Real bugs: - loadArticle()/loadAuthorView() had no stale-render guard (unlike loadArticleList()/loadSearch()) -- a slower, superseded request could overwrite a newer one's render. Both now capture and check a generation snapshot. - #post/... links interpolated article.hash (raw, unencoded "author/slug") directly, but router.js unconditionally decodeURIComponent()s each segment when parsing -- would throw (silently swallowed) for any author/slug containing a literal "%" or other reserved character. Links now go through a new postHref() helper that encodes each segment individually. - A startup failure replaced the entire document.body, which would wipe out a host site's own page content when cmjs is embedded alongside it. Now scoped to cmjs's own mount points when at least one exists. - hydrateArticle() had no in-flight de-duplication -- two concurrent callers for the same not-yet-hydrated stub (e.g. a page's hydration racing the next page's prefetch) could each fire a duplicate fetch. Now tracked via a WeakMap keyed by the stub. - Leftover "expedition blog"/"expedition year" wording missed by the earlier astronomy-club genericization pass (that pass's grep didn't cover the English word "expedition"). Robustness gaps: - cache.js no longer permanently disables the whole IndexedDB cache after a single failed transaction -- only openDb() itself failing does that now. - Listing mtimes are normalized to minute precision at the one point they enter the system, so cache comparisons stay consistent even if a server flips between JSON and HTML-fallback autoindex. - The root author-listing fetch failing outright is now treated like "every author's listing failed" (a new rootFailed crawl stat) instead of surfacing a generic, less-specific error. - router.js now checks both required mount points exist right after startup and fails with a clear, catchable message instead of a bare TypeError the first time showListView()/showArticleView() runs. - The article view's "back" link now returns to whatever list/search/ filter page the user actually came from (tracked via lastListHash) instead of always resetting to page 1 of everything. - filterLabel() now checks filter.type === 'category' explicitly instead of falling through to it as the default case. - Author-name filtering is now case-sensitive, matching how author paths/profile lookups are looked up everywhere else. - Documented (in code comments and a new README note) that article/bio Markdown renders via marked.js with no HTML-sanitization pass -- only trusted authors should be adding content. Minor: - Extracted applyArticleMetaFields() to share the date/reading-time/ category-badge logic between renderCard() and loadArticle() instead of duplicating it. - Clarified resolveMediaUrl()'s WordPress-migration special case as legacy compatibility, not a general-purpose feature. - frontmatter.js no longer requires a trailing newline after the closing "---" -- a file that's nothing but frontmatter now parses instead of falling through to "no frontmatter at all".
