The placeholder-restore pass in mdToHtml put code, math, mermaid and
allowed-HTML blocks back with a string replacement, so String.replace read
`$&`, `` $` ``, `$'` and `$$` in the *replacement* as substitution patterns.
A fenced block containing them rendered corrupted: `$&` re-inserted the
placeholder (`perl -pe 's/world/$& again/'` became
`s/world/___CODE_BLOCK_0___amp; again/`), `` $` `` and `$'` spliced in the
surrounding document, and `$$` collapsed to a single `$`.
Pass a function replacer at all four sites, matching the inline-code site
below them, which was already fixed this way. A function's return value is
inserted verbatim with no `$` interpretation.
The inline-code comment claimed `echo $1` would be read as a back-reference;
with a string search value there are no capture groups, so `$1` is already
literal. Reworded to name the four sequences that do corrupt.
Fixes#5663
* feat(models): define capability schema and readers
* fix(models): harden Google catalog probing
Restrict native catalog probing to the Gemini host, keep provider keys out of request URLs, filter non-chat model resources, and preserve the manual refresh default in the built-in Google add flow.
* docs: update static/js/MODULE_SUMMARY.md to reflect current ES6 frontend
Rewrite the stale module summary to match the current no-build,
ES6-module frontend architecture. Adds coverage of app.js orchestration,
the chat/SSE pipeline (chat.js, chatStream.js, chatRenderer.js,
streamingRenderer.js), new subsystems (research/, compare/, document
streaming, cookbook*, skills.js), and removes the obsolete <script> load
order assumptions.
* cleanup: remove dead MEMORY_DOC / memory_doc paths (closes#4411)
Removes the unused MEMORY_DOC constant and the matching DataConfig
memory_doc field / set_data_paths entry. No runtime code imports or
references these paths, so this is a no-behavior-change dead-code
cleanup under the storage-architecture tracker #4377.
Setting epSel.value triggered an async change event whose handler
called refreshModels('') — wiping the correct model selection that
refreshModels(settings.default_model) had just applied moments earlier.
The dropdown silently fell back to the alphabetically-first model
(deepseek-v4-flash instead of qwen-3.6-35B-A3B).
Moved the change listener registration to after the settings block
so the async change event fires before any listener exists. The
utility and teacher sections already followed this pattern.
