# Research stream coverage — 2026-09-26

WP-0003 T01 working matrix. Entries mark located evidence, not completed streams.

| Stream | Current evidence | Key gap / disagreement |
| --- | --- | --- |
| A — GUI architecture | No dedicated primary-source comparison yet | Presentation/domain separation and competing historical models |
| B — Navigation/hypermedia | [N01–N04/N06](NavigationRenderingEvidence.md): htmx, SvelteKit and browser history | Framework examples versus pinned application behavior; direct entry versus transient state |
| C — Rendering/execution | [N05](NavigationRenderingEvidence.md): SvelteKit HTML/client options; existing SRC-0001 interpretation | Pre-rendering, hydration, islands and streaming lack comparable implementation coverage |
| D — Authority/synchronization | [Transactional evidence](TransactionalEvidenceExpansion.md), [frontend recovery](FrontendRecoveryImplementations.md), [Matrix experiment](MatrixRecoveryExperiment.md) | Synthetic receiver cannot prove production durability/deduplication; canonical admission remains open |
| E — Composition/organization | Seed catalog only | Independent feature/deployment boundaries and their operational cost |
| F — Quality | Retention/recovery guidance; navigation resilience requirements | No accessibility/performance validation; no-script support is narrower than resilience |

Next slice is implementation evidence for B/C, not expansion of the candidate count.
VC-01/02 are synthetic reviewed drafts; VC-03 is provisional; VC-04–10 remain planned.
No source count is used as a recurrence score or evidence-gate substitute.
