One commit for the work accumulated in the working tree since Step 6.3, which had never been split into per-step commits: - src/local-surfaces.js + src/surface-url.js (new); src/ui.js, src/validation.js, src/connection.js and public/index.html updated for local-surface hosting and generic surface rendering - tests: local-surfaces (20), scifi-surfaces (24) and postmessage-interop (7) new; connection/museum-gallery/surface-validation suites updated - reference exhibits: shared/contract-core.js defaults to Contract 5.3 (major 5, minor 3, xzbt 5.3); museum-gallery advertises its surface catalog; aquarium/haunted-house/planetarium adapters updated - SciFi-XZBT (Step 6.7A/6.7B): surface-mode.js + surface-bus.js, Observation-surface boot branch, local-change hooks, view.pillars / view.warp-flight targets; fixture byte-identical to G:/.vibe/SciFi-XZBT - SciFi-XZBT contract adapter handshake fix: the inbound bridge filter no longer gates on an exact advisory xzbt value (Contract 5.3 §6.5), only on its presence/type, matching the host's own envelope validation; the adapter now advertises contract minor 3 / version 5.3.0, which it already implemented via the 5.3 surfaces field. Root cause of the five failing postmessage-interop tests (host hello was silently dropped). - docs: architecture 6.4 and 6.7A, reference 6.6 and 6.7; evidence logs; test-fixtures/PROVENANCE.md resync record Test results: NGN 154/154 (was 149/154); postmessage-interop 7/7 (was 2/7); SciFi contract harness 21/21, real-adapter suite 32/32. git diff --check clean for changed files; two pre-existing trailing-whitespace lines remain in test-fixtures/reference-exhibits/scifi/index.html, copied verbatim from the authoritative SciFi source. Step 6.7 live verification (browser Observation, packaged standalone) is still pending and is not claimed here.
