epiphany-editor-core — Decisions
Decision log for the headless editing seam (EditorSession). Older decisions
for this crate were recorded in session notes and the Pass-12 batch rows it
filed (P12-E4, P12-E5); this file starts with their ratification.
Pass 12 G-pass (2026-07-07): E4/E5 are ratified
Dispositions in spec/PASS12_RATIFICATION_LOG.md ("G-pass tranche").
E4 adopt-as-implemented (req:format:barrier-matching): target-free
operations (SetMetadata, DeclareTransaction) are matched by score-wide
barriers only; opaque Registered operations match fully conservatively.
E5 semantics ratified (req:format:unsafe-tombstone): crossing a barrier
immediately deactivates the extension's remaining barriers; the crossing MUST
be durably recorded at the next commit; a tombstoned required = true
extension leaves the bundle read-only for dependents. The manifest-side byte
encoding is deferred to the Binary Format companion (new open question there:
the manifest is frozen at major 0, so the record rides the blob layer or a
new chunk kind — next bundle-format tranche);
extensions_requiring_tombstone() remains the producer awaiting that
consumer.
