Extend the cross-dive synthesis from nine systems to the full fourteen (added Joplin, Logseq, the CRDT cohort Anytype/AFFiNE/AppFlowy, Trilium). Spectra grown 11 -> 13: new merge-model (none/git/conflict-notes/ native-CRDT) and content-opacity (plaintext/whole-shard-E2EE/per-item), plus identity-vs-placement emphasis (Trilium note/branch DAG), Logseq's in-file id:: addressing sweet spot, build-your-own derived query index, and a six-mode attachment taxonomy (file-store native/interchange-mirror, in-engine-host, local-REST, external-API, CRDT-replica, P2P). New through-lines: CRDT changes the merge math; identity != placement; metadata can be computed; attach surface != native store (+ substrate migration). UC fold-in extended UC-44-59 -> UC-44-67. Folded into SHARD-WP-0002: T11 thirteen spectra; T12 computed metadata + multi-placement/DAG identity; T13 CRDT-log supplement; T14 full six-mode attachment taxonomy; T15 HTML source model; T16 identity!=placement + derived index. Context inputs += four dives; acceptance UC-26-67. No new tasks, no new UCs (synthesis only). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
