Fix round 3 (review of 7ff9728):
Round 2's gate 1 (supportsEvidenceKeyIn(evidenceCatalogEntriesFromAssets(assets)))
still routed through evidenceCatalogEntryFor, matching on id || label ||
publicPath -- gate 2's question, asked over fewer rows, not the resolver's
actual success condition (assetKey === key && managementStatus === "READY"
&& Boolean(publicPath)). Two Asset shapes made the two predicates disagree:
a READY asset with publicPath null/"", and a READY asset whose publicPath
happens to satisfy the legacy /media/${someOtherKey}.svg convention for a
key that isn't its own assetKey. Both passed gate 1 while the resolver
could not produce real pixels, reproducing the validateDocument-VALID /
createPreview-throws-raw-Error disagreement a second time.
Rebuilt gate 1 in validate-working-copy.ts and
adapters/mock/project-public-render-model.ts directly from a new domain
function, supportsEvidenceKeyFromReadyAssets, that mirrors the resolver's
exact condition -- never through evidenceCatalogEntryFor again. Gate 2
keeps reading the merged catalog. Made the mock resolver total (returns a
placeholder instead of throwing, matching instant-preview.tsx's resolver),
removing a comment that asserted an invariant the code did not hold.
Wrapped mock-studio-gateway.ts's idempotent() so any non-StudioGatewayError
that reaches its catch is normalized before crossing the port -- closing
the class generally, not just this instance.
Reverted instant-preview.tsx's own gate 1 to the merged catalog (unlike
the mock adapters, its resolver is provably total, so a loose gate there
only ever degrades to a placeholder) -- round 2's narrowing there was a
separate regression: a CASE referencing a document-catalog-backed key
outside the editor's currently-loaded Asset list blanked the entire
preview instead of degrading one figure.
Pinned both slip-through shapes failing on both mock paths with the
thrown/rejected error's type asserted (StudioGatewayError, never a raw
Error), pinned idempotent()'s new wrapping via a validate/preview race,
pinned EVIDENCE_NOT_FOUND as reachable through validateWorkingCopy
directly, and pinned Instant Preview's graceful degradation.
