[[guide]] rendered as href="wiki:guide" — a pseudo-scheme no browser can resolve. The delegated click handler rescued a plain left-click, so the feature looked fine until someone copied the link, middle-clicked it, or opened it in a new tab and got a dead string. Resolution moves from click time to transform time: transformHTML (the pass that already rewrites this HTML before the mount) matches the target against flatFiles and writes the real urlForPath() URL, plus a data-wiki marker. A wikilink matching no file loses its href entirely and renders as .wiki-missing, so no "wiki:" survives into the DOM either way. The matching rules didn't change — they moved into a pure resolveWiki() in util.ts, where node --test covers the whole matrix without a browser. The consequence to get right is the click: real hrefs mean a plain click must be intercepted (or it does a full document load) and every modified click must be let through (or the fix buys nothing) — the same rule nav.ts:linkProps applies everywhere else. The guard sits above both branches, so cmd-clicking a relative markdown link now opens a tab too instead of SPA-navigating the current one. markdown.go is unchanged: wiki: stays the marker the server leaves behind because RenderMarkdown has no file tree. /s/<token> share pages keep their dead wikilinks by the spec's decision — the target isn't part of the share.

Architecture diagrams
Mermaid diagrams of the current implementation, kept next to the code so PRs can update them alongside the change.
Convention: when a PR changes the structure drawn here (new/removed types, new seams, changed relationships), update the affected diagram in the same PR and add an "Architecture changes" section to the PR description that, per changed diagram:
- names exactly which types/relationships changed and how (one sentence);
- shows a Before and an After mermaid block — each an excerpt of only the affected classes and their immediate relationships, never the full diagram (Before comes from the diagram at the merge base).
The committed diagram file stays the full current state; the before/after
excerpts exist only in the PR description so reviewers see the structural
delta at a glance. A pre-PR hook (.claude/hooks/check-arch-diagrams.sh)
reminds Claude Code sessions when server code changed but no diagram did.
Together these cover every application package in the repo — every code change lands inside exactly one detail diagram's scope (plus the overview when the package map or cross-piece wiring changes):
- overview.md — system diagram: every package and surface on one page, and how they connect
- cli-sync.md — class diagram of the CLI and sync engine (
cmd/bdrive+internal/{syncer,store,journal,config,daemon,agenthooks,autostart}) - webapp-server.md — class diagram of the
bdrive serveserver (internal/webapp+ itsinternal/remoteseam) - webapp-frontend.md — module diagram of the hub's React SPA (
internal/webapp/frontend/src)
Not covered on purpose: web/docs (content site, no application code) and
cloud/ (private nested repo — its architecture lives there).
