Synapse v1.7.2 — "knowledge-graph fixes: file-slug links, hidden aggregates, node click-to-open"

Patch release: three real knowledge-graph defects found while validating a clean re-ingest of a localized (Italian) vault. No migration, no API change.

Fixed

  • The knowledge graph stayed near-empty on localized (non-English) vaults. The wikilink resolver indexed pages only by _slugify(title), but the generation prompt mandates bare-slug wikilinks ([[multi-cloud-orchestration]]) that match the filename a page is filed under — and on a localized vault the title is localized, so _slugify(title) never reproduced the linked slug. Measured on a clean 4-source Italian ingest: 2 of 114 links resolved (2 edges). The resolver now also indexes pages by their file_path slug; the same ingest yields 58 of 114 resolved (29 edges).
  • index / log / overview appeared in the knowledge graph as stray isolated dots. They are now excluded from the graph via GRAPH_HIDDEN_PAGE_TYPES (alongside the existing query exclusion).
  • Clicking a node in the knowledge graph did not open its wiki page. downNode disabled sigma's mouse captor to stop the stage panning during a drag, which also suppressed the upNode / clickNode events. Click-to-open now runs from the endDrag (!moved) seam; stage-pan is prevented via preventSigmaDefault in moveBody (the official sigma v3 pattern).

Upgrade

No Alembic migrations. The graph fix takes effect for new ingests; existing graphs are correct for next re-ingest. Pull new images.
