How the record works.
The rules this surface obeys, what is built, and every source.
What this surface is allowed to do
These are not style preferences. Breaking one damages the asset.
| Allowed, because it is a record | Forbidden, because it is a rating |
|---|---|
| "Issued 4 March: 2027. Issued 12 November: 2028. Source." | "Slipping" |
| A line that goes down | A red line that goes down |
| "Restated from 103.4 to 101.8 on 15 August" | "Downgraded", "cut", "missed" |
| "Three revisions in 2025" | "Frequently revised", "unreliable" |
| A tooltip showing both values and both dates | A tooltip showing "−1.6% worse" |
The rule that follows: the vertical axis already carries direction, so nothing else may. Colour identifies the target period. Shape distinguishes a forecast from a result. The good/warning/critical palette used elsewhere on the web is deliberately absent from every chart here.
What is in this build, and what is not
Honest scope, so nothing here is mistaken for finished.
| Piece | State | What remains |
|---|---|---|
| Forecast revisions | real data: 4 subjects, 16 targets, 34 sourced points | more publishers, more targets |
| Data revisions (ALFRED) | collector written, never run | prove against the live endpoint on the host |
| Schedule revisions | specified, not built | deliberately last; it is the one about named companies |
| Exchange rates | partial: 3228 dates, 34 currencies | run collect_fx.py for the full history |
| Gap register | 9 entries, machine-readable | close them, or record why they cannot be closed |
| The lens, matrix, digest | working | port into semi.js, add a nav slot |
What the record knows it is missing
A tracker that shows only what it has is telling you half of what it knows. The withheld half is the half that tells you how far to trust the rest.

A personal project, built in a private capacity from public sources only. Published by YINDOR, the one-person business of Jorg Jansen. Not affiliated with or endorsed by any employer. Not investment advice, and no view is stated on any company or security anywhere on this site. This build is a working prototype. The exchange-rate file covers 2014-01-02 to 2026-08-13 and was last collected 2026-08-14; the vintage file was last collected 2026-08-14. Both dates are read from the files themselves, so a footer that has gone stale says so rather than repeating what was true at the time it was written.
