THE METHOD

Proof-Driven Delivery

Proof-Driven Delivery is a way of shipping software where no claim outranks its evidence: every deliverable is attached to an artifact, every artifact is graded by how independently it can be verified, and readiness is a verdict a gate computes — never a feeling a person reports.

EVIDENCE GRADING

The three tiers

Not all evidence is equal, and pretending otherwise is how portfolios lie. Every claim here is graded T1, T2, or T3 — and the grade is displayed, including when it is the weakest one.

T1LIVE REPO / CI REPORT / DEPLOYED DEMO

Evidence that runs somewhere you can reach without me: a live repository, a CI report, a deployed demo. T1 survives my laptop being off.

WHAT QUALIFIES

  • A public repo you can clone and run
  • A CI workflow with green (or honestly red) runs attached to real commits
  • A production deploy you can click through yourself

ON THIS SITE

Case studies badged LIVE, and ledger rows whose artifact is a repo, workflow file, or public deploy.

T2LOCAL PROOF / TERMINAL OUTPUT / DIAGRAM / RUNBOOK

Evidence that exists as an artifact on disk — terminal output, a generated report, flow files, a runbook — but was produced locally. Real, inspectable, not yet independently re-runnable.

WHAT QUALIFIES

  • A machine-generated report (never hand-edited) checked into a repo
  • Terminal gate output or a coverage summary from a recorded run
  • Generated files on disk — test flows, ledgers, diagrams — that back a claim

ON THIS SITE

Case studies badged LOCAL PROOF, and ledger rows whose artifact is a report, script output, or on-disk directory.

T3WRITTEN EXPLANATION / PLANNED WORK

A written explanation or planned work. No artifact yet — the claim exists only as prose. T3 is allowed on this site under one condition: it is labeled T3.

WHAT QUALIFIES

  • A recorded result whose artifact must be regenerated before it can be quoted
  • A design, plan, or runbook for work that has not run yet
  • Anything where the honest answer to "show me" is a document, not an output

ON THIS SITE

Ledger rows marked T3 — like a device-cert number that honestly reads 0/256 until re-run — and every "improve next" note on the case studies.

THE CONTRACT

The rules

  1. 01Every claim carries its artifact.
  2. 02Unverified work is labeled, not hidden.
  3. 03Gates generate verdicts — 'ready' is a file, not a feeling.
  4. 04The system verifies itself in CI.
  5. 05Corrections are published, not papered over.
