SHARD-WP-0003 T3. Whole-file write-granularity anchor: an entire wiki (content + app engine) in one self-contained HTML file -> save rewrites the whole file, no per-page atomicity. Node .tid file-per-tiddler substrate is git-diffable/ fine-grained, so the same engine spans the granularity spectrum by substrate (cf. Logseq file/DB UC-62, backend-swap UC-43). Tiddler = flexible-field record (UC-34); filter expressions = native-query tier (UC-52). UC-78 (single-file container-format attach). Enriched UC-35/40/34/52/43. Marks T3 done.
