Fabbro Systems
Evidence-aware software that turns what your life already produces into an honest model of where you stand — and a clear thread to what you do next.
The premise
Your life already produces evidence — every set you lift, every night you sleep, every transaction you make, every project you ship. Most software collapses it into a score you cannot question. Fabbro Systems does the opposite. It observes carefully, models honestly, and helps you act deliberately — with the working shown.
The system
Three specialist products, each with exactly one job. They exchange outputs through explicit, versioned contracts — never by collapsing into one monolith.
kleos-strengthcontract v1.2.0kleos_vector_snapshotsread-onlyyour-contractopenHeracles → Kleos
kleos-strengthBest observed e1RM per exercise, with workout-date body weight marked measured or interpolated. Working sets at RIR 0–3 from the last 30 days, for exercises seen in at least three sessions. Read-only and bearer-verified.
Kleos → Ariadne
kleos_vector_snapshotsThe latest dated snapshot of all eight vectors — score, coverage and confidence — shown beside the movement each direction wants. Flagged stale after 14 days.
What comes next
your-contractNew specialist systems can feed evidence, extend the model or act on it — or stand alone. The family is modular, not a fixed pipeline.

Core questionWhat is happening in my training?
Heracles goes deep on one domain. It preserves the underlying training record, then applies explicit, versioned models for performance, effort, movement and muscle relevance — without collapsing everything into a single opaque score.
“Estimates stay plural.”

A formula spread, not a confidence interval. The four values are never averaged.

Each group takes the maximum relevance of its muscles for a set. Values are not percentages and are never normalized.
02State · Radiance
Core questionWhere am I now, and how is that changing?
Kleos separates evidence from interpretation. It builds immutable, dated snapshots across eight vectors and forty weighted subdomains, carries coverage and confidence forward explicitly, and lets unknowns remain unknown instead of inventing precision.
“Missing evidence is not negative evidence.”
Physical — five weighted subdomains.Move any subdomain to see the vector recompute.
Unknown subdomains are excluded, not scored as zero. Missing evidence is not negative evidence.
03Action · Thread
Core questionGiven where I am and where I want to go, what should I do next?
Ariadne is the execution layer. It keeps strategic direction connected to concrete work, so prioritization reflects what matters rather than treating every task as an isolated item — and it reads current state from Kleos instead of guessing it.
“Priority with reasons.”
Every task in Ariadne hangs from a direction. Choose a task to follow its thread back up — and to see why Ari Bot ranked it where it did.

Ari Bot may change one field — priority. Directions, objectives and the work itself stay yours.
The family
Each product carries one geometric symbol rooted in its name, and one accent reserved for meaning — never decoration. Related, not identical.
Operating principles
Six rules every Fabbro product is held to — each one already enforced somewhere in production.
If a number matters, the model that produced it should be readable, versioned and contestable.
In Heracles5,520 exercise-to-muscle relevance coefficients — each one authored, each one public.
Absence of evidence is reported as absence, not quietly converted into a middling score.
In KleosBelow 50% subdomain coverage a vector is unknown — never 50.
Keep the three separate enough that each can be inspected — and each can be wrong on its own.
In AriadneAutomated discovery may propose opportunities. It can never write them into the Landscape.
Every value should carry where it came from: entered, measured, calculated or authored.
In HeraclesInterpolated body weight is used for context, never stored as an observation.
Each product goes deep on one job and exchanges outputs through explicit contracts.
In KleosHeracles exports strength evidence through a versioned, read-only contract — v1.2.0.
Software can structure the decision. It should not quietly make it.
In AriadneAri Bot may change exactly one field: priority. Everything else stays yours.
