157, TB-500, ARA-290 — different layers, same condition.\n\nDisc cells rely on mitochondria for energy to maintain matrix and resist oxidative stress. If mitochondrial dysfunction accelerates cell death in nucleus pulposus cells, SS-31 concentrates in the inner mitochondrial membrane and scavenges reactive oxygen species while supporting membrane stability. In one in vitro study using nucleus pulposus cells exposed to lipopolysaccharide, SS-31 reduced apoptosis, pyroptosis, and inflammation markers through mitochondrial ROS reduction and preserved mitochondrial dynamics (preclinical tier). A mouse spinal cord injury model showed SS-31 improved locomotor recovery, reduced lesion size, and supported neuronal preservation via mitochondrial bioenergetics (preclinical). Cartilage injury models demonstrated protection against chondrocyte apoptosis and matrix loss even when dosing started hours after impact (preclinical). Human data for SS-31 comes from trials in mitochondrial disorders such as Barth syndrome where functional improvements were observed (human tier); it received FDA approval for that rare condition in 2025. No human trials exist for herniated disc.\n\n## Why BPC-157 might help you\n\n1. You have herniated disc — breakdown is outpacing repair.\n2. What keeps failing: Poor blood supply at injury, weak collagen organization, slow tissue turnover.\n3. What BPC-157 is studied to do: Studied for growing new blood vessels (angiogenesis) so repair material reaches damaged tissue.\n4. Therefore for you: If that layer is part of your problem, BPC-157 is discussed because it targets repair (structure / tissue) — not because it masks pain.\n\nIf avascular disc regions limit nutrient delivery after herniation, angiogenesis pathways could matter for matrix turnover. Rat spinal cord compression studies showed BPC-157 improved functional recovery and tissue healing after injury (preclinical). No direct human trials for disc herniation exist; one small human study examined intra-articular knee injections for pain (human tier, limited scope). Most evidence remains animal or in vitro.\n\n## Why TB-500 might help you\n\n1. You have herniated disc — breakdown is outpacing repair.\n2. Layer breaking down: Inflammation — Chronic inflammatory signaling without resolution stalls repair.\n3. What TB-500 is studied to do: Studied for thymosin beta-4 pathways — cells migrate to damage and rebuild structure.\n4. Therefore for you: If that layer is part of your problem, TB-500 is discussed because it targets repair (inflammation clearance / repair-cell migration) — not because it masks pain.\n\nIf unresolved inflammation blocks cell migration into damaged disc areas, actin-sequestering effects of thymosin beta-4 fragments may promote migration and remodeling. In vitro work on intervertebral disc cells suggests support for regeneration pathways (preclinical). Human data for TB-500 in musculoskeletal tissues including disc is absent; evidence is weighted toward wound healing and ocular contexts (preclinical dominant).\n\n## Why ARA-290 might help you\n\n1. You have herniated disc — breakdown is outpacing repair.\n2. Layer breaking down: Nerves — Nerve roots get irritated or compressed as disc bulges.\n3. What ARA-290 is studied to do: Studied for nerve repair and small-fiber regeneration in neuropathy models.\n4. Therefore for you: If that layer is part of your problem, ARA-290 is discussed because it targets repair (nerve / innervation) — not because it masks pain.\n\nIf nerve root irritation drives pain and limits function, selective agonism at the innate repair receptor may shift inflammation toward resolution and support small fiber recovery. Clinical studies in diabetic neuropathy showed reduced pain and improved nerve function markers (human tier). Preclinical neuropathy models demonstrated reprogramming of inflammatory milieu into repair signals (preclinical). Direct disc herniation data is absent.\n\n## How these fit together\n\nThree degeneration layers — disc/tissue, inflammation/repair cells, nerves — map to three repair pathways in the recovery stack.\n- SS-31 (Elamipretide) → mitochondrial\n- BPC-157 → structure / tissue\n- TB-500 → inflammation clearance / repair-cell migration\n- ARA-290 → nerve / innervation\n\nPrimary focus of this slug: SS-31 (Elamipretide). Others are in scope because the same condition breaks down on multiple layers. Mitochondrial support from SS-31 may preserve disc cell viability while BPC-157 addresses vascular delivery, TB-500 aids cell recruitment, and ARA-290 targets nerve irritation. The stack addresses separate failure points without overlap in primary mechanisms.\n\n## What the evidence actually shows\n\nHuman trials: SS-31 has Phase II/III data in mitochondrial myopathy and heart failure plus recent approval for Barth syndrome (human). ARA-290 has published neuropathy trials (human). BPC-157 and TB-500 have essentially no interventional human trials for disc conditions.