Time Machine

Lees een record zoals het die dag stond, zonder dat vandaag erin lekt.

Elke opslag schrijft een revisie. Time Machine neemt een record en twee dagen, zoekt de revisie die aan het eind van elke dag gold, en toont beide panelen met een verschiltabel per veld. Waar het geen antwoord kan geven, noemt het de reden en toont het helemaal geen waarden in plaats van stilletjes terug te vallen op het huidige concept.

  • 200 revisions loaded per read
  • 2 days compared side by side
  • 0 fallbacks to the current version

Hoe het werkt

Van leeg record tot iets waar je op kunt handelen, in de volgorde waarin je het doet.

  1. 1

    Pick the record

    Choose the record type, then the record by its title. Changing the type clears the selection rather than carrying it over.

  2. 2

    Pick two days

    Neither later than today. The earlier one becomes the earlier panel on its own.

  3. 3

    Read the difference table first

    Fields in stable catalog order, then work back up into the panels for the full context around what moved.

Het probleem dat dit oplost

Wat er misgaat als dit werk verspreid staat over spreadsheets, documenten en iemands geheugen.

Hindsight in the postmortem

You read the account as it is now and conclude the decision was obvious. It was not, and the record from that week proves it.

A replay that quietly shows the present

A fallback to the newest version is worse than no answer, because it looks like an answer.

An argument about when something started

Creation is decided by the lowest revision number in the window, never by the earliest timestamp, so a clock that ran backwards does not become evidence.

Kernpunten

Waarom dit belangrijk is

A refusal renders no values

Record missing, no history, not yet created, history truncated, or a draft it cannot read. Each says which, and none of them shows the current version instead.

Timezones do not move a revision

Conversion is always UTC, so a colleague in another country reads the same day you do.

Old revisions still render

A stored draft is read through a deliberately looser schema, so a revision saved under since-changed rules is still readable.

Eerlijke grenzen

Wat dit wel en niet belooft

  • This is recorded time, not valid time. A record edited on the eighteenth about something that changed on the first looks the same as one that changed on the eighteenth, unless effective dates were authored on it.

  • It is not a full decision replay. External source content, historical model behaviour and linked metric definitions are not pinned, and following a link opens that record as it stands today.
