Coder↔reviewer design loop (9 rounds, reviewer verdict: exhaustive) produced 92 specs; implemented +123 tests (465 -> 588 passing). The new round-trip coverage exposed three genuine data-loss bugs in the Markdown<->ProseMirror converter, all now FIXED (round-trip is lossless for these): 1. pageBreak was lost on export (no converter case -> rendered to "" and the node vanished). Now emits <div data-type="pageBreak"></div>, which the schema parses back -> round-trips. 2. A block image between blocks left an empty <p> artifact after import-hoisting, producing a phantom blank-gap diff on every sync. markdownToProseMirror now strips content-less paragraphs after generateJSON — with a schema-validity guard that keeps the obligatory single empty paragraph in `content: "block+"` containers (tableCell/tableHeader/blockquote/column/callout/doc), so empty cells/quotes never become an invalid `content: []`. 3. The `code` mark combined with another mark was not byte-stable (emitted nested HTML that the schema's `code` `excludes:"_"` collapsed on import). The converter now emits code-only when `code` co-occurs, matching the editor. New coverage spans media/diagram/details/columns/math/mention attribute round-trips, converter emission branches, git error paths, and engine decision branches. A dedicated test pins the empty-container schema validity (the review catch on the bug-2 fix). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
