A directory can be named *.md too, and a vanished path cannot be probed,
so the suffix test alone stranded its notes in the index. Emit the note
delete and the prefix delete together; the two key sets are disjoint.
Optional OTLP export of request-level metrics (request and response-byte
counters keyed by route/status/conditional-GET, a duration histogram out
to 600s) plus server spans for slow or 5xx requests, nested under the
incoming W3C trace context. Off unless an OTLP endpoint or uptrace DSN is
configured; a config-less server is byte-for-byte unchanged.
Thin local front-end over ANW-26's merge engine (query::execute_merge):
walk the vault once (vault::scan, same as doctor), evaluate the --query
string, assemble the merged document, write it to stdout. No HTTP, no
watcher, no index. Byte-identical to the HTTP merge mode for the same
vault and query.
Accept: text/markdown on /query concatenates matched note bodies into one
markdown document, each fragment preceded by an HTML-comment source marker.
Adds __anw-order (frontmatter-key ordering, asc/desc, missing-key-last) and
__anw-kind (homogeneity guard, 400 on a mixed merge). Both evaluate over the
full matched set before __anw-limit truncates. Merge mode uses its own
body-cloning projection; the JSON path is unchanged (no body clone).