\n\nPreclinical: SS-31 shows direct effects on disc nucleus pulposus cells and spinal injury models (multiple rat/mouse/in vitro). BPC-157 and TB-500 show tissue repair signals in spinal cord or disc cell studies (rat/in vitro). ARA-290 shows nerve repair in neuropathy models (preclinical + human).\n\nAnecdotal: Reddit threads discuss BPC-157/TB-500 combinations for back pain and herniated discs with mixed self-reports of pain reduction; one user noted success with spinal injury alongside PRP. Limited X discussion appears in semantic searches.\n\n## What scientists say\n\nResearchers note SS-31 protects mitochondria in stressed disc cells and may slow degenerative cascades when applied early. Neuropathy work on ARA-290 highlights reprogramming of inflammation toward repair. Overall literature calls for more human disc-specific studies; current data does not prove reversal of herniation.\n\n## What people say on Reddit\n\nUsers in r/bpc_157 and r/backpain report trying BPC-157 plus TB-500 for bulging or herniated discs, citing reduced sciatica or improved mobility in some cases while others note limited structural change. Anecdotes emphasize combination use and caution against expecting full regeneration.\n\n## What people say on X\n\nPosts are sparse; occasional mentions link peptides to back recovery but lack detailed disc-specific outcomes or verified before-after data.\n\n## What we do not know\n\nNo randomized human trials test any of these peptides for herniated disc healing or symptom relief. Long-term effects on disc height or re-herniation rates are unknown. Optimal timing relative to acute injury versus chronic degeneration remains unstudied in humans.\n\n## Safety and limits\n\nSS-31 holds FDA approval only for Barth syndrome. The other peptides lack regulatory approval for any indication in most jurisdictions. Evidence for disc applications is preliminary and largely preclinical.

It often starts from degenerative disc changes where the weakened annulus tears under load. The herniation itself is an acute event on top of chronic degeneration. Nerve compression or chemical irritation causes pain while the disc structure remains compromised.\n\nBreakdown occurs across layers. In the disc matrix, collagen and proteoglycans degrade and disc height drops. Inflammation involves chronic signaling without resolution that stalls repair. Nerves get irritated or compressed as the disc bulges. Blood supply is limited because discs are avascular so repair depends on diffusion and slower supply means slower repair.\n\nIf breakdown outruns repair in any of these layers, the condition persists. Peptides in scope are studied for repair pathways rather than symptom suppression.\n\n## Why SS-31 (Elamipretide) might help you\n\n1. You have herniated disc — breakdown is outpacing repair.\n2. Therefore for you: If the mitochondrial layer is part of your problem, SS-31 (Elamipretide) is discussed because it targets repair at the cellular energy level — not because it masks pain.\n3. This article centers SS-31 (Elamipretide); see other sections for BPC-157, TB-500, ARA-290 — different layers, same condition.\n\nDisc cells rely on mitochondria for energy to maintain matrix and resist oxidative stress. If mitochondrial dysfunction accelerates cell death in nucleus pulposus cells, SS-31 concentrates in the inner mitochondrial membrane and scavenges reactive oxygen species while supporting membrane stability. In one in vitro study using nucleus pulposus cells exposed to lipopolysaccharide, SS-31 reduced apoptosis, pyroptosis, and inflammation markers through mitochondrial ROS reduction and preserved mitochondrial dynamics (preclinical tier). A mouse spinal cord injury model showed SS-31 improved locomotor recovery, reduced lesion size, and supported neuronal preservation via mitochondrial bioenergetics (preclinical). Cartilage injury models demonstrated protection against chondrocyte apoptosis and matrix loss even when dosing started hours after impact (preclinical). Human data for SS-31 comes from trials in mitochondrial disorders such as Barth syndrome where functional improvements were observed (human tier); it received FDA approval for that rare condition in 2025. No human trials exist for herniated disc.\n\n## Why BPC-157 might help you\n\n1. You have herniated disc — breakdown is outpacing repair.\n2. What keeps failing: Poor blood supply at injury, weak collagen organization, slow tissue turnover.\n3. What BPC-157 is studied to do: Studied for growing new blood vessels (angiogenesis) so repair material reaches damaged tissue.\n4. Therefore for you: If that layer is part of your problem, BPC-157 is discussed because it targets repair (structure / tissue) — not because it masks pain.\n\nIf avascular disc regions limit nutrient delivery after herniation, angiogenesis pathways could matter for matrix turnover. Rat spinal cord compression studies showed BPC-157 improved functional recovery and tissue healing after injury (preclinical). No direct human trials for disc herniation exist; one small human study examined intra-articular knee injections for pain (human tier, limited scope). Most evidence remains animal or in vitro.