A teammate's agent rewrites a file and yours never hears about it — the only trace is a `.bdrive-conflict-*` nobody opens. Now the turn-start hook names the paths that arrived since the last turn: "re-read before editing". The record lives in a spool (`internal/store/inbound.go`), not in Cycle's Result, because the daemon usually materializes a peer's change seconds before the turn starts — so the hook's own cycle sees nothing. materialize appends every path it writes or removes, `bdrive sync --hook` drains it after its cycle and renders it under each mount's own prefix (stripping the session subpath when the run is inside a mount, dropping paths outside it). Advisory only: nothing blocks, nothing prompts, no per-Write remote call. The spool is capped, 0600, in the volume dir, and best-effort everywhere — a spool failure never fails a cycle or a turn.

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).
