Every edition, archived. Every change, named.

A reference that quietly rewrites itself is not a reference. Each edition is frozen as a dated JSON file the moment it ships, so the difference between any two of them is a fact you can compute rather than a claim you have to accept.

The archive

One immutable snapshot per edition. Diff any two to see every succession.
EditionVerifiedSnapshotWhat it holds
v2026.Q3 current 2026-q3.json First archived edition. 58 elements, 12 groups, 28 marked essential, 1,421 tools tracked across the dossiers, 281 of them found dead, renamed, acquired or sunsetting.

The delta report

From the second edition onward, each one ships with a delta: seats that changed holder and the evidence that moved them, tools added to the graveyard, price bands that drifted, elements that changed maturity phase, and the churn rate per group. There is no delta report yet, because there is only one archived edition. The first one arrives with v2026.Q4 — and it will be built from a real re-verification pass, not from a diff of two files that were never re-checked.

Until then, the changelog carries every individual succession as it happens, dated, with the reason attached. That is the same information arriving one item at a time instead of one quarter at a time.

What is verified, and what is not

The current edition's rankings, pricing and status were verified on 2026-09-13. Corrections made since then are dated individually in the changelog and carried into the dossiers, but the bulk of the table has not been re-checked since that date and this page will not pretend otherwise. A verification date that quietly advances with every deploy is the single easiest lie a reference like this can tell.

Common questions

What is an elems edition?

A dated snapshot of the whole table — all 58 elements, their holders, price bands and maturity phases — written to a JSON file that is never rewritten afterwards. The live site always shows the current edition; the archive is what lets you prove what it said last quarter.

What is a delta report?

The diff between two editions, published as a page: which seats changed holder and why, which tools entered the graveyard, how price bands moved, and which elements changed maturity phase. It is the number nobody else can compute, because computing it requires having been wrong in public and kept the receipt.

How often does the table change?

Editions are quarterly. Corrections are not — a shutdown, an acquisition or an integrity failure moves a seat the week we verify it, and the changelog records it immediately. Waiting for a quarter boundary to tell you a tool is dead would be a reference optimising for its own tidiness.

The snapshots are open data under the same licence as everything else on the table. Diff them, chart them, cite them.