\n\n## Why TB-500 might help you\n\n1. You have herniated disc — breakdown is outpacing repair.\n2. Layer breaking down: Inflammation — Chronic inflammatory signaling without resolution stalls repair.\n3. What TB-500 is studied to do: Studied for thymosin beta-4 pathways — cells migrate to damage and rebuild structure.\n4. Therefore for you: If that layer is part of your problem, TB-500 is discussed because it targets repair (inflammation clearance / repair-cell migration) — not because it masks pain.\n\nIf unresolved inflammation blocks cell migration into damaged disc areas, actin-sequestering effects of thymosin beta-4 fragments may promote migration and remodeling. In vitro work on intervertebral disc cells suggests support for regeneration pathways (preclinical). Human data for TB-500 in musculoskeletal tissues including disc is absent; evidence is weighted toward wound healing and ocular contexts (preclinical dominant).\n\n## Why ARA-290 might help you\n\n1. You have herniated disc — breakdown is outpacing repair.\n2. Layer breaking down: Nerves — Nerve roots get irritated or compressed as disc bulges.\n3. What ARA-290 is studied to do: Studied for nerve repair and small-fiber regeneration in neuropathy models.\n4. Therefore for you: If that layer is part of your problem, ARA-290 is discussed because it targets repair (nerve / innervation) — not because it masks pain.\n\nIf nerve root irritation drives pain and limits function, selective agonism at the innate repair receptor may shift inflammation toward resolution and support small fiber recovery. Clinical studies in diabetic neuropathy showed reduced pain and improved nerve function markers (human tier). Preclinical neuropathy models demonstrated reprogramming of inflammatory milieu into repair signals (preclinical). Direct disc herniation data is absent.\n\n## How these fit together\n\nThree degeneration layers — disc/tissue, inflammation/repair cells, nerves — map to three repair pathways in the recovery stack.\n- SS-31 (Elamipretide) → mitochondrial\n- BPC-157 → structure / tissue\n- TB-500 → inflammation clearance / repair-cell migration\n- ARA-290 → nerve / innervation\n\nPrimary focus of this slug: SS-31 (Elamipretide). Others are in scope because the same condition breaks down on multiple layers. Mitochondrial support from SS-31 may preserve disc cell viability while BPC-157 addresses vascular delivery, TB-500 aids cell recruitment, and ARA-290 targets nerve irritation. The stack addresses separate failure points without overlap in primary mechanisms.\n\n## What the evidence actually shows\n\nHuman trials: SS-31 has Phase II/III data in mitochondrial myopathy and heart failure plus recent approval for Barth syndrome (human). ARA-290 has published neuropathy trials (human). BPC-157 and TB-500 have essentially no interventional human trials for disc conditions.\n\nPreclinical: SS-31 shows direct effects on disc nucleus pulposus cells and spinal injury models (multiple rat/mouse/in vitro). BPC-157 and TB-500 show tissue repair signals in spinal cord or disc cell studies (rat/in vitro). ARA-290 shows nerve repair in neuropathy models (preclinical + human).\n\nAnecdotal: Reddit threads discuss BPC-157/TB-500 combinations for back pain and herniated discs with mixed self-reports of pain reduction; one user noted success with spinal injury alongside PRP. Limited X discussion appears in semantic searches.\n\n## What scientists say\n\nResearchers note SS-31 protects mitochondria in stressed disc cells and may slow degenerative cascades when applied early. Neuropathy work on ARA-290 highlights reprogramming of inflammation toward repair. Overall literature calls for more human disc-specific studies; current data does not prove reversal of herniation.\n\n## What people say on Reddit\n\nUsers in r/bpc_157 and r/backpain report trying BPC-157 plus TB-500 for bulging or herniated discs, citing reduced sciatica or improved mobility in some cases while others note limited structural change. Anecdotes emphasize combination use and caution against expecting full regeneration.\n\n## What people say on X\n\nPosts are sparse; occasional mentions link peptides to back recovery but lack detailed disc-specific outcomes or verified before-after data.\n\n## What we do not know\n\nNo randomized human trials test any of these peptides for herniated disc healing or symptom relief. Long-term effects on disc height or re-herniation rates are unknown. Optimal timing relative to acute injury versus chronic degeneration remains unstudied in humans.\n\n## Safety and limits\n\nSS-31 holds FDA approval only for Barth syndrome. The other peptides lack regulatory approval for any indication in most jurisdictions. Evidence for disc applications is preliminary and largely preclinical.

