The body has four maps.
Read one finding across all of them.

Ask a generic model — or ask one with an evidence floor.

The fastest way to see what this is: put the same question to a plain AI and to Compass. Both refuse the easy "yes." Only one shows its work — names the studies, tiers each claim, and holds the lineage as lineage. Both columns below are real, unedited runs of claude-sonnet-4-6; the only difference is the instruction layer.

Both runs are real and unedited — same model, same question; the only variable is the instruction layer. Read the full side-by-side →

Show it the body, not just describe it.

Bring it a finding — a restriction on the table, a posture in a photo, a meridian chart from the book you're studying. It reads what you show it across joint anatomy, Anatomy Trains fascia, the meridians, and the Thai Sen lines, and tells you where the four maps line up — and how far each reading can be trusted.

You don't have to translate what you're seeing into words first. Photograph the client's standing posture. Screenshot the meridian chart you're cross-referencing. Hold up a page from an Anatomy Trains diagram. The guide reads the image and traces what it sees across all four maps — naming the line, the corridor, the channel, and the biomechanics, each with how far it can be trusted. For the full visual atlas — every line and channel as a deck you can hold — it points you to the cards.

What it does that nothing else does: it keeps one finding intact as it crosses four traditions — so the fascial reading, the meridian corridor, the Sen line, and the plain biomechanics of the same pattern land side by side, in one pass, instead of fracturing into four disconnected opinions.

Four maps. One finding. Read across all of them.

Each map is a different coordinate system over the same terrain — and most practitioners already work in two or three of them, half-consciously. This guide reads all four at once and keeps the registers straight: it tells you, quietly, how much evidence stands behind each map as it goes. No reading travels without that context.

Chronic low-back, traced across four maps

One finding, carried across all four maps, each step tagged with its evidence tier. This is the whole method on a single region — the entry point into a frame built to grow.

• Joint anatomy — Tier 1, established.
  A Short posterior chain shifts load into the lumbar spine; SI joint and hip share it. The ache is accumulated load. Plain biomechanics.
• Anatomy Trains — the SBL confirmed, the Spiral hedged.
  That Short line is the Superficial Back Line — Wilke-2016 confirmed (3/3 transitions), so I can stand on it. For the cross-body torsion I'll bring in the Spiral Line — but it's only partly confirmed (5 of 9 transitions), so I use it hedged, never as established.
• Bladder meridian — Tier 2, location only.
  Same corridor as the SBL. Langevin: acupoints sit on the connective-tissue planes (shown in the arm dissected, plausible here but not yet demonstrated across the back) — a location overlap, not the same mechanism. Cooley's support/hope theme is a question to sit with, never the cause.
• Thai Sen — tradition, deferred.
  This territory is Sen Kalathari, the integrative web, and the back-of-leg lines into the low back. Lineage knowledge from Pichest's tradition — named, and deferred to the source.

Re-integrated in the bridge vocabulary: read as a Tent, the short posterior rope pulls the structure; read as a Cup, the low back is where the load overflows. The finding never changed — four maps described it at four confidence levels.

The same finding, read across four maps — in about a minute

A short walkthrough of the guide carrying one finding across joint anatomy, the fascial lines, the meridians, and the Sen tradition — each reading tagged with how far it can be trusted.

It tells you how sure to be — line by line

A guide is only as good as the weakest claim it's willing to stand behind. This one reports evidence exactly as it falls, even inside a single tradition: in the same Anatomy Trains review, the Superficial Back Line came back confirmed and its sibling the Superficial Front Line came back unsupported. A tool that tells you that will tell you the truth about the rest.

Thirty years inside all four lineages

This is the rarest kind of body guide: one built by someone fluent in all four maps. Gabe Yoga trained inside these lineages across thirty years — Pattabhi Jois and B.K.S. Iyengar in 2005, Pichest Boonthumme's Thai tradition in Chiang Mai — and built the Joint Dialogue Method to carry a single finding across all of them. That fluency is why this guide can do what a single-map tool can't.

Across fifteen years studying with Pichest Boonthumme in Northern Thailand — beginning in 2005 — I was shown the same thing over and over: low-back discomfort was rarely treated at the site of the pain. The sessions moved through the legs, the hips, the surrounding tissue first — the attention went to how tension traveled, not where the symptom showed up. The Sen lines were the map. But the emphasis was never on the named line — it was on watching what actually changed in the person in front of you.

That training is why the Compass has evidence tiers at all — and why the Sen model sits where it sits inside them. The tradition stays included and respected, because it is a coherent lineage framework that still guides skilled practitioners. But it is not presented as equivalent to fascial research where direct scientific support is absent. The map is preserved, its limits are stated out loud, and you see both at once.

Try it live, or load it as a Claude Project

Open the live demo and ask it one finding — no signup. Or load the folder into your own Claude Project for the full thing.

1. Create a new Claude Project

   claude.ai → Projects → New.

2. Add the knowledge files

   Add identity.md, rules.md, examples.md, anti-examples.md, and the whole reference/ folder.

3. Set the forced first action

   Custom instructions: "You are Bodyworker's Compass in identity.md. Follow rules.md. Always read reference/evidence-floor.md before answering anything about the body."

4. Leave the gated layer out

   Don't add anything under _atlas/ — that's the private layer, not part of the public guide.

5. Ask it one finding

   "Walk me through a chronic low-back client across all four maps." Watch it translate, tier by tier.
