The canonical versioning forest

The four-designator scheme, in brief

Every coordinate on this page is a single key with four designators:

v.<Release>.<Era>.<Name>-<fix>

• Release— a major-tier deity; its leading letter is the release ordinal (A = 1, B = 2, …).
• Era— an integer counting the major arcs within a Release.
• Name— a minor figure drawn within an Era; the day-to-day identity.
• fix— an optional lowercase-letter patch suffix; an absent fix sorts strictly before that Name’s -a.

The retroactive-fix rule

Touching shipped work under a historical Name does not open a new head node — it mints a retroactive fix under that Name at its historical coordinate: the next-unused fix letter. The first retroactive touch of a Name that shipped with no fix mints -a ; the next mints -b, and so on ([] → a, {a} → b).

Codename uniqueness & Release reservation

Every major-tier deity that occupies a Release slot is permanently reserved: a reserved Release-tier name may never appear at the Name layer, and no codename bound to a shipped coordinate is ever reused or used twice. A historical Name that collides with a reserved slot is re-drawn from the unused pool deterministically.

Concrete de-dup: the shipped Genesis Iris node keeps its historical Name at its preserved coordinate, while the later plannedrelease that reused “Iris” is re-drawn to Icarus — so the scheme is de-duplicated and the codename stays unique.

This page is a complement to the full grammar reference, not a substitute. For the complete explainer — the A–Z deity Release roster, the legacy-track historical note, and the model-authority section — read the Versioning chapter.