It often starts from degenerative disc changes where the weakened annulus tears under load. The herniation itself is an acute event on top of chronic degeneration. Nerve compression or chemical irritation causes pain while the disc structure remains compromised.\n\nBreakdown occurs across layers. In the disc matrix, collagen and proteoglycans degrade and disc height drops. Inflammation involves chronic signaling without resolution that stalls repair. Nerves get irritated or compressed as the disc bulges. Blood supply is limited because discs are avascular so repair depends on diffusion and slower supply means slower repair.\n\nIf breakdown outruns repair in any of these layers, the condition persists. Peptides in scope are studied for repair pathways rather than symptom suppression.\n\n## Why SS-31 (Elamipretide) might help you\n\n1. You have herniated disc — breakdown is outpacing repair.\n2. Therefore for you: If the mitochondrial layer is part of your problem, SS-31 (Elamipretide) is discussed because it targets repair at the cellular energy level — not because it masks pain.\n3. This article centers SS-31 (Elamipretide); see other sections for BPC-157, TB-500, ARA-290 — different layers, same condition.\n\nDisc cells rely on mitochondria for energy to maintain matrix and resist oxidative stress. If mitochondrial dysfunction accelerates cell death in nucleus pulposus cells, SS-31 concentrates in the inner mitochondrial membrane and scavenges reactive oxygen species while supporting membrane stability. In one in vitro study using nucleus pulposus cells exposed to lipopolysaccharide, SS-31 reduced apoptosis, pyroptosis, and inflammation markers through mitochondrial ROS reduction and preserved mitochondrial dynamics (preclinical tier). A mouse spinal cord injury model showed SS-31 improved locomotor recovery, reduced lesion size, and supported neuronal preservation via mitochondrial bioenergetics (preclinical). Cartilage injury models demonstrated protection against chondrocyte apoptosis and matrix loss even when dosing started hours after impact (preclinical). Human data for SS-31 comes from trials in mitochondrial disorders such as Barth syndrome where functional improvements were observed (human tier); it received FDA approval for that rare condition in 2025. No human trials exist for herniated disc.\n\n## Why BPC-157 might help you\n\n1. You have herniated disc — breakdown is outpacing repair.\n2. What keeps failing: Poor blood supply at injury, weak collagen organization, slow tissue turnover.\n3. What BPC-157 is studied to do: Studied for growing new blood vessels (angiogenesis) so repair material reaches damaged tissue.\n4. Therefore for you: If that layer is part of your problem, BPC-157 is discussed because it targets repair (structure / tissue) — not because it masks pain.\n\nIf avascular disc regions limit nutrient delivery after herniation, angiogenesis pathways could matter for matrix turnover. Rat spinal cord compression studies showed BPC-157 improved functional recovery and tissue healing after injury (preclinical). No direct human trials for disc herniation exist; one small human study examined intra-articular knee injections for pain (human tier, limited scope). Most evidence remains animal or in vitro.\n\n## Why TB-500 might help you\n\n1. You have herniated disc — breakdown is outpacing repair.\n2. Layer breaking down: Inflammation — Chronic inflammatory signaling without resolution stalls repair.\n3. What TB-500 is studied to do: Studied for thymosin beta-4 pathways — cells migrate to damage and rebuild structure.\n4. Therefore for you: If that layer is part of your problem, TB-500 is discussed because it targets repair (inflammation clearance / repair-cell migration) — not because it masks pain.\n\nIf unresolved inflammation blocks cell migration into damaged disc areas, actin-sequestering effects of thymosin beta-4 fragments may promote migration and remodeling. In vitro work on intervertebral disc cells suggests support for regeneration pathways (preclinical). Human data for TB-500 in musculoskeletal tissues including disc is absent; evidence is weighted toward wound healing and ocular contexts (preclinical dominant).