Total Space Archive closure ledger
All eighteen archive programs are closed at their stated frozen-census or current-holdings boundaries. That means every included row is measured and dispositioned—not that space history has stopped or every possible fact is known.

published scope exclusions
Every resolved edge has canonical endpoints, a relationship type, and a citation or explicit evidence disposition. Name-only guesses are forbidden.
Unresolved targets, missing evidence, review queues, disputes, and scope exclusions remain measured records. A hold is not evidence that a person, mission, or object never existed.
Checksum-bound identity and relationship exports use compressed newline-delimited JSON. A manifest records counts, byte sizes, checksums, and decoding instructions.
The presentation rollout first gave every reader-meaningful identity a useful base card—or a declared parent-linked collection row—with an honest evidence state, classification, stable navigation, source and relationship dispositions, and explicit no-image treatment. Two bounded cohorts now improve 74,498 law, policy, culture, science, safety, orbital, launch, space-object, launch-system, organization, and infrastructure cards with record-specific narrative composed from existing canonical fields.
The first cohort exposes 4,559 readable public source links and 32,114 routed relationships on the detail records it owns. The second gives every one of its 67,227 summaries a source-native distinguishing identity or fact. Missing facts and images remain explicit holds; reviewed media and field-level citations continue in later source-bounded cohorts.

Corrections preserve the finding, prior identity, resolution, cited sources, affected records, and validation evidence. Release notes are public history, not a substitute for a formal correction record when an asserted fact or identity was wrong.

Finding: The prior vehicle-orfeus-spas-primary-photo record used NASA frame STS080-719-005 from STS-80. NASA identifies that mission's observatory as ORFEUS-SPAS II, while the first ORFEUS-SPAS record is connected only to STS-51.
Resolution: Registered NASA frame STS051-15-035 for the STS-51 ORFEUS-SPAS record, preserved and reassigned the prior STS-80 master and derivatives to a new ORFEUS-SPAS II asset, and replaced the six misassigned NAS files only after checksum-guarded preservation succeeded.
The public release log preserves 22 dated archive updates. Corrections can be submitted from the main methodology page.
