Known Limitations and Human-in-the-Loop Boundaries
TIPSY Boundary
BatchTIPSY/BTC remains an external proprietary runtime boundary.
FEMIC now supports a tracked unattended BTC /TSR seam on Windows through the live user-overlay
TimberSupply.rptpath.The external-boundary caveat is now about the proprietary Windows tool and its report/runtime quirks, not about a hard requirement for routine manual button-clicking in the supported FEMIC path.
For unattended BTC work, the supported FEMIC seam is the live /TSR user-overlay report path. BTC /No_GUI is not a supported FEMIC workflow.
FAN$IER Boundary
FAN$IER automation is now real, but it remains Windows GUI automation around a proprietary application, not a native CLI/runtime contract.
FEMIC can launch unattended batch extraction and parse the resulting reports, but this seam should still be treated as a fragile external runtime boundary.
Data Vendor/Format Constraints
Some BC datasets are delivered in formats that require special extraction or conversion tooling.
Dataset vintages can change fields and behavior; source validation is required before swapping vintages in production workflows.
Modeling Limitations
Small-area units can break stratification assumptions tuned for large TSA-scale BC management units and may need explicit FMU-local tuning.
SI signal may appear weak without careful split/merge and fit controls.
Species-wise managed trajectories may require explicit tuning when vendor outputs are inconsistent with scenario intent.
Documentation Scope Boundary
Published Sphinx docs are user/developer guides and reference contracts.
Large proprietary PDFs and ad hoc source material are stored under
reference/and are not republished through Sphinx pages.