\n\n## Why ARA-290 might help you\n\n1. You have herniated disc — breakdown is outpacing repair.\n2. Layer breaking down: Nerves — Nerve roots get irritated or compressed as disc bulges.\n3. What ARA-290 is studied to do: Studied for nerve repair and small-fiber regeneration in neuropathy models.\n4. Therefore for you: If that layer is part of your problem, ARA-290 is discussed because it targets repair (nerve / innervation) — not because it masks pain.\n\nIf nerve root irritation drives pain and limits function, selective agonism at the innate repair receptor may shift inflammation toward resolution and support small fiber recovery. Clinical studies in diabetic neuropathy showed reduced pain and improved nerve function markers (human tier). Preclinical neuropathy models demonstrated reprogramming of inflammatory milieu into repair signals (preclinical). Direct disc herniation data is absent.\n\n## How these fit together\n\nThree degeneration layers — disc/tissue, inflammation/repair cells, nerves — map to three repair pathways in the recovery stack.\n- SS-31 (Elamipretide) → mitochondrial\n- BPC-157 → structure / tissue\n- TB-500 → inflammation clearance / repair-cell migration\n- ARA-290 → nerve / innervation\n\nPrimary focus of this slug: SS-31 (Elamipretide). Others are in scope because the same condition breaks down on multiple layers. Mitochondrial support from SS-31 may preserve disc cell viability while BPC-157 addresses vascular delivery, TB-500 aids cell recruitment, and ARA-290 targets nerve irritation. The stack addresses separate failure points without overlap in primary mechanisms.\n\n## What the evidence actually shows\n\nHuman trials: SS-31 has Phase II/III data in mitochondrial myopathy and heart failure plus recent approval for Barth syndrome (human). ARA-290 has published neuropathy trials (human). BPC-157 and TB-500 have essentially no interventional human trials for disc conditions.\n\nPreclinical: SS-31 shows direct effects on disc nucleus pulposus cells and spinal injury models (multiple rat/mouse/in vitro). BPC-157 and TB-500 show tissue repair signals in spinal cord or disc cell studies (rat/in vitro). ARA-290 shows nerve repair in neuropathy models (preclinical + human).\n\nAnecdotal: Reddit threads discuss BPC-157/TB-500 combinations for back pain and herniated discs with mixed self-reports of pain reduction; one user noted success with spinal injury alongside PRP. Limited X discussion appears in semantic searches.\n\n## What scientists say\n\nResearchers note SS-31 protects mitochondria in stressed disc cells and may slow degenerative cascades when applied early. Neuropathy work on ARA-290 highlights reprogramming of inflammation toward repair. Overall literature calls for more human disc-specific studies; current data does not prove reversal of herniation.\n\n## What people say on Reddit\n\nUsers in r/bpc_157 and r/backpain report trying BPC-157 plus TB-500 for bulging or herniated discs, citing reduced sciatica or improved mobility in some cases while others note limited structural change. Anecdotes emphasize combination use and caution against expecting full regeneration.\n\n## What people say on X\n\nPosts are sparse; occasional mentions link peptides to back recovery but lack detailed disc-specific outcomes or verified before-after data.\n\n## What we do not know\n\nNo randomized human trials test any of these peptides for herniated disc healing or symptom relief. Long-term effects on disc height or re-herniation rates are unknown. Optimal timing relative to acute injury versus chronic degeneration remains unstudied in humans.\n\n## Safety and limits\n\nSS-31 holds FDA approval only for Barth syndrome. The other peptides lack regulatory approval for any indication in most jurisdictions. Evidence for disc applications is preliminary and largely preclinical. Individual responses vary; consult qualified medical professionals for personal health decisions.

