|
// empty alt text with a vision-model-generated factual caption.

// dedupes across runs and across documents (shared logos / chart
|
|
// templates caption once, not once per document).
|
|
//
|
|
// Why this matters: an empty-alt image gets paraphrased away by
|
|
// text summarization. With a caption, the alt text carries enough
|
|
// semantic load that the generation LLM tends to preserve the
|
|
// image reference inline at the right paragraph.
|
|
//
|
|
// Scope: we only caption images whose absolute path lives under
|
|
// <project>/wiki/media/<source-slug>/ — i.e. images the current
|
|
// ingest produced. User-typed external URLs in markdown source
|
|
// documents are passed through untouched.
|
|
//
|
|
// Master-toggle behavior: when `multimodalConfig.enabled` is
|
|
// false, we don't just skip the caption LLM call — we ALSO
|
|
// strip `` references from sourceContent before the LLM
|
|
// sees it, AND skip the post-write safety-net injection further
|
|
// down. Net effect: the wiki-side pipeline never references
|
|
// images at all. Without the strip + skip, image references
|
|
// would leak via two paths:
|
|
// 1. The LLM-generation prompt sees them in sourceContent and
|
|
// can preserve them in the generated wiki pages
|
|
// 2. injectImagesIntoSourceSummary unconditionally appends a
|
|
// `## Embedded Images` section to wiki/sources/<slug>.md
|
|
// Both paths land image refs into wiki pages, which then get
|
|
// embedded → searchable → visible in the search image grid even
|
|
// though the user disabled captioning. This was the user-
|
|
// surprising behavior that prompted the fix.
|
|
//
|
|
// Rust extraction itself is untouched: images still land on disk
|
|
// under wiki/media/<slug>/ (cheap), and the raw-source preview
