Ki·dur
Most of what you build digitally disappears. Kidur holds what mattered — the arc of what you were becoming — on infrastructure you own, structured to be handed on.
Sumerian ki (place · base · earth) + dur (bond · tie · enclosure) — the foundational binding structure · a holon of the EvoBioSys thesis
Most of what we build digitally disappears.
Apps shut down. Drives fail. Formats rot. Cloud accounts lapse. The record of what mattered to you — what you were actually trying to do — gets lost with it. And at the scale of a mission, a second erosion sets in: once capital enters a regenerative venture, its vision drifts, until greenwashing and extraction arrive dressed as regeneration.
Two erosions, one root: no substrate holds the intention over time. Kidur tends both — a personal archive that keeps a life legible, and a mission-lock that keeps a portfolio honest.
A name older than writing.
Jakob, naming it (Dec 2025): "Kidur, K-I-D-U-R, is Sumerian for the foundation." Two roots, decoded — tap each panel.
An archive organised by when and what-it-was-part-of.
Not by app, not by format. A personal, sovereign record for a person's quests — projects, notes, recordings, memory — resting on four load-bearing commitments.
01Chronological index
Organised by when and by the quest it belonged to — the way a life actually unfolds, not the way a file system stores it.
02Privacy by design
It lives on your infrastructure… nothing reaches servers you haven't chosen. Privacy as architecture — a design intent, not a policy promise.
03Developmental trajectory
It tracks the arc: what you were becoming, the quests you carried — the shape of a life, not just its artifacts.
04Built to endure
Designed to be handed on — to family, collaborators, or institutions that carry forward what you couldn't finish. Legacy quests preserve the missions of those who died before fulfilling them.
One life. Thirty years of quests. One index.
This is the shape of the thing: a chronological spine where every quest becomes a node, and every node opens onto its own append-only record. One quest here was inherited — carried forward from a grandparent who never finished it.
Select a quest on the timeline. Its record reads back as lines from quest.jsonl — the append-only log Kidur keeps for everything you carry.

Illustrative data — a fictional life, no real person. The real archive indexes one person's full digital history, deduplicated and made navigable, from ordinary formats. Status vocabulary — fulfilled · dormant · active · carried-forward · handed-on — mirrors how a quest actually lives and passes on.
The same structure that holds a life can keep a portfolio honest.
At the EvoBioSys level, Kidur plays a second role: the keel that keeps the whole thesis from drifting off its north star once money and momentum arrive.
Mutual Holarchic Sovereignty
The relational rule: back what increases a holon's sovereignty; refuse what manufactures dependency. How the parts are allowed to relate.
The target equilibrium
Nine power poles sovereignly provide the nine Essential Physical Requirements. The state the whole system relates toward.
Fibrosis, or the guarded keel
Like scar tissue stiffening a living body, an un-guarded system calcifies — drifts from the equilibrium and hardens there. Kidur holds the tether.
Guarded: the venture holds at the equilibrium. Tap the button to watch it drift when nothing guards it.
A direction, honestly staked — not a shipped product.
The architecture points one way: local-first, graph-shaped, built on an append-only log that can never quietly rewrite your past. These are design commitments in development, not finished infrastructure.
The Loro CRDT (conflict-free replicated data type) layer earns its place because its native MovableTree solves structural reparenting — moving a note between quests without conflict. Beneath it, an append-only event log (kidur.jsonl) forms the spine: history accretes, nothing is silently overwritten. Federation — syncing between people's archives — stays deliberately deferred until Complete Memory completes.
Kin projects — the local-first commons Kidur grows within
Kidur's differentia: not another notes app, but a chronological quest-arc, a legacy handover, and a mission-lock — a life indexed to endure and be passed on.
A landing page live. A first archive being built. Grants as the path.
Honest status: prototype. The first version grows for one person's use — one full digital history, deduplicated, indexed, made navigable. When that works, it becomes something others can use.
Already real
- kidur.org is live — rebuilt 2026-06-20 as a waitlist landing page: EU-hosted, no tracking, double opt-in.
- First crates in development — kidur-core / kidur-log / kidur-supertag, early, inside the questhub.eco server.
- Personal-use build underway — one person's digital history as the proving ground.
Next on the line
- Single-user MVP — one full digital history, deduplicated, indexed, navigable end to end.
- Grant applications — NGI Zero Commons Fund, then Sovereign Tech Fund Germany.
- Then others — once it holds one life well, open it to the next.
kidur.org waitlist live; first crates in development.
One full digital history, deduplicated and navigable.
Grant-funded hardening; federation after Complete Memory.
The funding path — infrastructure, not a bet
- NGI Zero Commons Fund€5–50k
- Sovereign Tech Fund (DE)€50k–1M
- Sovereign Tech Fellowship
- Prototype Fund
- Horizon Europe CL4-2026-04
- then — the studio
The most fundable-by-grant piece in the whole thesis: fund it early as public infrastructure, not as a venture bet — non-dilutive grants first. These name the path; none is applied-for or won.
Substrate first. Then the layers that outlast you.
Kidur sits in a lineage: what a life remembers, what holds it, and what writes on top of it. Complete Memory gathers the record; Kidur becomes the durable substrate; SilkNotes is the authoring layer people work in.
Complete Memory
Ingests a life's digital history — the raw record to be deduplicated and indexed.
Kidur
The technical foundation: local-first, graph-shaped, built to endure and hand on.

Part of EvoBioSys — sovereign infrastructure, tools that belong to the people who use them, designed to evolve over decades rather than extract value over quarters. And a quieter promise: legacy quests, preserving the missions of people who died without fulfilling them — so a life's intention can be carried forward by family, collaborators, or the institutions that inherit it.
A place, and a binding — structured to outlast you.
Fund it early. Ally on sovereignty. Archive first.
Three kinds of people move this forward — and each door stands open.
Grant partners
Public-infrastructure funders who back sovereign tools before they're a bet — NGI Zero, Sovereign Tech Fund, and kin.
Sovereign-infra allies
Builders in the local-first commons — Solid, Anytype, Holochain, Ink & Switch neighbours — to weave with, not compete against.
First archivists
People with a life's worth of scattered digital history who want to be among the first to make it durable and navigable.