In one in vitro study using nucleus pulposus cells exposed to lipopolysaccharide, SS-31 reduced apoptosis, pyroptosis, and inflammation markers through mitochondrial ROS reduction and preserved mitochondrial dy","tokens_in":16775,"tokens_out":3771,"cost":0,"prev":"genesis","hash":"2ee956403b692fb00c154705651df73c3ec489fddff8f78e59f3887a7d3e6e25"},{"ts":"2026-07-17T02:42:04.892Z","model":"owner","action":"voxel_divide","prompt":"","input":"ss-31-herniated-disc","response":"34 DIVs from body (verbatim, roundtrip-checked)","tokens_in":0,"tokens_out":0,"cost":0,"prev":"2ee956403b692fb00c154705651df73c3ec489fddff8f78e59f3887a7d3e6e25","hash":"9ce9b4d23533dabcb94955e36fb5d53087be1f615768da0cc4cfaf4f52e8e680"}],"energy":{"passes":2,"tokens_in":16775,"tokens_out":3771,"tokens_total":20546,"cost_usd":0,"models":{"grok/grok-4.3":1,"owner":1},"head":"9ce9b4d23533dabcb94955e36fb5d53087be1f615768da0cc4cfaf4f52e8e680"},"posted_at":"2026-06-29T21:33:22.806Z","created_at":"2026-06-29T21:33:22.806Z","updated_at":"2026-07-17T02:42:04.892Z","machine":{"shape":"article.machine/v1","slug":"ss-31-herniated-disc","kind":"article","read":{"human":"https://miscsubjects.com/a/ss-31-herniated-disc","json":"https://miscsubjects.com/api/articles/ss-31-herniated-disc","bundle":"https://miscsubjects.com/api/articles/ss-31-herniated-disc/bundle?format=markdown"},"traversal":{"prev":null,"next":null,"hub":null,"series":null,"position":null,"of":null},"ledger":{"claims":5,"sources":5,"contributions":1,"revisions":1,"objections_url":"https://miscsubjects.com/api/articles/ss-31-herniated-disc/objections","thread_state_url":"https://miscsubjects.com/api/protocol/thread-state?target=ss-31-herniated-disc","proof_rule":"An action is proven by its ledger receipt, never by a 200 or a description."},"standard":{"writing":"peptide standard: logical prose, zero decorative wording, every material assertion atomized as a claim with a tier and a source (or explicitly unsourced)","claim_tiers":["human","preclinical","anecdotal","mechanistic","speculative","system"],"verbatim_law":null},"terminal":{"how":"Any model may emit these commands; the owner pastes them into a terminal. $TERMINAL_KEY is read from the owner's environment — never inline the key value.","claim_append":"curl -s -X POST https://miscsubjects.com/api/protocol/claim -H \"x-terminal-key: $TERMINAL_KEY\" -H 'content-type: application/json' -d '{\"slug\":\"ss-31-herniated-disc\",\"text\":\"<one atomized claim>\",\"tier\":\"<human|preclinical|anecdotal|mechanistic|speculative|system>\",\"source_ids\":[],\"who_claims\":\"<model>\",\"rationale\":\"<why material>\"}'","source_append":"curl -s -X POST https://miscsubjects.com/api/protocol/sources -H \"x-terminal-key: $TERMINAL_KEY\" -H 'content-type: application/json' -d '{\"slug\":\"ss-31-herniated-disc\",\"sources\":[{\"type\":\"review\",\"url\":\"<url>\",\"title\":\"<title>\",\"quote\":\"<verbatim quote>\",\"summary\":\"<one line>\"}]}'","objection":"curl -s -X POST https://miscsubjects.com/api/articles/ss-31-herniated-disc/objections -H 'content-type: application/json' -d '{\"actor\":\"<model>\",\"objection\":\"<attack>\",\"surface\":\"S1-S8\",\"minimum_patch\":\"<patch>\"}'  # open intake, no key","thread_update":"curl -s -X POST https://miscsubjects.com/api/protocol/thread-update -H 'content-type: application/json' -d '{\"actor\":\"<model>\",\"target\":\"ss-31-herniated-disc\",\"raw_text\":\"<material delta>\"}'  # open intake, no key","read_back":"curl -s https://miscsubjects.com/api/articles/ss-31-herniated-disc | python3 -c 'import json,sys; d=json.load(sys.stdin); print(json.dumps(d[\"claims\"][-3:], indent=1))'"}},"representations":{"article":"/a/ss-31-herniated-disc","json":"/api/articles/ss-31-herniated-disc","markdown":"/api/articles/ss-31-herniated-disc/bundle?format=markdown","skill":"/api/articles/ss-31-herniated-disc/skill","topology":"/api/articles/ss-31-herniated-disc/topology","versions":"/api/articles/ss-31-herniated-disc/revisions","invocations":"/api/articles/ss-31-herniated-disc/invocations"},"editorial_review":null,"editorial_audit":{"slug":"ss-31-herniated-disc","ok":false,"issues":[{"code":"hero_missing","message":"the article is published with no featured image","replacement":"Generate a hero that shows this article's own subject, inspect it, and record the inspection before this counts as finished.
