This is task state, not ambient context. Follow `AGENTS.md`; claim one task ID,
record blockers/decisions under it, and check it off only with evidence.
## Established boundary
openbim-core plus openbim-codec-zip/xml. No IFC dependency for the format itself.
## Open work
See `docs/ROADMAP.md` Stage 5 for sequencing. Nothing is claimed here yet.
## Planned file map
These paths are compiled private scaffold modules. Implement inside the named
owner and expose a public symbol only through an intentional parent re-export.
- (none claimed yet)
## Work queue
- [ ] `BCF-READ` - tolerant BCF reader validated against the measured third-party corpus
## Completion log
Nothing completed yet. Record the proof command and its result here when an
item above is checked off.
