Subject Log Lifecycle

Roadmap project documentation for the lifecycle family — a formal-model change giving every subject log the same four occurrence shapes, so that liveness, the tombstone, and the rule that nothing follows a retire are written once instead of hand-built by each adopter.

Every log needs to say the same four things about a subject: it began, it changed, it was affirmed unchanged, it ended. Today each log says them in its own words. Six logs carry their own create predicate, four define liveness for themselves, and the arm refusing a write to a subject that is no longer live is repeated fifteen times in demand alone. Each copy is a place the rule can differ from its neighbours without anything noticing.

Caution

Designed, not built, and not yet merged. This describes the model as it stands at commit 4b53f118 on the branch jmpicnic/domain-ontology-affirm-kind of Saldubatech/manufacturing-ontologies — an unmerged branch, not the model’s main line. No running service adopts it: the runtime’s adaptation is PDEV-1898, which has not started. The deployed occurrence design is Occurrence Pattern.

Documents

• Lifecycle Shapes — the four shapes, what each may carry, and the three laws that come with them.
• Affirm — the act that claims a value is unchanged, and why that is an act rather than a read.
• D13 Contract — the per-adopter table the runtime builds against: names, codes, atoms, effects, and the envelope.

Status

The cut is verified and unmerged. Its Tier A gate is green — every root satisfiable, with the predictions registered before the run — and its Tier B soak has not run. Merging onto the integration line is the operator’s own hand.

One question stays open: the spelling of the business affiliate’s retire kind, stated for veto in the contract table.

One is settled. This project’s account of how reference data ends its life contradicted a published domain page, and the operator ruled on 2026-09-09 that the subject-log shape is of record. Lifecycle Shapes states it, and the superseded page now says so on its face.
