synthesis: shard spectrum across nine systems; fold into SHARD-WP-0002 (T11 eleven spectra, new T16)

Browse Source 
Cross-dive synthesis (research/260614-shard-spectrum-synthesis/) reading
the two Nelson conceptual systems, four engines, and three modern tools
across each other: a shard family matrix and eleven capability spectra
(addressing, content identity, structure, history, native query,
translation, attachment mode, operational envelope, access grant, write
granularity, content types) — positions anchored at both ends by a real
system, federation ops degrading by position. Through-lines:
files-canonical/index-derived wins; fine-grained addressing is adoptable;
transclusion=clone=embed is one primitive; structure/history federate iff
in-text; attach mode is a per-binding choice; Notion proves the platform
can enforce no-silent-mutation.

Folded into SHARD-WP-0002: T11 reframed around the eleven spectra; T12
page model stretched four ways (prose + typed records + non-Markdown
assets + query-defined); T13 adds Notion supplement; T14 rewritten as the
three-mode attachment taxonomy (file-store / in-engine-host /
external-API); T15 adds lossy-with-fidelity-report; new T16 (addressing,
content identity, dimensional/query navigation). UC coverage UC-34-43 ->
UC-34-59. Workplan now 16 tasks. No new UCs (synthesis only).
