Risk: EDS files in the wild are inconsistent RISK_0020
status: open
links outgoing: REQ_0725

Vendor EDS exporters historically produce subtly different dialects (LineFeed key variations, comment styles, value trimming). Mitigation is the liberal-parser policy (Liberal parsing — warn and ... (REQ_0725)) — warn and continue rather than reject. The parser will accumulate fixture exposure to known-quirky files over time; the warning channel makes regressions visible.
Risk: serde-ini ecosystem thinness RISK_0021
status: open
links outgoing: ADR_0081, REQ_0722

The Rust serde-INI ecosystem is less mature than serde-XML. Both candidate crates (serde_ini, rust-ini) have small maintainer pools. Mitigation: the façade pattern in INI backend choice — serde-... (ADR_0081) ensures the IR survives a backend swap, and the parser surface (parse(text) -> Result<EdsFile, EdsError>) is small enough that a worst-case fork or replacement is low-effort.
Risk: CiA 301 OD blow-up on profile-rich devices RISK_0022
status: open
links outgoing: REQ_0747, ADR_0075

CiA 402 servo drives and similar profile-rich devices carry 200+ OD entries. Generating the full OD table per device would balloon the codegen artefact by an order of magnitude. Mitigation: OD emission is feature-gated default-off (Object dictionary emission ... (REQ_0747) mirroring Object dictionary as static... (ADR_0075)); the EtherCAT side has already proven this approach for OD-heavy Beckhoff modules (cf. OD table size blow-up on co... (RISK_0010)).
Risk: COB-ID base assumptions in generated code RISK_0023
status: open
links outgoing: REQ_0753

Generated code computes PdoOut::can_id from the current node_id() and the EDS-declared base COB-ID. Devices that deviate from CANopen’s default COB-ID assignment scheme (e.g. manually-overridden bus layouts) would produce wrong CAN IDs. Mitigation: the EDS already carries the base COB-ID per PDO communication entry; deviations show up as a value other than the default. The DCF follow-on (NO DCF support this round (REQ_0790)) is the right place to thread per-bus overrides; this round honestly inherits whatever the EDS declares.
